BETHESDA, Md.–(BUSINESS WIRE)–In a special letter to investors (see below), John Keppler, Chairman and
Chief Executive Officer of Enviva Partners, LP (NYSE:EVA) (the
“Partnership” or “we”), today provided an update on the operational and
financial implications of the recent fire at the Partnership’s marine
export terminal in the Port of Chesapeake, Virginia.

“Thanks to the extraordinary work of the Enviva team onsite at our
Chesapeake terminal following the February 27^th fire, we
currently expect the terminal to return to full operation by June 30,
2018,” said Keppler. “Moreover, given the flexibility that our portfolio
of multiple plants and ports provides, we have met and expect to
continue meeting every customer delivery required this year under our
off-take agreements. Importantly, as we believe substantially all the
costs of the incident are recoverable, we are reaffirming full-year 2018
per unit distribution guidance of at least $2.53, with continued
quarter-over-quarter increases expected throughout the year.”

Additionally, although the Partnership’s full-year adjusted EBITDA and
distributable cash flow guidance provided in its February 22, 2018
earnings release remains achievable, the actual amounts we report for
any specific quarter and for full-year 2018 will be partially dependent
on the amount of recoveries from insurers and other responsible parties,
the timing and performance of which are not entirely within the
Partnership’s control. In addition, quarterly distribution coverage
ratios may not be comparable to the Partnership’s previously reported
periods or targets, as incident costs and recoveries may not fall within
the same periods.

Special Letter to Investors Follows Below

Dear Enviva Partners, LP Investors,

Just over a month ago, we reported that a fire occurred at Enviva’s
deep-water export terminal in Chesapeake, Virginia. Most importantly, no
one was injured and the fire was quickly controlled due to the efforts
of onsite personnel and the Chesapeake terminal’s fire suppression and
mitigation processes, with assistance from local fire departments and
other first responders. I am pleased to report that the site continues
to be safety incident free since that time and our neighbors in the
community do not appear to have been impacted.

We are now underway with restoring the terminal to full operation and
wanted to provide an update on our progress and further details on the
event and its implications.

Update on Fire Incident

The fire was extinguished shortly after it began on February 27, 2018.
Based on preliminary investigations, we believe it started in equipment
near the top of one of the concrete storage domes and then spread to
inventory in the domes. We deployed a purpose-built nitrogen fire
suppression system in the domes to disperse liquid nitrogen, which
limited the combustibility of the inventory.

Over the past several weeks, our onsite personnel, in concert with
experts we retained, slowly discharged product from the domes. During
that process, we encountered residual hot spots in the inventory, which
made it necessary to deluge the discharged product with water to reduce
the risk of combustion as the inventory came in contact with oxygen in
the external air upon exiting the domes. Consequently, the approximately
43,000 tons of inventory onsite at the time of the fire were a total
loss. The process of emptying the domes is now complete.

Based on our current assessments, which are ongoing, we believe the most
significant physical damage to the terminal assets is limited to the
conveyors and handling equipment required for loading and storing the
product in the domes. Neither the truck receiving assets upstream of the
domes, nor the conveyors and shiploader downstream of the domes, appear
to have been affected. The structural integrity of the domes also
appears not to have been impacted.

Every Customer Delivery Being Met; Terminal Expected to Return to
Operation by June 30

^th

Shortly after the incident, our operations and logistics teams
commissioned temporary storage and shiploading operations at a nearby
terminal in Norfolk, Virginia. Production from our wood pellet
production plants in the mid-Atlantic region is now being delivered to
this Norfolk terminal, as well as to our terminal in the Port of
Wilmington, North Carolina. We loaded our first vessel in Norfolk on
March 18, using reception, storage, and shiploading infrastructure that
did not exist there only a few weeks earlier. Several ships have been
loaded and sailed from Norfolk since that time, and the robust
capabilities of our Wilmington terminal have filled the gap with
uninterrupted shipping at higher than normal volumes due to the
incremental pellets from the mid-Atlantic production plants.

