The Securities will be issued pursuant to an Indenture to be dated as of January 16, 2025 (the “Indenture”) among the Issuers, the guarantors listed in Schedule 2 hereto (the “Guarantors”) and Wilmington Trust, National Association, as trustee (the “Trustee”), and will be guaranteed on an unsecured senior basis by each of the Guarantors (the “Guarantees”).

Copies of the Preliminary Offering Memorandum have been, and copies of the Offering Memorandum will be, delivered by the Calumet Parties to the Initial Purchasers pursuant to the terms of this Agreement. Each of the Calumet Parties hereby confirms that it has authorized the use of the Preliminary Offering Memorandum, the other Time of Sale Information and the Offering Memorandum in connection with the offering and resale of the Securities by the Initial Purchasers in the manner contemplated by this Agreement. Capitalized terms used but not defined herein shall have the respective meanings given to such terms in the Preliminary Offering Memorandum. References herein to the Preliminary Offering Memorandum, the Time of Sale Information and the Offering Memorandum shall be deemed to refer to and include all of the Incorporated Documents (as defined below).

The “Time of Sale” means 5:45 P.M. New York City Time, on the date hereof. The “Time of Sale Information” means the Preliminary Offering Memorandum together with the written communications listed on Annex A hereto.

Each of the Calumet Parties hereby jointly and severally confirms its agreement with the several Initial Purchasers concerning the purchase and resale of the Securities, as follows:

1. Purchase and Resale of the Securities.

(a) The Issuers agree to issue and sell the Securities to the several Initial Purchasers as provided in this Agreement, and each Initial Purchaser, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Issuers the respective principal amount of Securities set forth opposite such Initial Purchaser’s name in Schedule 1 hereto at a price equal to 96.75% of the principal amount thereof plus accrued interest, if any, from January 16, 2025 to the Closing Date. The Issuers will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.

The Parent maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act); such disclosure controls and procedures have been designed to provide reasonable assurance that information required to be disclosed by the Parent in reports that it submits or files under the Exchange Act is made known to the Parent’s management, including its principal executive officer and principal financial officer, to allow for timely decisions regarding required disclosure; and, except as described in or incorporated by reference into the Time of Sale Information the Offering Memorandum, such disclosure controls and procedures are effective at the reasonable assurance level.

(ee) No Legal Actions. Except as described in the Time of Sale Information and the Offering Memorandum, there is (i) no action, suit or proceeding before or by any court, arbitrator or governmental or regulatory agency, body or official, domestic or foreign, now pending or, to the knowledge of the Calumet Parties, threatened, to which any of the Calumet Entities or their respective subsidiaries is or may be a party or to which the business or property of any of the Calumet Entities

or their respective subsidiaries is or may be subject, and (ii) no injunction, restraining order or order of any nature issued by a federal or state court or foreign court of competent jurisdiction to which any of the Calumet Entities or their respective subsidiaries is or may be subject, that, in the case of clauses (i) and (ii) above, if determined adversely to any of the Calumet Entities or their respective subsidiaries, would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or materially impair the ability of any of the Calumet Parties to perform their obligations under the Transaction Documents.

(ff) Restrictions on Subsidiaries. No subsidiary of the Parent (other than the Unrestricted Subsidiaries) is currently prohibited, directly or indirectly, from paying any dividends to the Partnership, from making any other distribution on such subsidiary’s capital stock or partnership or limited liability company interests, from repaying to the Partnership any loans or advances to such subsidiary from the Partnership or from transferring any of such subsidiary’s property or assets to the Partnership or any other subsidiary of the Partnership, except (i) as described in or contemplated by the Time of Sale Information and the Offering Memorandum (exclusive of any amendment or supplement thereto), (ii) such prohibitions mandated by the laws of each such subsidiary’s state of formation and the terms of any such subsidiary’s governing instruments or (iii) where such prohibition would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(rr) Securities Law Exemptions. Assuming the accuracy of the representations and warranties of the Initial Purchasers contained in Section 1(b) (including Annex C hereto) and their compliance with their agreements set forth therein, it is not necessary, in connection with the issuance and sale of the Securities and the Guarantees to the Initial Purchasers and the offer, resale and delivery of the Securities and the Guarantees by the Initial Purchasers in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum, to register the Securities and the Guarantees under the Securities Act or to qualify the Indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

