SINTX Technologies Shares Q3 2021 Revenue Update

SALT LAKE CITY, Oct. 14, 2021 (GLOBE NEWSWIRE) - SINTX Technologies, Inc. (www.sintx.com) (NASDAQ: SINT) (“SINTX” or the “Company”), an original equipment manufacturer of advanced ceramics, announced today preliminary Q3 2021 revenue results and expectation of new Q4 2021 revenue from open orders of advanced ceramics prototypes.

Estimated revenue in Q3 2021 was approximately $240k which is more than the revenue in each of Q1 and Q2 2021 . Revenue came from three business areas, including monolithic silicon nitride for spinal implants and SN-PEEK for spinal implants, silicon nitride powder for an antipathogenic fabric application, and boron carbide torso plates for armor.

SINTX anticipates new revenue sources in Q4 with several open prototype orders we expect to fill with advanced silicon nitride for separate aerospace engine and rocket components, FleX SN powder for antipathogenic fabric, and an industrial boron carbide application.

SINTX continues to expand and gain momentum within the key areas of its business and looks forward to providing a business update following the release of the Quarterly Report on Form 10-Q for Q3 2021.
