    Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

    At the 2025 annual meeting of stockholders (the “Annual Meeting”) of Tango Therapeutics, Inc. (the “Company”), held on June 5, 2025, the stockholders of the Company approved an amendment to Company’s Second Amended and Restated Certificate of Incorporation, as amended to date, to increase the number of authorized shares of common stock from 200,000,000 to 400,000,000. The certificate of amendment of the Company’s Second Amended and Restated Certificate of Incorporation (the “Certificate of Amendment”), was filed with the Secretary of State of the State of Delaware on June 5, 2025 and became effective upon filing.

    The foregoing description is qualified in its entirety by the Certificate of Amendment, which is attached as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.

    The Annual Meeting of the Company was held in a virtual-only format on June 5, 2025 at 9:00 a.m., Eastern Time via live webcast.

As of April 8, 2025, the record date for the Annual Meeting, the number of shares of the Company’s common stock, $0.001 par value per share (“Common Stock”), outstanding and entitled to vote at the Annual Meeting was 108,107,890. The number of shares of Common Stock present or represented by valid proxy at the Annual Meeting was 96,845,552, representing 89.58% of the total number of shares of Common Stock entitled to vote at the Annual Meeting, thus establishing a quorum for the Annual Meeting. Shares present virtually during the Annual Meeting were considered shares of Common Stock represented in person at the Annual Meeting. Each share of Common Stock was entitled to one vote with respect to matters submitted to the Company’s stockholders at the Annual Meeting.

    At the Annual Meeting, the Company’s stockholders were asked to vote on the following matters, which are described in detail in the Proxy Statement: (i) to elect one Class I director nominee to the Company’s Board of Directors (the “Board”), to hold office until the 2028 annual meeting of stockholders and her successor is duly elected and qualified, or until her earlier resignation or removal (“Proposal 1”), (ii) to ratify the selection of PricewaterhouseCoopers, LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025 (“Proposal 2”); (iii) to approve an amendment to the Company’s Second Amended and Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 200,000,000 to 400,000,000 (“Proposal 3”); (iv) to approve, on a non-binding, advisory basis, of the compensation of the Company’s named executive officers (“Proposal 4”); (v) to vote, on a non-binding, advisory basis, on the frequency of future non-binding, advisory votes on the compensation of the Company’s named executive officers (“Proposal 5”).
