Fiscal Year 2022 Acquisition of Threat Stack, Inc.

In September 2021, the Company entered into a Merger Agreement (the “Threat Stack Merger Agreement”) with Threat Stack, Inc. ("Threat Stack"), a provider of cloud security and workload protection solutions. The transaction closed on October 1, 2021 with Threat Stack becoming a wholly-owned subsidiary of F5. The addition of Threat Stack’s cloud security capabilities to F5’s application and Application Programming Interface ("API") protection solutions is expected to enhance visibility across application infrastructure and workloads to deliver more actionable security insights for customers.

Pursuant to the Threat Stack Merger Agreement, at the effective time of the Merger, the capital stock of Threat Stack and the vested outstanding and unexercised stock options in Threat Stack were cancelled and converted to the right to receive approximately $68.9 million in cash, subject to certain adjustments and conditions set forth in the Threat Stack Merger Agreement. Transaction costs associated with the acquisition were not material.

As a result of the acquisition, the Company acquired all the assets and assumed all the liabilities of Threat Stack. The goodwill related to the Threat Stack acquisition is comprised primarily of expected synergies from combining operations and the acquired intangible assets that do not qualify for separate recognition. Goodwill related to the Threat Stack acquisition was not deductible for tax purposes. The results of operations of Threat Stack have been included in the Company's consolidated financial statements from the date of acquisition. 

The allocated purchase consideration to assets acquired and liabilities assumed based on preliminary estimated fair values is presented in the following table (in thousands):

The measurement period for the Threat Stack acquisition lapsed during the first quarter of fiscal 2023. The Company recorded immaterial adjustments to consideration exchanged for the purchase of Threat Stack within the post-close measurement period.

The developed technology intangible asset is amortized on a straight-line basis over its estimated useful life of five years and included in cost of net product revenues. The customer relationships intangible asset is amortized on a straight-line basis over its estimated useful life of five years and included in sales and marketing expenses. The weighted-average life of the amortizable intangible assets recognized from the Threat Stack acquisition was five years as of October 1, 2021, the date the transaction closed. The estimated useful lives for the acquired intangible assets were based on the expected future cash flows associated with the respective asset.
