Note 1.  Partnership Organization and Operations

We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “EPD.”  Our preferred units are not publicly traded.  We were formed in April 1998 to own and operate certain natural gas liquids (“NGLs”) related businesses of EPCO and are a leading North American provider of midstream energy services to producers and consumers of natural gas, NGLs, crude oil, petrochemicals and refined products.  We are owned by our limited partners (preferred and common unitholders) from an economic perspective.  Enterprise GP, which owns a non-economic general partner interest in us, manages our Partnership.  We conduct substantially all of our business operations through EPO and its consolidated subsidiaries.

Our fully integrated, midstream energy asset network (or “value chain”) links producers of natural gas, NGLs and crude oil from some of the largest supply basins in the United States (“U.S.”), Canada and the Gulf of Mexico with domestic consumers and international markets.  Our midstream energy operations include:

•
natural gas gathering, treating, processing, transportation and storage;

•
NGL transportation, fractionation, storage, and marine terminals (including those used to export liquefied petroleum gases (“LPG”) and ethane);

•
crude oil gathering, transportation, storage, and marine terminals;

•
propylene production facilities (including propane dehydrogenation (“PDH”) facilities), butane isomerization, octane enhancement, isobutane dehydrogenation (“iBDH”) and high purity isobutylene (“HPIB”) production facilities;

•
petrochemical and refined products transportation, storage, and marine terminals (including those used to export ethylene and polymer grade propylene (“PGP”)); and

•
a marine transportation business that operates on key U.S. inland and intracoastal waterway systems. 

Like many publicly traded partnerships, we have no employees.  All of our management, administrative and operating functions are performed by employees of EPCO pursuant to an administrative services agreement (the “ASA”) or by other service providers.  See Note 14 for information regarding related party matters.

Our results of operations for the six months ended June 30, 2024 are not necessarily indicative of results expected for the full year of 2024.  In our opinion, the accompanying Unaudited Condensed Consolidated Financial Statements include all adjustments consisting of normal recurring accruals necessary for fair presentation.  Although we believe the disclosures in these financial statements are adequate and make the information presented not misleading, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).

These Unaudited Condensed Consolidated Financial Statements and Notes thereto should be read in conjunction with the Audited Consolidated Financial Statements and Notes thereto included in our annual report on Form 10-K for the year ended December 31, 2023  (the “2023 Form 10-K”) filed with the SEC on February 28, 2024.

Plants, pipelines and facilities include distillation-based and reaction-based plants; NGL, natural gas, crude oil and petrochemical and refined products pipelines; terminal loading and unloading facilities; buildings; office furniture and equipment; laboratory and shop equipment and related assets.
(2)
Underground and other storage facilities include underground product storage caverns; above ground storage tanks; water wells and related assets.
(3)
Transportation equipment includes tractor-trailer tank trucks and other vehicles and similar assets used in our operations.
(4)
Marine vessels include tow boats, barges and related equipment used in our marine transportation business.
(5)
In general, the estimated useful lives of major assets within this category are: distillation-based and reaction-based plants, 20-35 years; pipelines and related equipment, 5-45 years; terminal facilities, 10-35 years; buildings, 20-40 years; office furniture and equipment, 3-20 years; and laboratory and shop equipment, 5-35 years.
(6)
In general, the estimated useful lives of assets within this category are: underground storage facilities, 5-35 years; storage tanks, 10-40 years; and water wells, 5-35 years.
(7)
For reaction-based plants, we use the deferral method when accounting for major maintenance activities.  Under the deferral method, major maintenance costs are capitalized and amortized over the period until the next major overhaul project.  On a weighted-average basis, the expected remaining amortization period for these costs is 3.7 years.

Property, plant and equipment at June 30, 2024 and December 31, 2023 includes $134 million and $109 million, respectively, of asset retirement costs capitalized as an increase in the associated long-lived asset.

The following table presents information regarding our asset retirement obligations, or AROs, since December 31, 2023:

(1)
Depreciation expense is a component of “Costs and expenses” as presented on our Unaudited Condensed Statements of Consolidated Operations.
(2)
We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase.  The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset’s estimated useful life as a component of depreciation expense.  When capitalized interest is recorded, it reduces interest expense from what it would be otherwise.

March 2024 $1.5 Billion 364-Day Revolving Credit Agreement

In March 2024, EPO entered into a new 364-Day Revolving Credit Agreement (the “March 2024 $1.5 Billion 364-Day Revolving Credit Agreement”) that replaced its prior 364-day revolving credit agreement.  There were no principal amounts outstanding under the prior 364-day revolving credit agreement when it was replaced by the March 2024 $1.5 Billion 364-Day Revolving Credit Agreement.  As of June 30, 2024, there were no principal amounts outstanding under the March 2024 $1.5 Billion 364-Day Revolving Credit Agreement.

Under the terms of the March 2024 $1.5 Billion 364-Day Revolving Credit Agreement, EPO may borrow up to $1.5 billion (which may be increased by up to $200 million to $1.7 billion at EPO’s election, provided certain conditions are met) at a variable interest rate for a term of up to 364 days, subject to the terms and conditions set forth therein.  The March 2024 $1.5 Billion 364-Day Revolving Credit Agreement matures in March 2025.  To the extent that principal amounts are outstanding at the maturity date, EPO may elect to have the entire principal balance then outstanding continued as non-revolving term loans for a period of one additional year, payable in March 2026.  Borrowings under the March 2024 $1.5 Billion 364-Day Revolving Credit Agreement may be used for working capital, capital expenditures, acquisitions and general company purposes.

The March 2024 $1.5 Billion 364-Day Revolving Credit Agreement contains customary representations, warranties, covenants (affirmative and negative) and events of default, the occurrence of which would permit the lenders to accelerate the maturity date of any amounts borrowed under this credit agreement.  The March 2024 $1.5 Billion 364-Day Revolving Credit Agreement also restricts EPO’s ability to pay cash distributions to the Partnership, if an event of default (as defined in the credit agreement) has occurred and is continuing at the time such distribution is scheduled to be paid or would result therefrom.

EPO’s obligations under the March 2024 $1.5 Billion 364-Day Revolving Credit Agreement are not secured by any collateral; however, they are guaranteed by the Partnership.

Issuance of $2.0 Billion of Senior Notes in January 2024

In January 2024, EPO issued $2.0 billion aggregate principal amount of senior notes comprised of (i) $1.0 billion principal amount of senior notes due January 2027 (“Senior Notes HHH”) and (ii) $1.0 billion principal amount of senior notes due January 2034 (“Senior Notes III”).  Net proceeds from this offering were used by EPO for general company purposes, including for growth capital investments, and the repayment of debt (including the repayment of all of our $850 million principal amount of 3.90% Senior Notes JJ at their maturity in February 2024 and amounts outstanding under our commercial paper program).

Senior Notes HHH were issued at 99.897% of their principal amount and have a fixed interest rate of 4.60% per year.  Senior Notes III were issued at 99.705% of their principal amount and have a fixed interest rate of 4.85% per year.  The Partnership guaranteed these senior notes through an unconditional guarantee on an unsecured and unsubordinated basis.

Letters of Credit

At June 30, 2024, EPO had $22 million of letters of credit outstanding primarily related to our insurance program.

Lender Financial Covenants

We were in compliance with the financial covenants of our consolidated debt agreements at June 30, 2024.

Parent-Subsidiary Guarantor Relationships

The Partnership acts as guarantor of the consolidated debt obligations of EPO, with the exception of the remaining debt obligations of TEPPCO.  If EPO were to default on any of its guaranteed debt, the Partnership would be responsible for full and unconditional repayment of such obligations.

Registration Statements
We have a universal shelf registration statement on file with the SEC which allows the Partnership and EPO (each on a standalone basis) to issue an unlimited amount of equity and debt securities, respectively.

In addition, the Partnership has a registration statement on file with the SEC covering the issuance of up to $2.5 billion of its common units in amounts, at prices and on terms based on market conditions and other factors at the time of such offerings (referred to as the Partnership’s at-the-market (“ATM”) program).  The Partnership did not issue any common units under its ATM program during the six months ended June 30, 2024.  The Partnership’s capacity to issue additional common units under the ATM program remains at $2.5 billion as of June 30, 2024.

We may issue additional equity and debt securities to assist us in meeting our future liquidity requirements, including those related to capital investments.

Common Unit Repurchases Under 2019 Buyback Program
In January 2019, we announced that the Board had approved a $2.0 billion multi-year unit buyback program (the “2019 Buyback Program”), which provides the Partnership with an additional method to return capital to investors.  The 2019 Buyback Program authorizes the Partnership to repurchase its common units from time to time, including through open market purchases and negotiated transactions.  No time limit has been set for completion of the program, and it may be suspended or discontinued at any time.

