EXECUTIVE COMMENTARY

Dr. Albert Bourla, Chairman and Chief Executive Officer, stated: "In the early days of the COVID-19 pandemic, we committed to use all of the resources and expertise we had at our disposal to help protect populations globally against this deadly virus, as well as to offer treatments to help avoid the worst outcomes when infections do occur. We put billions of dollars of capital on the line in pursuit of those goals, not knowing whether those investments would ever pay off. Now, less than two years since we made that commitment, we are proud to say that we have delivered both the first FDA-authorized vaccine against COVID-19 (with our partner, BioNTech) and the first FDA-authorized oral treatment for COVID-19."

Dr. Bourla continued: "These successes have not only made a positive difference in the world, but I believe they have fundamentally changed Pfizer and its culture forever. Everywhere I look in the company, I see colleagues who are inspired by what we have achieved to date and filled with determination to be part of the next breakthrough that could change the world for patients in need. As we enter a new year, I look forward to all we will accomplish together."

Frank D'Amelio, Chief Financial Officer, Executive Vice President, stated: "As I prepare to retire as CFO of Pfizer, I am proud to see that the company is performing better than at any other time during my nearly 15 years here. Today we are issuing guidance for the coming year which, if achieved, would represent the highest level of annual revenues and Adjusted diluted EPS ⁽³⁾ in Pfizer's long history. In addition, we just concluded a year where we provided tremendous value to society, including to both patients and shareholders. In 2021, we exceeded our goal of manufacturing 3 billion doses of Comirnaty ⁽¹⁾ , a monumental and unprecedented achievement by our Global Supply colleagues. Finally, we have prudently deployed our capital through multiple business development transactions in recent months to advance our strategies, always with an eye toward bolstering growth in the latter half of this decade and beyond. I have never been more confident in the future of Pfizer."

Results for the fourth quarter and full-year 2021 and 2020 ⁽⁵⁾ are summarized below.

OVERALL RESULTS

* Indicates calculation not meaningful.

REVENUES

* Indicates calculation not meaningful.

Pfizer CentreOne, the company's contract development and manufacturing organization which previously had been managed within the Hospital therapeutic area, has been moved for all periods presented into a separate operating segment to reflect the company's revised management structure which went into effect starting in the fourth quarter of 2021. Additionally, revenues and expenses associated with the former Upjohn Business ⁽⁶⁾ and Pfizer's former Meridian ⁽⁶⁾ subsidiary, the manufacturer of EpiPen and other auto-injector products, for all periods presented have been recategorized as discontinued operations and excluded from Adjusted ⁽³⁾ results.

Business development activities completed in 2020 and 2021 ⁽⁵⁾ impacted financial results in the periods presented ⁽⁶⁾ . 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⁾ .

2022 FINANCIAL GUIDANCE ⁽⁴⁾

Pfizer's 2022 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 represents 23% growth from 2021 revenues, including an expected $1.1 billion, or 1%, unfavorable impact from changes in foreign exchange rates compared to 2021.

The guidance for 2022 revenues also includes:

• an anticipated $32 billion of revenue for Comirnaty ⁽¹⁾ , which includes doses expected to be delivered in fiscal 2022 ⁽⁵⁾ under contracts signed as of late-January 2022; and
• an anticipated $22 billion of revenue for Paxlovid, which includes treatment courses expected to be delivered in fiscal 2022 ⁽⁵⁾ , primarily relating to supply contracts signed or committed as of late-January 2022.

The midpoint of the guidance range for Adjusted diluted EPS ⁽³⁾ reflects a 46% increase over 2021 actual results, including an expected $0.06, or 1%, unfavorable impact from changes in foreign exchange rates compared to 2021.

Financial guidance for Adjusted diluted EPS ⁽³⁾ is calculated using approximately 5.8 billion weighted average shares outstanding, and assumes no share repurchases in 2022. The expected increase in weighted average shares outstanding compared to 2021 of approximately 100 million shares has an unfavorable impact on 2022 Adjusted diluted EPS ⁽³⁾ of $0.10 at the midpoint of the guidance range.

CAPITAL ALLOCATION

• During full-year 2021, Pfizer paid $8.7 billion of cash dividends, or $1.56 per share of common stock, which represents an increase in dividends per share of 3% compared to full-year 2020.
• No share repurchases were completed in 2021. As of February 8, 2022, Pfizer's remaining share repurchase authorization is $5.3 billion. Current financial guidance does not reflect any share repurchases in 2022.
• Fourth-quarter 2021 diluted weighted-average shares outstanding used to calculate Reported ⁽²⁾ and Adjusted ⁽³⁾ diluted EPS was 5,768 million shares, an increase of 106 million shares, primarily due to shares issued for employee compensation programs, which resulted in a $0.01 reduction to Reported ⁽²⁾ and a $0.02 reduction to Adjusted ⁽³⁾ diluted EPS compared to the prior-year quarter.
• Full-year 2021 diluted weighted average shares outstanding was 5,708 million shares, an increase of 76 million shares, which resulted in a $0.05 reduction to Reported ⁽²⁾ and a $0.06 reduction to Adjusted ⁽³⁾ diluted EPS compared to full-year 2020.

