Item 8.01. Other Events.

Dynegy Inc. (the “Company”) is filing this Current Report on Form 8-K to update the presentation of certain financial information and related disclosures contained in its Form 10-K for the year ended December 31, 2016 (the “2016 Form 10-K”) which was filed with the Securities and Exchange Commission (“SEC”) on February 24, 2017.

In accordance with the registration statement requirements of the SEC, the Company is required to revise previously issued financial statements when the adoption of a new accounting standard requires a retrospective application that materially revises those financial statements, if those financial statements are included, or are or will be incorporated by reference in certain subsequent filings with the SEC.

This Form 8-K retrospectively revises our financial statements as of December 31, 2016, and for all periods presented, to reflect the adoption of Accounting Standards Update (“ASU”) 2016-15-Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments and ASU 2016-18-Statement of Cash Flows (Topic 230): Restricted Cash. This update is consistent with the presentation in the Company’s Form 10-Q’s for the quarters ended March 31, 2017, June 30, 2017, and September 30, 2017 filed with the SEC on May 5, 2017, August 4, 2017, and November 1, 2017 respectively. The retrospectively revised Items contained in the Company’s 2016 Form 10-K are presented in Exhibits 99.1, 99.2 and 99.3 to this Form 8-K.

The exhibits to this Current Report on Form 8-K supersede the following Items in the 2016 Form 10-K to reflect, retrospectively, the changes resulting from the adoption of the ASUs referenced above:

· Part II, Item 6. Selected Financial Data

· Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”)

· Part II, Item 8. Financial Statements and Supplementary Data

All other information in the 2016 Form 10-K remains unchanged. Unaffected portions of the 2016 Form 10-K have not been repeated in, and are not amended or modified by, this Current Report on Form 8-K or Exhibits 99.1, 99.2 and 99.3 to this Form 8-K. This Current Report on Form 8-K does not reflect events occurring subsequent to the filing of the 2016 Form 10-K and does not modify or update the disclosures therein in any way, other than as required to reflect the reclassifications as described above and as set forth in the exhibits attached hereto. Without limitation to the foregoing, this Current Report on Form 8-K does not purport to update the MD&A in the 2016 Form 10-K for any information, uncertainties, risks, events or trends occurring or known to management. For developments since the filing of the 2016 Form 10-K, please refer to the First, Second, and Third Quarter 2017 Form 10-Q’s, as well as other filings of the Company made with the SEC. The information in this Current Report on Form 8-K should be read in conjunction with the 2016 Form 10-K and such subsequent filings.
