Ladies and Gentlemen:

CMS Energy Corporation, a Michigan corporation (the “Company”), proposes to issue and sell to the several Underwriters (as defined in Section 12 hereof) an aggregate of $400,000,000 in principal amount of its 3.75% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2050 (the “Securities”), subject to the terms and conditions set forth herein. The Underwriters have designated the Representatives (as defined in Section 12 hereof) to execute this Agreement on their behalf and to act for them in the manner provided in this Agreement. The Securities are to be issued pursuant to the provisions of the Indenture dated as of June 1, 1997 between the Company and The Bank of New York Mellon (formerly known as The Bank of New York), as trustee (the “Trustee”), as supplemented and amended by various supplemental indentures and as to be supplemented by the Tenth Supplemental Indenture, to be dated as of November 25, 2020 (the “Supplemental Indenture”), establishing the terms of the Securities (as so supplemented, the “Indenture”).

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”), in accordance with the provisions of the Securities Act of 1933, as amended (the “Act”), a registration statement on Form S-3 (Registration No. 333-236742), including a prospectus relating to the Securities, and such registration statement has become effective under the Act. The registration statement, at the time it became effective or, if any post-effective amendment thereto has been filed with the Commission, at the time the most recent post-effective amendment thereto became effective, and as it may have been thereafter amended to the date of this Agreement (including the documents then incorporated by reference therein), is herein referred to as the “Registration Statement”. The Registration Statement at the time it originally became effective is referred to hereinafter as the “Original Registration Statement”. If the Company has filed, or will file, an abbreviated registration statement to register additional Securities pursuant to Rule 462(b) under the Act (the “Rule 462(b) Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462(b) Registration Statement. The prospectus forming a part of the Registration Statement at the time the Registration Statement became effective (including the documents then incorporated by reference therein) is herein referred to as the “Basic Prospectus”; provided, that, in the event that the Basic Prospectus shall have been amended or revised prior to the execution of this Agreement, or if the Company shall have supplemented the Basic Prospectus by filing any documents pursuant to Section 13, 14 or 15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after the time the Registration Statement became effective and prior to the execution of this Agreement, which documents are deemed to be incorporated in the Basic Prospectus, the term “Basic Prospectus” shall also mean such prospectus as so amended, revised or supplemented. The Basic Prospectus, as amended and supplemented immediately prior to the time when sales of the Securities were first made or such other time as agreed by the Company and the Representatives (the “Time of Sale”), is hereinafter referred to, together with any issuer free writing prospectus (as defined in Rule 433 under the Act) relating to the Securities (each, an “Issuer Free Writing Prospectus”) and other documents listed in Schedule III hereto under the heading “Information Constituting Part of the Time of Sale Prospectus”, as the “Time of Sale Prospectus”. The Basic Prospectus, as amended and supplemented immediately prior to the Time of Sale, is hereinafter referred to as the “Preliminary Prospectus”. The Basic Prospectus, as it shall be revised or supplemented to reflect the final terms of the offering and sale of the Securities by a prospectus supplement relating to the Securities, and in the form to be filed with the Commission pursuant to Rule 424 under the Act, is hereinafter referred to as the “Prospectus”. Any reference herein to the terms “amend”, “amendment” or “supplement” with respect to the Registration Statement, the Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus shall be deemed to include amendments or supplements to the Registration Statement, the Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus, as the case may be, including any post-effective amendment to the Registration Statement and any prospectus supplement forming a part of the Prospectus relating to the Securities filed with the Commission pursuant to Rule 424(b) under the Act, and documents incorporated by reference therein or deemed to be a part of and included therein, after the date of this Agreement and prior to the termination of the offering of the Securities by the Underwriters.

(c) The Company has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Michigan and has all requisite authority to own or lease its properties and conduct its business as described in the Time of Sale Prospectus and the Prospectus and to consummate the transactions contemplated hereby, and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business as described in the Time of Sale Prospectus and the Prospectus or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on the Company and its subsidiaries taken as a whole (a “Material Adverse Effect”).

The Securities will conform in all material respects to the descriptions thereof in the Time of Sale Prospectus and the Prospectus and such descriptions conform in all material respects to the rights set forth in the instruments defining the same.

The issuance of the Securities is not subject to any preemptive or other similar rights of any securityholder of the Company or any of its subsidiaries.

