Houston, TX — October 28, 2015 — Green Bancorp, Inc. (NASDAQ: GNBC), the bank holding company (“Green Bancorp” or the “Company”) that operates Green Bank, N.A. (“Green Bank”), today announced results for its third quarter and nine months ended September 30, 2015.  The Company reported net income for the quarter of $4.1 million, or $0.15 per diluted common share, compared to net income of $4.5 million or $0.20 per diluted common share reported for the same period in 2014.  Excluding one-time acquisition expenses, net income for the third quarter 2015 would have been $4.6 million or $0.17 per diluted common share, compared to $4.8 million or $0.21 per diluted common share reported for the same period in 2014.

Manny Mehos, Chairman and Chief Executive Officer of Green Bancorp said, “Our merger with Patriot Bancshares is a significant step for our company and our employees.  Today we are among the 15 largest banking companies headquartered in Texas.  The merger taken together with continued strong organic growth in our target markets reflects the continued success of our well defined business strategy.  On a pre-tax, pre-provision basis, our performance for the quarter exceed our expectations.”

Geoff Greenwade, President of Green Bancorp and Chief Executive Officer of Green Bank remarked, “Our third quarter results highlight continued solid execution by our bankers as we achieved our annual loan growth objective a full quarter ahead of schedule.  The expense synergies to be recognized in the Patriot deal will largely be achieved this year due to our rapid closing and we continue to project EPS accretion from the merger will be at least 20% in 2016.”

Results of operations for the quarter ended September 30, 2015

Net income for the quarter ended September 30, 2015 was $4.1 million, compared with $4.5 million for the same period in 2014. Net income per diluted common share was $0.15 for the quarter ended September 30, 2015, compared with $0.20 for the same period in 2014. The decrease in net income was principally due to increases in provision for loan

losses and noninterest expense, which includes a $246 thousand increase of one-time acquisition expenses net of tax, offset by increased interest income resulting from growth in loans.  Excluding the one-time acquisition expenses, net income for the quarter would have been $4.6 million, or $0.17 per diluted common share.  Returns on average assets and average common equity, each on an annualized basis, for the three months ended September 30, 2015 were 0.68% and 5.37%, respectively. Green Bancorp’s efficiency ratio, which represents noninterest expense divided by the sum of net interest income and noninterest income, was 59.80% for the three months ended September 30, 2015.  Excluding the impact of one-time acquisition expenses, returns on average assets and average common equity, each on an annualized basis, would have been 0.76% and 6.06%, respectively, and the efficiency ratio would have been 56.44% for the three months ended September 30, 2015.

Net interest income before provision for loan losses for the quarter ended September 30, 2015, was $21.2 million, an increase of $3.7 million, or 20.8%, compared with $17.5 million during the same period in 2014. The increase was primarily due to a 30.8% increase in average loan volume largely driven by the SharePlus acquisition and organic loan growth, somewhat offset by a decrease in the average loan yield. The net interest margin for the quarter ended September 30, 2015 decreased to 3.63%, compared with 3.90% for the same period in 2014. Average noninterest-bearing deposits for the quarter ended September 30, 2015 were $481.9 million, an increase of $107.1 million compared with the same period in 2014, and a decrease of $9.4 million compared to the quarter ended June 30, 2015. Average shareholders’ equity for the quarter ended September 30, 2015 was $301.4 million, an increase of $64.1 million compared with the same period in 2014, and an increase of $5.1 million compared to the quarter ended June 30, 2015.

Net interest income before provision for loan losses during the quarter ended September 30, 2015 increased 1.1% or $239 thousand, compared with $20.9 million for the quarter ended June 30, 2015, primarily due to a 4.6% increase in average loan volume. The net interest margin for the quarter ended September 30, 2015 of 3.63% decreased from 3.84% for the quarter ended June 30, 2015.  The decrease in net interest margin from the prior quarter was primarily due to lower loan yield resulting from lower impact of fee and discount accretion related to loans paid off early and recovered non-accrual interest recorded in the second quarter 2015.

Noninterest income for the quarter ended September 30, 2015 was $2.9 million, an increase of $537 thousand, or 23.0%, compared with $2.3 million for the same period in 2014. This increase was primarily due to the acquired SharePlus operations and servicing income. When comparing the quarter ended September 30, 2015 to the quarter ended June 30, 2015, noninterest income decreased $84 thousand, or 2.8%, from $3.0 million.

Noninterest expense for the quarter ended September 30, 2015 was $14.4 million, an increase of $1.8 million, or 14.4%, compared with $12.6 million for the same period in 2014. The increase was due to a $379 thousand increase of one-time acquisition expenses.  In addition, the increase was due to a $372 thousand increase in professional and regulatory fees; a $255 thousand increase in real estate acquired by foreclosure; a $234 thousand increase in data processing; and a $133 thousand increase in salaries and employee benefits.  Factors contributing to the increase include recurring expenses related to the SharePlus acquisition and related to being a public company.  When comparing the quarter ended September 30, 2015 to the quarter ended June 30, 2015, noninterest expense decreased 13.3%, or $2.2 million, from $16.6 million, primarily due to a $1.2 million decrease of one-time acquisition expenses, a $615 decrease in salaries and wages, and a $230 thousand decrease in occupancy.

Loans held for investment at September 30, 2015 were $2.0 billion, an increase of $477.3 million, or 31.7%, compared with $1.5 billion at September 30, 2014, primarily due to the SharePlus acquisition, continued opportunities for our portfolio bankers to generate new loans and expand existing relationships within our target markets, and increased mortgage warehouse volume. Excluding loans acquired in the SharePlus acquisition based on the acquisition date balance, loans increased $315.5 million, or 21.0% from the September 30, 2014 balance.  Loans held for investment at September 30, 2015 increased $87.5 million, or 4.6%, from June 30, 2015 due to increases in the loan portfolio with mortgage warehouse volume contributing $5.4 million to the quarterly increase.  Average loans held for investment increased 30.8% or $451.4 million to $1.9 billion for the quarter ended September 30, 2015, compared with $1.5 billion for the same period in 2014. Average loans held for investment for the quarter ended September 30, 2015 increased 4.6% or $84.9 million from the quarter ended June 30, 2015.

