RB Global: The Sell-Off Looks Overdone; We Stay Buy

The key issue is not top-line growth but the conversion of that growth into cash earnings. When revenue outpaces EBITDA by this much, the market starts questioning whether the platform is getting more transactional but less monetizable, which usually compresses the multiple before it shows up in consensus estimates. The risk is that lower take rates are not a one-quarter noise item but a sign that RB Global is paying up for growth via mix shift, acquisitions, or competitive pricing in higher-frequency categories.

Competitive dynamics look more nuanced than the headline suggests. The insurer relationship and auto share gains reinforce that RB Global has real distribution power, but that also implies the company is increasingly competing on service breadth rather than pure auction economics, which can cap near-term margin expansion. BigIron is strategically interesting, but agriculture is a slower-turning, more fragmented market with potentially lower monetization initially; the first-order effect may be TAM expansion, while the second-order effect is dilution of consolidated margins until cross-sell and integration synergies are proven.

Over the next 1-3 months, the stock is likely to trade on whether management can stabilize take rate and show that acquisition mix normalizes. Over 6-18 months, the bull case is that RB Global becomes a broader asset-disposition platform with durable network effects; the bear case is that it becomes a larger but lower-margin roll-up. What would falsify the bearish view is evidence of EBITDA margin reacceleration despite continued GMV share gains; what would falsify the bull case is another quarter where revenue growth materially exceeds EBITDA growth and guidance does not call for margin recovery.
