About This Prospectus

Following this offering, Medline Holdings will be the predecessor of Medline Inc. for financial reporting purposes. Immediately following this offering, Medline Inc. will be a holding company, and its sole material assets will be its equity interests held directly or indirectly through wholly owned subsidiaries in Medline Holdings. As the general partner of Medline Holdings, Medline Inc. will operate and control all of the business and affairs of Medline Holdings and, through Medline Holdings and its subsidiaries, conduct our business. The Reorganization Transactions (as defined herein) lack economic substance and therefore will be accounted for in a manner consistent with a reorganization of entities under common control. As a result, the consolidated financial statements of Medline Inc. will recognize the assets and liabilities received in the Reorganization Transactions at their historical carrying amounts, as reflected in the historical financial statements of Medline Holdings. Medline Inc. will consolidate Medline Holdings on its consolidated financial statements and record a non-controlling interest related to the Units (as defined herein) held by the Continuing Unitholders (as defined herein) on its consolidated balance sheet and statement of comprehensive income. See “Organizational Structure.”

The historical financial information of Medline Inc. has not been included in this prospectus as it is a newly incorporated entity, has no business transactions or activities to date, and had no assets or liabilities during the periods presented in this prospectus.

Certain monetary amounts, percentages, and other figures included in this prospectus have been subject to rounding adjustments. Percentage amounts included in this prospectus have been calculated, in some cases, not on the basis of such rounded figures, but on the basis of such amounts prior to rounding. For this reason, percentage amounts in this prospectus may vary from those obtained by performing the same calculations using the figures, on the face of our consolidated financial statements included elsewhere in this prospectus. Certain other amounts that appear in this prospectus may not sum due to rounding.

In December 2024, we changed the name of Medline Holdings from Mozart Holdings, LP to Medline Holdings, LP. We will not distinguish between the prior and current name of Medline Holdings and will refer to the current name of Medline Holdings throughout this prospectus. References in this prospectus to “Medline,” the “Company,” “we,” “us,” and “our” refer (1) prior to the consummation of the Offering Transactions (as defined herein), to Medline Holdings, LP and its consolidated subsidiaries and (2) after the Offering Transactions to Medline Inc. and its consolidated subsidiaries.

Our Prime Vendor model began in the acute care channel and, as these hospitals expanded into other sites of care, we have extended this model into the non-acute space to include those affiliated sites of care (“acute affiliated”). For purposes of the Prime Vendor data within this prospectus, we are only including those customers that are acute and acute affiliated.

Over time, we have also entered into Prime Vendor agreements with facilities that are non-acute and not affiliated with a hospital system (i.e., not acute affiliated). Data in this prospectus does not include Prime Vendor relationships outside of acute and acute affiliated.

Letter from the Mills Family For nearly six decades, and through three generations, Medline has been built on a foundation of listening to customers. In 1966, Jim and Jon Mills founded Medline, and soon after opened our first textile manufacturing facility in Indiana. They were building on the legacy of their grandfather A.L. Mills, who during World War I responded to requests from nuns at Mercy Hospital in Chicago to manufacture surgeons gowns and uniforms at his company, Mills Hospital Supply. Ever since, we have innovated and manufactured products in support of doctors, nurses, and patientsfrom our well-recognized pink and blue baby blankets, to our surgical kits and trays, and beyond. Medline is dedicated to making healthcare run better and more affordably. Our consistent growth has been fueled by our belief in doing the right thing and focusing on the long-term health of our customers, colleagues, and shareholders. We are proud to see our products providing care in hospitals, surgery centers, labs, long-term care facilities and doctors offices across America and around the world. In the late 1990s, Charlie Mills succeeded Jim as Chief Executive Officer and began leading Medline alongside Jons son Andy as President and son-in-law Jim Abrams as Chief Operating Officer. Under our leadership, the company consistently evolved to serve our customers. We built the Medline Brand segment to drive savings and value, we entered the Prime Vendor distribution business to address unmet customer needs, we invested in robust distribution centers to deliver best-in-class service levels, and we launched our dedicated transportation fleet to enhance our resilience and ability to serve our customers. Our end-to-end supply chain allows Medline to deliver extraordinary service and value. Truly understanding our customers needs has informed how we have expanded our product portfolio and service offerings. Our customer-centric focus remains the foundation of Medlines purpose today, and we take great pride in our longstanding customer relationships. No one embodies Medlines values more than Jim Boyle, our Chief Executive Officer. As part of our succession strategy, we appointed Jim to lead the team as CEO in 2023. Jim joined Medline as a sales representative in Texas 28 years ago and worked his way up through the organization, ultimately running our commercial and operations teams, serving and supporting our entire customer base. Jim has been instrumental in helping us develop and expand our capabilities all the way back to our initial Prime Vendor relationship in 1996, which was a relationship that he managed. Over Jims career, we have seen him foster our culture and drive operational excellence. We have deep confidence Jim will continue to lead Medline with focused purpose. We are grateful to our customers, partners, and colleagues who have shaped Medline through the years, and we are honored to support healthcare providers each and every day. We hope you will join us for the next chapter of Medlines story, which promises to be as transformational as the last. - Charlie Mills, Andy Mills, Jim Abrams

Letter from our CEO While much has changed since I joined Medline 28 years ago, our operating philosophy remains the same: to provide high-quality, low-cost products and services to our healthcare customers. Simply put, our goal is to get the right medical-surgical products to the right place, at the right time, and at the right value, so that our customers can ultimately deliver the best patient care. Over the last six decades, Medline has invested heavily to create a broad product portfolio, scaled infrastructure, and a resilient, robust supply chain for our customers. This footprint includes 68 global distribution centers with over 28 million square feet of space, 27 manufacturing facilities, and an owned fleet of over 2,000 MedTrans delivery trucks. In addition, during that time, our Medline Brand product portfolio has expanded from just a few categories to approximately 190,000 products across 250 product families as to December 31, 2024. Together, this enables us to maintain best-in-class service levels with next-day delivery for 95% of our U.S. customers and to offer the best total value for our customers. Perhaps most importantly, we have a deep understanding of our customers operations, and we work side-by-side to develop truly integrated partnerships, rather than simply serving as a transactional supplier. I joined Medline very early in my career, and I feel fortunate to have had the opportunity to grow and learn alongside an incredible group of colleagues. One of the main reasons I joined Medline and still love it here today is our culture of customer focus, entrepreneurial spirit, and individual empowerment. Every day Im inspired by our teams collective drive and our understanding that we are all part of something much bigger. Our relentless focus on the customer is what propelled Medline to where we are today and what will keep us headed in the right direction for years to come. We build long-lasting relationships with our customers and never take them for granted. We believe we must earn the right to serve our customers and do so through a gritty, agile, and flexible approach. We set high expectations for ourselves and bring an intense focus on cost, quality, and creativity to each customer challenge, product, and service innovation. We have delivered annual consecutive net sales growth since inception, because everything we do starts and ends with serving our customers. Becoming a public company is a responsibility that we take seriously. We will create value for our shareholders through our relentless customer focus, stellar execution, and commitment to long-term success. It is an honor to serve as CEO of Medline. You have my commitment that we will continue to prioritize our customers and partners, operate openly and transparently, and conduct ourselves with humility and integrity. Thank you to our more than 38,000 employees whose pride in their work, ambitious problem solving, and dedication make Medline the enduring and special place that it is. Our people remain our greatest competitive advantage. Finally, and most importantly, we express our deepest gratitude to our customers around the world. You are our purpose. Thank you for the trust you place in us. - Jim Boyle

RISK FACTORS

Investing in our Class A common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below and the other information set forth in this prospectus before deciding to invest in shares of our common stock. If any of the following risks actually occur, our business, results of operation, financial condition, cash flows, and prospects may be materially adversely affected. The risks and uncertainties described below are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially and adversely affect our business, results of operations, and financial condition. In such case, the trading price of our common stock could decline and you may lose all or part of your investment. The risks discussed below also include forward-looking statements, and our actual results may differ substantially from those discussed in these forward-looking statements. See “Forward-Looking Statements” in this prospectus.

Risks Related to Our Business, Industry and Operations

Our global operations are subject to inherent risks that could materially adversely affect our business, results of operations, and financial condition.

Our global operations are subject to risks that may materially adversely affect our business, results of operations, and financial condition. We import a significant percentage of our Medline Brand products from outside of the United States, including 8% of our costs of goods sold from China for the year ended December 31, 2024. As a result of our global operations, we may experience, among other things:

30

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

See also “—Uncertain global and domestic macro-economic and political conditions could materially adversely affect our business, results of operations, and financial condition.”

We may be unable to derive fully the anticipated benefits from our existing or future acquisitions, joint ventures, investments, dispositions, or other strategic transactions.

Acquisitions, joint ventures, investments, dispositions, and other strategic transactions are an important part of our strategy to expand and enhance our products, services, and customer base and to enter new geographic areas. We are regularly in negotiations for potential acquisitions, joint ventures, investments, dispositions, and other strategic transactions.

As we continue pursuing selective acquisitions, strategic investments, partnerships, or alliances with third parties to support our business and growth strategy, we may not be able to identify suitable acquisition, strategic investment, partnership, or alliance candidates on favorable terms, if at all. We may use a combination of additional debt, securities issuances, revolver borrowings, and/or cash on hand to finance such transactions.

We may also decide from time to time to dispose of assets or businesses. We may encounter difficulty finding buyers or alternative exit strategies, fail to obtain necessary regulatory approval, or incur higher costs or charges than planned or unexpected charges. Future dispositions or divestitures may not occur within the anticipated timeframe or at all. Completed divestitures may also result in continued financial involvement in the divested business, such as through transition services arrangements, guarantees, indemnifications, or other financial arrangements, following the transaction.

These transactions may involve challenges and risks. For example, acquisitions, strategic investments, partnerships, or alliances with third parties are subject to various antitrust, unfair trade practices, and/or consumer protection laws. More stringent interpretation of these existing laws or regulations, as well as future laws or regulations, could negatively impact our growth prospects. The process of exploring strategic transactions or selling a business could also negatively impact customer decision-making and cause uncertainty and negatively impact our ability to attract, retain, and motivate key employees. Any failures or delays in completing strategic transactions, dispositions, or divestitures could have an adverse effect on our business, financial condition, and results of operations, and on our ability to execute our strategy. In addition, we expend costs and management resources to pursue and complete strategic transactions and divestitures and manage post-closing arrangements. If a transaction does occur, we may not be able to realize any value created by the transaction.

Consolidation in the healthcare industry could have an adverse effect on our business, results of operations, and financial condition.

Many healthcare industry companies, including healthcare systems, distributors, manufacturers, suppliers, providers, and insurers, are consolidating or have formed strategic alliances. We expect that market demand,

31

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

government regulation, third-party coverage and reimbursement policies, and societal pressures will continue to change the healthcare industry worldwide, resulting in further business consolidations and alliances among our customers. Although we believe consolidation in the healthcare industry represents a potential market opportunity as discussed in the “Summary” and “Business” sections, the effects of this consolidation on our business may be unpredictable and could have a material adverse effect on our business, results of operations, and financial condition. For example, competition to provide goods and services to industry participants will become more intense. Additionally, our existing customers, including our Prime Vendor customers, may consolidate with industry participants that do not use our services or purchase our products, resulting in the loss of customer relationships. Further, this consolidation creates larger enterprises with greater negotiating power, which they can use to negotiate price concessions. If we must reduce our prices because of industry consolidation, or if we lose customers as a result of their consolidation with other industry participants, our business, results of operations, and financial condition could be materially adversely affected.

We operate in a highly competitive industry, with accelerating pricing pressure and changes in technology.

The med-surg industry is highly competitive and characterized by pricing and margin pressure for our business. We compete with other medical product manufacturers and distributors, as well as customer self-distribution models and outsourced logistics companies. We compete on a range of factors, including market pricing, negotiating with provider networks and Group Purchasing Organizations (“GPOs”), total delivered product cost, product availability, the ability to fill and invoice orders accurately, delivery time, range of services provided, efficient product sourcing, inventory management, information technology, electronic commerce capabilities, and the ability to meet customer-specific requirements and preferences. In certain channels, competitors may have other products and services that are, or are perceived to be, superior to our own. Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our revenue and margins. The cost of our efforts to manage these competitive pressures, or our inability to compete effectively with respect to them, could have a material adverse effect on our business, results of operations, and financial condition.

Traditional distribution relationships are being challenged by online commerce solutions. Such competition requires us to adapt to changing technology, continue to provide enhanced service offerings, and continue to develop ways to differentiate our business to address demands of consumers and customers on a timely basis, which may require us to incur significant costs. Additionally, when we sell products through large online commerce solutions, such as Amazon, we forfeit our ability to establish pricing or differentiate in placement among competitor products and are required to pay a portion of the sale to the online commerce solution. The emergence of such competition and our inability to anticipate and effectively respond to changes on a timely basis could have a material adverse effect on our business.

Our inability to anticipate or adapt to major changes in available technology, benefit or coverage policies related to those changes, or the preferences of customers may cause our current product offerings to become less competitive or obsolete or require significant strategic changes. This, in turn, could cause us to incur increased capital expenditures and could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

Furthermore, our ability to compete effectively is increasingly dependent on access to and interpretation of data. Data quality impacts customer ordering, order fulfillment, and higher order processing. If we fail to effectively implement and maintain data governance structures across our businesses or to effectively interpret and utilize such data, our operations could be impacted and we may be at a competitive disadvantage.

Changes to the U.S. and global healthcare environments may not be favorable to us.

The U.S. healthcare industry is subject to continued changes in public policy, laws, and regulations, including changes governing healthcare services, healthcare coverage, mandated benefits, efforts to promote increased transparency in the supply chain, further reduction of, or limitations on, governmental funding at the

32

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

state or federal level, or efforts by healthcare insurance companies to further limit payments for products and services. The industry has undergone, is undergoing, and is expected to further undergo significant changes. These changes may include, and have previously included, declines in Medicare and Medicaid spending and reimbursement levels, changes to eligibility and enrollment that result in individuals becoming uninsured, hospital and healthcare facility closures, hospitals reducing or eliminating certain lines of service and staff, changes to provider taxes, pricing reforms, efforts by healthcare insurance companies to limit or reduce payments to pharmacies and providers, the basis for payments beginning to transition from a fee-for-service model to value-based payments and risk-sharing models, and the industry shifting away from traditional healthcare venues like hospitals and into clinics, physician offices, and patients’ homes, and other potential changes. The impact of newly enacted laws, future legislative proposals, and executive orders that may bring significant changes to the healthcare industry is uncertain. These possible changes, and the uncertainty surrounding them, may limit our negotiating power, the prices we are able to charge for our products, the amounts of reimbursement for our products, or our ability to develop new products, which could have a material adverse effect on our business, results of operations, and financial condition.

The healthcare industry outside the United States is also subject to continuous and significant changes, including changes, actions, and proposals by governments, regulators, and third-party payers to control healthcare costs and, more generally, to reform healthcare systems. Certain of these actions and proposals could, among other things, limit the prices we are able to charge for our products or the amounts of reimbursement available for our products and could limit the acceptance and availability of our products in a variety of international markets. These actions and proposals could have an adverse effect on our business, results of operations, and financial condition.

Increases in shipping costs or service issues with our third-party shippers could harm our business.

Our ability to meet our customers’ expedited delivery expectations is an integral component of our business strategy on which our customers rely. Shipping is a significant expense in the operation of our business, and we bear the cost of the majority of our freight expense. Global capacity challenges, port congestion, and equipment displacement continue to create upward pressure on import costs. Accordingly, any significant increase in shipping rates and times could have a material adverse effect on our business, results of operations, and financial condition. For example, in 2022, we experienced increases in freight expenses, which negatively impacted our results of operations. Higher freight expenses may continue to negatively affect our results of operations in the future. Further, the conflicts in the Middle East, such as the Israel-Hamas war, Ukraine, and other regions have brought, and could further bring about, disruption, instability, and volatility in global markets, supply chains, and logistics operations, including the current shipping disruptions and related shipping cost increases in the Red Sea and surrounding waterways, which could in turn adversely affect our business operations and financial performance. Similarly, strikes or other service interruptions affecting our third-party shippers, including at transportation centers or shipping ports, could cause our operating expenses to rise and materially adversely affect our ability to obtain materials and deliver products on a timely basis.

Significant challenges or delays in our sourcing of new products and technologies could have an adverse impact on our long-term success.

Our continued growth and success depends on our ability to source new and differentiated products and services that address the evolving healthcare needs of patients, providers, and consumers. Sourcing successful products and technologies is also necessary to offset revenue losses when our existing products lose sales due to various factors such as competition and loss of patent exclusivity. New products or enhancements to existing products may not be accepted quickly or significantly in the marketplace due to product and price competition, changes in customer preferences or healthcare purchasing patterns, resistance by healthcare providers, or uncertainty over third-party reimbursement. We cannot be certain when or whether we will be able to source, license, or otherwise acquire products and technologies; whether potential products will be granted regulatory clearance, authorization, or certification; and, if cleared, authorized, or certified, how long the clearance,

33

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

authorization, or certification of a product might take to complete or whether such products will be commercially successful.

We have concentration in and dependence on certain healthcare provider customers and GPOs.

For the year ended December 31, 2024, our top five U.S. customers represented approximately $2.6 billion (or 10.4%) of our net sales. In addition, for the year ended December 31, 2024, approximately $17.1 billion (or 67% of consolidated net sales and 72% of U.S. net sales) was from sales to member hospitals under contract with our largest GPOs: Vizient Supply, LLC, Premier Healthcare Alliance, L.P., and HealthTrust Purchasing Group, L.P. We could lose a significant healthcare provider customer if an existing contract expires without being replaced or is terminated by the customer prior to its expiration. Although the termination of our relationship with a given GPO would not necessarily result in the loss of the member hospitals as customers, any such termination of a GPO relationship, or a significant individual healthcare provider customer relationship, could have a material adverse effect on our business, results of operations, and financial condition.

We may be unable to attract, develop, and retain key employees.

Our sales, technical, and other key personnel play an integral role in the development, marketing, and selling of new and existing products. Our ability to attract, engage, develop, and retain qualified and experienced employees, including key executives and other talent, is essential for us to meet our strategic business objectives. We compete with many other businesses to attract and retain employees. Competition among potential employers might result in increased salaries, benefits, or other employee-related costs. Additionally, we have observed an overall tightening and increasingly competitive labor market due to labor shortages caused in part by the COVID-19 pandemic and responsive measures, inflationary pressures and other macroeconomic factors including increased wages offered by other employers, and voluntary attrition of our employees and the employees of our third-party suppliers, manufacturers, distributors, and customers. If we are unable to maintain competitive and equitable compensation and benefit programs and practices that meet the expectations of our employees, including incentive programs that reward financial and operational performance, remote and hybrid work practices, flexible and alternative work arrangements, and corporate responsibility practices, our ability to recruit, hire, engage, motivate, and retain talent could be negatively affected. Furthermore, we may be unable to maintain an inclusive culture that aligns our diverse work force with our mission and values, or we may suffer negative perception of our belonging initiatives due to our perceived over or under pursuit of such initiatives. We have experienced and could continue to experience further or increased attempts to unionize portions of our workforce. Finally, any of these risks could increase our labor costs, harm our culture, decrease employee engagement, create legal costs, or damage our reputation, all of which could negatively impact our ability to attract, hire, develop, and retain a talented, competitive, and highly skilled workforce and have a material adverse effect on our business, results of operations, and financial condition.

