Explanation of Responses:

Id	Content
F1	Held in the Northrop Grumman Savings Plan (the "Plan"), a qualified defined contribution plan, as of 2/14/24. Share totals with respect to the Plan are based upon unit accounting and therefore may reflect a change in units attributable to an individual though no acquisition or disposition occurred.
F2	Each Restricted Stock Right ("RSR") represents a contingent right to receive an equivalent number of shares in Issuer common stock, or, at the election of the Issuer's Compensation Committee, cash or a combination of cash and Issuer common stock. The RSRs were granted under the Long-Term Incentive Stock Plan ("LTISP") on 2/14/24 and will vest on 2/14/27.
F3	Each Restricted Performance Stock Right ("RPSR") represents a contingent right to receive an equivalent number of shares of Issuer common stock, or, at the Issuer's election, cash or a combination of cash and Issuer common stock. The RPSRs vest if the applicable performance metric is satisfied for the relevant measurement period. Grants awarded pursuant to Rule 16b-3(d).
F4	The RPSRs acquired include (i) 2,961.43 vested RPSRs with respect to the measurement period ended 12/31/23 acquired due to settlement of the RPSRs granted under the LTISP on 2/16/21 that resulted in settlement at 141% of the target award; and (ii) 5,133 unvested RPSRs granted under the LTISP on 2/14/24 with a measurement period ending on 12/31/26. A total of 10,148.43 shares were issued in settlement of the 2021 RPSRs with a measurement period that ended 12/31/23, and the target award amount of 7,223 RPSRs was previously reported in connection with the grant of the 2021 RPSRs.
