Moleculin Biotech Announces 1-for-25 Reverse Stock Split, Reducing Outstanding Shares to 2.1 Million
- Reverse Stock Split Implementation: Moleculin Biotech announced a 1-for-25 reverse stock split effective December 1, 2025, reducing outstanding shares from approximately 51.7 million to about 2.1 million, aimed at increasing share price to meet Nasdaq listing requirements.
- Trading Impact: Post-split, Moleculin's common stock will open on the Nasdaq Capital Market under the new CUSIP number 60855D 408, and while facing challenges from reduced share circulation, the company hopes to enhance its market image through this action.
- Shareholder Rights Adjustment: The reverse stock split will not issue any fractional shares, and shareholders entitled to fractional shares will receive cash compensation, a measure intended to protect shareholder rights and simplify the shareholder structure.
- Increased Financing Needs: Moleculin anticipates requiring significant additional financing to support its clinical trials; while the reverse split may help boost share price, the company still faces uncertainties in securing funding to advance its drug development plans.
