such company or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities, and (b) familiar with the Securities Exchange Act
of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), and that the recipient will neither use, nor cause any third party to use, this Presentation or any information contained herein in
contravention of the Exchange Act, including, without limitation, Rule 10b-5 thereunder. This Presentation and information contained herein constitutes confidential information and is provided to you on the condition that you agree that you
will hold it in strict confidence and not use, discuss, reproduce, disclose, forward or distribute it in whole or in part without the prior written consent of ARYA, the Company and ListCo and is intended for the recipient hereof only. No
securities commission or securities regulatory authority in the United States or any other jurisdiction has in any way passed upon the merits of the Business Combination or the accuracy or adequacy of this Presentation. Certain monetary
amounts, percentages and other figures included in this Presentation have been subject to rounding adjustments. Certain amounts that appear in this Presentation may not sum due to rounding. Management's Estimates The Company has based its
estimates of the total addressable market and growth forecasts on a number of internal and third-party estimates and resources, including, without limitation, third party reports and the experience of the management team across the industries.
While the Company believes its assumptions and the data underlying its estimates are reasonable, these assumptions and estimates may not be correct and the conditions supporting such assumptions or estimates may change at any time, thereby
reducing the predictive accuracy of these underlying factors. In addition, the novelty of the markets for the Company’s products may make its assumptions and estimates more uncertain. As a result, the Company's estimates of the total
addressable market and growth forecasts for its products are subject to significant uncertainty and may prove to be incorrect. If third-party or internally generated data prove to be inaccurate or the Company makes errors in its assumptions
based on that data, the total addressable market for the Company's products may be smaller than it has estimated, its future growth opportunities and sales growth may be impaired, any of which could have a material adverse effect on the
Company's business, financial condition and results of operations. Forward-Looking Statements Certain statements in this Presentation may be considered “forward-looking statements” within the meaning of the “safe harbor” provisions of the
United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to future events or ARYA’s, the Company’s or ListCo’s future financial or operating performance. For example, any statements that refer
to expectations, projections or other characterizations of future events or circumstances, including post-Business Combination fully diluted equity value, the anticipated enterprise value of ListCo, expected ownership in ListCo, projections of
market opportunity and market share, the capability of the Company’s or ListCo’s business plans including its plans to expand, the sources and uses of cash from the Business Combination, any benefits of the Company’s partnerships, strategies or
plans as they relate to the Business Combination, anticipated benefits of the Business Combination and expectations related to the terms and timing of the Business Combination, the Company’s expected pro forma cash, the Company’s or ListCo’s
expected cash runway through 2025 or statements related to the Company’s or ListCo’s funding gap, funded business plan or use of proceeds, or other metrics or statements derived therefrom, are forward-looking statements. In some cases, you can
identify forward-looking statements by terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “future,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “propose,”
“seek,” “should,” “strive,” “will,” or “would” 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 may be beyond the control
of ARYA, the Company or ListCo and 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 ARYA and its management, the Company and its management and ListCo and its management, as the case may be, are inherently uncertain. Each of ARYA, the Company and ListCo caution you that these statements are based on a
combination of facts and factors currently known and projections of the future, which are inherently uncertain. There will be risks and uncertainties described in the proxy statement/prospectus included in the registration statement on Form S-4
(the “Registration Statement”) relating to the Business Combination, which is expected to be filed by ListCo with the U.S. Securities and Exchange Commission (the “SEC”), and described in other documents filed by ARYA or ListCo from time to
time with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Neither ARYA nor the
Company can assure you that the forward-looking statements in this presentation will prove to be accurate. In addition, new risks and uncertainties may emerge from time to time, and it may not be possible to identify and accurately predict the
potential impacts of any such risks and uncertainties that may arise in the future. 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 potential litigation, government or regulatory proceedings
that may be instituted against ARYA, the Company, ListCo or others; (3) the inability to complete the Business Combination due to the failure to obtain approval of the shareholders of ARYA, to obtain financing to complete the Business
Combination or to satisfy other conditions to closing; (4) the amount of redemption requests made by ARYA’s public shareholders; (5) 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
