Windtree Therapeutics Announces $520M BNB Token Investment Plan

Windtree Therapeutics announced that it secured funding agreements worth up to $520 million to buy BNB tokens for its treasury. The biotech company plans to use 99% of the proceeds to purchase the cryptocurrency.

The funding comes from two sources. Windtree established a $500 million equity line of credit that requires stockholder approval to increase authorized common shares. The company also entered into a $20 million stock purchase agreement with Build and Build Corp.

The equity line allows Windtree to draw funds as needed, up to the $500 million limit. Combined with the stock sale, the total available capital reaches $520 million. Once shareholders approve the share increase, Windtree will deploy nearly all funds to acquire BNB tokens.

“We are excited to incorporate these new facilities to enable our future BNB acquisitions as part of our BNB treasury strategy. Pending stockholder approval, the opportunity to secure additional funds for purchasing more BNB cryptocurrency is essential to our strategy.”

said CEO Jed Latkin.

Patrick Horsman, CFA and Director of Build and Build Corp, said Windtree’s approach reflects “forward-thinking” value creation. He noted the equity line provides the flexibility and scale needed for the digital asset treasury plan.

The announcement follows recent crypto initiatives by Windtree. On July 16, Build and Build Corp led a $60 million investment in the company, with up to $140 million in follow-on commitments available. On July 22, Windtree partnered with Kraken for custody, trading, and over-the-counter services for its BNB holdings.

Windtree operates as a biotechnology firm based in Warrington, Pennsylvania, with two therapeutic development programs. The company began building its crypto treasury division in July 2025 to diversify its balance sheet using blockchain-based currencies.

The biotech company has rapidly expanded its cryptocurrency focus while maintaining its core pharmaceutical business. The new funding agreements represent the largest capital raise for Windtree’s BNB strategy to date.
