Focusing on our

# Core Utility Businesses

2021 Annual Report



2021 was a year of outstanding performance for CenterPoint Energy, led by achieving an important milestone toward the execution of our long-term growth strategy and focus on our core utility businesses. We set clear priorities to invest in the safety, reliability and resiliency of our electric and natural gas systems to drive industry-leading growth, while also advancing the transition to a cleaner energy future.

As we look ahead to 2022 and beyond, we remain committed to growing our utilities and optimizing the advantages of this growth for our customers, shareholders and communities. We expect to continue to deliver on the following 10-year value proposition:

• Achieving our industry-leading long-term annual consolidated non-GAAP earnings per share (non-GAAP EPS) growth target of 8% through 2024 and 6-8% through 2030;

• Growing our dividends per share in line with non-GAAP EPS growth over that same period;

• Investing in a $40 billion-plus capital program to continue improving the safety, reliability and resiliency of our electric and natural gas systems;

• Funding our growth with no external equity issuance planned through 2030 by efficiently recycling capital;

• Fully exiting our midstream investments no later than December 2022;

• Progressing toward our milestones to achieve our industry-leading goal of Net Zero direct emissions by 2035, which is approximately 15 years ahead of our peers' average;

• Maintaining a healthy balance sheet; and

• Striving to keep rates affordable for our customers through operations and maintenance (O&M) expense reductions of 1-2% on average annually through 2030, coupled with strong and consistent customer growth.

Our Electric business has more than 2.8 million metered customers in the greater Houston area and southwestern Indiana, as well as 1,300 megawatts (MWs) of electric generation capacity in Indiana. We plan to focus nearly half of our planned $23 billion of electric capital on system growth and improvements, including major investments in our transmission and distribution systems.

Execution of our strategy in our Electric business includes strengthening our infrastructure and preparing for extreme weather events. Working with regulators and other stakeholders, we have taken steps to harden our transmission system, weatherize and inspect facilities covered by new Texas requirements, and leverage enhanced system load rotation automation technology that we anticipate will allow customers to have more regular and predictable outage intervals should a load shed event occur. Additionally, CenterPoint Energy has entered into a contract for temporary emergency mobile generation for use in certain widespread power outages as allowed by new Texas legislation, and processed more than 100 critical load applications related to the natural gas industry since the winter storm in February 2021.

We are working on clean energy investments in Indiana and Texas. With significant coal power plant retirements planned over the next several years, we believe we have a path to successful execution with our renewable investments in Indiana, including our expectation to energize approximately 1,000 MWs by the end of 2024.

CenterPoint Energy and the City of Houston recently launched Resilient Now, a first-of-its-kind collaborative framework to develop a regional master energy plan to enhance local power resilience across the greater Houston area. The company will work jointly with individual communities across the area to optimize infrastructure investments and advance energy solutions to address weather-related challenges. The collaborative plan will also create the blueprint for a sustainable future through increased electric transportation and more renewable energy, such as solar and wind.

In our Natural Gas business, as our approximately 4.2 million customers in our six-state service territory continue to choose natural gas as their preferred energy source, we are committed to investing in a more modern and resilient network for enhanced safety and environmental performance.
Execution of our strategy in our Natural Gas business will be driven by a $16 billion natural gas capital plan, the majority of which is focused on modernizing our distribution system by replacing legacy steel, cast-iron and vintage plastic systems, as well as extending new infrastructure to serve the growing populations in our jurisdictions. In fact, our customer base is expected to grow more than 1% per year through 2030. In 2021, our natural gas utility performed in the top quartile of O&M costs per customer among our peers, and we continue to be a top five natural gas utility in number of customers and top three in miles of main pipelines.

We anticipate an approximately 33% reduction in methane emissions by 2035 resulting from our pipeline modernization efforts. In Minnesota, we secured passage of the bipartisan Natural Gas Innovation Act in 2021, allowing us to invest in new clean energy resources and technologies to reduce emissions.

Our investments also include converting our customer meter infrastructure to help enable automatic and remote shut-off capabilities under certain conditions. While we have used remote-reading capabilities for many years, these new features are designed to enhance the safety and delivery of natural gas to our customers. We expect to have approximately 250,000 customers with these new meter capabilities by the end of 2022.

Throughout the year, our employees demonstrated their dedication to our communities. Faced with several natural disasters, our employees answered the call.

In February 2021, when severe winter weather impacted much of the nation and a power generation shortfall occurred in Texas, our employees went above and beyond to deliver electricity as soon as it was available and keep the natural gas flowing to our customers. When Hurricane Nicholas approached Texas in September 2021, our employees were ready to support our customers and communities. Following the storm’s landfall, our electric crews restored nearly 300,000 customers in less than 12 hours. Despite Hurricane Nicholas’ impact, we maintained reliable natural gas service to our customers.

Our successful performance is a testament to our employees, who validate our values of Safety, Integrity, Accountability, Initiative and Respect through their actions and commitments. We want to express our continued appreciation to them—especially our field and control center colleagues—as they have worked throughout the COVID-19 pandemic to enable us to safely and reliably serve our millions of customers.

In closing, we would like to thank our customers, shareholders and communities for their trust and confidence in us as we continue to execute on our long-term growth strategy and focus on our core utility businesses. At CenterPoint Energy, we believe the best is yet to come.

## Electric (CenterPoint Energy)

The Electric reportable segment is comprised of Houston Electric and Indiana Electric.

For information regarding the properties of the Electric reportable segment, please read “Properties — Electric (CenterPoint Energy and Houston Electric)” in Item 2 of this report, which information is incorporated herein by reference.

## Houston Electric (CenterPoint Energy and Houston Electric)

Houston Electric is a transmission and distribution electric utility that operates wholly within the state of Texas and is a member of ERCOT. ERCOT serves as the independent system operator and regional reliability coordinator for member electric power systems in most of Texas. The ERCOT market represents approximately 90% of the demand for power in Texas and is one of the nation's largest power markets. The ERCOT market operates under the reliability standards developed by the NERC, approved by the FERC and monitored and enforced by the Texas RE. The PUCT has primary jurisdiction over the ERCOT market to ensure the adequacy and reliability of electricity supply across the state's main interconnected power transmission grid. Houston Electric does not make direct retail or wholesale sales of electric energy or own or operate any power generation generating facilities other than leasing facilities that provide temporary emergency electric energy to aid in restoring power to distribution customers during certain widespread power outages as allowed by a new law enacted after the February 2021 Winter Storm Event.

## Electric Transmission

On behalf of REPs, Houston Electric delivers electricity from power plants to substations, from one substation to another and to retail electric customers taking power at or above 69 kV in locations throughout Houston Electric’s certificated service territory. Houston Electric constructs and maintains transmission facilities and provides transmission services under tariffs approved by the PUCT.



The ERCOT ISO is responsible for operating the bulk electric power supply system in the ERCOT market. Houston Electric’s transmission business, along with those of other owners of transmission facilities in Texas, supports the operation of the ERCOT ISO. Houston Electric participates with the ERCOT ISO and other ERCOT utilities to plan, design, obtain regulatory approval for and construct new transmission lines necessary to increase bulk power transfer capability and to remove existing constraints on the ERCOT transmission grid.

## Electric Distribution

In ERCOT, end users purchase their electricity directly from certificated REPs. Houston Electric’s distribution network receives electricity from the transmission grid through power distribution substations and delivers electricity for REPs in its certificated service area by carrying lower-voltage power from the substation to the retail electric customer through distribution feeders. Houston Electric’s operations include construction and maintenance of distribution facilities, metering services, outage response services and call center operations. Houston Electric provides distribution services under tariffs approved by the PUCT. PUCT rules and market protocols govern the commercial operations of distribution companies and other market participants. Rates for these services are established pursuant to rate proceedings conducted before municipalities that have original jurisdiction and the PUCT.

## Bond Companies

Houston Electric has special purpose subsidiaries consisting of the Bond Companies, which it consolidates. These consolidated special purpose subsidiaries are wholly-owned, bankruptcy remote entities that were formed solely for the purpose of purchasing and owning transition or system restoration property through the issuance of Securitization Bonds, and conducting activities incidental thereto. The Securitization Bonds are repaid through charges imposed on customers in Houston Electric’s service territory. For further discussion of the Securitization Bonds and the outstanding balances as of December 31, 2021 and 2020, see Note 14 to the consolidated financial statements.

## Customers

Houston Electric serves nearly all of the Houston/Galveston metropolitan area near the Texas gulf coast. As of December 31, 2021, Houston Electric’s customers consisted of approximately 59 REPs, which sell electricity to approximately 2.7 million metered customers in Houston Electric’s certificated service area, and municipalities, electric cooperatives and other distribution companies located outside Houston Electric’s certificated service area. Each REP is licensed by, and must meet minimum creditworthiness criteria established by, the PUCT. Houston Electric does not have long-term contracts with any of its customers. It operates using a continuous billing cycle, with meter readings being conducted and invoices being distributed to REPs each business day. For information regarding Houston Electric’s major customers, see Note 18 to the consolidated financial statements.

The table below reflects the number of metered customers in Houston Electric’s service area as of December 31, 2021:

<table><tr><td></td><td>Residential</td><td>Commercial/ Industrial</td><td>Total Customers</td></tr><tr><td>Texas gulf coast</td><td>2,359,168</td><td>301,770</td><td>2,660,938</td></tr></table>

## Competition

There are no other electric transmission and distribution utilities in Houston Electric’s service area. For another provider of transmission and distribution services to provide such services in Houston Electric’s territory, it would be required to obtain a certificate of convenience and necessity from the PUCT and, depending on the location of the facilities, may also be required to obtain franchises from one or more municipalities. Houston Electric is not aware of any other party intending to enter this business in its service area at this time. Distributed generation (i.e., power generation located at or near the point of consumption) could result in a reduction of demand for Houston Electric’s distribution services but has not been a significant factor to date.

## Seasonality

Houston Electric’s revenues are primarily derived from rates that it collects from each REP based on the amount of electricity it delivers on behalf of that REP. Houston Electric’s revenues and results of operations are subject to seasonality, weather conditions and other changes in electricity usage, with revenues generally being higher during the warmer months when more electricity is used for cooling purposes.



