UNP — Union Pacific Corporation

As of 2026-08-27, the market is leaning bullish: UNP beat Q2 estimates with $3.36 diluted EPS on record $6.864B revenue, improved adjusted operating ratio to 59.2%, and raised full-year 2026 EPS growth guidance to high-single digits. Sell-side targets were raised by several banks, the FMP consensus rating is Buy with a $330.50 average price target, and the stock is trading just below its 52-week high.

The trend is inflecting upward after a flat 2025. Revenue growth went from -0.6% YoY in Q4 2025 to +3.2% in Q1 2026 and +11.5% in Q2 2026, with Q2 revenue of $6.864B a record. EPS followed: $2.87 in Q1 2026, then $3.36 in Q2 2026. TTM operating margin is roughly 39.9% and net margin 28.8%, while Q2 FCF jumped to $2.203B from $1.397B a year earlier. This is an acceleration, not a one-off blip, though sustaining +11% organic revenue growth is unlikely.

As of 2026-08-27, UNP is expensive on its own tape. TTM P/E is 24.9x and forward P/E is about 23.5x using consensus next-FY EPS of $13.07; P/S is 7.2x versus the 6.05x five-year average, and PEG is 3.5x. The 40% operating margin and 38.7% ROE justify a premium to the 21.4x five-year P/E, but the current price already embeds that premium, so the valuation leaves little margin of safety.

As of 2026-08-27, the stock has rallied from a $210.84 52-week low to $307.67, and a meaningful part of that move is multiple expansion rather than earnings alone. At roughly 23.5x forward EPS, the market is paying for continued high-single-digit EPS growth plus potential merger optionality. If Q3 confirms the guidance and the STB process stays constructive, estimates can carry the stock; if volumes stall, the same multiple could compress quickly.

As of 2026-08-27, RSI-14 is 63.32, so momentum is positive but not yet overbought. Price is 2.8% above the 20-day, 6.3% above the 50-day, and 19.2% above the 200-day moving average. The trend is up, but after a 19% run above the 200-day, the entry timing is poor without a pullback.

• Improving industrial/freight cycle is supporting rail volumes and pricing power.
• Interest rates remain a swing factor for a capital-intensive railroad with ~$29B of long-term debt.
• The STB review of the proposed UNP-NS merger is the dominant regulatory overhang and potential catalyst.
• Labor inflation and fuel costs can pressure the operating ratio if volume growth fades.

• Q3 2026 earnings in late October 2026, confirming high-single-digit EPS growth and operating-ratio progress.
• STB procedural milestones and eventual mid-2027 decision on the Norfolk Southern merger.
• Additional analyst estimate revisions and continued dividend/buyback capital returns.

• Merger delay, denial, or costly STB conditions; rival railroads are actively opposing it.
• Freight/industrial volume downturn or pricing slump.
• Execution miss on the operating ratio after the stock has already priced in continued improvement.
• Multiple compression from a rich starting valuation if EPS growth decelerates.

UNP is a best-in-class rail franchise with accelerating revenue, strong cash conversion, and an improving operating ratio, but at $307.67 it is priced for continued perfection. It is a quality compounder to own on pullbacks, not a clear bargain at this level; the pending merger is upside optionality, not the base case.

I applied a 24.0x justified forward P/E to consensus next-FY EPS of $13.07, a deliberate ~12% premium to UNP's 21.4x five-year average P/E to reflect its improved operating ratio, strong cash conversion, and high-single-digit EPS guidance. That yields $313.70 as a reasonable intrinsic value as of 2026-08-27.
