Exhibit 99.1

Kinsale Capital Group Reports First Quarter 2026 Results

Richmond, VA, April 23, 2026 - Kinsale Capital Group, Inc. (NYSE: KNSL) reported net income of $112.6 million, $4.88 per diluted share, for the first quarter of 2026 compared to $89.2 million, $3.83 per diluted share, for the first quarter of 2025. Net income included after-tax catastrophe losses of $1.3 million in the first quarter of 2026 and $17.8 million in the first quarter of 2025. Net operating earnings(1) were $117.8 million, $5.11 per diluted share, for the first quarter of 2026 compared to $86.4 million, $3.71 per diluted share, for the first quarter of 2025.

Three Months Ended March 31,

2026 2025 % Change

Diluted earnings per share $ 4.88 $ 3.83 27.4 %

Diluted operating earnings per share(1)

$ 5.11 $ 3.71 37.7 %

Highlights for the quarter included:

•Gross written premiums decreased by 0.5% to $482.0 million

•Net written premiums increased by 5.6% to $403.3 million

•Net investment income increased by 26.5% to $55.4 million

•Underwriting income(2) was $94.5 million, resulting in a combined ratio(5) of 77.4%

•Annualized operating return on equity(7) was 24.0% for the three months ended March 31, 2026

"Our first quarter results demonstrate exceptional profitability," said Chairman, President and Chief Executive Officer, Michael P. Kehoe. "We have confidence in our strategy of underwriting discipline and maintaining structurally low costs. Particularly in a competitive market, we remain focused on delivering long-term stockholder value throughout the market cycle by generating consistent and attractive underwriting profits while managing our capital prudently."

Results of Operations

Underwriting Results

Gross written premiums were $482.0 million for the first quarter of 2026 compared to $484.3 million for the first quarter of 2025, a decrease of 0.5%. The decrease in gross written premiums was primarily due to a 28.3% decline in the Commercial Property Division, one of the Company's largest divisions, driven by continued rate decreases from heightened competition, including from standard carriers. Excluding the Commercial Property Division, gross written premiums increased 6.0% compared to the prior-year period, reflecting continued strong submission flow across most divisions.

Net written premiums were $403.3 million for the first quarter of 2026 compared to $381.7 million for the first quarter of 2025, an increase of 5.6%. The increase in net written premiums was primarily due to an increase in retention on the Company's reinsurance treaties effective with the June 2025 renewal.

Underwriting income(2) was $94.5 million, resulting in a combined ratio(5) of 77.4% for the first quarter of 2026, compared to $67.5 million and a combined ratio(5) of 82.1% for the same period last year. The increase in underwriting income(2) was largely due to growth in net earned premiums, lower catastrophe losses and higher favorable development of loss reserves from prior accident years.

Loss(3) and expense(4) ratios were 56.3% and 21.1%, respectively, for the first quarter of 2026 compared to 62.1% and 20.0% for the first quarter of 2025. Results for the first quarter of 2026 and 2025 included net

favorable development of loss reserves from prior accident years of $18.7 million, or 4.5 points, and $14.6 million, or 3.9 points, respectively. The loss ratio for the first quarter of 2026 included 0.4 points of net catastrophe losses. The loss ratio for the first quarter of 2025 included 6.0 points of net catastrophe losses, primarily related to the Palisades Fire. The increase in the expense ratio to 21.1% in the first quarter of 2026 from 20.0% in the first quarter of 2025 was primarily due to lower ceding commissions as a result of higher retention on the Company’s reinsurance treaties. The economic effect of lower ceding commissions was more than offset by the retention of incremental underwriting margin and higher investment income.

Summary of Operating Results

The Company’s operating results for the three months ended March 31, 2026 and 2025 are summarized as follows:

Investment Results

Net investment income was $55.4 million in the first quarter of 2026 compared to $43.8 million in the first quarter of 2025, an increase of 26.5%. This increase was driven by growth in the Company's investment portfolio generated largely from the investment of strong operating cash flows. The Company’s investment portfolio had an annualized gross investment return(8) of 4.5% and 4.3% for the first quarter of 2026 and 2025, respectively. Funds are generally invested conservatively in high-quality securities with an average credit quality of "AA-" and the weighted average duration of the fixed-maturity investment portfolio, including cash equivalents, was 4.1 years and 4.0 years at March 31, 2026 and December 31, 2025, respectively. Cash and invested assets totaled $5.3 billion at March 31, 2026 and $5.2 billion at December 31, 2025.

(8) Gross investment return is investment income from fixed-maturity and equity securities (and short-term investments, if any), before any deductions for fees and expenses, expressed as a percentage of average beginning and ending book values of those investments during the period.

Capital Return to Stockholders

During the first quarter of 2026, the Company repurchased 166,042 shares of its common stock in the open market at an average price of $376.41 per share for a total cost of $62.5 million. At March 31, 2026, the Company had $187.5 million of capacity remaining under its share repurchase program.

During the first quarter of 2026, the Company declared and paid a cash dividend of $0.25 per share of common stock for a total distribution of $5.7 million.

Other

The effective tax rates for the three months ended March 31, 2026 and March 31, 2025 were 19.4% and 20.6%, respectively. In the first quarter of 2026 and 2025, the effective tax rates were lower than the federal statutory rate of 21% primarily due to the tax benefits from stock-based compensation, including stock options exercised, and from tax-exempt investment income.

Stockholders' equity was $2.0 billion at both March 31, 2026 and December 31, 2025. Book value per share was $85.31 at March 31, 2026 compared to $84.66 at December 31, 2025. Annualized operating return on equity(7) was 24.0% for the first three months of 2026, an increase from 22.5% for the first three months of 2025. The increase was due primarily to higher profitability compared to the prior-year period offset in part by higher average stockholders' equity.

Non-GAAP Financial Measures

Net Operating Earnings

Net operating earnings is defined as net income excluding the effects of the change in the fair value of equity securities, after taxes, net realized investment gains and losses, after taxes, and change in allowance for credit losses on investments, after taxes. Management believes the exclusion of these items provides a useful comparison of the Company's underlying business performance from period to period. Net operating earnings and percentages or calculations using net operating earnings (e.g., diluted operating earnings per share and annualized operating return on equity) are non-GAAP financial measures. Net operating earnings should not be viewed as a substitute for net income calculated in accordance with GAAP, and other companies may define net operating earnings differently.

For the three months ended March 31, 2026 and 2025, net income and diluted earnings per share reconcile to net operating earnings and diluted operating earnings per share as follows:

(1) Income taxes on adjustments to reconcile net income to net operating earnings use a 21% effective tax rate.

(2) Diluted operating earnings per share may not add due to rounding.

(3) Average equity is computed by adding the total stockholders' equity as of the date indicated to the prior quarter-end or year-end total, as applicable, and dividing by two.

(4) 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.

(5) Annualized operating return on equity is net operating earnings expressed on an annualized basis as a percentage of average beginning and ending stockholders' equity during the period.

Underwriting Income

Underwriting income is defined as net income excluding net investment income, the change in the fair value of equity securities, net realized investment gains and losses, change in allowance for credit losses on investments, interest expense, other expenses, other income and income tax expense. The Company uses underwriting income as an internal performance measure in the management of its operations because the Company believes it gives management and users of the Company's financial information useful insight into the Company's results of operations and underlying business performance. Underwriting income should not be viewed as a substitute for net income calculated in accordance with GAAP, and other companies may define underwriting income differently.

For the three months ended March 31, 2026 and 2025, net income reconciles to underwriting income as follows:
