1 serious warning sign in Super Micro Computer’s filings.

We look for five warning signs: doubt it can keep going, weak checks on its own accounts, a notice that its past accounts can't be relied on, a change of auditor, and one customer bringing in a big share of sales. We don't check lawsuits, investigations or debt yet.

We checked the auditor's report, internal controls, restatement notices, auditor changes and big customers in the 10-K filed 31 Aug 2026, and no later 8-Ks.

• Weak checks on its own accounts

  Serious

  The company said its checks on its own accounts did not work at year end. Mistakes could slip into the numbers.

  “Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of June 30, 2026, due to the material weakness in our internal control over financial reporting, described below, that was previously identified in our Annual Report on Form 10-K for the fiscal year ended June 30, 2025, filed on August 28, 2025.”

  (a) Management’s Evaluation of Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, is responsible for evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of June 30, 2026. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that their objectives are met. Because of the inherent limitations in all control systems, no evaluation of disclosure controls and procedures can provide absolute assurance that all disclosure control issues, if any, have been detected. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of June 30, 2026, due to the material weakness in our internal control over financial reporting, described below, that was previously identified in our Annual Report on Form 10-K for the fiscal year ended June 30, 2025, filed on August 28, 2025. Notwithstanding this identified material weakness, management believes and has concluded that the consolidated financial statements included in this Annual Report fairly present, in all material respects, our financial condition, results of operations, and cash flows for the periods presented in conformity with U.S. GAAP.

• Changed auditor

  Worth knowing

  The company changed its auditor (the firm that checks its books) in the last two years.

  “On October 24, 2024, Ernst & Young LLP (“EY”) sent the members of the Audit Committee a letter of resignation as the Company’s registered public accounting firm (the “Resignation Letter”).”

• One big customer

  Worth knowing

  One customer brings in a big share of sales: 28.1% last year. Losing that customer would hurt.

  “For the fiscal year ended June 30, 2026, sales to one customer represented 28.1 % of total net sales.”

• Its accounts show patterns that sometimes come before companies have to correct past results (Beneish score).
• Profits run ahead of cash.

Whether the price already reflects the risks is what the deep dive is for.

• Climate change may have a long-term impact on our business.

  Could happen

  Climate change may have an increasingly adverse impact on our business and on our customers, partners and vendors. Water and energy availability and reliability in the regions where we conduct business is critical, and certain of our facilities may be vulnerable to the impacts of extreme weather events. Extreme heat and wind coupled with dry conditions in Northern California may lead to power safety shut offs due to wildfire risk, which can have adverse implications for our offices and data centers, including impairing the ability of our employees to work effectively. Climate change, its impact on our supply chain and critical infrastructure worldwide and its potential to increase political instability in regions where we, our customers, partners and our vendors do business, may disrupt our business and cause us to experience higher attrition, losses and costs to maintain or resume operations.

• We have been, are currently, and may in the future be subject to various lawsuits and other legal proceedings, disputes, claims, and government inquiries and investigations, which could cause us to incur substantial costs or require us to change our business practices in a way that could seriously harm our business, and any orders, actions or rulings not in our favor could have a material adverse effect on our business, results of operations, and financial condition.

  Could happen

  The Company also received a grand jury subpoena from the U.S. Attorney’s Office for the Southern District of New York seeking documents and information relating to the individuals and facts referenced in the Indictment, as well as the Company’s compliance program and internal controls, and related issues. The Company has also received other subpoenas, and inquiries from the Department of Justice, the Office of Export Enforcement (“OEE”) of BIS, as well as foreign authorities requesting documents and information relating to certain other customers. The Company has not been informed that it is the target of any of these investigations to date, but if we become the target of any of these investigations, the Department of Justice could pursue civil or criminal enforcement actions against us, seek monetary or other penalties from us (including disgorgement), or require changes to our compliance program and internal controls.

• We have been, are currently, and may in the future be subject to various lawsuits and other legal proceedings, disputes, claims, and government inquiries and investigations, which could cause us to incur substantial costs or require us to change our business practices in a way that could seriously harm our business, and any orders, actions or rulings not in our favor could have a material adverse effect on our business, results of operations, and financial condition.

