Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (1) changes in domestic and foreign business, market, financial, political, and legal conditions; (2) the amount of redemptions by FIAC’s public stockholders in connection with the Contemplated Business Combination; (3) 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 proposed transactions; (4) the outcome of any legal proceedings that may be instituted against FIAC, DevvStream, the combined company or others; (5) the inability of the parties to successfully or timely consummate the Contemplated Business Combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the Contemplated Business Combination or that the approval of stockholders is not obtained; (6) changes to the proposed structure of the proposed transactions that may be required or appropriate as a result of applicable laws or regulations; (7) the ability to meet stock exchange listing standards following the consummation of the proposed transactions; (8) the risk that the proposed transactions disrupts current plans and operations of FIAC or DevvStream as a result of the announcement and consummation of the proposed transactions; (9) the ability to recognize the anticipated benefits of the proposed transactions, 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; (10) costs related to the proposed transactions; (11) changes in applicable laws or regulations; (12) risks related to extensive regulation, compliance obligations and rigorous enforcement by federal, state, and non-U.S. governmental authorities; (13) the possibility that FIAC, DevvStream or the combined company may be adversely affected by other economic, business, and/or competitive factors; (14) risks relating to DevvStream’s key intellectual property rights; (15) the Company’s estimates of expenses and profitability and underlying assumptions with respect to stockholder redemptions and purchase price and other adjustments; (16) various factors beyond management’s control, including general economic conditions and other risks, uncertainties and factors set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in FIAC’s final prospectus relating to its initial public offering, filed with the SEC on October 27, 2021, and other filings with the SEC, including the registration statement on Form S-4 to be filed by FIAC in connection with the transaction (the “Registration Statement”); and (17) certain other risks identified and discussed in DevvStream’s Annual Information Form for the year ended July 31, 2022, and DevvStream’s other public filings with Canadian securities regulatory authorities, available on DevvStream’s profile on SEDAR at www.sedarplus.ca.

 4  Financial Outlook  This Presentation contains statements that are considered financial outlook within the meaning of applicable Canadian securities laws (“Financial Outlook”), including statements regarding EBITDA margins on DevvStream’s Carbon Management and Carbon Investment segments, revenue and EBITDA margin estimates for DevvStream’s portfolio of projects. These statements are subject to the same assumptions, risk factors, limitations and qualifications as set forth above. In addition, certain key assumptions that underpin the Financial Outlook are as follows: the timing and duration of projects and the number of credits issued and the pricing of such credits. The methodology used by Devvstream to forecast revenue differs for different contracts, but generally relies on inputs from DevvStream’s operations staff and its contractual partners, which may prove to be inaccurate. With respect to any references to the Company’s EBITDA herein, the related revenue calculations include the Company’s interest in its joint venture with 1824400 Alberta Limited. Financial Outlook contained in this Presentation was prepared using the same accounting principles that the parties expect the combined company to use in preparing its financial statements for the applicable periods covered by such Financial Outlook. Financial Outlook was made as of the date of this Presentation and is provided for the purpose of describing anticipated sources, amounts and timing of revenue generation and the combined company’s business model. Although Financial Outlook presented in this Presentation is based on reasonable expectations developed by DevvStream’s management, the assumptions and estimates underlying such Financial Outlook are subject to significant business, economic, and competitive uncertainties and contingencies, many of which will be beyond the control of the combined company. Accordingly, the Financial Outlook are only estimates and are necessarily speculative in nature and actual results may vary materially from such Financial Outlook. Financial Outlook contained in this Presentation should not be used for purposes other than for which it is disclosed herein.   Non-IFRS Measures  In this Presentation, reference is made to EBITDA margins (“Non-IFRS measures”). DevvStream believes that these Non-IFRS measures are useful indicators with regard to understanding the business model of the combined company. These Non-IFRS measures are not generally accepted financial measures under International Financial Reporting Standards (“IFRS”) and do not have standardized meanings prescribed by IFRS. Investors are cautioned that none of these Non-IFRS measures should be considered as an alternative to earnings, earnings per share, or cash flow, as determined in accordance with IFRS. As there is no standardized method of calculating any of these Non-IFRS measures, DevvStream’s method of calculating each of them may differ from the methods used by other entities and, accordingly, DevvStream’s use of any of these Non-IFRS measures may not be directly comparable to similarly titled measures used by other entities. Accordingly, these Non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.   EBITDA margins is defined as earnings determined in accordance with IFRS, adding back the following line items form the consolidated income statement: interest, taxes, depreciation and amortization.  Non-GAAP Measures  This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principals (“GAAP”). These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items are significant in understanding and assessing DevvStream’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 DevvStream’s presentation of these measures may not be comparable to similarly-titled measures used by other companies. DevvStream believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to DevvStream’s financial condition and results of operations.  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, DevvStream 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.  Disclaimers (continued)