DISCLAIMER (CONT.) 3 PRIVATE AND CONFIDENTIAL Combination; (6) delays in
obtaining, adverse conditions in, or the inability to obtain regulatory approvals, or delays in completing regulatory reviews, required to complete the Business Combination; (7) the ability to meet stock exchange listing standards prior to or
following the consummation of the Business Combination; (8) the risk that the Business Combination disrupts current plans and operations of the Company or ListCo as a result of the announcement and consummation of the Business Combination; (9)
Adagio’s ability to remain compliant with the covenants of its existing debt, including any convertible or bridge financing notes; (10) ListCo’s ability to remain compliant with the covenants of the senior secured convertible notes that will be
issued in connection with the closing of the Business Combination; (11) the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, the ability of ListCo to grow and
manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (12) costs related to the Business Combination; (13) risks associated with changes in applicable laws or regulations and
the Company’s or ListCo’s international operations and operations in a regulated industry; (14) the possibility that the Company or ListCo may be adversely affected by other economic, business, and/or competitive factors; (15) the Company’s or
ListCo’s use of proceeds, post-Business Combination fully diluted equity value or fully diluted enterprise value, expected pro forma cash, expected cash runway or funding gap, estimates of expenses and profitability; and (16) the risks
described in the “Risk Factor Summary” included in this Presentation, and other risks and uncertainties set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in ARYA’s Annual Report on Form
10-K for the year ended December 31, 2023, its Quarterly Reports on Form 10-Q, and other documents filed, or to be filed, with the SEC. There may be additional risks that ARYA, the Company or ListCo do not presently know or that ARYA, the
Company or ListCo currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. Actual events and circumstances are difficult or impossible to predict and may materially
differ from assumptions. Many actual events and circumstances are beyond the control of ARYA, the Company and ListCo. Nothing in this Presentation should be regarded as a representation or warranty 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 in any specified time frame or at all. You should not place undue reliance on forward-looking statements,
which speak only as of the date they are made in this Presentation. Subsequent events and developments may cause those views to change. Neither ARYA, the Company nor ListCo undertakes any duty to update these forward-looking statements. Use of
Projections This Presentation contains forecasts with respect to the Company’s minimum total pro forma cash after expenses at announcement of the Business Combination and ListCo’s expected cash runway through 2025, based on current plans and
estimates of the Company. Neither ARYA’s, the Company’s nor ListCo’s independent auditors have audited, reviewed, compiled or performed any procedures with respect to such projected or forecasted information included 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. The inclusion of the forecasted information should not be relied upon as being necessarily indicative
of future results and should not be regarded as an indication that ARYA, the Company, ListCo or any other person considered, or now considers, the projections to be a reliable prediction of future events, and does not constitute an admission or
representation by any person that the expectations, beliefs, opinions, and assumptions that underlie such forecasts remain the same following the date of this Presentation, and readers are cautioned not to place undue reliance on any
prospective information. 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 cash or cash needs to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective cash or cash needs are indicative of the future performance of
the Company or ListCo or that actual cash or cash needs will not differ materially from those presented in the prospective financial information. ARYA, the Company and ListCo do not assume any obligation to update the projected information or
any other information in this Presentation, and do not expect to continue to disclose detailed prospective financial information going forward. Actual cash or cash needs may differ as a result of the completion of the Company’s or ListCo’s
applicable financial reporting period closing procedures, review adjustments and other developments that may arise between now and the time such financial information for the presented or projected periods is finalized. As a result, these
estimates are preliminary, may change and constitute forward-looking information, and are subject to significant risks and uncertainties. See “Forward-Looking Statements” above. Any such forecasted information presented herein was not prepared
with a view towards compliance with the published guidelines of the SEC, Regulation S-X promulgated under the Securities Act of 1933, as amended (the “Securities Act”) or any guidelines established by the American Institute of Certified Public
Accountants for the presentation and preparation of “prospective financial information.” Accordingly, the information and data presented in this Presentation may not be included, may be adjusted, or may be presented differently, in any proxy
statement or registration statement that may be filed in connection with a Business Combination. Industry and Market Data; Trademarks Certain information contained in the Presentation relates to or is based on studies, publications,