We may also experience sudden loss of key personnel due to a variety of causes, such as illness or the competitive factors above. Our ability to effectively succession plan, and to execute such plans, is also important to our long-term success. In addition, recent legal and regulatory changes affect our ability to enforce post-termination obligations from certain employees with respect to non-competition, non-solicitation, and protection of confidential information, which may negatively impact our ability to retain employees and protect our information and relationships with customers and other third parties.

Our business and operations depend on the proper functioning of our critical facilities and distribution networks and could be negatively impacted by events outside our control.

Our business depends on the proper functioning of our business processes and critical facilities and our logistics and distribution networks as well as those of our third-party suppliers. We have a differentiated network of 33 manufacturing facilities, 69 global distribution facilities, and a fleet of more than 2,000 MedTrans trucks. Disruptions impacting our critical facilities or our logistics and distribution networks, including those caused by

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

infrastructure, information, and equipment malfunction; failure to follow specific protocols and procedures; facility shutdowns; recalls or quality problems; failure to properly control inventory; actions either required or determined to be taken to cease shipments in response to regulatory requests, pressure, actions or safety issues; regulatory enforcement actions; increased shipping times; defective raw materials; labor shortages; tariffs or other import or export restrictions; natural disasters such as hurricanes, tornadoes, earthquakes, or wildfires; property damage, including from riots and other environmental factors; the impact of epidemics, pandemics, or other public health crises, and actions by businesses, communities, and governments in response could adversely affect our business, results of operations, and financial condition and damage to our reputation. We also incur costs to remediate these disruptions, and it is possible that these costs could be significant.

We may be required to recognize impairment charges related to goodwill, identified intangible assets, and fixed assets that would reduce our reported assets and earnings.

Goodwill and other identifiable intangible assets comprise a substantial portion of our total assets. There is significant judgment required in the analysis of a potential impairment of goodwill, identified intangible assets and fixed assets. If, as a result of a general economic slowdown, deterioration in one or more of the markets in which we operate or impairment in our financial performance and/or future outlook, the estimated fair value of our long-lived assets decreases, we may determine that one or more of our long-lived assets is impaired. Recognition of an impairment would reduce our reported assets and earnings, and any such impairment charge could have a material adverse effect on our business, results of operations, and financial condition.

We may not realize the expected benefits from the entry into new or amended contracts, planned cost savings, and business improvement initiatives.

We often enter into new or expanded contracts with customers. Although we may expect to realize substantial benefits from such contracts, we may not be successful with this strategy, or we may not realize all of the benefits we expect from such contracts. Additionally, our cost savings and business improvement initiatives could result in unexpected charges and expenses that negatively impact our financial results, and we could fail to achieve the desired efficiencies and estimated cost savings. If we are not able to effectively implement these initiatives, including outsourcing or similar third-party relationships, or if they fail to operate as intended, our financial results could be adversely affected. These types of initiatives could also yield unintended consequences such as distraction of management and employees, business disruption, and an inability to attract or retain key personnel, which could negatively affect our business or financial condition and results of operations.

Quality problems and product liability claims have in the past led, and could in the future lead, to recalls or safety alerts, reputational harm, adverse verdicts, or costly settlements, and could have a material adverse effect on our business, results of operations, and financial condition.

Quality is extremely important to us and our customers due to the impact on patients and healthcare providers and the serious and potentially costly consequences of product failure. Our business exposes us to potential product liability risks that are inherent in the design, manufacture, and marketing of med-surg products. Component failures, manufacturing nonconformances, design defects, quality problems, off-label use, regulatory noncompliance, or inadequate disclosure of product-related risks or product-related information with respect to our products, whether manufactured by Medline or our third-party manufacturers, or products of other manufacturers that have been incorporated into our surgical and procedural kits, have occurred and may occur in the future and have resulted in and may result in product recalls, notifications to affected customers, and other corrective actions. Such issues, if they were to occur in the future, may result in adverse reactions, an unsafe condition, or personal injury or death. Such issues may lead to a recall of, or the issuance of a safety alert relating to, such products, and could also result in product liability claims and lawsuits, including class actions.

Strong product quality is critical to the success of our goods and services. If we or our third-party manufacturers fall short of these standards and our products are the subject of recalls or safety alerts, our

35

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

reputation could be damaged, we could lose customers, and our revenue and results of operations could decline. Reputational value is based in large part on perceptions of subjective qualities, including the perception of our employees. Even an isolated incident, or the aggregate effect of individually insignificant incidents, can erode trust and confidence, particularly if they result in adverse publicity, governmental investigations, or litigation, and as a result, could tarnish our brand and lead to adverse effects on our business, financial condition, and results of operations. In certain situations, we may undertake a voluntary recall or market withdrawal of products or temporarily shut down production lines based on performance relative to our own internal safety and quality monitoring and testing data or based on data from governmental or regulatory authorities or our third-party manufacturers.

Any such problems, including quality issues at our third-party manufacturers, past and future product liability claims, recalls, market withdrawals, or safety alerts, regardless of their ultimate outcome, could harm our reputation and have a material adverse effect on our business, results of operations, and financial condition.

Our failure to establish and maintain Prime Vendor relationships may cause our revenue to decline.

Our ability to earn Prime Vendor agreements is an important revenue driver for us. Our active Prime Vendor agreements as of December 31, 2024 generated approximately 62.9% ($16.0 billion) of net sales for the year ended December 31, 2024. Certain of our Prime Vendor agreements provide for rights of termination for convenience. If we are unable to successfully establish new Prime Vendor agreements, maintain or expand our Prime Vendor relationships or if there is an actual or perceived decrease in the quality of service and care levels we provide to our Prime Vendor customers, our Prime Vendor relationships could be negatively impacted and revenues may decline.

As part of our growth strategy, we seek to drive customer savings through the conversion of Supply Chain Solutions products to like-for-like Medline Brand products, which we typically expect to have higher margins. There are no assurances that we will be successful in executing this strategy. Conversion of Supply Chain Solutions products to Medline Brand products will depend on a number of factors, many of which are not in our control, including our ability to successfully market Medline Brand products and Prime Vendor customer adoption of Medline Brand products. While we historically have earned higher margins upon conversion from third-party national brand products to like-for-like Medline Brand products, there are no assurances future conversions will yield similar margins. Additionally, because of the lower average prices for Medline Brand products, there is typically a negative impact on net sales upon the conversion of Supply Chain Solutions products to like-for-like Medline Brand products if volume is assumed to be constant. Moreover, for new Prime Vendor customers, Medline Brand products typically represent a lower portion of the customer’s product mix compared to existing Prime Vendor customers. As a result, our margins may be negatively impacted by sales to new Prime Vendor customers. If we are unable to effectively execute our conversion strategy, it could adversely impact our margins, as well as our business, financial condition, and results of operations.

If we experience increased pressure to maintain or decrease the price of our goods and services and we are unable to reduce our expenses, there may be a material adverse effect on our business, results of operations, and financial condition.

We have experienced, and may continue to experience, increased pressure to lower the prices for certain of our goods and services due to pricing pressure from managed care organizations and other third-party payers, increased market power of GPOs, IDNs and other customers, and increased competition among med-surg products and services providers. GPOs and IDNs negotiate pricing arrangements with medical product companies and distributors and then offer these negotiated prices to affiliated hospitals and other members. GPOs and IDNs typically award contracts on a category-by-category basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of driving down pricing or reducing the number of vendors. Due to the highly competitive nature of the GPO and IDN contracting processes, we may not be able to obtain new, or maintain existing, contract positions with major GPOs and IDNs. GPO contract positions do not

36

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

guarantee that any level of sales will be achieved, as members of the GPO are generally free to purchase from other suppliers, and any such purchases could result in a decline in our sales volumes and revenue. The formation of new provider networks and GPOs may shift purchasing decisions to entities or persons with whom we do not have a historical relationship. This may threaten our ability to compete effectively, which could in turn negatively impact our financial results. Although we may seek to obtain similar terms from manufacturers to obtain access to lower prices demanded by GPO contracts or other contracts, and to develop relationships with provider networks and new GPOs, we may not be able to secure such terms or execute such contracts. If we experience pressure to reduce the prices for our goods and services and we are unable to reduce our expenses, our business, results of operations, financial condition, and cash flows will be adversely affected.

Any failure by or loss of a third-party manufacturer or supplier or other manufacturing or supply-related impacts could result in delays and increased costs, which may adversely affect our business.

We rely on third parties to manufacture and supply certain raw materials, component parts, and finished goods. For example, we utilize a network of more than 500 global partners across a diversified set of approximately 40 countries for the vast majority of the other two-thirds of our Medline Brand products that are not manufactured at our manufacturing facilities, and, through our Supply Chain Solutions segment, we offer med-surg products from over 1,250 third-party suppliers. We depend on these third-party manufacturers to allocate a portion of their manufacturing capacity sufficient to meet our needs, to produce products of acceptable quality and at acceptable manufacturing yields, and to deliver those products to us on a timely basis and at acceptable prices. However, if these third-party manufacturers are unable to meet our near-term or long-term manufacturing requirements, it could result in lost sales and have a material adverse effect on our business, results of operations, and financial condition.

Our reliance on third parties for regulatory compliance and quality assurance, potential third-party misappropriation of our intellectual property, our limited ability to manage our inventory provided by third parties, the possibility of breach of manufacturing agreements by third parties, and the possibility of termination or nonrenewal of manufacturing agreements by third parties at a time that is costly or inconvenient for us could, among other things, adversely affect our ability to deliver our products on a timely basis, cause us to incur potentially substantial increased costs, or expose us to additional regulatory risk or litigation. Moreover, if any of our third-party manufacturers suffer any damage to facilities, lose benefits under their material agreements, experience power outages, encounter financial difficulties, are unable to secure necessary raw materials from their suppliers or suffer any other reduction in efficiency, experience a force majeure, or fail to comply with regulatory requirements, we may experience significant business disruption. In the event of any such disruption, we would need to seek and source other qualified third-party manufacturers, likely resulting in further delays and increased costs, which could have a material adverse effect on our business, results of operations, and financial condition. In certain cases we may not be able to establish additional or replacement suppliers or third-party manufacturers in a timely or cost-effective manner, partly as a result of U.S. Food and Drug Administration (“FDA”) and other regulations that require, among other things, qualification and registration of replacement suppliers and third-party manufacturers, regulatory clearance, authorization, or certification of the products that will be manufactured, and validation of materials, components, and processes prior to their use in or with our products. Reductions in staff or funding at FDA or other medical product regulators may also affect the review, qualification, clearance, authorization or certification of additional or replacement suppliers or third-party manufacturers.

We also manufacture certain of our own products and contract manufacture products for others, which requires the availability of labor and the timely delivery of a sufficient amount of quality components and materials from third-party suppliers. For reasons including quality assurance, cost effectiveness, and the highly exacting and complex nature of manufacturing certain of these products, certain components, raw materials, and services needed to manufacture these products are obtained from a limited number of suppliers and have limited availability. Our supplier relationships could be interrupted, become less favorable to us, or be terminated, and the supply of these components, compounds, raw materials, or products could be interrupted or become insufficient.

37

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

In addition, for quality assurance or cost effectiveness, we have purchased from sole suppliers certain components and raw materials, such as polymers used in our Medline Brand products, and we expect to continue to purchase these components and raw materials from these sole suppliers. Although there are other sources in the marketplace for these items, we may not be able to quickly establish additional or replacement sources for certain components or materials due to regulations and requirements of the FDA, other regulatory authorities, and notified bodies regarding the manufacture of our products. The loss of any sole supplier or any sustained supply interruption or reduction in any manufacturing capabilities or processes that affects the ability to manufacture or distribute our products in a timely or cost-effective manner could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

Risks Related to Regulation and Legal Proceedings

We rely on the proper function, security, and availability of our information technology systems and data, as well as those of third parties throughout our global supply chain, to operate our business.

We are highly dependent on information technology networks and systems to operate our business and securely process, transmit and store any personally identifiable information (“Personal Data”), protected health information (“PHI”) and other sensitive and confidential data in connection with it, which includes our own proprietary applications and tools (e.g., PrefConnect and FitRight Connect) and a wide variety of third-party technologies. Our information technology networks and systems may also require integration with customers’ and other third parties’ systems and networks. We must regularly update and improve our IT systems and infrastructure and undertake investments in new IT systems and infrastructure. We cannot guarantee that our data security controls are sufficient or that the IT systems and infrastructure on which we depend, including those of third parties, will continue to meet our current and future business needs or adequately safeguard our operations. Security interruptions to or breaches, unauthorized access, acquisition, use, disclosure, theft, modification, or destruction of our information technology systems (or those of third parties working on our behalf, or data or Personal Data and PHI held therein), including physical or electronic break-ins, computer viruses, malware, ransomware, phishing, spoofing and other attacks by hackers, and similar breaches, or employee or contractor error, negligence, or malfeasance, have in the past, and may in the future, create system disruptions or shutdowns, result in unauthorized access to, or disclosure, misuse, modification, or loss or destruction of, our or our customers’ (or their members’ and patients’) or employees’ data, or result in damage, disablement, or encryption of our data or our customers’ (or their members and patients’) or employees’ data. Such data may include sensitive data or information, including PHI or other Personal Data. Any such incident that compromises the information of our customers or employees or disrupts our business operations could result in widespread negative publicity, damage to our reputation, a loss of customers, disruption of our business, operational delays, and legal liabilities. We utilize third-party service providers for important aspects of the collection, creation, receipt, maintenance, transmission, use, storage, retention, security, transfer, return, destruction, disclosure, and other operations (separately and collectively, “Processing” or “Process”) of employee and customer (and their members’ and patients’) Personal Data, PHI, and other confidential and sensitive information, and therefore rely on the security procedures of such third-party service providers with respect to such data, and they face the same risks as those set forth above.

We take certain administrative, physical, and technological safeguards to address data security risks, such as by requiring contractors and other third-party service providers who handle PHI, other Personal Data, and other confidential and sensitive information on our behalf to enter into agreements that obligate them to use reasonable efforts to safeguard such PHI, other Personal Data, and other confidential and sensitive information, and to comply with applicable laws regarding their Processing of such PHI and other Personal Data.

Measures taken to protect our systems, those of our contractors or third-party service providers, or the PHI, other Personal Data, or other confidential and sensitive information we, our contractors, or third-party service providers Process, may not adequately protect us from security risks. We have and may in the future be required to expend significant capital and other resources to protect against security breaches or to alleviate problems

38

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

caused by security breaches, regardless of whether such breaches are of our systems or networks, or the systems or networks of our customers, contractors, or third-party service providers. Any failure to so modify, upgrade, or replace such systems and networks, any disruptions that occur during the process of such modification, upgrade, or replacement and/or any breakdown, interruption, or corruption of our information technology systems and infrastructure could create system disruptions, shutdowns, delays in generating or the corruption or loss of data and information, or other disruptions that could result in negative financial, operational, business, or reputational consequences for us. Despite our implementation of data privacy and security measures, cyberattacks are becoming harder to detect and more frequent in recent years, in part because of the proliferation of new technologies and the increased sophistication and activities of organized crime, hackers, terrorists, activists, malicious state actors, and other internal and external parties. Further, these attacks are becoming increasingly sophisticated through the use of certain AI, automated decision-making and machine learning technology (collectively, “Machine Learning Technology”) and are often well-funded, including in some cases by state sponsors. As a result, we, our customers or our third-party service providers have and may in the future be unable to anticipate the techniques used to attack our or their systems or networks, or to implement adequate protective measures.

Security breaches, interruptions of systems, or other security incidents that we, our customers or our third-party service providers experience have and could in the future harm our reputation, compel us to comply with breach notification and other laws in all 50 U.S. states, and under applicable provisions of the Health Insurance Portability and Accountability Act of 1996, as amended, and the regulations that implement the law and its amendments (collectively, “HIPAA”), the EU’s General Data Protection Regulation and its UK equivalent (“UK GDPR” and collectively, “GDPR”) and other laws and regulations, expose us to legal and regulatory fines, penalties, and other liabilities, contract and indemnity obligations, and cause us to incur significant costs for investigations and remediation, notification to affected individuals, measures intended to repair or replace systems or technology and prevent future occurrences and potential increases in insurance premiums. If we are unable to prevent or mitigate security breaches, interruptions of systems, or other privacy or security incidents in the future, or to implement satisfactory remedial measures, or if it is perceived that we have been unable to do so, our operations could be disrupted, and we may suffer a loss of customers, reputation, and individual and investor confidence. Affected users (including customers or third parties) or government authorities could initiate legal or regulatory actions against us in connection with any privacy or security breaches or improper disclosures or Processing of data, which could cause us to incur significant expense and liability or result in orders or consent decrees, forcing us to modify our business practices.

Furthermore, if any of our critical suppliers or service providers is the target of a cybersecurity or ransomware attack or experiences any other kind of adverse event impacting relevant information technology systems, we could experience a significant disruption in our supply chain, unauthorized access or use of our information, shortages, disruptions to our financial reporting or other critical business functions, or other adverse consequences impacting our business operations. Notwithstanding the diligence that we perform on our service providers, we may not be in a position to verify the risks or reliability of their information technology systems or privacy and data security practices and protocols. Any such disruption or incident impacting our suppliers or service providers could have a material adverse effect on our business and may result in our incurring significant remediation costs.

While we maintain insurance covering certain business interruptions, cybersecurity-related damages and claim expenses, we may not carry insurance or maintain coverage sufficient to compensate for all liability, or all types of liability, or cover any indemnification claims against us relating to any security incident or, breach, disruption in information technology services. In any event, insurance coverage would not address the reputational damage that could result from a security incident. Moreover, we cannot be certain that insurance will continue to be available to us on commercially reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could adversely affect our business, financial condition, and results of operations.

We are subject to extensive and complex laws and governmental regulations and any adverse regulatory action may materially adversely affect our business, results of operations, and financial condition both inside and outside the United States.

Our products and technologies, as well as our business activities and government contracts, are subject to a complex set of regulations and rigorous enforcement, including by the FDA, the U.S. Department of Justice (“DOJ”), the U.S. Department of Health and Human Services (“HHS”) Office of the Inspector General, U.S. Environmental Protection Agency (“EPA”), and numerous other federal, state, and non-U.S. governmental authorities. To varying degrees, each of these authorities requires us, and our third-party manufacturers, to comply with laws and regulations governing the development, testing, manufacturing, registration, labeling, promotion, and distribution of our products. We cannot guarantee that we will be able to obtain or maintain the required marketing clearances, authorizations, or certifications to market our new products or for enhancements or modifications to existing products. Obtaining the necessary clearances, authorizations, or certifications may take a significant amount of time; require the expenditure of substantial resources; and limit the proposed uses of our products. The failure to obtain or maintain clearances, authorizations, and certifications could have a material adverse effect on our business, results of operations, and financial condition. Future laws and regulations may also have a material adverse effect on our business, results of operations, and financial condition. Additionally, significant changes to operations at, funding of, or restructuring of such governmental authorities, including but not limited to a government shutdown, decreases in staff who are able to review product submissions, reductions or other changes in funding provided to such governmental authorities, and changes in policy and enforcement priorities, may adversely affect our business.

