Patriot National Bancorp Announces Positive Fourth Quarter Results

Restructuring Strategies Return Patriot to Core Profitability; Reflects Positive Credit Quality

STAMFORD, CT—February 5, 2014—Patriot National Bancorp, Inc. (“Patriot”) (NASDAQ: PNBK), the parent company of Patriot National Bank (“the Bank”), today announced results for its fourth quarter ended December 31, 2013.

Net income for the quarter was $632,000, or $0.02 per diluted share, compared to a net loss of $1,445,000, or $0.04 loss per diluted share for the same quarter last year and a net loss of $2,370,000, or $0.06 loss per diluted share for the prior quarter ended September 30, 2013. Patriot incurred a net loss of $7.6 million or $0.20 loss per diluted share for fiscal 2013 compared to a net loss of $536,000, or $0.01 loss per diluted share for fiscal 2012. Excluding a one-time release from the loan loss allowance, gains on sales of loans, investments and branches and expenses for restructuring and prepayment penalties, the net losses were $3.5 million and $3.2 million for 2013 and 2012, respectively.

“We are pleased that fourth quarter performance positively reflects the series of restructurings strategies implemented to date. This pivotal quarter marks Patriot’s return to core earnings (earnings minus restructuring charges and prepayment penalties on borrowings) profitability. Asset quality, operations and financial metrics all improved greatly, contributing to the overall strength of the Bank”, said Michael Carrazza, Chairman of the Board. “While continuing to increase earnings, efforts are now keenly concentrated on growing assets and expanding products and services to meet the banking needs of our community.”

President’s Comments

Kenneth T. Neilson, President and CEO, commented, “We continued to execute on our business plan to build a highly profitable community bank. The initiatives put into place beginning in the first quarter of this year culminated in a profitable fourth quarter and are expected to benefit Patriot going forward. The Bank is now positioned to entertain growth opportunities.”

“We are especially pleased with the substantial improvement in asset quality. Non-accrual loans declined to $12.3 million, or 2.9% of total loans at December 31, 2013 compared to $20.7 million, or 4.8% of total loans at September 30, 2013 and $23.8 million, or 5.1% of total loans at December 31, 2012. Non-performing assets were $12.3 million at December 31, 2013 compared to $24.6 million at September 30, 2013 and $28.7 million at December 31, 2012, reflecting reductions of $12.3 million, or 50.0%, and $16.4 million, or 57.1%, respectively.”

“Our performance this quarter highlights the benefits derived from the strategies implemented. The continuance of these initiatives is Patriot’s primary goal as we focus on delivering a healthy and profitable future for our customers, employees and shareholders.”

Financial Highlights:

Asset Quality

“Our management team has made the improvement of our risk profile and the credit quality of our loan portfolio a priority” said Samuel Davis, EVP and Chief Credit Officer. “Asset quality will continue to be a high priority.”

Other real estate owned (OREO) was $4.9 million at December 31, 2012 compared to $3.8 million at September 30, 2013. As of December 31, 2013, for the first time since December 31, 2008, Patriot had no OREO properties on its balance sheet.

At December 31, 2013, the allowance for loan losses as a percentage of total loans receivable was 1.34% compared to 1.29% at the prior year-end.

Balance Sheet Review

Total assets of $540.9 million at December 31, 2013 decreased $76.9 million compared to $617.8 million at December 31, 2012. Net loans decreased by $42.2 million to $418.1 million at December 31, 2013, primarily due to Patriot dissolving its residential lending group. Premises and equipment increased by $10.8 million as a result of the Bank’s purchase of branch buildings, including a headquarter building, which had been leased previously. Ownership of these properties enables the Bank to reduce occupancy expense significantly.

Total deposits were $430.2 million at December 31, 2013, a decline of $67.1 million, or 13.5%, compared to $497.3 million at the prior year-end. These reductions were a part of our strategic effort to shrink the balance sheet to allow for repayment of higher cost borrowings while maintaining our capital ratio. In the process, the Bank reduced its total cost of deposits from 1.04% for fiscal 2012 to 0.82% for fiscal 2013 and to 0.69% for the fourth quarter of 2013.

Income Statement Review

Patriot began the disciplined and orderly implementation of its restructuring plan in March of 2013. Diverse initiatives were put into play in a deliberate and systematic manner throughout the nine month period and will continue throughout 2014. The Bank executed strategies to attain greater efficiencies and returns in the future. Some of those decisions resulted in non-core, or one-time, expenses which are reported as restructuring charges and prepayment penalties on borrowings.

In assessing Patriot’s performance, management focuses on core earnings as the indicator of the company’s profitability. For these analyses, core earnings exclude restructuring charges and prepayment penalties on borrowings. Core earnings for the twelve months ended December 31, 2013 were a loss of $3.0 million compared to core earnings of $397,000 for the twelve months ended December 31, 2012, which included a $2.4 million credit from an allowance for loan losses release and $1.2 million from the sale of investments and loans. On a core earnings basis Patriot has shown consistent improvement since the beginning of the restructuring, progressing from a net loss of $1.0 million in fourth quarter 2012 to core earnings of $292,000 for the fourth quarter of 2013.

Patriot’s fourth quarter net interest income was $4.4 million, compared to $4.0 million in the fourth quarter a year ago. Despite an increase in average yield, interest income decreased $506,000, or 8.8%, compared to the same quarter last year as a result of a decline in average interest-earning assets of $79.6 million, of which $59 million was loans. Offsetting the decline in interest income, interest expense decreased 49.4%, or $846,000, compared to 2012’s fourth quarter. This was due to a decline of $48.7 million in average interest bearing deposits coupled with a 29 basis-point decrease in their cost, and a reduction in average borrowings of $11.3 million coupled with an average rate reduction of 2.22%. For the twelve-month period ended December 31, 2013 net interest income was $16.8 million compared to $17.8 million for the same period in 2012 due to these same general factors, along with the high cost borrowings not being repaid until late in 2013.

Non-interest income was $610,000 for the fourth quarter in 2013 compared to $612,000 for the same quarter in 2012. For the twelve months ended December 31, 2013 non-interest income declined by $848,000, or 25.9%, due primarily to a $911,000 gain in 2012 on the sale of securities and a $336,000 gain on the sale of loans.

On a core operating basis, non-interest expenses declined 14.4%, or $784,000, to $4.7 million in the fourth quarter of 2013, compared to $5.5 million for the same period a year ago. Included in the current quarter non-interest expenses are $74,000 of restructuring charges associated with management’s turnaround plan and a credit of $414,000 associated with the restructuring of Patriot’s data processing services.

In 2012, the fourth quarter included a restructuring charge of $436,000. Year-to-date, core non-interest expenses decreased 6.0% to $21.6 million compared to $23.0 million for the twelve-month period in 2012.
