Pfizer Inc. (NYSE: PFE) reported financial results for first-quarter 2021 and raised 2021 guidance⁽³⁾ for revenues and Adjusted diluted EPS⁽²⁾ driven by the updated expectations for contributions to 2021 performance from BNT162b2, the Pfizer-BioNTech SE (BioNTech) COVID-19 vaccine, as well as the strong performance of the business excluding BNT162b2, partially offset by anticipated additional R&D investments into vaccines to protect against COVID-19, as well as other mRNA-based development programs and COVID-19 antivirals.

Additionally, Pfizer published this morning on its website the first-quarter 2021 earnings presentation and accompanying prepared remarks from management.

EXECUTIVE COMMENTARY

Dr. Albert Bourla, Chairman and Chief Executive Officer, stated: “I am extremely proud of the way we have begun 2021, delivering strong financial results in the first quarter. Even excluding the growth provided from BNT162b2, our revenues grew 8% operationally, which aligns with our stated goal of delivering at least a 6% compound annual growth rate through 2025. In addition, we have achieved important clinical, regulatory and commercial milestones across our pipeline and portfolio while also continuing to increase our capacity to supply urgently-needed doses of BNT162b2 to the world. Each of these accomplishments further demonstrates our commitment to Pfizer’s purpose: Breakthroughs that change patients’ lives.”

Frank D’Amelio, Chief Financial Officer and Executive Vice President, Global Supply, stated: “I am very happy with the performance of all of our therapeutic areas this quarter. Multiple innovative and biosimilar products across our portfolio delivered growth, demonstrating the strength of our business and the depth and breadth of our growth drivers. I am also pleased with our recent announcement that we will maintain our dividend for second-quarter 2021 at the current level, even after Viatris begins paying its dividend. This will make 2021 the 12th year in a row with a dividend increase. I remain confident in Pfizer’s ability to continue to deliver on our commitments to our patients and shareholders in 2021 and beyond.”

Results for the first quarter of 2021 and 2020⁽⁵⁾ are summarized below.

OVERALL RESULTS

REVENUES

Following the completion of the spin-off of the Upjohn Business⁽⁴⁾ in the fourth quarter of 2020, Pfizer now operates as a focused innovative biopharmaceutical company engaged in the discovery, development, manufacturing, marketing, sales and distribution of biopharmaceutical products worldwide.

Revenues and expenses associated with the Upjohn Business⁽⁴⁾ for first-quarter 2020 have been recategorized as discontinued operations and excluded from Adjusted⁽²⁾ results. Pfizer’s Meridian subsidiary, the manufacturer of EpiPen and other auto-injector products, which had been reported within the results of the Upjohn Business⁽⁴⁾ in the first three quarters of 2020_, is now included within the Hospital therapeutic area for all periods presented.

Business development activities completed in 2020 and 2021 impacted financial results in the periods presented⁽⁴⁾. 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⁽⁶⁾.

2021 FINANCIAL GUIDANCE⁽³⁾

Financial guidance reflects management’s current expectations for operational performance, foreign exchange rates and management’s current projections as to the severity, duration and global macroeconomic impact of the COVID-19 pandemic.

Key guidance assumptions included in these projections broadly reflect a continued recovery in macroeconomic and healthcare activity throughout 2021 as more of the population becomes vaccinated against COVID-19. These assumptions are guided by the trajectory of current infection rates in many parts of the world and the expected timeline for broad access to effective vaccines.

Pfizer is raising its guidance ranges for revenues, Adjusted cost of sales⁽²⁾ as a percentage of revenues, Adjusted R&D expenses⁽²⁾ and Adjusted diluted EPS⁽²⁾ to reflect the updated expectations for contributions to 2021 performance from BNT162b2 and the continued strong performance of the business excluding BNT162b2, partially offset by anticipated additional R&D investments into vaccines to protect against COVID-19, as well as early research investments into other mRNA-based development programs and COVID-19 antivirals. Current 2021 financial guidance is presented below.

The midpoint of the guidance range for revenues represents 71% growth from 2020 revenues, including an expected $1.3 billion, or 3%, favorable impact from changes in foreign exchange rates. The midpoint of the updated guidance range for Adjusted diluted EPS⁽²⁾ reflects a 59% increase over 2020 actual results, including an expected $0.09, or 4%, benefit due to favorable changes in foreign exchange rates.

