Clean Harbors Signs Definitive Agreement to Acquire Veolia North America’s Industrial Cleaning Services Division

$120 Million Transaction Will Broaden Clean Harbors’ Industrial
Service Capabilities, Geographic Reach and Customer Base

NORWELL, Mass.–(BUSINESS WIRE)–Clean
Harbors, Inc. (“Clean Harbors”) (NYSE: CLH) and Veolia Environmental
Services North America, LLC, a subsidiary of Veolia North America, Inc.
(“Veolia”), today announced the signing of a definitive agreement
whereby Clean Harbors will acquire Veolia North America’s U.S.
Industrial Cleaning Services Division for $120 million in an all-cash
transaction. The acquisition is expected to close in the first quarter
of 2018, subject to approval by U.S. regulators and other customary
closing conditions.

For the 12 months ended December 31, 2017, Veolia North America’s
Industrial Cleaning Services Division is expected to have revenues of
approximately $210 million. Clean Harbors expects the division to
generate Adjusted EBITDA of approximately $15 million to $20 million in
its first full year of operations, post synergies.

The transaction will enable Clean Harbors to:

• Add significant size, scale and capabilities to its existing U.S.
  Industrial Services business
• Expand its geographic reach, particularly in the Midwest
• Acquire a talented team of employees, including experienced equipment
  operators and managers
• Maximize cross-selling opportunities with its other lines of business
• Leverage operating efficiencies to reduce cost and improve customer
  service
• Accelerate growth in an industry that is recovering from the energy
  downturn

“We are excited about the potential benefits to our customers,
shareholders and industrial services employees from this transaction,”
said Alan S. McKim, Chairman and Chief Executive Officer of Clean
Harbors. “The addition of Veolia’s U.S. Industrial Cleaning Services
Division to our business will enable us to more rapidly grow our
presence in the specialty industrial services market. Its operational
footprint, which complements our North American network, will provide us
with greater scale and density in key U.S. regions such as the Gulf
Coast and will open new industrial markets within the Midwest. This
acquisition also further diversifies our base of blue-chip customers,
many of whom have long-standing relationships with Veolia. In addition,
we expect this acquisition will drive more waste volumes into our
disposal network of incinerators, landfills and other waste treatment
facilities.”

The Veolia division has a fleet of equipment and vehicles consisting of
more than 600 units, including vacuum trucks, roll-off trucks, water
blasters and light duty vehicles. These assets complement a Clean
Harbors’ fleet that today consists of nearly 10,000 pieces of rolling
stock. In addition, Veolia is a leader in providing innovative
technology in the industrial cleaning market, including Hands Free™
technologies and other automated equipment that improve employee safety.

“Like Clean Harbors, Veolia North America makes safety a fundamental
part of its corporate culture and consistently delivers industry-leading
safety results,” McKim said. “It is that commitment to safety, along
with an emphasis on delivering quality service, which we expect will
create a strong cultural fit between our two organizations.”

With more than 60 operating locations across the United States, many of
which are nested inside customer facilities, Veolia’s Industrial
Cleaning Services Division provides a broad range of services to an
extensive customer base. The Division has approximately 1,400 employees
and operates a sizeable service fleet of specialized vehicles and
equipment. Services offered include industrial vacuuming,
hydro-blasting, tank cleaning, chemical cleaning, total waste management
programs, decontamination services and transportation services.

William “Bill” DiCroce, President and CEO of Veolia North America, said,
“Clean Harbors is an ideal acquirer for our U.S. Industrial Cleaning
Services Division. In divesting this business, we sought a partner that
would provide a seamless transition and great continuity for our
customers and our employees in that business.”

“All of our businesses across North America – water, energy, waste and
regeneration – are poised for growth,” added DiCroce. “The proceeds of
this sale will help fuel and accelerate that growth.”

McKim concluded, “We look forward to welcoming the Industrial Cleaning
Services employees to the Clean Harbors family. While the energy markets
have struggled in recent years, we believe they are beginning to
recover. We see this as a compelling acquisition that enables us to
leverage our scale to offer customers a broader selection of industrial
services from a larger network of locations. We also see the opportunity
to drive long-term value for shareholders through the growth prospects
we believe will be created by this transaction.”
