Which Megamerger Side Should You Own?

Union Pacific (NYSE: UNP) and Norfolk Southern (NYSE: NSC ) sits on the fringes of the largest railroad deal in US history: a stock transaction of $320 per share and an $85 billion enterprise value. The Surface Transportation Board (STB) accepted the revised application on May 28, 2026, and suspended the review to request additional information. That background is reshaping how investors should read the companies’ Q1 results.

Western Network Integrated. Eastern Held the Line.

Union Pacific delivered adjusted EPS of $2.93 on revenue of $6.22 billion, with an adjusted operating margin of 59.9%. The bulk was higher: coal and renewables jumped 17%, grains rose 11%, and fertilizers rose 12%. Whereas, intermodal decreased by 6%. CEO Jim Vena said the team “rechallenged what’s possible on our main rail line,” and performance data backed him up, with a record-breaking 19.7 hour stay.

Norfolk Southern posted adjusted EPS of $2.65 on flat revenue of $3.00 billion. The eastern freight company posted a tough adjusted operating margin of 68.7%, and GAAP revenue fell to $547 million as Eastern Ohio’s $185 million return in Q1 2025 turned into $10 million in total costs. CEO Mark George praised the team for “working with discipline amid fluctuating volumes, severe winter weather, and a rapidly changing economic environment.”

Discovery Discipline vs. Target Selection

Shares of Norfolk Southern closed at $304.96, leaving about a 5% spread on the $320 deal price. Union Pacific, at $262.64, is up 13.5% year to date, even after a 3.9% drop on the STB break. Both companies have paused the acquisition to save money on the deal.

STB Review is an Outstanding Risk

Opponents retreat hard. BNSF and CN filed motions to compel UP and NS to produce additional merger documents, CPKC CEO Keith Creel warned that the deal would create a duopoly and prompt more mergers, and CSX CEO Steve Angel opposed the merger at a shareholder meeting on May 16, 2026. The deadline for further information is July 27, 2026, with a decision expected the last in late 2026 or 2027. Activist pressure on CSX from Ancora ensures this is a restructuring of the sector.

A historic $85 billion rail merger has just hit a roadblock. See why Union Pacific is moving ahead while Norfolk Southern faces a high-profile ‘arbitrage’ gamble.

The Case of Union Pacific Over Norfolk Southern

Union Pacific may be a more attractive option. The figures are asymmetric. Norfolk Southern is essentially a 5% arbitrage with regulatory tail risk; if STB blocks the deal or seeks a bigger split, the stock is likely to return to its independent fair value, well below the $323.38 high reached on May 27. Union Pacific continues to rally anyway. Vena’s team is targeting mid-single-digit EPS growth in 2026 and low-to-single-digit CAGR in 2027, with a 2.1% profit underpinned by a rail line that is already nine points stronger in terms of performance than its eastern partner.

For a retirement-minded investor, owning an operator with a better network product and a lower rate of layoffs is a clean call. That view would only change if Norfolk Southern traded significantly below its standalone fair value. At current rates, it doesn’t.
