Item 8.01

Other Events.

As previously disclosed, on November 21, 2025, Tango Therapeutics, Inc. (the “Company”) entered into a Sales Agreement (the “Sales Agreement”) with Leerink Partners LLC (the “Sales Agent”), with respect to an at-the-market offering program pursuant to which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, par value $0.001 per share (the “Common Stock”), through the Sales Agent. The Company previously filed a registration statement on Form S-3ASR (File No. 333-291684) (the “Registration Statement”) with the Securities and Exchange Commission on November 21, 2025, which included a sales agreement prospectus supplement relating to the offer and sale of shares of Common Stock having an aggregate offering price of up to $100,000,000 (the “Shares”) pursuant to the Sales Agreement (the “Prior Prospectus Supplement”). As of the date hereof, the Company has sold an aggregate amount of approximately $64,389,566 of Shares under the Prior Prospectus Supplement, and an aggregate amount of approximately $35,610,434 of Shares remain unsold under the Prior Prospectus Supplement.

On August 11, 2026, the Company filed an additional prospectus supplement relating to the offer and sale of shares of Common Stock having an aggregate offering price of up to $400,000,000 (the “New Prospectus Supplement Shares”) pursuant to the Sales Agreement, which includes approximately $35,610,434 of unsold Shares under the Prior Prospectus Supplement. Accordingly, the offering pursuant to the Prior Prospectus Supplement has been terminated, and the Company will not make any further offer or sale of Shares pursuant to the Prior Prospectus Supplement. The New Prospectus Supplement Shares to be offered and sold under the Sales Agreement, if any, will be offered and sold pursuant to the Registration Statement, which became automatically effective upon filing. Goodwin Procter LLP, counsel to the Company, has issued a legal opinion relating to the New Prospectus Supplement Shares. A copy of such legal opinion, including the consent included therein, is attached as Exhibit 5.1 hereto.

This Current Report on Form 8-K shall not constitute an offer to sell or solicitation of an offer to buy any New Prospectus Supplement Shares, nor shall there be any offer, solicitation or sale of the New Prospectus Supplement Shares in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities law of such state or jurisdiction.
