The change was primarily due to an increase in the average balances on other borrowings, an increase in the average rates on interest-bearing deposits and a decrease in the average balance on investment securities, partially offset by an increase in the average balances and average rates on loans. The net interest margin on a tax equivalent basis was 2.79% for the three months ended March 31, 2024 compared with 2.75% for the three months ended December 31, 2023. The net interest margin on a tax equivalent basis was 2.79% for the three months ended March 31, 2024 compared with 2.93% for the same period in 2023.

Further, Prosperity believes that these non-GAAP financial measures provide useful information by excluding certain items that may not be indicative of its core operating earnings and business outlook. These non-GAAP financial measures should not be considered a substitute for, nor of greater importance than, GAAP basis financial measures and results; Prosperity strongly encourages investors to review its consolidated financial statements in their entirety and not to rely on any single financial measure. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names.