QUARTERLY FINANCIAL HIGHLIGHTS (Fourth-Quarter 2021 vs. Fourth-Quarter 2020)

Fourth-quarter 2021 revenues totaled $23.8 billion, an increase of $12.2 billion, or 105%, compared to the prior-year quarter, reflecting operational growth of $12.3 billion, or 106%, as well as an unfavorable impact of foreign exchange of $135 million, or 1%.

Compared to the prior-year quarter, fourth-quarter 2021 revenue growth was unfavorably impacted by approximately $500 million, or 4%, as a result of fourth-quarter 2021 having four fewer selling days in the U.S. and four fewer selling days in international markets. This unfavorable impact from fewer domestic and international selling days negatively affected the growth rates of products across the entire portfolio.

Fourth-quarter 2021 operational growth was primarily driven by:

• Comirnaty ⁽¹⁾ , which contributed $12.5 billion in direct sales and alliance revenues;
• Eliquis globally, up 19% operationally, driven primarily by continued increased adoption in non-valvular atrial fibrillation and oral anti-coagulant market share gains;
• Biosimilars, which grew 30% operationally to $680 million, primarily driven by recent oncology monoclonal antibody biosimilar launches of Ruxience (rituximab), Zirabev (bevacizumab) and Trazimera (trastuzumab), as well as growth from Retacrit (epoetin) in the U.S.;
• Vyndaqel/Vyndamax globally, up 34% operationally, primarily driven by continued strong uptake of the transthyretin amyloid cardiomyopathy indication in the U.S. and Japan;
• Pfizer CentreOne, Pfizer's contract development and manufacturing organization, up 25% operationally, reflecting growth from manufacturing of legacy Upjohn products for Viatris ⁽⁶⁾ since the close of the Upjohn-Mylan transaction in November 2020 and certain Comirnaty-related manufacturing activities performed on behalf of BioNTech ⁽¹⁾ ;
• Paxlovid, which contributed $76 million in U.S. sales after the U.S. Food and Drug Administration (FDA) authorized the treatment for emergency use ⁽⁸⁾ in late-December 2021; and
• Xeljanz, up 4% operationally, driven primarily by favorable wholesaler inventory buying patterns in the U.S., as well as growth in the emerging markets from the rheumatoid arthritis indication,

partially offset primarily by lower revenues for:

• Prevnar family (Prevnar/Prevenar 13 & 20) globally, down 25% operationally, driven by:
  • a 27% decline in the U.S. primarily due to unfavorable timing of government purchases for the pediatric indication and disruptions to healthcare activity related to COVID-19, including the prioritization of primary and booster vaccination campaigns for COVID-19, as well as the continued impact of a lower remaining unvaccinated eligible adult population, and
  • a 24% operational decline outside the U.S. primarily due to the impact of increased adult uptake in the prior-year period from greater vaccine awareness for respiratory illnesses;
• Chantix globally, which continues to be negatively impacted by the ongoing global pause in shipments of Chantix due to the presence of N-nitroso-varenicline above an acceptable level of intake set by various global regulators, the ultimate timing for resolution of which may vary by country, combined with returns of product sold in previous periods;
• Ibrance in the U.S., down 7%, primarily reflecting an increase in the proportion of patients accessing Ibrance through Pfizer's Patient Assistance Program compared to the prior-year quarter;
• Sutent globally, down 32% operationally, primarily reflecting lower volume demand in the U.S. resulting from its loss of exclusivity in August 2021; and
• Premarin in the U.S., down 31%, primarily driven by unfavorable changes in formulary coverage and temporary supply shortages of certain formulations of Premarin.

GAAP Reported ⁽²⁾ Income Statement Highlights

SELECTED REPORTED COSTS AND EXPENSES ⁽²⁾

* Indicates calculation not meaningful.

Fourth-quarter 2021 Cost of Sales ⁽²⁾ as a percentage of revenues increased 16.2 percentage points compared with the prior-year quarter. The drivers for the increase include, among other things:

• an increase of approximately 20 percentage points associated with sales of Comirnaty ⁽¹⁾ , which includes a charge for the 50% gross profit split with BioNTech and applicable royalty expenses,

partially offset by:

• net favorable changes in the sales mix of other products, including the impact of higher alliance revenues.

SI&A Expenses ⁽²⁾ increased 10% operationally in fourth-quarter 2021 compared with the prior-year quarter, primarily driven by increased product-related spending across multiple therapeutic areas, including costs related to Comirnaty, driven by a higher provision for healthcare reform fees based on sales.

Fourth-quarter 2021 R&D Expenses ⁽²⁾ increased 77% operationally compared with the prior-year quarter, primarily reflecting a $2.1 billion charge for in-process research and development (IPR&D) expense associated with the acquisition of Trillium Therapeutics Inc., which closed in fourth-quarter 2021, as well as up-front payments of $300 million and $50 million related to collaboration agreements signed in the fourth quarter with Beam Therapeutics, Inc. and BioNTech, respectively. Growth compared to the prior-year quarter was also driven by increased investments across multiple late-stage clinical programs, including additional spending related to the development of the oral COVID-19 treatment program.

