CAUTIONARY NOTE REGARDING FORWARD-LOOKING INFORMATION

This Quarterly Report (this “Report”) contains forward-looking statements concerning expectations, beliefs, plans, objectives, goals, strategies, future events or performance and underlying assumptions and other statements that are not statements of historical fact. These statements often include words such as “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate,” “target,” “project,” “forecast,” “seek,” “will,” “may,” “should,” “could,” “would” or similar expressions. Although we believe that the expectations and assumptions reflected in these forward-looking statements are reasonable, there can be no assurance that these expectations and assumptions will prove to be correct. Forward-looking statements are subject to many risks and uncertainties. The results, events or circumstances reflected in forward-looking statements may not be achieved or occur, and actual results, events or circumstances may differ materially from those discussed in forward-looking statements.

The risks, uncertainties and other factors that could cause actual results to differ materially from the forward-looking statements made by us include those discussed in this Report, as well as the items discussed in our Registration Statement and the included Annual Financial Statements. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Report.

You should not rely on forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this Report primarily on our current expectations and assumptions about future events. Furthermore, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this Report. While we believe such information provides a reasonable basis for these statements, such information may be limited or incomplete, and there can be no assurance that any expectations, assumptions, beliefs or opinions will prove to be correct. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

The forward-looking statements made in this Report relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this Report to reflect events or circumstances after the date of this Report or to reflect new information, actual results, revised expectations or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions or expectations described in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments.

TALEN ENERGY CORPORATION AND SUBSIDIARIES

NOTES TO THE INTERIM FINANCIAL STATEMENTS (UNAUDITED)

Capitalized terms and abbreviations appearing in these Notes to the Interim Financial Statements are defined in the glossary. Dollars are in millions, unless otherwise noted. References to the “Annual Financial Statements” are to the audited Talen Energy Corporation 2023 Annual Financial Statements and Notes thereto, which are attached to the Registration Statement.

“TEC” refers to Talen Energy Corporation. “TES” refers to Talen Energy Supply, LLC. For periods after May 17, 2023, the terms “Talen,” “Successor,” the “Company,” “we,” “us” and “our” refer to TEC and its consolidated subsidiaries (including TES), unless the context clearly indicates otherwise. For periods on or before May 17, 2023, the terms “Talen,” “Predecessor,” the “Company,” “we,” “us” and “our” refer to TES and its consolidated subsidiaries, unless the context clearly indicates otherwise. See “Emergence from Restructuring, Fresh Start Accounting, and Reverse Acquisition” in Note 2 for information on an accounting reverse acquisition that occurred at Emergence.

This presentation has been applied where identification of subsidiaries is not material to the matter being disclosed, and to conform narrative disclosures to the presentation of financial information on a consolidated basis. When identification of a subsidiary is considered important to understanding the matter being disclosed, the specific entity’s name is used. Each disclosure referring to a subsidiary also applies to TEC insofar as such subsidiary’s financial information is included in TEC’s consolidated financial information. TEC and each of its subsidiaries and affiliates are separate legal entities and, except by operation of law, are not liable for the debts or obligations of one another absent an express contractual undertaking to the contrary.

1. Organization and Operations

Talen owns and operates power infrastructure in the United States. We produce and sell electricity, capacity, and ancillary services into wholesale power markets in the United States primarily in PJM and WECC, with our generation fleet principally located in the Mid-Atlantic region of the United States and Montana. The majority of our generation is produced at our zero-carbon nuclear and lower-carbon gas-fired facilities. As of June 30, 2024 (Successor), our generation capacity was 10,665 MW (summer rating). Talen is headquartered in Houston, Texas.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

Our Interim Financial Statements, which are prepared in accordance with GAAP and pursuant to the rules and regulations of the SEC for Quarterly Reports on Form 10-Q, include: (i) the accounts of all controlled subsidiaries; (ii) elimination adjustments for intercompany transactions between controlled subsidiaries; (iii) any undivided interests in jointly owned facilities consolidated on a proportionate basis; and (iv) all adjustments considered necessary for a fair statement of the information set forth. All adjustments are of a normal recurring nature except as otherwise disclosed. Certain information and note disclosures have been condensed or omitted from the Interim Financial Statements in accordance with GAAP. The Consolidated Balance Sheet as of December 31, 2023 (Successor) is derived from the 2023 Consolidated Balance Sheet in the Annual Financial Statements. The Interim Financial Statements and Notes thereto should be read in conjunction with the Annual Financial Statements and Notes thereto. The results of operations presented in our Interim Financial Statements are not necessarily indicative of the results to be expected for the full year or for other future periods because interim period results can be disproportionately influenced by operational developments, seasonality, and other various factors.

Emergence from Restructuring, Fresh Start Accounting, and Reverse Acquisition. In May 2022, TES and 71 of its subsidiaries filed voluntary petitions seeking relief under Chapter 11 of the U.S. Bankruptcy Code. In December 2022, TEC became a debtor in the Restructuring in order to facilitate certain transactions contemplated by the Plan of Reorganization. The Plan of Reorganization was approved by the requisite parties in November 2022, was confirmed by the U.S. Bankruptcy Court in December 2022, and became effective in May 2023, when TEC, TES and the other debtors emerged from the Restructuring.

Upon commencement of the Restructuring, TES was deconsolidated from TEC for financial reporting purposes because TEC no longer controlled TES. TEC regained control of TES at Emergence, which resulted in TEC’s reconsolidation of TES. The combination was accounted for as a reverse acquisition in which TEC was the legal acquirer and TES was the accounting acquirer. Accordingly, our Interim Financial Statements are issued under the name of TEC, the legal parent of TES and accounting acquiree, but represent the continuation of the financial statements of TES, the accounting acquirer.

After Emergence, TES applied fresh start accounting, which resulted in a new basis of accounting as the Company became a new financial reporting entity. As a result of the application of fresh start accounting and the implementation of the Plan of Reorganization, our financial position and results of operations beginning after Emergence are not comparable to our financial position or results of operations prior to that date. The financial results are presented for: (i) the Predecessor period from January 1 through May 17, 2023; and (ii) the Successor periods from May 18 through June 30, 2023, and from January 1 through June 30, 2024. The Interim Financial Statements and Notes thereto have been presented with a black line division to delineate the lack of comparability between the Predecessor and Successor.

See Notes 2, 3 and 4 in Notes to the Annual Financial Statements for additional information on the reverse acquisition, the legal structure of the Restructuring transactions, and the impacts of fresh start accounting.

Summary of Significant Accounting Policies

Reclassifications. Certain amounts in the prior period financial statements were reclassified to conform to the current period’s presentation. The reclassifications did not affect operating income, net income, total assets, total liabilities, net equity or cash flows.

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Treasury Stock and Retirement of Treasury Shares. Share repurchases are accounted for under the cost method, which recognizes the entire cost of the acquired stock, including transaction costs and excise tax, as a reduction in additional paid-in-capital and are presented as “Treasury stock” on the Consolidated Balance Sheets. Share repurchases are recognized on a trade date basis when we are contractually obligated to purchase the shares. At retirement, the common stock balance is reduced for the par value of the shares. The excess of the acquisition cost of treasury shares over the par value is recognized in additional paid-in capital (up to the amount credited to additional paid-in capital upon original issuance of the shares), with any remaining cost deducted from retained earnings.

10

Nuclear PTCs. The Nuclear PTC program provides qualified nuclear power generation facilities with transferable credits for electricity produced and sold to an unrelated party during each tax year. These credits, which are accounted for by analogy to income-based grants under international accounting standards for government grants and disclosure of government assistance, are recognized when there is reasonable assurance that the Company will comply with the applicable conditions and that the credit will be received, which is generally over the period of production. As the credits that are generated each tax year are based on annual gross receipts and production volumes, the measurement of the credit value is estimated at each period until the final value can be determined at the end of the year, which may be different than the estimated amount. The credit value includes a five-times multiplier (up to $15 per MWh) for meeting prevailing wage requirements. Accordingly, Nuclear PTCs are recognized based on production volumes generated during the period and measured at the credit value for the tax year. See Note 4 for amounts recognized, which are presented as “Energy and other revenues” on the Consolidated Statements of Operations and “Other current assets” on the Consolidated Balance Sheets. Credits that are utilized to reduce federal income taxes payable are presented as a reduction of “Other current liabilities” on the Consolidated Balance Sheets. There have been no transfers of Nuclear PTCs to third parties during the six months ended June 30, 2024 (Successor). Additional guidance expected to be issued from the U.S. Treasury and IRS may impact the credit value received.