## Franchises

Houston Electric holds non-exclusive franchises from certain incorporated municipalities in its service territory. In exchange for the payment of fees, these franchises give Houston Electric the right to use the streets and public rights-of-way of these municipalities to construct, operate and maintain its transmission and distribution system and to use that system to conduct its electric delivery business and for other purposes that the franchises permit. The terms of the franchises, with various expiration dates, typically range from 30 to 40 years.

## Indiana Electric (CenterPoint Energy)

Indiana Electric consists of SIGECO’s electric transmission and distribution services, including its power generating and wholesale power operations. As of December 31, 2021, Indiana Electric supplied electric service to the following:

<table><tr><td></td><td>Residential</td><td>Commercial/ Industrial</td><td>Total Customers</td></tr><tr><td>Southwestern Indiana</td><td>131,125</td><td>19,257</td><td>150,382</td></tr></table>

## System Load

Total load and the related reserve margin at the time of the system summer peak on August 26, 2021, is presented below in MW, except for reserve margin at peak.

<table><tr><td></td><td>2021</td></tr><tr><td>Total load at peak</td><td>1,003</td></tr><tr><td>Generating capability</td><td>1,217</td></tr><tr><td>Purchase supply (effective capacity)</td><td>38</td></tr><tr><td>Interruptible contracts &amp; direct load control</td><td>36</td></tr><tr><td>Total power supply capacity</td><td>1,291</td></tr><tr><td>Reserve margin at peak</td><td>29 %</td></tr></table>

The winter peak load for the 2020-2021 season of approximately 742 MW occurred on February 15, 2021.

## Solar

Indiana Electric’s most recently completed 50 MW solar array, which was approved by the IURC in 2018, was placed into service in early 2021 and consists of approximately 150,000 solar panels distributed across 300 acres along Indiana State Road 545 between Troy and New Boston, Indiana. Indiana Electric entered into a BTA with a subsidiary of Capital Dynamics to build a 300 MW solar array in Posey County, Indiana. Indiana Electric received approval from the IURC on October 27, 2021. Subsequently, due to the rising costs for the project, caused in part by supply chain issues in the energy industry and the rising costs of commodities, we, along with Capital Dynamics, recently announced plans to downsize the project to approximately 200 MW. Indiana Electric collaboratively agreed to the scope change and is currently working through contract negotiations, contingent on further IURC review and approval. Indiana Electric also received approval to purchase 100 MW of solar power in Warrick County, Indiana, under a 25-year PPA, with the related solar array expected to be completed in late 2023. Commercial operation is currently projected to begin in 2024.

## Coal Purchases

Coal for coal-fired generating stations has been supplied from operators of nearby coal mines as there are substantial coal reserves in the southern Indiana area. Approximately 2.2 million tons were purchased for generating electricity during 2021. Indiana Electric’s coal inventory was approximately 246,000 tons as of December 31, 2021. The average cost of coal per ton purchased and delivered in 2021 was $52.02. Since August 2014, Indiana Electric has purchased substantially all of its coal from Sunrise Coal, LLC.



As part of its power portfolio, Indiana Electric is a 1.5% shareholder in the OVEC, and based on its participation in the ICPA between OVEC and its shareholder companies, many of whom are regulated electric utilities, Indiana Electric has the right to 1.5% of OVEC's generating capacity output, which, as of December 31, 2021, was approximately 32 MW. Per the ICPA, Indiana Electric is charged demand charges which are based on OVEC's operating expenses, including its financing costs. Those demand charges are available to pass through to customers under Indiana Electric's fuel adjustment clause. Under the ICPA, and while OVEC's plants are operating, Indiana Electric is severally responsible for its share of OVEC's debt obligations. Based on OVEC's current financing, as of September 30, 2021, Indiana Electric's 1.5% share of OVEC's debt obligation equates to between $17 million and $20 million, depending on revolving capacity commitments. Moody's rates OVEC one notch below investment grade, with a positive outlook. Fitch rates OVEC BBB- with a stable outlook. S&P Global withdrew its ratings on January 9, 2020 at OVEC's request. In 2021, Indiana Electric purchased approximately 134 GWh from OVEC. If a default were to occur by a member, any reallocation of the existing debt requires consent of the remaining ICPA participants. If any such reallocation were to occur, Indiana Electric would expect to recover any related costs through the fuel adjustment clause, as it does currently for its 1.5% share.

In April 2008, Indiana Electric executed a capacity contract with Benton County Wind Farm, LLC to purchase as much as 30 MW from a wind farm located in Benton County, Indiana, with IURC approval. The contract expires in 2029. Indiana Electric purchased approximately 77 GWh under this contract in 2021. In December 2009, Indiana Electric executed a 20-year power purchase agreement with Fowler Ridge II Wind Farm, LLC to purchase as much as 50 MW of energy from a wind farm located in Benton and Tippecanoe Counties in Indiana, with the approval of the IURC. Indiana Electric purchased approximately 129 GWh under this contract in 2021. In total, wind resources provided approximately 3% of total GWh sourced in 2021.

## MISO Related Activity

Indiana Electric is a member of the MISO, a FERC approved regional transmission organization. The MISO serves the electric transmission needs of much of the Midcontinent region and maintains operational control over Indiana Electric's electric transmission facilities as well as other utilities in the region. Indiana Electric is an active participant in the MISO energy markets, where it bids its generation into the Day Ahead and Real Time markets and procures power for its retail customers at Locational Marginal Price as determined by the MISO market. MISO-related purchase and sale transactions are recorded using settlement information provided by the MISO. These purchase and sale transactions are accounted for on at least a net hourly position. During 2021, in intervals when purchases from the MISO were in excess of generation sold to the MISO, the net purchases were 83 GWh. During the year ended December 31, 2021, in intervals when sales to the MISO were in excess of purchases from the MISO, the net sales were 1,457 GWh.

## Interconnections

As of December 31, 2021, Indiana Electric had interconnections with Louisville Gas and Electric Company, Duke Energy Shared Services, Inc., Indianapolis Power & Light Company, Hoosier Energy Rural Electric Cooperative, Inc. and Big Rivers Electric Corporation providing the ability to simultaneously interchange approximately 750 MW during peak load periods. Indiana Electric, as required as a member of the MISO, has turned over operational control of the interchange facilities and its own transmission assets to the MISO. Indiana Electric, in conjunction with the MISO, must operate the bulk electric transmission system in accordance with NERC Reliability Standards. As a result, interchange capability varies based on regional transmission system configuration, generation dispatch, seasonal facility ratings and other factors. Indiana Electric is in compliance with reliability standards promulgated by the NERC.

## Competition

There are no other electric transmission and distribution utilities in Indiana Electric’s service area. Indiana Electric is a vertically integrated utility that owns the generation, transmission, and distribution components of a utility.

For another provider of transmission and distribution services to provide such services in Indiana Electric’s territory, it would be required to obtain IURC approval of such service territory. Indiana service territory certificates are exclusive. Distributed generation (i.e., power generation located at or near the point of consumption) could result in reduced demand for Indiana Electric’s distribution services but has not been a significant factor to date.



Indiana Electric’s revenues are primarily derived from rates that it collects from customers in its service territory based on the amount of electricity it delivers. Indiana Electric’s revenues and results of operations are subject to seasonality, weather conditions and other changes in electricity usage, with revenues generally being higher during the warmer months when more electricity is used for cooling purposes, and during the cooler months when more electricity is used for heating purposes.

## Natural Gas (CenterPoint Energy and CERC)

CenterPoint Energy’s and CERC’s Natural Gas engage in regulated intrastate natural gas sales and natural gas transportation and storage for residential, commercial, industrial and transportation customers. See the detail of customers by state below. CenterPoint Energy’s and CERC’s Natural Gas provide permanent pipeline connections through interconnects with various interstate and intrastate pipeline companies through CEIP. CenterPoint Energy’s and CERC’s Natural Gas also provided services in Minnesota consisting of residential appliance repair and maintenance services along with HVAC equipment sales and home repair protection plans to natural gas customers in Arkansas, Indiana, Mississippi, Ohio, Oklahoma and Texas through a third party as of December 31, 2021.

The largest metropolitan areas served in each state were Houston, Texas; Minneapolis, Minnesota; Little Rock, Arkansas; Shreveport, Louisiana; Biloxi, Mississippi; Lawton, Oklahoma; Evansville, Indiana; and Dayton, Ohio.

## Seasonality

The demand for natural gas sales to residential customers and natural gas sales and transportation for commercial and industrial customers is seasonal and affected by variations in weather conditions. In 2021, approximately 68% of CenterPoint



Energy’s Natural Gas total throughput and 68% of CERC’s Natural Gas total throughput occurred in the first and fourth quarters. These patterns reflect the higher demand for natural gas for heating purposes during the colder months.

Supply and Transportation. In 2021, CenterPoint Energy’s Natural Gas purchased virtually all of its natural gas supply pursuant to contracts with remaining terms varying from a few months to three-year terms. Major suppliers are those that account for greater than 10% of CenterPoint Energy’s or CERC’s annual natural gas supply purchases. In 2021, CenterPoint Energy and CERC purchased 42% and 43%, respectively, of their natural gas supply from three major suppliers. For CenterPoint Energy, the suppliers were Macquarie Energy, LLC (18%), Tenaska Marketing Ventures, LLC (13%) and BP Energy Company/BP Canada Energy Marketing (11%). For CERC, the suppliers were Macquarie Energy, LLC (23%), BP Energy Company/BP Canada Energy Marketing (10%) and Spire Marketing, Inc. (10%). Numerous other suppliers provided the remainder of CenterPoint Energy’s and CERC’s natural gas supply requirements.

CenterPoint Energy’s and CERC’s Natural Gas transports their natural gas supplies through various intrastate and interstate pipelines under contracts with remaining terms, including extensions, varying from one to fifteen years. CenterPoint Energy’s and CERC’s Natural Gas anticipates that these gas supply and transportation contracts will be renewed or replaced prior to their expiration.

