In addition, the analyses of Baird Medical and ExcelFin contained herein are not, and do not purport to be, appraisals of the securities, assets or business of Baird Medical, ExcelFin or any other entity . Industry and Market Data . Certain information contained in this Presentation relates to or is based on studies, publications, surveys and the Baird Medical’s own internal estimates and research, including the “Global Market Study of Ablation Therapy - Independent Market Research Report” (the “Frost & Sullivan Report”) commissioned by Baird Medical and prepared by Frost & Sullivan, a third - party global research organization . The Frost & Sullivan Report was prepared based on various interviews conducted on a best - effort basis with industry experts and competitors . The study used 2021 as the base year for analysis and 2022 - 2024 for forecast . Certain figures from 2021 were not available from public statistical sources at the time of writing . In such cases, Frost & Sullivan used the latest information available or made projections based on historical trends . Under circumstances where information was not available, Frost & Sullivan’s in - house analysis was leveraged using appropriate models and indicators to arrive at an estimate . All of the market data included in this Presentation involves a number of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions .

Baird Medical Trademarks . ExcelFin and Baird Medical own or have rights to various trademarks, service marks and trade names that they use in connection with the operation of their respective businesses . This Presentation may also contain trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners . The use or display of third parties’ trademarks, service marks, trade names or products in this Presentation is not intended to, and does not imply, a relationship with ExcelFin or Baird Medical an endorsement or sponsorship by or of ExcelFin or Baird Medical . Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this Presentation may be listed without the TM, SM, © or ® symbols, but such references are not intended to indicate, in any way, that ExcelFin or Baird Medical will not assert, to the fullest extent under applicable law, their rights or the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights . Non - GAAP Financial Measures . This Presentation includes adjusted EBITDA margin, which is not presented in accordance with generally accepted accounting principles (“GAAP”) . 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 Baird Medical’s financial results . You should be aware that the Baird Medical's presentation of these measures may not be comparable to similarly - titled measures used by other companies . 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 . Baird Medical believes non - GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Baird Medical's financial condition and results of operations . Baird Medical believes that the use of non - GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing Baird Medical's financial measures with other similar companies, many of which present similar non - GAAP financial measures to investors . N on - 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 . A reconciliation of historical adjusted EBITDA to net income is provided in the tables at the end of this Presentation . With respect to projected adjusted EBITDA and adjusted EBITDA margin, 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, Baird Medical 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 . For the same reasons, Baird Medical is unable to address the probable significance of the unavailable information, which could be material to future results . Participants in the Solicitation . Baird Medical and ExcelFin and their respective directors and executive officers may be deemed participants in the solicitation of proxies from ExcelFin’s stockholders with respect to the proposed Business Combination . A list of the names of ExcelFin’s directors and executive officers and a description of their interests in ExcelFin is contained in ExcelFin’s final prospectus relating to its initial public offering, dated October 22 , 2021 , and in ExcelFin’s Annual Report on Form 10 - K, dated March 30 , 2023 , which were filed with the SEC and are available free of charge at the SEC’s web site at www . sec . gov, or by directing a request to ExcelFin Acquisition Corp . , 1 00 Kingsley Park Drive, Fort Mill, South Carolina 29715 . Other information regarding Baird Medical, and the other participants in the proxy solicitation and a description of their direct and indirect interests, by security holdings or otherwise, will be contained in the proxy statement/prospectus and other relevant materials to be filed with the SEC . Investors and security holders of Baird Medical and ExcelFin are urged to read the proxy statement/prospectus and other relevant documents that will be filed with the SEC carefully and in their entirety when they become available because they will contain important information about the proposed Business Combination . Investors and security holders will be able to obtain free copies of the proxy statement and other documents containing important information about Baird Medical and ExcelFin through the website maintained by the SEC at www . sec . gov . Copies of the documents filed with the SEC by ExcelFin can be obtained free of charge by directing a written request to ExcelFin Acquisition Corp . , 1 00 Kingsley Park Drive, Fort Mill, South Carolina 29715 .