Although we are incurring incremental costs from the extended logistics
chain of longer truck hauls and temporary terminaling and storage
facilities, we believe that the current arrangements provide a durable
solution as we work to bring the Chesapeake terminal back into safe
operation. We expect the Chesapeake terminal to return to full operation
by June 30, 2018.

The flexibility and risk mitigation provided by our portfolio of plants
and ports have enabled us to meet every customer delivery required under
our off-take agreements since the incident. Our plants are running and
our ports are shipping at rates that we believe position us to meet all
of our contractual requirements for the balance of the year, although
specific timing of shipments may be affected from one quarter to the
next.

Substantially All Costs of Incident Should be Recoverable

Turning to the financial impact of the incident, we do not believe the
underlying profitability or cost position of our business will be
affected once the Chesapeake terminal returns to full operation. The
events that took place in Chesapeake are financial and operational risks
we identified as part of our industrial risk management process, and we
believe substantially all of the costs resulting from the incident are
recoverable through our insurance or other contractual rights.

We expect we will bear the immediate costs of the event, including
emergency response costs, inventory and asset write-offs, and inventory
disposal, in the first quarter of 2018. Specifically, the value of the
lost inventory, inclusive of disposal costs, and emergency response
costs are expected to be in the range of $10 million to $12 million and
$8 million to $10 million, respectively. We expect the cost to repair
damage to the terminal to be between $4 million and $8 million. Our
insurance group has been collaborative and responsive—we already have
received substantial advance payments from them—and, despite the
incremental cash costs borne by us prior to receipt of insurance
proceeds or other recoveries, we remained undrawn on our $100 million
revolver at the end of the first quarter. We anticipate that these
event-related costs, which are included in our financial results as a
reduction of net income, will be added back in our calculation of
adjusted EBITDA.

Business continuity costs, however, are expected to reduce adjusted
EBITDA in both the first and second quarters. The incremental costs of
our extended logistics chain are expected to be approximately $4 million
per month through June 30, when we expect the terminal to return to full
service. We also expect substantially all of these operational costs to
be recoverable under our insurance policies, but the timing of the
incurrence of the costs and their recovery will not match. Given this
potential timing mismatch, our reported adjusted EBITDA will include
variability between quarters that does not reflect the underlying
ratable performance of the business and our quarterly distribution
coverage ratios may not be comparable to those for previously reported
periods or our targets for the full year.

Reaffirming 2018 Guidance for Cash Distributions of at Least $2.53
Per Common and Subordinated Unit, With Quarter-Over-Quarter Increases
Expected

The full-year 2018 adjusted EBITDA and distributable cash flow we guided
to in our earnings release on February 22, 2018 remain achievable, but,
as noted above, are partially dependent upon the amount of recoveries
from our insurers and other responsible parties, the timing and
performance of which are not entirely within our control and which may
straddle quarters and possibly extend into 2019.

With our confidence in the underlying long-term stability of the
business and our expectation of the recoverable nature of the costs of
the Chesapeake incident, we are reaffirming our guidance for
distributions of at least $2.53 per common and subordinated unit for
full-year 2018, with quarter over quarter increases expected throughout
the year.

Long-Term Growth Plans of Our Business Remain Intact

It is worth noting that, notwithstanding the impacts of the fire, we
believe our response demonstrates the effectiveness of our business and
operational model. That model, which was designed to mitigate the
potential impact of an event such as this, appears to have worked to
protect our people, assets, customer commitments, and distributions to
our unitholders.

With expected recoveries from our insurers and responsible parties, our
financial results for the full year should not be materially affected
and our plans for the long-term growth of our business remain intact.

We are a company, however, that values continuous improvement and
discipline in our thinking. We will learn from this event, and we will
use these learnings to further extend our industry-leading position.

I am looking forward to sharing our continued progress with you on our
forthcoming earnings call for the first quarter in early May. In the
meantime, thank you for your continued confidence in our Company.

Best regards,
John Keppler
Chairman and Chief Executive Officer
