Heritage Reports Third Quarter 2023 Results

Tampa, FL – November 2, 2023: Heritage Insurance Holdings, Inc. (NYSE: HRTG) (“Heritage” or the “Company”), a super-regional property and casualty insurance holding company, today reported third quarter of 2023 financial results.

Third Quarter 2023 Result Highlights

• Third quarter net loss of $7.4 million or ($0.28) per diluted share improved from net loss of $48.2 million or ($1.83) per diluted share in the prior year quarter, primarily driven by an increase in net premiums earned, higher net investment income, and lower net losses incurred.

• Gross premiums earned of $337.0 million, up 9.4% from $308.0 million in the prior year quarter.

• Net loss ratio of 74.4%, an improvement of 23.2 points from 97.6% in the prior year quarter.

• Net expense ratio of 36.4%, an increase of 0.7 points from 35.7% in the prior year quarter.

• Net combined ratio of 110.8%, an improvement of 22.5 points from 133.3% in the prior year quarter.

• G&A expense rate increased slightly, predominantly due to investment in systems to drive future efficiencies and speed to market.

• Continued successful exposure management with Florida personal lines policies-in-force intentionally declining by 16.0%, as compared to the prior year period.

“Our policyholders, agents, and employees were affected by two catastrophic events this quarter. In early August, wildfires on the island of Maui caused devastating losses, followed by Hurricane Idalia in the Florida panhandle at the end of the month,” said Heritage CEO Ernie Garateix. “Our policyholders and employees affected by these events remain in our thoughts and we are steadfast in our commitment to fair and timely claims handling,” Garateix emphasized.

“Despite challenges in the property insurance space, including social and actual inflation, increased frequency and severity of catastrophic events, and rising reinsurance costs, I’m encouraged to report a substantial improvement in our financial position and strides toward sustained profitability. Our management team continues to drive exposure management, strengthen underwriting criteria, and work toward rate adequacy throughout our book of business. These strategic efforts are showing promising results as we have seen positive outcomes despite the catastrophe weather experienced during the quarter. Our average premium across the book of business continues to rise meaningfully, reflecting the ongoing focus on profitability.” Garateix concluded, “We are in the business of catastrophe risk, and our results this quarter were impacted accordingly. Nonetheless, we maintain our focus on appropriate risk management and high-quality service for our customers. Weather events underscore the importance of our role, and we are prepared to support our clients and communities as we all work toward recovery.”

Strategic Profitability Initiatives

The following provides an update to the Company’s strategic initiatives that are expected to enable Heritage to achieve consistent long-term quarterly earnings and drive shareholder value. The Supplemental Information table included in this earnings release demonstrates progress made on these initiatives compared to the third quarter 2022.

• Generate underwriting profit though rate adequacy and more selective underwriting.

• Continued significant rating actions throughout the book of business resulting in an increase in average premium per policy throughout the book of 25.5% compared to the third quarter of 2022 and 5.1% from the second quarter of 2023.

• Premiums-in-force of $1.3 billion were up 8.4% from the prior year quarter, while policy count was down 13.6%, driven by continued underwriting efforts to manage exposure for personal residential business while selectively growing the Company’s commercial residential business. Continued strategic tightening of underwriting criteria led to a temporary decline in new business, particularly in over-concentrated or underpriced markets. This proactive measure is pivotal for long-term portfolio health and risk management, especially in geographies with higher catastrophe risk.

• Allocate capital to products and geographies that maximize long-term returns.

• Strategically increased Florida commercial residential premiums-in-force by 75.3% over the prior year quarter while total insured value (“TIV”) for that product increased 30.9% and policies in force increased by only 9.5%.

• Reduction of policy count for the Florida personal lines product to continue goal of improving the quality of the book of business. Policies in force for Florida personal lines business intentionally declined by 16.0% as compared to the prior year period and 4.2% from the second quarter of 2023.

• This disciplined underwriting approach resulted in a policy count reduction from the prior year quarter of 12.6% in other states with only a 1.1% decrease in premiums-in-force.

• Maintain a balanced and diversified portfolio.

• Even with the substantial increase in commercial residential business, no state represents over 26.5% of the Company’s TIV.

• The top four states grew TIV by an average of 0.6% while the smallest five states grew TIV by 24.5%.

• As a result of diversification efforts, the top five personal lines states represented 71.7% of all TIV at third quarter 2023 compared to 72.2% of all TIV at third quarter 2022.

• Florida’s TIV increased by 1.8%, a result of intentional growth in the Company’s commercial residential product offerings and the adoption of inflation guard, which ensures accurate replacement cost values across all business sectors. This was partly offset by a reduction in Florida personal lines policies compared to the previous year’s quarter. TIV outside of Florida accounted for 73.5% of the entire portfolio, a slight decrease from 74.8% in the third quarter of 2022. This change was driven by ongoing exposure management in personal lines business across the portfolio and selective expansion of Florida’s commercial lines business.

