Exterran Corporation Announces Impact from Hurricane Harvey

Third Quarter 2017 Oil and Gas Product Sales Revenue and Gross Margin
Lowered Due to Factory Downtime

HOUSTON–(BUSINESS WIRE)–Exterran Corporation (NYSE: EXTN) (“Exterran” or the “Company”) today
announced the impact of Hurricane Harvey on the Company’s operations.

No material damage was reported to the Company’s two Houston-area
manufacturing facilities. Both facilities have returned to full
operations. However, both locations were closed for more than a week due
to the catastrophic flooding in and around the Houston area. As a
result, it is estimated that production downtime will result in up to
$20 million of revenue and up to $3 million in gross margin shifting
from the third quarter of 2017 to future periods. The delayed revenue
and gross margin will impact the Company’s oil and gas product sales
segment. No material changes to other line items are anticipated.

Andrew Way, Exterran’s President and CEO, said, “Hurricane Harvey was an
unprecedented disaster for Houston and Southeast Texas, impacting all of
our stakeholders. Our thoughts are with our employees and members of the
community who have suffered a loss as a result of the storm. At the same
time, we would like to thank our employees who have rallied to support
other employees and the community in general. We had many employees who
joined in life-saving activities during the storm and many more involved
in post-storm recovery and humanitarian efforts. Our Houston facilities
are back to full production and we are working hard to make up the lost
production to meet our customers’ needs.”