Both before and after a product is commercially marketed, we have responsibilities under the FDA, the European Union Medical Device Regulation (“EU MDR”), and other applicable U.S. and non-U.S. regulations, including with respect to clinical studies, quality systems, manufacturing, imports, and labeling and promotional practices. We may conduct and participate in clinical studies to obtain marketing clearance, authorization, or certification for new products and new indications for existing products. Unfavorable clinical data from existing or future clinical studies or unfavorable performance evaluations, assessments, and testing may adversely impact our ability to obtain product clearances, authorizations, and certifications, our position in, and share of, the markets in which we participate, and our business, results of operations, financial condition and cash flows. Our facilities and procedures and those of our suppliers are also subject to periodic inspections by the FDA and other governmental and regulatory authorities and to audits by notified bodies to determine compliance with applicable regulations, including quality system regulations for the design, manufacture, packaging, and servicing of med-surg products. In the United States, the results of these inspections can include, and have in the past included, notices of inspectional observations (FDA Form 483s), warning letters, or other forms of enforcement. Our products may also be subject to Import Alerts that restrict the importation of certain of our products or products manufactured by our suppliers into the United States. For example, in January 2024, the FDA issued Import Alerts restricting the importation of plastic syringes manufactured in China by specific suppliers, which impacted our ability to source Medline Brand syringes. In addition, the FDA has taken the position that medical product manufacturers are prohibited from promoting their products other than for the FDA-approved or FDA-cleared indications for use set forth in the product labeling, otherwise known as “off-label use.” A failure to comply with laws, regulations, or guidelines on labeling and promotion could subject us to enforcement actions, significant civil or criminal legal exposure, administrative obligations and costs, untitled letters, warning letters, and other potential penalties from, or agreements with, the federal government and other governmental and regulatory authorities.

If the FDA or other federal, state, local, or foreign governmental or regulatory authorities were to conclude that we are not in compliance with applicable laws or regulations, or that any of our products are ineffective or pose an unreasonable health risk, the FDA or these other authorities could determine such products are adulterated or misbranded, detain or seize such products, order a recall, repair, replacement, or refund of such products, refuse to grant pending applications for clearance, authorization, or certification, require certificates of non-U.S. governments for exports, require corrective actions, seek an injunction, and/or require us to notify

40

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

health professionals and others that the products present unreasonable risks of substantial harm to the public health, and in certain rare circumstances, ban such products. The FDA and other governmental or regulatory authorities may also take other actions, including assessing civil or criminal penalties against us, our officers, or our employees and imposing operating restrictions on a company-wide basis. The FDA may also recommend prosecution to the DOJ. In the European Union (“EU”), penalties for regulatory non-compliance could also be severe, including fines, revocation or suspension of a company’s products or quality management system certificates, and criminal sanctions. Any adverse regulatory or other action, including any adverse press releases or other communications from regulators, depending on its magnitude, may require termination of distribution, impose operating restrictions, result in shutdowns or delays in the introduction of products into the market, restrict us from effectively marketing, shipping, and selling our products, and limit our ability to obtain future clearances, authorizations or certifications, licenses, registrations, or permits, and could result in a substantial modification to our business practices and operations. Such actions could result in restrictions on our ability to carry on or expand our operations and higher than anticipated costs or lower than anticipated sales. In addition, our inability to address noncompliance issues raised by the FDA and other governmental or regulatory authorities or notified bodies in an effective and timely manner may also cause negative publicity and a loss of customer confidence in us or our current or future products, which may result in the loss of sales and difficulty in successfully launching new products.

Furthermore, we occasionally receive subpoenas or other requests for information from state and federal governmental authorities, which primarily relate to financial arrangements with healthcare professionals, regulatory compliance, and product promotional practices. These investigations may require us to expend extensive resources or time to respond. Any adverse outcome in one or more of these investigations could result in civil and/or criminal proceedings, substantial fines, penalties, and/or administrative remedies, including exclusion from government reimbursement programs, debarment, and/or entry into corporate integrity agreements with governmental authorities. In addition, resolution of any of these matters could involve the imposition of additional, costly compliance obligations. These potential consequences could have a material adverse effect on our business, results of operations, and financial condition.

Finally, we also have contracts with government entities, which are subject to risks such as lack of funding, a government’s refusal to make payments, and complex legal compliance requirements. For example, government contract purchase obligations are typically subject to the availability of government funding, which may be eliminated, and governments may also refuse to meet purchase obligations. Our government contracts might not be renewed or might be terminated for convenience by the government with little or no prior notice, which could have a material adverse effect on our business, results of operations, and financial condition. Additionally, we have experienced requests under certain customer contracts, including certain government contracts, to require a designated amount of the contract to be fulfilled by underrepresented suppliers for goods and services, including minority-owned, women-owned, veteran-owned, or other diversity suppliers (“Diversity Suppliers”). As a result, we may be required to set aside a portion of spend under our contracts for Diversity Suppliers, which may decrease our net sales under such arrangements. Any required adjustments to our efforts, such as modifications in regard to Diversity Suppliers, could increase operational complexity and legal risk. The U.S. federal government may issue updated guidance, reassess existing supervisory frameworks, or pursue enforcement actions via the False Claims Act or other mechanisms or targeted executive enforcement actions based on perceived violations of revised standards. At the same time, some states continue to require affirmative action policies or corporate diversity reporting, adding further complexity. We have also experienced requests under certain commercial and government contracts for conditions related to sustainability or similar requirements, such as information on ethical sourcing or access to our suppliers for social audits, the implementation of environmentally preferable purchasing programs, or product-end-of-life and product circularity. These requirements may lead to increased compliance costs and impact our ability to renew such contracts.

We are subject to extensive environmental, health, and safety requirements, and our operations involve hazardous and other environmentally sensitive substances.

We are subject to extensive federal, state, provincial, local, and international environmental, health, and safety requirements concerning, among other things, the health and safety of our employees, the generation, disposal, storage, registration, labeling, reporting, use, and transportation of hazardous and other environmentally sensitive substances (including per- and polyfluoroalkyl substances, or “PFAS”), consumer products, emissions or discharges of substances into the environment, investigation and remediation of contamination at various sites, and chemical constituents (including PFAS) in products. Our suppliers are also subject to such requirements, and any failure by, or inability of, our suppliers to comply with such requirements could result in shortages of products or capacity that could impact our operations.

New environmental, health, and safety laws and regulations, violations of these laws or regulations, stricter enforcement of existing requirements, or the discovery of previously unknown contamination could result in increased costs and other burdens. For example, we and other medical product manufacturers use EtO to sterilize certain medical products we manufacture or distribute. EtO has been the subject of increasing public and regulatory scrutiny because of changes in the assessment of health risks related to EtO emissions. We have made substantial capital expenditures to upgrade emissions controls at certain of our facilities where we expect to continue using EtO. If regulatory measures become more stringent or widespread, we could experience increased costs to comply with more stringent emissions standards, and we and other industry participants may be unable to effectively sterilize medical products, possibly resulting in supply shortages or an industry-wide reduction in surgical or medical procedures, which would negatively impact demand for our products. Likewise, the presence of PFAS in products is also an emerging area of focus by regulators and the public, and we have implemented procedures to comply with evolving regulatory requirements.

In addition, certain environmental laws assess liability on current or previous owners or operators of real property or those who have arranged for the disposal or treatment of hazardous and other environmentally sensitive substances for the costs of investigation, removal, or remediation of those substances at their properties or at other locations where those substances have been sent for treatment or disposal. This liability may be imposed regardless of fault, and in many situations may be joint and several, meaning that a liable entity may be held responsible for more than its share of the liability, potentially up to the entire liability, if other responsible entities cannot be found or are unable to respond. In addition to cleanup actions brought by governmental authorities, private parties could bring personal injury or other claims due to the presence of, or exposure to, hazardous substances and other environmentally sensitive materials. The ultimate cost of site cleanup and timing of future cash outflows is difficult to predict, given the uncertainties regarding the extent of the required cleanup and the interpretation of applicable requirements.

Our cost of complying with current or future environmental, health and safety requirements, and obligations to investigate and/or remediate environmental conditions currently known or as may be identified or arise in the future and/or to address claims resulting from such conditions, may require material expenditures by us, exceed our estimates, or have a material adverse effect on our business, results of operations, and financial condition.

The failure to comply with anti-corruption laws or trade restrictions, including economic sanctions, could materially adversely affect our business, results of operations, and financial condition and result in civil and/or criminal penalties.

We are subject to applicable anti-corruption, anti-bribery, and similar laws, such as the FCPA, the U.S. domestic bribery statute in 18 U.S.C. § 201, and similar laws in other jurisdictions in which we operate. Anti-corruption laws generally prohibit companies and intermediaries from corruptly promising, authorizing, making, offering, or providing anything of value to a foreign government official or, in certain instances, commercial counterparties, for the purpose of obtaining or retaining business. These laws may also require companies to implement adequate internal controls, procedures, and certain books and records standards and controls. Our

42

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

international operations create a risk of unauthorized payments or offers of payments by one of our employees, consultants, sales agents, distributors, channel partners, or other third parties acting on our behalf. Because of the predominance of government-administered healthcare systems in many jurisdictions around the world, many of our customer relationships outside of the United States involve governmental entities, which increases risks under the FCPA and other anti-corruption laws. We also participate in public-private partnerships and other commercial and policy arrangements with governments around the globe, which could be subject to these laws and similarly increase risks under the FCPA and other anti-corruption laws. Global enforcement of anti-corruption laws has increased in recent years, including investigations and enforcement proceedings leading to assessment of significant fines, penalties, and other sanctions against companies and individuals.

Further, we are subject to laws and regulations, including governmental export and import controls, that could subject us to liability. Our products are subject to export controls of the jurisdictions in which we operate, including the U.S. Department of Commerce’s Export Administration Regulations. In addition, various governmental authorities, including the United Nations, the EU, the United Kingdom and the United States (including the Office of Foreign Assets Control within the U.S. Department of the Treasury (“OFAC”)) administer and enforce economic sanctions laws and regulations prohibiting persons subject to their jurisdiction from dealing with countries or territories subject to comprehensive sanctions and with certain other designated individuals and entities (collectively, “Sanctions Targets”). Our international operations may expose us, directly or indirectly, to Sanctions Targets. Any future imposition of sanctions by the United States, the EU or any of its member states, the United Kingdom, or any other sanctions authority relevant to our business may reduce the flow of goods from certain of our suppliers or may prevent us, either legally or practically, from engaging in dealings with certain individuals, countries, or jurisdictions.

Our policies and procedures designed to promote compliance by us and our directors, officers, employees, representatives, consultants, sales agents, distributors, or other third parties with the FCPA, OFAC restrictions, and other applicable laws and regulations related to anti-corruption, economic sanctions, and export controls may not always be effective, and our employees, representatives, consultants, sales agents, or distributors may engage in conduct for which we could be held responsible. Any alleged or actual violations of these laws and regulations may subject us to government scrutiny, significant criminal or civil penalties, or other sanctions and other liabilities, including exclusion from government contracting, as well as related stockholder lawsuits, all of which could disrupt our business, and adversely affect our reputation, business, results of operations, and financial condition.

We are subject to complex and rapidly evolving data privacy, security, and data protection laws and regulations and the costs to comply with such laws and regulations or any ineffective compliance efforts with such laws and regulations may adversely impact our business.

Our business includes the Processing of Personal Data of consumers; Medline applicants, employees, and other workforce members; our customers’ patients, plan members, and employees; our vendors’ employees; and other third parties, as well as PHI, where we meet the definition of a Business Associate (as such term is defined under HIPAA) for certain parts of our business. We maintain PHI that we Processed about Medline’s own patients under certain of our historic offerings. We are directly or, through our customers, indirectly subject to numerous and evolving federal, state, and foreign laws and regulations relating to the Processing of Personal Data and PHI, such as HIPAA, the GDPR, the California Consumer Privacy Act, which was further expanded by the California Privacy Rights Act of 2020 (“CPRA” and collectively, “CCPA”), and similar data privacy legislation enacted or under consideration by various other U.S. states. Laws and regulations relating to privacy and data protection are continually evolving and subject to potentially differing interpretations and levels of enforcement by various courts and regulators, including in connection with changes in governmental administrations. Compliance with all current and emerging privacy, security and data protection laws, regulations, and requirements, as well as laws that are adjacent (such as the proliferation of new laws and regulations addressing generative AI) to those domains is increasingly difficult.

In the United States, the Federal Trade Commission (the “FTC”) is increasingly active in regulating health-related privacy and security. The FTC has taken enforcement actions against companies for statements or

43

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

promises made about the privacy or security of health information, through Section 5 of the Federal Trade Commission Act (the “FTCA”), which prohibits unfair or deceptive acts or practices, as well as through the Health Breach Notification Rule (“HBNR”), which applies to certain “personal health record-related entities” or “third party service providers.” We may also be subject to scrutiny by federal and state regulators, partners, and consumers related to our collection, use, and disclosure of consumer Personal Data, including health information. Additionally, federal and state consumer protection laws continue to be applied by FTC and states’ Attorneys General to regulate the collection, use, storage, and disclosure of Personal Data.

In January 2025, the DOJ issued final regulations on bulk U.S. sensitive personal data and government-related data that prohibit or restrict U.S. persons from knowingly directing or engaging in defined classes of transactions that allow persons in “countries of concern” (China, including Hong Kong and Macau, Russia, Iran, North Korea, Cuba, and Venezuela) or those otherwise deemed a “covered person” access to bulk U.S. sensitive personal data and U.S. government-related data. Violations of the regulations can result in civil and criminal penalties. The regulations may further complicate compliance efforts and increase legal risk and compliance costs for us and the third parties upon whom we rely.

At the state level in the United States, the CCPA added new privacy protections for California residents with respect to certain types of Personal Data, including by introducing new data privacy rights for California residents and establishing a regulatory agency dedicated to enforcing compliance. Various other U.S. states have enacted similar comprehensive consumer data privacy legislation, and several other U.S. states are considering expanding or passing privacy laws in the near term. Further, states such as Washington, Connecticut, and Nevada have recently enacted broadly applicable laws to protect the privacy of personal health information, which generally require regulated entities to obtain consent for the collection, use, or sharing of any “consumer health data,” which may include Personal Data that is linked or reasonably linkable to a consumer and that identifies a consumer’s past, present, or future physical or mental health. The effects of such state privacy laws are potentially far-reaching and may require us to modify our data Processing practices and policies and incur substantial compliance-related costs and expenses, and it remains unclear how various provisions will be interpreted and enforced by the courts and regulators.

Similarly, many foreign laws and regulations, including in countries in which we currently operate, govern the Processing of Personal Data. For example, the GDPR imposes requirements for controllers and processors subject to the law with respect to Processing the Personal Data of EU and UK residents. Non-compliance with the GDPR can result in substantial fines and other penalties, required changes to our business practices and reputational harm, any of which could have an adverse effect on our business.

In the event of a privacy or security incident or claim that we, a service provider, a third party with which we do business, or a hacker or other third party with authorized or unauthorized access to our data has violated applicable privacy or security laws and regulations, we may be subject to regulatory or legal action. A data breach or any allegations of a failure to comply with such privacy or security laws by us or our service providers or other third parties working on our behalf could result in reputational damage, adverse publicity, loss of consumer confidence, reduced sales and profits, complications in executing our growth initiatives, and regulatory and legal risk, including enforcement actions, regulatory investigations, fines and penalties, and in some cases, civil liabilities where individuals have been provided with a private right of action, all of which could materially and adversely affect the results of our operations, financial performance, and business, as well as have a negative impact on business reputation and performance. In addition, we could be required to modify our activities, processes, solutions and services as a result of any enforcement actions or remediation efforts, which could have an adverse effect on our business, results of operations or financial condition. If laws or regulations are changed or expanded, or if governing jurisdictions interpret or implement laws or regulations in new ways it could require changes in our business practices and adversely affect our business, financial condition and results of operations.

Our use or our third-party service providers’ or business partners’ use of AI, automated decision-making and machine learning technologies and the evolving regulatory framework in this area may subject us to risks or heightened costs that could adversely affect business, results of operation and financial condition.

We use Machine Learning Technology in connection with our business activities to realize operating efficiencies. Notwithstanding our policies and related personnel training governing use of Machine Learning Technology, our personnel, affiliates, or other third parties working with us or on our behalf could utilize Machine Learning Technology in contravention of such policies, including in ways that could subject us to potential liabilities. We could be further exposed to the risks of Machine Learning Technology if third-party service providers or any other counterparties with whom we interact, whether or not known to us, also use Machine Learning Technology in their business activities. Machine Learning Technology and its current and potential future applications, as well as the legal and regulatory frameworks within which it operates, continue to rapidly evolve. As such, it is not possible to predict the full extent of the current or future risks related to Machine Learning Technology. Independent of its context of use, Machine Learning Technology is generally highly reliant on the collection and analysis of large amounts of data, and it is not possible or practicable to incorporate all relevant data into the model that Machine Learning Technology utilizes to operate. Certain data in such models will inevitably contain or result in a degree of bias, inaccuracy and error—potentially materially so—and could otherwise be inadequate or flawed, which would be likely to degrade the effectiveness of Machine Learning Technology and the reliability and accuracy of its output. To the extent that we rely on or use the output of Machine Learning Technology, any such inaccuracies, biases or errors could have adverse impacts on us, our business, our results of operations or financial condition. Additionally, the volume of and reliance on data and algorithms also make Machine Learning Technology, and in turn us, more susceptible to cybersecurity threats.

We could be exposed to risks to the extent third-party service providers or any counterparties use Machine Learning Technology in their business activities, notwithstanding any preventative policies aimed at restricting or governing the use of such technologies. We are not able to control the way third-party products are developed, trained or maintained or the way third-party services utilizing Machine Learning Technology are provided to us. Use of Machine Learning Technology could include the input of our confidential information (including confidential information and Personal Data) by third parties in contravention of non-disclosure agreements or by our personnel or other related parties in contravention of our policies and procedures and, in each case, could result in such confidential or personal information becoming part of a dataset that is generally accessible by Machine Learning Technology applications and users. The misuse or misappropriation of our data or information of our customers could have an adverse impact on our reputation and could subject us to legal and regulatory investigations and/or actions.

Moreover, some customers may impose their own restrictions on our use of Machine Learning Technology in our performance of services under a contract. While we generally resist any broad restrictions by customers related to our use of Machine Learning Technology, we may be subject to certain restrictions that could create redundancies in systems that omit Machine Learning Technology, which may be costly and inefficient.

