Cadence Bancorporation reports

SECOND quarter 2017 RESULTs

“We are pleased to report our second quarter results.  The quarter reflected record net income, driven by continued organic growth and an ongoing focus on efficiency and profitability.  We have seen meaningful customer acquisition and development throughout the company, as well as positive movement in our margins and continued stabilization of credit.  Our bankers have focused on core deposit growth, and generated a notable improvement in deposit mix this quarter.  We feel good about the quarter’s results, and our team is optimistic and energized about our progress,” said Paul Murphy, Cadence’s Chairman and Chief Executive Officer.

Period End Balance Sheet:

Cadence continued to enjoy solid growth, completing the second quarter of 2017 with total assets of $9.8 billion, an increase of $589.8 million, or 6.4%, from June 30, 2016, and an increase of $90.6 million, or 0.9%, from March 31, 2017.  

Loans at June 30, 2017 were $7.7 billion, an increase of $554.6 million, or 7.7%, compared with $7.2 billion at June 30, 2016, reflecting growth primarily in our commercial and residential loan portfolios.  Linked quarter loans increased $155.1 million, or 2.1%, from $7.6 billion at March 31, 2017, reflecting growth in specialized, general commercial & industrial and consumer mortgage lending.  Organic loan

production as well as our pipeline remains robust, with payoffs and paydowns impacting net growth in the quarter.  

Cadence’s energy lending portfolio continued to demonstrate improving credit quality, with balances totaling $902.3 million, or 11.7%, of total loans at June 30, 2017, as compared to $903.9 million, or 11.9%, of total loans at March 31, 2017.   At June 30, 2017, Midstream continued to make up the largest component of energy loans at 54.7%, followed by Exploration and Production at 35.7% and Energy Services at 9.6%.

Core deposits were $7.2 billion at June 30, 2017, an increase of 12.8%, or $813.7 million, compared to June 30, 2016, and an increase of 6.1%, or $410.2 million, compared to March 31, 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 June 30, 2017, brokered deposits totaled $0.7 billion (9.4% of total deposits) as compared to June 30, 2016 at $1.3 billion (16.9% of total deposits) and March 31, 2017 at $1.1 billion (13.6% of total deposits).   Total deposits at June 30, 2017 were $7.9 billion, an increase of $257.7 million, or 3.4%, compared with $7.7 billion at June 30, 2016, reflecting the growth in core deposits offset by $556.0 million, or 42.8%, reduction in brokered deposits.  Linked quarter total deposits increased $88.7 million, or 1.1%, from $7.8 billion at March 31, 2017, due primarily to the core deposit growth supporting proactive reductions in brokered deposits during the quarter, with brokered deposits declining $321.5 million, or 30.2%, linked quarter.  Wholesale funds to total assets of 9.4% at June 30, 2017 improved meaningfully during the quarter as compared to 14.1% and 14.7% at June 30, 2016 and March 31, 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 quarter, and increasing average diluted shares to 82.0 million for the second quarter of 2017, as compared to 75.3 million and 75.7 million in the second quarter of 2016 and first quarter of 2017, respectively.

Results of Operations for the Quarter:

Net income for the second quarter of 2017 was $29.0 million, up 95.2% from net income of $14.8 million in the second quarter of 2016, and up 10.9% from net income of $26.1 million in the first quarter of 2017.  The year-over-year net income improvement was driven by continued earning asset and revenue growth, margin improvement, flat expenses and improved credit costs.   The increase in net income on a linked quarter basis was due primarily to organic growth, a favorable impact of the recent short-term rate increases on our net interest margin, and favorable recovery results in acquired-credit-impaired loans.  Pre-tax, pre-provision earnings⁽¹⁾ were $49.2 million for the second quarter of 2017 as compared to $44.5 million in the first quarter of 2017.  On a per-share basis, net income was $0.35 per diluted common share for the second quarter of 2017, compared to $0.20 a year earlier and $0.35 for the linked quarter.  Earnings per share for the period ending June 30, 2017 reflects increases in net income offset by the $0.03 dilutive effect of the common stock offering in the second quarter of 2017.  The second quarter of 2017 annualized returns on average assets, common equity and tangible common equity⁽¹⁾ were 1.19%, 9.29% and 12.63%, respectively, as compared to 0.65%, 5.47% and 7.90%, respectively, for the second quarter of 2016, and 1.10%, 9.71% and 13.96% for the first quarter of 2017.   

Net interest margin for the second quarter of 2017 was 3.71% as compared to 3.32% for the second quarter of 2016 and 3.46% for the first quarter of 2017.   The increase resulted from deposit costs lagging the change in earning asset yields due to short-term rate increases during the periods, the impact of

decreased interest-sensitive brokered deposits and increased free-funding sources during the periods, as well as, increased loan yields in both the originated and acquired loan portfolios. Earning asset yields for the second quarter of 2017 were 4.45%, up from 3.97% in the second quarter of 2016 and 4.13% in the first quarter of 2017.  Total cost of deposits for the second quarter of 2017 was 59 basis points versus 46 basis points in the prior year’s quarter and 49 basis points in the linked quarter.  Total cost of funds for the second quarter of 2017 was 81 basis points versus 69 basis points in the prior year’s quarter and 71 basis points in the linked quarter.

