EXECUTIVE COMMENTARY

Dr. Albert Bourla, Chairman and Chief Executive Officer, stated: "2022 was a record-breaking year for Pfizer, not only in terms of revenue and earnings per share, which were the highest in our long history, but more importantly, in terms of the percentage of patients who have a positive perception of Pfizer and the work we do. As proud as we are about what we have accomplished, our focus is always on what is next. As we turn to 2023, we expect to once again set records, with potentially the largest number of new product and indication launches that we've ever had in such a short period of time. We believe that the combination of these expected near-term launches, additional pipeline products that could potentially come to market in the medium-term, and anticipated contributions from business development, has the potential to set the company up for continued robust growth through the rest of this decade and beyond."

David Denton, Chief Financial Officer and Executive Vice President, stated: "I am very pleased with our fourth-quarter performance, which was highlighted by strong operational growth from Paxlovid, Prevnar 20, Comirnaty, Vyndaqel and Eliquis, as well as the inclusion of Nurtec ODT/Vydura and Oxbryta. For the full-year, we achieved revenues of over $100 billion, including 10 medicines or vaccines that generated revenues of more than $1 billion each, and all of this was accomplished despite operating in an environment in which foreign exchange reduced our revenues by 7%. Looking forward to 2023, we expect strong topline growth of 7% to 9% excluding our COVID-19 products and anticipated foreign exchange impacts. We are also increasing our investments behind our launch products and pipeline in order to help realize our growth goals for 2023 and beyond."

Results for the fourth-quarter and full-year 2022 and 2021 ⁽⁵⁾ are summarized below.

OVERALL RESULTS

REVENUES

Beginning in the first quarter of 2022, Pfizer implemented changes to its Adjusted ⁽³⁾ financial measures with respect to acquired in-process research and development (IPR&D) costs and amortization of intangibles. More information about these changes and their impact on the periods presented can be found in the Non-GAAP Financial Measure: Adjusted Income section of the press located at the hyperlink below.

Beginning in the third quarter of 2022, Pfizer has 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 or indication launches. These changes include establishing a new commercial structure within Biopharma focused on three broad customer groups (primary care, specialty care and oncology) ⁽⁶⁾ , optimizing our end-to-end R&D operations and further prioritizing our internal R&D portfolio, as well as realigning certain enabling and platform functions across the organization to ensure alignment with this new operating structure.

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

Business development activities ⁽⁷⁾ completed in 2021 and 2022 ⁽⁵⁾ impacted financial results in the periods presented. 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 ⁽⁸⁾ .

2023 FINANCIAL GUIDANCE ⁽⁴⁾

Pfizer's 2023 financial guidance is presented below. This guidance includes management's expectations for contributions from the entire company, including Comirnaty ⁽¹⁾ and Paxlovid.

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 actual 2022 results.

• Paxlovid revenues of approximately $8 billion, down 58% from actual 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 investments in certain late-stage pipeline projects.

Financial guidance for Adjusted diluted EPS ⁽³⁾ 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 which are subject to significant uncertainties, particularly with regard to the anticipated performance of Comirnaty ⁽¹⁾ and Paxlovid, for which patient demand could be significantly impacted by the infectiousness and severity of the predominant strains of the virus during 2023.

Key assumptions incorporated within the guidance follow.

* Only includes markets where Paxlovid is available, and only includes individuals age 12+/18+ where authorized/approved in accordance with local labeling.
† Actual 2022 market data is derived from a combination of public data sources and internal market research.

CAPITAL ALLOCATION

During full-year 2022, Pfizer deployed its capital in a variety of ways, which primarily include the following two broad categories:

• Reinvesting capital into initiatives intended to enhance the future growth prospects of the company, including:
  • $11.4 billion invested in internal research and development projects, and
  • Approximately $26 billion invested in completed business development transactions, net of cash acquired, including approximately $12.7 billion ⁽⁷⁾ for the acquisition of Biohaven Pharmaceutical Holding Company Ltd. (Biohaven), $6.4 billion ⁽⁷⁾ for the acquisition of Arena Pharmaceuticals, Inc. and approximately $5.6 billion ⁽⁷⁾ for the acquisition of Global Blood Therapeutics, Inc. (GBT).
• Returning capital directly to shareholders through a combination of:
  • $9.0 billion of cash dividends, or $1.60 per share of common stock, and
  • $2.0 billion, which was used to repurchase 39.1 million shares on the open market in March 2022, at an average cost of $51.10 per share.

