Pfizer Reports Strong First-Quarter Results And Reaffirms 2026 Guidance

Pfizer Inc. (NYSE: PFE) reported financial results for the first quarter of 2026 and reaffirmed its full-year 2026 financial guidance⁽²⁾.

EXECUTIVE COMMENTARY

Dr. Albert Bourla, Chairman and CEO of Pfizer:

“We’re off to a strong start in 2026, and it reinforces our confidence that we will successfully navigate this defining period for Pfizer. Our R&D pipeline is advancing on multiple fronts – with positive Phase 3 readouts and encouraging mid-stage results building meaningful momentum – and I’m particularly encouraged by what we’re seeing in oncology and obesity, two areas where I believe Pfizer is positioned to lead.”

David Denton, CFO and EVP of Pfizer:

“Our first-quarter results are attributable to our solid commercial performance globally as well as our ongoing focus on operational efficiency. This quarter, I’m particularly pleased with the 22% year-over-year operational revenue growth from our launched and acquired products⁽¹⁾. Today, we are reaffirming our full-year 2026 financial guidance.”

OVERALL RESULTS

• First-Quarter 2026 Revenues of $14.5 Billion, Representing 2% Year-over-Year Operational Growth
  • Excluding Contributions from Comirnaty and Paxlovid, Revenues Grew 7% Operationally

  • Revenues of Launched and Acquired Products⁽¹⁾ Grew 22% Operationally

• First-Quarter 2026 Reported⁽³⁾ Diluted EPS of $0.47, and Adjusted⁽⁴⁾ Diluted EPS of $0.75

• Reaffirms All Components of Full-Year 2026 Financial Guidance⁽²⁾, including Revenues in a Range of $59.5 to $62.5 Billion and Adjusted⁽⁴⁾ Diluted EPS in a Range of $2.80 to $3.00

Beginning in the first quarter of 2026, we made organizational changes in our commercial organization within the Global Biopharmaceuticals Business (Biopharma) to better support and optimize performance across our product portfolios. These changes include the transition of certain off-patent branded and generic sterile injectables and biosimilars primarily from the Specialty Care and Oncology product portfolios to a new Hospital and Biosimilars product portfolio and the creation of a new Global Hospital and Biosimilars Division within Biopharma. See the Item 1. Business––Commercial Operations section of Pfizer’s 2025 Annual Report on Form 10-K (available at www.pfizer.com and www.sec.gov).

CAPITAL ALLOCATION

During the first three months of 2026, Pfizer deployed its capital in a variety of ways, which primarily included:

• Reinvesting capital into initiatives intended to enhance the future growth prospects of the company, including:
  • $2.5 billion invested in internal research and development projects, and

  • Approximately $110 million invested in business development transactions.

• Returning capital directly to shareholders through $2.4 billion of cash dividends, or $0.43 per share of common stock.

Our capital allocation framework is designed to enhance long-term shareholder value, and is based on three core pillars: (i) reinvesting in the business, including maintaining the flexibility to deploy capital towards potential value-creating business development transactions, (ii) maintaining and, over the long term, growing our dividend, and (iii) in the future, the potential to resume the return of capital to shareholders through value-enhancing share repurchases after de-levering our balance sheet. The company expects to continue to de-lever over the longer term in a prudent manner in order to maintain a balanced capital allocation strategy.

No share repurchases have been completed to date in 2026. As of May 5, 2026, Pfizer’s remaining share repurchase authorization is $3.3 billion. Current financial guidance does not anticipate any share repurchases in 2026.

Diluted weighted-average shares outstanding of 5,731 million and 5,710 million were used to calculate Reported⁽³⁾ and Adjusted⁽⁴⁾ diluted EPS for first-quarter 2026 and 2025, respectively.

QUARTERLY FINANCIAL HIGHLIGHTS (First-Quarter 2026 vs. First-Quarter 2025)

First-quarter 2026 revenues totaled $14.5 billion, an increase of $736 million, or 5%, compared to the prior-year quarter, reflecting an operational increase of $304 million, or 2%, and a favorable impact of foreign exchange of $431 million. The operational increase was primarily driven by an increase in revenues for Padcev, Eliquis, Oncology biosimilars, Nurtec and several other products across categories, partially offset primarily by a year-over-year decline in COVID-19 product revenues. Excluding contributions from Comirnaty and Paxlovid, revenues for the first quarter grew 7% operationally. Additionally, first-quarter revenues of our Launched and Acquired Products⁽¹⁾ grew 22% operationally.

