Overview

The earnings call reveals mixed signals: declining gross margins and increased administrative expenses are concerning, while decreased R&D expenses and positive customer feedback on 5G products are promising. The Q&A highlights uncertainties in revenue projections and breakeven timelines, causing hesitance. Despite potential growth from satellite communications and FWA, lack of specific guidance tempers optimism. With cash reserves improving post-year-end, the overall sentiment remains balanced, leading to a neutral prediction.

Key Financial Performance

Net Revenues Decreased by $6.3 million or 69% from $9.1 million in 2024 to $2.9 million in 2025. The decline was due to a $3.6 million decrease in product sales and a $2.6 million decrease in service revenues. Lower product sales were driven by reduced 5G reference platform sales during the transition to 5G, while service revenue decreased due to the completion of a substantial service project in the prior year.

Cost of Net Revenue Increased by $0.6 million or 16% from $4.1 million in 2024 to $4.7 million in 2025. This increase was largely due to additional production overhead costs.

Gross Margin Negative for 2025, primarily due to insufficient product revenue to fully absorb production overhead costs. Margins are expected to improve as product volumes increase, particularly with the contribution of 5G chipset sales.

Research and Development Expenses Decreased by $3.3 million or 19% from $17.3 million in 2024 to $14 million in 2025. The decrease was largely due to the completion of a 5G chip design project, resulting in a $3.3 million reduction in professional services. This was partially offset by a $0.9 million increase in personnel-related costs, a $0.3 million increase in stock-based compensation, and a $0.4 million increase in preproduction and engineering supplies related to 5G initiatives.

Sales and Marketing Expenses Relatively flat year-over-year, totaling $3.9 million in 2024 compared to $4.2 million in 2025.

General and Administrative Expenses Increased by $5.7 million or 53% from $10.8 million in 2024 to $16.5 million in 2025. The increase was primarily due to changes in credit loss estimates for receivables, resulting in a $3.2 million net increase, a $3.2 million increase in stock-based compensation due to equity-classified common stock warrants issued in 2025, and a $0.6 million increase in personnel-related costs. These increases were partially offset by a $1.2 million decrease in professional services and other costs.

Stock-Based Compensation Expense Increased by $3.2 million from $2 million in 2024 to $5.2 million in 2025. The increase was primarily due to the issuance of equity-classified common stock warrants to investors in 2025.

Cash and Cash Equivalents Ended 2025 at $0.6 million. Subsequent to year-end, as of February 2026, cash and cash equivalents increased to $9.4 million.

Key Q&A

Q:Can you talk about the visibility from customers for fixed wireless access (FWA) ramps through the year and the potential material impact?
A:FWA remains an important vertical, with expectations to ship more into the market this year and growing backlog as early as Q2 for lead customers.
Q:When could revenues from satellite and ground air programs start to materialize, and to what extent?
A:Some products are already shipping for NTN applications, with new partner shipments expected in the second half of the year. This is seen as a significant vertical for 5G and 4G products.
Q:Can you size the trajectory of revenues through the year and provide insights on reaching $25 million for adjusted EBITDA breakeven?
A:Management finds it hard to provide specifics due to vague schedules. They anticipate reaching the $25 million breakeven point by Q1 2027, with more visibility expected in Q2 2026.
Q:How should we think about gross margins as revenues rise sequentially through the year?
A:Current gross margins are not representative of future potential. Management expects gross margins to reach high 30s to low 40s as product revenue matures and ramps up.
Q:What drove the sequential increase in operating expenses in Q4, and what is the outlook?
A:The increase was due to one-off events like balance sheet cleanup and issuing warrants to investors. These are not expected to continue into 2026, with G&A expenses normalizing to 2025 levels adjusted for inflation.
Q:What feedback have you received from customers about the 5G product?
A:Customers are satisfied with the product and its support for unique applications. It enables their solutions and provides options for future roadmaps, with expectations for additional revenue and volume growth.
Q:Can you quantify the potential business from the satellite communications company you signed a license with?
A:The potential is significant, with expectations of over 1 million units annually. Management believes they are the sole supplier for this application, though supply chain diversification is anticipated.
Q:How many customers did you ship to in Q4, and what is the expectation for Q1?
A:In Q4, shipments were made to three customers, with one being a named customer for commercialization. For Q1, shipments are expected to range from three to five customers.
Q:What is the expected G&A expense for Q1?
A:The normal run rate for operating expenses is expected to be around $8 million to $8.5 million per quarter, including Q1.
Q:What caused the supply limitations in Q4, and is it still an issue?
A:Supply limitations in Q4 were due to wafer availability and suboptimal testing throughput. Testing throughput has significantly improved in Q1, with further optimization planned.
Q:Review of Unclear Management Responses
A:Management avoided providing a clear trajectory for revenues through the year, citing vague schedules and lack of visibility. They also did not provide specific guidance on the material impact of FWA ramps or the exact timeline for reaching adjusted EBITDA breakeven.
