EXECUTIVE COMMENTARY

Dr. Albert Bourla, Chairman and Chief Executive Officer, stated: “This is an exciting time for Pfizer as we are already executing on and rigorously planning for an unprecedented number of anticipated new product and indication launches, most of which are expected to occur in the second half of 2023. We have made excellent progress toward this goal already this year with the U.S. approvals for Zavzpret, Cibinqo for adolescents and Prevnar 20 in pediatric patients, and regulatory filing acceptances for a Braftovi + Mektovi sNDA, sNDA for the Talzenna and Xtandi combination, elranatamab BLA and our RSV maternal vaccine candidate — which, if approved, would be the first vaccine for administration to pregnant individuals to help protect against the complications of RSV disease in infants from birth up to six months of age.

During the first quarter, we announced plans to advance the battle against cancer with a definitive agreement to acquire Seagen, a global biotechnology company that discovers, develops and commercializes transformative oncology medicines. By combining Seagen’s category-leading antibody-drug conjugate (ADC) technology with Pfizer’s scale, expertise and capabilities, we believe we can accelerate breakthroughs in cancer medicines and introduce new solutions to patients around the world. Oncology remains a core therapeutic area for Pfizer, and we believe the proposed acquisition will enhance our position in this important space.

We believe the strength of our in-line products and expected near-term launches and revenue contribution from business development activities, including the proposed acquisition of Seagen, will position Pfizer to deliver robust operational growth through 2025 and beyond.”

David Denton, Chief Financial Officer and Executive Vice President, stated: “Our first-quarter results were in line with our expectations, underlining our continued confidence in achieving 7% to 9% operational revenue growth for fiscal-year 2023, excluding our COVID-19 products and anticipated foreign exchange impacts. We expect the majority of this growth to occur in the second half of 2023, given the timing of our expected near-term launches. Integration planning for our proposed acquisition of Seagen is underway, and we continue to expect the transaction to close in late 2023 or early 2024, subject to the satisfaction of customary closing conditions. As we de-lever our capital structure after the close, we expect our strong balance sheet will continue to provide the flexibility for future dividend increases and share repurchase activity, as well as additional business development activity.”

Results for the first quarter of 2023 and 2022⁽⁵⁾ are summarized below.

OVERALL RESULTS

REVENUES

Beginning in the third quarter of 2022, Pfizer made several organizational changes to further transform its operations to better leverage its expertise in certain areas and in anticipation of potential future new product and indication launches. These changes included establishing a new commercial structure within Biopharma focused on three broad customer groups (primary care, specialty care and oncology)⁽⁶⁾, optimizing Pfizer’s end-to-end R&D operations and further prioritizing its internal R&D portfolio, as well as realigning certain enabling and platform functions across the organization to ensure alignment with this new operating structure.

In addition, in the first quarter of 2023, Pfizer established an operating segment named Business Innovation that includes Pfizer CentreOne (PC1), the company’s global contract development and manufacturing organization and a leading supplier of specialty active pharmaceutical ingredients; and Pfizer Ignite, a recently launched offering that provides strategic guidance and end-to-end R&D services to select innovative biotech companies that align with Pfizer’s R&D focus areas.

Prior period amounts have been revised to conform to the current period presentation for all changes discussed above.

Some amounts in this press release may not add due to rounding. All percentages have been calculated using unrounded amounts. References to operational variances pertain to period-over-period changes that exclude the impact of foreign exchange rates⁽⁷⁾.

CAPITAL ALLOCATION

During the first three months of 2023, Pfizer deployed its capital in a variety of ways, which primarily include the following two categories:

• 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
• Returning capital directly to shareholders through $2.3 billion of cash dividends, or $0.41 per share of common stock.

No share repurchases have been completed to date in 2023. As of May 2, 2023, Pfizer’s remaining share repurchase authorization is $3.3 billion. Current financial guidance does not anticipate any share repurchases in 2023.

First-quarter 2023 diluted weighted-average shares outstanding used to calculate Reported⁽²⁾ and Adjusted⁽³⁾ diluted EPS were 5,727 million shares, a decrease of 31 million shares compared to the prior-year quarter, primarily due to shares repurchased in the first quarter of 2022, partially offset by shares issued for employee compensation programs.

2023 FINANCIAL GUIDANCE⁽⁴⁾

Pfizer reaffirms all components of its full-year 2023 financial guidance, which is presented below. This guidance includes management’s expectations for contributions from the entire company, including Comirnaty⁽¹⁾ and Paxlovid.

