Transmission Segment Performance

WEC ENERGY GROUP, INC. · 2026-10-30 · Importance 41 · Surprise 48

The electric transmission segment’s net income attributed to common shareholders increased $22.6 million, or approximately 20.6%, to $132.4 million for the nine months ended September 30, 2026. Equity in earnings of transmission affiliates rose $27.6 million to $187.9 million, primarily because of continued capital investment by ATC. The increase was partly offset by a $3.6 million gain recognized at ATC Holdco in March 2025 that did not recur, and income tax expense increased $7.7 million as pre-tax income rose.
