On November 12, 2025, Targa Resources Corp. (the "Company"), along with certain of its subsidiaries (the "Subsidiary Guarantors"), completed the previously announced underwritten public offering (the "Offering") of (i) $750.0 million aggregate principal amount of the Company's 4.350% Senior Notes due 2029 (the "2029 Notes") and (ii) $1.0 billion aggregate principal amount of the Company's 5.400% Senior Notes due 2036 (the "2036 Notes," and, together with the 2029 Notes, the "Notes").

The Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Subsidiary Guarantors (the "Guarantees," and, together with the Notes, the "Securities") so long as such Subsidiary Guarantors satisfy certain conditions. The Securities were issued pursuant to the Indenture, dated as of April 6, 2022 (the "Base Indenture"), as supplemented by that certain Twelfth Supplemental Indenture, dated as of November 12, 2025 (the "Twelfth Supplemental Indenture," and, together with the Base Indenture, the "Indenture"), among the Company, the Subsidiary Guarantors and U.S. Bank Trust Company, National Association, as trustee (the "Trustee").

The Company expects to use a portion of the net proceeds from the Offering to redeem the 6.875% Senior Notes due 2029 (the "6.875% 2029 Notes") issued by Targa Resources Partners LP and to use the remaining net proceeds for general corporate purposes, including to repay borrowings under the Company's unsecured commercial paper note program, to repay other indebtedness, to repurchase or redeem securities or to fund capital expenditures, additions to working capital or investments in its subsidiaries.

The Offering was registered under the Securities Act of 1933, as amended (the "Securities Act"), pursuant to a shelf registration statement on Form S-3ASR (File No. 333-286012) of the Company (as may be amended from time to time, the "Registration Statement"), as supplemented by the Prospectus Supplement, dated November 6, 2025, relating to the Securities (the "Prospectus Supplement"), filed with the U.S. Securities and Exchange Commission on November 10, 2025. A legal opinion related to the Securities is included as Exhibit 5.1 hereto.

The terms of the Securities and the Indenture are further described in the Registration Statement and the Prospectus Supplement under the captions "Description of Debt Securities" and "Description of the Notes," respectively. Such descriptions do not purport to be complete and are qualified in their entirety by reference to the Base Indenture and the Twelfth Supplemental Indenture, copies of which are filed as Exhibit 4.1 and Exhibit 4.2, respectively, to this Current Report on Form 8-K and incorporated herein by reference.

The Trustee and certain of its affiliates have from time to time performed, and may in the future perform, various financial advisory, commercial and investment banking services for the Company or the Subsidiary Guarantors for which they received or will receive customary fees and expenses. U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the Trustee under the Indenture.

NOW, THEREFORE, the Issuer, the Subsidiary Guarantors and the Trustee hereby agree that the following provisions shall supplement the Base Indenture:

**ARTICLE I** 

**DEFINITIONS** 

Section 1.1 <u>Generally</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Capitalized terms used herein and not otherwise defined herein shall have the respective meanings ascribed thereto in the Base Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The rules of interpretation set forth in the Base Indenture shall be applied hereto as if set forth in full herein.

------

Section 1.2 <u>Definition of Certain Terms</u>.

For all purposes of this Twelfth Supplemental Indenture, except as otherwise expressly provided or unless the context otherwise requires, the following terms shall have the following respective meanings:

"**<u>2029 Interest Payment Dates</u>**" shall have the meaning assigned to such term in Section 2.2(a).

"**<u>2036 Interest Payment Dates</u>**" shall have the meaning assigned to such term in Section 2.2(b).

"**<u>2029 Notes Par Call Date</u>**" means December 15, 2028.

"**<u>2036 Notes Par Call Date</u>**" means April 30, 2036.

"**<u>Book-Entry Notes</u>**" shall have the meaning assigned to such term in Section 2.1.

"**<u>Original 2029 Notes</u>**" shall have the meaning assigned to such term in Section 2.2(a).

"**<u>Original 2036 Notes</u>**" shall have the meaning assigned to such term in Section 2.2(b).

"**<u>Par Call Date</u>**" means, with respect to the 2029 Notes and the 2036 Notes, the 2029 Notes Par Call Date and the 2036 Notes Par Call Date, respectively.

