Executive Summary
A federal magistrate judge granted a routine motion to compel a non-party (HTI Polymer Inc.) to comply with a subpoena in a personal injury premises-liability case against Costco. The ruling is a procedural discovery order that compels a third-party contractor to produce documents; it has no financial impact on Costco and does not address liability or damages. This is a Tier 4 procedural ruling with no material effect on Costco's business or stock price. The historical calibration shows past neutral reports on COST have had mixed outcomes (38% win rate at T+20), but this event is too trivial to warrant a directional call. The cross-filing actuarial verdicts (amplifiers for court-amendment + prior-ruling + settlement contexts) do not apply here as this is a routine discovery motion, not a substantive ruling.
