Balances in premiums receivable and the associated allowance account are removed upon cancellation of the policy due to non-payment.We recorded an allowance for uncollectible premiums of $0.0 and $1.0 million at December 31, 2023 and December 31, 2024. 95

Reserves for unpaid losses and loss adjustment expenses incurred, net, also referred to as loss reserves, represent the most significant accounting estimate inherent in the preparation of our financial statements.

We establish two categories of loss reserves as follows:

| • |     | Case reserves—When a claim is reported, we establish an initial estimate of the losses that will ultimately                                                                                                                                          
 be paid on the reported claim. Our initial estimate for each claim is based upon the judgment of our claims professionals who are familiar with property and liability losses associated with the coverage offered by our policies. Then, our claims 
 personnel perform an evaluation of the type of claim involved, the circumstances surrounding each claim and the policy provisions relating to the loss and adjust the reserve as necessary. As claims mature, we increase or decrease the reserve    
 estimates as deemed necessary by our claims department based upon additional information we receive regarding the loss, the results of on-site reviews and any other information we gather while reviewing the                                       
 claims.                                                                                                                                                                                                                                              |

| • |     | IBNR reserves—Our IBNR reserves include true IBNR reserves plus “bulk” reserves. True IBNR
