(d), (e) During the last five years, none of the Reporting Persons have (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3.

Source and Amount of Funds or Other Consideration

On June 25, 2021, the Issuer, through its wholly-owned indirect subsidiary, Akumin Corp., a Delaware corporation (the “Subsidiary”), entered into a share purchase agreement to acquire all of the issued and outstanding common stock of Thaihot Investment Company US Limited, which owns 100% of the common stock of Alliance HealthCare Services, Inc. (“Alliance”), from Thaihot Investment Co., LTD (the “Seller”). The aggregate purchase price payable to the Seller is $820,000,000 (the “Purchase Price”), subject to customary working capital and other adjustments, which will be satisfied by way of a combination of cash on hand, the issuance of 14,223,570 Common Shares to the Seller and certain financing arrangements, including the Capital Commitment (defined below) from Stonepeak Magnet. The Purchase Price is payable by the Issuer upon closing of this transaction (the “Closing”).

Also on June 25, 2021, the Issuer and the Subsidiary entered into a Series A Notes and Common Share Purchase Agreement (the “Share Purchase Agreement”) with Stonepeak Magnet, pursuant to which, upon the Closing: (i) the Issuer will issue to Stonepeak Magnet 3,500,000 Common Shares (the “Financing Common Shares”) at a price of $2.98 per Common Share (the “Issue Price”) for an aggregate amount equal to $10,430,000; (ii) Stonepeak Magnet will subscribe for a minimum of $200,000,000 and a maximum of $689,570,000 principal amount of unsecured notes of the Subsidiary (the “Series A Financing Notes”, and the initial subscription of such Series A Financing Notes at Closing, the “Initial Series A Financing Notes”), such Series A Financing Notes bearing interest at 11.0% per annum, payable quarterly in cash, with 50% due in 2032 and 50% due in 2033, provided that, subject to certain conditions, the Subsidiary will have the option for a two-year period following the Closing to satisfy the payment of interest on any Series A Financing Notes through a combination of cash and/or payment in kind in additional Series A Financing Notes, with any interest payment made in kind based on an interest rate equal to 13% per annum; and (iii) the Issuer will issue to Stonepeak Magnet such number of warrants to purchase the Issuer’s Common Shares (the “Warrants” and, together with the Common Shares and Series A Financing Notes, the “Capital Commitment”) equal to 15% of the principal amount of the Initial Series A Financing Notes, divided by the Issue Price, such Warrants having an exercise price equal to the Issue Price and an expiry term of ten years from the date of issuance.

	Schedule 13D
CUSIP No.: 01021F109		Page 8 of 11

The amount of Series A Financing Notes issued to Stonepeak is based on the amount of alternative debt financing (the “Alternative Financing”) that the Issuer completes on or prior to Closing (such Alternative Financing reducing dollar-for-dollar the Capital Commitment by Stonepeak Magnet at the time of Closing from the maximum of $689,570,000, but not less than the minimum of $200,000,000, principal amount of Series A Financing Notes). On August 9, 2021, the Issuer confirmed that it had completed $375,000,000 in Alternative Financing. As a result, Stonepeak Magnet subscribed for a $340,000,000 principal amount of Initial Series A Financing Notes and received 17,114,093 Warrants upon Closing.

Because the $340,000,000 principal amount of the Initial Series A Financing Notes is less than the maximum $689,570,000 principal amount of Financing Notes available for subscription at Closing, the unused portion will remain available to be drawn by the Subsidiary for a three-year period following the Closing, provided certain conditions are met. Any such future subscription by Stonepeak Magnet will involve a further issuance of Series A Financing Notes and Warrants, in each case, on the same terms described above; provided, however, that the number of additional Series A Financing Warrants will equal 20% of the dollar amount drawn by the Subsidiary divided by 120% of the 10-day volume weighted average price of the Common Shares ending on the trading day immediately prior to the earlier of the announcement or issuance of such Warrants (the “Growth Equity Warrant Strike Price”), and the exercise price for such additional Warrants will be equal to the Growth Equity Warrant Strike Price, subject to regulatory approval.

At any time after seven years from the issuance date of the Series A Financing Notes, the Subsidiary may redeem such Series A Financing Notes, in whole or in part, by paying in cash the principal amount and any accrued but unpaid interest, in each case, plus 5%. To the extent that the Subsidiary has not redeemed any Series A Financing Notes by the eleventh anniversary of the issuance date of such Series A Financing Notes, the Subsidiary will be required to redeem: (a) 50% of such Series A Financing Notes on the eleventh anniversary of such issuance date by paying in cash the principal amount and any accrued but unpaid interest, in each case, plus 5%; and (b) the remaining balance by the twelfth anniversary of such issuance date by paying in cash the principal amount and any accrued but unpaid interest, in each case, plus 5%.

The right of Stonepeak Magnet to acquire the Common Shares and Warrants pursuant to the Share Purchase Agreement is conditioned upon the Closing. On August 23, 2021, the Issuer notified Stonepeak Magnet that all material conditions to Closing had been met, and Closing occurred on September 1, 2021.

The Capital Commitment of $350,430,000 was funded with cash contributed to Stonepeak Magnet by the limited partners of Stonepeak Infrastructure Fund IV LP and Stonepeak Infrastructure Fund IV (Lux) SCSp, Stonepeak Magnet’s limited partners. A cash fee equal to $14,000,000 was paid in full to Stonepeak Magnet in the form of original issue discount on the Initial Series A Financing Notes, resulting in a net Capital Commitment amount of $336,430,000.

The summary contained herein of each of the Series A Financing Notes, Warrants, and Share Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Share Purchase Agreement and the form of Series A Note and forms of the Series A Warrant Certificate and Series B Warrant Certificate, each of which is filed as Exhibit 2, Exhibit 3, Exhibit 4 and Exhibit 5, respectively, to this Schedule 13D and is incorporated by reference herein.

Item 4.

Purpose of Transaction

The response to Item 3 of this Schedule 13D is incorporated by reference herein.

In connection with the Capital Commitment, Stonepeak Magnet was granted certain investor rights at Closing, including: (a) the right to nominate a single representative for election to the board of directors of the Issuer (the “Board”) for so long as Stonepeak Magnet owns Series A Financing Notes with an aggregate outstanding principal amount of at least $100,000,000, and subject to certain other conditions, including applicable securities law and stock exchange rules (the “Board Representation and Observation Rights Agreement”); (b) certain consent rights as holder of the Series A Financing Notes; and (c) customary registration rights with respect to the Financing Common Shares and the Common Shares issuable upon exercise of the Warrants (the “Registration Rights Agreement”). Mr. James Wyper, Senior Managing Director with Stonepeak Infrastructure Partners, will serve as the Board nominee of Stonepeak Magnet.

In connection with the signing of the Share Purchase Agreement, Stonepeak Magnet and the Issuer entered into various Voting Support Agreements with owners of a majority of the outstanding Common Shares eligible to vote on the matters therein (the “Majority Disinterested Shareholders”), pursuant to which the Majority Disinterested Shareholders committed to vote in favor of any required shareholder resolution approving, generally, (a) the exercise of the Warrants and (b) the appointment of Mr. Wyper to the Board.