Pfizer recorded $835 million of other income––net ⁽²⁾ in fourth-quarter 2021 compared with $102 million of other deductions––net ⁽²⁾ in fourth-quarter 2020. The period-over-period change was primarily driven by:

• lower asset impairment charges incurred in fourth-quarter 2021 compared to fourth-quarter 2020;
• an increase in net periodic benefit credits recorded in fourth-quarter 2021, primarily resulting from pension plan actuarial remeasurement gains; and
• the non-recurrence of certain losses on asset disposals in the prior-year quarter,

partially offset by:

• net losses on equity securities in fourth-quarter 2021 versus net gains on equity securities recognized in the prior-year quarter.

Pfizer's effective tax rate on Reported income ⁽²⁾ for fourth-quarter 2021 increased compared to the prior-year quarter due to the change in the jurisdictional mix of earnings primarily related to Comirnaty and the non-recurrence of tax benefits associated with certain intangible asset impairments.

FULL-YEAR REVENUE SUMMARY (Full-Year 2021 vs. Full-Year 2020)

Full-year 2021 revenues totaled $81.3 billion, an increase of $39.6 billion, or 95%, compared to full-year 2020, reflecting operational growth of $38.4 billion, or 92%, and the favorable impact of foreign exchange of $1.2 billion, or 3%. Excluding the revenue contributions of Comirnaty ⁽¹⁾ and Paxlovid, revenues for the full year grew 6% operationally. Operational growth compared to the prior year was driven primarily by:

• Global sales of Comirnaty;
• Strong growth of Eliquis globally;
• Oncology biosimilars, driven by growth following the launches of Ruxience, Zirabev and Trazimera;
• Pfizer CentreOne, led by manufacturing of legacy Upjohn products for Viatris and Comirnaty for BioNTech;
• Vyndaqel/Vyndamax in the U.S., developed Europe and Japan;
• the Hospital therapeutic area, primarily driven by the anti-infectives portfolio in international markets;
• Inlyta globally; and
• Xtandi in the U.S.,

partially offset primarily by lower revenues for:

• Prevnar/Prevenar 13 and Chantix globally;
• Enbrel outside the U.S.; and
• Sutent in developed markets.

RECENT NOTABLE DEVELOPMENTS (Since November 2, 2021)

