GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill

In connection with the Company’s annual goodwill impairment test as of October 31, 2025, management tested goodwill for each of its three reporting units with goodwill balances. Based on the annual goodwill impairment analysis, the Company determined that the estimated fair values of all reporting units exceeded by more than 10% their corresponding carrying values as of October 31, 2025.

As of both December 31, 2025 and 2024, accumulated goodwill impairment losses were $2,755 million, comprised of $1,568 million and $1,187 million at Ingalls and Newport News, respectively.

For the years ended December 31, 2025 and 2024, the carrying amounts of goodwill were as follows:

Other Intangible Assets

Net intangible assets consist primarily of amounts relating to acquired customer relationships and contract backlog within Mission Technologies, as well as nuclear-powered aircraft carrier and submarine program intangible assets within Newport News, with an aggregate weighted-average useful life of 28 years based on the long life cycle of the related programs. Amortization expense for the years ended December 31, 2025, 2024, and 2023, was $104 million, $109 million, and $128 million, respectively.

The Company expects amortization for currently recorded purchased intangible assets of $84 million in 2026, $62 million in 2027, $56 million in 2028, $50 million in 2029, and $41 million in 2030.

About Goodwill & Intangibles Disclosures

Goodwill and intangible asset disclosures reveal the premium paid in acquisitions and how management assesses whether that premium retains its value. Since goodwill is no longer amortized under US GAAP, the annual impairment test is the only mechanism that adjusts carrying values downward — making the assumptions behind that test critically important for investors.

Key signals: a history of goodwill impairments suggests management consistently overpays for acquisitions. Watch the gap between reporting unit fair value and carrying amount — when fair value exceeds carrying amount by less than 10-20%, a small decline in business performance could trigger a write-down. For finite-lived intangibles, examine useful life assumptions across customer relationships, technology, and trade names; aggressive estimates inflate near-term earnings. Compare total intangibles-to-total-assets ratios against peers to assess acquisition dependency. Rising goodwill as a percentage of equity can signal balance sheet fragility.
