USD Partners LP Announces First Quarter 2019 Results

Houston, TX - USD Partners LP (NYSE: USDP) (the “Partnership”) announced today its operating and financial results for the three months ended March 31, 2019. Financial highlights with respect to the first quarter of 2019 include the following:

• Generated Net Cash Provided by Operating Activities of $10.2 million, Adjusted EBITDA⁽¹⁾ of $11.5 million and Distributable Cash Flow of $8.4million

• Reported Net Income of $1.3 million

• Increased quarterly cash distribution to $0.3625 per unit ($1.45 per unit on an annualized basis), delivering distribution growth of 0.7% over the prior quarter and 2.8% over the first quarter of 2018

• Ended quarter with $181 million of available liquidity

“We are pleased to announce our sixteenth consecutive quarterly distribution increase, which is consistent with our previously stated 2019 distribution guidance,” said Dan Borgen, the Partnership’s Chief Executive Officer. “As we mentioned on our fourth quarter earnings call, we look forward to transitioning into the second half of this year, when the higher rates from our recently extended terminalling services agreements will begin to show up in our financial results. In addition, the forward curves today show the spread between a Western Canadian Select and a West Texas Intermediate barrel of crude oil widening to levels that should incentivize our customers to fully utilize the capacity at our terminals.”

First Quarter 2019 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 results during the first quarter of 2019 relative to the same quarter in 2018 were primarily influenced by lower revenues at its Casper terminal resulting from the conclusion of a customer agreement at the end of 2018, which were partially offset by higher revenues at its Stroud terminal associated with additional contracts that were executed in March and April of 2018. Additionally, the Partnership experienced higher variable operating costs at its Hardisty and Stroud terminals, which it incurred with the anticipation of higher volumes during the quarter, as well as higher operations and maintenance costs at its Stroud terminal, which were partially offset by a reduction in pipeline fees and a decrease in depreciation expense.

Net Cash Provided by Operating Activities increased by 26% relative to the first quarter of 2018, primarily due to the timing of receipts and payments on accounts receivable, accounts payable and deferred revenue balances.

Adjusted EBITDA decreased by 15% and Distributable Cash Flow (“DCF”) decreased by 24% relative to the first quarter of 2018. The decrease in Adjusted EBITDA was primarily a result of the operating factors

⁽¹⁾The Partnership presents both GAAP and non-GAAP financial measures in this press release to assist in understanding the Partnership’s liquidity and ability to fund distributions. See “Non-GAAP Financial Measures” on page 3 and reconciliations of Net Cash Provided by Operating Activities, the most directly comparable GAAP measure, to Adjusted EBITDA and Distributable Cash Flow on page 8 of this press release.

discussed above. DCF was also impacted by higher cash paid for interest associated with higher interest rates in the first quarter of 2019.

Net income for the quarter decreased as compared to the first quarter of 2018, primarily as a result of the operating factors discussed above coupled with a non-cash loss associated with the five-year interest rate derivative instrument that the Partnership entered into in November 2017 and higher interest expense incurred resulting from higher interest rates during the first quarter of 2019.

As of March 31, 2019, the Partnership had total available liquidity of $181 million, including $3 million of unrestricted cash and cash equivalents and undrawn borrowing capacity of $177 million on its $385 million senior secured credit facility, subject to continued compliance with financial covenants. The Partnership is in compliance with its financial covenants.

On April 26, 2019, the Partnership declared a quarterly cash distribution of $0.3625 per unit ($1.45 per unit on an annualized basis), which represents growth of 0.7% over the prior quarter and 2.8% over the first quarter of 2018. The distribution is payable on May 15, 2019, to unitholders of record at the close of business on May 7, 2019.

Effective January 1, 2019, the Partnership adopted the requirements of Accounting Standards Update 2016-02, or ASC 842, that requires balance sheet recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases.

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 on page 8 of this press release.