In recent years, the use of Machine Learning Technology has come under increased regulatory scrutiny, especially in the case of generative AI and related developments, due to the potential harm to individuals where Personal Data or intellectual property is processed or where models are trained on vast data sets that include Personal Data or intellectual property. The Biden administration took several actions related to Machine Learning Technology, some of which have since been overturned by the Trump administration. One example of FDA actions related to AI is the FDA’s January 2025 draft guidance document “Artificial Intelligence-Enabled Device Software Functions: Lifestyle Management and Marketing Submission Recommendations.” Various U.S. states are in the process of enacting (or have already enacted) new laws and regulations that are aimed at providing individuals with additional protections in connection with Machine Learning Technology. It is unclear what, if any, of the current administration’s initiatives related to Machine Learning Technology will be continued, modified, revoked, or replaced by the Trump administration. In addition to the U.S. regulatory framework, the EU has recently

45

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

introduced a new regulation applicable to certain Machine Learning Technology and the data used to train, test and deploy them (the “EU AI Act”). The EU AI Act entered into force on August 1, 2024, with its obligations set to apply in phases from six to 36 months thereafter. The EU AI Act applies on an extraterritorial basis and will impose significant requirements on both the providers and deployers of Machine Learning Technology, with violations punishable by sanctions of up to 7% of annual worldwide revenue or EUR 35 million (whichever is higher) for the most serious breaches. Any actual or perceived failure to comply with evolving regulatory frameworks around the development and use of Machine Learning Technology could adversely affect our business, results of operations and financial condition. New laws, regulations, executive orders, guidance and decisions in this area may limit our ability to use Machine Learning Technology or require us to make changes to our operations that may decrease our operational efficiency, result in an increase to operating costs, and hinder our ability to improve our services.

If tax laws change or we experience adverse outcomes resulting from examination of our tax returns or disagreements with taxing authorities, it could adversely affect our business, financial condition, and results of operations.

We are subject to tax in the United States and in certain foreign jurisdictions in which we operate. The United States and many countries in Europe, as well as a number of other countries and organizations, have recently proposed or recommended changes to existing tax laws or have enacted new laws that could significantly increase our tax obligations in many countries where we do business, or require us to change the manner in which we operate our business. For example, in August 2022, the Inflation Reduction Act (the “IRA”) was signed into law. The IRA, among other things, includes a new 15% corporate minimum tax as well as a 1% excise tax on corporate stock repurchases, subject to certain exceptions. In addition, in July 2025, the One Big Beautiful Bill Act (the “OBBBA”) was signed into law. The OBBBA introduced significant changes to numerous areas of U.S. federal income tax law, including permanency of certain provisions in the 2017 Tax Cuts and Jobs Act, and changes to R&D expensing, bonus depreciation, and international tax provisions. Other developments include certain proposals by the Organization for Economic Co-operation and Development arising from its Base Erosion and Profit Shifting project and the implementation of the global minimum tax under the Pillar Two model rules. The application and interpretation of these laws in different jurisdictions affect our operations in complex ways and are subject to change, and some changes may be retroactively applied. Additional guidance with respect to any of these rules or other changes in tax law could materially affect our financial position, tax obligations, and effective tax rate.

In addition, we are subject to the examination of our income and other tax returns by the United States Internal Revenue Service (the “IRS”) and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of our provision for income taxes. Although we believe we have made appropriate provisions for taxes in the jurisdictions in which we operate, changes in the tax laws or challenges from tax authorities under existing tax laws could adversely affect our business, financial condition, and results of operations.

We may become subject to litigation brought by third parties claiming infringement, misappropriation, or other violation by us of their intellectual property rights.

Our commercial success depends in part on avoiding infringement, misappropriation, or other violations of the intellectual property of third parties. However, we cannot be certain that our products and technologies and the conduct of our business does not and will not infringe, misappropriate, or otherwise violate the intellectual property rights of others or be alleged to do same. Any claim that we, or consultants, customers or other third parties retained or indemnified by us, have violated the intellectual property of third parties, with or without merit, and whether or not it results in litigation, is settled out of court or is determined in our favor, could be time consuming and costly to address and resolve, and could divert the time and attention of management and technical personnel from our business. Our liability insurance may not cover potential claims of this type adequately or at all. We also may have to seek third-party licenses to intellectual property, which may be unavailable, require payment of significant royalties, or be available only at commercially unreasonable, unfavorable, or otherwise unacceptable terms. In the event of a settlement or adverse judgment, our results of

46

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

operations may materially decline if we are prohibited from using intellectual property that is material to the operation of our business. Even in instances where we believe that claims and allegations of intellectual property infringement against us are without merit, defending against such claims may be time consuming and expensive and may result in the diversion of time and attention of our management and employees. Any of these events could have a material adverse effect on our business, results of operations, and financial condition.

Climate change or legal, regulatory or market measures to address climate change may negatively affect our business, results of operations, and financial condition.

The physical impacts of climate change, including increased frequency and severity of natural disasters, sea levels rising, and extreme temperatures, may pose physical risks to our facilities and/or operations, and/or disrupt our supply chain. For example, storm activity in Nuevo Laredo, Mexico in 2021 caused damage to our facilities and temporarily disrupted our operations in the region, and similar climate events could adversely affect our business, results of operations, and financial condition in the future. Our transition risks, which are risks associated with the transition towards a low-carbon economy, may include mass climate-related migration and shifting demand for our products and decreased availability or less favorable pricing for water and other critical raw materials or energy, which could impact our manufacturing and distribution operations and the competitiveness of our products. While shifting needs can create opportunities in new markets or for new products, failure to adapt to these changed circumstances can also pose potential business risks.

Our business could be affected by current and future local, state, federal, and international laws, regulations, treaties, agreements, and policies related to greenhouse gas emissions and climate change. Some existing laws and regulations to reduce greenhouse gas emissions include controls, carbon levies, cap and trade programs and/or other measures, and additional regulation of such emissions is likely. More stringent interpretation of existing laws or regulations, as well as future laws or regulations in response to concerns over climate change, could require us and/or our suppliers to take action to reduce emissions of greenhouse gases or incur costs to obtain allowances or credits for our emissions. As a result, the costs and restrictions associated with sourcing, manufacturing, and distributing our products could significantly increase, which may adversely affect our business, results of operations, and financial condition. Further, the impacts of climate change may influence customer preferences, including driving customers to seek products that are low carbon or have other sustainability characteristics, and failure to provide products that anticipate or adequately respond to these changes in preference could damage our reputation and result in loss of market share.

The increasing focus on ESG and sustainability matters or the failure or perceived failure to meet our ESG and sustainability goals may increase our costs, harm our reputation or adversely affect our business.

Companies are facing increasing scrutiny from investors, customers, patients, consumers, employees, proxy advisory firms, nongovernmental organizations, and other stakeholders related to environmental, social, and governance (“ESG”) matters, including governance practices and with respect to environmental and social sustainability–related efforts and belonging initiatives. We may experience pressure to make commitments relating to ESG matters that affect our business or industry, including strategic risk mitigation initiatives relating to sustainability. Expectations regarding the management of ESG initiatives continue to rapidly evolve. Moreover, in recent years “anti-ESG” and “anti–diversity, equity, and inclusion” sentiments have gained momentum across the United States, with several dozen states, the U.S. Congress, and the U.S. Executive Branch having proposed or enacted “anti-ESG” or “anti–diversity, equity, and inclusion” policies, legislation, executive orders or initiatives, or issued related legal opinions. Further, we may from time to time engage in various efforts, including setting policies and goals or making voluntary or required statements and disclosures. The policies, goals, statements, and disclosures reflect our current circumstances, plans, and aspirations at the time they are made. Our efforts to accomplish and accurately report on our efforts and goals are subject to a number of factors, many of which are outside of our control, including economic conditions, our ability to implement certain types of technology, the costs of implementing aspirational changes, our ability to offer our products and services at competitive market rates to meet customer and consumer expectations, unforeseen operational and implementation challenges, and collaboration with third parties. Our expectations and assumptions are

47

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established, singular approach to identifying, measuring and reporting on many ESG matters. We may also be required to expend significant resources to meet our goals, which could increase our operational costs. We may also determine that it is in the best interest of our Company and our stockholders to prioritize other business, social, governance, or sustainable investments over the achievement of our current goals based on economic, technological developments, regulatory and social factors, business strategy, or pressure from investors, activist groups, or other stakeholders. Additionally, our current ESG practices may not comply with future stakeholder expectations, reporting frameworks, regulatory requirements, or best practices. If we are not effective in addressing ESG matters important to our stakeholders, or setting and meeting relevant ESG goals in a timely manner, our reputation, attractiveness as an investment, business partner, or acquiror, access to and costs of capital, financial results, and stock price may suffer. If our sustainability practices do not meet evolving stakeholders’ expectations and standards, or if we are unable to satisfy all stakeholders, our reputation, ability to attract or retain employees, financial condition, results of operations, and cash flows could be negatively impacted. In addition, even if we are effective at addressing ESG and sustainability matters, we may experience increased costs to execute upon these goals that may not be offset by any benefit to our reputation, which could have an adverse impact on our business and financial condition.

We are involved in legal proceedings and disputes, which could adversely impact our business, results of operations, and financial condition.

We are routinely party to a number of lawsuits, settlement discussions, mediations, arbitrations, demands, investigations, and other disputes, including those related to commercial matters and contracts, personal injury and product liability, state and federal labor and employment (including healthcare benefits and discrimination), healthcare regulation, intellectual property, import and export regulations, environmental matters (such as PFAS purportedly found in products and EtO emissions), tax, real property, privacy, and our trucking operations. These current and future matters require us to dedicate significant internal and external resources and costs to respond and comply, and may result in substantial monetary damages or penalties; harm our reputation; require us to pay additional wages, insurance expenses, and payroll-related taxes or sizeable statutory penalties; cause us to lose patent protection or tax benefits; require us to revise or restate our financial statements; divert our management’s time, attention, and resources; or otherwise adversely affect our sales and business. In addition, we may be required to redesign, re-label, restrict, or recall products; cease manufacturing and selling products; comply with a court injunction restricting or prohibiting further marketing and sale of products or services; or comply with a consent decree, which could result in further regulatory constraints, or we may be subject to the seizure of our product inventory or determine that certain products in our inventory should no longer be shipped as a result of regulatory requests or actions or safety or other issues. Even claims without merit could subject us to adverse publicity, harm our reputation, require us to incur significant legal fees, or cause us to modify our pay or other practices. Any of these events could have a material adverse effect on our business, results of operations, financial condition, cash flows, and profitability. In addition, even if we believe we have meritorious defenses, from time to time we may engage in settlement discussions and mediation. In considering settlements, we take into account various factors, including developments in pending legal proceedings and the related risks and uncertainties.

The reserves we establish for estimated losses with respect to these matters represent our estimate of the probable loss at the time the reserve is established, to the extent future losses are probable and reasonably estimable. This involves judgment and may not reflect the full range of uncertainties and unpredictable outcomes. Additional reserves may be established or current reserves may be significantly increased from time to time. Until the final resolution of a matter, we may be exposed to losses in excess of the amount recorded, and such amounts could be material. In addition, any settlements we enter may be confidential and could be significant and result in charges in excess of accruals. If any of our estimates and assumptions change or prove to have been incorrect, it could have a material effect on our business, consolidated financial position, results of operations, or cash flows.

Our failure to comply with laws and regulations relating to reimbursement of healthcare goods and services may subject us to penalties and adversely impact our reputation, business, results of operations, financial condition, and cash flows.

The ability of our customers to obtain appropriate reimbursement for products and services from third-party payers is critical because it affects which products customers purchase and the prices they are willing to pay. Our products are purchased principally by hospitals or healthcare professionals that typically seek reimbursement from various third-party payers, such as governmental healthcare programs (e.g., Medicare, Medicaid, TRICARE, and comparable non-U.S. programs), private insurance plans, and managed care plans for the healthcare services provided to their patients. As a result, our products are subject to laws and regulations enforced by governmental and regulatory authorities, including HHS, CMS, the DOJ, and state and non-U.S. agencies responsible for reimbursement and regulation of healthcare goods and services. These laws and regulations address fair competition, kickbacks, false claims, self-referrals, and healthcare fraud and abuse (e.g., the federal False Claims Act (“FCA”), Physician Self-Referral Law (the “Stark Law”), Anti-Kickback Statute (“AKS”), the Civil Monetary Penalties Statute, HIPAA, and the Physician Payments Sunshine Act). See “Business—Government Regulation—Healthcare Fraud and Abuse Laws and Regulations.” Many jurisdictions have similar laws that apply to reimbursement by state Medicaid or other funded programs and all payers, and require transparency in interactions with and payments, or other transfers of value, to healthcare professionals.

The relationships that we, and third parties that market and/or sell our products, have with healthcare facilities and professionals are subject to scrutiny under these and other federal, state, and foreign laws. For example, we are engaged in giving discounts within the meaning of the AKS, which prohibits knowingly and willfully offering, paying, soliciting, or receiving any remuneration to induce or reward, or in return for the referral of an individual for, or the purchasing, ordering, or recommending of items or services, for which payment may be made in whole or in part by Medicare, Medicaid, or other federally funded healthcare programs. Under the AKS, there are exceptions for, among other things, properly reported discounts which includes the payment of rebates, and payments of certain administrative fees to GPOs. AKS regulations contain enumerated safe harbors that implement and further refine the statutory exceptions for discounts and payments to GPOs. Engaging in a business practice for which there is an AKS safe harbor may be regarded as suspect if the practice fails to meet each of the prescribed criteria of the appropriate safe harbor, even if such arrangement is lawful. Such arrangements may be subject to greater scrutiny by enforcement agencies.

We maintain internal policies, procedures, training, and monitoring to help ensure our arrangements comply with applicable fraud and abuse laws and other laws and regulations relating to reimbursement of healthcare goods and services. However, governmental officials responsible for enforcing these laws or whistleblowers may assert that we are in violation of them. If our operations are found to be in violation of any such requirements, we may be subject to significant penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, the curtailment or restructuring of our operations, loss of eligibility to obtain approvals from the FDA, exclusion from participation in government contracting, healthcare reimbursement, or other government programs, including Medicare, Medicaid, and TRICARE, integrity oversight and reporting obligations, or reputational harm, any of which could adversely affect our financial results. In certain circumstances, insurance companies may also attempt to bring a private cause of action against us for causing the submission of false claims. Any action against us for an alleged or suspected violation could cause us to incur significant legal expenses and could divert our management’s attention from the operation of our business, even if our defense is successful. In addition, achieving and sustaining compliance with applicable laws and regulations may be costly to us in terms of money, time, and resources.

We are also subject to risks relating to changes in government and private healthcare reimbursement programs and policies, and changes in legal and regulatory requirements in the United States and around the world. Implementation of further legislative or administrative reforms to these reimbursement systems, adverse judicial decisions related to these reimbursement systems, or adverse decisions relating to coverage of or reimbursement for our products by administrators of these systems could have an impact on the acceptance of and demand for our products and the prices that our customers are willing to pay for them.

49

Additionally, we also directly submitted claims to governmental healthcare programs as a Medicare-enrolled durable medical equipment, prosthetics, orthotics, and supplies (“DMEPOS”) supplier. As a result, we have been and from time to time are subject to audits by government healthcare programs and third-party payers related to such claims, which may require refunds of overpayments and may result in penalties, litigation, or enforcement actions. Although we divested the assets associated with this DMEPOS supplier business unit in October 2023, we may nonetheless be subject to past and future product liability claims, enforcement actions, regulatory investigations, fines and penalties, regardless of their ultimate outcome, any of which could harm our reputation and have a material adverse effect on our business, results of operations, and financial condition.

Our insurance program may not cover claims brought against us, deny coverage of claims, or be inadequate to cover future losses.

We maintain third-party insurance to cover our exposure to certain property and casualty losses and are self-insured for certain retentions, claims, and expenses related to other property and casualty losses, including product liability, environmental, and cybersecurity and data privacy losses. Settlement or judgements of claims brought against us may not be covered by insurance or, if covered, our claim may be denied or subject to insurance coverage limits provided by third-party insurers that are insufficient to fully cover unanticipated losses. We are actively pursuing litigation with our excess insurance carriers related to their obligations to reimburse such payments, but we may not be able to obtain reimbursements sufficient to cover our settlement obligations. For example, in connection with the settlement of tort lawsuits related to emissions of EtO from our facility in Waukegan, Illinois, our excess insurance carriers have denied coverage with respect to our settlement payments. As a result of various litigation matters, we recognized $2.0 million of net litigation charges for the year ended December 31, 2024. See “—We are involved in legal proceedings and disputes, which could adversely impact our business, results of operations, and financial condition” and “Note 12—Commitments and Contingencies” of our audited consolidated financial statements and “Note 9—Commitments and Contingencies” of our unaudited condensed consolidated financial statements, each of which is included elsewhere in this prospectus.

Litigation brought against us, regardless of its merits, could be costly to defend and could result in increases of our insurance premiums and exhaust any insurance coverage that we may have. The financial impact of such litigation is difficult to assess or quantify but could adversely affect our business, results of operations, and financial condition. Even where the claim should be covered by insurance, we have significant self-insured retention amounts, which we would have to pay in full before obtaining any insurance proceeds. Product liability insurance for these types of claims is becoming more limited and may not be available to us at amounts that we historically have obtained or that we would like to obtain.

Any failure to obtain, maintain, protect and enforce our intellectual property rights, or the failure of the strength or scope of our intellectual property rights, could harm our business, financial condition, and results of operations.

We rely on a combination of patents, trademarks for our material brands (e.g., Medline, Curad, Microtek, Hudson, and Proxima), copyrights, trade secrets, and other intellectual property rights in the United States and other countries, as well as agreements (such as employee, customer, non-disclosure, and non-competition agreements) to protect our intellectual property and proprietary rights. We may, over time, increase our investment in formal registrations for additional intellectual property, including through additional patent and trademark and registrations. Effective intellectual property protection is expensive to develop and maintain, both in terms of initial registration and ongoing renewal and maintenance requirements and the costs of defending and asserting our rights.

Others may infringe our trademarks or other intellectual property, independently develop similar manufacturing processes and technology, duplicate any of our manufacturing processes, technology or services, or design around our intellectual property to avoid any infringement. The measures we take to obtain, maintain, protect, and enforce our intellectual property, including litigation, could cause us to expend significant cost and time, may distract management and may not be sufficient to detect, prevent, or enforce infringement, misappropriation, or other violation. Effective intellectual property protection may not be available in every

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

country in which we offer our products and services now or in the future or may not protect them to the same extent as the laws of the United States. Any changes in, or unexpected court interpretations of, intellectual property laws may compromise our ability to enforce our patent, trademark, trade secret, and other intellectual property rights. Further, our intellectual property rights may be challenged, or our efforts to enforce them may be met with defenses, counterclaims and countersuits attacking their validity and enforceability that, if successful, could weaken, invalidate, or render them unenforceable.

If we are unable to protect our intellectual property, particularly our patents, brands, and know-how, our intellectual property may be impaired, we may lose a portion of our intellection property and our image, brand, competitive position, and business could be harmed. Moreover, our failure to develop and properly manage new intellectual property could hurt our market position and business opportunities. All of these could have a material adverse effect on our business, financial condition, and results of operations.

