A Single Customer Brings Energy Focus to Profitability
One buyer supplied nearly all third-quarter sales while U.S. lighting nearly vanished
Energy Focus finally made money. It just didn’t make it selling lighting.
The Solon, Ohio company reported third-quarter net income of $531,000 on revenue of $4.8 million. That one quarter beat the $3.6 million the company sold in all of 2025. Nearly all of it came from uninterruptible power supply (UPS) systems shipped to a single customer in Taiwan, part of the business Energy Focus now pitches for AI data centers.
One Customer Carried the Quarter
According to the 10-Q, a Taiwan buyer identified only as “Customer A” accounted for 95.8% of third-quarter sales and 95.3% of receivables. Taiwan revenue was $4.6 million. U.S. revenue was $200,000, down from $826,000 a year earlier.
Our readers will recognize the pattern. As we reported in August, second-quarter revenue tripled on energy storage sales to an Australian customer. That customer delivered $2.48 million in the second quarter and $1,000 in the third. Last year, a Taiwan UPS project played the same role. Each quarter brings a different big buyer, and so far none has come back.
In April, the company announced “Project Y,” a 2026 to 2027 contract with an Asian data center developer valued at about $6.6 million. The filing doesn’t say whether Customer A is that developer. If it is, roughly $2 million of the contract would be left for the next five quarters.
Where the Lighting Went
Navy sales, long the company’s anchor, fell to $71,000 from $1.49 million in the second quarter. The earnings release covered that drop in a “partially offset” clause.
Commercial lighting at home is harder to find. Through nine months, U.S. sales totaled $2.42 million and military maritime sales $2.19 million. If the Navy product ships domestically, our math from the filing’s country and product tables leaves about $227,000 of non-military U.S. revenue this year. This is a company that sold $64 million in 2015.
The footprint is shrinking to match. Energy Focus disposed of obsolete inventory that originally cost $1.4 million, cutting finished goods to $695,000 from $2.59 million at year-end. It wrote off $532,000 of fully depreciated equipment and leasehold improvements, sublet part of its Ohio warehouse and signed a short-term warehouse lease in California. The press release still calls the company “the creator of the first flicker-free LED lamps.”
The Profit Had Some Help
A refund of about $184,000 from U.S. Customs and Border Protection for previously paid duties was booked as a reduction to cost of goods sold. Without it, by our calculation, gross margin would have been about 16.7% rather than 20.5%, and net income closer to $347,000. That is still a profit. But one good quarter doesn’t rescue the year: through nine months, Energy Focus remains $486,000 in the red. The filing also doesn’t say which duties were refunded, a detail plenty of lighting importers would like to know.
The supply chain runs through the CEO. Winner Technology International, a Taiwan shareholder controlled by CEO Jay Huang, supplied 59% of third-quarter purchases and 65% year to date. Related parties account for 92.5% of accounts payable ($2.52 million) and 100% of open purchase commitments. The filing itself cites “potential conflicts of interest” and says the transactions are subject to approval by independent directors.
Cash rose to $3.3 million, helped by that unpaid balance to Winner, and $2.1 million of it sits in Taiwan, where the filing warns that moving it home could bring taxes or other costs. Huang still signs as both CEO and CFO. The going-concern warning remains, alongside a $156.4 million accumulated deficit and a Japan joint venture that still hasn’t closed.
A Polite Round of Applause
Investors noticed, briefly. The stock closed November 10 at $4.95, up 12.5%, on 182,000 shares, nearly eight times the prior day’s volume. It gave back 5.7% the next day to close at $4.67.
That’s a modest reaction to a profitable quarter, especially next to April’s one-day tripling. One reasonable reading is that the market sees a one-customer quarter as a one-off. Energy Focus hasn’t said what fourth-quarter revenue looks like. Until it does, the most important name in its business is Customer A, and that’s one name it hasn’t disclosed.
