- Financing summary: For the broader Energy Harbor corporate acquisition announced by Vistra on 2023-03-06, consideration consisted of $3.0 billion in cash, a 15% ownership interest in Vistra Vision, and assumption of approximately $430 million of Energy Harbor net debt. Vistra stated that most of the cash consideration would be financed through debt at Vistra Operations, with some or all of that debt potentially provided to Vistra Vision through an intercompany loan; the acquisition closed on 2024-03-01. The approximately $3.43 billion figure represents the expected cash-plus-assumed-net-debt transaction financing structure, not a Perry-only purchase price. — Vistra Announces Acquisition of Energy Harbor · confidence: medium

## Data quality

- The March 2023 acquisition consideration was for Energy Harbor's broader nuclear and retail businesses, not a separately disclosed Perry-only sale price. The 2000 power uprate increased authorized reactor thermal power from 3,579 MWt to 3,758 MWt; this is a reactor thermal-power milestone and should not be treated as a separate additional unit. The 2023 decommissioning report stated that formal decommissioning had not started and used a modeled 2026 shutdown assumption. That assumption was superseded as an operating-status indicator by the 2025 license renewal extending authorization through 2046.
