Kent Ellert, Chief Executive Officer and President of FCB Financial Holdings, Inc., commented, “This was another record quarter for our Company, highlighted by new loan and deposit growth in excess of $450 million. This continued momentum across our fundamental core businesses is creating a foundation for sustainable growth and producing strong financial results within a framework of safety and soundness.”

Loan Portfolio and Composition

During the quarter, the total loan portfolio, gross of the allowance for loan losses, grew by $450.5 million to $5.6 billion at March 31, 2016, an increase of 9% from $5.2 billion as of December 31, 2015 and 37% from $4.1 billion as of March 31, 2015.

The Bank’s new loan portfolio totaled $5.1 billion as of March 31, 2016, an increase of 11% from $4.6 billion as of December 31, 2015 and 52% from $3.4 billion as of March 31, 2015. Loan growth during the quarter was a result of $512.1 million of new loan fundings, consisting of $327.3 million of organic production and $184.7 million of purchased residential mortgages. Organic loan production for the quarter consisted of $134.8 million of commercial and industrial, $76.0 million of commercial real estate and $116.5 million of residential and consumer. As the acquired portfolio continues to resolve, the Bank may periodically supplement organic production with high quality purchased residential mortgages as part of its overall balance sheet management strategy. As of March 31, 2016 new loans made up 91% of the total loan portfolio as compared to 89% and 81% as of December 31, 2015 and March 31, 2015, respectively.

The Bank’s acquired loan portfolio totaled $535.1 million as of March 31, 2016, a decrease of 8% from $582.4 million as of December 31, 2015 and a decrease of 30% from $764.6 million as of March 31, 2015. The decrease in

the current quarter was driven by the resolution of $31.4 million of loans as well as scheduled loan amortization. As of March 31, 2016, acquired loans made up 9% of our total loan portfolio as compared to 11% and 19% as of December 31, 2015 and March 31, 2015, respectively.

Asset Quality

The provision for loan losses of $1.4 million recorded for the first quarter of 2016 includes a $2.6 million provision for new loans and net recoupment of valuation allowance of $1.2 million for the acquired loan portfolio due to recoveries and better than expected performance on resolution of acquired loans. The provision for new loans served to increase the related allowance to $26.3 million, or 0.52% of the $5.1 billion in new loans outstanding. The nonperforming new loan ratio as of March 31, 2016 was 0.02%.

Deposits and Borrowings

Deposits totaled $5.9 billion as of March 31, 2016, an increase of 9% from $5.4 billion as of December 31, 2015 and an increase of 40% from $4.2 billion as of March 31, 2015. During the first quarter of 2016, demand deposits increased by $140.2 million, or 11%, from December 31, 2015 and increased by $594.1 million, or 75%, from March 31, 2015. Demand deposits represent 23% of total deposits as of March 31, 2016 as compared to 23% and 19% as of December 31, 2015 and March 31, 2015, respectively. The cost of deposits was 66 basis points for the quarter, representing a 6 basis point increase from the fourth quarter of 2015 and an 11 basis point increase from the first quarter of 2015.

Net Interest Margin and Net Interest Income

The net interest margin for the first quarter of 2016 was 3.65%, a decrease of 4 basis points from the fourth quarter of 2015 and an increase of 7 basis points from the first quarter of 2015. The decrease from the fourth quarter of 2015 was due primarily to an increase of cost of time deposits and borrowings more than offsetting the increase in yield on the new loan portfolio.

Net interest income totaled $64.4 million in the first quarter of 2016, an increase of 4% from $62.0 million in the fourth quarter of 2015 and an increase of 32% from $48.9 million in the first quarter of 2015. Interest income totaled $75.7 million for the first quarter of 2016, an increase of 6% from $71.2 million in the fourth quarter of 2015 and an increase of 37% from $55.4 million in the first quarter of 2015. Interest income from new loans increased by $5.5 million, or 15%, from the fourth quarter of 2015 due to continued growth in the new loan portfolio. Interest income on acquired loans decreased by $1.1 million, or 6%, from the fourth quarter as balance runoff more than offset better than expected cash flow performance. Interest expense was $11.3 million for the first quarter of 2016, an increase of 23% from $9.2 million in the fourth quarter of 2015 and an increase 72% from $6.6 million in the first quarter of 2015. The increase from the fourth quarter of 2015 was a result of an increase of $395.2 million of average interest-bearing liabilities coupled with increased costs associated with the addition of longer duration deposits and borrowings.

Noninterest Income and Noninterest Expense

Noninterest income totaled $5.4 million for the first quarter of 2016 as compared to $7.5 million for the fourth quarter of 2015 and ($54.1) million for the first quarter of 2015. The primary components of noninterest income for the quarter were loan and other fees and bank-owned life insurance income of $2.0 million and $1.3 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 $33.3 million for the first quarter of 2016, in line with expense of $33.2 million in the fourth quarter of 2015 and an increase of 9% from $30.7 million in the first quarter of 2015. For the quarter, the Company recorded non-core expenses of $0.3 million consisting of severance and other salary expense of $0.2 million and cease use expense of $0.1 million relating to branch closures.

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.
