TEL AVIV, Israel, and SAN FRANCISCO, May 4, 2021 ironSource, a leading business platform for the app economy and Thoma Bravo Advantage (NYSE: TBA), today announced financial results for the three months ended March 31, 2021.

“This was a record quarter for ironSource. In addition to signing an agreement to go public through a merger with Thoma Bravo Advantage, we achieved very strong first-quarter results, with 96% year-over-year revenue growth, and a dollar-based net expansion rate of 176%,” said Tomer Bar Zeev, CEO and co-founder of ironSource. “These results are a testament to the strength of our platform and the value it provides to our customers across the app economy. The strong top line growth and high profitability are consistent with our robust historical performance, and speak to our ability to generate shareholder value as we become a public company.”

First Quarter 2021 Financial and Corporate Highlights:

•

Total revenue of $119.7 million, up 96% year-over-year

•

Adjusted EBITDA of $39.5 million

•

Adjusted EBITDA margin of 33%

•

Net Income of $10.2M

•

Dollar-based net expansion rate of 176%, compared to an average of 148% for the prior 8 quarters, with the increase driven by new solutions and products released in 2020, which increased the value the ironSource platform provides to customers

•

292 customers each contributing more than $100,000 of revenue in the trailing 12 months, representing 94% of total revenue for the period

•

Gross retention rate of 99% for ironSource’s customers who generated over $100,000 of revenue over the trailing 12-month period

•

Built out the ironSource platform offering for app developers with the acquisitions of Soomla, which provides advertising analytics, and Luna Labs, which provides automated creative production tools. While they added meaningful value to our platform offering, the contribution of these acquisitions to our first quarter financial results was immaterial.

Combination with Thoma Bravo Advantage:

As previously announced, ironSource is combining with Thoma Bravo Advantage (NYSE: TBA) (“TBA”), a publicly-traded special purpose acquisition company, to bring to the public markets a high-growth, highly-profitable and scalable business that provides a comprehensive business platform for app developers. As a public company, ironSource is expected to benefit from the financial and operational support of Thoma Bravo – one of the most experienced and successful software investors in the world. With a track record of over 300 software investments, Thoma Bravo can provide ironSource with unparalleled industry expertise and a global network.

Further information about ironSource and its full first quarter fiscal year 2021 results can be found in the registration statement on Form F-4 and preliminary proxy statement/prospectus contained therein filed today with the SEC.

While the registration statement has not yet become effective and the information contained therein is subject to change, it provides important information about ironSource and Thoma Bravo Advantage, as well as the proposed business combination.

Key Metrics and Non-GAAP Financial Measures

ironSource monitors the key business metrics set forth below to help evaluate the business and growth trends, establish budgets, measure the effectiveness of sales and marketing efforts, and assess operational efficiencies. The calculation of the key metrics discussed below may differ from other similarly titled metrics used by other companies, securities analysts or investors.

Customers Contributing More than $100,000 of Revenue

ironSource’s larger customer relationships drive scale, improved unit economics and operating leverage in our business model, which improves its solutions and thereby increases its value proposition to all of ironSource’s customers. To measure ironSource’s ability to scale with its customers and attract large enterprises to its platform, ironSource counts the number of customers that contributed more than $100,000 in revenue in the trailing 12 months. ironSource’s gross customer retention rate is calculated by comparing two twelve month periods to see how many customers in the previous period remain active customers in the current period. ironSource’s customer count is subject to adjustments for acquisitions, consolidations, spin-offs and other market activity.

Dollar-Based Net Expansion Rate

ironSource believes the growth in the use of its platform by existing customers is an important measure of the health of its business and future growth prospects. ironSource monitors its performance in this area using an indicator management refers to as dollar-based net expansion rate. ironSource calculates dollar-based net expansion rate for a period by dividing current period revenue from a set of customers by prior period revenue of the same set of customers. Prior period revenue is the trailing 12-month revenue measured as of such prior period end. Current period revenue is the trailing 12-month revenue from the same customers as of the current period end. Management’s calculation of dollar-based net expansion rate includes the effect of any customer renewals, expansion, contraction and churn, but excludes revenue from new customers.

Adjusted EBITDA and Adjusted EBITDA Margin

ironSource defines Adjusted EBITDA as income from continuing operations, net of income taxes, as adjusted for income taxes, financial expenses, net and depreciation and amortization, further adjusted for assets impairment, share-based compensation expense and fair value adjustment related to contingent consideration. ironSource defines Adjusted EBITDA Margin as Adjusted EBITDA calculated as a percentage of revenue. Adjusted EBITDA and Adjusted EBITDA Margin are included in this press release because they are key metrics used by management and our board of directors to assess our financial performance. Adjusted EBITDA and Adjusted EBITDA Margin are frequently used by analysts, investors and other interested parties to evaluate companies in our industry. ironSource management believes that Adjusted EBITDA and Adjusted EBITDA Margin are appropriate measures of operating performance because each eliminates the impact of expenses that do not relate directly to the performance of the underlying business.

Adjusted EBITDA and Adjusted EBITDA Margin are not GAAP measures of our financial performance or liquidity and should not be considered as alternatives to net loss as a measure of financial performance, as alternatives to cash flows from operations as a measure of liquidity, or as alternatives to any other performance measure derived in accordance with GAAP. Adjusted EBITDA and Adjusted EBITDA Margin should not be construed as inferences that our future results will be unaffected by unusual or other items. Additionally, Adjusted EBITDA and Adjusted EBITDA Margin are not intended to be measures of free cash flow for management’s discretionary use, as they do not reflect our tax payments and certain other cash costs that may recur in the future, including, among other things, cash requirements for costs to replace assets being depreciated and amortized. Management compensates for these limitations by relying on our GAAP results in addition to using Adjusted EBITDA and Adjusted EBITDA Margin as supplemental measures. Our measures of Adjusted EBITDA and Adjusted EBITDA Margin are not necessarily comparable to similarly titled captions of other companies due to different methods of calculation.
