USD Partners LP Announces Third Quarter 2021 Results

Houston, TX - USD Partners LP (NYSE: USDP) (the “Partnership”) announced today its operating and financial results for the three and nine months ended September 30, 2021. Financial highlights with respect to the third quarter of 2021 include the following:

•Generated Net Cash Provided by Operating Activities of $11.0 million, Adjusted EBITDA(1) of $12.3 million and Distributable Cash Flow(1) of $10.7million

•Reported Net Income of $3.8 million

•Amended and extended existing revolving credit agreement, extending the maturity date by one year to November 2, 2023

•Increased quarterly cash distribution to $0.1185 per unit ($0.474 per unit on an annualized basis) with over 3.0x Distributable Cash Flow Coverage(2)

“During the third quarter, we were excited to announce that construction of the Sponsor’s Diluent Recovery Unit, or DRU, and its destination facility at Port Arthur were completed,” said Dan Borgen, the Partnership’s Chief Executive Officer. “Both the DRU and the Port Arthur Terminal are now operating in the start-up phase, and throughput volumes are consistent with contractual obligations and our customer’s expectations. As mentioned previously, our DRUbit™ by Rail™ network has already enhanced the sustainability and quality of the Partnership’s cash flows by significantly increasing the tenor of three terminalling services agreements at the Partnership’s Hardisty terminal, representing approximately 32% of the terminal’s capacity, through 2031. In addition, our DRUbit™ by Rail™ network provides transportation safety and environmental benefits to our customers, as well as increased market access and additional jobs along the rail routes.”

“We continue to be very excited about our future as we engage with our customers regarding the second phase of USD’s growth, which could include a second DRU customer commitment, with the resulting DRUbitTM available to be transloaded through the Partnership’s Hardisty rail terminal to the Gulf Coast and other potential destinations,” added Mr. Borgen. “We look forward to keeping our investors updated with future announcements regarding the DRU.”

“The Partnership also announced it has successfully amended and extended its senior secured credit facility for an additional year,” said Adam Altsuler, the Partnership’s Chief Financial Officer. “The success of the extension was largely due to our supportive bank group, our strong contracted cash flows and conservative leverage position, and the positive market outlook for our strategically located assets.”

Partnership’s Third Quarter 2021 Liquidity, Operational and Financial Results

Substantially all of the Partnership’s cash flows are generated from multi-year, take-or-pay terminalling services agreements related to its crude oil terminals, which include minimum monthly commitment fees. The Partnership’s customers include major integrated oil companies, refiners and marketers, the majority of which are investment-grade rated.

The Partnership’s operating results for the third quarter of 2021 relative to the same quarter in 2020 were primarily influenced by lower revenue at the Stroud terminal during the quarter associated with the existing DRU customer electing to reduce its contracted volume commitments by one-third of their previous commitment effective August 2021, which was primarily driven by the successful commencement of the DRU. These factors were partially offset by slightly higher revenue at the Hardisty terminal in the third quarter of 2021 relative to the third quarter of 2020 due to a favorable variance resulting from the change in the Canadian exchange rate associated with the Partnership’s Canadian-dollar denominated contracts.

The Partnership experienced higher operating costs during the third quarter of 2021 as compared to the third quarter of 2020 primarily attributable to an increase in subcontracted rail services costs due to increased throughput.

Net income decreased in the third quarter of 2021 as compared to the third quarter of 2020, primarily because of the operating factors discussed above coupled with a non-cash foreign currency transaction loss in the third quarter of 2021 as compared to a non-cash gain recognized in the 2020 comparative period. Partially offsetting was lower interest expense incurred during the 2021 period resulting from lower interest rates and a lower weighted average balance of debt outstanding and a small non-cash gain associated with the Partnership’s interest rate derivatives during the third quarter of 2021 as compared to a non-cash loss during the same period in 2020.

Net Cash Provided by Operating Activities for the quarter decreased 34% relative to the third quarter of 2020, primarily due to the operating factors discussed above and the general timing of receipts and payments of accounts receivable, accounts payable and deferred revenue balances.

