FOR IMMEDIATE RELEASE

HCI Group Reports Second Quarter and Six-Month 2015 Results

Tampa, Fla. – August 4, 2015 – HCI Group, Inc. (NYSE:HCI) reported results today for the three and six months ended June 30, 2015.

Second Quarter 2015 - Financial Results

Income available to common stockholders in the second quarter of 2015 totaled $22.0 million, or $1.93 diluted earnings per common share, compared with $16.4 million, or $1.39 diluted earnings per common share in the second quarter of 2014.

Gross premiums earned in the second quarter of 2015 increased 18.1% to $107.8 million from $91.2 million in the same period in 2014. The increase was primarily due to the assumption of approximately 6,000 homeowners multi-peril policies and approximately 30,000 wind-only policies from state sponsored Citizens Property Insurance Corporation in December 2014 and 4,000 primarily homeowners multi-peril policies from Citizens in February 2015.

Premiums ceded in the second quarter of 2015 were $31.4 million, or 29.1% of gross premiums earned, compared with $28.6 million, or 31.3% of gross premiums earned, during the same period in 2014.

Net premiums earned (defined as gross premiums earned less premiums ceded to reinsurance companies) in the second quarter of 2015 increased 21.9% to $76.4 million from $62.6 million in the same period in 2014.

Investment related income in the second quarter of 2015, which totaled $1.7 million, was offset by a $293,000 noncash charge due to declines deemed other than temporary in the fair value of securities owned by the company. This compares with $2.6 million in investment related income in the second quarter of 2014, which included $1.2 million of net realized gains from investment sales. The total investment portfolio has grown from $179.2 million at June 30, 2014 to $275.7 million at June 30, 2015.

Losses and loss adjustment expenses during the second quarter of 2015 were $20.6 million compared with $18.4 million in the same period in 2014.

Policy acquisition and other underwriting expenses in the second quarter of 2015 were $10.4 million compared with $9.6 million in the comparable period in 2014. The increase was primarily attributable to commissions and premium taxes related to the policies assumed in December 2014 from Citizens that have renewed and are included in 2015 premiums.

Salaries and wages during the second quarter of 2015 were $5.2 million compared with $4.1 million in the same period in 2014. The increase is primarily attributable to an increase in headcount at the Tampa headquarters.

Interest expense from the company’s senior notes issued in 2013 totaled $2.7 million in the second quarter of 2015 compared with $2.6 million in the second quarter of 2014.

Other operating expenses, which include a variety of general and administrative expenses, totaled $4.6 million in the second quarter of 2015 compared with $5.3 million in the second quarter of 2014. The decrease was primarily attributable to an $863,000 decrease in stock-based compensation offset by an increase in other administrative expenses.

Second Quarter 2015 - Financial Ratios

The loss ratio applicable to the three months ended June 30, 2015 (defined as losses and loss adjustment expenses related to net premiums earned) was 26.9% compared with 29.3% in the three months ended June 30, 2014.

Management Commentary

“During the second quarter, we saw our homeowners’ insurance business produce significant profits and a very low combined ratio resulting from our strict underwriting guidelines,” said Paresh Patel, the company’s chairman and chief executive officer. “Looking forward, we are well positioned to capitalize on the ever-evolving insurance marketplace while we patiently seek strategic growth opportunities.”
