GOODWILL AND INTANGIBLE ASSETS
Due to the application of pushdown accounting, the Company’s consolidated balance sheet included goodwill and intangible assets recognized by Illumina in connection with Illumina’s acquisition of the Company.
Goodwill Impairment
Goodwill represented the excess of purchase price Illumina paid over the fair value of the net identifiable assets acquired upon the Acquisition of the Company.

2023 Goodwill Impairment
In Q3 2023, Illumina concluded the sustained decrease in Illumina’s stock price and overall market capitalization during the quarter was a triggering event indicating the fair value of GRAIL might be less than its carrying amount which led the Company to test goodwill for impairment. The assessment was performed using a combination of both an income and a market approach to determine the fair value of goodwill. The income approach utilized estimated discounted cash flows, while the market approach utilized comparable company information. Estimates and assumptions used in the income approach included projected cash flows and a discount rate. The discount rate selected at the time of the goodwill impairment assessment was 24.0%. The Company recognized a goodwill impairment of $608.5 as a result of the impairment assessment, primarily due to changes to expected timing of revenue and a higher discount rate selected for the fair value calculation of GRAIL.
2024 Goodwill Impairment
In Q2 2024, prior to the Spin-Off, the approval of the Spin-Off by Illumina’s board of directors represented a potential indicator of impairment, which also aligned with the timing of Illumina’s annual goodwill impairment test date for 2024. The assessment was performed using a market approach to determine the fair value of goodwill which utilized the valuation ranges prepared by the divestment financial advisors engaged by Illumina in connection with the Spin-Off. The valuation ranges were determined using revenue multiples from public company peers for 2024 and 2025. The implied discount rate for the goodwill impairment assessment was 51.5%. The Company recognized a goodwill impairment of $888.9 as a result of the impairment assessment, primarily due to changes to the forecast of GRAIL’s value and the method for valuing GRAIL.
These estimates and assumptions in each of the evaluations described above represent a Level 3 measurement because they include unobservable inputs that are supported by little or no market activity and reflect Company-determined and judgmental factors for these assumptions in measuring fair value. The assumptions in the assessment of an impairment analysis are inherently subjective due to uncertainty and any slight changes in these rates and assumptions could have a significant impact on the concluded value of goodwill.
Intangible Assets
Intangible assets identified in connection with Illumina’s acquisition of the Company include developed technology, trade names and IPR&D and were measured at fair value as of the Closing Date.

In conjunction with the Q3 2023 goodwill impairment assessment described above, the Company also evaluated the IPR&D intangible asset for potential impairment. The evaluation for a potential impairment of the IPR&D intangible asset was performed by comparing its carrying value to the assessed estimated fair value, which was determined by the income approach, using a discounted cash flow model. Estimates and assumptions used in the income approach included projected cash flows and a discount rate. The discount rate selected at the time of the IPR&D intangible impairment assessment was 19.0%. Based on the impairment test performed, the Company assessed and determined that the carrying value of the IPR&D intangible asset exceeded its estimated fair value. As a result, the Company recognized an impairment of $110.0 million, primarily due to a decrease in projected cash flows and a higher discount rate selected for the fair value calculation.
In conjunction with Illumina’s Q2 2024 goodwill impairment assessment, the IPR&D intangible asset of the GRAIL reporting unit was evaluated for potential impairment by Illumina prior to the Spin-Off. The evaluation for a potential impairment of the IPR&D intangible asset was performed by comparing its carrying value to the assessed estimated fair value, which was determined by the income approach, using a discounted cash flow model. Estimates and assumptions used in the income approach included projected cash flows and a discount rate. The discount rate selected at the time of the IPR&D intangible impairment assessment was 46.5%. Based on the impairment test performed, Illumina assessed and determined that the carrying value of GRAIL’s IPR&D intangible asset exceeded its estimated fair value. As a result of push down accounting, the Company recognized an impairment of $420.0 million primarily due to changes to revenue projections and the discount rate utilized.
In Q2 2024, subsequent to the Spin-Off, the Company performed a portfolio review and determined to decrease investment in the development of the IPR&D asset, which impacted the amount and timing of expected future cash flows attributable to IPR&D. This determination was driven by the impact of the Company’s post-Spin-Off capital structure, constitution of the Company’s Board at the time of the Spin-Off as the key decision maker for the determination, and increased ability to revisit the Company’s business strategy and portfolio as a standalone public company without regulatory oversight. This represented a potential impairment indicator. An impairment assessment was performed using a discounted cash flow model utilizing the updated projected cash flows and discount rate. The discount rate selected was 20.0%. Based on the impairment test performed, the Company assessed and determined that the carrying value of the IPR&D intangible asset exceeded its estimated fair value. As a result, the Company recognized an additional impairment of $112.0 million, primarily due to a decrease in projected cash flows.
In Q2 2025, the Company identified a change in market conditions in relation to its IPR&D asset which is in development. The change is expected to impact the amount of future cash flows attributable to the technology underlying the IPR&D asset. This represented a potential impairment indicator. An impairment assessment was performed using a discounted cash flow model utilizing the updated projected cash flows and discount rate. The discount rate selected was 21.0%. Based on the impairment test performed, the Company assessed and determined that the carrying value of the IPR&D intangible asset exceeded its estimated fair value. As a result, the Company recognized an impairment of $28.0 million, resulting in the write off of the entire carrying value of the IPR&D asset.
The estimates and assumptions updated in each of the evaluations described above represent a Level 3 measurement because they include unobservable inputs that are supported by little or no market activity and reflect Company-determined and judgmental factors for these assumptions in measuring a fair value. The assumptions in the assessment of an impairment analysis are inherently subjective due to uncertainty and any slight changes in these rates and assumptions could have a significant impact on the concluded value of the Goodwill and IPR&D intangible assets.
During 2024, the Company performed a recoverability test of its finite-lived intangible assets, and no impairment was identified. In 2025, the Company determined that no triggering events occurred that would require performing a recoverability test, and accordingly, no impairment charge was recorded. See Note 17, Subsequent Events, for information regarding a possible impairment indicator related to the Company’s finite-lived intangible assets identified during the three months ending March 31, 2026.
Amortization expense related to finite-lived intangible assets was $138.3 million for each of the years ended December 31, 2025, December 31, 2024, and December 31, 2023.
The estimated future annual amortization of finite-lived intangible assets is shown in the following table. Actual amortization expense to be reported in future periods could differ from these estimates as a result of acquisitions, divestitures, and asset impairments, among other factors.

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.
