UNION PACIFIC CORP (UNP) stock intrinsic value fair value estimate & owner earnings analysis

Union Pacific owns and runs the largest railroad in the western United States, linking West Coast and Gulf Coast ports, the Powder River Basin coal field in Wyoming, Midwest grain country and the main rail gateways into Mexico. It shares the West with one other large railroad, BNSF. In 2025 about 33% of freight revenue came from bulk traffic (grain, fertilizer, food and coal), 37% from industrial traffic (chemicals, plastics, construction materials, metals, petroleum) and the rest from intermodal containers and finished vehicles; shipments to and from Mexico brought in $2.9 billion. A railroad's right-of-way cannot realistically be rebuilt by anyone else, and that is the source of the business's durability. The pending Norfolk Southern merger. In July 2025 Union Pacific agreed to acquire Norfolk Southern, the large eastern railroad. Each Norfolk Southern share becomes one Union Pacific share plus $88.82 in cash: about 224.8 million new shares and about $20 billion of cash, funded with new borrowing and retained cash. Both sets of shareholders approved the deal in November 2025. It still needs Surface Transportation Board approval; in January 2026 the Board ruled the first joint application incomplete and allowed a revised one, and either side may walk away if the deal has not closed by January 28, 2028. A $2.5 billion fee is payable in either direction in certain termination circumstances. Because Union Pacific is bound to complete the deal if approval comes on acceptable terms, all three cases assume it closes. We credit Norfolk Southern's own demonstrated cash flow and none of the cost savings or new traffic management expects from the combination, because none of that has happened yet. Measured that way, the merger costs Union Pacific owners value: the shares and cash handed over are worth more than the cash flow they acquire. If the deal is blocked or abandoned, Union Pacific on its own works out at about $132 a share in the bear case, $186 in the base case and $230 in the bull case. How we measure earnings. Owner earnings are cash from operations, with working-capital swings removed, minus stock compensation and the capital spending needed to keep the railroad in its present condition. We value the business before its lenders are paid and then subtract what it owes, so the stream we value adds back cash interest. Owner earnings per share rose from $3.82 in 2016 to $9.66 in 2025, but much of that came from buying back about a third of the shares, largely with borrowed money. The cash the railroad produces before interest rose from $6.27 billion in 2019 to $7.07 billion in 2025, about 2% a year, on revenue that was almost unchanged between 2014 ($24.0 billion) and 2025 ($24.5 billion). Price increases have repeatedly been offset by lost volume, mainly coal. We treat nearly all capital spending ($3.4 to $3.8 billion a year recently) as maintenance of track, locomotives and cars. That is well above depreciation of about $2.5 billion, so the earnings level is not flattered. We anchor on 2019 to 2025, the years since the railroad switched to its current scheduled operating plan in late 2018. That switch cut capital spending from $4.3 to $4.7 billion a year to $2.9 to $3.8 billion. The window includes the 2020 shutdown and 2023, when a new national labour agreement and weak volumes cut the stream to $6.24 billion. The median year is $6.87 billion before interest, about $11.57 per current share. In 2025 the stream grew 2.9%; the base case assumes 2.0% in its first year. First-half 2026 net income was about 5% above the prior year with capital spending flat, which supports that level. Norfolk Southern adds about $2.75 billion a year before interest in the base case, taken from its 2021 to 2025 record with the 2023 East Palestine derailment year and 2025 insurance recoveries smoothed out. Base case, $156 a share. The combined stream of $9.62 billion grows 2% a year for ten years, the pace Union Pacific has actually sustained since 2019 through pricing. After that it is held flat in dollars, with no further growth credited, resting on a network that has earned money for more than 150 years. The business is worth about $187.5 billion; it owes about $59.6 billion; owners are left with about $127.8 billion, or $156 on roughly 818.6 million shares after the merger. Bear case, $100 a share. The stream starts at Union Pacific's 2023 low of $6.24 billion plus $2.5 billion for Norfolk Southern, $8.74 billion in total. Integration problems cut it 5% in each of the first two years; Union Pacific's 1996 purchase of Southern Pacific was followed by a service collapse in 1997 and 1998. A freight recession as deep as 2015 and 2016 then hits in years two to four; in that episode Union Pacific's operating income fell 17%, from $8.75 billion in 2014 to $7.27 billion in 2016. The stream bottoms near $6.9 billion, recovers to $8.74 billion by year five and never grows again, as revenue failed to grow from 2014 to 2025. The business is worth about $141.8 billion, it owes $59.6 billion, and owners are left with about $82.1 billion, or $100 a share. Even at the bottom, the stream covers the roughly $3.2 billion of combined annual interest about twice over. Bull case, $201 a share. The stream starts at 2025 levels ($7.07 billion for Union Pacific plus $2.85 billion for Norfolk Southern). It grows 3% a year for ten years, matching Union Pacific's 2025 result, then 1.5% a year for the following ten as pricing keeps running ahead of volume losses, and is flat after that. No merger savings are included. The business is worth about $224.5 billion, it owes $59.6 billion, and owners are left with about $164.8 billion, or $201 a share. Debt. At mid-2026 Union Pacific owed $30.3 billion at face value. Much of it is long-dated, fixed-rate debt with coupons well below today's borrowing costs, so we count it at the $24.7 billion fair value the company discloses. Norfolk Southern's $16.6 billion is counted at face. The $20 billion cash payment is counted in full, and about $1.7 billion of cash beyond operating needs is deducted. No single maturity is large enough to change the outcome, and the combined interest bill of about $3.2 billion compares with a business stream of about $9.6 billion. Future cash is discounted at 6% a year. What could make this wrong: a lasting loss of volume beyond coal, for example intermodal traffic moving to trucks or a break in cross-border trade with Mexico; the regulator attaching merger conditions that change the economics; or a merger that actually delivers real savings, which would be upside these figures leave out. Our previous analysis was made on a different basis, so its figures are not comparable. It also left out the Norfolk Southern merger, which this one includes. Margin-of-safety price. We are fairly confident of the earnings level. Before interest, the stream stayed between $6.2 and $7.3 billion through the 2020 shutdown, the 2022 labour settlement and the 2023 volume slump. The worst plausible outcome is the merger closing into a service breakdown during a freight recession, with about $60 billion of debt outstanding. The hard, irreplaceable network and the size of its cash flow mean the business would survive that, but owners would see years of no progress, and the shares would be worth about $100. The things we are most likely to be wrong about are growth and Norfolk Southern's normal earnings. If the combined stream never grows at all, the shares are worth about $123. If Norfolk Southern's normal earnings are a fifth lower than assumed, they are worth about $143. The price assumes a three-to-five-year holding period. The business pays about $5.43 a share a year in dividends, roughly a 5.7% yield on a $95 price, and it can pay down debt from what it retains. From $95, the median outcome reached within about four years, plus dividends, implies roughly 20% a year, and the bear case value is about equal to that price. That is why the margin-of-safety price is $95.
