Business Combination, Intangible Assets, and Goodwill [Abstract] |
Business Combinations, Goodwill, and Intangible Assets | Business Combinations, Goodwill, and Intangible Assets Business Combinations In September 2024, the Company acquired all outstanding shares of WarpStream Labs, Inc. (“WarpStream Labs”), an Apache Kafka-compatible data streaming platform. The Company acquired WarpStream Labs primarily for its talent and to add WarpStream Labs’ BYOC data streaming solution to the Company’s product portfolio to serve customers who want a cloud-native streaming offering in their own cloud environment. The total purchase consideration of $135.1 million consisted of $132.5 million of cash and $2.6 million for the fair value of 132,476 shares of the Company’s Class A common stock. In allocating the purchase consideration, the Company recorded $16.9 million of cash acquired, $6.8 million as a developed technology intangible asset, to be amortized on a straight-line basis over an estimated useful life of five years, and $112.4 million of goodwill. The goodwill is primarily attributed to the assembled workforce and expected synergies arising from the acquisition, and is not deductible for income tax purposes. The Company also entered into holdback agreements with certain employees of WarpStream Labs, pursuant to which the Company issued $7.9 million in restricted Class A common stock and will pay up to an aggregate of $76.2 million in cash. The vesting and payout of the restricted common stock and holdback cash is subject to continued employment over three years and achievement of certain milestones, and is recorded as post-combination compensation expense within operating expenses over the requisite service period for accounting purposes. The Company deposited $8.6 million of the holdback cash into an escrow account upon closing of the acquisition, and the Company recorded this amount within prepaid expenses and other current assets on the consolidated balance sheets. Total compensation expense related to the holdback agreements was $29.8 million and $9.5 million for the years ended December 31, 2025 and 2024, respectively.