Financial guidance for Adjusted diluted EPS⁽²⁾ is calculated using approximately 5.7 billion weighted average shares outstanding, and does not currently assume any share repurchases in 2021.

Update to Assumptions Related to BNT162b2 Within Guidance

Due to additional supply agreements that have been signed since the previous guidance release, Pfizer is updating the revenue assumptions related to BNT162b2 incorporated within the above guidance ranges. The updated assumptions are summarized below.

The BNT162b2 revenue projection incorporated within Pfizer’s 2021 financial guidance includes 1.6 billion doses that are expected to be delivered in 2021 under contracts that have been signed through mid-April 2021. This guidance may be adjusted in the future as additional contracts are executed.

Adjusted⁽²⁾ IBT margin guidance for BNT162b2 incorporates the current expectation for revenues for the product, less anticipated Adjusted⁽²⁾ costs to manufacture, market and distribute BNT162b2, including applicable royalty expenses and a 50% gross margin split with BioNTech, as well as shared R&D expenses related to BNT162b2 and costs associated with other assets currently in development for the prevention and treatment of COVID-19. It also includes R&D expenses related to other mRNA-based development programs which are excluded from the collaboration with BioNTech. It does not include an allocation of corporate or other overhead costs.

Selected Financial Guidance Ranges Excluding BNT162b2

Pfizer is increasing its previous 2021 financial guidance for revenues and is reaffirming guidance ranges for Adjusted cost of sales⁽²⁾ as a percentage of revenues and Adjusted diluted EPS⁽²⁾ with BNT162b2 contributions excluded.

The midpoint of the revenue guidance range above reflects approximately 6% operational growth compared to 2020 when all revenue impacts related to BNT162b2 are excluded from both periods, which is in line with the company’s stated goal of at least a 6% revenue compound annual growth rate through 2025. The midpoint of Pfizer’s Adjusted diluted EPS⁽²⁾ guidance range excluding BNT162b2 reflects approximately 11% operational growth compared to the prior year.

CAPITAL ALLOCATION

• During the first three months of 2021, Pfizer paid $2.2 billion of cash dividends, or $0.39 per share of common stock.
• In April 2021, Pfizer announced that its board of directors declared a $0.39 second-quarter 2021 dividend. The board decided to maintain Pfizer’s quarterly dividend at its current level despite the planned declaration of a dividend payment by Viatris that would be payable to those Pfizer shareholders that have elected to continue holding Viatris shares received from the combination of Upjohn and Mylan⁽⁴⁾. The decision to maintain the dividend was made based on Pfizer’s strong financial performance and will result in increased dividend income to those shareholders continuing to own shares of both Pfizer and Viatris⁽⁴⁾.
• No share repurchases have been completed to date in 2021. As of May 4, 2021, Pfizer’s remaining share repurchase authorization is $5.3 billion. Current 2021 financial guidance does not reflect any share repurchases in 2021.
• First-quarter 2021 diluted weighted-average shares outstanding used to calculate Reported⁽¹⁾ and Adjusted⁽²⁾ diluted EPS was 5,662 million shares, an increase of 49 million shares compared to the prior-year quarter primarily due to shares issued for employee compensation programs.

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

First-quarter 2021 revenues totaled $14.6 billion, an increase of $4.5 billion, or 45%, compared to the prior-year quarter, reflecting operational growth of $4.2 billion, or 42%, as well as a favorable impact of foreign exchange of $284 million, or 3%.

Compared with the prior-year quarter, first-quarter 2021 revenues were favorably impacted by approximately $400 million as a result of first-quarter 2021 having three additional selling days in the U.S. and four additional selling days in international markets. This increase in selling days will be offset in fourth-quarter 2021, resulting in essentially the same number of selling days in full-year 2021 as full-year 2020.

The favorable impact in first-quarter 2021 from selling days was partially offset by the non-recurrence of favorable impacts related to COVID-19 on first-quarter 2020, including increased demand for certain products of approximately $150 million and additional wholesaler inventories of approximately $100 million. The net favorable impact on first-quarter 2021 revenues of all of the above factors was approximately $150 million, accounting for approximately 1.5 percentage points of operational growth.