Deposits at September 30, 2015 were $1.9 billion, an increase of $363.4 million, or 23.0%, compared to September 30, 2014, primarily due to $218.0 million related to the SharePlus acquisition and $94.0 million increase in our commercial deposits. Deposits at September 30, 2015 decreased $83.4 million or 4.1% from June 30, 2015 due primarily to the expected outflow of the prior quarter’s temporary balance increase of approximately $95 million related to a title company relationship. Noninterest-bearing deposits at September 30, 2015 were $499.1 million, an increase of $105.5 million, or 26.8%, compared to September 30, 2014 and a decrease of $105.0 million, or 17.4%, compared to June 30, 2015 due to the title company deposit.  Average deposits increased 21.8% or $340.7 million to $1.9 billion for the quarter ended September 30, 2015, compared with the same period of 2014. Average noninterest bearing deposits for the quarter ended September 30, 2015 were $481.9 million, an increase of $107.1 million compared with the same period in 2014, and a decrease of $9.4 million compared with the quarter ended June 30, 2015.

Results of operations for the nine months ended September 30, 2015

Net income for the nine months ended September 30, 2015 was $12.9 million, compared with $12.7 million for the same period in 2014. Net income per diluted common share was $0.49 for the nine months ended September 30, 2015, compared with $0.58 for the same period in 2014. The increase in net income was principally due to increased interest income resulting from growth in loans. Other factors also contributed to the increase, including an increase in noninterest income and a decrease in interest expense, offset by increases in noninterest expense, provision for loan losses and provision for income taxes.  Returns on average assets and average common equity, each on an annualized basis, for the nine months ended September 30, 2015 were 0.75% and 5.80%, respectively. Green Bancorp’s efficiency ratio was 63.40% for the nine months ended September 30, 2015.

Net interest income before provision for loan losses for the nine months ended September 30, 2015, was $62.6 million an increase of $12.7 million, or 25.5%, compared with $49.9 million during the same period in 2014. The increase was primarily due to a 30.1% increase in average loan volume, partially offset by a 24 basis point decrease in loan yields. The net interest margin for the nine months ended September 30, 2015 decreased to 3.79%, compared with 3.86% for the same period in 2014. Average noninterest-bearing deposits for the nine months ended September 30, 2015 were $468.1 million, an increase of $144.9 million compared with the same period in 2014.

Noninterest income for nine months ended September 30, 2015 was $7.9 million, an increase of $2.0 million, or 33.7%, compared with $5.9 million for the same period in 2014. This increase was primarily due to a $788 thousand increase in customer service fees, a $345 thousand in gain on sale of held for sale loans, a $288 thousand increase in loan fees, and a $240 thousand increase in gain on sale of the guaranteed portion of certain loans.

Noninterest expense for the nine months ended September 30, 2015, was $44.7 million, an increase of $10.2 million, or 29.4%, compared with $34.6 million for the same period in 2014. This increase was primarily due to a $3.7 million increase in salaries and employee benefits resulting from increased staffing principally due to the SharePlus acquisition and increased compensation due to our portfolio banker compensation program and general merit compensation increases; a $2.1 million increase in one-time acquisition expenses; a $1.2 million increase in professional and regulatory fees; a $913 thousand increase in occupancy; a $666 thousand increase in data processing; and  a $418 thousand increase in real estate acquired by foreclosure due to write-downs.  Factors contributing to the increases include recurring expenses related to the SharePlus acquisition and related to being a public company.

Average loans held for investment increased 30.0% or $425.9 million to $1.8 billion for nine months ended September 30, 2015, compared with $1.4 billion for the same period in 2014.  Average deposits increased 25.6% or $386.9 million to $1.9 billion for the nine months ended September 30, 2015, compared with the same period of 2014.

The increase was due primarily to a classified E&P credit relationship moved to nonperforming during the third quarter 2015. Accruing loans classified as troubled debt restructures and included in the nonperforming asset totals were $6.0 million at September 30, 2015, compared with $4.0 million at September 30, 2014.

Non-GAAP Financial Measures

Green Bancorp’s management uses certain non-GAAP (generally accepted accounting principles) financial measures to evaluate its performance. Specifically, Green Bancorp reviews tangible book value per common share, the tangible common equity to tangible assets ratio, allowance for loan losses to total loans excluding acquired loans, allowance for loan losses plus acquired loans net discount to total loans adjusted for acquired loan net discount, selected metrics excluding one-time acquisition expenses and pre-tax, pre-provision adjusted net income.  Green Bancorp has included in this Earnings Release information related to these non-GAAP financial measures for the applicable periods presented.

Capital Management

The Basel III Capital Rules adopted by the federal regulatory authorities in 2013 substantially revised the risk-based capital requirements applicable to Green Bancorp and Green Bank. The Basel III Capital Rules became effective for Green Bancorp on January 1, 2015, subject to a phase-in period for certain provisions. Among other things, the Basel III Capital Rules introduced a new capital measure called “Common Equity Tier 1,” which is a comparison of the sum of certain equity capital components to total risk-weighted assets, and revised the risk-weighting approach of the capital ratios with a more risk-sensitive approach that expanded the risk-weighting categories from the previous Basel I derived categories to a much larger and more risk-sensitive number of categories, depending on the nature of the assets.
