Exhibit 99.1

Supermicro Announces Third Quarter Fiscal Year 2026 Financial Results

SAN JOSE, Calif. -- May 5, 2026 -- (BUSINESS WIRE) -- Super Micro Computer, Inc. (NASDAQ: SMCI) (“Supermicro” or the “Company”), a Total IT Solution Provider for AI, Cloud, Storage, and 5G/Edge, today announced unaudited financial results for its third quarter of fiscal year 2026 ended March 31, 2026.

Third Quarter Fiscal Year 2026 Highlights

•Net sales of $10.2 billion versus $12.7 billion in Q2'26 and $4.6 billion in Q3'25.

•Gross margin of 9.9% versus 6.3% in Q2'26 and 9.6% in Q3'25.

•Net income of $483 million versus $401 million in Q2'26 and $109 million in Q3'25.

•Diluted net income per common share of $0.72 versus $0.60 in Q2'26 and $0.17 in Q3'25.

•Non-GAAP gross margin of 10.1% versus 9.7% in Q3'25.

•Non-GAAP diluted net income per common share of $0.84 versus $0.31 in Q3'25.

•Cash flow used in operations for Q3'26 of $6.6 billion and capital expenditures and investments of $97 million.

“Supermicro's transformation into a total datacenter infrastructure provider is accelerating," said Charles Liang, Founder, President and CEO of Supermicro. "Our margin recovery and the rapid growth of our DCBBS business demonstrate that our business remains robust. With the addition of our new US manufacturing facilities in Silicon Valley, we are exceptionally well-positioned to meet the massive demand for various AI and enterprise verticals.”

As of March 31, 2026, total cash and cash equivalents was $1.3 billion and total bank debt and convertible notes were $8.8 billion.

Business Outlook

The Company expects net sales in the range of $11.0 billion and $12.5 billion for the fourth quarter of fiscal year 2026 ending June 30, 2026, GAAP net income per diluted share of $0.53 to $0.67 and non-GAAP net income per diluted share of $0.65 to $0.79. The Company’s projections for GAAP and non-GAAP net income per diluted share assume a tax rate of approximately 19.4% and 20.4%, respectively, and a fully diluted share count of 695 million shares for GAAP and fully diluted share count of 712 million shares for non-GAAP. The outlook for the fourth quarter of fiscal year 2026 GAAP net income per diluted share includes approximately $95 million in expected stock-based compensation, net of related tax effects of $30 million that are excluded from non-GAAP net income per diluted share.

For fiscal year 2026, the Company expects net sales in the range of $38.9 billion to $40.4 billion.

Conference Call and Webcast Information

Supermicro will present a live audio webcast of our conference call to review its third quarter of fiscal year 2026 financial results on Tuesday, May 5, 2026, at 5:00 p.m. ET / 2:00 p.m. PT. The webcast will be available at https://ir.supermicro.com.

A replay of the webcast will be available shortly after the call at the same website and will remain accessible for one year.