Net interest income for the second quarter of 2017 was $82.4 million as compared to $69.3 million during the same period in 2016, an increase of $13.1 million, or 19.0%.  Linked quarter, net interest income increased $7.6 million, or 10.2%, from $74.8 million in the first quarter of 2017. The increases were driven by both solid loan growth during the periods and meaningful increases in the yield on loans, with loan yields increasing to 4.74% for the second quarter of 2017 versus 4.24% for the second quarter of 2016 and 4.34% for the first quarter of 2017.   Yield on loans, excluding acquired-impaired loans, were 4.36%, 3.93% and 4.14% for the second quarter of 2017, second quarter of 2016 and first quarter of 2017, respectively, demonstrating the interest-sensitivity inherent in the loan portfolio.  Interest income on loans, excluding acquired-impaired loans, was $79.9 million for the second quarter of 2017, an increase of $13.4 million, or 20.3%, from the second quarter of 2016, and an increase of $6.0 million or 8.2% from the first quarter of 2017.  Total accretion for acquired credit-impaired loans was $10.6 million in the second quarter of 2017, up $1.3 million from the second quarter of 2016 and up $3.6 million from the first quarter of 2017.   The increased accretion in the second quarter of 2017 was due to accelerated timing of certain payoffs and paydowns in acquired loans.  

Noninterest income for the second quarter of 2017 was $23.0 million as compared to $23.1 million during the same period in 2016, a decrease of $0.1 million, or 0.5%.  The year-over-year change included an increase in service fees and revenue to $22.1 million at June 30, 2017 versus $20.0 million for June 30, 2016 reflecting broad based business line growth during the year, partially offset by lower securities gains and other revenues in the second quarter of 2017. Linked quarter, noninterest income decreased $1.1 million or 4.6% from $24.1 million for the first quarter of 2017.  The quarter’s change included growth in mortgage banking fees, offset primarily by the impact of first quarter 2017 seasonally higher trust and insurance revenues in the second quarter of 2017. Assets under management grew $187.5 million, or 3.5%, during the quarter to $5.6 billion.  

Noninterest expense for the second quarter of 2017 was $56.1 million as compared to $55.9 million during the same period in 2016, an increase of $0.2 million, or 0.5%.  Salaries and employee benefits expense of $34.7 million in the second quarter of 2017 increased $1.6 million, or 5.0%, compared to the second quarter of 2016, including a $1.0 million increase in certain long-term incentive plan costs related to the increase in our common stock value associated with our becoming a public company. These costs were offset by lower FDIC insurance assessments, lower intangible asset scheduled amortization and other expenses as a result of targeted expense management efforts.  Linked quarter, noninterest expenses increased $1.8 million, or 3.3%, from $54.3 million for the first quarter of 2017, including the $1.0 million in incremental incentive compensation expense associated with the second quarter valuation increase of Cadence Bancorporation associated with its IPO.

The efficiency ratio⁽¹⁾ for the second quarter of 2017 was 53.27%, an improvement relative to both the second quarter of 2016 and first quarter of 2017 results of 60.49% and 54.95%, respectively, reflecting ongoing focus on efficiency and revenue growth.

Asset Quality:

Nonperforming assets (NPAs) declined during the quarter, totaling $141.4 million, or 1.8%, of total loans, OREO and other NPAs at June 30, 2017, down from $171.0 million, or 2.3%, at March 31, 2017, and down from $195.5 million, or 2.7%, at June 30, 2016.  The decline as compared to the prior year is due primarily to resolutions, paydowns, and general improvement of energy credits.  At June 30, 2017, $109.4

million, or 77.4%, of the nonperforming assets (“NPAs”) related to the energy portfolio, down from $135.0 million at March 31, 2017.  Additionally, of the $93.0 million in energy nonperforming loans included in total nonperforming assets at June 30, 2017, over 90% were paying in accordance with contractual terms.

The allowance for credit losses (“ACL”) was $93.2 million, or 1.21% of total loans, at June 30, 2017, as compared to $87.1 million, or 1.22% of total loans, at June 30, 2016 and $88.3 million, or 1.17% of total loans, at March 31, 2017.  At June 30, 2017, the allowance included reserves for the energy portfolio of 3.15% as compared to 2.80% at June 30, 2016 and 3.44% at March 31, 2017.

“With the momentum we have achieved year-to-date, we look forward to and are positive about the outlook for Cadence,” stated Mr. Murphy.

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 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).
