1. Description of the Business and Basis of Presentation

Shell Midstream Partners, L.P. (“we,” “us,” “our,” “SHLX” or “the Partnership”) is a Delaware limited partnership formed by Shell plc on March 19, 2014 to own and operate pipeline and other midstream assets, including certain assets purchased from Shell Pipeline Company LP (“SPLC”) and its affiliates.

Our general partner is Shell Midstream Partners GP LLC (“general partner”). References to “Shell” or “Parent” refer collectively to Shell plc and its controlled affiliates, other than us, our subsidiaries and our general partner.

As of ~~March~~June 3130, 2022, our general partner holds a non-economic general partner interest in the Partnership, and affiliates of SPLC own a 68.5% limited partner interest (269,457,304 common units) and 50,782,904 Series A perpetual convertible preferred units (the “Series A Preferred Units”) in the Partnership. These common units and preferred units, on an as-converted basis, represent a 72% interest in the Partnership. See Note 78 – (Deficit) Equity for additional details.

Take Private Proposal

On February 11, 2022, the Board of Directors of our general partner (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. Refer to Note 13 – Subsequent Events – Merger Agreement for additional information.

The proposed transaction is subject to a number of contingencies, including the approval of the Board, the negotiation of a definitive agreement concerning the transaction, and the satisfaction of conditions to the consummation of a transaction set forth in any such definitive agreement.

Basis of Presentation

Our unaudited consolidated financial statements include all subsidiaries required to be consolidated under generally accepted accounting principles in the United States (“GAAP”). Our reporting currency is U.S. dollars, and all references to dollars are U.S. dollars. The accompanying unaudited consolidated financial statements and related notes have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete annual financial statements. The year-end consolidated balance sheet data was derived from audited financial statements. During interim periods, we follow the accounting policies disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021 (our “2021 Annual Report”), filed with the United States Securities and Exchange Commission (“SEC”), unless otherwise described herein. The unaudited consolidated financial statements for both the three and six months ended ~~March~~June 3130, 2022 and ~~March~~June 3130, 2021 include all adjustments we believe are necessary for a fair statement of the results of operations for the interim periods presented. These adjustments are of a normal recurring nature unless otherwise disclosed. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year. These unaudited consolidated financial statements and other information included in this Quarterly Report on Form 10-Q should be read in conjunction with our audited consolidated financial statements and notes thereto included in our 2021 Annual Report.

Our consolidated subsidiaries include Pecten, Sand Dollar, Triton, Zydeco, Odyssey and the Operating Company. Asset acquisitions of additional interests in previously consolidated subsidiaries and interests in equity method and other investments are included in the financial statements prospectively from the effective date of each acquisition. In cases where these types of acquisitions are considered acquisitions of businesses under common control, the financial statements are retrospectively adjusted.

Summary of Significant Accounting Policies

The accounting policies are set forth in Note 2 – Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements of our 2021 Annual Report. There have been no significant changes to these policies during the ~~three~~six months ended ~~March~~June 3130, 2022.

2. ~~Related~~Acquisitions ~~Party~~and Other Transactions

~~Related~~May ~~party~~2021 transactions include transactions with SPLC and Shell, including those entities in which Shell has an ownership interest but does not have control. See Note 1 – Description of the Business and Basis of Presentation – Take Private Proposal for additional information regarding the non-binding, preliminary proposal letter that the Board received from SPLC to acquire all of the Partnership’s issued and outstanding common units not already owned by SPLC or its affiliates.Transaction

Effective May 1, 2021, Triton sold to Equilon Enterprises LLC d/b/a Shell Oil Products US (“SOPUS”), as designee of SPLC, substantially all of the assets associated with its clean products truck rack terminal and facility in Anacortes, Washington (the “Anacortes Assets”). In exchange for the Anacortes Assets, SPLC paid Triton $10 million in cash and transferred to the Operating Company, as designee of Triton, SPLC’s 7.5% interest in Zydeco (the “May 2021 Transaction”). Effective May 1, 2021, the Partnership owned a 100.0% ownership interest in Zydeco.

The May 2021 Transaction closed pursuant to a Sale and Purchase Agreement dated April 28, 2021 between Triton and SPLC, effective May 1, 2021 (the “May 2021 Sale and Purchase Agreement”). The May 2021 Sale and Purchase Agreement contains customary representations, warranties and covenants of Triton and SPLC. SPLC, on the one hand, and Triton, on the other hand, have agreed to indemnify each other and their respective affiliates, officers, directors and other representatives against certain losses resulting from any breach of their representations, warranties or covenants contained in the May 2021 Sale and Purchase Agreement, subject to certain limitations and survival periods.

In connection with the May 2021 Transaction, the Partnership and SPLC entered into a Termination of Voting Agreement dated April 28, 2021 and effective May 1, 2021, under which they agreed to terminate the Voting Agreement dated November 3, 2014 between the Partnership and SPLC, relating to certain governance matters for their respective direct and indirect ownership interests in Zydeco.

Auger Divestiture

In anticipation of the intended divestiture of the 12” segment of the Auger pipeline, we recorded an impairment charge of approximately $3 million during the first quarter of 2021.

Pension and defined contribution benefit plan expenses are included in either General and administrative – related parties or Operations and maintenance – related parties in the accompanying unaudited consolidated statements of income, depending on the nature of the employee’s role in our operations.

Equity and Other Investments

We have equity and other investments in various entities. In some cases, we may be required to make capital contributions or other payments to these entities. See Note 34 – Equity Method Investments for additional details.

Sale Leaseback

Pursuant to the terminaling services agreements entered into among Triton, ~~Equilon Enterprises LLC d/b/a Shell Oil Products US (“~~SOPUS”) and Shell Chemical LP (“Shell Chemical”) related to certain logistics assets at the Shell Norco Manufacturing Complex (the “Norco Assets”), the Partnership receives an annual net payment of $140 million, which is the total annual payment pursuant to the terminaling service agreements of $151 million, less $11 million, which primarily represents the allocated utility costs from SOPUS related to the Norco Assets. The annual payments are subject to annual Consumer Price Index (“CPI”) adjustments. See Note 89 – Revenue Recognition for additional details.

The transfer of the Norco Assets, combined with the terminaling services agreements, were accounted for as a failed sale leaseback under Accounting Standards Codification (“ASC”) Topic 842, Leases (the “lease standard”). As a result, the transaction was treated as a financing arrangement in which the underlying assets were not recognized in property, plant and equipment of the Partnership as control of the Norco Assets did not transfer to the Partnership, and instead were recorded as financing receivables from SOPUS and Shell Chemical.

We recognize interest income on the financing receivables on the basis of an imputed interest rate of 11.1% related to SOPUS and 7.4% related to Shell Chemical. The following table shows the interest income and cash principal payments received on the financing receivables for the three months ended March 31, 2022 and March 31, 2021:

The terminaling services agreements associated with the Norco Assets have operation and maintenance service components and major maintenance service components (together “service components”). Consistent with our operating lease arrangements, we allocate a portion of the arrangement’s transaction price to any service components within the scope of ASC Topic 606, Revenue from Contracts with Customers (“the revenue standard”) and defer the revenue, if necessary, until the point at which the performance obligation is met. We present the revenue earned from the service components under the revenue standard within Transportation, terminaling and storage services – related parties in the unaudited consolidated statements of income. See Note 9 – Revenue Recognition for additional details related to revenue recognized on the service components and amortization of the contract assets.

4. Equity Method Investments

(1) Included in Other is the activity associated with our investments in Permian Basin, LOCAP, Proteus and Endymion.

For the three and six months ended ~~March~~June 3130, 2022, distributions received from equity method investments were $119 million and ~~March~~$230 31million, respectively. For the three and six months ended June 30, 2021, distributions received from equity method investments were $~~111~~ 128 million and $~~123~~ 251 million, respectively.

13Unamortized differences in the basis of the initial investments and our interest in the separate net assets within the financial statements of the investees are amortized into net income over the remaining useful lives of the underlying assets. The amortization is included in Income from equity method investments. As of June 30, 2022 and December 31, 2021, the unamortized basis differences included in our equity investments were $71 million and $75 million, respectively. For both the three and six months ended June 30, 2022 and June 30, 2021, the net amortization expense was $2 million and $4 million, respectively.

Cumulatively, distributions received from Poseidon have been in excess of our investment balance and, therefore, the equity method of accounting has been suspended for this investment and the investment amount reduced to zero. As we have no commitments to provide further financial support to Poseidon, we have recorded excess distributions in Other income of $8 million and $14 million for the three months ended March 31, 2022 and March 31, 2021, respectively. Once our cumulative share of equity earnings becomes greater than the cumulative amount of distributions received, we will resume the equity method of accounting as long as the equity method investment balance remains greater than zero.

Significant Developments

The board of directors of Colonial elected not to declare a dividend for the three months ended ~~March~~June 3130, 2022.

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 (“FERC”) addressing the issues not covered in the first partial initial decision. The Administrative Law Judge did not make a decision on reparations or whether the rates charged by Colonial were just and reasonable. The parties to the case filed briefs on the recommendations in June 2022 and will be filing reply briefs in August 2022. The timing of such ruling is unknown. There is not currently sufficient information to estimate the impact the FERC rate case may have on the Partnership’s financial statements. Depending upon the final outcome of the case, the potential adoption of such decision in whole or in part by the FERC could adversely affect our equity method investment in Colonial, net income and cash available for distribution.

Capital Contributions

We make capital contributions for our pro- rata interest in Permian Basin to fund capital and other expenditures. For the three and six months ended ~~March~~June 3130, 2022, we made no capital contributions, and ~~March~~for the three and six months ended June 3130, 2021, we made capital contributions of ~~zero~~$1 million and ~~approximately~~ $23 million, respectively.

(1) As of both ~~March~~June 3130, 2022 and December 31, 2021, the unamortized debt issuance costs for the current debt payable is less than $1 million and is therefore not being reflected in this table.

Interest and fee expenses associated with our borrowings, net of capitalized interest, were $2021 million and $2141 million, respectively, for the three and six months ended ~~March~~June 3130, 2022. Interest and ~~March~~fee expenses associated with our borrowings, net of capitalized interest, were $20 million and $41 million, respectively, for the three and six months ended June 3130, 2021. We paid $20 million and $40 million for interest, respectively, ofduring ~~which~~the three and six months ended June 30, 2022, and we paid $2017 million and $2441 million for interest, respectively, during the three and six months ended June 30, 2021.

Borrowings and Repayments

Borrowings under the Five Year Revolver due July 2023 and the Five Year Revolver due December 2022 bear interest at the three-month London Interbank Offered Rate (“LIBOR”) plus a margin or, in certain instances (including if LIBOR is discontinued) at an alternate interest rate as described in each respective revolver. LIBOR is being discontinued globally, and as such, a new benchmark will take its place. We are in discussion with our Parent to further clarify the reference rate(s) applicable to our revolving credit facilities once LIBOR is discontinued, and once determined, will assess the financial impact, if any.

Borrowings under these revolving credit facilities approximate fair value as the interest rates are variable and reflective of market rates, which results in Level 2 instruments. The fair value of our fixed rate credit facilities is estimated based on the published market prices for issuances of similar risk and tenor and is categorized as Level 2 within the fair value hierarchy. As of ~~March~~June 3130, 2022, the carrying amount and estimated fair value of total debt (before amortization of issuance costs) was $2,544 million and $2,~~555~~451 million, respectively. As of December 31, 2021, the carrying amount and estimated fair value of total debt (before amortization of issuance costs) was $2,694 million and $2,849 million, respectively.

On February 16, 2022, we used excess cash to repay $150 million of borrowings under the Five Year Revolver due December 2022.

The 2021 Ten Year Fixed Facility was fully drawn on March 23, 2021, and the borrowings were used to repay the borrowings under, and replace, the Five Year Fixed Facility. In consideration for STCW’s consent to the prepayment of the Five Year Fixed Facility, the Partnership incurred a fee of approximately $2 million, which was paid on March 23, 2021. The Five Year Fixed Facility automatically terminated in connection with the prepayment.