First-quarter 2021 operational growth was primarily driven by:

• BNT162b2, which contributed $3.5 billion in global revenues;
• Eliquis globally, up 25% operationally, led by growth in the U.S., emerging markets and developed Europe, driven primarily by continued increased adoption in non-valvular atrial fibrillation and oral anti-coagulant market share gains, as well as a favorable adjustment related to the Medicare “coverage gap” provision resulting from lower than previously expected discounts in prior periods;
• Vyndaqel/Vyndamax globally, up 88% operationally, primarily driven by the approval in February 2020 of the transthyretin amyloid cardiomyopathy (ATTR-CM) indication in the European Union (EU), as well as the continued strong uptake of the ATTR-CM indication in the U.S. and Japan;
• Xeljanz globally, up 18% operationally, primarily driven by:
  • 16% growth in the U.S., primarily reflecting higher volumes within the rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ulcerative colitis (UC) indications, driven by reaching additional patients through improvements in formulary access; and
  • 21% operational growth in international markets, primarily reflecting continued uptake in the RA indication and, to a lesser extent, the UC indication in certain developed markets;
• Xtandi in the U.S., up 28%, primarily driven by continued strong demand in the metastatic and non-metastatic castration-resistant prostate cancer indications, as well as the metastatic castration-sensitive prostate cancer indication, which was approved in the U.S. in December 2019; and
• Inlyta globally, up 34% operationally, primarily reflecting increased demand in the U.S. and developed Europe following the approvals in 2019 for combinations of certain immune checkpoint inhibitors and Inlyta for the first-line treatment of patients with advanced renal cell carcinoma; as well as
• Biosimilars, which grew 79% operationally to $530 million, primarily driven by recent oncology monoclonal antibody biosimilar launches of Ruxience (rituximab), Zirabev (bevacizumab) and Trazimera (trastuzumab) globally, as well as continued growth from Retacrit (epoetin) in the U.S.; and
• Hospital products, which grew 10% operationally to $2.3 billion, primarily driven by Pfizer CentreOne, Pfizer’s contract manufacturing operation, reflecting sales of legacy Upjohn products to Viatris⁽⁴⁾ and remdesivir to Gilead Sciences Inc., as well as growth from recent anti-infective product launches in international markets, partially offset by lower year-over-year volume for certain products globally due to a COVID-19-related surge in demand in the prior-year quarter,

partially offset primarily by lower revenues for:

• Prevnar 13 in the U.S., down 20%, primarily driven by:
  • a 57% decline for the adult indication, driven by disruptions to wellness visits due to COVID-19-related mobility restrictions or limitations, including delaying other vaccinations while receiving COVID-19 inoculations due to CDC guidance, as well as the impact of the revised Advisory Committee on Immunization Practices recommendation for the adult indication to shared clinical decision making and the continued impact of a lower remaining eligible adult population; and
  • a 6% decline for the pediatric indication, primarily reflecting the unfavorable impact of COVID-19 and lower year-over-year birth rates⁽⁸⁾;
• Ibrance in the U.S., down 7%, which reflects relatively stable U.S. prescription volume demand and Ibrance’s continued strong leadership position within the CDK 4/6 class, but also an increase in the proportion of patients accessing Ibrance through Pfizer’s Patient Assistance Program due to economic hardships brought on by the COVID-19 pandemic which is expected to normalize over time as the economic impact of the pandemic subsides; and
• Chantix in the U.S., down 21%, driven by a negative impact from the COVID-19 pandemic resulting in a decline in patient visits to doctors for preventative health purposes, as well as the loss of patent protection in the U.S. in November 2020.

GAAP Reported⁽¹⁾ Income Statement Highlights

SELECTED REPORTED COSTS AND EXPENSES⁽¹⁾

First-quarter 2021 Cost of Sales⁽¹⁾ as a percentage of revenues increased 9.7 percentage points compared with the prior-year quarter. The drivers for the increase include, among other things:

• an increase of approximately 8 percentage points associated with sales of BNT162b2, which includes a charge for the 50% gross margin split with BioNTech; and
• unfavorable changes in product mix, including higher sales of lower margin products from the Pfizer CentreOne operation, partially offset by the favorable impact of higher alliance revenues.

SI&A Expenses⁽¹⁾ increased 8% operationally in first-quarter 2021 compared with the prior-year quarter, reflecting, among other things:

• an increase in deferred compensation savings plan expenses;
• costs related to BNT162b2, primarily driven by a higher provision for healthcare reform fees based on sales; and
• incremental costs associated with the implementation of certain cost reduction and productivity initiatives,

partially offset by:

• lower spending on Chantix following its loss of patent protection in the U.S. in November 2020.

