  • Initial conversion price of about $210.58 per share, a 47.5% premium over the $142.77 closing price on August 27, 2026
  • Capped call transactions cost approximately $285.0 million; estimated net proceeds are about $2,957.3 million including the option

Written later: this filing was briefed after the fact, when past filings were added to the site, so the brief may be read with hindsight; the filing itself is the record of what was known on September 01, 2026.

Briefs are written by AI from the filing text (each brief's own page names the model) and can contain mistakes — open the filing before acting on anything. Impact (1-5) and tone are the model's reading of the filing for shareholders, not a price forecast. Not investment advice.