During the three and six months ended June 30, 2024, the Partnership repurchased 1,419,581 and 2,806,416 common units, respectively, under the 2019 Buyback Program through open market purchases.  The total cost of these repurchases, including commissions and fees, was $40 million and $80 million, respectively.  During the three and six months ended June 30, 2023, the Partnership repurchased 2,910,121 and 3,592,710 common units, respectively, under the 2019 Buyback Program through open market purchases.  The total cost of these repurchases, including commissions and fees, was $75 million and $92 million, respectively.  Common units repurchased under the 2019 Buyback Program are immediately cancelled upon acquisition.  At June 30, 2024, the remaining available capacity under the 2019 Buyback Program was $1.0 billion.

Common Units Issued in Connection With the Vesting of Phantom Unit Awards
After taking into account tax withholding requirements, the Partnership issued 4,842,244 new common units to employees in connection with the vesting of phantom unit awards during the six months ended June 30, 2024.  See Note 12 for information regarding our phantom unit awards.

Common Units Delivered Under DRIP and EUPP
The Partnership has registration statements on file with the SEC in connection with its distribution reinvestment plan (“DRIP”) and employee unit purchase plan (“EUPP”).  In July 2019, the Partnership announced that, beginning with the quarterly distribution payment paid in August 2019, it would use common units purchased on the open market, rather than issuing new common units, to satisfy its delivery obligations under the DRIP and EUPP.  This election is subject to change in future quarters depending on the Partnership’s need for equity capital.

During the six months ended June 30, 2024, agents of the Partnership purchased 3,364,678 common units on the open market and delivered them to participants in the DRIP and EUPP.  Apart from $2 million attributable to the plan discount available to all participants in the EUPP, the funds used to effect these purchases were sourced from the DRIP and EUPP participants.  No other Partnership funds were used to satisfy these obligations.  We plan to use open market purchases to satisfy DRIP and EUPP reinvestments in connection with the distribution expected to be paid on August 14, 2024.

Preferred Units

The following table summarizes changes in the number of our Series A Cumulative Convertible Preferred Units (“preferred units”) outstanding since December 31, 2023.

Preferred units outstanding at December 31, 2023 and March 31, 2024
    
50,412

Preferred units outstanding at June 30, 2024

We present the capital accounts attributable to our preferred unitholders as mezzanine equity on our consolidated balance sheets since the terms of the preferred units allow for cash redemption by such unitholders in the event of a Change of Control (as defined in our partnership agreement), without regard to the likelihood of such an event.

During the six months ended June 30, 2024, the Partnership made quarterly cash distributions to its preferred unitholders of $2 million and paid-in-kind distributions of 90 new preferred units valued at less than $1 million.

Noncontrolling Interests

On February 16, 2024, we acquired the remaining 20% equity interest in Whitethorn Pipeline Company LLC (“Whitethorn”) and remaining 25% equity interest in Enterprise EF78 LLC (“EF78”) from affiliates of Western Midstream Partners, LP (“Western Midstream”) for total cash consideration of $375 million.  We funded the cash consideration using cash on hand and proceeds from the issuance of short-term notes under our commercial paper program.  As a result of these transactions, Whitethorn and EF78 are now our wholly owned subsidiaries. 

Additionally, on March 27, 2024, we acquired an additional 15% equity interest in Panola Pipeline Company, LLC (“Panola”) from an affiliate of Western Midstream for $25 million in cash consideration.  We funded the cash consideration using cash on hand.  As a result of this transaction, our equity interest in Panola increased to 70%.

Since we had a controlling interest in each of these entities before and after the acquisitions, the increase in our ownership interest in each entity was accounted for as an equity transaction with no gain or loss recognized.

Cash Distributions

On July 10, 2024, we announced that the Board declared a quarterly cash distribution of $0.525 per common unit, or $2.10 per common unit on an annualized basis, to be paid to the Partnership’s common unitholders with respect to the second quarter of 2024.  The quarterly distribution is payable on August 14, 2024 to unitholders of record as of the close of business on July 31, 2024.  The total amount to be paid is $1.15 billion, which includes $11 million for distribution equivalent rights (“DERs”) on phantom unit awards.

The payment of quarterly cash distributions is subject to management’s evaluation of our financial condition, results of operations and cash flows in connection with such payments and Board approval.  Management will evaluate any future increases in cash distributions on a quarterly basis. 


Note 9.  Revenues

We classify our revenues into sales of products and midstream services.  Product sales relate primarily to our various marketing activities whereas midstream services represent our other integrated businesses (i.e., gathering, processing, transportation, fractionation, storage and terminaling).  The following table presents our revenues by business segment, and further by revenue type, for the periods indicated:

Unbilled revenues are transferred to accounts receivable once we have an unconditional right to consideration from the customer.  Deferred revenues are recognized as revenue upon satisfaction of our performance obligation to the customer.
(2)
Unbilled revenue represents revenue that has been recognized upon satisfaction of a performance obligation, but cannot be contractually invoiced (or billed) to the customer at the balance sheet date until a future period.  Deferred revenue is recorded when payment is received from a customer prior to our satisfaction of the associated performance obligation.

Remaining Performance Obligations

The following table presents estimated fixed future consideration from revenue contracts that contain minimum volume commitments, deficiency and similar fees and the term of the contracts exceeds one year.  These amounts represent the revenues we expect to recognize in future periods from these contracts as of June 30, 2024.

Note 10.  Business Segments and Related Information

Our operations are reported under four business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services and (iv) Petrochemical & Refined Products Services.  Our business segments are generally organized and managed according to the types of services rendered (or technologies employed) and products produced and/or sold.  

Financial information regarding these segments is evaluated regularly by our co-chief operating decision makers in deciding how to allocate resources and in assessing our operating and financial performance.  The co-principal executive officers of our general partner have been identified as our co-chief operating decision makers.  While these two officers evaluate results in a number of different ways, the business segment structure is the primary basis for which the allocation of resources and financial results are assessed.

The following information summarizes the assets and operations of each business segment:

•
Our NGL Pipelines & Services business segment includes our natural gas processing and related NGL marketing activities, NGL pipelines, NGL fractionation facilities, NGL and related product storage facilities, and NGL marine terminals.

•
Our Crude Oil Pipelines & Services business segment includes our crude oil pipelines, crude oil storage and marine terminals, and related crude oil marketing activities.  

•
Our Natural Gas Pipelines & Services business segment includes our natural gas pipeline systems that provide for the gathering, treating and transportation of natural gas.  This segment also includes our natural gas marketing activities.

•
Our Petrochemical & Refined Products Services business segment includes our (i) propylene production facilities, which include propylene fractionation units and PDH facilities, and related pipelines and marketing activities, (ii) butane isomerization complex and related deisobutanizer operations, (iii) octane enhancement, iBDH and HPIB production facilities, (iv) refined products pipelines, terminals and related marketing activities, (v) ethylene export terminal and related operations; and (vi) marine transportation business.

Our plants, pipelines and other fixed assets are located in the U.S.

Segment Gross Operating Margin

We evaluate segment performance based on our financial measure of gross operating margin.  Gross operating margin is an important performance measure of the core profitability of our operations and forms the basis of our internal financial reporting.  We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results.  Gross operating margin is exclusive of other income and expense transactions, income taxes, the cumulative effect of changes in accounting principles and extraordinary charges.  Gross operating margin is presented on a 100% basis before any allocation of earnings to noncontrolling interests. Our calculation of gross operating margin may or may not be comparable to similarly titled measures used by other companies.

(1)
Excludes amortization of major maintenance costs for reaction-based plants, which are a component of gross operating margin.
(2)
Since make-up rights entail a future performance obligation by the pipeline to the shipper, these receipts are recorded as deferred revenue for GAAP purposes; however, these receipts are included in gross operating margin in the period of receipt since they are nonrefundable to the shipper.
(3)
As deferred revenues attributable to make-up rights are subsequently recognized as revenue under GAAP, gross operating margin must be adjusted to remove such amounts to prevent duplication since the associated non-refundable payments were previously included in gross operating margin.

Gross operating margin by segment is calculated by subtracting segment operating costs and expenses from segment revenues, with both segment totals reflecting the adjustments noted in the preceding table, as applicable, and before the elimination of intercompany transactions.  The following table presents gross operating margin by segment for the periods indicated:

Represents the cost of operating our plants, pipelines and other fixed assets excluding: depreciation, amortization and accretion; asset impairment charges; and net losses (gains) attributable to asset sales and related matters.

Fluctuations in our product sales revenues and cost of sales amounts are explained in large part by changes in energy commodity prices.  In general, higher energy commodity prices result in an increase in our revenues attributable to product sales; however, these higher commodity prices would also be expected to increase the associated cost of sales as purchase costs are higher.  The same type of relationship would be true in the case of lower energy commodity sales prices and purchase costs.

