SAF E H AR B O R S TAT E M E N T 2Baxter International This presentation includes forward-looking statements concerning the company’s financial results, business development and regulatory activities (including anticipated benefits and estimated timing) and Baxter’s 2030 Corporate Responsibility Commitment and goals. These forward-looking statements are based on assumptions about many important factors, including the following, which could cause actual results to differ materially from those in the forward-looking statements: the company’s ability to execute and complete strategic initiatives, asset dispositions and other transactions, including the proposed spinoff of the company’s Renal Care and Acute Therapies product categories; the company’s plans to simplify the company’s operating model and manufacturing footprint and the company’s review of strategic alternatives (including the proposed sale for the company’s BioPharma Solutions product category), the timing for such transactions, the ability to satisfy any applicable conditions and the expected proceeds, consideration and benefits; failure to accurately forecast or achieve the company’s short- and long-term financial improvement performance and goals (including with respect to the company’s strategic actions); the company’s ability to execute on its capital allocation plans, including the company’s debt repayment plans, the timing and amount of any dividends, share repurchases and acquisition proceeds and the capital structure of the public company that the company expects to form as a result of the proposed spinoff (and the resulting capital structure for the remaining company); the impact of global economic conditions (including, among other things, inflation levels, interest rates, financial market volatility, banking crises, the potential for a recession, the ongoing war in Ukraine, the related economic sanctions being imposed globally in response to the conflict and potential trade wars) and continuing public health crises, pandemics and epidemics, such as the ongoing COVID-19 pandemic, or the anticipation of any of the foregoing, on the company’s operations and on the company’s employees, customers and suppliers, including foreign governments in countries in which the company operates; downgrades to the company’s credit ratings or ratings outlooks, and the related impact on the company’s funding costs and liquidity; demand for and market acceptance risks for and competitive pressures related to new and existing products (including challenges with the company’s ability to accurately predict changing consumer preferences and future expenditures, which has led to and may continue to lead to increased inventory levels, and needs and advances in technology and the resulting impact on customer inventory levels and the impact of reduced hospital admission rates and elective surgery volumes), and the impact of those products on quality and patient safety concerns; the continuity, availability and pricing of acceptable raw materials and component parts (and the company’s ability to pass some or all of these costs to the company’s customers through recent price increases or otherwise), and the related continuity of the company’s manufacturing and distribution and those of the company’s suppliers; inability to create additional production capacity in a timely manner or the occurrence of other manufacturing, sterilization or supply difficulties (including as a result of natural disaster, public health crises and epidemics/pandemics, regulatory actions or otherwise); product development risks, including satisfactory clinical performance and obtaining and maintaining required regulatory approvals (including as a result of evolving regulatory requirements), the ability to manufacture at appropriate scale, and the general unpredictability associated with the product development cycle; the company’s ability to finance and develop new products or enhancements on commercially acceptable terms or at all; loss of key employees, the occurrence of labor disruptions or the inability to identify and recruit new employees; product quality or patient safety issues leading to product recalls, withdrawals, launch delays, warning letters, import bans, sanctions, seizures, litigation, or declining sales, including the focus on evaluating product portfolios for the potential presence or formation of nitrosamines; breaches or failures of the company’s information technology systems or products, including by cyber-attack, data leakage, unauthorized access or theft (as a result of remote working arrangements or otherwise); future actions of (or failures to act or delays in acting by) FDA, the European Medicines Agency or any other regulatory body or government authority (including the SEC, Department of Justice, the Federal Trade Commission, Centers for Medicare & Medicaid Services or the Attorney General of any State) that could delay, limit or suspend product development, manufacturing, sale or reimbursement or result in seizures, recalls, injunctions, monetary sanctions or criminal or civil liabilities, including the continued delay in lifting the warning letter at the company’s Ahmedabad facility; failures with respect to the company’s quality, compliance or ethics programs; future actions of third parties, including third-party payers and the company’s customers and distributors (including group purchasing organizations and integrated delivery networks), the impact of healthcare reform and its implementation, suspension, repeal, replacement, amendment, modification and other similar actions undertaken by the United States or foreign governments; the outcome of pending or future litigation, including the opioid, ethylene oxide and Linet antitrust litigation or other claims; the impact of competitive products and pricing, including generic competition, drug reimportation and disruptive technologies; global regulatory, trade and tax policies (including with respect to climate change and other sustainability matters); the ability to protect or enforce the company’s owned or in-licensed patent or other proprietary rights (including trademarks, copyrights, trade secrets and know-how) or patents of third parties preventing or restricting the company’s manufacture, sale or use of affected products or technology; the impact of any goodwill or other intangible asset impairments on the company’s operating results; fluctuations in foreign exchange and interest rates; any changes in law concerning the taxation of income (whether with respect to current or future tax reform); actions by tax authorities in connection with ongoing tax audits; and other risks identified in Baxter’s most recent filings on Form 10-K and Form 10-Q and other SEC filings, all of which are available on Baxter’s website. Baxter does not undertake to update its forward-looking statements unless otherwise required by the federal securities laws.

