Item 5.07 Submission of Matters to a Vote of Security Holders.
On December 19, 2025, Adicet Bio, Inc., a Delaware corporation (the “Company”) held its 2025 Special Meeting of Stockholders (the “Special Meeting”). At the Special Meeting, the Company’s stockholders considered and voted on the two proposals set forth below, each of which is described in greater detail in the Company’s definitive proxy statement on Schedule 14A, which was filed with the U.S. Securities and Exchange Commission on November 17, 2025. The final voting results are set forth below.
Proposal 1 – Approval of Reverse Stock Split
The stockholders of the Company approved the amendment to the Company’s Restated Certificate of Incorporation to combine outstanding shares of the Company’s common stock, par value $0.0001 per share, into a lesser number of outstanding shares, by a ratio of not less than one-for-five and not more than one-for-thirty, with the exact ratio to be set within this range by the Company’s board of directors in its sole discretion. The results of the stockholders’ vote with respect to such approval were as follows:
| Votes For | Votes Against | Abstain | Broker Non-Votes |
|---|---|---|---|
| 111,115,503 | 2,752,862 | 117,502 | N/A |
The proposal to adjourn the Special Meeting, if necessary, to permit further solicitation and vote of proxies in the event that there was insufficient votes in favor of Proposal 1, was not acted upon at the Special Meeting since there was sufficient votes to approve Proposal 1.
