Reconciliation of GAAP to Non-GAAP Measures 1 Tangible common equity divided by common shares outstanding at period-end. 2 Total revenues equal net interest income plus non-interest income. In addition to the results presented in accordance with Generally Accepted Accounting Principles (“GAAP”), this earnings presentation includes certain non-GAAP financial measures. Management believes these non-GAAP financial measures provide meaningful information to investors in understanding the Company’s operating performance and trends. These non-GAAP measures have inherent limitations and are not required to be uniformly applied and are not audited. They should not be considered in isolation or as a substitute for an analysis of results reported under GAAP. These non-GAAP measures may not be comparable to similarly titled measures reported by other companies. Reconciliations of non-GAAP/adjusted financial measures disclosed in this earnings presentation to the comparable GAAP measures are provided in the accompanying tables. 29 $ thous ands , except per s hare data Q2 2025 Q1 2025 2024 2023 2022 2021 2020 2019 2018 2017 Average assets $ 7,775,199 $ 7,451,703 $ 7,293,445 $ 6,506,614 $ 6,621,631 $ 5,724,230 $ 3,863,013 $ 2,846,959 $ 1,951,982 $ 1,524,202 Less : average intangible assets 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 Average tangible as sets $ 7,765,466 $ 7,441,970 $ 7,283,712 $ 6,496,881 $ 6,611,898 $ 5,714,497 $ 3,853,280 $ 2,837,226 $ 1,942,249 $ 1,514,469 Average equity $ 723,974 $ 738,224 $ 694,154 $ 621,006 $ 578,787 $ 413,212 $ 320,617 $ 282,604 $ 251,030 $ 133,462 Less : Average preferred equity — — — — — 4,585 5,502 5,502 5,502 5,502 Average common equity 723,974 738,224 694,154 621,006 578,787 408,627 315,115 277,102 245,528 127,960 Less: average intangible ass ets 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 Average tangible common equity $ 714,241 $ 728,491 $ 684,421 $ 611,273 $ 569,054 $ 398,894 $ 305,382 $ 267,369 $ 235,795 $ 118,227 Total assets $ 7,853,849 $ 7,616,298 $ 7,300,749 $ 7,067,672 $ 6,267,337 $ 7,116,358 $ 4,330,821 $ 3,357,572 $ 2,182,644 $ 1,759,855 Less : intangible as sets 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 Tangible assets $ 7,844,116 $ 7,606,565 $ 7,291,016 $ 7,057,939 $ 6,257,604 $ 7,106,625 $ 4,321,088 $ 3,347,839 $ 2,172,911 $ 1,750,122 Total E quity $ 722,968 $ 737,846 $ 729,827 $ 659,021 $ 575,897 $ 556,989 $ 340,787 $ 299,124 $ 264,517 $ 236,884 Less : preferred equity — — — — — — 5,502 5,502 5,502 5,502 C ommon E quity 722,968 737,846 729,827 659,021 575,897 556,989 335,285 293,622 259,015 231,382 Less : intangible as sets 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 Tangible common equity (book value) $ 713,235 $ 728,113 $ 720,094 $ 649,288 $ 566,164 $ 547,256 $ 325,552 $ 283,889 $ 249,282 $ 221,649 C ommon shares outstanding 10,421,384 11,066,234 11,197,625 11,062,729 10,949,965 10,920,569 8,295,272 8,312,918 8,217,274 8,196,310 B ook value per share (G AAP ) $ 69.37 $ 66.68 $ 65.18 $ 59.57 $ 52.59 $ 51.00 $ 40.42 $ 35.32 $ 31.52 $ 28.23 Tangible book value per share (non-G AAP )¹ $ 68.44 $ 65.80 $ 64.31 $ 58.69 $ 51.70 $ 50.11 $ 39.25 $ 34.15 $ 30.34 $ 27.04 Total R evenue (G AAP )² $ 76,270 $ 70,590 $ 276,913 $ 250,739 $ 255,751 $ 180,698 $ 141,924 $ 108,239 $ 83,177 $ 63,382 Less : Non-interest expense 43,109 42,722 173,575 131,538 148,737 87,312 74,518 59,955 43,471 32,745 Less : G ain (loss ) on sale of securities — — — — — 609 3,286 — (37) — P re-tax, pre-provision net revenue $ 33,161 $ 27,868 $ 103,338 $ 119,201 $ 107,014 $ 92,777 $ 64,120 $ 48,284 $ 39,743 $ 30,637 F or Year E nding
