NEWS RELEASE

RIVERVIEW FINANCIAL CORPORATION

REPORTS THIRD QUARTER FINANCIAL RESULTS FOR 2020

HARRISBURG, PA, October 26, 2020 / PRNEWSWIRE / Riverview Financial Corporation (the “Company” or “Riverview”) (NASDAQ: RIVE), the holding company for Riverview Bank (the “Bank”), today reported net income of $695 thousand, or $0.08 per basic and diluted weighted average common share, for the third quarter of 2020, compared to net income of $2.3 million, or $0.25 per basic and diluted weighted average common share, for the third quarter of 2019. For the nine months ended September 30, 2020, Riverview reported a net loss of $22.8 million, or $(2.46) per basic and diluted weighted average common share, compared to net income of $3.0 million, or $0.33 per basic and diluted weighted average common share, for the same period last year.

The decrease in the Company’s earnings for the three months ended September 30, 2020 as compared to the same period in 2019 was the result of an increase in the provision for loan losses coupled with the recognition of severance and furlough expenses and nonrecurring occupancy expenses. The loan loss provision increased $795 thousand comparing the three months ended September 30, 2020 and 2019. In addition, the Company recognized $579 thousand in costs associated with severance and furlough expenses related to the implementation of a cost reduction strategy aimed at substantially lowering operating costs. Also impacting third quarter 2020 results was the recognition of write downs of fair values on certain held for sale properties and the acceleration of lease payments on a closed office totaling $469 thousand.

The decrease in the Company’s earnings for the nine months ended September 30, 2020 as compared to the same period in 2019 was primarily the result of a non-cash charge related to the recognition of goodwill impairment and an increase in the provision for loan losses, both stemming from the COVID-19 pandemic. The goodwill impairment of $24.8 million had no impact on tangible book value, regulatory capital ratios, liquidity or the Company’s cash balances. For the nine months ended September 30, 2020, the provision for loan losses totaled $5.7 million compared to $2.3 million for the comparable period in 2019. The increase in the year over year provision for loan losses is the combined result of year to date 2020 organic loan growth, excluding 100% SBA guaranteed Payroll Protection Loans, and changes in qualitative factors used in our ALLL model, accounting for increased economic risks and the direct impact on our customers resulting from the COVID-19 pandemic as of September 30, 2020. As the Company continues to evaluate the impact of the COVID-19 pandemic on our overall financial performance and operations, including its effects on our loan portfolio, our provision for loan losses may increase in future periods, which could adversely affect our results of operations. The Company’s earnings were further impacted as a result of a $2.3 million reduction of net accretion on acquired assets and assumed liabilities during the nine months ended September 30, 2020, as compared to the same period last year.

The impact of these reductions was offset by the recognition of an $815 thousand net gain on the sale of investment securities in order to provide liquidity to fund loan demand and limit exposure to falling rates through the disposition of adjustable rate securities. The Company also recognized interest and fees on origination of loans pursuant to the Paycheck Protection Program (“PPP”) of $2.8 million during the nine months ended September 30, 2020. The results for the nine months ended September 30, 2019 included the first quarter recognition of $2.2 million in nonrecurring executive separation expenses along with the $456 thousand in severance charges recorded in the second quarter of 2019.

As mentioned in prior earnings releases, as well as herein, the Company began implemented cost reduction strategies beginning in 2019, and those efforts continued subsequent to the end of the second quarter of 2020 by implementing additional efficiency initiatives aimed at substantially lowering operating costs. This action implemented on September 1, 2020 is expected to lower salaries and benefits expense by $3.4 million annually on a pre-tax basis. In concert with our earlier announcement that we have suspended dividend payments until further notice, additional measures were taken to further strengthen the safety and soundness of the Bank’s capital position, support future growth, and potentially take advantage of potential strategic opportunities focused upon enhancing shareholder value, the Company completed a private placement of $25 million of 5.75% Fixed to Floating Rate Subordinated Notes, due 2030 to certain qualified institutional buyers and accredited investors subsequent to the end of the third quarter 2020.

