This Current Report on Form 8-K will not be deemed an admission as to the materiality of any information contained in this Item 7.01, including Exhibit 99.1.

Certain statements in this Current Report on Form 8-K are forward-looking statements. Forward-looking statements generally relate to future events including future financial or operating performance of Authentic Brands LLC (the “Company”) or SilverBox Engaged Merger Corp I (“SBEA”). Forward-looking statements generally relate to future events or SBEA’s or the Company’s future financial or operating performance. For example, projections of future revenue and other metrics are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may”, “should”, “expect”, “intend”, “will”, “estimate”, “anticipate”, “believe”, “predict”, “potential” or “continue”, or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are subject to risks, uncertainties, and other factors that could cause actual results to differ materially from those expressed or implied by such forward-looking statements.

These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by SBEA and its management, and the Company and its management, as the case may be, are inherently uncertain and are inherently subject to risks, variability and contingencies, many of which are beyond the Company’s control. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (1) SBEA’s ability to complete the business combination; (2) the outcome of any legal proceedings that may be instituted against SBEA, the combined company or others following the announcement of the business combination and any definitive agreements with respect thereto; (3) the inability to complete the business combination due to the failure to obtain approval of the stockholders of SBEA, to obtain financing to complete the business combination or to satisfy other conditions to closing; (4) changes to the proposed structure of the business combination that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the business combination; (5) the ability to meet stock exchange listing standards following the consummation of the business combination; (6) the risk that the business combination disrupts current plans and operations of the Company as a result of the announcement and consummation of the business combination; (7) the ability to recognize the anticipated benefits of the business combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain key relationships and retain its management and key employees; (8) costs related to the business combination; (9) changes in applicable laws or regulations; (10) the possibility that the Company or the combined company may be adversely affected by other economic, business, and/or competitive factors; (11) the Company’s estimates of expenses and profitability; (12) the failure to realize anticipated pro forma results or projections and underlying assumptions, including with respect to estimated stockholder redemptions, purchase price and other adjustments; and (13) other risks and uncertainties set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in SBEA’s final prospectus relating to its initial public offering dated February 25, 2021, in the registration statement on Form S-4 (the “Form S-4”) relating to the business combination filed with the Securities and Exchange Commission (the “SEC”), and in subsequent filings with the SEC, including the final prospectus/proxy statement relating to the business combination. There may be additional risks that neither SBEA nor the Company presently know or that SBEA and the Company currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements.

Nothing in this Current Report on Form 8-K should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. Neither SBEA nor the Company undertakes any duty to update these forward-looking statements or to inform the recipient of any matters of which any of them becomes aware of which may affect any matter referred to in this Current Report on Form 8-K.

DISCLAIMER (CONT’D) Non-GAAP Financial Measures This Presentation includes projections of certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, EBITDA, EBITDA Margin, Adjusted EBITDA, Adjusted EBITDA Margin, Gross Profit, Average Unit Volume (“AUV”) 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 the Company’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 the Company’s presentation of these measures may not be comparable to similarly-titled measures used by other companies. The Company believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and results of operations. The Company 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 the Company’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. Use of Projections This Presentation contains financial forecasts with respect to the Company’s projected financial results, including Revenue and Adjusted EBITDA, for the Company’s fiscal years 2021 through 2023. The Company’s independent auditors have not audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this Presentation. These projections should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of the Company or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this Presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. Industry and Market Data This presentation also contains estimates and other statistical data made by independent parties and by the Company relating to market size and growth and other data about the Company’s industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions, and estimates of the future performance of the markets in which the Company operates are necessarily subject to a high degree of uncertainty and risk. Any trademarks, servicemarks, trade names and copyrights of the Company and other companies contained in this Presentation are the property of their respective owners.

