FIRST BUSEY CORP /NV/

Busey views certain non-operating items, including acquisition-related expenses, restructuring charges, and nonrecurring strategic events, as adjustments to net income reported under GAAP. We also adjust for net securities gains and losses to align with industry and research analyst reporting. The objective of our presentation of adjusted earnings and adjusted earnings metrics is to allow investors and analysts to more clearly identify quarterly trends in core earnings performance. Pre-tax non-GAAP adjustments were as follows:

1. During the nine months ended September 30, 2024, Busey executed a two-part balance sheet repositioning strategy in which it sold mortgage servicing rights on approximately $923.5 million of one-to-four family mortgage loans for a pre-tax gain of $7.7 million and sold available-for-sale debt securities with a book value of approximately $108.2 million for a pre-tax loss of $6.8 million.

2. During the nine months ended September 30, 2025, in connection with the CrossFirst acquisition, Busey’s recorded expense for the initial provision for credit losses consisting of a Day 2 provision for loan losses of $42.4 million, a Day 2 provision for unfunded commitments of $3.1 million, and an adjustment to the initial provision for unfunded commitments of $4.0 million that was recorded based on revised estimates resulting from implementation of a new CECL model.

3. Other acquisition expenses related to the acquisition of CrossFirst, which was completed on March 1, 2025, and the acquisition of M&M, which was completed on April 1, 2024.

4. Restructuring expenses were related to previously disclosed restructuring and efficiency plans.

A reconciliation of non-GAAP measures, which Busey believes facilitates the assessment of its financial results and peer comparability, is included in tabular form in this Quarterly Report. See“Item 2. Management’s Discussion and Analysis—Non-GAAP Financial Information.”
