Norfolk Southern shares have gained 13.1% to $311.61 over six months, outperforming the S&P 500 by 7.5%. However, concerns remain about the railway company's long-term performance. The company's revenue grew at just 4.5% annually over the past five years, falling short of industrial sector benchmarks. Operating margin declined by 4.1 percentage points during this period, raising questions about expense management despite revenue growth. Free cash flow margin also dropped 8.4 percentage points over five years, potentially signalling increasing capital intensity. Despite recent momentum, Norfolk Southern's trailing 12-month operating margin of 35.8% and free cash flow margin of 18.1% suggest profitability challenges. Trading at 26.3× forward price-to-earnings, the stock appears fully valued.
