- Documented: EDGAR's list of persons reporting ownership of Supermicro shares records these officer capacities: Jin Xiao, Sr. Corporate VP, Engineering; Kenneth Cheung, SVP, Chief Accounting Officer; Vikranth Malyala, SVP, Chief Business Officer; Matthew Thauberger, Chief Revenue Officer (listed as “other”); David Weigand, SVP, Chief Compliance Officer; and Don Clegg, SVP, Worldwide Sales. [src-022]
- Documented: The same EDGAR list of Supermicro reporting persons also records former insiders in their reported capacities: Alex Hsu as Chief Sales & Marketing Officer, Phidias Chou as VP Worldwide Sales, Howard Hideshima as an officer, and Yih-Shyan (Wally) Liaw as director and Secretary & VP of International Sales. [src-022]
- Documented: The EDGAR owner pages of David Weigand, Don Clegg, George Kao, Jin Xiao, Vikranth Malyala, Matthew Thauberger, Alex Hsu, Howard Hideshima and Phidias Chou each show Super Micro Computer, Inc. as the issuer of the reported holdings and Supermicro's 980 Rock Avenue, San Jose office as the mailing address. Hideshima's page records his capacity as Chief Financial Officer and Kao's as SVP, Operations. [src-047] [src-093] [src-078] [src-094] [src-051] [src-117] [src-116] [src-063] [src-092]
- Documented: Howard Hideshima's EDGAR owner page shows his last reported Supermicro transaction on November 22, 2017. Phidias Chou's page shows his last reported transactions on November 10, 2017, when 338 restricted stock units converted into shares and 128 shares were withheld, leaving 1,560 shares held directly. [src-063] [src-092]
- Documented: Supermicro's Chinese-language leadership page states that Alex Hsu is its senior chief executive for strategic business and has held senior positions since October 2003: president of the European office and vice president of operations (2003–2004), senior vice president of sales (2004–2006), chief sales and marketing officer (July 2006 to August 2009), senior chief executive for strategic business and executive director of Supermicro Technology (Beijing) Co., Ltd. from August 2009, and chief operating officer from 2019 to 2021. It states that he has been chairman of Supermicro Taiwan since February 2018 and was earlier president and chief operating officer of Bizlink and of Oplink Communications, Inc. [src-112]
- Documented: Alex Hsu's EDGAR owner page shows an initial Form 3 dated March 28, 2007 reporting 120,000 Supermicro shares held indirectly, and a second Form 3 dated September 12, 2019 reporting 606 shares held directly; on March 27, 2020 he was awarded options over 38,000 shares and 30,000 restricted stock units. [src-116]
- Documented: A Chinese-language notice of Asia University dated April 10, 2024, describing a visit by the university's delegation to Supermicro's headquarters in March 2024, names Supermicro's Alex Hsu as 許春來, with the title senior chief executive for corporate strategy (資深首席企業策略執行). [src-111]
- Unresolved: Two notices by Asia University about the same March 2024 visit by its delegation to Supermicro's headquarters describe Phidias Chou differently: the English notice of April 15, 2024 says the delegation met Charles Liang and “consultants Alex Hsu and Phidias Chou”, while the Chinese notice of April 10, 2024 calls Chou a senior vice president (資深副總裁) and Hsu a senior chief executive for corporate strategy. [src-084] [src-111] [src-006]
  - Qualification: Both accounts come from the visiting university, not from Supermicro. Supermicro's own leadership page describes Alex Hsu as a current senior executive rather than a consultant, so the English notice's label is not reliable for him; no Supermicro record reviewed states Chou's capacity in 2024. His last recorded Supermicro office was Senior Vice President, Worldwide Sales, which he resigned effective January 30, 2018.
- Documented: Silvaco, Inc. announced on February 20, 2020 that it had appointed Howard Hideshima as Chief Financial Officer. The announcement described him as Supermicro's former Senior Vice President and Chief Financial Officer, who had led its 2007 initial public offering, and listed earlier senior roles at Force10 Networks, Virtual Silicon Technology, Internet Corporation and ESS Technology. [src-108]
- Documented: On August 25, 2020 the SEC also instituted and simultaneously settled separate cease-and-desist proceedings against Howard Hideshima, Supermicro's former Chief Financial Officer (Administrative Proceeding File No. 3-19928, Release No. 34-89657). In its orders the Commission found that the respondents violated the federal securities laws through the improper accounting of fiscal 2015 to 2017, and that Hideshima signed and/or approved the misstated reports. He was ordered to pay disgorgement of $260,844.00, prejudgment interest of $40,212.00 and a civil money penalty of $50,000.00. [src-055]
  - Qualification: The records reviewed include the SEC's Fair Fund page describing the Hideshima order, not the order itself; whether he admitted or denied the findings is not stated in the retained record.

The board determined that four of the seven were independent under Nasdaq listing standards: Tuan, Hayes, Hinckley and Tsai. [src-020]
- Documented: In the same proxy statement the three standing committees consisted only of independent directors: the Audit Committee was chaired by Edward J.

It explained that no annual meeting for the election of directors had been held since the meeting following fiscal 2016. [src-019]
- Documented: The proxy statement for Supermicro's annual meeting of May 19, 2023 reported eight authorized and eight serving directors: Charles Liang, Sherman Tuan, Tally Liu, Robert Blair, Judy Lin, Sara Liu, Daniel Fairfax and Shiu Leung (Fred) Chan.

- Documented: Supermicro's proxy statement of March 2026 reported nine directors, of whom the board had determined six to be independent under SEC rules and Nasdaq listing requirements: Judy Lin, Robert Blair, Scott Angel, Sherman Tuan, Susan Mogensen (Susie Giordano) and Tally Liu.

[src-001]
- Documented: Supermicro's annual report for fiscal 2026 states that, as of its filing in August 2026, the board had eight authorized and eight serving directors, six of them independent: Judy Lin, Robert Blair, Scott Angel, Sherman Tuan, Susan Mogensen (Susie Giordano) and Tally Liu; the others were Charles Liang and Sara Liu.

- Documented: During fiscal 2024 Supermicro adopted a new compensation clawback policy, effective October 25, 2023, which it describes as complying with new Nasdaq rules and SEC requirements. [src-001]
- Documented: On May 3, 2024 Nasdaq notified Supermicro that it did not comply with Listing Rule 5605(c)(2)(A), which requires an audit committee of three independent directors, after Shiu Leung (Fred) Chan resigned from the board and the Audit Committee. On May 9, 2024, within the cure period, the company added Robert Blair and Judy Lin to the Audit Committee, which then consisted of Tally Liu, Dan Fairfax, Robert Blair and Judy Lin. [src-043]
- Unresolved: Supermicro's filings give two different start dates for Sara Liu's board service. A 2007 registration statement, the proxy statements of 2011, 2023 and 2026 and the annual reports for fiscal 2023 through fiscal 2026 say she has been a director since the company's inception in September 1993; the annual reports for fiscal 2017 (filed in 2019), 2019, 2020 and 2021 and the 2020 proxy statement say she has been a director since March 2007. [src-001] [src-020] [src-045] [src-002] [src-016] [src-019] [src-014] [src-012] [src-121] [src-044] [src-062] [src-061] [src-119]
  - Qualification: The filings do not reconcile the two dates, and this publication does not choose between the two accounts.
  - Response: The 2011 and 2020 proxy statements note generally that listed dates include service as directors of predecessor companies; neither says which date applies to Sara Liu.
  - Outcome: The filings reviewed from 2023 to 2026 all use the September 1993 date; none of them explains the change from March 2007.
- Documented: Yih-Shyan (Wally) Liaw, a Supermicro co-founder, was described in the 2011 proxy statement as Vice President of International Sales, Corporate Secretary and a director since the company's inception in September 1993; from 1988 to 1991 he had been Vice President of Engineering at Great Tek, a computer company. He resigned from the board in January 2018, was reappointed in December 2023 and resigned again effective March 20, 2026. [src-020] [src-006] [src-001] [src-002]

