"We believe SINTX is entering a new phase defined by commercialization and operational momentum," said Eric K. Olson, Chairman and Chief Executive Officer of SINTX Technologies. "The work completed in 2025 has created a strong foundation for the Company to move into an execution-driven phase, where our focus is on expanding market access, building commercial relationships, and translating our differentiated technology into measurable business results. Importantly, we are continuing to evolve SINTX into a platform-driven biomaterials company with multiple potential revenue pathways."

"On March 13, 2026, SINTX achieved a significant clinical milestone with the first human procedure utilizing its SINAPTIC Foot & Ankle Osteotomy Wedge System. The system received U.S. Food and Drug Administration (FDA) 510(k) clearance in October 2025 and represents the Company's entry into the foot and ankle reconstruction market," stated Lisa Marie Del Re, Chief Commercial Officer. "SINTX believes this milestone supports its planned commercial rollout and increased surgeon engagement, while further validating silicon nitride as a differentiated biomaterial for orthopedic implants."

The global foot and ankle reconstruction market represents a significant market opportunity, and the Company believes its silicon nitride technology offers differentiated characteristics—including bone affinity, imaging compatibility, and surface properties studied for resistance to bacterial adhesion—that may support broader adoption across orthopedic applications.

In parallel with this clinical progress, Ryan Elmore began work this past week as President of SINTX Technologies, bringing more than 15 years of experience in advanced biomaterials and medical device commercialization, including prior leadership roles at Invibio, a division of Victrex plc. He is expected to lead execution of the Company's commercial strategy, including channel development, surgeon engagement, OEM relationships, and strategic partnerships.

"SINTX has already established a strong technical and clinical foundation," said Ryan Elmore. "Our focus now is execution—accelerating commercialization, expanding market access, and building scalable revenue opportunities across the Company's silicon nitride platform." Management believes Mr. Elmore's experience in scaling biomaterials businesses and building global commercial channels will be instrumental in advancing adoption of SINTX's technologies.

As part of its ongoing transition toward advanced manufacturing, SINTX has recently acquired new equipment and expanded its technical team with key hires focused on additive and advanced processing technologies. The Company is actively evolving from traditional subtractive ceramic manufacturing toward more scalable, digitally enabled production methods, including AI-assisted 3D manufacturing. SINTX anticipates that this transition may support improved design flexibility, faster development cycles, and expanded collaboration opportunities, and expects to pursue additional partnership agreements aligned with these capabilities. While these initiatives are ongoing, management believes they represent an important component of the Company's long-term manufacturing and commercialization strategy.

Beyond monolithic implants, SINTX continues to advance its silicon nitride technology across multiple material formats, including powders, coatings, porous structures, and composite materials such as SiN/PEEK and SiN/PEKK. The Company believes this platform supports multiple high-value applications across orthopedic implants, spine, foot and ankle, dental, and other specialized medical markets.

In addition to these applications, SINTX is advancing its broader strategy to position silicon nitride as an infection-resistant biomaterials platform. As part of these efforts, the Company has initiated preclinical animal studies evaluating the incorporation of silicon nitride into sutures, meshes, and wound care materials. These studies are intended to further explore the material's surface properties and potential applicability in soft tissue and wound management environments. SINTX believes it will finalize preclinical data in the second half of 2026 which will support future opportunities to expand beyond traditional implantable devices into a broader range of medical and biomaterial applications.

In parallel, SINTX is advancing multiple supply formats—including filament, rod, and sheet configurations—to support partner evaluation and commercialization across both additive and traditional manufacturing workflows.

SINTX believes its intellectual property portfolio remains a core strategic asset supporting long-term growth. As disclosed in its most recent Annual Report on Form 10-K, the Company maintains a broad patent estate across multiple jurisdictions, including recent expansion into antipathogenic applications such as fibrous materials and related methods. The Company has also received multiple NIH grants supporting development of 3D-printed silicon nitride/polymer implantable medical devices.

Looking ahead, SINTX is focused on expanding surgeon adoption of its SINAPTIC Foot & Ankle System, focusing on "personalized" custom and patient specific implants, developing U.S. distribution and channel partnerships, advancing OEM and private-label opportunities, and pursuing strategic collaborations related to silicon nitride composites and additive manufacturing. Management believes these initiatives, combined with the Company's clinical progress, manufacturing capabilities, leadership expansion, and platform strategy, position SINTX to pursue multiple revenue pathways, including direct product commercialization, OEM supply, licensing, and co-development partnerships.

"We believe SINTX is uniquely positioned as a platform-driven biomaterials company with multiple avenues for growth," added Olson. "Our focus is on building commercial momentum, expanding market access, and translating our differentiated technology into measurable business results."
