Formation and Business of the Company

(1) Formation and Business of the Company

(a) Formation

Sientra, Inc. (“Sientra”, the “Company,” “we,” “our” or “us”), was incorporated in the State of Delaware on August 29, 2003 under the name Juliet Medical, Inc. and subsequently changed its name to Sientra, Inc. in April 2007. The Company acquired substantially all the assets of Silimed, Inc. on April 4, 2007. The purpose of the acquisition was to acquire the rights to the silicone breast implant clinical trials, related product specifications and pre-market approval, or PMA, assets. Following this acquisition, the Company focused on completing the clinical trials to gain FDA approval to offer its silicone gel breast implants in the United States.

In March 2012, the Company announced it had received approval from the FDA for its portfolio of silicone gel breast implants, and in the second quarter of 2012 the Company began commercialization efforts to sell its products in the United States. The Company, based in Santa Barbara, California, is a medical aesthetics company that focuses on serving board-certified plastic surgeons and offers a portfolio of silicone shaped and round breast implants, scar management, tissue expanders, and body contouring products.

In November 2014, the Company completed an initial public offering, or IPO, and its common stock is listed on the Nasdaq Stock Exchange under the symbol “SIEN.”

(b) Acquisition of miraDry

On June 11, 2017, Sientra entered into an Agreement and Plan of Merger, or the Merger Agreement, with miraDry (formerly Miramar Labs), pursuant to which Sientra commenced a tender offer to purchase all of the outstanding shares of miraDry’s common stock for (i) $0.3149 per share, plus (ii) the contractual right to receive one or more contingent payments upon the achievement of certain future sales milestones. The total merger consideration was $18.7 million in upfront cash and the contractual rights represent potential contingent payments of up to $14 million. The transaction, which closed on July 25, 2017, added the miraDry System to Sientra’s aesthetics portfolio.

(c) Acquisition of certain assets from Vesta Intermediate Funding, Inc.

On November 7, 2019, the Company entered into an Asset Purchase Agreement, or the Purchase Agreement, with Vesta Intermediate Funding, Inc., or Vesta, pursuant to which the Company purchased certain assets and obtained a non-exclusive, royalty-free, perpetual, irrevocable, assignable, sublicensable, and worldwide license to certain intellectual property owned by Vesta, or the Vesta Acquisition. The total consideration was $ 19.1 million in cash, $3.2 million and $3.0 million in cash payable on November 7, 2021 and November 7, 2023, respectively, and two contingent share issuances of up to 303,721 shares each, of the Company’s common stock upon the achievement of certain price targets. The transaction, which closed on November 7, 2019, will allow the Company to achieve a greater degree of vertical integration, obtaining direct control of breast implant manufacturing and product development activities and generating production-related cost synergies.

(d) Regulatory Review of Vesta Manufacturing

Prior to its acquisition, the Company engaged Vesta for the manufacture and supply of the Company’s breast implants. On March 14, 2017, the Company announced it had submitted a site-change pre-market approval, or PMA, supplement to the FDA for the manufacture of the Company’s PMA-approved breast implants at the Vesta manufacturing facility. On January 30, 2018, the Company announced the FDA has granted approval of the site-change supplement for Vesta to manufacture its silicone gel breast implants. In support of the move to the Vesta manufacturing facility, the Company also implemented new manufacturing process improvements which, in consultation with the FDA, required three (3) additional PMA submissions.  In addition to approving the manufacturing site-change PMA supplement, the FDA approved the Company’s three (3) process enhancement submissions on January 10, 2018, January 19, 2018 and April 17, 2018.

(e) Follow-on Offerings

On May 7, 2018, the Company completed an underwritten follow-on public offering of 7,407,408 shares of its common stock at $13.50 per share, as well as 1,111,111 additional shares of its common stock pursuant to the full exercise of the over-allotment option granted to the underwriters. Net proceeds to the Company were approximately $107.6 million after deducting underwriting discounts and commissions of $6.9 million and offering expenses of approximately $0.5 million.

On June 7, 2019, the Company completed an underwritten follow-on public offering of 17,391,305 shares of its common stock at $5.75 per share, as well as 2,608,695 additional shares of its common stock pursuant to the full exercise of the over-allotment option granted to the underwriters. Net proceeds to the Company were approximately $107.7 million after deducting underwriting discounts and commissions of $6.9 million and offering expenses of approximately $0.4 million.

(f) Regulatory Inquiries Regarding Products Manufactured by Silimed

There have been regulatory inquiries related to medical devices manufactured by Silimed Indústria de Implantes Ltda. (formerly, Silimed-Silicone e Instrumental Medico-Cirugio e Hospitalar Ltda.), or Silimed, the Company’s former sole source contract manufacturer for its silicone gel breast implants. Following extensive independent, third-party testing and analyses of its devices manufactured by Silimed, which tests indicated no significant safety concerns with the use of Silimed’s products, the Company lifted the temporary hold on the sale of such devices. While the Company continues to sell its remaining inventory of devices manufactured by Silimed, its existing manufacturing contract with Silimed expired on its terms in April 2017 and the Company did not renew the contract.