Phantom Unit Awards

Subject to customary forfeiture provisions, phantom unit awards allow recipients to acquire the Partnership’s common units once a defined vesting period expires (at no cost to the recipient apart from fulfilling required service and other conditions).  The following table presents phantom unit award activity for the period indicated:

Determined by dividing the aggregate grant date fair value of awards (before an allowance for forfeitures) by the number of awards issued.
(2)
The aggregate grant date fair value of phantom unit awards issued during 2024 was $233 million based on a grant date market price of the Partnership’s common units ranging from $26.25 to $28.05 per unit.  An estimated annual forfeiture rate of 2.0% was applied to these awards.

Each phantom unit award includes a DER, which entitles the participant to nonforfeitable cash payments equal to the product of the number of phantom unit awards outstanding for the participant and the cash distribution per common unit paid by the Partnership to its common unitholders.  Cash payments made in connection with DERs are charged to partners’ equity when the phantom unit award is expected to result in the issuance of common units; otherwise, such amounts are expensed.

For the EPCO group of companies, the unrecognized compensation cost associated with phantom unit awards was $295 million at June 30, 2024, of which our share of such cost is currently estimated to be $241 million.  Due to the graded vesting provisions of these awards, we expect to recognize our share of the unrecognized compensation cost for these awards over a weighted-average period of 2.2 years.

Profits Interest Awards

As of January 1, 2024, EPCO had two limited partnerships (referred to as “Employee Partnerships”) that served as long-term incentive arrangements for key employees of EPCO by providing them profits interest awards (or Class B limited partner interests) in one or more of the Employee Partnerships.

The Class B limited partner interests of these two Employee Partnerships vested on March 26, 2024 when the closing market price of the Partnership’s common units exceeded $29.02 per unit.  As a result of these vesting events, we recognized an incremental $7 million of non-cash compensation expense in the three months ended March 31, 2024.

Note 13.  Hedging Activities and Fair Value Measurements

In the normal course of our business operations, we are exposed to certain risks, including changes in interest rates and commodity prices.  In order to manage risks associated with assets, liabilities and certain anticipated future transactions, we use derivative instruments such as futures, forward contracts, swaps, options and other instruments with similar characteristics.  Substantially all of our derivatives are used for non-trading activities.

Interest Rate Hedging Activities

We may utilize interest rate swaps, forward-starting swaps, options to enter into forward-starting swaps (“swaptions”), and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements.  This strategy may be used in controlling our overall cost of capital associated with such borrowings.

Treasury Locks
A treasury lock is an agreement that fixes the price (or yield) of a specified U.S. treasury security for an established period of time.  We use treasury lock agreements to hedge our exposure to interest rate changes and to reduce the volatility of financing costs on an expected future debt issuance.  During the fourth quarter of 2023, we entered into three treasury lock transactions to fix the ten-year treasury rate at a weighted-average rate of approximately 4.48% on an aggregate notional amount of $600 million.  In January 2024, we entered into two additional treasury lock transactions to fix the ten-year treasury rate at 3.97% on a notional amount of $400 million and to fix the three-year treasury rate at 4.11% on a notional amount of $750 million.  The purpose of these transactions was to hedge the underlying interest rate risk associated with debt issuances that occurred in January 2024 (see Note 7).  In January 2024, we terminated all of the treasury lock transactions simultaneously with our issuance of the three-year and ten-year notes and made total cash payments of $29 million.  As cash flow hedges, losses on these derivative instruments are reflected as a component of accumulated other comprehensive income and will be amortized to earnings as a component of interest expense over the full term of each issuance.

Commodity Hedging Activities

The prices of natural gas, NGLs, crude oil, petrochemicals and refined products, and power are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control.  In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps and basis swaps.

At June 30, 2024, our predominant commodity hedging strategies consisted of (i) hedging anticipated future purchases and sales of commodity products associated with transportation, storage and blending activities, (ii) hedging natural gas processing margins, (iii) hedging the fair value of commodity products held in inventory and (iv) hedging anticipated future purchases of power for certain operations in Southeast Texas.  

•
The objective of our anticipated future commodity purchases and sales hedging program is to hedge the margins of certain transportation, storage, blending and operational activities by locking in purchase and sale prices through the use of derivative instruments and related contracts.

•
The objective of our natural gas processing hedging program is to hedge an amount of earnings associated with these activities. We achieve this objective by executing fixed-price sales for a portion of our expected equity production using derivative instruments and related contracts. For certain natural gas processing contracts, the hedging of expected equity NGL production also involves the purchase of natural gas for plant thermal reduction, which is hedged using derivative instruments and related contracts.

•
The objective of our inventory hedging program is to hedge the fair value of commodity products currently held in inventory by locking in the sales price of the inventory through the use of derivative instruments and related contracts.

•
The objective of our commercial energy hedging program is to hedge anticipated future purchases of power for certain operations in Southeast Texas by locking in purchase prices through the use of derivative instruments and related contracts.

Derivative assets and liabilities recorded on our Unaudited Condensed Consolidated Balance Sheets are presented on a gross-basis and determined at the individual transaction level.  The tabular presentation above provides a means for comparing the gross amount of derivative assets and liabilities, excluding associated accounts payable and receivable, to the net amount that would likely be receivable or payable under a default scenario based on the existence of rights of offset in the respective derivative agreements.  Any cash collateral paid or received is reflected in these tables, but only to the extent that it represents variation margins.  Any amounts associated with derivative prepayments or initial margins that are not influenced by the derivative asset or liability amounts or those that are determined solely on their volumetric notional amounts are excluded from these tables.

Fair Value Measurements

The following tables set forth, by level within the Level 1, 2 and 3 fair value hierarchy, the carrying values of our financial assets and liabilities at the dates indicated.  These assets and liabilities are measured on a recurring basis and are classified based on the lowest level of input used to estimate their fair value.  Our assessment of the relative significance of such inputs requires judgment.

The values for commodity derivatives are presented before and after the application of CME Rule 814, which deems that financial instruments cleared by the CME are settled daily in connection with variation margin payments.  As a result of this exchange rule, CME-related derivatives are considered to have no fair value at the balance sheet date for financial reporting purposes; however, the derivatives remain outstanding and subject to future commodity price fluctuations until they are settled in accordance with their contractual terms.  Derivative transactions cleared on exchanges other than the CME (e.g., the Intercontinental Exchange or ICE) continue to be reported on a gross basis.

Other Fair Value Information

The carrying amounts of cash and cash equivalents (including restricted cash balances), accounts receivable, commercial paper notes and accounts payable approximate their fair values based on their short-term nature.  The estimated total fair value of our fixed-rate debt obligations was $26.5 billion and $26.7 billion at June 30, 2024 and December 31, 2023, respectively.  The aggregate carrying value of these debt obligations was $29.1 billion and $28.0 billion at June 30, 2024 and December 31, 2023, respectively.  These values are primarily based on quoted market prices for such debt or debt of similar terms and maturities (Level 2) and our credit standing.  Changes in market rates of interest affect the fair value of our fixed-rate debt.  The carrying values of our variable-rate long-term debt obligations approximate their fair values since the associated interest rates are market-based.  We do not have any long-term investments in debt or equity securities recorded at fair value.

We believe that the terms and provisions of our related party agreements are fair to us; however, such agreements and transactions may not be as favorable to us as we could have obtained from unaffiliated third parties.

Relationship with EPCO and Affiliates

We have an extensive and ongoing relationship with EPCO and its privately held affiliates (including Enterprise GP, our general partner), which are not a part of our consolidated group of companies.  

At June 30, 2024, EPCO and its privately held affiliates (including Dan Duncan LLC and certain Duncan family trusts) beneficially owned the following limited partner interests in us:

ENTERPRISE PRODUCTS PARTNERS L.P.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
Of the total number of Partnership common units held by EPCO and its privately held affiliates, 62,976,464 have been pledged as security under the separate credit facilities of EPCO and its privately held affiliates at June 30, 2024.  These credit facilities contain customary and other events of default, including defaults by us and other affiliates of EPCO.  An event of default, followed by a foreclosure on the pledged collateral, could ultimately result in a change in ownership of these units and affect the market price of the Partnership’s common units.

The Partnership and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates.  EPCO and its privately held affiliates use cash on hand and cash distributions they receive from us and other investments to fund their other activities and to meet their respective debt obligations, if any.  During the six months ended June 30, 2024 and 2023, we paid EPCO and its privately held affiliates cash distributions totaling $700 million and $666 million, respectively.

