Organization

We are a master limited partnership founded in Delaware in 1996 and focused on the midstream segment of the crude oil and natural gas industry. Our operations are primarily located in the Gulf of America and in the Gulf Coast region of the United States. We provide an integrated suite of services to crude oil and natural gas producers, refiners and industrial and commercial enterprises. We have a diverse portfolio of assets, including pipelines, offshore hub and junction platforms, barges and other vessels, refinery-related plants, storage tanks, terminals, railcars, rail unloading facilities and trucks. We are owned 100% by our limited partners. Genesis Energy, LLC, our general partner, is a wholly-owned subsidiary. Our general partner has sole responsibility for conducting our business and managing our operations. We conduct our operations and own our operating assets through our subsidiaries and joint ventures.

In the first quarter of 2025, we re-organized our operating segments as a result of the way our chief operating decision maker, who is our Chief Executive Officer (our “CODM”), evaluates the performance of operations, develops strategy and allocates resources, including capital. Our sulfur services business, formerly reported under our soda and sulfur services reporting segment with our Alkali Business (as defined below), is now reported under our onshore transportation and services reporting segment along with our previously reported onshore facilities and transportation segment. As a result of this change, we now manage our businesses through the following three divisions that constitute our reportable segments:

•Offshore pipeline transportation, which includes the transportation and processing of crude oil and natural gas in the Gulf of America;

•Marine transportation, which provides waterborne transportation of petroleum products (primarily fuel oil, asphalt and other heavy refined products) and crude oil throughout North America; and

•Onshore transportation and services, which includes terminaling, blending, storing, marketing, and transporting crude oil and petroleum products, as well as the processing of high sulfur (or “sour”) gas streams for refineries to remove the sulfur, and selling the related by-product, sodium hydrosulfide (or “NaHS,” commonly pronounced “nash”).
