On March 3, 2026, Jacobs Solutions Inc. (the "Company") completed the previously announced offering (the "Offering") of $800,000,000 aggregate principal amount of its 4.750% Senior Notes due 2031 (the "2031 Notes") and $500,000,000 aggregate principal amount of its 5.375% Senior Notes due 2036 (the "2036 Notes" and, together with the 2031 Notes, the "Notes"). The Notes are fully and unconditionally guaranteed (the "Guarantees") by Jacobs Engineering Group Inc., a wholly-owned subsidiary of the Company (the "Guarantor"). The Notes and the Guarantees were offered pursuant to a prospectus supplement, dated February 24, 2026, to the prospectus dated February 2, 2026, that forms a part of the Company and the Guarantor's automatic shelf registration statement on Form S-3ASR (File Nos. 333-293127 and 333-293127-01) previously filed with the Securities and Exchange Commission.

The Company intends to use the net proceeds from the Offering to finance the cash consideration of the acquisition from shareholders of PA Consulting Group Limited ("PA Consulting") other than the Company and its affiliates (the "PA Shareholders") of all of the remaining issued share capital of PA Consulting owned by the PA Shareholders (the "Acquisition"), together with cash on hand if needed based on the final adjusted purchase price of the Acquisition. Pending completion of the Acquisition, the Company intends to use the net proceeds from the Offering to repay amounts outstanding under its revolving credit facility and term loan facility, and upon consummation of the Acquisition, finance the cash consideration of the Acquisition with additional term loan borrowings, with any remaining proceeds to be used for general corporate purposes. If the Acquisition is not consummated for any reason, the Company intends to use the net proceeds from the Offering to repay amounts outstanding under its revolving credit facility and term loan facility, with any remaining proceeds to be used for general corporate purposes.

An opinion regarding the legality of the Notes and the Guarantees is filed as Exhibit 5.1 hereto, and is incorporated by reference into the Registration Statement, and the consent relating to the incorporation of such opinion is incorporated by reference into the Registration Statement and is filed as Exhibit 23.1.

The Notes and the Guarantees were issued pursuant to an indenture, dated as of February 16, 2023 (the "Base Indenture"), among the Company, the Guarantor and U.S. Bank Trust Company, National Association, as trustee (the "Trustee"), as supplemented by the third supplemental indenture, dated March 3, 2026, among the Company, the Guarantor and the Trustee (the "Third Supplemental Indenture" and, together with the Base Indenture, the "Indenture").

Interest on the Notes is payable semi-annually in arrears on each March 3 and September 3, commencing on September 3, 2026, until maturity. The 2031 Notes will bear interest at 4.750% per annum and will mature on March 3, 2031. The 2036 Notes will bear interest at 5.375% per annum and will mature on March 3, 2036.

Prior to (i) with respect to the 2031 Notes, February 3, 2031 (one month prior to the maturity date of the 2031 Notes) and (ii) with respect to the 2036 Notes, December 3, 2035 (three months prior to the maturity date of the 2036 Notes) (each such date, a "Par Call Date"), the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at the applicable redemption prices calculated by the Company (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed, assuming that such Notes matured on the Par Call Date, discounted to the redemption date on a semiannual basis (assuming a 360-day year of twelve 30-day months), at the Treasury Rate (as defined in the Third Supplemental Indenture) plus (i) with respect to the 2031 Notes, 20 basis points and (ii) with respect to the 2036 Notes, 25 basis points, less (b) interest accrued to the redemption date, and (2) 100% of the principal amount of such Notes to be redeemed, plus, in either case, accrued and unpaid interest on the Notes, if any, to, but excluding, the redemption date.

In addition, at any time and from time to time on or after the applicable Par Call Date, the Company may redeem each series of Notes, at its option, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the Notes, if any, to, but excluding, the redemption date.

