Merck Q2 2026 earnings; Keytruda revenue (LOE timeline); Gardasil expansion; Winrevair PAH launch; pipeline oncology updates

Thesis breaks if Keytruda LOE ~2028 comes faster than modeled (US biosimilar erosion on a 48.7%-concentrated revenue base, Q2 already -1% YoY), Gardasil China keeps declining (H1 -9% YoY), or balance-sheet stress ($16B M&A in 6 months, net debt/equity 1.11x, 35-36% tax rate) constrains pipeline funding. (vault 2026-08)

Bullish — Positive Phase 3 mRNA melanoma vaccine results with Moderna (Aug 19, 2026); Keytruda combo keeps cancer from returning. [X search Aug 2026]