In addition to evaluating its results of operations in accordance with accounting principles generally accepted in the United States of America (“GAAP”), Riverview routinely supplements its evaluation with an analysis of certain non-GAAP financial measures, such as tangible book value per share and return on average tangible stockholders’ equity. Riverview believes these non-GAAP financial measures provide information useful to investors in understanding its operating performance and trends. Where non-GAAP disclosures are used in this press release, a reconciliation to the comparable GAAP measures is provided in the accompanying tables. The non-GAAP financial measures Riverview uses may differ from the non-GAAP financial measures other financial institutions use to measure their results of operations.

HIGHLIGHTS

Brett D. Fulk, President and Chief Executive Officer, commented “while the ultimate impact of the Corona virus pandemic upon our customers remains largely unknown at this time, we have taken the necessary steps to bolster capital, increase our loan loss reserves, monitor credit quality, and proactively manage higher risk credit relationships. Given the aforementioned efforts I have a high degree of confidence that we will successfully manage our way through the current economic challenges we face. Furthermore, continuing improvement in our core pre-allowance for loan losses and pre-tax expenses demonstrates that our efficiency initiatives are generating the desired results.” Fulk went on to say “while reported earnings for 2020 will continue to be negatively impacted by the goodwill impairment expense taken in the second quarter of this year, I am extremely pleased that our team’s efforts are positioning Riverview for a bright future. While optimistic about the impact all our efforts are producing, I realize my optimism must remain tempered by the current pandemic and the remaining economic uncertainties faced by our economy and our industry. Therefore, our short-term goals shall remain focused on credit quality, managing our way through this current pandemic environment, and expense management.”

INCOME STATEMENT REVIEW

Tax-equivalent net interest income for the three months ended September 30, decreased to $10.5 million in 2020 from $11.4 million in 2019. The decrease in tax-equivalent net interest income was primarily attributable to a decline in the tax-equivalent loan yield and the realization of lower levels of loan accretion from purchase accounting marks established from previous M&A activity. The tax-equivalent net interest margin for the three months ended September 30, 2020, decreased to 3.26% from 4.46% for the comparable period of 2019. The tax-equivalent net interest margin, excluding income and fees earned on PPP loans, would have been 3.41% in the third quarter of 2020. The tax-equivalent yield on the loan portfolio decreased to 3.94% in the third quarter of 2020 compared to 5.67% in third quarter of 2019. The actions taken by the Federal Open Market Committee in March 2020 to reduce its target federal funds rate by 150 basis points impacted the loan portfolio yield as it had a corresponding adverse effect on our floating and adjustable rate loans. Also influencing the decline was recognizing the lower yield earned on the addition of PPP loans. The yield earned on PPP loans from interest and fees was 2.41% for the nine months ended September 30, 2020. Investments yielded 2.33% on a tax-equivalent basis in the third quarter of 2020 compared to 2.96% for the same period last year. For the three months ended September 30, the cost of deposits decreased 43 basis points to 0.56% in 2020 from 0.99% in 2019. Loans, net averaged $1.2 billion in the third quarter of 2020 and $882.6 million in the third quarter of 2019. Average investments totaled $76.9 million in 2020 and $93.0 million in 2019. Average interest-bearing liabilities increased to $1.1 billion in 2020 from $817.4 million in 2019.

For the nine months ended September 30, tax-equivalent net interest income declined $2.8 million to $29.1 million in 2020 from $31.9 million in 2019. The decrease was attributable to a reduction in the net interest margin which more than offset the increase in average earning assets. For the nine months ended September 30, tax-equivalent net interest margin was 3.37% in 2020 compared to 4.18% in 2019. The tax-equivalent net interest margin excluding purchase accounting and income and fees earned on PPP loans would have been 3.45% for the nine months ended September 30, 2020. The tax-equivalent yield on the loan portfolio decreased to 4.18% in the nine months ended September 30, 2020 compared to 5.37% for the same period in 2019. For the nine months ended September 30, investments yielded 2.69% on a tax-equivalent basis in 2020 compared to 3.06% for the same period last year. The cost of deposits decreased 29 basis points to 0.71% in the nine months ended September 30, 2020 from 1.00% for the same period in 2019. The cost of interest-bearing liabilities decreased to 0.71% in 2020 from 1.06% in 2019. Comparing the nine months ended September 30, 2020 and 2019, average earning assets increased $130.5 million which outpaced the $124.4 million increase in average interest-bearing liabilities. Loans averaged $153.4 million higher while investments averaged $25.9 million lower comparing the nine months ended September 30, 2020 and 2019. With respect to the growth in interest-bearing liabilities, deposits averaged $3.9 million more in 2020 compared to last year while average borrowing grew by more than $120.5 million comparing the two periods.