statistics and surveys from third-party sources, and on ARYA’s and the Company’s own internal estimates and research. In addition, 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. While ARYA and the Company believe that the third-party sources and ARYA’s and the Company’s internal research are reliable, such sources and research have not been
verified by any independent source. Any data on past performance or modeling contained herein is not an indication as to future performance. This information involves many assumptions and limitations, and you are cautioned not to give undue
weight to such industry and market data. The information contained in the third party citations referenced in this presentation is not incorporated by reference into this presentation. This Presentation may include trademarks, service marks,

information regarding their interests in the proposed Business Combination is included in the proxy statement/prospectus for the proposed Business Combination. No Offer and Non-Solicitation This Presentation does not constitute (i) a
solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination or (ii) an offer to sell, a solicitation of an offer to buy, or a recommendation to purchase any security of ARYA, the
Company, ListCo or any of their respective affiliates. No such offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act, or an exemption therefrom. The offering and resale
of the securities issuable in connection with the PIPE financing described herein has not been and will not be registered under the Securities Act or any applicable state securities laws. If the proposed Business Combination is entered into,
the PIPE financing will be offered and sold only to “qualified institutional buyers” (as defined in Rule 144A under the Securities Act) and institutional “accredited investors” (as defined in Rule 501(a)(1), (2), (3) or (7) promulgated under
the Securities Act) upon the consummation of the proposed Business Combination. Notice to investors in the European Economic Area / Prohibition of sales to EEA retail investors In member states of the European Economic Area (the “EEA”), this
Presentation and any offer if made subsequently is directed exclusively at persons who are “qualified investors” within the meaning of Article 2(e) of Regulation (EU) 2017/1129 (the “Prospectus Regulation”). The securities are not intended to
be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as
defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive 2002/92/EC (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a
professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation. Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended
the “PRIIPs Regulation”) for offering or selling the securities or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the securities or otherwise making them available to any
retail investor in the EEA may be unlawful under the PRIIPs Regulation. Notice to investors in the UK / Prohibition of sales to UK retail investors In the United Kingdom (“UK”), any offer of the securities will be made pursuant to an
exemption under Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (the “EUWA”) (the “UK Prospectus Regulation”) from a requirement to publish a prospectus for offers of securities.

meaning of Directive (EU) 2016/97 (as amended) as it forms part of the domestic law of the UK by virtue of the EUWA, where that customer would not qualify as a professional client as defined in UK MIFID II; or (iii) not a “qualified investor”
as defined in Article 2(e) of the UK Prospectus Regulation. Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of the domestic law of the UK by virtue of the EUWA (the “UK PRIIPs Regulation”) for
offering or selling the securities or otherwise making them available to retail investors in the UK has been prepared and, therefore, offering or selling the securities or otherwise making them available to any retail investor in the UK may be

its subsidiaries, prior to, or following, the consummation of the Business Combination, as the context requires. The risks presented below are some of the general risks to the business and operations of Adagio, ARYA Sciences Acquisition Corp IV
(“ARYA”) and Aja Holdco, Inc., of which Adagio will become a subsidiary following the consummation of the Business Combination (the “Post-Combination Company”), and such risks are not exhaustive. The list below is qualified in its entirety by
disclosures that will be contained in the future filings by ARYA and the Post-Combination Company, or of each of their respective affiliates or by third parties with the U.S. Securities and Exchange Commission (the “SEC”), including any
documents filed in connection with the proposed transaction. The risks presented in such filings may differ significantly from and may be more extensive than those presented below. The list below is not exhaustive, and you are encouraged to
perform your own investigation with respect to the business, financial condition and prospects of Adagio or the Post-Combination Company. You should carefully consider the following risk factors in addition to the information included in this
presentation. Adagio or the Post-Combination Company may face additional risks and uncertainties that are not presently known to it or that it currently deems immaterial, which may also impair Adagio’s or the Post-Combination Company’s business
or its financial condition. These risks speak only as of the date of this presentation, and neither the Company, ARYA nor the Post-Combination Company undertake any obligation to update the disclosure contained herein. In making any investment
decision, you should rely solely upon independent investigation made by you. You acknowledge that you are not relying upon, and have not relied upon, any of the summary of risks or any other statement, representation or warranty made by any

you have considered necessary to make an informed decision.