See Note 2 in Notes to the Annual Financial Statements for additional information on significant accounting policies.

3. Risk Management, Derivative Instruments and Hedging Activities

Risk Management Objectives

We are exposed to risks arising from our business, including, but not limited to, market and commodity price risk, credit and liquidity risk and interest rate risk. The hedging strategies deployed by our commercial organization manage and (or) balance these risks within a structured risk management program in order to minimize near-term future cash flow volatility. Our risk management committee, comprised of certain senior management members across the organization, oversees the management of these risks in accordance with our risk policy. In turn, the risk management committee is overseen by the risk committee of the Board of Directors.

The Board of Directors (including the risk committee) and management have established procedures to monitor, measure and manage hedging activities and credit risk in accordance with the risk policy.

Key risk control activities, which are designed to ensure compliance with the risk policy, include, among other activities, credit review and approval, validation of transactions and market prices, verification of risk and transaction limits, portfolio stress tests, analysis and monitoring of margin at risk and daily portfolio reporting.

Market and Commodity Price Risk. Volatility in the wholesale power markets provides uncertainty in the future performance and cash flows of the business. The price risk Talen is exposed to includes the price variability associated with future sales and (or) purchases of power, natural gas, coal, uranium, oil products, environmental products and other energy commodities in competitive wholesale markets. Several factors influence price volatility, including: seasonal changes in demand; weather conditions; available regional load-serving supply; regional transportation and (or) transmission availability; market liquidity; and federal, regional and state regulations.

Within the parameters of our risk policy, we generally utilize conventional first lien, exchange-traded and over-the-counter traded derivative instruments and, in certain instances, structured products, to economically hedge the commodity price risk of the forecasted future sales and purchases of commodities associated with our generation portfolio.

11

Open commodity purchase (sales) derivatives as of June 30, 2024 (Successor) range in maturity through 2026. The net notional volumes of open commodity derivatives were:

	Successor
	June 30, 2024 (a)	December 31, 2023 (a)
Power (MWh)	(38,172,764)	(27,557,871)
Natural gas (MMBtu)	70,334,960	8,314,060
Emission allowances (tons)	75,000	500,000

__________________

(a)The volumes may be less than the contractual volumes, as the probability that option contracts will be exercised is considered in the volumes displayed.

Interest Rate Risk. Talen is exposed to interest rate risk from the possibility that changes in interest rates will affect future cash flows associated with existing floating rate debt issuances. To reduce interest rate risk, derivative instruments are utilized to economically hedge the interest rates for a predetermined contractual notional amount, which results in a cash settlement between counterparties. To the extent possible, first lien interest rate fixed-for-floating swaps are utilized to hedge this risk.

Open interest rate derivatives are related to the TLB indebtedness and range in maturity dates through 2026. The net notional volumes of open interest rate derivatives were:

	Successor
	June 30, 2024		December 31, 2023
Interest rate (in millions)	$	290	$	290

Credit Risk. Credit risk, which is the risk of financial loss if a customer, counterparty or financial institution is unable to perform or pay amounts due, is applicable to cash and cash equivalents, restricted cash and cash equivalents, derivative instruments and accounts receivable. The maximum amount of credit exposure associated with financial assets is equal to the carrying value. Credit risk, which cannot be completely eliminated, is managed through a number of practices such as ongoing reviews of counterparty creditworthiness, prepayment, inclusion of termination rights in contracts which are triggered by certain events of default and executing master netting arrangements which permit amounts between parties to be offset. Additionally, credit enhancements such as cash deposits, LCs and credit insurance may be employed to mitigate credit risk.

Cash and cash equivalents are placed in depository accounts or high-quality, short-term investments with major international banks and financial institutions. Individual counterparty exposure from over-the-counter derivative instruments is managed within predetermined credit limits and includes the use of master netting arrangements and cash-call margins, when appropriate, to reduce credit risk. Exchange-traded commodity contracts, which are executed through futures commission merchants, have minimal credit risk because they are subject to mandatory margin requirements and are cleared with an exchange. However, Talen is exposed to the credit risk of the futures commission merchants arising from daily variation margin cash calls. Restricted cash and cash equivalents deposited to meet initial margin requirements are held by futures commission merchants in segregated accounts for the benefit of Talen.

Outstanding accounts receivable include those from sales of capacity, generated electricity and ancillary services through contracts directly with ISOs and RTOs and realized settlements of physical and financial derivative instruments with commodity marketers. Additionally, Talen carries accounts receivable due from joint owners for their portion of operating and capital costs for certain jointly owned facilities that are operated by the Company. The majority of outstanding receivables, which are continually monitored, have customary payment terms. The allowance for doubtful accounts was a non-material amount as of June 30, 2024 (Successor) and December 31, 2023 (Successor).

12

As of June 30, 2024 (Successor), Talen’s aggregate credit exposure, which excludes the effects of netting arrangements, cash collateral, LCs and any allowances for doubtful collections, was $437 million and its credit exposure net of such effects was $66 million. Excluding ISO and RTO counterparties, whose accounts receivable settlements are subject to applicable market controls, the ten largest single net credit exposures account for approximately 54% of Talen’s total net credit exposure, which are primarily with entities assigned investment grade credit ratings.

Certain derivative instruments contain credit risk-related contingent features, which may require us to provide cash collateral, LCs or guarantees from a creditworthy entity if the fair value of a liability eclipses a certain threshold or upon a decline in Talen’s credit rating. The fair values of derivative instruments in a net liability position, and that contain credit risk-related contingent features, were non-material as of June 30, 2024 (Successor) and December 31, 2023 (Successor).

Derivative Instrument Presentation

Balance Sheets Presentation. The fair value of derivative instruments presented within assets and liabilities on the Consolidated Balance Sheets were:

Changes in the fair value and realized settlements on commodity derivative instruments are presented as separate components of “Energy revenues” and “Fuel and energy purchases” on the Consolidated Statements of Operations. See Note 12 for additional information on fair value.

Effect of Netting. Generally, the right of setoff within master netting arrangements permits the fair value of derivative assets to be offset with derivative liabilities. As an election, derivative assets and derivative liabilities are presented on the Consolidated Balance Sheets with the effect of such permitted netting as of June 30, 2024 (Successor) and December 31, 2023 (Successor).

Valuation Allowance

Management assesses the available positive and negative evidence to estimate whether it is more likely than not that sufficient future taxable income will be generated to permit use of existing deferred tax assets. The assessment of future taxable income includes the scheduled reversal of taxable temporary differences, projected future taxable income, tax planning strategies and results of recent operations. For the six months ended June 30, 2024 (Successor), Talen recognized a $34 million tax benefit for the reduction in federal and state valuation allowances, primarily related to year-to-date divestitures which increase the amount of tax attributes that can be utilized. See Note 17 for information on the sale transactions. At each period, management will continue to assess the available positive and negative evidence to determine the need for a valuation allowance.

Reliability Impact Assessments

Reliability Impact Assessments. In 2023, Talen provided notifications to PJM it intends to deactivate electric generation at both Brandon Shores and H.A. Wagner on June 1, 2025. PJM has notified Talen that the generation units at each facility are needed for reliability. In April 2024, cost-of-service rate schedules covering the period of June 1, 2025 through December 31, 2028 were filed at FERC for the continued Reliability-Must-Run operation and provision of service from Brandon Shores Units 1 and 2 and H.A Wagner Units 3 and 4. Each of the filed rate schedules sets forth the terms, conditions, and cost-based rates under which the applicable generation facility will agree to continue to operate its generation units. In June 2024: (i) FERC accepted each rate schedule, subject to refund; (ii) an administrative settlement judge was appointed; and (iii) settlement proceedings commenced. No assurance can be provided as to when, if at all, final rate schedules for each generation facility will be approved by FERC or how the rate schedules and resulting revenues may ultimately be modified in the course of settlement judge procedures, or, should they be necessary, in the course of any subsequent evidentiary hearing procedures.

2023 Impairment

Brandon Shores Asset Group. Brandon Shores is required by contract and permit to cease coal combustion by December 31, 2025. In the first quarter of 2023, Talen canceled its plan to convert Brandon Shores to an oil combustion facility due to an increase in expected conversion costs. This decision triggered a recoverability assessment of the carrying value of the Brandon Shores asset group.

