SHELL MIDSTREAM PARTNERS, L.P. 1st QUARTER 2022 UNAUDITED RESULTS

Shell Midstream Partners, L.P. (NYSE: SHLX) (the “Partnership” or “Shell Midstream Partners”) reported net income attributable to the Partnership of $158 million for the first quarter of 2022, which equated to $0.36 per diluted common limited partner unit. Shell Midstream Partners also generated adjusted earnings before interest, income taxes, depreciation and amortization attributable to the Partnership of $182 million. 

Total cash available for distribution was $157 million, which is $15 million higher than the prior quarter. The increasewas largely driven by increased volumes across our systems, which were impacted by repairs related to Hurricane Ida in the prior quarter. Repairs to the West Delta facility were completed in early November 2021, such that all Partnership assets were operating at normal levels throughout the first quarter.

The Board of Directors of our general partner (the “Board”) previously declared a cash distribution of $0.30 per limited partner common unit for the first quarter of 2022, consistent with the prior quarter, resulting in a coverage ratio for the quarter of 1.3x.  The distribution will be paid May 13, 2022 to unitholders of record as of May 3, 2022. 

FINANCIAL HIGHLIGHTS

• Net income attributable to the Partnership was $158 million, compared to $104 million for the prior quarter.
• Net cash provided by operating activities was $157 million, compared to $123 million for the prior quarter.
• Cash available for distribution was $157 million, compared to $142 million for the prior quarter.
• The board of directors of Colonial elected not to declare a dividend for the three months ended March 31, 2022.
• Total cash distribution declared for common units was $118 million, resulting in a coverage ratio of 1.3x.
• Adjusted EBITDA attributable to the Partnership was $182 million, compared to $167 million for the prior quarter.
• As of March 31, 2022, the Partnership had $251 million of consolidated cash and cash equivalents on hand.
• As of March 31, 2022, the Partnership had total debt of $2.5 billion, equating to 3.5x Debt to annualized Q1 2022 Adjusted EBITDA. Current debt levels are well within our targeted range and provide flexibility to the Partnership.

Adjusted EBITDA and Cash available for distribution are non-GAAP supplemental financial measures. See the reconciliation to their most comparable GAAP measures later in this press release.

ASSET HIGHLIGHTS

Significant Onshore Pipeline Transportation:

• • Zydeco - Mainline volumes were 535 kbpd in the current quarter, compared to 530 kbpd in the prior quarter.

Significant Offshore Pipeline Transportation:

• During the quarter, volumes increased primarily due to completion of repairs related to Hurricane Ida in early November 2021, such that systems were running at normal operating levels throughout the first quarter.
• Mars - Volumes were 488 kbpd, compared to 408 kbpd in the prior quarter.
• Amberjack - Volumes were 340 kbpd, compared to 346 kbpd in the prior quarter.
• Eastern Corridor - Volumes were 393 kbpd, compared to 425 kbpd in the prior quarter.

Outlook

• On April 27, 2022, the Administrative Law Judge issued a second partial initial decision related to Colonial’s ongoing rate case with the Federal Energy Regulatory Commission addressing the issues not covered in the first partial initial decision issued on December 1, 2021. Colonial has begun to review the decision.
• Based on current producer schedules, we expect an impact of approximately $15 million to both net income and cash available for distribution in 2022 related to certain planned producer turnarounds.
• On February 11, 2022, the Board received a non-binding, preliminary proposal letter from SPLC to acquire all of the Partnership’s issued and outstanding common units not already owned by SPLC or its affiliates at a value of $12.89 per each issued and outstanding publicly-held common unit (the “Proposal”). The Board has appointed the conflicts committee to review, evaluate and negotiate the Proposal.
• As of March 31, 2022, the Partnership has approximately $1.3 billion in available liquidity, which is a combination of cash and cash equivalents and availability under credit facilities.