 Risk Factors  37  Certain factors may have a material adverse effect on our business, financial condition and results of operations. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that could have a material adverse effect on our business, financial condition and results of operations. If any of the following risks actually materialize, they could have a material adverse effect on our business, financial condition and results of operations. In that event, you could lose part or all of your investment. All references in this section to “we,” “our” or “us” refer to both the business of DevvStream Holdings Inc. and its subsidiaries (collectively, “Devvstream”) prior to the consummation of the contemplated business combination (the “Contemplated Business Combination”) with Focus Impact Acquisition Corp. (“FIAC”) and to the business of the post-business combination public company and its subsidiaries.  The list below is not exhaustive. It has been prepared solely for purposes of the private placement transaction and solely for potential private placement investors. It has not been prepared for any other purpose. You should carefully consider these risks and uncertainties, together with any other information provided to you, and you should carry out your own diligence and consult with your own financial and legal advisors concerning the risks and suitability of an investment in this offering before making an investment decision. Risks relating to the business and securities of Devvstream and FIAC as well as the Contemplated Business Combination will be disclosed in future documents filed or furnished by Devvstream or FIAC with the U.S. Securities and Exchange Commission (“SEC”), including the documents filed or furnished in connection with the Contemplated Business Combination. The risks and uncertainties presented in such filings will be consistent with those that would be required for a public company in its SEC filings, including with respect to the business and securities of Devvstream and FIAC as well as the Contemplated Business Combination. Accordingly, such risks and uncertainties may differ significantly from, and be more exhaustive than, those presented below.  Risks Related to Devvstream’s Business and Industry  We have a limited operating history and financial results make our future results, prospects and the risks we may encounter difficult to predict.  We may lack sufficient funds to achieve or planned business objectives and may seek to raise further funds through equity or debt financing or other means. An inability to access the capital or financial markets may limit our ability to fund our ongoing operations and execute our business plan to pursue investments that we may rely on for future growth.  Our business is substantially reliant on our technology partnership with Devvio, Inc., the termination of which could have a material adverse effect on our financial condition.  If the assumptions used to determine our market opportunity are inaccurate, our future growth rate may be affected and the potential growth of our business may be limited.  If demand for carbon credits does not grow as expected or develops more slowly than expected, our revenues may stagnate or decline and our business may be adversely affected.  The carbon credit market is competitive and we expect to face increasing competition in many aspects of our business, which could cause operating results to suffer.  The carbon market is an emerging market and its growth is dependent on the development of a commercialized market for carbon credits.  Because our business is significantly concentrated in carbon credits and the carbon market, we are susceptible to adverse economic or regulatory occurrences materially and adversely affecting our performance.  If we fail to retain our key personnel or if we fail to attract additional qualified personnel, we may not be able to achieve our anticipated level of growth and our business could suffer.  Certain of our directors, director nominees and/or officers may have interests that compete with ours.  The risks described herein are not the only ones Devvstream or FIAC face. Additional risks that are not currently known or that are currently believed to be immaterial may also impact our business, financial condition or results of operations. You should review the investor presentation and perform your own due diligence prior to making in investment in FIAC.  PLEASE SEE DEFINITIVE PROXY STATEMENT FOR ADDITIONAL RELEVANT DETAILS 

 Risk Factors (continued)  38  Risks Related to Devvstream’s Business and Industry (continued)  Increased scrutiny of ESG matters, including our completion of certain ESG initiatives, could have an adverse effect on our business, financial condition and results of operations, result in reputational harm and negatively impact the assessments made by ESG-focused investors when evaluating us.  The market price of shares of our common stock is subject to the price of carbon credits and may decline regardless of our operating performance.  Our due diligence process in connection with acquisitions, investments or streaming arrangements that we undertake may not reveal all relevant facts in connection with an acquisition, investment or streaming arrangement.  We may not realize the anticipated benefits of past or future acquisitions, and integration of these acquisitions may disrupt our business.  Our long-term success depends, in part, on properties and assets developed and managed by third party project developers, owners and operators.  We may have limited access to data and disclosure regarding the operations or projects for which we are not developer, owner or operator. This limited access may restrict our ability to assess the value and performance of our operations.  Our streams are largely contract-based and the terms of such contracts may not be honored by developers or operators of a project.  We may acquire future streams in which we have limited control and our interests in such streams may be subject to transfer or other related restrictions.  Physical and transition risks arising from climate change, including risks posed by the increased frequency or severity of natural and catastrophic events and regulations or policies related to climate change, may negatively impact our business and operations.  The threat of global economic, capital markets and credit disruptions pose risks to our business.  Inflation could adversely affect our business and results of operations.  Carbon markets, particularly the voluntary markets, are still evolving and there are no assurances that the carbon credits we purchase or generate through our investments will find a market.  We are subject to economic, political and other risks of doing business globally and in emerging markets.  Our insurance policies may be inadequate, may not cover all of our potential liabilities and may potentially expose us to uncoverable risks.  Fluctuations in foreign exchange rates may negatively affect our business.  Risks Related to Devvstream’s Information Technology and Intellectual Property  Failure of a key information technology system, process or site could have an adverse effect on our business.  If we suffer a security incident or breach, our reputation may be harmed and we may suffer significant liabilities, any of which would harm our business and results of operations.  The actual or perceived failure to comply with data privacy and data security laws, regulations and industry standards could have a material adverse effect on our reputation, results of operations or financial condition or have other adverse consequences.  Our inability to retain licenses to intellectual property owned by third parties may negatively impact our financial results and operations.  If we are unable to obtain, protect or enforce our rights in proprietary technology, brands or other intellectual property, our competitive advantage, business, financial condition, results of operations, cash flow and prospects could be adversely affected.  The risks described herein are not the only ones Devvstream or FIAC face. Additional risks that are not currently known or that are currently believed to be immaterial may also impact our business, financial condition or results of operations. You should review the investor presentation and perform your own due diligence prior to making in investment in FIAC.  PLEASE SEE DEFINITIVE PROXY STATEMENT FOR ADDITIONAL RELEVANT DETAILS 

