C&I Healthcare Composition | June 30, 2024 Diversified CRE and C&I Healthcare Portfolio • Active in Healthcare lending since 2002. • No realized losses since 2002. No deferrals during the pandemic. • CRE – Skilled Nursing Facilities (“SNF”) – average LTV of 70%. • Highly selective regarding the quality of Skilled Nursing Operators that we finance. • Borrowers are very experienced operators that typically have in excess of 1,000 beds under management and strong cash flows. Many further supported by vertically integrated related businesses. • Loans are made primarily in “certificate of need” states which limits the supply of beds and supports stable occupancy rates. • Stabilized SNF – 65% of CRE SNF portfolio. Stabilized facilities provide cash flows adequate to support debt service and collateral value. Borrowers’ primary motive for acquisition of a stabilized property is for synergies with existing portfolio of SNFs. Average debt service coverage ratio is 1.92x. • Transitional Non-stabilized SNF – are typically value-add opportunities that may have underlying issues that can be remediated. By implementing operational and management changes, enhancing the quality of care, improving the payor mix, and optimizing efficiency, experienced operators can increase the facility's profitability and value. Operators that have a strong market share in the region can negotiate higher reimbursement rates by working with payers, such as Medicare and Medicaid, to negotiate higher reimbursement rates for the services provided by the SNF. 67% 15% 10% 4% 67% SNF 15% Ambulatory Health Care Services 10% Medical Labs 4% Misc.

Reconciliation of GAAP to Non-GAAP Measures * Tangible common equity divided by common shares outstanding at period-end. 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. 26 $ thousands, except per share data Q2 2024 2023 2022 2021 2020 2019 2018 2017 Average assets $ 7,322,480 $ 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 Average tangible assets $ 7,312,747 $ 6,496,881 $ 6,611,898 $ 5,714,497 $ 3,853,280 $ 2,837,226 $ 1,942,249 $ 1,514,469 Average equity $ 680,064 $ 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 680,064 621,006 578,787 408,627 315,115 277,102 245,528 127,960 Less: average intangible assets 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 Average tangible common equity $ 670,331 $ 611,273 $ 569,054 $ 398,894 $ 305,382 $ 267,369 $ 235,795 $ 118,227 Total assets $ 7,265,591 $ 7,067,672 $ 6,267,337 $ 7,116,358 $ 4,330,821 $ 3,357,572 $ 2,182,644 $ 1,759,855 Less: intangible assets 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 Tangible assets $ 7,255,858 $ 7,057,939 $ 6,257,604 $ 7,106,625 $ 4,321,088 $ 3,347,839 $ 2,172,911 $ 1,750,122 Total Equity $ 692,404 $ 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 Common Equity 692,404 659,021 575,897 556,989 335,285 293,622 259,015 231,382 Less: intangible assets 9,733 9,733 9,733 9,733 9,733 9,733 9,733 9,733 value) $ 682,671 $ 649,288 $ 566,164 $ 547,256 $ 325,552 $ 283,889 $ 249,282 $ 221,649 Common shares outstanding 11,192,936 11,062,729 10,949,965 10,920,569 8,295,272 8,312,918 8,217,274 8,196,310 Book value per share (GAAP) $ 61.86 $ 59.57 $ 52.59 51.00 40.42 35.32 31.52 28.23 Tangible book value per share (non-GAAP)* $ 60.99 $ 58.69 $ 51.70 50.11 39.25 34.15 30.34 27.04 Total Revenue (GAAP) $ 67,678 $ 250,739 $ 255,751 $ 180,698 $ 141,924 $ 108,239 $ 83,177 $ 63,382 Less: Gain on sale of securities - - - 609 3,286 - (37) - securities (non-GAAP) $ 67,678 $ 250,739 $ 255,751 $ 180,089 $ 138,638 $ 108,239 $ 83,214 $ 63,382 For Year Ending