Borrowings and repayments under our credit facilities for the ~~three~~six months ended ~~March~~June 3130, 2022 and ~~March~~June 3130, 2021 are disclosed in our unaudited consolidated statements of cash flows. See Note 78 – (Deficit) Equity for additional information regarding the source of our repayments, if applicable to the period.

For additional information on our credit facilities, refer to Note 8 – Related Party Debt in the Notes to Consolidated Financial Statements in our 2021 Annual Report.

7. (Deficit) Equity

General Partner

As of ~~March~~June 3130, 2022, our general partner holds a non-economic general partner interest.

Shelf Registrations

We have a universal shelf registration statement on Form S-3 on file with the SEC under which we, as a well-known seasoned issuer, have the ability to issue and sell an indeterminate amount of common units and partnership securities representing limited partner units.

Units Outstanding

Common units

The common units represent limited partner interests in us. The holders of common units, both public and SPLC, are entitled to participate in partnership distributions and have limited rights of ownership as provided for under the Second Amended and Restated Partnership Agreement.

As of both ~~March~~June 3130, 2022 and December 31, 2021, we had 393,289,537 common units outstanding, of which 123,832,233 were publicly owned. SPLC owned 269,457,304 common units, representing an aggregate 68.5% limited partner interest in us.

Series A Preferred Units

As of both ~~March~~June 3130, 2022 and December 31, 2021, we had 50,782,904 preferred units outstanding. On April 1, 2020, we issued 50,782,904 Series A Preferred Units to SPLC at a price of $23.63 per preferred unit. The Series A Preferred Units rank senior to all common units with respect to distribution rights and rights upon liquidation. The Series A Preferred Units have voting rights, distribution rights and certain redemption rights, and are also convertible (at the option of the Partnership and at the option of the holder, in each case under certain circumstances) and are otherwise subject to the terms and conditions as set forth in the Second Amended and Restated Partnership Agreement. We classified the Series A Preferred Units as permanent equity since they are not redeemable for cash or other assets 1) at a fixed or determinable price on a fixed or determinable date; 2) at the option of the holder; or 3) upon the occurrence of an event that is not solely within the control of the issuer.

Conversion

At the option of Series A Preferred Unitholders. ~~Beginning~~As ~~with the earlier~~ of ~~(1)~~ January 1, 2022 ~~and (2) immediately prior to the liquidation of the Partnership~~, the Series A Preferred Units are convertible by the preferred unitholders, at the preferred unitholders’ option, into common units on a one-for-one basis, adjusted to give effect to any accrued and unpaid distributions on the applicable preferred units.

At the option of the Partnership. The Partnership shall have the right to convert the Series A Preferred Units on a one-for-one basis, adjusted to give effect to any accrued and unpaid distributions on the applicable Series A Preferred Units, into common units at any time from and after January 1, 2023, if the closing price of the common units is greater than $33.082 per unit (140% of the Series A Preferred Unit Issue Price (as defined in the Second Amended and Restated Partnership Agreement)) for at least 20 trading days (whether or not consecutive) in a period of 30 consecutive trading days, including the last trading day of such 30 trading day period, ending on and including the trading day immediately preceding the date on which the Partnership sends notice to the holders of Series A Preferred Units of its election to convert such Series A Preferred Units. The conversion rate for the Series A Preferred Units shall be the quotient of (a) the sum of (i) $23.63, plus (ii) any unpaid cash distributions on the applicable Series A Preferred Units, divided by (b) $23.63.

1718

Voting

The Series A Preferred Units are entitled to vote on an as-converted basis with the common units and have certain other class voting rights with respect to any amendment to the Second Amended and Restated Partnership Agreement. In the event of any liquidation of the Partnership, the Series A Preferred Units are entitled to receive, out of the assets of the Partnership available for distribution to the partners or any assignees, prior and in preference to any distribution of any assets of any junior securities, the value in each holder’s capital account in respect of such Series A Preferred Units.

Change of Control

Upon the occurrence of certain events involving a change of control in which more than 90% of the consideration payable to the holders of the common units is payable in cash, the Series A Preferred Units will automatically convert into common units at the then-applicable conversion rate. Upon the occurrence of certain other events involving a change of control, the holders of the Series A Preferred Units may elect, among other potential elections, to convert the Series A Preferred Units to common units at the then-applicable conversion rate.

Special Distribution

Each Series A Preferred Unit has the right to share in any special distributions by the Partnership of cash, securities or other property pro rata with the common units or any other securities, on an as-converted basis, provided that special distributions shall not include regular quarterly distributions paid in the normal course of business on the common units.

Distributions to our Unitholders

The holders of the Series A Preferred Units are entitled to cumulative quarterly distributions at a rate of $0.2363 per Series A Preferred Unit, payable quarterly in arrears no later than 60 days after the end of the applicable quarter. The Partnership is not entitled to pay any distributions on any junior securities, including any of the common units, prior to paying the quarterly distribution payable to the Series A Preferred Units, including any previously accrued and unpaid distributions. For both the three and six months ended ~~March~~June 3130, 2022 and ~~March~~June 3130, 2021, the aggregate ~~and per unit~~ amounts of cumulative preferred distributions paid were $12 million and $24 million, respectively, and the per unit amounts were $0.2363 and $0.4726, respectively.

Under the Second Amended and Restated Partnership Agreement, our general partner or its assignee agreed to waive a portion of the distributions that would otherwise have been payable on the common units issued to SPLC as part of the transactions completed in April 2020, in an amount of $20 million per quarter for four consecutive fiscal quarters, beginning with the distribution made with respect to the second quarter of 2020 and ending with the distribution made with respect to the first quarter of 2021. See Note 23 — Related Party Transactions for terms of the Second Amended and Restated Partnership Agreement.

Distributions to Noncontrolling Interests

As a result of the ~~transaction completed in~~ May 2021 Transaction, SPLC no longer owns an interest in Zydeco. As such, for the three and six months ended ~~March~~June 3130, 2022 and the three months ended June 30, 2021, there was no distribution to SPLC for the noncontrolling interest that it previously held in Zydeco. Distributions to SPLC for its noncontrolling interest in Zydeco for the ~~three~~six months ~~ended March 31, 2021 were less~~

1819

ended June 30, 2021 were less than $1 million. For additional information on the ~~transaction completed in~~ May 2021 Transaction, refer to Note 32 – Acquisitions and Other Transactions ~~in the Notes to Consolidated Financial Statements in our 2021 Annual Report~~.

Distributions to GEL for its noncontrolling interest in Odyssey for the three and six months ended ~~March~~June 3130, 2022 were $3 million and ~~March~~$5 million, respectively, and for the three and six months ended June 3130, 2021 were $23 million and $47 million, respectively.

See Note 23 – Related Party Transactions for additional details.

89. Revenue Recognition

The revenue standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The revenue standard requires entities to recognize revenue through the application of a five-step model, which includes: identification of the contract; identification of the performance obligations; determination of the transaction price; allocation of the transaction price to the performance obligations; and recognition of revenue as the entity satisfies the performance obligations.

Disaggregation of Revenue

The following table provides information about disaggregated revenue by service type and customer type:

	Three Months Ended March 31,

(1) Transportation services revenue – related parties includes $1 million and $2 million, respectively, of non-lease service component in our transportation services contracts for both the three and six months ended ~~March~~June 3130, 2022 and ~~March~~June 3130, 2021.

(2) Terminaling services revenue – related parties is comprised of the service components in our terminaling services contracts, including the operation and maintenance service components related to the Norco Assets. See Note 23 – Related Party Transactions for additional details.

(3) Terminaling services revenue – major maintenance service – related parties is comprised of the major maintenance service components related the Norco Assets. See Note 23 – Related Party Transactions for additional details.

(4) Product revenue – related parties is comprised of allowance oil sales.

Lease revenue

Certain of our long-term transportation and terminaling services contracts with related parties are accounted for as operating leases. These agreements have both lease and non-lease service components. We allocate the arrangement consideration between the lease components and any non-lease service components based on the relative stand-alone selling price of each component. We estimate the stand-alone selling price of the lease and non-lease service components based on an analysis of service-related and lease-related costs for each contract, adjusted for a representative profit margin. The contracts have a minimum fixed monthly payment for both the lease and non-lease service components. We present the non-lease service components under the revenue standard within Transportation, terminaling and storage services – related parties in the unaudited consolidated statements of income.

Revenues from the lease components of these agreements are recorded within Lease revenue – related parties in the unaudited consolidated statements of income. Some of these agreements were entered into for terms of ten years, with the option for the lessee to extend for two additional five-year terms. One of these contracts was amended to include an option for the lessee to extend for a fourteen-month term prior to the original extension options. However, it is reasonably certain that the original extension options of the two additional five-year terms will not be exercised for this contract. Further, we have agreements with

1920

lessee to extend for two additional five-year terms. One of these contracts was amended to include an option for the lessee to extend for a fourteen-month term prior to the original extension options. However, it is reasonably certain that the original extension options of the two additional five-year terms will not be exercised for this contract. Further, we have agreements with initial terms of ten years with the option for the lessee to extend for up to ten additional one-year terms. As of ~~March~~June 3130, 2022, future minimum payments of both the lease and non-lease service components to be received under the ten-year contract term of these operating leases were estimated to be:

						Total						Less than 1 year						Years 2 to 3						Years 4 to 5						More than 5 years
Operating leases						$	~~590~~564					$	109					$	~~218~~219					$	~~218~~211					$	4525

Terminaling services revenue - Norco Assets

Certain of our terminaling service agreements entered into with SOPUS and Shell Chemical relate to the Norco Assets. These terminaling service agreements were entered into for an initial term of fifteen years, with the option to extend for an additional five-year term. The transfer of the Norco Assets, combined with the terminaling services agreements, were accounted for as a failed sale leaseback under the lease standard. The Partnership ~~receives~~initially received an annual net payment of $140 million, which is the total annual payment pursuant to the terminaling service agreements of $151 million, less $11 million, which primarily represents the allocated utility costs from SOPUS related to the Norco Assets. The terminaling service agreements contain an inflation escalation clause, pursuant to which the annual payments increase on July 1 of each year commencing on July 1, 2021. The inflation adjustment is based on the rate of change in the annual ~~Consumer Price Index (“~~CPI”) published by the U.S. Department of Labor’s Bureau of Labor Statistics. On July 1, 2021, the annual payments were escalated by applying a CPI adjustment of 4.86%. After such escalation, the Partnership ~~now~~ receives an annual net payment of $147 million, which is the total annual payment of $158 million, less $11 million related to the allocated utility costs from SOPUS.

These agreements have components related to financing receivables, for which the interest income is recognized in the unaudited consolidated statements of income and principal payments are recognized as a reduction to the financing receivables in the unaudited consolidated balance sheet. Revenue related to the service components are presented within Transportation, terminaling and storage services – related parties in the unaudited consolidated statements of income.

For additional information on the service types of revenue, refer to Note 12 – Revenue Recognition in the Notes to Consolidated Financial Statements in our 2021 Annual Report.

Contract Balances

The following table provides information about receivables and contract liabilities from contracts with customers:

	January 1, 2022		~~March~~June 3130, 2022
Receivables from contracts with customers – third parties	$	13	$	1013
Receivables from contracts with customers – related parties	35		3727
Contract assets – related parties	218		~~214~~210
Deferred revenue – third parties	2		43
Deferred revenue – related parties (1)	31		3639

(1) Deferred revenue – related parties is related to deficiency credits from certain minimum volume commitment contracts and certain components of our terminaling service contracts on the Norco Assets.

The contract assets represent the excess of the fair value embedded within the terminaling services agreements transferred by the Partnership to SOPUS and Shell Chemical as part of entering into the terminaling services agreements related to the Norco Assets. The contract assets balance is amortized in a pattern consistent with the recognition of revenue on the service components of the contract. The portion of the contract assets related to operations and maintenance is amortized on a straight-line basis over a fifteen-year period, and the portion related to major maintenance is amortized based on the ratio of actual major maintenance costs incurred to the total projected major maintenance costs over the fifteen-year term. We recorded amortization as a component of Transportation, terminaling and storage services – related parties of $43 million ~~for~~and ~~both~~$7 million, respectively, for the three and six months ended ~~March~~June 3130, 2022, and ~~March~~$4 million and $8 million, respectively for the three and six months ended June 3130, 2021. We had $~~214~~210 million and $218 million contract assets recognized from the costs to obtain or fulfill a contract as of ~~March~~June 3130, 2022 and December 31, 2021, respectively.

