Northrop Grumman's 2026 Annual Meeting of Shareholders will be held on Wednesday, May 20, 2026.

If you hold Northrop Grumman shares through one of the company savings plans, you should have received an email notification from Broadridge on Monday, April 6 with a subject line of "*Vote Now! NORTHROP GRUMMAN CORPORATION Annual Meeting.*" It would have been sent to your email address on record (either your personal or company address) and includes instructions for viewing the 2026 Proxy Statement and Annual Report, as well as for voting your shares.

You can also vote by visiting www.ProxyVote.com and following the instructions there, or through one of the other ways described in the 2026 Proxy Statement, which can be accessed on the company's investor relations webpage (investor.northropgrumman.com).

Your vote is important, and your input is valued.

Note that you may have received multiple communications (electronically and/or by mail) containing proxy materials and voting instructions for each type of account in which you hold Northrop Grumman shares.