Black Rifle Coffee Company SUMMARY KEY RISKS 53 Risks Related to the Company’s Business • The Company’s success is dependent upon evolving consumer preferences and tastes, and shifts in consumer spending, lack of interest in new products, or changes in brand perception can negatively affect consumer demand for the Company’s products. • The Company’s success is dependent upon certain financial conditions and any number of factors outside the Company’s control could negatively impact the Company’s results of operations. These factors include, but are not limited to, fluctuations in the cost and availability of real estate, labor, raw materials, equipment, transportation, shipping, pricing pressure, changes in consumer preferences, natural or man-made disasters, pandemics, social unrest, war, political instability, adverse litigation outcomes, or changes in consumer discretionary spending. Money available for consumer discretionary spending may be affected by job losses, inflation, higher taxes, changes in federal economic policy, and other macroeconomic or political events. • The Company may not always be successful in its marketing efforts. Failed marketing campaigns can incur costs without the benefit of attracting new customers or realizing higher revenue. Failure to attract new customers or retain existing customers, or failure to do so in a cost-effective manner, may result in an inability to increase sales and harm to our business. • The Company relies heavily on social media to advertise and engage with the Company’s customers. Using social media platforms for advertisements carries a number of associated risks, including dependence on the third party platforms to maintain their platforms in a manner that benefit the Company’s marketing strategies. Additionally, the Company is subject to the laws and regulations that govern the use of these platforms and is subject to the risks of improper use. • Launching and promoting new products is expensive and time-consuming and the Company may not always succeed in bringing new products to market. • The Company may not be able to compete successfully with other producers and retailers of coffee. Some of the Company’s competitors are longer-established, have greater brand recognition, and have substantially greater financial, technological, roasting, sale, distribution, and other resources. • The Company has a limited operating history and therefore it may be difficult to evaluate future risks and challenges. • The Company is heavily dependent on its direct to consumer channel for success, and this channel relies on third party logistics to succeed. Decrease in success of the direct to consumer channel or any failure or impediment on behalf of third party logistics providers could harm the Company. • The Company relies on its wholesale business partners to effectively distribute its products. Failure on behalf of its third party partners to effectively manage or distribute the Company’s products, such as by effectively displaying or presenting our products, grow or promote the brand, provide satisfactory consumer experiences, or fulfill their contractual obligations could harm the Company. Failure by the Company to maintain and develop these business relationships could harm our business. • The Company relies on co-manufactures to supply some of its products, and a loss of one or more of these partners, or failure of these partners to fulfill their contractual obligations, could harm the Company. • The Company’s growth strategy depends in part on opening new retail coffee shops. The success of new shops is dependent on a variety of factors, including, but not limited to, consumer preferences, availability of retail space, leasing conditions, construction and equipment costs, and local permitting, licensing, zoning, and other requirements and regulations. There is no guarantee that new retail shops will be successful, and new retail shops could entail high costs without realized profits. • The Company has experienced rapid growth and increased demand for its products. Failure to properly manage this growth and manage the Company’s relationships with its various business partners, or failure to accurately forecast our results of operations and growth rate, could harm the Company’s operating results. • The Company’s brand and reputation are critical to its success, and any publicity, regardless of accuracy, that portrays the Company negatively could adversely impact operating results. Negative publicity may arise for various reasons, whether true or not, including, but not limited to, complaints about product quality, safety, or sanitation; company policies; adverse litigation; employment practices; employee actions; actions taken by customers; social media posts; and actions taken by third party business partners. For instance, the Company has recently received negative publicity arising out of the presence of the Company's logos on apparel worn at politically charged events and there is no assurance that any such negative publicity will not occur again in the future which could harm our business. • The Company plans to expand into new domestic and international markets, and failure to successfully integrate into these new markets could affect the Company’s profitability. • The Company is subject to the risks associated with leasing space subject to long-term non-cancelable leases and with respect to real property that the Company itself owns. • The Company relies in part on the success of its franchise partners, over whom the Company has limited control with respect to their operations. Failure on behalf of the Company’s franchise partners to successfully manage their franchises or effectively represent the Company and its brand could harm the Company’s business results. • The Company relies on a number of third parties in the supply chain of coffee, store supplies, or merchandise to produce or deliver its products, and failure by these third parties to efficiently operate could adversely impact the Company. • The Company is heavily dependent on the market for high-quality Arabica coffee beans and other commodities, and changes in these markets that increase costs or reduce supply, such as through adverse weather, natural disasters, crop disease, political unrest, and other economic conditions, could harm the Company’s operating results. • The Company relies on its employees to provide a high-quality customer experience, and any failure on behalf of the Company to cater to the consumer experience could harm the brand.