CenterPoint Energy’s and CERC’s Natural Gas actively engage in commodity price stabilization pursuant to annual gas supply plans presented to and/or filed with each of its state regulatory authorities. These price stabilization activities include use of storage gas and contractually establishing structured prices (e.g., fixed price, costless collars and caps) with CenterPoint Energy’s and CERC’s Natural Gas’ physical gas suppliers. Their gas supply plans generally call for 50–75% of normal winter supplies to be stabilized in some fashion.

The regulations of the states in which CenterPoint Energy’s and CERC’s Natural Gas operate allow them to pass through changes in the cost of natural gas, including savings and costs of financial derivatives associated with the index-priced physical supply, to their customers under purchased gas adjustment provisions in their tariffs. Depending upon the jurisdiction, the purchased gas adjustment factors are updated periodically, ranging from monthly to semi-annually. The changes in the cost of gas billed to customers are subject to review by the applicable regulatory bodies.

CenterPoint Energy’s and CERC’s Natural Gas use various third-party storage services or owned natural gas storage facilities to meet peak-day requirements and to manage the daily changes in demand due to changes in weather. CenterPoint Energy’s and CERC’s Natural Gas may also supplement contracted supplies and storage from time to time with stored LNG and propane-air plant production.

As of December 31, 2021, CenterPoint Energy’s and CERC’s Natural Gas owned and operated the following natural gas facilities:

The table below reflects CenterPoint Energy’s and CERC’s Natural Gas contracted upstream storage services as of December 31, 2021:

<table><tr><td></td><td>Storage Capacity (Bcf)</td><td>Maximum Peak Daily Delivery (MMcf)</td></tr><tr><td>CenterPoint Energy</td><td></td><td></td></tr><tr><td>Upstream Storage Service</td><td>115</td><td>2,744</td></tr><tr><td>CERC</td><td></td><td></td></tr><tr><td>Upstream Storage Service</td><td>92</td><td>2,298</td></tr></table>

On an ongoing basis, CenterPoint Energy’s and CERC’s Natural Gas enter into contracts to provide sufficient supplies and pipeline capacity to meet their customer requirements. However, it is possible for limited service disruptions to occur from time to time due to weather conditions, transportation constraints and other events. As a result of these factors, supplies of natural gas may become unavailable from time to time, or prices may increase rapidly in response to temporary supply constraints or other factors.

Upon expiration of the AMAs with the Energy Services Disposal Group discussed in Note 4 to the consolidated financial statements, CenterPoint Energy’s and CERC’s Natural Gas businesses entered into new third-party AMAs beginning in April 2021 associated with their utility distribution service in Arkansas, Indiana, Louisiana, Mississippi, Oklahoma and Texas. Additionally, CenterPoint Energy’s and CERC’s Natural Gas business in Minnesota entered into a third-party AMA beginning in February 2021. The AMAs have varying terms, the longest of which expires in 2027. Pursuant to the provisions of the agreements, CenterPoint Energy’s and CERC’s Natural Gas either sells natural gas to the asset manager and agrees to repurchase an equivalent amount of natural gas throughout the year at the same cost, or simply purchases its full natural gas requirements at each delivery point from the asset manager. Generally, AMAs are contracts between CenterPoint Energy’s and CERC’s Natural Gas and an asset manager that are intended to transfer the working capital obligation and maximize the utilization of the assets. In these agreements, CenterPoint Energy’s and CERC’s Natural Gas agrees to release transportation and storage capacity to other parties to manage natural gas storage, supply and delivery arrangements for CenterPoint Energy’s and CERC’s Natural Gas and to use the released capacity for other purposes when it is not needed for CenterPoint Energy’s and CERC’s Natural Gas. CenterPoint Energy’s and CERC’s Natural Gas may receive compensation from the asset manager through payments made over the life of the AMAs. CenterPoint Energy’s and CERC’s Natural Gas has an obligation to purchase their winter storage requirements that have been released to the asset manager under these AMAs. For amounts outstanding under these AMAs, see Notes 4 and 14 to the consolidated financial statements.

## Competition

CenterPoint Energy’s and CERC’s Natural Gas competes primarily with alternate energy sources such as electricity and other fuel sources. In some areas, intrastate pipelines, other gas distributors and marketers also compete directly for gas sales to end users. In addition, as a result of federal regulations affecting interstate pipelines, natural gas marketers operating on these pipelines may be able to bypass CenterPoint Energy’s and CERC’s Natural Gas’ facilities and market, sell and/or transport natural gas directly to commercial and industrial customers.

## Corporate and Other (CenterPoint Energy)

CenterPoint Energy’s Corporate and Other consists of energy performance contracting and sustainable infrastructure services, such as renewables, distributed generation and combined heat and power projects, through Energy Systems Group, and other corporate support operations that support CenterPoint Energy’s business operations. CenterPoint Energy’s Corporate and Other also includes office buildings and other real estate used for business operations.

## REGULATION

The Registrants are subject to regulation by various federal, state and local governmental agencies, including the regulations described below. The following discussion is based on regulation in the Registrants’ businesses as of December 31, 2021.



## Federal Energy Regulatory Commission

The FERC has jurisdiction under the NGA and the NGPA, as amended, to regulate the transportation of natural gas in interstate commerce and natural gas sales for resale in interstate commerce that are not first sales. The FERC regulates, among other things, the construction of pipeline and related facilities used in the transportation and storage of natural gas in interstate commerce, including the extension, expansion or abandonment of these facilities. The FERC also regulates the transmission and wholesale sales of electricity in interstate commerce, mergers, acquisitions and corporate transactions by electricity companies, energy markets, reliability standards and the issuance of short-term debt by public utilities regulated by FERC. The FERC has authority to prohibit market manipulation in connection with FERC-regulated transactions, to conduct audits and investigations, and to impose significant civil penalties (up to approximately $1.4 million per day per violation, subject to periodic adjustment to account for inflation) for statutory violations and violations of the FERC’s rules or orders.

Indiana Electric is a “public utility” under the FPA and is subject to regulation by the FERC. Houston Electric is not a “public utility” under the FPA and, therefore, is not generally regulated by the FERC, although certain of its transactions are subject to limited FERC jurisdiction. The FERC has certain responsibilities with respect to ensuring the reliability of electric transmission service, including transmission facilities owned by Houston Electric and other utilities within ERCOT. The FERC has designated the NERC as the ERO to promulgate standards, under FERC oversight, for all owners, operators and users of the bulk power system. The ERO and the FERC have authority to (a) impose fines and other sanctions on applicable entities that fail to comply with approved standards and (b) audit compliance with approved standards. The FERC has approved the delegation by the NERC of authority for reliability in ERCOT to the Texas RE and in MISO to ReliabilityFirst Corporation. Neither Houston Electric nor Indiana Electric anticipate that the reliability standards proposed by the NERC and approved by the FERC will have a material adverse impact on their operations. To the extent that Houston Electric and Indiana Electric are required to make additional expenditures to comply with these standards, it is anticipated that Houston Electric and Indiana Electric will seek to recover those costs through the transmission charges that are imposed on all distribution service providers within ERCOT and the MISO, respectively, for electric transmission provided.

As a public utility holding company, under the Public Utility Holding Company Act of 2005, CenterPoint Energy and its consolidated subsidiaries are subject to reporting and accounting requirements and are required to maintain certain books and records and make them available for review by the FERC and state regulatory authorities in certain circumstances.

For a discussion of the Registrants’ ongoing regulatory proceedings, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters” in Item 7 of Part II of this report, which discussion is incorporated herein by reference.

## State and Local Regulation – Electric Transmission & Distribution (CenterPoint Energy and Houston Electric)

Houston Electric conducts its operations pursuant to a certificate of convenience and necessity issued by the PUCT that covers its present service area and facilities. The PUCT and certain municipalities have the authority to set the rates and terms of service provided by Houston Electric under cost-of-service rate regulation. Houston Electric holds non-exclusive franchises from certain incorporated municipalities in its service territory. In exchange for payment of fees, these franchises give Houston Electric the right to use the streets and public rights-of-way of these municipalities to construct, operate and maintain its transmission and distribution system and to use that system to conduct its electric delivery business and for other purposes that the franchises permit. The terms of the franchises, with various expiration dates, typically range from 30 to 40 years.

Houston Electric’s distribution rates charged to REPs for residential and small commercial customers are primarily based on amounts of energy delivered, whereas distribution rates for a majority of large commercial and industrial customers are primarily based on peak demand. All REPs in Houston Electric’s service area pay the same rates and other charges for transmission and distribution services. This regulated delivery charge may include the transmission and distribution rate (which includes municipal franchise fees), a distribution recovery mechanism for recovery of incremental distribution-invested capital above that which is already reflected in the base distribution rate, a nuclear decommissioning charge associated with decommissioning the South Texas nuclear generating facility, an EECRF charge, and charges associated with securitization of regulatory assets, stranded costs and restoration costs relating to Hurricane Ike. Transmission rates charged to distribution companies are based on amounts of energy transmitted under “postage stamp” rates that do not vary with the distance the energy is being transmitted. All distribution companies in ERCOT pay Houston Electric the same rates and other charges for transmission services.

With the IURC’s approval, Indiana Electric is a member of the MISO, a FERC-approved regional transmission organization. The MISO serves the electrical transmission needs of much of the Midcontinent region and maintains operational control over Indiana Electric’s electric transmission and generation facilities as well as those of other utilities in the region.



Indiana Electric is an active participant in the MISO energy markets, bidding its owned generation into the Day Ahead and Real Time markets and procuring power for its retail customers at Locational Marginal Pricing as determined by the MISO market. Indiana Electric also receives transmission revenue that results from other members' use of Indiana Electric's transmission system. Generally, these transmission revenues, along with costs charged by the MISO, are considered components of base rates and any variance from that included in base rates is recovered from or refunded to retail customers through tracking mechanisms.

For a discussion of certain of Houston Electric’s and Indiana Electric’s ongoing regulatory proceedings, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters” in Item 7 of Part II of this report, which discussion is incorporated herein by reference.