We have no employees.  All of our administrative and operating functions are provided either by employees of EPCO (pursuant to the ASA) or by other service providers.  We and our general partner are parties to the ASA.  The following table presents our related party costs and expenses attributable to the ASA with EPCO for the periods indicated:

We lease office space from privately held affiliates of EPCO at rental rates that approximate market rates.  For each of the three months ended June 30, 2024 and 2023, we recognized $4 million of related party operating lease expense in connection with these office space leases.  For each of the six months ended June 30, 2024 and 2023, we recognized $7 million of related party operating lease expense in connection with these office space leases.


Note 15.  Income Taxes

Income taxes are accounted for under the asset-and-liability method.  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.  We recognize the effect of income tax positions only if those positions are more likely than not of being sustained.  Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized.  Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.  We did not rely on any uncertain tax positions in recording our income tax-related amounts during the three and six months ended June 30, 2024 and 2023.

Our federal, state and foreign income tax benefit (provision) is summarized below:

Note 16.  Commitments and Contingent Liabilities

Litigation

As part of our normal business activities, we may be named as defendants in legal proceedings, including those arising from regulatory and environmental matters.  Although we are insured against various risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to fully indemnify us against losses arising from future legal proceedings.  We will vigorously defend the Partnership in litigation matters.

There were no accruals for litigation contingencies at June 30, 2024 and December 31, 2023, respectively.

Contractual Obligations

Scheduled Maturities of Debt
We have long-term and short-term payment obligations under debt agreements.  In total, the principal amount of our consolidated debt obligations were $30.6 billion and $29.0 billion at June 30, 2024 and December 31, 2023, respectively.  See Note 7 for additional information regarding our scheduled future maturities of debt principal.

Overview of Business

We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “EPD.”  Our preferred units are not publicly traded.  We were formed in April 1998 to own and operate certain natural gas liquids (“NGLs”) related businesses of EPCO and are a leading North American provider of midstream energy services to producers and consumers of natural gas, NGLs, crude oil, petrochemicals and refined products.  We are owned by our limited partners (preferred and common unitholders) from an economic perspective.  Enterprise GP, which owns a non-economic general partner interest in us, manages our Partnership.  We conduct substantially all of our business operations through EPO and its consolidated subsidiaries.

Our fully integrated, midstream energy asset network (or “value chain”) links producers of natural gas, NGLs and crude oil from some of the largest supply basins in the U.S., Canada and the Gulf of Mexico with domestic consumers and international markets.  Our midstream energy operations include:

•
natural gas gathering, treating, processing, transportation and storage;

•

Recent Developments

Issuance of $2.5 Billion of Senior Notes in August 2024

In August 2024, EPO issued $2.5 billion aggregate principal amount of senior notes comprised of (i) $1.1 billion principal amount of senior notes due February 2035 (“Senior Notes JJJ”) and (ii) $1.4 billion principal amount of senior notes due February 2055 (“Senior Notes KKK”).  Net proceeds from this offering will be used by EPO for general company purposes, including for growth capital investments, and the repayment of debt (including the repayment of all or a portion of our $1.15 billion principal amount of 3.75% Senior Notes MM at their maturity in February 2025).

Senior Notes JJJ were issued at 99.400% of their principal amount and have a fixed interest rate of 4.95% per year.  Senior Notes KKK were issued at 99.663% of their principal amount and have a fixed interest rate of 5.55% per year.  The Partnership guaranteed these senior notes through an unconditional guarantee on an unsecured and unsubordinated basis.

Enterprise to Expand LPG Export Capacity at EHT

In July 2024, we announced plans to move forward with the construction of a fourth refrigeration train at our Enterprise Hydrocarbon Terminal (“EHT”).  The addition of a fourth refrigeration train (“Ref 4”), which is expected to be placed into service by the end of 2026, will increase our propane and butane export capabilities by approximately 300 MBPD.  In addition to providing incremental LPG export capacity, Ref 4 will increase the instantaneous loading rates for propane and butane at EHT, while also making additional capacity available for propylene exports.

Enterprise Receives Deepwater Port License for SPOT Project

In April 2024, we received the deepwater port license for the Sea Port Oil Terminal (“SPOT”) from the U.S. Department of Transportation’s Maritime Administration.  The receipt of the deepwater port license is a significant milestone in the development and commercialization of SPOT.

As planned, SPOT would consist of proposed onshore and offshore facilities, including a fixed platform located approximately 30 nautical miles off the Texas coast in approximately 115 feet of water.  SPOT is designed to load Very Large Crude Carriers (“VLCCs”) and other crude oil tankers at rates of approximately 85,000 barrels per hour.  The platform would be connected to an onshore storage facility with approximately 4.8 MMBbls of capacity in Brazoria County, Texas, by two 36-inch, bi-directional pipelines.  The SPOT project includes state-of-the-art pipeline control, vapor recovery and leak detection systems that are designed to minimize emissions.  SPOT would provide customers with an efficient export solution that leverages our extensive integrated supply, storage and distribution network.

We continue our efforts to commercialize this project in order to support a final investment decision.

Enterprise to Build Mentone West 2; Mentone 3 and Leonidas Begin Service

In April 2024, we announced plans to further expand our natural gas processing capabilities in the Delaware Basin with construction of a second natural gas processing train at our Mentone West location (“Mentone West 2”) in Loving County, Texas.  This natural gas processing train, which will have the capacity to process more than 300 MMcf/d of natural gas and extract in excess of 40 MBPD of NGLs, is expected to begin service during the first half of 2026.

Additionally, we placed into service our third natural gas processing train at Mentone in the Delaware Basin (“Mentone 3”) and our seventh Midland Basin natural gas processing train (“Leonidas”).  Both Mentone 3 and Leonidas are capable of processing over 300 MMcf/d of natural gas and extracting more than 40 MBPD of NGLs.  Supported by a combination of long-term producer dedications and minimum volume commitments, Mentone 3 and Leonidas will support Permian Basin producers as they meet growing demand in the U.S. and internationally.

Enterprise Begins Initial Service on TW Products System

In March 2024, we placed into service the first phase of our Texas Western Products System (“TW Products System”) and began truck loading operations at our new Permian terminal in Gaines County, Texas.  This facility features approximately 900,000 barrels of storage for gasoline and diesel, and truck loading capacity of 10 MBPD.  Additionally, we placed into service and began truck loading operations at our Jal and Moriarty Terminals located in New Mexico during the second quarter of 2024.  We expect the Grand Junction Terminal located in Utah to be placed into service in the third quarter of 2024.

Enterprise Acquires Equity Interests from Western Midstream

In February 2024, we announced that we had acquired the remaining equity interests in Whitethorn Pipeline Company LLC (“Whitethorn”) and Enterprise EF78 LLC (“EF78”) from affiliates of Western Midstream Partners, LP (“Western Midstream”) for $375 million in total cash consideration.  This transaction, which closed on February 16, 2024, was funded using cash on hand and proceeds from the issuance of short-term notes under our commercial paper program.

Additionally, on March 27, 2024, we acquired an additional 15% equity interest in Panola Pipeline Company, LLC (“Panola”) from an affiliate of Western Midstream for $25 million in cash consideration.  We funded the cash consideration using cash on hand.

Issuance of $2.0 Billion of Senior Notes in January 2024

In January 2024, EPO issued $2.0 billion aggregate principal amount of senior notes comprised of (i) $1.0 billion principal amount of senior notes due January 2027 (“Senior Notes HHH”) and (ii) $1.0 billion principal amount of senior notes due January 2034 (“Senior Notes III”).  Net proceeds from this offering were used by EPO for general company purposes, including for growth capital investments, and the repayment of debt (including the repayment of all of our $850 million principal amount of 3.90% Senior Notes JJ at their maturity in February 2024 and amounts outstanding under our commercial paper program).

Senior Notes HHH were issued at 99.897% of their principal amount and have a fixed interest rate of 4.60% per year.  Senior Notes III were issued at 99.705% of their principal amount and have a fixed interest rate of 4.85% per year.   The Partnership guaranteed these senior notes through an unconditional guarantee on an unsecured and unsubordinated basis.

Polymer grade propylene prices represent average contract pricing for such product as reported by IHS Markit (“IHS”), which is a division of S&P Global, Inc.  Refinery grade propylene (“RGP”) prices represent weighted-average spot prices for such product as reported by IHS.
(4)
The “Indicative Gas Processing Gross Spread” represents our generic estimate of the gross economic benefit from extracting NGLs from natural gas production based on certain pricing assumptions.  Specifically, it is the amount by which the assumed economic value of a composite gallon of NGLs in Chambers County, Texas exceeds the value of the equivalent amount of energy in natural gas at Henry Hub, Louisiana.  Our estimate of the indicative spread does not consider the operating costs incurred by a natural gas processing facility to extract the NGLs nor the transportation and fractionation costs to deliver the NGLs to market.  In addition, the actual gas processing spread earned at each plant is further influenced by regional pricing and extraction dynamics.

