(the “Company” or “ironSource”) and for no other purpose.

Viewers of this presentation should make their own evaluation of the Company and of the relevance and accuracy of the information and should make such other investigations as they deem necessary. This Presentation does not constitute (i) a solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Proposed Business Combination or (ii) an oﬀer to sell, a solicitation of an oﬀer to buy, or a recommendation to purchase any security of TBA, the Company, or any of their respective aﬃliates, nor shall there be any sale of securities in any jurisdiction in which such oﬀer, solicitation or sale would be unlawful prior to registration or qualiﬁcation under the securities laws of any such jurisdiction. No oﬀering of securities shall be made expect by means of a prospectus meeting the requirements of the U.S. Securities Act of 1933, as amended (the “Securities Act”). You should not construe the contents of this Presentation as legal, tax, accounting or investment advice or a recommendation. You should consult your own counsel and tax and ﬁnancial advisors as to legal and related matters concerning the matters described herein, and, by accepting this Presentation, you conﬁrm that you are not relying upon the information contained herein to make any decision. The distribution of this Presentation may also be restricted by law and persons into whose possession this Presentation comes should inform themselves about and observe any such restrictions. The recipient acknowledges that it is (a) aware that the United States securities laws prohibit any person who has material, non-public information concerning a company from purchasing or selling securities of 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 reproduce, disclose, forward or distribute it in whole or in part without the prior written consent of TBA and the Company and is intended for the recipient hereof only. Neither the Company nor any recipient of this Presentation will be an investment advisory client of Thoma Bravo; recipients must consult their own advisors for investment advice, and investment performance of Thoma Bravo presented herein is for illustrative purposes only, to indicate the experience of relevant Thoma Bravo personnel working in the Company’s industry. 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 TBA’s or the Company’s future ﬁnancial or operating performance. For example, projections of future Adjusted EBITDA and other metrics are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may”, “should”, “expect”, “intend”, “will”, “estimate”, “anticipate”, “believe”, “predict”, “potential” or “continue”, or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to diﬀer materially from those expressed or implied by such forward looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by TBA and its management, and the Company and its management, as the case may be, are inherently uncertain. Nothing in this Presentation should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. Neither TBA nor the Company undertakes any duty to update these forward-looking statements. Non-GAAP Financial Measures This Presentation includes certain ﬁnancial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, Adjusted EBITDA and certain ratios and other metrics derived there from. These non-GAAP ﬁnancial measures are not measures of ﬁnancial performance in accordance with GAAP and may exclude items that are signiﬁcant in understanding and assessing the Company’s ﬁnancial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash ﬂows from operations or other measures of proﬁtability, liquidity or performance under GAAP. You should be aware that the Company’s Presentation of these measures may not be comparable to similarly-titled measures used by other companies. The Company believes these non-GAAP measures of ﬁnancial results provide useful information to management and investors regarding certain ﬁnancial and business trends relating to the Company’s ﬁnancial condition and results of operations. The Company believes that the use of these non-GAAP ﬁnancial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing the Company’s ﬁnancial measures with other similar companies, many of which present similar non-GAAP ﬁnancial measures to investors. These non-GAAP ﬁnancial measures are subject to inherent limitations as they reﬂect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP ﬁnancial measures. Please refer to footnotes where presented on each page of this Presentation or to the appendix found at the end of this Presentation for a reconciliation of these measures to what the Company believes are the most directly comparable measure evaluated in accordance with GAAP. This Presentation also includes certain projections of non-GAAP ﬁnancial measures. Due to the high variability and diﬃculty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP ﬁnancial measures without unreasonable eﬀort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward-looking non-GAAP ﬁnancial measures is included. Certain monetary amounts, percentages and other ﬁgures included in this Presentation have been subject to rounding adjustments. Certain other amounts that appear in this Presentation may not sum due to rounding. Use of Projections This Presentation contains ﬁnancial forecasts with respect to the Company’s projected ﬁnancial results, including Revenue and Adjusted EBITDA, for the Company's ﬁscal years 2021 through 2022. The Company's independent auditors have not audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this Presentation. These projections should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the prospective ﬁnancial information are inherently uncertain and are subject to a wide variety of signiﬁcant business, economic and competitive risks and uncertainties that could cause actual results to diﬀer materially from those contained in the prospective ﬁnancial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of the Company or that actual results will not diﬀer materially from those presented in the prospective ﬁnancial information. Inclusion of the prospective ﬁnancial information in this Presentation should not be regarded as a representation by any person that the results contained in the prospective ﬁnancial information will be achieved. Industry and Market Data In this Presentation, TBA and the Company rely on and refer to certain information and statistics obtained from third-party sources which they believe to be reliable, including independent industry reports from App Annie, AppsFlyer, Apptopia, eMarketer, Newzoo, Omdia and Sensor Tower. Neither TBA nor the Company has independently veriﬁed the accuracy or completeness of any such third-party information. Additional Information The Company intends to ﬁle with the SEC a proxy statement / prospectus on Form F-4 relating to the Proposed Business Combination, which will be mailed to TBA’s shareholders once deﬁnitive.

