**RBA Yard Video Transcript**

This is an exciting time for Ritchie Bros. Given the upcoming Special Meeting, I felt it was important for me to share one of the many reasons why we are so passionate about the IAA transaction.

Since I was appointed CEO in 2020, we have been on a journey to transform the Company from a traditional auction business with low growth to a trusted global marketplace for value-added insights, services and transaction solutions.

Our success is evident in our outstanding performance and superior shareholder returns.

A core component of our growth strategy is expansion through satellite yards.

Satellite yards make it easier for new and existing customers to do business with Ritchie Bros. In fact, 50% of our sellers using these yards are new to the Ritchie Bros. ecosystem. This customer exposure fuels our marketplace flywheel.

We're absolutely convinced this is the right strategy. However, it is not without its challenges.

While satellite yards are critical for growth and we're excited about their potential, they are very different from the traditional Ritchie Bros. yards, and so far we have only been able to stand up roughly 24. Why is this the case?

Ritchie Bros.' traditional yards are very large plots of land far from population centers. We've owned them for a long time, the land is cheap, and they benefit from significant economies of scale.

Satellite yards, on the other hand, are only about 10% of the size of a traditional Ritchie Bros. lot and need to be located much closer to population centers to reduce transportation costs for sellers.

From scouting to negotiating to activation, cold start satellite yards are time consuming to stand up. As is the case with any transformation, finding the right formula has been challenging.

One of the reasons I am so excited about the IAA acquisition is that it will allow us to greatly accelerate our work and help us pursue a huge market opportunity.

First, IAA's yards are ideally located close to population centers where Ritchie Bros. needs them most. In fact, we project that we will be able to utilize a significant number of IAA's current 210 locations as satellite yards.

Second, IAA has excess capacity Ritchie Bros. can use. Overall utilization across IAA's yards is approximately 55%. Roughly 75% of IAA yards have more than five acres of availability. Ritchie Bros. can use this capacity to serve seller demand and still maintain high levels of service in the core IAA business.

Third, IAA's yards have the potential to unlock significantly higher returns for Ritchie Bros. Leveraging IAA yards virtually eliminates the start up time associated with standing up new yards, and minimizes incremental costs because they are already staffed. Because the incremental costs are so low, and each of the existing IAA yards are already profitable, the financial hurdles associated with our existing satellite yard strategy are almost nonexistent. Every unit that comes to these locations results in incremental margin and should be significantly accretive.

In short, our yard strategy is critical to our future growth. And IAA is critical to our yard strategy. Through this acquisition, we significantly accelerate our biggest strategic initiative AND acquire a very good business that will provide increasing value as we grow over time with enhanced performance driven by our leadership.

I greatly appreciate the support you have extended to me since I was appointed CEO and look forward to building on our significant momentum through the IAA acquisition.

Need for Capacity at Lower Costs and With Much Higher Returns Amended Agreement with IAA Delivers Even Greater Value for Ritchie Bros.' Shareholders Ritchie Bros. Shareholders Are Urged to Vote "FOR" All Proposals on the WHITE Proxy Card Visit www.RBASpecialMeeting.com for More Information VANCOUVER, BC (February 13, 2023) – Ritchie Bros. Auctioneers Incorporated (NYSE: RBA) (TSX: RBA) ("Ritchie Bros.") today announced that it has commenced mailing its proxy materials in connection with the Company's Special Meeting of Shareholders to vote on the proposals that are necessary to complete its previously announced acquisition of IAA, Inc.

Ann Fandozzi, CEO of Ritchie Bros., said, "Since our transaction was announced, we have heard from numerous new and existing Ritchie Bros. shareholders who are supportive of the substantial value created through the IAA acquisition.

Shareholder, This is an exciting time. On March 14, 2023, Ritchie Bros. is scheduled to hold a Special Meeting of Shareholders to vote on proposals necessary to complete our previously announced acquisition of IAA. This transaction advances the Company's strategic transformation underway and provides compelling growth opportunities that will enable us to continue our track record of superior shareholder returns. In fact, the value we see with this transaction substantially exceeds our standalone plan – potentially driving incremental value from cost synergies and revenue opportunities of up to $76 per Ritchie Bros. sharei .. Your vote is important to ensuring this value can be realized. The Ritchie Bros. Board of Directors unanimously recommends that Ritchie Bros. shareholders vote "FOR" on the WHITE proxy card for each of the proposals that are being considered at the Special Meeting. OUR TEAM'S EXECUTION HAS TRANSFORMED RITCHIE BROS. AND IS CREATING SIGNIFICANT, SUSTAINABLE SHAREHOLDER VALUE When I was appointed CEO in 2020, Ritchie Bros. had solid core assets and talented employees, but its business was stagnant. Since then, we have recruited new leaders, and through organic initiatives, partnerships and strategic acquisitions, we have taken bold steps to redefine our operating model and reinvigorate profitable growth. As a result, we have transformed Ritchie Bros. from a traditional auction business to a trusted global marketplace for value-added insights, services and transaction solutions. We now operate across seven verticals, have launched new go-to-market models and have a steadily growing number of yards. All of these differentiators work in tandem to strategically increase customer demand, creating a flywheel of growth and profitability. Our success is evident in our outstanding performance, even in the face of the global COVID-19 pandemic. In just three yearsii, we have achieved: • $800 million in Gross Transaction Value (GTV) growthiii • Record 10-year highs in revenue growth, a double-digit increase • Double-digit adjusted EBITDA growth from $315 million to $442 millioniv • ~300 bps adjusted EBITDA margin expansion  |

We have deep industry experience that we can leverage to successfully integrate IAA and accelerate growth. Previously, our leadership team has held executive and operating leadership positions at Abra, Cox Automotive, Caliber Collision, DaimlerChrysler, DealerTrack, Ford, Pep Boys, vRide and Wheels Up. The Ritchie Bros. Board of Directors also has expertise in the broader automotive industry and M&A, as well as in technology and sales and other relevant areas. We know how to acquire and integrate to create value. The Ritchie Bros. Board and management team, with input from our advisors, identified IAA as a potential combination for Ritchie Bros. back in mid-2020, and evaluated a possible acquisition of IAA for more than 12 months. The strategic logic of this combination is clear. With IAA, we expand our reach into an attractive, adjacent vertical with a growing business and, by adding our services and operating expertise, we can unlock IAA's full potential. • The salvage vehicle market has strong secular tailwinds. The number of registered vehicles on the road and the average vehicle age have increased 14%v and 7%vi, respectively, since 2013. These factors combined with rising accident rates have resulted in secular growth in automotive salvage volumes. These growth trends are expected to continue. • IAA is a leading player in this attractive market and has shown counter-cyclicality and resilience through economic cycles. IAA has grown revenue each year since 2000vii including during the 2007 to 2009 downturn. |

IAA's 210 facilities are located in close proximity to Ritchie Bros. customers throughout the United States, Canada and the United Kingdom and include a developed network automated by technology. • IAA's positive performance is continuing. For fiscal 2022, IAA previously stated that it expects revenue, net income and adjusted EBITDA that are in-line with or above FactSet mean consensus analyst estimates as of February 10, 2023. IAA WILL CATAPULT RITCHIE BROS.' STANDALONE YARD STRATEGY TO A WHOLE NEW LEVEL, RESULTING IN HIGHER ROI, HIGHER GROWTH AND HIGHER SHAREHOLDER RETURNS We believe commercial asset markets are on the cusp of substantial growth. Equipment supply could increase meaningfully in the coming quarters as the economic cycle turns. To capitalize on this shift, having access to a robust network of satellite yards is critical. Ritchie Bros. has been investing in small satellite yards close to population centers, but organic satellite yard expansion is time consuming given the scouting, negotiation and activation processes required. IAA's existing yards present the opportunity to immediately address our need for capacity and at a lower cost with much higher returns. • IAA yards are ideally located: IAA's yards are located close to population centers where Ritchie Bros. needs them most. Ritchie Bros. will be able to utilize a significant number of IAA's current locations as satellite yards. • IAA has excess capacity that Ritchie Bros. can use: IAA has 210 yards with approximately 10,000 acres of capacityviii. These yards are underutilized. Overall utilization across IAA's yards is 55%. Roughly 75% of IAA yards have more than five acres of availability. Ritchie Bros. can use this capacity to serve the expected rising heavy equipment demand without hurting service levels in the core IAA business. • IAA's yards are expected to unlock significantly higher returns for Ritchie Bros.: Leveraging IAA yards virtually eliminates the start-up time associated with standing up new yards, and minimizes incremental cost because they are already staffed. Indeed, because the incremental costs are so low, and each of the existing IAA yards are already profitable, we can easily overcome the financial hurdles associated with expanding our existing satellite yard strategy. Every Ritchie Bros. unit that comes to these IAA locations would result in incremental margin and therefore should be highly accretive. In addition, using IAA's yards' open capacity should yield significantly higher ROI. By definition, standing up dedicated yards on our own requires incremental costs, but more than that, cold start locations require time to gather critical seller mass, which leads to suboptimal financial performance. Our volume changes the economics of the IAA yards – for the better. In short, our yard strategy is critical to our future growth. And acquiring IAA is critical to our yard strategy. With IAA, we will accelerate our yard footprint expansion at lower cost with strong returns – both turbocharging our biggest strategic initiative and acquiring a very good business at a good value. |

In particular, we expect: • Sizeable EBITDA opportunityix: ~$350 million to $900 million opportunity, or up to ~$61 per share including cost savings and total revenue opportunitiesx - Highly realizable cost savings: At least $100 million to $120 million, or ~$8 per share, of cost savings by the end of 2025xi - Revenue growth opportunities: ~$250 million to $780 million of incremental EBITDA from potential revenue opportunities • Potential valuation upsideix: Up to $15 of additional value upside per share from cost synergies and revenue opportunities, reflecting an illustrative re-rating from 13x to 16x EV / NTM EBITDA multiple. Ritchie Bros. traded at a 16x multiple prior to announcing the transaction, and 16x is the historic blended multiple for Ritchie Bros./IAA • Clear path to deleverage and advance our capital allocation strategy: Strong free cash flow, providing financial flexibility to continue investing in the business and enabling rapid deleveraging to a targeted leverage ratioxii of 2.0x within 24 months. We believe this could support further multiple expansion and as target leverage ratios are met, we are committed to returning capital to shareholders Actionable and thorough integration planning has already begun. We have established an integration management office (IMO) comprised of dedicated, experienced operators and leaders to ensure this integration plan is executed seamlessly. The IMO will be supported by a leading third-party consultant and overseen by a steering committee that will have clear charters, milestones and KPIs to drive accountability. Work will be focused on critical success factors, including ensuring continued strong business performance and delivering on cost synergies and revenue opportunities. OUR AMENDED AGREEMENT WITH IAA AS WELL AS THE TRANSACTION WITH STARBOARD REFLECT SHAREHOLDER FEEDBACK AND DELIVER EVEN GREATER VALUE We have engaged extensively with our shareholders about the IAA transaction, and increasingly they understand its merits and have become excited about the potential of the combination. This is evidenced by Ritchie Bros.' meaningful stock price improvement from observed lows since the transaction was announced in November. Through our dialogue with shareholders, it also became clear that both Ritchie Bros. and IAA shareholders preferred – for differing reasons – a change to the consideration mix and transaction structure. On January 23, 2023, Ritchie Bros. and IAA announced an amended agreement that reflects this feedback and provides greater accretion and even more compelling value to Ritchie Bros. shareholders, and greater cash to IAA shareholders. The amended agreement and the additionally announced $500 million investment from Starboard (which closed on February 1) would result in the following: • Ritchie Bros. shareholders receive approximately $115 millionxiii of additional value through: - A $0.52xiii reduction in the price paid per IAA share, or approximately $70 million in the aggregate |

Good morning team,

I am writing to share an update on our pending acquisition of IAA. Today, we took an important step toward closing this transaction and officially bringing our companies together.

As you will recall, the closing of our transaction is subject to the approval of Ritchie Bros. shareholders, and on March 14, 2023, we will hold a Special Meeting of Shareholders to vote on proposals related to the transaction. On Friday, we filed our final proxy statement with the U.S. Securities and Exchange Commission and began mailing it to our shareholders. A proxy statement outlines information that shareholders need to know about the acquisition, including why we believe this is such an outstanding combination. It also includes instructions on how shareholders can vote, such as by mail, by phone or online. We have established a dedicated website with similar information that you can see here www.RBASpecialMeeting.com.

If you own Ritchie Bros.' shares, you will be receiving these proxy materials, and we encourage you, like all shareholders, to vote "FOR" on the WHITE proxy card for each of the proposals that are being considered at the Special Meeting.

For everyone, I want to say thanks and job well done. I have talked recently with numerous Ritchie Bros. shareholders, including several of our largest shareholders who are overwhelmingly supportive of the transaction. In my shareholder conversations, it is clear they appreciate our team and our many achievements, which are the direct result of your contributions. The strong preliminary financial results we announced this morning are just one of the proof points that show our momentum.

I look forward to continuing to build on the magnificent business we have created.

All my best,

Ann
