Moleculin Biotech Inc. (NASDAQ: MBRX) saw its stock fall 34.3% in premarket trading after announcing an agreement with certain warrant holders to immediately exercise outstanding warrants. The deal will bring in roughly $8.3 million in gross proceeds at $3.90 per share while creating new unregistered warrants that could lead to further dilution pending shareholder approval.

Key Points

  • Shares fell 34.3% in premarket trading after Moleculin announced agreements allowing immediate exercise of certain outstanding warrants.
  • Exercised warrants will permit purchase of up to 2,122,652 shares at $3.90 each, generating approximately $8.3 million in gross proceeds.
  • Moleculin will issue up to 6,367,956 new unregistered warrants with an exercise price equal to the lesser of $3.90 or the lowest five-day VWAP; these warrants are exercisable only upon shareholder approval and carry a five-year term.

Overview

Moleculin Biotech Inc. reported an agreement with certain holders of its outstanding warrants that triggered a sharp premarket move in the company's stock - a 34.3% decline on Thursday. Under the terms disclosed by the clinical-stage pharmaceutical company, existing warrants will be exercised immediately, and the company will issue replacement unregistered warrants to the exercising parties.

Terms of the Transaction

The exercised warrants will allow the purchase of up to 2,122,652 shares of Moleculin common stock at an exercise price of $3.90 per share. That immediate exercise is expected to generate approximately $8.3 million in gross proceeds for the company.

In return for the immediate exercises, Moleculin will issue new unregistered warrants to purchase up to 6,367,956 shares of common stock. Those replacement warrants will carry an exercise price equal to the lesser of $3.90 per share or the lowest volume-weighted average price recorded during the next five trading days, a structure the company said could be dilutive to current shareholders.

The new warrants will be exercisable only upon shareholder approval and will have a five-year term.

Use of Proceeds, Timing and Conditions

Moleculin indicated it intends to use the net proceeds for working capital and other general corporate purposes. The transaction is expected to close on or about February 20, 2026, subject to customary closing conditions. Roth Capital Partners is named as the financial advisor to Moleculin for this transaction.

The company has also agreed to file a registration statement with the U.S. Securities and Exchange Commission covering the resale of shares that may be issued upon exercise of the new warrants.

Clinical Programs

Moleculin is advancing a Phase 3 clinical trial called MIRACLE, which evaluates its lead program, Annamycin, in combination with cytarabine for patients with relapsed or refractory acute myeloid leukemia (AML). The company is additionally developing other therapeutic candidates aimed at hard-to-treat tumors and viruses.


Key takeaways

  • Stock reaction: Shares fell 34.3% in premarket trading following the announcement.
  • Financing mechanics: Immediate exercise of warrants to buy up to 2,122,652 shares at $3.90, generating about $8.3 million in gross proceeds.
  • Replacement warrants: Up to 6,367,956 new unregistered warrants to be issued, with an exercise price tied to the lower of $3.90 or the lowest five-day VWAP; these will be exercisable only after shareholder approval and will have a five-year term.

Risks and uncertainties

  • Potential dilution - The issuance of replacement warrants could increase the number of shares outstanding if exercised, which may dilute existing shareholders.
  • Closing conditions - The transaction is subject to customary closing conditions and a target close date around February 20, 2026; timing and completion are not guaranteed.
  • Shareholder approval - The new warrants will not be exercisable until shareholder approval is obtained, introducing an element of uncertainty about the timing and ultimate effect of the warrants.

Context for investors

The company framed the financing as a source of working capital and general corporate funding while continuing development of its lead oncology program and other candidates. Moleculin's Phase 3 MIRACLE trial and other development efforts remain in progress.

Roth Capital Partners serves as financial advisor, and the company will file the necessary registration statement with the SEC for resale of shares underlying the new warrants.

Investors should note the explicit transaction mechanics and timing described by the company when assessing ownership dilution and near-term capital structure changes.

Risks

  • Potential dilution to existing shareholders from the issuance and possible exercise of up to 6,367,956 new warrants - impacts equity holders and the broader equities market segment.
  • Transaction completion is subject to customary closing conditions with an expected close around February 20, 2026 - introduces timing and execution risk for corporate financing markets.
  • The new warrants require shareholder approval before they become exercisable, creating uncertainty about when or if the new warrants will be converted into common shares - relevant to investors in Moleculin equity and warrant instruments.