The provision for loan losses totaled $1.8 million for the quarter ended September 30, 2020, compared to $1.0 million for the same period in 2019. The provision for loan losses totaled $5.7 million for the nine months ended September 30, 2020, compared to $2.3 million for the same period in 2019. The increase in the provision for loan losses was the combined result of organic loan growth, excluding PPP loan balances outstanding, and changes in qualitative factors related to the allowance for loan losses reserve associated with increasing risks within the economy and our credit portfolio due to the effects of COVID-19, as of September 30, 2020.

For the quarter ended September 30, noninterest income totaled $2.2 million in 2020 versus $2.0 million in 2019. The increase was primarily attributable to a $250 thousand increase in mortgage banking income due to an increase in refinancing activity brought on by the reduction in mortgage interest rates. Service charges, fees and commissions decreased $30 thousand while trust and wealth management income declined $68 thousand and $6 thousand, respectively, comparing the third quarters of 2020 and 2019.

For the nine months ended September 30, noninterest income increased by $1.2 million to $7.1 million in 2020 from $5.9 million in 2019. The primary contributors to the overall increase were $815 thousand in gains on the sale of investment securities and the recognition of higher comparable mortgage banking income of $543 thousand. Offsetting the increases were reductions in trust commissions and fees and wealth management income

of $186 thousand and $73 thousand, respectively, comparing the nine months ended September 30, 2020 and 2019, which is partially driven by the impact the Corona virus pandemic has had upon equity market valuations during 2020 compared to market valuations throughout 2019. Additionally, we experienced reductions in overdraft fee income, ATM income, and reduced late charge fee income as we proactively worked with customers and noncustomers alike in an effort to minimize the financial impact of Covid-19 within the communities we serve.

Noninterest expense increased to $10.0 million for the three months ended September 30, 2020, from $9.4 million for the same period last year. The overall increase was primarily due to an increase of $179 thousand in salaries and employee benefit expenses due to nonrecurring severance and furlough costs, as well as a one-time charge of $387 thousand in net occupancy and equipment expense resulting from the closure of an office during 2019 that we have now determined to be a permanent closure. Other expenses decreased $61 thousand comparing the third quarters of 2020 and 2019 due to implementing efficiency initiatives and selective expense reductions made during the COVID-19 shutdowns within our market footprint.

For the nine months ended September 30, noninterest expense increased to $53.1 million in 2020 compared to $31.9 million for the same period in 2019. Excluding the second quarter, nonrecurring goodwill impairment charge, noninterest expense would have decreased by $3.5 million, or 11.0%, in the nine months ended 2020 as compared to the same period in 2019.

BALANCE SHEET REVIEW

Total assets, loans, net, and deposits totaled $1.4 billion, $1.2 billion, and $1.0 billion, respectively, at September 30, 2020. For the nine months ended September 30, 2020, total assets, loans and deposits increased $276.8 million, $311.3 million and $90.8 million, respectively. Business lending, including commercial and commercial real estate loans, increased $315.7 million due primarily to the addition of $273.8 million in PPP loans and originations in new and existing markets in the nine months of 2020. For this same period, construction lending increased $2.5 million while retail lending, which includes nonconforming residential mortgage, home equity and consumer loans, decreased $6.9 million. Total investments increased to $98.8 million at September 30, 2020, compared to $91.2 million at December 31, 2019 as security purchases more than offset payments and prepayments. The increase in total deposits consisted of increases in noninterest-bearing deposits of $30.8 million and interest-bearing deposits of $60.0 million. As a percentage of total deposits, noninterest-bearing deposits amounted to 17.3% at September 30, 2020 and 15.7% at December 31, 2019. Long term debt increased $210.1 million primarily through the use of the Federal Reserve’s PPPLF program, intended to provide low cost funding options to entities issuing PPP loans. For the third quarter ended September 30, 2020, total assets and deposits increased $10.0 million and $8.2 million, respectively, while loans, net, decreased $2.0 million.