As of January 31, 2023, Pfizer's remaining share repurchase authorization is $3.3 billion. Current financial guidance does not anticipate any share repurchases in 2023.

Fourth-quarter 2022 diluted weighted-average shares outstanding used to calculate Reported ⁽²⁾ and Adjusted ⁽³⁾ diluted EPS were 5,743 million shares, a decrease of 26 million shares compared to the prior-year quarter, primarily due to shares repurchased in first-quarter 2022, partially offset by shares issued for employee compensation programs.

QUARTERLY FINANCIAL HIGHLIGHTS (Fourth-Quarter 2022 vs. Fourth-Quarter 2021)

Fourth-quarter 2022 revenues totaled $24.3 billion, an increase of $452 million, or 2%, compared to the prior-year quarter, reflecting operational growth of $3.0 billion, or 13%, as well as an unfavorable impact of foreign exchange of $2.5 billion, or 11%. Excluding contributions from Paxlovid and Comirnaty ⁽¹⁾ , company revenues grew $571 million, or 5%, operationally.

Fourth-quarter 2022 operational growth was primarily driven by:

• Comirnaty ⁽¹⁾ in developed markets, up 67% operationally, driven primarily by the resumption of deliveries of the Omicron-adapted bivalent booster following a previously announced period of significantly lower deliveries of the original vaccine during third-quarter 2022, primarily involving the European Union (EU) and Japan;
• Paxlovid outside the U.S., which contributed $1.8 billion in revenues, driven by international launches in late 2021 and early 2022 following regulatory approvals or emergency use authorizations (EUAs);
• Prevnar family (Prevnar 13 & 20) in the U.S., up 79%, driven primarily by strong patient demand following the launch of Prevnar 20 for the eligible adult population and favorable timing of Centers for Disease Control and Prevention (CDC) purchasing of the pediatric indication, partially offset by a reduction in revenues due to a one-time CDC inventory return program for the pediatric indication, the revenue impact of which is expected to be reversed in 2023 upon replenishment;
• Revenues from recently acquired products, Nurtec ODT/Vydura and Oxbryta, which contributed $211 million and $73 million in global revenues, respectively;
• Vyndaqel family (Vyndaqel, Vyndamax, Vynmac) globally, up 31% operationally, driven by continued strong uptake of the transthyretin amyloid cardiomyopathy indication, primarily in developed Europe and the U.S., partially offset by a planned price decrease that went into effect in Japan in second-quarter 2022;
• Eliquis in the U.S., up 17%, driven primarily by continued oral anti-coagulant adoption and market share gains in non-valvular atrial fibrillation, as well as favorable changes in channel mix; and
• Prevenar 13 in emerging markets, up 22% operationally, driven primarily by strong growth in China and favorable timing of sales to GAVI, the Vaccine Alliance,

partially offset primarily by lower revenues for:

• Comirnaty ⁽¹⁾ in emerging markets, down 81% operationally, primarily due to lower demand for COVID-19 vaccines;
• Xeljanz globally, down 28% operationally, driven primarily by declines in net price due to unfavorable changes in channel mix in the U.S. and decreased prescription volumes globally resulting from ongoing shifts in prescribing patterns related to label changes;
• Sutent globally, down 50% operationally, primarily driven by lower volume demand in Europe following its loss of exclusivity in January 2022;
• Ibrance globally, down 4% operationally, driven primarily by increases in the proportion of patients accessing Ibrance through the U.S. Patient Assistance Program, planned price decreases that recently went into effect in international developed markets and prior-year clinical trial purchases internationally, partially offset by higher volumes across multiple regions; and
• Eliquis internationally, down 7% operationally, primarily driven by declines in certain emerging markets.

GAAP Reported ⁽²⁾ Income Statement Highlights

SELECTED REPORTED COSTS AND EXPENSES ⁽²⁾

* Indicates calculation not meaningful.