Total related-party cost of sales was $650,658 in fiscal 2025 and $725,694 in fiscal 2026. [src-002]
- Documented: Supermicro's accounts payable to Ablecom were $55,460 thousand at June 30, 2025 and $64,313 thousand at June 30, 2026, and its accounts payable to Compuware were $74,292 thousand and $52,749 thousand at the same dates. [src-002]
- Documented: Supermicro's outstanding purchase orders to Ablecom were $39.5 million cancelable and $36.0 million non-cancelable at June 30, 2022, $37.4 million and $23.7 million at June 30, 2023, and $99.0 million and $58.8 million at June 30, 2024; non-cancelable orders were $30.6 million at June 30, 2025 and $59.8 million at June 30, 2026. Supermicro describes the non-cancelable orders as its maximum exposure to loss from Ablecom and states that it does not guarantee any obligations of Ablecom or losses of its equity holders. [src-045] [src-012] [src-002]
- Documented: Ablecom manufactured about 91.8%, 88.2% and 91.9% of the chassis included in the products Supermicro sold in fiscal 2021, 2022 and 2023, and about 93.6%, 95.4% and 95.3% of the chassis Supermicro purchased in fiscal 2024, 2025 and 2026. The annual report for fiscal 2026 states that Ablecom makes substantially all the chassis in Supermicro's products and that Supermicro's business could suffer if Ablecom suddenly became unable to supply them and substitute suppliers could not be qualified quickly. [src-045] [src-002]
  - Qualification: The earlier percentages measure chassis in products sold and the later ones chassis purchased; the two series are not on the same basis.
- Documented: Under its agreements with Ablecom, Supermicro outsources part of its design work and a significant part of its server-chassis manufacturing. Supermicro pays Ablecom for design, engineering and tooling and keeps the intellectual property; Ablecom buys most materials from third parties, while components that Supermicro supplies, such as power supplies, are sold back to Supermicro at the price at which Supermicro sold them, so these component transactions produce no revenue for Supermicro. The agreements include product development, production and service agreements, credit agreements, product manufacturing and manufacturing services agreements and warehouse leases. [src-012] [src-002]
- Documented: Supermicro filed with the SEC in 2007, as Exhibit 10.24, a Product Manufacturing Agreement with Ablecom Technology Inc. dated January 8, 2007. Ablecom agreed to manufacture products under Supermicro's purchase orders for an initial one-year term that renews automatically for one-year periods unless Supermicro gives three months' or Ablecom six months' notice of non-renewal. During the term Supermicro agreed not to contract any third party to manufacture the products, a restriction that lapses if Ablecom is unable or unwilling to manufacture, raises its fees by more than an agreed annual percentage, or misses the agreed delivery schedule. [src-060]
- Documented: The 2007 Product Manufacturing Agreement was signed for Ablecom by Steve Liang as President on December 29, 2006 and for Supermicro by its CFO Howard Hideshima on January 8, 2007. It gives Ablecom's principal place of business as 5th Floor, No. 228, Lian-Cheng Rd., Chung-Ho City, Taipei County, Taiwan. [src-060]
- Documented: Supermicro's annual report for fiscal 2024 states that, under its agreements with Ablecom and subject to certain exceptions, Ablecom has the exclusive right to be Supermicro's supplier of the specific products developed under those agreements. [src-012]
- Documented: Before its 2007 initial public offering Supermicro also sold server products to Ablecom under a distribution agreement for Taiwan, with net sales to Ablecom of about $3.9 million in fiscal 2006 and $1.8 million in the three months ended September 30, 2006, on terms the company called comparable to those of similar third-party distributors. Its Taiwan subsidiary leased about 14,000 square feet of office and factory space from Ablecom for about $13,000 a month under a one-year lease expiring in February 2007, and from October 2004 to February 2006 leased about 8,400 square feet from Ablecom for about $6,200 a month. [src-119]
- Documented: Supermicro's annual report for fiscal 2026 states that it expects Ablecom and/or Compuware to continue warehousing an increasing number of components and subassemblies made by multiple suppliers before shipment to Supermicro's facilities in the United States and Europe, that it expects to continue leasing office space from them in Taiwan for research and development, and that it operates a joint management company with Ablecom for the common areas of their separately built manufacturing facilities in Taiwan. [src-002]
- Documented: On November 8, 2021 Supermicro's wholly owned Taiwan subsidiary signed a Tripartite Agreement with Ablecom and Compuware for a three-way purchase of land near Supermicro's campus in Bade, Taiwan. Ablecom later advised that its agreements to buy the land from the third-party owners had been terminated, and the Tripartite Agreement was terminated in the quarter ended December 31, 2022. [src-014]
- Documented: During fiscal 2026 Supermicro entered into a 50-year superficies (land-use right) agreement with Ablecom covering three parcels of land in Taoyuan, Taiwan, which produces recurring lease income for Supermicro with rent adjusted periodically to the Taoyuan announced land value index; the rental income recognised in fiscal 2026 was not material. [src-002]
- Documented: In the fourth quarter of fiscal 2026 Supermicro arranged for Ablecom to resell certain Supermicro products to an end customer in Japan. Supermicro states that the transaction was in the ordinary course of business and on terms consistent with those negotiated with other third-party resellers for similar transactions. [src-002]
- Documented: Supermicro's annual report for fiscal 2026 states that Supermicro has extended a $10.0 million trade credit line to Ablecom with net 30-day payment terms under a credit agreement. [src-002]

Payments to Compuware for design services, tooling assets and miscellaneous costs were $1.2 million and $0.7 million, and outstanding purchase orders to Compuware were $111.7 million and $70.6 million. [src-044]
- Documented: Supermicro bought products from Compuware worth $130.6 million in fiscal 2020, $113.4 million in fiscal 2021 and $170.3 million in fiscal 2022, and owed Compuware $46.5 million, $46.4 million and $60.0 million at the end of those years. [src-014]
- Documented: Supermicro sold products to Compuware worth $36.3 million in fiscal 2023, $46.6 million in fiscal 2024, $30.2 million in fiscal 2025 and $20.0 million in fiscal 2026, and bought products from Compuware worth $217.0 million, $280.8 million, $328.3 million and $335.2 million. Compuware owed Supermicro $24.9 million, $10.0 million, $13.0 million and $0.6 million at the end of those years; Supermicro owed Compuware $53.4 million, $66.4 million, $74.3 million and $52.7 million. [src-001] [src-002]
- Documented: Supermicro's outstanding purchase orders to Compuware were $156.2 million cancelable and $46.8 million non-cancelable at June 30, 2023 and $129.7 million and $93.5 million at June 30, 2024; non-cancelable orders were $118.3 million at June 30, 2025 and $182.2 million at June 30, 2026. Supermicro describes these orders as its exposure to loss from Compuware and states that it does not guarantee any obligations of Compuware or losses of its equity holders. [src-012] [src-002]
- Documented: Compuware manufactured about 96.6%, 94.6% and 94.4% of the power supplies Supermicro purchased in fiscal 2024, 2025 and 2026. [src-002]
- Documented: Supermicro outsources to Compuware part of its design work and a significant part of its power-supply manufacturing; it pays Compuware for design, engineering and tooling and keeps the intellectual property. Compuware also makes motherboards, backplanes and other circuit-board components from components Supermicro sells to it, and sells the finished products back at the price of those components plus a “manufacturing value added” fee and other charges, which the two companies frequently renegotiate; Supermicro recognises no revenue on these component sales. [src-012]
- Documented: Supermicro's agreements with Compuware include product development, production and service agreements, product manufacturing agreements and office leases. Its annual report for fiscal 2024 describes a $65.0 million trade credit line extended to Compuware with net 60-day terms; on November 19, 2025 Supermicro extended a $200.0 million trade credit line to Compuware with net 90-day terms. [src-002] [src-012]
- Documented: Supermicro appointed Compuware as a non-exclusive distributor of its products, in Taiwan, China and Australia according to its annual reports for fiscal 2017, 2023 and 2024, and in Taiwan, China, Australia, Malaysia and the United States according to its annual report for fiscal 2026. Compuware buys at a discount from Supermicro's standard volume price and in exchange installs the products at end-customer sites and provides first-level customer support. Supermicro states that it believes the distribution terms are similar to those of comparable third-party distributors. [src-045] [src-002] [src-001] [src-012] [src-016]
- Documented: Supermicro agreed to pay Compuware a finder's fee of about $1.6 million in fiscal 2025, equal to 1% of net sales to a customer Compuware had referred, and about $1.8 million in fiscal 2026, a weighted average of about 0.16% of net sales to a referred customer. Supermicro states that Compuware from time to time acts as its sales representative for a percentage fee comparable to that offered to other sales representatives in the region, and that the finder's fee is consistent with market terms given Compuware's limited role and industry margins. [src-002]
- Documented: In its annual report for fiscal 2024 Supermicro concluded that Ablecom and its affiliate Compuware are variable interest entities, but that Supermicro is not their primary beneficiary because it lacks power over their most significant activities, so it does not consolidate them. [src-012]
- Documented: Supermicro's annual report for fiscal 2023 warns that the company may be disadvantaged by the economic interests of Charles Liang and Sara Liu as Ablecom stockholders and by Charles Liang's personal relationship with the chief executives of Ablecom and Compuware, and that it may not negotiate or enforce contractual terms with Ablecom or Compuware as aggressively as with an unrelated party. [src-045]
- Documented: In its 2007 initial public offering prospectus Supermicro stated that its transactions with Ablecom had historically not been approved by an independent committee of its board of directors because it had no independent directors. [src-119]
- Documented: Supermicro's income statements show sales to all related parties of $47,684 thousand, $29,110 thousand and $33,821 thousand in fiscal 2015, 2016 and 2017, and $79,018 thousand, $147,091 thousand, $60,537 thousand and $69,791 thousand in fiscal 2021 to 2024, and related-party purchases included in cost of sales of $227,661 thousand, $242,638 thousand and $236,062 thousand in fiscal 2015 to 2017 and $239,558 thousand, $371,076 thousand, $384,762 thousand and $552,136 thousand in fiscal 2021 to 2024. [src-016] [src-045] [src-012]
  - Qualification: These totals cover all related parties, not only Ablecom and Compuware.
- Documented: Supermicro's balance sheet shows accounts payable to related parties of $89,134 thousand at June 30, 2023 and $165,295 thousand at June 30, 2024; its cash-flow statements show payments to related parties for property, plant and equipment of $4,818 thousand, $7,844 thousand and $10,625 thousand in fiscal 2022, 2023 and 2024. At June 30, 2026, $0.2 billion of its $34.2 billion of non-cancelable purchase commitments was owed to related parties. [src-012] [src-002]
  - Qualification: These amounts cover all related parties, not only Ablecom and Compuware.
- Documented: Supermicro's purchases are concentrated in a few unnamed suppliers: one supplier accounted for 31.0%, 26.0% and 21.8% of raw-material purchases in fiscal 2017, 2018 and 2019; two suppliers accounted for 11.4% and 18.1% of total purchases in fiscal 2022, 30.7% and 13.5% in fiscal 2023 and 65.4% and 6.3% in fiscal 2024; and one supplier accounted for 65.4%, 64.4% and 63.1% of total purchases in fiscal 2024, 2025 and 2026. [src-044] [src-012] [src-002]
  - Qualification: The filings do not name these suppliers.
- Attributed: The report described Supermicro's dealings with Ablecom and Compuware, which it called controlled by CEO Charles Liang's brothers, as oddly circular: Supermicro provides components that the two companies assemble and sell back to it, they rent warehousing and factory space to it, together they had been paid $983 million over three years, and trade records showed about 99.8% of Ablecom's and 99.7% of Compuware's exports to the United States since 2020 going to Supermicro. [src-081] [src-012] [src-042]
  - Qualification: A short-seller characterization; the payment total and export shares come from the report's own reading of trade records that are not part of the records reviewed here. Supermicro's filings themselves disclose both companies as related parties, the component, warehousing and lease arrangements, the purchase amounts and that sales to Supermicro make up a substantial majority of each company's net sales.
  - Response: Supermicro's Special Committee concluded in December 2024 that the related parties identified in the report had been fully disclosed as required, were not required to be disclosed or, in one case, had become a related party during fiscal 2024 and would be disclosed in the next annual report.