The estimated future amortization related to the contract assets for the next five years is as follows:

			Remainder of 2022						2023						2024						2025						2026						2027
Amortization			$	138					$	17					$	18					$	19					$	1617					$	16

Significant changes in the deferred revenue balances with customers during the period are as follows:

(1) Deferred revenue additions resulted from $9 million deficiency payments from minimum volume commitment contracts and $6 million of deferred revenue related to the major maintenance service components of our terminaling service contracts on the Norco Assets.

(1) Deferred revenue additions resulted from $6 million deficiency payments from minimum volume commitment contracts and $3 million of deferred revenue related to the major maintenance service components of our terminaling service contracts on the Norco Assets.

(2) Deferred revenue reductions resulted from revenue earned through the actual or estimated use and expiration of deficiency credits.

Remaining Performance Obligations

The following table includes revenue expected to be recognized in the future related to performance obligations exceeding one year of their initial terms that are unsatisfied or partially unsatisfied as of June 30, 2022:

(2) Relates to the operation and maintenance service components and the major maintenance service components of our terminaling service contracts on the Norco Assets.

As an exemption under the revenue standard, we do not disclose the amount of remaining performance obligations for contracts with an original expected duration of one year or less or for variable consideration that is allocated entirely to a wholly unsatisfied promise to transfer a distinct service that forms part of a single performance obligation.

910. Net Income Per Limited Partner Unit

Net income per unit applicable to common limited partner units is computed by dividing the respective limited partners’ interest in net income attributable to the Partnership for the period by the weighted average number of common units outstanding for the period. Since the Series A Preferred Units are not considered a participating security, our only class of participating securities is the common units. For the three and six months ended ~~March~~June 3130, 2022 and ~~March~~June 3130, 2021, our Series A Preferred Units were dilutive to net income per limited partner unit.

Net income earned by the Partnership is allocated between the classes of participating securities in accordance with the terms of the Second Amended and Restated Partnership Agreement, after giving effect to priority income allocations to the holders of the Series A Preferred Units. Earnings are allocated based on actual cash distributions declared to our unitholders, if applicable. To the extent net income attributable to the Partnership exceeds or is less than cash distributions, this difference is allocated based on the unitholders’ respective ownership percentages. For the diluted net income per limited partner unit calculation, the Series A Preferred Units are assumed to be converted at the beginning of the period into common limited partner units on a one-for-one basis, and the distribution formula for available cash is recalculated using the available cash amount increased only for the preferred distributions, which would have been attributable to the common units after conversion.

1011. Income Taxes

We are not a taxable entity for U.S. federal income tax purposes or for the majority of states that impose an income tax. Taxes on our net income are generally borne by our partners through the allocation of taxable income. Our income tax expense results from partnership activity in the state of Texas, as conducted by Zydeco, Sand Dollar and Triton. Income tax expense for both the three and six months ended ~~March~~June 3130, 2022 and ~~March~~June 3130, 2021 was not material.

With the exception of the operations of Colonial, Explorer and LOCAP, which are treated as corporations for federal income tax purposes, the operations of the Partnership are not subject to federal income tax.

1112. Commitments and Contingencies

Environmental Matters

We are subject to federal, state and local environmental laws and regulations. We routinely conduct reviews of potential environmental issues and claims that could impact our assets or operations. These reviews assist us in identifying environmental issues and estimating the costs and timing of remediation efforts. In making environmental liability estimations, we consider the material effect of environmental compliance, pending legal actions against us and potential third-party liability claims. Often, as the remediation evaluation and effort progresses, additional information is obtained, requiring revisions to estimated costs. These revisions are reflected in our income in the period in which they are probable and reasonably estimable. As of both ~~March~~June 3130, 2022 and December 31, 2021, these costs and any related liabilities are not material.

Legal Proceedings

We are named defendants in lawsuits and governmental proceedings that arise in the ordinary course of business. For each of our outstanding legal matters, we evaluate the merits of the case, our exposure to the matter, possible legal or settlement strategies and the likelihood of an unfavorable outcome. While there are still uncertainties related to the ultimate costs we may incur, based upon our evaluation and experience to date, we do not expect that the ultimate resolution of these matters will have a material adverse effect on our financial position, operating results or cash flows.

Other Commitments

Odyssey entered into a tie-in agreement effective January 2012 with a third party, which allowed producers to install the tie-in connection facilities and ~~tying~~tie-in ~~into~~to the system. The tie -in agreement will terminate in the ~~fourth~~third quarter of 2022, as the third party elected not to participate in the project on the Odyssey system ~~at MP289C~~ to re-route two pipelines around the MP289C platform.

~~Our~~Zydeco ~~Port~~entered ~~Neches~~into ~~storage tanks are subject to~~ a joint tariff agreement that became effective September 1, 2016. The tariff is reviewed annually and the rate updated based on the ~~Federal Energy Regulatory Commission’s (“~~FERC”) indexing adjustment to rates effective July 1 of each year. Effective July 1, 2021, there was an approximate 1% decrease to this rate based on the FERC’s indexing adjustment. The initial term of the agreement is ten years with automatic one-year renewal terms with the option to cancel prior to each renewal period.

We hold cancellable easements or rights-of-way arrangements from landowners permitting the use of land for the construction and operation of our pipeline systems. Obligations under these easements are not material to the results of our operations.

23On July 25, 2022, Shell USA, Inc., a Delaware corporation (“SUSA”), Shell Midstream LP Holdings LLC, a Delaware limited liability company and indirect wholly-owned subsidiary of SUSA (“Holdings”), Semisonic Enterprises LLC, a Delaware limited liability company and indirect wholly-owned subsidiary of SUSA (“Merger Sub”), the Partnership and the general partner entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Merger Sub will merge with and into the Partnership (the “Merger”), with the Partnership surviving and continuing to exist as a Delaware limited partnership, among other transactions contemplated by the Merger Agreement (such transactions, including the Merger, the “Transaction”). The conflicts committee, after evaluating the Transaction in consultation with its independent legal and financial advisors, unanimously approved, and recommended that the Board approve, the Transaction. Following receipt of the recommendation of the conflicts committee, the Board reviewed the terms of the Transaction, including the Merger Agreement, and unanimously approved the Transaction.

At the effective time of the Merger (the “Effective Time”), each common unit issued and outstanding (other than common units owned immediately prior to the Effective Time by SUSA and its affiliates, including Holdings) will be converted into the right to receive $15.85 per common unit in cash, without any interest thereon (“Merger Consideration”). In connection with the Merger, (i) the general partner’s non-economic general partner interest in the Partnership and (ii) the common units owned by SUSA and its affiliates, including Holdings, and the Series A Preferred Units shall not be cancelled, shall not be converted into or entitle the holder thereof to receive the Merger Consideration and shall remain outstanding following the Merger as a non-economic general partner interest in the Partnership, as common units and as Series A Preferred Units, respectively. After the Effective Time, the general partner intends to delist the common units from the New York Stock Exchange and, as promptly as possible, deregister them under the Exchange Act.

Concurrently with the execution of the Merger Agreement, Holdings delivered its written consent covering all of the common units and Series A Preferred Units beneficially owned by it approving the Merger Agreement and the Transaction (the “Written Consent”). The Written Consent was sufficient to approve the Merger Agreement and the Transaction, under the terms of the Second Amended and Restated Partnership Agreement, without the need for written consents from any other holders of common units.

The Transaction is expected to close by the fourth quarter of 2022. The Transaction is subject to a number of contingencies, including customary approvals and the satisfaction of conditions to the consummation of the Transaction as set forth in the Merger Agreement. There can be no assurance that the Transaction will be consummated on the terms described above or at all.

The foregoing summary of the Merger Agreement and the Transaction does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which is filed as Exhibit 2.1 to the Partnership’s Current Report on Form 8-K filed on July 25, 2022.

We will file with the SEC an information statement that will provide additional important information concerning the proposed Transaction. Since the proposed Transaction is a “going private” transaction under SEC rule 13e-3, we will also file with the SEC a transaction statement on Schedule 13E-3. After the information statement is cleared by the SEC, we will mail a definitive information statement to our common unitholders.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Shell Midstream Partners, L.P. (“we,” “us,” “our” or “the Partnership”) is a Delaware limited partnership formed by Shell plc on March 19, 2014 to own and operate pipeline and other midstream assets, including certain assets purchased from Shell Pipeline Company LP (“SPLC”) and its affiliates. We conduct our operations either through our wholly-owned subsidiary Shell Midstream Operating LLC or through direct ownership. Our general partner is Shell Midstream Partners GP LLC (the “general partner”). References to “Shell” or “Parent” refer collectively to Shell plc and its controlled affiliates, other than us, our subsidiaries and our general partner.

The following discussion and analysis should be read in conjunction with the unaudited consolidated financial statements and related notes in this quarterly report and Management’s Discussion and Analysis of Financial Condition and Results of Operations in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2021 (our “2021 Annual Report”) and the consolidated financial statements and related notes therein. Our 2021 Annual Report contains a discussion of other matters not included herein, such as disclosures regarding critical accounting policies and estimates and contractual obligations. You should also read the following discussion and analysis together with Risk Factors set forth in our 2021 Annual Report.

Partnership Overview

We own, operate, develop and acquire pipelines and other midstream assets and logistics assets. As of ~~March~~June 3130, 2022, our assets include interests in entities that own (a) crude oil and refined products pipelines and terminals that serve as key infrastructure to transport onshore and offshore crude oil production to Gulf Coast and Midwest refining markets and deliver refined products from those markets to major demand centers and (b) storage tanks and financing receivables that are secured by pipelines, storage tanks, docks, truck and rail racks and other infrastructure used to stage and transport intermediate and finished products. Our assets also include interests in entities that own natural gas and refinery gas pipelines that transport offshore natural gas to market hubs and deliver refinery gas from refineries and plants to chemical sites along the Gulf Coast.

For a description of our assets, please see Part I, Items 1 and 2. – Business and Properties in our 2021 Annual Report.

2022 developments include:

•Take Private Proposal. On February 11, 2022, the Board of Directors of our general partner (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. Refer to Note 113 – ~~Description~~Subsequent ofEvents ~~Business~~ – ~~Take~~Merger ~~Private~~Agreement ~~Proposal~~ in the Notes to the Unaudited Consolidated Financial Statements in this report for additional information.

•Credit Facilities. On February 16, 2022, we used excess cash to repay $150 million of borrowings under the Five Year Revolver due December 2022.

We generate revenue from the transportation, terminaling and storage of crude oil, refined products, and intermediate and finished products through our pipelines, storage tanks, docks, truck and rail racks, generate income from our equity and other investments, and generate interest income from financing receivables on certain logistics assets at the Shell Norco Manufacturing Complex (the “Norco Assets”). Our revenue is generated from customers in the same industry, our Parent’s affiliates, integrated oil companies, marketers and independent exploration, production and refining companies primarily within the Gulf Coast region of the United States. We generally do not own any of the crude oil, refinery gas or refined petroleum products we handle, nor do we engage in the trading of these commodities. We therefore have limited direct exposure to risks associated with fluctuating commodity prices, although these risks indirectly influence our activities and results of operations over the long-term.

Notable and certain anticipated 2022 impacts to net income and cash available for distribution (“CAFD”) include:

•Planned Turnarounds. Certain offshore connected producers will have planned turnarounds during 2022. We anticipate an impact of approximately $15 million to net income and CAFD from planned turnaround activity in 2022, of which approximately $14 million has been incurred in the six months ended June 30, 2022.

