HOUSTON (February 23, 2017) - Dynegy Inc. (NYSE: DYN) reported a net loss for 2016 of $1.24 billion, compared to net income of $50 million for 2015. The year-over-year decrease was primarily driven by asset impairments related to the Baldwin, Newton and Stuart plants in 2016 and a second quarter 2015 deferred tax valuation allowance reversal which benefited 2015, but did not reoccur in 2016. This decrease was partially offset by the first quarter 2016 contribution from the Duke and EquiPower plants acquired in April 2015.

The Company reported 2016 consolidated Adjusted EBITDA of $1,007 million, compared to $850 million for 2015. The $157 million increase was primarily due to full-year contributions from the Duke and EquiPower plants in 2016 versus nine months in 2015. Partially offsetting this benefit were lower energy margins, net of hedges, across the majority of the segments primarily due to mild temperatures in the first quarter 2016 and lower capacity revenues at the PJM and NY/NE segments as a result of lower capacity prices.

The Company reported a fourth quarter 2016 net loss of $180 million, compared to a net loss of $134 million for 2015. The quarter-over-quarter change was primarily driven by Genco reorganization items, primarily due to the write-off of the remaining unamortized discount related to the Genco bonds.

The Company reported fourth quarter 2016 consolidated Adjusted EBITDA of $219 million, compared to $222 million for the fourth quarter 2015 as improved energy margins, net of hedges, and lower O&M costs at the PJM and MISO segments were offset by lower energy and capacity revenues in the NY/NE and PJM segments.

“The ENGIE acquisition solidified the transformation of our wholesale generation business we began in 2013. We have built the most efficient and lowest-cost platform in the industry while migrating our portfolio to a gas-dominated fleet in the ERCOT, NE-ISO and PJM markets. Our portfolio today has the longevity required for success,” said Dynegy President and Chief Executive Officer Robert C. Flexon.

“Looking ahead to 2017, our efforts are aimed at optimizing our portfolio in conjunction with improving our balance sheet and capital structure and today’s announcement with LS Power is a step in that direction,” Flexon continued. “In keeping with our integration track record, we now expect to deliver $120 million in synergies related to the ENGIE acquisition, a step up from our initial $90 million estimate.”

Segment Review of Results Year-over-Year

PJM - The 2016 operating income was $414 million, compared to $423 million for 2015. The change was due to lower capacity revenues, non-cash mark-to-market losses on derivatives, higher O&M costs and 2016 impairment charges. Partially offsetting this was the full-year contribution of the Duke and EquiPower plants acquired in April 2015.

Adjusted EBITDA totaled $757 million during 2016 compared to $649 million in 2015, primarily due to the positive impact of the Duke and EquiPower plants which was partially offset by lower capacity prices and higher planned outage O&M costs.

NY/NE - The 2016 operating loss was $29 million, compared to $56 million for 2015. The change was attributable to a full-year 2016 contribution from the EquiPower plants versus nine months of 2015, lower impairment charges, lower depreciation due to a 2015 impairment and non-cash mark-to-market gains on derivatives. Adjusted EBITDA totaled $171 million in 2016 compared to $175 million in 2015.

MISO - The 2016 operating loss was $745 million, compared to a loss of $92 million in 2015, due to higher impairment charges. Adjusted EBITDA totaled $27 million for both 2016 and 2015.

IPH - The 2016 operating loss was $87 million, compared to 2015 operating income of $49 million as higher capacity revenues and lower O&M costs were offset by higher 2016 impairment charges. Adjusted EBITDA totaled $102 million in 2016, compared to $77 million in 2015 due to higher capacity revenues and lower O&M costs from fewer planned outages.

CAISO - The 2016 operating loss was $5 million, compared to $8 million for 2015 as a result of lower energy margin, net of hedges. Adjusted EBITDA totaled $59 million in 2016 compared to $44 million in 2015, primarily due to higher capacity revenues and a supplier settlement.

Segment Review of Results Quarter-over-Quarter

PJM - The fourth quarter 2016 operating income was $137 million, compared to $101 million for the fourth quarter 2015. The increase was due to higher energy margin, net of hedges, and non-cash mark-to-market gains on derivatives, partially offset by lower capacity revenues. Adjusted EBITDA totaled $181 million in 2016 versus $171 million in 2015 as lower O&M and higher retail margins benefited results.

NY/NE - The fourth quarter 2016 operating loss was $7 million, compared to $55 million for the fourth quarter 2015 due to lower impairment charges and non-cash mark-to-market gains on derivatives, partially offset by lower energy margin, net of hedges. Adjusted EBITDA totaled $29 million in 2016 compared to $56 million in 2015 primarily due to lower energy margins, net of hedges.

MISO - The fourth quarter 2016 operating loss was $42 million, compared to $28 million for the fourth quarter 2015. The decrease was due to lower energy margin, net of hedges, and non-cash mark-to-market losses on derivatives. Adjusted EBITDA increased to $8 million in 2016 compared to ($1) million in 2015 primarily due to lower O&M expense from fewer planned outages.

IPH - The fourth quarter 2016 operating income was zero, compared to $10 million for the fourth quarter 2015 primarily due to higher O&M costs. Adjusted EBITDA was $20 million in 2016 and $16 million in 2015.

CAISO - The fourth quarter 2016 operating loss was $5 million, compared to $6 million for the fourth quarter 2015. Adjusted EBITDA in 2016 was $14 million versus $12 million in 2015 primarily due to higher capacity revenues in the most recent period.

