SINTX TECHNOLOGIES RENEWS LEASE WITH PORTFOLIO INVESTMENTS AT CENTREPOINTE BUSINESS PARK

SALT LAKE CITY, Utah (June 10, 2019) — SINTX Technologies, Inc., a ceramics OEM company that develops and manufactures silicon nitride, announced today that the Company renewed its lease with Portfolio Investments at Centrepointe Business Park in Salt Lake City, Utah, for a five year term. SINTX has been at this location since 2009. The Company will lease a smaller section of the building consistent with a new footprint following the sale of its retail spine business and re-branding last year.

Dr. Sonny Bal, President & CEO, said “This is a milestone for SINTX. We have right-sized our operations, and the significant cost savings from the building lease will allow SINTX to focus on scaling up our manufacturing, and invest further in R&D activities.”

“We are excited to remain in Salt Lake City, a technology hub,” Dr. Bal added. “The company was founded here in 1996. Our first silicon nitride spinal device was implanted at the University of Utah in 2008. We have long-standing relationships with the University’s Bone & Joint Laboratory and Nanofab facility. We look forward to growing our company in Utah.”

Centrepointe Business Park is located in proximity of the Salt Lake City International Airport and is within minutes of downtown Salt Lake City. Corey Brand of Centrepoint said “SINTX has been a great tenant and we look forward to the next five years with them.”

SINTX was represented in the transaction by Travis Yates of Colliers International.