Risks Related to Financial and Economic Market Conditions

Foreign currency exchange rate fluctuations could have a significant impact on our results of operations.

We operate in various international markets, including Canada, Mexico, Europe, and the Asia Pacific region, with more significant manufacturing operations in Mexico. For the year ended December 31, 2024, 6.7% of our total net sales and 8.7% of our total expenses related to operations were in currencies other than U.S. dollars, with the majority of our international spend exposed to the euro, Canadian dollar, and Mexican peso. The results of operations of, and certain of our intercompany balances associated with, our international service offerings are exposed to foreign currency exchange rate fluctuations. Upon translation into U.S. dollars, our results of operations may differ materially from expectations, and we may record significant gains or losses on the remeasurement of intercompany balances. As we have expanded our international operations, our exposure to foreign currency exchange rate fluctuations has increased. We hold cash equivalents and marketable securities in foreign currencies including the pound and euros. If the U.S. dollar strengthens compared to these currencies, our cash equivalents and marketable securities balances, when translated, may be materially less than expected and vice versa. Furthermore, we purchase certain of these commodities in currencies other than U.S. dollars and fluctuations in the exchange rate between those currencies and the U.S. dollar may increase our costs. We are also subject to risks due to fluctuations in foreign exchange rates on certain supplies and raw materials that we purchase when negotiating contract renewals. We do not currently have in place any foreign currency exchange rate hedges, and fluctuations in foreign currency exchange rates could have a significant impact on our results of operations.

Our profitability and cash flows may be adversely affected by inflationary pressures.

Inflation has had, and may continue to have, a material impact on the cost to source materials or produce and distribute finished goods to customers. We may not be able to pass these elevated costs on to customers due to contractual or regulatory limits on pricing or customer pressure to reduce costs. To the extent we are able to take pricing actions, there may be a difference between the timing of when we take such actions and the impact of those actions on our results of operations. Additionally, the pricing actions we take may negatively impact our market share. Our failure to effectively assess, timely change and properly set pricing, make price adjustments, or impose surcharges may negatively impact our ability to achieve our pricing objectives. For example, in 2022, we experienced a significant increase in the cost of raw materials and components used to manufacture our products and in the cost of products manufactured by third parties. While certain of these cost increases were passed on to customers, we were required to absorb a large portion of the cost increases due to the existing pricing arrangements. In the event the increase in our costs outpaces the compensating rate increases we may receive, or if we are unable to pass on all or part of our cost increases to our customers through price adjustments and/or surcharges, our profitability and cash flows may be adversely affected.

Uncertain global and domestic macro-economic and political conditions could materially adversely affect our business, results of operations, and financial condition.

Uncertain global and domestic macro-economic and political conditions that affect the economy and the economic outlook of the United States, Europe, Asia and other parts of the world where we do business or source

raw materials could materially adversely affect our business, results of operations, and financial condition. These uncertainties, include, among other things:

The U.S. government has implemented or announced significant new tariffs on products manufactured in a wide range of countries outside the United States, including China, Mexico, and countries in Southeast Asia. These actions have prompted a cycle of retaliatory tariffs and potential retaliatory tariffs by a number of these countries and the United States. While certain of these announced tariffs have been delayed, a number of new tariffs remain in effect, and the U.S. government may in the future impose, reimpose, increase, or pause tariffs, and countries subject to such tariffs have imposed, and in the future may impose, reciprocal tariffs or other protectionist or retaliatory trade measures in response. The imposition of tariffs and other trade restrictions, as well as the escalation of trade disputes and any resulting downturns in the global economy, could materially and adversely affect our business, financial condition, and results of operations. The extent and duration of the tariffs and other trade restrictions and the resulting impact on general economic conditions and on our business are uncertain and depend on various factors, such as negotiations involving the United States and other countries, the responses of other countries or regions, exemptions or exclusions that may be granted, availability and cost of alternative sources of supply, and demand for our products in affected markets. Furthermore, actions we take to adapt to new tariffs or other trade restrictions may cause us to modify our operations, which could be time-consuming and expensive; impact pricing of our products, which could impact our sales and profitability; or cause us to forgo business opportunities.

Global geopolitical conflicts, including the ongoing wars in Ukraine and the Middle East, could lead to significant economic downturns and market and other disruptions, including volatility in the capital markets,

52

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

economic instability, increases in inflation, increased fuel prices, supply chain constraints and disruptions, political and social instability, and economic sanctions, all of which may adversely impact us and the healthcare industry as a whole, particularly if the conflicts occur in areas in which we have a significant concentration of suppliers or customers.

Additionally, changes in government, government debt, and/or budget crises may lead to reductions in government spending in certain countries, which could reduce overall healthcare spending, and/or higher income or corporate taxes, which could depress spending overall. Recessionary or inflationary conditions and depressed levels of consumer and commercial spending may also cause customers to reduce, modify, delay, or cancel plans to purchase our products and may cause suppliers to reduce their output or change their terms of sale. Additionally, if customers’ cash flow or operating and financial performance deteriorate, or if they are unable to make scheduled payments or obtain credit, they may not be able to, or may delay, payment to us. Likewise, for similar reasons suppliers may restrict credit or impose different payment terms.

Our manufacturing business is exposed to price fluctuations of key commodities, which may negatively impact our results of operations and cash flows.

Our manufacturing business relies on product inputs, such as oil-based resins, pulp, cotton, nitrile, and vinyl, as well as other commodities, in the manufacture of its products. Prices of these commodities are volatile and have fluctuated in recent years, which may contribute to fluctuations in our results of operations. We do not currently engage in any hedging activities with respect to commodities. Prices of oil and gas also affect our distribution and transportation costs. Furthermore, due to competitive dynamics and contractual limitations, we may be unable to pass along commodity-driven cost increases through higher prices. If we cannot fully offset cost increases through other cost reductions, or recover these costs through price increases or surcharges, we could experience lower margins and profitability, which could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

Risks Related to Our Indebtedness

Our substantial indebtedness could adversely affect our financial condition, our ability to operate our business or react to changes in the economy or our industry, prevent us from fulfilling our obligations under our debts, and divert our cash flow from operations for debt payments.

We have a substantial amount of debt and are permitted to incur a substantial amount of additional indebtedness, including secured debt, to finance working capital, capital expenditures, investments, or acquisitions, or for other purposes. See “Description of Certain Indebtedness.” Our existing debt could have important consequences, the risks of which may increase if we incur any additional debt, including:

53

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

We are a holding company, and our consolidated assets are owned by, and our business is conducted through, our subsidiaries. Revenue from these subsidiaries is our primary source of funds for debt payments and operating expenses. If our subsidiaries are restricted from making distributions to us, our ability to meet our debt service obligations or otherwise fund our operations may be impaired. Moreover, there may be restrictions on payments by subsidiaries to their parent companies under applicable laws, including laws that require companies to maintain minimum amounts of capital and to make payments to stockholders only from profits. As a result, although a subsidiary of ours may have cash, we may not be able to obtain that cash to satisfy our obligation to service our outstanding debt or fund our operations.

Our ability to make scheduled payments on and refinance our indebtedness is subject to our financial and operating performance, which in turn is affected by general and regional economic, financial, competitive, business, and other factors, all of which are beyond our control, including the availability of financing in the international banking and capital markets. Our business may not generate sufficient cash flow from operations or future borrowings may not be available to us in an amount sufficient to enable us to service our debt, to refinance our debt, or to fund our other liquidity needs. Any refinancing or restructuring of our indebtedness could be at higher interest rates and may require us to comply with more onerous covenants that could further restrict our business operations. Moreover, in the event of a default, the holders of our indebtedness could elect to declare such indebtedness be due and payable and/or elect to exercise other rights, such as the lenders under our Revolving Credit Facility terminating their commitments thereunder and ceasing to make further loans or the lenders under our Senior Secured Credit Facilities instituting foreclosure proceedings against their collateral, any of which could materially adversely affect our results of operations and financial condition.

All of the debt under our Senior Secured Credit Facilities bears interest at variable rates. In recent years, we have experienced higher interest expense on our credit facilities due to interest rate increases, and if interest rates were to increase, our debt service obligations on our credit facilities would further increase, even though the amount borrowed remained the same, especially if our hedging strategies do not effectively mitigate the effects of these increases, and our net income and cash flows, including cash available for servicing our indebtedness, would correspondingly decrease.

Furthermore, we amended the credit agreement governing our Senior Secured Credit Facilities in order to transition our dollar-denominated Senior Secured Credit Facilities to the use of the Secured Overnight Financing Rate (“SOFR”) as a replacement for LIBOR. The composition and characteristics of SOFR are not the same as those of LIBOR. As a result, SOFR or any alternative reference rate may not perform in the same way as LIBOR would have at any time, including, without limitation, as a result of changes in interest and yield rates in the market, market volatility, or global or regional economic, financial, political, regulatory, judicial, or other events. Although SOFR plus a spread adjustment appears to be the preferred replacement rate for U.S. dollar LIBOR, and its use continues to steadily grow, at this time it is not possible to predict the effect of any such changes, any establishment of alternative reference rates, or other reforms to LIBOR that may be enacted in the United States, United Kingdom, or elsewhere. With limited operating history, it remains unknown whether SOFR will continue to evolve and what the effects of its implementation may be on the markets for financial instruments. Disruption in the financial market could have a material adverse effect on our business, financial condition, and results of operations.

The credit agreement that governs the Senior Secured Credit Facilities and the indentures that govern the Senior Notes will each impose significant operating and financial restrictions on our subsidiaries, which may prevent us from capitalizing on business opportunities.

The credit agreement that governs the Senior Secured Credit Facilities and the indentures that govern the Senior Notes each impose significant operating and financial restrictions on our subsidiaries. These restrictions will limit the ability of our subsidiaries to, among other things:

54

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

In addition, if borrowings under our Revolving Credit Facility exceed certain thresholds, our subsidiaries are also subject to a first lien net leverage ratio financial covenant in the credit agreement that governs the Senior Secured Credit Facilities. See “Description of Certain Indebtedness.”

As a result of these restrictions, we will be limited as to how we conduct our business, and we may be unable to raise additional debt or equity financing to compete effectively or to take advantage of new business opportunities. The terms of any future indebtedness we may incur could include more restrictive covenants. We cannot assure you that we will be able to maintain compliance with these covenants in the future and, if we fail to do so, that we will be able to obtain waivers from the lenders and/or amend the covenants.

Our failure to comply with the restrictive covenants described above as well as other terms of our existing indebtedness and any future indebtedness from time to time could result in an event of default, which, if not cured or waived, could result in our being required to repay these borrowings before their due date. If we are forced to refinance these borrowings on less favorable terms or cannot refinance these borrowings, our results of operations, and financial condition could be adversely affected.

Risks Related to Our Organizational Structure

Medline Inc. is a holding company and its only material assets after completion of this offering will be its equity interests held directly or indirectly through wholly owned subsidiaries in Medline Holdings, and it is accordingly dependent upon distributions from Medline Holdings to pay taxes, make payments under the tax receivable agreement, and pay any dividends.

Medline Inc. will be a holding company and after completion of this offering will have no material assets other than its ownership of Common Units held directly or indirectly through wholly owned subsidiaries. Medline Inc. will have no independent means of generating revenue and intends to cause Medline Holdings to make distributions to its holders of Units, including Medline Inc. and the Continuing Unitholders, in an amount sufficient to cover all applicable taxes at assumed tax rates, payments under the tax receivable agreement, and dividends, if any, declared by it. Deterioration in the financial condition, earnings, or cash flow of Medline Holdings and its subsidiaries for any reason could limit or impair their ability to pay such distributions. Additionally, to the extent that Medline Inc. needs funds, and Medline Holdings is restricted from making such distributions under applicable law or regulation or under the terms of its financing arrangements, or is otherwise unable to provide such funds, such restriction could materially adversely affect Medline Inc.’s liquidity and financial condition. There can be no assurance that Medline Holdings will generate sufficient cash flow to distribute funds to us or that applicable state law and contractual restrictions, including negative covenants in any applicable debt instruments, will permit such distributions. Medline Holdings is currently subject to debt instruments or other agreements that restrict its ability to make distributions to us, which may in turn affect Medline Holdings’ ability to pay distributions to us and thereby adversely affect our cash flows.

55

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

Medline Holdings will continue to be treated as a partnership for U.S. federal income tax purposes and, as such, generally will not be subject to any entity-level U.S. federal income tax. Instead, taxable income will be allocated to holders of Units (including Medline Inc.). Accordingly, Medline Inc. will be required to pay income taxes on its allocable share of any net taxable income of Medline Holdings. Liability may be imputed for adjustments to a partnership’s tax return to the partnership itself in certain circumstances, absent an election to the contrary. Medline Holdings may be subject to material liabilities pursuant to this legislation and related guidance if, for example, its calculations of taxable income are incorrect. In addition, the income taxes on Medline Inc.’s allocable share of Medline Holdings’ net taxable income will increase over time as the Continuing Unitholders exchange their Common Units (including Common Units issued upon conversion of vested Incentive Units) for shares of Class A common stock. Such increase in Medline Inc.’s tax expenses may have a material adverse effect on our business, results of operations, and financial condition.

Under the terms of the amended and restated limited partnership agreement, Medline Holdings is obligated to make tax distributions to holders of Units (including Medline Inc.) at certain assumed tax rates. These tax distributions in certain periods are likely to exceed Medline Inc.’s tax liabilities and obligations to make payments under the tax receivable agreement. To the extent that we do not distribute such excess cash as dividends on our Class A common stock or otherwise undertake ameliorative actions between Units and shares of Class A common stock and instead, for example, hold such cash balances, our Continuing Unitholders (other than Medline Inc.) may benefit from any value attributable to such cash balances as a result of their ownership of Class A common stock following a sale or exchange of their Common Units (including Common Units issued upon conversion of vested Incentive Units) for shares of Class A common stock, notwithstanding that such Continuing Unitholders may previously have participated as holders of Units in distributions by Medline Holdings that resulted in such excess cash balances at Medline Inc.

Our board of directors, in its sole discretion, will make any determination from time to time with respect to the use of any such excess cash so accumulated, which may include, among other uses, funding repurchases of Class A common stock; acquiring additional newly issued Common Units from Medline Holdings at a per unit price determined by reference to the market value of the Class A common stock; paying dividends, which may include special dividends, on its Class A common stock; or any combination of the foregoing. Although we expect that our board of directors will take commercially reasonable measures to mitigate such excess cash benefit to the Continuing Unitholders, we will have no obligation to distribute such cash (or other available cash other than any declared dividend) to our stockholders or take any such ameliorative actions. See “Certain Relationships and Related Person Transactions—Medline Holdings Amended and Restated Limited Partnership Agreement.”

Payments of dividends, if any, will be at the discretion of our board of directors after taking into account various factors, including our business, operating results and financial condition, current and anticipated cash needs, plans for expansion and any legal or contractual limitations on our ability to pay dividends. The credit agreement that governs our Senior Secured Credit Facilities and the indentures governing the Senior Notes include, and any financing arrangement that we enter into in the future may include, restrictive covenants that limit our ability to pay dividends. In addition, Medline Holdings is generally prohibited under Delaware law from making a distribution to a partner to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of Medline Holdings (with certain exceptions) exceed the fair value of its assets. Subsidiaries of Medline Holdings are generally subject to similar legal limitations on their ability to make distributions to Medline Holdings.

Our tax receivable agreement confers benefits upon certain of our pre-IPO owners.

Our tax receivable agreement confers benefits upon certain of our pre-IPO owners. Prior to the completion of this offering, Medline Inc. will enter into a tax receivable agreement with certain of its pre-IPO owners that provides for the payment by Medline Inc. to such pre-IPO owners of 90% of certain tax benefits, if any, that Medline Inc. realizes, or is deemed to realize (calculated using certain assumptions), as a result of (i) Medline Inc.’s allocable share of existing tax basis in Medline Holdings’ assets acquired in this offering, (ii) increases in Medline Inc.’s allocable share of existing tax basis and tax basis adjustments to the tangible and intangible assets

56

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

of Medline Holdings as a result of sales or exchanges of Common Units (including Common Units issued upon conversion of vested Incentive Units) in connection with or after this offering, (iii) Medline Inc.’s utilization of certain tax attributes (including any existing tax basis) of the Blocker Companies, which Medline Inc. acquires in connection with this offering, and (iv) certain other tax benefits related to entering into the tax receivable agreement, including tax benefits attributable to payments under the tax receivable agreement. The existing tax basis, increases in existing tax basis, and the tax basis adjustments generated over time may increase (for tax purposes) depreciation and amortization deductions available to Medline Inc. and, therefore, may reduce the amount of tax that Medline Inc. would otherwise be required to pay in the future. It is possible that the IRS may challenge all or part of the validity of such tax basis or other tax attributes covered by the tax receivable agreement, and a court could sustain such a challenge. Actual tax benefits realized by Medline Inc. may differ from tax benefits calculated under the tax receivable agreement as a result of the use of certain assumptions in the tax receivable agreement, including the use of an assumed blended state and local income tax rate of 6% (as adjusted to take into account the U.S. federal tax benefit of such taxes) to calculate tax benefits.

The payment obligation under the tax receivable agreement is an obligation of Medline Inc. and not of Medline Holdings. Payments under the tax receivable agreement are generally due annually five business days following finalization of a schedule showing the relevant tax benefit calculations that is required to be delivered by Medline Inc. within 120 calendar days following the due date (including extensions) of its U.S. corporation income tax return, and interest on such payments will accrue from the due date (without extensions) of such tax return. The term of the tax receivable agreement will continue until all such tax benefits have been utilized or expired. The payments under the tax receivable agreement are not conditioned upon continued ownership of us by the pre-IPO owners. While the amount of existing tax basis and anticipated tax basis adjustments and utilization of tax attributes, as well as the amount and timing of any payments under the tax receivable agreement, will vary depending upon a number of factors, we expect the payments that Medline Inc. may make under the tax receivable agreement will be substantial. Assuming: (i) a price of $   per share of our Class A common stock (based on an assumed initial public offering price of $   per share, the midpoint of the estimated price range set forth on the cover page of this prospectus); (ii) a constant corporate tax rate of  %; (iii) we will have sufficient taxable income to fully utilize the tax benefits; and (iv) no material changes in tax law, if the Continuing Unitholders were to exchange all of the Common Units that they will hold immediately following this offering, and assuming all Incentive Units are converted to Common Units and subsequently exchanged for shares of Class A common stock at an offering price of $  per share of Class A common stock, which is the midpoint of the price range set forth on the cover of this prospectus, we estimate that we would, as a result of the Reorganization Transactions and Offering Transactions and such hypothetical exchange, record a deferred tax asset of approximately $   million and that the aggregate noncurrent liability we would record based on our estimate of the aggregate amount that Medline Inc. would pay under the tax receivable agreement is approximately $   million, generally payable over a 15-year period. For each 5% increase (decrease) in the price per share of our Class A common stock (and therefore the value of the Common Units exchanged), our deferred tax asset would increase (decrease) by approximately $   million and the related liability for payments under the tax receivable agreement would increase (decrease) by approximately $   million. These amounts are estimates and have been prepared for informational purposes only. The actual amount of deferred tax assets and related noncurrent liabilities that we will recognize as a result of any such future exchanges will differ based on, among other things: (i) the amount and timing of future exchanges of Common Units (including Common Units issued upon conversion of vested Incentive Units) by Continuing Unitholders, and the extent to which such exchanges are taxable; (ii) the price per share of our Class A common stock at the time of the exchanges; (iii) the amount and timing of future income against which to offset the tax benefits; and (iv) the tax rates then in effect. See “Certain Relationships and Related Person Transactions—Tax Receivable Agreement.”

