The following constitutes the Schedule 13D (the “Schedule 13D” or the “Statement”) filed by the undersigned.

The class of equity securities to which this Schedule 13D relates is the Issuer’s Common Stock, par value $0.01 per share (“Common Stock”), of Akumin Inc., a corporation organized under the laws of the State of Delaware (the “Issuer”). The principal executive office of the Issuer is located at 8300 W. Sunrise Boulevard, Plantation, Florida 33322.

Each Reporting Person declares that neither the filing of this statement nor anything herein shall be construed as an admission that such person is, for the purposes of Section 13(d) or 13(g) of the Act or any other purpose, the beneficial owner of any of the securities covered by this statement.

Each Reporting Person may be deemed to be a member of a group with respect to the issuer or securities of the issuer for the purposes of Section 13(d) or 13(g) of the Act. Each Reporting Person declares that neither the filing of this statement nor anything herein shall be construed as an admission that such person is, for the purposes of Sections 13(d) or 13(g) of the Act or any other purpose, (i) acting (or has agreed or is agreeing to act together with any other person) as a partnership, limited partnership, syndicate, or other group for the purpose of acquiring, holding, or disposing of securities of the issuer or otherwise with respect to the issuer or any securities of the issuer or (ii) a member of any group with respect to the issuer or any securities of the issuer.

The information, if any, called for by Items 2-6, inclusive, of Schedule 13D with respect to any person enumerated in Instruction C of Schedule 13D and required to be included in this statement (the “Listed Persons”) is included in Appendix A hereto or otherwise herein. The information contained in Appendix A hereto and each other Item herein is incorporated by reference in answer or partial answer to this Item.

Not applicable.

The Reporting Persons filed an initial Schedule 13G on September 14, 2020, at such time as their aggregate share ownership crossed the applicable reporting threshold. The shares of Common Stock covered by this statement were originally acquired by the Reporting Persons prior to December 15, 2022, in the ordinary course of business solely for investment purposes and not for the purposes of participating in or influencing the management of the Issuer. On December 15, 2022, the Issuer, upon the recommendation of the Issuer’s Governance Committee, increased the size of the Issuer’s board of directors from eight to ten directors and appointed John R. Wagner along with one other person as directors of the Issuer, effective January 1, 2023. Mr. Wagner is a co-founder and managing partner of SCW Management. The foregoing description does not purport to be complete and is qualified in its entirety by the Issuer’s Press Release attached hereto as Exhibit 99.2 and incorporated by reference herein.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis taking into consideration various factors, including the Issuer’s business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for shares of Common Stock and the Issuer, in particular, as well as other developments and other investment opportunities. Based upon such review, the Reporting Persons will take such actions in the future as the Reporting Persons may deem appropriate in light of the circumstances existing from time to time, which may include further acquisitions of shares of Common Stock of the Issuer or disposal of some or all of the shares of Common Stock of the Issuer owned by the Reporting Persons or otherwise acquired by the Reporting Persons, either in the open market or in privately negotiated transactions.

Any open market or privately negotiated purchases or sales, acquisition recommendations or proposals or other transactions concerning the Issuer may be made at any time without prior notice. Any alternative may depend upon a variety of factors, including, without limitation, current and anticipated future trading prices of the securities, the financial condition, results of operations and prospects of the Issuer and general industry conditions, the availability, form and terms of financing, other investment and business opportunities, general stock market and economic conditions, tax considerations and other factors. Although the foregoing reflects plans and proposals presently contemplated by each Reporting Person with respect to the Issuer, the foregoing is subject to change at any time and dependent upon contingencies and assumed and speculative conditions, and there can be no assurance that any of the actions set forth above will be taken.

The Reporting Persons have in the past, and may in the future, engage in discussions with the Issuer’s management, board of directors, and/or other shareholders covering a broad range of subjects, including relative to performance, strategic direction, capital allocation, shareholder value, board composition and governance of the Issuer.

Depending upon each factor discussed above and any other factor (which may be unknown at this time) that is, or may become relevant, the Reporting Persons may consider, among other things: (a) the acquisition by the Reporting Persons of additional securities of the Issuer, the disposition of securities of the Issuer, or the exercise of convertible securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) changes in the present board of directors or management of the Issuer; (e) a material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer’s business or corporate structure; (g) changes in the Issuer’s articles of incorporation, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing any class of the Issuer’s securities to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to those enumerated above.

8

Except to the extent that the foregoing may be deemed to be a plan or proposal, none of the Reporting Persons currently has any plans or proposals that relate to or would result in any of the actions specified in clause (a) through (j) of Item 4 of Schedule 13D. Depending upon the foregoing factors and to the extent deemed advisable in light of their general investment policies, or other factors, the Reporting Persons may, at any time and from time to time, formulate other purposes, plans or proposals regarding the Issuer or the shares of Common Stock, or any other actions that could involve one or more of the types of transactions or have one or more of the results described in paragraphs (a) through (j) of Item 4 of Schedule 13D. The foregoing is subject to change at any time, and there can be no assurance that any of the Reporting Persons will take any of the actions set forth above.

The information, if any, called for by Items 2-6, inclusive, of Schedule 13D with respect to any person enumerated in Instruction C of Schedule 13D and required to be included in this statement is included in Appendix A hereto or otherwise herein. The information contained in Appendix A hereto and each other Item herein is incorporated by reference in answer or partial answer to this Item.

Each Reporting Person declares that neither the filing of this Schedule 13D nor anything herein shall be construed as an admission that such person is, for the purposes of Section 13(d) or 13(g) of the Act or any other purpose, the beneficial owner of any securities covered by this Schedule 13D.

Each Reporting Person may be deemed to be a member of a group with respect to the Issuer or securities of the Issuer for the purposes of Section 13(d) or 13(g) of the Act. Each Reporting Person declares that neither the filing of this Schedule 13D nor anything herein shall be construed as an admission that such person is, for the purposes of Section 13(d) or 13(g) of the Act or any other purpose, (i) acting (or has agreed or is agreeing to act) with any other person as a partnership, limited partnership, syndicate or other group for the purpose of acquiring, holding or disposing of securities of the Issuer or otherwise with respect to the Issuer or any securities of the Issuer or (ii) a member of any syndicate or group with respect to the Issuer or any securities of the Issuer.
