Northrop Grumman stock holds steady ahead of October earnings update

Northrop Grumman stock (ISIN US6668071029) finished the regular New York Stock Exchange session at USD 528.10 on September 17, 2026, marking a modest 0.50% decline from the prior close according to Ad-hoc-news. For investors, the next major checkpoint is the company’s third quarter 2026 earnings release scheduled for October 20, 2026 before the market opens, a date that will bring updated figures on revenue, profitability and guidance as highlighted by Ad-hoc-news. The defense and aerospace group enters this reporting date after delivering mid single digit revenue growth in its most recent results.

Recent earnings show mid single digit growth

According to a recent earnings overview on Yahoo Finance published in mid September 2026, Northrop Grumman reported revenues of USD 10.88 billion in its latest quarter, representing an increase of 5.1% year on year. The article notes that this quarterly revenue figure came in about 0.5% above analysts’ expectations, indicating a modest beat against consensus and underlining that customer demand across the company’s aerospace and defense programs remains solid. For investors, a 5.1% rise in revenue to USD 10.88 billion versus the prior year’s level provides a concrete signal that growth is continuing, even if at a measured pace.

The same Yahoo Finance analysis highlights that Northrop Grumman’s management issued full year earnings per share guidance that exceeds analysts’ expectations, alongside an impressive beat of organic revenue estimates. While the article does not quote a specific EPS number, the characterization of guidance above consensus suggests that management is positioning the business for continued earnings growth, supported by its backlog and program ramp ups. For shareholders, guidance running ahead of the Street is a key support for the stock’s valuation heading into the October 20, 2026 earnings release, when the company will have to show whether this optimism is justified by actual margin and cash flow development.

Stock trades below 52 week high with large cap valuation

Market data snapshots show that Northrop Grumman stock is trading below its recent highs but still at a substantial large cap valuation. As of September 19, 2026, Investing.com quotes the stock at USD 527.39, with the same portal listing a prior close of USD 527.39, a day range between USD 519.90 and USD 528.27 and a 52 week range from USD 479.02 to USD 774.00, all on the New York Stock Exchange as reported by Investing.com. This places the current price of USD 527.39 clearly above the 52 week low of USD 479.02 but far below the 52 week high of USD 774.00, suggesting that the shares have room to recover if earnings and defense spending trends support a stronger valuation.

A separate snapshot from Robinhood cites a price of USD 521.50 for Northrop Grumman on September 18, 2026, with that session’s trading range between USD 519.92 and USD 527.00 and a price to earnings ratio of 16.61. The same overview lists a market capitalization of USD 74.09 billion, underscoring Northrop Grumman’s status as a large cap defense and aerospace company. In percentage terms, the price of USD 521.50 sits about 0.3% above the intraday low of USD 519.92 and 1.0% below the high of USD 527.00 for that day, illustrating relatively tight trading around the low USD 520s as investors await the next set of quarterly figures.

Monthly performance and upcoming earnings date frame investor expectations

Beyond daily moves, Northrop Grumman’s recent performance over the past month has been mixed within the broader theme of space and defense stocks. An overview of space related shares by INDmoney covering the period from August 19, 2026 to September 19, 2026 shows that Northrop Grumman recorded a monthly change of minus 6.00% in one section of the data and minus 11.06% in another, reflecting that the stock has moved lower over that time span. The same table positions Northrop Grumman alongside peers such as Boeing and Lockheed Martin, with these defense and aerospace names also experiencing negative monthly performance in parts of the period. For investors, this pullback of between roughly 6% and 11.06% over a month offers both a reminder of sector volatility and a potential opportunity, depending on confidence in the upcoming earnings trajectory.
