PRISM REASONING
  • Fundamental analysis slightly favors a post‑recovery Memorial Day passenger count above 2,980,000
  • The lack of a named official source and strictness of “above” add uncertainty and keep confidence low
FACTORS FOR
  • +Memorial Day weekend historically near 2.6–2.9 million screenings
  • +Post‑pandemic recovery and projections trending modestly higher into 2026
FACTORS AGAINST
  • Threshold set near historical upper range leaves limited upside room
  • No verified official 2026 guidance or early‑season traffic confirmation
RESOLUTION PATHS MODELED
Robust 2026 travel pushes Memorial Day above 2,980,000 screenings36%
Slight increase over recent Memorial Days barely clears 2,980,00020%
