Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the identifiable net assets acquired. We had no changes to the carrying amount of goodwill during the nine months ended September 30, 2026. We had no accumulated impairment losses related to our goodwill as of September 30, 2026.

During the third quarter of 2026, we completed our annual goodwill impairment test for goodwill we carried as of July 1, 2026. No impairment resulted from this test.

Other Indefinite-Lived Intangible Assets

At September 30, 2026 and December 31, 2025, we had $49.9 million and $5.3 million, respectively, of other indefinite-lived intangible assets included in other long-term assets on our balance sheets. In July 2026, we along with WE, entered into an option agreement, and we made a refundable payment of $44.6 million for exclusive rights to purchase our share of certain generation projects to be constructed in Wisconsin.
