(OTCQX: FOFN) (the “Company”), the holding company for Four Oaks Bank & Trust Company (the “Bank”), today announced earnings for the third quarter and nine months ended September 30, 2017. The Company reported net income of $1.5 million or $0.22 per diluted share and $4.0 million or $0.60 per diluted share, respectively, for the third quarter and nine months ended September 30, 2017, as compared to net income of $948,000 or $0.14 per diluted share and $2.7 million or $0.40 per diluted share for the same periods in 2016. The Company recorded income tax expense of $761,000 and $2.1 million, respectively, for the three and nine months ended September 30, 2017, as compared to $633,000 and $1,594,000 for the same periods in 2016.

On June 27, 2017, the Company announced the execution of a definitive merger agreement with United Community Banks, Inc. ("United") to acquire the Company and the Bank in a stock and cash transaction. Under the terms of the agreement, the Company's shareholders will receive merger consideration consisting of 0.6178 shares of United common stock and $1.90 in cash for each share of the Company’s common stock. The transaction was unanimously approved by the Board of Directors of each company and was approved by the Company's shareholders on October 23, 2017. The transaction is expected to close on or about November 1, 2017.

President and Chief Executive Officer David H. Rupp stated, "We are pleased to report excellent third quarter results with increases in loans, deposits and earnings. This is noteworthy given that we are in the middle of preparations for our upcoming merger. Our new partners at United have spent a significant amount of time getting to know us and our operations. As we become more familiar with one another, it reaffirms our decision to join their team and deliver even better products and service to our growing markets."

Third Quarter 2017 Highlights:

• Net income growth of $510,000 or 54% compared to third quarter 2016 and $1.3 million or 50% compared to the nine months ended September 30, 2016.
• Improved net interest margin of 3.89% despite changes in market rates and pricing expectations on deposit products.
• Reductions in non-interest expenses of approximately 5% as compared to the three and nine month periods ended September 30, 2016.
• Demand, savings, and money market deposits increased $26.9 million compared to December 31, 2016 for an annualized growth rate of 10.2%.

Net Interest Margin and Net Interest Income:

Net interest margin annualized for the three and nine months ended September 30, 2017 was 3.86% and 3.89%, respectively, as compared to 3.76% and 3.73% for the same periods in 2016. Net interest income totaled $6.4 million and $19.2 million for the three and nine months ended September 30, 2017, respectively, as compared to $6.2 million and $18.2 million for the same periods in 2016.

The primary driver of the improved margins and overall net interest income for both periods was the increase in interest earned on loans and the decrease in interest expense on time deposits partially offset by a decline in interest earned on investment securities for the nine month period.

Non-Interest Income:

Non-interest income was $1.5 million and $4.5 million for the three and nine months ended September 30, 2017, respectively, as compared to $1.3 million and $4.1 million for the same periods in 2016. As the Company reviewed options to increase fee income during 2016, it invested in a new bank owned life insurance policy, which has resulted in increased fee income for the three and nine months ended September 30, 2017 of $46,000 and $172,000, respectively.

Other service charges, commissions and fees increased $53,000 and $86,000 for the three and nine months ended September 30, 2017, respectively. This increase for both periods was primarily due to increased interchange income on the debit and credit card portfolio, as well as increases in gross revenues for the Company's wealth management division. Offsetting these increases were declines in mortgage and government guaranteed lending income.

Non-Interest Expense:

Non-interest expense totaled $5.7 million and $17.5 million for the three and nine months ended September 30, 2017, respectively, as compared to $6.0 million and $18.0 million for the same periods in 2016.

The Company remained focused on expense reductions and operational efficiencies during the third quarter and, accordingly, most categories of non-interest expense declined for the three and nine months ended September 30, 2017 as compared to the preceding year. A primary contributor to the reduced expenses were declines in professional and consulting fees of $135,000 and $335,000 for the quarter and nine months ended September 30, 2017, respectively. Additionally, collections and foreclosure related expenses declined $97,000 and $259,000 for the three and nine month periods, respectively, as compared to the same periods in 2016. There were also declines for both periods in FDIC insurance, occupancy expenses, and other operating expenses.

Offsetting these declines were $135,000 and $659,000 of merger-related expenses for the three and nine months ended September 30, 2017, respectively, as the Company prepared for the proposed merger with United.

Balance Sheet:

Total assets were $726.7 million at September 30, 2017 compared to $719.9 million at December 31, 2016, an increase of $6.8 million or 0.9%. Cash, cash equivalents, and investments were $176.6 million at September 30, 2017 compared to $163.6 million at December 31, 2016, an increase of $12.9 million or 7.9%. Outstanding gross loans declined to $503.1 million at September 30, 2017 compared to $507.0 million at December 31, 2016, a decrease of $3.9 million or 0.8%. Despite the year to date decline, outstanding gross loans increased $5.3 million when compared to the linked quarter ended June 30, 2017.

Total liabilities were $653.5 million at September 30, 2017, an increase of $1.6 million or 0.2%, from $651.9 million at December 31, 2016. Total deposits increased $6.8 million or 1.2% during the nine month period ended September 30, 2017, from $553.5 million at December 31, 2016, to $560.3 million at September 30, 2017.

The Company continues to see increases in core deposits as market teams remain focused on demand, savings, and money market account growth. This total increased $26.9 million or 7.6% during the nine month period ended September 30, 2017 totaling $379.2 million compared to $352.2 million as of December 31, 2016. This growth was offset by reductions in time deposits of $20.2 million or 10.0%, which totaled $181.1 million as of September 30, 2017 compared to $201.3 million at December 31, 2016. This decline in time deposits was a result of reductions in brokered deposits of approximately $12.9 million coupled with reduced retail time deposits. Long-term borrowings were $65.0 million at September 30, 2017 compared to $70.0 million at December 31, 2016, a decrease of $5.0 million or 7.1%. Total shareholders’ equity increased $5.2 million or 7.6%, from $68.0 million at December 31, 2016, to $73.2 million at September 30, 2017.

The allowance for loan and lease losses totaled $9.4 million at September 30, 2017 compared to $9.6 million as of December 31, 2016. The allowance for loan and lease losses as a percentage of gross loans was 1.87% and 1.90% at September 30, 2017 and December 31, 2016, respectively. The Company reported a classified asset to capital ratio of 7.8% as of September 30, 2017 compared to 8.9% as of December 31, 2016.