(“ExcelFin”) or other relevant parties to the proposed business combination (the “Business Combination”) of ExcelFin and Baird Medical. Risk Factors Relating to Baird Medical's Business and Industry • Baird Medical's ability to maintain profitability depends on the commercial success of its microwave ablation (“MWA”) and rel ate d medical device products. • Baird Medical's success depends on maintaining its relationships with hospitals, key opinion leaders, and distributors and to ef fectively market to hospitals through public tender processes. • Potential quality defects in Baird Medical's products may cause safety issues, expose Baird Medical to potential product liab ili ty claims, government fines and reputational harm. • If Baird Medical is unable to keep up the demand for its MWA and related medical device products, physicians may turn to alte rna tive treatment methods. • Baird Medical may require additional capital to support its business plan and anticipated growth, and such capital may not be av ailable on acceptable terms, or at all. • Baird Medical's forecasts and projections (particularly those related to the size of the market, target populations for Baird Me dical's products and future exchange rates between the United States dollar and Chinese yuan) are based upon assumptions, analyses and estimates which may prove to be incorrect or inaccurate, wh ich could cause Baird Medical's actual results to differ materially from those forecasted or projected. • Baird Medical may be unable to obtain, maintain or renew the regulatory filings, registration certificates, permits, licenses an d other certifications and approvals (or to complete the testing of its products required to obtain the same) from regulatory authorities needed to commercialize its microwave medical devices and r equ ired for its business and operations in a timely manner, or at all. • Baird Medical may be unable to develop or successfully market new or commercially viable products and technologies or improve it s existing products and technologies in a timely manner, or at all, to respond to changes in market conditions, technological advancements, or the highly competitive industry in which it operates. • Future success depends on Baird Medical's ability to retain members of its management team and key personnel and to attract, ret ain and motivate qualified personnel at a cost - effective rate. • Baird Medical's related party transactions present possible conflicts of interest that could adversely impact on its business, financial conditions and results of opera ti ons. • Negative publicity and allegations involving Baird Medical, its shareholders, directors, officers, employees and business par tne rs may adversely affect Baird Medical's business. • If Baird Medical becomes subject to legal or contractual disputes, governmental investigations or administrative proceedings, it may incur substantial costs and its management team’s attention may be diverted. • Insurance coverage maintained by Baird Medical may be inadequate to protect Baird Medical from the liabilities that it may in cur . • Unfavorable global economic conditions, including inflation, recession, bank failures, and decreases in consumer spending pow er or confidence, including a severe or prolonged downturn in the PRC or global economy, could materially and adversely affect Baird Medical's business, financial condition or results of oper ati ons. • Betters may be required to repurchase its previously issued Series C convertible redeemable preference shares. • Intellectual property litigation and infringement claims by or against Baird Medical, including priority disputes, inventorsh ip disputes or similar proceedings, could cause Baird Medical to incur significant expenses, distract Baird Medical's management, require Baird Medical to redesign or discontinue selling the affec ted product, invalidate Baird Medical’s patents or trademarks, or harm Baird Medical’s business prospects and financial position. • Baird Medical may be unable to obtain and maintain effective or sufficiently broad patent and other intellectual property rig hts for its products and pipeline products. • The planned expansion of Baird Medical's business to additional and emerging markets internationally is expected to lead to i ncr eased exposure to market, regulatory, political, operational, financial and economic risks, including risks relating to China’s relationship with other countries. • Baird Medical's business is largely focused on a single technology (MWA) in a single geographic region (China), which could m agn ify the adverse impact of certain risks.

