The $3.3 million in net income represents the largest net income for any one quarter in the Company’s history. Diluted earnings per share increased to $0.63 per share during the three months ended March 31, 2018 from $0.40 per share during the quarter ended March 31, 2017. Return on average equity increased to 23.6% for the three months ended March 31, 2018, up from 16.9% during the first quarter of 2017. Return on average assets was 1.82% during the current quarter, up from 1.26% during the first quarter of 2017.

“On behalf of the Board of Directors, I am very pleased to report that the Company delivered record earnings performance in the first quarter of 2018,” commented Andrew J. Ryback, director, president and chief executive officer of Plumas Bancorp and Plumas Bank. “We continued our strong performance in the first quarter by achieving increases in interest income, non-interest income, pretax income and net income. These achievements are reflective of our team’s continued hard work and dedication to meeting the needs of our clients and helping them attain their financial goals.”

Ryback added, “We are extremely proud to announce that our Company was recently recognized by two prestigious firms. First, Raymond James and Associates awarded Plumas Bancorp with the Community Bankers Cup for operating one of the top performing community banks in the country. After evaluating 272 banks and awarding 28 (the top 10%) with the Cup, we were thrilled that Plumas Bancorp ranked 5^th overall. One of the key takeaways of their analyses was our five-year stock performance. With our stock price increasing over 600%, we significantly outperformed all of the other Cup winners. Secondly, for the third consecutive year, Plumas Bank was named a ‘Super Premier’ performing bank in 2017 by the Findley Reports. This recognition was based upon multiple factors, including profitability, return on equity and loan performance. We were very pleased that our efforts are being recognized both regionally and nationally.” 

Ryback continued, “In addition to our financial news, Plumas Bank has some other news to report. April is Community Banking month and Plumas Bank is sharing the ‘Bank Local’ message throughout our footprint. Banking local creates a symbiotic relationship between community banks and the communities that they serve. Funds taken in as deposits by community banks are put to productive use by being lent back out into the local economy — to small businesses, individuals and families. By advocating for banking local, we are encouraging our clients to put their money to work in the communities that they call home. Finally, April is Financial Literacy month. Our website, plumasbank.com, offers tips on how to manage and protect your money, while our branch offices have a variety of financial materials on hand for clients and local citizens to take and share with family and friends. Our goal is to educate for financial success.”

Ryback continued, “While educating our clients and communities on financial health is a major initiative, we are also very focused on the health and well-being of our employees; for the past two years, Plumas Bank has offered a robust corporate wellness plan that provides incentives for our team members to live more active, healthy lives. Our employees have embraced the program and continue to develop fun, creative ways to challenge each other to obtain their wellness goals. And in addition to investing in their physical wellness, Plumas Bank is also investing in the financial wellness of our team by expanding our bonus plan beyond corporate officers to include all employees.”

Ryback concluded, “As we share a glimpse of what our Company is doing to create a successful environment for our employees, clients, shareholders and communities, rest assured that we are well-positioned to continue our solid financial performance and take advantage of, appropriate growth opportunities.”
