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 B aaS 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 pr oduces 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.

34 ENVIRONMENTAL, SOCIAL AND GOVERNANCE ("ESG") INITIATIVES For Coastal, ESG is a complex initiative across the whole organization. Addressing the issue of the approximately 5.9 million un banked households (1) in the United States cannot be tackled with merely adding products or providing diversity, equity and inclusion training. Nor can re al environmental impact happen through mere board level policies and simply changing our investment portfolio. We are choosing to tackle our ESG initiative s t hroughout our company with meaningful actions and collaboration. CCBX – Working with our CCBX partners allows us to provide a broader range of services to different demographics through their offer ing s. Developing the kind of unique offerings to specific under - served or under - banked populations would be difficult for a bank our size, but by partnering with third - party fintech partners like Brigit, Greenwood and One we are able to use our banking charter to support this effort in a much broader scope. Coastal Community Bank – Our community bank has always had close ties to the communities we serve with our employees actively volunteering in those communities, and we have been recognized as a corporate philanthropist by the Puget Sound Business Journal. We are now evolvi ng to offer affiliated products through our third - party fintech partners that are more inclusive and meet their needs of a broader range of consumers. Once agai n, our scope and reach is multiplied by collaborating with our third - party fintech partners to offer inclusive products. Financial Inclusion We see financial inclusion as providing access to useful and affordable financial products and services to meet the needs of the under - served . However, overcoming a widespread distrust of banks, lack of financial education, and barriers to entry are all part of the process to bring the underserved in our communities the financial products and services they need to thrive. We are actively working to address: • Accessibility to services • Needs - based solutions • Education In collaboration with the Cities for Financial Empowerment and the Bank On national platform, this past year, a Coastal team worked to develop the Access checking product to support the financial stability of unbanked and underbanked residents in our communities by providing a safe, affordable and functional product. In January 2023, our Access checking product passed product certification and met the National Account Standards and was launched with the official Bank On certification . Climate Change Coastal is approaching our responsibility in many ways from understanding our carbon footprint and identifying potential offsets, reductions and to developing strong partnerships with ESG focused fintechs . In January 2023 we completed a Sustainable Impact Survey to understand our GHG impact and ways we can offset it. Working with our partners, we are exploring ways to develop customer facing - solutions that enable climate action and are able to participate in developing and implementing meaningful changes to help turn the tide on climate change, doing our part to help transition to a net - zero economy. Additionally, we have and will continue to consider climate change and its impact on our loan portfolio and customers.
