Corporate Update: Progress and Strategic Vision

I am pleased to provide you with a year-end update on the current state of SINTX Technologies, Inc., our progress over the past months, and the strategic steps we are taking to position the company for growth and long-term value creation. Transparency and open communication remain a cornerstone of our relationship with shareholders, and I hope this detailed update reflects our commitment to keeping you informed.

Refocusing on Medical Device Innovation

As detailed in our recent filings, SINTX Technologies is undergoing a strategic transformation to refocus on the medical device sector, building on our legacy of innovation in silicon nitride technology. We believe this refined direction best aligns with the company's strengths and the significant market opportunities in healthcare. Our aim is to provide advanced solutions in orthopedics, spinal fusion, and infection control, leveraging our proprietary materials to address pressing needs in patient care.

Leadership Changes to Strengthen Strategic Execution

In alignment with this refocus, we are excited to announce that Gregg R. Honigblum has been appointed as our Chief Strategy Officer. Gregg brings an extensive track record of success, including securing over $100 million in funding for SINTX and its predecessor company, Amedica. His role will encompass fund raising initiatives, investor relations, and refining our corporate strategy. With Gregg's leadership, we are confident in our ability to strengthen SINTX's financial health and operational focus.

Financial Position and Operational Efficiency

SINTX's latest financial disclosures contained in the Quarterly Report (10-Q) ended September 2024, highlight our ongoing efforts to reduce costs and streamline operations. As of our most recent filing, the company holds approximately $5 million in cash and cash equivalents. While revenue generation remains a challenge, we have successfully identified opportunities to reduce our lease liabilities and optimize our operational footprint, including active negotiations to reduce our lease liability.

In addition, we have initiated a stock buyback program to repurchase up to $500,000 dollars (20% of outstanding common shares), reflecting our confidence in the company's future and our commitment to enhancing shareholder value.

Exploring Transformative Opportunities

We continue to evaluate strategic transactions, including potential reverse merger candidates within the medical device sector. This initiative aims to identify partners or acquisition targets that align with SINTX's strategic vision while maximizing value for shareholders.

Engagement with Management

At SINTX, we believe in fostering an open dialogue with our shareholders. If you have any questions regarding the information shared in this update, or about any of our recent press releases or public filings, we encourage you to reach out directly to our management team.

Looking Ahead

2024 has been a year of strategic realignment, and while challenges remain, we are optimistic about the road ahead. Our efforts to reposition SINTX Technologies within the medical device sector, reduce costs, and explore growth opportunities demonstrate our commitment to driving value for all stakeholders.

On behalf of the Board of Directors and the entire SINTX team, I thank you for your continued trust and support. We are excited to share further updates at the Shareholders Meeting and to engage with you as we build a stronger future together.
