CU BANCORP REPORTS RECORD SECOND QUARTER EARNINGS OF $6.6 MILLION DRIVEN BY RECORD LOAN GROWTH AND REVENUES

Earnings per share increase 24% over year-ago quarter

Los Angeles, CA, July 26, 2016 - CU Bancorp (NASDAQ: CUNB), the parent company of wholly owned California United Bank, today reported financial results for the second quarter of 2016.

Second Quarter 2016 Highlights

Second Quarter 2016 Summary Results

“The second quarter of 2016 was another very strong quarter for CUB, with the Company setting new records for earnings, revenues and loan growth,” said David Rainer, Chairman and Chief Executive Officer of CU Bancorp and California United Bank. “Net income available to common shareholders grew 28% over the year-ago quarter and 6% over the prior quarter, driven by solid growth in both net interest income and non-interest income, with total revenues growing more than 3% on a linked-quarter basis or 14% annualized.

“The evidence of our strong execution can also be seen in the improvement in the Company’s performance ratios. Return on average tangible common equity and return on

average assets of 10.93% and 0.92%, respectively, increased from both year-ago and linked-quarter periods, with tangible book value per share increasing by 12% from the year-ago period.”

“The strong pipeline that we indicated in our first quarter earnings release led to record net organic loan growth of $121 million and total loan growth at an annualized rate of 18%,” said Brian Horton, President of CU Bancorp and California United Bank. “We expect our pipeline will continue to support solid loan growth, similar to the previous six quarters, which have averaged an annualized 12%. We’re pleased to report that included in our second quarter loan growth was a $26 million increase in commercial and industrial loans outstanding, with utilization of commercial and industrial lines of credit returning to 45%.”

“As we noted last quarter, we continue to expect our ongoing growth to require additional staff, with related increases in non-interest expense, in order to support the high level of customer service CUB provides, as well as address expanding regulatory and compliance requirements,” said Rainer. “We are pleased to report that in early July we welcomed Robert Sjogren to fill our newly created position of Executive Vice President and Chief Risk Officer. We are particularly pleased to have found someone with this exemplary background, including experience as an FDIC examiner, a lawyer and a chief operating officer. With this strategic hire, we join the growing number of banks which have recognized that the myriad of new risks, both business and regulatory, require the elevation of the risk management role.”

Net Income and Profitability Ratios

Net income available to common shareholders for the second quarter of 2016 was $6.3 million or $0.36 per fully diluted share, compared with net income available to common shareholders of $5.0 million or $0.29 per fully diluted share for the second quarter of 2015. The growth in net income available to common shareholders from the year-ago quarter is attributable to a $2.5 million increase in loan interest income, which is the result of the Company’s strong loan growth since the prior period. In the second quarter of 2016 the Company recorded no merger-related expenses, compared to $246 thousand in the year-ago quarter.

Net income available to common shareholders for the second quarter of 2016 was $6.3 million or $0.36 per fully diluted share, compared with net income available to common shareholders of $6.0 million or $0.35 per fully diluted share in the first quarter of 2016. The growth in net income available to common shareholders from the prior quarter is primarily attributable to a $587 thousand increase in loan interest income, which is commensurate with the second quarter’s annualized increase in average loans of 13%.

Net income available to common shareholders for the year-to-date period ending June 30, 2016, increased $3.4 million or 39% over the same year-to-date period of 2015. The increase was driven by an increase in net interest income of $6.3 million or 16% for the year-to-date period ending June 30, 2016, compared to the same period of the prior year.

Diluted earnings per share for the year-to-date period ending June 30, 2016, increased $0.18 or 34% compared to the same period of the prior year. Non-interest expense for the year-to-date period ending June 30, 2016, increased $451 thousand or 1.5% compared to the same period of the prior year. Over the prior six quarters non-interest expense has essentially been flat, despite double digit growth in loans and deposits.

The following table shows certain of the Company’s performance ratios for the second quarter of 2016, the first quarter of 2016 and the second quarter of 2015:

Net Interest Income and Net Interest Margin

Net interest income totaled $24.2 million for the second quarter of 2016, an increase of $3.0 million or 14% from the second quarter of 2015. The increase was primarily driven by strong loan growth over the last year.

The Company’s net interest income was positively impacted in both the second quarter of 2016 and the second quarter of 2015 by the recognition of fair value discounts earned on early payoffs of acquired loans. In the second quarter of 2016 the Company recorded $546 thousand in discounts earned on early loan payoffs of acquired loans and other associated payoff benefits of $359 thousand, which had a positive impact on the net interest margin of 14 basis points. In the second quarter of 2015 the Company recorded $474 thousand in discounts earned on early loan payoffs of acquired loans, which had a positive impact on the net interest margin of 9 basis points.

