Mullen Group’s Specialized & Industrial Services segment
Mullen Group’s Specialized & Industrial Services (“S&IS”) segment is comprised of unique businesses in sectors of the Canadian economy that require specialized equipment and services including the natural resources, energy, infrastructure and construction sectors.
Our S&IS segment business units provide a wide range of service offerings including water management, environmental reclamation services, turnaround services and industrial maintenance, services that support the drilling of wells, well servicing and fluid hauling associated with the oil and gas industry in western Canada, along with transportation and logistics services for complex pipeline and industrial projects. Our business units are strategically situated throughout western Canada and operate fleets of highly specialized equipment, generating superior returns on capital employed over the long term.
The S&IS segment is further broken down into three segments: Production Services, Specialized Services and Drilling & Drilling-Related Services.
The segment has approximately 1,500 personnel spread across 15 strategically located business units, whose combined financial performance is highlighted by:
- Contributing about 22.9 percent of Mullen’s annual revenue, according to the company’s 2024 Annual Financial Review.
- Revenue growth from C$362 million in 2020 to C$457.1 million as of Q4 2024.

Certain business units in this category provide full-service offerings to companies utilizing fracking techniques. Service offerings also include industrial cleaning and turnaround services. Mullen Group currently has four business units that provide services in this area.

Cascade Energy Services, founded in 1997, was acquired by Mullen Group in 2008.

Specialized Services
Business units in the Specialized Services category primarily provide services to Canada’s natural resources and infrastructure sectors such as pipeline, construction, petro-chemical, utility & telecom and oil & natural gas, as well as municipalities. Service offerings include dredging and dewatering services, oversize and overweight transportation services, the transportation, stringing and stockpiling of large-diameter oil and natural gas transmission pipe, civil construction, environmental services, industrial cleaning and turnaround services, emergency support services, and OEM parts and service dealer services.

Canadian Dewatering was formed in stages by Mullen Group acquiring Northern Underwater Systems (N.U.S.) Ltd. in 2004 and combining it in 2006 with the then newly acquired Canadian Dewatering Ltd. Canadian Dewatering provides fluid management services to the energy, mining, construction, pipeline, utility and petro-chemical industries along with infrastructure, environmental and emergency response services to municipalities in western Canada.
In addition to their fleet of portable engineered barges and portable dredges, Canadian Dewatering also operates its commercial diving operations across western Canada through its Northern Underwater Systems division.

Business units in the Drilling and Drilling-Related Services category service the upstream market, which refers to oil and natural gas exploration, drilling and well completions. As such, these business units are highly reliant upon the levels of drilling activity and capital expenditures made by exploration and production companies. The direct services provided include the warehousing, transportation, handling and storage of oilfield fluids, drilling mud and tubulars, rig relocation services and general oilfield hauling. Mullen Group currently has six business units that provide services in this area.

Mullen Oilfield Services L.P. (“Mullen Oilfield“) was part of Mullen Group’s founding operations. It has expanded through the purchase of equipment, terminals and companies since first commencing operations. Mullen Oilfield is proud of its 155 employees who work hard to provide a variety of specialized oilfield transportation services to companies drilling for oil and natural gas in western Canada, most notably rig moving. This involves the dismantling, hauling and rigging up of drilling rigs in challenging, difficult, mountainous terrain and extreme weather conditions.
In 2020, the services of Mullen Oilfield were expanded to include the transportation, handling, storage and computerized inventory management of OCTG for the oil and natural gas industry as well as general oilfield hauling.

Mullen Group’s U.S. & International Logistics segment
Rounding off our Mullen Group overview, we turn to the company’s fourth and smallest segment, U.S. & International Logistics, which offers a robust set of third-party logistics (3PL) services to over 2,700 customers in Canada, the United States and Mexico through a combination of professional representatives and a network of independently owned and managed Station Agents (274 personnel in total), utilizing over 6,000 certified sub-contractor carriers.

HAUListic, the segment’s sole business unit acquired in 2021, houses a proprietary integrated transportation management platform, branded as SilverExpressTM. Notable features of SilverExpressTM include real-time information delivery to customers and carriers, price and capacity discovery, as well as tracking and tracing capabilities. SilverExpress’TM value-added services have driven substantial financial growth, with revenue increasing from C$118.2 million in 2021 to C$184.5 million year-over-year as of Q4 2024. This growth represents approximately 9 percent of total company revenue, an average annual operating margin of 2 percent and an operating margin as a percentage of net revenue of 17.1 percent over the period.
The U.S. & International Logistics segment continues to lay the groundwork for long-term growth, diversifying away from Mullen’s core asset-based operations to non-asset, technology-driven revenue. The segment’s low-cost structure is expected to enhance company-wide operating margins as it scales into the billion-dollar 3PL market, which is projected to grow at an estimated 9.2 percent compound annual growth rate (CAGR) through 2030.
Mullen Group’s proven acquisition strategy has long-term potential
Mullen Group’s proven acquisition strategy offers significant long-term growth potential. Our three-part overview reveals a company engaged in essential industries such as transportation, logistics, mining and energy, with a long history of acquiring companies in the transportation and logistics industries and one of the largest portfolios of logistics companies in North America. Over the past 70 years, the company has distinguished itself as an astute capital allocator, prioritizing value for employees and stakeholders alike.
Since becoming a public company in 1993, Mullen has completed just shy of 95 acquisitions, each selected for its people-focused management and potential for long-term, value-accretive growth. The company’s ability to identify untapped market share has resulted in an over 11 percent revenue CAGR since 1993, supported by consistent free cash flow, over C$650 million in high-quality real estate (historical cost), and a steadfast focus on margin expansion through process improvements and tuck-in acquisitions. This strategy continually fortifies the company’s resilience, irrespective of economic cycles.
With over C$126.3 million in cash and C$525 million in borrowing capacity, Mullen is well-positioned to capitalize on acquisition opportunities that meet its precision-based acquisition strategy of the right fit, right price and right synergies. A declining interest rate environment may also enhance consumer and business sentiment, further supporting Mullen’s profitable growth trajectory. This momentum is likely to drive a revaluation of the company’s share price, underscored by its established role in the essential flow of goods that underpin daily life.