"**<u>Treasury Rate</u>**" means, with respect to any Redemption Date, the yield determined by the Issuer in accordance with the following two paragraphs:

The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily)—H.15" (or any successor designation or publication) ("**<u>H.15</u>**") under the caption "U.S. government securities–Treasury constant maturities–Nominal" (or any successor caption or heading) ("**<u>H.15 TCM</u>**"). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the applicable Par Call Date with respect to the Notes to be redeemed (the "**<u>Remaining Life</u>**"); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the applicable Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

------

If on the third Business Day preceding the Redemption Date H.15 TCM or any successor designation or publication is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the applicable Par Call Date, as applicable. If there is no United States Treasury security maturing on the applicable Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the applicable Par Call Date and one with a maturity date following the applicable Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

**ARTICLE II** 

**GENERAL TERMS OF THE NOTES** 

Section 2.1 <u>Form</u>.

The 2029 Notes and the 2036 Notes and the Trustee's certificates of authentication shall be substantially in the form of Exhibit A-1 and Exhibit A-2, respectively, to this Twelfth Supplemental Indenture, which are hereby incorporated into this Twelfth Supplemental Indenture. The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Twelfth Supplemental Indenture and, to the extent applicable, the Issuer, the Subsidiary Guarantors and the Trustee, by their execution and delivery of this Twelfth Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby.

[REVERSE OF SECURITY]

**TARGA RESOURCES CORP.** 

**<u>4.350% SENIOR NOTES DUE 2029</u>**

This Security is one of a duly authorized issue of debentures, notes or other evidences of indebtedness of the Issuer (the "**Debt Securities**") of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture, to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer, the Subsidiary Guarantors and the Holders of the Debt Securities. The Debt Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as provided in the Indenture. This Security is one of a series designated as the 4.350% Senior Notes due 2029 of the Issuer, in an initial aggregate principal amount of $750,000,000 (the "**Securities**" and each a "**Security**").

1. *Interest*.

The Issuer promises to pay interest on the principal amount of this Security at the rate of 4.350% per annum.

The Issuer will pay interest semi-annually on January 15 and July 15 of each year (each such date, an "**Interest Payment Date**"), commencing January 15, 2026. Interest on the Securities will accrue from the most recent date to which interest has been paid, or, if no interest has been paid on the Securities, from November 12, 2025. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Issuer shall pay interest (including post-petition interest in any proceeding under any applicable bankruptcy laws) on overdue installments of interest (without regard to any applicable grace period) and on overdue principal and premium, if any, from time to time on demand at the same rate per annum, in each case to the extent lawful.

If any payment date with respect to the Notes falls on a day that is not a Business Day, the payment will be made on the next Business Day, and no interest will accrue on the amount of interest due on that payment date for the period from and after the Interest Payment Date, maturity date, or Redemption Date to the date of payment.

2. *Method of Payment*.

Except as provided in the Indenture, the Issuer shall pay interest on the Securities to the persons who are the registered Holders at the close of business on the Regular Record Date immediately preceding the Interest Payment Date. The Issuer shall pay principal, premium, if any, and interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for payment of public and private debts. Payments in respect of a Global Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depositary. Payments in respect of Securities in definitive form (including principal, premium, if any, and interest) will be made

A-1-4

------

at the office or agency of the Issuer maintained for such purpose at the Corporate Trust Office of the Trustee, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders on the relevant record date at their addresses set forth in the register of Holders maintained by the Registrar or at the option of the Holder, payment of interest on Securities in definitive form will be made by wire transfer of immediately available funds to any account maintained in the United States, provided such Holder has requested such method of payment and provided timely wire transfer instructions to the Paying Agent. The Holder must surrender this Security to a Paying Agent to collect payment of principal.

3. *Paying Agent and Registrar*.

Initially, U.S. Bank Trust Company, National Association will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar at any time upon notice to the Trustee and the Holders. The Issuer may act as Paying Agent.

4. *Indenture*.

This Security is one of a duly authorized issue of Debt Securities of the Issuer issued and to be issued in one or more series under the Indenture.

Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Base Indenture, those made part of the Indenture by reference to the TIA, as in effect on the date of the Base Indenture, and those terms stated in the Twelfth Supplemental Indenture. The Securities are subject to all such terms, and Holders of Securities are referred to the Base Indenture, the Twelfth Supplemental Indenture and the TIA for a statement of them. The Securities of this series are general unsecured obligations of the Issuer initially issued in an aggregate principal amount of $750,000,000; *provided, however*, that the authorized aggregate principal amount of such series may be increased from time to time as provided in the Twelfth Supplemental Indenture.