First-quarter 2021 R&D Expenses⁽¹⁾ increased 20% operationally compared with the prior-year quarter, which primarily reflects spending on Pfizer’s efforts to develop BNT162b2 and therapeutics to help treat COVID-19.

Pfizer recorded $1.0 billion of other income––net⁽¹⁾ in first-quarter 2021 compared with $190 million of other deductions––net⁽¹⁾ in first-quarter 2020, primarily driven by net gains on equity securities in first-quarter 2021 versus net losses recorded in first-quarter 2020, higher net periodic benefit credits related to pension and postretirement plans and higher income from collaborations.

Adjusted⁽²⁾ Income Statement Highlights

SELECTED ADJUSTED COSTS AND EXPENSES⁽²⁾

Changes in Adjusted⁽²⁾ costs and expenses in first-quarter 2021 compared to the prior-year quarter were driven primarily by the factors listed in the Reported⁽¹⁾ costs and expenses section above.

A full reconciliation of Reported⁽¹⁾ to Adjusted⁽²⁾ financial measures and associated footnotes can be found in the financial tables section of the press release located at the hyperlink below.

RECENT NOTABLE DEVELOPMENTS (Since February 2, 2021)

Product Developments

    • In February 2021, Pfizer and BioNTech announced results from an in vitro study published in NEJM that demonstrated sera from individuals immunized with BNT162b2 neutralize SARS-CoV-2 with the South African variant spike protein. The study investigated the full set of South African variant (also known as B.1.351 lineage) spike mutations and showed that while the results indicated a reduction in neutralization of virus with all the South African variant spike glycoprotein mutations, all the sera neutralized all the viruses tested.
    • In February 2021, Pfizer and BioNTech announced they have begun a study evaluating the safety and immunogenicity of a third dose of BNT162b2 to understand the effect of a booster on immunity against COVID-19 caused by the circulating and potential newly emerging SARS-CoV-2 variants. The study will include participants from the Phase 1 study in the U.S. who will be offered the opportunity to receive a 30 μg booster of the current vaccine 6 to 12 months after receiving their initial two-dose regimen.
    • In February 2021, Pfizer and BioNTech announced that the first participants have been dosed in a global Phase 2/3 study to further evaluate the safety, tolerability, and immunogenicity of BNT162b2 in preventing COVID-19 in healthy pregnant women 18 years of age and older.
    • In March 2021, Pfizer and BioNTech began a global Phase 1/2/3 continuous study to further evaluate the safety, tolerability, and immunogenicity of BNT162b2 in preventing COVID-19 in healthy children 6 months to 11 years old. Vaccine effectiveness in the study will be inferred through immunobridging to the 16 to 25 year-old population in the pivotal Phase 3 trial. Results from the study are expected to be available in the second half of 2021.
    • In March 2021, Pfizer, the Israel Ministry of Health (MoH) and BioNTech announced real-world evidence demonstrating dramatically lower incidence rates of COVID-19 disease in individuals fully vaccinated with BNT162b2. The analysis from the MoH demonstrated that two weeks after the second vaccine dose protection is even stronger – vaccine effectiveness was at least 97% in preventing symptomatic disease, severe/critical disease and death.
    • In March 2021, Pfizer and BioNTech announced topline results from a pivotal Phase 3 trial in adolescents 12 to 15 years of age with or without prior evidence of SARS-CoV-2 infection.

