Explanation of Responses:

Id	Content
F1	Held in the Northrop Grumman Savings Plan (the "Plan"), a qualified defined contributions plan, as of 2/16/2023. 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 2/16/23 and will vest on 2/17/26.
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) 2,103.15 vested RPSRs with respect to the measurement period ended 12/31/22 acquired due to settlement of the RPSRs granted under the 2011 Long-Term Incentive Stock Plan ("LTISP") on 2/12/20 that resulted in settlement at 135% of the target award; and (ii) 4,669 unvested RPSRs granted under the LTISP on 2/16/23 with a measurement period ending on 12/31/25. A total of 8,112.15 shares were issued in settlement of the 2020 RPSRs with a measurement period that ended 12/31/22, and the target award amount of 6,009 RPSRs was previously reported in connection with the grant of the 2020 RPSRs.
