September 16, 2026 in numbers
Northrop Grumman Corporation (ISIN US6668071029, NYSE: NOC) ended trading on September 16, 2026 at USD 530.78 on its primary NYSE listing, following an after-hours indication of USD 526.70 later that evening, with the regular-session move marking a modest 0.09% decline from the prior close. Per recent NYSE quote data, the previous session on September 15, 2026 saw the shares close at USD 527.90 after gaining USD 8.93, or 1.72%, indicating that the stock has added nearly USD 2.88 over the two-day span while the S&P 500 turned lower over the same period. At the September 16, 2026 closing level, Northrop Grumman remains below several valuation markers, including a fair value estimate of about USD 643.62 referenced in a discounted cash flow analysis and a consensus analyst price target near USD 662, underscoring a sizeable gap between the latest trading price and longer-term valuation anchors.
Earlier in the week, sentiment around the defense group was buoyed by fresh analyst coverage and contract news. As Ad-hoc-news reported on September 16, 2026, Guggenheim initiated coverage of Northrop Grumman with a Buy rating and a USD 612 price target, while the US Army awarded the company a USD 4.8 billion contract for its Common Infrared Countermeasure system, contributing to a record backlog of USD 104.7 billion and higher 2026 sales and earnings guidance. In parallel, valuation-focused commentary cited a fair value around USD 643.62 per share against a recent close just above USD 531, highlighting roughly 20% implied upside and framing the stock as potentially undervalued relative to its expanded backlog and updated guidance.
Outlook today and in coming days
Today, September 17, 2026, Northrop Grumman heads into the open against the backdrop of a softer US equity tape following a Federal Reserve rate hike that pressured major indices in the last session. As The Motley Fool noted on September 16, 2026, stocks slipped after the Fed raised interest rates, a move that can influence defense names through its impact on discount rates and broader risk appetite. Against that macro setting, investors today are likely to weigh the recently announced USD 4.8 billion Army contract and Guggenheim Buy rating alongside the Fed-driven volatility, with the valuation gap to targets such as USD 612 and USD 643.62 providing context for how the shares trade into the next few sessions.
