Epic Games seems to understand that, given Steam's massive user-base, the only way it can be a viable competitor is to have games that aren't available on Valve's service. Exclusivity deals with third-party companies cost money, and it looks like Epic Games is losing a huge amount of money to make those exclusives happen.

As spotted by PC Gamer, despite paying approximately $444 million for "minimum guarantees" on third-party games for the Epic Games Store in 2020, sales of all third-party games for the year amounted to about $265 million. Apple said that Epic Games lost about $181 million on the Epic Games Store in 2019, putting the total losses thus far at more than $300 million, should these figures be correct. Big games like Metro Exodus and Control were released first on EGS before coming to Steam later.

Apple used these figures in a statement as part of its lawsuit against Epic Games, pointing out that the service is unprofitable and is missing security features that Apple's App Store includes. It pointed out that most of Epic Games' Fortnite revenue is generated on platforms other than iOS, as well, which would seemingly mitigate the effect of the game not being available there anymore.