Fourth-quarter 2022 Cost of Sales ⁽²⁾ as a percentage of revenues decreased 1.1 percentage points compared with the prior-year quarter. The decrease was primarily driven by favorable changes in sales mix, including increased sales of Paxlovid and higher alliance revenues, as well as favorable impacts resulting from changes in foreign exchange rates, partially offset by approximately $600 million and approximately $200 million of inventory write-offs related to Paxlovid and Comirnaty ⁽¹⁾ , respectively, and higher operational revenues for Comirnaty ⁽¹⁾ .

SI&A Expenses ⁽²⁾ increased 17% operationally compared with the prior-year quarter, primarily reflecting increased investments to support Paxlovid, Comirnaty ⁽¹⁾ and recently acquired and launched products.

Fourth-quarter 2022 R&D Expenses ⁽²⁾ increased 7% operationally compared with the prior-year quarter, primarily driven by increased costs to support various vaccine and oncology programs, as well as spending related to recently acquired assets, partially offset by lower spending on programs to treat COVID-19 and certain other late-stage clinical programs.

Acquired IPR&D Expenses ⁽²⁾ decreased 97% operationally compared with the prior-year quarter. The acquisitions of Biohaven and GBT in fourth-quarter 2022 qualified as business combinations under U.S. Generally Accepted Accounting Principles (GAAP), resulting in no Acquired IPR&D Expenses ⁽²⁾ , while the acquisition of Trillium Therapeutics Inc. in fourth-quarter 2021 was accounted for as an asset acquisition, giving rise to approximately $2.1 billion in Acquired IPR&D Expenses.

Other income––net ⁽²⁾ increased 13% operationally in fourth-quarter 2022 compared with fourth-quarter 2021, primarily driven by net gains on equity securities in fourth-quarter 2022 versus net losses on equity securities recognized in the prior-year quarter and lower net interest expense, partially offset by lower net periodic benefit credits associated with pension and postretirement plans and higher asset impairment charges.

Pfizer's effective tax rate on Reported income ⁽²⁾ for fourth-quarter 2022 decreased compared to the prior-year quarter primarily due to a favorable change in the jurisdictional mix of earnings and global income tax resolutions, partially offset by the non-recurrence of tax benefits associated with certain tax initiatives.

FULL-YEAR REVENUE SUMMARY (Full-Year 2022 vs. Full-Year 2021)

Full-year 2022 revenues totaled $100.3 billion, an increase of $19.0 billion, or 23%, compared to full-year 2021, reflecting operational growth of $24.6 billion, or 30%, and an unfavorable impact of foreign exchange of $5.5 billion, or 7%. Excluding the revenue growth contributed by Paxlovid and Comirnaty ⁽¹⁾ , revenues for the full-year grew 2% operationally. Operational growth compared to the prior year was driven primarily by:

• Global sales of Paxlovid;
• Strong growth of Comirnaty ⁽¹⁾ in developed markets;
• The launch of Prevnar 20 in the U.S. for the adult population;
• Continued strong growth of Eliquis globally;
• Vyndaqel family globally, partially offset by a planned price decrease in Japan; and
• Newly acquired products Nurtec ODT/Vydura and Oxbryta,

partially offset primarily by lower revenues for:

• Comirnaty ⁽¹⁾ in emerging markets;
• Xeljanz, Chantix and Sutent globally; and
• Ibrance in developed Europe and the U.S.

RECENT NOTABLE DEVELOPMENTS (Since November 1, 2022)

