(“Artal”), in the United States District Court for the Southern District of New York. The actions were consolidated and lead plaintiffs were appointed in June 2019. A consolidated amended complaint was filed on July 29, 2019, naming as defendants the Company, certain of the Company’s current officers and directors, and Artal and certain of its affiliates. A second consolidated amended complaint was filed on September 27, 2019. The operative complaint asserts claims on behalf of all purchasers of the Company’s common stock between May 4, 2018 and February 26, 2019, inclusive (the “Class Period”), including purchasers of the Company’s common stock traceable to the May 2018 secondary offering of the Company’s common stock by certain of its shareholders. The complaint alleges that, during the Class Period, the defendants disseminated materially false and misleading statements and/or concealed or recklessly disregarded material adverse facts. The complaint alleges claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 thereunder, and with respect to the secondary offering, under Sections 11, 12(a)(2), and 15 of the Securities Act of 1933, as amended.

In response to the demands, pursuant to Virginia law, the Board of Directors has created a special committee to investigate and evaluate the claims made in the demands. In addition, four derivative complaints were filed, each making allegations against certain of the Company’s officers and directors and/or Artal and certain of its affiliates. First, on June 13, 2019, a shareholder derivative complaint was filed in the Southern District of New York against certain of the Company’s officers and directors alleging, among other things, that the defendants breached fiduciary duties to the alleged injury of the Company.
