Northrop Grumman Stock Performance Snapshot

Northrop Grumman (NOC) is drawing attention after recent share price moves, with the stock last closing at $528.24. Investors are weighing this level against its mixed shorter term returns and longer term track record.

Over the past month the stock declined 4.2%, and it is down 3% over the past 3 months. Year to date the share price is lower by 9.8%, and the 1 year total return shows a 7.4% decline.

The picture looks different over longer horizons. The 3 year total return is 28.8%, and the 5 year total return is 60.6%. This contrast may encourage you to think about time horizon and risk tolerance when assessing Northrop Grumman stock.

At a market value of about US$74.4b, Northrop Grumman operates across four main segments: Aeronautics Systems, Defense Systems, Mission Systems and Space Systems, each contributing a significant share of overall revenue.

Recent reported revenue is US$42.9b with net income of US$4.5b. Annual revenue growth is 5.7% and annual net income growth is 3.2%. These figures provide context for any assessment of the current share price and the company’s profitability profile.

Northrop Grumman’s operations are heavily weighted to the United States, which accounts for US$36.8b of revenue. Europe contributes US$3.3b, Asia/Pacific US$2.0b and other regions US$0.8b, highlighting a primarily domestic revenue base with additional international exposure.

Within the business, Aeronautics Systems generates US$13.9b of revenue, Mission Systems US$12.7b, Space Systems US$10.8b and Defense Systems US$8.2b, offset by intersegment eliminations. This spread shows how the stock is tied to multiple areas of aerospace and defense activity.

For you as a shareholder, that mix of moves results in a stock with weak recent momentum but solid longer-term total shareholder returns.

Northrop Grumman’s share price has declined 9.8% year to date, and the 1-year total shareholder return is lower by 7.4%, while the 3-year and 5-year total shareholder returns of 28.8% and 60.6% show how earlier gains still shape the bigger picture. Recent share price pressure, including a 4.2% decline over the past month and a 3.1% decline over the last week, indicates that some investors may be reassessing growth expectations or risk around defense spending and program timing at the current US$528.24 level.
