Cautionary Statements Regarding Forward-Looking Information

This presentation contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are subject to risks and uncertainties. Words such as “could,” “may,” “expects,” “anticipates,” “will,” “targets,” “goals,” “projects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “predicts,” and variations on such words, and similar expressions that reflect our current views with respect to future events and operational, economic, and financial performance, are intended to identify such forward-looking statements. These forward-looking statements include, but are not limited to, statements regarding the acquisition of Calpine Corporation, the pro forma combined company and its operations, strategies and plans, enhancements to investment-grade credit profile, synergies, opportunities and anticipated future performance and capital structure, and expected accretion to earnings per share and free cash flow. Information adjusted for the acquisition should not be considered a forecast of future results.

Forward-looking statements are based on current expectations, estimates and assumptions that involve a number of risks and uncertainties that could cause actual results to differ materially from those projected. The factors that could cause actual results to differ materially from the forward-looking statements made by Constellation Energy Corporation and Constellation Energy Generation, LLC, (the Registrants) include those factors discussed herein, as well as the items discussed in (1) the Registrants’ combined 2025 Annual Report on Form 10-K in (a) Part I, ITEM 1A. Risk Factors, (b) Part II, ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and (c) Part II, ITEM 8. Financial Statements and Supplementary Data: Note 18 — Commitments and Contingencies; (2) the Registrants’ Third Quarter 2026 Quarterly Report on Form 10-Q (to be filed on November 9, 2026) in (a) Part II, ITEM 1A. Risk Factors, (b) Part I, ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and (c) Part I, ITEM 1. Financial Statements: Note 15 — Commitments and Contingencies; and (3) other factors discussed in filings with the SEC by the Registrants.

Investors are cautioned not to place undue reliance on these forward-looking statements, whether written or oral, which apply only as of the date of this presentation. Neither Registrant undertakes any obligation to publicly release any revision to its forward-looking statements to reflect events or circumstances after the date of this presentation.

Slide 3

Non-GAAP Financial Measures

The Registrants report their financial results in accordance with accounting principles generally accepted in the United States (GAAP). Constellation supplements the reporting of financial information determined in accordance with GAAP with certain non-GAAP financial measures, including:

  • Adjusted Operating Earnings (and/or its per share equivalent) exclude certain costs, expenses, gains and losses and other specified items, including adjustments for unrealized gains or losses on economic hedges, interest rate swaps, and fair value adjustments related to gas imbalances and equity investments, decommissioning related activity, asset impairments, certain amounts associated with plant retirements and divestitures, pension and other post-employment benefits (OPEB) non-service credits, and other items as set forth in the Appendix
  • Free cash flow before growth (FCFbG) is cash flows from operations less capital expenditures under GAAP for maintenance and nuclear fuel, equity investments, and adjusted for changes in collateral and non-recurring costs-to-achieve (CTA)
  • Adjusted gross margin is defined as adjusted operating revenues less adjusted purchased power and fuel expense, excluding revenue related to decommissioning, gross receipts tax, variable interest entities, and net of direct cost of sales for certain end-user businesses
    • Adjusted operating revenues excludes the unrealized gains or losses on economic hedging activities due to the volatility and unpredictability of the future changes in commodity prices
    • Adjusted purchased power and fuel excludes the unrealized gains or losses on economic hedging activities and fair value adjustments related to gas imbalances due to the volatility and unpredictability of the future changes in commodity prices
  • Adjusted operating and maintenance (O&M) excludes direct cost of sales for certain end-user businesses, Asset Retirement Obligation (ARO) accretion expense from unregulated units and decommissioning costs that do not affect profit and loss, the impact from operating and maintenance expense related to variable interest entities at Constellation, and other items as set forth in the reconciliation in the Appendix

Due to the forward-looking nature of our Adjusted Operating Earnings guidance, Projected Adjusted Gross Margin, and Projected Free Cash Flow Before Growth, we are unable to reconcile these non-GAAP financial measures to the comparable GAAP measures given the inherent uncertainty required in projecting gains and losses associated with the various fair value adjustments required by GAAP. These adjustments include future changes in fair value impacting the derivative instruments utilized in our current business operations, as well as the debt and equity securities held within our nuclear decommissioning trusts, which may have a material impact on our future GAAP results.

Slide 4

Non-GAAP Financial Measures Continued

This information is intended to enhance an investor’s overall understanding of period over period financial results and provide an indication of Constellation’s operating performance by excluding items that are considered by management to be not directly related to the ongoing operations of the business. In addition, this information is among the primary indicators management uses as a basis for evaluating performance, allocating resources, setting incentive compensation targets and planning and forecasting of future periods.

These non-GAAP financial measures are not a presentation defined under GAAP and may not be comparable to other companies’ presentations of similarly titled financial measures. Constellation has provided these non-GAAP financial measures as supplemental information and in addition to the financial measures that are calculated and presented in accordance with GAAP. These non-GAAP measures should not be deemed more useful than, a substitute for, or an alternative to the most comparable GAAP measures provided in the materials presented.

Non-GAAP financial measures are identified by the phrase “non-GAAP” or an asterisk (*). Reconciliations of these non-GAAP measures to the most comparable GAAP measures are provided in the appendices and attachments to this presentation.

