SFBS Adjusted Funding Cost Comparative Analysis Description of Analysis ▪ The following analysis was conducted in an effort to assess the value assigned by the market to ServisFirst’s branch delivery system relative to its reported cost of deposits ▪ Fundamental to the analysis is the approximation of an adjusted cost of deposits, which are inclusive of estimated expenses or “overhead” attributable to the branch delivery system, the calculation of which is predicated on the following assumptions: – Reported cost of interest bearing deposits and reported cost of total deposits for the Most Recent Quarter (MRQ) and Most Recent Year (MRY) serve as the basis for the funding costs – Reported deposit costs are adjusted to include 41.4% of reported compensation and benefits expense , and 78.2% of reported occupancy & equipment expense for the same MRQ and MRY time periods (1) ▪ In order to gauge the resulting adjusted cost of deposits relative to market valuation, the same analysis was performed across three comparable groups for purposes of comparing / contrasting ServisFirst’s position relative to peers (2) : – Southeast Peer Group: Selected Major Exchange Southeast Banks with Total Assets $5 Billion - $15 Billion – High Performing Peer Group: Selected Major Exchange Nationwide Banks with Total Assets $5 Billion - $30 Billion, TCE / TA > 8.0%, and MRQ Core ROAA > 1.65% – High Priced Peer Group: Selected Major Exchange Nationwide Banks with Total Assets $5 Billion - $30 Billion and P / TBV > 220% 28 1) Percentages derived from SFBS management’s internal analysis ; inclusive of management estimates of salary and benefits expense for deposit gathering officers, support staff, monthly core system costs, and additional support center overhead 2) Selected Peer Groups can be found on page 39

GAAP Reconciliation and Management Explanation of Non - GAAP Financial Measures 37 During the third quarter of 2019 we recorded a $1.7 million credit to our FDIC and other regulatory assessments expense as a res ult of the FDIC’s Small Bank Assessment Credit. We recorded $3.1 million of additional tax expense as a result of revaluing our net deferred tax assets at December 31, 2017 due to lower corporate income tax rates provided by the Tax Cuts and Jobs Act passed in to law in December 2017. We also recorded expenses of $347,000 related to terminating the lease agreement on our previous headquarters building in Birmingham, Alabama and expenses of moving into our new headquarters building in 2017. We recorded expenses of $2.1 million for the first quarter of 2015 related to the acquisition of Metro Bancshares, Inc. and the merger of Me tro Bank with and into the bank, and recorded an expense of $500,000 resulting from the initial funding of reserves for unfunded loan commitments for the first quarter of 2015, consistent with guidance provided in the Federal Reserve Bank’s Interagency Policy Statement SR 06 - 17. Core financial measures included in this presentation are “core net income available to common stockholders ,” “core earnings per share, basic,” “core earnings per share, diluted,” “core return on average assets,” “core return on averag e stockholders’ equity,” “core return on average common stockholders’ equity” and “core efficiency ratio.” Each of these seven co re financial measures excludes the impact of the non - routine expense attributable to the revaluing of our net deferred tax assets, lease termination, moving expenses, expenses related to the acquisition of Metro and the initial funding of reserves for unfunded l oan commitments. This presentation also contains certain non - GAAP financial measures, including Adjusted Cost of Interest - Bearing Deposits and Adjusted Cost of Total Deposits, each of which includes overhead expenses associated with managing deposit accou nts . We believe that presenting our cost of interest - bearing and total deposits including such overhead expenses relative to our peer s highlights our efficient delivery and operations of deposit products to our customers. We believe all of these non - GAAP financial measures provide useful information to management and investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP; however, we acknowledge that these non - GAAP financial measures have a number of limitations. As such, you should not view these disclosures as a substitute for results determined in accor dan ce with GAAP, and they are not necessarily comparable to non - GAAP financial measures that other companies, including those in our industry, use. The following reconciliation table provides a more detailed analysis of the non - GAAP financial measures for Sept ember 30, 2019 and the years ended December 31, 2018, 2017, 2016, 2015, and 2014. All amounts are in thousands, except share and p er share data.