  In connection with the indictment of three former associates, the Company completed an independent investigation, which was jointly led by our Lead Independent Director and the Chair of the Board’s Audit Committee. The independent investigation was conducted by Munger, Tolles & Olson LLP, and it engaged AlixPartners LLP as an independent forensic accounting consultant (collectively, the law firm and the accounting consultant are referred to as the “Independent Advisors”). The results of the investigation were reported to the entire Board. The investigation reviewed the customer transactions that were the subject of the Indictment, as well as transactions with a selection of other customers that purchased restricted products. The investigation did not find any evidence that any current member of senior management had knowledge of the alleged diversion scheme or of any actual diversion of restricted products by the Company. The investigation found no instance in which the Company directly sold export-controlled products to known restricted parties or locations, and found no basis for concluding that the Company’s previously issued financial statements could not be relied upon based on the potential diversion of restricted products. The investigation also concluded that the Company had developed and maintained its export compliance program as its sales of restricted products increased during the period under review, and found that the Company’s compliance personnel acted in good faith, with the support of management, to mitigate the risk of export-controlled products being diverted to restricted parties or locations. In connection with the internal investigation, the Company took personnel actions, including terminations, with respect to its sales, technical support and business development functions staff for violations of various company policies. With the assistance of the Independent Advisors, the independent directors made recommendations to further enhance the Company’s export compliance program, which the Board has adopted in full and is in the process of implementing. Notwithstanding the conclusion of this internal investigation, the government investigations and inquiries described above and below remain ongoing, are not bound by the conclusions of the internal investigation, and could result in enforcement actions, penalties, fines or other adverse consequences to the Company. In addition, although the Company has taken the measures described above and adopted the Independent Advisors' recommendations in full, there can be no assurance that such measures will be effective in preventing similar circumstances from arising in the future or that the Company will not become subject to similar lawsuits, legal proceedings, disputes, claims, government inquiries or investigations.

• We are subject to complex laws, rules, regulations, and political and other actions, including restrictions on the export of our products, which may adversely impact our business.

  Could happen

  For example, we have received multiple subpoenas from the OEE of BIS (the “BIS Inquiries”), including at least two subpoenas and one informal request relating to a certain customer implicated by the facts and circumstances that are also the subject of the Indictment. The BIS Inquiries seek documents relating to our business, customers, products, transactions and export compliance practices. We cannot predict the scope, duration or outcome of the BIS Inquiries, and additional subpoenas, civil investigative demands or other requests may be issued. Although we are fully cooperating with these inquiries, and although we have not been informed that we are the target of any of these inquiries, it is possible that these matters could result in significant penalties, fines or other material consequences, including criminal charges. In connection with the BIS Inquiries, BIS could seek to suspend, revoke or deny our export privileges, including through a temporary or permanent denial order that would restrict or prohibit us from participating in transactions subject to the Export Administration Regulations. Even absent a formal enforcement action, the BIS Inquiries may require substantial legal, consulting and compliance expenditures, divert management attention, impair our relationships with customers, suppliers, channel partners and government counterparties, damage our reputation, and adversely affect our ability to raise capital or complete strategic transactions. Any of these outcomes could materially and adversely affect our business, financial condition, results of operations, cash flows and the trading price of our securities.

• If negative publicity arises with respect to us, our employees, our third-party service providers or our partners, our business and operating results could be adversely affected, regardless of whether the negative publicity is true.

  Already happened

  On March 19, 2026, the U.S. Attorney’s Office for the Southern District of New York unsealed an indictment of three individuals either employed or associated with the Company at the time, including Yih-Shyan (Wally) Liaw, a former Senior Vice President, Business Development and director on our Board, in connection with an alleged conspiracy to commit export control violations (the “Indictment”). Although the Company is not named as a defendant or alleged to be a co-conspirator in the Indictment, and the three individuals are no longer employed or associated with the Company, the Company has been cooperating with the government’s investigation. The Indictment, as well as the prior publication of the Report and our previous Delinquent Reports have all contributed to significant volatility in, and declines of, the trading price of our common stock, as well as harm to our reputation, and could continue to do so in the future.
