“FOR” All Proposals on the WHITE Proxy Card

VANCOUVER, BC, March 7, 2023 – Ritchie Bros. Auctioneers Incorporated (NYSE: RBA) (TSX: RBA) (“Ritchie Bros.”) today reiterated the Board of Directors’ unanimous recommendation that Ritchie Bros.’ shareholders vote “FOR” all proposals listed on the WHITE proxy card in connection with the upcoming Special Meeting of Shareholders related to the acquisition of IAA, Inc. (NYSE: IAA) (“IAA”). In addition, Ritchie Bros. stated that independent proxy advisory firm Egan-Jones Proxy Services (“Egan-Jones”) has recommended that Ritchie Bros. shareholders vote “FOR” the transaction.

The Special Meeting, which is scheduled for March 14, 2023, is fast approaching. Shareholders are urged to vote TODAY to ensure their vote is promptly recorded. Materials related to the Special Meeting and instructions on how to vote “FOR” the IAA acquisition can be found at www.RBASpecialMeeting.com.

Ann Fandozzi, CEO of Ritchie Bros., said, “A vote ‘FOR’ the IAA acquisition is a vote ‘FOR’ the Board, management team and strategy that have delivered outstanding returns for Ritchie Bros.’ shareholders, including a 48% return over the past several years^[i]. The IAA acquisition is a unique opportunity to drive even greater growth and value creation far exceeding what Ritchie Bros. could achieve standalone. Our Board and management team are confident that this is the right transaction at the right time and that we have the industry experience and operating expertise to capture the significant upside potential we can create together with IAA.”

In reiterating the Board’s recommendation that Ritchie Bros. shareholders vote “FOR” the IAA acquisition, Ritchie Bros. noted:

The strategic and financial benefits of the IAA transaction are compelling for Ritchie Bros. shareholders. IAA expands our reach into an attractive, adjacent vertical with a growing, countercyclical business. We believe the Ritchie Bros. + IAA combination will act as an accelerant to our transformation and enable us to build on our record of growth and superior value creation well into the future. Indeed, the $350 million to $900 million^[ii] of total estimated potential EBITDA from expected cost savings and revenue opportunities represents up to an additional $76 per share in potential value^[iii] — more than double Ritchie Bros.’ closing stock price of $60.89 as of yesterday, March 6, 2023. This potential value is comprised of up to $61 per share of potential value from cost savings and incremental revenue opportunities at the pre-transaction blended multiple and up to $15 per share of potential value from multiple expansion to the average IAA-Ritchie Bros. blended multiple since the IAA spin.

Further, the transaction will more than double Ritchie Bros.’ gross transaction value (GTV)^[iv] as of year-end 2022, as we offer more customers more value-added services and solutions, supporting deeper relationships and accelerating our marketplace flywheel.

The estimated cumulative free cash flow^[v] of $2.5 billion from 2023 to 2026 will provide financial flexibility to continue investing in the business and enabling rapid deleveraging to 2.0x^[vi] adjusted EBITDA within 24 months post close.

Ritchie Bros.’ management team is proven and has the right experience to successfully execute on this transaction. Detailed integration plans have been developed; dedicated, experienced integration operators and leaders have been appointed; and a steering committee with clear charters, milestones and KPIs has been established to drive integration accountability. We are excited to bring Ritchie Bros. and IAA together and look forward to the significant value creation opportunities ahead.

In making its recommendation that Ritchie Bros. shareholders vote “FOR” all proposals being considered at the Special Meeting, Egan-Jones stated in its March 6, 2023 report^[vii]:

“We believe that there is a compelling reason to vote on the proposed merger of RBA and IAA as the benefits of combining the two companies outweigh the benefits of remaining as a stand-alone company. In our view, the merger sets a realistic approach of shareholder value creation and maximization in the long-run.”

“We believe that the merger will be financially accretive to RBA representing a $250-$780M of EBITDA potential to accelerate de-leveraging, thus enhancing capital allocation, capital return and cost reduction. We believe that the financial attractiveness of the transaction will further drive growth opportunities for RBA.”

“We believe that IAA’s business will complement RBA’s strategic vision to position itself as a key player in the industry. By the consummation of transaction, it is expected that combined yard footprint will enhance customer experience and strong market position, thereby opening cost synergies and revenue opportunities.”