The Notes are the Company's senior unsecured obligations and will rank equally in right of payment with all of the Company's existing and future senior unsecured indebtedness, rank senior in right of payment to all of the Company's future subordinated indebtedness and be subordinated to all of the Company's future secured indebtedness, if any, and liabilities of its subsidiaries that do not guarantee the Notes. The Guarantees will be the Guarantor's senior unsecured obligations and will rank equally in right of payment with all of the Guarantor's existing and future senior unsecured

------

indebtedness, rank senior in right of payment to all of the Guarantor's future subordinated indebtedness and be subordinated to all of the Guarantor's future secured indebtedness, if any, and liabilities of its subsidiaries. The Guarantees by the Guarantor will automatically and unconditionally be released, without the consent of the Trustee or the holders of the Notes, under certain circumstances, including, among other things, if the combined outstanding principal amount of the Guarantor's 5.900% Sustainability-Linked Senior Notes due 2033 and 6.350% Senior Notes due 2028 is equal to or less than $300,000,000 in the aggregate and the guarantees of the Guarantor under the Company's revolving credit facility and term loan facility are released or will be concurrently released with the Guarantees.

The Indenture contains covenants that limit the Company and the Guarantor's ability to, among other things, incur certain indebtedness secured by liens, engage in certain sale and leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all of their respective assets. Subject to certain limitations, in the event of the occurrence of both (1) a change of control and (2) a downgrade of the Notes below investment grade rating by both Moody's Investors' Services, Inc. and Standard & Poor's Ratings Services within a specified time period, the Company will be required to make an offer to purchase the Notes at a price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest to, but not including, the date of repurchase.

The foregoing description of the issuance of the Notes and the Guarantees and the terms thereof does not purport to be complete and is qualified in its entirety by reference to the Base Indenture and the Third Supplemental Indenture, attached hereto as Exhibits 4.1 and 4.2, respectively, and incorporated herein by reference. The form of Notes and the form of Guarantees, which are included as part of the Third Supplemental Indenture, are filed as Exhibits 4.3 and 4.4, and are incorporated herein by reference.

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 (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. If there is no United States Treasury security maturing on such Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from such Par Call Date, one with a maturity date preceding such Par Call Date and one with a maturity date following such Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding such Par Call Date. If there are two or more United States Treasury securities maturing

------

on such 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.

"<u>Voting Stock</u>" of any specified Person as of any date means the capital stock of such Person that is at the time entitled to vote generally in the election of the Board of Directors of such Person or Persons performing similar functions.

**ARTICLE II.** 

**THE NOTES** 

SECTION 2.01 <u>Title and Terms.</u>

There is hereby created under the Indenture two series of Debt Securities known and designated as the "4.750% Senior Notes due 2031" and "5.375% Senior Notes due 2036." The aggregate principal amount of 2031 Notes and 2036 Notes that may be authenticated and delivered under this Third Supplemental Indenture is initially limited to $800,000,000 and $500,000,000, respectively, except for Notes authenticated and delivered upon reregistration of, transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 2.07, 2.08, 2.09 or 9.04 of the Indenture.

The Guarantor fully and unconditionally guarantees, pursuant to the terms of the Guarantees contained in Article XIII of the Indenture, to each Holder of the Notes the due and punctual payment of the principal of, any premium and interest on, with respect to each series of Notes and the due, when and as the same shall become due and payable, whether at maturity, by acceleration, redemption, repayment or otherwise, in accordance with the terms of each series of Notes, this Third Supplemental Indenture and the Indenture. Following the first day that: (1) the combined outstanding principal amount of the Guarantor's 5.900% Sustainability-Linked Senior Notes due 2033 and 6.350% Senior Notes due 2028 is equal to or less than $300,000,000 in the aggregate, (2) no event of default shall have occurred and be continuing under the Indenture and no event shall have occurred or circumstances exist which, with the delivery of notice, the passage of time or both, would constitute an event of default under the Indenture and (3) the guarantees of the Guarantor under the Revolving Credit Facility and Term Loan Facility are released or will be concurrently released with the Guarantees, the Guarantees shall be automatically and unconditionally released.