(v) The Registration Statement is an automatic shelf registration statement (as defined for purposes of this Section 5(v) in Rule 405 under the Act) and initially became effective not earlier than the date that is three years prior to the Time of Purchase. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) under the Act objecting to the use of the automatic shelf registration statement form, and the Securities have been and remain eligible for registration by the Company on an automatic shelf registration statement form.

(w) The Company has implemented and maintains in effect policies, procedures and/or practices designed to ensure, in its reasonable judgment, compliance in all material respects by the Company, its subsidiaries and their respective directors, officers, employees and agents with (i) all laws, rules and regulations of any jurisdiction applicable to the Company or any of its subsidiaries from time to time concerning or relating to bribery or corruption (“Anti-Corruption Laws”) and (ii) all applicable economic or financial sanctions or trade embargoes imposed, administered or enforced from time to time by (A) the U.S. government, including those administered by the Office of Foreign Assets Control of the U.S. Department of Treasury (“OFAC”) or the U.S. Department of State, or (B) the United Nations Security Council, the European Union, any European Union member state or Her Majesty’s Treasury of the United Kingdom (collectively, “Sanctions”). The Company, its subsidiaries and their respective officers and employees, and, to the knowledge of the Company, its directors and agents, are in compliance with Anti-Corruption Laws and applicable Sanctions in all material respects. None of the Company, any of its subsidiaries or, to the knowledge of the Company or any such subsidiary, any of their respective directors, officers or employees, is (1) a person or entity listed in any Sanctions-related list of designated persons or entities maintained by OFAC, the U.S. Department of State, the United Nations Security Council, the European Union or any European Union member state, (2) a person or entity operating, organized or resident in a country, region or territory that is itself the subject or target of any Sanctions (at the time of this Agreement, Crimea, Cuba, Iran, North Korea, Sudan and Syria) (each, a “Sanctioned Country”) or (3) a person or entity owned or controlled by any such person or persons or entity or entities described in the foregoing clause (1) or clause (2) (each, a “Sanctioned Person”). No transaction contemplated by this Agreement will violate any Anti-Corruption Law or applicable Sanctions.

Notwithstanding the foregoing, the Company’s and its subsidiaries’ provision of utility services in the ordinary course of business in accordance with applicable law, including Anti-Corruption Laws and applicable Sanctions, shall not constitute a violation of this Section 5(y).

The Company and its subsidiaries have not been notified of, and have no knowledge of any event or condition that would reasonably be expected to result in, any security breach or other compromise to their IT Systems and Data, except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company and its subsidiaries are presently in compliance with all applicable laws and statutes, all judgments, orders, rules and regulations of any court or arbitrator or governmental or regulatory authority, all internal policies and all contractual obligations relating to the privacy and security of IT Systems and Data and to the protection of such IT Systems and Data from unauthorized use, access, misappropriation or modification, except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

The Company and its subsidiaries have policies and procedures in place designed to ensure the integrity and security of the IT Systems and Data and comply with such policies and procedures in all material respects.

6. Free Writing Prospectuses.

(a) The Company represents, warrants, covenants and agrees that, without the prior consent of the Representatives, it has not made and will not make any offer relating to the Securities that would constitute a free writing prospectus (as defined in Rule 405 under the Act), other than the Final Term Sheet. Each Underwriter represents, warrants, covenants and agrees, severally and not jointly, that, without the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or other free writing prospectus (as defined in Rule 405 under the Act) that would be required to be filed by the Company with the Commission or retained by the Company under Rule 433 under the Act, other than the Final Term Sheet; provided, that the prior consent of the parties hereto shall be deemed to have been given in respect of any free writing prospectus (as defined in Rule 405 under the Act) included in Schedule III hereto. Each Underwriter further covenants and agrees, severally and not jointly, that it will not (and will not permit anyone on its behalf to) use or refer to any free writing prospectus (as defined in Rule 405 under the Act) used or referenced by such Underwriter in a manner reasonably designed to lead to its broad unrestricted dissemination; provided, that such covenant and agreement shall not apply to any such free writing prospectus identified in Schedule III hereto or any such free writing prospectus prepared, authorized or approved by the Company for broad unrestricted dissemination. Any such free writing prospectus, the use of which has been consented to by the Company and the Representatives (including those listed on Schedule III hereto), is hereinafter referred to as a “Permitted Free Writing Prospectus”. For the purposes of clarity, nothing in this Section 6(a) shall restrict the Company from making any filings required in order to comply with its reporting obligations under the Exchange Act or the rules and regulations of the Commission promulgated thereunder.

