SemiLEDs Corp, the LED chip maker whose website showcases RoHS-compliant products and a governance page heavy enough to anchor a small yacht, has just filed its third-quarter “preliminary” results for the period ending 31 May 2026. The headline figure is revenue of $9.1 million, a sharp drop from the $43.0 million posted in the prior annual filing, but the real story is in the composition: 68% of the nine-month revenue came from buy-sell purchase orders of equipment, and 99% of total net revenues for both the three and nine months ended May 31, 2026 flowed from the top ten customers. That is not diversification; that is a revenue monoculture.

The company’s product pages promise a “strong value proposition” in LED chips, with infrastructure and processes “designed to minimise the impact on the environment” and compliance with RoHS. The marketing copy is polished, but the balance sheet tells a different story: $6.0 million in cash, $4.7 million in inventory, and an operating income of $1.4 million in the quarter against liabilities of $14.5 million. The LEDs may be green, but the cash cycle is feeling the heat. Stockholders’ equity stands at $3.1 million, a figure that invites questions about sustainability when 99% of revenue rides on ten customers and 68% of revenue is tied to equipment resale orders rather than chip sales.

SemiLEDs’ board, meanwhile, has charters for audit, compensation, and nominating/governance committees, each posted on the company’s website under “Corporate Governance.” The charters are real, the board oversight is real, and the shareholder approvals for equity plans are real-amendments in 2014 and 2019 increased authorised shares by 750,000. What is less clear is whether any of this governance machinery is materially altering the company’s customer concentration or cash dynamics. The board charters do not change the fact that the company’s revenue is overwhelmingly concentrated, its cash balance is modest, and its inventory is growing. The company’s press release announcing “preliminary” third-quarter results for fiscal 2026 arrived on 14 July 2026, but “preliminary” is not “final,” and the final numbers remain outstanding.

For those watching the stock, the SEC filings are the primary source, with the company’s own product and news pages offering colour rather than data. The latest 10-Q, filed on 14 July 2026, provides the core financials for the quarter ended 31 May 2026, while the DEF 14A and 8-K/A shed light on governance and announcements, respectively. The company’s product pages and news rail confirm partnerships like the industrialisation agreement with CrayoNano for nanowire UV-C LED chips, but these developments do not yet translate into diversified revenue or reduced customer concentration. The filing index on SEC EDGAR and the companyfacts JSON provide the raw data, but the human story is in the gap between the polished platform and the balance sheet reality.
