(HOUSTON, Texas) February 25, 2020 – Calpine Corporation today reported Net Income¹ of $770 million for the year ended December 31, 2019, compared to Net Income of $10 million in the prior year. The year-over-year increase in Net Income was primarily due to an increase in Commodity Margin² in our Texas and West segments and an increase in non-cash, mark-to-market earnings on our commodity hedge position for the year ended December 31, 2019 compared to 2018. Cash provided by operating activities for 2019 was $1,556 million compared to $1,101 million in the prior year. The increase in Cash provided by operating activities was primarily due to an increase in Commodity Margin,² as previously discussed, as well as a decrease in working capital employed resulting from a year-over-year net decrease in energy margin posting requirements and a change in environmental products balances.

REGIONAL SEGMENT REVIEW OF RESULTS

Table 1: Commodity Margin by Segment (in millions)

	Year Ended December 31,
	2019		2018		Variance
West	$	1,151	$	1,060	$	91
Texas	857		646		211
East	924		970		(46		)
Retail	382		357		25
Total	$	3,314	$	3,033	$	281

West

Commodity Margin in our West segment increased by $91 million in 2019 compared to the prior year. Primary drivers were:

+ higher resource adequacy revenues and

+ higher contribution from hedging activities, partially offset by

– lower revenue from reliability must run contracts and

– lower generation at our Geysers Assets resulting from a third-party transmission outage associated with a wildfire.

Texas

Commodity Margin in our Texas segment increased by $211 million in 2019 compared to the prior year. Primary drivers were:

+ higher market spark spreads during August and September 2019, partially offset by

– higher revenue in the first quarter of 2018 associated with the sale of environmental credits with no similar activity in the current year.

East

Commodity Margin in our East segment decreased by $46 million in 2019 compared to the prior year. Primary drivers were:

– lower regulatory capacity revenue in PJM and ISO-NE,

– the sale of our Garrison and RockGen Energy Centers on July 10, 2019, and

– a gain associated with the cancellation of a PPA recorded during the first quarter of 2018 with no similar activity in 2019, partially offset by

+ higher contribution from hedging activities, and

+ the commencement of commercial operations at our York 2 Energy Center in March 2019.

Retail

Commodity Margin in our Retail segment increased by $25 million in 2019 compared to the prior year. Primary drivers were:

+ increased contribution from gas supply hedging activity associated with our retail gas business and

+ lower costs.

____________

(1) Our ability to use corporate cash and cash equivalents is unrestricted. On January 21, 2020, we used the remaining cash on hand from the issuance of our 2028 First Lien Notes and 2028 Senior Unsecured Notes to redeem the remaining approximately $1,052 million aggregate principal amount of our 2022 and 2024 First Lien Notes and 2023 Senior Unsecured Notes.

(2) Our ability to use availability under our Corporate Revolving Facility is unrestricted. On April 5, 2019, we amended our Corporate Revolving Facility to increase the capacity by approximately $330 million from $1.69 billion to approximately $2.02 billion. On August 12, 2019, we amended our Corporate Revolving Facility to extend the maturity of $150 million in revolving commitments from June 27, 2020 to March 8, 2023, and to reduce the commitments outstanding by $20 million to approximately $2.0 billion. The entire Corporate Revolving Facility matures on March 8, 2023.

(3) Our CDHI revolving facility is restricted to support certain obligations under PPAs and power transmission and natural gas transportation agreements as well as fund the construction of our Washington Parish Energy Center. Pursuant to the terms and conditions of the CDHI credit agreement, the capacity under the CDHI revolving facility was reduced to $125 million on June 28, 2019. The decrease in capacity did not have a material effect on our liquidity as alternative sources of liquidity are available to us.

(4) We have three unsecured letter of credit facilities with two third-party financial institutions totaling approximately $300 million at December 31, 2019.

(5) Includes $127 million and $52 million of margin deposits posted with us by our counterparties at December 31, 2019 and 2018, respectively.

Liquidity was approximately $2.9 billion as of December 31, 2019. Cash, cash equivalents and restricted cash increased by $1.1 billion for the year ended December 31, 2019, largely due to cash provided by operating activities and proceeds from the issuance of our 2028 First Lien Notes and 2028 Senior Unsecured Notes in December 2019. These proceeds were utilized to redeem the remaining $1.1 billion aggregate principal amount of our 2022 and 2024 First Lien Notes and our 2023 Senior Unsecured Notes on January 21, 2020, as further discussed below. This increase was partially offset by distribution payments made to our parent, CPN Management, LP, in 2019, without comparable distributions in the prior year, as well as by increased capital expenditures on construction and growth projects.

