Deferred Revenue

During the three and six months ended June 30, 2026, we recognized $996.9 million and $2.09 billion in revenue that was included in the deferred revenue balance as of December 31, 2025, respectively. During the three and six months ended June 30, 2025, we recognized $876.8 million and $1.85 billion in revenue that was included in the deferred revenue balance as of December 31, 2024, respectively.

Transaction Price Allocated to the Remaining Performance Obligations

As of June 30, 2026, the aggregate amount of the transaction price allocated to remaining performance obligations was $7.73 billion, which was substantially comprised of deferred security subscription and technical support services revenue as well as unbilled contract revenue from non-cancellable contracts that will be recognized in future periods. We expect to recognize approximately $3.86 billion as revenue over the next 12 months, $3.08 billion in years two and three, and the remainder thereafter.
