Granite Ridge Resources, Inc.

We are providing our notice of the Special Meeting and access to the proxy statement via the “notice and access” method. Stockholders who share the same last name and address may receive one copy of the Notice of Internet Availability, unless we receive contrary instructions from any stockholder at that address. This practice, known as

“householding,” is designed to reduce the volume of duplicate information and reduce printing and postage costs. Each street name stockholder receiving the Notice of Internet Availability by mail will continue to receive a separate voting instruction form.

We agree to deliver promptly, upon written or oral request, a separate copy of the Notice of Internet Availability to any stockholder at the shared address to which a single copy was delivered. If you prefer to receive separate copies of proxy materials, or if you are currently a stockholder sharing an address with another stockholder and wish to receive only one copy of future Notice of Internet Availability or proxy materials for your household, contact Broadridge Financial Solutions, Inc. at 1-866-540-7095 or in writing at Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717. Stockholders who hold shares in “street name” may contact their bank, broker, or other nominee to request information about householding.