(b) The Company represents and warrants that it has treated or covenants and agrees that it will treat each Permitted Free Writing Prospectus as an issuer free writing prospectus (as defined in Rule 433 under the Act) and has complied and will comply with the requirements of Rule 164 and Rule 433 under the Act applicable to any Permitted Free Writing Prospectus, including, without limitation, timely Commission filing where required, legending and record keeping.

(c) The Company covenants and agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would (i) conflict with the information in the Registration Statement, the Time of Sale Prospectus or the Prospectus or (ii) when read together with the other information that is part of the Time of Sale Prospectus, include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Representatives and, if requested by the Representatives, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document that will correct such conflict, statement or omission.

7. Indemnification.

(a) The Company agrees, to the extent permitted by law, to indemnify and hold harmless each of the Underwriters, and each person, if any, who controls any such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act or otherwise, and to reimburse the Underwriters and such controlling person or persons, if any, for any legal or other expenses incurred by them in connection with defending any action, suit or proceeding (including governmental investigations) as provided in Section 7(c) hereof, insofar as such losses, claims, damages, liabilities or actions, suits or proceedings (including governmental investigations) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus (if used prior to the date of the Prospectus), the Time of Sale Prospectus or the Prospectus, or, if the Prospectus shall be amended or supplemented, in the Prospectus as so amended or supplemented (if such Prospectus or such Prospectus as amended or supplemented is used after the period of time referred to in Section 4(e) hereof, it shall contain or be used with such amendments or supplements as the Company deems necessary to comply with Section 10(a) of the Act), the information contained in the Final Term Sheet, any Issuer Free Writing Prospectus or any issuer information (within the meaning of Rule 433 under the Act) filed or required to be filed pursuant to Rule 433(d) under the Act or arise out of or are based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or actions, suits or proceedings (including governmental investigations) arise out of or are based upon any such untrue statement or alleged untrue statement or omission or alleged omission that was made in such Registration Statement, Basic Prospectus, Time of Sale Prospectus or Prospectus, or in the Prospectus as so amended or supplemented, any Issuer Free Writing Prospectus or any issuer information (within the meaning of Rule 433 under the Act) filed or required to be filed pursuant to Rule 433(d) under the Act in reliance upon and in conformity with information furnished in writing to the Company through the Representatives on behalf of any Underwriter expressly for use therein.

The Company’s indemnity agreement contained in this Section 7(a), and the covenants, representations and warranties of the Company contained in this Agreement, shall remain in full force and effect regardless of any investigation made by or on behalf of any person, and shall survive the delivery of and payment for the Securities hereunder, and the indemnity agreement contained in this Section 7 shall survive any termination of this Agreement. The liabilities of the Company in this Section 7(a) are in addition to any other liabilities of the Company under this Agreement or otherwise.

(b) Each Underwriter agrees, severally and not jointly, to the extent permitted by law, to indemnify, hold harmless and reimburse the Company, its directors and such of its officers as shall have signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent and upon the same terms as the indemnity agreement of the Company set forth in Section 7(a) hereof, but only with respect to alleged untrue statements or omissions made in the Registration Statement, the Basic Prospectus, the Time of Sale Prospectus, the Prospectus, as amended or supplemented (if applicable), or any Issuer Free Writing Prospectus in reliance upon and in conformity with information furnished in writing to the Company through the Representatives on behalf of such Underwriter expressly for use therein.

The indemnity agreement on the part of each Underwriter contained in this Section 7(b) and the covenants, representations and warranties of such Underwriter contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or any other person, and shall survive the delivery of and payment for the Securities hereunder, and the indemnity agreement contained in this Section 7 shall survive any termination of this Agreement. The liabilities of each Underwriter in this Section 7(b) are in addition to any other liabilities of such Underwriter under this Agreement or otherwise. The Company acknowledges that the third paragraph, the sixth paragraph, the seventh paragraph, the first sentence of the tenth paragraph, the eleventh paragraph and the twelfth paragraph under the heading “Underwriting” in the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Registration Statement, the Basic Prospectus, the Time of Sale Prospectus, the Prospectus and any Issuer Free Writing Prospectus, as the case may be.

