(NYSE:FCB) (the “Company”) today reported second quarter 2015 net income of $19.4 million, or $0.45 per diluted share, and record core net income of $19.0 million, or $0.44 per diluted share. Net income rose 111% year-over-year and net income per diluted share rose 76%. Core net income rose 158% year-over-year and core net income per diluted share rose 115%.

Core adjustments for the second quarter of 2015 include $0.2 million of other operating expenses and $0.8 million of gain on investment securities.

Also, we are excited to welcome to our team eight new bankers in Miami-Dade and Tampa and our masters training program candidates.”

Loan Portfolio and Composition

During the quarter, the total loan portfolio, gross of the allowance for loan losses, grew by $408.7 million to $4.5 billion at June 30, 2015, an increase of 10% from $4.1 billion as of March 31, 2015 and 39% from $3.3 billion as of June 30, 2014.

Our new loan portfolio totaled $3.8 billion as of June 30, 2015, an increase of 14% from $3.4 billion as of March 31, 2015 and 65% from $2.3 billion as of June 30, 2014. Our loan growth during the quarter was a result of $584.2 million of new loan fundings, consisting of a record $440.6 million of organic production and $143.6 million of purchased residential mortgages. Organic loan production for the quarter consisted of $122.8 million of commercial and industrial, $187.1 million of commercial real estate and $130.7 million of residential and consumer. Due to the maturation of the organic residential lending platform, the Bank does not intend to purchase additional residential mortgages in the foreseeable future.

Our acquired loan portfolio totaled $720.2 million as of June 30, 2015, a decrease of 6% from $764.6 million as of March 31, 2015 and a decrease of 25% from $957.3 million as of June 30, 2014. The decrease in the current quarter was driven by net resolution activity totaling $33.2 million as well as scheduled loan amortization. As of June 30, 2015, acquired loans made up 16% of our total loan portfolio as compared to 19% and 29% as of March 31, 2015 and June 30, 2014, respectively.

Asset Quality

The provision for loan losses of $2.5 million recorded for the second quarter of 2015 includes a $2.3 million provision for new loans and a $0.2 million provision for the acquired loan portfolio. The provision for new loans served to increase the related allowance to $19.6 million, or 0.51% of the $3.8 billion in new loans outstanding. There were no new loan portfolio charge-offs in the second quarter of 2015 and a nonperforming new loan ratio of zero percent as of June 30, 2015.

Deposits and Borrowings

Deposits totaled $4.5 billion as of June 30, 2015, an increase of 6% from $4.2 billion as of March 31, 2015 and an increase of 13% from $4.0 billion as of June 30, 2014. During the second quarter of 2015, demand deposits increased by $119.3 million, or 15%, from March 31, 2015 and increased by $475.8 million, or 109%, from June 30, 2014. Demand deposits represent 20% of total deposits as of June 30, 2015 as compared to 19% and 11% as of March 31, 2015 and June 30, 2014, respectively. The cost of deposits was 57 basis points for the quarter, representing a 2 basis point increase from the first quarter of 2015 and a 5 basis point decline from the second quarter of 2014.

Net Interest Margin and Net Interest Income

The net interest margin for the second quarter of 2015 was 3.43%, a decrease of 15 basis points from the first quarter of 2015 and an increase of 4 basis points from the second quarter of 2014. The decrease from the first quarter of 2015 was due primarily to an average balance reduction in higher yielding acquired loans of $65.7 million.

Net interest income totaled $50.2 million in the second quarter of 2015, an increase of 3% from $48.9 million in the first quarter of 2015 and an increase of 22% from $41.2 million in the second quarter of 2014. Interest income totaled $57.4 million for the second quarter of 2015, an increase of 4% from $55.4 million in the first quarter of 2015 and an increase of 18% from $48.5 million in the second quarter of 2014. Interest income from new loans increased by $2.7 million, or 10%, from the first quarter of 2015 due to continued growth in the new loan portfolio. Interest income on acquired loans decreased by $1.8 million, or 11%, from the first quarter due to expected payoffs and resolutions of acquired loans. Interest expense was $7.2 million for the second quarter of 2015, an increase of 10% from $6.6 million in the first quarter of 2015 and a decrease 1% from $7.3 million in the second quarter of 2014. The increase from the first quarter of 2015 was a result of an increase of $289.2 million of average interest-bearing liabilities coupled with increased costs associated with the addition of longer duration borrowings.