5. *Optional Redemption*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Prior to the 2029 Notes Par Call Date, the Issuer may redeem the Securities at its option, in whole or in part, at any time and from time to time, at a redemption price equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) (A) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities matured on the 2029 Notes Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (B) interest accrued to the Redemption Date; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) 100% of the principal amount of the Securities to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

A-1-5

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) On or after the 2029 Notes Par Call Date, the Issuer may redeem the Securities, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The redemption prices set forth above are subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date.

6. *Mandatory Redemption.*

The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities or to repurchase them at the option of the Holders.

7. *Denominations; Transfer; Exchange*.

The Securities are to be issued in registered form, without coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange, Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

8. *Person Deemed Owners*.

The registered Holder of a Security may be treated as the owner of it for all purposes.

9. *Amendment; Supplement; Waiver*.

Subject to certain exceptions, the Indenture may be amended or supplemented, and any existing Event of Default or compliance with any provision may be waived, with the consent of the Holders of a majority in principal amount of the then outstanding notes of the affected series. Without consent of any Holder of a Security, the parties thereto may amend or supplement the Indenture to, among other things, cure any ambiguity or omission, to correct any defect or inconsistency, or to make any other change that does not adversely affect the rights of any Holder of a Security. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution herefor, regardless of whether any notation thereof is made upon this Security or such other Securities.

10. *Defaults and Remedies*.

Certain events of bankruptcy or insolvency with respect to the Issuer are Events of Default that will result in the principal amount of the Securities, together with any accrued and unpaid interest thereon, becoming due and payable immediately upon the occurrence of such Events of Default. If any other Event of Default with respect to the Securities occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities then outstanding may declare the principal amount of all the Securities, together with any accrued and unpaid interest thereon, to be due and payable

A-1-6

------

immediately in the manner and with the effect provided in the Indenture. Notwithstanding the preceding sentence, however, if at any time after such a declaration of acceleration has been made, the Holders of a majority in principal amount of the outstanding Securities, by written notice to the Trustee, may rescind such declaration and annul its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and if all existing Events of Default with respect to the Securities, other than the nonpayment of the principal, premium, if any, or interest which has become due solely by such declaration acceleration, shall have been cured or shall have been waived. No such rescission shall affect any subsequent default or shall impair any right consequent thereon. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity or security satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power.

11. *Trustee Dealings with Issuer*.

The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuer or its Affiliates, and may otherwise deal with the Issuer or its Affiliates as if it were not the Trustee.

12. *Authentication*.

This Security shall not be valid until the Trustee signs the certificate of authentication on the other side of this Security.

13. *Abbreviations and Defined Terms*.

Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (tenant in common), TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A (Uniform Gifts to Minors Act).

**TARGA RESOURCES CORP.** 

**<u>5.400% SENIOR NOTES DUE 2036</u>**

This Security is one of a duly authorized issue of debentures, notes or other evidences of indebtedness of the Issuer (the "**Debt Securities**") of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture, to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer, the Subsidiary Guarantors and the Holders of the Debt Securities. The Debt Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as provided in the Indenture. This Security is one of a series designated as the 5.400% Senior Notes due 2036 of the Issuer, in an initial aggregate principal amount of $1,000,000,000 (the "**Securities**" and each a "**Security**").

1. *Interest*.

The Issuer promises to pay interest on the principal amount of this Security at the rate of 5.400% per annum.

The Issuer will pay interest semi-annually on January 30 and July 30 of each year (each such date, an "**Interest Payment Date**"), commencing January 30, 2026. Interest on the Securities will accrue from the most recent date to which interest has been paid, or, if no interest has been paid on the Securities, from November 12, 2025. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Issuer shall pay interest (including post-petition interest in any proceeding under any applicable bankruptcy laws) on overdue installments of interest (without regard to any applicable grace period) and on overdue principal and premium, if any, from time to time on demand at the same rate per annum, in each case to the extent lawful.

If any payment date with respect to the Notes falls on a day that is not a Business Day, the payment will be made on the next Business Day, and no interest will accrue on the amount of interest due on that payment date for the period from and after the Interest Payment Date, maturity date, or Redemption Date to the date of payment.

2. *Method of Payment*.

Except as provided in the Indenture, the Issuer shall pay interest on the Securities to the persons who are the registered Holders at the close of business on the Regular Record Date immediately preceding the Interest Payment Date. The Issuer shall pay principal, premium, if any, and interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for payment of public and private debts. Payments in respect of a Global Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depositary. Payments in respect of Securities in definitive form (including principal, premium, if any, and interest) will be made

A-2-4

------

at the office or agency of the Issuer maintained for such purpose at the Corporate Trust Office of the Trustee, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders on the relevant record date at their addresses set forth in the register of Holders maintained by the Registrar or at the option of the Holder, payment of interest on Securities in definitive form will be made by wire transfer of immediately available funds to any account maintained in the United States, provided such Holder has requested such method of payment and provided timely wire transfer instructions to the Paying Agent. The Holder must surrender this Security to a Paying Agent to collect payment of principal.