Product Developments

• Comirnaty (COVID-19 vaccine, mRNA) ⁽⁹⁾
  • Clinical and Research Developments
    • In November 2022, Pfizer and BioNTech SE (BioNTech) announced updated clinical data from a Phase 2/3 clinical trial demonstrating a robust neutralizing immune response one-month after a 30-µg booster dose 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)). Immune responses against BA.4/BA.5 sublineages were substantially higher for those who received the bivalent vaccine compared to the companies' original COVID-19 vaccine, with a similar safety and tolerability profile between both vaccines.
    • In November 2022, Pfizer and BioNTech announced results from an analysis examining the immune response induced by their Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine against newer Omicron sublineages, including BA.4.6, BA.2.75.2, BQ.1.1 and XBB.1. These data were posted on the preprint server bioRxiv and indicate that the companies' bivalent vaccine elicits a greater increase in neutralizing antibody titers than the companies' original COVID-19 vaccine against these emerging Omicron sublineages.
    • In November 2022, Pfizer and BioNTech announced that the companies have initiated a Phase 1 study to evaluate the safety, tolerability and immunogenicity of a next-generation COVID-19 vaccine candidate that aims to enhance SARS-CoV-2 T cell responses and potentially broaden protection against COVID-19. This candidate, BNT162b4, is composed of a T cell antigen mRNA encoding for SARS-CoV-2 non-spike proteins that are highly conserved across a broad range of SARS-CoV-2 variants and will be evaluated in combination with the companies' Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine.
    • In December 2022, Pfizer and BioNTech announced the companies have received Fast Track Designation from the U.S. Food and Drug Administration (FDA) for their mRNA-based combination vaccine candidate for influenza and COVID-19, which aims to help prevent two respiratory diseases with a single injection. The vaccine candidate is based on BioNTech's proprietary mRNA platform technology and contains mRNA strands encoding the wild-type spike protein of SARS-CoV-2 and the spike protein of the Omicron sublineages BA.4/BA.5, as well as mRNA strands encoding the hemagglutinin of four different influenza strains, recommended for the Northern Hemisphere 2022/23 by the World Health Organization. A Phase 1 trial to examine the safety, tolerability, and immunogenicity of the combined influenza and COVID-19 candidate vaccine among healthy adults was initiated in November 2022.
  • Regulatory Developments
    • In November 2022, Pfizer and BioNTech announced the European Medicines Agency (EMA) Committee for Medicinal Products for Human Use (CHMP) recommended marketing authorization for a 10-µg booster dose of the companies' Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine (Comirnaty Original/Omicron BA.4/BA.5 5-µg/5-µg) for children 5 through 11 years of age. The recommendation was subsequently endorsed by the European Commission (EC).
    • In December 2022, Pfizer and BioNTech announced the FDA granted Emergency Use Authorization (EUA) of the companies' Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine as the third 3-µg dose in the three-dose primary series for children 6 months through 4 years of age. Children in this age group can receive a primary series consisting of two 3-µg doses of the original Pfizer-BioNTech COVID-19 vaccine followed by a third 3-µg dose of the bivalent vaccine to complete the primary series.
• Ibrance (palbociclib) -- In December 2022, the FDA expanded the indication for Ibrance to include its use in combination with an aromatase inhibitor (AI) for the treatment of HR+/HER2- metastatic breast cancer (mBC), regardless of menopausal status. The approval expands on Ibrance's existing indication for use in combination with an AI as initial endocrine-based therapy in postmenopausal women or in men, and for use with fulvestrant in patients with disease progression following endocrine therapy. Ibrance is now the only CDK 4/6 inhibitor that is FDA-approved for the treatment of HR+/HER2- mBC in combination with either an AI or fulvestrant regardless of menopausal status.
• Paxlovid (nirmatrelvir [PF-07321332] tablets and ritonavir tablets) ⁽⁹⁾
  • In November 2022, Pfizer announced an agreement with the EC to supply Paxlovid to countries participating in the Joint Procurement Agreement across Europe. This agreement is in addition to the bilateral agreements Pfizer has previously signed with 17 EU Member States and will supply participating countries up to 3.4 million treatment courses upon orders being placed. Pfizer began delivery of the initial treatment quantities ordered by the participating countries in November.
  • In December 2022, Pfizer announced it had reached an agreement with the U.S. Government for the purchase of an additional 3.7 million treatment courses of Paxlovid. This purchase supplements the 20 million treatment courses previously contracted by and already delivered to the U.S. Government. The additional 3.7 million treatment courses are planned for delivery in early 2023.
