  • Eli Lilly's retatrutide achieved 28.3% average weight loss in a 2,339-patient Phase 3 trial, with 65.3% of patients falling below the obesity BMI cutoff and 45.3% losing at least 30% weight.
  • Retatrutide is the first triple agonist (GLP-1, GIP, glucagon) and showed no cardiac or liver side effects in this trial.
  • NextEra Energy agreed to buy Dominion Energy for $67B in an all-stock deal, creating a combined company worth ~$249B market cap and ~$420B enterprise value.
  • The merger positions the combined entity as the third-largest U.S. energy company, critical for serving data center power demand expected to consume 17% of U.S. electricity by 2030.
  • SpaceX publicly filed for a $1.75T valuation IPO targeting $75B raise, with 2025 revenue of $18.7B and $4.94B loss; Starlink is the only profitable segment with $4.4B operating income.
