Exhibit 99.1

Amedica Announces Delayed Filing of Annual Report on Form 10-K and Receipt of Nasdaq Letter

SALT LAKE CITY, April 19, 2017 – Amedica Corporation (Nasdaq:AMDA), an innovative biomaterial company which develops and manufactures silicon nitride as a platform for biomedical applications, announced today that it is delaying the filing of its Annual Report on Form 10-K for the year ended December 31, 2016 (“Form 10-K”).

On March 31, 2017, Amedica filed a Form 12b-25, Notification of Late Filing, with the Securities and Exchange Commission (the “SEC”) regarding its delayed Form 10-K. At that time, Amedica expected that it would be able to file the Form 10-K within the 15-day extension period provided by Form 12b-25. Amedica has subsequently determined that the Company will be unable to do so. The Company requires additional time to fully consider whether there is any potential impairment in relation to certain of its long-lived assets. Management and the Audit Committee of the Company’s Board of Directors are continuing to work diligently to complete its Annual Report on Form 10-K for the fiscal year ended December 31, 2016 and file it with the SEC as soon as possible.

Because the filing of the Company’s Form 10-K has been delayed beyond the 15-day extension period of Form 12b-25, on April 18, 2017, Amedica received a written notice from the Listing Qualifications Department of The Nasdaq Stock Market (“NASDAQ”) indicating that the Company is not in compliance with Listing Rule 5250(c)(1) because the Company has failed to file its Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Under the NASDAQ Listing Rules, the Company has 60 days from the receipt of the letter to submit a plan to NASDAQ as to how it plans to regain compliance with NASDAQ’s continued listing requirements. If the Company is still unable to file its Form 10-K by that time, then the Company intends to submit a compliance plan on or prior to that date. If NASDAQ accepts the Company’s plan, NASDAQ can grant an exception of up to 180 calendar days from the filing’s due date, or until September 27, 2017, to regain compliance. The Company may regain compliance at any time during this 180-day period upon filing with the SEC its Form 10-K, as well as all subsequent required periodic financial reports that are due within that period. If NASDAQ does not accept the Company’s plan, Amedica will have the opportunity to appeal that decision to a NASDAQ Hearings Panel.

The NASDAQ notification letter has no immediate effect on the listing of Amedica’s common stock on the NASDAQ Capital Market.