## Who owns and runs Ablecom and Compuware

- Documented: Supermicro's 2007 initial public offering registration statement states that Steve Liang, Ablecom's chief executive and Charles Liang's brother, was a member of Supermicro's board of directors until December 31, 2005 and beneficially owned about 4.5% of Supermicro's common stock before the offering. [src-119]
- Documented: The same registration statement states that at September 30, 2006 Charles Liang and Chiu-Chu (Sara) Liu Liang jointly owned about 30.7% of Ablecom's common stock, Yih-Shyan (Wally) Liaw and his wife about 5.2%, and that Charles Liang, Sara Liu, Wally Liaw, Steve Liang and their relatives together owned over 80% of Ablecom. Charles Liang served as a director of Ablecom during Supermicro's fiscal 2006 but no longer did so. [src-119]
- Documented: Supermicro's annual report for fiscal 2017 (the year ended June 30, 2017) states that Steve Liang and other Liang family members, including other brothers of Charles Liang, owned about 36.0% of Ablecom at June 30, 2016 and 2017; that Charles Liang and Sara Liu together owned about 10.5%; that certain family members of Wally Liaw, then Senior Vice President of International Sales and a director, owned about 11.7% at June 30, 2017; and that Supermicro does not and never did own any Ablecom stock. Charles Liang was an Ablecom director only during fiscal 2006, and Bill Liang sat on Ablecom's board. [src-016]
- Unresolved: Supermicro's filings disagree on who held about 0.4% of its common stock at June 30, 2017. The annual report for fiscal 2017 says in its risk factors and in the related-party note that Ablecom owned about 0.4%, but in its related-transactions section that Ablecom's chief executive Steve Liang owned about 0.4%; the amended quarterly report for the quarter ended March 31, 2017 likewise says Ablecom owned about 0.4% at that date. The 2020 proxy statement and the annual report for fiscal 2019 attribute the 0.4% to Steve Liang and state that he owned no shares from June 30, 2018; each annual report reviewed from fiscal 2020 to fiscal 2026 states that he owned no shares at the three most recent fiscal year-ends. [src-016] [src-019] [src-012] [src-044] [src-046] [src-062] [src-002]
  - Qualification: The records do not resolve whether the 0.4% holding at June 30, 2017 belonged to Ablecom or to Steve Liang personally.
  - Outcome: None of the later filings reviewed corrects or explains the fiscal 2017 report's statements that Ablecom held the 0.4%.
- Documented: Supermicro's 2020 proxy statement and annual report for fiscal 2019 state that throughout fiscal 2018 and 2019 Charles Liang and Sara Liu together owned about 10.5% of Ablecom, Steve Liang and his family members about 28.8%, and certain family members of Wally Liaw, who until January 2018 was Senior Vice President of International Sales and a director, about 11.7%; Bill Liang was a member of Ablecom's board. [src-019] [src-044]
- Documented: Supermicro's filings state that Steve Liang and his family members owned about 28.8% of Ablecom and Charles Liang and Sara Liu together about 10.5% at June 30, 2022 and again at June 30, 2023. [src-014] [src-045]
- Documented: Supermicro's filings state that Steve Liang and his family members owned about 35.0% of Ablecom at June 30, 2024 and June 30, 2025 and about 35.5% at June 30, 2026, while Charles Liang and Sara Liu together owned about 10.5% at June 30, 2024, 2025 and 2026. At June 30, 2025 Bill Liang owned about 1.8% of Ablecom and sat on its board. [src-012] [src-001] [src-002]
- Documented: Supermicro's filings report a stake in Ablecom held by relatives of Wally Liaw: “certain family members” owned about 11.7% according to the filings for fiscal 2017 to 2019, and “a sibling” owned about 11.7% of Ablecom and 8.7% of Compuware according to the filings for fiscal 2024 to 2026. The annual report for fiscal 2026 adds that Liaw was no longer an employee or director of Supermicro at June 30, 2026. [src-002] [src-012] [src-001]
  - Qualification: The filings do not name the sibling or the family members, and no record reviewed identifies them.
- Documented: Supermicro's March 2026 proxy statement states that at June 30, 2025 Bill Liang and his family members owned about 16.0% of Compuware and Ablecom about 15.0%, and that neither Charles Liang nor Sara Liu owned any Compuware stock; the annual report for fiscal 2026 repeats these percentages without a separate date and adds that Supermicro owns no Ablecom or Compuware stock. [src-001] [src-002]
- Documented: Supermicro's filings describe Bill Liang, a brother of both Charles Liang and Steve Liang, as chief executive of Compuware, a member (later Chairman) of its board, a holder of a significant equity interest in Compuware and a member of Ablecom's board, and Steve Liang as a member of Compuware's board and an equity holder of Compuware. [src-016] [src-045] [src-002]
- Documented: Supermicro's filings describe Steve Liang, Charles Liang's brother, as Ablecom's chief executive and largest shareholder; the annual report for fiscal 2024 states that he owned no Supermicro shares at June 30, 2022, 2023 or 2024. [src-001] [src-012]
- Documented: Supermicro's 2023 proxy statement explains that Ablecom's ownership of Compuware is below 50% but that Compuware remains a related party because Ablecom still has significant influence over its operations. [src-014]
- Documented: Taiwan's company register lists Ablecom Technology Inc. (大訊科技股份有限公司) under unified business number 97489483 with the status 核准設立 (approved and existing) and overseas Chinese or foreign investment (僑外資), incorporated on April 29, 1997 (086年04月29日).

- Documented: For the board term registered as 115年06月03日 to 118年06月02日 (June 3, 2026 to June 2, 2029), the registry lists Steve Liang (梁見發) as Leadtek's chairman representing Ablecom, which holds 18,156,081 shares, Bill Liang (梁見達) as a director representing Compuware, which holds 9,077,496 shares, Chien-Tsun Chang (張建存) as an individual director holding no shares, and four independent directors; 梁傳杰 is registered as manager from 113年12月03日 (December 3, 2024).

The notice published on Taiwan's Market Observation Post System names Ablecom (大訊科技), described as a major shareholder and director of Leadtek, as a possible insider subscriber. [src-064]
- Documented: Supermicro's fiscal 2024 annual report discloses that during fiscal 2024 it sold approximately $0.1 million of products indirectly, through a systems integrator, to Aeon Lighting Technology Inc., a Taiwan company owned more than 10% by James Liang, a brother of CEO Charles Liang, who is also Aeon Lighting's director and CEO.

For the board term 111年06月16日 to 114年06月15日 it registers 梁見國 as chairman holding 8,256,000 shares and one supervisor holding 179,000 shares. [src-057]
- Attributed: A Taiwanese business weekly reported on February 27, 2024 that Charles Liang's fourth brother 梁見國 runs 浩然科技 (Aeon Lighting) independently; that its high-end LED lighting business was at first little connected with Supermicro, but that as the LED market weakened it turned into a supplier making chassis samples for 大訊 (Ablecom) and so became part of Supermicro's supply chain. [src-058]
  - Qualification: A magazine account; Supermicro's filings do not describe Aeon Lighting as a supplier to Ablecom or to Supermicro.
- Documented: Supermicro reports that it and Ablecom jointly established Super Micro Asia Science and Technology Park, Inc. (the "Management Company") in Taiwan to manage the common areas they share for their separately constructed manufacturing facilities. In fiscal 2012 each party contributed $0.2 million for a 50% ownership interest, and certain affiliates of Ablecom serve as the Management Company's directors. [src-002]
- Documented: In its fiscal 2024 annual report Supermicro concluded that the Management Company is a variable interest entity of which Supermicro is the primary beneficiary, because it has the power to direct the activities most significant to it; the Management Company's accounts were consolidated for fiscal 2022 to 2024, with a noncontrolling interest recorded for Ablecom's share.

