Altavista, VA, November 13, 2020/Globe Newswire/ - Pinnacle Bankshares Corporation (“Pinnacle” or the “Company”) (OTCQX: PPBN), the one-bank holding company for First National Bank (the “Bank”), announced today that its Board of Directors declared a cash dividend of $0.14 per share on November 10, 2020, payable December 4, 2020, to shareholders of record as of November 20, 2020.

The $0.14 per share cash dividend is equal to the $0.14 dividend paid last quarter and marks the thirty-third consecutive quarter a dividend has been declared. Pinnacle previously released its third quarter 2020 earnings on November 6, 2020.

“Pinnacle is pleased to be able to provide a consistent quarterly cash dividend of $0.14 per share to its shareholders for 2020,” stated Aubrey H. Hall, III, President and Chief Executive Officer for both the Company and the Bank. Mr. Hall further commented, “While net income through nine months of 2020 has declined as compared to the same time period of 2019, it is primarily due to higher noninterest expense associated with strategic growth initiatives including our recently completed merger with Virginia Bank Bankshares, Inc. Our current operating environment presents many challenges and uncertainties due to the negative impacts of the COVID-19 Pandemic, however, we remain pleased with Pinnacle’s overall performance and how the Company is positioned for the future.”
