Summary

Summary of the 8-K filed May 19, 2025. Cited figures are marked; the original filing is the authoritative source.

Talen Energy Corporation (TLN) furnished a Regulation FD update on May 19, 2025 regarding the ongoing planned refueling outage on Unit 2 at its Susquehanna Steam Electric Station.

The outage began in late March. Following the May 8, 2025 earnings release and investor call, the Company said incremental balance-of-plant maintenance in the extraction steam system would extend the outage into mid-May and add approximately $20 milliona in costs. The underlying maintenance work is now complete, but realignment and assembly required rework to pass quality testing.

The Company is in the final stages, focused on testing, final welds and alignment verifications. The outage timeline has been revised from mid-May to the first week of June. The Company now expects the extension to increase expenses by approximately $35 millionb.

Management anticipates efficiency gains will pay back the additional costs and lost margin in roughly two years. The Company states that its financial guidance for 2025 remains unchanged.

CEO Mac McFarland said the slightly longer timeline reflects the importance of improving the performance of this long-lived asset. The information is furnished under Item 7.01 and is not deemed filed for purposes of Section 18 of the Exchange Act.