*Changes in foreign exchange rates have had a minimal incremental impact since full-year 2023 guidance was issued. Please refer to Press Release Footnote (4) for additional information.

The midpoint of the guidance range for revenues reflects a 31% operational decrease compared to 2022 revenues. Company revenues are anticipated to be lower in 2023 than in 2022 due entirely to expected revenue declines for Pfizer’s COVID-19 products.

Excluding COVID-19 products, the Company continues to expect 7% to 9% operational revenue growth in 2023.

Revenue guidance for Pfizer’s COVID-19 products is as follows:

• Comirnaty⁽¹⁾ revenues of approximately $13.5 billion, down 64% from 2022 results.
• Paxlovid revenues of approximately $8 billion, down 58% from 2022 results.
• In contrast to previous years, guidance for both products is no longer based primarily on expected deliveries under existing signed or committed supply contracts, but now also includes, among other things, anticipated sales through traditional commercial markets in the U.S. in the second half of 2023.

The midpoint of the guidance range for Adjusted⁽³⁾ diluted EPS reflects a 49% operational decrease compared to 2022, primarily driven by anticipated lower revenues from COVID-19 products, higher spending to support anticipated near-term launches and greater investment in certain late-stage pipeline projects.

Financial guidance for Adjusted⁽³⁾ diluted EPS is calculated using approximately 5.75 billion weighted average shares outstanding, and assumes no share repurchases in 2023.

Other components of Pfizer’s 2023 financial guidance are presented below.

Pfizer’s 2023 financial guidance is based on estimates and assumptions that are subject to significant uncertainties, particularly with regard to the anticipated performance of Comirnaty⁽¹⁾ and Paxlovid. See the Overview of Our Performance, Operating Environment, Strategy and Outlook — The Global Economic Environment section of Management’s Discussion and Analysis of Financial Condition and Results of Operations in Pfizer’s 2022 Annual Report on Form 10-K and Pfizer’s fourth-quarter 2022 earnings press release (available at www.pfizer.com) for additional information.

QUARTERLY FINANCIAL HIGHLIGHTS (First-Quarter 2023 vs. First-Quarter 2022)

First-quarter 2023 revenues totaled $18.3 billion, a decrease of $7.4 billion, or 29%, compared to the prior-year quarter, reflecting an operational decline of $6.6 billion, or 26%, primarily due to a decrease in Comirnaty⁽¹⁾ revenues globally, as well as an unfavorable impact of foreign exchange of $730 million, or 3%. First-quarter 2023 revenues from Comirnaty⁽¹⁾ and Paxlovid were $7.1 billion. Excluding contributions from Comirnaty⁽¹⁾ and Paxlovid, company revenues grew $563 million, or 5%, operationally.

Compared to the prior-year quarter, first-quarter 2023 revenue growth was unfavorably impacted by approximately 1% as a result of having one fewer selling day in international markets. This unfavorable impact is expected to reverse in the fourth quarter of 2023.

First-quarter 2023 Comirnaty⁽¹⁾ revenues declined $10 billion, or 75%, operationally compared with the prior-year quarter, largely driven by lower contracted deliveries and demand in international markets, as well as lower U.S. government contracted deliveries with anticipated transition to traditional commercial market sales in the second half of 2023.

First-quarter Paxlovid revenues increased $2.8 billion compared with the prior-year quarter, primarily driven by favorable timing of final delivery associated with the U.S. government contract before anticipated transition to traditional commercial markets in the second half of 2023; strong demand in China due to increased COVID-19 infections; and launch in certain international markets.

Excluding contributions from Comirnaty⁽¹⁾ and Paxlovid, first-quarter 2023 operational growth was primarily driven by:

• Recently acquired products, Nurtec ODT/Vydura and Oxbryta, which contributed $167 million and $71 million in global revenues, respectively;
• Sulperazon internationally, up 64% operationally, largely driven by demand in China, which is not expected to be sustained;
• Eliquis globally, up 7% operationally, driven primarily by continued oral anti-coagulant adoption and market share gains in the non-valvular atrial fibrillation indication in the U.S. and certain markets in Europe, partially offset by declines due to loss of exclusivity and generic competition in certain international markets; and
• Vyndaqel family (Vyndaqel, Vyndamax, Vynmac) globally, up 16% operationally, largely driven by continued strong uptake of the transthyretin amyloid cardiomyopathy (ATTR-CM) indication, primarily in the U.S. and developed Europe, partially offset by a planned price decrease that went into effect in Japan in the second quarter of 2022,

partially offset primarily by lower revenues for:

• Xeljanz globally, down 33% operationally, driven primarily by lower net price in the U.S. due to unfavorable changes in channel mix, as well as decreased prescription volumes worldwide resulting from ongoing shifts in prescribing patterns related to label changes.

