#1SUPERMICR FISCAL Q3 2023 RESULTS May 2, 2023 POMICH SUPERMICR SUPERMICR SUPERMICR SUPER Better Faster Greener TM 2023 Supermicro#2DISCLOSURES Cautionary Statement Regarding Forward Looking Statements Statements contained in this presentation 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. Such forward looking statements may relate to, among other things, the fourth quarter of fiscal year 2023 and full year fiscal 2023 guidance, the ability to execute on the company strategy, the ability to achieve revenue targets, the ability to implement expansion plans, and TCO savings, fossil fuel reduction and trees saved through the Company's resource savings servers. 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) the global COVID-19 pandemic may continue to present significant uncertainties for parts of our business including our supply chain, our production operations and customer demand, (ii) our quarterly operating results may fluctuate, which could cause rapid declines in our stock price, (iii) 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 be less predictable, (iv) if we fail to meet publicly announced financial guidance or other expectations about our business, our stock could decline in value, (v) 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 (vi) adverse economic conditions may harm our business. Additional factors that could cause actual results to differ materially from those projected or suggested in any forward looking statements are contained 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, 2022, and Quarterly Reports on Form 10-Q filed thereafter. Use of Non-GAAP Financial Measures Each of non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating margins, and non-GAAP diluted net income per common share adds back and excludes various items that are discussed in the accompanying reconciliation table herein. Management presents non-GAAP financial measures because it considers them to be important supplemental measures of performance. Management uses the non-GAAP financial measures for planning purposes, including analysis of the Company's performance against prior periods, the preparation of operating budgets and to determine appropriate levels of operating and capital investments. Management also believes that the non-GAAP financial measures provide additional insight for analysts and investors in evaluating the Company's financial and operational performance. However, these non-GAAP financial measures have limitations as an analytical tool and are not intended to be an alternative to financial measures prepared in accordance with GAAP. A reconciliation from GAAP gross margin to non-GAAP gross margin, from GAAP operating expenses to non-GAAP operating expenses, from GAAP operating margins to non-GAAP operating margins, from GAAP diluted net income per common share to non-GAAP net income and diluted net income per common share, and various other non-GAAP financial measures are included in the tables at the back of this presentation. 2 Better Faster Greener ™ 2023 Supermicro SUPERMICR#3CEO TAKEAWAYS Q3 FY23 Revenue • Q3 FY23 revenue: $1.28B, -5% YoY and -29% QoQ Key new component shortages for next generation products delayed shipments • Record demand for Al related systems at rack scale • Officially launched Supermicro systems on the X13, H13, and H100 platform ● Expanded Al offerings with Liquid-Cooled Al Dev Platform wins, NAB product of the year Executing on Our Strategy · Total IT Solution Racks available for released CPU/GPU/DPU offerings using Building Block Architecture .