Adjusted EBITDA and Distributable Cash Flow (“DCF”) decreased by 21% and 24%, respectively, for the quarter relative to the third quarter of 2020. The decrease in Adjusted EBITDA was primarily a result of the operating factors discussed above. DCF was also impacted by an increase in cash paid for income taxes and higher maintenance capital expenditures incurred during the current quarter, which included technology upgrades and safety maintenance at the Partnership’s Hardisty and Stroud terminals. Partially offsetting was a decrease in cash paid for interest during the quarter.

As of September 30, 2021, the Partnership had approximately $4.4 million of unrestricted cash and cash equivalents and undrawn borrowing capacity of $211.0 million on its $385.0 million senior secured credit facility, subject to the Partnership’s continued compliance with financial covenants. As of the end of the third quarter of 2021, the Partnership had borrowings of $174.0 million outstanding under the revolving credit facility. The Partnership was in compliance with its financial covenants, as of September 30, 2021.

On October 29, 2021 the Partnership and its subsidiaries entered into an amendment to its senior secured credit facility with its bank group. Among other things, the amendment extends the maturity date by one year to November 2, 2023 and decreases the aggregate revolving commitments of the lenders from $385 million to $275 million. After giving effect to the amendment, the Partnership has the ability to request one additional one-year maturity date extension, subject to the satisfaction of certain conditions, including consent of the lenders. The terms and conditions of the senior secured credit facility, as amended, are substantially similar to the terms and conditions in the senior secured credit facility prior to the amendment, except that the senior secured credit facility, as amended, sets forth provisions for replacing LIBOR with an alternative benchmark rate.

2

Pursuant to the terms of the Partnership’s senior secured credit facility, as amended, the Partnership’s borrowing capacity continues to be limited to 4.5 times its trailing 12-month consolidated EBITDA, as defined in the senior secured credit facility. As such, the Partnership’s available borrowings under the senior secured credit facility, including unrestricted cash and cash equivalents, was approximately $92 million as of September 30, 2021.

On October 21, 2021, the Partnership declared a quarterly cash distribution of $0.1185 per unit ($0.474 per unit on an annualized basis), representing an increase of $0.0025 per unit, or 2.2% over the distribution declared for the second quarter of 2021. The distribution is payable on November 12, 2021, to unitholders of record at the close of business on November 3, 2021.

Since the end of the first quarter of 2020, the Partnership has reduced the outstanding balance of its revolving credit facility by $50 million as of September 30, 2021.

Non-GAAP Financial Measures

The Partnership defines Adjusted EBITDA as Net Cash Provided by Operating Activities adjusted for changes in working capital items, interest, income taxes, foreign currency transaction gains and losses, and other items which do not affect the underlying cash flows produced by the Partnership’s businesses. Adjusted EBITDA is a non-GAAP, supplemental financial measure used by management and external users of the Partnership’s financial statements, such as investors and commercial banks, to assess:

•the Partnership’s liquidity and the ability of the Partnership’s businesses to produce sufficient cash flows to make distributions to the Partnership’s unitholders; and

•the Partnership’s ability to incur and service debt and fund capital expenditures.

The Partnership defines Distributable Cash Flow, or DCF, as Adjusted EBITDA less net cash paid for interest, income taxes and maintenance capital expenditures. DCF does not reflect changes in working capital balances. DCF is a non-GAAP, supplemental financial measure used by management and by external users of the Partnership’s financial statements, such as investors and commercial banks, to assess:

•the amount of cash available for making distributions to the Partnership’s unitholders;

•the excess cash flow being retained for use in enhancing the Partnership’s existing business; and

•the sustainability of the Partnership’s current distribution rate per unit.

The Partnership believes that the presentation of Adjusted EBITDA and DCF in this press release provides information that enhances an investor’s understanding of the Partnership’s ability to generate cash for payment of distributions and other purposes. The GAAP measure most directly comparable to Adjusted EBITDA and DCF is Net Cash Provided by Operating Activities. Adjusted EBITDA and DCF should not be considered alternatives to Net Cash Provided by Operating Activities or any other measure of liquidity presented in accordance with GAAP. Adjusted EBITDA and DCF exclude some, but not all, items that affect Net Cash Provided by Operating Activities and these measures may vary among other companies. As a result, Adjusted EBITDA and DCF may not be comparable to similarly titled measures of other companies. Reconciliations of Net Cash Provided by Operating Activities to Adjusted EBITDA and DCF are presented in this press release.
