Moleculin Biotech, Inc. (NASDAQ: MBRX) entered into agreements to exercise 1,044,329 shares of its February 2025 and August 2025 warrants at exercise prices of $6.63 and $6.3219 per share, respectively. The exercise is expected to generate approximately $6.5 million in gross proceeds before fees, providing the company with additional working capital and general corporate purposes.
The company will also issue new unregistered warrants for up to 2,610,823 shares at an exercise price of $6.63 per share. These warrants will be exercisable only after shareholder approval and will carry a five‑year term, adding a potential dilution layer that investors are closely watching.
Moleculin’s recent 1‑for‑25 reverse stock split, effective December 1, 2025, reduced the number of outstanding shares from roughly 51.7 million to about 2.1 million. While the split lowers the absolute number of shares that could be issued, the underlying dilutive effect remains significant, especially given the company’s limited cash reserves.
The company’s cash position stands at $6.7 million as of September 30, 2025, against a negative free cash flow of $22.45 million over the prior twelve months. The warrant exercise is a critical step to extend the runway, as Moleculin needs an additional $7 million to fund its Phase 3 MIRACLE trial for Annamycin and to support operations into the second quarter of 2026.
The announcement was met with a negative market reaction, driven primarily by concerns over dilution from the new warrants and the company’s ongoing need for capital. Investors view the financing as a sign of continued cash burn and the absence of revenue, despite progress in clinical development.
Analysts note that while the capital raise provides necessary liquidity, it also underscores the company’s high-risk profile and the need for a successful clinical outcome to unlock future value. The event highlights the trade‑off between immediate cash needs and long‑term shareholder dilution in early‑stage biotech companies.