The recoverability analysis indicated that the Brandon Shores asset group carrying value exceeded its future estimated undiscounted cash flows, which required an impairment charge to amend the asset group’s carrying value of its property, plant and equipment to its estimated fair value. Accordingly, for the period from January 1 through May 17, 2023 (Predecessor), a $361 million non-cash pre-tax impairment charge on the asset group’s undepreciated property, plant and equipment is presented as “Impairments” on the Consolidated Statements of Operations.

10. Commitments and Contingencies

Legal Matters

Talen is involved in certain legal proceedings, claims and litigation. While we believe that we have meritorious positions and will continue to defend our positions vigorously in these matters, we may not be successful in our efforts. If an unfavorable outcome is probable and can be reasonably estimated, a liability is recognized. In the event of an unfavorable outcome, the liability may be in excess of amounts currently accrued. Because of the inherently unpredictable nature of legal proceedings and the wide range of potential outcomes for any such matter, no estimate of the possible losses in excess of amounts accrued, if any, can be made at this time regarding the matters specifically described below. As a result, additional losses actually incurred in excess of amounts accrued could be substantial.

20

Pending Legal Matters

ERCOT Weather Event Lawsuits. Beginning in March 2021, many power generation facility market participants, including the former Talen subsidiaries that at the time owned the Barney Davis, Nueces Bay and Laredo generation facilities, were sued in multiple Texas courts. In these suits, the plaintiffs: (i) allege, among other things, that they suffered losses due to the generation defendants’ failure to properly prepare their facilities to withstand extreme winter weather and other operational failures during Winter Storm Uri in February 2021, and (ii) seek unspecified compensatory, punitive and other damages. The lawsuits were consolidated into a multi-district litigation (“MDL”) pre-trial court. In January 2023, the court denied a motion to dismiss the MDL filed by the generation defendants. In December 2023, the Texas First Court of Appeals granted the generation defendants’ request for mandamus relief and ordered dismissal of the claims against the generation defendants. The plaintiffs have filed a motion seeking rehearing en banc with the First Court of Appeals. If unsuccessful, the plaintiffs are expected to petition the Texas Supreme Court to review the decision. Plaintiffs asserting prepetition Winter Storm Uri claims are limited to recovering any damages solely from the Talen defendants’ insurers pursuant to the Plan of Reorganization. Certain plaintiffs filed lawsuits asserting Winter Storm Uri claims after commencement of the Restructuring. If any of these post-commencement plaintiffs did not receive effective notice of the Restructuring under applicable bankruptcy law, they may not be subject to the terms of the Plan of Reorganization. Talen cannot predict the outcome of this matter for any such claims or its effect on Talen, which has retained these potential liabilities. See Note 17 for information on Talen’s sale of ERCOT generation assets.

In June 2021, TEC intervened in five cases in which certain market participants are challenging the validity of two Public Utility Commission of Texas (“PUCT”) orders directing ERCOT to ensure energy prices were at their maximum of $9,000 per MWh during Winter Storm Uri. One case has since been dismissed, one case is pending in the Texas Third Court of Appeals and two cases are pending in State District Court in Travis County, Texas. In March 2023, the Third Court of Appeals issued an opinion in Luminant v. PUCT that, in part, reversed and remanded the PUCT orders directing ERCOT to ensure prices were at their maximum of $9,000 per MWh during Winter Storm Uri. The PUCT (along with TEC and others) filed petitions for review with the Texas Supreme Court, which were granted in September 2023. In June 2024, the Texas Supreme Court reversed the judgment of the Texas Third Court of Appeals and affirmed the orders of the PUCT. The Court held that, in issuing its orders, the PUCT substantially complied with the Administrative Procedure Act’s procedural rulemaking requirements. Subject to any successful motion for rehearing in the Texas Supreme Court, this matter is effectively concluded in the Company’s favor.

Resolved Legal Matters

Pension Litigation. In November 2020, four former Talen employees filed a lawsuit in the U.S. District Court for the Eastern District of Pennsylvania against TES, TEC, the TERP, the TERP committee, and (as amended) ten former retirement plan committee members alleging that they are owed enhanced benefits under the TERP. In September 2023, the parties reached an agreement to settle all claims on a class-wide basis, inclusive of attorneys’ fees, in exchange for $20 million. The settlement was approved by the court and became final by its terms in July 2024. Approximately $14 million of the settlement will be paid by the TERP to class members, with the remainder paid by the Company, net of insurance recoveries, to the plaintiffs’ attorneys and for certain administrative costs of the settlement. TES, at its discretion, may elect to fund a contribution into the TERP to cover settlement payments paid by the TERP. The settlement amounts and the expected insurance recoveries are presented on the Consolidated Balance Sheets as of June 30, 2024.

See Note 12 in Notes to the Annual Financial Statements for additional resolved legal matters.

21

Regulatory Matters

Talen is subject to regulation by federal and state agencies and other bodies that exercise regulatory authority in the various regions where we conduct business, including but not limited to: FERC; the Department of Energy; the Federal Communications Commission; the NRC; NERC; public utility commissions in various states in which we conduct business; and RTOs and ISOs in the regions in which we conduct business. Talen is party to proceedings before such agencies arising in the ordinary course of business and has other regulatory exposure due to new or amended regulations promulgated by such agencies from time to time. While the outcome of these regulatory matters and proceedings is uncertain, the likely results are not expected, either individually or in the aggregate, to have a material adverse effect on our financial condition or results of operations, although the effect could be material to our results of operations in any interim reporting period.

Susquehanna ISA Amendment. In June 2024, PJM filed at FERC an Amended Interconnection Service Agreement (“Amended ISA”) executed by PJM, PPL Electric Utilities Corporation (“PPL Electric,” a subsidiary of PPL), and Susquehanna, to enable Susquehanna to decrease the amount of power it will provide to the grid and thus increase, up to 480 MW, power that can be sold and provided directly to load via transmission owned by that load and connected directly to Susquehanna (and not to the power grid). The current Interconnection Service Agreement, previously accepted by FERC and similarly approved and executed by PJM and PPL Electric, already allows Susquehanna to decrease power to the grid by up to 300 MW in order to sell and provide that power to load. The increase to 480 MW was studied by PJM, which confirmed that such increase would have no reliability impacts on the grid. PJM requested an effective date of August 3, 2024 for the Amended ISA filing. In June 2024, Exelon Corporation and AEP filed a protest, despite the Amended ISA not being in their service territories and despite PPL Electric’s agreement to the terms. The protest raised generic issues about the service of load behind generators and requests that FERC set the Amended ISA proceeding for hearing or, in the alternative, reject the filing. Talen believes nearly all issues raised by Exelon Corporation and AEP are not within FERC’s limited jurisdictional review and lack merit, and Talen intends to defend against them quickly and vigorously. In July 2024, Talen filed responses at FERC opposing the aforementioned protest and urging FERC to accept the Amended ISA. In August 2024, FERC issued a deficiency letter seeking a more information about the Amended ISA. Talen will work closely with PJM and PPL to respond quickly to the deficiency letter. Additionally, in a separate order, FERC opened a new proceeding through which it will hold a commissioner-led technical conference in Fall 2024 to discuss generic issues related to the co-location of large loads. Talen intends to fully participate in that process.

PJM MOPR. In July 2021, PJM filed proposed tariff language to significantly reduce the application of the existing PJM MOPR by applying it only when the state requires an entity to act in a certain manner in the capacity market in exchange for receiving a subsidy. FERC did not act on PJM’s July 2021 filing, and the PJM MOPR tariff language went into effect in September 2021. In December 2023, the U.S. Court of Appeals for the Third Circuit denied the petitions for review of the MOPR tariff language. In March 2024, the Public Utilities Commission of Ohio filed at the U.S. Supreme Court a petition for certiorari asking the Court to review the Third Circuit’s December 2023 order, which the U.S. Supreme Court denied in May 2024. The final impacts on Talen’s financial condition, results of operations and liquidity are not known at this time.

PJM Market Seller Offer Cap. In March 2021, FERC responded to complaints filed by the PJM IMM on behalf of PJM and various consumer advocates alleging that the PJM MSOC was above a competitive offer level and was, therefore, unjust and unreasonable. In September 2021, FERC issued an order requiring the PJM ACR for each generator to be determined administratively by the PJM IMM. In August 2023, the U.S. Court of Appeals for the District of Columbia Circuit denied petitions by Talen and others for review of FERC’s order. In January 2024, the Electric Power Supply Association filed at the U.S. Supreme Court a petition for certiorari asking the Court to review the D.C. Circuit’s August 2023 order, which the U.S. Supreme Court denied in May 2024. The final impacts of this order on Talen’s financial condition, results of operations and liquidity are not known at this time.