• Provide coverage suitable to the market and return targets.

• Selective use of Excess & Surplus lines (“E&S”) premium-in-force in California, Florida, and South Carolina.

• Continue to evaluate other strategic states for E&S products.

Capital Management

Heritage’s Board of Directors has decided to continue its suspension of the quarterly dividend to shareholders. The Board of Directors will continue to evaluate dividend distribution and stock repurchases on a quarterly basis. No shares of common stock were repurchased during the quarter.

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.

Third Quarter 2023 Results

• Third quarter net loss of $7.4 million or $(0.28) per diluted share, an improvement from a net loss of $48.2 million or ($1.83) per diluted share in the prior year quarter. This improvement is attributable to growth of 10.6% in net premiums earned, an increase of 137.8% in net investment income, and a reduction of 15.7% in net losses and LAE. It was partly offset by elevated policy administration and general and administrative costs, largely due to the increase in gross premiums written over the prior year quarter and operational investments, culminating in a lower combined ratio compared to the same period last year.

• Premiums-in-force of $1.3 billion, represented an 8.4% increase from third quarter 2022 due to continued proactive rate increases across the entire portfolio and underwriting actions, despite an intentional policy count reduction of approximately 74,000 policies. Premiums-in-force were also favorably impacted by strategic growth of the Company’s commercial residential product and use of inflation guard across all products.

• Gross premiums written were $309.5 million, up 1.6% from $304.5 million in the prior year quarter, reflecting a strategic and substantial increase in Florida commercial residential lines business and a higher average premium per policy throughout the book of business, partly offset by targeted exposure management. Gross premiums written for Florida personal lines business was up $5.8 million due to rate increases, despite a 16.0% reduction in policy count from the prior year quarter.

• Gross premiums earned of $337.0 million, up 9.4% from $308.0 million in the prior year quarter, reflecting higher gross premiums written over the last twelve months driven by a higher average premium per policy and organic growth of the commercial residential business.

• Net premiums earned of $176.7 million, up 10.6% from $160.0 million in the prior year quarter, reflecting higher gross premium earned outpacing the increase in ceded premiums for the quarter.

• Ceded premium ratio of 47.6%, down 0.5 points from 48.1% in the prior year quarter driven by 9.4% growth in gross premiums earned outpacing the growth of ceded premiums of 8.1%.

• Net loss ratio decreased to 74.4%, a 23.2 point decline from 97.6% in the same quarter last year reflecting higher net premiums earned and reduced net losses and LAE. The reduction in net losses and LAE improved largely due to diminished weather and attritional losses. Net weather losses for the current accident year were $51.6 million, a decrease from $63.8 million in the previous year’s quarter. Catastrophe losses remained consistent at $40.0 million, with this quarter’s losses attributed to the Maui wildfire and Hurricane Idalia and prior year quarter’s losses from Hurricane Ian. Other weather losses totaled $11.5 million, showing a reduction from the prior year quarter amount of $23.8 million. Additionally, the net loss ratio experienced an impact from net unfavorable loss development of $793,000, a deviation from the net favorable $1.0 million development in the third quarter of 2022.

• The net expense ratio was 36.4% in third quarter 2023, up 0.7 points from the prior year quarter amount of 35.7%, driven by higher general and administrative costs mostly related to software and associated costs with the implementation of a new claims system aimed at driving future efficiencies.

• Net combined ratio of 110.8%, improved 22.5 points from 133.3% in the prior year quarter, driven by a lower net loss ratio as described above.

• Net investment income, inclusive of realized investment losses and unrealized losses on equity securities, was $6.5 million in third quarter 2023, up from $2.9 million in the prior year quarter reflecting actions to align the investments with the yield curve.

• Effective tax rate was 38.3% compared to 2.2% in the prior year quarter, driven by the impact of changes to a valuation allowance which is updated quarterly, as well as permanent differences in relation to projected annual pre-tax income or loss. The valuation allowance relates to tax elections made by Osprey Re, the Company’s captive reinsurer domiciled in Bermuda. For the current year quarter, the valuation allowance decreased, while for the prior year quarter, the valuation allowance was established.

Book Value Analysis

Book value per share of $5.65 at September 30, 2023, was up 10.1% from fourth quarter 2022 and 24.4% from third quarter 2022. The increase from the comparable quarter of 2022 is primarily attributable to year-to-date net income through the third quarter of 2023 as well as a reduction in unrealized losses on the Company’s fixed income securities portfolio from the third quarter of 2022. The unrealized losses are unrelated to credit risk but due to the rising interest rate environment during 2022 and 2023.
