Pfizer Shares Hit Annual Peak on Regulatory and Strategic Momentum

Pfizer Inc. (PFE) stock has climbed to a new 52-week high, trading around $27.70 in recent sessions. This upward movement is supported by a confluence of favorable regulatory updates, a fresh cost-saving initiative, and a solid financial foundation laid out by the company earlier this year.

The current share price strength builds upon the robust full-year 2025 results and 2026 guidance confirmed in early February. For the fourth quarter of 2025, the pharmaceutical giant reported revenue of $17.6 billion, contributing to an annual total of $62.6 billion. Looking ahead, CEO Albert Bourla has reaffirmed the company's outlook for 2026, projecting revenues in the range of $59.5 billion to $62.5 billion. Adjusted earnings per share are anticipated to be between $2.80 and $3.00.

Bourla has highlighted the critical role of Pfizer's development pipeline, with a specific focus on oncology and obesity treatments. The market appears to be increasingly valuing the potential of these research projects as the company moves beyond the revenue peak generated by its COVID-19 products.

Key Regulatory Catalyst for Hympavzi

A significant driver behind the equity's performance is a recent regulatory development. The U.S. Food and Drug Administration (FDA) has granted a Priority Review designation for Pfizer's supplemental Biologics License Application (sBLA) for Hympavzi (marstacimab). The agency has set a target action date for the second quarter of 2026.

Should investors sell immediately? Or is it worth buying Pfizer?

This application seeks to expand the drug's label to include children aged 6 to 11 with hemophilia A or B without inhibitors, as well as patients aged 6 and above who have inhibitors. A successful approval would position Hympavzi as the first prophylactic non-factor therapy for this specific pediatric patient group, significantly bolstering Pfizer's standing in the rare disease segment.

Strategic Pricing Initiative "TrumpRx"

In parallel, Pfizer has launched a new pricing model under its "TrumpRx" initiative. This program offers substantial discounts on more than 30 branded prescription medicines, including treatments for conditions such as migraine and rheumatoid arthritis. Forming part of a broader "Most Favored Nation" agreement, the strategy aims to enhance affordability for U.S. patients without compromising the company's market access.

Summary of Primary Growth Drivers

• FDA Priority Review: Accelerated regulatory pathway for Hympavzi expansion, with a Q2 2026 decision date.
• Cost Reduction Program: "TrumpRx" initiative providing discounts on a portfolio of key medicines.
• Revenue Forecast: 2026 guidance maintained at $59.5 to $62.5 billion.
