Meta Platforms, Inc. (META) vs Merck & Co., Inc. (MRK)

Meta Platforms, Inc. is the world’s largest social media company, reaching nearly 4 billion monthly active users globally. Its core business, known as the Family of Apps, includes Facebook, Instagram, Messenger, and WhatsApp. Users rely on these platforms for a wide range of activities, from staying connected with friends and following public figures to operating digital businesses at no cost. Meta monetizes its ecosystem by using customer data generated across its apps to sell advertising to digital marketers. Although the company has invested significantly in Reality Labs, that segment still represents only a small portion of Meta’s total revenue.

Merck & Co., Inc. develops pharmaceutical products across multiple therapeutic areas, including cardiometabolic disorders, oncology, and infectious diseases. In cancer treatment, its immuno-oncology portfolio, led by Keytruda, represents a significant driver of total revenue. The company also maintains a strong vaccines business focused on preventing pediatric illnesses, alongside Gardasil for human papillomavirus. In addition, Merck markets animal health products. Geographically, 47% of the company’s sales come from its U.S. human health segment, which includes pharmaceuticals and vaccines.
