Heritage Reports First Quarter 2020 Results

Clearwater, FL – May 4, 2020: Heritage Insurance Holdings, Inc. (NYSE: HRTG) (“Heritage” or the “Company”), a property and casualty insurance holding company, today reported first quarter 2020 financial results.

First Quarter 2020 Highlights

Bruce Lucas, the Company’s Chairman and CEO, said, “I want to thank healthcare workers and other essential personnel, including our employees, for supporting our communities during these unprecedented times. As a super-regional property insurer that’s prevailed through multiple hurricanes, we’re well equipped to operate in the current environment and continue to provide our policyholders and agency partners with the high levels of service they’re accustomed to. Homeowners insurance, our core focus, is a must-have product for most consumers, positioning us well in uncertain economic times. Given our confidence in the resilience of our business model, in the first quarter we repurchased 766,900 shares, representing over 3% of year-end 2019 float.”

COVID-19 Update

We are currently monitoring the short- and long-term impacts of COVID-19. During first quarter 2020, we saw virtually no impact to our business. As a residential property insurer, we view our business as relatively insulated from an economic slowdown, as property owners and renters generally view our products as a necessity. The majority of our gross and net premiums written are from renewals of expiring policies. New business, which accounts for a smaller proportion of our sales volume, could be impacted if consumers are not buying as many new homes in our geographies, but this could be partially or fully offset by increased retention in our renewal portfolio.

While we acknowledge uncertainties associated with future economic conditions, we do not expect a material impact to our business going forward. We will continue to monitor economic conditions and, in the case of a prolonged economic slowdown as a result of COVID-19, will take necessary actions to mitigate any negative impacts to our business, operations or financial results.

Results of Operations

The following table summarizes our results of operations for the months ended March 31, 2020 and 2019 (amounts in thousands, except percentages and per share amounts):

* Return on equity represents annualized net income for the period divided by average stockholders’ equity during the period.

Note: Percentages and sums in the table may not recalculate precisely due to rounding.

Ratios

Ceded premium ratio represents ceded premiums as a percentage of gross premiums earned.

Net loss ratio represents net losses and loss adjustment expenses (“LAE”) as a percentage of net premiums earned.

Net expense ratio represents policy acquisition costs (“PAC”) and general and administrative (“G&A”) expenses as a percentage of net premiums earned. Ceding commission income is reported as a reduction of PAC and G&A expenses.

Net combined ratio represents the sum of net losses and LAE, PAC and G&A expenses as a percentage of net premiums earned. The net combined ratio is a key measure of underwriting performance traditionally used in the property and casualty industry. A combined ratio under 100% generally reflects profitable underwriting results.

Quarterly Financial Results

First quarter 2020 net income was $7.6 million, up from $7.0 million in the prior year quarter. The increase primarily reflects higher net premiums earned and a lower net combined ratio, partly offset by lower investment gains and other income and a higher effective tax rate.

Gross premiums written were $229.1 million in first quarter 2020, up 8.9% from $210.3 million in the prior year quarter, including 12.0% growth outside Florida and 6.4% growth in Florida. All states and lines of business experienced positive growth.

Premiums-in-force were $958.1 million in first quarter 2020, representing a 7.4% annualized growth rate from year-end 2019. The increase stems from the same items impacting gross premiums written.

Gross premiums earned were $234.7 million in first quarter 2020, up 2.7% from $228.6 million in the prior year quarter. The increase primarily reflects higher gross premiums written, as described above.

The ceded premium ratio was 46.3% in first quarter 2020, down 5.7 points from 52.0% in the prior year quarter. The decrease is primarily attributable to a reduction in overall quota share reinsurance coverage and reinsurance synergies, partly offset by additional catastrophe excess-of-loss reinsurance coverage.

The net loss ratio was 54.1% in first quarter 2020, down 2.5 points from 56.6% in the prior year quarter. The decrease primarily stems from lower current accident year attritional and weather net loss ratios and higher favorable prior year reserve development, partly offset by lower income from vertically integrated operations. Catastrophe and weather losses in the current year quarter primarily stemmed from February hail, tornado and wind events in the southeast.

The net expense ratio was 41.1% in first quarter 2020, up 0.4 points from 40.7% in the prior year quarter. The increase primarily stems from a modestly higher G&A expense ratio.

The net combined ratio was 95.2% in first quarter 2020, down 2.1 points from 97.3% in the prior year quarter. The decrease stems from a lower net loss ratio, partly offset by a higher net expense ratio, as described above.

Book Value Analysis

Book value per share increased to $16.11 at March 31, 2020, up 9.0% from March 31, 2019.