## State and Local Regulation – Electric Generation (CenterPoint Energy)

Indiana Electric owns and operates 1,000 MW of coal-fired generation, 163 MW of gas-fired generation and 54 MW of solar generation. Indiana Electric’s newest in-service solar array, which was approved by the IURC in 2018, consists of approximately 150,000 solar panels distributed across 300 acres along Indiana State Road 545 between Troy and New Boston, Indiana. The 50 MW universal solar array was placed in service for southwestern Indiana electric customers in early 2021. On February 9, 2021, Indiana Electric entered into a BTA with a subsidiary of Capital Dynamics. Pursuant to the BTA, Capital Dynamics, with its partner Tenaska, contracted to build a 300 MW solar array in Posey County, Indiana through a special purpose entity, Posey Solar. Upon completion of construction, currently projected to be at the end of 2023, and subject to IURC approval, which was received on October 27, 2021, Indiana Electric will acquire Posey Solar and its solar array assets for a fixed purchase price. Due to rising cost for the project, caused in part by supply chain issues in the energy industry and the rising costs of commodities, we, along with Capital Dynamics, recently announced plans to downsize the project to approximately 200 MW. Indiana Electric collaboratively agreed to the scope change and is currently working through contract negotiations, contingent on further IURC review and approval. Indiana Electric also received approval to purchase 100 MW of solar power in Warrick County, Indiana, under a 25 year PPA, with the related solar array expected to be completed in late 2023. Indiana Electric has also sought approval to purchase 185 MW of solar power in Vermillion County, Indiana, under a 15-year PPA, and 150 MW of solar power in Knox County, Indiana, under a 20-year PPA. Subject to necessary approvals, both solar arrays are expected to be in service by 2023. Indiana Electric also is party to two PPAs, entitling it to the delivery of up to 80 MW of electricity produced by wind turbines. The energy and capacity secured from Indiana Electric’s available generation resources are utilized primarily to serve the needs of retail electric customers residing within Indiana Electric’s franchised service territory. Costs of operating Indiana Electric’s generation facilities are recovered through IURC-approved base rates as well as periodic rate recovery mechanisms including the CECA, ECA, FAC, MCRA, and RCRA Mechanism. Costs that are deemed unreasonable or imprudent by the IURC may not be recoverable through retail electric rates. Indiana Electric also receives revenues from the MISO to compensate it for benefits the generation facilities provide to the transmission system. Proceeds from the sales of energy from Indiana Electric’s generation facilities that exceed the requirements of retail customers are shared by Indiana Electric and retail electric customers.

The generation facilities owned and operated by Indiana Electric are subject to various environmental regulations enforced by the EPA and the IDEM. Operations of Indiana Electric’s generation facilities are subject to regulation by the EPA and the IDEM as it pertains to the discharge of constituents from the generation facilities. For further discussion, see “Our Business — Environmental Matters” below.

## State and Local Regulation – Natural Gas (CenterPoint Energy and CERC)

In almost all communities in which CenterPoint Energy’s and CERC’s Natural Gas provides natural gas distribution services, they operate under franchises, certificates or licenses obtained from state and local authorities. The original terms of the franchises, with various expiration dates, typically range from 20 to 30 years. CenterPoint Energy’s and CERC’s Natural Gas expects to be able to renew expiring franchises. In most cases, franchises to provide natural gas utility services are not exclusive.

Substantially all of CenterPoint Energy’s and CERC’s Natural Gas is subject to cost-of-service rate regulation by the relevant state public utility commissions and, in Texas, by those municipalities that have retained original jurisdiction. In certain of the jurisdictions in which they operate, CenterPoint Energy’s and CERC’s Natural Gas has annual rate adjustment mechanisms that provide for changes in rates dependent upon certain changes in invested capital, earned returns on equity or actual margins realized.

For a discussion of certain of CenterPoint Energy’s and CERC’s Natural Gas’ ongoing regulatory proceedings, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters” in Item 7 of Part II of this report, which discussion is incorporated herein by reference.



## Department of Transportation (CenterPoint Energy and CERC)

CenterPoint Energy and CERC are subject to regulation by PHMSA under the NGPSA and the HLPSA. The NGPSA delegated to PHMSA through DOT the authority to regulate gas pipelines. The HLPSA delegated to PHMSA through DOT the authority to develop, prescribe and enforce federal safety standards for the transportation of hazardous liquids by pipeline. Every four years PHMSA is up for reauthorization by Congress and with that reauthorization comes changes to the legislative requirements that Congress sets forth for the oversight of natural gas and hazardous liquid pipelines. In 2020, the Pipes Act was enacted. The Pipes Act reauthorized PHMSA through 2023 and imposed a few new mandates on the agency. The law establishes a PHMSA technology pilot, authorizes a new idled pipe operating status and contains process protections for operators during PHMSA enforcement proceedings. Section 114 of the 2020 Pipes Act is a self-mandating rule for natural gas pipeline operations like CERC's. Section 114 focuses on processes and procedures to eliminate or reduce emissions during normal operations. Further, Section 113 of the Pipes Act directed PHMSA to develop regulations to require natural gas pipeline operators to implement leak detection and repair programs. A proposed rule is expected to be released by May 2022.

In January 2021, PHMSA published a final rule amending the federal Pipeline Safety Regulations to ease regulatory burdens on the construction, operation, and maintenance of gas transmission, distribution, and gathering systems.

CenterPoint Energy and CERC anticipate that compliance with PHMSA’s regulations, performance of the remediation activities by CenterPoint Energy’s and CERC’s Natural Gas and intrastate pipelines and verification of records on maximum allowable operating pressure will continue to require increases in both capital expenditures and operating costs. The level of expenditures will depend upon several factors, including age, location and operating pressures of the facilities. In particular, the cost of compliance with the DOT’s integrity management rules will depend on integrity testing and the repairs found to be necessary by such testing. Changes to the amount of pipe subject to integrity management, whether by expansion of the definition of the type of areas subject to integrity management procedures or of the applicability of such procedures outside of those defined areas, may also affect the costs incurred. Implementation by PHMSA of the Pipes Act, in particular Section 113, acts reauthorizing PHMSA or other future acts may result in other regulations or the reinterpretation of existing regulations that could impact compliance costs. In addition, CenterPoint Energy and CERC may be subject to the DOT’s enforcement actions and penalties if they fail to comply with pipeline regulations.

## ENVIRONMENTAL MATTERS

The following discussion is based on environmental matters in the Registrants’ businesses as of December 31, 2021. The Registrants’ operations are subject to stringent and complex laws and regulations pertaining to the environment. As an owner or operator of natural gas pipelines, distribution systems and storage, electric transmission and distribution systems, steam electric and renewable generation systems and the facilities that support these systems, the Registrants must comply with these laws and regulations at the federal, state and local levels. These laws and regulations can restrict or impact the Registrants’ business activities in many ways, including, but not limited to:

• restricting the way the Registrants can handle or dispose of wastes, including wastewater discharges and air emissions;

- limiting or prohibiting construction activities in sensitive areas such as wetlands, coastal regions or areas inhabited by endangered species;

- requiring remedial action and monitoring to mitigate environmental conditions caused by the Registrants’ operations or attributable to former operations;

• enjoining the operations of facilities with permits issued pursuant to such environmental laws and regulations; and

- impacting the demand for the Registrants’ services by directly or indirectly affecting the use or price of fossil fuels, including, but not limited to, natural gas.

To comply with these requirements, the Registrants may need to spend substantial amounts and devote other resources from time to time to, among other activities:

• construct or acquire new facilities and equipment;

• acquire permits for facility operations or purchase emissions allowances;

• modify, upgrade or replace existing and proposed equipment; and

• decommission or remediate waste management areas, fuel storage facilities and other locations.

Failure to comply with these laws and regulations may trigger a variety of administrative, civil and criminal enforcement measures, including the assessment of monetary penalties, revocation of permits, the imposition of remedial actions and monitoring and the issuance of orders enjoining future operations. Certain environmental statutes impose strict, joint and



several liability for costs required to assess, clean up and restore sites where hazardous substances have been stored, disposed or released. Moreover, it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and/or property damage allegedly caused by the release of hazardous substances or other waste products into the environment.

Increasingly, environmental regulation has resulted in more restrictions and limitations on activities that may impact the environment. There can be no assurance as to the amount or timing of future expenditures for environmental compliance or remediation and monitoring, and actual future expenditures may be different from the amounts currently anticipated. The Registrants try to anticipate future regulatory requirements that might be imposed and plan accordingly to maintain compliance with changing environmental laws and regulations.

Based on current regulatory requirements and interpretations, the Registrants do not believe that compliance with federal, state or local environmental laws and regulations will have a material adverse effect on their business, financial position, results of operations or cash flows. In addition, the Registrants believe that their current environmental remediation activities will not materially interrupt or diminish their operational ability. The Registrants cannot provide assurances that future events, such as changes in existing laws, the promulgation of new laws, or the development or discovery of new facts or conditions will not cause them to incur significant costs. The following is a discussion of material current environmental and safety issues, laws and regulations that relate to the Registrants' operations. The Registrants believe that they are in substantial compliance with these environmental laws and regulations.

## Global Climate Change

There is increasing attention being paid in the United States and worldwide to the issue of climate change. As a result, from time to time, regulatory agencies have considered the modification of existing laws or regulations or the adoption of new laws or regulations addressing the emissions of GHG on the state, federal, or international level. On August 3, 2015, the EPA released its CPP rule, which required a 32% reduction in carbon emissions from 2005 levels. The final rule was published in the Federal Register on October 23, 2015, and that action was immediately followed by litigation ultimately resulting in the U.S. Supreme Court staying implementation of the rule. On July 8, 2019, the EPA published the ACE rule, which (i) repealed the CPP rule; (ii) replaced the CPP rule with a program that requires states to implement a program of energy efficiency improvement targets for individual coal-fired electric generating units; and (iii) amended the implementing regulations for Section 111(d) of the Clean Air Act. On January 19, 2021, the majority of the ACE rule — including the CPP repeal, CPP replacement, and the timing-related portions of the Section 111(d) implementing rule — was struck down by the U.S. Court of Appeals for the D.C. Circuit and on October 29, 2021, the U.S. Supreme Court agreed to consider four petitions filed by various coal interests and a coalition of 19 states that seek review of the lower court's decision vacating the ACE rule. CenterPoint Energy is currently unable to predict what a replacement rule for either the ACE rule or CPP would require.