    • In April 2021, Pfizer and BioNTech announced updated topline results from an analysis of 927 confirmed symptomatic cases of COVID-19 observed in the pivotal Phase 3 study through March 13, 2021, showing BNT162b2 was 91.3% effective against COVID-19, measured seven days through up to six months after the second dose. The vaccine was 100% effective against severe disease as defined by the U.S. Centers for Disease Control and Prevention (CDC), and 95.3% effective against severe COVID-19 as defined by the FDA. Safety data from the Phase 3 study has also been collected from more than 12,000 vaccinated participants who have a follow-up time of at least six months after the second dose, demonstrating a favorable safety and tolerability profile.
  • Regulatory Developments
    • In March 2021, Pfizer and BioNTech announced that the European Medicines Agency (EMA) approved storage of BNT162b2 at -25°C to -15°C for a total of two weeks based on data showing the stability at these temperatures in standard pharmaceutical freezers. This follows approval on February 25, 2021 by the FDA to update the U.S. Emergency Use Authorization (EUA)⁽⁷⁾ Prescribing Information to allow for vaccine vials to be stored at these temperatures for a total of two weeks as an alternative or complement to storage in an ultra-low temperature freezer.
    • In April 2021, Pfizer and BioNTech requested amendments to the U.S. EUA⁽⁷⁾ of BNT162b2 to expand the use in adolescents 12 to 15 years of age. In addition, the companies have since requested similar amendments by other regulatory authorities worldwide.
  • Commercial Developments
    • In February 2021, Pfizer and BioNTech announced an agreement with the European Commission (EC) to supply an additional 200 million doses of BNT162b2 to the 27 EU member states. In April 2021, the EC exercised its option to purchase an additional 100 million doses under the agreement, bringing the total number of doses to be supplied by the companies to the EU in 2021 to 600 million.
    • In February 2021, Pfizer and BioNTech announced that the U.S. government exercised its option for an additional 100 million doses of BNT162b2, bringing the total number of doses to be supplied by the companies to the U.S. government to 300 million. Consistent with the agreements for the prior 200 million doses, the U.S. government will pay $1.95 billion for the additional 100 million doses.
    • In April 2021, Pfizer and BioNTech entered into an agreement with Israel to supply millions of doses in 2022, with an option to purchase millions of additional doses. The companies have also entered into an agreement with Canada to supply up to 125 million doses in 2022 and 2023, with options to purchase up to 60 million additional doses in 2024.
    • As of May 3, 2021, Pfizer, along with its partner BioNTech, has shipped approximately 430 million doses of BNT162b2 to 91 countries and territories around the world.
• Elranatamab (PF-06863135) -- In February 2021, Pfizer announced that the first participant has been dosed in the registration-enabling Phase 2 MagnetisMM-3 study of elranatamab, an investigational B-cell maturation antigen (BCMA) CD3-targeted bispecific antibody, in patients with relapsed/refractory multiple myeloma. New enrollment in the study has been paused while we provide additional information to the FDA regarding three cases of peripheral neuropathy observed in the ongoing Phase 1 MagnetisMM-1 study. Patients who are deriving clinical benefit from elranatamab may continue treatment.
• PF-06482077 (20-Valent Pneumococcal Conjugate Vaccine Candidate)
  • In February 2021, Pfizer announced that the EMA accepted for review the Marketing Authorization Application (MAA) for its 20-valent pneumococcal conjugate vaccine (20vPnC) candidate, as submitted for the prevention of invasive disease and pneumonia caused by Streptococcus pneumoniae serotypes in the vaccine in adults ages 18 years and older. With the MAA acceptance, the formal review process by the EMA’s Committee for Medicinal Products for Human Use (CHMP) begins.
  • In anticipation of the potential for a COVID-19 vaccine booster to be necessary, approved under EUA by the FDA and recommended by the CDC for use in adults as early as the fall or winter of 2021, Pfizer will conduct a study on the safety and immunogenicity of co-administration of its 20vPnC candidate with a booster dose of BNT162b2. Results of the study are expected in the third quarter of 2021 and could potentially inform ACIP recommendations and guidelines surrounding the co-administration of Prevnar-13 or 20vPnC with BNT162b2.
• PF-07321332 (oral antiviral therapeutic for COVID-19) -- In March 2021, Pfizer announced the initiation of a Phase 1 study in healthy adults to evaluate the safety and tolerability of an investigational, novel oral antiviral therapeutic for SARS-CoV-2. The oral antiviral clinical candidate, a SARS-CoV2-3CL protease inhibitor, has demonstrated potent in vitro anti-viral activity against SARS-CoV-2, as well as activity against other coronaviruses. It is the first orally administered coronavirus-specific investigational protease inhibitor to be evaluated in clinical studies.
• Relugolix
  • In March 2021, Myovant Sciences (Myovant) and Pfizer announced positive data from the Phase 3 LIBERTY randomized withdrawal study of relugolix combination therapy (relugolix 40 mg plus estradiol 1.0 mg and norethindrone acetate 0.5 mg) in women with uterine fibroids. The study was designed to assess the safety and efficacy of continued treatment with relugolix combination therapy for up to two years. This follows the announcement in February 2021 of the publication in NEJM of the Phase 3 LIBERTY 1 and LIBERTY 2 studies, which also met their primary endpoints. Relugolix combination tablet is currently under review by the FDA for the treatment of women with uterine fibroids, with a decision expected by the June 1, 2021 target action date.
  • In April 2021, Myovant and Pfizer announced that the first participant has been dosed in the Phase 3 SERENE study evaluating the contraceptive efficacy of relugolix combination tablet (relugolix 40 mg, estradiol 1.0 mg and norethindrone acetate 0.5 mg) in healthy women ages 18-35 who are at risk for pregnancy. The primary efficacy endpoint is the at-risk Pearl Index, defined as the number of on-treatment pregnancies per 100 women-years of treatment. Safety data will also be collected during the study.
• Somatrogon -- In February 2021, Pfizer and OPKO Health Inc. announced that the EMA has validated for review the MAA for somatrogon, a long-acting recombinant human growth hormone intended to be administered once-weekly for the treatment of pediatric patients with growth hormone deficiency.

