CEO Commentary

Chief Executive Officer Katherine Antonello commented: “We are thrilled with our fourth quarter and full-year 2023 results. We closed the year with impressive revenue growth driven by strong increases in both premium writings and investment income. Our growth in written premium in 2023 resulted from a 20% increase in new business coupled with a 9% increase in renewal business, and solid audit premium recognition. Our investment performance also contributed nicely to our overall results and financial strength. Our 2023 net investment income of $106.5 million represented a 19% increase over 2022, and we recognized $70.9 million of after-tax unrealized gains from our fixed maturities, common stock and other investments.”

Ms. Antonello continued, “We maintained our current accident year loss and loss adjustment expense ratio on voluntary business at 63.3%, an improvement over the 64.0% we recorded throughout 2022. Our fourth quarter full reserve study led to the recognition of $24.6 million of net favorable prior year loss reserve development from our voluntary business. Those

actions, coupled with our continual focus on our underwriting expenses yielded an ex-LPT combined ratio of 88.8% for the fourth quarter, down from 91.7% a year ago, and 96.0% for the full year, down from 98.1% a year ago.

Our active capital management efforts throughout 2023, which consisted of $77.1 million of share repurchases and $29.4 million of regular quarterly dividends, coupled with the greater economies of scale we are achieving, further complemented our success in 2023. Our strong balance sheet and abundant underwriting capital are highly supportive of our plans for continued growth and success.

Beyond our financial results, we completed a full integration of Cerity’s operations into those of Employers during the fourth quarter. As a result of this action: (i) we will continue to offer direct-to-consumer policies through the Cerity brand; (ii) we expect to realize meaningful fixed underwriting expense savings going forward; and (iii) we have eliminated the former Cerity segment and have reverted back to being a single segment reporter. With the Cerity integration complete, we are well-positioned to focus our efforts in 2024 on further appetite expansion, and increased self-service options for policyholders, agents and injured workers.

Finally, I want to thank our highly dedicated employees for their outstanding efforts in 2023.”

Summary of Consolidated Fourth Quarter 2023 Results

(All comparisons versus fourth quarter 2022, unless otherwise noted)

Gross premiums written were $178.2 million, an increase of 3%. The increase was primarily due to higher new and renewal business writings. Net earned premiums were $187.5 million, an increase of 4%.

Losses and loss adjustment expenses were $92.9 million, an increase of 2%. The increase was primarily due to higher earned premium, partially offset by a lower current accident year loss and loss adjustment expense ratio and higher net favorable prior year loss reserve development. The Company recognized $24.9 million of favorable prior year loss reserve development during the quarter versus $23.2 million a year ago. The Company’s loss and loss adjustment expense ratio was 49.5% (50.2% excluding LPT) for the quarter versus 50.4% a year ago (51.5% excluding LPT).

Commission expenses of $26.3 million were highly consistent with those of a year ago. The Company's commission expense ratio was 14.0% for the quarter versus 14.4%.

Underwriting and general and administrative expenses of $46.1 million were consistent with those of a year ago. The Company's underwriting and general and administrative expense ratio was 24.6% for the quarter versus 25.8%.

Net investment income was $26.2 million, a decrease of 3%. The decrease was due to lower invested balances of fixed maturity securities, short-term investments and cash and cash equivalents, as measured by amortized cost, partially offset by higher bond yields.

Net realized and unrealized gains on investments reflected on the income statement were $12.1 million versus $13.7 million.

Interest and financing expenses were $0.6 million, a decrease of 70%.The decrease resulted from the recent repayment of all outstanding Federal Home Loan Bank of San Francisco advances.

Other expenses of $1.6 million consisted of a non-recurring charge in connection with previously capitalized cloud computing costs.

Federal and state income tax expense was $12.6 million (21.6% effective rate) versus $8.7 million (15.6% effective rate). The effective rates in each period reflect income tax benefits and exclusions associated with tax-advantaged investment income, LPT adjustments, and deferred gain amortization.

The Company’s book value per share including the deferred gain of $43.88 increased by 16.3% during 2023, computed after taking into account dividends declared. This measure was favorably impacted by $46.6 million of after-tax unrealized gains arising from fixed maturity securities (which are reflected on the balance sheet) and $24.3 million of net after tax unrealized gains arising from equity securities and other investments (which are reflected on the income statement). The Company's adjusted book value per share of $47.26 increased by 10.5% during 2023, computed after taking into account dividends declared. This measure was favorably impacted by $24.3 million of net after tax unrealized gains arising from equity securities and other investments (which are reflected on the income statement).
