Boston-based cancer drug developer Aktis Oncology has upsized its U.S. initial public offering (IPO), aiming to raise $317.7 million by offering approximately 17.7 million shares to the public.
The move signals strong investor interest in the biotech sector at the beginning of 2026 and follows the company’s strategic partnerships and research progress.
If successful, the IPO could value the company at up to about $945 million and lay the foundation for advancing its tumor-targeting treatments through later-stage clinical trials.
Why This Is Happening
Aktis Oncology operates in a niche of targeted radiopharmaceuticals, a growing area of cancer treatment that seeks to deliver potent radiation directly to tumor cells while sparing normal tissues.
The company’s decision to upsize the IPO, increasing the number of shares offered from its prior filing, reflects growing demand from institutional investors and confidence fueled in part by a significant investment commitment from pharmaceutical giant Eli Lilly.
Eli Lilly has indicated interest in purchasing about $100 million worth of shares at the IPO price, building on its earlier collaboration and equity investment with Aktis.
What the IPO Entails
Aktis plans to offer around 17.7 million shares priced between $16 and $18 each, which, at the top of that range, could generate roughly $317.7 million in gross proceeds for the company.
Underwriters on the deal include J.P. Morgan, BofA Securities, Leerink Partners, and TD Cowen.
The company will list its common stock on the Nasdaq Global Market under the ticker symbol “AKTS.”