SELECTED RISK FACTORS (CONT.) 41 PRIVATE AND
CONFIDENTIAL The consummation of the Business Combination is subject to a number of conditions, and if those conditions are not satisfied or waived, the Business Combination may not be completed; Some of
ARYA’s, the Company’s or the Post-Combination Company’s officers and directors may have conflicts of interest that may influence them to approve the Business Combination without regard to your interests; ARYA’s directors and officers may have
interests in the Business Combination different from the interests of ARYA, the Company, the Post-Combination Company or their respective shareholders; If ARYA is unable to close certain financing transactions and sufficient shareholders
exercise their redemption rights in connection with the Business Combination such that there is less than $60 million of cash proceeds available from ARYA’s trust account and the financing transactions, then ARYA may lack sufficient funds to
consummate the Business Combination; A portion of the total outstanding shares of the Post-Business Combination Company is expected to be restricted from immediate resale but may be sold into the market in the near future; Sales of a
substantial number of shares of the Post-Business Combination Company’s common stock in the public market by existing stockholders could cause the Post-Business Combination Company’s share price to decline, even if our business is doing
well; ARYA’s shareholders will experience dilution due to (i) the issuance to existing Company security holders and investors in the financing transactions in connection with the Business Combination of securities, and (ii) additional sources
of dilution upon exercise or conversion of securities that will be issued in connection with or following the Business Combination (for instance, any earn-out shares, the PIPE Warrants, the Convert Warrants, the New Adagio Convertible Notes,
securities issued in connection with the post-Business Combination Company equity plan or employee share purchase plan), in each case potentially entitling recipients of such securities to a significant voting stake in the Post-Business
Combination Company; If ARYA does not consummated an initial business combination within the required time period, as may be extended at the option of ARYA Sciences Holdings IV (the “Sponsor”)), its public shareholders may receive only their
pro rata portion of the funds in the ARYA’s trust account that are available for distribution its public shareholders; There are no assurances that ARYA will be able to complete the Business Combination prior to its expiration date or that the
Sponsor will continue to exercise its monthly options to extend the time period ARYA has in order to consummate an initial business combination; The Company or Post-Business Combination Company stockholders cannot be certain of the value of
the merger consideration they will receive until the closing of the Business Combination; Because there are no current plans to pay cash dividends on the common stock of the Post-Business Combination Company for the foreseeable future, you may
not receive any return on investment unless you sell your ARYA ordinary shares or the Post-Business Combination Company common stock at a price greater than what you paid for it; ARYA, the Company and the Post-Business Combination Company
expect to incur substantial transaction fees and costs in connection with the Business Combination and the integration of their businesses; The costs related to the Business Combination could be significantly higher than currently
anticipated; ARYA’s, the Company’s or the Post-Business Combination Company’s business and operations could be negatively affected, or the Business Combination may be delayed or prevented from being completed, if they become subject to any
securities litigation or shareholder activism; In connection with the Business Combination, the Sponsor and ARYA’s directors, executive officers, advisors and their affiliates may elect to purchase Class A ordinary shares of ARYA from public
shareholders, which may reduce the public “float” of ARYA’s Class A ordinary shares;
SELECTED RISK FACTORS (CONT.) 42 PRIVATE AND
CONFIDENTIAL The proceeds held in ARYA’s trust account could be reduced and the per-share redemption amount received by ARYA shareholders may be less than $10.00 per share; The Nasdaq Stock
Market LLC may delist ARYA’s Class A ordinary shares from its exchange prior to the closing of the Business Combination or Nasdaq may not list the Post-Business Combination Company’s securities on its exchange, which could limit investors’
ability to make transactions in the Post-Business Combination Company’s securities and subject the Post-Business Combination Company to additional trading restrictions Following the closing of the Business Combination, an active trading market
for the Post-Business Combination Company’s common stock may not be available on a consistent basis to provide stockholders with adequate liquidity. The share price may be extremely volatile and shareholders could lose a significant part of
their investment; If, following the Business Combination, securities or industry analysts do not publish or cease publishing reports about the Post-Business Combination Company, its business, or its market, or if they change their
recommendations regarding the Post-Business Combination Company’s securities adversely, the price and trading volume of the securities of the Post-Business Combination Company could decline; The benefits of the Business Combination may not be