First-quarter 2026 operational revenue growth was driven primarily by:

• Padcev globally, up 39% operationally, driven primarily by increased market share in first-line locally advanced or metastatic urothelial cancer (la/mUC) as well as contribution from launch momentum in the cisplatin-ineligible indication for muscle-invasive bladder cancer (MIBC);

• Eliquis globally, up 8% operationally, driven primarily by higher demand globally, partially offset by declines due to generic entry and price erosion in certain international markets;

• Oncology biosimilars globally, up 52% operationally, driven primarily by favorable net price in the U.S. and supply recovery, with both drivers partially reflecting one-time impacts;

• Nurtec ODT/Vydura globally, up 41% operationally, driven primarily by strong demand and one-time net price favorability in the U.S., as well as recent launches in certain international markets;

• Lorbrena globally, up 32% operationally, driven primarily by increased patient share in the first-line ALK-positive metastatic non-small cell lung cancer (ALK+ mNSCLC) treatment setting in the U.S., China, and certain other international markets;

• Vyndaqel family (Vyndaqel, Vyndamax, Vynmac) globally, up 4% operationally. International growth was primarily driven by strong demand with continuing uptake in patient diagnosis across markets as well as improved access in certain international markets. In the U.S., revenues declined primarily due to net price erosion as a result of new payer contracts, partially offset by continued market expansion;

• Xeljanz globally, up 34% operationally, driven primarily by favorable net price in the U.S., partially offset by lower demand internationally; and

• Abrysvo globally, up 31% operationally. U.S. growth was primarily driven by a lower returns provision compared to the prior-year quarter, partially offset by lower vaccine rates. International growth was primarily driven by launch uptake in certain international markets, partially offset by unfavorable timing of deliveries for the maternal indication in certain international markets;

partially offset primarily by lower revenues for:

• Comirnaty globally, down 59% operationally, driven primarily by a decline in international markets from both lower contractual deliveries and a lower favorable adjustment to the returns provision, as well as lower utilization in the U.S. primarily resulting from a narrower recommendation for vaccination; and

• Paxlovid globally, down 63% operationally, driven primarily by lower COVID-19 infections across U.S. and international markets and lower government purchases in certain international markets.

GAAP Reported⁽³⁾ Statement of Operations Highlights

SELECTED REPORTED⁽³⁾ COSTS AND EXPENSES

($ in millions)	First-Quarter

Effective Tax Rate on Reported(3) Income		14.6	%			(6.8	%)
* Indicates calculation not meaningful or results are greater than 100%.

First-quarter 2026 Cost of Sales⁽³⁾ as a percentage of revenues increased by 3.8 percentage points compared to the prior-year quarter, primarily driven by the non-recurrence of a favorable revision of our estimate of accrued royalties in the first quarter of 2025 as well as an unfavorable impact of foreign exchange.

First-quarter 2026 SI&A Expenses⁽³⁾ decreased 4% operationally compared to the prior-year quarter, primarily reflecting lower marketing and promotional spending on various products from more targeted investments and ongoing productivity improvements, as well as lower spending in corporate enabling functions; partially offset by an unfavorable impact of foreign exchange.

First-quarter 2026 R&D Expenses⁽³⁾ increased 12% operationally compared to the prior-year quarter, driven primarily by an increase in spending in certain oncology and obesity product candidates.

Pfizer’s effective tax rate on Reported⁽³⁾ income for the first quarter of 2026 increased compared to the prior-year quarter primarily due to an unfavorable change in the jurisdictional mix of earnings as well as the non-recurrence of favorable global income tax resolutions.

