Super Micro Computer (Supermicro): control, related parties, accounting and export controls

analysisThe dossier sets out, from SEC filings, court records and official registers, who owns and runs Supermicro and its Taiwanese related-party suppliers, the terms of their dealings, the 2017–2020 accounting investigation and SEC settlement, the 2024 auditor resignation and short-seller allegations with the company's and its Special Committee's answers, the export-control cases from 2006 to 2026 and the shareholder suits, keeping every response and outcome beside the account it concerns. ^{1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24}

analysisSuper Micro Computer, Inc. was incorporated in California in September 1993 and reincorporated in Delaware in March 2007; its principal executive offices are at 980 Rock Avenue, San Jose, California. Its common stock trades on the Nasdaq Global Select Market under the symbol SMCI, and depositary shares for its 7.00% Series A Mandatory Convertible Preferred Stock under SMCIP. The SEC's EDGAR record for Central Index Key 0001375365 classifies it under industry code 3571 (electronic computers) as a large accelerated filer with a fiscal year ending June 30; the same record still gives California as the state of incorporation, a difference from the company's own filings that the records reviewed do not explain. ^{1 2 3}

analysisSales have risen steeply. Revenue grew from $14,989.3 million in fiscal 2024 to $21,972.0 million in fiscal 2025 (46.6%) and to $39,063.1 million in fiscal 2026 (77.8%), which Supermicro attributes mainly to shipments for customers' data-centre deployments, including large design wins from a few customers. Net income was $640.0 million in fiscal 2023, $1,152.7 million in fiscal 2024, $1,048.9 million in fiscal 2025 and $2,230.5 million in fiscal 2026. Full-time employees rose from 5,684 to 6,265 between fiscal 2024 and fiscal 2025. ^{1 2 4}

analysisGrowth tied up cash and concentrated sales. In fiscal 2024 net cash used in operating activities was $3,149.6 million higher than a year earlier, which the company attributes mainly to working capital for customer demand and growth, including increases of $3,000.0 million in inventory and $1,277.3 million in accounts receivable. One unnamed customer accounted for 20% of fiscal 2024 net sales, and at June 30, 2024 a single unnamed customer accounted for 44.8% of accounts receivable. Of fiscal 2024 net sales of $14,989.3 million, $10,187.3 million came from the United States and $2,912.6 million from Asia. ⁴

analysisAt June 30, 2024 about half of Supermicro's 5,684 full-time employees (2,885) worked in research and development and 2,659 were based at the San Jose facilities. At June 30, 2026 it used about 5.7 million square feet of owned and leased space, with manufacturing abroad mainly in Taiwan, Malaysia and the Netherlands. Stockholders' equity rose from $1,972.2 million at June 30, 2023 to $5,417.4 million a year later. The company has never paid a cash dividend on its common stock; a ten-for-one stock split took effect on October 1, 2024, and on August 27, 2026 the board adopted amended bylaws that, among other changes, added exclusive-forum provisions for certain corporate and Securities Act claims. ^{4 1}

analysisCharles Liang founded Supermicro and has been its President, Chief Executive Officer and Chairman since its inception in September 1993; Sara Liu, his wife, co-founded the company and is a Senior Vice President and director. The board says combining the chairman and chief executive roles suits its relatively small size and his experience, and it has a lead independent director. ¹

analysisAt July 31, 2026 Charles Liang and Sara Liu together beneficially owned 81,772,121 shares, or 12.2%, counting options exercisable within 60 days. The other holders above 5% were Jane Street Group (8.6%), BlackRock (6.3%), Capital Ventures International (6.1%), Vanguard Capital Management (5.8%) and Vanguard Portfolio Management (5.0%). On October 14, 2026 the board appointed Mark Long Chief Financial Officer in place of David Weigand. ^{2 3}

analysisSupermicro's annual reports describe Ablecom Technology Inc. and Compuware Technology Inc. as privately held Taiwan-based related parties whose sales to Supermicro make up a substantial majority of their net sales; the fiscal 2019 report instead describes most of Compuware's sales as resales of Supermicro products to others. Purchases from the two equalled 8.3%, 6.6% and 4.3% of Supermicro's cost of sales in fiscal 2022, 2023 and 2024. ^{1 2}

analysisSteve Liang, Charles Liang's brother, is Ablecom's chief executive; he and his family owned about 35% of Ablecom at June 30 of 2024, 2025 and 2026, while Charles Liang and Sara Liu together owned about 10.5%. Bill Liang owned about 1.8% of Ablecom and sat on its board in 2025. Bill Liang, a brother of both Charles and Steve Liang, is Compuware's chief executive; at June 30, 2025 he and his family owned about 16% of Compuware and Ablecom about 15%. Charles Liang and Sara Liu held no Compuware stock, and Supermicro owns no shares in either company. ^{3 1 4 5 6}

