Insights

Financial Analyst

Major capital raise strengthens balance sheet, extending runway by approximately 18 months with minimal dilution relative to potential value creation.

The $75M offering demonstrates strong institutional support and efficient capital markets execution. The pricing at $12.00 per share and inclusion of pre-funded warrants suggests strategic consideration for both traditional and specialized biotech investors. The extended cash runway into 2027 provides significant operational flexibility and reduced financing risk. The underwriting syndicate includes top-tier healthcare investment banks, indicating high-quality institutional distribution.

The warrant structure with ownership caps (4.99% to 19.99%) shows thoughtful consideration of ownership dilution while maintaining flexibility for larger investors. The estimated $70M in net proceeds provides substantial operational capital with reasonable banking fees of approximately 6.7%.

Capital Markets Specialist

Well-structured offering balances immediate capital needs with strategic flexibility through innovative warrant mechanism and strong syndicate support.

The deal structure reveals sophisticated capital markets strategy, combining traditional equity with pre-funded warrants to optimize investor participation. The 30-day underwriter option for additional shares (937,508) provides flexibility for excess demand. The warrant exercise provisions, including cashless exercise options and beneficial ownership limitations, demonstrate careful consideration of market dynamics and regulatory requirements. The S-3 shelf registration utilization indicates efficient securities law compliance and market readiness.

Item 1.01. Entry into a Material Definitive Agreement.

On June 24, 2025, Forte Biosciences, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with TD Securities (USA) LLC, Evercore Group L.L.C., Guggenheim Securities, LLC, and Chardan Capital Markets, LLC, as representatives (the “Representatives”) of the several underwriters named therein (collectively, the “Underwriters”), relating to the issuance and sale in a public offering (the “Offering”) of 5,630,450 shares of the Company’s common stock, par value $0.001 per share, at a price to the public of $12.00 per share (the “Shares”), and, in lieu of Shares to certain investors, pre-funded warrants to purchase 619,606 Shares (the “Pre-Funded Warrants”) at a price to the public of $11.999 per Pre-Funded Warrant, which represents the per share public offering price for the Shares less the $0.001 exercise price for each such Pre-Funded Warrant. The Company also granted the Underwriters an option, exercisable for a period of 30 days, to purchase up to an additional 937,508 Shares (the “Option”). All of the Shares and Pre-Funded Warrants in the Offering are being sold by the Company.

The gross proceeds from the Offering are expected to be approximately $75.0 million before deducting underwriting discounts and commissions and other offering expenses, and assuming no exercise of the Option by the Underwriters. The Offering is expected to close on or about June 26, 2025, subject to satisfaction of customary closing conditions.

We estimate the net proceeds to us from this offering will be approximately $70.0 million (or approximately $80.5 million if the underwriters’ option to purchase additional shares is exercised in full) after deducting underwriting discounts and commissions and estimated offering expenses payable by us. Based on our planned use of the net proceeds from this offering and our existing cash and cash equivalents, we estimate that such funds will be sufficient to enable us to fund our operating expenses and capital expenditure requirements into 2027.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement and may be subject to limitations agreed upon by such parties.

The Offering is being made pursuant to the Company’s effective registration statement on Form S-3 (File No. 333-286226) (the “Registration Statement”), previously filed with and declared effective by the Securities and Exchange Commission (the “SEC”). A preliminary prospectus supplement and accompanying prospectus relating to and describing the terms of the Offering has been filed with the SEC and a final prospectus supplement and accompanying prospectus relating to the offering will also be filed with the SEC.

Each Pre-Funded Warrant will have an exercise price of $0.001 per share. The exercise price of the Pre-Funded Warrants and the number of shares of common stock issuable upon exercise of each Pre-Funded Warrant are subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the common stock. The Pre-Funded Warrants are exercisable, at the option of each holder, in whole or in part, through a cash purchase or a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the Pre-Funded Warrant. Under the Pre-Funded Warrants, the Company may not effect the exercise of any Pre-Funded Warrants, and a holder will not be entitled to exercise any portion of any Pre-Funded Warrant that, upon giving effect to such exercise, would cause the aggregate number of shares of common stock beneficially owned by the holder (together with its affiliates) to exceed 4.99% or, at the election of the holder prior to the issuance of such warrant, a different percentage not in excess of 9.99% of the number of shares of common stock that would be issued and outstanding immediately after such exercise. However, any holder of a Pre-Funded Warrant may increase or decrease such percentage to any other percentage not in excess of 19.99% upon at least 61 days’ prior notice from the holder to the Company. In the event of a fundamental transaction, as described in the Pre-Funded Warrants, the holders of the Pre-Funded Warrants will be entitled to receive upon exercise of the Pre-Funded Warrants the same amount and kind of securities, cash or property that the holders would have received had they exercised the Pre-Funded Warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the Pre-Funded Warrants.

The foregoing descriptions of the terms of the Underwriting Agreement and the Pre-Funded Warrants do not purport to be complete and are each qualified in their entirety by reference to the Underwriting Agreement and the form of Pre-Funded Warrant, respectively, which are filed as Exhibit 1.1 and Exhibit 4.1 hereto and are incorporated herein by reference.

A copy of the opinion of Wilson Sonsini Goodrich & Rosati, P.C. relating to the validity of the Shares, the Pre-Funded Warrants and the shares underlying the Pre-Funded Warrants is filed as Exhibit 5.1 hereto and is incorporated by reference into the Registration Statement.

Item 8.01. Other Events.

A copy of the press release announcing the pricing of the Offering is attached to this Current Report on Form 8-K as Exhibit 99.1 and incorporated herein by reference.