Product/Project	Milestone	Recent Development	Link
Braftovi (encorafenib)	Regulatory	February 2026. Announced the U.S. Food and Drug Administration (FDA) granted full approval to Braftovi in combination with cetuximab and fluorouracil-based chemotherapy for the treatment of adult patients with metastatic colorectal cancer (mCRC) with a BRAF V600E mutation based on results from the global Phase 3 BREAKWATER trial (NCT04607421). The Braftovi combination regimen is the only approved targeted regimen for first-line BRAF V600E-mutant metastatic colorectal cancer.	Full Release
	Phase 3 Results	February 2026. Announced positive topline progression-free survival (PFS) results from Cohort 3, a separate, randomized cohort of the pivotal BREAKWATER trial, evaluating Braftovi in combination with cetuximab and FOLFIRI (fluorouracil, leucovorin, and irinotecan) in patients with previously untreated metastatic colorectal cancer (mCRC) with a BRAF V600E mutation. The Braftovi regimen demonstrated a statistically significant and clinically meaningful improvement in PFS, a key secondary endpoint, as assessed by blinded independent central review (BICR) compared to treatment with FOLFIRI with or without bevacizumab. Overall survival (OS), a descriptive secondary endpoint, also showed clinically meaningful prolonged improvement with the Braftovi regimen. At the time of the PFS analysis, the safety profile of Braftovi in combination with cetuximab and FOLFIRI was consistent with the known profile of each regimen component and no new safety signals were identified.	Full Release
Elrexfio (elranatamab)	Phase 3 Results	April 2026. Announced positive topline results from the Phase 3 MagnetisMM-5 study evaluating Elrexfio as monotherapy in adults with relapsed or refractory multiple myeloma (RRMM) who received at least one prior line of treatment. The study demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of PFS, as assessed by BICR, versus standard-of-care daratumumab plus pomalidomide and dexamethasone. The safety and tolerability of Elrexfio was consistent with its known safety profile.	Full Release
Hympavzi (marstacimab)	Regulatory	March 2026. Announced the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion for Hympavzi to expand the approved indication to include patients 12 years of age and older weighing at least 35 kg with hemophilia A (congenital factor VIII [FVIII] deficiency) with FVIII inhibitors, or hemophilia B (congenital factor IX [FIX] deficiency) with FIX inhibitors. The European Commission will review the CHMP recommendation and is expected to make a final decision in the coming months.	Full Release
	Regulatory	February 2026. Announced the FDA accepted and granted priority review for the supplemental Biologics License Application (sBLA) for Hympavzi to expand the approved indication to include the treatment of hemophilia A or B patients 6 years and older with inhibitors, and pediatric patients (ages 6 to 11) with hemophilia A or B without inhibitors. The FDA has set a Prescription Drug User Fee Act (PDUFA) action date in the second quarter of 2026.	Full Release
Padcev (enfortumab vedotin)	Regulatory	April 2026. Pfizer and Astellas Pharma Inc. announced the FDA accepted for priority review a sBLA for perioperative (before and after surgery) Padcev in combination with pembrolizumab or pembrolizumab and berahyaluronidase alfa-pmph as treatment for patients with muscle-invasive bladder cancer (MIBC). This regimen was FDA-approved in November 2025 for use as perioperative treatment in cisplatin-ineligible patients with MIBC. This filing seeks to expand the indication to patients with MIBC regardless of cisplatin eligibility. The FDA has set a PDUFA target action date of August 17, 2026.	Full Release
	Phase 3 Results	February 2026. Pfizer and Astellas announced positive results from the investigational Phase 3 EV-304 clinical trial (also known as KEYNOTE-B15) for Padcev in combination with pembrolizumab in patients with MIBC eligible for cisplatin-based chemotherapy. Perioperative (before and after surgery) Padcev plus pembrolizumab demonstrated a 47% reduction in the risk of tumor recurrence, progression or death compared to patients treated with standard of care neoadjuvant (before surgery) gemcitabine and cisplatin (Hazard Ratio (HR) of 0.53; 95% Confidence Interval (CI), 0.41–0.70; 1-sided p<.0001).The safety profile for perioperative Padcev plus pembrolizumab observed in EV-304 was consistent with prior experience with the combination and there were no new safety signals.	Full Release
Talzenna (talazoparib)	Phase 3 Results	March 2026. Announced positive topline results from the investigational Phase 3 TALAPRO-3 study of Talzenna in combination with Xtandi in people with homologous recombination repair (HRR) gene-mutated metastatic castration-sensitive prostate cancer (mCSPC), also known as metastatic hormone-sensitive prostate cancer (mHSPC). The study met its primary endpoint, with Talzenna plus Xtandi demonstrating a statistically significant and clinically meaningful improvement in radiographic progression-free survival (rPFS), compared to placebo plus Xtandi. The results markedly exceeded the pre-specified target hazard ratio of 0.63, with the majority of patients remaining progression-free at the time of analysis. Consistent efficacy benefit was also observed in patients whose tumors harbored BRCA and non-BRCA HRR gene alterations. The safety of Talzenna plus Xtandi was consistent with the known safety profile of each medicine, and no new safety signals were identified.	Full Release