•Colonial Rate Case. Colonial is currently involved in a rate case with the Federal Energy Regulatory Commission (“FERC”). On April 27, 2022, the Administrative Law Judge issued a second partial initial decision ~~related to Colonial’s ongoing FERC rate case~~ addressing the issues not covered in the first partial initial decision ~~issued on December 1, 2021~~. Colonial ~~has~~is ~~begun~~reviewing ~~to review~~ the ~~decision.~~potential ~~Depending~~financial ~~upon~~impacts ~~the~~that ~~final~~could ~~outcome of the case, the~~

2426

result if the decision is adopted by the FERC in its forthcoming ruling. Depending upon the final outcome of the case, the potential adoption of such decision in whole or in part by the FERC could adversely affect our equity method investment in Colonial, net income and CAFD. Due in part to the anticipated impacts of the rate case on Colonial’s business, the board of directors of Colonial elected not to declare a dividend for the three months ended ~~March~~June 3130, 2022.

Throughout the first ~~quarter~~half of 2022, we have seen a significant increase in oil prices, most notably due to the ongoing Russian invasion of Ukraine and the associated impacts on the global markets. The responses of oil and gas producers to this situation, including as a result of government sanctions, is evolving and remains uncertain. As we navigate the current turbulent global environment, we anticipate continuing to moderate inorganic growth in our asset base and focusing on the sustainable operation of our core assets, cash preservation and the organic growth of our business throughout the remainder of 2022.

Executive Overview

Net income was $~~160~~311 million and net income attributable to the Partnership was $~~158~~306 million during the ~~three~~six months ended ~~March~~June 3130, 2022. We generated cash from operations of $~~157~~341 million. As of ~~March~~June 3130, 2022, we had cash and cash equivalents of $~~251~~325 million, total debt of $2,542 million and unused capacity under our credit facilities of $1,016 million.

Our 2022 operations and strategic initiatives demonstrate our continuing focus on our business strategies:

•Maintain operational excellence through prioritization of safety, reliability and efficiency;

•Enhanced focus on cash optimization and reduced discretionary project spend;

•Focus on advantageous commercial agreements with creditworthy counterparties to enhance financial results over the long-term; and

•Optimize existing assets and pursue organic growth opportunities.

Over the past two years, our business, as well as the market and economy as a whole, have dealt with unprecedented volatility and uncertainty. Even with these challenges, our assets have largely continued to deliver solid results that have allowed us to execute our business strategies. However, we continue to anticipate certain headwinds that may jeopardize our ability to generate sufficient cash to meet our quarterly obligations, including the pending FERC rate case at Colonial and ongoing uncertainty in the macro-environment. Further, the ~~conflicts committee appointed by the Board is currently evaluating the Proposal, and the~~ transactions ~~consummated~~contemplated by the Proposal, if consummated, ~~would~~will alter our capital structure. Refer to Note 113 – ~~Description~~Subsequent ofEvents ~~Business~~ – ~~Take~~Merger ~~Private~~Agreement ~~Proposal~~ in the Notes to the Unaudited Consolidated Financial Statements in this report for additional information.

To the extent the transactions contemplated by the Proposal are not consummated, identifying and executing acquisitions, whether from Shell or from third parties, will remain a key part of our strategy. However, if we do not make acquisitions on economically acceptable terms or if we incur a substantial amount of debt in connection with the acquisitions, our future growth will be limited, and the acquisitions we do make may reduce, rather than increase, our available cash. Our ability to obtain financing or access capital markets may also directly impact our ability to continue to pursue strategic acquisitions. Market demand for equity issued by master limited partnerships (“MLPs”) may make it more challenging for us to fund our acquisitions with the issuance of equity in the capital markets.

However, we believe our balance sheet offers us flexibility, providing us other financing options such as hybrid securities, purchases of common units by Shell and debt. While we expect to retain this flexibility, we anticipate continuing to moderate inorganic growth in our asset base and focusing on the sustainable operation of our core assets, cash preservation and organic growth of our business.

How We Evaluate Our Operations

Our management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability and include: (i) revenue (including pipeline loss allowance (“PLA”) from contracted capacity and throughput); (ii) operations and maintenance expenses (including capital expenses); (iii) net income attributable to the Partnership; (iv) Adjusted EBITDA (defined below); and (v) CAFD.

Contracted Capacity and Throughput

The amount of revenue our assets generate primarily depends on our transportation and storage services agreements with shippers and the volumes of crude oil, refinery gas and refined products that we handle through our pipelines, terminals and storage tanks.

25The commitments under our transportation, terminaling and storage services agreements with shippers and the volumes we handle in our pipelines and storage tanks are primarily affected by the supply of, and demand for, crude oil, refinery gas, natural

The commitments under our transportation, terminaling and storage services agreements with shippers and the volumes we handle in our pipelines and storage tanks are primarily affected by the supply of, and demand for, crude oil, refinery gas, natural gas and refined products in the markets served directly or indirectly by our assets. This supply and demand is impacted by the market prices for these products in the markets we serve. The ongoing Russian invasion of Ukraine and the associated impacts on the global markets has caused, and may continue to cause, disruptions in the U.S. economy and financial and energy markets. Responses of oil and gas producers to the changes in demand for, and price of, oil and natural gas are constantly evolving and unpredictable.27

gas and refined products in the markets served directly or indirectly by our assets. This supply and demand is impacted by the market prices for these products in the markets we serve. The ongoing Russian invasion of Ukraine and the associated impacts on the global markets have caused, and may continue to cause, disruptions in the U.S. economy and financial and energy markets. Responses of oil and gas producers to the changes in demand for, and price of, oil and natural gas are constantly evolving and unpredictable.

We utilize the commercial arrangements we believe are the most prudent under the market conditions to deliver on our business strategy. The results of our operations will be impacted by our ability to:

•maintain utilization of and rates charged for our pipelines and storage facilities;

•utilize the remaining uncommitted capacity on, or add additional capacity to, our pipeline systems;

•increase throughput volumes on our pipeline systems by making connections to existing or new third-party pipelines or other facilities, primarily driven by the anticipated supply of, and demand for, crude oil and refined products; and

•identify and execute organic expansion projects.

Operations and Maintenance Expenses

Our operations and maintenance expenses consist primarily of:

•labor expenses (including contractor services);

•insurance costs (including coverage for our consolidated assets and operated joint ventures);

•utility costs (including electricity and fuel);

•repairs and maintenance expenses; and

•major maintenance costs (related to the terminaling service agreements of the Norco Assets, which are expensed as incurred because the Partnership does not own the related assets).

Certain costs naturally fluctuate based on throughput volumes and the grades of crude oil and types of refined products we handle, whereas other costs generally remain stable across broad ranges of throughput and storage volumes, but can vary depending upon the level of both planned and unplanned maintenance activity in the particular period. Our maintenance activity can be impacted by events such as turnarounds, asset integrity work and storms.

Our management seeks to maximize our profitability by effectively managing operations and maintenance expenses. While cost effectiveness has always been a focus of the business, it is of increased importance given the current operating environment.

Adjusted EBITDA and Cash Available for Distribution

Adjusted EBITDA and CAFD have important limitations as analytical tools because they exclude some, but not all, items that affect net income and net cash provided by operating activities. You should not consider Adjusted EBITDA or CAFD in isolation or as a substitute for analysis of our results as reported under generally accepted accounting principles in the United States (“GAAP”). Additionally, because Adjusted EBITDA and CAFD may be defined differently by other companies in our industry, our definition of Adjusted EBITDA and CAFD may not be comparable to similarly-titled measures of other companies, thereby diminishing their utility.

The GAAP measures most directly comparable to Adjusted EBITDA and CAFD are net income and net cash provided by operating activities. Adjusted EBITDA and CAFD should not be considered as an alternative to GAAP net income or net cash provided by operating activities. Please refer to “Results of Operations - Reconciliation of Non-GAAP Measures” for the reconciliation of GAAP measures net income and cash provided by operating activities to non-GAAP measures, Adjusted EBITDA and CAFD.

We define Adjusted EBITDA as net income before income taxes, interest expense, interest income, gain or loss from dispositions of fixed assets, allowance oil reduction to net realizable value, loss from revision of asset retirement obligation, and depreciation, amortization and accretion, plus cash distributed to us from equity method investments for the applicable period, less equity method distributions included in other income and income from equity method investments. We define Adjusted EBITDA attributable to the Partnership as Adjusted EBITDA less Adjusted EBITDA attributable to noncontrolling interests and Adjusted EBITDA attributable to Parent.

We define CAFD as Adjusted EBITDA attributable to the Partnership less maintenance capital expenditures attributable to the Partnership, net interest paid by the Partnership, cash reserves, income taxes paid and distributions on our Series A perpetual convertible preferred units (the “Series A Preferred Units”), plus net adjustments from volume deficiency payments attributable to the Partnership, reimbursements from Parent included in partners’ capital, principal and interest payments received on financing receivables and certain one-time payments received. CAFD will not reflect changes in working capital balances.

to the Partnership, reimbursements from Parent included in partners’ capital, principal and interest payments received on financing receivables and certain one-time payments received. CAFD will not reflect changes in working capital balances.

We believe that the presentation of these non-GAAP supplemental financial measures provides useful information to management and investors in assessing our financial condition and results of operations.

Adjusted EBITDA and CAFD are non-GAAP supplemental financial 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 our unitholders;

•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 various investment opportunities.

Factors Affecting Our Business and Outlook

We believe key factors that impact our business are the supply of, and demand for, crude oil, natural gas, refinery gas and refined products in the markets in which our business operates. We also believe that our customers’ requirements, competition and government regulation of crude oil, refined products, natural gas and refinery gas play an important role in how we manage our operations and implement our long-term strategies. In addition, acquisition opportunities, whether from Shell or third parties, and financing options, will also impact our business. These factors are discussed in more detail below.

Changes in Crude Oil Sourcing and Refined Product Demand Dynamics

To effectively manage our business, we monitor our market areas for both short-term and long-term shifts in crude oil and refined products supply and demand. Changes in crude oil supply such as new discoveries of reserves, declining production in older fields, operational impacts at producer fields and the introduction of new sources of crude oil supply affect the demand for our services from both producers and consumers. In addition, general economic, regulatory, broad market and worldwide health considerations can also affect sourcing and demand dynamics for our services. This includes, but is not limited to, the impacts resulting from the ongoing Russian invasion of Ukraine, as well as the lingering effects of the COVID-19 pandemic.

One of the strategic advantages of our crude oil pipeline systems is their ability to transport attractively priced crude oil from multiple supply markets to key refining centers along the Gulf Coast. Our crude oil shippers periodically change the relative mix of crude oil grades delivered to the refineries and markets served by our pipelines. They also occasionally choose to store crude longer term when the forward price is higher than the current price (a “contango market”). While these changes in the sourcing patterns of crude oil transported or stored are reflected in changes in the relative volumes of crude oil by type handled by our pipelines, our total crude oil transportation revenue is primarily affected by changes in overall crude oil supply and demand dynamics, such as the impacts resulting from the ongoing Russian invasion of Ukraine, as well as U.S. exports.

Similarly, our refined products pipelines have the ability to serve multiple major demand centers. Our refined products shippers periodically change the relative mix of refined products shipped on our refined products pipelines, as well as the destination points, based on changes in pricing and demand dynamics. While these changes in shipping patterns are reflected in relative types of refined products handled by our various pipelines, our total product transportation revenue is primarily affected by changes in overall refined products supply and demand dynamics, including the impacts resulting from the ongoing Russian invasion of Ukraine. Demand can also be greatly affected by refinery performance in the end market, as refined products pipeline demand will increase to fill the supply gap created by refinery issues.

We can also be constrained by asset integrity considerations in the volumes we ship. We may elect to reduce cycling on our systems to reduce asset integrity risk, which in turn would likely result in lower revenues.

As these supply and demand dynamics shift, we anticipate that we will continue to actively pursue projects that link new sources of supply to producers and consumers and to create new services or capacity arrangements that meet customer requirements. We expect to continue extending our corridor pipelines to provide developing growth regions in the Gulf of Mexico with access via our existing corridors to onshore refining centers and market hubs. For example, the Mars system is expanding to address growing production volumes in the Gulf of Mexico regions served by Mars. It is expected that the project will be fully operational in 2022. Incremental growth volumes began arriving into the Mars system in the first quarter of 2022, and we expect additional growth volumes to arrive into the system in the latter part of 2022, and continuing into 2023. We believe this strategy will allow our offshore business to grow profitably throughout demand cycles.