Baird Medical Risk Factors (cont’d) 30 Risks Related to Doing Business in China • Medical device manufacturers in China are subject to extensive safety regulations and requirements, which can lead to increas ed compliance costs and heightened risks of inadvertent incidents of noncompliance. Baird Medical may be subject to fines for its failure to comply with the relevant PRC laws and regulations rel ati ng to safety facilities. • The Chinese government has substantial influence over Baird Medical's activities and may intervene with its operations, which co uld result in a material change of its operations and/or cause the value of its securities to decline or become worthless. • PRC regulation on loans to, and direct investment in, Baird Medical's PRC subsidiary by offshore holding companies and govern men tal control in currency conversion may delay or prevent Baird Medical from using the proceeds of the Business Combination to make loans to or make additional capital contributions to Bair d M edical's PRC subsidiary. • The China Securities Regulatory Commission’s (“CSRC”) Trial Measures for China - based companies seeking to conduct overseas offer ing and listing in foreign markets could significantly limit or completely hinder Baird Medical's ability to offer or continue to offer its ordinary shares to investors and could cause the val ue of its ordinary shares to significantly decline or become worthless. • If Baird Medical fails to comply with environmental, health and safety laws and regulations, Baird Medical could be subject t o f ines or penalties or incur costs that could have a material adverse effect on the success of its business. • There are uncertainties under the EIT Law relating to withholding tax liabilities for PRC entities, and dividends payable by Bai rd Medical's PRC subsidiary may not qualify for certain treaty benefits. • Baird Medical may rely on dividends and other equity distributions paid by its PRC subsidiary to fund its cash and financing req uirements, and the PRC subsidiary’s restrictions on paying dividends or making other payments could restrict Baird Medical's ability to satisfy liquidity requirements and have a material and adv ers e effect on Baird Medical's business. Risks Related to Ownership of PubCo Ordinary Shares • Following the closing of the potential Business Combination, an active trading market for PubCo’s shares may not be available on a consistent basis to provide shareholders with adequate liquidity and may lead to significant volatility in the PubCo’s share price. • Concentration of ownership among existing executive officers, directors and their affiliates may prevent new investors from i nfl uencing significant corporate decisions. • The Combined Company does not expect to declare any dividends in the foreseeable future. Shareholders may not receive any ret urn on their investment unless they sell their shares. • Substantial sales of PubCo’s stock in the public market by existing shareholders, particularly after any lock - up period ends, co uld cause the PubCo’s share price to decline. • There can be no assurance that PubCo ordinary shares will be approved for listing on Nasdaq upon the Closing, or that PubCo w ill be able to comply with the continued listing standards of Nasdaq or any other applicable exchange listing standards, which could limit investors’ ability to make transactions in PubCo’s secu rit ies. • PubCo’s lack of public company experience and a lack of research or reports about PubCo, its business, or its market, or adve rse recommendations against PubCo Ordinary Shares by securities and industry analysts may adversely affect PubCo’s business and the price and trading volume of its ordinary shares. • PubCo’s issuance of additional capital stock in connection with financings, acquisitions, investments, stock incentive plans or otherwise will dilute all other stockholders Risks Relating to Redemption • The ability to execute ExcelFin’s strategic plan could be negatively impacted to the extent a significant number of stockhold ers choose to redeem their shares. • There is no guarantee that an ExcelFin stockholder’s decision to redeem their shares for a pro rata portion of the Trust Acco unt will economically benefit the stockholder. • Failure to comply with redemption requirements could prevent an ExcelFin stockholder from redeeming their shares of ExcelFin Cla ss A Common Stock. • If ExcelFin stockholders fail to properly demand redemption rights, they cannot convert their ExcelFin Class A Common Stock i nto a pro rata portion of the Trust Account. • Holders who redeem their public shares of ExcelFin Class A Common Stock may continue to hold or exercise any ExcelFin Public War rants that they own in accordance with their terms, which may result in additional dilution. • A new 1% U.S. federal excise tax could be imposed on ExcelFin in connection with redemptions by ExcelFin stockholders of Clas s A Common Stock in connection with the Business Combination.

