Heritage Reports First Quarter 2021 Results

Clearwater, FL – May 5, 2021: Heritage Insurance Holdings, Inc. (NYSE: HRTG) (“Heritage” or the “Company”), a super-regional property and casualty insurance holding company, today reported first quarter 2021 financial results.

First Quarter 2021 Highlights

Ernie Garateix, the Company’s CEO, said, “We are committed to improving bottom-line results and have implemented meaningful rate increases and underwriting changes that we expect to bear fruit in future periods.”

Quarterly Dividend

Heritage’s Board of Directors declared a quarterly cash dividend of $0.06 per share on the Company’s common stock. The dividend will be paid on July 6, 2021 to shareholders of record as of June 15, 2021.

COVID-19 Update

We continue to monitor the short- and long-term impacts of COVID-19 and through March 31, 2021, we saw virtually no impact to our business. As a residential property insurer, we view our business as relatively insulated from a short-term economic slowdown, as property owners and renters generally view our products as a necessity.

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 or its variants, 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 three months ended March 31, 2021 and 2020 (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 2021 net loss was $5.1 million, down from net income of $7.6 million in the prior year quarter. The decrease primarily stems from elevated weather losses, partly offset by higher net premiums earned.

Gross premiums written were $274.2 million, up 19.7% year-over-year, including 21.9% growth outside Florida and 17.7% growth in Florida. Growth was partly attributable to rate increases, particularly in Florida

Premiums-in-force were $1.1 billion in first quarter 2021, representing a 16.0% annualized growth rate from fourth quarter 2020. The increase stems from the same items impacting gross premiums written.

Gross premiums earned were $270.4 million in first quarter 2021, up 15.2% from $234.7 million in the prior year quarter. The increase reflects higher gross premiums written over the last twelve months.

The ceded premium ratio was 47.4% in first quarter 2021, up 1.1 points from 46.3% in the prior year quarter. The increase is primarily attributable to higher costs associated with excess-of-loss reinsurance coverage, partly offset by higher gross premiums earned.

The net loss ratio was 68.9% in first quarter 2021, up 14.7 points from 54.1% in the prior year quarter. The increase primarily stems from higher current accident year weather and attritional net loss ratios.

The net expense ratio was 38.8% in first quarter 2021, down 2.3 points from 41.1% in the prior year quarter. The decrease primarily stems from a lower G&A expense ratio.

The net combined ratio was 107.7% in first quarter 2021, up 12.5 points from 95.2% in the prior year quarter. The increase stems from a higher net loss ratio, partly offset by a lower net expense ratio, as described above.

Book Value Analysis

Book value per share decreased to $15.32 at March 31, 2021, down 3.9% from December 31, 2020.