The net interest margin in the second quarter of 2016 was 3.81%, compared to 3.87% in the second quarter of 2015. The decrease was primarily driven by average loans being a lower percentage of earnings assets in the second quarter of 2016 than in the year ago period.

Net interest income for the second quarter of 2016 increased $771 thousand or 3% from the first quarter of 2016. The increase was primarily driven by strong loan growth.

The Company’s net interest income was positively impacted in both the second quarter of 2016 and the first quarter of 2016 by the recognition of fair value discounts earned on early payoffs of acquired loans. In the second quarter of 2016 the Company recorded $546 thousand in discounts earned on early loan payoffs and other associated payoff benefits of $359 thousand, which had a positive impact on the net interest margin of 14 basis points. In the first quarter of 2016 the Company recorded $651 thousand in discounts earned on early loan payoffs of acquired loans and other associated payoff benefits, with a positive impact on the net interest margin of 10 basis points.

The net interest margin in the second quarter of 2016 was 3.81%, compared to 3.77% in the first quarter of 2016. The increase was primarily driven by average loans being a higher percentage of earning assets in the second quarter of 2016 than the previous quarter, as well as higher discounts on acquired loans and other associated payoff benefits earned during the second quarter of 2016.

The core loan yield for the second quarter of 2016 was 4.69%, compared to 4.77% in the previous quarter. The compression of loan yields continues; however, loan growth is offsetting the effect of decreasing rates, which has enabled the Company to continue growing net interest income.

As of June 30, 2016, the Company had $12.1 million of discounts remaining on acquired accruing loans.

The Company’s cost of funds was 0.12% in the second quarter of 2016, compared to 0.13% in both the second quarter of 2015 and the first quarter of 2016.

Non-interest Income

Non-interest income was $3.0 million in the second quarter of 2016, a decrease of $120 thousand or 4% from $3.1 million in the same quarter of the prior year. Other non-interest income in the year-ago quarter included a special dividend of $296 thousand on capital stock from the Federal Home Loan Bank of San Francisco for which there was no equivalent in the second quarter of 2016. Other non-interest income in the second quarter of 2016 included $29 thousand in transaction referral fee income, compared to $380 thousand in the year-ago quarter. The Company’s gain on sale of SBA loans and deposit account income increased $270 thousand and $69 thousand, respectively, in the second quarter of 2016, compared to the year-ago quarter, which reflects growth in areas that are central to the Company’s fundamental strategy.

Non-interest income in the second quarter of 2016 increased $155 thousand or 6% over the first quarter of 2016. The increase was largely due to an increase of $191 thousand in other non-interest income, which included a $68 thousand increase in the dividend on capital stock from the Federal Home Loan Bank of San Francisco, as well as smaller increases in a number of other non-interest income categories, compared with the prior quarter.

Non-interest Expense

Non-interest expense for the second quarter of 2016 was $15.1 million, an increase of $177 thousand, or 1% compared to non-interest expense of $14.9 million for the same period of the prior year. In the second quarter of 2016 salaries and employee benefits increased by $557 thousand over the second quarter of 2015, as full-time equivalent employees grew to

280 at June 30, 2016, an increase of 17 from the end of the year-ago period. The increase in salaries and employee benefits in the second quarter of 2016 was offset by a $276 thousand decrease in other operating expenses, the largest of which was a $101 thousand reduction in the amortization of the core deposit intangible, as well as modest declines in other expenses that fluctuate from quarter to quarter. Additionally, there were no merger-related charges in the second quarter of 2016, which were $246 thousand in the year-ago quarter.

Non-interest expense for the second quarter of 2016 was $15.1 million, a decrease of $98 thousand or 1% over the first quarter of 2016. The Company’s non-interest expense for salaries and benefits decreased by $289 thousand in the second quarter of 2016 compared to the first quarter of 2016, which was largely related to the decline in seasonal compensation expenses incurred annually in the first quarter. Near the end of the second quarter of 2016 the Company increased its full-time equivalent employee count by seven to a total of 280. The decrease in salaries and benefits in the second quarter of 2016 was partially offset by an increase of $176 thousand in legal fees, compared to the first quarter of 2016.

Income Tax

In the second quarter of 2016, the effective tax rate was 40%, the same as the previous quarter.

Balance Sheet

GAAP RECONCILIATIONS

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 analyses of results reported under GAAP. These non-GAAP measures may not be comparable to similarly titled measures reported by other companies.

TCE Calculations and Reconciliation to Total Shareholders’ Equity

(Unaudited)

The Company utilizes the term Tangible Common Equity (TCE), a non-GAAP financial measure. CU Bancorp’s management believes TCE is useful because it is a measure utilized by both regulators and market analysts in evaluating a consolidated bank holding company’s financial condition and capital strength. TCE represents common shareholders’ equity less goodwill and certain intangible assets. A reconciliation of CU Bancorp’s total shareholders’ equity to TCE is provided in the table below for the periods indicated:
