Forward-Looking Statements Certain statements in this Presentation may be considered forward-looking statements. Forward-looking statements generally relate to future events or MDH’s or the Company’s future financial or operating performance. For example, projections of future Adjusted EBITDA 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 which 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 MDH and its management, and the Company and its management, as the case may be, are inherently uncertain. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of negotiations and any subsequent definitive agreements with respect to the Business Combination; (2) the outcome of any legal proceedings that may be instituted against MDH, 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 shareholders of MDH, 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 of the Company 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 relationships with customers and suppliers 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; and (12) other risks and uncertainties set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in MDH’s periodic filings with the SEC, including MDH’s final prospectus relating to its initial public offering dated February 1, 2021 and in the Form S-4 (as defined below). Nothing in this Presentation 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 MDH nor the Company undertakes any duty to update these forward-looking statements. 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 2024. 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. All projections and estimates included in this presentation are approximations. This includes annualized information where the results from a month are converted to a full year even though such monthly results may not be indicative of the results the Company would achieve for a full year. Disclaimer

Disclaimer (continued) Financial Information; Non-GAAP Financial Measures Certain of the financial information and data contained in this Presentation is unaudited and does not conform to Regulation S-X. In addition, this Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, Net Premium, EBITDA, Adjusted EBITDA, Adjusted Gross Profit 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. Please refer to footnotes where presented on each page of this Presentation or to page 30 of this Presentation for a reconciliation of these measures to what the Company believes are the most directly comparable measure evaluated in accordance with GAAP. This Presentation also includes certain projections of non-GAAP financial measures. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward-looking non-GAAP financial measures is included. Industry and Market Data In this Presentation, MDH and the Company rely on and refer to certain information and statistics obtained from third-party sources which they believe to be reliable. Neither MDH nor the Company has independently verified the accuracy or completeness of any such third-party information.

32 Summary of Risks Certain Risks Related to OP Group Holdings, LLC • You should carefully consider all the following risk factors, together with all of the other publically available information, including the financial information, before deciding how to invest. • The value of your investment following the completion of the Business Combination will be subject to significant risks affecting, among other things, PubCo and OP Group’s business, financial condition and results of operations. If any of the events described below occur, PubCo’s post-Business Combination business and financial results of PubCo and its subsidiaries could be adversely affected in material respects. This could result in a decline, which may be significant, in the trading price of PubCo’s securities and you therefore may lose all or part of your investment. The risk factors described below are not necessarily exhaustive and you are encouraged to perform your own investigation with respect to the businesses of MDH and OP Group. • Unless the context otherwise requires, all references in this section to the “Company,” “we,” “us” or “our” refer to the business of OP Group prior to the Closing, which will be the business of PubCo and its subsidiaries following the Closing. • The list below is qualified in its entirety by disclosures contained in future filings by the Company, or by third parties (including MDH Acquisition Corp.) with respect to the Company, with the United States Securities and Exchange Commission (“SEC”). These risks speak only as of the date of this presentation and we make no commitment to update such disclosure. The risks highlighted in future filings with the SEC may differ significantly from and will be more extensive than those presented below. . Risks related to the Business Combination, including that: • Sponsor has agreed to vote in favor of the Business Combination Proposal described in this proxy statement/prospectus, regardless of how the Public Stockholders vote. • MDH and Op Group’s directors have interests that are different from, or in addition to (and which may conflict with), the interests of the Public Stockholders. • The announcement of the proposed Business Combination could disrupt OP Group’s business. • MDH has not obtained a third-party opinion in determining whether to pursue the Business Combination. • The unaudited pro forma financial information may not be representative of PubCo’s results if the Business Combination is completed. • During the pendency of the Business Combination, MDH will not be able to enter into a business combination with another party because of restrictions in the Business Combination Agreement. Furthermore, certain provisions of the Business Combination Agreement will discourage third parties from submitting alternative takeover proposals, including proposals that may be superior to the arrangements contemplated by the Business Combination Agreement. • The Proposed PubCo Charter will not limit the ability of Sponsor or its affiliates to compete with us. Risks related to the redemption, including that: • The ability of the Public Stockholders to exercise Redemption Rights with respect to Public Shares may prevent MDH from completing the Business Combination or optimizing its capital structure. • If a Public Stockholder fails to receive notice of MDH’s offer to redeem Public Shares in connection with the Business Combination, or fails to comply with the procedures for tendering its Public Shares, such shares may not be redeemed. • There is no guarantee that a Public Stockholder’s decision whether to redeem its Public Shares will put the Public Stockholder in a better future economic position. Risks if the Business Combination is not consummated, including that: • If the conditions to the Business Combination Agreement are not met, the Business Combination may not occur. • If MDH is unable to complete an initial business combination within 24 months from the closing of the IPO, unless otherwise extended, MDH will cease all operations except for the purpose of winding up and it would redeem the Public Shares and liquidate. • You have limited rights or interests in funds in the Trust Account. To liquidate your investment, therefore, you may be forced to sell your Public Shares or MDH Public Warrants, potentially at a loss.

33 Summary of Risks (continued) Risks related to our organizational structure after the Business Combination, including that: • PubCo will be a holding company and its only material asset after completion of the Business Combination will be its interest in its subsidiaries. • Entities affiliated with CF OMS and Blocker Owner will beneficially own, in the aggregate, approximately 73.8% of outstanding PubCo Common Stock upon completion of the Business Combination, and these stockholders may have strategic interests that differ from PubCo’s interests and from those of PubCo’s other stockholders. Risks related to OP Group’s business and industry, including that: • OP Group has identified material weaknesses in its internal control over financial reporting and may identify additional material weaknesses in the future or fail to maintain an effective system of internal control over financial reporting. • OP Group’s success and its ability to grow its business depend on retaining and expanding its customer base. • OP Group may be unable to maintain and enhance its Olive brand and reputation. • OP Group has a limited operating history for its Digital Platform. • OP Group may not be able to continue to grow its Digital Platform business rapidly. • Changes in insurance, consumer protection and related regulations may adversely affect OP Group’s business. • OP Group’s proprietary data analytics algorithms may not operate properly or as we expect them to. • Security incidents or real or perceived errors, failures or bugs in its systems or Olive website could impair its business. Risks Related to Being a Public Company • PubCo’s management team has limited experience managing a public company. • PubCo’s internal controls over financial reporting may not be effective and our independent registered public accounting firm may not be able to certify as to their effectiveness. • PubCo may amend the terms of the PubCo Public Warrants in a manner that may be adverse to holders of such PubCo Public Warrants with the approval by the holders of at least 50% of the then outstanding PubCo Public Warrants. Your unexpired PubCo Public Warrants may be redeemed prior to their exercise at a time that is disadvantageous to you, thereby making your PubCo Public Warrants worthless.