Product Developments

• Cibinqo (abrocitinib)
  • In December 2021, Pfizer announced that the European Commission (EC) approved the 100 mg and 200 mg doses of Cibinqo, an oral, once-daily, Janus kinase 1 (JAK1) inhibitor, for the treatment of moderate-to-severe atopic dermatitis (AD) in adults who are candidates for systemic therapy. Additionally, a 50 mg dose was approved to treat moderate-to-severe AD specifically in patients with moderate and severe renal impairment (kidney failure) or certain patients receiving treatment with inhibitors of cytochrome P450 (CYP) 2C19.
  • In January 2022, Pfizer announced that the FDA approved Cibinqo for the treatment of adults living with refractory, moderate-to-severe AD whose disease is not adequately controlled with other systemic drug products, including biologics, or when use of those therapies is inadvisable. Cibinqo is approved at the recommended doses of 100 mg and 200 mg, with the 200 mg dose being recommended for patients who are not responding to the 100 mg dose. Additionally, a 50 mg dose was approved to treat moderate-to-severe AD specifically in patients with moderate renal impairment (kidney failure), certain patients receiving treatment with inhibitors of cytochrome P450 (CYP) 2C19, or patients who are known or suspected to be poor metabolizers of CYP2C19. For patients with moderate renal impairment who are not responding to 50 mg once daily, 100 mg once daily may also be prescribed.
• Bavencio (avelumab) -- Today, Pfizer and Merck KGaA, Darmstadt, Germany are providing an update on the Phase 3 JAVELIN Lung 100 trial, which assessed the safety and efficacy of two dosing regimens of avelumab monotherapy compared with platinum-based doublet chemotherapy as first-line treatment in patients with metastatic non-small cell lung cancer (NSCLC) whose tumors express PD-L1. While avelumab showed clinical activity in this population, the study did not meet the primary endpoints of overall survival and progression-free survival in the high PD-L1+ population for either of the avelumab dosing regimens evaluated. The safety profile for avelumab in this trial was consistent with that observed in the overall JAVELIN clinical development program. Avelumab is not approved for the treatment of any patients with NSCLC. The outcome of the JAVELIN Lung 100 trial has no bearing on any of avelumab's currently-approved indications. Full results of the study will be shared at a future date.
• Comirnaty (BNT162b2, COVID-19 Vaccine, mRNA)
  • Clinical and Research Developments
    • In November 2021, Pfizer and BioNTech announced topline results from a longer-term analysis of the safety and efficacy of Comirnaty in individuals 12 through 15 years of age. The updated findings from the companies' pivotal Phase 3 trial show that a two-dose series of Comirnaty (30 µg per dose) was 100% effective against COVID-19, measured seven days through over four months after the second dose. The adverse event profile was generally consistent with other clinical safety data for Comirnaty.
    • In December 2021, Pfizer and BioNTech announced results from an initial laboratory study demonstrating that serum antibodies induced by Comirnaty neutralize the SARS-CoV-2 Omicron variant after three doses. Sera obtained from vaccinees one month after receiving the booster vaccination (third dose of BNT162b2 vaccine) neutralized the Omicron variant to levels that are comparable to those observed for the wild-type SARS-CoV-2 spike protein after two doses. Preliminary data showed that a third dose of Comirnaty increased the neutralizing antibody titers against the Omicron strain spike by 25-fold compared to two doses.
    • In December 2021, Pfizer and BioNTech shared that following a routine review by the external independent Data Monitoring Committee (DMC), the companies will amend the clinical study evaluating the safety, tolerability, and immunogenicity of two 3 µg doses of BNT162b2 in children 6 months to under 5 years of age. Compared to the 16- to 25-year-old population in which high efficacy was demonstrated, non-inferiority was met for the 6- to 24-month-old population but not for the 2- to under 5-year-old population in this analysis. The study, which is ongoing and remains blinded, will now include evaluating a third dose of 3 µg at least two months after the second dose of the two-dose series to provide high levels of protection in this young age group. Pfizer and BioNTech also plan to evaluate a third dose of the 10 µg formulation in children 5 to under 12 years of age.
    • In January 2022, Pfizer and BioNTech announced the initiation of a clinical study to evaluate the safety, tolerability and immunogenicity of an Omicron-based vaccine candidate in healthy adults 18 through 55 years of age. The study will have three cohorts examining different regimens of the current Pfizer-BioNTech COVID-19 vaccine or an Omicron-based vaccine. The study will draw upon some participants from the companies' Phase 3 COVID-19 booster study and is part of their ongoing efforts to address Omicron and determine the potential need for variant-based vaccines.
  • Regulatory Developments
    • In November 2021, Pfizer and BioNTech announced that the FDA expanded the emergency use ⁽⁸⁾ authorization (EUA) for a booster dose of Comirnaty to include individuals 18 years of age and older. Similarly, in December 2021, the FDA authorized for emergency use ⁽⁸⁾ a booster dose for individuals 16 years of age and older. The booster dose is the same dosage strength (30 μg) as the doses in the primary series.
    • In November 2021, Pfizer and BioNTech announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) issued a positive opinion on the administration of two 10 µg doses of Comirnaty in children 5 to under 12 years of age. The EC subsequently approved an extension to the Conditional Marketing Authorisation (CMA) to include this additional age group.
