Based on trailing twelve-month data, NOC has earnings per share of N/A and trades at a PE ratio of N/A. These are key inputs for stock valuation using the PE ratio method.
The trailing twelve-month PE ratio of NOC reflects how much investors pay per dollar of Northrop Grumman Corporation's earnings. This metric is most useful when compared to Aerospace & Defense peers and the company's own historical range.
Whether NOC is overvalued depends on comparing its PE ratio to Aerospace & Defense peers, historical averages, and growth expectations. A PE above the sector average may indicate overvaluation, but high-growth companies often command premium multiples. Consider pairing PE analysis with a DCF model for a more complete picture.
To value Northrop Grumman Corporation using PE: (1) Compare the current PE against the Aerospace & Defense median to assess relative pricing, (2) check the PEG ratio to adjust for growth expectations, (3) review the 5-year PE range to identify where the stock sits historically, and (4) estimate fair value by multiplying a target PE by forward EPS estimates. This relative approach complements DCF's absolute valuation.
The PEG ratio divides the PE ratio by the expected earnings growth rate, providing a growth-adjusted valuation metric. A PEG below 1.0 may indicate undervaluation relative to growth, while above 2.0 may suggest overvaluation. PEG is most reliable for companies with stable, predictable earnings growth.
PE ratio gives a quick relative read — how NOC is priced versus Aerospace & Defense peers. DCF provides an absolute value based on projected free cash flows. For NOC, with a strong ROE of 28.1%, both methods are worth using — PE for a market-relative check, DCF to stress-test whether fundamentals justify the price. Each method has blind spots: PE ignores capital structure and cash flow quality, while DCF is sensitive to growth and discount rate assumptions.
