4)	How does ironSource stand out from its competitors?

We believe that ironSource has the most comprehensive offering out there for developers; the combination of one platform with two solution suites, Sonic and Aura, places the company in the unique position of being able to offer app developers both in-app and on-device placements, which together with its additional solutions, makes it a source for core business infrastructure that app developers need to scale their businesses in the app economy today.

ironSource’s success is further demonstrated in its financials. The company has successfully combined high growth with profitability since almost day one. This combination is rare in the tech market, and having this discipline enables the company flexibility and optionality to invest in key areas without reliance on third parties to fund it.

5)	What made ironSource the right merger target for TBA?

From our first meeting with the ironSource team, it became immediately clear that we were aligned in our vision and a shared conviction about the level of long-term growth we could drive together.

ironSource is one of the fastest growing and most innovative platforms in the app economy (and in software generally) and is well-positioned for continued success as a public company. The company presents a highly unique investment opportunity with the rare combination of scale, growth and profitability – and a great, founder-led management team with a strong track record of delivering both growth and profitability through offering best-in-class technology.

ironSource will also benefit from Thoma Bravo’s financial and operational expertise in the software space and this will support the mission of creating value for developers and shareholders alike.

The management team will have full access to our platform and resources at Thoma Bravo, which has enabled us to be great partners to management in executing growth strategies. There is a big opportunity here to focus elements of the go-to-market strategy on non-game app categories as well as executing material M&A.

I’m excited for the next phase of ironSource’s growth and I’m confident that our partnership has the winning recipe for great success!
