Energy Focus (NASDAQ: EFOI) swings to profit as a new Taiwan UPS customer lifts sales

What happened

Energy Focus, Inc. (NASDAQ: EFOI) swung to a $0.5 million third-quarter net profit on higher sales to a new Taiwan customer. The gain rests on one new customer at a company that still warns of going-concern doubt.

Net sales were $4.8 million in the quarter ended Sept. 30, the company said Nov. 10. That is up 481.2% from $0.8 million a year earlier and 28.1% from $3.7 million in the second quarter. Earnings were $0.08 per share, against losses of $0.03 a year earlier and $0.14 in the second quarter.

Where the sales came from

Commercial products did the work. They brought in $4.48 million, which OptimistFi calculates at 93.2% of net sales. Commercial sales rose $4.3 million from a year earlier, a 2115.8% increase. The release ties the gain to growth in the uninterruptible power supply (UPS) business with a new customer in Taiwan.

That project included installation and setup services. Setup service revenue rose to $254 thousand from $4 thousand in the second quarter.

Military maritime product sales moved the other way. They were $71 thousand, down from $1.49 million in the second quarter and $621 thousand in the third quarter of 2025.

Margins and one-time items

Gross margin was 20.5%, up from 17.8% a year earlier and from a negative 6.8% in the second quarter. The release credits higher commercial sales from the UPS expansion and a better product mix.

A refund of about $184 thousand from U.S. Customs and Border Protection for duties previously paid also cut cost of goods sold and helped gross profit. That refund is a one-time item, not operating improvement.

The quarter also carried $802 thousand of inventory charges. They were $246 thousand of reserve provisions and $556 thousand of write-offs for obsolete inventory. Without them, adjusted gross margin was 37.2%, against 27.2% a year earlier and 4.5% in the second quarter. Operating income turned positive after a loss of $0.2 million a year earlier and a loss in the second quarter.

Cash and borrowings

Cash was $3.3 million on Sept. 30, up from $1.1 million at Dec. 31, 2025 and $0.9 million a year earlier. The release attributes the rise mainly to short-term borrowings and a timing gap.

Some customer payments had arrived while the related supplier payments were still owed. The balance sheet shows the other side. Accounts payable to a related party were $2.52 million, up from $386 thousand at year-end. Total current liabilities were $4.15 million, up from $922 thousand.

Net cash from operations was $1.5 million for the nine months, even though the company still posted a net loss for that period.

Why it matters

OptimistFi has argued that Energy Focus must turn its products into real orders before cash needs catch up with it. The quarter shows one line, UPS, doing that. The view stays mixed because the military maritime business shrank in the same period.

The release itself supplies the caveat. It cites a need for more financing and substantial doubt about continuing as a going concern. It also names dependence on private placements with related parties and reliance on a limited number of customers, including single large projects.

The release calls the new customer relationship early stage, with no assurance of long-term partnership or material revenue.

What's next

The next test is Energy Focus's next quarterly report. Commercial sales holding near this quarter's level would show the Taiwan UPS business is more than a one-time project. A fall back toward last year's $202 thousand would weaken the case.

That report will also show whether military maritime sales recover from this quarter's low. It will show whether the $911 thousand of short-term borrowings and the related-party payables shrink or grow.
