Why Is Norfolk Southern (NSC) Down 2.4% Since Last Earnings Report?

Norfolk Southern (NSC) shares have declined 2.4% since its Q2 2025 earnings report, underperforming the S&P 500, despite reporting an EPS of $3.29 which beat estimates by 7.5% year-over-year due to lower costs. However, railway operating revenues of $3.11 billion missed consensus, and the company subsequently lowered its 2025 revenue growth guidance to 2-3% and adjusted operating ratio improvement expectations. This mixed performance and revised outlook have led to downward estimate revisions and a Zacks Rank #4 (Sell), indicating a negative near-term outlook for the stock.

Analysis

Norfolk Southern's (NSC) recent 2.4% share price decline, which underperformed the S&P 500, is primarily attributable to a downward revision of its full-year 2025 guidance, overshadowing a mixed second-quarter earnings report. While Q2 EPS of $3.29 beat estimates and grew 7.5% year-over-year, this was driven by cost management rather than top-line strength. Railway operating revenues of $3.11 billion missed consensus, increasing a modest 2.2% despite a 3% rise in overall volumes, indicating pricing pressure as total revenue per unit dipped 1%. This pricing weakness was most pronounced in the Coal segment, where a significant 11% drop in revenue per unit offset a 12% volume increase. Consequently, management has tempered its 2025 outlook, lowering expected revenue growth to a 2-3% range (from 3%) and trimming the anticipated adjusted operating ratio improvement to 100-150 basis points (from 150). This revised forecast has triggered downward revisions in analyst estimates and cemented a negative market sentiment, reflected in the stock's Zacks Rank #4 (Sell) and subpar 'D' grades for both Growth and Value.

Key Decisions for Investors

• Investors should weigh the lowered full-year 2025 guidance for revenue and operating ratio more heavily than the Q2 EPS beat, as this forward-looking revision is the key catalyst for the stock's recent underperformance.
• Monitor revenue per unit across all segments, particularly in Coal, as persistent pricing weakness could negate the benefits of volume growth and the company's increased productivity savings target of over $175 million.
• Given the downward trend in analyst estimates, a 'Sell' rating from Zacks, and underperformance relative to peers like Canadian National (CNI), a cautious stance is warranted, and it may be prudent to re-evaluate exposure to NSC in the near term.