22

PJM Capacity Market Reform. In February 2023, the PJM Board of Managers directed PJM and its stakeholders to resolve: (i) key issues that address the energy transition taking place in PJM; and (ii) issues observed from Winter Storm Elliott. The PJM Board of Managers directive included reliability risks, risk drivers and resource availability. The stakeholder process is referred to as Critical Issue Fast Path (“CIFP”) on resource adequacy. In October 2023, PJM made two filings at FERC regarding certain capacity market reforms developed through the CIFP process. In January 2024, FERC accepted one of PJM’s filings, subject to the condition that PJM submit a compliance filing within 30 days. However, in February 2024, FERC rejected the second of PJM’s capacity market reform filings and approved a request from PJM for a 35-day delay of Base Residual Auction. PJM held the Base Residual Auction for the 2025/2026 Delivery Year in July 2024. At this time, Talen cannot fully predict the impacts of PJM’s reforms on its operations and liquidity.

In June 2023, FERC accepted a request by PJM to delay certain PJM Base Residual Auctions in order to propose additional changes to the PJM RPM. The delay scheduled the PJM Base Residual Auctions for 2026/2027 in December 2024, for 2027/2028 in June 2025, and for 2028/2029 in December 2025. Although PJM has established dates for the next three auctions, there is no guarantee that the auctions will take place on those dates or at all. Depending on the ultimate outcome of matters related to PJM’s capacity auctions, capacity revenues in PJM could be affected, but the final impacts on Talen’s financial condition, results of operations and liquidity are not known at this time.

Environmental Matters

Extensive federal, state and local environmental laws and regulations are applicable to our business, including those related to air emissions, water discharges, and hazardous and solid waste management. From time to time, in the ordinary course of our business, Talen may become involved in other environmental matters or become subject to other, new or revised environmental statutes, regulations or requirements. It may be necessary for us to modify, curtail, replace or cease operation of certain facilities or performance of certain operations to comply with statutes, regulations and other requirements imposed by regulatory bodies, courts or environmental groups. We may incur costs to comply with environmental laws and regulations, including increased capital expenditures or operation and maintenance expenses, monetary fines, penalties or other restrictions, which could be material. Legal challenges to environmental permits or rules add to the uncertainty of estimating the future cost of complying with these permits and rules. In addition, costs may increase significantly if the requirements or scope of environmental laws or regulations, or similar rules, are expanded or changed.

Water and Waste. Changes made by the EPA to the EPA CCR Rule and the EPA ELG Rule in 2020 allow coal generation facility operators to request an extension to compliance deadlines if the facility commits to cessation of coal-fired generation by the end of 2028. Pursuant to Talen’s plans to cease wholly owned coal operations, Talen requested extensions for compliance under these rules for certain of its generation facilities; some have been approved and some are still under review. The most significant extension under review is the EPA CCR Rule Part A extension request for Montour Ash Impoundment 1, and a negative result would have a significant impact on the closure plan for this impoundment.

In 2023, the EPA proposed additional changes to the EPA ELG Rule and the EPA CCR Rule and finalized those changes in May 2024. The new EPA ELG Rule does not add treatment requirements to Talen’s coal-fired power generation facilities planning to cease burning coal by 2028, but it does establish discharge limits for waters collected from CCR units. Under the revised EPA CCR Rule, the EPA developed new categories of CCR units which are areas that were previously unregulated. These new CCR units, which are subject to the closure performance standards set by the EPA, are: (i) legacy CCR impoundments; and (ii) areas where CCR was disposed of or managed on land outside of regulated units called CCR management units (subject to a minimum threshold). Furthermore, the EPA’s interpretations of the EPA CCR Rule continue to evolve through litigation, enforcement, and other regulatory actions.

23

Talen submitted formal comments on both proposed rules citing their flaws. A number of challenges against the EPA ELG Rule have been filed in multiple U.S. Courts of Appeals. The various challenges have been filed by 15 state attorneys general, environmental groups, and industry parties and groups, including the Utility Water Act Group (“UWAG”), of which Talen is a member. In June 2024, the U.S. Court of Appeals for the Eighth Circuit was selected to hear the consolidated petitions for review and UWAG filed a motion to stay the EPA ELG Rule during the pendency of the litigation.

Multiple parties have filed challenges to the EPA CCR Rule in the U.S. Court of Appeals for the District of Columbia, including USWAG”), of which Talen is a member. It is uncertain at this time whether the revised Rules will withstand the filed and anticipated legal challenges by power producers, industry groups, state attorneys general, and others.

The Company continues to review the rule’s provisions, perform the required applicability assessments, and await additional information and guidance from the EPA in order to sufficiently interpret the rule’s requirements. Accordingly, as of June 30, 2024 (Successor), the Company did not have sufficient information to determine the scope of work required under the rule’s provisions and associated estimates. As the Company completes its assessment and determines the scope of work on its properties imposed by the new rule, new AROs and (or) revisions to existing AROs could be required. Such AROs could be material, and as a result, may have a material impact on our results of operations and financial condition.

Air. Since 2016, the coal-fired generation facilities in which Talen has ownership, including Brunner Island, Montour, Keystone and Conemaugh, have been the subject of various efforts under the Clean Air Act to strengthen applicable nitrogen oxides (“NOx”) emission limits. These include Section 126 petitions by downwind states, recommendations by the Ozone Transport Commission, and a ruling on Pennsylvania’s Reasonably Available Control Technology (“RACT”) 2 program by the U.S. District Court for the Southern District of New York. Although the petitions and recommendations are not withdrawn, open concerns appear to have been addressed by the EPA’s issuance of a federal implementation plan with short-term RACT2 NOx limits at these plants in 2022 (resulting from the above court case) (“2022 NOx RACT2 FIP”) and the EPA’s “Good Neighbor Plan FIP” issued in June 2023. Both the 2022 NOx RACT2 FIP and the Good Neighbor Plan FIP are further discussed below. Concerns by upwind states regarding NOx controls were not limited to coal plants owned by Talen.

Although EPA’s 2022 NOx RACT2 FIP for Pennsylvania, which Talen supported, was challenged by other parties, on May 2, 2024, the U.S. Court of Appeals for the Third Circuit upheld the 2022 NOx RACT2 FIP, and the Pennsylvania DEP has now proposed a new state implementation plan (“SIP”) that is consistent with the 2022 NOx RACT2 FIP. In November 2022, Pennsylvania finalized its NOx RACT3 standards for all power generation facilities to address the EPA’s 2015 Ozone Standard. Affected Talen facilities have submitted permit applications demonstrating their compliance methods. At this time, Talen cannot predict the outcome of these potential rule changes on the operations of its generation facilities and its results of operations.

Further, to address the EPA’s 2015 Ozone Standard, in June 2023, the EPA published a final rule covering the EPA CSAPR ozone season NOx allowance trading program for 2023 and beyond. The final rule is known as the Good Neighbor Plan FIP. The EPA made some reductions in allowance allocations, among other changes, to minimize NOx emissions during the Ozone Season. Talen’s plants in Texas had originally been covered by the Good Neighbor Plan FIP; however, Talen sold its Texas facilities in the second quarter of 2024 and therefore is no longer impacted by the rule in Texas. Talen’s facilities in Maryland, Pennsylvania and New Jersey remain subject to the new rule; however, the entire rule has been challenged by multiple parties, and the Good Neighbor Plan FIP was stayed in its entirety by the U.S. Supreme Court in June 2024 pending a complete review of the rule by the U.S. Court of Appeals for the D.C. Circuit. At this time, Talen cannot predict the long-term outcome of these rule changes on the operations of its generation facilities and its results of operations.

24

The EPA MATS Rule, which is the original EPA NESHAP for coal plants, has been in effect since 2012. In April 2023, the EPA proposed, and in May 2024, finalized, its Risk and Technology Review for coal-fired generation facilities under the EPA NESHAP. The final rule most notably requires coal plants to reduce particulate matter (“PM”) emissions by the end of 2027 (or 2028 in certain circumstances). Colstrip cannot meet the new PM standard without substantial upgrades to its control equipment; therefore, Talen and the Colstrip co-owners face the decision either to invest in new cost-prohibitive control equipment or retire the plant. That decision must be made in conjunction with compliance requirements under EPA’s new GHG Rule, finalized in May 2024.

