AI commentary
High-coverage post-earnings follow-up with concrete company-source results and visible market reaction. The stock traded near $946.48 on May 29 versus the $995.20 May 28 anchor, so the immediate tape is negative despite strong company-reported sales, comp, membership, and digital metrics. Analyst revision evidence remains unavailable in the checked packet and sources; missing revisions are not treated as positive evidence.

The stock moved lower after the earnings release, trading near $946.48 on May 29 versus the $995.20 May 28 anchor price, despite the company-reported sales, comp, EPS, and renewal metrics. That price action points to valuation and margin digestion rather than an immediate positive re-rating.
