A Letter from Our Chairman & CEO

• We secured eight key regulatory approvals, completed 13 regulatory submissions and initiated 10 pivotal study starts, as we continue to advance our robust R&D pipeline of potential breakthrough medicines and vaccines.
• We maintained our industry-leading clinical success rates ¹ and further improved our cycle times, which already were among the industry’s best,² and we did all of this while maintaining our high standards of quality, safety and scientific rigor.
• We completed four acquisitions – Arena Pharmaceuticals, Biohaven Pharmaceuticals, Global Blood Therapeutics, and ReViral – which have further strengthened both our pipeline and our current portfolio of innovative offerings for patients.
• We were named to 10 different “best employer” lists, including those published by Forbes, LinkedIn, Glassdoor, and others.
• We exceeded $100 billion in revenues for the first time in our 174-year history.
• And, most important, more than 1.3 billion patients around the world were treated with our medicines and vaccines.³ A truly humbling achievement.

Maintaining Our COVID-19 Leadership

During the year, we also continued to lead the battle against COVID-19. As the virus continued to evolve, Pfizer scientists were up to the challenge – using our flexible mRNA platform to swiftly create a new vaccine candidate based on the emerging Omicron BA.4 and BA.5 subvariants. By September, our BA.4/BA.5-adapted bivalent vaccine had been authorized by both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) as a booster dose for ages 12 years and older. By November, both agencies had authorized it for 5 years of age and older. Then in December, the Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine received FDA authorization as the third 3-µg dose in the three-dose primary series for children 6 months through 4 years of age.

We are proud to have maintained our leadership position throughout the public health booster campaign. As of February 22, 2023, we held a 64% market share of bivalent boosters in the U.S. ⁴ – which is a significant expansion on the booster share leadership position that we already held before the bivalent booster launch – and our bivalent booster market shares are even higher in several key markets outside the U.S. We believe our best-in-class mRNA capability, coupled with our proven and reliable manufacturing network, will ensure we are well positioned to continue to adapt our vaccine as needed and get it to people around the world.

Our COVID-19 oral treatment, PAXLOVID ^® (nirmatrelvir tablets and ritonavir tablets), has shown to be an important complementary tool to vaccination strategies for the estimated 40% of the global population at high risk for progressing to severe disease.⁵ PAXLOVID has demonstrated robust efficacy, a consistent safety profile, and potential to help mitigate the burden of COVID-19 on patients and their families, health systems and society.⁶ As of March 1, 2023, we have shipped 44 million treatment courses to 63 countries around the world.

Leading the Charge for Equitable Access

During the year, we also took bold action to help ensure our breakthroughs get into the hands of those who need them.

We’re living in a time when science is increasingly demonstrating the ability to take on the world’s most devastating diseases. Unfortunately, there’s a huge health equity gap in our world that determines which of us can access these innovations – and which of us can’t. At Pfizer, we are committed to helping close this gap as quickly as possible. That’s why we launched An Accord for a Healthier World. Through this groundbreaking initiative, Pfizer now offers on a not-for-profit basis the full portfolio of medicines and vaccines for which we have global rights to 45 lower-income countries – with the hope of giving the 1.2 billion people living in these countries access to hundreds of lifesaving and life-changing products that they couldn’t access before.

But as we learned in the COVID-19 vaccine rollout, ensuring supply is only the first step to helping patients. For this reason, another key element of the Accord is collaborating with global health leaders to make improvements in diagnosis, education, infrastructure, innovative financing, and more. I'm proud to say that the first shipments of our products arrived in Rwanda in September 2022, and we are working with them and other governments – including in Ghana, Malawi, and Senegal – on future deliveries, as well as health system improvements to help make sure our products reach those in need.

Here in the U.S., I’m equally proud of the important work being done by Pfizer’s Multicultural Health Equity Collective, which recently convened more than 100 health equity luminaries from across the U.S. to engage in candid conversations about the drivers and impact of systemic racism on healthcare. The dialogue highlighted creative solutions that are already starting to reduce health disparities in local communities across the country.

A Bright Future for Pfizer and for Patients

Looking ahead, Pfizer’s future appears to be even brighter than our present. We’re in the midst of an 18-month period during which we expect to have up to an unprecedented 19 new products or indications in the market. Fifteen of these 19 are from our internal pipeline with the remaining four coming to Pfizer via recent business development deals. These potential medicines and vaccines cut across a range of therapeutic areas and include candidates for multiple myeloma, prostate cancer, respiratory syncytial virus (RSV), flu, pneumococcal disease, migraine, ulcerative colitis, and sickle cell disease – among others. This represents a tremendous opportunity to improve health outcomes for patients around the world. This is the promise of our science at work.

And, of course, we have many more potential vaccines and medicines in our pipeline, with numerous launches expected in the 2024-2030 timeframe, if successful in clinical trials and approved. Some of the most promising assets include our oral GLP-1 candidate for diabetes and obesity, potential combination vaccines for flu, COVID-19, and RSV, our potential vaccines for Lyme disease and shingles, multiple new oncology product candidates, including ARV-471 and our CDK4 inhibitor for endocrine receptor-positive breast cancer, our gene therapy candidates for hemophilia A, hemophilia B, and Duchenne muscular dystrophy, and many more.

In addition, given the strength of our balance sheet and cash flows, we will continue to leverage business development opportunities to advance our business strategies and objectives. Our business development efforts remain focused on compelling external science in the form of both later-stage assets, as well as earlier medical innovations, that have the potential to be breakthroughs for patients. We will be looking primarily at therapeutic areas and platforms where we believe we have the scientific skills and acumen to add substantial value and select the most successful targets.

In summary, 2022 was an outstanding year for our company, with our key growth drivers providing evidence of the depth and breadth of our portfolio. With the unprecedented wave of innovations expected to emerge from our scientific pipeline in the near term, potential business development activities, our increased investments in our R&D and commercial capabilities, and additional potential new products and indications coming in the second half of the decade, we believe we can build on the momentum we have created to deliver life-changing innovations to even more patients around the world.