In certain cases, payments under the tax receivable agreement may significantly exceed the actual benefits Medline Inc. realizes in respect of the tax attributes subject to the tax receivable agreement.

In the event of certain changes of control, certain material breaches of the tax receivable agreement by Medline Inc., or an insolvency event, the calculation of certain future payments made under the tax receivable

agreement will utilize certain valuation assumptions, including that (i) in the case of a change of control, any Common Units (including Common Units issued or that would have been issued upon conversion of vested Incentive Units) that have not been exchanged are deemed exchanged for the market value of the shares of our Class A common stock at the time of the change of control and (ii) Medline Inc. will have sufficient taxable income to fully utilize (A) the tax attributes covered by the tax receivable agreement and (B) any remaining net operating losses subject to the tax receivable agreement on a straight line basis over the shorter of the statutory expiration period for such net operating losses or the five-year period after the change of control or other relevant event. In addition, recipients of payments under the tax receivable agreement will not be required to reimburse us for any payments previously made under the tax receivable agreement if the tax attributes or Medline Inc.’s utilization of tax attributes underlying the relevant tax receivable agreement payment are successfully challenged by the IRS (although any such detriment would be taken into account as an offset against future payments due to the relevant recipient under the tax receivable agreement). Medline Inc.’s ability to achieve benefits from existing tax basis, tax basis adjustments, or other tax attributes, and the payments to be made under the tax receivable agreement, will depend upon a number of factors, including the timing and amount of our future income. As a result, even in the absence of a change of control, payments under the tax receivable agreement could be in excess of 90% of Medline Inc.’s actual cash tax benefits.

Accordingly, it is possible that the actual cash tax benefits realized by Medline Inc. may be significantly less than the corresponding tax receivable agreement payments. It is also possible that payments under the tax receivable agreement may be made years in advance of the actual realization, if any, of the anticipated future tax benefits. Furthermore, the distribution payments from Medline Holdings may be less than the required payments under the tax receivable agreement and/or Medline Holdings may not have available cash to make its pro rata share of distributions. There may be a material negative effect on our liquidity if the payments under the tax receivable agreement exceed the actual cash tax benefits that Medline Inc. realizes in respect of the tax attributes subject to the tax receivable agreement and/or if distributions to Medline Inc. by Medline Holdings are not sufficient to permit Medline Inc. to make payments under the tax receivable agreement after it has paid taxes and other expenses. We may need to seek to raise additional capital, incur indebtedness, or take other measures to finance payments under the tax receivable agreement to the extent our cash resources are insufficient to meet our obligations under the tax receivable agreement as a result of timing discrepancies, insufficient distributions from Medline Holdings, lack of liquidity in Medline Holdings, or otherwise, and these obligations could have the effect of delaying, deferring, or preventing certain mergers, asset sales, other forms of business combinations, or other changes of control. See “Certain Relationships and Related Person Transactions—Tax Receivable Agreement.”

The application of certain valuation assumptions under the tax receivable agreement in the case of certain changes of control or other events may impair our ability to consummate change of control transactions or negatively impact the value received by owners of our Class A common stock.

In the event of certain changes of control, certain material breaches of the tax receivable agreement by Medline Inc., or an insolvency event, the calculation of certain future payments made under the tax receivable agreement will utilize certain valuation assumptions, including that (i) in the case of a change of control, any Common Units (including Common Units issued or that would have been issued upon conversion of vested Incentive Units) that have not been exchanged are deemed exchanged for the market value of the shares of our Class A common stock at the time of the change of control and (ii) Medline Inc. will have sufficient taxable income to fully utilize (A) the tax attributes covered by the tax receivable agreement and (B) any remaining net operating losses subject to the tax receivable agreement on a straight line basis over the shorter of the statutory expiration period for such net operating losses or the five-year period after the change of control or other relevant event. Such payments may significantly exceed the actual benefits Medline Inc. realizes in respect of the tax attributes subject to the tax receivable agreement. We expect that the payments that we may make under the tax receivable agreement following a change of control will be substantial and may be in excess of 90% of Medline Inc.’s actual cash tax benefits. As a result, the assumptions adopted under the tax receivable agreement in the case of a change of control may impair our ability to consummate change of control transactions or negatively impact the value received by owners of our Class A common stock in a change of control transaction.

Risks Related to this Offering and Ownership of our Class A Common Stock

The Designating Stockholders will continue to hold a significant percentage of our stock, and their interests may conflict with ours or yours in the future.

Immediately following this offering and the application of net proceeds therefrom, the Designating Stockholders will beneficially own or control approximately  % of the combined voting power of our shares eligible to vote in the election of our directors (or  % if the underwriters exercise in full their option to purchase additional shares of Class A common stock). Moreover, we will agree to nominate to our board individuals designated by the Designating Stockholders in accordance with the director nomination agreements we intend to enter into in connection with this offering. The Designating Stockholders will retain the right to designate directors subject to the maintenance of certain ownership requirements in us. See “Certain Relationships and Related Person Transactions—Director Nomination Agreements.” For so long as the Designating Stockholders continue to own a significant percentage of our stock, they will still be able to significantly influence the composition of our board of directors and the approval of actions requiring stockholder approval through their voting power. Accordingly, for such period of time, the Designating Stockholders will have significant influence with respect to our management, business plans, and policies, including the appointment and removal of our officers. In particular, for so long as the Designating Stockholders continue to own a significant percentage of our stock, the Designating Stockholders may be able to prevent a change of control of our company or a change in the composition of our board of directors and could preclude any unsolicited acquisition of our company. The concentration of ownership could deprive you of an opportunity to receive a premium for your shares of Class A common stock as part of a sale of our company and ultimately might affect the market price of our Class A common stock.

In addition, immediately following this offering and the application of the net proceeds therefrom, the Continuing Common Unitholders (which include certain interests held by our Principal Stockholders) will own  % of the Common Units (or  % if the underwriters exercise in full their option to purchase additional shares of Class A common stock). Because they hold their ownership interest in our business directly in Medline Holdings, rather than through Medline Inc., the Continuing Common Unitholders may have conflicting interests with holders of shares of our Class A common stock. For example, if Medline Holdings makes distributions to Medline Inc., the Continuing Common Unitholders and participating Continuing Incentive Unitholders (as described below) will also be entitled to receive such distributions pro rata in accordance with the percentages of their respective Common Units or Incentive Units, as applicable, in Medline Holdings and their preferences as to the timing and amount of any such distributions may differ from those of our public stockholders. Incentive Units initially will not be entitled to receive distributions (other than tax distributions) until holders of Common Units have received a minimum return as provided in the amended and restated limited partnership agreement of Medline Holdings. However, Incentive Units will have the benefit of adjustment provisions that will reduce the participation threshold for distributions in respect of which they do not participate until there is no participation threshold, at and after which time the Incentive Units would participate pro rata with distributions on Common Units. Although our Designating Stockholders are not holders of Incentive Units, our Named Executive Officers will hold a significant amount of Incentive Units which could create conflicts or misalignment of interest with the Continuing Common Unitholders and holders of shares of our Class A common stock. The pre-IPO owners may also have different tax positions from Medline Inc., which could influence their decisions regarding whether and when to dispose of assets, especially in light of the existence of the tax receivable agreement that we will enter into in connection with this offering, and whether and when to incur new or refinance existing indebtedness. In addition, the structuring of future transactions may take into consideration our pre-IPO owners’ tax or other considerations even where no similar benefit would accrue to us. See “Certain Relationships and Related Person Transactions—Tax Receivable Agreement.”

Our amended and restated certificate of incorporation will not limit the ability of our Sponsors, the Mills Family, and our Other Pre-IPO Investors to compete with us, and they may have investments in businesses whose interests conflict with ours.

Our Sponsors, the Mills Family, our Other Pre-IPO Investors, and their respective affiliates engage in a broad spectrum of activities, including investments in businesses that may compete with us. In the ordinary

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

course of their business activities, our Sponsors, the Mills Family, our Other Pre-IPO Investors, and their respective affiliates may engage in activities where their interests conflict with our interests or those of our stockholders. Our amended and restated certificate of incorporation provides that we will renounce any interest or expectancy that we would otherwise have in, and the right to be offered to participate in, any business opportunity that from time to time may be presented to our Sponsors, our Other Pre-IPO Investors, the Mills Family, subject to limited exceptions, or any of their respective affiliates or any of our directors who are not employed by us (including any non-employee director who serves as one of our officers in both their director and officer capacities) or their affiliates. See “Description of Capital Stock—Conflicts of Interest.” Our Sponsors, the Mills Family, our Other Pre-IPO Investors, and their respective affiliates also may pursue acquisition opportunities that may be complementary to our business, and, as a result, those acquisition opportunities may not be available to us. In addition, our Sponsors, the Mills Family, and our Other Pre-IPO Investors may have an interest in our pursuing acquisitions, divestitures, and other transactions that, in their judgment, could enhance their investment, even though such transactions might involve risks to us and our stockholders.

We will incur increased costs and become subject to additional regulations and requirements as a result of becoming a public company, which could lower our profits, make it more difficult to run our business, or divert management’s attention from our business.

As a public company, we will be required to commit significant resources and management time and attention to the requirements of being a public company, which will cause us to incur significant legal, accounting, and other expenses that we have not incurred as a private company, including costs associated with public company reporting requirements. We also will incur costs associated with the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) and related rules implemented by the Securities and Exchange Commission (the “SEC”) and Nasdaq, and compliance with these requirements will place significant demands on our legal, accounting, and finance staff and on our financial and information systems. In addition, we might not be successful in implementing these requirements. The expenses incurred by public companies generally for reporting and corporate governance purposes have been increasing. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly, although we are currently unable to estimate these costs with any degree of certainty. These laws and regulations also could make it more difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees, or as our executive officers. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of our Class A common stock, fines, sanctions, and other regulatory action and potentially civil litigation.

Failure to comply with requirements to design, implement, and maintain effective internal controls could have a material adverse effect on our business and stock price.

As a privately held company, we were not required to evaluate our internal control over financial reporting in a manner that meets the standards of publicly traded companies required by Section 404(a) of the Sarbanes-Oxley Act (“Section 404”).

As a public company, we will have significant requirements for enhanced financial reporting and internal controls. The process of designing and implementing effective internal controls is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a system of internal controls that is adequate to satisfy our reporting obligations as a public company. If we are unable to establish or maintain appropriate internal financial reporting controls and procedures, it could cause us to fail to meet our reporting obligations on a timely basis, result in material misstatements in our consolidated financial statements, and harm our results of operations. In addition, we will be required, pursuant to Section 404, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting in the second annual report following the completion

of this offering. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. The rules governing the standards that must be met for our management to assess our internal control over financial reporting are complex and require significant documentation, testing, and possible remediation. Testing and maintaining internal controls may divert our management’s attention from other matters that are important to our business. Additionally, our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting on an annual basis, beginning with our second annual report.

We are currently in the process of updating our control processes and automating certain of our procedures and systems in anticipation of becoming a public company, but our internal controls over financial reporting currently do not meet all of the standards contemplated by Section 404 that we will eventually be required to meet. Because we currently do not have comprehensive documentation of our internal controls and have not yet tested our internal controls in accordance with Section 404, we cannot conclude in accordance with Section 404 that we do not have a material weakness in our internal controls or a combination of significant deficiencies that could result in the conclusion that we have a material weakness in our internal controls. In connection with updating our control processes and the implementation of the necessary procedures and practices related to internal control over financial reporting, we have identified deficiencies and may identify deficiencies in the future that we may not be able to remediate in time to meet the deadline imposed by the Sarbanes-Oxley Act for compliance with the requirements of Section 404. In addition, we may encounter problems or delays in completing the remediation of any deficiencies identified by our independent registered public accounting firm in connection with the issuance of their attestation report. Our testing, or the subsequent testing (if required) by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses. Any material weaknesses could result in a material misstatement of our annual or quarterly consolidated financial statements or disclosures that may not be prevented or detected.

If securities or industry analysts do not publish research or reports about our business, or if they downgrade their recommendations regarding our Class A common stock, our stock price and trading volume could decline.

The trading market for our Class A common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If any of the analysts who cover us downgrade our Class A common stock or publish inaccurate or unfavorable research about our business, our Class A common stock price may decline. If analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our Class A common stock price or trading volume to decline and our Class A common stock to be less liquid.

There has been no prior market for our Class A common stock and an active trading market for our Class A common stock may never develop or be sustained, which may cause shares of our Class A common stock to trade at a discount from their initial offering price and make it difficult to sell the shares of Class A common stock you purchase.

Prior to this offering, there has not been a public trading market for shares of our Class A common stock. The initial public offering price per share of Class A common stock will be determined by agreement among us and the representatives of the underwriters and may not be indicative of the price at which shares of our Class A common stock will trade in the public market after this offering. If you purchase shares of our Class A common stock, you may not be able to resell those shares at or above the initial public offering price. We cannot predict the extent to which investor interest in the Company will lead to the development of an active trading market on Nasdaq or how liquid that market might become. An active public market for our Class A common stock may not develop or be sustained after the offering. If an active public market does not develop or is not sustained, it may be difficult for you to sell your shares of Class A common stock at a price that is attractive to you, or at all. The market price of our Class A common stock may decline below the initial public offering price.

We cannot predict the impact our dual class structure may have on the market price of our Class A common stock.

Each share of our Class A common stock and Class B common stock entitles its holder to one vote on all matters to be voted on by the stockholders generally. We cannot predict whether our dual class structure will result in a lower or more volatile market price of our Class A common stock, in adverse publicity, or other adverse consequences. Certain index providers have in the past announced restrictions on including companies with multiple class share structures in certain of their indices. Given the sustained flow of investment funds into passive strategies that seek to track certain indices, exclusion from stock indices would likely preclude investment by many of these funds and could make our Class A common stock less attractive to other investors. As a result, the market price of our Class A common stock could be materially adversely affected.

The market price of shares of our Class A common stock may be volatile or may decline regardless of our operating performance, which could cause the value of your investment to decline.

Even if a trading market develops, the market price of our Class A common stock may be highly volatile and could be subject to wide fluctuations. Securities markets worldwide experience significant price and volume fluctuations. This market volatility, as well as general economic, market or political conditions, could reduce the market price of shares of our Class A common stock, regardless of our operating performance. In addition, our operating results could be below the expectations of public market analysts and investors due to a number of potential factors, including variations in our quarterly operating results or dividends, if any, to stockholders, additions or departures of key management personnel, failure to meet analysts’ earnings estimates, publication of research reports about our industry, litigation and government investigations, changes or proposed changes in laws or regulations or differing interpretations or enforcement thereof affecting our business, adverse market reaction to any indebtedness we may incur or securities we may issue in the future, changes in market valuations of similar companies or speculation in the press or investment community, announcements by our competitors of significant contracts, acquisitions, dispositions, strategic partnerships, joint ventures, or capital commitments, adverse publicity about the industries we participate in or individual scandals, and in response the market price of shares of our Class A common stock could decrease significantly. You may be unable to resell your shares of Class A common stock at or above the initial public offering price.

Stock markets and the price of our Class A shares may experience extreme price and volume fluctuations. In the past, following periods of volatility in the overall market and the market price of a company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

Investors in this offering will suffer immediate and substantial dilution.

The initial public offering price per share of Class A common stock will be substantially higher than our pro forma net tangible book value per share immediately after this offering. As a result, you will pay a price per share of Class A common stock that substantially exceeds the per share book value of our tangible assets after subtracting our liabilities. In addition, you will pay more for your shares of Class A common stock than the amounts paid for the Common Units by the pre-IPO owners. See “Dilution.”

You may be diluted by the future issuance of additional Class A common stock or Common Units in connection with our incentive plans, acquisitions or otherwise.

After this offering we will have     shares of Class A common stock authorized but unissued, including     shares of Class A common stock issuable upon exchange of Common Units that will be held by the Continuing Common Unitholders (or     shares if the underwriters exercise their options to purchase additional shares of our Class A common stock). Our amended and restated certificate of incorporation authorizes us to issue these shares of Class A common stock and options, rights, warrants and appreciation rights relating to Class A common stock for the consideration and on the terms and conditions established by our board of directors in its sole

62

discretion, whether in connection with acquisitions or otherwise. Similarly, the amended and restated limited partnership agreement of Medline Holdings permits Medline Holdings to issue an unlimited number of additional partnership interests of Medline Holdings with designations, preferences, rights, powers and duties that are different from, and may be senior to, those applicable to the Common Units, and which may be exchangeable for shares of our Class A common stock. Additionally, we have reserved an aggregate of     shares of Class A common stock and Common Units for issuance under our Omnibus Incentive Plan, including shares of Class A common stock issuable following vesting and upon exchange for      as-converted Incentive Units held by the Continuing Incentive Unitholders with a weighted average participation threshold of $     per unit. For additional information concerning the awards under the Omnibus Incentive Plan that we intend to grant in connection with this offering or that will be outstanding at the time of this offering, see “Summary—The Offering.” There are also shares of Class A common stock reserved for issuance under our ESPP. Any Class A common stock that we issue, including under our Omnibus Incentive Plan, our ESPP, or other equity incentive plans that we may adopt in the future, would dilute the percentage ownership held by the investors who purchase Class A common stock in this offering. See “Dilution.”

We may issue preferred stock whose terms could materially adversely affect the voting power or value of our Class A common stock.

Our amended and restated certificate of incorporation will authorize us to issue, without the approval of our stockholders, one or more series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our Class A common stock respecting dividends and distributions, as our board of directors may determine. The terms of one or more series of preferred stock could adversely impact the voting power or value of our Class A common stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of the Class A common stock.

If we or our pre-IPO owners sell additional shares of our Class A common stock after this offering or are perceived by the public markets as intending to sell them, the market price of our Class A common stock could decline.

The sale of substantial amounts of shares of our Class A common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our Class A common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell shares of our Class A common stock in the future at a time and at a price that we deem appropriate. Upon completion of this offering, we will have a total of     shares of our Class A common stock outstanding, or     shares if the underwriters exercise in full their option to purchase additional shares of our Class A common stock. All of the shares of our Class A common stock sold in this offering will be freely tradable without restriction or further registration under the Securities Act, by persons other than our “affiliates,” as that term is defined under Rule 144 of the Securities Act. See “Shares Eligible for Future Sale.”