Its registered businesses are parking-lot operation, management consulting, building cleaning and waste clearance; its representative is 梁見發 (Steve Liang). [src-018]
- Documented: For the board term registered as 113年05月16日 to 116年05月15日 (May 16, 2024 to May 15, 2027), the registry shows Super Micro Management Consulting Inc. owned in equal 500,000-share halves by Ablecom (大訊科技) and Super Micro Computer, Inc. Taiwan (美超微電腦). Steve Liang (梁見發) is chairman and one other director represents Ablecom; three directors represent Supermicro Taiwan; Chien-Tsun Chang (張建存) is supervisor without shares. Steve Liang is also the only registered manager, from 101年04月26日 (April 26, 2012). [src-018]
- Documented: The registry's change history for 53842945 contains nine entries from 101年05月04日 (May 4, 2012) to 114年05月16日 (May 16, 2025), each under the name 美超微管理顧問股份有限公司 with capital of NT$10,000,000 and the same street address; only the administrative name of the district changed after the first entry. [src-018]
- Unresolved: The records do not settle whether Super Micro Asia Science and Technology Park, Inc. and Super Micro Management Consulting Inc. are one company. Supermicro's subsidiary list as of January 31, 2025 names the former as a Taiwan subsidiary; the list as of June 30, 2026, filed with the annual report for fiscal 2026, names the latter instead, although that annual report's own text still names Super Micro Asia Science and Technology Park, Inc. as the consolidated variable interest entity and as the management company established with Ablecom; the December 2025 credit agreement lists the two as separate 50% holdings of Supermicro's Taiwan subsidiary. [src-013] [src-105] [src-059] [src-002]
  - Qualification: Taiwan's registry entry for Super Micro Management Consulting Inc. (53842945) shows that name in every recorded change since 2012 and no earlier English or Chinese name; the records reviewed contain no registry entry under the Asia Science and Technology Park name. The joint management company described in the 10-K may therefore be either company.
- Attributed: A Taiwanese financial daily reported on August 26, 2026 that Ablecom announced its participation in a cash private placement by 州巧科技 (Taiwan securities code 3543) and its acquisition of 州巧's largest shareholding, with the two planning cooperation on AI server racks and liquid cooling. Ablecom chairman Steve Liang (梁見發) was quoted as saying the stake would give Ablecom access to 州巧's existing rack capacity. [src-083] [src-085]
  - Qualification: A newspaper report of Ablecom's announcement; the size of the shareholding is not stated.
  - Outcome: 州巧's own notice of August 21, 2026 records the private placement as completed and fully paid that day but does not name the subscriber.
- Documented: 州巧科技股份有限公司 announced on August 21, 2026 that it had completed its first private placement of 2026: 36,000,000 common shares at NT$28.92 per share, NT$1,041,120,000 in total, fully paid on 115年08月21日 (August 21, 2026). The notice does not name the subscriber. [src-085]

It funded the repayment of margin loans from two financial institutions secured by his Supermicro shares, which the lenders called in October 2018 after Nasdaq suspended trading in August 2018 and the share price fell. [src-014] [src-012]

- Attributed: A Taiwanese business weekly wrote in February 2024 that in 2018 a younger brother's wife (弟媳) lent US$12.9 million (about NT$390 million) to Supermicro to help the company repay bank loans. [src-058]
  - Qualification: The magazine's account differs from Supermicro's filings on the borrower and purpose: the filings describe a personal loan of about $12.9 million from Chien-Tsun Chang to CEO Charles Liang to repay his personal margin loans secured by Supermicro shares, not a loan to the company.
  - Outcome: The filings report that the personal loan was repaid in full on October 9, 2025.
- Documented: Supermicro discloses that in fiscal 2024 it made $0.5 million in sales to, and bought $0.1 million in products from, Green Earth Liang's Inc., an entity affiliated with CEO Charles Liang, and states that the sales were at market prices and on arm's length terms.

[src-081] [src-012] [src-042] [src-121]
  - Qualification: A short-seller allegation relying on media reports and unnamed former employees; it does not document the transactions it says went undisclosed.
  - Response: Supermicro's Special Committee concluded in December 2024 that the related parties named in the report had been disclosed as required, were not required to be disclosed or, in one case, had become a related party during fiscal 2024.
  - Outcome: Supermicro's annual report for fiscal 2024, filed in February 2025, disclosed that Ablecom and Compuware had acquired about 30% of Leadtek in October 2023 together with its transactions with Leadtek, and disclosed indirect sales of about $0.1 million to Aeon Lighting Technology Inc., a company owned more than 10% by the CEO's brother James Liang.

[src-002] [src-001]
- Documented: Monolithic Power Systems, Inc. (MPS) supplies high-performance analog and mixed-signal semiconductors used in Supermicro's products.

If the payments are accelerated after a default, Supermicro may seek reimbursement from the sublicensee. [src-012]
- Documented: Supermicro reported an equity investment of $42.5 million in the Vernon sublicensee at the end of fiscal 2024 and of $92.5 million in the "Sub-licensee" to which it subleased the entire Vernon space at the end of fiscal 2026. In both annual reports it states that the sublicensee does not meet the criteria of a related party, and that it has been a Supermicro customer; the company concluded that the equity investment and sublicensing agreements are separate from its revenue contracts because all transactions were recorded at their fair values.

