This Amendment No. 2 to Schedule 13D (this “Amendment”) amends and supplements the Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on June 28, 2017 (as amended by Amendment No. 1, filed with the SEC on March 6, 2018, the “Schedule 13D”), relating to the shares of common stock, par value $0.10 per share (the “Common Stock”), of Guaranty Federal Bancshares, Inc. (the “Company”). Unless specifically amended hereby, the disclosures set forth in the Schedule 13D remain unchanged.

Item 2.

Identity and Background

Item 2 of the Schedule 13D is hereby amended to remove John M. Eggemeyer, John T. Pietrzak, Mark Merlo and J. Mikesell Thomas as Reporting Persons. Following the establishment of a six-person investment committee by Castle Creek Capital V LLC (“CCC V”), the general partner of Castle Creek Capital Partners V, LP (“Fund V”), no person other than Fund V and CCC V presently has beneficial ownership (as defined in Rule 13d-3 under the Act) of the shares of Common Stock held by Fund V.

Item 4.

Purpose of Transaction

On April 1, 2022, QCR Holdings, Inc., a Delaware corporation (“QCR”), completed the previously announced acquisition of the Company pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated as of November 9, 2021, by and between the Company and QCR. Pursuant to the Merger Agreement, the Company was merged with and into QCR, with QCR surviving the merger (the “Merger”). As a result of the Merger, each share of Common Stock (including the 918,804 shares of Common Stock previously held by Fund V) was converted into the right to receive, at the election of the stockholder: (i) $30.50 in cash, (ii) 0.58775 shares of QCR common stock, or (iii) mixed consideration of $6.10 in cash and 0.4702 shares of QCR common stock, with total consideration to consist of 80% stock and 20% cash.

Following the Merger, the separate corporate existence of the Company has ceased. Accordingly, each of the Reporting Persons has no plans or proposals that relate to or would result in any of the events set forth in Items 4(a) through (j) of Schedule 13D.

Item 5.

Interest in Securities of the Issuer

Paragraphs (a), (b) and (e) of Item 5 of the Schedule 13D are hereby amended and supplemented, with effect from the date of the event giving rise to this Amendment, by replacing the text in paragraphs (a) and (b) of Item 5 of the Schedule 13D with the following:

(a) and (b)

As a result of the Merger, the Company ceased to exist, and the Reporting Persons are no longer the beneficial owners of any Common Stock.

(e)

As of April 1, 2022, the Reporting Persons ceased to be beneficial owners of more than five percent of the Common Stock.