Table 3: Cash Flow Activities (in millions)

	Year Ended December 31,
	2019			2018
Beginning cash, cash equivalents and restricted cash	$	406		$	443
Net cash provided by (used in):
Operating activities	1,556			1,101

Net increase (decrease) in cash, cash equivalents and restricted cash	1,070			(37		)
Ending cash, cash equivalents and restricted cash	$	1,476		$	406

Cash provided by operating activities in 2019 was $1,556 million compared to $1,101 million in the previous year. The year-over-year increase was primarily due to higher income from operations, adjusted for non-cash items, that resulted largely from an increase in Commodity Margin, as previously discussed, and a decrease in working capital employed resulting from a year-over-year net decrease in energy margin posting requirements and a change in environmental products balances.

Cash used in investing activities was $258 million during 2019 compared to $392 million in the prior year. The decrease primarily related to the receipt of proceeds from the sale of our Garrison and RockGen Energy Centers during the third quarter of 2019, partially offset by an increase in capital expenditures associated with construction and growth projects in the year ended December 31, 2019, compared to 2018.

Cash used in financing activities was $228 million during 2019 compared to $746 million in the prior year. The decrease was primarily related to net debt refinancing activity in the year ended December 31, 2019, compared to 2018 partially offset by distribution payments made to our parent, CPN Management, LP, in 2019, without comparable distributions in the prior year.

Portfolio Management

On March 17, 2019, our York 2 Energy Center commenced commercial operations, bringing online approximately 828 MW of combined cycle, natural gas-fired capacity with dual-fuel capability.

On July 10, 2019, we, through our indirect, wholly owned subsidiaries Calpine Holdings, LLC and Calpine Northbrook Project Holdings, LLC, completed the sale of 100% of our ownership interests in Garrison Energy Center LLC (“Garrison”) and RockGen Energy LLC (“RockGen”) to Cobalt Power, L.L.C. for approximately $360 million, subject to certain immaterial working capital adjustments and the execution of financial commodity contracts. Upon closing, we recognized a liability of $52 million for the fair value of the financial commodity contracts on our Consolidated Balance Sheet, and the related proceeds are reflected within the financing section on our Consolidated Statement of Cash Flows. Garrison owns the Garrison Energy Center, a 309 MW natural gas-fired, combined-cycle power plant located in Dover, Delaware, and RockGen owns the RockGen Energy Center, a 503 MW natural gas-fired, simple-cycle power plant located in Christiana, Wisconsin. We recorded an immaterial gain on the sale during the third quarter of 2019 and an impairment loss of $55 million for the year ended December 31, 2019, to adjust the carrying value of the assets to reflect fair value less cost to sell.

On November 20, 2019, we sold our 50% interest in Whitby Cogeneration (comprising 25 MW) to a third party and recorded a gain on sale of assets, net of approximately $5 million.

On January 28, 2020, we completed the acquisition of the 25% noncontrolling interest of Russell City Energy Company, LLC, from a third party for approximately $49 million. Subsequent to the acquisition, we will reflect 100% of the results of our 619 MW Russell City Energy Center in our earnings.

Capital Allocation

On July 18, 2019, our board of directors approved a special cash dividend of $400 million paid to our parent, CPN Management, LP, which was funded with the proceeds from the sale of the Garrison and RockGen Energy Centers, along with cash on hand. On November 20, 2019, we funded an additional cash dividend of $750 million to our parent, CPN Management, LP.

Balance Sheet Management

During the fourth quarter of 2019, we repurchased $112 million in aggregate principal amount of our Senior Unsecured Notes for $114 million. Since the fourth quarter of 2018, we have cumulatively repurchased $550 million in aggregate principal amount of our Senior Unsecured Notes for $513 million.

On December 27, 2019, we issued $1.4 billion in aggregate principal amount of 5.125% senior unsecured notes due 2028 in a private placement. Our 2028 Senior Unsecured Notes bear interest at 5.125% per annum, with interest payable semi-annually on March 15 and September 15 of each year, beginning on September 15, 2020. The 2028 Senior Unsecured Notes were issued at par, mature on March 15, 2028, and contain substantially similar covenants, qualifications, exceptions and limitations as our 2023 Senior Unsecured Notes, 2024 Senior Unsecured Notes and 2025 Senior Unsecured Notes. We recorded approximately $13 million in debt issuance costs during the fourth quarter of 2019 related to the issuance of our 2028 Senior Unsecured Notes. On December 27, 2019, we used the

Page 5

proceeds from the issuance of our 2028 Senior Unsecured Notes to redeem approximately $613 million of aggregate principal amount of our 2023 Senior Unsecured Notes, plus accrued and unpaid interest. In connection with the redemption during the fourth quarter of 2019, we recorded approximately $24 million in loss on extinguishment of debt, which includes approximately $18 million of prepayment premiums and approximately $6 million associated with the write-off of unamortized debt issuance costs. Additionally, on January 21, 2020, we redeemed the remaining $623 million in aggregate principal amount of our 2023 Senior Unsecured Notes, using the proceeds from the issuance of our 2028 Senior Unsecured Notes, which were included in cash and cash equivalents on our Consolidated Balance Sheet at December 31, 2019.

