© 2023 Unity Technologies — 2 D E A R U N I T Y S H A R E H O L D E R S , I am pleased to address you as Unity’s CEO. I spent over a decade as Red Hat’s CEO, where we built a successful business focusing on our customers’ needs. Unity and Red Hat are both mission- driven companies committed to customer success and innovation. After a month at Unity, I believe that our key product, the Unity Engine, is unique and a foundation upon which the game industry was built. I also believe that the combination of Unity and ironSource provides us with the assets, capabilities and data to enable our customers to successfully build and scale their businesses. And I am impressed by the people at Unity, some of the brightest and most passionate in tech. This leads me to believe that we have a significant opportunity to accelerate revenue growth, improve profitability metrics and increase free cash flow generation going forward. However, we are currently doing too much, we are not achieving the synergies that exist across our portfolio, and we are not executing to our full potential. We aim to address these opportunities to emerge as a leaner, more agile, and faster growing company. We will share specifics as plans are finalized over the next few months.

© 2023 Unity Technologies — 3 $323 13% Our results in the third quarter were mixed. While revenue came in within guidance, we believe we can do better. We continued to manage costs well and beat our adjusted EBITDA guide. We delivered revenue of $544 million, within our guidance range of $540 to $550 million. This represents a 69% year-over-year increase, or 8% growth on a pro-forma basis. GAAP net loss for the quarter was reduced by half from the third quarter of the prior year to $125 million, a net loss margin of (23%). Adjusted EBITDA was strong at $131 million, above our guidance range of $90 to $100 million, resulting in a 24% adjusted EBITDA margin. Free cash flow for the quarter was $104 million.

The amounts used to calculate the pro forma percentages are consistent with disclosure required under GAAP. Such percentages are provided for illustrative purposes only and not necessarily indicative of future periods and do not give effect to the potential impact of current financial conditions, future revenues, regulatory matters, or any anticipated synergies, operating efficiencies, or cost savings that may be associated with the ironSource merger.

© 2023 Unity Technologies — 4 Create Solutions third quarter revenue of $189 million was flat year- over-year with core subscriptions up 19% excluding China. Three factors negatively impacted growth this quarter: Unity Game Services (UGS), China and Professional Services. UGS had a record third quarter last year from new game launches, China revenue declined from continued government restrictions on gaming, and we continue to reduce our reliance on Professional Services. Grow Solutions revenue of $355 million was up 166% year-over- year and 12% on a pro-forma basis. We continue to believe that we are gaining share in a relatively flat market. We experienced some revenue softness at the end of the quarter and in October from the runtime fee introduction, which is now mostly behind us. → The Runtime Fee. At the end of September, we introduced runtime fees on the Editor to complement our seat-based subscriptions, a critical step to make Create a sustainable business. While we did not expect the introduction of the fees to be easy, the execution created friction with our customers and near-term headwinds. We expect the impact of this business model change to have minimal benefit in 2024 and ramp from there as customers adopt our new releases. → Interventions to become a leaner, more agile, faster growing company. Going forward, we plan to increase our focus on our core; the Unity Editor and Runtime, and Monetization Solutions as we continue to see significant opportunities for growth in these businesses, including AI. In addition, we aim to sharpen our focus on fewer large and more attractive businesses where our capabilities offer a clear competitive advantage like Digital Twins. → Tighter integration between Create Solutions and Grow Solutions. We believe that we can create more value for our customers if we further integrate our Create and Grow organizations. We are currently capturing synergies within Grow Solutions, but not yet across businesses, which we believe presents an opportunity that is unique to Unity.

© 2023 Unity Technologies — 5 We are committed to a customer-first business model. This business model is enabled by the right product portfolio, the right initiatives and clear focus. And when executed with excellence, this business model is designed to deliver faster revenue growth, improved profitability metrics and increased free cash flow. Several weeks ago, we started a comprehensive assessment of our product portfolio to focus on those products that are most valuable to our customers. We are also evaluating the right cost structure that aligns with the more focused portfolio. We are acting quickly and expect to make final decisions over the next few weeks. We expect to start implementing the plan within this quarter and expect to complete all interventions before the end of the first quarter of 2024. This will likely include discontinuing certain product offerings, reducing our workforce, and reducing our office footprint. The exact timing of these interventions is difficult to estimate. We are therefore not providing guidance for the fourth quarter or the full year 2023. We will provide guidance for 2024 with our fourth quarter and full year 2023 results. At that time, we will also share more details on our operational interventions, which are expected to gradually improve our results. We expect 480 million of fully diluted shares at the end of the fiscal year, compared to our prior year end expectation of 488 million. We are committed to creating value for our customers and shareholders. Our success is tied to the success of creators using Unity. We are fortunate to have passionate people both inside and outside the company who share our vision. I could not be more excited to be part of this journey, and I look forward to working alongside all of you as we continue to drive Unity forward. Thank you for your trust and support. Sincerely, Jim Whitehurst Interim CEO, Unity Technologies G U I D A N C E C O N C L U D I N G T H O U G H T S

Further information on these and additional risks that could affect our results is included in our filings with the Securities and Exchange Commission (SEC), including our Quarterly Report on Form 10-Q, filed with the SEC on August 2, 2023, and our future reports that we may file with the SEC from time to time, which could cause actual results to vary from expectations. Copies of reports filed with the SEC are available on the Unity Investor Relations website. Statements herein speak only as of the date of this release, and Unity assumes no obligation to, and does not currently intend to, update any such forward-looking statements after the date of this release except as required by law. About Non-GAAP Financial Measures To supplement our consolidated financial statements prepared and presented in accordance with generally accepted accounting principles in the United States (GAAP) we use certain non-GAAP financial measures, as described below, to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe the following non-GAAP measures are useful in evaluating our operating performance. We are presenting these non- GAAP financial measures because we believe, when taken collectively, they may be helpful to investors because they

© 2023 Unity Technologies — 7 A P P E N D I X provide consistency and comparability with past financial performance. In the future, we may also exclude non- recurring expenses and other expenses that do not reflect our overall operating results. However, non-GAAP financial measures have limitations in their usefulness to investors because they have no standardized meaning prescribed by GAAP and are not prepared under any comprehensive set of accounting rules or principles. In addition, other companies, including companies in our industry, may calculate similarly-titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. As a result, our non- GAAP financial measures are presented for supplemental informational purposes only and should not be considered in isolation or as a substitute for our consolidated financial statements presented in accordance with GAAP. We define adjusted EBITDA as net income or loss excluding benefits or expenses associated with stock- based compensation, acquisitions, restructurings and reorganizations, depreciation, amortization of acquired intangible assets, interest, income tax, and other non- operating activities, which primarily consist of foreign exchange rate gains or losses. We define adjusted gross profit as GAAP gross profit excluding expenses associated with stock-based compensation, amortization of acquired intangible assets, and depreciation expense. We define non-GAAP research and development expense and non-GAAP sales and marketing expense as research and development expense and sales and marketing expense, respectively, excluding stock-based compensation expense, amortization of acquired intangible assets expense, depreciation expense, and acquisition-related costs. We define non-GAAP general and administrative expense as general and administrative expense excluding stock-based compensation expense, depreciation expense, acquisition-related costs, and restructuring and reorganization costs.
