Dynegy Announces 2017 Financial Results

Adjusted EBITDA totaled $818 million during 2017 compared to $757 million in 2016. The increase was primarily due to the contribution from the newly acquired ENGIE plants, higher capacity revenues, and lower O&M costs, partially offset by lower generation volumes due to milder weather.

NY/NE - The 2017 operating loss was $113 million compared to an operating loss of $29 million for 2016. Factors that led to the higher operating loss included a change in the mark-to-market value of derivative transactions and a loss on the sale of the Dighton and Milford facilities in Massachusetts, partially offset by higher capacity revenues, lower depreciation costs, and income from the newly acquired ENGIE plants.

Adjusted EBITDA totaled $293 million in 2017 compared to $171 million in 2016 primarily due to the contribution from the newly acquired ENGIE plants.

ERCOT - Dynegy's ERCOT segment was initiated in February 2017 with the acquisition of ENGIE plants in Texas. The 2017 operating loss of $147 million was primarily driven by mark-to-market losses on derivative transactions and depreciation expenses.

Adjusted EBITDA totaled $26 million, with energy margin, net of hedges, partially offset by O&M costs.

MISO - The 2017 operating loss was $44 million compared to an operating loss of $832 million in 2016. The previous year results were primarily driven by approximately $790 million in impairment charges.

Adjusted EBITDA totaled $152 million in 2017 compared to $129 million in 2016 due to higher capacity revenues that resulted from favorable pricing and volumes.

CAISO - The 2017 operating loss was $45 million compared to an operating loss of $5 million for 2016. The higher operating loss resulted from lower capacity revenues due to lower contracted volumes and prices and lower tolling revenue due to the expiration of a tolling contract, partially offset by higher energy margin, net of hedges, as a result of warmer weather.

Adjusted EBITDA totaled $19 million in 2017 compared to $59 million in 2016 as lower volumes and prices for capacity and the expiration of tolling agreements impacted results.

Fourth Quarter Comparative Results

Segment Review of Results Quarter-over-Quarter

PJM - Operating income for the fourth quarter 2017 totaled $14 million compared to $137 million for the fourth quarter 2016. The decrease was primarily due to a change in the mark-to-market value of derivative transactions.

Adjusted EBITDA totaled $216 million in 2017 versus $181 million in 2016 as the contribution from the newly acquired ENGIE plants and higher capacity revenues were partially offset by a lower retail contribution due to higher supply costs and milder weather.

NY/NE - The fourth quarter 2017 operating loss was $41 million compared to an operating loss of $7 million for the fourth quarter 2016. The decrease was primarily due to a change in the mark-to-market value of derivative transactions.

Adjusted EBITDA totaled $99 million in 2017 compared to $29 million in 2016. The increase was primarily due to the contribution from the newly acquired ENGIE plants, higher capacity revenues, and lower O&M expenses.

ERCOT- The fourth quarter 2017 operating loss of $139 million was primarily driven by mark-to-market losses on derivative transactions and depreciation expenses, which more than offset positive energy margin.

Adjusted EBITDA totaled $(12) million as a result of O&M expenses associated with plant outages, which more than offset positive energy margin.

MISO - Operating income for the fourth quarter 2017 totaled $6 million compared to an operating loss of $42 million for the fourth quarter 2016 as lower O&M and depreciation expenses benefited results.

Adjusted EBITDA remained unchanged at $28 million in 2017 and in 2016.

CAISO - The fourth quarter 2017 operating loss was $12 million compared to a $5 million operating loss for the fourth quarter 2016 as lower capacity and tolling revenue impacted results.

Adjusted EBITDA in 2017 was $5 million versus $14 million in 2016 primarily due to lower capacity and tolling revenue in the most recent period.

Liquidity

Dynegy’s total available liquidity is reflected in the table below.

________________________

(1) Includes $1.545 billion in senior secured revolving credit facilities and $105 million related to letter of credit facilities (“LCs”).

Consolidated Cash Flow

Cash provided by operations totaled $585 million for the full year of 2017. During the period, our power generation facilities and retail operations provided cash of $1.25 billion. Corporate activities, primarily related to general and administrative, interest, and acquisition-related expenses, as well as other working capital changes, used cash of $669 million during the period.

Cash used in investing activities totaled $2.76 billion for the full year of 2017 as Dynegy used $3.25 billion at the ENGIE acquisition closing, $70 million, including $20 million in working capital, for the purchase of interest in Miami Fort and Zimmer from AES, and invested $224 million in capital expenditures, offset by $773 million in proceeds received from asset sales, in addition to $12 million in distributions received from our unconsolidated investments in the Bellingham NEA and Sayreville facilities.

Cash used in financing activities totaled $1.3 billion for the full year of 2017 primarily as a result of the remaining payment obligations relating to the purchase of Energy Capital Partners' (ECP) interest in Atlas Power, payments related to our Illinois Power Generating Company subsidiary's (Genco) emergence from bankruptcy, and the repayment of the outstanding revolving credit facility, as well as various other financing activities.

