Re:	Registration Statement on Form S-8

Ladies and Gentlemen:

We are issuing this opinion in our capacity as special legal counsel for Accelevation Holdings

Corp., a Delaware corporation (the “Company”), in connection with the Registration Statement on

Form S-8 (the “Registration Statement”) to be filed with the U.S. Securities and Exchange Commission

(the “Commission”) on or about the date hereof under the Securities Act of 1933, as amended (the “Act”),

relating to the issuance by the Company of an aggregate of up to 40,000,000 shares (the “Shares”) of the

Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), that

may be issued by the Company under the Accelevation Holdings Corp. 2026 Omnibus Incentive Plan (the

“Omnibus Plan”), including shares of Class A Common Stock that may again become available for

delivery with respect to awards under the Omnibus Plan pursuant to the share counting, share recycling

and other terms and conditions of the Omnibus Plan.

In connection therewith, we have examined originals, or copies certified or otherwise identified to

our satisfaction, of such documents, corporate records and other instruments as we have deemed

necessary for the purposes of this opinion, including: (i) the corporate and organizational documents of

the Company; (ii) minutes and records of the proceedings of the Company with respect to the Registration

Statement; (iii) the Omnibus Plan; and (iv) the Registration Statement and the exhibits thereto.

For purposes of this opinion, we have assumed the authenticity of all documents submitted to us

as originals, the conformity to the originals of all documents submitted to us as copies and the authenticity

of the originals of all documents submitted to us as copies. We have also assumed the legal capacity of all

natural persons, the genuineness of the signatures of persons signing all documents in connection with

which this opinion is rendered, the authority of such persons signing on behalf of the parties thereto (other

than the Company) and the due authorization, execution and delivery of all documents by the parties

thereto (other than the Company). As to any facts material to the opinions expressed herein that we have

not independently established or verified, we have relied upon statements and representations of the

officers and other representatives of the Company and others.

We have further assumed that at all future times relevant to this opinion the number of shares of

Class A Common Stock that the Company is authorized to issue pursuant to its Amended and Restated

Certificate of Incorporation will exceed the number of shares of Class A Common Stock outstanding and

the number of shares of Class A Common Stock that the Company is obligated to issue (or had otherwise

reserved for issuance) for any purposes by at least the number of Shares.

Accelevation Holdings Corp. October 1, 2026 Page 2

Based upon and subject to the assumptions, qualifications and limitations identified in this

opinion, we are of the opinion that the Shares have been duly authorized and, when issued, delivered and

paid for in accordance with the terms of the Omnibus Plan and the Company’s Amended and Restated

Certificate of Incorporation and Amended and Restated Bylaws, the Shares will be validly issued, fully

paid and non-assessable. 

We do not find it necessary for the purposes of this opinion, and accordingly we do not purport to

cover herein, the application of the securities or “Blue Sky” laws of the various states to the issuance and

sale of the Shares.

Our advice on every legal issue addressed in this opinion is based exclusively on the General

Corporation Law of the State of Delaware. We express no opinion as to any other law or any matter other

than as expressly set forth above, and no opinion as to any other law or matter may be inferred or implied

herefrom. The opinions expressed herein are rendered as of the date hereof, and we expressly disclaim

any obligation to update or supplement this opinion or advise you of any change in any matter after the

date hereof.

This opinion is furnished to you in connection with the filing of the Registration Statement in

accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and is not to be

used, circulated, quoted or otherwise relied upon for any other purpose.

This opinion may be filed as an exhibit to the Registration Statement. In giving this consent, we

do not thereby admit that we are in the category of persons whose consent is required under Section 7 of

the Act or the rules and regulations of the Commission.

	Sincerely,
	/s/ Kirkland & Ellis LLP