Constellation’s Peak+ Solution Responds to America’s Electricity Needs

Regulators remain focused on how to connect large loads quickly without impacting reliability or increasing consumer costs:

  • Regulatory goals are clear, although rules are not final
  • Customer actions demonstrate that deals can, and will, continue to get done
  • Strong desire to bring new capacity to market quickly

↓ Down arrow

Addressing limited peak hours and increasing grid utilization delivers clear benefits:

  • Historical CCGT capacity factor of ~60% on average represents significant underutilization (1)
  • Utilizing available system capacity can unlock economic growth and save U.S. households $110 - $170 billion over 10 years (2)

Peak+ is an integrated customer solution that combines new capacity to support peak demand growth with energy products tailored to customer needs

  • Addresses a key challenge facing America today: how to manage a small number of peak demand hours while speedily connecting new large loads and making fuller use of the existing grid
  • Supports private investment in new capacity resources to manage the limited number of peak hours
  • Delivers tailored energy products, meeting customer needs while making fuller use of underutilized grid assets

  • Growth outlook excludes potential upside from:
    • Capturing premium value for available nuclear generation in 2029
    • Securing additional natural gas contracts
    • Accretive capital allocation
  • Targeting long-term rolling three-year Base EPS* growth of 10%+

Assets that Cannot be Replicated

  • Largest combined fleet of nuclear, natural gas and geothermal generation in the U.S.
  • Coast-to-coast fleet to support economic growth, electric system reliability and national security
  • New build cost of our ~55 GW fleet would be more than 3x our current enterprise value

Driving Value through Capital Allocation

  • Strong investment grade balance sheet and growing free cash flow* enable our value-enhancing capital allocation framework:
    • Share buyback authorization of $5.0B underscoring confidence in our outlook and executing on our future optionality
    • $3.9B of growth capital in projects at compelling returns
    • Scale that positions us to potentially bring natural gas, storage capacity and new nuclear uprates to the grid in the near term

PTC Provides Support for Nuclear Units When Revenues Fall Below $44.75/MWh (1)

Illustrative Payoff Dynamics for Non-State-Supported Units in 2026

Chart: Market Revenues ($/MWh) versus Market Revenues + PTC ($/MWh). Both axes are labeled from 20 to 60 in increments of 5. Legend: Competitive Unit Payoff; $35/MWh; $47/MWh. The chart notes that PTC provides support from $26.00/MWh to $44.75/MWh (1).

Scenario Market revenues PTC value Total value Tax-adjusted value
$35/MWh $35.00/MWh $7.80/MWh $42.80/MWh $45.40/MWh
$47/MWh $47.00/MWh No PTC value Not stated Not stated
  • The PTC provides support of up to $15.00/MWh for units when revenues are between $26.00/MWh and $44.75/MWh while preserving the ability of the unit to participate in upside from commodity markets.
  • The green line assumes revenues of $47.00/MWh. Since it is above the $44.75/MWh PTC phase-out, units would not receive PTC value.
  • When revenues fall below the $44.75/MWh phase-out, the PTC will provide revenue support for the units, bringing effective realized revenues back to $44.75/MWh.
  • Assuming revenues of $35.00/MWh, the orange line, we would expect units to receive $7.80/MWh PTC, bringing the total value the unit would receive to $42.80/MWh and $45.40/MWh (2) on a tax-adjusted basis.

Slide 17

Nuclear Production Tax Credit Inflation Adjustment (1)

PTC Overview

  • The PTC is in effect through 12/31/2032.
  • In 2026, Constellation qualified for the nuclear PTC up to $15.00/MWh; the PTC amount is reduced by 80% of gross receipts exceeding $26.00/MWh, phasing out completely after $44.75/MWh.
  • The nuclear PTC can be credited against taxes or monetized through sale to an unrelated taxpayer.

PTC Inflation Adjustment

  • In 2026, the maximum PTC and gross receipts threshold are subject to an inflation adjustment based on the GDP price deflator for the preceding calendar year.
  • Inflation Adjustment = (GDP price deflator in preceding year) / (GDP price deflator in 2023)
  • Maximum PTC is rounded to the nearest $2.50/MWh and gross receipts threshold is rounded to the nearest $1.00/MWh.

Footnotes

  1. Volumes are rounded and reflect Constellation’s ownership share of partially owned units.
  2. Revenues above the CMC value are returned to customers.
  3. Capacity revenue for nuclear units is included in the gross receipts calculation for the PTC and therefore should not be incorporated separately into Base Earnings calculations.
  4. Assets to be divested in 2026 are reflected in planning years 2025/2026 and 2026/2027.
  5. Other PJM includes ~400 MWs committed in bilateral agreement that will be available for future capacity auctions.
  6. Base Earnings for fossil/other capacity assumes a clearing price of $200/MWd.
  7. NEMA: Northeastern Massachusetts and Boston; SEMA: Southeastern Massachusetts.
  8. Net Qualifying Capacity excludes batteries and storage and includes ~700 MWs for Geysers that are included in Contracted Clean and therefore should not be incorporated separately into Base Earnings calculations.