The weighted-average indicative market price for NGLs was $0.59 per gallon in the second quarter of 2024 versus $0.55 per gallon in the second quarter of 2023.  Likewise, the weighted-average indicative market price for NGLs was $0.61 per gallon during each of the six months ended June 30, 2024 and 2023.

Fluctuations in our consolidated revenues and cost of sales amounts are explained in large part by changes in energy commodity prices.  An increase in our consolidated marketing revenues due to higher energy commodity sales prices may not result in an increase in gross operating margin or cash available for distribution, since our consolidated cost of sales amounts would also be expected to increase due to comparable increases in the purchase prices of the underlying energy commodities.  The same type of relationship would be true in the case of lower energy commodity sales prices and purchase costs.

We attempt to mitigate commodity price exposure through our hedging activities and the use of fee-based arrangements.  See Note 13 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report and “Quantitative and Qualitative Disclosures About Market Risk” under Part I, Item 3 of this quarterly report for information regarding our commodity hedging activities.

Impact of Inflation

Inflation rates in the U.S. increased significantly in 2022 and remain elevated in 2024 compared to recent historical levels.  While pandemic-era supply chain disruptions have largely dissipated and measures taken by the U.S. Federal Reserve Bank have helped slow the growth of inflation, the high cost environment that began in 2022 generally remains intact in 2024.  However, to the extent that a rising cost environment impacts our results, there are typically offsetting benefits either inherent in our business or that result from other steps we take proactively to reduce the impact of inflation on our net operating results.  These benefits include: (1) provisions included in our long-term fee-based revenue contracts that offset cost increases in the form of rate escalations based on positive changes in the U.S. Consumer Price Index, Producer Price Index for Finished Goods or other factors; (2) provisions in other revenue contracts that enable us to pass through higher energy costs to customers in the form of gas, electricity and fuel rebills or surcharges; and (3) higher commodity prices, which generally enhance our results in the form of increased volumetric throughput and demand for our services.  Additionally, we take measures to mitigate the impact of cost increases in certain commodities, including a portion of our electricity needs, using fixed-price, term purchase agreements or financial derivatives.  For these reasons, the increased cost environment, caused in part by inflation, has not had a material impact on our historical results of operations for the periods presented in this report.  However, a significant or prolonged period of high inflation could adversely impact our results if costs were to increase at a rate greater than the increase in the revenues we receive.

See “Capital Investments” within this Part I, Item 2 for a discussion of the impact of inflation on our capital investment decisions.

The weighted-average interest rates on debt principal outstanding during the three and six months ended June 30, 2024 were 4.62% and 4.61%, respectively.  The weighted-average interest rate on debt principal outstanding during the three and six months ended June 30, 2023 were 4.58% and 4.57%, respectively.
(2)
We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase.  Capitalized interest amounts become part of the historical cost of an asset and are charged to earnings (as a component of depreciation expense) on a straight-line basis over the estimated useful life of the asset once the asset enters its intended service.  When capitalized interest is recorded, it reduces interest expense from what it would be otherwise.  Capitalized interest amounts fluctuate based on the timing of when projects are placed into service, our capital investment levels and the interest rates charged on borrowings.

Interest charged on debt principal outstanding, which is a key driver of interest expense, increased a net $17 million quarter-to-quarter.  This increase was primarily due to the issuance of $2.0 billion fixed-rate senior notes in January 2024, which accounted for a $24 million increase, partially offset by a $8 million decrease as a result of the retirement of $850 million of fixed-rate senior notes in February 2024.

Interest charged on debt principal outstanding increased a net $31 million period-to-period.  This increase was primarily due to the aforementioned issuance of senior notes, which accounted for a $45 million increase, partially offset by a $21 million decrease as a result of the retirement of $1.25 billion and $850 million of fixed-rate senior notes in March 2023 and February 2024, respectively.

For additional information regarding our debt obligations, see Note 7 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.  For a discussion of our capital projects, see “Capital Investments” within this Part I, Item 2.

Income taxes

Our income taxes are primarily comprised of our state tax obligations under the Revised Texas Franchise Tax (“Texas Margin Tax”).  Our provision for income taxes for the three and six months ended June 30, 2024 increased $2 million and $13 million, respectively, when compared to the same periods in 2023.

Business Segment Highlights

Our operations are reported under four business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services and (iv) Petrochemical & Refined Products Services.  Our business segments are generally organized and managed according to the types of services rendered (or technologies employed) and products produced and/or sold.

We evaluate segment performance based on our financial measure of gross operating margin.  Gross operating margin is an important performance measure of the core profitability of our operations and forms the basis of our internal financial reporting.  We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results. 

The following table presents gross operating margin by segment and total gross operating margin, a non-generally accepted accounting principle (“non-GAAP”) financial measure, for the periods indicated (dollars in millions):

Within the context of this table, total segment gross operating margin represents a subtotal and corresponds to measures similarly titled within our business segment disclosures found under Note 10 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Gross operating margin includes equity in the earnings of unconsolidated affiliates, but is exclusive of other income and expense transactions, income taxes, the cumulative effect of changes in accounting principles and extraordinary charges.  Gross operating margin is presented on a 100% basis before any allocation of earnings to noncontrolling interests.  Our calculation of gross operating margin may or may not be comparable to similarly titled measures used by other companies.  Segment gross operating margin for NGL Pipelines & Services and Crude Oil Pipelines & Services reflect adjustments for shipper make-up rights that are included in management’s evaluation of segment results.  However, these adjustments are excluded from non-GAAP total gross operating margin.

The GAAP financial measure most directly comparable to total gross operating margin is operating income.  For a discussion of operating income and its components, see the previous section titled “Income Statement Highlights” within this Part I, Item 2.  The following table presents a reconciliation of operating income to total gross operating margin for the periods indicated (dollars in millions):

Each of our business segments benefits from the supporting role of our marketing activities.  The main purpose of our marketing activities is to support the utilization and expansion of assets across our midstream energy asset network by increasing the volumes handled by such assets, which results in additional fee-based earnings for each business segment.  In performing these support roles, our marketing activities also seek to participate in supply and demand opportunities as a supplemental source of gross operating margin for us.  The financial results of our marketing efforts fluctuate due to changes in volumes handled and overall market conditions, which are influenced by current and forward market prices for the products bought and sold.

Propylene production and related activities
Second Quarter of 2024 Compared to Second Quarter of 2023.  Gross operating margin from propylene production and related activities for the second quarter of 2024 increased $6 million when compared to the second quarter of 2023.

On a combined basis, gross operating margin from our Mont Belvieu area propylene production facilities increased a net $10 million quarter-to-quarter primarily due to higher propylene processing revenues, which accounted for a $38 million increase, and higher average propylene sales margins, which accounted for an additional $15 million increase, partially offset by lower propylene sales volumes, which accounted for a $37 million decrease, and higher operating costs, which accounted for an additional $9 million decrease.  Propylene and associated by-product production volumes at these facilities increased a combined 12 MBPD (net to our interest) quarter-to-quarter primarily due to contributions from our PDH 2 facility, which was placed into service in July 2023, and higher production from our propylene splitters, which underwent scheduled maintenance during the second quarter of 2023.  Partially offsetting this increase was lower production from our PDH 1 facility due to scheduled maintenance that was completed during the second quarter of 2024.  Our PDH 2 facility experienced downtime beginning in June 2024 to address start up issues that once resolved will allow us to achieve nameplate production capacity.  We anticipate a resumption of operations at the PDH 2 facility during the third quarter of 2024.

Six Months Ended June 30, 2024 Compared to Six Months Ended June 30, 2023.  Gross operating margin from propylene production and related activities for the six months ended June 30, 2024 decreased $39 million when compared to the six months ended June 30, 2023.

On a combined basis, gross operating margin from our Mont Belvieu area propylene production facilities decreased a net $28 million period-to-period primarily due to lower propylene sales volumes, which accounted for a $74 million decrease, and higher operating costs, which accounted for an additional $44 million decrease, partially offset by higher propylene processing revenues, which accounted for a $78 million increase, and higher storage and other revenues, which accounted for an additional $9 million increase.  Propylene and associated by-product production volumes at these facilities increased a combined 6 MBPD (net to our interest) period-to-period primarily due to contributions from our PDH 2 facility, which was placed into service in July 2023, partially offset by downtime for maintenance at our PDH 1 facility during the first half of 2024.

