Highlights

Earnings Summary

For the quarter ended March 31, 2016, the Company reported net interest income of $2.3 million compared to $2.0 million for the same period a year ago. The $293,000, or 14.5%, increase was driven by increased loan production as the Company reported average loans of $193.6 million for the three months ended March 31, 2016 compared to $155.1 million for the three months ended March 31, 2015. The increase in interest income from loans was partially offset by a $28,000, or 12.3%, decrease in interest income from securities. Also during this period, the Company’s net interest margin declined 17 basis points to 3.74%, due in part, to new loans being originated at lower yields.

Interest expense was $192,000 for the quarter, an increase of $24,000, or 14.3% as compared to the same period in 2015. The year-over-year increase resulted primarily from a 23.9%, or $34.4 million, increase in the average balance of interest-bearing deposits from the first quarter of 2015 to the first quarter of 2016.

The provision for loan loss was $134,000 in the first quarter of 2016 compared to $18,000 in the first quarter of 2015. The higher provision relates mostly to strong loan growth in the first quarter of this year as the Company originated $10.3 million in new loans during the first quarter of 2016 compared to $1.9 million in the first quarter of 2015.

For the quarter ended March 31, 2016, noninterest income increased $102,000, or 54.0%, from the same period a year ago. Mortgage banking revenue more than doubled from last year, increasing $90,000 from the first quarter of 2015 to the first quarter of 2016. Modest gains in service charges and fees on deposit accounts and gains in other income from higher merchant card services and credit card fee income also contributed to growth in noninterest income. These increases were partially offset by a $27,000 decrease in the gain on sale of securities available for sale.

For the quarter ended March 31, 2016, noninterest expense increased $387,000, or 25.9%, from the same period a year ago. Noninterest expenses were up across all categories, partially due to the opening of our Crawfordville office in September, 2015. The majority of the increase occurred in salaries and employee benefits as full-time equivalent employees increased from 47 at March 31, 2015 to 56 at March 31, 2016.

Balance Sheet

As of March 31, 2016, the Company had grown to $263.7 million in total assets, $236.9 million in deposits, and $197.3 million in portfolio net loans. This compares to $244.0 million in total assets, $217.6 million in deposits, and $187.1 million in portfolio net loans as of December 31,

2015. Growth in assets is primarily due to expansion of our loan portfolio and higher cash balances, while the $19.3 million increase in deposits is strongly connected to our opening of a third office in Crawfordville, Florida. Loan growth was strong in the first quarter across all sectors. The composition of the Bank’s loan portfolio is as follows:

Total stockholder’s equity was $25.5 million, or 9.7% of total assets at March 31, 2016, compared to $24.9 million, or 10.2% of total assets, at December 31, 2015. Book value per share increased from $12.62 at December 31, 2015 to $12.92 at March 31, 2016, with 1,976,099 common shares outstanding. Equity capital and book value per share increased in the first quarter of 2016 due to retained earnings and higher accumulated other comprehensive income, the latter of which measures unrealized holding gains or losses (net of income taxes) on investments that are classified as available for sale. As of March 31, 2016, the Bank was considered to be “well capitalized” with a Tier 1 Leverage Capital Ratio of 9.36%, a 12.25% Common Equity Tier 1 Risk-Based Capital Ratio, a 12.25% Tier 1 Risk-Based Capital Ratio, and a 13.50% Total Risk-Based Capital Ratio.

Asset Quality

Loans totaling $133,000 were deemed to be impaired under the Bank’s policy at March 31, 2016, while loans totaling $144,000 were deemed to be impaired under the Bank’s policy at December 31, 2015. At March 31, 2016, we had two non-accruing loans in the aggregate amount of $133,000, compared to two non-accruing loans totaling $137,000 at December 31, 2015. Net charge-offs totaled $2,000 for the quarter ended March 31, 2016.

Management believes that the allowance for loan and losses (“ALLL”), which was $2.6 million, or 1.31% of gross loans, at March 31, 2016 is adequate.
