Adjusted net income(1) was $48.5 million, or $1.76 per diluted share, for the second quarter of 2025 as compared to $32.0 million, or $1.25 per diluted share, for the second quarter of 2024.

Second Quarter 2025 Highlights

(1) See discussion of “Non-GAAP and Key Performance Indicators” below.

Mac Armstrong, Chairman and Chief Executive Officer, commented, “Our second quarter results highlight the sustained execution of our Palomar 2X strategic imperative. We achieved strong top and bottom-line growth in the quarter as gross written premium grew 29% across our diverse portfolio and adjusted net income increased 52%. This strong growth underscores the strength of our product set and the efficacy of our balanced book of property and casualty and residential and commercial products. Our financial metrics were equally stout as we generated an adjusted combined ratio of 73%, and a 24% adjusted return on equity.”

Mr. Armstrong continued, “Beyond our financial performance, we remain focused on achieving our 2025 strategic imperatives. Notably, the successful execution of our June 1 reinsurance program at an adjusted rate decrease of approximately 10% year-over-year should help drive consistent earnings the remainder of 2025 and into 2026. We continue to make investments across our organization, that enhance the talent and operational scale of our business and ultimately strengthen the near-term and long-term prospects of Palomar.”

Underwriting Results

Gross written premiums increased 28.8% to $496.3 million compared to $385.2 million in the second quarter of 2024, while net earned premiums increased 47.2% compared to the prior year’s second quarter.

Losses and loss adjustment expenses for the second quarter were $46.2 million, all attritional losses. The loss ratio for the quarter was 25.7%, comprised of an attritional loss ratio of 25.7% and a catastrophe loss ratio(1) of 0.0% compared to a loss ratio of 24.9% during the same period last year comprised of an attritional loss ratio of 22.1% and a catastrophe loss ratio(1) of 2.8%. Additionally, our second quarter results include $6.5 million of favorable prior year development primarily from our short tail Inland Marine and Other Property business.

Underwriting income(1) for the second quarter was $38.3 million resulting in a combined ratio of 78.8% compared to underwriting income of $25.6 million resulting in a combined ratio of 79.1% during the same period last year. The Company’s adjusted underwriting income(1) was $48.4 million resulting in an adjusted combined ratio(1) of 73.1% in the second quarter compared to adjusted underwriting income(1) of $32.9 million and an adjusted combined ratio(1) of 73.1% during the same period last year. The Company’s adjusted combined ratio excluding catastrophe losses(1) was 73.1% compared to 70.3% during the same period last year.

Investment Results

Net investment income increased by 68.0% to $13.4 million compared to $8.0 million in the prior year’s second quarter. The increase was primarily due to higher yields on invested assets and a higher average balance of investments held during the three months ended June 30, 2025 due to cash generated from operations and proceeds from the August 2024 public offering. The weighted average duration of the fixed-maturity investment portfolio, including cash equivalents, was 4.13 years at June 30, 2025. Cash and invested assets totaled

$1.3 billion at June 30, 2025. During the second quarter, the Company recorded $8.3 million net realized and unrealized gains related to its investment portfolio as compared to net realized and unrealized gains of an immaterial amount during the same period last year.

Tax Rate

The effective tax rate for the three months ended June 30, 2025 was 22.3% compared to 22.9% for the three months ended June 30, 2024. For the current quarter, the Company’s income tax rate differed from the statutory rate due primarily to non-deductible executive compensation expense offset by the tax impact of the permanent component of employee stock options.

Stockholders’ Equity and Returns

Stockholders’ equity was $847.2 million at June 30, 2025, compared to $532.6 million at June 30, 2024. For the three months ended June 30, 2025, the Company’s annualized return on equity was 22.7% compared to 19.9% for the same period in the prior year while adjusted return on equity(1) was 23.7% compared to 24.7% for the same period in the prior year.

Share Repurchase Program

The Company’s Board of Directors approved a share repurchase program effective July 31, 2025. The program authorizes the repurchase by the Company of up to $150 million of its outstanding shares of common stock over the period ending on July 31, 2027. Under the share repurchase program, shares may be repurchased from time to time in the open market or negotiated transactions at prevailing market rates, or by other means in accordance with federal securities laws.

There is no guarantee as to the exact number or value of shares that will be repurchased by the Company, and the Company may discontinue repurchases at any time that management determines additional repurchases are not warranted. The timing and amount of share repurchases under the share repurchase program will depend on several factors, including the Company's stock price performance, ongoing capital planning considerations, general market conditions and applicable legal requirements.

Full Year 2025 Outlook

For the full year 2025, the Company expects to achieve adjusted net income of $198 million to $208 million, an increase from the previously announced range of $195 million to $205 million. This range includes an estimate of $8 million to $12 million of catastrophe losses for the remainder of the year.

See “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of total revenue calculated in accordance with GAAP to underwriting revenue.

Adjusted net income is a non-GAAP financial measure defined as net income excluding the impact of certain items that may not be indicative of underlying business trends, operating results, or future outlook, net of tax impact. Palomar calculates the tax impact only on adjustments which would be included in calculating the Company’s income tax expense using the estimated tax rate at which the company received a deduction for these adjustments. See “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of net income calculated in accordance with GAAP to adjusted net income.

Annualized Return on equity is net income expressed on an annualized basis as a percentage of average beginning and ending stockholders’ equity during the period.

Annualized adjusted return on equity is a non-GAAP financial measure defined as adjusted net income expressed on an annualized basis as a percentage of average beginning and ending stockholders’ equity during the period.

Expense ratio, expressed as a percentage, is the ratio of acquisition and other underwriting expenses, net of commission and other income to net earned premiums.

Combined ratio is defined as the sum of the loss ratio and the expense ratio. A combined ratio under 100% generally indicates an underwriting profit. A combined ratio over 100% generally indicates an underwriting loss.

Adjusted combined ratio is a non-GAAP financial measure defined as the sum of the loss ratio and the expense ratio calculated excluding the impact of certain items that may not be indicative of underlying business trends, operating results, or future outlook.

Diluted adjusted earnings per share is a non-GAAP financial measure defined as adjusted net income divided by the weighted-average common shares outstanding for the period, reflecting the dilution which could occur if equity-based awards are converted into common share equivalents as calculated using the treasury stock method. See “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of diluted earnings per share calculated in accordance with GAAP to diluted adjusted earnings per share.

Catastrophe loss ratio is a non-GAAP financial measure defined as the ratio of catastrophe losses to net earned premiums. See “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of loss ratio calculated using unadjusted GAAP numbers to catastrophe loss ratio.
