Dear Stockholder:

You are cordially invited to attend the 2024 Annual Meeting of Stockholders of Moody’s Corporation to be held on Tuesday, April 16, 2024, at 9:30 a.m. EDT. Due to the greater access that it provides to our stockholders, the Board of Directors has directed that the 2024 Annual Meeting be held as a “virtual meeting” via the internet. We have designed the format of the Annual Meeting to provide stockholders the same ability to participate that they would have atan in-person meeting.

The Notice of Annual Meeting and Proxy Statement accompanying this letter describe the business to be acted upon at the meeting. The Annual Report for the year ended December 31, 2023 is also enclosed.

On March 6, 2024, we mailed to many of our stockholders a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access our 2024 Proxy Statement and 2023 Annual Report and vote online. The Notice included instructions on how to request a paper ore-mail copy of the proxy materials, including the Notice of Annual Meeting, Proxy Statement, Annual Report, and proxy card or voting instruction card. Stockholders who requested paper copies of the proxy materials or previously elected to receive the proxy materials electronically did not receive a Notice and will receive the proxy materials in the format requested.

Your vote is important. Whether or not you plan to attend the Annual Meeting, we encourage you to review the proxy materials and hope you will vote as soon as possible. You may vote by proxy over the internet or by telephone by using the instructions provided in the Notice. Alternatively, if you requested and received paper copies of the proxy materials by mail, you can also vote by mail by following the instructions on the proxy card or voting instruction card. Voting over the internet, by telephone, or by written proxy or voting instruction card will ensure your representation at the Annual Meeting regardless of whether you attend. Instructions regarding the three methods of voting are contained in the Notice or proxy card or voting instruction card.

IMPORTANT VOTING INFORMATION

Your Participation in Voting the Shares You Own Is Important

If you are the beneficial owner of your shares (meaning that your shares are held in the name of a bank, broker or other nominee), you may receive a Notice of Internet Availability of Proxy Materials from the firm that holds the shares containing instructions that you must follow in order for your shares to be voted. Certain institutions offer telephone and internet voting. If you received the proxy materials in paper form, the materials include a voting instruction card so you can instruct the holder of record on how to vote your shares.

Brokers are not permitted to vote on certain items and may elect not to vote on any of the items, unless you provide voting instructions. To ensure that your shares are voted on all items, you will need to communicate your voting decisions to your bank, broker or other holder of record before the date of the Annual Meeting.

Voting your shares is important to ensure that you have a say in the governance of the Company and to fulfill the objectives of the majority-voting standard that Moody’s Corporation applies in the election of directors. Please review the proxy materials and follow the relevant instructions to vote your shares. We hope you will exercise your rights and fully participate as a stockholder in the future of Moody’s Corporation.