Forward Looking Statements and Other Disclosures

Statements contained in this press release that are not historical fact may be forward looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements can be identified by the use of forward-looking terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “may,” "plan,” “seek,” “should,” “will,” “would” “optimistic” or similar expressions and the negatives of those terms. Such forward looking statements may include statements regarding, among other things, guidance for the fourth quarter of fiscal year 2026 and updated full year fiscal 2026 guidance, expectations related to strong customer engagements and that additional customer commitments will be secured in the upcoming quarters of fiscal year 2026, our efforts to strengthen our operational and financial execution, our focus on capturing the next wave of AI and IT infrastructure demand, meeting the Company's long-term targets and capitalizing on the growing market opportunity in the long-term, and our progressing leadership in DCBBS and AI technology. Such forward looking statements do not constitute guarantees of future performance and are subject to a variety of risks and uncertainties that could cause our actual results to differ materially from those anticipated, including: (i) our quarterly operating results may fluctuate, (ii) as we increasingly target larger customers and larger sales opportunities, our customer base may become more concentrated, our cost of sales may increase, our margins may be lower and our sales may become less predictable for a variety of reasons, many of which are not in our control, (iii) the average sales prices for our server solutions could decline if customers do not continue to purchase our latest generation products or additional components, and (iv) adverse economic conditions could affect our business, including, but not limited to, increased tariffs. In addition, as the Company has disclosed, the Board is conducting an independent review of certain transactions in connection with export-control issues. The outcome of that investigation could affect our forecasts, these preliminary results and prior period results. Certain prior period amounts have been reclassified to conform to the current period presentation. Additional factors that could cause actual results to differ materially from those projected or suggested in any forward looking statements are detailed in our filings with the Securities and Exchange Commission, including those factors discussed under the caption "Risk Factors" in such filings, particularly in our Annual Report on Form 10-K for our fiscal year ended June 30, 2025 and any subsequent Quarterly Report on Form 10-Q.

Financial Information Is Preliminary and May Be Subject to Change

The unaudited interim financial information presented in this press release is preliminary. The final financial results reported for this period may also differ from the results reported in this release.

The financial results presented reflect the Company's preliminary estimated unaudited financial results, based upon information available to the Company as of the date of this press release. The Company has provided preliminary estimates of financial results primarily because its financial closing procedures for the quarter ended March 31, 2026 are not yet complete. The data are not a comprehensive statement of the Company's results for such periods, and the actual results may differ materially from these preliminary estimated data. The Company's actual results remain subject to the completion of management’s and its audit committee’s review and other financial closing processes as well as the completion and preparation of its financial data for such periods. The Company's independent registered public accounting firm has not audited, reviewed, compiled or performed any procedures with respect to such preliminary data. During the course of the preparation of the Company's financial statements and related notes and the completion of the review for such periods, additional adjustments to the preliminary estimated financial information presented here may be identified, and its final results

for these periods may vary from these preliminary estimates. This preliminary estimated data should not be considered a substitute for the financial statements to be prepared in accordance with accounting principles generally accepted in the United States and to be filed with the Securities and Exchange Commission once available.

RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES

(in thousands, except per share amounts)

(unaudited)

Use of Non-GAAP Financial Measures

To supplement its condensed consolidated financial results presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), the Company uses non-GAAP measures that are adjusted for certain items from the most directly comparable GAAP measures. The specific non-GAAP measures presented below are: gross profit, gross margin; operating expenses; net income; net income per common share; diluted net income; diluted net income per common share, adjusted earnings before interest, taxes, depreciation, and amortization, (“Adjusted EBITDA”); and effective tax rate. Management believes these non-GAAP measures provide useful information to investors by offering a consistent basis for comparing the Company's performance across periods, excluding items that are not reflective of our core operating results. These non-GAAP measures are not prepared in accordance with GAAP or intended to be a replacement for GAAP financial data; and therefore, should be reviewed together with the GAAP measures and are not intended to serve as a substitute for results under GAAP, and may be different from non-GAAP measures used by other companies.

We exclude the following adjustments from our non-GAAP financial measures:

Non-GAAP Adjustments

•Stock-based compensation: Stock-based compensation relates primarily to our equity incentive awards. Stock-based compensation is a non-cash expense that is dependent on market forces that are difficult to predict. We believe that this adjustment for stock-based compensation provides investors with a basis to measure the company's core performance, including compared with the performance of other companies, without the period-to-period variability created by stock-based compensation.

•Adjusted EBITDA adjustments: When calculating Adjusted EBITDA, in addition to the adjustments described above, we exclude the impact of Interest expense, Income tax (provision) benefit, and Depreciation and amortization during the period.

Pursuant to the requirements of SEC Regulation G, please see the tables below for the reconciliations of GAAP to Non-GAAP measures. These should be read together with the preceding financial statements prepared in accordance with GAAP.
