For the quarter ended March 31, 2026, Talen reported GAAP Net Income of $63 million, Adjusted EBITDA of $473 million, and Adjusted Free Cash Flow of $350 million. Compared with the three months ended March 31, 2025:

GAAP Net Income increased by $198 million primarily due to increases of capacity revenues and energy and other revenues, net of fuel and energy purchases that were partially offset by increases in interest expense and other finance charges as well as income tax expense.
Adjusted EBITDA increased by $273 million primarily due to increases in capacity revenues and energy and other revenues, net of fuel and energy purchases.
Adjusted Free Cash Flow increased by $263 million primarily due to increases in capacity revenues and energy and other revenues, net of fuel and energy purchases, which were partially offset by higher cash interest payments.

(a) Excludes impact of the Cornerstone Acquisition.

Cornerstone Acquisition

On January 15, 2026, Talen entered into a definitive merger agreement with affiliates of ECP to purchase the 1,120 megawatt ("MW") Lawrenceburg asset located in Indiana, and the 875 MW Waterford and 456 MW Darby assets, both located in Ohio. The Cornerstone Acquisition will substantially expand Talen's presence in the western PJM market and add additional efficient baseload generation assets to our fleet.

The Cornerstone Acquisition is expected to close early in the second half of 2026 and is subject to the satisfaction of customary closing conditions and regulatory approvals from the FERC, Indiana Utility Regulatory Commission and other regulatory agencies. The waiting period pursuant to the Hart-Scott-Rodino Act of 1976 expired in March 2026.

Financing Transactions

In April 2026, Talen Energy Supply ("TES") issued in private placement transactions not involving a public offering, and each at par: (i) $1.5 billion in aggregate principal amount of 6.125% Senior Unsecured Notes due 2031, with interest payable on May 1 and November 1 of each year, and (ii) $2.5 billion in aggregate principal amount of 6.375% Senior Unsecured Notes due 2033, with interest payable on May 1 and November 1 of each year. We intend to use the net proceeds from the issuance and sale of the Senior Unsecured Notes due 2031 and 2033 to fund the previously announced Cornerstone Acquisition and we have used a portion of the net proceeds to redeem Talen's outstanding 8.625% Senior Secured Notes due in 2030. We expect more than an aggregate $40 million of annual interest savings due to lower periodic interest payments: (i) as a result of the 8.625% Senior Secured Notes redemption, and (ii) on the TLBs as a result of a lower secured debt ratio.

Also in April 2026, TES undertook the following financing transactions that are expected to become effective concurrently with the closing of the Cornerstone Acquisition: (i) received commitments to increase its existing RCF (including its revolving LC capacity) from $900 million to $1.35 billion; and (ii) received commitments to upsize its existing $1.1 billion LCF to $1.5 billion and extend the maturity from December 2027 to December 2029.

Balance Sheet and Liquidity

We are focused on maintaining net leverage below our target of 3.5x net debt-to-Adjusted EBITDA. As of March 31, 2026, Talen had ample total available liquidity of approximately $1.9 billion, comprised of $1.0 billion of unrestricted cash and $900 million of available capacity under the revolving credit facility.

Update on Hedging Activities

As of March 31, 2026, including the impact of the Nuclear PTC, we had hedged approximately 85% of our expected generation volumes for 2026, approximately 65% for 2027 and approximately 20% for 2028. Talen's hedging program is a key component of our comprehensive risk policy and supports the objective of increasing cash flow stability while maintaining upside optionality.

Non-GAAP Financial Measures

Adjusted EBITDA and Adjusted Free Cash Flow, which we use as measures of our performance and liquidity, are not financial measures prepared under GAAP. Non-GAAP financial measures do not have definitions under GAAP and may be defined and calculated differently by, and not be comparable to, similarly titled measures used by other companies. Non-GAAP measures are not intended to replace the most comparable GAAP measures as indicators of performance. Generally, a non-GAAP financial measure is a numerical measure of financial performance, financial position, or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP. Management cautions readers not to place undue reliance on the following non-GAAP financial measures, but to also consider them along with their most directly comparable GAAP financial measures. Non-GAAP measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analyzing our results as reported under GAAP.

Adjusted EBITDA

We use Adjusted EBITDA to: (i) assist in comparing operating performance and readily view operating trends on a consistent basis from period to period without certain items that may distort financial results; (ii) plan and forecast overall expectations and evaluate actual results against such expectations; (iii) communicate with our Board of Directors, shareholders, creditors, analysts, and the broader financial community concerning our financial performance; (iv) set performance metrics for our annual short-term incentive compensation; and (v) assess compliance with our indebtedness.

Adjusted EBITDA is computed as net income (loss) adjusted, among other things, for certain: (i) nonrecurring charges; (ii) non-recurring gains; (iii) non-cash and other items; (iv) unusual market events; (v) any depreciation, amortization, or accretion; (vi) mark-to-market gains or losses; (vii) gains and losses on the nuclear facility decommissioning trust ("NDT"); (viii) gains and losses on asset sales, dispositions, and asset retirement; (ix) impairments, obsolescence, and net realizable value charges; (x) interest expense; (xi) income taxes; (xii) legal settlements, liquidated damages, and contractual terminations; (xiii) development expenses; (xiv) noncontrolling interests, except where otherwise noted; and (xv) other adjustments. Such adjustments are computed consistently with the provisions of our indebtedness to the extent that they can be derived from the financial records of the business.

Additionally, we believe investors commonly adjust net income (loss) information to eliminate the effect of nonrecurring restructuring expenses and other non-cash charges, which can vary widely from company to company and from period to period and impair comparability. We believe Adjusted EBITDA is useful to investors and other users of our financial statements to evaluate our operating performance because it provides an additional tool to compare business performance across companies and between periods. Adjusted EBITDA is widely used by investors to measure a company's operating performance without regard to such items described above. These adjustments can vary substantially from company to company and period to period depending upon accounting policies, book value of assets, capital structure, and the method by which assets were acquired.

Adjusted Free Cash Flow

Adjusted Free Cash Flow is utilized by our chief operating decision makers to evaluate cash flow activities. Adjusted Free Cash Flow is computed as Adjusted EBITDA reduced by capital expenditures (including nuclear fuel but excluding development, growth, and (or) conversion capital expenditures), cash payments for interest and finance charges, cash payments for income taxes (excluding income taxes paid from the NDT, taxes paid or deductions taken as a result of strategic asset sales, and benefits of the Nuclear PTC utilized to reduce income taxes paid), and pension contributions.

We believe Adjusted Free Cash Flow is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to determine a company's ability to meet future obligations and to compare business performance across companies and across periods. Adjusted Free Cash Flow is widely used by investors to measure a company's levered cash flow without regard to items such as ARO settlements; nonrecurring development, growth and conversion expenditures; and cash proceeds or payments for the sale or purchase of assets, which can vary substantially from company to company and from period to period depending upon accounting methods, book value of assets, capital structure, and the method by which assets were acquired.