Noninterest Income and Noninterest Expense

Noninterest income (loss) totaled $14.2 million for the second quarter of 2015 as compared to ($54.1) million for the first quarter of 2015 and $6.7 million for the second quarter of 2014. The primary components of noninterest income for the quarter were loan and other fees, gain on sales of other real estate owned, income from resolution of acquired assets, and gain on investment securities of $1.9 million, $5.6 million, $2.9 million and $0.8 million, respectively. The Company continues to realize resolution of acquired asset income and gain on sales of other real estate owned stemming from its acquired asset portfolio. As a result of the early termination of the FDIC loss share agreements, the Company recognized all recoveries and gain on sales related to what were previously “covered assets” in its consolidated statement of income as these amounts are no longer shared with the FDIC.

Noninterest expense totaled $32.0 million for the second quarter of 2015, an increase of 5% from $30.7 million in the first quarter of 2015 and 4% from $30.7 million in the second quarter of 2014. For the quarter, the Company recorded non-core expenses of $0.2 million in other operating expenses associated with a branch closure and $45 thousand in professional services.

Financial Position

Capital ratios continue to be strong and well in excess of regulatory requirements. Our tangible common equity, Tier 1 leverage, and total risk-based capital ratios were 11.8%, 12.3% and 15.4% for the second quarter of 2015 respectively, compared to 12.4%, 12.6% and 16.1% for the first quarter of 2015, respectively. Stockholders’ equity totaled $857.5 million as of June 30, 2015, an increase of 1.3% from $846.8 million as of March 31, 2015 primarily driven by net income of $19.4 million which was partially offset by a $10.5 million decrease in accumulated other comprehensive income.

This release may contain “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Any statements about our expectations, beliefs, plans, strategies, predictions, forecasts, objectives or assumptions of future events or performance are not historical facts and may be forward-looking. These statements are often, but not always, made through the use of words or phrases such as “anticipates,” “believes,” “expects,” “can,” “could,” “may,” “predicts,” “potential,” “opportunity,” “should,” “will,” “estimate,” “plans,” “projects,” “continuing,” “ongoing,” “expects,” “seeks,” “intends” and similar words or phrases. Accordingly, these statements involve estimates, known and unknown risks, assumptions and uncertainties that could cause actual strategies, actions or results to differ materially from those expressed in them, and are not guarantees of timing, future results or other events or performance. Because forward-looking statements are necessarily only estimates of future strategies, actions or results, based on management’s current expectations, assumptions and estimates on the date hereof, and there can be no assurance that actual strategies, actions or results will not differ materially from expectations, you are cautioned not to place undue reliance on such statements. Additional information regarding certain risks, uncertainties and other factors that could cause actual strategies, actions and results to differ materially from those contemplated in forward-looking statements is included from time to time in our filings with the SEC, including under the heading “Risk Factors” in our recent Annual Report on Form 10-K.

Use of Non-GAAP Financial Measures

Core net income, core efficiency ratio, core return-on-assets (“core ROA”), tangible book value and tangible book value per share are each non-GAAP financial measures used in this release. A reconciliation to what we believe to be the most directly comparable GAAP financial measures - net income in the case of core net income and core ROA, total net interest income, total noninterest income and total noninterest expense in the case of core efficiency ratio, and total shareholders’ equity in the case of tangible book value and tangible book value per share - appears in tabular form at the end of this release. The Company believes each of core net income, core efficiency ratio, and core ROA is useful for both investors and management to understand the effects of certain noninterest items and provides additional perspective on the Company’s performance over time and in comparison to the Company’s competitors. Neither core net income nor core ROA should be viewed as a substitute for net income, nor should core efficiency ratio be viewed as a substitute for total net interest income, total noninterest income and total noninterest expense. The Company believes that tangible book value and tangible book value per share are useful for both investors and management, among other things, as these are measures commonly used by financial institutions, regulators and investors to measure the capital adequacy of financial institutions. The Company believes these measures facilitate comparison of the quality and composition of the Company’s capital over time and in comparison to its competitors. These measures should not be viewed as a substitute for total stockholders’ equity.

These non-GAAP measures have inherent limitations, are not required to be uniformly applied and are not audited. They should not be considered in isolation or as a substitute for financial results and analyses of results reported under GAAP, and should be read in conjunction with the Company’s financial statements prepared in accordance with GAAP. These non-GAAP measures may not be comparable to similarly titled measures reported by other companies.
