Pie Insurance received approval in Pennsylvania for a workers’ compensation rate and rule filing that will take effect on April 1, 2026, for both new and renewal business.

The filing adopts the Pennsylvania Compensation Rating Bureau’s April 1, 2026 loss costs and updates Pie’s loss cost multiplier to 1.83 from 1.66. Pie said the PCRB loss cost update accounts for an estimated 4.4% rate impact on its current book, while the higher multiplier brings the combined overall impact to 15.1%.

The filing affects 4,053 policyholders and is expected to increase written premium by about $3.72 million on a book of roughly $24.67 million. Pie’s maximum change is 36.1%, while the minimum change is a 1.6% decrease.

In its filing memorandum, Pie said it began writing workers’ compensation business in Pennsylvania in September 2023 and does not yet have enough state specific historical experience to produce its own indicated rate level change. However, the company said early results have been less favorable than expected, with raw incurred loss and allocated loss adjustment expense ratios above its permissible loss and LAE ratio of 64.5%.