3. *Paying Agent and Registrar*.

Initially, U.S. Bank Trust Company, National Association will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar at any time upon notice to the Trustee and the Holders. The Issuer may act as Paying Agent.

4. *Indenture*.

This Security is one of a duly authorized issue of Debt Securities of the Issuer issued and to be issued in one or more series under the Indenture.

Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Base Indenture, those made part of the Indenture by reference to the TIA, as in effect on the date of the Base Indenture, and those terms stated in the Twelfth Supplemental Indenture. The Securities are subject to all such terms, and Holders of Securities are referred to the Base Indenture, the Twelfth Supplemental Indenture and the TIA for a statement of them. The Securities of this series are general unsecured obligations of the Issuer initially issued in an aggregate principal amount of $1,000,000,000; *provided, however*, that the authorized aggregate principal amount of such series may be increased from time to time as provided in the Twelfth Supplemental Indenture.

5. *Optional Redemption*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Prior to the 2036 Notes Par Call Date, the Issuer may redeem the Securities at its option, in whole or in part, at any time and from time to time, at a redemption price equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) (A) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities matured on the 2036 Notes Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points less (B) interest accrued to the Redemption Date; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) 100% of the principal amount of the Securities to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

A-2-5

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) On or after the 2036 Notes Par Call Date, the Issuer may redeem the Securities, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The redemption prices set forth above are subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date.

6. *Mandatory Redemption.*

The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities or to repurchase them at the option of the Holders.

7. *Denominations; Transfer; Exchange*.

The Securities are to be issued in registered form, without coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange, Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

8. *Person Deemed Owners*.

The registered Holder of a Security may be treated as the owner of it for all purposes.

9. *Amendment; Supplement; Waiver*.

Subject to certain exceptions, the Indenture may be amended or supplemented, and any existing Event of Default or compliance with any provision may be waived, with the consent of the Holders of a majority in principal amount of the then outstanding notes of the affected series. Without consent of any Holder of a Security, the parties thereto may amend or supplement the Indenture to, among other things, cure any ambiguity or omission, to correct any defect or inconsistency, or to make any other change that does not adversely affect the rights of any Holder of a Security. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution herefor, regardless of whether any notation thereof is made upon this Security or such other Securities.

10. *Defaults and Remedies*.

Certain events of bankruptcy or insolvency with respect to the Issuer are Events of Default that will result in the principal amount of the Securities, together with any accrued and unpaid interest thereon, becoming due and payable immediately upon the occurrence of such Events of Default. If any other Event of Default with respect to the Securities occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities then outstanding may declare the principal amount of all the Securities, together with any accrued and unpaid interest thereon, to be due and payable

A-2-6

------

immediately in the manner and with the effect provided in the Indenture. Notwithstanding the preceding sentence, however, if at any time after such a declaration of acceleration has been made, the Holders of a majority in principal amount of the outstanding Securities, by written notice to the Trustee, may rescind such declaration and annul its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and if all existing Events of Default with respect to the Securities, other than the nonpayment of the principal, premium, if any, or interest which has become due solely by such declaration acceleration, shall have been cured or shall have been waived. No such rescission shall affect any subsequent default or shall impair any right consequent thereon. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity or security satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power.

11. *Trustee Dealings with Issuer*.

The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuer or its Affiliates, and may otherwise deal with the Issuer or its Affiliates as if it were not the Trustee.

12. *Authentication*.

This Security shall not be valid until the Trustee signs the certificate of authentication on the other side of this Security.

13. *Abbreviations and Defined Terms*.

Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (tenant in common), TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A (Uniform Gifts to Minors Act).

14. *CUSIP Numbers*.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such number as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

15. *Absolute Obligation*.

No reference herein to the Indenture and no provision of this Security or the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security in the manner, at the respective times, at the rate and in the coin or currency herein prescribed.

