HOUSTON–(BUSINESS WIRE)–Solaris Oilfield Infrastructure, Inc. (NYSE:SOI) today announced it
recently acquired the assets of Railtronix, LLC (www.railtronix.com),
a leading provider of real-time inventory management solutions for
proppant mining, rail shipping and transloading operations. Railtronix
is based in Houston and provides mission critical data to some of the
most active proppant suppliers and oilfield service companies across the
U.S. Concurrent with the closing of the transaction, Railtronix’s
founder and Chief Executive Officer Alfonso Olvera has joined Solaris as
Senior Vice President of Technology.

Solaris’ Chief Executive Officer Greg Lanham commented, “By combining
Railtronix’s inventory data upstream of the well site with Solaris’ well
site logistics and inventory monitoring capabilities, we are uniquely
positioned to deliver a comprehensive and dynamic picture of inventory
across the supply chain to our customers. Solaris is focused on
continuing to innovate and create solutions to help our customers
improve well level economics – Railtronix is a natural fit with this
strategy as we work to help prevent costly delays and inventory
shortfalls.”

As the U.S. oil and gas industry continues to transition towards
manufacturing-style development of resource plays, operators and service
companies are looking for new ways to digitalize their supply chains. By
integrating Railtronix and PropView™, Solaris is now uniquely positioned
to provide the data to help its customers create and monitor key
performance indicators to improve the reliability of proppant supply,
save time and reduce the delivered cost of proppant.

Concurrent with the transaction, Solaris has created a new, wholly-owned
subsidiary, Solaris Oilfield Technologies, LLC, which will integrate the
two platforms, as well as continue to develop additional offerings to
enhance visibility across the proppant supply chain.

“We are very pleased to have Alfonso on board,” Lanham continued. “He
has built a compelling business with a strong customer base and shares
our entrepreneurial and innovative culture. As we evaluated inventory
monitoring and tracking options for our new Kingfisher transload
facility, we determined that Railtronix offers the greatest insight into
the supply chain and is a logical extension of Solaris’ strategy.”

Alfonso Olvera commented, “I am excited to be joining the Solaris team.
We have both created unique offerings to improve the proppant supply
chain. I believe by combining our efforts, we can accelerate the
adoption of both the Railtronix offering and Solaris’ well site proppant
management systems and PropView™. This combination will provide
significant commercial and revenue synergies for the combined offering,
as well as support further innovation.”

Solaris expects the transaction to be accretive to earnings per share in
2018. Solaris funded the acquisition with available cash and through the
issuance of Class B Shares.