realized to the extent currently anticipated by ARYA, the Company and the Post-Business Combination Company, or at all. The ability to recognize any such benefits may be affected by, among other things, competition, the ability of the
Post-Business Combination Company to grow and manage growth profitably, maintain relationships with customers, landlords and suppliers and retain its management and key employees. If the Business Combination’s benefits do not meet the
expectations of investors, shareholders or financial analysts, the market price of ARYA’s or the Post-Business Combination Company’s securities may decline; The potential business combination will result in changes to the composition of the
board of directors of the Company and the composition of the board of directors of the Post-Business Combination Company which may affect the strategy of the Post-Business Combination Company; The ability of ARYA, the Company and the
Post-Business Combination Company to successfully effect the Business Combination and to be successful thereafter will be dependent upon the efforts of certain key personnel, including the Company’s key personnel. The loss of key personnel
could negatively impact the operations and profitability of the Post-Business Combination Company and its financial condition could suffer as a result; The Post-Business Combination Company does not have experience operating as a public
company subject to U.S. federal securities laws and may not be able to adequately develop and implement the governance, compliance, risk management and control infrastructure and culture required for a public company, including compliance with
the Sarbanes Oxley Act; The requirements of being a public company may strain the Post-Business Combination Company’s resources, incur increased costs and distract its management, which could make it difficult to manage its business,
particularly after the Post- Business Combination Company is no longer an emerging growth company; Subsequent to the completion of the Business Combination, the post-Business Combination company may be required to take write-downs or
write-offs, restructuring and impairment or other 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; As a
private company, the Company has not been required to document and test its internal controls over financial reporting nor has management been required to certify the effectiveness of its internal controls and its auditors have not been
required to opine on the effectiveness of its internal control over financial reporting. As such, material weaknesses may be identified in the Company’s or the Post-Business Combination Company’s internal control over financial reporting that
could lead to errors in the Post-Business Combination Company’s financial reporting, which could adversely affect the Post-Business Combination Company’s business and the market price of its securities; If the Post-Business Combination Company
fails to maintain an effective system of disclosure controls and internal controls over financial reporting, its ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired; If the
Post-Business Combination Company’s estimates or judgments relating to its critical accounting standards prove to be incorrect, or such standards change over time, its results of operations could be adversely affected; Because the
Post-Business Combination Company will become a publicly traded company by virtue of mergers in connection with the Business Combination as opposed to an underwritten initial public offering, there are no underwriters involved in the process,
which could result in less diligence being conducted on the Company or the Post-Business Combination Company than in an underwritten initial public offering; The ability of ARYA’s public shareholders to exercise redemption rights with respect
to a large number of ARYA’s public shares may not allow the Post-Business Combination Company to complete the most desirable business combination, fully fund the Company’s business plan, or changes thereto, or optimize the capital structure of
the Post-Business Combination Company; Past performance by ARYA’s management team or their affiliates, including Perceptive Advisors, ARYA Sciences Acquisition Corp., ARYA Sciences Acquisition Corp II, ARYA Sciences Acquisition Corp III, or
their respective business combination targets, may not be indicative of future performance of an investment in ARYA or the Post-Business Combination Company; The Post-Business Combination Company’s governing documents may include provisions
that may discourage takeover attempts; The Company’s operating and financial results, which were presented to the ARYA board of directors, may not prove accurate; Activities taken by existing ARYA shareholders to increase the likelihood of
approval of the Business Combination proposal and the other proposals to be described in the proxy statement/prospectus that will be filed in connection with the Business Combination could have a depressive effect on ARYA’s share price;
SELECTED RISK FACTORS (CONT.) 43 PRIVATE AND CONFIDENTIAL Upon executing a
definitive agreement with respect to the Business Combination by and among the Company, ARYA and the Post-Business Combination Company, ARYA may be prohibited from entering into certain transactions that might otherwise be beneficial to it or
its shareholders; The Business Combination may be completed even though material adverse effects may result from the announcement of the Business Combination, industry wide changes, and other causes; Delays in completing the Business
