Acquisition Acquisition
On June 30, 2025, we completed the acquisition of the VeloCloud business ("VeloCloud") from Broadcom for total cash consideration of $300.0 million. VeloCloud's secure, AI-optimized cloud WAN portfolio provides seamless connectivity to customer sites of any type, complementing Arista's leading data center and campus wired/wireless portfolio. The preliminary purchase price allocation based on the estimated fair values of the assets acquired and liabilities assumed as of the acquisition date, included $268.4 million of intangible assets, $148.0 million of goodwill and $116.4 million of net tangible liabilities assumed as of June 30, 2025. A portion of the goodwill is deductible for tax purposes. There was no change in the carrying value of goodwill for the three months ended March 31, 2026.
Acquisition-Related Intangible Assets
Acquisition-related intangible assets, included in other assets, are subject to amortization on a straight-line basis over their estimated useful lives, as we believe this method most closely reflects the pattern in which the economic benefits of the assets will be consumed. Acquisition-related intangible assets, excluding those that are fully amortized and no longer have economic benefit, were as follows (in millions, except years):