  - Qualification: The EDGAR index lists the Item 4.02 report as filed on May 14, 2008. The amended quarterly report itself is not among the records reviewed.
  - Response: Supermicro said its management and Audit Committee had discussed the matter with its independent auditor, Deloitte & Touche LLP, and that it expected to report a material weakness in internal control over the classification of cash flows in the amended quarterly report.
- Documented: The EDGAR filing index lists two Supermicro current reports under Form 8-K Item 3.01 (the item used for notices concerning continued-listing standards) in April 2008, dated April 10, 2008 (together with Item 2.02) and April 22, 2008, a month before the May 2008 non-reliance report. [src-038]
  - Qualification: Only the index entries are retained; the content of the April 2008 notices is not among the records reviewed.
- Documented: In its amended report for the quarter ended March 31, 2017, filed after March 31, 2019, Supermicro stated that between late 2015 and 2017 it cooperated with an SEC investigation of marketing expenses that contained irregularities discovered by its management and disclosed on August 31, 2015. The EDGAR index lists a notice of late filing of the annual report (NT 10-K) dated August 31, 2015 and a notice of late filing of a quarterly report (NT 10-Q) dated November 10, 2015. [src-037] [src-046]
- Documented: In August 2017, before issuing its fiscal 2017 financial statements (year ended June 30, 2017), Supermicro's Audit Committee began an investigation into accounting and internal-control matters, principally revenue recognition, assisted by outside counsel and forensic accountants; expanded procedures and a management review of historical financial reporting followed. In the course of this work the Audit Committee and management determined that certain employees had violated the Code of Business Conduct and Ethics and discovered accounting and financial reporting errors and “certain irregularities”. [src-016]
- Documented: On November 14, 2018 Supermicro's board, on the Audit Committee's recommendation and in consultation with management, determined that the fiscal 2015 and 2016 financial statements and auditor's reports in the annual report, the quarterly reports for those years and the quarterly reports for the periods ended September 30, 2016, December 31, 2016 and March 31, 2017 should no longer be relied upon because of errors. The errors primarily concerned the timing of revenue recognition (quarter-end cut-off and allocation of revenue under contracts with service elements) and the classification of certain inventory. [src-040] [src-038]
  - Qualification: The current report (Items 2.02 and 4.02) was filed on November 15, 2018. It stated that, to date, none of the revenue-recognition errors identified involved revenue that could not ultimately be recognized.
- Documented: In the November 15, 2018 report Supermicro said it would report material weaknesses in internal control over financial reporting and ineffective disclosure controls in its fiscal 2017 annual report, that it had begun remediation, and that the Audit Committee had discussed the non-reliance disclosure with the independent registered public accounting firm. [src-040] [src-038]
- Documented: In preliminary results for the quarter ended September 30, 2018, released with the November 15, 2018 non-reliance report, Supermicro's expected non-GAAP earnings per share excluded $16.1 million of Audit Committee investigation and review expense; the company reported $104.1 million of cash, cash equivalents and short-term investments and $79.6 million of bank debt at September 30, 2018. [src-040]
- Documented: Before filing its fiscal 2017 annual report, Supermicro filed amended quarterly reports (Form 10-Q/A) with restated condensed financial statements for the quarters ended September 30, 2016, December 31, 2016 and March 31, 2017. The amendment for the March 31, 2017 quarter restated the balance sheets at March 31, 2017 and June 30, 2016 and the related statements, and superseded in its entirety the original report filed on May 10, 2017. [src-016] [src-046]
- Documented: Supermicro filed its annual report for fiscal 2017 (year ended June 30, 2017) on May 17, 2019. It was the first issuance of the fiscal 2017 financial statements and restated the balance sheet at June 30, 2016, the fiscal 2016 and 2015 statements of operations, comprehensive income, stockholders' equity and cash flows, and the selected financial data for those years. [src-016] [src-019]
- Documented: According to the restatement note in the fiscal 2017 annual report, the errors and certain irregularities primarily concerned the timing of recognition of revenue, of expenses for inventory used for engineering and marketing, and of warranty expenses for defective products not returned, as well as inventory derecognised although the company was obliged to buy it back. Product revenue for fiscal 2016 and 2015 had been recognised prematurely, which the note attributed in part to “an aggressive focus on quarterly revenue without sufficient focus on compliance”. The corrections increased fiscal 2016 net sales by $8.8 million and reduced fiscal 2015 net sales by $21.5 million; cost of sales rose by $11.1 million for 2016 and fell by $21.7 million for 2015. [src-016]
- Documented: Error corrections recorded in the three months ended June 30, 2016, similar in nature to those in the restatement note, increased net sales by $6.9 million and reduced gross profit by $2.9 million and net income by $1.5 million compared with the amounts previously reported for that quarter. [src-016]
- Documented: The fiscal 2017 annual report's statement of stockholders' equity shows cumulative restatement adjustments at June 30, 2014 that reduced retained earnings by $17,604 thousand and total stockholders' equity from $469,231 thousand as previously reported to $452,158 thousand as restated. [src-016]
- Documented: The SEC's 2020 order tabulates the net effect of the restatement (in thousands of dollars): fiscal 2015 net sales of $1,991,155 as reported against $1,954,353 as restated (−1.88%) and income from operations of $146,746 against $132,646 (−10.63%); fiscal 2016 net sales of $2,215,573 against $2,225,022 (+0.42%) and income from operations of $106,850 against $107,491 (+0.60%); fiscal 2017 net sales of $2,529,915 as first reported against $2,484,929 (−1.81%) and income from operations of $101,877 against $94,875 (−7.38%). [src-015]
  - Qualification: The order notes that these are net effects of reporting errors in their proper periods and that the gross effect in any single period was substantially larger.
- Documented: Supermicro reported large professional fees from the investigation and its aftermath: the fiscal 2017 annual report cited $40.6 million in fiscal 2018 and $50.7 million in the first three quarters of fiscal 2019 for the Audit Committee's investigation, procedures and analysis, audit and compliance work and related litigation; the fiscal 2019 annual report cited about $42 million in fiscal 2018 and about $67 million in fiscal 2019 for the work connected with the delayed 2017 annual report. Deloitte's audit fees rose from $2,427,000 for fiscal 2016 to $22,259,000 for fiscal 2017. [src-016] [src-044]
  - Qualification: The two annual reports define the scope of the fees differently, which explains the different fiscal 2018 figures.
- Documented: Because the fiscal 2017 annual report was not filed until May 17, 2019, owing among other matters to material weaknesses in internal control, Supermicro's Compensation Committee kept all named executive officers' base salaries for fiscal 2019 at fiscal 2018 levels while the review of those matters was still under way. [src-019]
- Documented: The fiscal 2017 annual report disclosed late ownership reports under Section 16(a) for that year: one each by Howard Hideshima, Sherman Tuan and Yih-Shyan (Wally) Liaw and by Phidias Chou (covering two transactions), and two by each of Charles Liang and Sara Liu, each covering one transaction. [src-016]
- Documented: During the investigation and restatement Supermicro filed ten notices of late filing listed in the EDGAR index: NT 10-K notices dated August 29, 2017, August 29, 2018 and August 30, 2019, and NT 10-Q notices dated November 13, 2017, February 9, 2018, May 10, 2018, November 13, 2018, February 14, 2019, May 10, 2019 and November 12, 2019. [src-037]
- Documented: The EDGAR index lists nine Supermicro current reports under Form 8-K Item 3.01 (continued-listing notices) during the reporting delay: September 15, 2017, November 20, 2017, February 21, 2018, March 16, 2018, May 21, 2018, July 13, 2018, August 21, 2018, August 23, 2018 and March 11, 2019. [src-038]
  - Qualification: Only the index entries are retained for these reports.
- Documented: Because it had not filed its periodic reports with the SEC and had not held an annual meeting, Supermicro could not meet Nasdaq listing standards: its common stock was suspended from trading on the Nasdaq Global Select Market effective August 23, 2018 and formally delisted effective March 22, 2019, after which it was quoted on the OTC Market under the symbol SMCI. The fiscal 2017 annual report, filed in May 2019, lists the stock as trading on OTC and answers “No” to whether the company had filed all required reports in the preceding 12 months. [src-016] [src-046] [src-062]
  - Outcome: Supermicro's common stock was relisted on the Nasdaq Global Select Market on January 14, 2020.
- Documented: In its fiscal 2020 annual report Supermicro stated that it did not intend to file a separate annual report for fiscal 2018 (year ended June 30, 2018) or quarterly reports for the quarters ended September 30, 2017, December 31, 2017 and March 31, 2018. [src-062]
- Documented: Supermicro became current in its SEC filings in December 2019, according to its 2020 proxy statement, and its stock returned to Nasdaq in January 2020; the SEC's 2020 order describes the stock as delisted from March 2019 through January 2020 and states that the company had since improved its internal controls and reorganized its management team. [src-019] [src-015]
- Documented: On August 25, 2020 the SEC instituted and simultaneously settled cease-and-desist proceedings against Super Micro Computer, Inc. (Securities Act Release No. 10822, Exchange Act Release No. 89656, Accounting and Auditing Enforcement Release No. 4161, Administrative Proceeding File No. 3-19927). The order found that the company engaged in improper accounting, prematurely recognizing revenue and understating expenses from at least fiscal 2015 through fiscal 2017, and as a result filed materially misstated financial statements with the Commission in its annual, quarterly and current reports. [src-015]
  - Qualification: Supermicro consented to the order without admitting or denying the findings, except as to the Commission's jurisdiction; the order states that its findings were made pursuant to the company's offer of settlement and are not binding on any other person or entity.
- Documented: The SEC order described the practices behind the misstatements: recognising revenue before goods were delivered or ahead of customer delivery dates; recording revenue on shipment to a large customer whose purchase orders specified FOB destination (more than $45 million recognised prematurely for that customer from fiscal 2015 through fiscal 2017); recognising revenue before customer acceptance; shipping incomplete or mis-assembled goods at quarter-end; recognising revenue on shipment to a large distributor that could pay only after its own sales; holding bills of lading for certain overseas customers, primarily in Russia and other Eastern European countries, until payment while booking revenue on shipment; recognising embedded extended-warranty revenue at sale; and under-reporting expenses by using cooperative marketing funds to pay unrelated costs. [src-015]
  - Qualification: These are the Commission's findings in a settled order; Supermicro neither admitted nor denied them.
- Documented: The SEC order found that Supermicro violated Sections 17(a)(2) and (3) of the Securities Act and Sections 13(a), 13(b)(2)(A) and 13(b)(2)(B) of the Exchange Act and Rules 12b-20, 13a-1, 13a-11 and 13a-13, ordered it to cease and desist and to pay a civil money penalty of $17,500,000.00 within 10 days, and created a Fair Fund for the penalty. The company agreed not to seek any offset of the penalty against compensatory damages in related private investor actions. In accepting the settlement the Commission considered the company's remedial acts. [src-015]
  - Qualification: Settled order; the company neither admitted nor denied the findings.
- Documented: According to the SEC order, Supermicro announced fourth-quarter fiscal 2017 results in a current report on August 3, 2017, said several weeks later that it could not file its fiscal 2017 annual report on time, and on September 15, 2017 disclosed an audit committee review. In November 2018 it determined that its financial statements for fiscal 2015 through 2017 could not be relied upon, and it filed no annual or quarterly report from its third-quarter fiscal 2017 report until May 2019, when it filed the fiscal 2017 annual report and amended the quarterly reports for the first three quarters of fiscal 2017. [src-015]
- Documented: The penalties, disgorgement and interest paid by Supermicro and Hideshima were combined into a Fair Fund of $17,851,056.00 for investors harmed by the conduct described in the orders; the SEC states that both respondents paid in full. It appointed Miller Kaplan Arase LLP as tax administrator (November 6, 2020) and Kurtzman Carson Consultants, LLC as fund administrator (December 22, 2020), approved a plan of distribution on April 8, 2021 (Release No. 34-91507) and amended it on February 7, 2022 (Release No. 34-94170). An order of December 20, 2023 (Release No. 34-99215) approved payment of $455,627.22 from the fund for the administrator's services from December 22, 2020 to July 31, 2023. [src-055] [src-082]
- Documented: Supermicro's fiscal 2020 annual report states that its Chief Executive Officer concluded a settlement with the SEC on August 25, 2020 under which he would pay the company $2,122,000 as reimbursement of profits from certain stock sales during the relevant period, pursuant to Section 304 of the Sarbanes-Oxley Act of 2002; the fiscal 2021 report states that the amount was paid during the first quarter of fiscal 2021. A September 30, 2026 order of the U.S. District Court for the Northern District of California in the securities class action In re Super Micro Computer, Inc. Securities Litigation (No. 5:24-cv-06147), summarising an SEC document it took judicial notice of, states that Howard Hideshima paid disgorgement to resolve the SEC matter and that Charles Liang agreed to reimburse Supermicro $2.1 million in stock compensation. [src-072] [src-062] [src-061]
  - Qualification: The SEC's own document on this settlement is not among the records reviewed; the court describes the amount as stock compensation, the company as profits from stock sales. The records contain no SEC finding of misconduct by Charles Liang himself.
- Documented: In its amended quarterly report for the quarter ended March 31, 2017, filed after March 31, 2019, Supermicro disclosed that it had received SEC subpoenas in connection with the matters underlying its inability to file the fiscal 2017 annual report on time and said it was cooperating fully with these requests. [src-046]
- Attributed: In the same amended quarterly report Supermicro stated that it had also received an SEC subpoena following October 2018 Bloomberg Businessweek reporting concerning its products, which the company described as false and widely discredited. Its fiscal 2017 annual report describes the article as alleging that malicious hardware chips were implanted on Supermicro motherboards during manufacturing at the facilities of a contract manufacturer in China. [src-046] [src-016] [src-062]
  - Qualification: The characterisation of the reporting is Supermicro's own. The article itself is not among the records reviewed, which establish nothing about its accuracy; the SEC's August 2020 order does not mention it.
  - Response: Supermicro states that a third-party investigations firm tested a representative sample of its motherboards, including the type shown in the article, and found no evidence of malicious hardware, and that neither the publication nor any customer had provided an example of an altered motherboard.
  - Outcome: Supermicro's fiscal 2020 annual report states that it cooperated with the SEC's investigation concerning the article and that on August 25, 2020 it consented to the SEC's cease-and-desist order to fully resolve all matters under investigation.
- Documented: Deloitte & Touche LLP's audit report in the fiscal 2017 annual report, dated May 16, 2019 (San Jose), stated that the 2016 and 2015 consolidated financial statements had been restated to correct misstatements and drew attention to the company's significant purchases from and sales to two related parties. [src-016]