    • In December 2021, Pfizer and BioNTech announced they have submitted a supplemental Biologics License Application (sBLA) to the FDA to expand the approval of Comirnaty to include individuals ages 12 through 15 years of age. The sBLA includes updated longer-term follow-up data from the companies' pivotal Phase 3 clinical trial of 2,228 participants 12 through 15 years of age. Later in December 2021, the companies announced submission of these data to the EMA to further support the favorable safety and efficacy profile of Comirnaty in this age group. The companies have also submitted the data to other regulatory authorities around the world.
    • In January 2022, Pfizer and BioNTech announced that the FDA expanded the EUA ⁽⁸⁾ for a booster dose of Comirnaty to include individuals 12 years of age and older. The booster dose is the same dosage strength (30 μg) as the dose approved in the primary series. Additionally, the FDA amended the existing EUA to reduce the time for administration of a booster dose from at least six months to at least five months following completion of the primary series for individuals 12 years of age and older and expanded the current EUA to include administration of a third primary series dose at least 28 days following the second dose for individuals 5 through 11 years of age who have been determined to have certain kinds of immunocompromise.
    • In February 2022, Pfizer and BioNTech announced that, following a request from the FDA, the companies have initiated a rolling submission seeking to amend the EUA of Comirnaty to include children 6 months through 4 years of age, in response to the urgent public health need in this population. This application is for authorization of two 3 µg doses of BNT16262 in this age group. Data on a third dose given at least 8 weeks after completion of the second dose are expected in the coming months and will be submitted to the FDA to support a potential expansion of this requested EUA.
  • Commercial Developments
    • In December 2021, Pfizer and BioNTech announced the EC exercised an option to purchase more than 200 million additional doses of Comirnaty. These optional doses are in addition to the 450 million doses already planned to be delivered in 2022 based on previously signed agreements, bringing the total number of vaccine doses to be delivered to the EC member states in 2022 to more than 650 million.
• Lorbrena (lorlatinib) -- In January 2022, Pfizer announced that the EC granted marketing authorization for Lorviqua (available in the U.S. under the brand name Lorbrena) as monotherapy for the treatment of adult patients with anaplastic lymphoma kinase (ALK)-positive advanced NSCLC previously not treated with an ALK inhibitor. The approval follows a positive opinion from the EMA's CHMP in December 2021 and was based on results from the Phase 3 CROWN trial, showing Lorviqua reduced risk of disease progression or death by 72% in newly-diagnosed individuals compared to Xalkori.
• Paxlovid (nirmatrelvir [PF-07321332] tablets and ritonavir tablets)
  • Clinical and Research Developments
    • In November 2021, Pfizer announced positive topline results from an interim analysis of 1,219 adults enrolled in the Phase 2/3 EPIC-HR ( E valuation of P rotease I nhibition for C OVID-19 in H igh- R isk Patients) randomized, double-blind study of non-hospitalized adult patients with COVID-19, who are at high risk of progressing to severe illness. The scheduled interim analysis showed an 89% reduction in risk of COVID-19-related hospitalization or death from any cause compared to placebo in patients treated within three days of symptom onset. Similar risk reductions were observed in patients treated within five days of symptom onset. Treatment-emergent adverse events were comparable between Paxlovid and placebo, most of which were mild in intensity.
    • In December 2021, Pfizer announced final results from an analysis of all 2,246 adults enrolled in the EPIC-HR trial. The results were consistent with the interim analysis announced in November 2021, showing Paxlovid significantly reduced the risk of hospitalization or death for any cause by 89% compared to placebo in non-hospitalized, high-risk adult patients with COVID-19 treated within three days of symptom onset. Paxlovid reduced the risk of hospitalization or death for any cause by 88% in patients treated within five days of symptom onset.
    • In December 2021, Pfizer announced results of an interim analysis of the EPIC-SR ( E valuation of P rotease I nhibition for C OVID-19 in S tandard- R isk Patients) Phase 2/3 study, which included unvaccinated adults who were at a low risk of hospitalization or death as well as vaccinated adults who had one or more risk factors for progressing to severe illness, showing that the novel primary endpoint of self-reported, sustained alleviation of all symptoms for four consecutive days, as compared to placebo, was not met. The key secondary endpoint showed a 70% reduction in hospitalization and no deaths in the treated population for any cause compared to placebo. Additionally, there was approximately a 10-fold decrease in viral load compared to placebo, consistent with results from the EPIC-HR study. Based on the totality of the data, the independent DMC recommended that the trial continue. Enrollment will be re-opened to increase the study's sample size and allow for a more complete assessment of these data.
    • In January 2022, Pfizer shared results from multiple studies demonstrating that the in vitro efficacy of nirmatrelvir, the active main protease inhibitor of Paxlovid, is maintained against the SARS-CoV-2 variant Omicron. Taken together, these in vitro studies suggest that Paxlovid has the potential to maintain plasma concentrations many-fold times higher than the amount required to prevent Omicron from replicating in cells.
  • Regulatory Developments
