1 Important Information Forward-Looking Statements This presentation contains forward-looking statements that are subject to risks and uncertainties. All statements other than statements of historical fact included in this presentation are forward-looking statements. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as "anticipate," "estimate," "expect," "project," "plan,“ "intend," "believe," “outlook” and other words of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events, but not all forward-looking statements contain these identifying words. These forward-looking statements are based on assumptions that the Boot Barn Holdings, Inc.’s (the “Company,” “Boot Barn,” “BOOT,” “we,” “us,” and “our,”) management has made in light of their industry experience and on their perceptions of historical trends, current conditions, expected future developments and other factors that they believe are appropriate under the circumstances. As you consider this presentation, you should understand that these statements are not guarantees of performance or results. They involve risks, uncertainties (some of which are beyond the Company’s control) and assumptions. These risks, uncertainties and assumptions include, but are not limited to, the following: decreases in consumer spending due to declines in consumer confidence, local economic conditions or changes in consumer preferences; the impact that import tariffs and other trade restrictions imposed by the U.S., China or other countries have had, and may continue to have, on our product costs and changes to U.S. or other countries’ trade policies and tariff and import/export regulations, including, without limitation, uncertainty with respect to the U.S. – China tariff deal; the Company’s ability to effectively execute on its growth strategy; and the Company’s failure to maintain and enhance its strong brand image, to compete effectively, to maintain good relationships with its key suppliers, and to improve and expand its exclusive product offerings. The Company discusses the foregoing risks and other risks in greater detail under the heading “Risk factors” in the periodic reports filed by the Company with the Securities and Exchange Commission. Although the Company believes that these forward-looking statements are based on reasonable assumptions, you should be aware that many factors could affect the Company’s actual financial results and cause them to differ materially from those anticipated in the forward-looking statements. Because of these factors, the Company cautions that you should not place undue reliance on any of these forward-looking statements. New risks and uncertainties arise from time to time, and it is impossible for the Company to predict those events or how they may affect the Company. Further, any forward-looking statement speaks only as of the date on which it is made. Except as required by law, the Company does not intend to update or revise the forward-looking statements in this presentation after the date of this presentation. Industry and Market Information Statements in this presentation concerning our industry and the markets in which we operate, including our general expectations and competitive position, business opportunity and market size, growth and share, are based on information from independent industry organizations and other third-party sources, data from our internal research and management estimates. Management estimates are derived from publicly available information and the information and data referred to above and are based on assumptions and calculations made by us based upon our interpretation of such information and data. The information and data referred to above are imprecise and may prove to be inaccurate because the information cannot always be verified with complete certainty due to the limitations on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties. As a result, please be aware that the data and statistical information in this presentation may differ from information provided by our competitors or from information found in current or future studies conducted by market research institutes, consultancy firms or independent sources. Recent Developments Our business and opportunities for growth depend on consumer discretionary spending, and as such, our results are particularly sensitive to economic conditions and consumer confidence. Inflation, changes to U.S. or other countries’ trade policies and tariff and import/export regulations, and other challenges affecting the global economy could impact our operations and will depend on future developments, which are uncertain. These and other effects make it more challenging for us to estimate the future performance of our business, particularly over the near-to-medium term. For further discussion of the uncertainties and business risks affecting the Company, see the sections captioned “Risk factors” in our periodic reports filed with the Securities and Exchange Commission.

Fiscal 2026 guidance assumes increased tariffs result in price increases this summer, leading to softer consumer demand. The difference between the low and high-end scenarios reflect different degrees of impact on consumer demand. Fiscal 2026 guidance assumes a merchandise margin decline in the second half of the fiscal year due to unmitigated tariff costs. The difference between the low and high-end scenarios reflect different degrees of impact on margin degradation. Fiscal 2026 contemplates a 30% tariff on China, 10% global tariff rate, and 0% tariff on Mexico (USMCA compliant).

16 Tariff Mitigation Strategy • Given BOOT’s lower inventory turns (~2x per year) plus accelerated receipts ahead of tariffs, the impact of recent tariffs is expected to largely be in the second half of Fiscal 2026. • Third-party inventory – we have been notified of cost increases on products that we source from vendors effective this summer. BOOT expects to increase retail prices on the impacted products in order to maintain merchandise margin rates. Pricing from vendors is expected to increase mid-single-digits. • Exclusive brands product – we are working to mitigate the impact of the increased tariffs: • Factories are reducing costs to BOOT in order to reduce the tariff impact. • Factories are re-sourcing production to countries with lower tariffs. • BOOT is cancelling product orders with post-tariff low merchandise margins. • BOOT is evaluating each item individually to determine if pricing will remain unchanged, resulting in a lower merchandise margin rate, or be increased in order to preserve some or all merchandise margin rate.

17 Estimated Exclusive Brands Tariff Impact The following information provides estimates and assumptions to help quantify the potential impact of tariffs on the Company’s exclusive brands business. Fiscal 2026 guidance contemplates a 30% tariff on China, 10% global tariff rate, and 0% tariff on Mexico (USMCA compliant). $8 $154 $232 $386 $1,073 FY26 Estimated Tariff Impact on Exclusive Brands (EB) $M FY26 Total Company Consolidated Merchandise COGS FY26 EB Portion of Merchandise COGS FY26 EB COGS of Inventory Purchased Pre-Tariffs FY26 EB COGS of Inventory Purchased Post-Tariffs COGS related to exclusive brands (EB) is estimated to be ~36% of total merchandise COGS. ~60% of FY26 exclusive brand sales are estimated to be from merchandise purchased pre-tariffs. ~40% of FY26 exclusive brand sales are estimated to be from merchandise purchased post-tariffs. Tariff Impact to FY26 Exclusive Brands Merchandise COGS Based on factories absorbing costs, re-sourcing production, order cancellations, and inventory acceleration in advance of tariffs, we estimate that the impact of recent tariffs will result in $8 million in additional costs during Fiscal 2026.

18 Share Repurchase Program The Company’s Board of Directors has authorized the Company to repurchase up to $200 million of its common stock. We plan to execute a quarter of the total authorization this fiscal year, with the spend roughly consistent by quarter and this has been factored into our guidance.