## Internal control over financial reporting, fiscal 2017–2026

- Documented: Supermicro's management concluded that internal control over financial reporting was not effective at June 30, 2017 because of material weaknesses. Deloitte & Touche LLP's report on internal control described a culture of aggressively focusing on quarterly revenue without sufficient focus on compliance, a failure of senior management to set an appropriate tone, and sales, finance and operations personnel, including officers and managers, who were aware of, condoned or were involved in actions that reflected an inappropriate tone at the top and violated the Code of Conduct and accounting policies; it added that some employees failed to raise material accounting issues with the Audit Committee and the auditor and, for one transaction, appear to have tried to minimise or obscure material facts from them. [src-016]
- Documented: In its fiscal 2019 annual report Supermicro's management did not conclude that any material weakness identified in the 2017 annual report had been remediated at June 30, 2019, because new controls had not operated long enough; deficiencies in the control environment and other components remained. Deloitte & Touche LLP, in reports dated December 19, 2019, gave an adverse opinion on internal control at June 30, 2019 and an unqualified opinion on the fiscal 2019 financial statements, with an explanatory paragraph on the adoption of the new revenue standard (ASC 606). [src-044]
- Documented: Remediation steps reported in the fiscal 2019 annual report included restructuring the sales organization, which led to the resignations of the senior vice presidents of international sales and of worldwide sales, the vice presidents of strategic accounts, strategic sales and business development and certain other sales staff; appointing a new Chief Financial Officer and Corporate Controller in January 2018; and creating the posts of Chief Compliance Officer (May 2018) and Vice President of Internal Audit (August 2018). [src-044]
- Documented: In its fiscal 2020 annual report Supermicro stated that it had remediated the material weaknesses related to all five COSO components of internal control and to revenue-recognition accounting controls, but its CEO and CFO concluded that disclosure controls were not effective at June 30, 2020 because of a remaining material weakness in information technology general controls. Deloitte & Touche LLP's report dated August 28, 2020 expressed an adverse opinion on internal control over financial reporting at that date. [src-062] [src-061]
- Documented: For fiscal 2021 Supermicro's management concluded that internal control over financial reporting was effective at June 30, 2021 after remediating the IT general-controls weakness reported for fiscal 2020, and Deloitte & Touche LLP, in reports dated August 27, 2021, issued unqualified opinions on internal control and on the fiscal 2021 financial statements. [src-061]
- Documented: In October 2021 Supermicro's Compensation Committee awarded discretionary one-time bonuses of $160,000 to David Weigand, $150,000 to Don Clegg and $40,000 to George Kao, primarily to recognise progress in remediating the material weaknesses in internal control over financial reporting. [src-014]
- Documented: Supermicro's fiscal 2021 annual report lists its executive officers at July 31, 2021 as Charles Liang (President, Chief Executive Officer and Chairman), David Weigand (Senior Vice President, Chief Financial Officer and Chief Compliance Officer), Don Clegg (Senior Vice President of Worldwide Sales), George Kao (Senior Vice President of Operations) and Sara Liu (Co-Founder, Senior Vice President and Director); the independent directors were Daniel W. Fairfax, Saria Tseng, Sherman Tuan, Shiu Leung (Fred) Chan and Tally Liu, with Fairfax, Chan and Liu on the Audit Committee. [src-061]
- Documented: Supermicro concluded that internal control over financial reporting was not effective at June 30, 2024 because of five material weaknesses: information technology general controls; segregation-of-duties controls; controls over manual journal entries; documentation of controls over the completeness and accuracy of information; and documentation of controls for timely, complete and accurate recording and disclosure, including the timely identification and disclosure of new leasing arrangements and new related-party transactions. None had been remediated when the annual report was filed. BDO's report of February 25, 2025 expressed an adverse opinion on internal control and an unqualified opinion on the fiscal 2024 financial statements, stating that BDO had served as auditor since 2024. [src-012]
- Documented: For fiscal 2025 Supermicro reported four unremediated material weaknesses at June 30, 2025 (information technology general controls; segregation of duties; completeness and accuracy of information; and documentation of controls for timely recording and disclosure, including the timely identification and disclosure of new related-party transactions), while stating that it had remediated the manual-journal-entry weakness and had promoted its controller to Chief Accounting Officer. BDO's report of August 28, 2025 gave an unqualified opinion on the financial statements and an adverse opinion on internal control at June 30, 2025. [src-121]
- Documented: For fiscal 2026 Supermicro reported that it had remediated the segregation-of-duties, information-completeness and recording-and-disclosure weaknesses, including through a full redesign of its ERP security roles, but that the information technology general controls weakness remained unremediated, so internal control over financial reporting was not effective at June 30, 2026. BDO's report of August 31, 2026 gave an adverse opinion on internal control and an unqualified opinion on the financial statements. The annual report's Item 9 reports no changes in or disagreements with accountants. [src-002]

## Deloitte, EY and BDO: the auditor changes of 2023–2025

- Documented: Deloitte & Touche LLP audited Supermicro from fiscal 2003. On March 9, 2023 the Audit Committee approved engaging Ernst & Young LLP (EY) for the fiscal year ending June 30, 2024; Deloitte continued for fiscal 2023 and was dismissed effective on completion of that audit. Supermicro's current report stated that Deloitte's reports for fiscal 2022 and 2021 contained no adverse opinion or disclaimer and were not qualified, and that there were no disagreements or reportable events with Deloitte under Item 304 of Regulation S-K. [src-031] [src-032] [src-014] [src-041]
  - Qualification: In its letter to the SEC of March 14, 2023 (Exhibit 16.1), Deloitte agreed with the second to fourth paragraphs of the company's disclosure and had no basis to agree or disagree with the first and fifth. The change was reported in a current report filed on March 15, 2023.
- Documented: For fiscal 2023 Supermicro's management concluded that internal control over financial reporting was effective at June 30, 2023, and Deloitte & Touche LLP, in reports dated August 25, 2023, issued unqualified opinions on internal control and on the fiscal 2023 financial statements; the annual report stated that past material weaknesses had been remediated. The fiscal 2024 annual report reproduces Deloitte's August 25, 2023 report as that of the predecessor auditor, noting that Deloitte began serving in 2003 and became the predecessor auditor in 2023. [src-045] [src-012]
- Documented: Audit fees disclosed by Supermicro were, in thousands of dollars: Deloitte $5,053 for fiscal 2018 and $7,178 for fiscal 2019, $4,405 for fiscal 2021 and $4,488 for fiscal 2022, and $4,756 for fiscal 2023; BDO $8,000 for fiscal 2024 in the fiscal 2024 annual report, while the 2026 proxy statement reports BDO audit fees of $8,578 for fiscal 2024 and $8,084 for fiscal 2025. [src-019] [src-012] [src-014] [src-001]
  - Qualification: The two documents do not explain the difference between the fiscal 2024 BDO figures. No EY fees appear in the retained fee tables.
- Documented: Supermicro's Audit Committee report on fiscal 2022, included in its 2023 proxy statement, was furnished by Tally Liu (chair), Daniel Fairfax and Fred Chan. [src-014]
- Documented: In its October 30, 2024 current report on EY's resignation, signed by Charles Liang, Supermicro said it did not expect the matters raised by EY, or under review by the Special Committee, to result in any restatement of its fiscal 2024 quarterly reports or of prior fiscal years. Its later proxy statement states that, other than as described, there were no “disagreements” with EY and no “reportable events” under Item 304 of Regulation S-K for fiscal 2023, fiscal 2024 and the period before the resignation. [src-028] [src-001]
- Documented: In its letter to the SEC of October 29, 2024 (Exhibit 16.1 to the company's Item 4.01 report), EY said it agreed with the first paragraph, the first sentence of the second paragraph, the third paragraph, the first three sentences of the fourth paragraph and the fifth, seventh and eighth paragraphs of Supermicro's disclosure, and had no basis to agree or disagree with the company's other statements. [src-029] [src-028]
  - Qualification: The retained letter does not say which company statements fall into the second group.
- Documented: Supermicro's Special Committee consisted of one independent director, Susie Giordano (Susan Mogensen), an attorney who joined the board in August 2024 specifically to lead it. With outside counsel Cooley LLP and forensic accountants Secretariat Advisors, LLC it investigated the rehiring of employees who had resigned in 2018 after the 2017 Audit Committee investigation, current sales and revenue-recognition practices, export-control matters and related-party disclosures, reviewing about 4.1 terabytes of data and conducting 68 witness interviews. [src-042]
- Attributed: The Special Committee examined the rehiring of nine people, as employees or contractors, who had resigned after the 2017 Audit Committee investigation. It found the rehiring decisions reasonable business judgment and the processes generally appropriate, but identified lapses, for which the CFO/Chief Compliance Officer, then David Weigand, had primary responsibility: among them, the Audit Committee or the auditor was not always informed promptly, including EY not being told before the company entered, in June 2024, into a since-terminated consulting arrangement with its former CFO who had resigned after the 2017 investigation. [src-042]
  - Qualification: Findings of the board's Special Committee as announced by Supermicro. The company's announcement does not name the former CFO, and this dossier does not identify that person.
  - Response: The committee found no evidence that any lapse resulted from bad faith, improper motives or disregard for accurate financial reporting or compliance by the CFO/CCO or anyone else.
- Attributed: Reviewing 52 sales transactions from April 1, 2023 to June 30, 2024, including two specifically designated by EY, the Special Committee did not disagree with any of Supermicro's revenue-recognition conclusions for any quarter in that period and found no evidence of a pattern or practice of shipping incomplete products at or near quarter-ends to recognize revenue. [src-042]
  - Qualification: Conclusions of the board's Special Committee as announced by the company, based on a sample selected by the committee.
- Attributed: The Special Committee reviewed 11 export transactions noted by EY and export-control allegations in a short-seller report released on August 27, 2024. It reported seeing no evidence that anyone at Supermicro tried to circumvent export controls or knew products might be diverted to a prohibited end user or location, and no products sold to Russian customers or shipped to Russia in violation of the export controls or sanctions in force at shipment. On related parties named in the short-seller report, it concluded they had been fully disclosed, did not require disclosure or, in one case, had become a related party during fiscal 2024 and would be disclosed in the annual report. [src-042] [src-007]
  - Qualification: Conclusions of the board's Special Committee as announced by the company; the short-seller report's own assertions are set out separately as allegations. In March 2026 federal prosecutors charged a co-founder and others with diverting servers to China from 2024 onward; the committee's December 2024 announcement did not refer to that conduct.
- Documented: Supermicro's board adopted all of the Special Committee's recommendations, announced on December 2, 2024: to appoint a new Chief Financial Officer with large-public-company experience (David Weigand to remain CFO until a successor was named), a Chief Accounting Officer, a separate Chief Compliance Officer (the committee found that combining the CFO and compliance roles for longer than anticipated had impaired oversight of guardrails for rehired employees), and a General Counsel with an expanded legal department, and to improve training and guardrail monitoring. [src-042]
- Documented: Supermicro's Audit Committee appointed BDO USA, P.C. as independent auditor for fiscal 2024 on November 18, 2024 (reported in a current report under Items 4.01 and 8.01 filed that day), for fiscal 2025 on March 16, 2025, and for the fiscal year ending June 30, 2026; BDO audited the fiscal 2024 and 2025 financial statements. [src-001] [src-041]
- Documented: Because of EY's stated concerns and resignation, Supermicro could not file on time its fiscal 2024 annual report and its quarterly reports for the quarters ended September 30 and December 31, 2024, as Nasdaq Listing Rule 5250(c)(1) requires. It filed notices of late filing on August 30, 2024 (annual report), November 13, 2024 and February 11, 2025 (quarterly reports). On December 6, 2024 Nasdaq granted an exception allowing the delinquent reports to be filed by February 25, 2025, and all three were filed on February 25, 2025. [src-012] [src-001] [src-037] [src-042]
  - Response: In its December 2, 2024 announcement Supermicro said that, as announced on November 18, 2024 in its compliance plan to Nasdaq, it believed it would be able to complete its fiscal 2024 annual report and its report for the quarter ended September 30, 2024.
- Documented: The EDGAR index lists Supermicro current reports under Form 8-K Item 3.01 (continued-listing notices) dated September 20, 2024, November 20, 2024 (with Items 1.01 and 2.03), December 6, 2024 and February 26, 2025 (with Items 5.08 and 8.01), the day after the delinquent reports were filed. [src-041]
  - Qualification: Only the index entries are retained for these reports. A further Item 3.01 report of May 9, 2024 concerned the composition of the Audit Committee.
- Documented: Because it did not file its fiscal 2024 annual report on time, Supermicro elected to accrue special interest, and accrued additional interest, on its 2029 Convertible Notes under the terms of the indenture. [src-012]