(c) If a claim is made or an action, suit or proceeding (including governmental investigation) is commenced or threatened against any person as to which indemnity may be sought under Section 7(a) hereof or Section 7(b) hereof, such person (the “Indemnified Person”) shall notify the person against whom such indemnity may be sought (the “Indemnifying Person”) promptly after any assertion of such claim, promptly after any threat is made to institute an action, suit or proceeding or, if such an action, suit or proceeding is commenced against such Indemnified Person, promptly after such Indemnified Person shall have been served with a summons or other first legal process, giving information as to the nature and basis of the claim. Failure to so notify the Indemnifying Person shall not, however, relieve the Indemnifying Person from any liability that it may have on account of the indemnity under Section 7(a) hereof or Section 7(b) hereof if the Indemnifying Person has not been prejudiced in any material respect by such failure. Subject to the immediately succeeding sentence, the Indemnifying Person shall assume the defense of any such litigation or proceeding, including the employment of counsel and the payment of all expenses, with such counsel being designated, subject to the immediately succeeding sentence, in writing by the Representatives in the case of parties indemnified pursuant to Section 7(b) hereof and by the Company in the case of parties indemnified pursuant to Section 7(a) hereof. Any Indemnified Person shall have the right to participate in such litigation or proceeding and 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 retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include (x) the Indemnifying Person and (y) the Indemnified Person and, in the written opinion of counsel to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to actual or likely conflicts of interest between them, in either of which cases the reasonable fees and expenses of counsel (including disbursements) for such Indemnified Person shall be reimbursed by the Indemnifying Person to the Indemnified Person. If there is a conflict as described in clause (ii) above, and the Indemnified Person(s) have participated in the litigation or proceeding utilizing separate counsel whose fees and expenses have been reimbursed by the Indemnifying Person and the Indemnified Person(s), or any of them, are found in a final judicial determination to be liable, such Indemnified Person(s) shall repay to the Indemnifying Person such fees and expenses of such separate counsel as the Indemnifying Person shall have reimbursed. It is understood that the Indemnifying Person shall not, in connection with any litigation or proceeding or related litigation or proceedings in the same jurisdiction as to which the Indemnified Person(s) are entitled to such separate representation, be liable under this Agreement for the reasonable fees and out-of-pocket expenses of more than one separate firm (together with not more than one appropriate local counsel) for all such Indemnified Persons. Subject to the next paragraph, all such fees and expenses shall be reimbursed by payment to the Indemnified Person(s) of such reasonable fees and expenses of counsel promptly after payment thereof by the Indemnified Person(s).

In furtherance of the requirement above that fees and expenses of any separate counsel for the Indemnified Person(s) shall be reasonable, the Underwriters and the Company agree that the Indemnifying Person’s obligations to pay such fees and expenses shall be conditioned upon the following:

(1) in case separate counsel is proposed to be retained by the Indemnified Person(s) pursuant to clause (ii) of the preceding paragraph, the Indemnified Person(s) shall in good faith fully consult with the Indemnifying Person in advance as to the selection of such counsel;

(2) reimbursable fees and expenses of such separate counsel shall be detailed and supported in a manner reasonably acceptable to the Indemnifying Person (but nothing herein shall be deemed to require the furnishing to the Indemnifying Person of any information, including, without limitation, computer print-outs of lawyers’ daily time entries, to the extent that, in the judgment of such counsel, furnishing such information might reasonably be expected to result in a waiver of any attorney-client privilege); and

(3) the Company and the Representatives shall cooperate in monitoring and controlling the fees and expenses of separate counsel for Indemnified Person(s) for which the Indemnifying Person is liable hereunder, and the Indemnified Person(s) shall use every reasonable effort to cause such separate counsel to minimize the duplication of activities as between themselves and counsel to the Indemnifying Person.

The Indemnifying Person shall not be liable for any settlement of any litigation or proceeding effected without the written consent of the Indemnifying Person, but, if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees, subject to the provisions of this Section 7, to indemnify the Indemnified Person from and against any loss, damage, liability or expense by reason of such settlement or judgment. The Indemnifying Person shall not, without the prior written consent of the Indemnified Person(s), effect any settlement of any pending or threatened litigation, proceeding or claim in respect of which indemnity has been properly sought by the Indemnified Person(s) hereunder, unless such settlement includes an unconditional release by the claimant of all Indemnified Persons from all liability with respect to claims that are the subject matter of such litigation, proceeding or claim and does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any Indemnified Person.