  • In December 2022, Pfizer announced the FDA has extended the review period for the New Drug Application (NDA) for Paxlovid. At the request of the FDA, Pfizer recently submitted additional analyses of efficacy and safety data from the pivotal EPIC-HR ( E valuation of P rotease I nhibition for C OVID-19 in H igh- R isk Patients) and supportive EPIC-SR ( E valuation of P rotease I nhibition for C OVID-19 in S tandard- R isk Patients) trials to be considered as part of its NDA for Paxlovid. Results from these analyses are consistent with previously disclosed efficacy and safety data for the trials. In order to allow time for a full review of the application, including the additional data analyses submitted, the FDA has extended the Prescription Drug User Fee Act (PDUFA) goal date by three months to May 2023. Pfizer submitted its original NDA seeking approval of Paxlovid in June 2022 and was granted priority review by the FDA.
  • In January 2023, Pfizer announced that the CHMP of the EMA has recommended converting the conditional Marketing Authorization for Paxlovid to standard (also referred to as "full") Marketing Authorization for the treatment of COVID-19 in adults who do not require supplemental oxygen and who are at increased risk of the disease becoming severe. The EC will review the CHMP recommendation and is soon expected to make a final decision.
• Prevnar 20 (20-valent pneumococcal conjugate vaccine) -- In January 2023, Pfizer announced that the FDA accepted for review a supplemental Biologics License Application (sBLA) for its 20-valent pneumococcal conjugate vaccine candidate for the prevention of invasive pneumococcal disease (IPD) caused by the 20 Streptococcus pneumoniae serotypes contained in the vaccine in infants and children 6 weeks through 17 years of age, and for the prevention of otitis media caused by seven of the 20 Streptococcus pneumoniae serotypes contained in the vaccine. The PDUFA goal date for a decision by the FDA is anticipated in April 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 November 2022, Pfizer announced its investigational cancer immunotherapy, elranatamab, received Breakthrough Therapy Designation from the FDA for the treatment of people with relapsed or refractory multiple myeloma (RRMM). Elranatamab is a B-cell maturation antigen (BCMA)-CD3-targeted bispecific antibody (BsAb).
  • In December 2022, Pfizer announced 10.4 month follow-up data from the pivotal Phase 2 MagnetisMM-3 clinical trial suggesting elranatamab is efficacious and has a manageable safety profile in patients with RRMM in a heavily pretreated population, who have received at least three classes of prior therapies including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody (i.e., triple-class refractory or exposed). These data were presented in an oral session at the 64th American Society of Hematology Annual Meeting and Exposition 2022. Data from the ongoing MagnetisMM-3 trial continue to be collected and will be shared as they mature.
• Etrasimod (Selective S1P Receptor Modulator) -- In December 2022, Pfizer announced that the FDA accepted for review an NDA for etrasimod for individuals living with moderately-to-severely active ulcerative colitis (UC). The FDA's decision is expected in the second half of 2023. Pfizer also announced that the EMA accepted the Marketing Authorization Application (MAA) for etrasimod in the same patient population with a decision anticipated in the first half of 2024.
• Fidanacogene elaparvovec (Hemophilia B Gene Therapy) -- In December 2022, Pfizer announced positive top-line results from the Phase 3 BENEGENE-2 study (NCT03861273) evaluating fidanacogene elaparvovec for the treatment of adult males with moderately severe to severe hemophilia B. The BENEGENE-2 study met its primary endpoint of non-inferiority and superiority in the annualized bleeding rate of total bleeds post-fidanacogene elaparvovec infusion versus prophylaxis regimen with Factor IX, administered as part of usual care. Fidanacogene elaparvovec was generally well-tolerated in the study, with a safety profile consistent with Phase 1/2 results.
• PF-06886992 (Pentavalent (MenABCWY) Meningococcal Vaccine Candidate) -- In December 2022, Pfizer announced the FDA accepted for review a Biologics License Application (BLA) for its investigational pentavalent meningococcal vaccine candidate, MenABCWY. Pfizer submitted MenABCWY for the prevention of meningococcal disease caused by the most common serogroups in individuals 10 through 25 years of age. If approved and recommended, the vaccine could help simplify the meningococcal vaccination schedule and provide the broadest serogroup coverage of any meningococcal vaccine. The PDUFA goal date for a decision by the FDA is in October 2023.
• RSVpreF (Respiratory Syncytial Virus (RSV) Bivalent Vaccine Candidate) -- In December 2022, Pfizer announced that the FDA accepted for priority review a BLA for its RSV vaccine candidate, PF-06928316 or RSVpreF, as submitted for the prevention of lower respiratory tract disease caused by RSV in individuals 60 years of age and older. The PDUFA goal date for a decision by the FDA is in May 2023.
• VLA15 (Lyme Disease Vaccine Candidate) -- In December 2022, Pfizer and Valneva SE (Valneva) reported antibody persistence data six months after the completion of a three-dose (Month 0-2-6) or a two-dose (Month 0-6) vaccination schedule with their Lyme disease vaccine candidate, VLA15, in both children and adults. The data showed antibody levels declined over time, but remained above baseline six months after completion of a three-dose (Month 0-2-6) or a two-dose (Month 0-6) vaccination schedule, with higher antibody levels observed in the three-dose vaccination schedule versus the two-dose vaccination schedule. No safety concerns were observed in the six-month observational follow-up. The three-dose vaccination schedule is being used in the Phase 3 protocols for all participants.