Black Rifle Coffee Company SUMMARY KEY RISKS (CONT’D) 54 Risks Related to the Company’s Business (Cont’d) • The Company's results of operations are subject to seasonal and quarterly variations, which could cause the price of our common stock to decline. • The Company must maintain adequate operational and financial resources, especially if the Company continues to grow, in order to maintain its current market performance. • The Company depends on cash generated from our operations to support our growth, and we may need to raise additional capital, which may not be available on acceptable terms. • The Company depends heavily on information technology and its ability to process data in order to sell goods and services. Failure to protect against software or hardware vulnerabilities, as well as disruption, for any reason, to these information technology systems, could result in operating losses, privacy and security breaches, loss of customers, liability, damage our customer and business partner relationships, and other significant reputational, financial, legal, and operational consequences. • Pandemics or disease outbreaks, such as the COVID-19 pandemic, could adversely affect the Company’s business by disrupting supply chains, negatively impacting consumer preferences and spending, and reducing foot traffic to the Company’s retail coffee shops and wholesale business partners. Risks Related to the Company’s Brand • The Company promotes itself as a supportive member of the veteran and military community, and actively participates in this community through donations, hiring commitments, and other events. Failure by the Company to maintain this strong branding could negatively impact the Company’s business. Additionally, any other factors which may negatively impact perception of the brand, including factors listed elsewhere in this summary, may harm the Company. • The Company holds various forms of intellectual property, including trademarks, trade names, and service marks. The Company’s success is partially dependent upon its ability to build brand recognition using these marks and to protect its intellectual property from infringement and misuse. • The Company is subject to a variety of food safety regulations, and failure to adequately maintain food safety or quality, or reports that the Company had safety issues or failed to implement proper safety measures, whether true or not, could result in loss of customers, regulatory warnings, food recalls, and other adverse outcomes that could impact the Company’s profitability. • The Company possesses personal, financial, and other confidential data from customers and employees, and if that data is compromised or lost, even through the actions of third parties, the Company could be subject to litigation, liability, and reputational damage. Risks Related to People and Culture • The Company’s success relies heavily on its ability to hire and retain qualified employees, and changes in the availability and the cost of labor could harm its operating results. • The Company depends on its executive officers and other key employees, and the loss of one or more of these individuals, or the inability to attract and retain suitable replacements, could harm the Company’s business. • If the Company’s employees were to unionize, and if collective bargaining agreement terms were significantly different than current compensation agreements, the Company’s operating results could suffer. Risks Related to Regulation and Litigation • The Company is subject to numerous statutory, regulatory, and other legal requirements regarding accounting practices. Failure to comply with these requirements, or changes in these requirements, could negatively impact the Company’s operating and financial results. • The Company is subject to taxes by the U.S. federal, various state, and various local tax authorities. Changes in the Company’s tax liability could negatively impact the Company’s operating and financial results. • The Company and its vendors collect, store, process, and use personal and payment information and other customer data, which subjects us to a variety of laws, regulations, and industry standards relating to data processing, protection, privacy, and security. The actual or perceived failure by the Company, its customers, or its vendors to comply with such laws, regulations, or industry standards may harm the Company’s results of operations. • The Company is subject to laws and regulations from the FDA and FTC governing food and beverage labeling and misleading advertisements. If the Company mislabels its products or advertises in a way that is untruthful or misleading, the Company may be subject to liability. • The Company is subject to laws and regulations that govern the display and provision of nutritional information of its products. Failure to comply with these requirements or adverse consumer perceptions based on health information could negatively impact the Company’s operating results. • The Company and its franchise partners are subject to various other federal, state, and local laws and regulations not listed above. These laws include the FLSA, FMSA, and ADA, as well as laws relating to food and beverage safety, zoning, licenses and permits, employment, and franchising, among others. Failure to comply with applicable laws and regulations could result in liability for the Company. • Beverage and restaurant companies have been the target of class action lawsuits and other proceedings. The Company, as a participant in this market, is subject to those same risks, whether liable or not. Lawsuits and proceedings are costly, divert management attention, and could result in negative public perception, regardless of the validity of claims, and therefore implementation of any proceedings could harm the Company.

Black Rifle Coffee Company SUMMARY KEY RISKS (CONT’D) 55 Risks Related to Public Company • The Company’s management team has limited experience managing a public company. • It is possible that the Company’s internal control over financial reporting is not effective because it cannot detect or prevent material errors at a reasonable level of assurance. The Company’s past or future financial statements may not be accurate and it may not be able to timely report its financial condition or results of operations, which may adversely affect investor confidence in the Company and the price of the common stock. • The Company will incur increased costs as a result of operating as a public company, and its management will be required to devote substantial time to new compliance initiatives and corporate governance practices. • Upon closing of the Business Combination, the public company will be a “controlled company” within the meaning of the applicable exchange rules and, as a result, will qualify for exemptions from certain corporate governance requirements. The stockholders of the public company will not have the same protections afforded to stockholders of companies that are subject to such requirements. • You may not have the same benefits as an investor in an underwritten public offering. Risks Related to Business Combination • The benefits of the proposed Business Combination may not be realized to the extent currently anticipated by the Company or SilverBox, or at all. The ability to recognize any such benefits may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees. • The costs related to the Business Combination could be significantly higher than currently anticipated. • The consummation of the Business Combination is expected to be subject to a number of conditions and, if those conditions are not satisfied or waived, any definitive agreement relating to the Combination Agreement may be terminated in accordance with its terms and the Business Combination may not be completed. • SilverBox’s directors and officers may have interests in the Business Combination different from the interests of SilverBox, the Company or their respective stockholders. • The Business Combination will result in changes to the board of directors of the Company that may affect the strategy of the combined company. • SilverBox’s sponsor has agreed to vote in favor of the Business Combination, regardless of how SilverBox’s public stockholders vote. As a result, approximately 20.0% of SilverBox’s voting securities outstanding, representing the SilverBox voting securities held by SilverBox’s sponsor, will be contractually obligated to vote in favor of the Business Combination. • The ability of SilverBox’s stockholders to exercise redemption rights with respect to a large number of outstanding SilverBox’s Class A common stock could increase the probability that the business combination would not occur. • SilverBox’s board of directors did not obtain a third-party valuation or fairness opinion in determining whether or not to proceed with the Business Combination and, as a result, the terms may not be fair from a financial point of view to the Public Stockholders.
