| About EOG Resources, Inc. |
| EOG Resources, Inc. is a crude oil and natural gas exploration and production company. It explores, develops, produces, and markets crude oil, natural gas liquids (NGLs) and natural gas primarily in major producing basins in the U.S., the Republic of Trinidad and Tobago (Trinidad) and, from time to time, selects other international areas. Its operations are located in the basins of the U.S. with a focus on crude oil and, to a lesser extent, natural gas plays. It is focused on the Wolfcamp, Bone Spring, and Leonard plays. The South Texas area includes its Eagle Ford play and its Dorado gas play. We show 67 historical shares outstanding datapoints in our EOG shares outstanding history coverage, used to compute EOG market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing EOG market cap history over the course of time is important for investors interested in comparing EOG'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 EOG versus a peer is one thing; comparing EOG 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 EOG can fluctuate over the course of history. With this page we aim to empower investors researching EOG by allowing them to research the EOG market cap history. |
