Talen Energy (TLN) S-8Registration of securities for employees

Talen Energy Corporation (the “Registrant”) will provide to all participants in the Talen Energy Corporation 2023 Equity Incentive Plan (the “Plan”) with the document(s) containing the information required by Part I of Form S-8, as specified in Rule 428(b)(1) promulgated by the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”). In accordance with Rule 428 under the Securities Act, the Registrant has not filed such document(s) either as part of this Registration Statement or as a prospectus or prospectus supplement pursuant to Rule 424 under the Securities Act. These documents and the documents incorporated by reference in this Registration Statement pursuant to Item 3 of Part II of Form S-8, taken together, constitute a prospectus that meets the requirements of Section 10(a) of the Securities Act. The Registrant shall maintain a file of such documents in accordance with the provisions of Rule 428(a)(2) under the Securities Act. Upon request, the Registrant shall furnish to the Commission or its staff a copy or copies of all of the documents included in such file.

Except to the extent that information is deemed furnished and not filed pursuant to securities laws and regulations, the following documents have been filed by the Registrant with the Commission and are incorporated by reference into this Registration Statement on Form S-8 (the “Registration Statement”) and will be deemed to be a part hereof:

Except to the extent that information is deemed furnished and not filed pursuant to securities laws and regulations, all documents filed by the Registrant pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date hereof and prior to the filing of a post-effective amendment that indicates that all securities offered have been sold or that deregisters all securities then remaining unsold shall also be deemed to be incorporated by reference herein and to be a part hereof from the dates of filing of such documents. Any statement contained in a document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Section 145 of the Delaware General Corporation Law (“DGCL”) authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities, including reimbursement for expenses incurred, arising under the Securities Act. Our Third Amended and Restated Certificate of Incorporation (“Charter”) permits indemnification of our directors and officers to the maximum extent permitted by the DGCL, and our Second Amended and Restated Bylaws (“Bylaws”) provide that we will indemnify our directors and officers and permit us to indemnify our employees and other agents, in each case to the maximum extent permitted by the DGCL.

We have entered into indemnification agreements with our directors and officers, whereby we have agreed to indemnify our directors and officers to the fullest extent permitted by law, including indemnification against expenses and liabilities incurred in legal proceedings to which the director or officer was, or is threatened to be made, a party by reason of the fact that such director or officer is or was a director or officer of ours, provided that such director or officer acted in good faith, in a manner that the director or officer reasonably believed to be in, or not opposed to, our best interest, and with respect to any criminal proceeding, had no reasonable cause to believe their conduct was unlawful.

The indemnification provisions in our Charter, Bylaws and the indemnification agreements that we have entered into, or will enter into, with our directors and executive officers may discourage stockholders from bringing a lawsuit against our directors and executive officers for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against our directors and executive officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and executive officers as required by these indemnification provisions. At present, there is no pending litigation or proceeding involving a director or officer of ours regarding which indemnification is sought, nor is the Registrant aware of any threatened litigation that may result in claims for indemnification.

We maintain insurance policies that indemnify our directors and officers against various liabilities arising under the Securities Act and the Exchange Act that might be incurred by any director or officer in his or her capacity as such.

Certain of our non-employee directors may, through their relationships with their employers, be insured and/or indemnified against certain liabilities incurred in their capacity as members of our board of directors.

The Plan also provides that the committee administering the Plan (the “Committee”) is entitled to rely upon any opinion and/or computation furnished to them by the Registrant’s legal counsel, consultants or agents assisting in the administration of the Plan. The Committee, its members, and any person designated or granted authority pursuant to the Plan shall not be liable for any action or determination made in good faith with respect to the Plan. To the fullest extent permitted by law, no officer or employee of the Registrant or the Registrant’s affiliates or member or former member of the Committee or of the board of directors of the Registrant shall be liable for any action or determination made in good faith with respect to the Plan or any award granted under it.

The above discussion of the DGCL, the Registrant’s Charter, Bylaws, indemnification agreements, the Plan, and the Registrant’s maintenance of directors’ and officers’ liability insurance is not intended to be exhaustive and is qualified in its entirety by reference to such statute or applicable document.

Not applicable.
