Key Financial Metrics

Note: All figures are in thousands unless otherwise noted. The filing text does not provide a specific margin percentage, but gross profit increased 13% year-over-year.

Material Changes Versus Prior Period

• Revenue Growth: Total revenue increased by 10% ($0.26 million), driven primarily by a 17% increase in grant and contract revenue ($1.64 million vs. $1.40 million). Product revenue remained relatively flat at $1.25 million.
• Increased Net Loss: The net loss widened by 33% to $11.02 million. This was primarily due to significant one-time charges:
  • Armor Exit Costs: $4.60 million impairment charge related to the decision to cease operations of the armor plant.
  • Reduction in Force: $0.41 million in severance and accrued vacation costs.
• Operating Expense Reductions: Despite the one-time charges, core operating expenses decreased. Research and Development (R&D) expenses dropped 40% to $5.20 million, and Sales and Marketing expenses fell 46% to $0.61 million.
• Derivative Liability Gains: Other income decreased by 41% to $3.02 million, largely due to a $2.8 million decrease in the change in fair value of derivative liabilities compared to the prior year.

Guidance, Outlook, and Risks

Management Commentary and Strategy

Management is executing a strategic pivot to focus exclusively on the medical device sector, leveraging silicon nitride for orthopedic and spinal applications. This shift involves exiting industrial applications, evidenced by the impairment of the armor plant and the sale of the TA&T subsidiary (closed February 2025). The company aims to commercialize AI-designed 3D-printed silicon nitride/PEEK implants.

Liquidity and Capital Resources

As of December 31, 2024, the company held $3.6 million in cash. Management initially expressed uncertainty regarding the ability to continue as a going concern. However, following a $5.0 million private placement closed in February 2025 (net proceeds ~$3.4 million), workforce reductions, and the sale of TA&T, management now believes it has sufficient liquidity to fund operations through at least March 19, 2026.

Risks and Contingencies

• Going Concern: While improved by the February 2025 financing, the company has a history of net losses and requires substantial future capital for R&D and commercialization.
• Regulatory Approval: Success depends on obtaining FDA clearance for new product candidates (e.g., joint replacements), which is costly, time-consuming, and uncertain.
• Market Acceptance: Silicon nitride products have experienced limited market acceptance to date. The company relies heavily on its partner, CTL Medical, for the sale of spinal fusion products.
• Intellectual Property: The company has no patent protection for the composition of matter for its solid silicon nitride, leaving it vulnerable to competitors creating similar formulations.
• NASDAQ Compliance: The company is subject to a "Mandatory Panel Monitor" regarding the $1.00 minimum bid price requirement. Failure to maintain this price for 30 consecutive days could result in delisting.

Investor Verification Checklist

• Post-Filing Capital Raise: Verify the closing details and net proceeds of the February 2025 private placement ($5.0 million gross) to confirm the extended runway to March 2026.
• TA&T Sale Completion: Confirm the finalization of the sale of Technology Assessment and Transfer, Inc. (TA&T) to Tethon Corporation and the assumption of liabilities.
• Product Pipeline Status: Review progress on FDA 510(k) or PMA submissions for new joint replacement and coated metal product candidates.
• Stock Price Compliance: Monitor the daily closing bid price to ensure it remains above the $1.00 threshold required to avoid NASDAQ delisting proceedings.
• Derivative Liability Valuation: Assess the volatility assumptions used in the Monte-Carlo models for warrant liabilities, as changes significantly impact reported net income/loss.
