Northrop Grumman Corporation (NOC) Down 4.5% — Should I Cash Out While I Can?
Northrop Grumman Corporation (NOC) is under heavy pressure this Wednesday, last changing hands at $481.76, down $22.85 from the prior close of $504.61. The decline deepens a long slide for the defense contractor. NOC now trades roughly 37.8% below its 52-week high of $774.00, reached on March 3, 2026. That gap of nearly $300 per share shows how much investor confidence has eroded over the past seven months.
Volume stands at about 401,109 shares with the session still underway, compared with a 90-day average of roughly 891,474. That puts turnover at under half of a typical full day so far.
Why Northrop Grumman Corporation Price is Moving Lower
The driver is company-specific. On September 29, the U.S. Navy selected Boeing (BA) over Northrop Grumman for its F/A-XX next-generation fighter program. The award is a full-scale development contract worth more than $20 billion, covering test aircraft along with ground, airworthiness, systems, and weapons testing. Reuters reported Northrop shares down 3.5% in extended trading after the news, while Boeing rose 2.25%. The losses carried into Wednesday's regular session. The defeat costs Northrop a chance to become prime contractor on a franchise program expected to enter production in the 2030s. It also hands Boeing another major next-generation fighter platform, which reshapes the competitive balance in military aviation for years to come.
The broader tape rules out a market-wide explanation. The S&P 500 slipped only 0.17%, while Boeing gained 1.78% on the win. Lockheed Martin Corporation (LMT), Northrop's closest defense peer on the list, is down just 0.12%. Emerson Electric Co. (EMR) is off a similarly modest 0.11%. A drop of more than 4.5% in a $71.69 billion contractor, against that backdrop, points squarely at the F/A-XX outcome.
The loss lands on a fundamental picture that was already mixed. Northrop's Q2 report on July 21 beat expectations on the headline numbers. Adjusted EPS came in at $7.68 against a $6.82 estimate, and revenue of $10.88 billion topped the $10.8 billion consensus while rising 5% year over year. Beneath those beats, however, operating income fell 23% and operating margin narrowed to 10.1% from 13.8%. That kind of compression makes the loss of a high-value future program sting more. Management raised 2026 sales guidance to $43.75 billion to $44.25 billion and adjusted EPS guidance to $28.60 to $29.10. Those targets remain intact, since F/A-XX was a long-horizon opportunity rather than a near-term revenue line. Investors will get the next read on margins and program execution when Northrop reports third-quarter results before the market opens on October 20, 2026.
What is the Northrop Grumman Corporation Rating - Should I Sell?
Weiss Ratings assigns NOC a C rating. Current recommendation is Hold. That rating captures a defense prime with sturdy underlying operations whose stock has delivered a painful experience for shareholders this year. A Hold is not a sell signal, but it counsels patience over aggressive buying.
The operating side of the scorecard is uniformly strong. Northrop is rated Excellent on the Growth Index, the Efficiency Index, and the Solvency Index. The Growth rating is backed by 5.07% revenue growth and a raised full-year sales outlook. For a contractor of this scale, that is steady expansion rooted in multi-year government budgets rather than cyclical demand. The Excellent Efficiency rating is supported by a 26.96% ROE, a high return for a capital-intensive manufacturer building bombers, satellites, and missile systems. The 10.48% profit margin looks modest by comparison, and the second-quarter margin squeeze to 10.1% shows it is under some strain. The Excellent Solvency rating suggests the balance sheet can absorb setbacks like the F/A-XX loss without financial stress. That strength also supports the 2.35% dividend yield.
Where the picture turns is on the market-facing dimensions. The Total Return Index and the Volatility Index are both rated Weak. A stock sitting nearly 38% below its March peak has not rewarded holders over the measurement period, which explains the Total Return rating. Today's slide on a single contract decision shows why the Volatility Index is not rated higher: one competitive outcome can move this stock by more than 4%. These two ratings are what hold the overall grade at C despite the excellent fundamentals. A forward P/E of 16.07 against trailing EPS of $31.47 suggests the market is already pricing in some of that uncertainty.
Within the Industrials sector, Northrop Grumman trails a cluster of peers. Lockheed Martin Corporation (LMT, C+), Deere & Company (DE, C+), and Emerson Electric Co. (EMR, C+) all carry slightly stronger risk/reward profiles in the Weiss framework. For NOC, the gap with Lockheed is the most telling, since the two compete directly for many of the same Pentagon dollars.
About Northrop Grumman Corporation
Northrop Grumman Corporation (NOC) is an Industrials company and one of the largest aerospace and defense contractors in the world. Headquartered in Falls Church, Virginia, the company took its current form through the 1994 combination of Northrop and Grumman, two aviation pioneers with roots in the 1920s and 1930s. It operates through four segments: Aeronautics Systems, Defense Systems, Mission Systems, and Space Systems. The U.S. government, primarily the Department of Defense and intelligence agencies, is its dominant customer, supplemented by international allies and commercial space customers.
The company's portfolio spans some of the most strategically important programs in American defense. In aeronautics, Northrop builds the B-21 Raider stealth bomber, the E-2D Advanced Hawkeye airborne early-warning aircraft, and the RQ-4 Global Hawk and MQ-4C Triton unmanned surveillance platforms. It also supplies major structures and radar systems for the F-35. Its Space Systems segment produces satellites, solid rocket motors, and the Cygnus resupply spacecraft, and it was prime contractor on the James Webb Space Telescope. Northrop is also leading development of the Sentinel intercontinental ballistic missile. In Mission Systems, it supplies advanced radars, electronic warfare systems, and the Integrated Air and Missile Defense Battle Command System.
Northrop's competitive advantages come from deep expertise in stealth, space, and strategic deterrence. These are areas where the technical barriers, security clearances, and decades of classified program experience are extraordinarily difficult for rivals to replicate. Long-duration contracts such as the B-21 and Sentinel provide revenue visibility stretching well into the next decade. The company still competes in a winner-take-most procurement environment against Lockheed Martin, Boeing, RTX, and General Dynamics. There, losing a single franchise competition can reshape its long-term growth trajectory.
Investor Outlook
Northrop Grumman Corporation (NOC) carries a Weiss Rating of C (Hold). The F/A-XX loss adds a long-term competitive setback to a stock already well off its highs, even though the underlying fundamentals remain strong. Investors should watch the October 20 Q3 report for signs that operating margins are recovering from the 10.1% posted last quarter. They should also watch whether management reaffirms its $28.60 to $29.10 adjusted EPS guidance and explains how it plans to offset the lost fighter opportunity.
