First Quarter 1Q17 Results Summary (All comparisons are to prior quarter unless otherwise noted.) • Total loans ended the quarter at $3.0 billion and increased $92.7 million, or 13.1% annualized, driven by $196.6 million in first quarter originations. Total loans at March 31, 2017 increased $361.6 million, or 14.0%, since March 31, 2016. Fully taxable equivalent net interest income totaled $36.0 million and decreased $0.8 million, primarily due to two fewer days and a 0.02% narrowing of the net interest margin to 3.44%. Annualized net charge-offs in the non 310-30 portfolio were 0.02% of average non 310-30 loans, consistent with the prior quarter. Provision for loan losses totaled $1.8 million and increased $0.5 million due to an additional specific reserve on one energy credit. Accretable yield for the acquired loans accounted for under ASC 310-30 increased a net $5.0 million. Total deposits averaged $3.9 billion and increased $51.9 million, or 5.5% annualized, driven by transaction deposit growth of $41.4 million, or 6.3% annualized. Non-interest income totaled $8.7 million and decreased $1.3 million, driven by a $1.3 million decrease in swap-related income entirely due to interest rate movements during the quarter. Non-interest expense totaled $34.6 million and increased $0.2 million. Excluding gain on sale of OREO, non-interest expense was consistent with the prior quarter. The quarter included net problem asset workout and OREO expense of $0.8 million, representing a negative $0.02 impact to earnings per share, as no large OREO gains were realized in the quarter. Income tax benefit of $1.2 million was driven by a $2.8 million tax benefit from stock compensation activity. At March 31, 2017, common book value per share was $20.12, while tangible common book value per share was $18.05 and $18.96 after consideration of the excess accretable yield value of $0.91 per share. • • • • • • • • 15 Note: Please refer to the appendix for a reconciliation of non-GAAP financial metrics.