The Biden administration recommitted the United States to the Paris Agreement, which can be expected to drive a renewed regulatory push to require further GHG emission reductions from the energy sector and proceeded to lead negotiations at the global climate conference in Glasgow, Scotland. On April 22, 2021, President Biden announced new goals of 50% reduction of economy-wide GHG emissions, and 100% carbon-free electricity by 2035, which formed the basis of the United States' commitments announced in Glasgow. In September 2021, CenterPoint Energy announced its new net zero emissions goals for both Scope 1 and Scope 2 emissions by 2035 as well as a goal to reduce Scope 3 emissions by 20% to 30% by 2035. Because Texas is an unregulated market, CenterPoint Energy's Scope 2 estimates do not take into account Texas electric transmission and distribution assets in the line loss calculation and exclude emissions related to purchased power in Indiana between 2024 and 2026 as estimated. CenterPoint Energy's Scope 3 estimates do not take into account the emissions of transport customers and emissions related to upstream extraction. These emission goals are expected to be used to position CenterPoint Energy to comply with anticipated future regulatory requirements from the current and future administrations to further reduce GHG emissions. For more information regarding CenterPoint Energy's new net zero emission goals and the risks associated with them, see "Risk Factors — Risk Factors Affecting Our Businesses — CenterPoint Energy is subject to operational and financial risks..." CenterPoint Energy's and CERC's revenues, operating costs and capital requirements could be adversely affected as a result of any regulatory action that would require installation of new control technologies or a modification of their operations or would have the effect of reducing the consumption of natural gas. In addition, the EPA has indicated that it intends to implement new regulations targeting reductions in methane emissions, which are likely to increase costs related to production, transmission and storage of natural gas. Houston Electric, in contrast to some electric utilities including Indiana Electric, does not generate electricity, other than leasing facilities that provide temporary emergency electric energy to aid in restoring power to distribution customers during certain widespread power outages as allowed by a new law enacted after the February 2021 Winter Storm Event, and thus is not directly exposed to the risk of high capital costs and regulatory uncertainties that face electric utilities that burn fossil fuels to generate electricity. CenterPoint Energy's new net zero emissions goals are aligned with Indiana Electric's generation transition plan and are expected to position Indiana Electric to comply with anticipated future regulatory requirements related to GHG emissions reductions.



To the extent climate changes may occur and such climate changes result in warmer temperatures in the Registrants' service territories, financial results from the Registrants' businesses could be adversely impacted. For example, CenterPoint Energy's and CERC's Natural Gas could be adversely affected through lower natural gas sales. On the other hand, warmer temperatures in CenterPoint Energy's and Houston Electric's electric service territory may increase revenues from transmission and distribution and generation through increased demand for electricity for cooling. Another possible result of climate change is more frequent and more severe weather events, such as hurricanes, tornadoes and flooding. Since many of the Registrants' facilities are located along or near the Texas gulf coast, increased or more severe hurricanes or tornadoes could increase costs to repair damaged facilities and restore service to customers. When the Registrants cannot deliver electricity or natural gas to customers, or customers cannot receive services, the Registrants' financial results can be impacted by lost revenues, and they generally must seek approval from regulators to recover restoration costs. To the extent the Registrants are unable to recover those costs, or if higher rates resulting from recovery of such costs result in reduced demand for services, the Registrants' future financial results may be adversely impacted.

## Air Emissions

The Registrants’ operations are subject to the federal Clean Air Act and comparable state laws and regulations. These laws and regulations regulate emissions of air pollutants from various industrial sources, including electric generating facilities and natural gas processing plants and compressor stations, and also impose various monitoring and reporting requirements. Such laws and regulations may require pre-approval for the construction or modification of certain projects or facilities expected to produce air emissions or result in the increase of existing air emissions. The Registrants may be required to obtain and strictly comply with air permits containing various emissions and operational limitations, or utilize specific emission control technologies to limit emissions. Failure to comply with these requirements could result in monetary penalties, injunctions, conditions or restrictions on operations, and potentially criminal enforcement actions. The Registrants may be required to incur certain capital expenditures in the future for air pollution control equipment in connection with obtaining and maintaining operating permits and approvals for air emissions.

## Water Discharges

The Registrants’ operations are subject to the Federal Water Pollution Control Act of 1972, as amended, also known as the Clean Water Act, and analogous state laws and regulations. These laws and regulations impose detailed requirements and strict controls regarding the discharge of pollutants into waters of the United States. The unpermitted discharge of pollutants, including discharges resulting from a spill or leak incident, is prohibited. The Clean Water Act and regulations implemented thereunder also prohibit discharges of dredged and fill material into wetlands and other waters of the United States unless authorized by an appropriately issued permit. Any unpermitted release of petroleum or other pollutants from the Registrants’ pipelines or facilities could result in fines or penalties as well as significant remedial obligations.

## Waters of the United States

Under the Obama administration, the EPA promulgated a set of rules that included a comprehensive regulatory overhaul of defining “waters of the United States” for the purposes of determining federal jurisdiction. The Trump administration signaled its intent to repeal and replace the Obama-era rules. In accordance with this intent, the EPA promulgated a rule in early 2018 that postponed the effectiveness of the Obama-era rules until 2020. Thereafter, the EPA proposed a new set of rules that would narrow the Clean Water Act’s jurisdiction, which were finalized on April 21, 2020. That set of rules was vacated by recent decisions in the U.S. federal district courts in New Mexico and Arizona, and on November 18, 2021, the EPA released a proposal to reestablish the pre-2015 definition of “waters of the United States” which will become effective upon finalization and publication. The potential impact of further revisions to the “waters of the United States” regulations on the Registrants’ business, liabilities, compliance obligations or profits and revenues is uncertain at this time.

## ELG

In 2015, the EPA finalized revisions to the existing steam electric wastewater discharge standards which set more stringent wastewater discharge limits and effectively prohibited further wet disposal of coal ash in ash ponds. These new standards are applied at the time of permit renewal and an affected facility must comply with the wastewater discharge limitations no later than December 31, 2023, and the prohibition of wet sluicing of bottom ash no later than December 31, 2025. In February 2019, the IURC approved Indiana Electric’s ELG compliance plan for its F.B. Culley Generating Station, and Indiana Electric is currently finalizing its ELG compliance plan for the remainder of its affected units as part of its ongoing IRP process.



## Cooling Water Intake Structures

Section 316 of the federal Clean Water Act requires steam electric generating facilities use “best technology available” to minimize adverse environmental impacts on a body of water. In May 2014, the EPA finalized a regulation requiring installation of “best technology available” to mitigate impingement and entrainment of aquatic species in cooling water intake structures. Indiana Electric is currently completing the required ecological studies and anticipates timely compliance in 2022-2023.

## Hazardous Waste

The Registrants’ operations generate wastes, including some hazardous wastes, that are subject to the federal RCRA, and comparable state laws, which impose detailed requirements for the handling, storage, treatment, transport and disposal of hazardous and solid waste. RCRA currently exempts many natural gas gathering and field processing wastes from classification as hazardous waste. Specifically, RCRA excludes from the definition of hazardous waste waters produced and other wastes associated with the exploration, development or production of crude oil and natural gas. However, these oil and gas exploration and production wastes are still regulated under state law and the less stringent non-hazardous waste requirements of RCRA. Moreover, ordinary industrial wastes such as paint wastes, waste solvents, laboratory wastes and waste compressor oils may be regulated as hazardous waste. The transportation of natural gas in pipelines may also generate some hazardous wastes that would be subject to RCRA or comparable state law requirements.

## Coal Ash

Indiana Electric has three ash ponds, two at the F.B. Culley facility (Culley East and Culley West) and one at the A.B. Brown facility. In 2015, the EPA finalized its CCR Rule, which regulates coal ash as non-hazardous material under the RCRA. The final rule allows beneficial reuse of ash, and the majority of the ash generated by Indiana Electric’s generating plants will continue to be beneficially reused. The EPA continues to propose amendments to the CCR Rule; however, under the CCR Rule as it is currently in effect, Indiana Electric is required to perform integrity assessments, including ground water monitoring, at its F.B. Culley and A.B. Brown generating stations. The ground water studies are necessary to determine the remaining service life of the ponds and whether a pond must be retrofitted with liners or closed in place. Preliminary groundwater monitoring indicates potential groundwater impacts very close to Indiana Electric’s ash impoundments, and further analysis is ongoing. The CCR Rule required companies to complete location restriction determinations by October 18, 2018. Indiana Electric completed its evaluation and determined that one F.B. Culley pond (Culley East) and the A.B. Brown pond fail the aquifer placement location restriction. As a result of this failure, Indiana Electric was required to cease disposal of new ash in the ponds and commence closure of the ponds by April 11, 2021. Indiana Electric filed timely requests for extensions available under the CCR Rule that would allow Indiana Electric to continue to use the ponds through October 15, 2023. The inability to take these extensions may result in increased and potentially significant operational costs in connection with the accelerated implementation of an alternative ash disposal system or adversely impact Indiana Electric’s future operations. Failure to comply with these requirements could also result in an enforcement proceeding, including the imposition of fines and penalties. On January 22, 2021, Indiana Electric received letters from the EPA for both the F.B. Culley and A.B. Brown facilities that determined Indiana Electric’s extension submittals complete and extended the compliance deadline of April 11, 2021 until the EPA issues a final decision on the extension requests. The Culley West pond was closed under CCR provisions applicable to inactive ponds, and closure activities were completed in December 2020. For further discussion about Indiana Electric’s ash ponds, please see Note 16(e) to the consolidated financial statements.