On December 20, 2019, we issued $1.25 billion in aggregate principal amount of 4.50% senior secured notes due 2028 in a private placement. Our 2028 First Lien Notes bear interest at 4.50% payable semi-annually on February 15 and August 15 of each year, beginning on August 15, 2020. Our 2028 First Lien Notes mature on February 15, 2028 and contain substantially similar covenants, qualifications, exceptions and limitations as our First Lien Notes. We recorded approximately $16 million in debt issuance costs during the fourth quarter of 2019 related to the issuance of our 2028 First Lien Notes. On December 20, 2019, we used the proceeds from the issuance of our 2028 First Lien Notes to redeem approximately $505 million and $306 million of aggregate principal amount of our 2022 First Lien Notes and 2024 First Lien Notes, respectively, plus accrued and unpaid interest. In connection with the redemption during the fourth quarter of 2019, we recorded approximately $20 million in loss on extinguishment of debt, including approximately $12 million of prepayment premiums and approximately $8 million associated with the write-off of unamortized discount and debt issuance costs. Additionally, on January 21, 2020, we redeemed the remaining $245 million and $184 million in aggregate principal amount of our 2022 First Lien Notes and 2024 First Lien Notes, respectively, using the proceeds from the issuance of our 2028 First Lien Notes, which were included in cash and cash equivalents on our Consolidated Balance Sheet at December 31, 2019.

PG&E Bankruptcy

On January 29, 2019, PG&E and PG&E Corporation each filed voluntary petitions for relief under Chapter 11. We currently have several power plants that provide energy and energy-related products to PG&E under PPAs, many of which have PG&E collateral posting requirements. Since the bankruptcy filing, we have received all material payments under the PPAs, either directly or through the application of collateral. We also currently have numerous other agreements with PG&E related to the operation of our power plants in Northern California, under which PG&E has continued to provide service since its bankruptcy filing. We cannot predict the ultimate outcome of this matter and continue to monitor the bankruptcy proceedings.

REGULATION G RECONCILIATIONS

In addition to disclosing financial results in accordance with U.S. GAAP, the accompanying earnings release contains non-GAAP financial measures. Commodity Margin, Adjusted Free Cash Flow and Adjusted Unlevered Free Cash Flow are non-GAAP financial measures that we use as measures of our performance and liquidity. These non-GAAP measures should be viewed as a supplement to and not a substitute for our U.S. GAAP measures of performance and liquidity, and the financial results calculated in accordance with U.S. GAAP and reconciliations from these results should be carefully evaluated.

Commodity Margin includes revenues recognized on our wholesale and retail power sales activity, electric capacity sales, renewable energy credit sales, steam sales, realized settlements associated with our marketing, hedging, optimization and trading activity less costs from our fuel and purchased energy expenses, commodity transmission and transportation expenses, environmental compliance expenses and ancillary retail expense. We believe that Commodity Margin is a useful tool for assessing the performance of our core operations and is a key operational measure of profit reviewed by our chief operating decision maker. Commodity Margin is not a measure calculated in accordance with U.S. GAAP and should be viewed as a supplement to and not a substitute for our results of operations presented in accordance with U.S. GAAP. Commodity Margin does not intend to represent income (loss) from operations, the most comparable U.S. GAAP measure, as an indicator of operating performance and is not necessarily comparable to similarly titled measures reported by other companies.

Adjusted Free Cash Flow represents cash flows from operating activities including the effects of capitalized maintenance expenditures, adjustments to reflect the Adjusted Free Cash Flow from unconsolidated investments and to exclude the noncontrolling interest and other miscellaneous adjustments such as the effect of changes in working capital. Adjusted Unlevered Free Cash Flow is calculated on the same basis as Adjusted Free Cash Flow but excludes the effect of cash interest, net, and operating lease payments, thus capturing the performance of our business independent of its capital structure. Adjusted Free Cash Flow and Adjusted Unlevered Free Cash Flow are presented because we believe they are useful measures of liquidity to assist in comparing financial results from period to period on a consistent basis and to readily view operating trends, as measures for planning and forecasting overall expectations and for evaluating actual results against such expectations and in communications with our board of directors, owners, creditors, analysts and investors concerning our financial results. Adjusted Free Cash Flow and Adjusted Unlevered Free Cash Flow are liquidity measures and are not intended to represent cash flows from operations, the most directly comparable U.S. GAAP measure, and are not necessarily comparable to similarly titled measures reported by other companies.
