Union Pacific Corporation (UNP) is a giant in the railroad industry, essentially acting as a vital artery for the American economy.

The Business Model (How They Make Money)

Union Pacific makes its money by transporting a huge variety of goods across a vast network of railway tracks in the western two-thirds of the United States. Think of them as a massive, efficient trucking company, but on rails. They charge businesses to move their products from one place to another.

Their main sources of income come from different types of freight they carry. In fiscal year 2025, their total revenue was $24.51 billion. Here's a breakdown of where that money came from:

• Industrial Products: This was their biggest segment, bringing in $8.60 billion, which was about 35.1% of their total revenue. This includes things like chemicals, plastics, metals, and construction materials.
• Bulk Products: This segment generated $7.59 billion, making up about 30.95% of their total revenue. This category covers large quantities of goods like grain, fertilizer, and coal.
• Premium Products: This segment contributed $7.03 billion, or roughly 28.68% of their total revenue. This typically includes time-sensitive goods like finished automobiles and containers filled with various consumer products (often called "intermodal" freight).
• Other Revenues: Smaller portions of their revenue come from things like "Accessorial Revenues" ($475 million, 1.94%) which are charges for services like storing freight cars, and "Other Subsidiary Revenues" ($718 million, 2.93%).

In the second quarter of 2026, Union Pacific reported total operating revenue of $6.9 billion, a 12% increase compared to the second quarter of 2025. Freight revenue also increased by 12% in the same period.

The Metrics That Matter Most

For a company like Union Pacific, which relies on a massive physical network to move goods, certain financial numbers give us the best picture of its health and efficiency.

1. Revenue: This is the total amount of money the company brings in from its services before any expenses are taken out. For Union Pacific, it tells us how much business they are doing by moving freight. A growing revenue number means more goods are being shipped on their rails, indicating a healthy demand for their transportation services and overall economic activity. In the second quarter of 2026, Union Pacific's operating revenue was $6.9 billion, a 12% increase from the second quarter of 2025.

2. Operating Income: This metric shows how much profit the company makes from its core business operations after paying for things like fuel, employee wages, and maintenance, but before accounting for interest and taxes. For a railroad, it's a crucial measure of how efficiently they are running their trains and managing their vast network. A higher operating income suggests they are doing a good job of controlling costs while generating revenue. Union Pacific's operating income for the second quarter of 2026 increased 9% to $2.8 billion.

3. CapEx (Capital Expenditures): This refers to the money a company spends to buy, maintain, or improve its physical assets, like tracks, locomotives, and rail yards. For Union Pacific, CapEx is incredibly important because their business is their infrastructure. They need to constantly invest in their network to keep it safe, efficient, and capable of handling more freight. It's not just about growth; it's about maintaining their core asset. Union Pacific has a capital plan of $3.3 billion for 2026, indicating their ongoing investment in their infrastructure.

4. Free Cash Flow: This is the cash a company generates after paying for its operating expenses and capital expenditures. Think of it as the leftover cash that the company can use for things like paying down debt, buying back its own stock, or giving money back to shareholders through dividends. For a mature company like Union Pacific, strong free cash flow shows that their business is not only profitable but also generating plenty of actual cash, which is a sign of financial strength. Union Pacific's year-to-date free cash flow for the first half of 2026 increased to $1.812 billion, up from $1.105 billion in the first half of 2025.

How to Value This Company

For a capital-intensive business like Union Pacific, which owns a lot of physical assets and has significant debt, the EV/EBITDA (Enterprise Value to Earnings Before Interest, Taxes, Depreciation, and Amortization) ratio is often the most insightful valuation metric.

Here's why and how to think about it:

• What it is:
  • Enterprise Value (EV): This is like the total price tag of the entire company, including its stock market value, plus its debt, minus any cash it has. It gives a more complete picture of a company's worth than just its stock price, especially for businesses with a lot of debt.
  • EBITDA: This stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It's a way to look at a company's operating profit before accounting for certain non-cash expenses (like depreciation, which is the accounting way of spreading the cost of an asset over its useful life) and the impact of financing decisions (interest and taxes).
• Why it matters for Union Pacific: Railroads have huge amounts of physical assets (tracks, trains) that wear out over time, leading to large depreciation expenses. They also often carry a lot of debt to finance these assets. EV/EBITDA helps you compare Union Pacific to other similar companies by stripping out the effects of different accounting choices for depreciation and different debt levels. It focuses on the cash-generating ability of the core business.
• How to use it: You would compare Union Pacific's EV/EBITDA ratio to that of its competitors or its own historical average. If Union Pacific's EV/EBITDA is lower than its peers or its own past, it might suggest the stock is "cheap" or undervalued. If it's higher, it might be considered "expensive." As of June 30, 2026, Union Pacific's adjusted debt to adjusted EBITDA was 2.5x, based on an adjusted EBITDA of $12.719 billion.