Adverse events relating to this ecosystem, including events related to our customers or their apps, could have a negative impact on our business 12. Our business is subject to risks generally associated with the mobile gaming industry 13. If we or our competitors fail to detect or prevent fraud on our respective platforms, or malware intrusion into the systems or devices of customers and their users, customers could lose conﬁdence in our or our competitors’ platforms, and we could face legal claims that could adversely aﬀect our reputation, business, ﬁnancial condition and results of operations 14. If we or our third-party service providers experience a security breach or unauthorized parties otherwise obtain access to our customers’ data, our data or our platform, then our platform may be perceived as not secure, and our reputation may be harmed, our business operations may be disrupted, demand for our solution suites may be reduced and we may incur signiﬁcant liabilities 15. Interruptions, performance problems or defects associated with our platform could diminish our brand, subject us to liability and may adversely aﬀect our business, ﬁnancial condition and results of operations 16. We rely on the performance of, and we face stark competition for, highly skilled personnel, including our management, other key employees and qualiﬁed employees, and the loss of one or more of such personnel or of a signiﬁcant number of our team members or the inability to attract and retain executives and qualiﬁed employees we need to support our operations and growth, could harm our business 17. Our corporate culture has contributed to our success and, if we are unable to maintain it as we grow, our business, ﬁnancial condition and results of operations could be harmed 18. We rely upon third-party data centers and providers of cloud-based infrastructure to host our platform. Any disruption in the operations of these third-party providers, limitations on capacity or interference with our use could adversely aﬀect our business, ﬁnancial condition and results of operations 19.

Risk Factors 20. If our customers do not obtain necessary and requisite consents from users for us to process their personal data, we could be subject to ﬁnes and liability 21. The estimates of our market opportunity and forecasts of market growth included in our proxy statement may prove to be inaccurate, and even if the markets in which we compete achieve the forecasted growth, our business could fail to grow at a similar rate, if at all 22. The Spin-Oﬀ of the assets of our Desktop business from ironSource Ltd. prior to this oﬀering may give rise to potential liabilities for us in the event of a breach of our or our shareholders’ obligations under the agreements related to the Spin-Oﬀ or tax liabilities caused by the Spin-Oﬀ 23. Indemnity provisions in various agreements to which we are a party potentially expose us to substantial liability for infringement, misappropriation or other violation of intellectual property rights, data protection and other losses 24. Acquisitions, strategic investments, partnerships and alliances could be diﬃcult to identify, pose integration challenges, divert the attention of management, disrupt our business, dilute shareholder value and adversely aﬀect our business, ﬁnancial condition and results of operations 25. Our operations are global in scope, creating a variety of operational and regulatory challenges 26. We rely on our current understanding of regional regulatory requirements pertaining to the marketing, advertising and promotion of our solution suites, and any adverse change in such regulations, or a ﬁnding that we did not properly understand such regulations, may adversely impact our business, ﬁnancial condition and results of operations 27. We may require additional capital to support the growth of our business, and this capital might not be available on acceptable terms, if at all 28. Fluctuations in currency exchange rates could harm our operating results and ﬁnancial condition 29. Seasonality may cause ﬂuctuations in our sales and results of operations 30. Our insurance may not provide adequate levels of coverage against claims or we may be unable to ﬁnd insurance with suﬃcient coverage at a reasonable cost 31. Any legal proceedings, investigations or claims against us could be costly and time-consuming to defend and could harm our reputation regardless of the outcome Conﬁdential 58Risk Factors 20.

Risk Factors 32. Our business could be disrupted by catastrophic events 33. Our global operations may subject us to potential adverse tax consequences 34. Our SVB Credit Agreement contains ﬁnancial covenants and other restrictions on our actions that may limit our operational ﬂexibility or otherwise adversely aﬀect our results of operations 35. We are subject to rapidly changing and increasingly stringent laws, contractual obligations and industry standards relating to privacy, data protection, data security and the protection of children. The restrictions and costs imposed by these requirements, or our actual or perceived failure to comply with them, could harm our business 36. We are subject to laws and regulations worldwide, many of which are unsettled and still developing and which could increase our costs or adversely aﬀect our business 37. We are subject to anti-corruption, anti-bribery, anti-money laundering, economic and trade sanctions and similar laws, and non-compliance with such laws can subject us to criminal or civil liability and harm our business, ﬁnancial condition and results of operations 38. If we fail to adequately maintain, protect or enforce our intellectual property rights, our competitive position could be impaired and we may lose valuable assets, generate reduced revenue, and incur costly litigation to protect our rights 39. We may become subject to intellectual property disputes, which are costly and may subject us to signiﬁcant liability and increased costs of doing business 40. Our platform contains third-party open source software components, which may pose particular risks to our proprietary software, technologies and solutions in a manner that could negatively aﬀect our business 41. The dual class structure of our ordinary shares may adversely aﬀect the trading market for our Class A ordinary shares 42. The dual class structure of our ordinary shares has the eﬀect of concentrating voting power with our management and other existing shareholders, which will limit your ability to inﬂuence the outcome of important transactions, including a change in control 43. We do not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of our Class A ordinary shares Conﬁdential 59Risk Factors 32.

Risk Factors 44. We are an “emerging growth company,” and we cannot be certain if the reduced reporting and disclosure requirements applicable to emerging growth companies will make our Class A ordinary shares less attractive to investors 45. We will be a foreign private issuer and, as a result, we will not be subject to U.S. proxy rules and will be subject to Exchange Act reporting obligations that, to some extent, are more lenient and less frequent than those of a U.S. domestic public company 46. As we are a “foreign private issuer” and intend to follow certain home country corporate governance practices, our shareholders may not have the same protections aﬀorded to shareholders of companies that are subject to all NYSE corporate governance requirements Conﬁdential 60Risk Factors 44.