(d) If the indemnification provided for above in this Section 7 is unavailable to or insufficient to hold harmless an Indemnified Person under such Section 7 in respect of any losses, claims, damages or liabilities (or actions, suits or proceedings (including governmental investigations) in respect thereof) referred to therein, then each Indemnifying Person under this Section 7 shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Person on the one hand and the Indemnified Person on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each Indemnifying Person shall contribute to such amount paid or payable by such Indemnified Person in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of each Indemnifying Person, if any, on the one hand and the Indemnified Person on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions, suits or proceedings (including governmental investigations) in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the total discounts or commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus, bear to the aggregate public offering price of the Securities. The relative fault 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 Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters 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 Underwriters 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 above in this Section 7. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages or liabilities (or actions, suits or proceedings (including governmental proceedings) in respect thereof) referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Person in connection with investigating or defending any such actions, suits or proceedings (including governmental proceedings) or claims, provided that the provisions of this Section 7 have been complied with (in all material respects) in respect of any separate counsel for such Indemnified Person. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Underwriter hereunder. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 7 to contribute are several in proportion to their respective underwriting obligations and not joint.

The agreement with respect to contribution contained in this Section 7(d) shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or any Underwriter, and shall survive delivery of and payment for the Securities hereunder and any termination of this Agreement.

8. Substitution of Underwriters. If any Underwriter under this Agreement shall fail or refuse (otherwise than for some reason sufficient to justify, in accordance with the terms hereof, the termination of its obligations hereunder) to purchase the Securities that it had agreed to purchase at the Time of Purchase, the Representatives shall immediately notify the Company and the Representatives and the other Underwriters may, within 36 hours of the giving of such notice, determine to purchase, or to procure one or more other members of the Financial Industry Regulatory Authority, Inc. (“FINRA”) (or, if not members of the FINRA, who are foreign banks, dealers or institutions not registered under the Exchange Act and who agree in making sales to comply with the FINRA’s Conduct Rules), satisfactory to the Company, to purchase, upon the terms herein set forth, the principal amount of Securities that the defaulting Underwriter had agreed to purchase. If any non-defaulting Underwriter or Underwriters shall determine to exercise such right, the Representatives shall give written notice to the Company of such determination within 36 hours after the Company shall have received notice of any such default, and thereupon the Time of Purchase shall be postponed for such period, not exceeding three business days, as the Company shall determine. If, in the event of such a default, the Representatives shall fail to give such notice, or shall within such 36-hour period give written notice to the Company that no other Underwriter or Underwriters, or others, will exercise such right, then this Agreement may be terminated by the Company, upon like notice given to the Representatives within a further period of 36 hours. If in such case the Company shall not elect to terminate this Agreement, it shall have the right, irrespective of such default:

(a) to require such non-defaulting Underwriters to purchase and pay for the respective principal amounts of Securities that they had severally agreed to purchase hereunder, as herein above provided, and, in addition, the principal amount of Securities that the defaulting Underwriter shall have so failed to purchase up to a principal amount thereof equal to one-ninth (1/9) of the respective principal amounts of Securities that such non-defaulting Underwriters have otherwise agreed to purchase hereunder; and/or

(b) to procure one or more other members of the FINRA (or, if not members of the FINRA, who are foreign banks, dealers or institutions not registered under the Exchange Act and who agree in making sales to comply with the FINRA’s Conduct Rules) to purchase, upon the terms herein set forth, the principal amount of Securities that such defaulting Underwriter had agreed to purchase, or that portion thereof that the remaining Underwriters shall not be obligated to purchase pursuant to Section 8(a) hereof.

In the event the Company shall exercise its rights under Section 8(a) hereof and/or Section 8(b) hereof, the Company shall give written notice thereof to the Representatives within such further period of 36 hours, and thereupon the Time of Purchase shall be postponed for such period, not exceeding five business days, as the Company shall determine. In the event the Company shall be entitled to but shall not elect to exercise its rights under Section 8(a) hereof and/or Section 8(b) hereof, the Company shall be deemed to have elected to terminate this Agreement.

Any action taken by the Company under this Section 8 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. Termination by the Company under this Section 8 shall be without any liability on the part of the Company or any non-defaulting Underwriter.

In the computation of any period of 36 hours referred to in this Section 8, there shall be excluded a period of 24 hours in respect of each Saturday, Sunday or legal holiday that would otherwise be included in such period of time.

9. Effectiveness and Termination of Agreement. This Agreement shall become effective upon the execution and delivery of this Agreement by the parties hereto.

