| About Union Pacific Corp |
| Union Pacific Corporation is a railroad operating company in the U.S.. Co. operates through its principal operating company, Union Pacific Railroad Co. (UPRR). It connects over 23 states in the western two-thirds of the country and maintains coordinated schedules with other rail carriers to move freight to and from the Atlantic Coast, the Pacific Coast, the Southeast, the Southwest, Canada, and Mexico. Its Railroad's diversified business mix includes Bulk, Industrial, and Premium. Its Bulk shipments consist of grain and grain products, fertilizer, food and refrigerated, and coal and renewables. We show 68 historical shares outstanding datapoints in our UNP shares outstanding history coverage, used to compute UNP market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing UNP market cap history over the course of time is important for investors interested in comparing UNP's market cap history versus its peers. Many "beginner" or "novice" investors will look at one stock trading at a price of $10 per share and another trading at a price of $20 per share and think the latter company is worth twice as much. Of course, that is a completely meaningless comparison without also knowing how many shares outstanding there are for each of the two companies, and then calculating their respective market caps. Comparing the share price of UNP versus a peer is one thing; comparing UNP market cap versus a peer is a completely different story. Furthermore, via fluctuation both in per-share price and in the number of shares outstanding (via issuance of new shares over time, the repurchase of existing shares), the market cap for a company like UNP can fluctuate over the course of history. With this page we aim to empower investors researching UNP by allowing them to research the UNP market cap history. |