Liquidity and Capital Resources

Based on current market conditions (as of the filing date of this quarterly report), we believe that the Partnership and its consolidated businesses will have sufficient liquidity, cash flow from operations and access to capital markets to fund their capital investments and working capital needs for the reasonably foreseeable future.  At June 30, 2024, we had $3.4 billion of consolidated liquidity.  This amount was comprised of $3.3 billion of available borrowing capacity under EPO’s revolving credit facilities, which is the net of $4.2 billion of total borrowing capacity under EPO’s revolving credit facilities and $900 million outstanding under EPO’s commercial paper program, and $138 million of unrestricted cash on hand.

We may issue debt and equity securities to assist us in meeting our future funding and liquidity requirements, including those related to capital investments.  We have a universal shelf registration statement on file with the SEC which allows the Partnership and EPO to issue an unlimited amount of equity and debt securities, respectively.  In addition, we have a registration statement on file with the SEC covering the issuance of up to $2.5 billion of the Partnership’s common units in amounts, at prices and on terms based on market conditions and other factors at the time of such offerings (referred to as the Partnership’s at-the-market (“ATM”) program).

Enterprise Declares Cash Distribution for Second Quarter of 2024

On July 10, 2024, we announced that the Board declared a quarterly cash distribution of $0.525 per common unit, or $2.10 per unit on an annualized basis, to be paid to the Partnership’s common unitholders with respect to the second quarter of 2024.  The quarterly distribution is payable on August 14, 2024 to unitholders of record as of the close of business on July 31, 2024.  The total amount to be paid is $1.15 billion, which includes $11 million for distribution equivalent rights on phantom unit awards.

The payment of quarterly cash distributions is subject to management’s evaluation of our financial condition, results of operations and cash flows in connection with such payments and Board approval.  Management will evaluate any future increases in cash distributions on a quarterly basis.

In January 2024, EPO issued $2.0 billion aggregate principal amount of senior notes comprised of (i) $1.0 billion principal amount of senior notes due January 2027 (“Senior Notes HHH”) and (ii) $1.0 billion principal amount of senior notes due January 2034 (“Senior Notes III”).  Senior Notes HHH were issued at 99.897% of their principal amount and have a fixed interest rate of 4.60% per year.  Senior Notes III were issued at 99.705% of their principal amount and have a fixed interest rate of 4.85% per year.  Net proceeds from this offering were used by EPO for general company purposes, including for growth capital investments, and the repayment of debt (including the repayment of all of our $850 million principal amount of 3.90% Senior Notes JJ at their maturity in February 2024 and amounts outstanding under our commercial paper program).

In March 2024, EPO entered into a new 364-Day Revolving Credit Agreement (the “March 2024 $1.5 Billion 364-Day Revolving Credit Agreement”) that replaced its prior 364-day revolving credit agreement.  The March 2024 $1.5 Billion 364-Day Revolving Credit Agreement matures in March 2025.  EPO’s borrowing capacity was unchanged from the prior 364-day revolving credit agreement.  As of June 30, 2024, there are no principal amounts outstanding under this new revolving credit agreement.

In August 2024, EPO issued $2.5 billion aggregate principal amount of senior notes comprised of (i) $1.1 billion principal amount of senior notes due February 2035 (“Senior Notes JJJ”) and (ii) $1.4 billion principal amount of senior notes due February 2055 (“Senior Notes KKK”).   Senior Notes JJJ were issued at 99.400% of their principal amount and have a fixed interest rate of 4.95% per year.  Senior Notes KKK were issued at 99.663% of their principal amount and have a fixed interest rate of 5.55% per year.  Net proceeds from this offering will be used by EPO for general company purposes, including for growth capital investments, and the repayment of debt (including the repayment of all or a portion of our $1.15 billion principal amount of 3.75% Senior Notes MM at their maturity in February 2025).

For additional information regarding our consolidated debt obligations, see Notes 7 and 18 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Credit Ratings

As of August 9, 2024, the investment-grade credit ratings of EPO’s long-term senior unsecured debt securities were A- from Standard and Poor’s, A3 from Moody’s and A- from Fitch Ratings.  In addition, the credit ratings of EPO’s short-term senior unsecured debt securities were A-2 from Standard and Poor’s, P-2 from Moody’s and F-2 from Fitch Ratings.  EPO’s credit ratings reflect only the view of a rating agency and should not be interpreted as a recommendation to buy, sell or hold any of our securities.  A credit rating can be revised upward or downward or withdrawn at any time by a rating agency, if it determines that circumstances warrant such a change.  A credit rating from one rating agency should be evaluated independently of credit ratings from other rating agencies.

Common Unit Repurchases Under 2019 Buyback Program

In January 2019, we announced that the Board had approved a $2.0 billion multi-year unit buyback program (the “2019 Buyback Program”), which provides the Partnership with an additional method to return capital to investors.  The Partnership repurchased 1,419,581 and 2,806,416 common units through open market purchases during the three and six months ended June 30, 2024, respectively.  The total cost of these repurchases, including commissions and fees, was $40 million and $80 million, respectively.  As of June 30, 2024, the remaining available capacity under the 2019 Buyback Program was $1.0 billion.

Net cash flow provided by operating activities are largely dependent on earnings from our consolidated business activities. Changes in energy commodity prices may impact the demand for natural gas, NGLs, crude oil, petrochemicals and refined products, which could impact sales of our products and the demand for our midstream services.  Changes in demand for our products and services may be caused by other factors, including prevailing economic conditions, reduced demand by consumers for the end products made with hydrocarbon products, increased competition, public health emergencies, adverse weather conditions and government regulations affecting prices and production levels.  We may also incur credit and price risk to the extent customers do not fulfill their contractual obligations to us in connection with our marketing activities and long-term take-or-pay and dedication agreements.  For a more complete discussion of these and other risk factors pertinent to our business, see “Risk Factors” included under Part I, Item 1A of the 2023 Form 10-K.

For additional information regarding our cash flow amounts, please refer to the Unaudited Condensed Statements of Consolidated Cash Flows included under Part I, Item 1 of this quarterly report.

The following information highlights significant period-to-period fluctuations in our consolidated cash flow amounts:

Operating activities
Net cash flow provided by operating activities for the six months ended June 30, 2024 increased a net $200 million when compared to the six months ended June 30, 2023 primarily due to:

•
a $337 million period-to-period increase resulting from higher partnership earnings (determined by adjusting our $200 million period-to-period increase in net income for changes in the non-cash items identified on our Unaudited Condensed Statements of Consolidated Cash Flows); partially offset by

•
a $124 million period-to-period decrease from changes in operating accounts primarily due to the use of working capital employed in our marketing activities, which includes the impact of (i) fluctuations in commodity prices, (ii) timing of our inventory purchase and sale strategies, and (iii) changes in margin deposit requirements associated with our commodity derivative instruments.

For information regarding significant period-to-period changes in our consolidated net income and underlying segment results, see “Income Statement Highlights” and “Business Segment Highlights” within this Part I, Item 2.

Investing activities
Net cash flow used in investing activities during the six months ended June 30, 2024 increased $879 million when compared to the six months ended June 30, 2023 primarily due to an increase in investments for property, plant and equipment (see “Capital Investments” within this Part I, Item 2 for additional information).

Table of Contents

Financing activities
Net cash flow used in financing activities during the six months ended June 30, 2024 decreased a net $722 million when compared to the six months ended June 30, 2023 primarily due to:

•
a net cash inflow of $1.5 billion related to debt transactions that occurred during the six months ended June 30, 2024 compared to a net cash inflow of $361 million related to debt transactions that occurred during the six months ended June 30, 2023.  During the six months ended June 30, 2024, we issued $2.0 billion aggregate principal amount of senior notes and issued a net $450 million under EPO’s commercial paper program, partially offset by the repayment of $850 million principal amount of senior notes.  During the six months ended June 30, 2023, we issued $1.75 billion aggregate principal amount of senior notes, partially offset by the repayment of $1.25 billion principal amount of senior notes and net repayments of $140 million under EPO’s commercial paper program; partially offset by

•
a $400 million cash outflow during the six months ended June 30, 2024 in connection with the acquisition of noncontrolling interests.  In February 2024, we acquired the remaining 20% equity interest in Whitethorn and remaining 25% equity interest in EF78 from affiliates of Western Midstream for total cash consideration of $375 million.  In March 2024, we acquired an additional 15% equity interest in Panola from an affiliate of Western Midstream for $25 million in cash consideration; and

•
a $106 million period-to-period increase in cash distributions paid to common unitholders primarily attributable to increases in the quarterly cash distribution rate per unit.

Non-GAAP Cash Flow Measures

Distributable Cash Flow and Operational Distributable Cash Flow
Our partnership agreement requires us to make quarterly distributions to our common unitholders of all available cash, after any cash reserves established by Enterprise GP in its sole discretion.  Cash reserves include those for the proper conduct of our business, including those for capital investments, debt service, working capital, operating expenses, common unit repurchases, commitments and contingencies and other amounts.  The retention of cash allows us to reinvest in our growth and reduce our future reliance on the equity and debt capital markets.  

