SemiLEDS Corporation (LEDS)

SemiLEDs develops, manufactures and sells light emitting diode chips and the components, modules and systems built from them. The light goes into general lighting and into specialty industrial work: ultraviolet curing of polymers, light therapy in medical and cosmetic uses, counterfeit detection, germicidal and viricidal devices, horticulture, architectural lighting and entertainment lighting. Its own design is a vertical chip. Thin crystalline layers of gallium nitride are grown on a sapphire wafer, a mirror-like silver layer and then a copper alloy layer are laid on top, and the sapphire is lifted off with a laser and recycled for the next run. The argument for the design is heat: the copper alloy carries heat out to the packaging and the heat sink, so the chip runs cooler and holds its performance. Packaged products fall into ultraviolet, multi-channel emitter, automotive and specialty lighting groups, the ultraviolet range running from two to 260 electrical watts. 1819202122

Most of what the company sold in fiscal 2025 was not a light emitting diode at all. It took buy-sell purchase orders, buying equipment and reselling it: 38 million dollars of revenue against 36.5 million dollars of cost. Those other revenues were 94 percent of the year's total. The filing says the significant majority of revenue came from the purchase and sale of equipment from vendors in China. Because the trade carries so little margin, gross profit came to 6 percent of revenue, against 20 percent the year before on a far smaller base. 23242526

The buyers are few. The ten largest customers were 99 percent of revenue in fiscal 2025, up from 91 percent, and the three largest 94 percent, up from 61 percent. Two customers carried the equipment trade, 89 percent of the buy-sell revenue between them. In the concentration table the largest, called Customer A, was 59 percent of the year's revenue and Customer B 30 percent, where a year earlier neither had bought anything at all; Customer A was also 91 percent of what the company was owed at the year end. By billing address the money comes from a handful of countries: India, Japan, the Netherlands and the United States together were 97 percent of revenue, up from 78 percent, while customers in Taiwan and China including Hong Kong fell to 0.5 percent from 14 percent. Products reach them through a direct sales force and distributors, with packagers buying chips and reselling them on. 27282930313233

Manufacturing sits in Taiwan, and it has been too large for the work for a long time: the company says it has suffered from underutilization of its capacity since late 2011, primarily for LED chips, with equipment idled and significant excess capacity charges to show for it. The answer has been to go fabless, meaning it hires foundry fabs to make chips to its own design, while it looks for buyers for the chip making equipment it no longer runs. It still packages chips itself, chip bonding, wire bonding, phosphor coating, encapsulation, scribing, dicing and testing, and it uses contract manufacturers for some products and some steps. Raw materials come from suppliers around the world, with two or more sources for a majority of them, and the filing says it has never had a significant delay or shortage. 3435363738

The listed company is a Delaware corporation, incorporated on January 4, 2005, and a holding company for the Taiwan business. It reports in United States dollars under United States accounting rules, while the working currency of the operating subsidiary is the New Taiwan dollar, so translated figures move with the exchange rate. The rate used at the close of fiscal 2025 was 30.59 New Taiwan dollars to one United States dollar. 33940

The specifics

The audit report carries a going concern paragraph. Losses from operations ran to 1.6 million dollars in fiscal 2025 and 2.9 million the year before, and by the end of the year the accumulated deficit reached 190 million dollars against cash and equivalents of 2.6 million. Those facts, the filing says, raise substantial doubt about the company's ability to continue as a going concern. Management sets a liquidity plan against them: cost reductions and higher margin products, steady growth of module products and continued commercial sales of ultraviolet LEDs, more buy-sell equipment orders, and raising cash through possible equity offerings, asset sales or debt. The filing adds that there is no assurance the plan will be carried out. 4142434445

The listing has been in question too. On December 4, 2024 Nasdaq told the company it did not meet the 2.5 million dollar minimum stockholders' equity for continued listing; a plan was submitted, accepted, and given up to 180 calendar days. On February 28, 2025 the company repaid 1,200,000 dollars and 400,000 dollars of loan principal by handing shares to Simplot Taiwan Inc. and Trung Doan, which lifted equity back above the line, and Nasdaq sent a conditional compliance letter on April 17, 2025. Those loans come from the inside: secured agreements signed on January 8, 2019 with the chairman and chief executive and with J.R. Simplot Company, the largest shareholder, for 1.7 million dollars and 1.5 million dollars at an annual interest rate of 8 percent, secured by a second priority interest in the headquarters building and extended year after year. 464748

What it owns and who it faces. At the end of fiscal 2025 it held 81 patents issued and 10 pending in the United States and 97 issued and 11 pending elsewhere; of the 178 issued, 116 expire between 2026 and 2030. The company says its people, its product development and its trade secrets matter more to its position than the patents do. It has trademarks on SemiLEDs in the United States and MvpLED in China. The filing names no competitor at all: it says only that it competes with many LED chip and packaging makers, many of them much larger, with well funded private companies developing rival products, and with smaller entrants, some of them helped by government incentives and subsidies. A patent cross-license agreement with CrayoNano AS pays it money, and those payments fell in fiscal 2025. 4950515253