Combination may substantially reduce the expected benefits of the Business Combination; Adagio has, and the Post-Business Combination Company will have, broad discretion in the use of cash on hand and may not use it effectively. There is no
guarantee that Adagio or the Post-Business Combination Company will have sufficient capital to fund the Post-Business Combination Company business plan through 2025 and Adagio’s or the Post-Business Combination Company’s anticipated cash
runway through 2025 may be shorter than expected; The Post-Business Combination Company may not be able to remain compliant with the covenants of, and other obligations under, the senior secured convertible notes that will be issued in
connection with the closing of the Business Combination. Risks Related to Adagio’s Business Adagio is a medical device company that has incurred net losses in every period to date and
expects to continue to incur significant losses as it develops its business. Adagio’s growth prospects partially depend on its ability to accelerate the commercialization of its products and to capitalize on market opportunities. Adagio is
dependent on the success of its pipeline portfolio, which remains in the development stage and subject to on-going scientific and technical validation. Even if Adagio is able to launch its pipeline portfolio successfully, it may experience
material delays in its commercialization program relative to its current expectations. The commercialization of Adagio’s products will require Adagio to establish relationships and successfully collaborate with leading life science companies
and research institutions. The life sciences technology market is highly competitive. Competitors include new entrants and established companies, many of which have significantly greater resources than Adagio. If Adagio fails to compete
effectively, its business and results of operation will suffer. If Adagio is unable to establish manufacturing capacity by itself or with third-party partners in a timely and cost-effective manner, commercialization of its products would be
delayed, which would result in lost revenue and harm its business. If Adagio is unable to establish an effective network for commercialization, including effective distribution channels and sales and marketing functions, it may adversely
affect its business, results of operations, financial condition and prospects. Adagio’s operating results may fluctuate significantly in the future, which makes its future operating results difficult to predict and could cause its operating
results to fall below expectations or any guidance Adagio may provide. There is no assurance that Adagio will be able to execute on its business model, including achieving market acceptance of its products. Adoption of Adagio’s products
depends upon appropriate physician training, practice and patient selection. Even if Adagio’s products are commercialized and achieve broad scientific and market acceptance, if Adagio fails to improve them or introduce compelling new products,
its revenue and its prospects could be harmed. Adagio may need to raise additional capital to fund its development and commercialization plans. The size of the markets for Adagio’s products may be smaller than estimated, limiting Adagio’s
ability to successfully sell its products. Adagio is dependent on limited third-party suppliers and manufacturers for some of the components and materials used in its products, and the loss of any of these suppliers and manufacturers, or any
difficulties encountered by these suppliers and manufacturers in the production of Adagio’s products, could harm its business. If Adagio experiences a significant disruption in its information technology systems or security incidents, its
business could be adversely affected, including its ability to operate, the loss of confidential and proprietary information, increased remediation costs, and reputational damage. Adagio may be unable to manage its anticipated growth
effectively. Adagio may acquire other companies or technologies, or form strategic partnership with other companies, which could divert its management’s attention, increase its capital requirements, and otherwise disrupt its operations,
subject it to other risks and harm its operating results. If Adagio is unable to recruit and retain key executives and scientists, it may be unable to achieve its goals. Adagio’s products could have unknown defects or errors, which may give
rise to claims against it and adversely affect market adoption of its products. Consolidation in the medical device industry could have an adverse effect on Adagio’s revenue and results of operations. Since Adagio commercializes its products
outside of the United States, its international business could expose it to business, regulatory, political, operational, financial, and economic risks associated with doing business outside of the United States. Unfavorable U.S. or global
economic conditions as a result of the COVID-19 pandemic, political instability, natural disasters, or otherwise, could adversely affect Adagio’s ability to raise capital and its business, results of operations and financial condition. If
Adagio fails to maintain an effective system of internal control over financial reporting, the Post-Combination Company may not be able to accurately report its financial results in a timely manner or prevent fraud, which would harm its
business.
