The initial and subsequent changes in the fair value of IRLCs and the forward sales of mortgage-backed securities are recorded in mortgage income. These gains and losses were not attributable to instrument-specific credit risk. For interest rate swaps and caps, because the Company acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts substantially offset each other and do not have a material impact on its results of operations. Income (loss) for the three and nine months ended September 30, 2026, and 2025 was as follows: Three Months Ended September 30, Nine Months Ended September 30, Derivatives not designated as hedging instruments 2026 2025 2026 2025 ──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── (Dollars in thousands) Interest rate lock commitments $ (114) $ (110) $ (118) $ 55 Forward mortgage-backed securities trades 348 (26) 485 (233)

Acquisitions are an integral part of the Company’s growth strategy. All acquisitions were accounted for using the acquisition method of accounting. Accordingly, the assets and liabilities of the acquired entities were recorded at their fair values at the acquisition date. The excess of the purchase price over the estimated fair value of the net assets for tax-free acquisitions was recorded as goodwill, none of which is deductible for tax purposes. The excess of the purchase price over the estimated fair value of the net assets for taxable acquisitions was also recorded as goodwill, and is deductible for tax purposes. The identified core deposit intangibles for each acquisition are being amortized using a non-pro rata basis over an estimated life of 10 to 15 years. The results of operations for each acquisition have been included in the Company’s consolidated financial results beginning on the respective acquisition date.

the subsequent fair value adjustments that have not yet been finalized. Additionally, the Company recognized $33.8 million of core deposit intangibles as of September 30, 2026. Acquisition of Stellar Bancorp, Inc. On July 1, 2026, the Company completed the Stellar Merger. Stellar Bank operated 52 banking offices including its main office in Houston and banking offices in the Houston, Beaumont and East Texas areas and in Dallas, Texas. Pursuant to the terms of the definitive agreement, Bancshares issued 19,371,499 shares of its common stock and paid approximately $578.7 million in cash for all outstanding shares of Stellar common stock. The acquisition of Stellar constituted a business combination in accordance with FASB ASC Topic 805, Business Combinations. The assets acquired and liabilities assumed were recorded on the consolidated balance sheet at estimated fair value on the acquisition date. The determination of fair value requires management to make estimates related to discount rates, expected future cash flows, market conditions and other future events that are highly subjective in nature and subject to change. The purchase consideration allocation is considered preliminary as certain estimates related to the assets acquired and liabilities assumed are subject to continuing refinement. Valuations subject to refinement during the measurement period include, but are not limited to, loans, certain other assets, and the core deposit intangible asset. As of September 30, 2026, the following table provides the allocation of the purchase consideration to the assets acquired and liabilities assumed on the acquisition date (dollars in thousands). Fair value of purchase consideration Common stock issued (19,371,499 shares) $1,414,701 Cash 578,697 Total consideration $1,993,398 Fair value of assets acquired Cash and due from banks $681,652 Available for sale securities, at fair value 1,320,682 Loans held for investment, net 7,265,750 Bank premises and equipment, net 84,198 Other real estate owned 12,550 Core deposit intangibles 183,992 Federal Home Loan Bank and Federal Reserve Bank stock 98,939 Bank owned life insurance and other assets 237,559 Total assets acquired 9,885,322 Fair value of liabilities assumed Deposits 8,721,475 Other liabilities 57,310 Junior subordinated debentures 11,341 Total liabilities assumed 8,790,126 Fair value of net assets acquired $1,095,196 Goodwill resulting from acquisition $898,202 As of September 30, 2026, the Company recognized goodwill of $898.2 million which does not include all the subsequent fair value adjustments that have not yet been finalized. Goodwill represents the excess of the total purchase price paid over the fair value of the assets acquired, net of the fair value of liabilities assumed. The goodwill is not deductible for tax purposes. Additionally, as of September 30, 2026, total core deposit intangibles related to the Stellar Merger were $184.0 million.

Loans held for investment, net - Fair values for loans held for investment were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term, amortization status and current discount rates. Loans and leases were grouped together according to similar characteristics when applying various valuation techniques. The discount rates used for loans were based on current market rates for new originations of comparable loans and include adjustments for liquidity. The discount rate does not include a factor for credit losses as that has been included as a reduction to the estimated cash flows. For PCD loans, the initial estimate of expected credit losses is recognized in the allowance on the date of acquisition using the same methodology as other loans held-for-investment. In addition, the Company adopted ASU 2025-08 in the first quarter of 2026. Accordingly, the initial estimate of expected credit losses recognized in the allowance included both PCD and non-PCD loans which were deemed PSLs.

Core deposit intangible - The core deposit intangible represents the low cost of funding acquired core deposits provide relative to the Company’s marginal cost of funds. The fair value was estimated based on a cost savings methodology that gave consideration to expected customer attrition rates, net maintenance cost of the deposit base, interest costs associated with customer deposits, and the alternative cost of funds. The estimated fair value was grossed-up for the expected tax amortization benefit. The intangible asset is being amortized over 10 years using an accelerated method, based upon the period over which estimated economic benefits are estimated to be received.

Deposits - The fair values used for demand, savings and money market deposits are equal to the amount payable on demand at the acquisition date. The fair value of time deposits is estimated by discounting the estimated future cash flows using current rates offered for deposits with similar remaining maturities.

Read in the 10-Q

Junior subordinated debentures - The fair value of junior subordinated debentures is estimated by discounting the estimated future cash flows by using comparable corporate bond indices and swap rates from the financial services sector and factoring in the applicable credit spreads and optional early redemption provisions.

The following unaudited pro forma information presents the results of operations for the three and nine months ended September 30, 2026 and 2025 as if the Stellar Merger had occurred on January 1, 2025. The pro forma results are presented for illustrative purposes and are not intended to represent or be indicative of the actual results of operations of the merged companies that would have been achieved had the Stellar Merger occurred on January 1, 2025, nor are they intended to represent or be indicative of future results of operations. The pro forma results do not include expected operating cost savings as a result of the acquisition. These pro forma results require significant estimates and judgments particularly as they relate to valuation and accretion of income associated with acquired loans. The pro forma combined results for the three and nine months ended September 30, 2026 include merger related expenses for the Stellar Merger of $67.2 million and $67.6 million, respectively. Pro forma adjustments principally included reversing interest income as previously recorded by Stellar and recording interest income based on impact of estimated fair values of the acquired interest-earning assets and assumed interest-bearing liabilities and reversing core deposit intangible amortization as previously recorded by Stellar and recording amortization expense as it relates to the core deposit intangible recognized from the Stellar Merger.