2729

Changes in Customer Contracting

We generate a portion of our revenue under long-term transportation service agreements with shippers, including ship-or-pay agreements and life-of-lease transportation agreements, some of which provide a guaranteed return, and storage service agreements with marketers, pipelines and refiners. Historically, the commercial terms of these long-term transportation and storage service agreements have mitigated volatility in our financial results by limiting our direct exposure to reductions in volumes due to supply or demand variability. Our business could be negatively affected if we are unable to renew or replace our contract portfolio on comparable terms, by sustained downturns or sluggishness in commodity prices, or the economy in general. Our business is also impacted by shifts in supply and demand dynamics, the mix of services requested by our pipeline customers, competition and changes in regulatory requirements affecting our operations. Other factors that can have an effect on our performance include asset integrity or customer interruptions, natural disasters or other events that could lead customers or connecting carriers to invoke force majeure or other defenses to avoid contractual performance.

As contracts expire, there are several ways in which the associated revenue could be replaced in the future, such as through re-contracting or spot shipments, the outcome of which will be dependent on market and customer dynamics. The market environment at any given time will dictate the rates, terms and duration of agreements that shippers are willing to enter into, as well as the contracts that best satisfy the needs of our business and that will maximize earnings. As we have grown and broadened our business over the past several years, we have benefited from shifting our reliance away from the results of any one asset. For example, while Zydeco continues to serve an important market, and we strive to maximize the long-term value of the system to both shippers and the pipeline, we have diversified, and will continue to diversify, our risk across products, customers and geographies.

Changes in Commodity Prices and Customers’ Volumes

Crude oil prices have fluctuated significantly over the past few years, often with drastic moves in relatively short periods of time. While we saw an increase in both the demand for and price of crude oil throughout 2021, and a significant increase in price in the first ~~few~~half ~~months~~ of 2022, it is not without continued uncertainty. Current global geopolitical and economic instability, particularly as it relates to the ongoing Russian invasion of Ukraine, continues to contribute to future uncertainty, and potential volatility, in financial and commodity markets. One example of such global economic forces impacting crude oil prices was the stalemate among Organization of Petroleum Exporting Countries (“OPEC”) members and co-operating non-OPEC resource holders (the “OPEC+ alliance”), which ultimately ended in mid-2021 and was resolved when the OPEC+ alliance agreed to phase out the COVID-19 production cuts from August 2021 to December 2022. We expect that the OPEC+ alliance decision will cause the crude oil market to remain relatively tight in the near and medium-term, as this increased production will likely align with the higher global demand. The ongoing Russian invasion of Ukraine and resulting sanctions imposed on Russia by the European Union, the United States and other countries have further tightened the crude oil market and elevated commodity prices. Although such sanctions do not directly impact our business or our customers, the effects of these measures may indirectly affect our business by affecting the price of crude oil, natural gas, refinery gas and refined products. Additionally, in order to address high oil prices, in March 2022 President Biden ~~recently~~ announced a plan to release 1 million barrels of oil a day for ~~the~~a ~~next~~period of 6 months from the U.S. Strategic Petroleum Reserve. The release from the U.S. Strategic Petroleum Reserve iswas ~~anticipated to start being~~ available in the market beginning in May 2022. While the scope of impact on commodity prices is ~~currently~~somewhat unclear, the continued release could have a downward effect ~~on commodity prices~~.

Our direct exposure to commodity price fluctuations is limited to the PLA provisions in our tariffs. Indirectly, global demand for refined products and chemicals could impact our terminal operations and refined products and refinery gas pipelines, as well as our crude pipelines that feed U.S. manufacturing demand. Likewise, changes in the global market for crude oil could affect our crude oil pipelines and terminals and require expansion capital expenditures to reach growing export hubs. Demand for crude oil, refined products and refinery gas may decline in the areas we serve as a result of decreased production by our customers, depressed commodity prices, decreased third-party investment in the industry, increased competition and other adverse economic factors. Other global events, such as the ongoing Russian invasion of Ukraine and its associated impacts on the global markets, as well as the lingering impacts of the COVID-19 pandemic, could affect the exploration, production and refining industries generally, which, indirectly, may affect our business. However, fixed contracts with volume minimums and demand for tanks for storage are expected to moderate any impact on our terminaling and storage service revenue.

Certain of our assets benefit from long-term fee-based arrangements and are strategically positioned to connect crude oil volumes originating from key onshore and offshore production basins to the Texas and Louisiana refining markets, where demand for throughput has remained strong. Historically, with the exception of the impacts of the COVID-19 pandemic, we have not experienced a material decline in throughput volumes on our crude oil pipeline systems as a result of lower crude oil prices. If crude oil prices drop to lower levels, as they did during the height of the COVID-19 pandemic, we will see a reduction in our transportation volumes if production coming into our systems is deferred and our associated allowance oil sales decrease. Our customers may also experience liquidity and credit problems or other unexpected events, which could cause them to defer development or repair projects, avoid our contracts in bankruptcy, invoke force majeure clauses or other defenses to avoid

2830

contractual performance, renegotiate our contracts on terms that are less attractive to us or impair their ability to perform under our contracts.

Our throughput volumes on our refined products pipeline systems depend primarily on the volume of refined products produced at connected refineries and the desirability of our end markets. These factors in turn are driven by refining margins, maintenance schedules and market differentials. Refining margins depend on the cost of crude oil or other feedstocks and the price of refined products. These margins are affected by numerous factors beyond our control, including the domestic and global supply of and demand for crude oil and refined products.

Other Changes in Customers’ Volumes

Onshore crude transportation volumes were lower in the three months ended ~~March~~June 3130, 2022 (the “Current Quarter”) and the six months ended June 30, 2022 (the “Current Period”) versus the three months ended ~~March~~June 3130, 2021 (the “Comparable Quarter”) and the six months ended June 30, 2021 (the “Comparable Period”) primarily due to ~~lower~~the ~~deliveries~~expiration ~~from~~of ~~certain~~a ~~systems~~shipper ~~into~~contract ~~Houma~~ in the Current Quarter,. The decrease was partially offset by ~~the~~increased ~~impact~~shipper ofactivity on the ~~COVID-19~~remaining ~~pandemic~~contracts and an increase in ~~the~~deliveries ~~Comparable~~into ~~Quarter~~Houma from certain offshore systems.

Offshore crude transportation volumes were lower in the Current Quarter and Current Period versus the Comparable Quarter and Comparable Period primarily due to ~~lower~~planned ~~deliveries~~turnaround ~~from certain connected producers, as well as higher maintenance~~ activities on various systems in the central and eastern ~~corridor~~corridors of the Gulf Coast, and lower deliveries from certain connected producers.

Onshore terminaling and storage volumes decreased in the Current Quarter and Current Period versus the Comparable Quarter and Comparable Period due to scheduled maintenance at the Lockport facility, as well as connecting carrier availability.

Major Maintenance Projects

A project is being completed on the Odyssey system ~~at MP289C~~ to re-route two pipelines around the MP289C platform. We expect that the re-route work will be complete by mid-2023. The project ~~will~~is bebeing funded by cash calls to the owners of Odyssey for their proportionate share. As such, we will fund 71% of the project.

For expected capital expenditures in 2022, refer to Capital Resources and Liquidity – Capital Expenditures and Investments.

Major Expansion Projects

The Mars system is expanding to address growing production volumes in the Gulf of Mexico regions served by Mars. SPLC has elected to fund the installation of the equipment necessary to enable greater throughput volumes on the system, but the revenue associated with increased throughput volumes will benefit Mars. Two major milestones were reached in 2021 with the placement of the pump module on the platform and the execution of definitive agreements with producers. It is expected that the project will be fully operational in 2022. Incremental growth volumes began arriving into the Mars system in the first quarter of 2022 with the startup of PowerNap, a tie-back to the Shell-operated Olympus production hub. We expect additional growth volumes to arrive into the system in the latter part of 2022, and continuing into 2023.

Over the course of the next few years, we are considering expanding the Auger corridor in order to position the system to capture potential growth volumes in that region of the Gulf of Mexico.

We also intend to expand our Lockport facility to accommodate expected additional volumes coming into the Midwest region. This expansion is pending the completion of certain commercial agreements.

Customers

We transport and store crude oil, refined products, natural gas and refinery gas for a broad mix of customers, including producers, refiners, marketers and traders, and are connected to other crude oil and refined products pipelines. In addition to serving directly-connected U.S. Gulf Coast markets, our crude oil and refined products pipelines have access to customers in various regions of the United States through interconnections with other major pipelines. Our customers use our transportation and storage services for a variety of reasons. Refiners typically require a secure and reliable supply of crude oil over a prolonged period of time to meet the needs of their specified refining diet and frequently enter into long-term firm transportation agreements to ensure a ready supply of a specific mix of crude oil grades, rate surety and sometimes sufficient transportation capacity over the life of the contract. Similarly, chemical sites require a secure and reliable supply of refinery gas to crackers and enter into long-term firm transportation agreements to ensure steady supply. Producers of crude oil and natural gas require the ability to deliver their product to market and frequently enter into firm transportation contracts to ensure that they will have sufficient capacity available to deliver their product to delivery points with greater market liquidity. Marketers and traders generate income from buying and selling crude oil and refined products to capitalize on price differentials over time or between markets. Our customer mix can vary over time and largely depends on the crude oil and refined products supply and demand dynamics in our markets.

Competition

Our pipeline systems compete primarily with other interstate and intrastate pipelines and with marine and rail transportation. Some of our competitors may expand or construct transportation systems that would create additional competition for the services we provide to our customers. For example, newly-constructed transportation systems in the onshore Gulf of Mexico region may increase competition in the markets where our pipelines operate. In addition, future pipeline transportation capacity could be constructed in excess of actual demand in the market areas we serve, which could reduce the demand for our services, and could lead to the reduction of the rates that we receive for our services. While we do see some variation from quarter-to-quarter resulting from changes in our customers’ demand for transportation, we have historically been able to partially mitigate this risk with the longer-term, fixed-rate nature of several of our contracts.

Our storage terminal competes with surrounding providers of storage tank services. Some of our competitors have expanded terminals and built new pipeline connections, and third parties may construct pipelines that bypass our location. These, or similar events, could have a material adverse impact on our operations.

Our refined products terminals generally compete with other terminals that serve the same markets. These terminals may be owned by major integrated oil and gas companies or by independent terminaling companies. While fees for terminal storage and throughput services are not regulated, they are subject to competition from other terminals serving the same markets. However, our contracts provide for stable, long-term revenue, which is not impacted by market competitive forces.

Regulation

Our assets are subject to regulation by various federal, state and local agencies; for example, our interstate common carrier pipeline systems are subject to economic regulation by the FERC. Intrastate pipeline systems are regulated by the appropriate state agency.

On April 8, 2022, the Pipeline and Hazardous Materials Safety Administration (“PHMSA”) published a new final rule titled “Required valve installation and minimum rupture detection standards.” This rule has amendments to both the liquid and gas pipeline safety regulations around valve placement and rupture/leak detection. The majority of the requirements regarding valve placement and rupture detection in this new rule apply to new construction or pipeline replacements. There are some provisions around emergency response and emergency notifications that apply to all regulated lines. The rule is being reviewed to determine the impact to our operations, and an action plan will be created to adjust processes and procedures as needed for compliance with the rule.

We are also subject to various cybersecurity requirements, including recent changes as a result of the May 2021 cyberattack impacting Colonial. We have a 16.125% ownership interest in Colonial, which owns and operates a pipeline that runs throughout the southern and eastern United States (the “Colonial pipeline”). On May 7, 2021, the computerized equipment managing the Colonial pipeline was the target of a cyberattack, and while Colonial proactively took certain systems offline to contain the threat, it paid a ransom in the form of cryptocurrency to regain control of the equipment. For additional information about cybersecurity risks and the cybersecurity programs and protocols we have in place to protect against those risks, see Part I, Items 1 and 2. Business and Properties – Information Technology and Cyber-security and Item 1A. Risk Factors – IT/Cyber-security/Data Privacy/Terrorism Risks in our 2021 Annual Report.

