On a GAAP basis, net income available to common shareholders for the quarter ended September 30, 2026 was $129.5 milliona, or $0.27 per diluted share, compared with $94.7 million, or $0.20 per diluted share, in the same period of 2025. Non-GAAP adjusted net income available to common shareholders was $130.9 million, or $0.27 of consolidated adjusted EPS, versus $91.8 million, or $0.19, a year earlier. For the nine months ended September 30, 2026, GAAP net income available to common shareholders was $685.7 million ($1.42 per diluted share), and adjusted net income was $718.1 million ($1.49 of consolidated adjusted EPS).

The company narrowed its 2026 non-GAAP consolidated adjusted EPS guidance to the upper half of the $2.02b-$2.07 range and introduced 2027 guidance of $2.22-$2.30. It extended its capital plan through 2033, with a seven-year consolidated total capital expenditure plan of $40.0 billion, comprising $32.0 billion of base plan capital expenditures and $8.0 billion for data center investments. The company expects 9%-10% consolidated investment base growth from 2027-2033, a consolidated non-GAAP adjusted EPS compound annual growth rate of 10%-11% for 2027-2033 (raised from prior expectations as stated in the release), and base plan adjusted EPS annual growth of 6%-8%, with 8%-10% rate base growth from 2027-2033.

Management also announced an expanded agreement with Microsoft, bringing expected GenCo cost savings for existing customers to approximately $1.75 billionc. The company now presents base plan adjusted EPS, which excludes the impact of data center operations and development, alongside consolidated adjusted EPS. Adjustments in the third quarter included a $6.0 million Value Captured initiative cost and a $4.0 million favorable weather impact, and for the nine months included a $21.4 million workplace continuity cost tied to the April 2026 lockout period.
