Income from Continuing Operations Before Provision/(Benefit) for Taxes on Income––The decrease in Income from continuing operations before provision/(benefit) for taxes on income of $1.4 billion to $3.3 billion in the third quarter of 2025 from $4.7 billion in the third quarter of 2024, was primarily due to an increase in Acquired in-process research and development expenses and lower revenues, partially offset by a decrease in Cost of sales.

Intellectual Property Rights and Collaboration/Licensing Rights––The loss, expiration or invalidation of intellectual property rights, patent litigation settlements and judgments, and the expiration of co-promotion and licensing rights can have a material adverse effect on our revenues. Certain of our products have experienced patent-based expirations or loss of regulatory exclusivity in certain markets in the last few years, and we expect certain products to face increased generic competition over the next few years. While additional patent-based or regulatory exclusivity expiries will continue, we expect a moderate impact of reduced revenues due to patent expiries in 2025 and anticipate a more significant impact of reduced revenues from patent-based or regulatory exclusivity expiries in 2026 through 2030 as several of our in-line products experience these expirations. We continue to vigorously defend our patent rights against infringement, and we will continue to support efforts that strengthen worldwide recognition of patent rights while taking necessary steps to help ensure appropriate patient access.

In the U.S., we expect to see continued focus by the U.S. government and states on regulating drug pricing and access to medicine, including but not limited to, international reference pricing, including Most-Favored-Nation (MFN) drug pricing. The drug pricing provisions of the IRA are being implemented over the next several years. In August 2023, CMS published the first ten medicines subject to the Medicare Drug Price Negotiation Program, which requires manufacturers of select drugs to engage in a process with the federal government to set new Medicare prices which would go into effect in 2026. Eliquis was among the first ten medicines subject to the Medicare Drug Price Negotiation Program. In August 2024, the government released the new Medicare price for Eliquis, which, effective January 1, 2026, will be required to be offered to all Medicare beneficiaries and to covered entities participating in the 340B Program that dispense Eliquis to a Medicare beneficiary if that maximum fair price is lower than the discounted price such entities are offered under the 340B Program ceiling price calculation. The Eliquis Medicare price is factored into our long-term financial planning, in accordance with our standard financial reporting and forecasting protocols. On January 17, 2025, CMS announced the selection of another 15 drugs from Medicare Part D for the maximum fair price, with prices to be set and effective on January 1, 2027. Ibrance and Xtandi were included in the list of 15 drugs selected. Another 15 drugs from Medicare Part B or Medicare Part D will be selected by February 1, 2026, for the maximum price to be set and in effect by January 1, 2028. It is possible that more of our products could be selected in future years, which could, among other things, lead to lower revenues prior to expiry of intellectual property protections. We continue to evaluate the impact of the IRA on our business, operations and financial condition and results as the full effect of the IRA on our business and the pharmaceutical industry remains uncertain. The IRA also made significant changes to the Medicare Part D benefit design (IRA Medicare Part D Redesign), which took effect beginning in 2025 and are impacting our revenues. In 2025, we expect a favorable impact from the $2,000 annual out-of-pocket cap and new Prescription Payment Plan, more than offset by an expected unfavorable impact from the sunsetting of the Coverage Gap Discount Program and the addition of new manufacturer discounts in the initial and catastrophic coverage phases, which we anticipate will have a net unfavorable impact to revenue in 2025 of approximately $1 billion, year-over-year. We expect a higher impact in the beginning of 2025, moderating through the remainder of the year, when compared to 2024. We expect these changes will more acutely impact our higher-priced medicines as they are expected to reach catastrophic coverage earlier in the year. In addition, changes to the Medicaid Drug Rebate…

Regulatory Environment/Pricing and Access––Government and Other Payor Group Pressures––Pricing and access pressures from governments globally, as well as private third-party payors in the U.S., continue to impact our global operations. With respect to the U.S., we expect to see continued focus by the U.S. government and states on regulating drug pricing and access to medicine, including but not limited to, international reference pricing, including Most-Favored-Nation (MFN) drug pricing. We continue to monitor and evaluate the implementation of the IRA, including the Medicare Drug Price Negotiation Program (MDPNP) and its government-set Maximum Fair Price which became effective for Eliquis on January 1, 2026. Negotiated prices for Ibrance and Xtandi are expected to follow in 2027, with Xeljanz effective in 2028. The IRA also made significant changes to the Medicare Part D benefit design (IRA Medicare Part D Redesign), which took effect beginning in 2025. We do not expect a material, incremental impact from the IRA Medicare Part D Redesign in 2026 versus the baseline set in 2025. In addition, changes to the Medicaid Drug Rebate Program or the 340B Program, including legal or legislative developments at the federal or state level with respect to the 340B Program, could have a material impact on our business.

Product Supply––We periodically encounter supply delays, disruptions and shortages, including due to voluntary product recalls and natural or man-made disasters. In response to requests from various regulatory authorities, manufacturers across the pharmaceutical industry, including Pfizer, are evaluating their product portfolios for the potential presence or formation of nitrosamines and we are actively engaging with regulatory authorities on this topic. If nitrosamines are detected in products, this may lead to submission of comprehensive data packages to regulatory authorities to support discussions on the relevant intake limit for the product and potential impact on patient supply, and, in some instances, may lead to market action for such products. For example, in 2021, Pfizer recalled Chantix due to the presence of a nitrosamine, N-nitroso-varenicline, at or above acceptable intake limits communicated by various regulatory authorities. Following issuance of updated guidance on acceptable intake limits for N-nitroso-varenicline by regulatory authorities, Chantix has returned to market in the U.S. and in certain international markets.

Changes in Tax Laws––Many countries outside the U.S. have enacted legislation for global minimum taxation resulting from the Organization for Economic Co-operation and Development’s (OECD) Base Erosion and Profit Shifting “Pillar 2” project.

The provisions are generally effective for Pfizer since 2024, though significant details and guidance around the provisions are still pending. Income tax expense could be impacted as the legislation becomes effective in countries in which we do business, and such impact could be material to our results of operations. We continue to monitor pending OECD guidance and legislation enactment and implementation by individual countries.