Business and Properties – Information Technology and Cyber-security and Item 1A. Risk Factors – IT/Cyber-security/Data Privacy/Terrorism Risks in our 2021 Annual Report.32

In May 2021, the Transportation Security Administration (“TSA”) issued a security directive, ~~their~~which was its initial regulatory response to the Colonial pipeline ransomware attack. The first security directive requires pipeline owners and operators to report confirmed and potential cybersecurity incidents to the Cybersecurity and Infrastructure Security Agency (“CISA”) within 12 hours of discovery, designate a cybersecurity coordinator to be available 24 hours a day, seven days a week, review current practices and identify any gaps and related remediation measures to address cyber-related risks and report the results to the TSA and CISA within 30 days.

30In July 2021, the TSA issued a second security directive imposing additional obligations on owners and operators of TSA-designated critical pipelines. In addition to the requirements under the first directive, the second directive requires pipeline owners and operators to develop and implement specific mitigation measures to protect against ransomware attacks and other known threats to information technology and operational technology systems, develop and implement a cybersecurity contingency and recovery plan, as well as to conduct cybersecurity assessments.

On May 29, 2022, having received feedback from us and ~~potential~~other ~~cybersecurity~~industry ~~incidents~~participants, tothe TSA issued a revised version of the ~~Cybersecurity~~first ~~and~~security ~~Infrastructure~~directive, ~~Security~~revising ~~Agency~~the (“reporting period for cybersecurity incidents to CISA”) within 1224 hours of discovery.

On June 14, 2021, as part of the self-executing provisions of the Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2020, PHMSA published an advisory bulletin requiring operators to update inspection and maintenance plans to address eliminating hazardous leaks and minimizing releases of natural gas by December 27, 2021. This advisory bulletin is expected to have minimal impact on our operations but will require minor updates to our inspection and maintenance manuals.

In early 2021, PHMSA issued a revised map of the ecological High Consequence Areas (“HCAs”) in the Gulf of Mexico. This revised map expanded the ecological HCA of the Gulf of Mexico to include previously excluded dolphin and whale habitats. The HCA now encompasses most of the Gulf of Mexico. This places most liquid pipelines in the Gulf of Mexico in an HCA and subject to the assessment requirements of 49 CFR 195.452. This may impact certain operational activity such as the frequency at which certain inspections need to be performed and the types of inspections required at those intervals. The holistic impact to our business is uncertain at this time, but we expect that all companies with comparable Gulf of Mexico operations will be similarly impacted.

In May 2021, Zydeco, Mars and LOCAP filed with the FERC to decrease rates subject to the FERC’s indexing adjustment methodology that were previously at their ceiling levels by 0.5812% starting on July 1, 2021. On January 20, 2022, the FERC filed an order requiring carriers to recalculate their ceiling levels and file any necessary rate reductions to be effective March 1, 2022 using a revised formula. All the FERC ceiling levels were recalculated as directed and necessary rate reductions filed before the March 1 deadline.

Rate complaints are currently pending at the FERC in Docket Nos. OR18-7-002, et al. challenging Colonial’s tariff rates, its market power and its practices and charges related to transmix and product volume loss. A partial initial decision from the Administrative Law Judge was issued on December 1, 2021 finding that Colonial lacks the ability to exercise market power in the 90-county Gulf Coast geographic origin market, but no longer lacks the ability to exercise market power in the 16-county Tuscaloosa-Moundville geographic origin market. The partial initial decision also found that Colonial’s method of net recoveries of product loss is unjust and unreasonable and that Colonial should adopt a fixed allowance oil deduction for shortages in deliveries and determine the amount of reparations, if any, owed to shippers. This document is a recommendation to the FERC based on the facts surrounding the case, the law and FERC precedent. The FERC may decide to adopt the recommendations made or make different determinations. If the FERC adopts the partial initial decision in whole, in addition to the changes in product loss charges described above, which may adversely affect Colonial, Colonial’s rates in respect of the 16-county Tuscaloosa-Moundville geographic origin market will no longer be market-based and could be reduced. Subsequently, on April 27, 2022, the Administrative Law Judge issued a second partial initial decision ~~related to Colonial’s ongoing FERC rate case~~ addressing the issues not covered in the first partial initial decision. ~~issued~~The onparties ~~December~~to 1,the ~~2021.~~case ~~Colonial~~filed ~~has~~briefs ~~begun~~on ~~to review~~ the ~~decision.~~recommendations ~~The~~in ~~parties~~June to2022 ~~the~~and ~~case~~ will be filing reply briefs toin ~~argue~~August ~~for~~2022. orColonial ~~against~~continues ~~the~~to ~~recommendations,~~review ~~which will be considered by~~ the ~~FERC~~decision in ~~its~~preparation ~~ruling.~~for ~~The~~filing ~~timing~~reply ofbriefs ~~such~~and ~~ruling~~to isevaluate ~~unknown.~~the

In 2020, the FERC commenced the five-year review of the oil pipeline rate index formula in Docket No. RM20-14-000. The FERC issued an initial order on December 17, 2020 adopting a new formula of PPI-FG plus 0.78% for the next five-year period commencing on July 1, 2021. On January 20, 2022, the FERC issued an order on rehearing revising the formula set in the December 17, 2020 order to PPI-FG minus 0.21%. The lower indexing adjustment resulted from the FERC adjusting the data set used to assess pipeline cost changes; taking into account the elimination of the income tax allowance and previously accrued accumulated deferred income tax balances for MLP-owned pipelines; and using updated cost data for 2014. The rehearing order required pipelines to recalculate their rate ceiling levels using the PPI-FG minus 0.21% formula for the period July 1, 2021 to June 30, 2022. For any rate that exceeded the recalculated ceiling level, the pipeline was required to file a rate reduction with the FERC to be effective March 1, 2022. A judicial appeal on the FERC’s order on rehearing has been filed with the U.S. Court of Appeals for the Fifth Circuit by a group of carriers. Similarly, a group of shippers filed a request for rehearing at the FERC, and the FERC issued a tolling order to extend its time to consider the matter. The FERC filed a motion to hold the matter in abeyance at the Fifth Circuit until it was ruled on the rehearing request. We do not expect these rate recalculations to have a material effect on our financial position, operating results or cash flows.33

Judicial appeals of the FERC’s order on rehearing have been filed with the U.S. Court of Appeals for the Fifth Circuit and in the U.S. Court of Appeals for the District of Columbia Circuit. The Fifth Circuit issued an order on May 11, 2022 that approved the transfer of this petition to the D.C. Circuit Court, although certain parties have sought review of that order by the Fifth Circuit en banc. Once the matters regarding venue are resolved, the case is expected to proceed. We do not expect these rate recalculations to have a material effect on our financial position, operating results or cash flows.

Additionally, there was lower throughput on Odyssey in the ~~second~~Current ~~quarter~~Quarter, primarily as a result of ~~2021~~lower deliveries from producers. Lastly, there was lower transportation services revenue on Pecten primarily as a result of lower throughput largely due to planned maintenance activities from producers in the Current Quarter. These decreases were partially offset by an increase in deliveries into Houma from certain offshore systems, as well as an overall increase in allowance oil prices in the Current Quarter.

Terminaling services revenue increased primarily due to higher revenue resulting from a contractual inflation adjustment in the latter part of 2021 related to the service components of the terminaling services agreements for the Norco Assets.

Costs and Expenses

Total costs and expenses increased $57 million in the Current Quarter as compared to the Comparable Quarter primarily due to an increase of $37 million of ~~operations~~cost ~~and~~of ~~maintenance~~product ~~expenses~~sold, $51 million of ~~cost~~general ofand ~~product~~administrative ~~sold~~expenses and $1 million of ~~general~~depreciation ~~and administrative expenses~~expense. These increases were partially offset by decreases of $31 million ~~as a result~~ of nooperations ~~impairment~~and ofmaintenance ~~fixed~~expenses ~~assets in Current Quarter~~ and $1 million of ~~depreciation~~property ~~expense.~~and other taxes.

Operations and maintenance expenses increased in the Current Quarter versus the Comparable Quarter mainly as a result of higher project spend and maintenance activities in the Current Quarter, partially offset by larger physical gains on allowance oil in the Current Quarter.

Cost of product sold increased primarily as a result of higher sales of allowance oil in the Current Quarter as compared to the Comparable Quarter.

General and administrative expenses increased in the Current Quarter versus the Comparable Quarter primarily due to an increase in professional services and associated fees.

Operations and maintenance expenses decreased in the Current Quarter versus the Comparable Quarter primarily due to larger physical gains on allowance oil in the Current Quarter, as well as lower non-routine maintenance expenses on the Norco Assets. This decrease was almost entirely offset by higher project spend across various assets.

Property tax expense decreased as a result of changes in property tax appraisal estimates.

Investment and Other Income

Investment and other income ~~increased~~decreased $29 million in the Current Quarter as compared to the Comparable Quarter.

Current Period compared to Comparable Period

Revenues

Total revenue decreased by $3 million in the Current Period as compared to the Comparable Period comprised of decreases of $17 million attributable to transportation services revenue and $1 million attributable to lease revenue. These decreases were partially offset by increases of $14 million in product revenue and $1 million in terminaling services revenue in the Current Period versus the Comparable Period.

Transportation services revenue decreased for Pecten primarily due to planned maintenance activities on certain systems in the Current Period. Transportation services revenue also decreased as a result of the expiration of a shipper contract on the Zydeco system in the Current Period, coupled with lower average tariff rates for the mix of barrels shipped in the Current Period versus the Comparable Period, as well as lower overall spot shipments in the Current Period. These decreases were partially offset by an overall increase in allowance oil prices in the Current Period.

Lease revenue decreased as a result of the sale of the Anacortes Assets in the Comparable Period.

Product revenue increased by $14 million related to higher sales of allowance oil for certain of our onshore and offshore crude pipelines in the Current Period as compared to the Comparable Period.

Terminaling services revenue increased as a result of a contractual inflation adjustment in the latter part of 2021 related to the service components of the terminaling services agreements for the Norco Assets.

Costs and Expenses

Total costs and expenses increased $12 million in the Current Period as compared to the Comparable Period primarily due to an increase of $12 million of cost of product sold, $2 million of operations and maintenance expenses and $2 million of general and administrative expenses. These increases were partially offset by decreases of $3 million as a result of no impairment of fixed assets in Current Period and a decrease of $1 million of property and other taxes.

Cost of product sold increased due to higher sales of allowance oil in the Current Period as compared to the Comparable Period.

Operations and maintenance expenses increased in the Current Period as compared to the Comparable Period mainly as a result of higher project spend and maintenance activities in the Current Period. This increase was partially offset by larger physical gains on allowance oil in the Current Period.

General and administrative expense increased primarily due to an increase in professional services and associated fees.

Property tax expense decreased as a result of changes in property tax appraisal estimates.

Investment and Other Income

Investment and other income decreased $7 million in the Current Period as compared to the Comparable Period. Other income decreased by $5 million related to $7 million of lower distributions from Poseidon in the Current Period, partially offset by the receipt of $2 million of insurance proceeds in the Current Period related to hurricane impacts in the third quarter of 2021. Income from equity method investments decreased by $2 million primarily as a result of lower equity earnings from Explorer, partially offset by higher equity earnings from Colonial.

Interest Income and Expense

Interest income and interest expense both increased $1 million in the Current Period as compared to the Comparable Period mainly due to higher interest rates in the Current Period versus the Comparable Period.

Capital Resources and Liquidity

We expect our ongoing sources of liquidity to include cash generated from operations, borrowings under our credit facilities and our ability to access the capital markets. We believe this access to credit along with cash generated from operations will be sufficient to meet our short-term working capital requirements and long-term capital expenditure requirements and to make quarterly cash distributions. Our liquidity as of ~~March~~June 3130, 2022 was $1,~~267~~341 million, consisting of $~~251~~325 million cash and cash equivalents and $1,016 million of available capacity under our credit facilities.

Credit Facility Agreements

As of ~~March~~June 3130, 2022, we have entered into the following credit facilities:

	Total Capacity		Current Interest Rate		Maturity Date
2021 Ten Year Fixed Facility	$	600	2.96	%	March 16, 2031
Ten Year Fixed Facility	600		4.18	%	June 4, 2029
Seven Year Fixed Facility	600		4.06	%	July 31, 2025
Five Year Revolver due July 2023 (1)	760		12.2517	%	July 31, 2023
Five Year Revolver due December 2022 (1)	1,000		12.2618	%	December 1, 2022

(1) These revolving credit facilities will expire in 2022 and 2023, respectively, and as such, we are currently assessing our options for renewal.