Talen submitted formal comments on the new PM standard and revisions to the EPA MATS Rule, citing the rule’s flaws. A number of challenges to the EPA MATS Rule have been filed in the U.S. Court of Appeals for the D.C. Circuit, including challenges by Talen and by 23 state attorneys general. Multiple motions to stay the EPA MATS Rule during the pendency of the litigation have been filed by Talen and other parties, and in August 2024 the stay motions were denied. In light of the on-going legal challenges, Talen cannot predict the full impact of the revised EPA MATS Rule on the operations of its coal-fired generation facilities and its results of operations.

RGGI. In April 2022, Pennsylvania formally entered the RGGI program, with compliance set to begin on July 1, 2022. However, certain third parties filed lawsuits and appeals questioning the legality of the regulation and the implementation of RGGI in Pennsylvania was stayed. In November 2023, the Commonwealth Court of Pennsylvania ruled RGGI was an invalid tax and voided the rulemaking. The Pennsylvania Department of Environmental Protection appealed this decision to the Pennsylvania Supreme Court in November 2023, and the following day filed notice with the court that the RGGI program would not be implemented while the appeal is pending. In July 2024, the Pennsylvania Supreme Court permitted certain non-profit environmental groups (including Citizens for Pennsylvania’s Future, Clean Air Council, Sierra Club, and the Environmental Defense Fund) to intervene in the litigation. At this time, Talen is unable to determine the full impact of the RGGI program, when and if implemented, on its results of operations and liquidity.

Federal Climate Change Actions. The current federal administration has identified climate change policy as a priority that includes, but is not limited to, greenhouse gas (“GHG”) emission reductions. In May 2024, the EPA issued a new rule under the Clean Air Act that establishes New Source Performance Standards for new electric generating units and GHG Emissions Guidelines for existing electric generating units (“EGUs”) for state implementation. The guidelines would allow all existing EGUs to continue to operate until at least the end of 2031 without having to meet new GHG limits. Existing oil/gas steam EGUs (for example, Martins Creek) will not require additional controls at this time. However, if existing coal-fired EGUs (for example, Colstrip) are to be able to operate beyond 2031, they must install a GHG reduction technology, like carbon capture and sequestration (CCS), by the end of 2031. Talen will need to evaluate the viability and costs of additional controls and decide whether to invest in those controls at Colstrip or retire the units. That decision may be influenced by the cost of compliance with the revised EPA MATS Rule. The EPA stated that it chose not to finalize emission guidelines for existing fossil fuel-fired combustion turbines (for example, Lower Mt. Bethel); however, the EPA intends to take further action on such emission guidelines at a later date.

In 2023, Talen submitted formal comments on the proposed EPA GHG Rule, citing the rule’s flaws. A number of petitions for review of the EPA GHG Rule have been filed in the U.S. Court of Appeals for the D.C. Circuit, including by coalitions representing 27 states and an ad hoc coalition of power producers, of which Talen is a member. Various parties, including the ad hoc coalition of power producers that includes Talen, filed motions to stay the EPA GHG Rule during the pendency of the litigation; however, in July 2024, the D.C. Circuit denied the motions to stay the rule. Shortly thereafter, the coalition of West Virginia and 24 other states and other petitioners, including the ad hoc coalition of power producers that includes Talen, filed at the U.S. Supreme Court requests for an emergency stay of the EPA GHG Rule. If the rule withstands these legal challenges by power producers (including Talen), industry groups, state attorneys general, and others, the EPA GHG Rule could materially impact Colstrip and Talen. Talen is currently evaluating that potential impact. At this time, Talen cannot predict the full impact of the EPA GHG Rule on the operations of its coal-fired generation facilities and its results of operations.

25

Environmental Remediation. From time-to-time, Talen undertakes investigative or remedial actions in response to notices of violations, spills or other releases at various on-site and off-site locations, negotiates with the EPA and state and local agencies regarding actions necessary for compliance with applicable requirements, negotiates with property owners and other third parties alleging impacts from our operations and undertakes similar actions necessary to resolve environmental matters that arise in the course of normal operations.

Future investigation or remediation work at sites currently under review, or at sites not currently identified, may result in additional costs, but at this time we are unable to determine if such investigation or remediation work will have a material adverse effect on our financial condition or results of operations. 

Guarantees and Other Assurances

In the normal course of business, Talen enters into agreements that provide financial performance assurance to third parties on behalf of certain subsidiaries. These agreements primarily support or enhance the creditworthiness attributed to a subsidiary on a stand-alone basis or facilitate the commercial activities in which these subsidiaries engage. Such agreements may include guarantees, stand-by LCs issued by financial institutions, surety bonds issued by insurance companies, and indemnifications. In addition, they may include customary indemnifications to third parties related to asset sales and other transactions. Based on our current knowledge, the probability of expected material payment/performance for the guarantees and other assurances is considered remote.

Surety Bonds. Surety bonds provide financial performance assurance to third parties on behalf of certain subsidiaries for obligations including, but not limited to, environmental obligations and AROs. In the event of nonperformance by the applicable subsidiary, the beneficiary would make a claim to the surety, and the Company would be required to reimburse any payment by the surety. Talen’s liability with respect to any surety bond is released once the obligations secured by the surety bond are performed. Surety bond providers generally have the right to request additional collateral or request that such bonds be replaced by alternate surety providers, in each case upon the occurrence of certain events. As of June 30, 2024 (Successor) and December 31, 2023 (Successor), the aggregate amount of surety bonds outstanding was $235 million and $240 million, respectively, including surety bonds posted on behalf of Talen Montana as discussed below.

Talen Montana Financial Assurance. Pursuant to the Colstrip AOC, Talen Montana, in its capacity as the Colstrip operator, is obligated to close and remediate coal ash disposal impoundments at Colstrip. The Colstrip AOC specifies an evaluation process between Talen Montana and the Montana Department of Environmental Quality (“the MDEQ”) on the scope of remediation and closure activities, requires the MDEQ to approve such scope, and requires financial assurance to be provided to the MDEQ on approved plans. Each of the co-owners of the Colstrip Units have provided their proportional share of financial assurance to the MDEQ for estimates of coal ash disposal impoundments remediation and closure activities approved by the MDEQ.

TES has posted an aggregate $125 million of surety bonds to the MDEQ on behalf of Talen Montana’s proportional share of remediation and closure activities as of June 30, 2024 (Successor) and $115 million as of December 31, 2023 (Successor). In April 2024, the MDEQ approved a modified work scope that required Talen Montana to post an additional $7 million of surety bonds or other financial assurance in the second quarter 2024. Talen Montana has agreed to reimburse TES and its affiliates in the event that these surety bonds are called. Talen Montana’s surety bond requirements may increase due to scope changes, cost revisions and (or) other factors when the MDEQ conducts annual reviews of approved remediation and closure plans as required under the Colstrip AOC. The surety bond requirements will decrease as Colstrip’s coal ash impoundments remediation and closure activities are completed.

Cumulus Digital Assurances. As of December 31, 2023 (Successor), TES had issued LCs in the aggregate amount of $50 million to the lenders of the Cumulus Digital TLF, which LCs could be drawn upon, among other events, the acceleration of the loan due to a bankruptcy or other event of default by Cumulus Digital. The LCs were cancelled upon the repayment in full of the Cumulus Digital TLF in March 2024.

26

Additionally, TEC had provided a guarantee to the lenders under the Cumulus Digital TLF for certain shortfalls in interest and principal payments by Cumulus Digital (up to a maximum of 23% of the principal amount of outstanding loans thereunder). The guarantee was cancelled upon the payment in full of the Cumulus Digital TLF in March 2024.

Other Commitments and Contingencies

Nuclear Insurance. The Price-Anderson Act is a United States federal law that governs liability-related issues and ensures the availability of funds for public liability claims arising from a nuclear incident at any U.S. licensed nuclear facility. It also seeks to limit the liability of nuclear reactor owners for such claims from any single incident. As of June 30, 2024 (Successor), the liability limit per incident is $16.3 billion for such claims, which is funded by insurance coverage from American Nuclear Insurers (approximately $500 million in coverage), with the remainder covered by an industry retrospective assessment program.

As of June 30, 2024 (Successor), under the industry retrospective assessment program, in the event of a nuclear incident at any of the reactors covered by the Price-Anderson Act, Susquehanna could be assessed deferred premiums of up to $332 million per incident, payable at a maximum of $49 million per year.

Additionally, Susquehanna purchases property insurance programs from Nuclear Electric Insurance Limited (“NEIL”), an industry mutual insurance company of which Susquehanna is a member. As of June 30, 2024 (Successor), facilities at Susquehanna are insured against nuclear property damage losses up to $2 billion and non-nuclear property damage losses up to $1 billion. Susquehanna also purchases an insurance program that provides coverage for the cost of replacement power during prolonged outages of nuclear units caused by certain specified conditions.