Stockholders’ equity totaled $95.4 million, or $10.28 per share, at September 30, 2020, $118.1 million, or $12.81 per share, at December 31, 2019, and $117.3 million, or $12.77 per share, at September 30, 2019. The decrease in stockholders’ equity for the nine months ended September 30, 2020 was due to the goodwill impairment charge taken at the end of the second quarter of 2020. Tangible stockholders’ equity per common share increased to $10.04 at September 30, 2020, compared to $9.75 at September 30, 2019.

ASSET QUALITY REVIEW

Nonperforming assets were $13.0 million, or 1.12% of loans, net, and foreclosed assets at September 30, 2020, $13.4 million or 1.15% at June 30, 2020, and $5.1 million or 0.60% at December 31, 2019. Accruing Troubled debt restructured (“TDR”) loans increased $7.0 million from year end 2019 to $9.6 million at the end of the third quarter of 2020. In March 2020, a joint statement was issued by federal and state regulatory agencies to clarify that short-term loan modifications are not TDRs if made on a good-faith basis in response to COVID-19 to borrowers who were current prior to the implementation of our deferral programs. The Company reevaluates these credits granted deferrals under this guidance each quarter under its existing TDR framework, and where such a loan modification would meet traditional TDR concession definitions, the loan will be accounted for as a TDR. Adjusting for accruing restructured loans, nonperforming assets were $3.4 million, or 0.29% of loans, net and

foreclosed assets at September 30, 2020, and $2.4 million, or 0.28%, at December 31, 2019. The allowance for loan losses balance equaled $11.6 million, or 1.0%, of loans, net, 1.30% excluding 100% SBA guaranteed PPP loan balances outstanding, at September 30, 2020, compared to $7.5 million, or 0.88%, at December 31, 2019. The coverage ratio, the allowance for loan losses as a percentage of nonperforming assets, was 89.4% at September 30, 2020 and 148.0% at December 31, 2019. Excluding accruing restructured loans, the coverage ratio would be 346.2% at September 30, 2020. Loans charged-off, net of recoveries, equaled $1.5 million for the nine months ended September 30, 2020 and 2019.

Safe Harbor Forward-Looking Statements:

We make statements in this press release, and we may from time to time make other statements regarding our outlook or expectations for future financial or operating results and/or other matters regarding or affecting Riverview Financial Corporation, Riverview Bank, and its subsidiaries (collectively, “Riverview”) that may be considered “forward-looking statements” as defined in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements may be identified by the use of such words as “believe,” “expect,” “anticipate,” “should,” “planned,” “estimated,” “intend” and “potential.” For these statements, Riverview claims the protection of the statutory safe harbors for forward-looking statements.

Riverview cautions you that a number of important factors could cause actual results to differ materially from those currently anticipated in any forward-looking statement. Such factors include, but are not limited to: prevailing economic and political conditions, particularly in our market area; credit risk associated with our lending activities; changes in interest rates, loan demand, real estate values and competition; changes in accounting principles, policies, and guidelines; changes in any applicable law, rule, regulation or practice with respect to tax or legal issues; and other economic, competitive, governmental, regulatory and technological factors affecting Riverview’s operations, pricing, products and services and other factors that may be described in Riverview’s Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q as filed with the Securities and Exchange Commission from time to time. Most recently in December 2019, a novel strain of coronavirus surfaced in Wuhan, China, and spread around the world, with resulting business and social disruption. The coronavirus was declared a Public Health Emergency of International Concern by the World Health Organization on January 30, 2020. The risk factors associated with this event could have a material adverse effect on significant estimates, operations and business results of Riverview. Significant estimates as disclosed in Riverview’s Forms 10-K and 10-Q include allowance for loan losses, fair value of financial instruments, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loan, determination of other-than-temporary impairment losses on securities, impairment of goodwill and intangible assets.