GAAP Reported⁽²⁾ Income Statement Highlights

SELECTED REPORTED COSTS AND EXPENSES⁽²⁾

First-quarter 2023 Cost of Sales⁽²⁾ as a percentage of revenues decreased by 12.2 percentage points compared with the prior-year quarter, primarily driven by changes in sales mix, including lower sales of Comirnaty⁽¹⁾ and higher sales of Paxlovid.

First-quarter 2023 SI&A Expenses⁽²⁾ increased 35% operationally compared with the prior-year quarter, primarily reflecting increased investments to support Paxlovid, recently acquired and launched products, and products across multiple customer groups.

First-quarter 2023 R&D Expenses⁽²⁾ increased 10% operationally compared with the prior-year quarter, primarily driven by increased investments to develop recently acquired assets and certain vaccine programs, as well as activities to support upcoming product launches, partially offset by lower spending on programs to prevent and treat COVID-19 and certain other late-stage clinical programs.

First-quarter 2023 acquired IPR&D Expenses⁽²⁾ decreased 94% operationally compared to the prior-year quarter, primarily driven by the non-recurrence of an upfront payment to Biohaven Pharmaceutical Holding Company Ltd. (Biohaven) and a premium paid on Pfizer’s equity investment in Biohaven, as well as a premium paid on Pfizer’s equity investment in BioNTech SE (BioNTech) to develop a potential mRNA vaccine against shingles — both recorded in the first quarter of 2022.

Other deductions––net⁽²⁾ decreased 71% operationally in the first quarter of 2023 compared with the first quarter of 2022, primarily driven by lower net losses on equity securities, higher dividend income and lower net interest expense, partially offset by asset impairment charges in the first quarter of 2023, and lower net periodic benefit credits associated with pension and postretirement plans.

Pfizer’s effective tax rate on Reported income⁽²⁾ for the first quarter of 2023 decreased compared to the prior-year quarter primarily due to a favorable change in the jurisdictional mix of earnings.

RECENT NOTABLE DEVELOPMENTS (Since January 31, 2023)