On June 30, 2021, Zydeco entered into a termination of revolving loan facility agreement with Shell Treasury Center (West) Inc. (“STCW”) to terminate the 2019 Zydeco Revolver. Zydeco had not borrowed any funds under this facility, and therefore, no further obligations existed at the time of termination.

On March 16, 2021, we entered into a ten-year fixed rate credit facility with STCW with a borrowing capacity of $600 million (the “2021 Ten Year Fixed Facility”). The 2021 Ten Year Fixed Facility bears an interest rate of 2.96% per annum and matures on March 16, 2031. The 2021 Ten Year Fixed Facility was fully drawn on March 23, 2021, and the borrowings were used to repay the borrowings under, and replace, the Five Year Fixed Facility. Refer to Note 56 – Related Party Debt in the Notes to the Unaudited Consolidated Financial Statements in this report for additional information.

Borrowings under the Five Year Revolver due July 2023 and the Five Year Revolver due December 2022 bear interest at the three-month London Interbank Offered Rate (“LIBOR”) rate plus a margin or, in certain instances (including if LIBOR is discontinued), at an alternate interest rate as described in each respective revolver. LIBOR is being discontinued globally, and as such, a new benchmark will take its place. We are in discussion with our Parent to further clarify the reference rate(s) applicable to our revolving credit facilities once LIBOR is discontinued, and once determined, will assess the financial impact, if any.

Our weighted average interest rate for ~~both~~ the ~~three~~six months ended ~~March~~June 3130, 2022 and ~~March~~June 3130, 2021 was 3.12% and 3.0%, respectively. The weighted average interest rate includes drawn and undrawn interest fees, but does not consider the amortization of debt issuance costs or capitalized interest. A 1/8 percentage point (12.5 basis points) increase in the interest rate on the total variable rate debt of $744 million as of ~~March~~June 3130, 2022 would increase our consolidated annual interest expense by approximately $1 million.

We will need to rely on the willingness and ability of our related party lender to secure additional debt, our ability to use cash from operations and/or obtain new debt from other sources to repay/refinance such loans when they come due and/or to secure additional debt as needed.

As of ~~March~~both June 3130, 2022 and December 31, 2021, we were in compliance with the covenants contained in our credit facilities.

For definitions and additional information on our credit facilities, refer to Note 56 – Related Party Debt in the Notes to the Unaudited Consolidated Financial Statements in this report and Note 8 – Related Party Debt in the Notes to the Consolidated Financial Statements included in Part II, Item 8 in our 2021 Annual Report.

Cash Flows from Our Operations

Operating Activities. We generated $~~157~~341 million in cash flow from operating activities in the Current ~~Quarter~~Period compared to $~~166~~351 million in the Comparable ~~Quarter~~Period. The decrease in cash flows was primarily driven by lower undistributed equity earnings from our equity method investments in the Current ~~Quarter~~Period. This decrease was partially offset by the timing of receipt of receivables and deferred revenue, and payment of accruals.

3841

Investing Activities. Our cash flow provided by investing activities was $1434 million in the Current ~~Quarter~~Period compared to $935 million in the Comparable ~~Quarter~~Period. The ~~increase~~decrease in cash flow provided by investing activities was primarily due to a higher ~~return~~capital ofexpenditures ~~investment~~in ~~and~~the ~~lower~~Current ~~contribution~~Period compared to ~~investment~~Comparable Period, and no cash received from any transactions in the Current ~~Quarter~~Period compared to proceeds received from the May 2021 Transaction and the Auger Divestiture in the Comparable ~~Quarter,~~Period. ~~partially~~This is offset by a higher ~~capital~~return ~~expenditures~~of investment and lower contribution to investment in the Current ~~Quarter~~Period compared to the Comparable ~~Quarter~~Period.

Financing Activities. Our cash flow used in financing activities was $~~281~~411 million in the Current ~~Quarter~~Period compared to $~~178~~353 million in the Comparable ~~Quarter~~Period. The increase in cash flow used in financing activities was primarily due to partial repayment of outstanding debt in the Current ~~Quarter~~Period. This increase was partially offset by lower distributions to unitholders and non-controlling interests in the Current ~~Quarter~~Period, as well as the receipt of other contributions from both our Parent and a noncontrolling interest in the Current Period and a prepayment fee paid in the Comparable ~~Quarter~~Period.

Capital Expenditures and Investments

Our operations can be capital intensive, requiring investments to maintain, expand, upgrade or enhance existing operations and to meet environmental and operational regulations. Our capital requirements consist of maintenance capital expenditures and expansion capital expenditures. Examples of maintenance capital expenditures are those made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets and to extend their useful lives, or other capital expenditures that are incurred in maintaining existing system volumes and related cash flows. In contrast, expansion capital expenditures are those made to acquire additional assets to grow our business, to expand and upgrade our systems and facilities and to construct or acquire new systems or facilities. We regularly explore opportunities to improve service to our customers and maintain or increase our assets’ capacity and revenue. We may incur substantial amounts of capital expenditures in certain periods in connection with large maintenance projects that are intended to only maintain our assets’ capacity or revenue.

We incurred capital expenditures and investments of $28 million ~~and $4 million~~ for both the Current ~~Quarter~~Period and the Comparable ~~Quarter, respectively~~Period. The decrease in capital expenditures and investments in the Current Quarter as compared to the Comparable Quarter was primarily due to a decrease in capital contributions for our interest in Permian Basin.

A summary of our capital expenditures and investments is shown in the table below:

	Three Months Ended March 31,
	Three Months Ended June 30,				Six Months Ended June 30,
	2022		2021		2022		2021

Expansion and Maintenance Expenditures

Pecten had no expansion capital expenditures for both the three and six months ended ~~March~~June 3130, 2022, and we expect Pecten’s expansion capital expenditures to be approximately $32 million for the remainder of 2022. These expected expenditures relate to the ~~intended expansion of the Lockport terminal and the~~ potential expansion of the Auger corridor.

Zydeco’s maintenance capital expenditures for the three and six months ended ~~March~~June 3130, 2022 were less than $1 million and $1 million, respectively, primarily for the Houma motor control center upgrade. We expect Zydeco’s maintenance capital expenditures to be approximately $2 million for the remainder of 2022, of which approximately $1 million is related to the Houma tank maintenance projects and $1 million is related to ~~the~~various ~~upgrade~~other ofmaintenance ~~the Houma motor control center~~projects.

Pecten’s maintenance capital expenditures for both the three and six months ended ~~March~~June 3130, 2022 were less than $1 million, and we expect Pecten’s maintenance capital expenditures to be approximately $2 million for the remainder of 2022. These expected expenditures relate to maintenance on the Lockport terminal and the Auger ~~system~~and Delta systems.

Triton’s ~~had no~~ maintenance capital expenditures for both the three and six months ended ~~March~~June 3130, 2022, ~~and~~was we$1 million. We expect Triton’s maintenance capital expenditures to be approximately $23 million for the remainder of 2022, of which approximately $1 million is related to the ~~Seattle~~Des Plaines truck, tank and control center upgrades. The remaining maintenance capital expenditure is related to various other routine maintenance projects.

Odyssey’s maintenance capital expenditures for the three and six months ended ~~March~~June 3130, 2022 were $15 million and $6 million, respectively, related to a project ~~at MP289C~~ to re-route two pipelines around the MP289C platform. We expect Odyssey’s maintenance capital expenditures to be approximately $2923 million for the remainder of 2022 related to this pipeline re-route project.

We do not expect any maintenance capital expenditures for Sand Dollar in 2022.

We anticipate that capital expenditures for the remainder of the year will be funded primarily with cash from operations.

Capital Contributions

In accordance with the Member Interest Purchase Agreement dated October 16, 2017, pursuant to which we acquired a 50% interest in Permian Basin, we will make capital contributions for our pro rata interest in Permian Basin to fund capital and other expenditures, as approved by a supermajority (75%) vote of the members. We did not make any capital contribution in the three and six months ended ~~March~~June 3130, 2022, and expect to make approximately $13 million in capital contributions during the remainder of 2022.

Off-Balance Sheet Arrangements

We have not entered into any transactions, agreements or other contractual arrangements that would result in off-balance sheet liabilities.

Environmental Matters and Compliance Costs

Our operations are subject to extensive and frequently changing federal, state and local laws, regulations and ordinances relating to the protection of the environment. Among other things, these laws and regulations govern the emission or discharge of pollutants into or onto the land, air and water, the handling and disposal of solid and hazardous wastes and the remediation of contamination. As with the industry in general, compliance with existing and anticipated environmental laws and regulations increases our overall cost of business, including our capital costs to construct, maintain, operate and upgrade equipment and facilities. While these laws and regulations affect our maintenance capital expenditures and net income, we believe they do not affect our competitive position, as the operations of our competitors are similarly affected. We believe our facilities are in substantial compliance with applicable environmental laws and regulations. However, these laws and regulations are subject to changes, or to changes in the interpretation of such laws and regulations, by regulatory authorities, and continued and future compliance with such laws and regulations may require us to incur significant expenditures. Additionally, violation of environmental laws, regulations and permits can result in the imposition of significant administrative, civil and criminal penalties, injunctions limiting our operations, investigatory or remedial liabilities or construction bans or delays in the construction of additional facilities or equipment. Additionally, a release of hydrocarbons or hazardous substances into the environment could, to the extent the event is not insured, subject us to substantial expenses, including costs to comply with applicable laws and regulations and to resolve claims by third parties for personal injury or property damage or claims by the U.S. federal government or state governments for natural resources damages. These impacts could directly and indirectly affect our business and have an adverse impact on our financial position, results of operations and liquidity if we do not recover these expenditures through the rates and fees we receive for our services. We believe our competitors must comply with similar environmental laws and regulations. However, the specific impact on each competitor may vary depending on a number of factors, including, but not limited to, the type of competitor and location of its operating facilities. For additional information, refer to Environmental Matters, Items 1 and 2. Business and Properties in our 2021 Annual Report.

We accrue for environmental remediation activities when the responsibility to remediate is probable and the amount of associated costs can be reasonably estimated. As environmental remediation matters proceed toward ultimate resolution or as additional remediation obligations arise, charges in excess of those previously accrued may be required. New or expanded environmental requirements, which could increase our environmental costs, may arise in the future. We believe we substantially comply with all legal requirements regarding the environment; however, as not all of the associated costs are fixed or presently determinable (even under existing legislation) and may be affected by future legislation or regulations, it is not possible to predict all of the ultimate costs of compliance, including remediation costs that may be incurred and penalties that may be imposed.

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are set forth in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operation — Critical Accounting Policies and Estimates in our 2021 Annual Report. As of ~~March~~June 3130, 2022, there have been no significant changes to our critical accounting policies and estimates since our 2021 Annual Report was filed.

You can identify our forward-looking statements by the words “anticipate,” “estimate,” “believe,” “budget,” “continue,” “could,” “intend,” “may,” “plan,” “potential,” “predict,” “seek,” “should,” “would,” “expect,” “objective,” “projection,” “forecast,” “goal,” “guidance,” “outlook,” “effort,” “target” and similar expressions.

We based the forward-looking statements on our current expectations, estimates and projections about us and the industries in which we operate in general. We caution you these statements are not guarantees of future performance as they involve assumptions that, while made in good faith, may prove to be incorrect, and involve risks and uncertainties we cannot predict. In addition, we based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. Accordingly, our actual outcomes and results may differ materially from what we have expressed in the forward-looking statements. Any differences could result from a variety of factors, including the following:

•~~The~~Whether ~~outcome of~~ the ~~non-binding,~~proposed ~~preliminary~~Transaction ~~proposal made by SPLC~~ to acquire all of our issued and outstanding common units not already owned by SPLC or its affiliates will be consummated in 2022 or at all.