NON-GAAP FINANCIAL MEASURES

This press release includes the terms Adjusted EBITDA and cash available for distribution. We believe that the presentation ofAdjusted EBITDA and cash available for distribution provides useful information to investors in assessing our financialcondition and results of operations. Adjusted EBITDA and cash available for distribution are non-GAAP supplementalfinancial measures that management and external users of our consolidated financial statements, such as industry analysts,investors, lenders and rating agencies, may use to assess:

• our operating performance as compared to other publicly traded partnerships in the midstream energy industry,without regard to historical cost basis or, in the case of Adjusted EBITDA, financing methods;• the ability of our business to generate sufficient cash to support our decision to make distributions to ourunitholders;• our ability to incur and service debt and fund capital expenditures; and• the viability of acquisitions and other capital expenditure projects and the returns on investment of variousinvestment opportunities.

The GAAP measures most directly comparable to Adjusted EBITDA and cash available for distribution are net income and netcash provided by operating activities. These non-GAAP measures should not be considered as alternatives to GAAP net incomeor net cash provided by operating activities. Adjusted EBITDA and cash available for distribution have important limitations asanalytical tools because they exclude some but not all items that affect net income and net cash provided by operating activities.They should not be considered in isolation or as substitutes for analysis of our results as reported under GAAP. Additionally,because Adjusted EBITDA and cash available for distribution may be defined differently by other companies in our industry,our definition of Adjusted EBITDA and cash available for distribution may not be comparable to similarly titled measures ofother companies, thereby diminishing their utility.

References in this press release to Adjusted EBITDA refer to net income before income taxes, interest expense, interest income,gain or loss from disposition of fixed assets, allowance oil reduction to net realizable value, loss from revision of assetretirement obligations, and depreciation, amortization and accretion, plus cash distributed to Shell Midstream Partners, L.P.from equity method investments for the applicable period, less equity method distributions included in other income and incomefrom equity method investments. We define Adjusted EBITDA attributable to Shell Midstream Partners, L.P. as AdjustedEBITDA less Adjusted EBITDA attributable to noncontrolling interests and Adjusted EBITDA attributable to Shell plc and itscontrolled affiliates, other than us, our subsidiaries and our general partner (collectively, “Parent”). References to cashavailable for distribution refer to Adjusted EBITDA attributable to Shell Midstream Partners, L.P., less maintenance capitalexpenditures attributable to Shell Midstream Partners, L.P., net interest paid by the Partnership, cash reserves, income taxespaid and Series A Preferred Units distributions, plus net adjustments from volume deficiency payments attributable to ShellMidstream Partners, L.P., reimbursements from Parent included in partners’ capital, principal and interest payments receivedon financing receivables and certain one-time payments received. Cash available for distribution will not reflect changes inworking capital balances. We define maintenance capital expenditures as cash expenditures, including expenditures for (a) theacquisition (through an asset acquisition, merger, stock acquisition, equity acquisition or other form of investment) by thePartnership or any of its subsidiaries of existing assets or assets under construction, (b) the construction or development of newcapital assets by the Partnership or any of its subsidiaries, (c) the replacement, improvement or expansion of existing capitalassets by the Partnership or any of its subsidiaries or (d) a capital contribution by the Partnership or any of its subsidiaries toa person that is not a subsidiary in which the Partnership or any of its subsidiaries has, or after such capital contribution willhave, directly or indirectly, an equity interest, to fund the Partnership or such subsidiary’s share of the cost of the acquisition,construction or development of new, or the replacement, improvement or expansion of existing, capital assets by such person,in each case if and to the extent such acquisition, construction, development, replacement, improvement or expansion is madeto maintain, over the long-term, the operating capacity or operating income of the Partnership and its subsidiaries, in the caseof clauses (a), (b) and (c), or such person, in the case of clause (d), as the operating capacity or operating income of thePartnership and its subsidiaries or such person, as the case may be, existed immediately prior to such acquisition, construction,development, replacement, improvement, expansion or capital contribution. For purposes of this definition, “long-term”generally refers to a period of not less than twelve months.