 Risk Factors (continued)  39  Risks Related to Legal, Compliance and Regulations  Our business and current and future operations are subject to liabilities and operating restrictions arising from regulatory requirements. We will be subject to regulatory requirements in multiple jurisdictions, which impose substantial compliance requirements on our operations. Our operating costs could be significantly increased in order to comply with new or more stringent regulatory standards in the jurisdictions in which we operate.  From time to time, we may be involved in litigation, regulatory actions or government investigations and inquiries, which could have an adverse impact on our profitability and financial position.  It may be difficult for our stockholders to acquire jurisdiction and enforce liabilities against our assets based in international jurisdictions.  We may not be able to have all our projects validated through a compliance market or by an internationally recognized carbon credits standard body.  Carbon pricing initiatives are based on scientific principles that are subject to debate. Failure to maintain international consensus may negatively affect the value of carbon credits.  Our business may require numerous permits, licenses and other approvals from various governmental agencies, and the failure to obtain or maintain any of them, or delays in obtaining them, could materially adversely affect us.  Our cross-border operations require us to comply with anti-bribery and anti-corruption laws.  We are subject to legal risks associated with our global operations.  Carbon trading is heavily regulated and new legislation in the jurisdictions in which we operate may materially impact our operations.  Risks Related to the Contemplated Business Combination  Events, changes or other circumstances, many of which are beyond the control of Devvstream and FIAC, could give rise to the termination of negotiations and any subsequent definitive agreements with respect to the Contemplated Business Combination.  The Contemplated Business Combination may disrupt current plans and operations of Devvstream.  If the Contemplated Business Combination's benefits do not meet expectations of investor or securities analysts, the market price of FIAC's securities, or following the consummation of the Contemplated Business Combination, the combined company's securities, may decline.  The valuation ascribed to the combined company may not be indicative of the price that will prevail in the trading market following the Contemplated Business Combination. If an active market for the combined company's securities develops and continues, the trading price of the combined company's securities following the Contemplated Business Combination could be volatile and subject to wide fluctuations in response to various factors, which could contribute to the loss of all or part of your investment.  Both FIAC and Devvstream will incur significant transactions costs in connection with the Contemplated Business Combination.  The risks described herein are not the only ones Devvstream or FIAC face. Additional risks that are not currently known or that are currently believed to be immaterial may also impact our business, financial condition or results of operations. You should review the investor presentation and perform your own due diligence prior to making in investment in FIAC.  PLEASE SEE DEFINITIVE PROXY STATEMENT FOR ADDITIONAL RELEVANT DETAILS 

 Risk Factors (continued)  40  Risks Related to the Contemplated Business Combination (continued)  FIAC and Devvstream may not successfully or timely consummate the Contemplated Business Combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the Contemplated Business Combination or that the approval of the stockholders of FIAC or Devvstream is not obtained.  The consummation of the Contemplated Business Combination is subject to a number of conditions and if those conditions are not satisfied or waived, the Contemplated Business Combination agreement may be terminated in accordance with its terms and the Contemplated Business Combination may not be completed.  Since Focus Impact Sponsor, LLC (“FIAC Sponsor”) has interests that are different, or in addition to (and which may conflict with), the interests of the FIAC public stockholders, a conflict of interest may exist in determining whether the Contemplated Business Combination is appropriate as a business combination. Such interests include that the FIAC Sponsor will lose its entire investment in FIAC if a business combination is not completed.  There is no guarantee that a stockholder's decision whether to redeem its shares for a pro rata portion for the trust account will put the stockholder in a better future economic position.  Legal proceedings in connection with the Contemplated Business Combination, the outcomes of which are uncertain, could delay or prevent the completion of the Contemplated Business Combination.  Following the consummation of the Contemplated Business Combination, the combined company will incur significant increased expenses and administrative burdens as a public company, which could have an adverse effect on its business, financial condition and results of operation.  Changes in laws or regulations, or a failure to comply with any laws and regulations, may adversely affect Devvstream's or the combined company's business, including the ability of the parties to consummate the Contemplated Business Combination, and results of operation of Devvstream or the combined company.  The risks described herein are not the only ones Devvstream or FIAC face. Additional risks that are not currently known or that are currently believed to be immaterial may also impact our business, financial condition or results of operations. You should review the investor presentation and perform your own due diligence prior to making in investment in FIAC.  PLEASE SEE DEFINITIVE PROXY STATEMENT FOR ADDITIONAL RELEVANT DETAILS