Product Developments

• Braftovi (encorafenib) and Mektovi (binimetinib) – In April 2023, Pfizer announced the U.S. Food and Drug Administration (FDA) accepted for review the supplemental New Drug Applications (sNDAs) for Braftovi + Mektovi for patients with metastatic non-small cell lung cancer (NSCLC) with a BRAF V600E mutation, as detected by an FDA-approved test. The Prescription Drug User Fee Act (PDUFA) goal date for a decision by the FDA is in the fourth quarter of 2023 for the sNDAs.
• Cibinqo (abrocitinib) – In February 2023, Pfizer announced the FDA approved an sNDA for Cibinqo, expanding its indication to include adolescents (12 to <18 years) with refractory, moderate-to-severe atopic dermatitis whose disease is not adequately controlled with other systemic drug products, including biologics, or when use of those therapies is inadvisable. Cibinqo was previously approved in the U.S. only for the treatment of adults 18 years and older.
• Comirnaty (COVID-19 vaccine, mRNA)⁽⁸⁾
  • Regulatory Developments
    • In April 2023, the FDA amended the emergency use authorization (EUA) of the Pfizer-BioNTech Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine to simplify the vaccination schedule for most individuals. This action included authorizing the bivalent vaccine to be used for all doses administered to individuals six months of age and older, including for an additional dose or doses for certain populations such as older adults and the immunocompromised. The monovalent Pfizer-BioNTech COVID-19 vaccine is no longer authorized for emergency use in the U.S.
    • In March 2023, Pfizer and BioNTech announced the FDA granted EUA to provide a single 3-µg booster dose of the companies’ Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine in children six months through four years of age (also referred to as under five years of age) at least two months after completion of primary vaccination with three doses of the Pfizer-BioNTech COVID-19 Vaccine [Original]. Simultaneously, the FDA authorized the bivalent vaccine in this age group as the third dose of a three-dose primary series. The companies have submitted an application to the European Medicines Agency (EMA) to extend the Omicron BA.4/BA.5-adapted bivalent vaccine’s marketing authorization (MA) to include use in children six months through four years of age as both primary series (all three doses) and booster vaccination (fourth dose).
    • In February 2023, Pfizer and BioNTech announced the submission of a supplemental Biologics License Application (sBLA) to the FDA for approval of the companies’ Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine (Pfizer-BioNTech COVID-19 Vaccine, Bivalent (Original and Omicron BA.4/BA.5)) as a primary series and booster dose(s) for individuals 12 years of age and older. The companies have also submitted an application to the EMA for a variation of the MA to include the bivalent vaccine as a primary course of vaccination in individuals five years of age and older. In the European Union, the bivalent vaccine was previously granted full MA for administration as a booster dose in individuals five years of age and older.
• Paxlovid (nirmatrelvir [PF-07321332] tablets and ritonavir tablets)⁽⁸⁾ – In March 2023, Pfizer announced the FDA’s Antimicrobial Drugs Advisory Committee (AMDAC) voted that available data support the safety and effectiveness of Paxlovid for the treatment of mild-to-moderate COVID-19 in adult patients who are at high risk for progression to severe illness. The AMDAC's vote, while not binding, will be considered by the FDA when making its decision regarding the potential approval of Paxlovid. If approved by the FDA, Paxlovid could be the first U.S. FDA-approved oral treatment for COVID-19. The target PDUFA action date for a decision by the FDA is in May 2023.
• Prevnar 20 (20-valent pneumococcal conjugate vaccine) – In April 2023, Pfizer announced the FDA approved Prevnar 20 (20-valent Pneumococcal Conjugate Vaccine) for the prevention of invasive pneumococcal disease (IPD) caused by the 20 Streptococcus pneumoniae (pneumococcal) serotypes contained in the vaccine in infants and children six weeks through 17 years of age, and for the prevention of otitis media in infants six weeks through five years of age caused by the original seven serotypes contained in Prevnar. Prevnar 20 offers the broadest serotype coverage of any pediatric pneumococcal conjugate vaccine, helping to protect against all 20 serotypes contained in the vaccine.
• Talzenna (talazoparib) – In February 2023, Pfizer announced positive results from the Phase 3 TALAPRO-2 study of Talzenna, an oral poly ADP-ribose polymerase (PARP) inhibitor, in combination with Xtandi (enzalutamide), demonstrating a statistically significant and clinically meaningful improvement in radiographic progression-free survival (rPFS) compared to placebo plus Xtandi in men with metastatic castration-resistant prostate cancer (mCRPC), with or without homologous recombination repair (HRR) gene mutations. Additionally, the FDA granted priority review for Pfizer’s sNDA for Talzenna in combination with Xtandi for the treatment of men with mCRPC. The FDA’s decision on the sNDA is expected in 2023. In addition, the marketing authorization application (MAA) for this same indication has also been accepted for review by the EMA.
• Xtandi (enzalutamide) – In April 2023, Astellas Pharma and Pfizer announced that Xtandi plus leuprolide significantly reduced the risk of metastasis or death by 58% versus placebo plus leuprolide, as assessed by the primary endpoint of metastasis-free survival (MFS), in men with non-metastatic hormone-sensitive prostate cancer (nmHSPC; also known as non-metastatic castration-sensitive prostate cancer or nmCSPC) with high-risk biochemical recurrence (BCR). These data from the Phase 3 EMBARK trial were presented as a plenary session during the 2023 American Urological Association Annual Meeting, and detailed results from the trial will be submitted for peer-reviewed publication. Additionally, the EMBARK data will be discussed with regulatory authorities, including the FDA, to support a potential regulatory submission for Xtandi in this indication in 2023.
• Zavzpret (zavegepant) – In March 2023, Pfizer announced the FDA approved Zavzpret, the first and only calcitonin gene-related peptide (CGRP) receptor antagonist nasal spray for the acute treatment of migraine with or without aura in adults. In the pivotal Phase 3 study, published in The Lancet Neurology, Zavzpret was statistically superior to placebo on the co-primary endpoints of pain freedom and freedom from most bothersome symptom at two hours post-dose. The pivotal study also demonstrated pain relief as early as 15 minutes in a prespecified secondary endpoint versus placebo. In clinical trials, Zavzpret was well tolerated. Zavzpret is anticipated to be available in pharmacies in July 2023.

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.

