TCRR STOCK ALERT: HALPER SADEH LLC IS INVESTIGATING WHETHER THE SALE OF TCR² THERAPEUTICS INC. IS FAIR TO SHAREHOLDERS

March 6, 2023.

New York, New York—Halper Sadeh LLC, an investor rights law firm, is investigating whether the sale of TCR² Therapeutics Inc. (NASDAQ: TCRR) to Adaptimmune Therapeutics plc for 1.5117 Adaptimmune ADS for each TCR² share is fair to TCR² shareholders. Following the closing of the transaction, TCR² stockholders will own approximately 25% of the combined company.

The investigation concerns whether TCR² and its board of directors violated the federal securities laws and/or breached their fiduciary duties to shareholders by failing to, among other things: (1) obtain the best possible consideration for TCR² shareholders; (2) determine whether Adaptimmune is underpaying for TCR²; and (3) disclose all material information necessary for TCR² shareholders to adequately assess and value the merger consideration. On behalf of TCR² shareholders, Halper Sadeh LLC may seek increased consideration for shareholders, additional disclosures and information concerning the proposed transaction, or other relief and benefits.
