This presentation shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction. The information in this presentation is current only as of the date of this presentation and may have changed. We undertake no obligation to update any such information in light of new information, future events or otherwise. Forward-Looking Statements Certain statements made in this presentation are "forward looking statements" within the meaning of the "safe harbor" provisions of the United States Private Securities Litigation Reform Act of 1995. When used in this press release, the words "estimates," "projected," "expects," "anticipates," "forecasts," "plans," "intends," "believes," "seeks," "may," "will," "would," "should," "future," "propose," "target," "goal," "objective," "outlook" and variations of these words or similar expressions (or the negative versions of such words or expressions) are intended to identify forward-looking statements. These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside Holley's control that could cause actual results or outcomes to differ materially from those discussed in the forward-looking statements. Any such forward-looking statements are made pursuant to the safe harbor provisions available under applicable securities laws and speak only as of the date of this presentation.

Important factors, among others, that may affect actual results or outcomes include the inability to recognize the anticipated benefits of the recently completed business combination; costs related to the recently completed business combination; Holley's ability to manage growth; Holley's ability to execute its business plan and meet its projections; potential litigation involving Holley; changes in applicable laws or regulations; the possibility that Holley may be adversely affected by other economic, business, and competitive factors; the impact of the continuing COVID-19 pandemic on Holley's business as well as those factors described in the "Risk Factors" section of our filings with the SEC. Non-GAAP Financial Measures This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles ("GAAP") including, but not limited to, Pro Forma Adjusted EBITDA, EBITDA, Pro Forma Free Cash Flow, Pro Forma Net Sales, Gross Profit, Pro Forma Net Leverage 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 Holley'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 Holley's presentation of these measures may not be comparable to similarly-titled measures used by other companies. Holley believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Holley's financial condition and results of operations. Holley believes that the use of these non- GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing Holley's financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. The Appendix to this Presentation provides all non-GAAP measures and reconciliations of these non-GAAP measures to the corresponding most closely related GAAP measures. Industry and Market Data In this Presentation, the Company relies on and refers to certain information and statistics obtained from third-party sources which it believes to be reliable. Holley has not independently verified the accuracy or completeness of any such third-party information. Holley 1