Baird Medical Risk Factors (cont’d) 31 Risks Relating to ExcelFin, PubCo and the Business Combination • If ExcelFin does not consummate the Business Combination by the termination date of May 25, 2024, ExcelFin will have to cease al l operations except to wind up, redeem all of its public shares and liquidate, or seek approval of its stockholders to extend the termination date. • If the funds held outside of ExcelFin’s Trust Account are insufficient to allow ExcelFin to operate until at least May 25, 20 24 (or such later date as may be extended by means of an amendment to the ExcelFin Certificate of Incorporation), ExcelFin’s ability to complete the Business Combination may be adversely affected. • The working capital available to the Combined Company after the Business Combination will be reduced to the extent ExcelFin’s st ockholders exercise their redemption rights in connection with the Business Combination and will also be reduced to the extent of Baird Medical's and ExcelFin’s transaction expenses, which wi ll be payable by the Combined Company, which may adversely affect the future operations of the Combined Company. • The only significant asset of the Combined Company will be ownership of 100% of the Company Shares, and the Combined Company doe s not currently intend to pay dividends on its common stock, so your ability to achieve a return on your investment will depend on appreciation in the price of PubCo Ordinary Shares. • ExcelFin will incur significant transaction and transition costs in connection with the Business Combination, which could be sig nificantly higher than currently anticipated. If ExcelFin fails to consummate the Business Combination, it may not have sufficient cash available to pay such costs. • ExcelFin’s independent registered public accounting firm’s report contains an explanatory paragraph that expresses substantial doubt abo ut ExcelFin’s ability to continue as a going concern, since ExcelFin will cease all operations except for the purpose of liquidating if ExcelFin is unable to complete an initial business combination by May 25, 2024 (or such later date as may be extended by means of an amendment to the ExcelFin Certificate of Incorporation). • U.S. regulatory authorities, including the SEC, have recently enacted and proposed rules impacting special purpose acquisitio n c ompanies that could increase ExcelFin’s costs, cause the Business Combination to be less attractive to ExcelFin’s shareholders or constrain circumstances under which it could be completed. • Recent increases in inflation and interest rates in the United States and elsewhere could make it more difficult for ExcelFin to consummate the Business Combination. • ExcelFin and Baird Medical have no history operating as a combined company. The unaudited pro forma condensed consolidated co mbi ned financial information may not be an indication of the Combined Company’s financial condition or results of operations following the Business Combination or would have been, and ac cor dingly, you have limited financial information on which to evaluate Baird Medical and your investment decision. • The Business Combination remains subject to conditions that ExcelFin cannot control, which if not satisfied or waived, the Bu sin ess Combination may not be consummated. • The Business Combination may be completed even though material adverse effects may result from its announcement, industry - wide c hanges and other causes. • The exercise of ExcelFin’s discretion in agreeing to changes to or waivers of terms of the Business Combination may result in a conflict of interest when determining whether such changes or waivers of conditions are appropriate and in ExcelFin’s best interests. • The Sponsor, and ExcelFin’s directors and officers, have conflicts of interest in determining to pursue the Business Combinat ion with Baird Medical, since certain of their interests, and certain interests of their affiliates and associates, are different from or in addition to (and which may conflict with) the interest s o f ExcelFin’s stockholders. • ExcelFin’s Sponsor and affiliates will lose their entire investment of privately placed shares (consisting of founder shares) in ExcelFi n if the Business Combination is not completed and, therefore, they may have had a conflict of interest in identifying and selecting Baird Medical to close the Business Combination. • Since the Sponsor, and ExcelFin’s executive officers and directors will not be eligible for reimbursements of their out - of - pocke t expenses if the Business Combination is not completed, a conflict of interest may arise in determining whether Baird Medical is appropriate for ExcelFin’s initial business combination to close t he transaction. • Deferred underwriting fees in connection with the IPO will not be adjusted to account for redemptions by ExcelFin’s public stockholders; if ExcelFin’s public stockholders exercise their redemption rights, the amount of effective total underwriting commissions as a percentage of the aggregate proceeds from the IPO will in cre ase. • ExcelFin’s ability to successfully effect the Business Combination and the Combined Company’s ability to successfully operate th e business will be largely dependent upon the key personnel’s efforts.