(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 associated financial schedules and product revenue tables attached to the press release located at the hyperlink referred to above and the attached disclosure notice.

(1) 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.

(2) Adjusted income and its components and Adjusted diluted EPS are defined as reported U.S. GAAP net income⁽¹⁾ and its components and reported diluted EPS⁽¹⁾ excluding purchase accounting adjustments, acquisition-related costs, discontinued operations and certain significant items (some of which may recur, such as actuarial gains and losses from pension and postretirement plan remeasurements, gains on the completion of joint venture transactions, restructuring charges, legal charges or gains and losses from equity securities, but which management does not believe are reflective of ongoing core operations). 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.

As described in 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, management uses Adjusted income, among other factors, to set performance goals and to measure the performance of the overall company. Because Adjusted income is an important internal measurement for Pfizer, management believes that investors’ understanding of our performance is enhanced by disclosing this measure. Pfizer reports Adjusted income, certain components of Adjusted income, and Adjusted diluted EPS in order to present the results of the company’s major operations––the discovery, development, manufacture, marketing and sale of prescription medicines and vaccines––prior to considering certain income statement elements. See the accompanying reconciliations of certain GAAP Reported to Non-GAAP Adjusted information for the first quarter of 2021 and 2020. The 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⁽¹⁾.

(3) 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 2021 reflects the following:

• Does not assume the completion of any business development transactions not completed as of April 4, 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⁽²⁾ on a one-quarter lag.
• Reflects an anticipated negative revenue impact of $0.9 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-April 2021. Financial guidance reflects the anticipated favorable impact of approximately $1.3 billion on revenues and approximately $0.09 on Adjusted diluted EPS⁽²⁾ as a result of changes in foreign exchange rates relative to the U.S. dollar compared to foreign exchange rates from 2020.
• Guidance for Adjusted diluted EPS⁽²⁾ assumes diluted weighted-average shares outstanding of approximately 5.7 billion shares, which currently assumes no share repurchases in 2021.
• Guidance for Adjusted other (income)/deductions⁽²⁾ includes an estimated benefit of approximately $300 million resulting from a change in accounting principle to a more preferable policy under U.S. GAAP to immediately recognize actuarial gains and losses arising from the remeasurement of our pension and postretirement plans. This change went into effect in the first quarter of 2021 and prior period amounts have been recast to conform to the new accounting policy.

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

• 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, which falls in Pfizer’s international first-quarter 2021, 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 for all periods presented.
• 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.

(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 4, 2021 and March 29, 2020 while Pfizer’s first quarter for subsidiaries operating outside the U.S. reflects the three months ended on February 28, 2021 and February 23, 2020.

(6) 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.

(7) BNT162b2 has not been approved or licensed by the U.S. Food and Drug Administration (FDA), but has been authorized for emergency use by the FDA under an Emergency Use Authorization (EUA) to prevent Coronavirus Disease 2019 (COVID-19) for use in individuals 16 years of age and older. The emergency use of this product is 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. Please see the EUA Fact Sheet for Healthcare Providers Administering Vaccine (Vaccination Providers) including full EUA prescribing information available at www.cvdvaccine.com.

(8) The U.S. birth rate decline was 5% compared to 2020 levels, according to Demographic Intelligence.