•The proposed Transaction includes risks that it may not be consummated or the benefits contemplated therefrom may not be realized, including the ability to obtain the requisite regulatory approval and the satisfaction of the other conditions to the consummation of the proposed Transaction, and the potential impact of the announcement or consummation of the proposed Transaction on relationships, including with employees, suppliers, customers, competitors and credit rating agencies.

•The continued ability of Shell and our non-affiliate customers to satisfy their obligations under our commercial and other agreements.

•The volume of crude oil, refined petroleum products and refinery gas we transport or store and the prices that we can charge our customers.

•The tariff rates with respect to volumes that we transport through our regulated assets, which rates are subject to review and possible adjustment imposed by federal and state regulators.

•Changes in revenue we realize under the loss allowance provisions of our fees and tariffs resulting from changes in underlying commodity prices.

•Our ability to renew or replace our third-party contract portfolio on comparable terms.

•Fluctuations in the prices for crude oil, refined petroleum products and refinery gas, including fluctuations due to political or economic measures taken by various countries.

•The level of production of refinery gas by refineries and demand by chemical sites.

•The level of onshore and offshore (including deepwater) production and demand for crude oil by U.S. refiners.

•Changes in global economic conditions and the effects of a global economic downturn on the business of Shell and the business of its suppliers, customers, business partners and credit lenders.

•The ongoing COVID-19 pandemic and related governmental regulations and travel restrictions (including our vaccine mandate for offshore employees), and any resulting reduction in the global demand for oil and natural gas.

•Availability of acquisitions and financing for acquisitions on our expected timing and acceptable terms.

•Changes in, and availability to us, of the equity and debt capital markets.

•Liabilities associated with the risks and operational hazards inherent in transporting and/or storing crude oil, refined petroleum products and refinery gas.

•Curtailment of operations or expansion projects due to unexpected leaks, spills or severe weather disruption, including disruptions caused by hurricanes; riots, strikes, lockouts or other industrial disturbances; or failure of information technology systems due to various causes, including unauthorized access or attack.

•Costs or liabilities associated with federal, state and local laws and regulations, including those that may be implemented by the current U.S. presidential administration, relating to environmental protection and safety, including spills, releases and pipeline integrity.

•Costs associated with compliance with evolving environmental laws and regulations on climate change.

•Costs associated with compliance with safety regulations and system maintenance programs, including pipeline integrity management program testing and related repairs.

•Changes in tax status or applicable tax laws.

•Changes in the cost or availability of third-party vessels, pipelines, rail cars and other means of delivering and transporting crude oil, refined petroleum products and refinery gas.

•Direct or indirect effects on our business resulting from actual or threatened terrorist incidents or acts of war, including the ongoing Russian invasion of Ukraine, its associated impacts on global commodity markets and the resulting political and economic sanctions on Russia.

•The effect of releases from the U.S. Strategic Petroleum Reserve.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of loss arising from adverse changes in market rates and prices. The information about market risks for the ~~three~~six months ended ~~March~~June 3130, 2022 does not differ materially from that disclosed in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations— – Quantitative and Qualitative Disclosures About Market Risk” in our 2021 Annual Report, except as noted below.

Commodity Price Risk

With the exception of buy/sell arrangements on some of our offshore pipelines and our allowance oil retained, we do not take ownership of the crude oil or refined products that we transport and store for our customers, and we do not engage in the trading of any commodities. We therefore have limited direct exposure to risks associated with fluctuating commodity prices.

Our long-term transportation agreements and tariffs for crude oil shipments include pipeline loss allowance (“PLA”). The PLA provides additional revenue for us at a stated factor per barrel. If product losses on our pipelines are within the allowed levels, we retain the benefit; otherwise, we are required to compensate our customers for any product losses that exceed the allowed levels. We take title to any excess product that we transport when product losses are within the allowed level, and we sell that product several times per year at prevailing market prices. This allowance oil revenue, which accounted for approximately 87% and 56%, respectively, of our total revenue for the ~~three~~six months ended ~~March~~June 3130, 2022 and ~~March~~June 3130, 2021, is subject to more volatility than transportation revenue, as it is directly dependent on our measurement capability and commodity prices. As a result, the income we realize under our loss allowance provisions will increase or decrease as a result of changes in the mix of product transported, measurement accuracy and underlying commodity prices. We do not intend to enter into any hedging agreements to mitigate our exposure to decreases in commodity prices through our loss allowances.

Interest Rate Risk

We are exposed to the risk of changes in interest rates, primarily as a result of variable rate borrowings under our revolving credit facilities. To the extent that interest rates increase, interest expense for these revolving credit facilities will also increase. As of ~~March~~June 3130, 2022 and December 31, 2021, the Partnership had $744 million and $894 million, respectively, in outstanding variable rate borrowings under these revolving credit facilities. A hypothetical change of 12.5 basis points in the interest rate of our variable rate debt would impact the Partnership’s annual interest expense by approximately $1 million for both the ~~three~~six months ended ~~March~~June 3130, 2022 and ~~March~~June 3130, 2021. We do not currently intend to enter into any interest rate hedging agreements, but will continue to monitor our interest rate exposure.

Our fixed rate debt does not expose us to fluctuations in our results of operations or liquidity from changes in market interest rates. Changes in interest rates do affect the fair value of our fixed rate debt. See Note 56 – Related Party Debt in the Notes to the Unaudited Consolidated Financial Statements in this report for further discussion of our borrowings and fair value measurements.

Other Market Risks

We may also have risk associated with changes in policy or other actions taken by the FERC. Refer to Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Factors Affecting Our Business and Outlook – Regulation for additional information.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Our disclosure controls and procedures have been designed to provide reasonable assurance that the information required to be disclosed in the reports we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures. Based on management’s evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective at the reasonable assurance level as of ~~March~~June 3130, 2022.

4347

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended ~~March~~June 3130, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

4448

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Although we may, from time to time, be involved in litigation and claims arising out of our operations in the ordinary course of business, we are not a party to any litigation or governmental or other proceeding that we believe will have a material adverse impact on our financial position, results of operations or cash flows.

Information regarding legal proceedings is set forth in Note 1112 – Commitments and Contingencies in the Notes to the Unaudited Consolidated Financial Statements in this report and is incorporated herein by reference.

Item 1A. Risk Factors

Risk factors relating to us are discussed in Part I, Item 1A. Risk Factors in our 2021 Annual Report. ~~There~~Except as set forth below, there have been no material changes from the risk factors previously disclosed in our 2021 Annual Report.

45The Transaction may not be consummated, which may cause the market price of our common units to decline.

The Merger Agreement contains conditions, some of which are beyond the parties’ control, such as the absence of injunctions or rulings prohibiting consummation of the Transaction, that, if not satisfied or waived, may prevent, delay or otherwise result in the Transaction not occurring, even though Holdings delivered its written consent approving the Transaction. We cannot predict with certainty whether and when any of the conditions to the completion of the Transaction will be satisfied. If the Transaction does not occur, the market price of our common units may decline.

If the Transaction with SUSA does not close, we will not benefit from the expenses we have incurred in the pursuit of the Transaction.

The Transaction with SUSA may not be completed. If the Transaction is not completed, we will have incurred substantial expenses for which no ultimate benefit will have been received by us. We currently expect to incur merger-related expenses consisting of independent advisory, legal and accounting fees, and financial printing and other related charges, much of which may be incurred even if the Transaction is not completed. In addition, we may be liable to SUSA for fees or expenses up to $5 million under the terms and conditions of the Merger Agreement.

We may be subject to lawsuits relating to the Transaction, which could materially adversely affect our operations and

financial condition or prevent or delay completion of the Transaction.

The directors and officers of our general partner may be subject to lawsuits relating to the Merger. Such litigation is common in connection with acquisitions of public companies, regardless of any merits related to the underlying acquisition. While we will evaluate and defend against any actions vigorously, the costs of the defense of such lawsuits and other effects of such litigation could have an adverse effect on our operations and financial condition. In addition, the attention of our management may be diverted to the Transaction and related lawsuits rather than our own operations and pursuit of other opportunities that could have been beneficial to us.

If any lawsuit is filed challenging the Transaction and is successful in obtaining an injunction preventing the parties to the Merger Agreement from consummating the Transaction, such injunction may prevent the Transaction from being completed in the expected timeframe, or at all.

Failure to complete, or significant delays in completing, the Transaction with SUSA could negatively affect the trading price of our common units and our future business and financial results.

The Transaction with SUSA is a taxable transaction and the resulting tax liability of our common unitholders, if any, will

depend on each such common unitholder’s particular situation.

The receipt of cash as merger consideration in exchange for our publicly traded common units in the Transaction will be treated as a taxable sale by such common unitholders for U.S. federal income tax purposes. The amount of ordinary income and capital gain or loss recognized by each common unitholder in the Transaction will vary depending on each common unitholder’s particular situation, including the amount of cash received by the common unitholder as consideration in the Transaction, the adjusted tax basis of the common units exchanged by the common unitholder in the Transaction, the amount of depreciation and amortization deductions previously allocated to the common unitholder and the amount of any suspended passive losses that may be available to the common unitholder in respect of its common units to offset a portion of any gain recognized by the common unitholder.

While the Merger Agreement with SUSA is in effect, we may be limited in our ability to pursue other attractive business opportunities.

SUSA is interested only in acquiring our publicly traded common units and is not interested in selling the common units or general partner interest in us that it owns. Therefore, even if a proposal or offer to acquire our assets or equity interests were to materialize, SUSA, which indirectly owns approximately 68.5 percent of our common units, and has a majority position on the board of directors of our general partner, would likely decide not to vote or tender its common units or general partner interest in favor of any such transaction and recommend against approval of such transactions by our common unitholders. We have also agreed to refrain from taking certain actions with respect to our business and financial affairs pending completion of the Transaction or termination of the Merger Agreement. These restrictions could be in effect for an extended period of time if completion of the Transaction is delayed.

In addition to the economic costs associated with pursuing a merger, our management continues to devote substantial time and other resources to the proposed Transaction and related matters, which could limit our ability to pursue other attractive business opportunities, including potential joint ventures, standalone projects and other transactions. If we are unable to pursue such other attractive business opportunities, our growth prospects and the long-term strategic position of our business could be adversely affected.

Item 5. Other Information

Disclosures Required Pursuant to Section 13(r) of the Securities Exchange Act of 1934

In accordance with our General Business Principles and Code of Conduct, Shell Midstream Partners, L.P. seeks to comply with all applicable international trade laws, including applicable sanctions and embargoes.

Under the Iran Threat Reduction and Syria Human Rights Act of 2012, and Section 13(r) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we are required to include certain disclosures in our periodic reports if we or any of our “affiliates” (as defined in Rule 12b-2 under the Exchange Act) knowingly engaged in certain specified activities during the period covered by the report. Because the U.S. Securities and Exchange Commission defines the term “affiliate” broadly, it includes any entity controlled by us as well as any person or entity that controls us or is under common control with us.

The activities listed below have been conducted outside the United States by non-U.S. affiliates of Shell plc that may be deemed to be under common control with us. The disclosure does not relate to any activities conducted directly by us, our subsidiaries or our general partner and does not involve our or our general partner’s management.

For purposes of this disclosure, we refer to Shell plc and its subsidiaries, other than us, our subsidiaries, our general partner and Shell Midstream LP Holdings LLC, as the “Shell Group.” When not specifically identified, references to actions taken by the Shell Group mean actions taken by the applicable Shell Group company. None of the payments disclosed below were made in U.S. dollars, nor are any of the balances disclosed below held in U.S. dollars; however, for disclosure purposes, all have been converted into U.S. dollars at the appropriate exchange rate. We do not believe that any of the transactions or activities listed below violated U.S. sanctions.

The Shell Group maintains accounts with Karafarin Bank where its cash deposits (balance of $5,~~640~~471,~~775~~211 at ~~March~~June 3130, 2022) generated non-taxable interest income of $6367,~~328,~~493 ~~and it paid $2 for bank charges,~~ in ~~each case in~~ the ~~first~~second quarter of 2022. As the accounts with Karafarin Bank will be maintained by the Shell Group for the foreseeable future, we expect that the receipt of non-taxable interest income and the payment of bank charges by the Shell Group to continue in the future.