Baird Medical Risk Factors (cont’d) 32 • The benefits of the potential Business Combination may not be realized to the extent currently anticipated by ExcelFin and Ba ird Medical, or at all. If the Business Combination’s benefits do not meet expectations of investors, stockholders or analysts, the market price of ExcelFin’s or PubCo’s securities may decline. • The Sponsor and ExcelFin’s directors and officers have agreed to vote in favor of its initial business combination, regardles s o f how ExcelFin’s public stockholders vote. • The Sponsor, ExcelFin’s directors and officers and advisors and their respective affiliates may elect to purchase shares from ho lders of ExcelFin’s public shares in connection with the Business Combination, which may influence the vote on the Business Combination and reduce the public “float” of ExcelFin Class A Commo n S tock. • The PubCo ordinary shares to be received by ExcelFin’s stockholders due to the Business Combination have different rights fro m E xcelFin Class A Common Stock. • ExcelFin’s stockholders will have a reduced ownership and voting interest and less influence over management after consummati on of the Business Combination. • Following the Business Combination, PubCo may be required to take write - downs or write - offs, restructuring and impairment or oth er charges that could have a significant negative effect on its financial condition, results of operations and stock price, which could cause you to lose some or all of your investment. • ExcelFin’s warrants and founder shares may have an adverse effect on the market price of ExcelFin Class A Common Stock and PubCo ordinar y shares. • If redemptions exceed the threshold allowable for ExcelFin to consummate the Business Combination, the ExcelFin Public Warrants will expire worthless. • If PubCo is characterized as a passive foreign investment company for U.S. federal income tax purposes, its U.S. shareholders ma y suffer adverse tax consequences. • There may be tax consequences of the Business Combination that adversely affect holders of ExcelFin Class A Common Stock or E xce lFin Public Warrants. • The IRS may not agree that PubCo should be treated as a non - U.S. corporation or a “surrogate foreign corporation” for U.S. feder al income tax purposes. • Future resales of PubCo ordinary shares may cause their market price to drop significantly. • Anti - takeover provisions in PubCo’s governing documents, by - laws and provisions of Cayman Islands Law could impair limit future share price and entrench management. • ExcelFin’s governing documents limit its stockholders’ choice of judicial forum to the Court of Chancery of the State of Dela war e for certain stockholder litigation matters against ExcelFin, and its directors, officers or stockholders. • If third parties bring claims against ExcelFin, the Trust Account proceeds could be reduced and the per - share redemption amount may be less than $10.20 per share. • ExcelFin directors may decide not to enforce indemnification obligations of ExcelFin’s Sponsor, reducing the funds in the Trust Account for distribution to ExcelFin’s public stockholders. • ExcelFin’s stockholders may be held liable for claims by third parties against ExcelFin to the extent of distributions receiv ed by them. • A securities class action and derivative lawsuits targeting ExcelFin could result in substantial costs and may delay or preve nt completion of the Business Combination. • The Sponsor and ExcelFin’s directors, officers, advisors or their affiliates may elect to purchase shares of ExcelFin Class A Co mmon Stock from ExcelFin’s stockholders, which may influence a vote on a proposed business combination and reduce the public float of ExcelFin’s issued and outstanding capital stock. • If a stockholder or a “group” of stockholders are deemed to hold in excess of 15% of ExcelFin Class A Common Stock, such stoc kho lder or group will lose the ability to redeem all such shares in excess of 15% of ExcelFin Class A Common Stock. • A voluntary or involuntary bankruptcy petition by or against ExcelFin prior to distributions may reduce the per share amount to be received by ExcelFin’s stockholders. • In completing the Business Combination, management’s focus and resources may be diverted from operational matters and other s tra tegic opportunities. • The Combined Company may incur successor liabilities due to conduct arising prior to the completion of the Business Combinati on. • The restatement of previously issued audited consolidated financial statements may affect investor confidence and raise reput ati onal issues and may subject us to additional risks and uncertainties, including increased professional costs and the increased possibility of legal proceedings and regulatory inquiries.
