Number of Hedge Fund Holders: 137

Eli Lilly and Company (NYSE:LLY) is one of the best stocks to buy for the next 15 years. On May 7, Eli Lilly executed its largest bond issuance to date, selling $9 billion in investment-grade debt to fund a recent surge in acquisitions. The offering, which initially targeted $8 billion, saw high investor demand following a credit rating upgrade by S&P Global Ratings and a favorable market environment.

The sale consisted of eight tranches with maturities spanning 2 to 40 years, with the longest-term bonds yielding 0.8 percentage points above Treasuries. The proceeds are earmarked for general corporate purposes and the financing of two major deals totaling nearly $15 billion: the $7.8 billion acquisition of sleep-drug producer Centessa Pharmaceuticals Plc and the $7 billion purchase of cancer-drug developer Kelonia Therapeutics.

Notably, the terms include a provision where Eli Lilly and Company (NYSE:LLY) must repurchase certain notes at 101 cents on the dollar if the Centessa transaction fails to close. This capital raise follows a strong first-quarter performance and increased 2026 guidance driven by high demand for the company’s weight-loss medications.

Eli Lilly and Company (NYSE:LLY) is a healthcare company that develops human pharmaceutical products, including cardiometabolic health, oncology, and immunology products.