Re: Registration Statement No. 333-286012

Ladies and Gentlemen:

We have acted as counsel to Targa Resources Corp., a Delaware corporation (the "***Company***"), and the subsidiary guarantors set forth on Schedule I hereto (the "***Subsidiary Guarantors***") with respect to certain legal matters in connection with the issuance by the Company of $750,000,000 aggregate principal amount of its 4.350% Senior Notes due 2029 (the "***2029 Notes***"), and of $1,000,000,000 aggregate principal amount of its 5.400% Senior Notes due 2036 (the "***2036 Notes***," and, together with the 2029 Notes, the "***Notes***") and the guarantee of the Notes (the "***Guarantee***," and, together with the Notes, the "***Securities***") by the Subsidiary Guarantors, under the Indenture dated as of April 6, 2022 (the "***Base Indenture***"), by and among the Company, the Subsidiary Guarantors and U.S. Bank Trust Company, National Association, as trustee (the "***Trustee***"), as supplemented by the Twelfth Supplemental Indenture, dated as of November 12, 2025, setting forth the terms of the Notes (the "***Twelfth Supplemental Indenture***," and, together with the Base Indenture as so supplemented, the "***Indenture***"), and pursuant to a registration statement on Form S-3 under the Securities Act of 1933, as amended (the "***Act***"), which became automatically effective upon filing with the U.S. Securities and Exchange Commission (the "***Commission***") on March 21, 2025 (Registration No. 333-286012) (as may be amended and supplemented from time to time, the "***Registration Statement***"). This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus, other than as expressly stated herein with respect to the issuance of the Securities.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of the Company and the Subsidiary Guarantors, as applicable, and others as to factual matters without having independently verified such factual matters. We are opining herein as to (i) the internal laws of the State of New York and (ii) the Delaware General Corporation Law, the Delaware Revised Uniform Limited Partnership Act and the Delaware Limited Liability Company Act (including, in each case, the applicable provisions of the Delaware Constitution and the reported judicial decisions interpreting such laws), and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or, in the case of Delaware, any other laws, or as to any matters of municipal law or the laws of any local agencies within any state.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof, when the Securities have been duly executed, issued, and authenticated in accordance with the terms of the Indenture and delivered against payment therefor pursuant to the underwriting agreement, dated November 6, 2025, among the Company, the Subsidiary Guarantors and BofA Securities, Inc., Citigroup Global Markets Inc., RBC Capital Markets, LLC and Truist Securities, Inc. as representatives of the several underwriters named therein, the Securities will have been duly authorized by all necessary corporate action of the Company and all necessary corporate, limited partnership or limited liability company action, as applicable, of the Subsidiary Guarantors, and will be legally valid and binding obligations of the Company and the Subsidiary Guarantors, enforceable against the Company and the Subsidiary Guarantors in accordance with their terms.

Our opinion is subject to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the effects of bankruptcy, insolvency, reorganization, preference, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the effects of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith, fair dealing and the discretion of the court before which a proceeding is brought;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the invalidity under certain circumstances under law or court decisions of provisions for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) we express no opinion with respect to (i) consents to, or restrictions upon, governing law, jurisdiction, venue, service of process, arbitration, remedies or judicial relief; (ii) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights; (iii) waivers of rights or defenses contained in Section 4.05 of the Base Indenture and waivers of broadly or vaguely stated rights; (iv) covenants not to compete; (v) provisions for exclusivity, election or cumulation of rights or remedies; (vi) provisions authorizing or validating conclusive or discretionary determinations; (vii) grants of setoff rights; (viii) provisions to the effect that a guarantor is liable as a primary obligor, and not as a surety and provisions purporting to waive modifications of any guaranteed obligation to the extent such modification constitutes a novation; (ix) provisions for the payment of attorneys' fees where such payment is contrary to law or public policy; (x) proxies, powers and trusts; (xi) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any right or property; (xii) provisions for liquidated damages, default interest, late charges, monetary penalties, prepayment or make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty; (xiii) provisions permitting, upon acceleration of any indebtedness (including the Notes), collection of that portion of the stated principal amount thereof that might be determined to constitute unearned interest thereon; and (xiv) the severability, if invalid, of provisions to the foregoing effect.

With your consent, we have assumed (a) that the Indenture and the Securities (collectively, the "***Documents***") have been duly authorized, executed and delivered by the parties thereto, other than the Company and the Subsidiary Guarantors, (b) that the Documents constitute legally valid and binding obligations of the parties thereto other than the Company and the Subsidiary Guarantors, enforceable against each of them in accordance with their respective terms, and (c) that the status of the Documents as legally valid and binding obligations of the parties is not affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders, or (iii) failures to obtain required consents, approvals or authorizations from, or make required registrations, declarations or filings with, governmental authorities.

This opinion is for your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act.
