In addition, the SEC has subpoenaed documents and testimony from each of the Company and its General Counsel. Each of the SEC subpoenas is captioned “In the Matter of Trading in the Securities of Sientra, Inc.” The SEC subpoenas request, among other things, documents and communications relating to trading activities by each of the aforementioned individuals. The investigation by the SEC does not mean that the SEC has concluded that anyone has violated the law.
