THIRD quarter 2017 RESULTs

HOUSTON, TEXAS (October 24, 2017) – “We are pleased with the positive progress we are able to report with our third quarter results.  We had a good quarter in many respects.   Credit looks good with one basis point net charge-offs and declines in nonperforming assets.  Loan and deposit growth was solid.  We can see nice linked quarter operating leverage with improved efficiency ratio to 52.2% and returns on average tangible common equity of 13.0% and return on average assets of 1.29%.  I am grateful to our many hard-working bankers who have been focused on improving our results and doing a great job for clients,” said Paul Murphy, Cadence’s Chairman and Chief Executive Officer.

Highlights:

Period End Balance Sheet:

Cadence continued to enjoy solid growth, completing the third quarter of 2017 with total assets of $10.5 billion, an increase of $1,058.3 million, or 11.2%, from September 30, 2016, and an increase of $690.7 million, or 7.0%, from June 30, 2017.  

Organic loan production and pipelines remain robust.  Loans at September 30, 2017 were $8.0 billion, an increase of $821.6 million, or 11.4%, compared with $7.2 billion at September 30, 2016, reflecting growth primarily in our specialized, general C&I and residential portfolios.  Linked quarter loans increased $312.3 million, or 4.0%, from $7.7 billion at June 30, 2017, reflecting growth in general C&I, commercial real estate and residential portfolios.  

Cadence’s energy lending portfolio remained a consistent portion of total loans, with balances totaling $933.0 million, or 11.6%, of total loans at September 30, 2017, as compared to $902.3 million, or 11.7%, of total loans at June 30, 2017.  At September 30, 2017, Midstream continued to make up the largest component of energy loans at 59.8%, followed by Exploration and Production at 31.6% and Energy Services at 8.6%.

Core deposits were $7.7 billion at September 30, 2017, an increase of 14.0%, or $941.8 million, compared to September 30, 2016, and an increase of 6.8%, or $489.6 million, compared to June 30, 2017.  The increases in core deposits were a result of expansion of commercial deposit relationships and treasury management services impacting noninterest bearing and interest bearing deposits, as well as retail time deposit growth.  As of September 30, 2017, brokered deposits totaled $0.8 billion (9.7% of total deposits) as compared to September 30, 2016 at $1.2 billion (14.9% of total deposits) and June 30, 2017 at $0.7 billion (9.4% of total deposits).  Total deposits at September 30, 2017 were $8.5 billion, an increase of $583.8 million, or 7.4%, compared with $7.9 billion at September 30, 2016, reflecting the growth in core deposits offset by $358.0 million, or 30.3%, reduction in brokered deposits.  Linked quarter total deposits increased $570.7 million, or 7.2%, from $7.9 billion at June 30, 2017, due primarily to core deposit growth with an increase of $144.1 million, or 19.4% in brokered deposits during the quarter.  Noninterest bearing deposits as a percent of total deposits increased to 24.4%, representing the fourth consecutive quarterly increase.  Wholesale funds to total assets were 10.2% at September 30, 2017 compared to 12.5% and 9.4% at September 30, 2016 and June 30, 2017, respectively.  

On April 13, 2017, we executed on our initial public offering, issuing 8.6 million shares with net proceeds adding $155.7 million to tangible common equity during the second quarter.  This offering resulted in an increase in average diluted shares to 84.0 million for the third quarter of 2017, as compared to 75.3 million and 82.0 million in the third quarter of 2016 and second quarter of 2017, respectively.

Results of Operations for the Quarter:

Net income for the third quarter of 2017 was $32.6 million, up 393.1% from net income of $6.6 million in the third quarter of 2016, and up 12.5% from net income of $29.0 million in the second quarter of 2017.  The year-over-year net income improvement was driven by earning assets and revenue growth, net interest margin expansion, expense control and improved credit costs including provision expense of $1.7 million for the three months ended September 30, 2017, compared to a provision expense of $29.6 million for the same period in 2016.  The increase in net income as compared to the three months ended June 30, 2017 was due primarily to organic balance sheet and revenue growth combined with a modest increase in expenses and improved credit costs, including a decline of $5.0 million in loan provisions compared to the prior quarter.  Pre-tax, pre-provision earnings⁽¹⁾ were $51.8 million for the third quarter of 2017 as compared to $49.2 million in the second quarter of 2017.  On a per-share basis, net income was $0.39 per diluted common share for the third quarter of 2017, compared to $0.09 a year earlier and $0.35 for the linked quarter.  Earnings per share for the period ending September 30, 2017 reflects increases in net income offset by the $0.04 dilutive effect of the common stock offering in the second quarter of 2017.  During the three months ended September 30, 2017 annualized returns on average assets, common equity and tangible common equity⁽¹⁾ were 1.29%, 9.78% and 13.04%, respectively, as compared to 0.28%, 2.35% and 3.36%, respectively, for the third quarter of 2016, and 1.19%, 9.29% and 12.63% for the second quarter of 2017.

