Executive summary

  • Q3 2025 adjusted EPS was $1.60, exceeding estimates by $0.10, with net income rising 11.5% year-over-year to $1.7 billion, driven by robust customer growth, higher retail electric revenues, and strong demand from data centers and industrials.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
