We are a clinical stage biotechnology company focused on developing new medicines to treat and cure patients with solid tumors. Turnstone Biologics Inc. was incorporated as a Canadian corporation on March 27, 2014. On December 13, 2018, we incorporated Turnstone Biologics Corp., a corporation under the laws of the State of Delaware. On December 14, 2018, we completed a reorganization from Canada to the United States, which we refer to as the Reorganization. In connection with the Reorganization, all of the shareholders of Turnstone Canada exchanged their shares in Turnstone Canada for shares of our new incorporated Delaware entity, as a result of which Turnstone Canada became our wholly owned subsidiary. Our principal executive offices are located at 9310 Athena Circle, Suite 300, La Jolla, California.
