On May 23, 2025 (the "Purchase Date"), we completed the acquisition of Savanna Industries, Inc. ("Kudu Dynamics") for a final purchase consideration of $293 million, net of $29 million of cash acquired. The Kudu Dynamics business provides artificial intelligence enabled cyber capabilities for defense, intelligence and homeland security customers.

The preliminary goodwill recognized of $229 million represents intellectual capital and the acquired assembled workforce, neither of which qualify for recognition as a separate intangible asset. All of the goodwill recognized is tax deductible.

The following table summarizes the final fair value of intangible assets acquired at the Purchase Date and the related weighted average amortization period:

For the three and nine months ended October 3, 2025, $26 million and $38 million, respectively, of revenues related to Kudu Dynamics were recognized within the National Security & Digital reportable segment.

The following table presents changes in the carrying amount of goodwill by reportable segment:

We evaluate qualitative factors that could cause us to consider whether the estimated fair value of each of our reporting units may be lower than the carrying value, including, but not limited to (i) macroeconomic conditions, (ii) industry and market considerations, (iii) our overall financial performance, including an analysis of our current and projected cash flows, revenues and earnings, (iv) a sustained decrease in share price and (v) other relevant entity-specific events including changes in management, strategy, partners or litigation.

Program intangible assets are amortized over their respective estimated useful lives in proportion to the pattern of economic benefit based on expected future discounted cash flows. Backlog intangible assets are amortized on a straight-line basis over their estimated useful lives. Customer relationships and software and technology intangible assets are amortized either on a straight-line basis over their estimated useful lives or over their respective estimated useful lives in proportion to the pattern of economic benefit based on expected future discounted cash flows, as deemed appropriate.