We measure available cash by reference to distributable cash flow (“DCF”), which is a non-GAAP liquidity measure.  DCF is an important financial measure for our common unitholders since it serves as an indicator of our success in providing a cash return on investment.  Specifically, this financial measure indicates to investors whether or not we are generating cash flows at a level that can sustain our declared quarterly cash distributions.  DCF is also a quantitative standard used by the investment community with respect to publicly traded partnerships since the value of a partnership unit is, in part, measured by its yield, which is based on the amount of cash distributions a partnership can pay to a unitholder.  Our management compares the DCF we generate to the cash distributions we expect to pay our common unitholders.  Using this metric, management computes our distribution coverage ratio.   Our calculation of DCF may or may not be comparable to similarly titled measures used by other companies.

Based on the level of available cash each quarter, management proposes a quarterly cash distribution rate to the Board, which has sole authority in approving such matters.  Enterprise GP has a non-economic ownership interest in the Partnership and is not entitled to receive any cash distributions from it based on incentive distribution rights or other equity interests.

Operational distributable cash flow (“Operational DCF”), which is defined as DCF excluding the impact of proceeds from asset sales and other matters and monetization of interest rate derivative instruments, is a supplemental non-GAAP liquidity measure that quantifies the portion of cash available for distribution to common unitholders that was generated from our normal operations.  We believe that it is important to consider this non-GAAP measure as it provides an enhanced perspective of our assets’ ability to generate cash flows without regard for certain items that do not reflect our core operations.

Our use of DCF and Operational DCF for the limited purposes described above and in this quarterly report is not a substitute for net cash flow provided by operating activities, which is the most comparable GAAP measure to DCF and Operational DCF.  For a discussion of net cash flow provided by operating activities, see “Cash Flow Statement Highlights” within this Part I, Item 2.

Capital Investments

Since the beginning of 2024, we placed into service two natural gas processing trains in the Permian Basin and the first and part of the second phase of our TW Products System.  We have approximately $6.7 billion of growth capital projects scheduled to be completed by the end of 2026, including the following major projects (including their respective scheduled completion dates):

•
natural gas gathering expansion projects in the Delaware and Midland Basins (2024 and 2025);

•
the Bahia NGL Pipeline (first half of 2025);

•
an NGL fractionator (“Frac 14”) and an associated DIB unit at our Mont Belvieu area NGL fractionation complex (second half of 2025);

•
our first natural gas processing train at our Mentone West location in the Delaware Basin (second half of 2025);

•
an eighth natural gas processing train (“Orion”) in the Midland Basin (second half of 2025);

•
an expansion of our Morgan’s Point terminal to increase ethylene export capacity (second half of 2024 and second half of 2025);

•
our Neches River Ethane / Propane Export Facility located in Orange County, Texas (second half of 2025 and first half of 2026);

•
our second natural gas processing train at our Mentone West location in the Delaware Basin (first half of 2026); and

•
the expansion of our LPG and PGP export capacity at EHT, including Ref 4 (fourth quarter of 2026).

Based on information currently available, we expect our total capital investments for 2024, net of contributions from noncontrolling interests, to approximate $4.1 billion to $4.35 billion, which reflects growth capital investments of $3.5 billion to $3.75 billion and sustaining capital expenditures of $600 million.  These amounts do not include capital investments associated with our proposed deep-water offshore crude oil terminal (SPOT), which remains subject to a final investment decision.

Table of Contents

Our forecast of capital investments is dependent upon our ability to generate the required funds from either operating cash flow or other means, including borrowings under debt agreements, the issuance of additional equity and debt securities, and potential divestitures.  We may revise our forecast of capital investments due to factors beyond our control, such as adverse economic conditions, weather-related issues and changes in supplier prices resulting from raw material or labor shortages, supply chain disruptions or inflation.  Furthermore, our forecast of capital investments may change over time based on future decisions by management, which may include changing the scope or timing of projects or cancelling projects altogether.  Our success in raising capital, having the ability to increase revenues commensurate with cost increases and our ability to partner with other companies to share project costs and risks, continue to be significant factors in determining how much capital we can invest.  We believe our access to capital resources is sufficient to meet the demands of our current and future growth needs and, although we currently expect to make the forecast capital investments noted above, we may revise our plans in response to changes in economic and capital market conditions.

The following table summarizes our capital investments for the periods indicated (dollars in millions):

(1)
Growth and sustaining capital amounts presented in the table above are presented on a cash basis.  In total, these amounts represent “Capital expenditures” as presented on our Unaudited Condensed Statements of Consolidated Cash Flows.
(2)
Growth capital projects either (a) result in new sources of cash flow due to enhancements of or additions to existing assets (e.g., additional revenue streams, cost savings resulting from debottlenecking of a facility, etc.) or (b) expand our asset base through construction of new facilities that will generate additional revenue streams and cash flows.
(3)
Sustaining capital projects are capital expenditures (as defined by GAAP) resulting from improvements to existing assets.  Such expenditures serve to maintain existing operations but do not generate additional revenues or result in significant cost savings. Sustaining capital expenditures include the costs of major maintenance activities at our reaction-based plants, which are accounted for using the deferral method.

Comparison of Six Months Ended June 30, 2024 with Six Months Ended June 30, 2023

In total, investments in growth capital projects increased $710 million period-to-period primarily due to the following:

•
higher investments in ethane, ethylene, and LPG export expansion projects at our Gulf Coast terminals, which accounted for a $291 million increase;

•
higher investments in our Bahia NGL Pipeline, which accounted for a $242 million increase; and

•
higher investments in the construction of natural gas processing trains and related gathering system expansions in the Delaware and Midland Basins, which accounted for an additional $149 million increase.

Investments attributable to sustaining capital projects increased $168 million period-to-period primarily due to higher major maintenance activities performed at certain of our reaction-based plants (e.g., our PDH 1 and iBDH facilities) and fluctuations in timing and costs of pipeline integrity and similar projects.

Critical Accounting Policies and Estimates

A discussion of our critical accounting policies and estimates is included in our 2023 Form 10-K.  The following types of estimates, in our opinion, are subjective in nature, require the exercise of professional judgment and involve complex analysis:

•
depreciation methods and estimated useful lives of property, plant and equipment;

•
measuring recoverability of long-lived assets and fair value of equity method investments;

•
amortization methods of customer relationships and contract-based intangible assets;

•
methods we employ to measure the fair value of goodwill and related assets; and

•
the use of estimates for revenue and expenses.

When used to prepare our Unaudited Condensed Consolidated Financial Statements, the foregoing types of estimates are based on our current knowledge and understanding of the underlying facts and circumstances.  Such estimates may be revised as a result of changes in the underlying facts and circumstances.  Subsequent changes in these estimates may have a significant impact on our consolidated financial position, results of operations and cash flows.

Other Matters

Parent-Subsidiary Guarantor Relationship

The Partnership (the “Parent Guarantor”) has guaranteed the payment of principal and interest on the consolidated debt obligations of EPO (the “Subsidiary Issuer”), with the exception of the remaining debt obligations of TEPPCO Partners, L.P. (collectively, the “Guaranteed Debt”).  If EPO were to default on any of its Guaranteed Debt, the Partnership would be responsible for full and unconditional repayment of such obligations.  At June 30, 2024, the total amount of Guaranteed Debt was $31.1 billion, which was comprised of $27.4 billion of EPO’s senior notes, $2.3 billion of EPO’s junior subordinated notes, $900 million of short-term commercial paper notes, and $487 million of related accrued interest.

The Partnership’s guarantees of EPO’s senior note obligations, commercial paper notes and borrowings under bank credit facilities represent unsecured and unsubordinated obligations of the Partnership that rank equal in right of payment to all other existing or future unsecured and unsubordinated indebtedness of the Partnership.  In addition, these guarantees effectively rank junior in right of payment to any existing or future indebtedness of the Partnership that is secured and unsubordinated, to the extent of the assets securing such indebtedness.

The Partnership’s guarantees of EPO’s junior subordinated notes represent unsecured and subordinated obligations of the Partnership that rank equal in right of payment to all other existing or future subordinated indebtedness of the Partnership and senior in right of payment to all existing or future equity securities of the Partnership.  The Partnership’s guarantees of EPO’s junior subordinated notes effectively rank junior in right of payment to (i) any existing or future indebtedness of the Partnership that is secured, to the extent of the assets securing such indebtedness and (ii) all other existing or future unsecured and unsubordinated indebtedness of the Partnership.

The Partnership may be released from its guarantee obligations only in connection with EPO’s exercise of its legal or covenant defeasance options as described in the underlying agreements.

