Heritage Insurance Holdings, Inc. Reports Financial Results for Third Quarter of 2016

Clearwater, FL. – November 8, 2016 - Heritage Insurance Holdings, Inc. (NYSE:HRTG) (“Heritage” or the “Company”), a property and casualty insurance holding company, today reported its financial results for the fiscal quarter ended September 30, 2016.

Third Quarter Highlights

Bruce Lucas, the Company’s Chairman and CEO, said, “Florida experienced its first hurricane in over ten years during the third quarter. Our vertically integrated claims department was instrumental in our response to Hurricane Hermine and we were able to respond efficiently to the needs of our policyholders. Our ability to quickly service policyholders, many within hours of the storm, demonstrates the benefits of our unique approach to managing claims. Losses from the storm were contained, and our current estimate for losses related to Hurricane Hermine is $4 million. Despite the hurricane, I am pleased to report net income of $10.9 million and return on average equity of 11.7 percent for the quarter.”

Quarterly Dividend

The Company announced that its Board of Directors has declared a quarterly cash dividend on the Company’s common stock of $0.06 per share. The fourth quarter dividend of $0.06 per share is payable on January 4, 2017 to stockholders of record as of December 15, 2016. The declaration and payment of any future dividends will be subject to the discretion of the Board of Directors and will depend on a variety of factors including the Company’s financial condition and results of operations.

Results of Operations

The following table summarizes our results of operations for the three and nine months ended September 30, 2016 and 2015 (in thousands, except percentages and per share amounts):

  Third Quarter Financial Results

Net income for the third quarter of 2016 was $10.9 million compared to $16.8 million for the third quarter of 2015.

Gross premiums written were $147.2 million for the third quarter of 2016 compared to $149.0 million for the third quarter of 2015. The roll-out of personal residential business in North Carolina and South Carolina continues with $3.3 million and $200,000 respectively, in gross premium written for the third quarter. This voluntary business expansion in addition to the contribution from Zephyr during the quarter were offset by a lack of Citizens assumption activity as compared to the third quarter of 2015, in which $33.1 million in assumed premiums written was booked.

Gross premiums earned were $164.7 million for the third quarter of 2016 compared to $128.2 million for the third quarter of 2015. Our consolidated premiums in force as of September 30, 2016 and 2015 were approximately $646.0 million and $542.1 million, respectively, and this year-over-year increase had a favorable impact on gross premiums earned.

Ceded premiums as a percentage of gross premiums earned were 38.4% for the third quarter of 2016 compared to 35.8% for the third quarter of 2015. The increase in ceded premium ratio reflects our changing business mix to more wind-only policies and commerical residential business that carry a higher reinsurance expense but lower attritional losses. In the third quarter of 2016, wind-only and commercial residential business represented approximately 33% of our gross premiums earned versus 17% in the third quarter of 2015.

The loss ratio on a gross basis increased to 32.7% for the third quarter of 2016 from 27.9% for the third quarter of 2015, primarily due to severe weather activity, including $4 million in insured losses from Hurricane Hermine, and the impact of litigated and attorney represented claims.

The Company’s expense ratio on a gross basis was 22.3% for the third quarter of 2016 compared to 20.1% for the third quarter of 2015, primarily due to the favorable impact the larger Citizens takeout activity had on the third quarter 2015 acquisition costs.

Overall, Heritage’s combined ratio on a gross basis was 93.4% for the third quarter of 2016 compared to 83.8% for the third quarter of 2015.

First Nine Months of 2016 Financial Results

Net income for the first nine months of 2016 was $36.7 million as compared to $72.3 million for the first nine months of 2015. The decrease in net income was primarily due to the favorable ceded premium ratio recorded in 2015 resulting from larger Citizens’ take-out activity and an increase in the Company’s incurred loss ratio in 2016 due to severe weather activity in the first and third quarters, and adverse development related primarily to litigated and attorney represented claims.

Book Value Analysis

Book value per share increased by 11% from $11.71 at December 31, 2015 to $13.00 at September 30, 2016. The Company repurchased approximately 1.4 million shares of common stock in the first nine months of 2016 pursuant to the Company’s repurchase program.

Subsequent Event: Hurricane Matthew

During the fourth quarter of 2016, Hurricane Matthew impacted Florida and North Carolina where Heritage writes property insurance. Heritage teams have been working diligently to address claims of insureds that were impacted by the storm. Heritage has received approximately 2,500 claims to date related to Hurricane Matthew. At this time, the Company expects pre-tax catastrophe losses could reach approximately $30 million, less than its full retention of $40 million.
