Disclosed a multi-year agreement expecting to supply more than $4 billion of data-center cooling to one unnamed customer across 2027-2029, with explicit no-assurance language. That forward visibility sits alongside rising concentration: top-ten customers reached 49% of fiscal 2026 net sales from 43% a year earlier. No single customer topped 10% last year; whether this agreement crosses that disclosure threshold as volumes ramp remains an open monitoring item. Funnel is swelling, but I wouldn't extrapolate.
