Lantronix shares rose 6.3% to $6.02 on Thursday. The annual filing offers a less dramatic picture: revenue fell 1.6% to $120.9 million, while the loss narrowed to $4.2 million from $11.4 million.
The improvement came alongside a revenue decline. Gross profit rose 2.4%, operating cash flow climbed 35.6% to $9.9 million, and cash ended the year at $60.5 million. But the balance-sheet jump was mostly financed by selling equity, while the sales line still moved backward.
Management says the margin improvement came from what the business sold, not from a broad sales expansion. The company also spent less on research and development after restructuring its engineering team.
"Gross profit as a percentage of revenue (referred to as “gross margin”) increased primarily because of our product sales mix."

That mix lifted gross margin to 43.8% from 42.1%. Lantronix said the year also included a higher share of software and services revenue, plus the absence of lower-margin Gridspertise revenue. That helped gross profit grow even as total revenue declined.
The expense side did more of the work below gross profit. Research and development fell 5.6% to $17.6 million, and the company said the reduction in operating expenses was the main reason its net loss shrank.
"The decrease in net loss was primarily driven by the reduction in operating expenses of $5,656,000 combined with the increase in gross profit for fiscal 2026 compared to fiscal 2025."

The result was an operating margin of negative 3.4%, up from negative 8.9%. That is a meaningful change in the income statement, but it came alongside a revenue base that remains below the $160.3 million reached in fiscal 2024. Lantronix has reduced the cost structure faster than it has rebuilt the top line. Corporate arithmetic is often less glamorous than the product brochure.
Cash generation also improved, though the sources matter. Operating cash flow was $9.9 million, while financing activities supplied $31.1 million, primarily from $44.1 million of equity offerings, partly offset by debt-related payments and employee tax withholdings. Diluted shares rose 4.0% to 40.1 million.
The cash balance therefore says two things at once: Lantronix finished with more liquidity, and shareholders funded much of the increase. Net cash was $11.4 million at the latest annual measurement, with an enterprise value of $221.0 million and EV-to-sales of 1.8 times.
The company’s product disclosures provide a specific place to look for the sales question. Lantronix said software and services revenue increased on higher SaaS solutions in the Americas and EMEA, while IoT System Solutions revenue fell because of reduced Gridspertise sales. Its next annual report will need to show whether that mix shift is still expanding and how much of the lost system-solutions revenue has returned.
What Lantronix has not answered is whether the improved margins can continue without another year of lower revenue or fresh equity financing.
