Dear Stockholder:

We are providing additional information and context on our proposal to approve the Kinsale Capital Group, Inc. 2025 Omnibus Incentive Plan (the "Plan") at our 2025 Annual Meeting of Stockholders. If the Plan is approved by our stockholders, no further awards will be issued under the Kinsale Capital Group, Inc. 2016 Omnibus Incentive Plan (the "2016 Plan") on or following the date the Plan is approved by our stockholders and the shares remaining available for grant of future awards under the 2016 Plan will not carry forward to the Plan. In addition, any shares granted under the 2016 Plan on or following March 27, 2025 will reduce the number of shares subject to the Plan by the same number.

Sincerely,

Michael P. Kehoe
Chairman and Chief Executive Officer