The Issuer may, without notice to or the consent of the Holders of either series of Notes, issue in separate offerings additional notes having the same ranking, interest rate, maturity and other terms (except for the date of issuance and, in some cases, the price to the public and the initial interest payment date) as the applicable series of Notes. Any such additional notes, together with the Notes, will constitute a single series of Debt Securities under the Indenture; *provided* that such additional notes are fungible with the applicable series of Notes for U.S. federal income tax purposes.

------

The Stated Maturity for the 2031 Notes shall be March 3, 2031 for payment of principal of the 2031 Notes. The Stated Maturity for the 2036 Notes shall be March 3, 2036 for payment of principal of the 2036 Notes.

The 2031 Notes shall bear interest at the rate of 4.750% per annum from March 3, 2026 or the most recent interest payment date to which interest has been paid or duly provided for, payable semi-annually in arrears on March 3 and September 3 of each year (beginning September 3, 2026), to the Persons in whose names the 2031 Notes are registered at the close of business on February 18 or August 18, as the case may be, next preceding such interest payment date, until principal thereof is paid or made available for payment.

The 2036 Notes shall bear interest at the rate of 5.375% per annum from March 3, 2026 or the most recent interest payment date to which interest has been paid or duly provided for, payable semi-annually in arrears on March 3 and September 3 of each year (beginning September 3, 2026), to the Persons in whose names the 2036 Notes are registered at the close of business on February 18 or August 18, as the case may be, next preceding such interest payment date, until principal thereof is paid or made available for payment.

Interest on the Notes shall be calculated on the basis of a 360-day year comprised of twelve 30-day months. All dollar amounts resulting from this calculation will be rounded to the nearest cent.

If any interest payment date, any redemption date, the maturity date or any other date on which the principal of or premium, if any, or interest on a Note becomes due and payable falls on a day that is not a Business Day, the required payment shall be made on the next Business Day as if it were made on the date the payment was due, and no interest shall accrue on the amount so payable for the period from and after the interest payment date, redemption date, maturity date or other date, as the case may be.

Each series of Notes shall be initially issued in the form of one or more Global Securities and the depositary for the Notes shall be The Depository Trust Company, New York, New York.

Each series of Notes shall not be subject to any sinking fund.

Each series of Notes shall be in registered form without coupons and shall be issuable in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The form of each series of Notes is attached hereto as <u>Exhibit A</u> is hereby adopted, pursuant to Section 9.01(i) of the Indenture, as the form of Debt Securities that consist of the Notes.

------

SECTION 2.02 <u>Optional Redemption.</u>

Prior to (i) with respect to the 2031 Notes, February 3, 2031 and (ii) with respect to the 2036 Notes, December 3, 2035 (each such date, a "<u>Par Call Date</u>"), the Issuer may redeem the Notes at its option, in whole or in part, at any time and from time to time, at the applicable redemption prices calculated by the Issuer (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes
being redeemed, assuming that such Notes matured on the applicable Par Call Date, discounted to the redemption date on a semiannual basis (assuming a 360-day year of twelve 30-day months), at the Treasury Rate plus (i) with respect to the 2031 Notes, 20 basis points and (ii) with respect to the 2036 Notes, 25 basis points, less (b) interest accrued to the
redemption date, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest on
the Notes, if any, to, but excluding, the redemption date.

At any time and from time to time on and after the applicable Par Call Date, the Issuer may redeem each series of Notes, at its option, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest on the Notes, if any, to, but excluding, the redemption date.

The Issuer's actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any such optional redemption shall be mailed or sent at least 10 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed. If the Issuer redeems less than all the Notes, the Trustee shall select the Notes to be redeemed, in the case of the Notes in the form of a Global Security, in accordance with the Depositary's Applicable Procedures, and in the case of any Notes in definitive form, by such method as the Trustee deems fair and appropriate. The Trustee may select for partial redemption Notes and portions of Notes in amounts equal to $2,000 or any integral multiple of $1,000 in excess thereof.

Unless the Issuer defaults in payment of the redemption price for Notes, on and after the applicable redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption.

SECTION 2.03 <u>Purchase upon a Change of Control Triggering Event.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Upon the occurrence of a Change of Control Triggering Event with respect to a series of Notes, unless the Issuer has exercised its right to redeem the Notes of such series in full pursuant to <u>Section</u> <u>2.02</u> of this Third Supplemental Indenture by giving irrevocable notice to the Trustee in accordance with this Third Supplemental Indenture and the Indenture, each Holder of the Notes of such series shall have the right to require the Issuer to purchase all or a portion (equal to $2,000 or whole multiples of $1,000 in excess thereof) of such Holder's Notes pursuant to the offer described below (the "<u>Change of Control Offer</u>") at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to, but excluding, the date of purchase (the "<u>Change of Control Payment</u>"), subject to the rights of Holders of such Notes on the relevant record date to receive interest due on the relevant interest payment date. If the Change of Control Payment Date (as defined below) falls on a day that is not a Business Day, the related payment of the Change of Control Payment shall be made on the next Business Day as if it were made on the date such payment was due, and no interest shall accrue on the amounts so payable for the period from and after such date to the next Business Day.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Within 30 days following the date upon which the Change of Control Triggering Event occurred with respect to the Notes of such series or, at the Issuer's option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Issuer shall be required to send, by first class mail (or with respect to any Global Security, to the extent permitted or required by the Depositary's Applicable Procedures, send electronically) a notice to each Holder of such series of Notes, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. The notice shall state, among other things, the purchase date, which, other than as may be required by applicable law, must be no earlier than 30 days nor later than 60 days after the date the notice is mailed or sent (or, in the case of a notice mailed or sent prior to the date of consummation of a Change of Control, no earlier than the date of the occurrence of the Change of Control), other than as may be required by law (the "<u>Change of Control Payment Date</u>"). The notice, if mailed or sent prior to the date of consummation of the Change of Control, shall state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) On the Change of Control Payment Date, the Issuer shall, to the extent lawful:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) accept or cause a third party to accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer's Certificate or statement signed by an Officer of the Issuer, which need not constitute an Officer's Certificate, stating the aggregate principal amount of Notes or portions of Notes being purchased.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Issuer shall not be required to make a Change of Control Offer with respect to the Notes if (i) a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Issuer and such third party purchases all the Notes properly tendered and not withdrawn under the third party's offer, (ii) a notice of redemption has been given to the Holders of all of the Notes in accordance with the terms of this Third Supplemental Indenture and the Indenture, unless and until there is a default in payment of the redemption price, or (iii) in connection with or in contemplation of any Change of Control, the Issuer has made an offer to purchase (an "<u>Alternate Offer</u>") any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Notes properly tendered in accordance with the terms of such Alternate Offer.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the purchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, this Third Supplemental Indenture or the Indenture, the Issuer shall comply with those securities laws and regulations and will not be deemed to have breached its obligations under this <u>Section</u> <u>2.03</u> by virtue of any such conflict.

**JACOBS SOLUTIONS INC.** 

Jacobs Solutions Inc., a corporation duly organized and existing under the laws of the State of Delaware (herein called the "<u>Issuer</u>," which term includes any successor Person under the Indenture hereinafter referred to) as obligor, for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of [•] DOLLARS ($[•]) on March 3, [*<u>2031 Notes</u>*: 2031][*<u>2036 Notes</u>*: 2036], and to pay interest thereon from March 3, 2026, or from the most recent interest payment date to which interest has been paid or duly provided for, semi-annually on March 3 and September 3 in each year, commencing September 3, 2026, at the rate of [*<u>2031 Notes</u>*: 4.750][*<u>2036 Notes</u>*: 5.375]% per annum until the principal hereof is paid or made available for payment. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Issuer shall also pay interest on overdue principal or installments of interest at such rate.

------

The interest so payable, and punctually paid or duly provided for, on any interest payment date will, as provided in the Indenture, be paid to the Person in whose name this Debt Security is registered at the close of business on the record date for such interest, which shall be February 18 or August 18 (whether or not a Business Day), as the case may be, next preceding such interest payment date. Any interest on this Debt Security which is payable, but is not punctually paid or duly provided for, on the dates and in the manner provided in this Debt Security and the Indenture shall forthwith cease to be payable to the Registered Holder hereof on the relevant record date, and such Defaulted Interest may be paid by the Issuer or the Guarantor to the Person in whose name this Debt Security is registered at the close of business on a special record date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to the Holder of this Debt Security not less than 10 days prior to such special record date, or may be paid by the Issuer or the Guarantor on this Debt Security in any other lawful manner not inconsistent with the requirements of any securities exchange on which this Debt Security may be listed, and upon such notice as may be required by such securities exchange, all as more fully provided in the Indenture.

As provided in the Indenture and subject to certain limitations therein set forth, payment of interest on this Debt Security shall be made at the Corporate Trust Office of the Trustee or, at the option of the Issuer or the Guarantor, by check mailed to the address of the Person entitled thereto as such address shall appear in the Debt Security Register or, at the option of the Registered Holder, by wire transfer to an account designated by the Registered Holder, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Reference is hereby made to the further provisions of this Debt Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to herein by manual or facsimile signature, this Debt Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

**[REVERSE OF GLOBAL NOTE]** 

This Debt Security is one of a duly authorized issue of securities of the Issuer (herein called the "<u>Debt Securities</u>"), fully and unconditionally guaranteed (the "<u>Guarantee</u>") as to payment of principal, premium, if any, and interest by Jacobs Engineering Group Inc., a corporation duly organized and existing under the laws of the State of Delaware (herein called the "<u>Guarantor</u>," which term includes any successor Person under the Indenture hereinafter referred to), issued and to be issued in one or more series under an Indenture, dated as of February 16, 2023 (the "<u>Base Indenture</u>") as supplemented by the Third Supplemental Indenture, dated as of March 3, 2026 (the "<u>Third Supplemental Indenture</u>" and, together with the Base Indenture, the "<u>Indenture</u>"), among the Issuer, the Guarantor and U.S. Bank Trust Company, National Association, as trustee (herein called the "<u>Trustee</u>"), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Guarantor, the Trustee and the Registered Holders of the Debt Securities and of the terms upon which the Debt Securities are, and are to be, authenticated and delivered. The Guarantor will be deemed released from all of its obligations under the Indenture and the Guarantee, and the Guarantee will terminate, without any action required on the part of the Trustee or any Holder of the Securities, upon the terms and conditions as provided in Section 2.01 of the Third Supplemental Indenture. This Debt Security is one of the series designated on the face hereof.

This Debt Security is subject to redemption upon notice mailed or sent at least 10 days but not more than 60 days prior to the redemption date to each Registered Holder. Prior to [*<u>2031 Notes</u>*: February 3, 2031][*<u>2036 Notes</u>*: December 3, 2035] (the "<u>Par Call Date</u>"), the Issuer may redeem this Debt Security at the Issuer's option, in whole or in part, at any time and from time to time, at the redemption price calculated by the Issuer (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• (a) the sum of the present values of the remaining scheduled payments of principal and interest on this Debt
Security, assuming this Debt Security matured on the Par Call Date, discounted to the redemption date on a semiannual basis (assuming a 360-day year of twelve 30-day months), at the Treasury Rate plus [ *<u>2031 Notes</u>* : 20][ *<u>2036 Notes</u>* : 25] basis points, less (b) interest accrued on this Debt Security to the redemption date, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 100% of the principal amount of this Debt Security to be redeemed,

plus, in either case, accrued and unpaid interest on this Debt Security, if any, to, but excluding, the redemption date.

At any time, and from time to time on and after the Par Call Date, the Issuer may redeem this Debt Security, at its option, in whole or in part, at a redemption price equal to 100% of the principal amount of this Debt Security to be redeemed plus accrued and unpaid interest on this Debt Security, if any, to, but excluding, the redemption date.

