Forward-Looking Statements and Non-GAAP Financials

This Presentation and the accompanying oral presentation include "forward‐looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, regarding Ichor Holdings, Ltd. and its subsidiaries ("Ichor" or the "Company"), its financial condition, its results of operations and the potential offering that reflect the Company's current views and information currently available. This information is, where applicable, based on estimates, assumptions and analysis that Ichor believes, as of the date hereof, provides a reasonable basis for the information contained herein. Forward‐looking statements can generally be identified by the use of forward‐looking words such as "may", "will", "would", could", "expect", "intend", "plan", "aim", "estimate", "target", "anticipate", "believe", "continue", "objectives", "outlook", "guidance" or other similar words, and include statements regarding Ichor's plans, strategies, initiatives, objectives, targets and future operating or financial performance. These forward‐looking statements involve known and unknown risks, uncertainties and other factors (including those set forth under "Risk Factors" in Ichor's prospectus), many of which are outside the control of Ichor and its representatives. Actual results, performance or achievements may differ materially and potentially adversely from any projections and forward‐looking statements and the assumptions on which those forward-looking statements are based. There can be no assurance that the information contained in this Presentation is reflective of future performance to any degree, and readers are cautioned not to place undue reliance on forward‐looking statements as a predictor of future performance. All information in this Presentation speaks only as of the date hereof unless otherwise specified. Ichor undertakes no duty to update or revise the information contained herein, publicly or otherwise, whether as a result of new information, future events or otherwise. Forecasts and estimates regarding the Ichor's industry and end-markets are based on sources we believe to be reliable; however, there can be no assurance these forecasts and estimates will prove accurate in whole or in part.

This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles ("GAAP"), including, but not limited to, adjusted net income from continuing operations and certain ratios and other metrics derived therefrom. These non‐GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing Ichor's financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that Ichor's presentation of these measures may not be comparable to similarly‐titled measures used by other companies. Non-GAAP reconciliations are contained at the end of this document and in Ichor's SEC filings.

This Presentation also contains estimates and other statistical data made by independent parties relating to market size and growth and other industry data. These data involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. The Company has not independently verified the statistical and other industry data generated by independent parties and contained in this presentation and, accordingly, it cannot guarantee their accuracy or completeness. In addition, projections, assumptions and estimates of its future performance and the future performance of the markets in which it competes are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause results or outcomes to differ materially from those expressed in the estimates made by the independent parties.

Investment Highlights

• Strong Track Record of Revenue Growth Outperforming the Overall Industry: We delivered annual revenue growth of 24% (CAGR) from 2015 to 2022, outperforming annual WFE (wafer fab equipment) growth of 17% over the same period; multiple strategies in place to continue delivering above-industry revenue growth(1)
• Multiple Technology Transitions are Driving Growth in Ichor's Served Markets: WFE intensity continues to trend upward as the industry is driving aggressively toward advanced nodes (e.g., gate-all-around, EUV, 3D DRAM) and trailing node applications continue to expand (e.g., advanced packaging, non-traditional applications such as SiC and non-semi)
• New Technologies and Processes Require the Increasing Deployment of Growth Applications within WFE: Key technology inflections driving demand across multiple emerging growth segments within etch, deposition and lithography that have significant fluid delivery requirements – creating strong growth opportunity for Ichor's broad portfolio of subsystems and components
• Increasing Investment in Proprietary Products to Drive Gross Margin Expansion: We are engaged with multiple customers who are evaluating adoption of our next-generation gas panel and components that contain significantly higher proprietary Ichor content, which is a key aspect of our strategies to deliver gross margin expansion
• Strong Track Record of Growing Earnings Faster than Revenues as Demand Ramps: Our net profitability has historically increased at roughly 2x the rate of revenue growth during a WFE industry upturn