## Liability for Remediation

CERCLA, also known as “Superfund,” and comparable state laws impose liability, without regard to fault or the legality of the original conduct, on certain classes of persons responsible for the release of “hazardous substances” into the environment. Classes of PRPs include the current and past owners or operators of sites where a hazardous substance was released and companies that disposed or arranged for the disposal of hazardous substances at offsite locations such as landfills. Although petroleum, as well as natural gas, is expressly excluded from CERCLA’s definition of a “hazardous substance,” in the course of the Registrants’ ordinary operations they do, from time to time, generate wastes that may fall within the definition of a “hazardous substance.” CERCLA authorizes the EPA and, in some cases, third parties to take action in response to threats to the public health or the environment and to recover the costs they incur from the responsible classes of persons. Under CERCLA, the Registrants could potentially be subject to joint and several liability for the costs of cleaning up and restoring sites where hazardous substances have been released, for damages to natural resources, and for associated response and assessment costs, including for the costs of certain health studies.



## Liability for Preexisting Conditions

For information about preexisting environmental matters, please see Note 16(e) to the consolidated financial statements.

## HUMAN CAPITAL

CenterPoint Energy believes its employees are critical to safely delivering electricity and natural gas across its service territories and seeks to create a diverse, inclusive and safe work environment. CenterPoint Energy’s core values—safety, integrity, accountability, initiative and respect—guide how it makes decisions and provide the foundation for a strong culture of ethics where employees are responsible for upholding these values and following CenterPoint Energy’s Ethics and Compliance Code.

The following table sets forth the number of employees by Registrant and reportable segment as of December 31, 2021:

(1) Employees in the Corporate and Other segment provide services to the Electric and Natural Gas segments and the costs of these services have been charged directly to the Electric and Natural Gas segments using assignment methods that management believes are reasonable. For further information, see Note 20 to the consolidated financial statements.

CenterPoint Energy’s workforce includes 3,483 employees represented by collective bargaining agreements. For information about the status of collective bargaining agreements, see Note 8(j) to the consolidated financial statements.

Recruiting, Training and Development. CenterPoint Energy’s human capital priorities include attracting, retaining and developing high performing talent through its talent management activities. CenterPoint Energy endeavors to maintain a workforce reflective of the available workforce in the United States by attracting quality candidates through its recruitment and selection processes, with the goal of creating a work environment in which every employee is engaged, aligned with CenterPoint Energy’s vision and values and understands how they contribute to its long-term performance. CenterPoint Energy recruits qualified employees regardless of race, gender, color, sexual orientation, age, religion, or physical or mental disability. The talent acquisition team partners with professional organizations and local communities to increase the diversity of new hires which include, Historically Black Colleges and Universities and Hispanic Serving Institutions.

CenterPoint Energy takes a strategic approach to attracting, retaining, and developing its workforce. CenterPoint Energy’s strategy combines talent review and succession planning along with internal talent development as essential elements of overall workforce planning. To support its commitment to safely and reliably delivering electricity and natural gas, CenterPoint Energy focuses on the continuous development of its greatest assets, its employees, building a sustainable leadership pipeline. CenterPoint Energy conducts annual talent review and succession planning with all levels of leadership to ensure business continuity and identify its future leaders. With regards to the senior executive team, the Board of Directors, in conjunction with management, is executing on a comprehensive executive succession planning process, which, among other things, is intended to identify and retain senior executive talent and provide development opportunities. CenterPoint Energy invests in employee development throughout the year to align performance to business needs, drive development planning and contribute to career progression. CenterPoint Energy offers development programs for its employees at all phases of their career including technical and leadership pathways. CenterPoint Energy’s processes and progress are reviewed annually for the purposes of continuous improvement.

Diversity, Equity and Inclusion. CenterPoint Energy is dedicated to advancing an inclusive culture and work environment, free from discrimination of any kind, where business results are achieved through the skills, abilities and talents of a diverse workforce. In 2021, CenterPoint Energy’s Diversity, Equity and Inclusion Council led the approval of the establishment of employee resource groups, ERGs, which stemmed directly from an internal employee diversity survey. These groups focus on employee professional development, networking, cultural awareness and serve as a resource in alignment with CenterPoint



Energy’s goals and objectives. The ERGs encompass groups including, but not limited to, Women, Black, LGBTQ+, Military, Hispanic/Latin, and employees of Indian descent. Each ERG group is sponsored and supported by executive leadership. In an effort of continuous improvement, strategy development and measuring progress, the Diversity, Equity and Inclusion Council participated in surveys to gauge and assess progress in Global Diversity Inclusion Benchmarks. Competitive placements in 2021 were 46% racially and/or ethnically diverse and 30% gender diverse. Additional favorable metrics include the diversity of interview panels and diverse candidates interviewed. As of December 31, 2021, CenterPoint Energy’s workforce was 36% racially and/or ethnically diverse.

Compensation and Benefits. CenterPoint Energy is committed to providing market-competitive pay and benefits. Its compensation philosophy is to maintain employee total compensation that is competitive with the relevant markets, internally equitable and based on CenterPoint Energy’s and the employee’s individual performance. CenterPoint Energy believes such pay practices attract, motivate and retain employees with the skills and competencies necessary to achieve business strategy. To supplement its competitive base compensation, additional programs include short-term and long-term incentive plans, retirement and savings plans, including company matching, healthcare and insurance benefits, disability coverage, paid time off, family leave, employee assistance programs, among other benefits which CenterPoint Energy believes provides a competitive and attractive total rewards package.

Workforce Health and Safety. CenterPoint Energy is committed to the health and safety of its employees, customers, business counterparties and the communities where it operates. Under its Safety Forward approach, safety is the responsibility of all employees. CenterPoint Energy has established a structured employee safety onboarding and development plan through its learning and development platform, offering safety and technical training courses focused on driving, worker safety and safety culture as well as other safety programs designed to encourage employee engagement and participation. Key safety metrics include advanced safety participation, leadership safety engagement rate, days away, restricted or transferred and preventable vehicle incident rate, among other metrics. CenterPoint Energy is aligned with the Edison Electric Institute, American Gas Association and other industry organizations to reduce serious injuries and fatalities. CenterPoint Energy believes the introduction of its READY program adds increased focus on hazard identification and implementation of direct controls to add capacity for safety. In response to the COVID-19 pandemic as a critical service provider, CenterPoint Energy implemented precautionary measures to keep its employees who operate its business safe and informed.

## Item 1A. Risk Factors

CenterPoint Energy is a holding company that conducts all of its business operations through subsidiaries, primarily Houston Electric, CERC, SIGECO, Indiana Gas and VEDO. The following, along with any additional legal proceedings identified or incorporated by reference in Item 3 of this combined report on Form 10-K, summarizes the principal risk factors associated with the holding company and the businesses conducted by its subsidiaries. However, additional risks and uncertainties either not presently known or not currently believed by management to be material may also adversely affect CenterPoint Energy’s businesses. For other factors that may cause actual results to differ from those indicated in any forward-



looking statement or projection contained in this combined report on Form 10-K, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Certain Factors Affecting Future Earnings” in Item 7, which should be read in conjunction with the risk factors contained in this Item 1A. Carefully consider each of the risks described below, including those relating to Houston Electric and CERC, which, along with CenterPoint Energy, are collectively referred to as the Registrants. Unless the context indicates otherwise, where appropriate, information relating to a specific registrant has been segregated and labeled as such and specific references to Houston Electric and CERC in this section also pertain to CenterPoint Energy. In this combined report on Form 10-K, the terms “our,” “we” and “us” are used as abbreviated references to CenterPoint Energy, Inc. together with its subsidiaries.

## Risk Factors Associated with Our Consolidated Financial Condition

CenterPoint Energy is a holding company that derives all of its operating income from, and holds substantially all of its assets through, its subsidiaries. As a result, CenterPoint Energy depends on the performance of and distributions from its subsidiaries to meet its payment obligations and to pay dividends on its common and preferred stock, and provisions of applicable law or contractual restrictions could limit the amount of those distributions.

CenterPoint Energy derives all of its operating income from, and holds substantially all of its assets through, its subsidiaries. As a result, CenterPoint Energy depends on the performance of and distributions from its subsidiaries to meet its payment obligations and to pay dividends on its common and preferred stock. In general, CenterPoint Energy’s subsidiaries are separate and distinct legal entities and have no obligation to provide it with funds for its payment obligations, whether by dividends, distributions, loans or otherwise. In addition, provisions of applicable law, such as those limiting the legal sources of dividends, limit CenterPoint Energy’s subsidiaries’ ability to make payments or other distributions to CenterPoint Energy, and its subsidiaries could agree to contractual restrictions on their ability to make payments or other distributions. Further, Houston Electric has agreed to certain “ring-fencing” measures to increase its financial separateness from CenterPoint Energy. Further ring-fencing measures could be imposed on Houston Electric in the future through legislation or PUCT rules or orders. While current ring-fencing measures have not impacted Houston Electric’s ability to pay dividends to CenterPoint Energy, the imposition of any additional measures impacting CenterPoint Energy’s ability to receive dividends from Houston Electric could materially adversely affect CenterPoint Energy’s cash flows, credit quality, financial condition and results of operations.

CenterPoint Energy’s right to receive assets of any subsidiary, and therefore the right of its creditors to participate in those assets, are structurally subordinated to the claims of that subsidiary’s creditors, including trade creditors. In addition, even if CenterPoint Energy were a creditor of any subsidiary, its rights as a creditor would likely be effectively subordinated to any security interest in the assets of that subsidiary and any senior indebtedness of the subsidiary.

If we are unable to arrange future financings on acceptable terms, our ability to finance our capital expenditures or refinance outstanding indebtedness could be limited.

Our businesses are capital intensive, and we rely on various sources to finance our capital expenditures. For example, we depend on (i) long-term debt, (ii) borrowings through our revolving credit facilities and, for CenterPoint Energy and CERC, commercial paper programs and (iii) if market conditions permit, issuances of additional shares of common or preferred stock by CenterPoint Energy. We may also use such sources to refinance any outstanding indebtedness as it matures. As of December 31, 2021, CenterPoint Energy had $16 billion of outstanding indebtedness on a consolidated basis, which includes $537 million of non-recourse Securitization Bonds. For information on outstanding indebtedness of Houston Electric and CERC as well as future maturities, see Note 14 to the consolidated financial statements. Our future financing activities may be significantly affected by, among other things:

• general economic and capital market conditions, including inflation;

• credit availability from financial institutions and other lenders;

• investor confidence in us and the markets in which we operate;

• the future performance of our businesses;

• maintenance of acceptable credit ratings;

• unanticipated actions from the Federal Reserve;

• market expectations regarding our future earnings and cash flows;

• investor willingness to invest in companies associated with fossil fuels;

• our ability to access capital markets on reasonable terms;

• incremental collateral that may be required due to regulation of derivatives; and

• provisions of relevant securities laws.