The effective tax rate for the quarter ended September 30, 2017 was 34.9% as compared to 24.2% in the third quarter of 2016 and 31.9% in the second quarter of 2017.  The effective tax rate for the nine months ended September 30, 2017 was 33.3% as compared to 31.4% for the nine months ending September 30, 2016.

Our fully tax-equivalent net interest margin (“NIM”) for the third quarter of 2017 was 3.52% as compared to 3.27% for the third quarter of 2016 and 3.71% for the second quarter of 2017.  The increase in NIM year-over-year resulted from increases in earning asset yields due largely to the impact of short-term rate increases on our floating rate loans during the periods, lagging deposit cost increases, and the impact of decreased interest-sensitive brokered deposits and increased noninterest bearing deposits during the periods.  These year-over-year factors also favorably impacted the margin as compared to the second quarter of 2017; however they were more than offset by lower recovery income (excess accretion) on acquired loans due to timing variability of accelerated payoffs and paydowns driving such revenue (recovery income was $0.3 million in the third quarter of 2017 as compared to $1.4 million in the third quarter of 2016 and $4.5 million in the second quarter of 2017), which resulted in the decline in NIM in the third quarter of 2017 compared to the prior quarter.  

Earning asset yields for the third quarter of 2017 were 4.30%, up from 3.91% in the third quarter of 2016 and down from 4.45% in the second quarter of 2017.  Yield on loans, excluding acquired-impaired loans, were 4.41%, 3.96% and 4.36% for the third quarter of 2017, third quarter of 2016 and second quarter of 2017, respectively, demonstrating the interest-sensitivity inherent in the loan portfolio.  Total loan yields increased to 4.55% for the third quarter of 2017 versus 4.24% for the third quarter of 2016.  Total cost of deposits for the third quarter of 2017 was 64 basis points versus 47 basis points in the prior year’s quarter and 59 basis points in the linked quarter.  Total cost of funds for the third quarter of 2017 was 84 basis points versus 69 basis points in the prior year’s quarter and 81 basis points in the linked quarter.

Net interest income for the third quarter of 2017 was $81.2 million as compared to $70.4 million during the same period in 2016, an increase of $10.7 million, or 15.2%, driven by both strong loan growth during the period and meaningful increases in the yield on loans.  Net interest income decreased $1.2 million, or 1.5%, from $82.4 million in the second quarter of 2017, due to higher level of accretion income in the second quarter of 2017 from acquired-impaired loans.  Interest income on loans, excluding acquired-impaired loans, was $84.3 million for the third quarter of 2017, an increase of $15.9 million, or 23.3%, from the third quarter of 2016, and an increase of $4.4 million or 5.5% from the second quarter of 2017.  Total accretion for acquired credit-impaired loans was $5.8 million in the third quarter of 2017, down $2.8 million from the third quarter of 2016 and down $4.7 million from the second quarter of 2017, as described above, due to the accelerated timing of certain payoffs and paydowns in acquired loans recognized during third quarter of 2016 and second quarter of 2017.  

Noninterest income for the third quarter of 2017 was $27.1 million as compared to $22.8 million during the same period in 2016, an increase of $4.3 million, or 19.0%.  The year-over-year change included an increase in service fees and revenue to $23.0 million at September 30, 2017 versus $20.9 million for September 30, 2016 reflecting broad based business line growth during the year. Compared to the second quarter of 2017, noninterest income increased $4.1 million or 18.0% from $23.0 million for the second quarter of 2017.  The third quarter of 2017 included increases in other revenue due to net valuation increases in certain investment assets accounted for under the equity method and a one-time $1.1 million gain on the sale of a specialty insurance unit.  Assets under management increased slightly to $5.6 billion during the quarter.  

Noninterest expense for the third quarter of 2017 was $56.5 million as compared to $54.9 million during the same period in 2016, an increase of $1.7 million, or 3.0%.  Salaries and employee benefits expense of $35.0 million in the third quarter of 2017 increased $3.9 million, or 12.6%, compared to the third quarter of 2016, including a $1.8 million increase in certain long-term incentive plan costs related to achieving higher levels of performance targets and the increase in our company valuation.  These costs were offset by lower FDIC insurance assessments, intangible asset amortization and other expenses as a result of

3

expense management efforts.  Linked quarter, noninterest expenses increased $0.4 million, or 0.7%, from $56.1 million for the second quarter of 2017.