Under the NEIL property and replacement power insurance programs, Susquehanna could be assessed retrospective premiums in the event of the insurers’ adverse loss experience. The maximum assessment for this premium is $48 million as of June 30, 2024 (Successor). Talen has additional coverage that, under certain conditions, may reduce this exposure.

Talen Montana Fuel Supply. Talen Montana purchases coal from the Rosebud Mine for its interest in Colstrip Units 3 and 4 under a full requirements contract with an unaffiliated coal mine operator. In 2015, the MDEQ issued the mine operator an amendment to one of its mine permits expanding the area authorized for mining. Certain parties challenged the permit amendment in a proceeding at the Montana Board of Environmental Review (“the MBER”) and, after the MBER issued a decision upholding the permit amendment, in a lawsuit in Montana state district court. In January 2022, the district court entered an order vacating the permit amendment effective April 1, 2022. Rosebud Mining ceased mining in the expansion area prior to the April 1, 2022 deadline. The mine operator and the MDEQ appealed the district court’s decisions to the Montana Supreme Court and filed motions seeking to stay the order vacating the permit. In August 2022, the Montana Supreme Court entered an order staying the district court’s order pending resolution of the appeal. In November 2023, the Montana Supreme Court remanded the case to the MBER to reanalyze the administrative record, resolve factual questions, and re-examine its prior conclusion. The MBER is awaiting remand. In the meantime, however, the Montana Supreme Court reinstated vacatur of the permit amendment pending MBER review.

In May 2022, the MDEQ issued a second permit amendment expanding the area authorized for mining by the coal-mine operator. A group of complainants initiated proceedings at the MBER and in Montana state district court challenging the second permit amendment. Summary judgment briefing was completed in the MBER case as of January 2024. In December 2023 the Montana state district court challenge was stayed for six months pending a ruling from the Montana Supreme Court in analogous cases.

27

In September 2022, the Montana Federal District Court entered an order upholding challenges to a third permit amendment expanding the area authorized for mining by the mine operator. The plaintiffs asserted that the U.S. Office of Surface Mining Reclamation and Enforcement (the “OSM”) violated the National Environmental Policy Act (“NEPA”) when preparing the Environmental Impact Statement (“the EIS”) for the permit amendment. The court ordered the OSM to complete an updated the EIS in accordance with NEPA’s requirements. The permit amendment will be vacated unless the OSM completes the updated the EIS within 19 months from the date of the court’s order. The federal defendants did not appeal and expect to issue a revised decision on the permit amendment within the 19-month deadline, but in November 2022, intervenor-defendants, Westmoreland Rosebud and International Union, appealed the ruling to the Ninth Circuit Court of Appeals. Montana Environmental Information Center and the other plaintiffs moved to dismiss the appeal for lack of jurisdiction, and the federal defendants did not oppose the motion to dismiss. The appeal was dismissed in November 2023, and the federal defendants requested an extension of the deadline to complete the updated EIS until June 30, 2025. In April 2024, the District Court granted an extension, but only to January 31, 2025.

At this time, Talen cannot predict the outcome of these matters or their effect on Talen Montana’s operations, results of operations or liquidity.

17. Acquisitions and Divestitures

Completed Divestitures

ERCOT Sale. In March 2024, the Company and CPS Energy entered into an agreement for CPS Energy to acquire the Company’s 1,710 MW Texas generation portfolio located within the ERCOT market for $785 million, subject to customary net working capital adjustments. The sale closed in May 2024. A gain on sale of $563 million is presented as “Gain (loss) on sale of assets, net” on the Consolidated Statements of Operations.

Cumulus Data Campus Sale. In March 2024, AWS purchased substantially all the assets of Cumulus Data and certain other assets for gross proceeds of $650 million. Gross proceeds of $350 million were initially received at closing with the remaining $300 million of variable consideration, presented as “Other current assets” on the Consolidated Balance Sheets, expected to be received from escrow at the completion of certain development milestones. Cumulus Digital Holdings distributed $109 million of the initial net proceeds from the sale to its members, including $108 million to TES.

In connection with the Cumulus Data Campus Sale, the Company entered into a power purchase agreement with AWS, pursuant to which (i) the Company agreed to supply up to 960 MW of long-term, carbon-free power to the Cumulus Data Campus from Susquehanna; (ii) the parties agreed to fixed-price power commitments that increase in 120 MW increments over several years; and (iii) AWS, under certain conditions, has the option to cap their commitments at 480 MW. AWS also became lessor under the ground lease agreement with Nautilus.

For the six months ended June 30, 2024 (Successor), a $324 million net gain on sale is presented as “Gain (loss) on sale of assets, net” on the Consolidated Statements of Operations.

Pennsylvania Minerals Divestiture. In March 2023, Talen sold certain mineral interests located in Pennsylvania for $29 million, while preserving the right to certain royalty payments from existing and future producing natural gas wells. For the period from January 1 through May 17, 2023 (Predecessor), a $29 million gain was presented as “Gain (loss) on sale of assets, net” on the Consolidated Statements of Operations.

Western Gas Book Divestiture. In April 2023, Talen sold certain contracts relating to the transportation of natural gas in the southwestern United States for approximately $15 million. For the period from January 1 through May 17, 2023 (Predecessor), a $15 million gain was presented as “Gain (loss) on sale of assets, net” on the Condensed Consolidated Statements of Operations.

35

Acquisition of Noncontrolling Interests

In March 2024, TES acquired all of the equity units of Cumulus Digital Holdings held by affiliates of Orion and two former members of Talen senior management in exchange for an aggregate of $39 million. Following these transactions, TES owns 100% of the equity of Cumulus Digital Holdings.

18. Segments

Talen’s operating segments are based on the market areas in which our generation facilities operate and reflect the manner in which our chief operating decision maker review results and allocate resources. Adjusted EBITDA is the key profit metric used to measure financial performance of each segment. Total assets or other asset metrics are not considered a key metric or reviewed by the chief operating decision makers.

“PJM” is engaged in electricity generation, marketing activities, commodity risk and fuel management within the PJM RTO or ISO markets and is comprised of Susquehanna and Talen’s natural gas and coal generation facilities.

“Other” represents a non-reportable segment that includes the operating and marketing activities of Talen Montana’s proportionate share of the Colstrip Units in the WECC market, the operating activities of Nautilus, and other non-material operating and development activities. The Other segment also included the operating activities of our Texas power generation facilities in the ERCOT market prior to their disposal in May 2024. We have determined it appropriate to aggregate results of Talen’s remaining non-reportable segments and other operating activities.

“Corporate and Eliminations” represents a non-reportable segment represents the remaining grouping that includes: (i) General and administrative expenses incurred by our corporate and commercial functions that are not allocated to our reportable segments; (ii) other non-material components that are not regularly reviewed by our chief operating decision maker; and (iii) intercompany eliminations. This grouping is presented to reconcile the reportable segments to our consolidated results.

Financial data for the segments and reconciliation to consolidated results are:

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the Interim Financial Statements, the Annual Financial Statements, and their accompanying notes. In addition, the following discussion contains forward-looking statements, which involve risks and uncertainties. See “Cautionary Note Regarding Forward-Looking Information” for additional information on forward-looking statements. Capitalized terms and abbreviations are defined in the glossary. Dollars are in millions, unless otherwise noted.

Overview

Talen owns and operates power infrastructure in the United States. We produce and sell electricity, capacity, and ancillary services into wholesale power markets in the United States primarily in PJM and WECC, with our generation fleet principally located in the Mid-Atlantic region of the United States and Montana. The majority of our generation is produced at our zero-carbon nuclear and lower-carbon gas-fired facilities. As of June 30, 2024 (Successor), our generation capacity was 10,665 MW (summer rating). Talen is headquartered in Houston, Texas.

Recent Developments

Common Stock Transactions

In the six months ended June 30, 2024 (Successor), the company repurchased a total of 5,773,889 shares of the Company’s common stock under the share repurchase program for an aggregate purchase price of $661 million, inclusive of transaction costs and excise taxes, at a weighted average per share price of $114.48. Of the total shares repurchased, 5,275,862 shares were the result of the tender offer executed in June 2024.

In June 2024, the Company retired 5,768,862 shares of treasury stock repurchased during the six months ended June 30, 2024 (Successor).