The Registrants’ current credit ratings and any changes in credit ratings in 2021 and to date in 2022 are discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Other Matters — Impact on Liquidity of a Downgrade in Credit Ratings” in Item 7 of Part II of this report. These credit ratings may not remain in effect for any given period of time and one or more of these ratings may be reduced or withdrawn by a rating agency. The Registrants note that these credit ratings are not recommendations to buy, sell or hold their securities. Each rating should be evaluated independently of any other rating. Any future reduction or withdrawal of one or more of the Registrants’ credit ratings could have a material adverse impact on their ability to access capital on acceptable terms.

An impairment of goodwill, long-lived assets, including intangible assets, equity method investments and an impairment or fair value adjustment could reduce our earnings.

Long-lived assets, including intangible assets with finite useful lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Goodwill is tested for impairment at least annually, as well as when events or changes in circumstances indicate that the carrying value may not be recoverable. During the year ended December 31, 2020, CenterPoint Energy identified and recorded a goodwill impairment charge of $185 million in the Indiana Electric reporting unit. No impairments to goodwill were recorded during the year ended December 31, 2021. See Note 6 to the consolidated financial statements for further information. Should the annual goodwill impairment test or another periodic impairment test or an observable transaction indicate the fair value of our assets is less than the carrying value, we would be required to take a non-cash charge to earnings with a correlative effect on equity, increasing balance sheet leverage as measured by debt to total capitalization. A non-cash impairment charge or fair value adjustment could materially adversely impact our financial condition and results of operations.

If CenterPoint Energy redeems the ZENS prior to their maturity in 2029, its ultimate tax liability and redemption payments would result in significant cash payments, which would adversely impact its cash flows. Similarly, a significant amount of exchanges of ZENS by ZENS holders could adversely impact CenterPoint Energy’s cash flows.

CenterPoint Energy has approximately $828 million principal amount of ZENS outstanding as of December 31, 2021. CenterPoint Energy owns shares of ZENS-Related Securities equal to approximately 100% of the reference shares used to calculate its obligation to the holders of the ZENS. CenterPoint Energy may redeem all of the ZENS at any time at a redemption amount per ZENS equal to the higher of the contingent principal amount per ZENS ($38 million in the aggregate, or $2.65 per ZENS, as of December 31, 2021) or the sum of the current market value of the reference shares attributable to one ZENS at the time of redemption. In the event CenterPoint Energy redeems the ZENS, in addition to the redemption amount, it would be required to pay deferred taxes related to the ZENS. CenterPoint Energy’s ultimate tax liability related to the ZENS and ZENS-Related Securities continues to increase by the amount of the tax benefit realized each year. If the ZENS had been redeemed on December 31, 2021, deferred taxes of approximately $539 million would have been payable in 2021, based on 2021 tax rates in effect. In addition, if all the shares of ZENS-Related Securities had been sold on December 31, 2021 to fund the aggregate redemption amount, capital gains taxes of approximately $146 million would have been payable in 2021. Similarly, a significant amount of exchanges of ZENS by ZENS holders could adversely impact CenterPoint Energy’s cash flows. This could happen if CenterPoint Energy’s creditworthiness were to drop or the market for the ZENS were to become illiquid, or for some other reason. While funds for the payment of cash upon exchange of ZENS could be obtained from the sale of the shares of ZENS-Related Securities that CenterPoint Energy owns or from other sources, ZENS exchanges result in a cash outflow because tax deferrals related to the ZENS and ZENS-Related Securities shares would typically be disposed when ZENS are exchanged and ZENS-Related Securities shares are sold.

Dividend requirements associated with CenterPoint Energy’s Series A Preferred Stock subject it to certain risks.

CenterPoint Energy has 800,000 shares of Series A Preferred Stock outstanding. Any future payments of cash dividends, and the amount of any cash dividends CenterPoint Energy pays, on its Series A Preferred Stock will depend on, among other things, its financial condition, capital requirements and results of operations and the ability of our subsidiaries to distribute cash to CenterPoint Energy, as well as other factors that CenterPoint Energy’s Board of Directors (or an authorized committee thereof) may consider relevant. Any failure to pay scheduled dividends on the Series A Preferred Stock when due could materially adversely impact our ability to access capital on acceptable terms and would likely have a material adverse impact on the market price of the Series A Preferred Stock, Common Stock and CenterPoint Energy’s debt securities and would prohibit CenterPoint Energy, under the terms of the Series A Preferred Stock, from paying cash dividends on or repurchasing shares of Common Stock (subject to limited exceptions) until such time as CenterPoint Energy has paid all accumulated and unpaid dividends on the Series A Preferred Stock.

Further, the terms of the Series A Preferred Stock provide that if dividends on any of the respective shares have not been declared and paid for the equivalent of three or more semi-annual or six or more quarterly dividend periods, whether or not for



consecutive dividend periods, the holders of such shares, voting together as a single class with holders of any and all other series of CenterPoint Energy’s capital stock on parity with its Series A Preferred Stock (as to the payment of dividends and amounts payable on liquidation, dissolution or winding up of CenterPoint Energy’s affairs) upon which like voting rights have been conferred and are exercisable, will be entitled to vote for the election of a total of two additional members of CenterPoint Energy’s Board of Directors, subject to certain terms and limitations.

Changes in the method of determining LIBOR, or the replacement of LIBOR with an alternative reference rate, may adversely affect the cost of capital related to outstanding debt and other financial instruments.

LIBOR is currently the basic rate of interest widely used as a global reference for setting interest rates on variable rate loans and other securities. Each of the Registrants' credit and term loan facilities, including certain facilities or financial instruments entered into by their subsidiaries, use LIBOR as a reference rate. The Financial Conduct Authority in the United Kingdom previously announced that it would phase out LIBOR as a benchmark by 2021, but later expressed support for the extension of certain tenors of U.S. dollar LIBOR until June 2023, as well as the replacement of LIBOR by the SOFR. Accordingly, beginning January 1, 2022, the Financial Conduct Authority ceased publishing one week and two-month U.S. dollar LIBOR and is expected to cease publishing all remaining U.S. dollar LIBOR tenors in June 2023. The Federal Reserve has also advised banks to cease entering into new contracts that use U.S. dollar LIBOR as a reference rate.

Because SOFR is a broad U.S. Treasury repo financing rate that represents overnight secured funding transactions, it differs fundamentally from LIBOR. Any changes in the methods by which LIBOR is determined or regulatory activity related to LIBOR's phaseout could cause LIBOR to perform differently than in the past or cease to exist. Changes in the method of calculating LIBOR, or the replacement of LIBOR with an alternative rate or benchmark such as SOFR, may adversely affect interest rates and result in higher borrowing costs. This could materially and adversely affect our results of operations, cash flow and liquidity. Each of the Registrants' credit facilities provide for a mechanism to replace LIBOR with possible alternative benchmarks upon certain benchmark replacement events. We are still currently evaluating the impact of any such potential benchmark replacements or unavailability of LIBOR. Also, the overall financial markets may be disrupted as a result of the phase-out or replacement of LIBOR. Uncertainty as to such potential phase-out and alternative benchmark rates or disruption in the financial markets could materially and adversely affect our financial condition, results of operations and cash flows.

Risk Factors Affecting Electric Generation, Transmission and Distribution Businesses (CenterPoint Energy and Houston Electric)

Rate regulation of Houston Electric’s and Indiana Electric’s businesses may delay or deny their ability to earn an expected return and fully recover their costs.

Houston Electric’s rates are regulated by certain municipalities and the PUCT and Indiana Electric’s rates are regulated by the IURC. Their rates are set in comprehensive base rate proceedings (i.e., general rate cases) based on an analysis of their invested capital, their expenses and other factors in a designated test year (often either fully or partially historic). Each of these rate proceedings is subject to third-party intervention and appeal, and the timing of a general base rate proceeding may be out of Houston Electric’s and Indiana Electric’s control. For Houston Electric, a general base rate proceeding is required 48 months from the date of the order setting rates in its most recent comprehensive rate proceeding, unless the PUCT issues an order extending the deadline to file that general base rate proceeding. For Indiana Electric, a general base rate proceeding is required prior to the expiration of its TDSIC plan, which expires on December 31, 2023. Houston Electric and Indiana Electric can make no assurance that their respective base rate proceedings will result in favorable adjustments to their rates, in full cost recovery or approval of other requested items, including, among other things, capital structure and ROE. Moreover, these base rate proceedings have caused in certain instances, and in the future could cause, Houston Electric and Indiana Electric to recover their investments below their requested levels (such as in the most recent Houston Electric general rate case), below the national average for utilities or below recently approved levels for other utilities in their respective jurisdictions.

The rates that Houston Electric and Indiana Electric are allowed to charge may not match their costs at any given time, a situation referred to as “regulatory lag.” For Houston Electric and Indiana Electric, several interim rate adjustment mechanisms have been implemented to reduce the effects of regulatory lag (for example, DCRF, TCOS, TDSIC, DSMA and RCRA Mechanism), although certain of these mechanisms do not provide for recovery of operations and maintenance expenses. These adjustment mechanisms are subject to the applicable regulatory body’s approval and are subject to limitations that may reduce Houston Electric’s and Indiana Electric’s ability to adjust rates. For further information on rate case proceedings and interim rate adjustment mechanisms, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters” in Item 7 of Part II of this report. See also “—The February 2021 Winter Storm...” below for further information.