Corporate Developments

• In December 2022, Pfizer business executives and scientific leadership provided updates on the company's potential near-term product launches, including investigational therapies and vaccines in migraine, RSV, ulcerative colitis, alopecia, multiple myeloma and prostate cancer. Also discussed were key high-value pipeline programs around sickle cell disease, dermatomyositis, hematological malignancies, obesity and type 2 diabetes, as well as Pfizer's portfolio of mRNA vaccine candidates. If successful and approved, the company anticipates these will be key drivers of Pfizer's growth through 2030 and beyond.

• In January 2023, Pfizer announced a significant expansion of its commitment to An Accord for a Healthier World (the Accord) by offering the full portfolio of medicines and vaccines for which it has global rights on a not-for-profit basis to enable greater health for 1.2 billion people living in 45 lower-income countries. The Accord, which was first launched in May 2022, originally included only patented products available in the U.S. and EU, but now includes both patented and off-patent medicines and vaccines that treat or prevent many of the greatest infectious and non-communicable disease threats faced today in lower-income countries. As Pfizer launches new medicines and vaccines, those products will also be included in the Accord portfolio on a not-for-profit basis.

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 December 31, 2022, except for signed transactions, if any, through mid-January 2023, which are expected to give rise to acquired in-process R&D (IPR&D) expenses during fiscal 2023.
• Reflects an anticipated negative revenue impact of $0.3 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 as of mid-January 2023. Financial guidance reflects the anticipated unfavorable impact of approximately $0.2 billion on revenues and approximately $0.02 on Adjusted diluted EPS ⁽³⁾ 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 diluted EPS ⁽³⁾ 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 fourth quarter and full year for U.S. subsidiaries reflects the three and twelve months ended on December 31, 2022 and December 31, 2021, while Pfizer's fourth quarter and full year for subsidiaries operating outside the U.S. reflects the three and twelve months ended on November 30, 2022 and November 30, 2021.

(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 or indication launches. Biopharma, Pfizer's innovative science-based biopharmaceutical business, is operating under a new commercial structure which is 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) The following business development activity, among others, impacted financial results for the current or prior fiscal year:

• On October 5, 2022, Pfizer announced the completion of its acquisition of Global Blood Therapeutics, Inc. (GBT) for $68.50 per share in cash, for payments of approximately $5.3 billion, net of cash acquired, plus repayment of third-party debt of $331 million for a total net cash deployment of approximately $5.6 billion.
• On October 3, 2022, Pfizer announced the completion of its acquisition of all the outstanding shares of Biohaven Pharmaceutical Holding Company Ltd. (Biohaven) not already owned by Pfizer for $148.50 per share in cash, for payments of approximately $11.4 billion, net of cash acquired, plus repayment of third-party debt of $863 million and redemption of Biohaven's redeemable preferred stock for $495 million, for a total net cash deployment of approximately $12.7 billion. Effective immediately prior to the closing of the acquisition, Biohaven completed the spin-off of Biohaven Ltd. (NYSE: BHVN), a new company that retained Biohaven's non-calcitonin gene-related peptide (CGRP) development stage pipeline compounds. Shares of Biohaven Ltd. were distributed to Biohaven's shareholders. Pfizer, a Biohaven shareholder, received a pro rata portion of the company's shares in the distribution and currently owns approximately 1.5% of Biohaven Ltd.
• On July 18, 2022, GlaxoSmithKline plc. (GSK) completed its demerger of the Consumer Healthcare joint venture which became Haleon, an independent, publicly traded company listed on the London Stock Exchange that holds the joint Consumer Healthcare business of GSK and Pfizer following the demerger. For additional information, see Note 2C to the condensed consolidated financial statements in Pfizer's Quarterly Report on Form 10-Q for the quarterly period ended October 2, 2022.
• On June 9, 2022, Pfizer announced the completion of its acquisition of ReViral Ltd., a privately held, clinical-stage biopharmaceutical company focused on discovering, developing and commercializing novel antiviral therapeutics that target respiratory syncytial virus, for a total consideration of up to $536 million, including upfront and development milestones. In connection with the closing of the transaction, Pfizer recorded $426 million of acquired IPR&D expenses in its international third-quarter 2022.
• On March 11, 2022, Pfizer announced the completion of its acquisition of Arena Pharmaceuticals, Inc., a clinical-stage company developing innovative potential therapies for the treatment of several immuno-inflammatory diseases, for $100 per share, in cash. The total fair value of the consideration transferred was $6.6 billion ($6.2 billion, net of cash acquired), plus $138 million in payments to Arena employees for previously unvested equity compensation awards recognized as an expense, for a total net cash deployment of $6.4 billion.
• On December 31, 2021, Pfizer completed the sale of its Meridian subsidiary, the manufacturer of EpiPen and other auto-injector products, which generated approximately $300 million in annual revenues and which previously had been managed within the former Hospital therapeutic area. Beginning in the fourth quarter of 2021, the financial results of Meridian are reflected as discontinued operations for all periods presented.
• On December 24, 2021, Pfizer entered into a multi-year research collaboration with Beam Therapeutics Inc. (Beam) to utilize Beam's in vivo base editing programs, which use mRNA and lipid nanoparticles, for three targets for rare genetic diseases of the liver, muscle and central nervous system. Under the terms of the agreement, Pfizer paid Beam a $300 million upfront payment. If Pfizer elects to opt in to licenses for all three targets, Beam would be eligible for up to an additional $1.05 billion in development, regulatory and commercial milestone payments for a potential total deal consideration of up to $1.35 billion. Beam is also eligible to receive royalties on global net sales for each licensed program.
• On November 17, 2021, Pfizer acquired all outstanding shares, warrants, options and deferred shares not already owned by Pfizer of Trillium Therapeutics Inc., a clinical-stage immuno-oncology company developing therapies targeting cancer immune evasion pathways and specific cell targeting approaches, for a price of $18.50 per share in cash, for total consideration of $2.0 billion, net of cash acquired. Pfizer accounted for the transaction as an asset acquisition since the lead asset, TTI-622, represented substantially all of the fair value of the gross assets acquired. As a result, Pfizer recorded a $2.1 billion charge in fourth-quarter 2021, representing the acquired in-process R&D asset.
• On November 9, 2021, Pfizer and Biohaven announced a strategic collaboration and license agreement for Pfizer to commercialize rimegepant and zavegepant for the treatment and prevention of migraines outside of the U.S., subject to regulatory approval. Upon the closing of the transaction on January 4, 2022, Pfizer paid Biohaven $500 million, including an upfront payment of $150 million and an equity investment of $350 million. Pfizer recognized $263 million for the upfront payment and premium paid on its equity investment in acquired IPR&D expenses.
• On July 22, 2021, Arvinas Inc. (Arvinas) and Pfizer announced a global collaboration to develop and commercialize ARV-471, an investigational oral PROTAC ^® (PROteolysis TArgeting Chimera) estrogen receptor protein degrader. The estrogen receptor is a well-known disease driver in most breast cancers. Under the terms of the agreement, Pfizer paid Arvinas $650 million upfront and made a $350 million equity investment in Arvinas. Arvinas is also eligible to receive up to $400 million in approval milestones and up to $1 billion in commercial milestones. The companies will equally share worldwide development costs, commercialization expenses and profits.

(8) 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 since 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.
