Citi upgrades Union Pacific as railroad stock looks 'too compelling to ignore'

Citi upgraded Union Pacific (UNP) to Buy from Neutral, setting a $251 price target, driven by increased clarity on the Norfolk Southern merger — now with a 65-70% approval likelihood — recent share price weakness, and strong operational execution. Analyst Ariel Rosa emphasized that UNP remains compelling even if the merger fails, trading at an attractive 18x forward earnings multiple, a significant discount to the S&P 500, while maintaining high operational performance.

Analysis

Citi has upgraded Union Pacific (UNP) to Buy from Neutral, raising its price target to $251, which represents approximately 17% potential upside from its prior close. The upgrade is driven by three primary factors: increased clarity on the proposed merger with Norfolk Southern, with the probability of a clean approval now estimated at 65-70%; a more attractive valuation following a 6% year-to-date decline in the share price; and strong operational execution that supports a positive outlook for 3Q25 earnings and post-merger integration success. Crucially, the analyst's bull case does not hinge solely on the deal's approval. On a standalone basis, Union Pacific is presented as compelling, trading at around 18 times forward earnings, which is a significant discount to the S&P 500's 24.7 multiple and below UNP's own long-term average P/E ratio. This suggests a valuation floor and an independent investment thesis even if the merger, which still faces a 'contentious' review, were to fail.

Key Decisions for Investors

• Investors could view Union Pacific as having a dual-catalyst investment profile, offering potential upside from progress in the Norfolk Southern merger alongside a defensive valuation based on its standalone fundamentals.
• Given the stock's forward P/E of 18x—a discount to both the market and its historical average—the recent 6% pullback in 2025 may represent an attractive entry point for initiating or adding to a position.
• It is crucial to monitor developments in the regulatory review of the Norfolk Southern merger, as any negative news or imposition of significant constraints could temper the upside case, even with the improved 65-70% approval odds.