(b) Indemnification of the Partnership. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless each of the Calumet Parties, the directors and officers of the Parent, the Partnership and Calumet Finance and each person, if any, who controls the Calumet Parties within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities, joint or several, that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Initial Purchaser furnished to the Partnership in writing by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto); it being understood and agreed that the only such information consists of the following: the fourth, eighth and ninth paragraphs, and the third sentence of the sixth paragraph under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Offering Memorandum.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one

separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by the Representative and any such separate firm for the Calumet Parties, the directors and officers of the Parent, the Partnership and Calumet Finance and any control persons of the Calumet Parties shall be designated in writing by the Partnership. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Calumet Parties on the one hand and the Initial Purchasers on the other from the offering of the Securities and the Guarantees or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Calumet Parties on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Calumet Parties on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Issuers from the sale of the Securities and the Guarantees and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities and the Guarantees. The relative fault of the Calumet Parties on the one hand and the Initial Purchasers on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuers or any Guarantor or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Calumet Parties and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities and the Guarantees exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Issuers, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange, the Nasdaq Global Select Market or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Issuers or any of the Guarantors shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery, of the Securities and the Guarantees on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum.

9. Defaulting Initial Purchaser. (a) If, on the Closing Date, any Initial Purchaser defaults on its obligation to purchase the Securities and the Guarantees that it has agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Issuers on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Issuers shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities and the Guarantees of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Issuers may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Issuers or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum or in any other

document or arrangement, and the Issuers agree to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities and the Guarantees of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Issuers as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Issuers shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Issuers as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Issuers shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Calumet Parties, except that the Calumet Parties will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Calumet Parties or any non-defaulting Initial Purchaser for damages caused by its default.

10. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Calumet Parties jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and the Guarantees and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer Written Communication and the Offering Memorandum (including any amendment or supplement thereto) and the distribution thereof (including any form of electronic distribution); (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Calumet Parties’ counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in

connection with the approval of the Securities for book-entry transfer by DTC; and (ix) 50% of the cost of any aircraft chartered in connection with the road show, if any, and all other expenses incurred by the Calumet Parties in connection with such road show presentation to potential investors. It is understood, however, that, except as provided in this Section 10 and Sections 7 and 8 hereof, the Initial Purchasers will pay all of their own costs and expenses, including without limitation the fees of their counsel and any advertising expenses connected with any offers they make, and 50% of the cost of any aircraft chartered in connection with the road show.

(b) If (i) this Agreement is terminated pursuant to Section 8, (ii) the Issuers for any reason fail to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Calumet Parties jointly and severally agree to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby.

11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, officers and directors of each Initial Purchaser referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase.

12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Calumet Parties and the Initial Purchasers contained in this Agreement or made by or on behalf of the Calumet Parties or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Calumet Parties or the Initial Purchasers.

13. Certain Defined Terms. For purposes of this Agreement, (i) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (ii) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (iii) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (iv) the term “written communication” has the meaning set forth in Rule 405 under the Securities Act.

With respect to any suit, action or other proceeding relating to this Agreement, each party irrevocably (i) submits to the exclusive jurisdiction of the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in the Borough of Manhattan in New York City and (ii) waives any objections which it may have at any time to the laying of venue of any suit, action or other proceeding brought in such court, waives any claim that such suit, action or other proceeding have been brought in an inconvenient forum and further waives the right to object, with respect to such proceedings, that such court does not have jurisdiction over such party.

(d) Waiver of Jury Trial. THE PARTIES HERETO HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT TO TRIAL BY JURY IN ANY SUIT OR PROCEEDING (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR IN ANY WAY RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

(e) Counterparts. This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, telecopier, other electronic transmission (i.e., a “pdf” or “tif”), or electronic mail (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes, and which shall be effective as delivery of a manually executed counterpart thereof.

Extended Settlement

Delivery of the notes is expected to be made against payment therefor on or about January 16, 2025, which is the second business day following the date of pricing of the notes (such settlement being referred to as “T+2”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to one business day before delivery will be required, by virtue of the fact that the notes initially will settle in T+2, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.

The notes have not been registered under the Securities Act. The notes may not be offered or sold in the United States or to U.S. persons, except to qualified institutional buyers in reliance on the exemption from registration provided by Rule 144A and to certain non-U.S. persons in offshore transactions in reliance on Regulation S. You are hereby notified that sellers of the notes may be relying on the exemption from the provisions of Section 5 of the Securities Act provided by Rule 144A or Regulation S. Any sales of the notes outside the United States may only be made in accordance with applicable selling restrictions.

This material is confidential and is for your information only and is not intended to be used by anyone other than you. This information does not purport to be a complete description of the notes or the offering. Please refer to the Preliminary Offering Memorandum.

Any disclaimers or other notices that may appear below are not applicable to this communication and should be disregarded. Such disclaimers or other notices were automatically generated as a result of this communication being sent via Bloomberg email or another communication system.

No key information document (KID) as required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) or as required by the PRIIPs Regulation as it forms part of domestic UK law by virtue of the European Union (Withdrawal) Act 2018, as amended, has been prepared as the notes will not be made available to retail investors in the EEA or the United Kingdom, respectively.