    • In December 2021, Pfizer announced that the FDA authorized Paxlovid for emergency use ⁽⁸⁾ 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 [88 lbs]) with positive results of direct SARS-CoV-2 viral testing, and who are at high risk for progression to severe COVID-19, including hospitalization or death. Pfizer plans to file a New Drug Application (NDA) with the FDA for potential full regulatory approval in 2022.
    • In January 2022, Pfizer announced that the EMA's CHMP issued a positive opinion recommending the CMA of Paxlovid for the treatment of COVID-19 in adults who do not require supplemental oxygen and who are at increased risk for progressing to severe COVID-19, and the EC granted that CMA the day after the CHMP issued its opinion. In December 2021, the CHMP had issued advice under Article 5(3) of Regulation 726/2004 to support authorities of European Union (EU) member states regarding the potential supply and use of Paxlovid in the EU prior to the CMA decision.
  • Commercial Developments
    • In November 2021, Pfizer and the Medicines Patent Pool (MPP) announced the signing of a voluntary non-exclusive license agreement for Paxlovid. Under the terms of the agreement, MPP can grant sublicenses to qualified generic medicine manufacturers worldwide to manufacture and supply Paxlovid to 95 countries, covering up to approximately 53% of the world's population. Pfizer will not receive royalties on sales in low-income countries and will further waive royalties on sales in all countries covered by the agreement while COVID-19 remains classified as a Public Health Emergency of International Concern by the World Health Organization.
    • In November 2021, Pfizer announced an agreement with the U.S. government to supply 10 million treatment courses of Paxlovid for a total purchase price of approximately $5.3 billion. In January 2022, the U.S. government committed to purchase an additional 10 million treatment courses of Paxlovid, bringing the total number to 20 million. Approximately 10 million Paxlovid treatment courses are expected to be delivered to the U.S. by the end of June 2022, with the remaining 10 million expected to follow by the end of September 2022.
    • In December 2021, Pfizer announced an agreement with the United Kingdom (U.K.) government to supply an additional 2.5 million treatment courses of Paxlovid. This is in addition to the 250,000 treatment courses previously contracted by the U.K. government. A total of 2.75 million courses are expected to be delivered to the U.K. through 2022.
    • In December 2021, Pfizer announced that it plans to manufacture up to 120 million treatment courses of Paxlovid by the end of 2022, depending on the global need, which will be driven by advance purchase agreements, with 30 million courses expected to be produced in the first half of 2022 and the remaining 90 million courses expected to be produced in the second half of 2022.
• Prevnar 20 (pneumococcal 20-valent conjugate vaccine)
  • In December 2021, Pfizer announced that the CHMP of the EMA issued a positive opinion recommending the granting of a marketing authorization for the Company's pneumococcal 20-valent conjugate vaccine for the prevention of invasive disease and pneumonia caused by 20 Streptococcus pneumoniae (pneumococcus) serotypes in adults ages 18 years and older. The decision on whether to approve the vaccine, whose EU trade name will be Apexxnar, will be made by the EC and will be applicable to all 27 EU member states plus Iceland, Lichtenstein and Norway.
  • In January 2022, Pfizer announced positive topline results from a Phase 3 study describing the safety and immunogenicity of Prevnar 20 in adults 65 years of age or older when administered at the same time as Comirnaty or when each vaccine was given with placebo. Responses elicited by Prevnar 20 for all 20 serotypes were similar whether given with a dose of Comirnaty or with placebo. Responses to a booster dose of Comirnaty were also similar when given with Prevnar 20 or given with placebo. The safety profile of co-administering Prevnar 20 with a booster dose of Comirnaty generally reflected that observed with a Comirnaty booster dose.
• Xeljanz (tofacitinib)
  • In November 2021, Pfizer announced EC approval of Xeljanz 5 mg twice daily for the treatment of adults with active ankylosing spondylitis (AS) who have responded inadequately to conventional therapy.
  • In December 2021, Pfizer announced revisions to the U.S. Prescribing Information for Xeljanz/Xeljanz XR/Xeljanz Oral Solution to include a new boxed warning for major adverse cardiovascular events (MACE) and updated boxed warnings regarding mortality, malignancies and thrombosis (with corresponding updates to applicable warnings and precautions), following the completion of the FDA's review of the ORAL Surveillance trial. In addition, indications for the treatment of adults with moderately to severely active rheumatoid arthritis (RA) or active psoriatic arthritis (PsA), and patients who are two years of age and older with active polyarticular course juvenile idiopathic arthritis (pcJIA) have been revised; Xeljanz is now indicated in patients who have had inadequate response or intolerance to one or more tumor necrosis factor (TNF) blockers.
  • In December 2021, Pfizer announced FDA approval of a supplemental New Drug Application (sNDA) for Xeljanz/Xeljanz XR for the treatment of adults with active AS who have had an inadequate response or intolerance to one or more TNF blockers. Xeljanz is the first and only JAK inhibitor approved for five indications in the U.S. for the treatment of patients with certain immuno-inflammatory conditions.
• Vyndaqel (tafamidis) -- In December 2021, Pfizer announced publication of a post-hoc, interim analysis that showed treatment with Vyndaqel/Vyndamax reduced the risk of all-cause mortality at five years, providing a clinically significant survival benefit for patients with transthyretin amyloid cardiomyopathy (ATTR-CM). The analysis from the Phase 3 Transthyretin Amyloid Cardiomyopathy Clinical Trial (ATTR-ACT) and its long-term extension (LTE) study was published in Circulation: Heart Failure .