Furthermore, the COVID-19 pandemic is having an adverse impact on the Company, its customers and the communities it serves. Given its ongoing and dynamic nature, it is difficult to predict the full impact of the COVID-19 outbreak on the Company’s business. The extent of such impact will depend on future developments, which are highly uncertain, including when the coronavirus can be controlled and abated and when and how the economy may be reopened. As the result of the COVID-19 pandemic and the related adverse local and national economic consequences, the Company could be subject to any of the following risks, any of which could have a material, adverse effect on the Company’s business, financial condition, liquidity, and results of operations: the demand for Bank’s products and services may decline, making it difficult to grow assets and income; if the economy is unable to substantially reopen, and high levels of unemployment continue for an extended period of time, loan delinquencies, problem assets, and foreclosures may increase, resulting in increased charges and reduced income; collateral for loans, especially real estate, may decline in value, which could cause loan losses to increase; the Company’s allowance for loan losses may increase if borrowers experience financial difficulties, which will adversely affect the Company’s net income; the net worth and liquidity of loan guarantors may decline, impairing their ability to honor commitments to the Company; as the result of the decline in the Federal Reserve Board’s target federal funds rate to near 0%, the yield on the Company’s assets may decline to a greater extent than the decline in the Company’s cost of interest-bearing liabilities, reducing the Company’s net interest margin and spread and reducing net income; the Company’s wealth management revenues may decline with continuing market turmoil; and the Company’s cybersecurity risks are increased as the result of an increase in the number of employees working remotely.

In addition to these risks, acquisitions and business combinations present risks other than those presented by the nature of the business acquired. Acquisitions and business combinations may be substantially more expensive to complete than originally anticipated, and the anticipated benefits may be significantly harder, or take longer, to achieve than expected. As a regulated financial institution, our pursuit of attractive acquisition and business combination opportunities could be negatively impacted by regulatory delays or other regulatory issues. Regulatory and/or legal issues related to the pre-acquisition operations of an acquired or combined business may cause reputational harm to Riverview following the acquisition or combination, and integration of the acquired or combined business with ours may result in additional future costs arising as a result of those issues.

The forward-looking statements are made as of the date of this release, and, except as may be required by applicable law or regulation, Riverview assumes no obligation to update the forward-looking statements or to update the reasons why actual results could differ from those projected in the forward-looking statements.

In addition to evaluating its results of operations in accordance with accounting principles generally accepted in the United States of America (“GAAP”), Riverview routinely presents and supplements its evaluation with an analysis of certain non-GAAP financial measures, such as tangible stockholders’ equity and Core net income ratios. The reported results for the three and nine months ended September 30, 2020 and 2019, contain items which Riverview considers non-core, namely net gains on sales of investment securities available-for-sale, acquisition related expenses and the adjustment to tax expense due to the enactment of the Tax Act. Riverview presents the non-GAAP financial measures because it believes that these measures provide useful and comparative information to assess trends in Riverview’s results of operation. Presentation of these non-GAAP financial measures is consistent with how Riverview evaluates its performance internally and these non-GAAP financial measures are frequently used by securities analysts, investors and other interested parties in evaluation of companies in Riverview’s industry. Where non-GAAP measures are used in this press release, reconciliations to the comparable GAAP measures are provided in the accompanying tables. The non-GAAP financial measures Riverview uses may differ from similarly titled non-GAAP financial measures of other financial institutions. These non-GAAP financial measures would not be considered a substitute for GAAP basis measures, and Riverview strongly encourages a review of its condensed consolidated financial statements in their entirety. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures are presented in the tabular material that follows.
