What is the total value of the Calpine acquisition for CEG shareholders?

Based on CEG's December 3, 2025 closing price of $361.26, the total estimated merger consideration is about $22.4 billion, comprising roughly $17.9 billion in stock (after excluding shares subject to post-combination vesting) and $4.5 billion in cash. The value moves with CEG's share price: a 10% increase would raise consideration to about $24.2 billion, and a 10% decrease would lower it to about $20.7 billion.

Will the deal be accretive to earnings?

The filing does not make an accretion claim. The unaudited pro forma figures show higher per-share earnings for 2024 ($13.87 diluted pro forma versus $11.89 historical) and nine-month 2025 ($7.57 versus $6.02). However, these figures exclude expected synergies and reflect preliminary fair value estimates, so they are illustrative rather than a forecast.

Why are four Calpine plants being sold, and does that affect the deal?

The four plants (Bethlehem, York Unit 1, Hay Road and Edge Moor) were identified in the merger agreement for divestiture to address market power concerns raised in the FERC approval process. Their carrying value is about $4.36 billion in held-for-sale assets. The filing says proceeds are unknown, so any gain or loss on sale is not reflected in the pro forma statements and will depend on the final sale price.

What are the main risks to closing the transaction?

The filing cites several risks: failure to obtain required governmental and regulatory approvals or conditions that cause abandonment, inability to satisfy closing conditions on time, integration difficulties, failure to achieve expected synergies, and events that could lead to termination of the merger agreement. The filing also notes that Calpine's interim operating covenants could constrain its business while the deal is pending.

How will the acquisition change CEG's balance sheet?

On a pro forma basis at September 30, 2025, total assets rise to about $96.0 billion from $56.2 billion, and long-term debt rises to about $19.1 billion from $7.3 billion. Goodwill increases to about $11.6 billion from $0.4 billion. Shareholders' equity increases to about $32.2 billion, driven by the stock consideration. The filing does not present a leverage target or rating outcome.

CEG 8-K SEC Disclosure

01—Abstract

Summary

Summary of the 8-K filed December 9, 2025. Cited figures are marked; the original filing is the authoritative source.

This 8-K, filed December 9, 2025 by Constellation Energy Corporation (CEG) and Constellation Energy Generation, LLC, furnishes the historical and pro forma financial statements tied to CEG's pending acquisition of Calpine Corporation, under the Agreement and Plan of Merger signed January 10, 2025.

It contains no new operating guidance or earnings results. Its main value to investors is the preliminary deal economics: CEG will issue 50 million shares plus $4.5 billion^a in cash. Based on CEG's $361.26 share price on December 3, 2025, the estimated merger consideration is about $22.4 billion.

The pro forma analysis implies roughly $11.2 billion^b of preliminary goodwill, about $9.8 billion of property, plant and equipment fair value step-up, and about $4.4 billion of assets classified as held for sale. The pro forma combined company would have about $96.0 billion in total assets and $19.1 billion of long-term debt as of September 30, 2025. Pro forma 2024 net income attributable to common shareholders is $5.07 billion, or $13.87 diluted EPS, versus CEG's historical 2024 diluted EPS of $11.89.

Pro forma nine-month 2025 diluted EPS is $7.57^c, versus $6.02 historically. These figures are illustrative only. They exclude expected cost synergies and reflect planned divestitures, and the purchase price allocation is preliminary and could change materially.

Calpine's own results softened in 2025, with nine-month net income falling to $948 million^d from $1,449 million, largely due to mark-to-market losses on derivatives. An important development is that four Calpine assets (Bethlehem Energy Center, York Energy Center Unit 1, Hay Road Energy Center and Edge Moor Energy Center) were reclassified to held for sale after conditional FERC approval. The merger agreement identifies these assets for divestiture to address market power concerns.

Completion of the deal also depends on other regulatory approvals and the closing conditions, and the filing notes that a debt exchange of up to $2.4 billion of CEG fixed-rate debt for Calpine debt is contingent on the merger closing. Investors should treat the filing as a detailed snapshot of the transaction structure rather than a signal of imminent closing.

02—Key points

Key Highlights

Deal consideration: 50 million newly issued CEG Parent shares plus $4.5 billion in cash for Calpine, implying roughly $22.4 billion total merger consideration at CEG's December 3, 2025 closing price of $361.26.
Preliminary purchase accounting: about $11.2 billion of goodwill, a $9.8 billion net PP&E fair value step-up, and $1.8 billion of unamortized energy contracts, all subject to final valuation within 12 months of closing.
Planned divestitures: four Calpine plants (Bethlehem, York Unit 1, Hay Road, Edge Moor) are classified as held for sale, carried at about $4.36 billion in total, to address FERC market power concerns.
Pro forma earnings: 2024 pro forma diluted EPS of $13.87 versus CEG's historical $11.89, and nine-month 2025 pro forma diluted EPS of $7.57 versus $6.02 historically, before synergies.
Pro forma leverage: combined long-term debt of about $19.1 billion and total equity of about $32.5 billion as of September 30, 2025, with $4.5 billion of cash consideration reducing CEG's cash balance to about $608 million pro forma.
Calpine standalone softness: nine-month 2025 net income fell to $948 million from $1,449 million, with operating income down to $1.8 billion from $2.4 billion, driven by mark-to-market losses and higher other operating expenses.
Financing: a private exchange offer of up to $2.4 billion of CEG fixed-rate debt for Calpine debt was launched December 9, 2025, contingent on merger closing and not included in the pro forma figures; the merger is not subject to a financing condition.