Two other threads run through the filing. Through its subsidiary TSLC Corporation the company owns 47.62 percent of Yi Yang Optoelectronics Co., Ltd. and accounts for it by the equity method; its share of that company's losses grew to 958 thousand dollars in fiscal 2025 from 3 thousand the year before. And it is working with a Japanese company on sensors for smartphones, smartwatches and augmented and virtual reality glasses, using a wafer level package that joins photonic devices to photodetectors and driver chips in one thin package without an interposer. There were no material pending legal proceedings at the end of fiscal 2025. 54555657

What drives growth, line by line

Revenue was 43.0 million dollars in fiscal 2025 against 5.2 million the year before, a rise of 730 percent, and the filing credits it almost entirely to 38 million dollars of buy-sell equipment orders. The record's own series shows how far outside the pattern that sits: revenue of 6.1 million in 2020, 4.7 million in 2021, 7.1 million in 2022, 6.0 million in 2023 and 5.2 million in 2024. Gross profit rose to 2.4 million from 1.1 million, but measured against revenue it fell to 6 percent from 20 percent. 58592326

Other revenues. The line that is not a product, and now the business: other revenues were 41 million dollars in fiscal 2025 against 2 million the year before, and the filing says the increase came primarily from buy-sell purchase orders of equipment. The mechanics are plain: the company buys equipment and resells it, 38 million dollars of revenue for 36.5 million dollars of cost. A year earlier the same line was mostly epitaxial wafers, scraps and raw materials and services. 602361

LED components. LED components, the core product until this year, brought in 2.0 million dollars against 2.7 million, a fall the filing puts down to less volume sold. Their share of revenue dropped from 51 percent to 5 percent, not because they shrank that far but because the equipment trade swamped them. Setting the buy-sell orders aside, the company says it expects to go on earning its revenue mainly from LED components. 6263

LED chips. LED chips are now a rounding error in the company's own accounts: 149 thousand dollars against 93 thousand, which the filing attributes to varying volumes sold. It makes fewer of them itself each year, having moved toward a fabless model and gone looking for buyers for its chip making equipment. 6435

Lighting products. Lighting products, the luminaires and retrofits it assembles for design manufacturers and end users, were 228 thousand dollars against 212 thousand, again on varying volumes sold. 6566

What comes next, in the company's own words: it anticipates more buy-sell purchase orders in fiscal 2026, and says in the same breath that if those orders diminish or cease altogether its gross margin, operating results and cash flows could be hurt. Its liquidity plan puts steady growth of module products and continued commercial sales of its ultraviolet LED products behind a better gross margin, with niche markets and new applications for the LED products as the route. 676843

What the desk infers Inferred

1. Inferred

   The equipment orders that produced nearly all of fiscal 2025's revenue are a pass-through trade rather than a product business: machines bought from vendors in one country and billed on to a buyer in another, with a thin slice kept.

   Because

   • The buy-sell orders brought 38 million dollars of revenue and carried 36.5 million dollars of cost. 23
   • The filing says the significant majority of the year's revenue came from the purchase and sale of equipment from vendors in China. 24
   • By billing address, revenue from India went from nothing to 38 million dollars. 6923
   • Gross profit fell to 6 percent of revenue from 20 percent, which the filing lays at the door of the equipment orders and their lower margins. 26
   Confidence 88 of 100Wrong if A filing showing that the company designs, makes or materially alters the equipment it resells, or that the buy-sell orders earn the same gross margin as its LED products.
2. Inferred

   Customer A is far more likely a buyer of the resold equipment than of LED products, and the company's ability to collect now rests on that one account.

   Because

   • Customer A was 59 percent of revenue in fiscal 2025 and Customer B 30 percent, where a year earlier neither bought anything. 29
   • Two customers accounted for 89 percent of the buy-sell equipment revenue. 28
   • The largest product line, LED components, brought only 2.0 million dollars, while the equipment orders brought 38 million. 6223
   • Customer A was 91 percent of the company's accounts receivable at the end of fiscal 2025, having been none of it a year earlier. 30
   • A bad debt expense of 115 thousand dollars appeared where there had been none. 70
   Confidence 80 of 100Wrong if A filing or disclosure naming Customer A as a buyer of LED chips, components or lighting products in fiscal 2025.
3. Inferred

   The LED business on its own does not cover the cost of running the company, which is why the equipment trade sits inside the liquidity plan rather than beside it.

   Because

   • The product lines brought 2.0 million dollars of LED components, 149 thousand of chips and 228 thousand of lighting products. 626465
   • Research and development was 1.2 million dollars and selling, general and administrative 2.9 million, against a loss from operations of 1.6 million. 717241
   • The liquidity plan lists growing buy-sell purchase orders of equipment among the measures meant to keep the company going. 44
   • The company names its ability to continue or grow buy-sell revenue as a key factor affecting its financial condition, and says that if the orders cease its margin, results and cash flows could be hurt. 68
   Confidence 85 of 100Wrong if A fiscal year in which the LED chip, component and lighting lines alone cover operating expenses, or in which the company reports income from operations with no buy-sell revenue.
