The Company performs an analysis for goodwill impairment annually in the fourth quarter or more frequently as considered necessary. The Company performed a qualitative goodwill assessment in the fourth quarter of 2025, and concluded that a quantitative goodwill impairment test was not necessary as it was not more likely-than-not that the fair value of the Company’s reporting unit was below the carrying amount. Based on the analyses performed, the Company concluded that goodwill was not impaired during the periods presented.
Acquired intangible assets primarily consist of CDI, which are intangible assets arising from the purchase of deposits separately or from bank acquisitions. Refer to Note 17 - Business Combinations for additional details related to goodwill, CDI, and other intangibles related to bank acquisitions.

Changes in the Company's MSRs measured at fair value, acquired through the acquisition of VBI, were as follows for the year ended December 31, 2025:

Data and key economic assumptions, as well as the valuation's sensitivity to interest rate fluctuations, related to the Company’s MSRs as of December 31, 2025 were as follows:

Option-adjusted spread:

Estimated impact on fair value of a 100 basis point increase$(1,163)
Estimated impact on fair value of a 200 basis point increase(2,232)
Weighted-average coupon interest rate

Weighted-average servicing fee

Weighted-average remaining maturity (in months)

The sensitivity calculations above are hypothetical changes and should not be considered to be predictive of future performance. Changes in fair value based on variations in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change.

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.