This Agreement may be terminated at any time prior to the Time of Purchase by the Representatives if, prior to such time, any of the following events shall have occurred: (i) trading in the Company’s common stock, par value $0.01 per share, shall have been suspended by the Commission or the New York Stock Exchange (“NYSE”) or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange; (ii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; (iii) any material disruption of securities settlement or clearance services; or (iv) any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity, crisis or disruption in financial markets, the effect of which on the financial markets of the United States is such as to impair, in the judgment of the Representatives, the marketability of the Securities.

If the Representatives elect to terminate this Agreement, as provided in this Section 9, the Representatives will promptly notify the Company and each other Underwriter by telephone or facsimile, confirmed by letter. If this Agreement shall not be carried out by any Underwriter for any reason permitted hereunder, or if the sale of the Securities to the Underwriters as herein contemplated shall not be carried out because the Company is not able to comply with the terms hereof, the Company shall not be under any obligation under this Agreement except as provided in Section 4(l) hereof and shall not be liable to any Underwriter or to any member of any selling group for the loss of anticipated profits from the transactions contemplated by this Agreement and the Underwriters shall be under no liability to the Company nor be under any liability under this Agreement to one another.

Notwithstanding the foregoing, the provisions of Section 4(j) hereof, Section 4(k) hereof, Section 4(l) hereof, Section 7 hereof and Section 8 hereof shall survive termination of this Agreement.

10. Notices. All notices hereunder shall, unless otherwise expressly provided, be in writing and be delivered at or mailed to the following addresses or be sent by facsimile or other electronic means as follows: (i) if to the Underwriters or the Representatives, to the Representatives at the address or number, as appropriate, designated in Schedule I hereto; and (ii) if to the Company, to CMS Energy Corporation, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: Executive Vice President and Chief Financial Officer (Facsimile 517-788-2186), or in any case to such other address as the person to be notified may have requested in writing. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

11. Parties in Interest. The agreement herein set forth has been and is made solely for the benefit of the Underwriters, the Company, the directors and the officers of the Company as shall have signed the Registration Statement and the controlling persons, if any, referred to in Section 7 hereof, and their respective successors, assigns, executors and administrators, and, except as expressly otherwise provided in Section 8 hereof, no other person shall acquire or have any right under or by virtue of this Agreement.

12. Definition of Certain Terms. The term “Underwriters”, as used herein, shall be deemed to mean the several persons, firms or corporations named in Schedule II hereto (including the Representatives herein mentioned, if so named), and the term “Representatives”, as used herein, shall be deemed to mean the representative or representatives designated by, or in the manner authorized by, the Underwriters in Schedule I hereto, which Representatives are hereby designated. If the firm or firms listed in Schedule I hereto are the same as the firm or firms listed in Schedule II hereto, then the terms “Underwriters” and “Representatives”, as used herein, shall each be deemed to refer to such firm or firms. The term “successors” as used in this Agreement shall not include any purchaser, as such purchaser, of any of the Securities from any of the respective Underwriters.

13. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

14. Counterparts. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

15. No Conflicts. The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of the Securities contemplated hereby (including in connection with determining the terms of the offering of the Securities) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person or entity. Additionally, the Underwriters are not advising the Company or any other person or entity as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction in connection with the offering of the Securities contemplated hereby. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

16. Recognition of the U.S. Special Resolution Regimes. In the event that any Underwriter that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime (as defined below), the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States. In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate (as defined below) of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights (as defined below) under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States. “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “U.S. Special Resolution Regime” means each of (x) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (y) Title II of the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

17. Execution by the Parties. This Agreement may be executed in counterparts, each of which when so executed shall be deemed to be an original and all of which when taken together shall constitute one and the same instrument. The words “execution”, “signed” and “signature” and words of like import in this Agreement or in any other certificate, agreement or document related to this Agreement (to the extent not prohibited under governing documents) shall include images of manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign and AdobeSign). The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including, without limitation, the Electronic Signatures in Global and National Commerce Act, the Michigan Uniform Electronic Transactions Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code.

If the foregoing is in accordance with your understanding, please sign and return to us counterparts hereof, and, upon the acceptance hereof by you, this letter and such acceptance hereof shall constitute a binding agreement between each of the Underwriters and the Company.

EXHIBIT A

{FORM OF OPINION OF ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, ESQ.}

The Company is a duly organized, validly existing corporation in good standing under the laws of the State of Michigan.

