Forward - Looking Statements and Other Information This presentation and oral statements made regarding the subject of this presentation contain forward - looking statements within the m eaning of the Private Securities Litigation Reform Act of 1995. These forward - looking statements reflect the current views of Coastal Financial Corporation (“ Coastal ”, “CFC ”, “we”, “us”, or the “Company ”) with respect to, among other things, future events and Coastal’s financial performance. Any statements about Coastal’s expectations, beliefs, plans, predictions, forecasts, objectives, assumptions or future events or performance are not historical facts and may be forward - looking. These statements ar e often, but not always, made through the use of words or phrases such as “anticipate,” “believes,” “can,” “could,” “may,” “predicts,” “potential,” “should,” “will,” “estimate,” “plans,” “projects,” “continuing,” “ongoing,” “expects,” “intends” and si milar words or phrases. Any or all of the forward - looking statements in (or conveyed orally regarding) this presentation may tur n out to be inaccurate. The inclusion of or reference to forward - looking information in this presentation should not be regarded a s a representation by Coastal or any other person that the future plans, estimates or expectations contemplated by Coastal wi ll be achieved. Coastal has based these forward - looking statements largely on its current expectations and projections about future ev ents and financial trends that Coastal believes may affect its financial condition, results of operations, business strategy and financial needs. Coastal’s actual results could differ materially from those anticipated in such forward - looking statements as a result of risks, uncertai nties and assumptions that are difficult to predict. Factors that could cause actual results to differ materially from those in the forward - looking statements include, without limitation, the risks and uncertainties discussed under “Risk Factors” in Form 10 - K for the year ended December 31, 2020, Coastal’s Quarterly Reports on Form 10 - Q, and in any of Coastal’s subsequent filings with the Securities and Exchange Commission (the “SEC”). If one or more events related to these or other risks or uncertainties materialize, or if Coastal’s underlying assumptions prove to be incorrect, actual results may differ materially from what Coastal anticipates. You are cau ti oned not to place undue reliance on forward - looking statements. Further, any forward - looking statement speaks only as of the date on which it is made and Coastal un dertakes no obligation to update or revise any forward - looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events, except as required by applicable law. This presentation includes industry and trade association data, forecasts and information that Coastal has prepared based, in pa rt, upon data, forecasts and information obtained from independent trade associations, industry publications and surveys, government agencies and other information publicly available to Coastal, which information may be specific to particular mark ets or geographic locations. Some data is also based on Coastal’s good faith estimates, which are derived from management’s knowledge of the industry and independent sources. Industry publications, surveys and forecasts generally state that the info rma tion contained therein has been obtained from sources believed to be reliable. Statements as to Coastal’s market position are based on market data currently available to Coastal. Although Coastal believes these sources are reliable, Coastal has not in dep endently verified the information contained therein. While Coastal is not aware of any misstatements regarding the industry d ata presented in this presentation, Coastal’s estimates involve risks and uncertainties and are subject to change based on various factors. Similarly, Coastal believes tha t its internal research is reliable, even though such research has not been verified by independent sources. Trademarks referred to in this presentation are the property of their respective owners, although for presentational convenie nce we may not use the ® or the TM symbols to identify such trademarks. Non - GAAP Financial Measures This presentation includes certain non - GAAP financial measures for 2017 to exclude the impact of a deferred tax asset revaluatio n due to the enactment of the Tax Cuts and Jobs Act of 2017 (the “Tax Cuts and Jobs Act”), including adjusted net income, adjusted earnings per share - diluted, adjusted return on average assets and adjusted return on average shareholders’ equity. Thes e non - GAAP financial measures and any other non - GAAP financial measures that we discuss in this presentation should not be considered in isolation, and should be considered as additions to, and not substitutes for or superior to, measures of fin anc ial performance prepared in accordance with GAAP. There are a number of limitations related to the use of these non - GAAP financial measures versus their most directly comparable GAAP equivalents. For example, other companies may calculate non - GAAP f inancial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of Coastal’s non - GAAP financial measures as tools for comparison. See the Appendix to this presentation for a reconciliation of the non - GAAP financial measures used in (or conveyed orally during) this presentation to their most directly comparable GAAP financial measures. This presentation also contains certain non - GAAP financial measures in addition to results presented in accordance with GAAP rel ating to “pre - tax, pre - provision net income” and “pre - tax, pre - provision return on average assets” to illustrate the impact of provision for loan losses and provision for income taxes on net income and return on average assets. The most directly compar abl e GAAP measure to “pre - tax, pre - provision net income” is net income. The most directly comparable GAAP measure to “pre - tax, pre - provision return on average assets” is return on average assets. See the Appendix to this presentation for a reconcili ation of the non - GAAP financial measures used in (or conveyed orally during) this presentation to their most directly comparable GAAP financial measures. This presentation also contains certain non - GAAP financial measures in addition to results presented in accordance with GAAP to illustrate and identify the impact of Paycheck Protection Program (“PPP”) loans, Paycheck Protection Program Liquidity Facility (“PPPLF”) borrowings, customer deposits from PPP loans, and related earnings and expenses. By removing these signif ica nt items and show what the results would have been without them we are providing investors with the information to better compare results with periods that did not have these significant items. "Adjusted Tier 1 leverage capital ratio, excluding PP P l oans" is a non - GAAP measure that excludes the impact of PPP loans on balance sheet. The most directly comparable GAAP measure is Tier 1 leverage capital ratio. See the Appendix to this presentation for a reconciliation of the non - GAAP financial m easures used in (or conveyed orally during) this presentation to their most directly comparable GAAP financial measures .

8 Environmental, Social and Governance (ESG) Initiatives For Coastal, ESG is a complex initiative across the whole organization. Addressing the issue of the 14.1 million unbanked people (1) in the United states cannot be tackled with merely adding products or doing diversity, equity and inclusion training. Nor can real environmental impact happen through mere board level policies and simply changing our investment portfolio. We are choosing to tackle ESG throughout our company with mea ningful actions and collaboration. CCBX – Working with our CCBX partners allows us to provide a broader range of services for different demographics through their offerings. D eve loping 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 FAIR, Brigit and Greenwood 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 and has been recognized as a corporate philanthropis t by the Puget Sound Business Journal. We are now evolving 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 again, our scope and reach is multiplied by collaborating with our third - party fintech partners to offer inclusive products. ESG Across Coastal Environmental Responsibility Social Responsibility (1) Source: National Survey of Unbanked and Underbanked Households by the Federal Deposit Insurance Corporation (FDIC) in June 2021. 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 solution • Education Climate Change Coastal is approaching our responsibility in many ways from understanding our carbon footprint and identifying offsets to developing strong partnerships with ESG focused fintechs . In 2022, we will complete a Sustainable Impact Survey with Aspiration to understand our GHG impact and ways we can offset it. Working with Aspiration, we are exploring ways to develop customer facing - solutions that enable climate action . Additionally, we have and will continue to consider climate change and its impact on our loan portfolio and customers .
