•	Net interest income increased 4.95% over same quarter in 2017, with net interest margin improving 15 basis points


•	Total loans increased 2.53% year to date driven by strong growth in commercial real estate ("CRE") loans which were up by 5.61% year to date

CORAL GABLES, FL (September 21, 2018) – Mercantil Bank Holding Corporation (the "Company") (NASDAQ: Class A common stock – MBNAA and Class B common stock – MBNAB) today reported second quarter 2018 net income of $10.4 million, or $0.08 per common share, approximately the same as the same quarter in 2017. Net income for the first six months of 2018 was $19.9 million, or $0.16 per share, up 17.49% compared to $16.9 million, or $0.13 per share, for the same period last year. The increase in net income was driven by improved credit quality and higher yields on interest-earning assets, offset by provisions for the costs associated with the Spin-off and lower noninterest income. Adjusting for second quarter Spin-off expenses of $3.2 million and $6.0 million for the first six months of the year not deductible for income tax purposes, net income for the quarter would have been $14.1 million, or $0.11 per common share (up 37.5%), and $25.8 million, or $0.21 per common share for the first six months of the year (up 61.5%).

Millar Wilson, Chief Executive Officer, commented, “We are very pleased to report strong, improving second quarter results, as well as the completion of the Spin-off and our recent listing on NASDAQ. This marks a new chapter for our business as a separate, publicly-traded organization. It creates an opportunity for us to focus on profitable growth strategies as a separate community bank, strengthen our service offerings to better meet customer needs, and expand our footprint in our core markets. We have a dedicated, talented team executing our strategy, and serving our customers and investors. Looking ahead, we will build on this momentum to enhance long-term shareholder value as an independent organization while providing exceptional banking and financial services to our customers.”

Second Quarter 2018 Financial Results

Net interest income was up 4.95% to $54.0 million for the second quarter of 2018, compared to $51.4 million for the same period last year, primarily due to higher average yields on interest-earning assets. Total loans were up 2.53% to $6.2 billion in the second quarter of 2018, compared to $6.1 billion at the end of 2017. Loan growth was driven by a 5.61% increase in CRE loans. Net interest margin for the second quarter improved to 2.77% from 2.62% in the second quarter of 2017.

Total deposits were $6.4 billion at June 30, 2018, up $40.2 million from December 31, 2017, notwithstanding continuing declines in foreign deposits. The increase was driven by increases in time deposits due to customers shifting their deposit preferences as market interest rates increased, and by our promotion of longer-duration time deposits in anticipation of higher rates in the future, generally. This trend partially offset the positive effects of higher rates earned on our earning assets.

Credit quality remains strong. The Company recorded $0.2 million of provisions for loan losses for both the three- and six-month periods ended June 30, 2018, down from the $3.6 million and $7.7 million of provisions recorded during the same periods last year. The decrease is attributed to improvements in quantitative loan loss factors and positive adjustments to qualitative loan loss factors used for CRE and domestic commercial loans. At June 30, 2018, non-performing assets were $35.3 million, compared to $27.3 million as of December 31, 2017, primarily due to two loans.

Noninterest income was $15.0 million for the second quarter of 2018, compared to $17.8 million for the second quarter of 2017, a year-over-year decrease of 15.61%. The decline was due mainly to lower income from wealth management, and lower fee income on derivative and foreign currency exchange transactions. Our assets under management and custody accounts declined $42.4 million, or 2.42%, to $1.71 billion at June 30, 2018 from $1.75 billion at December 31, 2017, primarily due to our decision to close certain foreign customer accounts.

Noninterest expense for the quarter was $52.6 million, compared to $50.7 million in the second quarter of 2017, an increase of 3.89%. The increase was primarily attributable to Spin-off related expenses that were non-deductible for income tax purposes, and higher salary and employee benefit costs as a result of normal annual increases.

Annualized return on assets ("ROA") and return on equity ("ROE") were 0.50% and 5.57%, respectively, during the second quarter of 2018, versus 0.49% and 5.63%, respectively, in the same quarter last year. Excluding Spin-off expenses, annualized ROA and ROE during the most recent quarter were 0.67% and 7.56%, respectively. The adjusted net income improvement of 36.11% is primarily attributable to improved credit quality and higher yields on interest-earning assets.

Our capital is strong and well in excess of minimum regulatory requirements to be “well-capitalized.” At June 30, 2018, the Company’s consolidated total capital, tier 1 risk-based capital, tier 1 leverage and common equity tangible capital (CET1) ratios were 12.61%, 11.67%, 9.87% and 10.13%, respectively.

(16) This presentation contains adjusted financial information, including adjusted noninterest expenses, adjusted net income before income taxes, and the other adjusted items shown, determined by methods other than GAAP.

The adjusted numbers take out the costs incurred by the Company in 2018 related to the Spin-off which commenced in the last quarter of 2017 and continued past June 30, 2018, and which are not deductible for Federal and state income tax purposes. The Company believes these adjusted numbers are useful to understand the Company’s performance absent this event. The following table reconciles these non-GAAP financial measurements as of and for periods presented:

Adjusted efficiency ratio ⁽¹⁸⁾	71.68%			75.43%

(17) Non-GAAP financial measures are not included as of and for the three and six month periods ended June 30, 2017 because no Spin-off costs were incurred for those periods.

(18) Adjusted efficiency ratio is the efficiency ratio less the effect of total Spin-off costs.

(19) The Spin-off caused an unexpected early distribution for U.S. federal income tax purposes from our deferred compensation plan. This distribution is taxable to plan participants as ordinary income during 2018. We are partially compensating plan participants, in the aggregate amount of $1.2 million, for the higher tax expense they will incur as a result of the distribution increasing the plan participants' estimated effective federal income tax rates by recording a contribution to the plan on behalf of its participants. The after tax net effect of this $1.2 million contribution for the period ended June 30, 2018, is approximately $952,000. As a result of the early taxable distribution to plan participants, we will expense and deduct for federal income tax purposes, previously deferred compensation of approximately $8.1 million, resulting in an estimated tax credit of $1.7 million, which exceeds the amount of the tax gross-up paid to plan participants.

(20) Calculated based upon the estimated annual effective tax rate of 22.10%, which excludes the tax effect of discrete items, and the amount that resulted from the difference between permanent Spin-off costs of $5.5 million and $5.8 million for the three and six month periods ended June 30, 2018 that are non-deductible for Federal and state income tax purposes and total Spin-off costs recognized in the consolidated financial statements.