• Elranatamab (PF-06863135) – In February 2023, Pfizer announced the FDA granted priority review for the company’s Biologics License Application (BLA) for elranatamab, an investigational B-cell maturation antigen (BCMA) CD3-targeted bispecific antibody (BsAb), for the treatment of patients with relapsed or refractory multiple myeloma (RRMM). The FDA’s decision on the application is expected in 2023. The EMA also accepted elranatamab’s MAA.
• RSVpreF (Respiratory Syncytial Virus (RSV) Bivalent Vaccine Candidate)
  • Pfizer today reports positive top-line results from the Phase 3 study evaluating the safety and immunogenicity of its RSV bivalent vaccine candidate, PF-06928316 or RSVpreF, coadministered with seasonal inactivated influenza vaccine (SIIV) in adults 65 years and older. The study met its primary endpoint, demonstrating non-inferiority for all four flu strains and both RSV groups. These results show that RSVpreF, if approved, can be administered concomitantly with SIIV.
  • In February 2023, Pfizer announced the FDA accepted for priority review a BLA for its respiratory syncytial virus (RSV) vaccine candidate, PF-06928316 or RSVpreF, for the prevention of medically attended lower respiratory tract illness (MA-LRTI) and severe MA-LRTI caused by RSV in infants from birth up to six months of age by active immunization of pregnant individuals. If approved, RSVpreF would be the first vaccine for administration to pregnant individuals to help protect against the complications of RSV disease in infants from birth through six months. The PDUFA goal date for a decision by the FDA is in August 2023. Pfizer also announced that the EMA accepted Pfizer’s MAA under accelerated assessment for its RSV vaccine candidate for both older adults and maternal immunization to help protect infants. A decision is expected in the second half of 2023.
  • In February 2023, Pfizer announced that the FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted that available data are adequate to support the safety and effectiveness of its RSV bivalent vaccine candidate, PF-06928316 or RSVpreF. The vaccine candidate is currently under FDA review for the prevention of acute respiratory disease and lower respiratory tract disease caused by RSV in adults 60 years of age and older. The FDA’s decision in older adults is expected by the PDUFA goal date in May 2023.
• Shingles (Varicella-zoster Virus, or VZV) mRNA Candidates – In February 2023, Pfizer and BioNTech announced the start of a Phase 1/2 trial exploring the safety, tolerability and immunogenicity of the companies’ mRNA vaccine candidates against shingles (also known as herpes zoster, or HZ). The study is aiming to enroll up to 900 healthy volunteers 50 through 69 years of age and is being conducted in the U.S. Phase 1 will help select the optimal mRNA vaccine candidate, dose level, dosing schedule and formulation for advancement to Phase 2. Participants in the study will be followed to determine how long protection may last.
• VLA15 (Lyme Disease Vaccine Candidate) – In February 2023, Pfizer and Valneva SE announced that Pfizer, as the study sponsor, decided to discontinue a significant percentage of participants in the U.S. who had been enrolled in the Vaccine Against Lyme for Outdoor Recreationists (VALOR) (NCT05477524) Phase 3 clinical study. These study participants, representing approximately half of the total recruited participants in the trial, are being discontinued following violations of Good Clinical Practice (GCP) at certain clinical trial sites run by a third-party clinical trial site operator. The discontinuation of these participants was not due to any safety concerns with the investigational vaccine and was not prompted by a participant-reported adverse event. The clinical trial remains ongoing at other sites not operated by the third party, and Pfizer continues to enroll new participants at those sites.

Corporate Developments

• In March 2023, Pfizer announced it entered into a definitive merger agreement under which Pfizer will acquire Seagen Inc., a global biotechnology company that discovers, develops and commercializes transformative cancer medicines, for $229 in cash per Seagen share for a total enterprise value of approximately $43 billion. Pfizer expects to finance the transaction substantially through $31 billion of new, long-term debt, and the balance from a combination of short-term financing and existing cash. The companies expect to complete the transaction in late 2023 or early 2024, subject to fulfillment of customary closing conditions, including approval of Seagen’s stockholders and receipt of required regulatory approvals. When combining the expected strong growth trajectories for Seagen’s in-line medicines with candidates that could emerge from Seagen’s pipeline, subject to clinical and regulatory success, Pfizer believes Seagen could contribute more than $10 billion in risk-adjusted revenues in 2030, with potential significant growth beyond 2030.
• In March 2023, it was announced that the Alliance between Merck KGaA, Darmstadt, Germany, (Merck KGaA) and Pfizer to co-develop and co-commercialize Bavencio (avelumab) will terminate. Effective June 30, 2023, Merck KGaA will take full control of the global commercialization of Bavencio. The current profit share will be replaced by a 15% royalty to Pfizer on net sales of Bavencio. Merck KGaA and Pfizer will continue to operationalize their respective ongoing clinical trials for Bavencio; and Merck KGaA will control all future research and development activities.

