• Do you, or did you, own shares of Sientra, Inc. (NASDAQ GS: SIEN)?
• Did you purchase your shares between March 18, 2015 and September 24, 2015, inclusive?

Rigrodsky & Long, P.A. announces that a complaint has been filed in the United States District Court for the Central District of California on behalf of all persons or entities that purchased the common stock of Sientra, Inc. (“Sientra” or the “Company”) (NASDAQ GS: SIEN) between March 18, 2015 and September 24, 2015, inclusive (the “Class Period”), alleging violations of the Securities Exchange Act of 1934 against the Company and certain of its officers (the “Complaint”).

If you purchased shares of Sientra during the Class Period, or purchased shares prior to the Class Period and still hold Sientra, and wish to discuss this action or have any questions concerning this notice or your rights or interests, please contact Timothy J. MacFall, Esquire or Peter Allocco of Rigrodsky & Long, P.A., 2 Righter Parkway, Suite 120, Wilmington, DE 19803 at (888) 969-4242; by e-mail to info@rl-legal.com; or at: http://rigrodskylong.com/investigations/sientra-inc-sien.

The Complaint alleges that throughout the Class Period, defendants made materially false and misleading statements, and omitted materially adverse facts, about the Company’s business, operations and prospects. As a result of defendants’ alleged false and misleading statements, the Company’s stock traded at artificially inflated prices during the Class Period.

According to the Complaint, on September 24, 2015, it was announced that the United Kingdom’s Medicines and Healthcare Products Regulatory Agency (“MHRA”) had suspended sales of Silimed products after an audit of Silimed’s manufacturing processes revealed contamination in Silimed’s Rio de Janeiro manufacturing plant. Headquartered in Brazil, Silimed is the exclusive manufacturer of Sientra’s products and is the largest manufacturer of silicone implants in South America.

On this news, shares in Sientra dropped over 52%, closing at $9.70 per share on September 24, 2015, on heavy trading volume.

If you wish to serve as lead plaintiff, you must move the Court no later than November 24, 2015. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation. Any member of the proposed class may move the court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.
