Our commitments associated with outstanding commitments to extend credit and standby and commercial letters of credit are summarized in the following table. Since commitments associated with commitments to extend credit and commercial and standby letters of credit may expire unused, the amounts shown do not necessarily reflect the actual future cash funding requirements.

As of September 30, 2026, we had $2.74 billion in commitments to extend credit for on-balance sheet loans, compared to $2.31 billion as of December 31, 2025. The $432.8 million increase is largely attributed to an increase of $136.8 million in consumer and other loan commitments, related to CCBX, a $127.8 million increase in credit cards, related to CCBX, a $125.8 million increase in residential real estate commitments, related to CCBX and a $53.4 million increase in commercial and industrial capital call line commitments, also related to CCBX, partially offset by a $40.0 million decrease in commercial construction loans.

As of September 30, 2026, commitments associated with sold credit card receivables subject to receivable sale agreements totaled $7.78 billion, compared to $4.17 billion as of December 31, 2025. While we retain the customer account relationship, subsequent receivables generated by these customer accounts are sold to BaaS partners pursuant to the applicable receivable sale agreements and remain subject to the Company's established partner and portfolio limits.

These limits allow us to manage portfolio size by partner and by loan category.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commercial and industrial loan commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. For community bank lending, we evaluate each borrower's creditworthiness on a case-by-case basis. The amount of collateral obtained, if considered necessary by us, upon extension of credit, is based on management’s credit evaluation of the customer. The type of collateral held varies but may include accounts receivable, inventory, property and equipment, and income-producing commercial properties. For CCBX lending programs, loans are originated in accordance with Bank-approved underwriting criteria established for each partner program and are subject to contractual terms and ongoing oversight and monitoring by the Bank.

Standby and commercial letters of credit are conditional commitments issued by us to guarantee the performance of a customer to a third party. In the event of nonperformance by the customer, we have rights to the underlying collateral, which can include commercial real estate, physical plant and property, inventory, receivables, cash and/or marketable securities. Our credit risk associated with issuing letters of credit is essentially the same as the risk involved in extending loan facilities to our customers. No losses were incurred in 2026 or 2025 under these commitments.

On October 2, 2026, Allegheny County Employees’ Retirement System filed a putative securities class action complaint captioned Allegheny County Employees’ Retirement System v. Coastal Financial Corp., et al., Civ. No. 2:26-3756, in the United States District Court for the Western District of Washington against the Company and certain of its current and former officers. The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder, and purports to assert a class action on behalf of purchasers of Company securities between October 28, 2024 and July 29, 2026. The complaint alleges, among other things, that the defendants made false statements and omissions about the Company’s CCBX business, including its credit quality and related risk management practices. The named plaintiff seeks unspecified damages, fees, interest, and costs. On October 19, 2026, a shareholder derivative suit entitled Moore v. Adams, et al., Civ. No. 2:26-3982, was filed in the United States District Court for the Western District of Washington against certain of the Company’s current and former officers and directors, and against the Company as nominal defendant. The suit avers purported breach of fiduciary duty and unjust enrichment claims based on the same alleged wrongdoing as the first lawsuit described above. These actions are in their preliminary stages, the outcomes remain uncertain and the Company cannot predict the potential impact, if any, on its business, operations and/or financial condition at this time. The Company intends to vigorously defend against the allegations in the complaints.
