Union Pacific (UNP) Valuation Check as BNSF Seeks Review of Southern Pacific Merger Conditions

Simply Wall St

BNSF Railway’s push for a fresh review of the decades old Union Pacific Southern Pacific merger terms has suddenly put Union Pacific (UNP) back under the regulatory spotlight, and that matters for the stock.

See our latest analysis for Union Pacific.

The renewed focus on merger conditions lands at a time when Union Pacific’s 1 month share price return of 7.41 percent and 90 day share price return of 7.71 percent point to building momentum, even as its 5 year total shareholder return of 30.28 percent reflects steadier long term compounding.

If you are weighing how this regulatory twist fits into the wider transport theme, it could be worth comparing Union Pacific with other leading aerospace and defense stocks that may be reshaping how goods and people move globally.

With earnings still growing and the share price sitting roughly 10 percent below consensus targets, is Union Pacific quietly undervalued ahead of a regulatory shake up, or is the market already pricing in every mile of future growth?

Another Take on Valuation

On a simple price to earnings lens, Union Pacific looks less generous. Its 20x multiple is richer than close peers at 17.9x, even if it still trades below the US Transportation average of 30.6x and near a fair ratio of 21.9x. Is that thin gap enough compensation for rail specific risks?
