Better Buy in 2026: Pfizer or Merck?

Core Viewpoint - The pharmaceutical giants Pfizer and Merck have underperformed in 2023, facing financial challenges and upcoming patent cliffs, leading to uncertainty in their medium-term outlooks. The article compares both companies to determine which presents a better investment opportunity heading into the new year. Pfizer - Pfizer's Eliquis, a leading blood thinner, is approaching patent expiration, which could exacerbate its already slow revenue and earnings growth [3] - The company has expanded its pipeline through internal efforts, acquisitions, and licensing deals, launching new products that are expected to impact financial results positively in the future [4] - Notable pipeline candidates include MET-097i, a promising weight loss drug with fewer side effects and a long-acting dosing schedule, and PF-4404, a cancer therapy that could become a standard treatment for certain cancers [5][7] - Pfizer is also implementing cost-cutting measures and has secured a deal with the White House to be exempt from tariffs for three years, which may help improve its margins and bottom line [8] Merck - Merck's sales from its HPV vaccines, Gardasil and Gardasil 9, have declined due to lower sales in China, and its best-selling cancer drug Keytruda faces a patent cliff by 2028 [9] - The company has introduced a new subcutaneous version of Keytruda, which offers a more convenient administration method and is expected to mitigate sales losses from biosimilars [10] - Merck's pipeline includes successful products like Winrevair for pulmonary arterial hypertension and Capvaxive, a pneumonia vaccine, both of which are expected to generate significant revenue [12][13] - An acquisition that adds CD388 to its pipeline could potentially transform the influenza vaccine market, indicating strong future prospects for Merck [13] Investment Comparison - Both Pfizer and Merck are considered viable long-term investment options, but Merck is viewed as the stronger choice due to better financial results and a more developed plan to address challenges [14][16] - Merck's higher profit margins and faster dividend growth over the past decade make it more attractive for dividend-seeking investors, despite Pfizer's higher forward dividend yield [17]