Capital Structure

During 2017 numerous steps were taken to streamline and strengthen Dynegy’s capital structure including:

• Used asset sale proceeds, cash on hand, and proceeds from an $850 million bond offering to repay/refinance $1.75 billion in debt;
• Restructuring the Genco subsidiary, eliminated $825 million of Genco senior notes in exchange for approximately $122 million in cash, $188 million of seven-year unsecured notes, and 9 million Dynegy common stock warrants; and
• Added more flexibility and improved the terms of our Credit Agreement by executing amendments to increase its capacity, extend its maturity date, and reduce the interest rate margin by 125 basis points.

Commodity Pricing and Impact of Hedges

Throughout the fourth quarter of 2017, Dynegy continued to actively hedge its fleet for 2018 and 2019, taking advantage of a rise in forward commodity prices experienced in late 2017. In the fourth quarter of 2017, forward pricing for 2018 and 2019 improved in many of Dynegy’s key markets as both spark and dark spreads expanded. This improved outlook has resulted in an increase in forecasted run times as plants are now more deeply in the money. Gross margin is expected to increase as Dynegy's generation facilities are now projected to run more hours at higher prices.

As of February 8, 2018, Dynegy’s 2018 generation volumes hedged in the key markets of PJM, NY/NE, ERCOT, and MISO stood at 78%, 64%, 74%, and 75%, respectively. In 2019, hedging in the same markets is at 40%, 19%, 26%, and 39%, respectively.

As we move forward, we will continue to look for opportunities to hedge future generation at advantageous levels.

Recent Developments

Vistra Merger

On October 29, 2017, Dynegy and Vistra Energy Corp. entered into a Merger Agreement that has been approved by the boards of directors of both companies. Dynegy will merge with and into Vistra Energy in a tax-free, all-stock transaction.

We expect the transaction to close in the second quarter of 2018 after meeting the remaining customary conditions including stockholder approval and receiving the required regulatory approvals, including the Federal Energy Regulatory Commission, the Public Utility Commission of Texas, and the New York Public Service Commission.

Tax Reform Act

The Tax Cuts and Jobs Act (TCJA), enacted on December 22, 2017, reduces the U.S. federal corporate tax rate from 35% to 21%. This resulted in a reduction to our net deferred tax assets with a corresponding reduction to our valuation allowance. The TCJA also repealed the corporate Alternative Minimum Tax (AMT), which resulted in a $223 million tax benefit for Dynegy. As prescribed by the TCJA, and unless used to offset a cash tax liability, Dynegy will receive the cash refunds of our existing AMT credits beginning in 2019, for the 2018 tax year, through 2022. Estimated cash refunds by year: 2019 - $112 million; 2020 - $56 million; 2021 - $28 million; 2022 - $27 million.

ENGIE Acquisition

On February 7, 2017, Dynegy completed its acquisition of ENGIE’s US portfolio, which included more than 9,000 megawatts of generation facilities for a base purchase price of approximately $3.3 billion. The plants acquired included 15 natural gas-fueled facilities in Illinois, Massachusetts, New Jersey, Ohio, Pennsylvania, Texas, Virginia, and West Virginia, as well as one coal-fueled facility in Texas and a waste-coal-fueled facility in Pennsylvania.

Portfolio Changes

During 2017, Dynegy sold its Armstrong (Pennsylvania), Dighton (Massachusetts), Lee (Illinois), Milford (Massachusetts), and Troy (Ohio) facilities. In addition, Dynegy sold its 40 percent ownership interest in the Conesville facility in Ohio and, through separate transactions with AEP and AES, raised its ownership in the Miami Fort and Zimmer facilities in Ohio to 100%.

PRIDE Update and Earnings and Cost Improvement Project

Dynegy’s PRIDE (Producing Results through Innovation by Dynegy Employees) program was launched in 2011 with a focus on optimizing our cost structure, implementing company-wide process and operating improvements, and improving balance sheet efficiency. In 2017 the program exceeded its balance sheet target of $100 million by $41 million and its EBITDA target of $65 million by $24 million.

Dynegy introduced its Earnings and Cost Improvement (ECI) project in the fourth quarter 2017 to identify and implement practices that promote leading practices across key areas of our power generation fleet. The initiative is driven by employees with assistance from a third-party consultant. ECI's target is more than $100 million in sustainable earnings improvements.

Retail Business Expansion

The retail business continued its effort to expand into new markets during 2017 by serving new municipal aggregation customers in Massachusetts and through commercial and industrial sales in the Pennsylvania market for 2018 delivery. Retail now serves customers in Illinois, Massachusetts, Ohio, and Pennsylvania. Retail delivered volumes in 2017 were 26,000 gigawatt-hours to its approximately 1.2 million residential and business customers.

Safety

Dynegy's safety performance for the full-year 2017 was in the top decile for the industry. Both coal and gas facilities are focused on intensive safety initiatives that help drive safety culture. A total of seven Dynegy plants have achieved STAR Program status through the Occupational Safety and Health Administration’s Voluntary Protection Program (VPP). Dynegy is committed to having all of its plants go through the VPP auditing process in the next several years.

About Dynegy

Throughout the Northeast, Mid-Atlantic, Midwest, Texas and California, Dynegy operates nearly 28,000 megawatts (MW) of power generating facilities capable of producing enough energy to supply more than 23 million American homes. Through our retail business, we serve 1.2 million customers who depend on reliable, affordable energy to grow and thrive.
