When news broke that Johnson & Johnson was in talks to acquire Protagonist Therapeutics (NASDAQ:PTGX), the stock surged before trading was halted for volatility. Whether or not the deal closes, the signal to investors was unmistakable: peptides are back. Long viewed as hard to develop, lacking bioavailability when taken orally and more complex than biologics, they’ve proven their commercial power through GLP-1 blockbusters like Wegovy, Rybelsus and Zepbound - medicines that are now addressing a billion patients with major chronic metabolic conditions, and now dominate the multi billion dollar diabetes and weight-loss markets.

Johnson & Johnson’s rumored Protagonist buyout demonstrates its proven M&A strategy: divesting low-growth units to fund high-margin, innovative assets.
Johnson & Johnson beats Q3 estimates, raises 2025 sales guidance, and announces plans to spin off its $9.2 billion orthopedics business, DePuy Synthes.