## Export controls: from Iran in 2006 to Taiwan in 2026

- Documented: Supermicro's annual reports state that it historically sold products into Russia before broad sanctions were imposed, last recorded revenue from Russia on February 23, 2022, and no longer sells products or provides services there. In a disclosure under Section 13(r) of the Exchange Act in its fiscal-2023 annual report, it said that before the Russian Federal Security Service (FSB) was designated a blocked party on March 2, 2021 it had authorised third parties to file notifications with, or apply for import licences from, the FSB on its behalf for importing its products into Russia; during fiscal 2023 third parties filed notifications, applied for licences and/or received approvals on its behalf, dealings that OFAC's General License No. 1B authorises, subject to limitations. [src-045] [src-012]
  - Qualification: The disclosure is the company's own account; it states that no sales occurred in Russia in fiscal 2023, that the filings produced no revenue, that it believes it has terminated the authorisations and that it does not sell to or serve the FSB.
- Documented: The indictment and the Justice Department release do not name the manufacturer. Supermicro's annual report for fiscal 2026 states that 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" for an alleged conspiracy to commit export control violations, and refers to them as "three former associates". The company received a grand jury subpoena from that office for documents on the individuals and facts in the indictment and on its compliance program and internal controls. [src-002]
  - Qualification: Supermicro itself is not charged in the indictment.
- Documented: Supermicro's annual report for fiscal 2025 (year ended June 30, 2025) states that 59.4% of its revenue for that year came from the United States and 10.9% from Thailand; in fiscal 2024 and fiscal 2023, 68.0% and 67.9% came from the United States and no other country accounted for 10% or more. [src-121]
  - Qualification: The report does not identify the customers behind the Thailand revenue.
- Documented: Supermicro states that because it exports restricted GPUs it routinely receives subpoenas and other requests from the Office of Export Enforcement for information about customers or contemplated transactions, that it was responding to a number of such requests, that several earlier requests remained open, and that it had not been informed it was the target of any of them; if it became a target, OEE could pursue a civil enforcement action, seek penalties or require changes to its compliance program. [src-002]
- Attributed: According to the Keelung prosecutors, a Taiwanese technology company that had obtained whitelist status used false end-use and end-user declarations (stating Taiwan as the installation country), a staged data-centre inspection and the listed distributor's funding to buy 130 Nvidia B300 servers from Supermicro's Taiwan subsidiary in three deliveries from September 2025. Seventy-four servers were exported in early 2026 to customers in China, directly or via Indonesia, Japan and Hong Kong; 56 were stopped when customs required an export licence and an application supported by fabricated pages from Supermicro's website was filed. The prosecutors put the organisers' illegal profit at US$21,205,531 and say the two sales directors received sales bonuses of US$62,804 and US$83,872 from the Taiwan subsidiary for the order. [src-098]
  - Qualification: These are prosecutors' allegations in a press release announcing the indictment; no court has ruled on them.
- Attributed: The Keelung prosecutors state that the defendants' conduct damaged the U.S. server maker and the GPU designer: the server maker's reputation suffered, its share price fell, its export products were placed under mandatory inspection, and delayed deliveries forced it to pay penalties to customers. The prosecutors describe both companies as maintaining strict internal controls on buyers' qualifications and product end-use. [src-098]
  - Qualification: This is the prosecutors' characterisation in their release; the companies are not parties to the indictment and the damage figures are not quantified.
- Attributed: The Keelung prosecutors further charge one of the two Supermicro Taiwan sales directors, the distributor's general manager and a third person with special breach of trust under the Securities and Exchange Act, alleging that between January and April 2026 four false invoices caused the listed distributor to pay NT$39,158,514 to a company that provided no services. They asked the court to impose the statutory maximum of five years' imprisonment on both sales directors for the export conduct and six years on the first director for the asset-stripping charge. [src-098]
  - Qualification: These are prosecutors' charges and sentencing requests; no court has ruled.
- Unresolved: A Taiwanese technology news outlet reported on June 30, 2026 that on June 29 the Keelung prosecutors, in a second wave of their investigation into suspected illegal export of AI servers with Nvidia GPUs to China, Hong Kong and Macau, searched Supermicro's Taiwan branch and two other companies, a listed technology company and a data-centre operator, and questioned managers; a first wave in May 2026 had searched 12 locations linked to three people. [src-107] [src-106]
  - Qualification: The accounts conflict: the outlet reported a search of Supermicro's Taiwan branch, while Supermicro's July 1, 2026 letter said its Taiwan offices were not raided and that it gave authorities access to the detained employees' desks and devices. The records reviewed do not resolve the difference.

## The 2026 Liaw export-diversion case

- Documented: The docket of United States v. Liaw, No. 1:26-cr-00100 (S.D.N.Y.), assigned to Judge Edgardo Ramos, shows the indictment filed under seal on March 17, 2026 and unsealed on March 19, 2026. On April 1, 2026 Liaw and Sun were arraigned on all three counts; a two-week jury trial was first set for November 2, 2026. At a status conference on June 10, 2026 the court reset jury selection and trial for March 29, 2027. Under an October 1, 2026 scheduling order the government's opposition to Liaw's Rule 12 pretrial motions was due October 20, 2026 and his reply November 3, 2026. [src-068]
  - Response: Liaw and Sun entered pleas of not guilty on April 1, 2026.
  - Outcome: Liaw remained on bail; no verdict had been reached on the charges against him at the October 2026 cutoff.
- Documented: The docket of United States v. Liaw records the arrests of Liaw and Sun in the Northern District of California on March 19, 2026, but through its last entry on October 15, 2026 shows no arrest, appearance or counsel for Ruei-Tsang "Steven" Chang, whom the March 19, 2026 Justice Department release described as remaining a fugitive. [src-068] [src-007]
  - Qualification: Chang has not appeared to answer the charges, which remain unproven allegations.
- Documented: On October 6, 2026 the court unsealed a superseding information against Ting-Wei "Willy" Sun, filed under seal on September 8, 2026, with four counts: conspiracy to violate the Export Control Reform Act, conspiracy to smuggle goods from the United States, conspiracy to defraud the United States by impeding the Commerce Department, and obstruction of justice for deleting an encrypted messaging application and its contents from his phone on March 19, 2026. On October 8, 2026 Sun waived indictment and pleaded guilty to all four counts; sentencing is set for September 8, 2027. [src-068] [src-069]
  - Outcome: Guilty plea entered October 8, 2026; sentence not yet imposed.
- Attributed: A technology news site reported on May 8, 2026, citing a news agency's report based on unnamed sources, that the "Company-1" of the indictment of Supermicro co-founder Yih-Shyan "Wally" Liaw is OBON Corp., a Bangkok-based AI infrastructure firm that has been a public partner of Thailand's National AI Strategy. [src-073]
  - Qualification: This identification comes from a press report relying on unnamed sources; the indictment, the superseding information and the Justice Department release do not name Company-1, and no court record reviewed establishes its identity.
  - Response: The report said OBON had not commented at the time of publication.
  - Outcome: The report said OBON had not been charged and that prosecutors were continuing to examine the role of the ends of the diversion chain.

