What SemGroup does

SemGroup Corporation (NYSE: SEMG) is a publicly traded midstream energy services company headquartered at 6120 South Yale Avenue, Tulsa, Oklahoma, with approximately 1,100 employees worldwide operating in the United States, Canada, Mexico, and the United Kingdom. The company provides diversified services — gathering, transportation, processing, storage, distribution, terminalling, and marketing — across crude oil, natural gas, natural gas liquids, refined products, residual fuel oil, and asphalt. Its asset base includes approximately 3,900 miles of pipeline and 19 million barrels of storage capacity, organized through operating subsidiaries HFOTCO (refinery-facing oil terminal), Rose Rock (crude oil midstream in the Mid-Continent), SemGas (natural gas gathering and processing including the STACK Canton Pipeline), SemCAMS (Alberta sour gas processing with licensed capacity exceeding 1.9 Bcf/day), and SemLogistics (UK petroleum storage); SemMaterials Mexico was divested in early 2018 for approximately $70 million. Technical differentiators include SemCAMS' zero sulphur emissions sour gas processing and the $500 million three-pipe Maurepas Pipeline serving Gulf Coast refineries.

SemGroup earns revenue through two streams. The dominant stream is fee-based recurring midstream services priced via long-term, multi-year contracts featuring dedicated acreage dedications and take-or-pay minimum volume commitments, which anchor contracted cash flow visibility regardless of commodity price moves. The secondary stream is transactional product sales generated by purchasing, selling, and marketing crude oil, natural gas, and related petroleum products. The go-to-market is sales-led and B2B, targeting upstream oil and gas producers in key shale and unconventional plays (Mid-Continent/STACK, Western Canadian Sedimentary Basin Montney, Gulf Coast), with new business acquired through strategic relationships and contractual acreage dedications rather than through digital or mass marketing channels.

In fiscal 2016, the company reported total revenues of approximately $1.33 billion; Q2 2017 revenues were $473.1 million with Adjusted EBITDA of $65.4 million, against 2017 capital expenditure guidance of approximately $575 million (including $75 million of HFOTCO growth projects and $60 million of maintenance). The company was founded in 2000 (firmographic record) / reorganized into its current public form in 2007, and has since executed the Rose Rock Midstream acquisition (September 2016), the HFOTCO acquisition (July 2017), the Maurepas Pipeline completion (2017), and a $350 million 7% Series A Convertible Preferred private placement (January 2018) with Warburg Pincus, CIBC Atlantic Trust, and Tortoise Capital Advisors.
