Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation and claims On August 30, 2024, three putative class action complaints were filed against the Company, the Company’s Chief Executive Officer, and the Company’s Chief Financial Officer in the U.S. District Court for the Northern District of California (Averza v. Super Micro Computer, Inc., et al., No. 5:24-cv-06147, Menditto v. Super Micro Computer, Inc., et al., No. 3:24-cv-06149, and Spatz v. Super Micro Computer, Inc., et al., No. 5:24-cv-06193). On October 4, 2024, a fourth putative class action complaint was filed in the same court (Norfolk County Retirement System v. Super Micro Computer, Inc., et al., No. 5:24-cv-06980). On October 18, 2024, a fifth putative class action complaint was filed in the same court (Covey Financial Inc., et al. v. Super Micro Computer, Inc., et al., No. 5:24-cv-07274). The complaints contain similar allegations, claiming that (i) each of the defendants violated Section 10(b) of the Securities Exchange Act and Rule 10b-5 promulgated thereunder and (ii) each of the Company’s Chief Executive Officer and the Company’s Chief Financial Officer violated Section 20(a) of the Securities Exchange Act as controlling persons of the Company for the alleged violations under (i), due (in each case) to alleged misrepresentations and/or omissions in public statements regarding the Company’s financial results and its internal controls and procedures. On October 28, 2024, the Spatz plaintiff voluntarily dismissed the Spatz complaint without prejudice against all Defendants, ending the suit. On November 21, 2024, the Averza Court entered a Stipulation and Order extending Defendants’ time to respond to the Averza complaint until after the Court appoints a lead plaintiff, which hearing is set for March 6, 2025. A similar stipulation was entered among the parties as to the Covey Financial complaint. On January 9, 2025, the Menditto plaintiff voluntarily dismissed the Menditto complaint without prejudice against all Defendants, ending the suit. The Company has not been served with the Norfolk County Retirement System complaint. These matters are too preliminary to form a judgment as to whether the likelihood of an adverse outcome is probable and the Company is unable to estimate the possible loss or range of loss, if any. On September 11, 2024, certain current and former directors and certain current officers of the Company were named as defendants in a putative derivative lawsuit filed in the U.S. District Court for the Northern District of California, captioned Hollin v. Liang, et al., Case No. 5:24-cv-06410 (the “Hollin Action”). Four additional putative derivative lawsuits have been filed in the same court, captioned Latypov v. Liang, et al., Case No. 5:24-cv-06779 (filed Sept. 26, 2024), Keritsis v. Liang, et al., Case No. 5:24-cv-07753 (filed Nov. 6, 2024), Roy v. Liang, et al., Case No. 5:24-cv-08006 (filed Nov. 14, 2024), and Jha v. Liang, et al., No. 5:24-cv-08792 (filed Dec. 5, 2024) (together with the Hollin Action, the “Federal Derivative Litigation”). On November 20, 2024, certain current and former directors and certain current officers of the Company were named as defendants in a putative derivative lawsuit filed in the Superior Court of California, County of Santa Clara, captioned Spatz v. Liang, et al., Case No. 24CV452241 (the “Spatz Action”). Two additional putative derivative lawsuits have been filed in the same court, captioned Clark v. Liang, et al., Case No. 24CV454416 (filed Dec. 17, 2024) and Carter, et al. v. Liang, et al., Case No. 24CV454689 (filed Dec. 20, 2024) (together with the Spatz Action, the “State Court Derivative Litigation,” and together with the Federal Derivative Litigation, the “Derivative Litigation”). The Company was named as a nominal defendant in the Derivative Litigation. The Federal Derivative Litigation purports to allege claims for breaches of Sections 10(b), 14(a), and 20(a) of the Securities Exchange Act of 1934, as amended, and Rules 10b-5 and 14a-9 promulgated thereunder, breach of fiduciary duty, aiding and abetting breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, and contribution arising out of allegations that the Company’s officers and directors caused the Company to issue materially false and misleading statements concerning the Company’s business operations and financial results. The State Court Derivative Litigation purports to allege claims for breach of fiduciary duty, aiding and abetting breach of fiduciary duty, waste of corporate assets, unjust enrichment, and insider trading arising out of similar allegations as the Federal Derivative Litigation. The plaintiffs in the Derivative Litigation seek unspecified money damages, in addition to punitive damages and other relief. On November 5, 2024, the Court in the Hollin Action entered a Stipulation and Order staying all proceedings in Hollin and any related federal derivative actions, which includes the Federal Derivative Litigation. The Court in the State Court Derivative Litigation stayed all proceedings until case management conferences were held in each suit, with the first conference scheduled for April 24, 2025 in Spatz. These matters are too preliminary to form a judgment as to whether the likelihood of an adverse outcome is probable and the Company is unable to estimate the possible loss or range of loss, if any. On November 22, 2024, a putative class action claim was filed against the Company in Ontario Superior Court of Justice, Canada, captioned 1000099739 Ontario Ltd. v. Super Micro Computer, Inc., No. CV-24-00731863-OOCP. The claim alleges that the Company violated Common Law (primary and secondary market misrepresentations) and the Ontario Securities Act, due to alleged misrepresentations and/or omissions in public statements regarding the Company’s financial results and its internal controls and procedures. A case management judge was assigned in December 2024, but no case conference has been scheduled and no timetable for subsequent procedural steps has been set. The matter is too preliminary to form a judgment as to whether the likelihood of an adverse outcome is probable and the Company is unable to estimate the possible loss or range of loss, if any. In late 2024, the Company received subpoenas from the Department of Justice and the Securities and Exchange Commission seeking a variety of documents following the publication in a short seller report which was published in August 2024. The Company is cooperating with these document requests and no charges have been brought as of the date of this filing. Other legal proceedings and indemnifications In addition to the matters described above, from time to time, the Company has been involved in various legal proceedings, disputes, claims, and regulatory or governmental inquiries and investigations arising from the normal course of business activities. The resolution of any such matters have not had a material impact on the Company’s condensed consolidated financial condition, results of operations or liquidity as of September 30, 2024 and any prior periods. The Company has entered into indemnification agreements with its current and former directors and executive officers. Under these agreements, the Company has agreed to indemnify such individuals to the fullest extent permitted by law against liabilities that arise by reason of their status as directors or officers and to advance expenses incurred by such individuals in connection with related legal proceedings. It is not possible to determine the maximum potential amount of payments the Company could be required to make under these agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each claim. However, the Company maintains directors and officers liability insurance coverage to reduce its exposure to such obligations. Purchase Commitments - The Company has agreements to purchase inventory and non-inventory items primarily through the next 12 months. As of September 30, 2024, these remaining non-cancelable commitments were $4.9 billion, including $136.7 million for related parties. The Company also reviews and assesses the need for expected loss liabilities on a quarterly basis for all products it does not expect to sell for but has committed purchases from suppliers. There were no loss liabilities recognized as of September 30, 2024 and $26.4 million of loss liabilities were recognized in Accrued liabilities in the condensed consolidated balance sheets from purchase commitments as of June 30, 2024. Lease Commitments - See Note 8, "Leases," for a discussion of the Company's operating lease commitments.
