Tenaya Therapeutics (NASDAQ: TNYA) plans $60M stock and warrant sale

Rhea-AI Filing Summary

Tenaya Therapeutics is raising capital by offering 50,000,000 units in an underwritten public stock and warrant sale. Each unit is priced at $1.20 and includes one share of common stock and one five-year warrant to buy a share at $1.50, with underwriters purchasing at $1.128 per unit. The transaction is expected to generate approximately $60 million in gross proceeds and is scheduled to close on December 15, 2025, subject to customary conditions.

The warrants can be exercised for cash, or on a cashless basis if no effective registration statement covers the underlying shares, and adjust for stock splits and similar events. Exercises are limited so that, after giving effect to an exercise, a holder (together with its affiliates) cannot exceed 4.99% or, if elected, 9.99% of Tenaya’s outstanding common stock or combined voting power, with the percentage adjustable, upon at least 61 days’ notice, to a level not above 19.99%. The company, its officers and directors, and certain shareholders have agreed to a 60-day lock-up, and the deal is being conducted under an already effective shelf registration statement.

Insights

Equity capital markets analyst

Tenaya raises about $60M through a large unit offering of stock plus five-year warrants.

Tenaya Therapeutics is issuing 50,000,000 units at $1.20 each in a firm-commitment underwritten transaction, with underwriters paying $1.128 per unit. Each unit combines one share of common stock with a warrant exercisable at $1.50 per share for five years, and the deal is expected to generate approximately $60 million in gross proceeds, subject to closing on December 15, 2025.

Because all units are sold by the company, this is a primary equity financing that brings in cash immediately while also granting investors longer-dated warrants. The warrants include adjustment features for stock dividends, stock splits, combinations, reclassifications and similar events, helping keep the economic terms comparable if the share structure changes over time. Warrants may be exercised for cash, or on a cashless basis if no effective registration statement covers the underlying shares at the time of exercise.

Ownership caps of 4.99% or, at the holder’s election, 9.99% of outstanding common stock or combined voting power apply after giving effect to any exercise, and the holder can adjust this percentage up or down, not above 19.99%, with at least 61 days’ notice. A 60-day lock-up binds the company, its officers and directors, and certain other holders, limiting additional share sales shortly after the offering. Together, these terms shape how and when additional shares from warrant exercises can enter the market over time.

Item 1.01 Entry into a Material Definitive Agreement.

On December 11, 2025, Tenaya Therapeutics, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Leerink Partners LLC and Piper Sandler & Co., as representatives (the “Representatives”) of the underwriters listed therein (the “Underwriters”), relating to the issuance and sale in a firm commitment underwritten public offering (the “Offering”) of 50,000,000 units (the “Units”), at a public offering price of $1.20 per Unit, consisting of one share of the Company’s common stock, par value $0.0001 per share (the “Common Stock”, and such shares, the “Shares”) and one warrant to purchase one share of Common Stock at an exercise price of $1.50 per share that is exercisable for a period of five years from the date of issuance (a “Warrant”). Under the terms of the Underwriting Agreement, the Underwriters have agreed to purchase the Units from the Company at a price of $1.128 per share. All of the Units in the Offering are being sold by the Company. The Shares and the Warrants comprising the Units will be immediately separable upon issuance and will be issued separately in the Offering.

Gross proceeds from the Offering before deducting underwriting discounts and commissions and other offering expenses payable by the Company are expected to be approximately $60 million. The Offering is expected to close on December 15, 2025, subject to the satisfaction of customary closing conditions.

The Offering was made pursuant to the Company’s registration statement on Form S-3 (File No. 333-286005) (the “Registration Statement”), which was filed with the Securities and Exchange Commission (the “SEC”) on March 21, 2025 and declared effective by the SEC on March 31, 2025.

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. in addition, subject to certain exceptions, the Company, its officers and directors and certain other holders of the Common Stock have agreed not to offer, sell, transfer, or otherwise dispose of any shares of Common Stock during the 60-day period following the date of the Underwriting Agreement, without first obtaining the written consent of the Representatives.

The exercise price and the number of shares of Common Stock issuable upon exercise of the Warrants 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 Warrants will be exercisable on or after the date of issuance until five years from the date of issuance. The Warrants will be exercisable, in the holder’s discretion, by (i) payment in full in immediately available funds for the number of shares of Common Stock purchased upon such exercise or (ii) in the event that there is no effective registration statement registering the shares of Common Stock underlying the Warrants at the time of such exercise, 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 applicable Warrant. Under the Warrants, the Company may not effect the exercise of any Warrant, and a holder will not be entitled to exercise any portion of any Warrant that, upon giving effect to such exercise, would cause (a) the aggregate number of shares of Common Stock beneficially owned by such holder (together with its affiliates) to exceed 4.99% or, at the election of the holder prior to the issuance of the Warrant, 9.99% of the total number of shares of Common Stock outstanding immediately after giving effect to the exercise or (b) the combined voting power of the Company’s securities beneficially owned by such holder (together with its affiliates) to exceed 4.99% or, at the election of the holder prior to the issuance of the Warrant, 9.99% of the combined voting power of all of the Company’s securities immediately outstanding after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Warrant, which percentage may be changed at the holder’s election to a higher or lower percentage not in excess of 19.99% (or, at the election of the holder prior to the issuance of such warrant, 9.99%) upon at least 61 days’ notice to the Company.

In the event of certain fundamental transactions, a holder of Warrants will be entitled to receive, upon exercise of the Warrants, the kind and amount of securities, cash or other property that such holder would have received had they exercised the Warrants immediately prior to the fundamental transaction without regard to any limitations on exercise contained in the Warrants.

The foregoing descriptions of the terms of the Underwriting Agreement and the Warrants do not purport to be complete and are each qualified in their entirety by reference to the Underwriting Agreement and the Form of 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 Warrants, and the shares underlying the Warrants is filed as Exhibit 5.1 hereto and is incorporated by reference into the Registration Statement.
