Exhibit 99.1

SINTX Technologies Engages Veteran MedTech Executive

Chris Lyons and Southern Metrics to Establish Strategic Opportunity Management Program

SALT LAKE CITY, Utah –

July 23, 2026 – SINTX Technologies, Inc. (NASDAQ: SINT) (“SINTX” or the “Company”), a leader in advanced

biomaterials and silicon nitride technologies for medical device and industrial applications, today announced that it has engaged Southern

Metrics Consulting (“Southern Metrics”) to assist the Company in identifying, evaluating, and pursuing strategic opportunities

intended to enhance stockholder value. Southern Metrics is led by Chris Lyons, its Chief Executive Officer, an experienced medical technology

executive and strategic advisor who has served on the SINTX Board of Directors since April 2025. Southern Metrics will establish and manage

the Company’s newly created Strategic Opportunity Management Program.

The Strategic Opportunity Management Program is designed

to provide a disciplined, proactive framework for identifying, evaluating, prioritizing, and managing strategic opportunities that support

SINTX’s long-term growth strategy and enhance stockholder value. Working closely with executive management and the Board of Directors,

Southern Metrics will assist the Company in evaluating a broad range of potential opportunities, including commercial partnerships, licensing

arrangements, strategic investments, joint ventures, acquisitions, divestitures, and other corporate development initiatives.

SINTX believes it has reached an important point in

its evolution from an advanced biomaterials development company toward a commercial-stage medical technology company. As interest in the

Company’s proprietary technology platform expands across orthopedic, spine, craniofacial, dental, suture, and wound-management applications,

SINTX believes a formal strategic process will help it evaluate opportunities consistently and efficiently.

“SINTX has reached an important stage in the

Company’s transformation,” said Eric K. Olson, Chairman and Chief Executive Officer of SINTX Technologies. “Over the

past year, we have expanded our commercial capabilities, advanced our proprietary technologies, strengthened our intellectual property

portfolio, and increased engagement with strategic participants throughout the medical technology industry. Our objective is straightforward:

to ensure that every strategic opportunity is evaluated through a disciplined, consistent, and stockholder-focused process. Chris has

spent more than three decades helping innovative medical technology companies navigate commercialization, strategic partnerships, and

corporate development initiatives, and we are pleased to leverage his expertise as we evaluate the next phase of the Company’s development.”

“I am excited to assist SINTX as it enters this

next stage of growth,” said Mr. Lyons. “Having served on the Board and worked throughout my career with emerging medical technology

companies, I believe SINTX has a compelling combination of differentiated technology, intellectual property, manufacturing capabilities,

and commercial potential. I look forward to bringing a disciplined, market-informed perspective to the Company’s strategic planning

and helping management and the Board identify opportunities that advance SINTX’s long-term objectives and create value for stockholders.”

Mr. Lyons will continue to serve as a member of SINTX’s

Board of Directors.

within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements regarding the

Company’s Strategic Opportunity Management Program; the identification, evaluation, and pursuit of strategic opportunities; potential

commercial partnerships, licensing arrangements, strategic investments, joint ventures, acquisitions, divestitures, and other corporate

value. Words such as “believe,” “expect,” “intend,” “plan,” “may,” “will,”

“should,” “could,” “seek,” “potential,” and similar expressions are intended to identify

forward-looking statements, although not all forward-looking statements contain these words.

These statements are based on management’s current

expectations and assumptions and are subject to risks and uncertainties that could cause actual results to differ materially from those

expressed or implied. These risks and uncertainties include, among others, the Company’s ability to identify suitable strategic

opportunities; the availability and terms of potential transactions or commercial arrangements; the willingness of potential counterparties

to engage with the Company; the Company’s ability to obtain necessary financing, regulatory approvals, third-party consents, or

The engagement of Southern Metrics does not indicate that any specific transaction or other corporate development initiative is pending
