NASDAQ: MNSB INVESTOR PRESENTATION Exhibit 99.2

Disclaimers This presentation contains forward-looking statements, including our expectations with respect to future events that are subject to various risks and uncertainties. The statements contained in this presentation that are not historical facts are forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. Words such as “may,” “will,” “could,” “should,” “expect,” “plan,” “project,” “intend,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “pursuant,” “target,” “continue,” and similar expressions are intended to identify such forward-looking statements. There are or will be important factors that could cause our actual results to differ materially from those indicated in these forward-looking statements, including, but not limited to, the following: the impact of developments related to the novel coronavirus (COVID-19), economic conditions, competition, inflation and market rates of interest, client relationships and changes in our organization. Factors that could cause actual results to differ materially are described in our Annual Report on Form 10-K for the year ended December 31, 2019, and in other documents subsequently filed will the Securities and Exchange Commission, available at www.sec.gov and www.mstreetbank.com. We caution readers that the list of factors is not exclusive. The forward-looking statements are made as of the date of this presentation, and we may not undertake steps to update the forward-looking statements to reflect the impact of any circumstances or events that arise after the date the forward-looking statements are made. In addition, our past results of operations are not necessarily indicative of future performance. This presentation supplements information contained in the Company’s preliminary prospectus supplement dated September 10, 2020 and should be read in conjunction therewith. Unless otherwise indicated or the context otherwise requires, all references in this presentation to “we,” “our,” “us,” and “the Company” refer to MainStreet Bancshares, Inc., and its consolidated subsidiaries, after giving effect to the reorganization transaction that was completed in July 2016, pursuant to which MainStreet Bank (the “Bank”) reorganized into a holding company structure, with each outstanding share of Bank common stock being automatically converted into and exchanged for one share of the Company’s common stock. For all periods prior to the completion of such reorganization transaction, these terms refer to the Bank and its consolidated subsidiaries, and all historical financial information included in this presentation prior to the completion of the reorganization reflect that of the Bank. The accounting and reporting policies of the Company conform to U.S. GAAP and prevailing practices in the banking industry. However, certain non-GAAP measures are used in this presentation by management to supplement the evaluation of the Company’s performance. These measures include Pre-Tax Pre-Provision (PTPP) Income, Tangible Common Equity/Tangible Assets (TCE/TA), Tangible Book Value per Share (TBVPS) and Core Net Income. Management believes that the use of these non-GAAP measures provide meaningful information about operating performance by enhancing comparability with other financial periods and other financial institutions. The non-GAAP measures used by management enhance comparability by excluding the effects of items that do not reflect ongoing operating performance, including non-recurring gains or charges, that, in management’s opinion, can distort period-to-period comparisons. These non-GAAP financial measures should not be considered an alternative to U.S. GAAP-basis financial statements, and other bank holding companies may define or calculate these or similar measures differently. A reconciliation of the non-GAAP financial measures used by the Company to evaluate and measure the Company’s performance to the most directly comparable U.S. GAAP financial measures is presented in the Appendix. 139, 141, 144 194, 134, 144 187, 175, 168 255, 230, 153 61, 174, 176 52, 165, 221 59, 166, 123 191, 191, 191 47, 82, 143