------

Upon the occurrence of a Change of Control Triggering Event with respect to this Debt Security, unless the Issuer has exercised its right to redeem this Debt Security in full as set forth in Section 2.02 of the Third Supplemental Indenture, by giving irrevocable notice to the Trustee in accordance with the Indenture, each Holder of this Debt Security shall have the right to require the Issuer to purchase all or a portion (equal to $2,000 or whole multiples of $1,000 in excess thereof) of such Holder's Debt Security pursuant to a Change of Control Offer, at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to, but excluding, the date of purchase (the "<u>Change of Control Payment</u>"), subject to the rights of Holders of this Debt Security on the relevant record date to receive interest due on the relevant interest payment date.

Within 30 days following the date upon which the Change of Control Triggering Event occurred with respect to this Debt Security or, at the Issuer's option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Issuer will be required to send by first class mail (or, to the extent permitted or required by the Depositary's Applicable Procedures, send electronically) a notice to each Holder of this Debt Security, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. The notice shall state, among other things, the purchase date, which, other than as may be required by applicable law, must be no earlier than 30 days nor later than 60 days after the date the notice is mailed or sent (or, in the case of a notice mailed or sent prior to the date of consummation of a Change of Control, no earlier than the date of the occurrence of the Change of Control), other than as may be required by law (the "<u>Change of Control Payment Date</u>"). The notice, if mailed or sent prior to the date of consummation of the Change of Control, shall state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, the Issuer will, to the extent lawful:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) accept or cause a third party to accept for payment all Debt Securities of this series or portions of Debt Securities of this series properly tendered pursuant to the Change of Control Offer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Debt Securities of this series or portions of Debt Securities of this series properly tendered; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) deliver or cause to be delivered to the Trustee the Debt Securities of this series properly accepted together with an Officer's Certificate or statement signed by an Officer of the Issuer, which need not constitute an Officer's Certificate, stating the aggregate principal amount of Debt Securities of this series or portions of Debt Securities of this series being purchased.

The Issuer shall not be required to make a Change of Control Offer with respect to this Debt Security if (x) a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Issuer and such third party purchases all the Debt Securities of this series properly tendered and not withdrawn under the third party's offer, (y) a notice of redemption has been given to the Holders of all of the Debt Securities of this series in accordance with the terms of the Indenture, unless and until there is a default in payment of the redemption price, or (z) in connection with or in contemplation of any Change of Control, the Issuer has made an offer to purchase (an "<u>Alternate Offer</u>") any and all Debt Securities of this series validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Debt Securities of this series properly tendered in accordance with the terms of such Alternate Offer.

------

The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the purchase of this Debt Security as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of this Debt Security or the Indenture, the Issuer shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under Section 2.03 of the Third Supplemental Indenture by virtue of any such conflict.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Debt Security or certain restrictive covenants and Events of Default with respect to this Debt Security, in each case upon compliance with certain conditions set forth in the Indenture. Such provisions shall be applicable to this Debt Security.

If an Event of Default with respect to this Debt Security shall occur and be continuing, the principal of and interest on this Debt Security may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, without notice to any Holder but with the consent of Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of each series affected by such supplemental indenture, the Issuer, the Guarantor and the Trustee at any time to enter into an indenture or supplemental indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Debt Securities of such series. The Indenture also permits, with certain exceptions as therein provided, prior to the acceleration of the maturity of the Debt Securities of any series, the Holders of specified percentages in aggregate principal amount of the Debt Securities of that series at the time Outstanding may on behalf of the Holders of all the Debt Securities of that series waive any past Default or Event of Default and its consequences for that series specified in the terms thereof. Any such consent or waiver by the Holder of this Debt Security shall be conclusive and binding upon such Holder and upon all future Holders of this Debt Security and of any Debt Security issued upon the registration of transfer hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Debt Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Debt Security shall not have the right to institute any action or proceeding at law or in equity or in bankruptcy or otherwise, upon or under or with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of Default with respect to the Debt Securities of this series and of the continuance thereof and unless the Holders of not less than 25% in aggregate principal amount of the Outstanding Debt Securities of this series shall have made written request to the Trustee to institute such action or proceeding with respect to such Event of Default in its own name as Trustee thereunder and shall have offered to the Trustee such security or indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and

------

the Trustee, for 60 days after its receipt of such notice, request and offer of security or indemnity shall have failed to institute such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee by the Holders of a majority in aggregate principal amount of the Debt Securities of this series at the time Outstanding. The foregoing shall not apply to any suit instituted by the Holder of this Debt Security for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein.

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

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Debt Security is registrable in the Debt Security Register, upon surrender of this Debt Security for registration of transfer at the office or agency of the Issuer in any Place of Payment, duly endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Issuer, the Trustee and the Registrar duly executed by the Registered Holder or the Registered Holder's attorney duly authorized in writing, and thereupon the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Debt Security or Debt Securities of authorized denominations for a like aggregate principal amount.

The Debt Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Debt Securities of this series are exchangeable in whole or in part for a like aggregate principal amount of Debt Securities of this series and of like tenor and terms of a different authorized denomination, as requested by the Holder surrendering the same.

As provided in the Indenture and subject to certain limitations therein set forth, no service charge shall be made for any such registration of transfer of Debt Securities, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto.

Prior to due presentation for registration of transfer of this Debt Security, the Issuer, the Guarantor, the Trustee, any paying agent or any Registrar may deem and treat the Person in whose name this Debt Security is registered as the absolute owner hereof for all purposes, whether or not this Debt Security shall be overdue, and none of the Issuer, the Trustee, any paying agent or any Registrar shall be affected by notice to the contrary.

An incorporator or any past, present or future director, officer, employee, controlling Person or stockholder, as such, of the Issuer or any successor shall not have any liability for any obligations of the Issuer under this Debt Security or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting this Debt Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of this Debt Security.

------

In the case of any conflict between the provisions of this Debt Security and the Indenture, the provisions of the Indenture shall control.

All terms used in this Debt Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Suite 3500,

Dallas, Texas 75201.

Ladies and Gentlemen:

In connection with the registration under the Securities Act of 1933, as amended (the "Act"), of $800,000,000 aggregate principal amount of 4.750% Senior Notes due 2031 and $500,000,000 aggregate principal amount of 5.375% Senior Notes due 2036 (the "Securities") of Jacobs Solutions Inc., a Delaware corporation (the "Company"), and guarantees thereof (the "Guarantees") by Jacobs Engineering Group Inc., a Delaware corporation and wholly-owned subsidiary of the Company (the "Guarantor"), issued pursuant to the Indenture, dated as of February 16, 2023, as amended and supplemented by the Third Supplemental Indenture, dated as of March 3, 2026 (the "Indenture"), each among the Company, the Guarantor and U.S. Bank Trust Company, National Association, as Trustee (the "Trustee"), we, as counsel to the Company and the Guarantor, have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion.

Upon the basis of such examination, it is our opinion that the Securities constitute valid and legally binding obligations of the Company and the Guarantees constitute valid and legally binding obligations of the Guarantor, subject, in each case, to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles.

In rendering the foregoing opinion, we are not passing upon, and assume no responsibility for, any disclosure in any registration statement or any related prospectus or other offering material relating to the offer and sale of the Securities or the Guarantees.

The foregoing opinion is limited to the Federal laws of the United States, the laws of the State of New York and the General Corporation Law of the State of Delaware, and we are expressing no opinion as to the effect of the laws of any other jurisdiction.

------

Jacobs Solutions Inc. <br>Jacobs Engineering Group Inc. - 2 -

We have relied as to certain factual matters on information obtained from public officials, officers of the Company and the Guarantor and other sources believed by us to be responsible, and we have assumed that the Indenture has been duly authorized, executed and delivered by the Trustee, that the Securities and the Guarantees endorsed thereon conform to the specimens thereof examined by us, that the Trustee's certificates of authentication of the Securities have been manually signed by one of the Trustee's authorized officers, and that the signatures on all documents examined by us are genuine, assumptions which we have not independently verified.

We hereby consent to the filing of this opinion as an exhibit to a Current Report on Form 8-K to be incorporated by reference into the registration statement relating to the Securities and the Guarantees and to the reference to us under the heading "Validity of Securities" in the prospectus supplement, dated February 24, 2026, relating to the Securities and the Guarantees. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act.
