Exhibit 99.3

SELECTED UNAUDITED PRO FORMA

CONDENSED COMBINED CONSOLIDATED FINANCIAL DATA

The following unaudited pro forma condensed combined consolidated balance sheet as of September 30, 2022 and the unaudited pro forma condensed combined consolidated statements of income for the nine months ended September 30, 2022 and for the year ended December 31, 2021 are based on the historical financial statements of Middlefield Banc Corp (“MBCN”) and Liberty Bancshares, Inc. (“Liberty”) after giving effect to the merger. The merger will be accounted for using the acquisition method of accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, “Business Combinations” (“ASC 805”).

The unaudited pro forma condensed combined consolidated statements of income for the nine months ended September 30, 2022 and for the year ended December 31, 2021 give effect to the merger as of the beginning of all periods presented. The unaudited pro forma condensed combined consolidated balance sheet as of September 30, 2022 assumed that the merger took place on September 30, 2022.

The unaudited condensed combined consolidated balance sheet and statement of income as of and for the nine months ended September 30, 2022 were derived from MBCN’s unaudited condensed financial statements and Liberty’s unaudited condensed financial statements and as of and for the nine months ended September 30, 2022. The unaudited condensed statement of income for the year ended December 31, 2021 was derived from MBCN’s and Liberty’s audited statements of income for the year ended December 31, 2021.

The pro forma condensed combined consolidated financial statements reflect management’s best estimate of the fair value of the tangible and intangible assets acquired and liabilities assumed. As final valuations are performed, increases or decreases in the fair value of assets acquired and liabilities assumed will result in adjustments, which may be material, to the balance sheet and/or statement of income.

As required, the unaudited pro forma condensed combined consolidated financial data includes adjustments which give effect to the events that are directly attributable to the merger, expected to have a continuing impact and are factually supportable. We will incur reorganization and restructuring expenses as a result of combining our companies. We also anticipate that the merger will provide the combined company with financial benefits that include reduced operating expenses (as compared to the sum of expenses from each company while operating separately) and the opportunity to earn more revenue. The pro forma information does not take into account these expected expenses or anticipated financial benefits and does not attempt to predict or suggest future results.

The unaudited pro forma condensed combined consolidated financial statements are provided for informational purposes only and are subject to a number of uncertainties and assumptions and do not purport to represent what the companies’ actual performance or financial position would have been had the merger occurred on the dates indicated and does not purport to indicate the financial position or results of operations as of any date or for any future period.