Selected Financial Information of Obligor Group
The following tables present summarized financial information of the Partnership (as Parent Guarantor) and EPO (as Subsidiary Issuer) on a combined basis (collectively, the “Obligor Group”), after the elimination of intercompany balances and transactions among the Obligor Group.

In accordance with Rule 13.01 of Regulation S-X, the summarized financial information of the Obligor Group excludes the Obligor Group’s equity in income and investments in the consolidated subsidiaries of EPO that are not party to the guarantee obligations (the “Non-Obligor Subsidiaries”).  The total carrying value of the Obligor Group’s investments in the Non-Obligor Subsidiaries was $49.7 billion at June 30, 2024.  The Obligor Group’s equity in the earnings of the Non-Obligor Subsidiaries for the six months ended June 30, 2024 was $3.2 billion.  Although the net assets and earnings of the Non-Obligor Subsidiaries are not directly available to the holders of the Guaranteed Debt to satisfy the repayment of such obligations, there are no significant restrictions on the ability of the Non-Obligor Subsidiaries to pay distributions or make loans to EPO or the Partnership.  EPO exercises control over the Non-Obligor Subsidiaries.  We continue to believe that the unaudited condensed consolidated financial statements of the Partnership presented under Part I, Item 1 of this quarterly report provide a more appropriate view of our credit standing.  Our investment grade credit ratings are based on the Partnership’s consolidated financial statements and not the Obligor Group’s financial information presented below.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES
ABOUT MARKET RISK.

General

In the normal course of our business operations, we are exposed to certain risks, including changes in interest rates and commodity prices.  In order to manage risks associated with assets, liabilities and certain anticipated future transactions, we use derivative instruments such as futures, forward contracts, swaps and other instruments with similar characteristics.  Substantially all of our derivatives are used for non-trading activities.

We assess the risk associated with each of our derivative instrument portfolios using a sensitivity analysis model.  This approach measures the change in fair value of the derivative instrument portfolio based on a hypothetical 10% change in the underlying interest rates or quoted market prices on a particular day.  In addition to these variables, the fair value of each portfolio is influenced by changes in the notional amounts of the instruments outstanding.  The sensitivity analysis approach does not reflect the impact that the same hypothetical price movement would have on the hedged exposures to which they relate.  Therefore, the impact on the fair value of a derivative instrument resulting from a change in interest rates or quoted market prices (as applicable) would normally be offset by a corresponding gain or loss on the hedged debt instrument, inventory value or forecasted transaction assuming:

•
the derivative instrument functions effectively as a hedge of the underlying risk;

•
the derivative instrument is not closed out in advance of its expected term; and

•
the hedged forecasted transaction occurs within the expected time period.

We routinely review the effectiveness of our derivative instrument portfolios in light of current market conditions.  Accordingly, the nature and volume of our derivative instruments may change depending on the specific exposure being managed.

Table of Contents

Commodity Hedging Activities

The price of energy commodities such as natural gas, NGLs, crude oil, petrochemicals and refined products and power are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control.  In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps and basis swaps.

At June 30, 2024, our predominant commodity hedging strategies consisted of (i) hedging anticipated future purchases and sales of commodity products associated with transportation, storage and blending activities, (ii) hedging natural gas processing margins, (iii) hedging the fair value of commodity products held in inventory and (iv) hedging anticipated future purchases of power for certain operations in Southeast Texas.  For a summary of our portfolio of commodity derivative instruments outstanding, see Note 13 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

Sensitivity Analysis

The following tables show the effect of hypothetical price movements on the estimated fair values of our principal commodity derivative instrument portfolios at the dates indicated (dollars in millions).

The fair value information presented in the sensitivity analysis tables excludes the impact of applying Chicago Mercantile Exchange (“CME”) Rule 814, which deems that financial instruments cleared by the CME are settled daily in connection with variation margin payments.  As a result of this exchange rule, CME-related derivatives are considered to have no fair value at the balance sheet date for financial reporting purposes; however, the derivatives remain outstanding and subject to future commodity price fluctuations until they are settled in accordance with their contractual terms.  Derivative transactions cleared on exchanges other than the CME (e.g., the Intercontinental Exchange or ICE) continue to be reported on a gross basis.

Interest Rate Hedging Activities

We may utilize interest rate swaps, forward-starting swaps, options to enter into forward-starting swaps (“swaptions”), treasury locks and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements.  This strategy may be used in controlling our overall cost of capital associated with such borrowings.  As of the filing date of this quarterly report, we do not have any interest rate hedging instruments outstanding.


ITEM 4.  CONTROLS AND PROCEDURES.

Disclosure Controls and Procedures

As of the end of the period covered by this quarterly report, our management carried out an evaluation, with the participation of (i) A. James Teague, Co-Chief Executive Officer of Enterprise GP, (ii) W. Randall Fowler, Co-Chief Executive Officer of Enterprise GP and (iii) R. Daniel Boss, Executive Vice President and Chief Financial Officer of Enterprise GP, of the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 of the Securities Exchange Act of 1934.  Based on this evaluation, as of the end of the period covered by this quarterly report, Messrs. Teague, Fowler and Boss concluded:

(i)
that our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive and financial officers, as appropriate to allow for timely decisions regarding required disclosures; and

(ii)
that our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) during the second quarter of 2024, that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. 

Section 302 and 906 Certifications

The required certifications of Messrs. Teague, Fowler and Boss under Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 are included as exhibits to this quarterly report (see Exhibits 31 and 32 under Part II, Item 6 of this quarterly report).

PART II.  OTHER INFORMATION.

ITEM 1.  LEGAL PROCEEDINGS.

As part of our normal business activities, we may be named as defendants in litigation and legal proceedings, including those arising from regulatory and environmental matters.  Although we are insured against various risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to indemnify us against liabilities arising from future legal proceedings.  We will vigorously defend the Partnership in litigation matters.

For additional information regarding our litigation matters, see Note 16 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

On occasion, we are assessed monetary penalties by governmental authorities related to administrative or judicial proceedings involving environmental matters.  The following information summarizes matters where the eventual resolution of each of these matters may result in monetary sanctions in excess of $0.3 million.  We do not expect that any expenditures related to the following matters will be material to our consolidated financial statements.  

•
In June 2019, we received a Notice of Violation from the U.S. Environmental Protection Agency (“EPA”) in connection with regulatory requirements applicable to facilities that we operate near Baton Rouge, Louisiana.  

•
In July 2021, we received a civil penalty demand from the U.S. Department of Justice and the State of Colorado regarding alleged violations of hydrocarbon leak detection and repair regulations applicable to our Meeker gas processing plant in Colorado.

•
In August 2022, we received a Notice of Violation from the U.S. EPA alleging that gasoline at two of our refined products terminals in Texas had exceeded certain Clean Air Act-related standards during two past regulatory control periods.

•
In August 2022, we received two Notices of Enforcement from the Texas Commission on Environmental Quality for alleged exceedances of air permit emission limits at our PDH 1 and iBDH facilities in Texas.


ITEM 1A.  RISK FACTORS.

An investment in our securities involves certain risks.  Security holders and potential investors in our securities should carefully consider the risks described under “Risk Factors” set forth in Part I, Item 1A of our 2023 Form 10-K, in addition to other information in such annual report and this quarterly report.  The risk factors set forth in our 2023 Form 10-K are important factors that could cause our actual results to differ materially from those contained in any written or oral forward-looking statements made by us or on our behalf.

ITEM 2.  UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS.

Recent Issuances of Unregistered Securities

Holders of our Series A Cumulative Convertible Preferred Units (“preferred units”) are entitled to receive cumulative quarterly distributions at a rate of 7.25% per annum.  We may satisfy our obligation to pay distributions to the preferred unitholders through the issuance, in whole or in part, of additional preferred units (referred to as paid-in-kind or “PIK” distributions), with the remainder in cash, subject to certain rights of a holder to elect all cash and other conditions as described in our partnership agreement.

The Partnership made quarterly PIK distributions to preferred unitholders in the first and second quarters of 2024 of 19,423 and 19,865 preferred units, respectively.  With the exception of 90 preferred units distributed in the second quarter of 2024 to an unaffiliated third party, all of the PIK distributions made during the six months ended June 30, 2024 were to OTA Holdings, Inc., an indirect, wholly owned subsidiary of the Partnership (“OTA”).  The preferred units held by OTA are accounted for as treasury units in consolidation.  For additional information regarding the preferred units, see Note 8 of the Notes to Unaudited Condensed Consolidated Financial Statements included under Part I, Item 1 of this quarterly report.

The issuance of preferred units as PIK distributions during the three and six months ended June 30, 2024 were undertaken in reliance upon an exemption from the registration requirements of the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) thereof.

Other than as described above, there were no sales of unregistered equity securities during the second quarter of 2024.