In addition, we and the Continuing Unitholders will enter into an exchange agreement under which they (or certain permitted transferees) will have the right, after the completion of this offering (subject to the terms of the exchange agreement), to exchange their Common Units (including Common Units issued upon conversion of vested Incentive Units) for shares of our Class A common stock on a one-for-one basis, subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications, whereupon an equivalent number of shares of Class B common stock held by each such Continuing Unitholder will be automatically transferred to us and cancelled and retired upon any such exchange. Upon completion of this offering (subject to the terms of the exchange agreement), an aggregate of     Common Units (or     Common Units if the underwriters exercise their option to purchase additional shares of our Class A common stock) may be exchanged for shares of our Class A common stock. Any shares we issue upon exchange of Common Units will be “restricted securities” as defined in Rule 144 and may not be sold in the absence of registration under the Securities Act unless an exemption from registration is available, including the exemptions contained in

63

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

Rule 144. Under applicable SEC guidance, we believe that for purposes of Rule 144 the holding period in such shares will generally include the holding period in the corresponding Common Units exchanged. We, our directors, executive officers, and holders of substantially all of our outstanding Common Units immediately prior to this offering have agreed, subject to certain exceptions, not to dispose of or hedge any shares of our Class A common stock (including shares issued upon exchange of Common Units) or securities convertible into or exchangeable for shares of our Class A common stock for 180 days from the date of this prospectus, except with the prior written consent of either Goldman Sachs & Co. LLC or Morgan Stanley & Co. LLC, and one additional representative, on behalf of the underwriters. See “Underwriting.” As a result of the registration rights agreement, however, all of these shares of our Class A common stock (including shares issued upon exchange of Common Units) may be eligible for future sale without restriction, subject to applicable lock-up arrangements. See “Shares Eligible for Future Sale—Registration Rights” and “Certain Relationships and Related Person Transactions—Registration Rights Agreement.”

Subject to certain limitations and exceptions, pursuant to the terms of the amended and restated limited partnership agreement of Medline Holdings, the Continuing Incentive Unitholders, which will hold      Incentive Units, which have a weighted-average per unit participation threshold of $   per Incentive Unit, will have the right to convert their vested Incentive Units into Common Units of Medline Holdings, as described in “Organizational Structure—Reclassification and Amendment and Restatement of the Limited Partnership Agreement of Medline Holdings” and “Certain Relationships and Related Person Transactions—Medline Holdings Amended and Restated Limited Partnership Agreement.” Common Units received upon conversion will be exchangeable on a one-for-one basis for shares of Class A common stock of Medline Inc. in accordance with the terms of the exchange agreement. At the time of this offering,    shares of Class A common stock would be issuable upon the exchange of an equivalent number of Common Units into which outstanding Incentive Units that are held by the Continuing Incentive Unitholders may be converted (assuming an offering price of $    per share of Class A common stock, which is the midpoint of the price range set forth on the cover of this prospectus, and assuming such Incentive Units are fully vested and converted to Common Units). In the event that the price of our Class A common stock increases, the number of Common Units a holder of vested Incentive Units would receive upon conversion of such Incentive Units would increase. See “Certain Relationships and Related Person Transactions—Medline Holdings Amended and Restated Limited Partnership Agreement.” The delivery of shares of Class A common stock upon exchange of Common Units received in conversion of Incentive Units will be registered on one or more registration statements on Form S-8, as described below.

Upon the expiration of the lock-up agreements described above, all of such shares will be eligible for resale in the public market, subject, in the case of shares held by our affiliates, to volume, manner of sale and other limitations under Rule 144. We expect that our Principal Stockholders will continue to be considered affiliates following the expiration of the lock-up period based on their expected share ownership and their board nomination rights. Certain of our other stockholders may also be considered affiliates at that time. However, subject to the expiration or waiver of the 180-day lock-up period, the holders of these shares of Class A common stock will have the right, subject to certain exceptions and conditions, to require us to register their shares of Class A common stock under the Securities Act, and they will have the right to participate in future registrations of securities by us. Registration of any of these outstanding shares of Class A common stock would result in such shares becoming freely tradable without compliance with Rule 144 upon effectiveness of the registration statement. See “Shares Eligible for Future Sale.”

We intend to file one or more registration statements on Form S-8 under the Securities Act to register shares of our Class A common stock or securities convertible into or exchangeable for shares of our Class A common stock issued pursuant to our Omnibus Incentive Plan and our ESPP. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market. We expect that the initial registration statement on Form S-8 will cover     shares of our Class A common stock.

In the future, we may also issue our securities in connection with investments or acquisitions. The amount of shares of our Class A common stock issued in connection with an investment or acquisition could constitute a material portion of our then outstanding shares of Class A common stock. As the lock-up period or other restrictions

on resale end, the market price of our shares of common stock could drop significantly if the holders of these restricted shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our Class A common stock or other securities or to use our Class A common stock as consideration for acquisitions of other businesses, investments, or other corporate purposes.

Anti-takeover provisions in our organizational documents and Delaware law might discourage or delay acquisition attempts for us that you might consider favorable.

Our amended and restated certificate of incorporation and amended and restated bylaws that will become effective immediately prior to the consummation of this offering will contain provisions that may make the merger or acquisition of our company more difficult without the approval of our board of directors. Among other things, these provisions:

We have elected not to be governed by Section 203 of the General Corporation Law of the State of Delaware (the “DGCL”), which is Delaware’s anti-takeover statute that, subject to certain exceptions and approvals, restricts “business combinations,” including specified mergers, asset sales, stock sales and other transactions, between a corporation and its subsidiaries, on the one hand, and any interested stockholder (generally defined to mean a person who, together with such person’s affiliates and associates, owns 15% or more of the outstanding voting stock of the corporation), on the other, for a three-year period following the time the person became an interested stockholder. However, our amended and restated certificate of incorporation contains similar provisions providing that we may not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder, unless the transaction fits within an enumerated exception, such as board approval of the business combination or the transaction that resulted in a person becoming an interested stockholder prior to the time such person became an interested stockholder. Our amended and restated certificate of incorporation provides that our Designating Stockholders and their affiliates, and any of their respective direct or indirect transferees, and any group as to which such persons are a party, do not constitute “interested stockholders” for purposes of this provision. See “Description of Capital Stock—Anti-Takeover Effects of Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws and Certain Provisions of Delaware Law—Business Combinations.” These anti-takeover provisions and other provisions under Delaware law could discourage, delay, or prevent a transaction involving a change in control of our company, including actions that our stockholders may deem advantageous, or negatively affect the trading price of our Class A common stock. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and to cause us to take other corporate actions you desire. For further discussion of these and other such anti-takeover provisions, see “Description of Capital Stock—Anti-Takeover Effects of Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws and Certain Provisions of Delaware Law.”

Our amended and restated certificate of incorporation will designate the Court of Chancery of the State of Delaware or the federal district courts of the United States of America, as applicable, as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with the Company or the Company’s directors, officers, or other employees.

Our amended and restated certificate of incorporation will provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by law, be the sole and exclusive forum for: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a breach of fiduciary duty owed by any current or former director, officer, stockholder or employee of the company to the company or our stockholders; (iii) any action asserting a claim against us arising under the DGCL, our amended and restated certificate of incorporation or our bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware; or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine.

Our amended and restated certificate of incorporation further will provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the federal securities laws of the United States, including, in each case, the applicable rules and regulations promulgated thereunder.

Any person or entity purchasing or otherwise acquiring any interest in any shares of our capital stock shall be deemed to have notice of and to have consented to the forum provision in our amended and restated certificate of incorporation. This choice-of-forum provision may limit a stockholder’s ability to bring a claim in a different judicial forum, including one that it may find favorable or convenient for a specified class of disputes with the Company or the Company’s directors, officers, other stockholders, or employees or result in increased costs for a stockholder to bring a claim, particularly if they do not reside in or near Delaware, each of which may discourage lawsuits against us or our directors, officers, other stockholders, or employees. Alternatively, if a court were to find this provision of our amended and restated certificate of incorporation inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could materially adversely affect our business, financial condition, and results of operations and result in a diversion of the time and resources of our management and board of directors.

A portion of the proceeds from this offering may be used to purchase or redeem outstanding equity interests from certain of our pre-IPO owners and will not be available to fund our operations.

We intend to use any proceeds from the issuance of shares pursuant to any exercise by the underwriters of their option to purchase additional shares of Class A common stock to purchase or redeem outstanding equity interests from certain pre-IPO owners at a price per equity interest equal to the initial public offering price per share of our Class A common stock less the underwriting discounts and commissions, as described under “Organizational Structure—Offering Transactions” and “Use of Proceeds.” Accordingly, we will not retain any of these proceeds, and none of these proceeds will be available to fund our operations, capital expenditures, or acquisition opportunities.

FORWARD-LOOKING STATEMENTS

These forward-looking statements are included throughout this prospectus, including in the sections entitled “Summary,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and “Business” and relate to matters such as our industry, business strategy, goals and expectations concerning our market position, future operations, margins, profitability, capital expenditures, liquidity and capital resources, and other financial and operating information. We may, in some cases, use words such as “anticipate,” “assume,” “believe” “contemplate,” “continue,” “could,” “estimate,” “expect,” “foreseeable,” “intend,” “may,” “plan,” “potentially,” “predict,” “project,” “seek,” “should,” “will,” or “would,” or similar words or phrases that convey uncertainty of future events or outcomes, to identify forward-looking statements in this prospectus.

The forward-looking statements contained in this prospectus are based on management’s current expectations and are subject to uncertainty and changes in circumstances. Although we believe that the assumptions underlying the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance, or achievements. There are a number of factors, many of which are beyond our control, that could cause actual results to differ materially from the results anticipated by these forward-looking statements. For a more detailed discussion of these and other factors, see the information under the section “Risk Factors” herein and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” These factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included in this prospectus. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, our actual results may vary in material respects from those expressed or implied in these forward-looking statements.

The forward-looking statements included in this prospectus speak only as of the date of this prospectus or as of the date they are made, as applicable. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We may not actually achieve the plans, intentions, or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures, investments, or other strategic transactions we may make. Except as otherwise required by law, we disclaim any intent or obligation to update any “forward-looking statement” made in this prospectus to reflect changed assumptions, the occurrence of unanticipated events, or changes to future operating results over time.

MARKET AND INDUSTRY DATA

This prospectus includes market and industry data and forecasts that we have derived from independent consultant reports, publicly available information, various independent industry publications, other independent sources, and our internal data, surveys, and estimates. Independent consultant reports, independent industry publications, and other independent sources generally indicate that the information contained therein was obtained from sources believed to be reliable.

Although we believe that these third-party sources are reliable, we do not guarantee the accuracy or completeness of this information, and neither we nor the underwriters have independently verified this information. Some market data and statistical information are also based on our good faith estimates, which are derived from management’s knowledge of our industry and such independent sources referred to above. Certain market, ranking, and industry data included elsewhere in this prospectus, including the size of certain markets and our size or position and the positions of our competitors within these markets, including our services relative to our competitors, are based on estimates of our management. These estimates have been derived from our management’s knowledge and experience in the markets in which we operate, as well as information obtained from surveys, reports by market research firms, our customers, distributors, suppliers, trade and business organizations, and other contacts in the markets in which we operate and have not been verified by independent sources. Our internal data and estimates are based upon information obtained from trade and business organizations and other contacts in the markets in which we operate, internal surveys, and our management’s understanding of industry conditions. Although we believe that such information is reliable, we have not had this information verified by any independent sources.

In addition, assumptions and estimates of our and our industry’s future performance are subject to a high degree of uncertainty and risk due to a variety of factors, including those described in “Risk Factors.” These and other factors could cause our future performance to differ materially from our assumptions and estimates. See “Forward-Looking Statements.” As a result, you should be aware that market, ranking, and other similar industry data included in this prospectus, and estimates and beliefs based on that data, may not be reliable. Neither we nor the underwriters can guarantee the accuracy or completeness of any such information contained in this prospectus.

Statements regarding our market position (including statements that we are the largest company in a particular market), unless otherwise noted, are based on our 2024 net sales in the relevant market relative to the publicly reported net sales of our competitors in such market, including with respect to our statement of being the largest provider of med-surg products and supply chain solutions serving all points of care, as that statement is based on our 2024 net sales relative to the publicly reported net sales of med-surg products by companies that are both med-surg manufacturers and distributors.

We define our TAM as the U.S. and international med-surg markets and calculate our TAM based on our customer footprint, competencies, and commercial strategy. As a result, our TAM figures exclude categories that could otherwise be considered as potentially addressable because we do not have current plans to directly pursue them through our manufacturing or sourcing networks. We define our SAM for Medline Brand products as the portion of our U.S. TAM directly addressable by our existing Medline Brand portfolio and capabilities. We calculate our TAM and SAM estimates included in this prospectus using internally prepared analyses that rely on independent data extracts and research, publicly available information regarding our competitors, and internal market estimates.

ORGANIZATIONAL STRUCTURE

Existing Organizational Structure

The diagram below depicts our current organizational structure.

Organizational Structure Following the Transactions

Immediately following this offering, Medline Inc. will be a holding company, and its sole material assets will be its equity interests held directly or indirectly through wholly owned subsidiaries in Medline Holdings. As the general partner of Medline Holdings, Medline Inc. will operate and control all of the business and affairs of Medline Holdings and, through Medline Holdings and its subsidiaries, conduct our business. The Reorganization Transactions lack economic substance and therefore will be accounted for in a manner consistent with a reorganization of entities under common control. As a result, the consolidated financial statements of Medline Inc. will recognize the assets and liabilities received in the reorganization at their historical carrying amounts, as reflected in the historical consolidated financial statements of Medline Holdings, the accounting predecessor. Medline Inc. will consolidate Medline Holdings in its consolidated financial statements and record a non-controlling interest related to the Units held by the Continuing Unitholders on its consolidated balance sheet and statement of income. As further described herein, prior to the completion of this offering:

71

Medline Inc. has requested confidential treatment of this registration statement and associated

correspondence pursuant to Rule 83 of the Securities and Exchange Commission.

Incentive Units received by Continuing Incentive Unitholders upon conversion of their Class B Units generally vest in equal annual installments over a period of five years from the date of grant, subject to the holder’s continued employment through the applicable vesting date. In addition, certain Incentive Units held by certain of our executive officers vest based on achievement of performance metrics tied to multiples of our Sponsors’ invested capital in Medline Holdings. See “Management—Outstanding Equity Awards at Fiscal Year End.” The Incentive Units are referred to as “Time-Vested Units” and “Performance-Vested Units” in such table.

Subject to certain restrictions, pursuant to the terms of the amended and restated limited partnership agreement of Medline Holdings, the holders of vested Incentive Units will have the right to convert their vested Incentive Units into a number of Common Units of Medline Holdings that will generally be equal to (a) the product of the number of vested Incentive Units to be converted with a given per unit participation threshold and then-current difference between the per unit value of a Common Unit at the time of the conversion (based on the public trading price of a share of Class A common stock) and the per unit participation threshold of such vested Incentive Units divided by (b) the per unit value of a Common Unit at the time of the conversion (based on the public trading price of a share of Class A common stock), subject to certain adjustments. Common Units received upon conversion will be exchangeable on a one-for-one basis for shares of Class A common stock of Medline Inc. in accordance with the terms of the exchange agreement. An unvested Incentive Unit will not be exchangeable unless and until such Incentive Unit vests. See “Certain Relationships and Related Person Transactions—Medline Holdings Amended and Restated Limited Partnership Agreement.”

The Continuing Common Unitholders will hold all of the initially outstanding shares of our Class B common stock, and, upon conversion of vested Incentive Units for Common Units, the converting holders will also receive an equivalent number of shares of Class B common stock. The shares of Class B common stock will have no economic rights but will entitle each holder to one vote for each share held of record on all matters to be voted on by stockholders generally, with the number of shares of Class B common stock held by each Continuing Unitholder being equivalent to the number of Common Units held by each such Continuing Unitholder. If at any time the ratio at which Common Units are exchangeable for shares of Class A common stock of Medline Inc. changes from one-for-one as described under “Certain Relationships and Related Person Transactions—Exchange Agreement,” the number of votes to which Class B common stockholders are entitled will be adjusted accordingly. Holders of shares of our Class B common stock will vote together with holders of our Class A common stock as a single class on all matters on which stockholders are entitled to vote generally, except as otherwise required by law.

Our post-offering organizational structure, as described above, is commonly referred to as an umbrella partnership-C-corporation (or UP-C) structure. This organizational structure will allow the Continuing

Unitholders to retain their equity ownership in Medline Holdings, an entity that is classified as a partnership for U.S. federal income tax purposes, in the form of Units. Investors in this offering, the Pre-IPO Stockholders, and the Exchanging Unitholders will, by contrast, hold their equity ownership in Medline Inc., a Delaware corporation that is a domestic corporation for U.S. federal income tax purposes, in the form of shares of Class A common stock. We believe that the Continuing Unitholders generally find it advantageous to continue to hold their equity interests in an entity that is not taxable as a corporation for U.S. federal income tax purposes. We do not believe that our UP-C organizational structure will give rise to any significant business or strategic benefit or detriment to us.

The diagram below depicts our organizational structure immediately following the Transactions.

Upon consummation of the Reorganization Transactions and immediately prior to this offering, our pre-IPO owners will hold shares and interests that may be exchanged or settled for an aggregate of      million shares of Class A common stock, which we refer to as the “diluted pre-IPO shares outstanding,” consisting of (i) issued and outstanding shares of Class A common stock held by our Pre-IPO Stockholders and Exchanging Unitholders; (ii) shares of Class A common stock issuable on a one-for-one basis in exchange for Common Units held by our Continuing Common Unitholders; (iii) shares of Class A common stock issuable on a one-for-one basis in exchange for Common Units into which outstanding Incentive Units that will be held by the Continuing

Incentive Unitholders may be converted; (iv) shares of Class A common stock in respect of RSUs to be granted to certain Exchanging Unitholders to compensate them for the loss of the opportunity to participate in the tax receivable agreement; (v) shares of Class A common stock issuable upon exercise of stock options to be granted to certain Exchanging Class B Unitholders in substitution for a portion of the economic benefit to which the Class B Units are entitled prior to this offering that is not reflected in the exchange of Class B Units to shares of Class A common stock; and (vi) shares of Class A common stock underlying RSUs to be held by certain independent non-employee members of our board of directors with respect to RSUs covering Class A Units.

Although the relative ownership among these categories of pre-IPO owners and the number of shares of Class A common stock into which their respective interests may be exchanged or settled will depend on the actual offering price, the total diluted pre-IPO shares outstanding will not change.

The table below sets forth the relative ownership of the diluted pre-IPO shares outstanding among our pre-IPO owners assuming an offering price at the low point, the midpoint and the high point, respectively, of the price range set forth on the front cover of this prospectus.

Incorporation of Medline Inc.

Medline Inc. was incorporated as a Delaware corporation on November 6, 2024. Medline Inc. has not engaged in any business or other activities except in connection with its formation and this offering. The amended and restated certificate of incorporation of Medline Inc. authorizes two classes of common stock, Class A common stock and Class B common stock, each having the terms described in “Description of Capital Stock.”

