ADAP STOCK ALERT: HALPER SADEH LLC IS INVESTIGATING WHETHER THE MERGER OF ADAPTIMMUNE THERAPEUTICS PLC IS FAIR TO SHAREHOLDERS

March 6, 2023.

New York, New York—Halper Sadeh LLC, an investor rights law firm, is investigating whether the merger of Adaptimmune Therapeutics plc (NASDAQ: ADAP) and TCR² Therapeutics Inc. is fair to Adaptimmune shareholders. Under the terms of the agreement, TCR² stockholders will receive 1.5117 Adaptimmune ADS for each TCR² share. Following the closing of the transaction, Adaptimmune shareholders will own approximately 75% of the combined company.

The investigation concerns whether Adaptimmune and its board 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 Adaptimmune shareholders; and (2) disclose all material information necessary for Adaptimmune shareholders to adequately assess and value the merger consideration. On behalf of Adaptimmune shareholders, Halper Sadeh LLC may seek increased consideration for shareholders, additional disclosures and information concerning the proposed transaction, or other relief and benefits.
