Exhibit 99.1

Guaranty Federal Bancshares, Inc. ANNOUNCES

Preliminary THIRD Quarter 2020 financial Results

Springfield, MO – OCTOBER 22, 2020

CEO Comments

“Many of Guaranty’s greatest accomplishments so far in 2020 were not on the ‘to-do’ list when the year started. Implementing protective equipment for the safety of our employees and customers, seamlessly transitioning to a more remote and technology driven business, issuing subordinated debt to improve our capital position, generating a significant amount of mortgages and Paycheck Protection Program (PPP) loans in a few short months, while growing deposits by over $105 million dollars are just a few examples of our 2020 activities. The buzzword of a new normal is being embraced by the Bank as we continue to adapt to virtual meetings, local health guidelines and segments of unknowns in the overall economy. The dedication and efforts by our team members as they continue to produce in this environment while maintaining a customer-first focus is why community banks, like Guaranty, are still as relevant today as they have ever been.              

Third quarter 2020 financial results include net income of $1.9 million leading to diluted earnings per share of $0.44 compared to $0.57 from the prior year quarter. This quarter included $950,000 in additional funding of the allowance for loan loss reserves in response to the current economic climate. Overall, loan modifications and deferrals have started to recede with select industries still facing difficulties as COVID-19 restrictions hamper some business models. As evidenced by interest rate cuts made by the Federal Reserve in March of this year and recent dialogue that lower interest rates will be targeted as economic uncertainty prevails, net interest margin compression has continued. The lower rate environment has significantly increased refinance activity within our loan portfolio as well as competition in our markets for nearly all loan products. Our capital position remains above all regulatory thresholds and was further bolstered during the quarter with the issuance of $20.0 million of subordinated debt by our holding company. The strong demand and attractive rate in which we were able to place this issuance shows confidence by external investors in our company. Measured growth based on conservative practices is still our focus as we support our employees, customers, shareholders and communities during the end of 2020 and beyond.”    

- Shaun A. Burke, President and Chief Executive Officer

COVID-19 Loan Modifications

Due to financial hardships caused by the COVID-19 pandemic, loan modifications were granted to borrowers across all collateral types. As of September 30, 2020, 123 loans remained modified for $110.6M (table below) for periods from one to six months. As of September 30, 2020, 46% of original modifications have resumed scheduled payments with an additional 49% projected to resume their contractual payment schedules during the fourth quarter of 2020.

Select Quarterly Financial Data

Below are selected financial results for the Company’s third quarter of 2020, compared to the second quarter of 2020 and the third quarter of 2019.

The following were items impacting the third quarter operating results as compared to the same quarter in 2019 and the financial condition results compared to December 31, 2019:

Interest income – Total interest income decreased $1.6 million (14%) during the quarter. The decrease is primarily due to declining interest rates on earning assets and our asset mix having greater percentages of cash and investment holdings rather than loans when compared to prior periods. The average balance of total interest-earning assets increased $130.1 million (14%) while the yield on average interest earning assets decreased 119 basis points to 3.74%. Compared to the third quarter of 2019, the average balance of the loan portfolio increased $27.4 million and the average loan yield decreased by 99 basis points to 4.46%. Further negatively impacting loan interest income and yield on loans was loan accretion amounts declining by $358,000 during the quarter when compared to the prior year quarter. Partially offsetting this decline in accretion income was $197,000 of loan fees recognized from the origination of PPP loans.

Interest expense - Total interest expense decreased $1.2 million (35%) during the quarter. The decrease is primarily driven by lower costs on all interest-bearing deposits and borrowings in the current low-rate environment. The average balance of interest-bearing liabilities increased $61.0 million (8%), while the average cost of interest-bearing liabilities decreased 68 basis points to 1.04%. Cuts to key interest rates by the Federal Reserve have caused significant reductions across the yield curve in 2020, however, pricing strategies by other institutions in our markets will continue to create competitive pressures on deposit rates. To fund its asset growth and maintain prudent liquidity levels going forward, the Company will continue to utilize a cost-effective mix of retail and commercial core deposits along with non-core, wholesale funding.

See the Analysis of Net Interest Income and Margin table below for the third quarter.

Asset Quality, Provision for Loan Loss Expense and Allowance for Loan Losses – The Company’s nonperforming assets increased to $11.7 million (6%) as of September 30, 2020, compared to $11.0 million as of December 31, 2019.

Based on its reserve analysis and methodology, the Company recorded $950,000 in provision for loan loss expenses during the quarter compared to $100,000 recorded during the prior year quarter. The decision to expense this amount was due to segments of our loan portfolio experiencing continued weakness as a result of COVID-19 virus related economic slowdowns and social distancing restrictions. At September 30, 2020, the allowance for loan losses of $9.7 million was 1.23% of gross loans outstanding (excluding mortgage loans held for sale), an increase from the 1.04% reserved as of December 31, 2019.

In accordance with generally accepted accounting principles for acquisition accounting, the loans acquired through a prior acquisition were recorded at fair value; therefore, there was no allowance associated with the loans at acquisition. Management continues to evaluate the allowance needed on the acquired loans factoring in the net remaining discount of approximately $625,000 as of September 30, 2020.

Management believes the allowance for loan losses is at a sufficient level to provide for loan losses in the Bank’s existing loan portfolio.

Non-interest Income – Non-interest income increased $1,333,000 (69%) during the quarter compared to the same quarter in 2019. This was primarily due to increased income from the sale of mortgage loans of $472,000 (65%), an increase in realized gains from the sale of investment securities of $267,000 (861%), an increase in income from the sale of SBA loans of $198,000 (66%), increased gains on the sale of foreclosed assets of $166,000 (124%) and income of $161,000 (100%) recognized from a new loan swap product that debuted earlier in 2020. Offsetting these items was reduced service charge income of $72,000 (16%) due to lower volume of fee-based transactions.

Non-interest Expense – Non-interest expenses increased $782,000 (11%) when compared to the same quarter in 2019. This increase was made up of several items with the following being the largest contributors:

Capital – As of September 30, 2020, stockholders’ equity increased $3.2 million (4%) to $87.8 million from $84.6 million as of December 31, 2019. Net income for the quarter exceeded dividends paid or declared by $1.2 million. The equity portion of the Company’s unrealized gains and losses related to our available-for-sale securities and interest rate swaps positively impacted equity balances by $0.7 million during the recently completed quarter. On a per common share basis, tangible book value increased to $19.42 at September 30, 2020 as compared to $18.71 as of December 31, 2019.

From a regulatory capital standpoint, all capital ratios for the Bank remain strong and above regulatory requirements.

Non-Generally Accepted Accounting Principle (GAAP) Financial Measures

In addition to the GAAP financial results presented in this press release, the Company presents non-GAAP financial measures discussed below. These non-GAAP measures are provided to enhance investors’ overall understanding of the Company’s current financial performance. Additionally, Company management believes that this presentation enables meaningful comparison of financial performance in various periods. However, the non-GAAP financial results presented should not be considered a substitute for results that are presented in a manner consistent with GAAP. A limitation of the non-GAAP financial measures presented is that the adjustments concern gains, losses or expenses that the Company does expect to continue to recognize; the adjustments of these items should not be construed as an inference that these gains or expenses are unusual, infrequent or non-recurring. Therefore, Company management believes that both GAAP measures of its financial performance and the respective non-GAAP measures should be considered together.

Operating Income

Operating income is a non-GAAP financial measure that adjusts net income for the following non-operating items:
