Mammoth Energy Services
Mammoth Energy Services launched in 2014 under CEO Arty Straehla, a veteran of the oilfield services industry, and completed its initial public offering on the Nasdaq in October 2016. The company traces its roots to the shale basins of Oklahoma and West Texas, but its corporate structure — a public C-corp with diversified infrastructure service lines — gives it a different operating posture than privately held, family-backed energy service providers operating in the same basins. Mammoth operates through three primary segments: pressure pumping and proppant logistics for well completions, directional drilling and related oilfield services, and infrastructure engineering that includes electrical transmission and distribution work. The infrastructure division gained national visibility in 2017 and 2018 when it secured a series of contracts with the Puerto Rico Electric Power Authority for grid restoration following Hurricane Maria, with total contract value exceeding $2 billion (per SEC filings). Direct hydrocarbon-facing operations route frac sand from the company's Northern White sand mines in Wisconsin to completion sites in the Permian Basin, Eagle Ford, and SCOOP/STACK plays. As of its most recent public reporting, Mammoth employed over 1,200 people and maintained active pressure pumping spreads operating primarily in the Permian Basin and Mid-Continent regions. The company lacks the multi-family-office architecture or co-investment club structure common among private energy family offices; instead, it accesses institutional capital through public equity and debt markets. In February 2024, the company disclosed it had resumed pressure pumping services for a major integrated oil company in the Permian Basin after a multi-quarter pause, signaling renewed deployment of its frac fleet (per the firm's Q4 2023 earnings release). Mammoth's structural differentiator is its hybrid exposure: it combines the cyclical upside of completions-linked oilfield services with the regulated, long-cycle cash flows associated with electrical grid engineering and storm-hardening work. That pairing means the company's backlog spans both E&P capex cycles and utility rate-based infrastructure spending — a rare combination for a publicly traded small-cap energy services firm.

Frequently asked questions
Who runs investment and capital allocation decisions at Mammoth Energy Services?
Arty Straehla serves as CEO and a director. Mark Layton is Chief Financial Officer. Because Mammoth is a publicly traded operating company rather than a family office or fund, capital allocation — including rig reactivations, sand mine investments, and infrastructure contract pursuit — runs through the C-suite and board. Major strategic moves, including the decision to go public in 2016 and the subsequent Puerto Rico grid contracts, occurred under Straehla's leadership.
How does Mammoth Energy Services source its revenue and what drives the business?
Revenue splits across two very different cycles. Pressure pumping and sand logistics revenue tracks North American E&P capital spending, particularly in the Permian Basin and Mid-Continent. Infrastructure services revenue is driven by utility spending on transmission, distribution, and storm-hardening contracts. The Puerto Rico contracts represented an extraordinary, lumpy concentration, but the segment also serves continental US utilities.
Does Mammoth operate as an investment firm or a pure operating company?
Mammoth is a pure operating company — it owns and runs frac fleets, sand mines, drilling rigs, and electrical infrastructure crews. It does not manage external capital, make LP commitments, or operate a co-investment vehicle. Its only interface with institutional investors is as a public company whose shares trade on the Nasdaq under ticker TUSK.
What is Mammoth's connection to the Puerto Rico Electric Power Authority and why does it matter?
Following Hurricane Maria in 2017, Mammoth's infrastructure subsidiary entered a series of contracts with PREPA for grid restoration work. The total contract value exceeded $2 billion (per SEC filings), transforming Mammoth from a regional oilfield services provider into a company with a nationally visible infrastructure backlog. Collections on those contracts have been a recurring source of working-capital volatility and regulatory scrutiny.
Which basins and geographies does Mammoth's pressure pumping fleet serve?
The company operates pressure pumping spreads primarily in the Permian Basin (West Texas and southeastern New Mexico) and the Mid-Continent region, with proppant logistics supporting deliveries into the Eagle Ford and SCOOP/STACK formations as well. Its frac sand mines are located in Wisconsin's Northern White sand formation.
Is Mammoth Energy Services related to any family office or legacy wealth vehicle?
No. Mammoth was founded in 2014 by a group of oilfield services executives and went public in 2016. It is not associated with a single-family office, multi-family office, or legacy wealth pool. Its capital structure is conventional public-company equity and debt.
What is Mammoth's known posture toward the energy transition?
Mammoth actively participates in the energy transition through its infrastructure division, which performs electrical grid engineering, transmission, and distribution work — the kind of spending required to connect renewable generation to load centers. At the same time, its oilfield services segment remains fully exposed to hydrocarbon completions activity, making the company a hybrid energy play rather than a pure-play renewables or green infrastructure bet.
