We will continue to exit relationships where it makes sense for us to do so. • We plan to continue selling loans as part of our strategy to balance partner and lending limits, and manage the loan portfolio and credit quality. We retain a portion of the fee income for our role in processing transactions on sold credit card receivables with no on balance sheet risk or capital requirement. • Existing partner programs are being expanded to include new products such as lines of credit, deposit programs and credit cards. Robinhood's deposit program launched during the quarter and is having a meaningful impact to CCBX deposit growth. The expansion of these and other partner initiatives is expected to drive higher partner revenue in upcoming periods. • As we build our deposit base, we should be able to sweep deposits off and on the balance sheet as needed. This deposit sweep capability allows us to better manage liquidity and deposit programs. Fee-based business model primarily driven by: • Transaction and interchange fees • Servicing, expense recovery and other BaaS fees CCBX Partner Activity Note: Data as of and for the quarter ended December 31, 2025, unless otherwise indicated.

BaaS loan expense represents the amount paid or payable to partners for credit enhancement and servicing CCBX loans. To determine net revenue (Net BaaS loan income) earned from CCBX loan relationships, the Company takes BaaS loan interest income and deducts BaaS loan expense to arrive at Net BaaS loan income which can be compared to interest income on the Company’s community bank loans. (2) CCBX - net BaaS loan income represents BaaS loan interest income minus BaaS loan expense divided by average CCBX loans. This produces a ratio which can be compared to average yield of community bank loans. Refer to the "Non-GAAP Reconciliation" in the Appendix for more information. (3) Net interest margin, net of BaaS loan expense represents CCBX net interest income less BaaS loan expense divided by average earning assets. This produces a ratio that can be compared to net interest margin of the community bank. Refer to the "Non-GAAP Reconciliation" in the Appendix for more information.
