Item 4.	PURPOSE OF TRANSACTION.

	The Reporting Persons purchased the securities based on the Reporting Persons' belief that the securities, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of securities at prices that would make the purchase or sale of securities desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of securities on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

	On January 22, 2023, the Issuer entered into a securities purchase agreement (the "Purchase Agreement") with the Starboard Vehicles, Starboard Value and Mr. Smith (collectively, "Starboard"), pursuant to which the Issuer agreed to issue and sell to the Starboard Vehicles, in a private placement (the "PIPE Transaction") exempt from the registration requirements of the Securities Act of 1933, as amended, and the prospectus requirements of British Columbia securities law, (i) an aggregate of 485,000,000 senior preferred shares of the Issuer designated as Series A Senior Preferred Shares (the "Preferred Shares"), which Preferred Shares are convertible into the Issuer's Common Shares (such Common Shares as may be issued upon conversion of the Preferred Shares, the "Conversion Shares"), for an aggregate purchase price of $485.0 million, or $1.00 per Preferred Share, and (ii) an aggregate of 251,163 Common Shares, for an aggregate purchase price of $15.0 million, or $59.722 per Common Share. The PIPE Transaction closed on February 1, 2023 (the "Issue Date").

Pursuant to the terms of the Purchase Agreement, upon the approval by the Issuer's shareholders of the issuance of Common Shares in connection with the transactions contemplated by the Agreement and Plan of Merger and Reorganization, dated as of November 7, 2022, by and among the Issuer, Ritchie Bros. Holdings, Inc., a Washington corporation, Impala Merger Sub I, LLC, a Delaware limited liability company, Impala Merger Sub II, LLC, a Delaware limited liability company, and IAA, Inc., a Delaware corporation (the "Merger") and IAA, Inc.'s ("IAA") shareholders of the Merger by both the Issuer and IAA shareholders (the "Appointment Event"), the Issuer will increase the size of its Board of Directors (the "Board") from nine to ten directors and appoint Mr. Smith, as a member of the Board. As a condition to Mr. Smith's appointment to the Board, Mr. Smith is required to submit an irrevocable resignation letter pursuant to which he will resign from the Board automatically and immediately if (A) Starboard fails to beneficially own in the aggregate at least 50.0% of the Common Shares and Preferred Shares (on an as-converted basis and subject to adjustment for share splits, reclassifications, combinations and similar adjustments) purchased in the PIPE Transaction or (B) Starboard or Mr. Smith materially breaches certain provisions of the Purchase Agreement (each, a "Resignation Event"). If the Appointment Event has occurred, and so long as there has been no Resignation Event, the Board will nominate Mr. Smith, along with its other nominees, for election to the Board at the Issuer's 2023 annual meeting of shareholders (the "2023 Annual Meeting") for a term expiring at the Issuer's 2024 annual meeting of shareholders and the Issuer will recommend, support and solicit proxies for the election of Mr. Smith at the 2023 Annual Meeting in the same manner as it recommends, supports, and solicits proxies for the election of any continuing director.

Pursuant to the terms of the articles of amendment of the Issuer, amending the Issuer's Articles of Amalgamation (the "Articles of Amendment"), holders of the Preferred Shares will have the right to convert their Preferred Shares any time or times on or after the Issue Date into a number of Common Shares equal to the face amount of such Preferred Shares multiplied by the then-applicable conversion rate (the "Conversion Rate"). The Conversion Rate will initially be 0.0136986 Common Shares per $1.00 face amount of Preferred Shares, subject to customary anti-dilution adjustment provisions.

In connection with the PIPE Transaction, on the Issue Date, the Issuer and the Starboard Vehicles entered into a registration rights agreement (the "Registration Rights Agreement") pursuant to which the Issuer has agreed to grant the Starboard Vehicles certain customary registration rights (under U.S. securities laws) with respect to the Common Shares, the Conversion Shares and certain other securities that may be issued to the Starboard Vehicles in respect thereof, subject to specified limitations.

	The foregoing descriptions of the Purchase Agreement, the Articles of Amendment and Registration Rights Agreement are qualified in their entirety by reference to the full text of the Purchase Agreement, which is included as Exhibit 10.1 to the Issuer's Current Report on Form 8-K, filed with the Securities and Exchange Commission (the "SEC") on January 23, 2023, the Articles of Amendment, which is included as Exhibit 3.1 to the Issuer's Current Report on Form 8-K, filed with the SEC on February 1, 2023, and the Registration Rights Agreement, which is included as Exhibit 10.1 to the Issuer's Current Report on Form 8-K, filed with the SEC on February 1, 2023, and included as Exhibit 99.1, Exhibit 99.2 and Exhibit 99.3, respectively, hereto.

	No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer's financial position and investment strategy, the price levels of the Common Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in additional communications with management and the Board, engaging in discussions with stockholders of the Issuer or other third parties about the Issuer and the Reporting Persons' investment, including potential business combinations or dispositions involving the Issuer or certain of its businesses, making recommendations or proposals to the Issuer concerning changes to the capitalization, ownership structure, board structure (including board composition), potential business combinations or dispositions involving the Issuer or certain of its businesses, or suggestions for improving the Issuer's financial and/or operational performance, purchasing additional Common Shares, selling some or all of their Common Shares, engaging in short selling of or any hedging or similar transaction with respect to the Common Shares, including swaps and other derivative instruments, or changing their intention with respect to any and all matters referred to in Item 4.

Item 5.	INTEREST IN SECURITIES OF THE ISSUER.

(a)	The percentages used in this Schedule 13D are calculated based upon 111,138,974 outstanding Common Shares, which is the sum of (i) 110,887,811 Common Shares reported to be outstanding as of January 25, 2023, as reported in the Issuer's Prospectus filed with the SEC pursuant to Rule 424(b)(3) on February 10, 2023 and (ii) 251,163 Common Shares issued pursuant to the Purchase Agreement, and assumes the conversion of the reported Preferred Shares.

See rows (11) and (13) of the cover pages to this Schedule 13D for the aggregate number of Common Shares and percentage of the Common Shares beneficially owned by each of the Reporting Persons. The filing of this Schedule 13D shall not be deemed an admission that the Reporting Persons are, for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, the beneficial owners of any securities of the Issuer that he or it does not directly own. Each of the Reporting Persons specifically disclaims beneficial ownership of the securities reported herein that he or it does not directly own.