All legally required corporate proceedings in connection with the authorization, issuance and validity of the Securities and the sale of the Securities by the Company in accordance with the Underwriting Agreement have been taken; and no approval, authorization, consent or order of any governmental regulatory body is required with respect to the Company’s execution and delivery of, and performance of its obligations under, the Underwriting Agreement and the Indenture or is required with respect to the issuance and sale of, and the performance by the Company of its obligations under, the Securities (other than in connection with or in compliance with the provisions of the securities or blue sky laws of any state, as to which I express no opinion).

The statements made in the Time of Sale Prospectus and the Prospectus under the caption “Material United States Federal Income Tax Considerations” and “ERISA Considerations”, to the extent that such statements purport to describe matters of United States law and regulations, accurately describe such matters in all material respects.

The statements made in the Time of Sale Prospectus and the Prospectus under the captions “Description of Securities”, “Description of the Notes” and “Underwriting”, to the extent that such statements purport to describe certain provisions of the Indenture, the Securities or the Underwriting Agreement or legal matters, accurately describe such provisions or legal matters in all material respects; and the Indenture and the Securities conform in all material respects to the descriptions thereof and to the statements in regard thereto contained in such sections of the Time of Sale Prospectus and the Prospectus.

The Registration Statement was automatically effective upon filing on February 28, 2020; any required filing of each prospectus relating to the Securities (including the Prospectus) pursuant to Rule 424 under the Act has been made in compliance with and in the time periods provided by Rule 424 under the Act and all material required to be filed by the Company pursuant to Rule 433(d) under the Act has been filed with the Commission within the applicable time period prescribed for such filing by Rule 164 and Rule 433 under the Act; the Registration Statement, at the time it became effective and at the Applicable Effective Time, each of the Preliminary Prospectus and the Prospectus, at the time it was filed with the Commission pursuant to Rule 424 under the Act, and each document incorporated in each of the Preliminary Prospectus and the Prospectus as such document was originally filed pursuant to the Exchange Act (except for (i) the financial statements and schedules contained or incorporated by reference therein (including the notes thereto and the auditors’ reports thereon) or omitted therefrom and (ii) the other financial information contained or incorporated by reference therein or omitted therefrom, as to which I express no opinion), complied as to form as of their respective effective or issue dates (including, without limitation, the Applicable Effective Time) in all material respects with the Act and the Exchange Act and the applicable rules and regulations of the Commission thereunder; and at the Time of Purchase the Registration Statement is effective under the Act and, to the best of my knowledge after due inquiry, no proceedings for a stop order with respect to the Registration Statement are threatened or pending under the Act.

A-1

The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

The Indenture has been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery of the Indenture by the Trustee, will be a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally or by general principles of equity (regardless of whether enforcement is considered in a proceeding at law or in equity).

The Indenture complies as to form in all material respects with the requirements of the Trust Indenture Act and the rules and regulations of the Commission applicable to an indenture that is qualified thereunder. The Indenture is qualified under the Trust Indenture Act, and no proceedings to suspend such qualification have been instituted or, to my knowledge, threatened by the Commission.

The Securities are in the form contemplated by the Indenture, have been duly authorized, executed and delivered by the Company and, assuming the due authentication thereof by the Trustee and upon payment and delivery in accordance with the Underwriting Agreement, will constitute valid and binding obligations of the Company enforceable against the Company in accordance with their terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally or by general principles of equity (regardless of whether enforcement is considered in a proceeding at law or in equity); and the Securities are entitled to the benefits afforded by the Indenture equally and ratably with all securities presently outstanding thereunder, and no stamp taxes in respect of the original issue thereof are payable.

10.

The Company’s execution and delivery of, and performance of its obligations under, the Underwriting Agreement and the Indenture and the issuance and sale of, and the performance by the Company of its obligations under, the Securities in accordance with the terms of the Indenture and the Underwriting Agreement do not violate the provisions of the Restated Articles of Incorporation or the Amended and Restated Bylaws of the Company and will not result in a violation of any of the terms or provisions of any Applicable Laws (as defined below) or, to my knowledge, any court order to which the Company is subject or a breach of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other material agreement or instrument to which the Company is a party. For purposes hereof, the term “Applicable Laws” means those state laws of the State of Michigan and those federal laws of the United States of America that, in my experience and without independent investigation, are normally applicable to transactions of the type contemplated by the Underwriting Agreement; provided, that the term “Applicable Laws” shall not include federal or state securities or blue sky laws (including, without limitation, the Act, the Exchange Act, the Trust Indenture Act or the Investment Company Act of 1940, as amended), antifraud laws or in each case any rules or regulations thereunder or similar matters.

