The accompanying interim unaudited consolidated financial statements serve to update the National Bank Holdings Corporation Annual Report on Form 10-K for the year ended December 31, 2025 and include the accounts of the Company and its wholly owned subsidiaries, NBH Bank, BOJHT and 2UniFi, LLC. The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. GAAP and, where applicable, with general practices in the banking industry or guidelines prescribed by bank regulatory agencies.

GAAP requires management to make estimates that affect the reported amounts of assets, liabilities, revenues and expenses and disclosures of contingent assets and liabilities.

Because of the inherent uncertainties associated with any estimation process and future changes in market and economic conditions, it is possible that actual results could differ significantly from those estimates.

The Company’s significant accounting policies followed in the preparation of the unaudited consolidated financial statements are disclosed in note 2 of the audited financial statements and notes for the year ended December 31, 2025 and are contained in the Company’s Annual Report on Form 10-K. There have been no significant changes to the application of significant accounting policies since December 31, 2025, except for the following:

Acquisition activities—The Company accounts for business combinations under the acquisition method of accounting. Assets acquired and liabilities assumed are measured and recorded at fair value at the date of acquisition, including identifiable intangible assets. If the fair value of net assets acquired exceeds the fair value of consideration paid, a bargain purchase gain is recognized at the date of acquisition. Conversely, if the consideration paid exceeds the fair value of the net assets acquired, goodwill is recognized at the acquisition date. Fair values are subject to refinement for up to a maximum of one year after the closing date of an acquisition as information relative to closing date fair values becomes available.

The determination of the fair value of loans acquired considers credit quality and expected credit losses. Separately, an ACL is established on Day 1 through a gross-up adjustment to the amortized cost basis of the loans.

Identifiable intangible assets are recognized separately if they arise from contractual or other legal rights or if they are separable (i.e., capable of being sold, transferred, licensed, rented, or exchanged separately from the entity). The depositor relationship related to deposit liabilities, the client relationship related to assets under management, acquired technology intangibles and the trade name intangible (known as the core deposit, client relationship, acquired technology intangible assets and trade name intangible, respectively) may be exchanged in observable exchange transactions.
