Material Changes vs. Prior Period
- Revenue Decline: Net sales decreased 55% to $6.3 million, driven by a ~40% drop in sales to the largest U.S. Tier-1 telecommunications customer and a 78% decline in international sales due to geopolitical factors and project delays.
- Gross Loss: The company shifted from a gross profit of $1.3 million in 2024 to a gross loss of $3.2 million in 2025. This was primarily caused by a $1.967 million inventory write-down to net realizable value, increased factory overhead absorption due to underutilization, and a $455,000 impairment of right-of-use assets and lease deposits.
- Liquidity Deterioration: Working capital turned negative ($262k deficit) from a positive $7.0 million in 2024. Cash on hand dropped to $200k.
- Customer Concentration: While 88% of sales remained in telecommunications, the largest single customer accounted for 65% of total net sales in 2025, up from 48% in 2024.
Guidance, Outlook, Risks, and Contingencies
Going Concern Warning
Management has raised substantial doubt about the company's ability to continue as a going concern within one year of the report date. This is due to the net loss of $9.1 million, negative operating cash flow of $1.1 million, and significant liquidity constraints.
Material Risks and Contingencies
- Eviction Risk: The company is delinquent on rent for its Gardena, California headquarters and manufacturing facility. An eviction summons was filed in October 2025 but paused in February 2026 for negotiations. Failure to resolve this could halt operations.
- Debt Covenant Default: The company was not in compliance with the minimum Effective Tangible Net Worth covenant ($6,000k required vs. $755k attained) under its Pinnacle Bank credit facility. A Forbearance Agreement was executed in March 2026, allowing operations to continue until July 31, 2026, contingent on specific payments and account assignments.
- Financing Needs: The company is actively raising capital through an At-The-Market (ATM) equity offering. As of April 15, 2026, it had raised approximately $3.2 million in net proceeds from ATM sales in 2025 and early 2026.
- Backlog: Sales backlog as of December 31, 2025, was $4.3 million, with 82% attributed to telecommunications customers. Management expects shipment within 6-12 months.
Investor Verification Checklist
- Lease Resolution: Verify the status of negotiations with landlords for the Gardena facilities and confirm if a payment plan has been finalized to prevent eviction.
- Debt Compliance: Confirm the company's ability to meet the July 31, 2026, deadline under the Pinnacle Bank Forbearance Agreement to avoid foreclosure on collateral.
- ATM Offering Progress: Monitor the pace of share sales under the ATM facility and the weighted average price to assess dilution and capital sufficiency.
- Inventory Valuation: Review the assumptions used for the $1.967 million inventory write-down and assess the risk of further write-downs if demand does not recover.
- Customer Diversification: Evaluate progress in reducing reliance on the single largest customer (65% of sales) and the success of international market expansion.