A-2

11.

The Company is not an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

12.

Except for the outstanding shares of preferred stock of Consumers Energy Company, all of the outstanding capital stock of each of Consumers Energy Company and CMS Enterprises Company is owned directly or indirectly by the Company, free and clear of any security interest, claim, lien or other encumbrance (except as disclosed in the Time of Sale Prospectus) or preemptive rights, and there are no outstanding rights (including, without limitation, preemptive rights), warrants or options to acquire, or instruments convertible into or exchangeable for, any shares of capital stock or other equity interest in any of Consumers Energy Company and CMS Enterprises Company or any contract, commitment, agreement, understanding or arrangement of any kind relating to the issuance of any such capital stock, any such convertible or exchangeable securities or any such rights, warrants or options.

13.

The Company has an authorized capitalization as set forth in the Time of Sale Prospectus and all of the issued shares of capital stock of the Company have been duly and validly authorized and issued and are fully paid and non-assessable.

14.

To my knowledge, there is no pending or threatened action, suit, proceeding, inquiry or investigation against the Company or any Significant Subsidiary of the Company before or brought by any person or entity that (i) is required to be disclosed in the Registration Statement, the Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus that is not disclosed or (ii) would reasonably be expected to materially and adversely affect the consummation of the transactions contemplated in the Underwriting Agreement or the performance by the Company of its obligations thereunder.

15.

Nothing has come to my attention that would lead me to believe that the Registration Statement (other than (i) the operating statistics, financial statements and schedules contained or incorporated by reference therein (including the notes thereto and the auditors’ reports thereon) or omitted therefrom and (ii) the other financial or statistical information contained or incorporated by reference therein or omitted therefrom, as to which I express no opinion or belief), at the time the Registration Statement became effective and at the Applicable Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

A-3

16.

Nothing has come to my attention that would lead me to believe that the Time of Sale Prospectus (other than (i) the operating statistics, financial statements and schedules contained or incorporated by reference therein (including the notes thereto and the auditors’ reports thereon) or omitted therefrom and (ii) the other financial or statistical information contained or incorporated by reference therein or omitted therefrom, as to which I express no opinion or belief), as of the Time of Sale, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

17.

Nothing has come to my attention that would lead me to believe that the Prospectus (other than (i) the operating statistics, financial statements and schedules contained or incorporated by reference therein (including the notes thereto and the auditors’ reports thereon) or omitted therefrom and (ii) the other financial or statistical information contained or incorporated by reference therein or omitted therefrom, as to which I express no opinion or belief), as of its date or at the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

{FORM OF LETTER OF SIDLEY AUSTIN LLP}

In acting as special counsel to the Company in connection with the transactions described in such letter, we have participated in conferences with officers and other representatives of the Company, including certain of the Company’s internal counsel, representatives of the independent public accountants for the Company and representatives of and counsel to the Underwriters, at which conferences certain contents of the Time of Sale Prospectus and the Prospectus and related matters were discussed. Although we are not passing upon or assuming responsibility for the accuracy, completeness or fairness of the statements included or incorporated by reference in or omitted from the Registration Statement, the Time of Sale Prospectus or the Prospectus and have made no independent check or verification thereof, in the course of our review and our discussions in the conferences described above, no facts have come to our attention that have caused us to believe that:

the Registration Statement, at the time it first became effective or at the Applicable Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

the Time of Sale Prospectus, as of the Time of Sale, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

the Prospectus, as of the date of the Prospectus or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

except in each case that we express no belief and make no statement with respect to (A) the financial statements and schedules and other financial or statistical data included or incorporated by reference in or omitted from the Registration Statement, the Time of Sale Prospectus or the Prospectus, (B) any trustee’s statement of eligibility on Form T-1 or (C) assessments of, and reports on, the effectiveness of internal control over financial reporting.

▇-▇-▇

▇▇▇▇▇▇▇ ▇-▇

{FORM OF OPINION OF SIDLEY AUSTIN LLP}

The statements in each of the Time of Sale Prospectus and the Prospectus under the caption “Material United States Federal Income Tax Considerations,” to the extent that such statements purport to describe matters of United States federal income tax law or legal conclusions with respect thereto, are a fair and accurate description of such matters in all material respects.