SELECTED RISK FACTORS (CONT.) 44 PRIVATE AND CONFIDENTIAL If the
Post-Combination Company estimates or judgments relating to its critical accounting policies are based on assumptions that change or prove to be incorrect, its results of operation could fall below its publicly announced guidance or the
expectations of securities analysts and investors, resulting in a decline in the market price of its common stock. If Adagio’s facilities become unavailable or inoperable, Adagio’s research and development program and commercialization launch
plan could be adversely affected, which could materially and adversely impact Adagio’s business and operations. Adagio uses hazardous chemicals and biological materials in its business. Any claims relating to improper handling, storage or
disposal of these materials could be time consuming and costly. Risks Related to Adagio’s Intellectual Property If Adagio is unable to obtain and maintain sufficient intellectual property protection for its
products and technology, or if the scope of the intellectual property protection obtained is not sufficiently broad, competitors could develop and commercialize products similar or identical to Adagio’s products, and Adagio’s ability to
successfully commercialize its products may be impaired. The U.S. law relating to the patentability of certain inventions in the life sciences technology industry is uncertain and rapidly changing, which may adversely impact Adagio’s existing
patents or its ability to obtain patents in the future. Adagio may not be able to protect its intellectual property rights throughout the world. Adagio may become involved in lawsuits to defend against third-party claims of infringement,
misappropriation or other violations of intellectual property or to protect or enforce Adagio’s intellectual property, any of which could be expensive, time consuming and unsuccessful, and may prevent or delay its development and
commercialization efforts. Issued patents covering Adagio’s products could be found invalid or unenforceable if challenged. If Adagio is unable to protect the confidentiality of its trade secrets, the value of its technology could be
materially adversely affected and its business could be harmed. Adagio may not be able to protect and enforce its trademarks and trade names, or build name recognition in its markets of interest thereby harming its competitive position. Patent
terms may be inadequate to protect Adagio’s competitive position of their products for an adequate amount of time. Obtaining and maintaining Adagio’s patent protection depends on compliance with various required procedures, document
submissions, fee payments and other requirements imposed by governmental patent agencies, and Adagio’s patent protection could be reduced or eliminated for non-compliance with these requirements. Adagio may be subject to claims that its
employees, consultants, independent contractors or any third parties that have access to Adagio’s confidential information or trade secrets have wrongfully used or disclosed confidential information of third parties or that its employees have
wrongfully used or disclosed trade secrets of their former employers. If Adagio cannot license rights to use technologies on reasonable terms, it may not be able to commercialize new products in the future. Adagio’s use of open source
software and failure to comply with the terms of the underlying open source software licenses could impose limitations on its ability to commercialize its products and provide third parties access to its proprietary software. Intellectual
property rights do not necessarily address all potential threats. Risks Related to Regulatory and Legal Compliance Matters Adagio expects to incur substantial expenses in its pursuit of regulatory clearances and approvals for its products
in the United States and can provide no assurances that it will obtain the necessary approvals from the FDA to market its products in the United States. Adverse findings in post-marketing vigilance or regulatory audits could subject Adagio to
suspension or withdrawal of its certificates of conformity, mandatory product recalls and significant legal liability, which could materially and adversely affect its business, financial condition and results of operations. Adagio may be
subject to enforcement action if Adagio engages in marketing of its products pursuant to improper regulatory classifications in the EU, including suspension or withdrawal of its certificates of conformity, mandatory product recalls and
significant legal liability, fines, penalties, and injunctions, which could materially and adversely affect its business, financial condition and results of operations.