(1) As used in this document, “Comirnaty” refers to, as applicable, and as authorized or approved, the Pfizer-BioNTech COVID-19 Vaccine, the Pfizer-BioNTech COVID-19 Vaccine, Bivalent (Original and Omicron BA.4/BA.5), the Comirnaty Original/Omicron BA.1 Vaccine, and Comirnaty Original/Omicron BA.4/BA.5 Vaccine. In the U.S., monovalent mRNA COVID-19 vaccines are no longer emergency use authorized or CDC-recommended, although Comirnaty remains a licensed vaccine. “Comirnaty” includes direct sales and alliance revenues related to sales of the above-mentioned vaccines, which are recorded within Pfizer’s Primary Care customer group. It does not include revenues for certain Comirnaty-related manufacturing activities performed on behalf of BioNTech, which are included in the Pfizer CentreOne contract development and manufacturing organization. Revenues related to these manufacturing activities totaled $5 million for the first quarter of 2023 and $47 million for the first quarter of 2022.

(2) Revenues is defined as revenues in accordance with U.S. generally accepted accounting principles (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.

(3) Adjusted income and Adjusted diluted EPS are defined as U.S. GAAP net income attributable to Pfizer Inc. common shareholders and Reported 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 2023 and 2022. 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⁽²⁾. 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 2022 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.

(4) Pfizer does not provide guidance for GAAP Reported financial measures (other than revenues and acquired in-process R&D (IPR&D) expenses) 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 2023 reflects the following:

• Does not assume the completion of any business development transactions not completed as of April 2, 2023, except for signed transactions, if any, through mid-April 2023, which are expected to give rise to acquired IPR&D expenses during fiscal 2023.
• Reflects an anticipated negative revenue impact of $0.2 billion due to recent and expected generic and biosimilar competition for certain products that have recently lost patent protection or that are anticipated to lose patent protection during fiscal-year 2023.
• Exchange rates assumed are a blend of actual rates in effect through the first quarter of 2023 and mid-April 2023 rates for the remainder of the year. Financial guidance reflects the anticipated unfavorable impact of approximately $0.4 billion on revenues and approximately $0.13 on Adjusted⁽³⁾ diluted EPS as a result of changes in foreign exchange rates relative to the U.S. dollar compared to foreign exchange rates from 2022.
• Guidance for Adjusted⁽³⁾ diluted EPS assumes diluted weighted-average shares outstanding of approximately 5.75 billion shares, and assumes no share repurchases in 2023.

(5) 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 April 2, 2023 and April 3, 2022, while Pfizer’s first quarter for subsidiaries operating outside the U.S. reflects the three months ended on February 26, 2023 and February 27, 2022.

(6) Beginning in the third quarter of 2022, Pfizer made several organizational changes to further transform its operations to better leverage its expertise in certain areas and in anticipation of potential future new product and indication launches. Biopharma, Pfizer’s innovative science-based biopharmaceutical business, is operating under a new commercial structure designed to better support and optimize performance across three broad customer groups:

• Primary Care, consisting of the former Internal Medicine and Vaccines product portfolios, products for COVID-19 prevention and treatment, and potential future mRNA and antiviral products.
• Specialty Care, consisting of the former Inflammation & Immunology, Rare Disease and Hospital (excluding Paxlovid) product portfolios.
• Oncology, consisting of the former Oncology product portfolio.

(7) References to operational variances in this press release pertain to period-over-period changes that exclude the impact of foreign exchange rates. Although 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.

(8) Paxlovid and the Pfizer-BioNTech COVID-19 Vaccine, Bivalent (Original and Omicron BA.4/BA.5) have not been approved or licensed by the FDA. Paxlovid has been authorized for emergency use by the FDA under an EUA, for the treatment of mild-to-moderate COVID-19 in adults and pediatric patients (12 years of age and older weighing at least 40 kg) with a current diagnosis of mild-to-moderate COVID-19 and who are at high risk for progression to severe COVID-19, including hospitalization or death. The Pfizer-BioNTech COVID-19 Vaccine, Bivalent has been authorized by the FDA under an EUA to prevent COVID-19 in individuals aged 6 months and older. The emergency uses are only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of the medical product during the COVID-19 pandemic under Section 564(b)(1) of the FFDCA unless the declaration is terminated or authorization revoked sooner.