Pipeline Developments

A comprehensive update of Pfizer’s development pipeline was published today and is now available at www.pfizer.com/science/drug-product-pipeline. It includes an overview of Pfizer’s research and a list of compounds in development with targeted indication and phase of development, as well as mechanism of action for some candidates in Phase 1 and all candidates from Phase 2 through registration.

(2)		Pfizer does not provide guidance for U.S. generally accepted accounting principles (GAAP) Reported financial measures (other than revenues) or a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP Reported financial measures on a forward-looking basis because it is unable to predict with reasonable certainty the ultimate outcome of unusual gains and losses, certain acquisition-related expenses, gains and losses from equity securities, actuarial gains and losses from pension and postretirement plan remeasurements, potential future asset impairments and pending litigation without unreasonable effort. These items are uncertain, depend on various factors, and could have a material impact on GAAP Reported results for the guidance period.
		Financial guidance for full-year 2026 reflects the following:
		Does not assume the completion of any business development transactions not completed as of May 5, 2026.
		An anticipated unfavorable revenue impact of approximately $1.5 billion due to recent and expected generic and biosimilar competition for certain products that have recently lost patent or regulatory protection or that are anticipated to lose patent or regulatory protection.
		Exchange rates assumed are a blend of actual rates in effect through first-quarter 2026 and mid-April 2026 rates for the remainder of the year.
		Guidance for Adjusted(4) diluted EPS assumes diluted weighted-average shares outstanding of approximately 5.74 billion shares, and assumes no share repurchases in 2026.
(3)		Revenues is defined as revenues in accordance with U.S. GAAP. Reported net income and its components are defined as net income attributable to Pfizer Inc. common shareholders and its components in accordance with U.S. GAAP. Reported diluted earnings per share (EPS) is defined as diluted EPS attributable to Pfizer Inc. common shareholders in accordance with U.S. GAAP.
(4)		Adjusted income and Adjusted diluted earnings per share (EPS) are defined as U.S. GAAP net income attributable to Pfizer Inc. common shareholders and U.S. GAAP diluted EPS attributable to Pfizer Inc. common shareholders before the impact of amortization of intangible assets, certain acquisition-related items, discontinued operations and certain significant items. See the accompanying reconciliations of certain GAAP Reported to Non-GAAP Adjusted information for the first quarter of 2026 and 2025 in the press release at the hyperlink above. Adjusted income and its components and Adjusted diluted EPS measures are not, and should not be viewed as, substitutes for U.S. GAAP net income and its components and diluted EPS(3). See the Non-GAAP Financial Measure: Adjusted Income section of Management’s Discussion and Analysis of Financial Condition and Results of Operations in Pfizer’s 2025 Annual Report on Form 10-K and the accompanying Non-GAAP Financial Measure: Adjusted Income section of the press release located at the hyperlink above for a definition of each component of Adjusted income as well as other relevant information.
(5)		References to operational (Op) variances in this press release pertain to period-over-period changes that exclude the impact of foreign exchange rates. Although foreign exchange rate changes are part of Pfizer’s business, they are not within Pfizer’s control and because they can mask positive or negative trends in the business, Pfizer believes presenting operational variances excluding these foreign exchange changes provides useful information to evaluate Pfizer’s results.
(6)		Pfizer’s fiscal year-end for international subsidiaries is November 30 while Pfizer’s fiscal year-end for U.S. subsidiaries is December 31. Therefore, Pfizer’s first quarter for U.S. subsidiaries reflects the three months ended on March 29, 2026 and March 30, 2025, while Pfizer’s first quarter for subsidiaries operating outside the U.S. reflects the three months ended on February 22, 2026 and February 23, 2025.