SELECTED RISK FACTORS (CONT.) 45 PRIVATE AND
CONFIDENTIAL Adagio is subject to regulation by the FDA or other regulatory authorities in the future and would be required to obtain prior approval or clearance by the FDA or other regulatory authorities, which
could take significant time and expense and could fail to result in FDA clearance or approval for the intended uses Adagio believes are commercially attractive. Adagio’s products are subject to government regulation as medical devices by the
FDA and other regulatory agencies and the regulatory clearance or approval and the maintenance of continued and post-market regulatory compliance for such products will be expensive, time-consuming, and uncertain both in timing and in
outcome. Adagio is currently subject to, and may in the future become subject to additional, U.S. federal and state laws and regulations imposing obligations on how Adagio collects, stores and processes personal information. Adagio’s actual or
perceived failure to comply with such obligations could harm its business. Ensuring compliance with such laws could also impair Adagio’s efforts to maintain and expand its future customer base, and thereby decrease its revenue. If Adagio
expands its development and commercialization activities outside of the United States, it will be subject to an increased risk of inadvertently conducting activities in a manner that violates the U.S. Foreign Corrupt Practices Act and similar
laws. If that occurs, Adagio may be subject to civil or criminal penalties which could have a material adverse effect on its business, financial condition, results of operations and growth prospects. Adagio’s employees, independent
contractors, consultants, commercial partners, distributors and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements. Adagio is or will be subject to anti-corruption
and anti-bribery and anti-money laundering and similar laws, and non-compliance with such laws can subject it to administrative, civil and criminal fines and penalties, collateral consequences, remedial measures and legal expenses, all of which
could adversely affect its reputation, business and results of operations. Risks Related to Litigation and Regulation Adagio is subject to evolving laws and regulations that could impose substantial costs, legal prohibitions or unfavorable
changes upon its operations, and any failure to comply with these laws and regulations, including as they evolve, could result in litigation and substantially harm Adagio’s business and results of operations. Adagio is subject to risks
relating to disputes and other legal proceedings, product liability lawsuits, that may be time consuming and costly. Adagio’s lack of a trade compliance program leaves certain regulatory trade risk inherent in international business
unmitigated. If Adagio fails to comply with applicable international trade and sanctions regulations, Adagio may become subject to regulatory investigations, penalties, and fines. A trade compliance program including a screening process for
customers, independent contractors, and other third parties would help avoid violations, and if a violation occurred, having a trade compliance program is often a mitigating factor in determining penalties. Risks Related to Financing
Transactions ARYA and Adagio will incur significant transaction and transition costs in connection with the Business Combination. Whether or not the Business Combination is completed, the incurrence of these costs will reduce the
amount of cash available to the Post-Business Combination Company for other corporate purposes. Adagio or the Post-Business Combination Company is subject to financing risks. There are no guarantees that Adagio or the Post-Business Combination
Company can meet its financing needs for its operations and future investments at a reasonable cost or at all. Adagio or the Post-Business Combination Company is subject to risks relating to increased interest rates and any adverse
developments in the credit markets. There are risks associated with the senior secured convertible notes that will be issued by the Post-Business Combination Company in connection with closing and the Post-Business Combination Company may be
unable to remain in compliance with covenants or other obligations and restrictions under such convertible notes, which could materially impact the Post-Business Combination Company’s business, prospectus and plans or result in the
Post-Business Combination Company’s bankruptcy or insolvency. Risks Related to Tax Unanticipated tax laws or any changes in tax rates or in the application of the existing tax laws to Adagio may adversely impact its results of operations.