analysisSupermicro's fiscal 2017 annual report, filed only in May 2019, corrected earlier years for errors and irregularities mainly in the timing of revenue and expense recognition; product revenue for fiscal 2015 and 2016 had been recognised prematurely, which the restatement note attributed in part to "an aggressive focus on quarterly revenue without sufficient focus on compliance". Because it had not filed its periodic reports or held an annual meeting, its stock was suspended from Nasdaq on August 23, 2018 and delisted on March 22, 2019; it was relisted on January 14, 2020. ^{1 2 3}

analysisOn August 25, 2020 the SEC instituted and settled cease-and-desist proceedings finding that Supermicro had engaged in improper accounting, recognising revenue prematurely and understating expenses from at least fiscal 2015 through fiscal 2017. The company consented without admitting or denying the findings, except as to the Commission's jurisdiction, and the order states that its findings were made under the company's offer of settlement and are not binding on any other person or entity. ⁴

analysisOn August 27, 2024 the short seller Hindenburg Research, which disclosed a short position, published a report alleging accounting manipulation, self-dealing with the CEO's siblings and sanctions evasion; Supermicro said the report contained false or inaccurate statements. A Special Committee of the board later reported no evidence of attempts to circumvent export controls and found that the related parties named had been disclosed as required, did not need to be disclosed or, in one case, had become a related party during fiscal 2024; the SEC subpoena Supermicro received on November 19, 2024 sought documents that overlap with the report's allegations. The report states the opinions of a short seller that gains if the share price falls and rests largely on unnamed former employees and trade data not among the records reviewed, so its assertions are treated here only as allegations. ^{5 6 7 8}

analysisOn October 24, 2024 Ernst & Young (EY) resigned as auditor during its first audit, of fiscal 2024, writing that it could no longer rely on management's and the Audit Committee's representations. Supermicro disagreed, and the board's Special Committee reported on December 2, 2024 that EY's conclusions were not supported by the facts it examined; these are the conclusions of a committee of Supermicro's own board. BDO USA, appointed on November 18, 2024, gave unqualified opinions on the financial statements but adverse opinions on internal control; at June 30, 2026 one material weakness, in information technology general controls, remained unremediated. ^{9 5 10 8 7}

analysisIn 2006 Supermicro pleaded guilty to illegally exporting to Iran motherboards controlled for national security reasons; it paid a $150,000 criminal fine and agreed to a $125,400 administrative settlement. The company said the violations dated from 2001 to 2003 and that after receiving subpoenas in 2004 it ended its relationship with the distributor concerned and set up a new export compliance program. ^{1 2}

analysisOn March 19, 2026 federal prosecutors in the Southern District of New York unsealed an indictment charging Yih-Shyan "Wally" Liaw, Ruei-Tsang "Steven" Chang and Ting-Wei "Willy" Sun with conspiring to divert to China servers assembled in the United States with U.S. artificial-intelligence technology. The charging papers do not name the manufacturer; Supermicro's annual report describes the three as "either employed or associated with the Company at the time", and the company is not charged. Liaw and Sun pleaded not guilty in April 2026; Sun pleaded guilty on October 8, 2026, Liaw's trial is set for March 29, 2027, and Chang has not appeared. An indictment is an accusation, not a finding. ^{3 4 5}

analysisAccording to Supermicro, an independent investigation led by two of its directors found no evidence that any current member of senior management knew of the alleged scheme and no basis to consider earlier financial statements unreliable; the report itself is not public. In August 2026 prosecutors in Keelung, Taiwan, indicted nine people after an investigation into unlawful exports of AI servers, including two senior sales directors of the Taiwan subsidiary of a U.S. server maker whose masked description matches Supermicro; neither Supermicro nor its subsidiary is a defendant, and Supermicro said the authorities had confirmed it was not a target. ^{5 6 7}

analysisShareholders have brought securities class actions against Supermicro, Charles Liang and David Weigand. On September 30, 2026 the court dismissed the consolidated 2024 class action with leave to amend, a ruling on the sufficiency of the pleadings rather than the merits. A second set of class actions filed from March 2026 was consolidated in July 2026 and an amended complaint followed on October 9, 2026, with no ruling on the merits by the cutoff; Supermicro called the matters too preliminary to assess. The 2026 complaints are plaintiffs' allegations that no court has found true. ^{1 2 3 4}

analysisA screening query against consolidated sanctions, politically exposed person and watch-list data on October 17, 2026 returned no sanctions or politically exposed person entry for Supermicro; its single candidate was a watch-list record derived from SEC enforcement information on matters with harmed investors, listing no sanctions programme and carrying no case number or event date. ¹

analysisOn the cover of its fiscal 2024 annual report Supermicro answered "No" to whether it had filed all reports required in the preceding 12 months. Neither that cover nor the fiscal 2026 cover indicates that the financial statements correct an error in previously issued statements. ^{2 3}
