Steel Nation Celebrates 10 Year Anniversary June 8, 2018

Washington, PA – As a full-service construction, engineering, and environmental firm specializing in
pre-engineered metal buildings (PEMBs), Steel Nation Holdings, Inc., along with its affiliated
companies, Steel Nation Buildings, Inc., Steel Nation Engineering, Inc., and Steel Nation
Environmental, Inc., celebrates a decade of providing an array of professional services to clients
primarily in the Oil & Gas industry throughout the Marcellus and Utica Shale plays and beyond. The
ten-year milestone is significant achievement for an organization that began in 2008 as a 1-person
operation and is today, one of the fastest-growing companies in the industry.

“I was very optimistic when I launched Steel Nation in 2008,” said President, Mark D. Caskey, “but I
couldn’t have imagined how quickly the company would grow. I’ve always said that this is a
performance, people, and relationship industry. I credit the success of the company to our
hardworking team and to an expanding list of incredible clients. We are very fortunate.”

When Steel Nation first opened its doors on June 8, 2008, its core business was pre-engineered
metal buildings (PEMBs) for the mining industry. Today, not only has Steel Nation’s PEMB business
expanded, the company now offers top notch Engineering and Environmental services to the
energy, water/wastewater, healthcare, commercial and heavy industrial sectors.

Mark Dooley, EVP/ CFO said, “We’ve hand-picked our team of experts who help us remain focused
on not only keeping pace with emerging customer markets but also anticipating their future needs.
Steel Nation Environmental and Engineering divisions are discovering exciting opportunities in
business sectors that were barely on our radar five years ago.”

“Although we’re very proud of our accomplishments,” said Alan Reid, EVP, “we recognize that to
continue on our path to success means that we need to drive further innovation and we need to be
even more responsive to the needs of our business partners. I have no doubt that we’ll succeed.”

In celebration of the 10 Year Anniversary, Steel Nation will host clients, vendors, and employees at a
private business event on Friday June 8, 2018.
