• President and CEO Susan Patricia Griffith’s quarterly letter to shareholders is included as Exhibit 99 to this Quarterly Report on Form 10-Q.

• On April 28, 2023, The Progressive Corporation entered into an Amendment to Discretionary Line Documents (the Amendment) to its unsecured, discretionary line of credit dated April 28, 2017, as amended (the Line of Credit), between The Progressive Corporation and PNC Bank, National Association (PNC), to renew the Line of Credit. The Amendment increased the Line of Credit to a principal amount of $300 million from $250 million and extended the expiration date to April 30, 2024. Subject to the terms and conditions of the Line of Credit documents, advances under the Line of Credit (if any) will bear interest at a variable rate equal to 1-month term Secured Overnight Financing Rate (SOFR) plus 1.10%. Each advance under the Line of Credit must be repaid on the 30th day after the date of the advance or, if earlier, April 30, 2024, the expiration date of the Line of Credit. Prepayments are permitted without penalty. The Line of Credit is uncommitted and, as such, all advances are subject to PNC’s discretion. The Progressive Corporation also entered into an Amended and Restated Discretionary Line of Credit Note (the Note) substantially in the form filed herewith reflecting the increased amount, the new interest rate and other terms and conditions as more fully set forth therein.

The foregoing description of the Amendment and the Note does not purport to be complete and is qualified in its entirety by reference to the Amendment and the Note, copies of which are filed as Exhibits 4.1 and 4.2 hereto and are incorporated herein by reference.