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.

• ARV-471 -- In December 2021, Arvinas Inc. and Pfizer announced an update on Phase 1 dose escalation data of ARV-471, a novel PROTAC estrogen receptor (ER) degrader being co-developed for the treatment of patients with locally advanced or metastatic ER-positive/human epidermal growth factor receptor 2 (HER2)-negative breast cancer (ER+/HER2-). The data were presented at the 2021 San Antonio Breast Cancer Symposium (SABCS) and further validate the evaluation of ARV-471 as a potential treatment for metastatic breast cancer that is ongoing in a Phase 1b combination study with Ibrance (palbociclib) and a Phase 2 monotherapy dose expansion study.
• Fordadistrogene movaparvovec (Duchenne Muscular Dystrophy (DMD) Gene Therapy) -- In December 2021, Pfizer informed the DMD community and the public that a participant in the non-ambulatory cohort of its Phase 1b trial of fordadistrogene movaparvovec had passed away. Screening, randomization and dosing have been paused in all trials of fordadistrogene movaparvovec, including the Phase 3 CIFFREO study in ambulatory participants, while the independent external DMC reviews the data. The safety and well-being of patients is Pfizer's top priority, and it remains committed to the DMD community. Pfizer will share additional information through the appropriate channels once a full assessment can be completed.
• Giroctocogene fitelparvovec (Hemophilia A Gene Therapy)
  • In December 2021, Pfizer and Sangamo Therapeutics, Inc. announced updated follow-up data from the Phase 1/2 Alta study of giroctocogene fitelparvovec, an investigational gene therapy for patients with moderately severe to severe hemophilia A. At 104 weeks, the five patients in the highest dose 3e13 vg/kg cohort had mean factor VIII (FVIII) activity of 25.4% via chromogenic clotting assay. In this cohort, mean annualized bleeding rate (ABR) was 0.0 in the first year post-infusion and was 1.4 throughout the total duration of follow-up as of the October 1, 2021 cutoff date. All bleeding events occurred after week 69 post-infusion. Two patients experienced bleeding events necessitating treatment with exogenous FVIII. No participants in the highest dose cohort have resumed prophylaxis.
  • The Phase 3 AFFINE clinical trial of giroctocogene fitelparvovec in patients with hemophilia A has started and is over 50% enrolled. Following the observation of FVIII levels greater than 150% in some treated patients, Pfizer voluntarily paused screening and dosing of additional patients in the trial to implement a protocol amendment to provide clinical management guidance for elevated FVIII levels. Subsequently, on November 3, 2021, the FDA informed Pfizer that this trial has been placed on clinical hold while the protocol amendment and associated documents are reviewed. A protocol amendment and associated documents are in the process of being submitted to health authorities in the countries where the trial is being conducted and a response is being prepared to the FDA clinical hold. Pfizer hopes to obtain agreements to proceed and begin to reopen trial sites in the first half of 2022.
• PF-07304814 (Intravenous Protease Inhibitor for COVID-19) -- In February 2022, Pfizer discontinued the global clinical development program for PF-07304814, an intravenously administered SARS-CoV-2 main protease (Mpro) inhibitor being evaluated in adults hospitalized with severe COVID-19. This decision was made based on a totality of information, including a careful review of early data and a thorough assessment of the candidate's potential to successfully fulfill patient needs. Dosing of PF-07304814 in the National Institutes of Health's (NIH) ongoing ACTIV-3 study has ceased.
• Somatrogon (MOD-4023)
  • In December 2021, Pfizer announced that the CHMP of the EMA adopted a positive opinion recommending somatrogon, Pfizer's and OPKO Health, Inc.'s once-weekly long-acting recombinant human growth hormone, for marketing authorization to treat children and adolescents from 3 years of age with growth disturbance due to insufficient secretion of growth hormone. A decision from the EC is expected in early 2022.
  • In January 2022, Pfizer and OPKO Health, Inc. announced that the FDA issued a Complete Response Letter (CRL) for the Biologics License Application (BLA) for somatrogon. Pfizer is evaluating the CRL and will work with the FDA to determine an appropriate path forward in the U.S. Somatrogon had previously received regulatory approvals in Canada, Australia and Japan.
• VLA15 (Lyme Disease Vaccine Candidate) -- In February 2022, Valneva SE (Valneva) and Pfizer reported further positive Phase 2 data for their Lyme disease vaccine candidate, VLA15. Based on these new results, Valneva and Pfizer plan to proceed with a three-dose primary series vaccination schedule in a planned Phase 3 clinical trial. The trial will evaluate VLA15 in adults and pediatric subjects 5 years of age and above and is expected to be initiated in 2022, subject to regulatory approval.
• Vupanorsen (PF-07285557)
  • In November 2021, Pfizer announced topline results from the Phase 2b study of vupanorsen, an investigational antisense therapy being developed for potential indications in cardiovascular (CV) risk reduction and severe hypertriglyceridemia (SHTG). In the study, vupanorsen had a statistically significant effect in lowering non-high density lipoprotein cholesterol (non-HDL-C), triglycerides (TG) and angiopoietin-like 3 (ANGPTL3) at all dose levels at 24 weeks, compared to placebo. Apolipoprotein B (ApoB) and low-density lipoprotein cholesterol (LDL-C) were significantly reduced by some (but not all) doses of vupanorsen. Full results from the TRANSLATE-TIMI 70 study will be submitted for future scientific publication and presentation.
  • In January 2022, Pfizer announced the discontinuation of the Pfizer-led clinical development program for vupanorsen. The decision was made after a thorough review of data from the Phase 2b TRANSLATE-TIMI 70 study. While vupanorsen demonstrated a statistically significant effect in the trial, the magnitude of non-HDL-C and TG reduction observed did not support continuation of the clinical development program for CV risk reduction and SHTG. Vupanorsen was also associated with dose-dependent increases in liver fat, and higher doses were associated with elevations in the liver enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Pfizer will return development rights to vupanorsen to Ionis Pharmaceuticals, Inc., from which it licensed the investigational therapy in a worldwide exclusive agreement in November 2019.

(Note: If clicking on the above link does not open up a new web page, you may need to cut and paste the above URL into your browser's address bar.)

For additional details, see the attached financial schedules and product revenue tables attached to the press release located at the hyperlink referred to above and the attached disclosure notice.

(1) Comirnaty includes direct sales and alliance revenues related to sales of the Pfizer-BioNTech SE (BioNTech) COVID-19 vaccine, which are recorded within Pfizer's Vaccines therapeutic area. 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 $46 million and $320 million for the fourth-quarter and full-year 2021, respectively.