Blocker Transfers

Prior to this offering, our Pre-IPO Stockholders hold their interests in Medline Holdings through Blocker Companies that are taxable as corporations for U.S. federal income tax purposes. At the time of this offering, we will enter into certain restructuring transactions (such transactions, the “Blocker Transfers”) that will result in the Pre-IPO Stockholders acquiring      shares of newly issued Class A common stock in exchange for the acquisition by Medline Inc. of the Blocker Companies and, indirectly, the equivalent number of Common Units

held by the Blocker Companies. Each of the Blocker Companies will initially become a wholly owned subsidiary of Medline Inc. and will either be merged into Medline Inc. or will remain a wholly owned subsidiary that is part of the same consolidated group for U.S. federal income tax purposes.

Reclassification and Amendment and Restatement of the Limited Partnership Agreement of Medline Holdings

Prior to the completion of this offering, the limited partnership agreement of Medline Holdings will be amended and restated to, among other things, modify its capital structure by reclassifying its outstanding Class A Units and CUPI Units held by the Continuing Common Unitholders into a new class of limited partnership interests that we refer to as “Common Units” and reclassifying its outstanding Class B Units held by the Continuing Incentive Unitholders into a new class of limited partnership interests that we refer to as “Incentive Units.” We refer to this reclassification (the “Reclassification”) and amendment and restatement, together with the transactions described above under “—Blocker Transfers” and the entry into the exchange agreement and tax receivable agreement described below as the “Reorganization Transactions.” As a result of these transactions, our pre-IPO owners will hold their ownership interests directly in Medline Holdings (in the case of the Continuing Unitholders) or Medline Inc. (in the case of the Pre-IPO Stockholders and the Exchanging Unitholders). Immediately following the Reorganization Transactions but prior to the other Offering Transactions described below, there will be     Common Units issued and outstanding.

In connection with the Reclassification, Class A Units, CUPI Units, and all vested and unvested Class B Units held by the Exchanging Unitholders that are not reclassified into Units of Medline Holdings will be directly or indirectly exchanged for shares of Class A common stock (in the case of Class A Units, CUPI Units, and vested Class B Units) and restricted shares of Class A common stock (in the case of unvested Class B Units). The number of shares of Class A common stock delivered in respect of the units held by the Exchanging Unitholders will be determined based on the amount of proceeds that would be distributed to such units if the Company were to be sold at a value derived from the initial public offering price, and the intrinsic value of the shares of Class A common stock issued in respect of each unit will have a value equal to the hypothetical proceeds such unit would have received. Such shares of Class A common stock shall be restricted shares of Class A common stock, to the extent such shares related to unvested Class B Units, or vested shares of Class A common stock, to the extent such shares related to Class A Units, CUPI Units, or vested Class B Units. Assuming an offering price of $    per share of Class A common stock, which is the midpoint of the range on the front cover of this prospectus, the aggregate number of restricted shares of Class A common stock delivered in respect of the unvested Class B Units that are exchanged for restricted shares of Class A common stock in the Reclassification would be     and the aggregate number of vested shares of Class A common stock delivered in respect of the Class A Units, CUPI Units, and vested Class B Units that are exchanged for shares of Class A common stock in the Reclassification would be     .

In addition, we intend to (i) grant options to purchase shares of Class A common stock under the Omnibus Incentive Plan to certain Exchanging Class B Unitholders in substitution for a portion of the economic benefit to which the Class B Units are entitled prior to this offering that is not reflected in the exchange of Class B Units to shares of Class A common stock and (ii) grant RSUs in respect of Class A common stock to certain Exchanging Unitholders to compensate them for the loss of opportunity to participate in the tax receivable agreement in which they would have had the opportunity to participate had their units not been exchanged for shares of Class A common stock. The precise number of options we grant in respect of the Class B Units held by certain Exchanging Class B Unitholders will be determined based on the initial public offering price. Assuming an offering price of $    per share of Class A common stock, which is the midpoint of the range on the front cover of this prospectus, the aggregate number of such options granted to such Exchanging Class B Unitholders would be     . The precise number of RSUs we grant in respect of the units held by such Exchanging Unitholders will be based on the initial public offering price. Assuming an offering price of $    per share of Class A common stock, which is the midpoint of the range on the front cover of this prospectus, the aggregate number of RSUs granted to such Exchanging Unitholders would be    .

“Management—Compensation Arrangements to be Adopted in Connection with this Offering—Treatment of Existing Equity Interests” and “Management—Compensation Arrangements to be Adopted in Connection with this Offering—Equity Award Grants.”

Pursuant to the amended and restated limited partnership agreement of Medline Holdings, Medline Inc. will become the sole general partner of Medline Holdings. Accordingly, Medline Inc. will have the right to determine when distributions will be made to the holders of Common Units and the amount of any such distributions. If Medline Inc., as the general partner, authorizes a distribution, such distribution will be made to the holders of Common Units and any participating Incentive Units (as described below) pro rata in accordance with the percentages of their respective Common Units or Incentive Units, as applicable, held. Incentive Units initially will not be entitled to receive distributions (other than tax distributions) until holders of Common Units have received a minimum return as provided in the amended and restated limited partnership agreement of Medline Holdings. However, Incentive Units will have the benefit of adjustment provisions that will reduce the participation threshold for distributions in respect of which they do not participate until there is no participation threshold, at and after which time the Incentive Units would participate pro rata with distributions on Common Units.

The Continuing Unitholders, including Medline Inc., will incur U.S. federal, state, and local income taxes on their allocable share of any taxable income of Medline Holdings. Net profits and net losses of Medline Holdings will generally be allocated to its owners (including Medline Inc.) pro rata in accordance with the percentages of their respective Units held, except as otherwise required by law. The amended and restated limited partnership agreement will provide for cash distributions to the Continuing Unitholders if Medline Inc. determines that the taxable income of Medline Holdings will give rise to taxable income for such holders. In accordance with the amended and restated limited partnership agreement, we intend to cause Medline Holdings to make cash distributions to the Continuing Unitholders, including us, for purposes of funding their tax obligations in respect of the income of Medline Holdings that is allocated to them. Generally, these tax distributions will be computed based on our estimate of the taxable income of Medline Holdings allocated to the Continuing Unitholder that receives the greatest proportionate allocation of income multiplied by an assumed tax rate equal to 36% with respect to ordinary income or 30% with respect to capital gains or qualified dividend income, in each case, subject to adjustment by the board. Tax distributions will be pro rata as among the Common Units. See “Certain Relationships and Related Person Transactions—Medline Holdings Amended and Restated Limited Partnership Agreement.”

Subject to certain restrictions, pursuant to the terms of the amended and restated limited partnership agreement of Medline Holdings, the holders of vested Incentive Units will have the right to convert their vested Incentive Units into a number of Common Units of Medline Holdings that will generally be equal to (a) the product of the number of vested Incentive Units to be converted with a given per unit participation threshold and then-current difference between the per unit value of a Common Unit at the time of the conversion (based on the public trading price of a share of Class A common stock) and the per unit participation threshold of such vested Incentive Units divided by (b) the per unit value of a Common Unit at the time of the conversion (based on the public trading price of a share of Class A common stock), subject to certain adjustments. Common Units received upon conversion will be exchangeable on a one-for-one basis for shares of Class A common stock of Medline Inc. in accordance with the terms of the exchange agreement as described below. An unvested Incentive Unit will not be exchangeable unless and until such Incentive Unit vests.

Exchange Agreement

We and the Continuing Unitholders will enter into an exchange agreement at the time of this offering under which they (or certain permitted transferees thereof) may (subject to the terms of the exchange agreement) exchange their Common Units (including Common Units issued upon conversion of vested Incentive Units) for shares of our Class A common stock on a one-for-one basis, subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications, whereupon an equivalent number of shares of Class B common stock held by each such Continuing Unitholder will be automatically transferred to us and cancelled and retired

upon any such exchange. Class A common stock received by such Continuing Unitholder upon such exchanges during the applicable restricted periods described in “Shares Eligible for Future Sale—Lock-Up Agreements,” would be subject to the restrictions described in such section. The exchange agreement will also provide that a holder of Common Units will not have the right to exchange Common Units if Medline Inc. determines that such exchange would be prohibited by law or regulation or would violate other agreements with Medline Inc. to which the holder of Common Units may be subject. Medline Inc. may impose additional restrictions on exchange that it determines to be necessary or advisable so that Medline Holdings is not treated as a “publicly traded partnership” for U.S. federal income tax purposes. As a holder exchanges Common Units for shares of Class A common stock, the number of Common Units held by Medline Inc. is correspondingly increased as it acquires the exchanged Common Units. Holders of outstanding Common Units do not have the right to require a redemption of the Common Units. If at any time the ratio at which Common Units are exchangeable for shares of Class A common stock of Medline Inc. changes from one-for-one as described under “Certain Relationships and Related Person Transactions—Exchange Agreement,” the number of votes to which Class B common stockholders are entitled will be adjusted accordingly. See “Certain Relationships and Related Person Transactions—Exchange Agreement.”

Tax Receivable Agreement

Prior to the completion of this offering, Medline Inc. will enter into a tax receivable agreement with certain of our pre-IPO owners that provides for the payment by Medline Inc. to such pre-IPO owners of 90% of certain tax benefits, if any, that Medline Inc. actually realizes, or is deemed to realize (calculated using certain assumptions), as a result of (i) Medline Inc.’s allocable share of existing tax basis in Medline Holdings’ assets acquired in this offering, (ii) increases in Medline Inc.’s allocable share of existing tax basis and tax basis adjustments to the tangible and intangible assets of Medline Holdings as a result of sales or exchanges of Common Units (including Common Units issued upon conversion of vested Incentive Units) in connection with or after this offering, (iii) Medline Inc.’s utilization of certain tax attributes (including any existing tax basis) of the Blocker Companies, which Medline Inc. acquires in connection with this offering, and (iv) certain other tax benefits related to our entering into the tax receivable agreement, including tax benefits attributable to payments under the tax receivable agreement. Sales or exchanges of Common Units (including Common Units issued upon conversion of vested Incentive Units) are expected to result in increases in the tax basis of the assets of Medline Holdings. The existing tax basis, increases in existing tax basis, and the tax basis adjustments generated over time may increase (for tax purposes) depreciation and amortization deductions available to Medline Inc. and, therefore, may reduce the amount of U.S. federal, state, and local tax that Medline Inc. would otherwise be required to pay in the future. Actual tax benefits realized by Medline Inc. may differ from tax benefits calculated under the tax receivable agreement as a result of the use of certain assumptions in the tax receivable agreement, including the use of an assumed blended state and local income tax rate of 6% (as adjusted to take into account the U.S. federal tax benefit of such taxes) to calculate tax benefits. This payment obligation is an obligation of Medline Inc. and not of Medline Holdings. See “Certain Relationships and Related Person Transactions—Tax Receivable Agreement.”

Offering Transactions

Medline Inc. intends to use the proceeds (net of underwriting discounts and commissions) from the issuance by it of shares of Class A common stock in this offering (excluding any proceeds from the issuance of shares pursuant to any exercise by the underwriters of their option to purchase additional shares of Class A common stock) to acquire an equivalent number of newly issued Common Units from Medline Holdings. Assuming that the    shares of Class A common stock to be sold by Medline Inc. in this offering are sold at $    per share, which is the midpoint of the range on the front cover of this prospectus, at the time of this offering, Medline Inc. will acquire from Medline Holdings an equivalent number of newly issued Common Units for an aggregate of $     million. The issuance of such newly issued Common Units by Medline Holdings to Medline Inc. will correspondingly dilute the ownership interests of the Continuing Common Unitholders in Medline Holdings.

Medline Inc. intends to cause Medline Holdings, in turn, to use these proceeds for general corporate purposes, including the repayment of indebtedness, and to bear all of the expenses of this offering. See “Use of Proceeds.”

Medline Inc. will use any proceeds (net of underwriting discounts and commissions) from the issuance by it of shares of Class A common stock pursuant to any exercise by the underwriters of their option to purchase additional shares of Class A common stock to purchase or redeem outstanding Common Units and shares of Class A common stock from our pre-IPO owners at a price per equity interest equal to the initial public offering price per share of our Class A common stock less the underwriting discounts and commissions. Accordingly, we will not retain any of these proceeds. Assuming that the shares of Class A common stock to be sold by Medline Inc. in this offering are sold at $    per share, which is the midpoint of the range on the front cover of this prospectus, and assuming that the underwriters exercise their option to purchase     additional shares of Class A common stock in full, at the time of this offering, Medline Inc. will purchase or redeem from our pre-IPO owners an equivalent number of outstanding equity interests for an aggregate of $    million. See “Principal Stockholders” for additional information regarding the proceeds from this offering that will be paid to certain of our pre-IPO owners.

Accordingly, following this offering Medline Inc. will directly or indirectly hold a number of Common Units that is equal to the number of shares of Class A common stock that it has issued, a relationship that we believe fosters transparency because it results in a single share of Class A common stock representing (albeit indirectly) the same percentage equity interest in Medline Holdings as a single Common Unit.

As a result of the transactions described herein:

USE OF PROCEEDS

We estimate that the proceeds to Medline Inc. from this offering at an assumed initial public offering price of $     per share, which is the midpoint of the price range set forth on the cover page of this prospectus, after deducting estimated underwriting discounts and commissions, will be approximately $     million (or $     million if the underwriters exercise in full their option to purchase additional shares of Class A common stock). A $1.00 increase or decrease in the assumed initial public offering price of $     per share would increase or decrease, as applicable, the proceeds to Medline Inc. from this offering by approximately $     million, assuming the number of shares offered by us remains the same as set forth on the cover page of this prospectus and after deducting the estimated underwriting discounts and commissions (of which approximately $    million would be an increase or decrease, as applicable, in the cash available for general corporate purposes, including the repayment of indebtedness (specific indebtedness to be repaid to be identified in a later pre-effective amendment to the registration statement), and $    million would be an increase or decrease, as applicable, in the cash applied to redeem or repurchase shares of outstanding equity interests from certain pre-IPO owners as described below).

Medline Inc. intends to use the proceeds (net of underwriting discounts and commissions) from the issuance of shares in this offering (excluding any proceeds from the issuance of shares pursuant to any exercise by the underwriters of their option to purchase additional shares of Class A common stock) to acquire an equivalent number of newly issued Common Units from Medline Holdings, as described under “Organizational Structure—Offering Transactions,” which Medline Holdings will in turn use for general corporate purposes, including the repayment of indebtedness (specific indebtedness to be repaid to be identified in a later pre-effective amendment to the registration statement), and to bear all of the expenses of this offering. We estimate these offering expenses (excluding underwriting discounts and commissions) will be approximately $    million.

Medline Inc. intends to use any proceeds from the issuance of shares pursuant to any exercise by the underwriters of their option to purchase additional shares of Class A common stock to purchase or redeem outstanding Common Units and shares of Class A common stock from certain of our pre-IPO owners at a price per equity interest equal to the initial public offering price per share of our Class A common stock less the underwriting discounts and commissions, as described under “Organizational Structure—Offering Transactions.” Accordingly, we will not retain any of these proceeds. See “Principal Stockholders” for additional information regarding the proceeds from this offering that may be paid to certain of our pre-IPO owners.

DIVIDEND POLICY

We have no current plans to pay dividends on our Class A common stock following this offering. The declaration, amount and payment of any future dividends on shares of Class A common stock will be at the sole discretion of our board of directors subject to capital availability, applicable laws, and compliance with contractual restrictions and covenants in the agreements governing our current and future indebtedness, as well as our amended and restated certificate of incorporation. We may reduce or discontinue entirely the payment of such dividends at any time. Our board of directors may take into account general and economic conditions, our financial condition and operating results, our available cash, current and anticipated cash needs, capital requirements, contractual, legal, tax, and regulatory restrictions and implications on the payment of dividends by us to our stockholders or by our subsidiaries to us, and such other factors as our board of directors may deem relevant. Our amended and restated certificate of incorporation will provide that holders of Class B common stock shall not be entitled to any dividends on their shares of Class B common stock.

Medline Inc. is a holding company and has no material assets other than its ownership of Common Units held directly or indirectly through wholly owned subsidiaries in Medline Holdings. We intend to cause Medline Holdings to make distributions to us in an amount sufficient to cover our taxes, expenses, and obligations under the tax receivable agreement as well as any cash dividends declared by us. If Medline Holdings makes such distributions to Medline Inc., the other holders of Common Units and any participating Incentive Units (as described below) will also be entitled to receive distributions pro rata in accordance with the percentages of their respective Common Units or Incentive Units, as applicable, held. Incentive Units initially will not be entitled to receive distributions (other than tax distributions) until holders of Common Units have received a minimum return as provided in the amended and restated limited partnership agreement of Medline Holdings. However, Incentive Units will have the benefit of adjustment provisions that will reduce the participation threshold for distributions in respect of which they do not participate until there is no participation threshold, at and after which time the Incentive Units would participate pro rata with distributions on Common Units. The adjustment to the participation threshold of an Incentive Unit for distributions in respect of which such Incentive Unit does not participate will be factored into calculating the number of Common Units the holder of vested Incentive Units would receive upon conversion of a vested Incentive Unit for a Common Unit.

The amended and restated limited partnership agreement of Medline Holdings will provide that pro rata cash distributions be made to Continuing Unitholders (including Medline Inc.) at certain assumed tax rates, which we refer to as “tax distributions.” Tax distributions will be pro rata as among the Common Units. See “Certain Relationships and Related Person Transactions—Medline Holdings Amended and Restated Limited Partnership Agreement.” We anticipate that amounts received by Medline Inc. in certain periods are likely to exceed Medline Inc.’s actual tax liabilities and obligations to make payments under the tax receivable agreement. Our board of directors, in its sole discretion, will make any determination from time to time with respect to the use of any such excess cash so accumulated, which may include, among other uses, funding repurchases of Class A common stock; acquiring additional newly issued Common Units from Medline Holdings at a per unit price determined by reference to the market value of the Class A common stock; paying dividends, which may include special dividends, on its Class A common stock; or any combination of the foregoing. We also expect, if necessary, to undertake ameliorative actions, which may include pro rata or non-pro rata reclassifications, combinations, subdivisions or adjustments of outstanding Common Units, to maintain 1:1 parity between Common Units and shares of Class A common stock. See “Risk Factors—Risks Related to Our Organizational Structure—Medline Inc. is a holding company and its only material assets after completion of this offering will be its equity interests held directly or indirectly through wholly owned subsidiaries in Medline Holdings, and it is accordingly dependent upon distributions from Medline Holdings to pay taxes, make payments under the tax receivable agreement, and pay dividends.”

The credit agreement governing our Senior Secured Credit Facilities and the indentures governing our Senior Notes contain a number of covenants that restrict, subject to certain exceptions, the ability of the restricted subsidiaries of Medline Holdings to pay dividends or distributions to us. See “Description of Certain Indebtedness.”

Any financing arrangements that we enter into in the future may include restrictive covenants that limit our ability to pay dividends. In addition, Medline Holdings is generally prohibited under Delaware law from making a distribution to a member to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of Medline Holdings (with certain exceptions) exceed the fair value of its assets. Subsidiaries of Medline Holdings are generally subject to similar legal limitations on their ability to make distributions to Medline Holdings.
