Operating margin was approximately 13.3%, compared with 16.9% in 2019. Adjusted EBITDA margin was approximately 32.2%, versus 28.2%. These percentages are calculated from reported figures. Cash from operations less reported capital expenditures was approximately $2.078 billion; this is a simple calculation, not company-reported free cash flow. Interest expense and related charges were $630 million, down from $797 million. The 2020 effective tax rate was 29.9%.
At year-end, current assets were $3.429 billion and current liabilities were $3.036 billion. Long-term debt, including current maturities, was $9.330 billion; the balance sheet also included $300 million outstanding under the receivables securitization program. Total equity was $8.361 billion. Asset retirement obligations totaled $2.436 billion.
Material changes versus 2019
- Revenue declined $366 million and GAAP net income fell $302 million. Management attributed the net income decline in part to a $465 million unfavorable year-over-year change in unrealized commodity-hedge gains, $356 million of long-lived asset impairments, and a $29 million loss on disposal of the NELP investment.
- Adjusted EBITDA increased $360 million, or approximately 11%, and operating cash flow rose $601 million. Management cited strong Retail and Texas performance, including the benefit of hedging and plant optimization.
- Retail revenue increased to $8.270 billion from $6.872 billion, reflecting the inclusion of Crius and Ambit for more of the year. Retail electricity sales volumes rose to 90,349 GWh from 77,600 GWh.
- Operating costs and SG&A increased by $92 million and $131 million, respectively. The filing cites higher estimated asset-retirement costs, long-term service agreement costs, COVID-related costs, and acquired-business expenses.
- Interest expense declined by $167 million, mainly reflecting reductions in higher-interest parent-level notes and lower unrealized interest-rate-swap losses. Vistra redeemed its remaining parent-level senior notes during 2020.
- Capital expenditures increased to $1.259 billion, including $401 million of growth and development spending. Available liquidity increased by $673 million.
Outlook, commentary, risks and unusual items
- Winter Storm Uri, subsequent event: The February 2021 storm occurred after the reporting year. Vistra preliminarily estimated a one-time adverse pre-tax income impact of $900 million to $1.3 billion, largely from constrained generation and purchases of power at or near ERCOT’s price cap. Final settlement data, potential litigation and possible regulatory or market resettlements could change the estimate. The company reported more than $1.5 billion of cash and revolving-facility availability on February 25, 2021, after borrowing $600 million under its revolver in February.
- Investment and retirement plans: Management estimated 2021 capital expenditures and nuclear fuel purchases of approximately $1.379 billion, including $687 million for growth and development. Planned projects include up to 668 MW of Texas solar and 260 MW of Texas battery storage. Vistra announced plans to retire approximately 6,901 MW of coal and gas capacity by year-end 2027, in addition to other announced retirements, citing economics, environmental compliance costs and emissions reduction goals.
- Debt and liquidity: Management stated it expected sufficient liquidity for anticipated requirements through at least the next 12 months, based on internal forecasts. The company has non-investment-grade credit ratings, variable-rate debt and material collateral requirements tied to commodity markets. Debt covenants, refinancing access and collateral needs remain relevant risks.
- Environmental and legal exposure: CCR groundwater remediation, coal ash closure, emissions rules and changing federal and state climate policy could increase costs or accelerate plant retirements. The filing says the full potential cost of some remediation obligations is not yet clear. The Texas Attorney General and ERCOT requested information following Uri; Vistra said it was cooperating and could not estimate the effect of possible investigations or regulatory changes.
- Other financial judgments: Commodity derivatives are generally marked to market without hedge accounting, creating earnings volatility. The company reported $450 million carrying value for its Tax Receivable Agreement obligation and estimated approximately $1.4 billion of undiscounted future payments. Annual impairment testing found no goodwill impairment, but $356 million of long-lived asset impairments were recorded in 2020.
- Capital returns: Vistra paid $266 million in dividends in 2020. The board declared a $0.15-per-share quarterly dividend for March 2021 and authorized a new $1.5 billion repurchase program effective January 1, 2021; $125 million of shares had been repurchased through February 23, 2021. Future dividends and repurchases remain subject to board decisions, liquidity, market conditions and debt restrictions.
- COVID-19: Management reported no material adverse impact on 2020 results and no material operating disruption to date, while noting continued uncertainty about longer-term effects.
Most important facts for investors to verify
- Track the final accounting and cash effects of Winter Storm Uri, including ERCOT settlements, collateral requirements, litigation and any market or regulatory resettlement.
- Reconcile debt and liquidity after the February 2021 revolver borrowing and storm-related collateral postings; review maturities, covenants and refinancing needs.
- Assess whether the announced plant retirements and solar and storage projects proceed on schedule, within budget and with the expected economics.
- Review the assumptions behind the $356 million impairment, asset-retirement obligations, coal ash remediation estimates and the $450 million TRA carrying value.
- Separate GAAP earnings from Adjusted EBITDA and evaluate the effects of unrealized commodity and interest-rate derivative marks on reported results.
- Note that Deloitte issued an unqualified opinion on the financial statements and internal controls; management also reported effective disclosure controls and internal control over financial reporting at December 31, 2020.