Total available liquidity	$	2,815		$	103		$	2,918		$	1,460

(1) Includes Cash and cash equivalents of $64 million related to Genco, which was operating as debtor-in-possession in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

(2) The seller in the ENGIE acquisition provides certain transition credit support through February 7, 2019, and we will use the LC availability as this support terminates.

(3) Dynegy Inc. includes $1.425 billion in senior secured revolving credit facilities and $55 million related to an LC. IPH consists of $44 million related to IPM LCs. The IPM LCs are collateralized by cash, and as of December 31, 2016, IPM had $19 million deposited with the issuing banks.

Consolidated Cash Flow

Cash provided by operations for the full year of 2016 was $676 million. During the full year 2016, our power generation facilities and retail operations provided cash of $1.02 billion. Corporate and other activities used cash of $557 million primarily for interest payments on various debt agreements of $538 million and acquisition-related costs of $19 million. In addition, changes in working capital and other provided cash of $216 million during the period.

Cash used in investing activities totaled $2.15 billion for the full year of 2016. During the period, restricted cash increased by $2.0 billion from proceeds from the tranche C term loan being held in escrow for the ENGIE acquisition and $21 million related to the original issuance discount and interest income. Additionally, we paid $326 million in capital expenditures, received $176 million from asset sales, received $14 million in distributions from our unconsolidated investment in Elwood and received $10 million in proceeds from an insurance claim.

Cash provided by financing activities totaled $2.74 billion for the full year of 2016 primarily due to $2 billion in proceeds related to the tranche C term loan, $750 million in proceeds from our 2025 bonds, $443 million in net proceeds from our tangible equity units and $198 million of proceeds related to our forward capacity agreement. This was partially offset by $18 million in financing costs related to our debt issuances, $550 million in voluntary repayments associated with our tranche B-2 term loan, $39 million in other scheduled debt payments, $22 million in dividend payments on our preferred stock and $17 million in interest rate swap settlement payments.

Recent Developments

Portfolio Changes

Dynegy has reached an agreement to sell two peaking facilities in PJM to LS Power for $480 million in cash. The assets to be sold include the Armstrong and Troy facilities totaling 1,269 MW. Proceeds will be used for debt reduction.

Dynegy reached an agreement with AEP to realign and consolidate the ownership of the Conesville and Zimmer Power Stations in Ohio. Dynegy agreed to sell its 40% ownership interest (312 MW) in Conesville Power Station and acquire AEP’s 25.4% ownership interest in Zimmer. No additional consideration will be paid to either party, however AEP will return a $58 million letter of credit previously posted by Dynegy to AEP. As a result, Dynegy will own 71.9% (971 MW) of the Company-operated Zimmer Power Station, a reliable and fully controlled coal plant and will no longer have an ownership interest in Conesville. The overall capacity for the Conesville and Zimmer generating stations is 780 MW and 1,350 MW, respectively.

Our co-owner of Killen Station, AES, is involved in an Electric Security Plan proceeding in Ohio in which AES has reached a settlement that, if approved, includes a plan to retire the Killen Station. Dynegy has agreed with AES to retire that plant by mid-2018. The Stuart Power Station, jointly owned by Dynegy, AES, and AEP, is also under advanced review for potential retirement. If both retirements occur, 2,900 MW of baseload coal generation would leave PJM. Dynegy continues to look to optimize its ownership structure in jointly owned units, Miami Fort and Zimmer Power Stations.

Genco Restructuring

Genco emerged from its prepackaged Chapter 11 restructuring on February 2, 2017. As a result, Genco’s $825 million in unsecured bonds were eliminated. Participating bondholders exchanged $757 million in bonds thus far for $113 million in cash, $182 million in new Dynegy unsecured bonds due 2024 and 8.7 million seven-year warrants for Dynegy Inc. common stock with a strike price of $35. Bondholders who did not participate have 165 days post-emergence to file a claim and receive consideration, after which time their claim will be permanently extinguished. As a result of the restructuring, Dynegy’s annual consolidated interest expense has been reduced by approximately $45 million. At year end, IPH had $84 million in cash on hand and $79 million in cash collateral posted, providing Dynegy with more than sufficient funding to pay bondholders. Upon return of all previously posted cash collateral and payment of advisor fees, approximately $38 million of cash will be retained by Dynegy.

ENGIE

On February 7, Dynegy completed its acquisition of ENGIE’s US portfolio. Dynegy repriced its term loan C resulting in approximately $100 million in interest savings over the next seven years. The Company also upsized the loan by $224 million to refinance the existing term loan B due in 2020, extending the maturity by four years to 2024. Simultaneous with closing, Dynegy upsized its liquidity facilities by $170 million to $1.65 billion and extended the maturity date on $450 million in existing revolver capacity from 2018 to 2021.

Separately, Dynegy has increased ENGIE synergy targets from $90 million to $120 million with 75% of the synergies secured at closing and a full 90% to be achieved by year end 2017.

PRIDE

PRIDE Energized (Producing Results through Innovation by Dynegy Employees) launched in early 2016 with goals of $250 million in EBITDA contributions and $400 million in balance sheet improvements by the end of 2018. Through the end of 2016, Dynegy achieved $150 million in contributions to EBITDA and $422 million in balance sheet improvements, reaching all balance sheet goals two years ahead of schedule.

(1) EBITDA and Adjusted EBITDA are non-GAAP financial measures. Please refer to Item 2.02 of our Form 8-K filed on February 23, 2017, for definitions, utility and uses of such non-GAAP financial measures. A reconciliation of EBITDA to Operating income (loss) is presented above. Management does not allocate G&A, interest expense and income taxes on a segment level and therefore uses Operating income (loss) as the most directly comparable GAAP measure.