## Lawsuits by shareholders and a former employee

- Documented: Supermicro's fiscal-2026 annual report discloses that it received an SEC subpoena for documents on certain customers, including one customer that is the subject of the indictment's allegations, and on its controls and procedures; a grand jury subpoena from the U.S. Attorney's Office for the Southern District of New York; and other subpoenas and inquiries from the Justice Department, the Office of Export Enforcement (OEE) of BIS and foreign authorities about certain other customers. The company says it is cooperating and has not been informed that it is the target of any of these investigations. [src-002]
  - Qualification: The disclosure does not state any charge or finding against the company.
- Documented: In the federal derivative case in the Northern District of California, the court granted Yih-Shyan Liaw's motion to substitute counsel on April 28, 2026 and admitted Nelson Boxer to appear for him pro hac vice on May 8, 2026. On October 8, 2025 the lawyers who had appeared for the company in April 2025 had also appeared for Liaw and the other individual defendants. [src-086]
- Documented: On September 30, 2026 Judge Edward J. Davila granted the motion of Supermicro, Charles Liang and David Weigand to dismiss In re Super Micro Computer, Inc. Securities Litigation, No. 5:24-cv-06147-EJD, with leave to amend. The court held that the lead plaintiff had not pleaded with the particularity required by the Private Securities Litigation Reform Act facts showing that Supermicro's statements on the remediation of earlier internal control deficiencies were false or misleading, and did not reach scienter or loss causation. It found that Ernst & Young's resignation letter reflected disagreements with management but identified no specific internal control deficiency, and set October 21, 2026 as the deadline for an amended complaint. [src-072]
  - Qualification: This is a ruling on the sufficiency of the pleadings, not a finding on the merits; the court allowed the plaintiff to amend.
- Attributed: Further derivative suits followed: Anderson v. Liang, C.A. No. 2025-0986-KSJM, filed in the Delaware Court of Chancery on August 29, 2025 against current and former directors and officers, with Mathiyalagan v. Liang (filed January 6, 2026) consolidated into it on May 8, 2026 and a suit by the Employees' Retirement System of the State of Rhode Island and Bucks County Employees' Retirement System, first filed in the Northern District of California on January 29, 2026 and refiled in Delaware on May 29, 2026, consolidated on August 18, 2026. In the Northern District of California, Pill v. Liang (May 19, 2026), City of Birmingham Retirement and Relief Systems v. Liang (June 24, 2026), Cepeda v. Liang (July 10, 2026) and Roy v. Liang (August 21, 2026) were filed. [src-002]
  - Qualification: These are shareholders' allegations; no court has ruled on them.
  - Response: Supermicro's fiscal-2026 annual report calls the matters too preliminary to judge the likelihood of an adverse outcome or estimate any loss.
- Attributed: On November 22, 2024 a putative class action, 1000099739 Ontario Ltd. v. Super Micro Computer, Inc., No. CV-24-00731863-OOCP, was filed against Supermicro in the Ontario Superior Court of Justice, alleging common-law primary and secondary market misrepresentation and violations of the Ontario Securities Act through misstatements or omissions about its financial results and internal controls. [src-002] [src-121] [src-105]
  - Qualification: These are plaintiffs' allegations; no court has found them to be true. Supermicro's December 29, 2025 credit-agreement schedule still lists the claim, recording only that the hearing on the motion to dismiss was held on December 8, 2025.
  - Response: Supermicro moved on August 1, 2025 to dismiss the claim for lack of jurisdiction, with the hearing set for December 8, 2025.
  - Outcome: The plaintiff dismissed the claim on December 8, 2025.
- Documented: In Luong v. Super Micro Computer, Inc., Judge Beth Labson Freeman on November 4, 2024 compelled arbitration of Luong's state-law claims and stayed the case; Luong then dropped those claims to proceed only on his Sarbanes-Oxley claim, and the stay was lifted. On June 17, 2025 Judge Noël Wise denied in full the motion of Supermicro and Liang to dismiss, finding Luong's administrative complaint to OSHA timely and Liang adequately notified. The court set a six-day jury trial for September 21, 2026, referred the case to private mediation on September 23, 2025 and on September 26, 2025 refused the parties' request to move the trial later. On March 3, 2026 the parties filed a stipulation of dismissal with prejudice, and the case was terminated on April 23, 2026. [src-075] [src-089] [src-090] [src-109] [src-110]
  - Outcome: Dismissed with prejudice by stipulation before trial; the terms are not in the docket.
- Attributed: Two shareholder derivative suits were filed over Supermicro's revenue-recognition statements, internal controls and late SEC filings: Barry v. Liang, No. 20-CV-372190, in the Superior Court of California, County of Santa Clara, on October 27, 2020, and Stein v. Liang, No. 3:21-cv-03357-KAW, in the U.S. District Court for the Northern District of California, on May 5, 2021. Each named certain current and former directors and officers as defendants and Supermicro as nominal defendant, alleging breaches of fiduciary duty, waste of corporate assets and unjust enrichment (and, in Stein, contribution for violations of federal securities laws) on the theory that they caused Supermicro to issue false and misleading statements about revenue recognition and the effectiveness of its internal controls, failed to implement effective internal controls and failed to file reports with the SEC on time. [src-061]
  - Qualification: These were the shareholders' allegations. The annual report describing the suits does not name the individual defendants, and no later retained record mentions either suit, so their outcome is not known from the records reviewed.
  - Response: The defendants demurred in Barry (the plaintiff amended the complaint in July 2021 and a further demurrer was set for hearing on November 24, 2021) and moved to dismiss Stein on August 6, 2021; Supermicro said it intended to defend each lawsuit vigorously.

## The August 2024 short-seller report and the answers to it

- Documented: Supermicro discloses that on November 19, 2024 it received a subpoena from the SEC's Enforcement staff in an investigation entitled In the Matter of Super Micro Computer, Inc., seeking categories of documents many of which overlap with requests in October 22, 2024 subpoenas from the U.S. Attorney's Office for the Southern District of New York and with allegations in an August 27, 2024 report by the short seller Hindenburg Research; it received another SEC subpoena on April 28, 2026. The company says it is cooperating and continues to produce documents. [src-002] [src-105]
  - Qualification: A subpoena is a request for documents in an investigation, not a charge or finding. The schedules to Supermicro's December 29, 2025 credit agreement state that no charges had been reported by then.
- Attributed: The Hindenburg report alleged that less than three months after paying its $17.5 million SEC settlement in 2020, Supermicro began rehiring senior employees who had been directly involved in its earlier accounting problems, and that three senior employees who left in early 2018 had come back as a board member, a consultant working close to the CEO and a vice president of business development. [src-081] [src-042]
  - Qualification: A short-seller allegation based on litigation records and interviews with unnamed former employees; the report's description of those individuals' involvement in the earlier accounting problems is not adopted.
  - Response: Supermicro's Special Committee reported in December 2024 that it had examined the rehiring of nine individuals, as employees or independent contractors, who had resigned after the 2017 Audit Committee investigation. It noted that the 2017 investigation had made no finding that they engaged in conduct intended to misstate the company's results, concluded that the decisions to rehire them were the product of reasonable business judgment, and found lapses in keeping guardrails in place and in informing the Audit Committee and the auditor.
- Attributed: The report also alleged, citing former employees and customers and a lawsuit filed in April 2024, that after the SEC settlement quota pressure led Supermicro salespeople to push products to distributors through partial shipments or by shipping defective products around quarter-end. [src-081]
  - Qualification: A short-seller allegation from unnamed former employees and customers; it does not identify specific transactions or amounts.
  - Response: Supermicro's Special Committee reported in December 2024 that, having reviewed 52 sales transactions from April 1, 2023 to June 30, 2024, including two specifically designated by the former auditor Ernst & Young, it did not disagree with any of the company's revenue recognition conclusions for any quarter in that period.
- Attributed: The report alleged, from its review of more than 45,000 import and export transactions, that exports of Supermicro components to Russia had roughly tripled since the February 2022 invasion of Ukraine in apparent violation of U.S. export bans, that the goods moved first through a California distributor and later through newly formed Turkish and Hong Kong companies, and that at least 46 companies that handled Supermicro products bound for Russia were under OFAC sanctions or on U.S. government watch lists. [src-081] [src-042]
  - Qualification: A short-seller allegation based on third-party customs data that are not part of the records reviewed here; it describes Supermicro products reaching Russia through other companies, not sales recorded by Supermicro to Russian customers.
  - Response: Supermicro states that it no longer sells products or provides services to Russia and last recorded revenue from Russia in February 2022. Its Special Committee reported in December 2024 that it did not identify products sold to Russian customers or shipped to Russia in violation of export controls or sanctions in place when the products were shipped.
