TEXAS CAPITAL BANCSHARES, INC. ANNOUNCES OPERATING RESULTS FOR 2017

DETAILED FINANCIALS

Texas Capital Bancshares, Inc. reported net income of $197.1 million and net income available to common stockholders of $187.3 million for the year ended December 31, 2017, compared to net income of $155.1 million and net income available to common stockholders of $145.4 million for the year ended December 31, 2016. For the fourth quarter of 2017, net income was $44.7 million and net income available to common stockholders was $42.3 million, compared to net income of $48.4 million and net income available to common stockholders of $45.9 million for the same period in 2016. On a fully diluted basis, earnings per common share were $3.73 for the year ended December 31, 2017 compared to $3.11 for the same period in 2016. Diluted earnings per common share were $0.84 for the quarter ended December 31, 2017 compared to $0.96 for the same period of 2016. The decrease reflects a $17.6 million write-off of our DTA in response to enactment of the Tax Act, which was recorded as additional income tax expense during the fourth quarter. The write-off had an adverse effect of $0.35 on earnings per common share for the 2017 fourth quarter and full year. The federal corporate income tax rates declined from 35% to 21% effective January 1, 2018 as a result of the Tax Act. The amount of the DTA write-off is expected to be recovered in 2018 from cash tax savings attributable to the Tax Act.

Return on common equity ("ROE") was 9.51 percent and return on average assets ("ROA") was 0.87 percent for the year ended December 31, 2017, compared to 9.27 percent and 0.74 percent, respectively, for the year ended December 31, 2016. ROE was 8.18 percent and ROA was 0.71 percent for the fourth quarter of 2017, compared to 11.20 percent and 0.99 percent, respectively, for the third quarter of 2017 and 10.82 percent and 0.85 percent, respectively, for the fourth quarter of 2016. The linked quarter and year-over-year decreases in ROE and ROA for the fourth quarter of 2017 resulted primarily from the DTA write-off, which outpaced the increases in net-interest income and decreases in the provision for credit losses. Excluding the DTA write-off, year-to-date and quarter-to-date December 31, 2017 ROE would have been 10.41% and 11.58%, respectively.

Net interest income was $210.6 million for the fourth quarter of 2017, compared to $204.4 million for the third quarter of 2017 and $171.2 million for the fourth quarter of 2016. The linked quarter and year-over-year increases in net interest income are due primarily to the growth in total LHI. Net interest margin for the fourth quarter of 2017 was 3.47% percent, a decrease of 12 basis points from the third quarter of 2017 and an increase of 36 basis points from the fourth quarter of 2016. Traditional LHI yields were down 3 basis points from the third quarter of 2017, but were up 50 basis points compared to the fourth quarter of 2016. In contrast, total cost of deposits for the fourth quarter of 2017 was up only 6 basis points to 0.53 percent compared to the third quarter of 2017 and up 31 basis points compared to the fourth quarter of 2016. Net interest margin for the fourth quarter of 2017 was adversely affected by increases in mortgage and liquidity assets which are at lower yields than traditional LHI, but produced significant growth in net interest income.

Average LHI, excluding mortgage finance loans, for the year ended December 31, 2017 were $14.0 billion, an increase of $1.7 billion, or 13 percent, from 2016. Average LHI, excluding mortgage finance loans, for the fourth quarter of 2017 were $15.0 billion, an increase of $582.1 million, or 4 percent, from the third quarter of 2017 and an increase of $2.3 billion, or 18 percent, from the fourth quarter of 2016. Average total mortgage finance loans (including MCA) for the fourth quarter of 2017 were $6.2 billion, an increase of $388.9 million, or 7 percent, from the third quarter of 2017 and an increase of $930.2 million, or 17 percent, from the fourth quarter of 2016.

Average total deposits for the year ended December 31, 2017 were $18.5 billion, an increase of $1.2 billion, or 7 percent, from 2016. Average demand deposits for the year ended December 31, 2017 were $8.3 billion, an increase of $196.5 billion, or 2 percent, from 2016. Average total deposits for the fourth quarter of 2017 increased $1.5 billion from the third quarter of 2017 and increased $1.9 billion from the fourth quarter of 2016. Average demand deposits for the fourth quarter of 2017 increased $321.6 million, or 4 percent, to $9.1 billion from $8.8 billion from the third quarter of 2017, and decreased $43.8 million, or 0.48 percent, from the third quarter of 2017.

We recorded a $2.0 million provision for credit losses for the fourth quarter of 2017 compared to $20.0 million for the third quarter of 2017 and $9.0 million for the fourth quarter of 2016. The provision for the fourth quarter of 2017 was driven by the consistent application of our methodology. The linked quarter and year-over-year decreases were primarily related to improvements in the composition of our pass-rated and classified loan portfolios, including energy loans. The combined allowance for credit losses at December 31, 2017 decreased to 1.26 percent of LHI excluding mortgage finance loans compared to 1.30 percent at September 30, 2017 and 1.38 percent at December 31, 2016. In management’s opinion, the allowance is appropriate and is derived from consistent application of the methodology for establishing reserves for the loan portfolio.

We experienced a decrease in non-performing assets in the fourth quarter of 2017 compared to levels reported in the third quarter of 2017 and fourth quarter of 2016, reducing the ratio or total non-performing assets to total LHI plus other real estate owned ("OREO") to 0.55 percent compared to 0.67 percent for the third quarter of 2017 and 1.07 percent for the fourth quarter of 2016. The linked quarter and year-over-year decreases are primarily related to the decrease in energy non-accrual loans from $81.6 million at September 30, 2017 and $121.5 at December 31, 2016 to $65.2 million at December 31, 2017. Net charge-offs for the fourth quarter of 2017 were $964,000 compared to $10.7 million for the third quarter of 2017 and $20.8 million for the fourth quarter of 2016. For the fourth quarter of 2017, net charge-offs related to energy loans were $175,000 compared to net charge-offs of $6.3 million for the third quarter of 2017 and $16.3 million for the fourth quarter of 2016. For the fourth quarter of 2017, net charge-offs were 0.02 percent of average total LHI, compared to 0.22 percent for the third quarter of 2017 and 0.48 percent for the same period in 2016. At December 31, 2017, OREO was $11.7 million compared to $18.1 million at September 30, 2017 and $19.0 at December 31, 2016. The linked quarter and year-over-year decreases were due to a $6.1 million permanent write down of a commercial property during the fourth quarter of 2017.

Non-interest income increased $539,000, or 3 percent, during the fourth quarter of 2017 compared to the same period of 2016, and increased $371,000, or 2 percent, compared to the third quarter of 2017. The year-over-year increase primarily related to a $3.9 million increase in servicing income during the fourth quarter of 2017 compared to the same period of 2016 primarily attributable to an increase in mortgage servicing rights ("MSRs"). Offsetting this increase was a $2.7 million decrease in other non-interest income and a $1.6 million decrease in brokered loan fees, which resulted from a decrease in mortgage finance volumes.

Non-interest expense for the fourth quarter of 2017 increased $26.6 million, or 25 percent, compared to the fourth quarter of 2016, and increased $18.3 million, or 16 percent, compared to the third quarter of 2017. The year-over-year increase is primarily related to a $6.1 million write-down of OREO taken during the fourth quarter of 2017 and a $6.8 million increase in servicing related expenses resulting from a $2.8 million impairment charge primarily due to an anticipated sale of Ginnie Mae MSRs in the first quarter of 2018 and an increase in MSRs, which are being amortized. Non-interest expense for the fourth quarter of 2017 was also affected by increases in salaries and employee benefits, marketing expense and legal and professional expense of $4.1 million, $3.8 million and $2.3 million, respectively, all of which were due to general business growth. The linked quarter increase in non-interest expense was primarily related to the $6.1 million write-down of OREO, as well as a $3.3 million increase in servicing related expenses, which included a $2.8 million impairment charge on MSRs, a $2.4 million increase in legal and professional expense and a $2.3 million increase in salaries and employee benefits.

Stockholders’ equity increased by 10 percent from $2.0 billion at December 31, 2016 to $2.2 billion at December 31, 2017, primarily due to retention of net income. Texas Capital Bank is well capitalized under regulatory guidelines. At December 31, 2017, our ratio of tangible common equity to total tangible assets was 8.1 percent.

(1) The indicated ratios are presented with and excluding the mortgage finance loans because the risk profile of our mortgage finance loans is different than our other loans held for investment. No provision for credit losses is allocated to these loans based on the internal risk grade assigned.

(2) At December 31, 2017, loans past due 90 days and still accruing includes premium finance loans of $5.5 million. These loans are primarily secured by obligations of insurance carriers to refund premiums on canceled insurance policies. The refund of premiums from the insurance carriers can take 180 days or longer from the cancellation date.

(3) At December 31, 2017, loans past due 90 days and still accruing includes $19.7 million in loans held for sale, of which $19.0 million are loans with government guarantees that we purchased and sold into Ginnie Mae pools. Pursuant to Ginnie Mae servicing guidelines we have the unilateral right to repurchase these loans, and therefore must record them as loans held for sale on our balance sheet regardless of whether the repurchase option has been exercised.