The efficiency ratio⁽¹⁾ for the third quarter of 2017 was 52.20%, an improvement relative to both the third quarter of 2016 and second quarter of 2017 ratios of 58.87% and 53.27%, respectively, reflecting ongoing focus on efficiency and revenue growth.  The third quarter of 2017 represents the eighth consecutive quarter of improvements in the efficiency ratio for Cadence.

Asset Quality:

Nonperforming assets (“NPAs”) continued to decline during the quarter, totaling $121.8 million, or 1.5%, of total loans, OREO and other NPAs as of September 30, 2017, down from $141.4 million, or 1.8%, as of June 30, 2017, and down from $182.4 million, or 2.5%, as of September 30, 2016.  The declines are due primarily to resolutions, paydowns and general improvement of energy credits.  At September 30, 2017, $98.2 million, or 80.6%, of the NPAs related to the energy portfolio, down from $109.4 million at June 30, 2017.  Additionally, of the $82.0 million in energy nonperforming loans included in total nonperforming assets as of September 30, 2017, over 85% were paying in accordance with contractual terms.

Net-charge offs were $173 thousand during the quarter ended September 30, 2017, as compared to $25.6 million for the three months ended September 30, 2016 and $1.8 million for the three months ended June 30, 2017.  The allowance for credit losses (“ACL”) was $94.8 million, or 1.18% of total loans, as of September 30, 2017, as compared to $91.2 million, or 1.26% of total loans, as of September 30, 2016 and $93.2 million, or 1.21% of total loans, as of June 30, 2017.  At September 30, 2017, the ACL included reserves for the energy portfolio of 2.49% as compared to 3.22% as of September 30, 2016 and 3.15% as of June 30, 2017.  Loan provisions for the third quarter of 2017 were $1.7 million as compared to $29.6 million in the prior year quarter and $6.7 million in the second quarter of 2017.  The declines in loan provisions resulted primarily from the reduction in non-performing loans and related valuation reserves, improved environmental factors in the energy sector and lower net charge-offs.  As of September 30, 2017, the ACL also included approximately $2.0 million in reserves specifically associated with heightened risks surrounding our certain of our mortgage loan customers impacted by the hurricanes in the quarter.

Two “Category 4” hurricanes moved through our geographic footprint during the quarter.  Hurricane Harvey made landfall in Texas in late August and Hurricane Irma hit Florida in early September.  Our technology and operations in the affected areas continued to function throughout the storms, and we were able to re-open all but one of our 25 branches in the impacted footprint for regular business hours within days of the storm and with negligible repairs and costs, and all branches are now open.  Based on our outreach to and analysis of our commercial customers, most with robust business continuity and disaster recovery plans, we have not identified any expected losses in the commercial portfolio to date.  Based on our outreach to and analysis of our mortgage customers in the impacted areas, and in consideration of factors that increase the risks associated with these mortgages, we concluded that increasing reserves by approximately $2.0 million was appropriate as of September 30, 2017.  We will continue to closely monitor all of our impacted customers as recovery efforts continue in the area.

About Non-GAAP Financial Measures

Certain of the financial measures and ratios we present, including “efficiency ratio,” “adjusted noninterest expenses,” “adjusted operating revenue,” “tangible common equity ratio,” “tangible book value per

6

share” and “return on average tangible common equity” and “pre-tax, pre-provision net earnings,” are supplemental measures that are not required by, or are not presented in accordance with, U.S. generally accepted accounting principles (GAAP). We refer to these financial measures and ratios as “non-GAAP financial measures.” We consider the use of select non-GAAP financial measures and ratios to be useful for financial and operational decision making and useful in evaluating period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance by excluding certain expenditures or assets that we believe are not indicative of our primary business operating results or by presenting certain metrics on a fully taxable equivalent basis. We believe that management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, analyzing and comparing past, present and future periods.

These non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP and you should not rely on non-GAAP financial measures alone as measures of our performance. The non-GAAP financial measures we present may differ from non-GAAP financial measures used by our peers or other companies. We compensate for these limitations by providing the equivalent GAAP measures whenever we present the non-GAAP financial measures and by including a reconciliation of the impact of the components adjusted for in the non-GAAP financial measure so that both measures and the individual components may be considered when analyzing our performance.  A reconciliation of non-GAAP financial measures to the comparable GAAP financial measures is included at the end of the financial statement tables (Table 7).