2 0 3 0 C O R P O R AT E R E S P O N S I B I L I T Y G OALS 12 PILLARS GOALS PERFORMANCE Reach More Underserved Kidney Patients Double the number of patients reached in underserved markets* through our peritoneal dialysis (PD) portfolio. *Countries outside of the United States, Canada, Western Europe, Japan, Korea, Australia and New Zealand. (Baseline: 198,000 patients in 2020) In 2022, we reached 204,000 patients in underserved markets through our PD portfolio. Given the number of barriers to care in these markets, we are taking a staged approach—beginning with awareness and education—that we intend to accelerate in future years Consistently Improve Manufacturing Capabilities Achieve a 10% year-over-year improvement in manufacturing process capability for prioritized products.* *As measured by the year-over-year decrease in defect rate until each product’s process capability goal is met. (Baseline year: 2021) In 2022, we exceeded our goal with a 16.4% improvement** compared with 2021 for our priority area of reducing the rate of leaks for sterilized solutions and sets. **Based on the eight sites fully active in the program during the reporting period; additional facilities have since been onboarded to the program. Achieve Carbon Neutrality for Direct Operations by 2040 Achieve carbon neutrality for our direct operations by 2040 and reduce absolute Scope 1 and 2 greenhouse gas emissions 25% by 2030, aligned with a well-below 2⁰ Celsius science-based target. In 2022, we reduced absolute Scope 1 and 2 greenhouse gas emissions by 1.7% compared with 2021 and 1.3% compared with our baseline year of 2020. Implement Strategic Water Management Plans Implement strategic water management plans at prioritized manufacturing locations.* *Identify prioritized locations using a risk-based approach by the end of 2023. In 2022, we completed four risk and resilience assessments (representing 22% of Baxter’s total water use) and performed eight wastewater compliance evaluations. We also continued infrastructure assessments for selected manufacturing sites and surveyed our manufacturing sites to collect critical data.** **The survey did not include former Hillrom manufacturing sites. Advance Sustainable Procurement Integrate Baxter’s sustainable procurement strategy across 90% of our supplier spend.* *As measured by supplier commitment to Baxter’s Ethics & Compliance Standards and Baxter’s completion of corporate responsibility audits within our supply base. In 2022, we confirmed commitment to Baxter’s Ethics & Compliance Standards for 51% of our suppliers, by spend (through related affirmations made in the underlying supplier contracts). In addition, we laid the foundation to begin conducting corporate responsibility audits or supplier surveys for any suppliers we identify as high risk based on supplier risk profiles and supplier corporate responsibility survey scores. Implement Strategic Materials and Waste Management Plans Implement prioritized waste mitigation opportunities* in Baxter’s integrated supply chain, from procurement to distribution. *Identify prioritized waste generation sources by the end of 2024. In 2022, we assessed warehouse waste management practices and aligned legacy Hillrom facilities with our waste management metrics. We also continued to mitigate waste through process efficiency, waste reduction at the source, reuse, recovery, recycling and landfill diversion. Invest in Underserved Communities Globally Invest $275 million in underserved communities through strategic partnerships and product donations from Baxter and the Baxter International Foundation. In 2022, Baxter and the Baxter International Foundation (the Foundation) invested $51 million in underserved communities through strategic partnerships and product donations. Since the beginning of 2021, we have invested nearly $103 million. Achieve Top Quartile Workplace Safety Performance Achieve top quartile workplace safety performance annually in total recordable incident rate.* *Among global companies across industries as reported by the U.S. Bureau of Labor Statistics. In 2022, Baxter's total recordable incident rate ranked in the top quartile, achieving our goal for the year.** **Compared with 2019 top quartile data, which was the most recent data available from the U.S. Bureau of Labor Statistics on January 1, 2022 (the beginning of the reporting period). Increase Representation of Women and Ethnic Minorities in Leadership Roles Through hiring, promotion and retention, aspire to increase representation of women in leadership roles globally to 40%.* *Assuming labor market conditions continue to support the goal. Leadership role is defined as director and above. As of Dec. 31, 2022, 35% of people in leadership roles at Baxter globally were women, down from 36% in 2021. Through hiring, promotion and retention, aspire to increase representation of ethnic minorities in leadership roles in the United States to 25%.* *Assuming labor market conditions continue to support the goal. Leadership role is defined as director and above. As of Dec. 31, 2022, 22% of people in leadership roles at Baxter in the United States were ethnic minorities, down from 24% in 2021. Note: The baseline for these goals is 2020 and the target achievement year is 2030, unless stated otherwise. EMPOWER OUR PATIENTS PROTECT OUR PLANET CHAMPION OUR PEOPLE AND COMMUNITIES Our 2030 Corporate Responsibility Goals support Baxter's top quartile goals, which include: Growth through innovation Patient safety and Quality Industry-leading performance Best place to work Baxter International