In July 2024, the Company repurchased 2,413,793 shares from affiliates of Rubric Capital Management LP at a purchase price of $116.00 per share for an aggregate purchase price of $280 million and retired the shares. There were de minimis transaction costs associated with this repurchase.

In July 2024, a former executive exercised equity-classified warrants to 457,142 shares of the Company’s common stock in a non-cash transaction. After giving effect to tax impacts, the Company issued 160,289 shares of the Company’s common stock.

As of August 13, 2024, the Company has 51,001,450 shares of common stock outstanding.

See Note 15 in Notes to the Interim Financial Statements for more information related to share repurchases and the retirement of treasury stock.

PJM 2025/2026 Base Residual Auction

In July 2024, PJM reported the results of the PJM Base Residual Auction for the 2025/2026 planning year. Talen cleared a total of 6,820 MW at a clearing price of $269.92 per MW-day for the MAAC, PPL, and PSEG locational deliverability areas.

Remarketing of PEDFA Bonds

In June 2024, the Company completed the remarketing of $50 million in aggregate principal amount of its PEDFA 2009B and $81 million in aggregate principal amount of its PEDFA 2009C Bonds. The bonds will bear interest at 5.25% until the end of the new term rate period on June 1, 2027. In connection with the remarketing, $133 million of LCs issued under the TLC LCF that had previously supported the bonds were terminated, providing the Company with increased LC capacity under the TLC LCF.

38

Term Loan Repricing

In May 2024, the Company completed a repricing transaction with respect to the TLB and TLC. The new rate applicable to the TLB and TLC is SOFR plus 350 basis points, which reduces the interest rate margin by 100 basis points. The applicable SOFR floor was reduced from 50 to 0 basis points. Additionally, in connection with the repricing, the lenders under the TLB and TLC agreed to: (i) waive any mandatory prepayment obligations in connection with the ERCOT Sale; and (ii) certain other amendments permitting Talen additional capacity for dispositions, restricted payments and investments under the Credit Agreement.

ERCOT Sale

In March 2024, the Company and CPS Energy entered into an agreement for CPS Energy to acquire the Company’s 1,710 MW Texas generation portfolio located within the ERCOT market for $785 million, subject to customary net working capital adjustments. The sale closed in May 2024. A net gain of $563 million is presented as “Gain (loss) on sale of assets, net” on the Consolidated Statements of Operations.

Factors Affecting Our Financial Condition and Results of Operations

Earnings in future periods are subject to various uncertainties and risks. See “Cautionary Note Regarding Forward-Looking Information” and Notes 3 and 10 in Notes to the Interim Financial Statements for additional information on our risks.

Generation Facility Updates

Reliability Impact Assessments. In the first quarter 2023, the project to convert Brandon Shores’ fuel source from coal to fuel oil was canceled for economic reasons, which resulted in non-cash impairment charges related to property, plant, and equipment and inventories. In April 2023, Brandon Shores notified PJM that it will deactivate electric generation on June 1, 2025. In June 2023, PJM notified Brandon Shores that its generation Units 1 and 2 are needed for transmission reliability. In October 2023, for economic reasons, the Company provided a notice to PJM that it intends to deactivate H.A. Wagner on June 1, 2025. In January 2024, PJM notified H.A Wagner that its generation Units 3 and 4 are needed for transmission reliability.

Each generation facility has filed a cost-of-servicer rate schedule at FERC, which was accepted in June 2024, subject to refund. Additionally, an administrative settlement judge was appointed in June 2024 and settlement proceedings have commenced. No assurance can be provided as to when, if at all, a final rate schedule will be approved by FERC or how the rate schedule and resulting revenues may be modified in the course of settlement judge procedures, or, should they be necessary, in the course of any subsequent evidential hearing. See Note 8 in Notes to the Interim Financial Statements for additional information on the reliability assessments and additional information on the Brandon Shores impairment.

Commodity Markets

The following tables summarize average on-peak power prices and natural gas prices for the PJM market for the three months ended June 30, 2024 (Successor) and 2023 (Predecessor). During the second quarter of 2024, natural gas prices for Texas Eastern M-3 settled below its ten-year average resulting from storage levels above the five-year range and ample supply. In PJM, higher than normal temperatures during the quarter contributed to increased power load resulting in higher settled on-peak power prices compared to the same period in the prior year.

PJM. The average settled market prices for the three months ended June 30 were:

	2024		2023
PJM West Hub Day Ahead Peak - $/MWh	$	37.67	$	35.40
PJM PPL Zone Day Ahead Peak - $/MWh	28.34		25.97
PJM BGE Zone Day Ahead Peak - $/MWh	45.10		42.70
Texas Eastern M-3 - $/MMBtu	1.53		1.50

39

The PJM West Hub Day Ahead Peak 2024 quarter average settled prices increased approximately 6% compared to the prior year.

The weighted average forward market prices for the periods from July 1 through December 31 as of June 30:

	2024		2023
PJM West Hub ATC - $/MWh	$	43.64	$	37.48
Texas Eastern M-3 - $/MMBtu	2.14		2.19
PJM West Hub ATC Spark Spreads (a)	28.64		22.13

__________________

(a)Spark spreads are computed based on day-ahead West Hub ATC prices, TETCO M-3 gas prices, and a heat rate of 7 MMBtu/MWh.

Capacity Markets

Our generation capacity is located in markets with capacity products, which are intended to ensure long-term grid reliability for customers by securing sufficient power supply resources to meet predicted future demand. Capacity prices are affected by supply and demand fundamentals, such as generation facility additions and retirements, capacity imports from and exports to adjacent markets, generation facility retrofit costs, non-performance risk premium penalties, demand response products, ISO demand forecasts, reserve margin targets and adjustments to PJM MSOC as determined by the PJM IMM.

PJM Capacity Auctions. Under the RPM, PJM conducts a series of capacity auctions. Most capacity is procured in the auctions conducted each May for the delivery of generation capacity for the PJM Capacity Year, which is three years from the date of the auction. Capacity auctions have recently been delayed, resulting in the auctions being held with less than 3 years between the auctions and the PJM Capacity Year, with the most recent auction held in July 2024. The capacity market construct provides generation owners the opportunity for some revenue visibility on a multiyear basis. The results of each of these auctions impacts Talen's capacity revenues in the specific PJM Capacity Year.

See “Capacity Prices” below for additional information on capacity prices and see Note 10 in Notes to the Interim Financial Statements for additional information on the PJM RPM and other PJM matters.

Capacity Prices. The following table displays the PJM Base Residual Auction’s cleared capacity prices for the markets and zones in which we primarily operate:

	2025/2026 (b)		2024/2025		2023/2024		2022/2023
PJM Capacity Performance ($/MW-day) (a)
MAAC	$	269.92	$	49.49	$	49.49	$	95.79
PPL	269.92		49.49		49.49		95.79

Nuclear Production Tax Credit

The Inflation Reduction Act of 2022 was signed into law in August 2022. Among the Act’s provisions are amendments to the Internal Revenue Code of 1986 to create a Nuclear PTC program.

The Nuclear PTC program provides qualified nuclear power generation facilities with a $3 per MWh transferable credit for electricity produced and sold to an unrelated party during each tax year. Electricity produced and sold by Susquehanna after December 31, 2023 through December 31, 2032 will qualify for the credit, which is subject to potential adjustments. Such adjustments include inflation escalators, a five-times increase in tax credit value (to $15 per MWh) if the qualifying generation facility meets prevailing wage requirements, and a pro-rata decrease in tax credit value once the annual gross receipts of a qualifying generation facility exceeds $25 per MWh. As the credit is eliminated when the annual gross receipts are equivalent to $43.75 per MWh (adjusted for inflation), the Nuclear PTC program is expected to create a minimum price Susquehanna is expected to receive for its generation. Susquehanna generated approximately 18 million MWh in each of the calendar years 2023, 2022 and 2021.

The credit would be:

Annual Gross Receipts	Credit Amount
$25 per MWh or less	$15 per MWh
Greater than $25 per MWh	Ratably reduced until gross receipts equal $43.75 per MWh, $0 after that threshold

The Inflation Reduction Act’s provisions are subject to implementation regulations, whose terms are not yet known. No assurance can be provided as to the magnitude of the benefit to Susquehanna as the Inflation Reduction Act’s provisions, including the computations of the Nuclear PTC, are subject to implementation regulations. As such, Talen cannot fully predict the realization of any minimum price for Susquehanna’s generation and (or) impacts to Talen’s liquidity or results of operations. See Note 4 in Notes to the Interim Financial Statements for additional information on Nuclear PTC revenue recognized.

