Diversey, a global leader in the hygiene and cleaning industry, today
announced that Mark S. Burgess is resigning as Chief Executive Officer
effective January 9, 2020 to take another executive role, and will be
replaced on an interim basis by Philip R. Wieland who most recently
served as the Company’s Chief Financial Officer. Burgess will remain on
the Board of Directors and work closely with Wieland to ensure a smooth
executive transition. Diversey has launched an external search for a new

Wieland has deep experience as a senior executive of scale services
organizations, having served as CEO of UK and Ireland operations and as
Group CFO of Brakes, a leading European food service business with
revenues of 4 billion Euros and 13,000 employees. He was previously CFO
of General Healthcare Group, a private owner of hospitals in the UK, and
served in a number of executive roles at British Sky Broadcasting. He
received a Bachelor’s degree from the University of Leeds.

Wieland is succeeded in the CFO role by Todd Herndon, an experienced
financial management executive who is returning to the Company after
holding a series of positions of increasing responsibility over eight
years at Diversey Care, including general manager of the Building Care
core business, and Vice President of Finance at the time of its
acquisition by Sealed Air Corporation (NYSE: SEE). He has since held the
CFO role at Gardner Denver (NYSE: GDI), a leading global provider of
industrial technology and services where he helped lead the company’s
successful 2017 initial public offering. Herndon also served as CFO at
Capital Safety, a maker of protective equipment where he oversaw the
company’s $2.5 billion acquisition by 3M Company (NYSE: MMM) in 2015. He
earned a Bachelor’s degree at Indiana University, and an MBA from
Marquette University.

“Diversey has made great strides in growing in our key target markets,
and becoming a stronger and more profitable and sustainable company,”
said Burgess. “Organizing the business around more regionally-focused
leadership has allowed us to get much closer to our customers and
service them more effectively. I am honored to have had the opportunity
to lead the Company alongside a talented executive team and in
partnership with our associates around the world. I know this team will
continue to perform, driving solid growth and continuing to deliver
value for our customers and partners.”

“I am excited to lead the business as we build upon the positive
momentum created by the strategic, operational and financial
accomplishments of the Diversey team over the past year, including three
percent year-over-year constant currency revenue growth and over 20
percent EBITDA growth in the third quarter that we expect to continue in
the fourth quarter,” added Wieland. “I look forward to working closely
with Todd and the leadership team in executing our growth plans. We
believe this momentum positions Diversey for continued success in 2020
and beyond as we remain focused on growing in our key markets while
serving the needs of our customers with better solutions and products
that will help them win in the marketplace.”

Diversey made several strategic moves in 2019 to expand its
differentiated platform. In December, it announced the acquisition of
the global intellectual property rights related to Accelerated Hydrogen
Peroxide® (AHP), an innovative and revolutionary technology, from Virox
Technologies, Inc. Previously, Diversey announced a significant
investment in a new R&D center in China, a key milestone in the
execution of the Company’s Asia strategy. The Company also made
additional investment to support its continued growth in the U.S.
market where development has begun on a new North American R&D
laboratory in Fort Mill, SC, and where Diversey has added over
20,000 Food Service locations in the past 18 months.

“Thanks to the hard work and leadership of Mark and the management team,
Diversey is well-positioned to seize the many opportunities that lie
ahead, and we are grateful we will benefit from his continued presence
on the Board,” said Ken Hanau, Chairman of the Diversey Board of
Directors and a Managing Director at Bain Capital. “We are pleased with
the significant progress Diversey has made since becoming a standalone
company in 2017 and look forward to working with Phil and Todd as we
continue to drive growth both organically and through acquisitions.”