(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. 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 EPS attributable to Pfizer Inc. common shareholders—diluted before the impact of purchase accounting for acquisitions, acquisition-related items, discontinued operations and certain significant items. Adjusted cost of sales, Adjusted selling, informational and administrative (SI&A) expenses, Adjusted research and development (R&D) expenses and Adjusted other (income)/deductions are income statement line items prepared on the same basis as, and therefore components of, the overall Adjusted income measure. See the accompanying reconciliations of certain GAAP Reported to Non-GAAP Adjusted information for fourth-quarter and full-year 2021 and 2020. 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 2020 Annual Report on Form 10-K and the accompanying Non-GAAP Financial Measure: Adjusted Income section of this press release for additional information.

(4) Pfizer does not provide guidance for 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 pending litigation, unusual gains and losses, acquisition-related expenses, gains and losses from equity securities, actuarial gains and losses from pension and postretirement plan remeasurements and potential future asset impairments 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 2022 reflects the following:

• Does not assume the completion of any business development transactions not completed as of December 31, 2021, including any one-time upfront payments associated with such transactions.
• Includes Pfizer's pro rata share of the Consumer Healthcare joint venture anticipated earnings, which is recorded in Adjusted other (income)/deductions ⁽³⁾ on a one-quarter lag, and assumes no changes to Pfizer's 32% ownership stake in the joint venture in 2022.
• Includes an estimated benefit of approximately $0.06 on Adjusted diluted EPS ⁽³⁾ resulting from a change in policy for intangible amortization expense to begin excluding all amortization of intangibles from Adjusted income ⁽³⁾ compared to excluding only amortization of intangibles related to large mergers or acquisitions under the prior methodology. This change was effective beginning in the first quarter of 2022 and will require recasting prior period amounts to conform to the new policy.
• Reflects an anticipated negative revenue impact of $0.7 billion due to recent and expected generic and biosimilar competition for certain products that have recently lost or are anticipated to soon lose patent protection.
• Exchange rates assumed are as of mid-January 2022. Financial guidance reflects the anticipated unfavorable impact of approximately $1.1 billion on revenues and approximately $0.06 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 2021.
• Guidance for Adjusted diluted EPS ⁽³⁾ assumes diluted weighted-average shares outstanding of approximately 5.8 billion shares, which assumes no share repurchases in 2022.

(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, 2021 and December 31, 2020, 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, 2021 and November 30, 2020.

(6) The following business development activity, among others, impacted financial results for the periods presented:

• 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 Hospital therapeutic area. Beginning in the fourth quarter of 2021, the financial results of Meridian are reflected as discontinued operations for all periods presented. In connection with the sale, Pfizer recognized an after-tax loss of approximately $167 million in discontinued operations.
• 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. (Trillium), 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 to R&D expenses, representing the acquired in-process R&D asset.
• 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.
• On November 16, 2020, Pfizer completed the transaction to spin off its Upjohn Business and combine it with Mylan N.V. (Mylan) to form Viatris Inc. (Viatris). On December 21, 2020, Pfizer and Viatris completed the termination of a pre-existing strategic collaboration between Pfizer and Mylan for generic drugs in Japan (Mylan-Japan collaboration) and Pfizer transferred related operations that were part of the Mylan-Japan collaboration to Viatris. As a result of the spin-off of the Upjohn Business and the termination of the Mylan-Japan collaboration, the results of operations of the Upjohn Business and the Mylan-Japan collaboration are presented as discontinued operations.
• On April 9, 2020, Pfizer signed a global agreement with BioNTech to co-develop a first-in-class, mRNA-based coronavirus vaccine program, BNT162, aimed at preventing COVID-19 infection. In connection with the agreement, Pfizer paid BioNTech an upfront cash payment of $72 million in second-quarter 2020. Pfizer also made an equity investment of $113 million in BioNTech common stock. Pfizer made an additional investment of $50 million in common stock of BioNTech as part of an underwritten equity offering by BioNTech, which closed in July 2020. On January 29, 2021, Pfizer and BioNTech signed an amended version of the April 2020 agreement. Under the January 2021 agreement, BioNTech paid Pfizer its 50 percent share of prior development costs in a lump sum payment during the first quarter of 2021. Further R&D costs are being shared equally.

(7) References to operational variances in this press release pertain to period-over-period growth rates 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.

(8) Emergency uses of the Pfizer-BioNTech COVID-19 Vaccine and Paxlovid have not been approved or licensed by the FDA. Emergency uses of Comirnaty have been authorized by the FDA, under an Emergency Use Authorization (EUA) to prevent Coronavirus Disease 2019 (COVID-19) in individuals 5 years of age and older. Comirnaty is licensed by the FDA for individuals 16 years of age and older. In addition, Comirnaty is under EUA for individuals ages 12 through 15, a third dose for certain immunocompromised individuals 5 years of age and older, and a booster dose for individuals 12 years of age and older. 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 [88 lbs]) with positive results of direct SARS-CoV-2 viral testing, and who are at high-risk for progression to severe COVID-19, including hospitalization or death. 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 under Section 564(b)(1) of the FD&C Act unless the declaration is terminated or authorization revoked sooner.