Seasonality/Scheduled Maintenance

The demand for and market prices of electricity and natural gas are affected by weather. As a result, our operating results in the future may fluctuate substantially on a seasonal basis. For example, a lack of sustained cold weather in the Mid-Atlantic region may suppress regional natural gas prices and reduce our future capacity and energy revenues. Alternatively, above-average temperatures in the summer tend to increase summer cooling electricity demand, energy prices and revenues, and below-average temperatures in the winter tend to increase winter heating electricity demand, energy prices and revenues. Inversely, the milder weather during spring and fall tend to decrease the need for both cooling electricity demand and heating electricity demand. In addition, our operating expenses typically fluctuate on a seasonal basis, with peak power generation during the winter in the Mid-Atlantic region.

We ordinarily perform facility maintenance during lower or non-peak demand periods to ensure reliability during periods of peak usage. The pattern of the fluctuations in our operating results varies depending on the type and location of the power generation facilities being serviced, capacity markets served, the maintenance requirements of our facilities and the terms of bilateral contracts to purchase or sell electricity. The largest recurring maintenance project is the annual spring refueling outage at Susquehanna. The outages normally occur during late March and into April each year. Susquehanna Unit 1 entered its spring refueling outage on March 25, 2024 and successfully completed the outage on April 25, 2024.

Results of Operations

The results of operations presented below should be reviewed in conjunction with the Interim Financial Statements, the Annual Financial Statements, and their respective notes. Our financial results for the three months ended June 30, 2024, the six months ended June 30, 2024, and for the period May 18 through June 30, 2023 are referred to as the “Successor” periods. Our financial results for the period April 1 through May 17, 2023 and for the period from January 1 through May 17, 2023 are referred to as the “Predecessor” periods. The operating results for the three and six months ended June 30, 2024 cannot be adequately compared with any of the previous periods reported in the Interim Financial Statements or Annual Financial Statements. Our results of operations as reported in the Interim Financial Statements are prepared in accordance with GAAP.

In the explanations below, “Energy and other revenues” and “Fuel and energy purchases” are evaluated collectively because the price for power is generally determined by the variable operating cost of the next marginal generator dispatched to meet demand. Energy revenues relate to sales to an ISO or RTO, sales under wholesale bilateral contracts or realized hedging activity, Bitcoin revenue and Nuclear PTC revenue. “Fuel and energy purchases” includes costs for fuel to generate electricity and settlements of financial and physical transactions related to fuel and energy purchases.

In addition, unrealized gains (losses) on derivatives instruments resulting from changes in fair value during the period and are presented separately as revenues within “Operating Revenues” and expenses within “Total Energy Expenses” in the Interim Financial Statements. We evaluate them collectively because they represent the changes in fair value of Talen’s economic hedging activities.

Liquidity and Capital Resources

Our liquidity and capital requirements are generally a function of: (i) debt service requirements; (ii) capital expenditures; (iii) maintenance activities; (iv) liquidity requirements for our commercial and hedging activities, including cash collateral and other forms of credit support; (v) legacy environmental obligations; and (vi) other working capital requirements.

Our primary sources of liquidity and capital include available cash deposits, cash flows from operations, amounts available under our debt facilities and potential incremental financing proceeds. Generating sufficient cash flows for our business is primarily dependent on capacity revenue, the production and sale of power at margins sufficient to cover fixed and variable expenses, hedging strategies to manage price risk exposure, and the ability to access a wide range of capital market financing options.

Our hedging strategy is focused on establishing appropriate risk tolerances with an emphasis on protecting cash flows across our generation fleet. Our strong balance sheet provides ample capacity and counterparty appetite for lien-based hedging, which does not require cash collateral posting. Specifically, our hedging strategy prioritizes a first lien-based hedging program in which hedging counterparties are granted a lien in the same collateral securing our first-lien debt obligations. This strategy limits the use of exchange-based hedging and the associated margin requirements, which helps minimize collateral posting requirements. Additionally, there are lower overall hedging needs given the cash-flow stability afforded by the Nuclear PTC and significantly reduced debt service requirements.

We are partially exposed to financial risks arising from natural business exposures including commodity price and interest rate volatility. Within the bounds of our risk management program and policies, we use a variety of derivative instruments to enhance the stability of future cash flows to maintain sufficient financial resources for working capital, debt service, capital expenditures, debt covenant compliance and (or) other needs.

In June 2024, using available cash deposits, the Company completed a tender offer which resulted in the purchase of 5,275,862 shares of its common stock for $612 million, exclusive of transaction costs.

In July 2024, the Company repurchased $2,413,793 shares from affiliates of Rubric Capital Management LP for an aggregate purchase price of $280 million. There were de minimis transaction costs associated with this repurchase.

See Notes 3, 9 and 16 in Notes to the Interim Financial Statements for additional information regarding various liquidity topics discussed below.

Talen Liquidity

	Successor
	June 30, 2024		December 31, 2023
Cash and cash equivalents, unrestricted	$	632	$	400
RCF	640		638
Available liquidity	$	1,272	$	1,038

Based on current and anticipated levels of operations, industry conditions and market environments in which we transact, we believe available liquidity from financing activities, cash on hand and cash flows from operations (including changes in working capital) will be adequate to meet working capital, debt service, capital expenditures and (or) other future requirements for the next twelve months and beyond.

Financial Performance Assurances

	Successor
	June 30, 2024		December 31, 2023
Outstanding surety bonds	$	235	$	240

TES has provided financial performance assurances in the form of surety bonds to third parties on behalf of certain subsidiaries for obligations including, but not limited to, environmental obligations and AROs. Surety bond providers generally have the right to request additional collateral to backstop surety bonds.

Forecasted Uses of Cash

See Management’s Discussion and Analysis of Financial Condition and Results of Operations in the Annual Financial Statements attached to the Registration Statement for information regarding forecasted uses of cash related to capital expenditures and forecasted spending on AROs and accrued environmental liabilities.

Indebtedness

Long-Term Debt Repricing. In May 2024, the Company completed a repricing of the TLB and TLC. The lenders agreed to, among other things lower the interest charges by 100 basis points and waive the prepayment obligation in connection with the ERCOT Sale.

Remarketing of PEDFA Bonds. In June 2024, the Company completed the remarketing of $50 million in aggregate principal amount of its PEDFA 2009B and $81 million in aggregate principal amount of its PEDFA 2009C Bonds. The bonds will bear interest at 5.25% until the end of the new term rate period on June 2027. In connection with the remarketing, $133 million of LCs issued under the TLC LCF that had previously supported the bonds were terminated, providing the Company with increased LC capacity under the TLC LCF.

See Note 11 in Notes to the Interim Financial Statements for additional information on the repricing and Talen’s indebtedness.

Contractual Obligations and Commitments

Guarantees of Subsidiary Obligations

TES guarantees certain agreements and obligations for its subsidiaries. Certain agreements may contingently require payments to a guaranteed or indemnified party. See Note 10 in Notes to the Interim Financial Statements for additional information regarding guarantees.

Non-GAAP Financial Measure

We include Adjusted EBITDA, which the Company uses as a measure of its performance and is not a financial measure prepared under GAAP, in these Interim Financial Statements. 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, non-GAAP financial measures are numerical measures of financial performance, financial position, or cash flows that exclude (or include) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP. Management cautions readers of this financial information not to place undue reliance on this non-GAAP financial measure, but to also consider them along with their most directly comparable GAAP financial measure. Non-GAAP measures have limitations as an analytical tool and should not be considered in isolation or as a substitute for analyzing our results as reported under GAAP.

52

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 the Company’s 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 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; 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. Pursuant to TES’s debt agreements, Cumulus Digital contributes to Adjusted EBITDA beginning in the first quarter 2024, following termination of the Cumulus Digital credit facility and associated cash flow sweep.

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 the 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.

Critical Accounting Policies and Estimates

The Company’s financial statements are prepared in conformity with GAAP, which require the application of appropriate accounting policies to form the basis of estimates utilizing methods, judgments, and (or) assumptions that materially affect: (i) the measurement and carrying values of assets and liabilities as of the date of the financial statements; (ii) the revenues recognized and expenses incurred during the presented reporting periods; and (iii) financial statement disclosures of commitments, contingencies, and other significant matters. Such judgments and assumptions may include significant subjectivity due to inherent uncertainties of future events which exist to such an extent that there is a reasonable likelihood that materially different amounts would have been reported under different conditions or if different assumptions had been used. See the Annual Financial Statements attached to the Registration Statement for a description of our critical accounting policies and estimates.