Houston Electric and Indiana Electric can make no assurance that filings for such mechanisms will result in favorable adjustments to rates or in full cost recovery. Notwithstanding the application of such rate adjustment mechanisms, the regulatory process by which rates are determined is subject to change as a result of the legislative process or rulemaking, as the case may be, and may not always be available or result in rates that will produce recovery of Houston Electric’s and Indiana Electric’s costs or enable them to earn their authorized return. Changes to the interim adjustment mechanisms could result in an increase in regulatory lag or otherwise impact Houston Electric’s and Indiana Electric’s ability to recover their costs in a timely manner. Additionally, inherent in the regulatory process is some level of risk that jurisdictional regulatory authorities may initiate investigations of the prudence of operating expenses incurred or capital investments made by Houston Electric or Indiana Electric and deny the full recovery of their cost of service in rates. To the extent the regulatory process does not allow Houston Electric and Indiana Electric to make a full and timely recovery of appropriate costs, their financial condition, results of operations and cash flows could be materially adversely affected.

Disruptions at power generation facilities owned by third parties or Indiana Electric or directives issued by regulatory authorities could cause interruptions in Houston Electric’s and Indiana Electric’s ability to provide transmission and distribution services and adversely affect their reputation, financial condition, results of operations and cash flows.

Houston Electric owns the transmission and distribution infrastructure that delivers electric power to its customers, but it does not own or operate any power generation facilities. As allowed by a new law enacted by the Texas legislature after the February 2021 Winter Storm Event, Houston Electric is now leasing mobile generation units that can provide temporary emergency electric energy and aid in restoring power to some customers during certain widespread power outages that are impacting its distribution system. In February 2021, the ERCOT regulated Texas electric system experienced extreme winter weather conditions and an unprecedented power generation shortage. The amount of electricity generated by the state’s power generation companies was insufficient to meet the amount demanded by customers. This resulted in ERCOT directing TDUs to significantly Load Shed, which caused outages across the ERCOT electric grid of Texas, including in Houston Electric’s service territory. See Note 7 to the consolidated financial statements for further information. If power generation capacity is severely disrupted again or is inadequate for any reason, or if ERCOT needs to issue directives to TDUs (such as Houston Electric) to Load Shed, Houston Electric’s transmission and distribution services may be diminished or interrupted; it could have claims and litigation filed against it; and its reputation, financial condition, results of operations and cash flows could be adversely affected. For more information, see “— Houston Electric’s use of temporary ...” and “— The February 2021 Winter Storm ...”

Similarly, while Indiana Electric generates power, it is also party to a number of PPAs with third parties. Indiana Electric’s power generation may be disrupted or otherwise insufficient, if third parties do not deliver required power under our PPAs, power generation capacity is inadequate or MISO issues directives to its members (such as Indiana Electric) to implement controlled outages as a result of an emergency or due to reliability issues. If such disruptions were to occur, Indiana Electric’s transmission and distribution services may be diminished or interrupted; it could have claims and litigation filed against it; and its reputation, financial condition, results of operations and cash flows could be adversely affected.

Additionally, Indiana Electric’s generating facilities are subject to operational risks that could result in unscheduled plant outages, unanticipated operation and maintenance expenses, increased purchase power costs and inadvertent releases of coal ash and/or other contaminants with a significant environmental impact. These operational risks can arise from circumstances such as facility shutdowns or malfunctions due to equipment failure or operator error; interruption of fuel supply or increased prices of fuel as contracts expire; disruptions in the delivery of electricity; inability to comply with regulatory or permit requirements; labor disputes; or natural disasters, all of which could adversely affect Indiana Electric’s business. Further, Indiana Electric currently relies on coal for substantially all of its generation capacity. Currently, Indiana Electric purchases substantially all of its coal supply from a single, unrelated party and, although the coal supply is under long-term contract, the loss of this supplier or transportation interruptions could adversely affect Indiana Electric’s financial condition, results of operations and cash flows. In 2021, Indiana Electric experienced coal supply shortages due to labor shortages that the coal industry is experiencing. While the coal supply shortage that Indiana Electric experienced did not impact its ability to deliver electricity to its customers, labor shortages as well as supply shortages in the future, whether caused by insufficient supply or supplier bankruptcy or other regulatory and supply issues in the mining industry, may lead to increased cost and have a material adverse impact on our operations, which could have a material adverse effect on our financial condition, results of operations and cash flows. See “— Continued disruptions to the supply...”

Houston Electric’s receivables are primarily concentrated in a small number of REPs, and any delay or default in such payments could adversely affect Houston Electric’s financial condition, results of operations and cash flows.

Houston Electric’s receivables from the distribution of electricity are collected from REPs that supply the electricity. As of December 31, 2021, Houston Electric provided electric delivery service to approximately 59 REPs. Adverse economic



conditions, such as the impact of COVID-19, the February 2021 Winter Storm Event, structural problems in the market served by ERCOT, inflation or financial difficulties of one or more REPs could impair the ability of these REPs to pay for Houston Electric's services or could cause them to delay such payments. Houston Electric depends on these REPs to remit payments on a timely basis. Houston Electric's PUCT-approved tariff outlines the remedies available to Houston Electric in the event that a REP defaults on amounts owed. Among the remedies available to Houston Electric are seeking recourse against any cash deposit, letter of credit, or surety bond provided by the REP or implementing mutually agreeable terms with the REP. Another remedy is to require that customers be shifted to another REP or a provider of last resort. Houston Electric thus remains at risk for payments related to services provided prior to the shift to another REP or the provider of last resort. A significant portion of Houston Electric's billed receivables from REPs are from affiliates of NRG and Vistra Energy Corp. Houston Electric's aggregate billed receivables balance from REPs as of December 31, 2021 was $207 million. Approximately 40% and 18% of this amount was owed by affiliates of NRG and Vistra Energy Corp., respectively. Any delay or default in payment by REPs could adversely affect Houston Electric's financial condition, results of operations and cash flows. If a REP was unable to meet its obligations, it could consider, among various options, restructuring under the bankruptcy laws, in which event such REP might seek to avoid honoring its obligations, and claims might be made regarding prior payments Houston Electric had received from such REP. For example, following the February 2021 Winter Storm Event, multiple REPs filed for bankruptcy. We are currently capturing the amounts owed by the REPs as a permitted regulatory asset for bad debt expenses, which will be subject to a reasonableness review by the PUCT when we seek recovery in our next base rate case.

Indiana Electric’s execution of its generation transition plan, including its IRP, are subject to various risks, including timely recovery of capital investments and increased costs and risks related to the timing and cost of development and/or construction of new generation facilities.

Indiana requires each electric utility to perform and submit an IRP every three years, unless extended, to the IURC that uses economic modeling to consider the costs and risks associated with available resource options to provide reliable electric service for the next 20-year period on a periodic basis. In February 2018, as part of its electric generation transition plan, Indiana Electric received approval from the IURC to construct a 50 MW universal solar array and a plan to retrofit its largest, most efficient coal-fired generation unit (Culley Unit 3). With respect to its 2019/2020 IRP submitted to the IURC in June 2020, Indiana Electric identified a preferred generation resource that includes the replacement of 730 MW of coal-fired generation facilities with a significant portion composed of renewables, including solar and wind, supported by dispatchable natural gas combustion turbines, including a pipeline to serve such natural gas generation, as well as storage. While the IURC does not approve or reject the IRP, the process involves the issuance of a staff report that provides comments on the IRP. On November 17, 2021, Indiana Electric received the staff report on the IRP. Further, there is no guarantee that the IURC will approve the requests included in any of Indiana Electric’s future filed petitions relating to its IRP.

Even if a generation project is approved, risks associated with the development or construction of any new generation exist, including new legislation restricting or delaying new generation, moratorium legislation, the ability to procure resources needed to build at a reasonable cost, scarcity of resources and labor, ability to appropriately estimate costs of new generation, the effects of potential construction delays, project scope changes, and cost overruns and the ability to meet capacity requirements. For example, we, along with our developers of the Posey solar project, have recently announced plans to downsize the Posey solar project from 300 MW to 200 MW due to supply chain issues experienced in the energy industry, the rising cost of commodities and community feedback. For additional information, see “— Continued disruptions to the supply...” Furthermore, we have announced our intent to acquire and/or develop additional solar and wind facilities as part of our capital plan. However, we have not yet entered into definitive agreements with developers for the acquisition and/or development of such additional projects, and we face significant competition with other bidders for a limited number of such generation facilities that developers plan to construct, including those that are in an acceptable position on the MISO interconnection queue. As a result, suitable generation facility project candidates may not be available on terms and conditions we find acceptable, or the expected benefits of a completed facility may not be realized fully or at all, or may not be realized in the anticipated timeframe. If we are unable to complete or acquire such generation facilities, or if they do not perform as anticipated, our future growth, financial condition, results of operations and cash flows may be adversely affected.

Houston Electric and Indiana Electric, as a member of ERCOT and MISO, respectively, could be subject to higher costs for system improvements, as well as fines or other sanctions as a result of FERC mandatory reliability standards.

Houston Electric and Indiana Electric are members of ERCOT and MISO, respectively, which serve the electric transmission needs of their applicable regions. As a result of their respective participation in ERCOT and MISO, Houston Electric and Indiana Electric do not have operational control over their transmission facilities and are subject to certain costs for improvements to these regional electric transmission systems. In addition, the FERC has jurisdiction with respect to ensuring the reliability of electric transmission service, including transmission facilities owned by Houston Electric and other utilities within ERCOT and Indiana Electric and other utilities within MISO, respectively. The FERC has designated the NERC as the



ERO to promulgate standards, under FERC oversight, for all owners, operators and users of the bulk power system. The FERC has approved the delegation by the NERC of authority for reliability in ERCOT to the Texas RE, a Texas non-profit corporation and for reliability in the portion of MISO that includes Indiana Electric to ReliabilityFirst Corporation, a Delaware non-profit corporation. Compliance with mandatory reliability standards may subject Houston Electric and Indiana Electric to higher operating costs and may result in increased capital expenditures, which may not be fully recoverable in rates. While Houston Electric and Indiana Electric have received minor fines in the past for noncompliance, if Houston Electric or Indiana Electric were to be found to be in noncompliance with applicable mandatory reliability standards again, they would be subject to sanctions, including substantial monetary penalties, which could range as high as over a million dollars per violation per day, and non-monetary penalties, such as having to file a mitigation plan to prevent recurrence of a similar violation and having certain milestones in such plan tracked.

In connection with the February 2021 Winter Storm Event, there have been calls for reform of the Texas electric market, some measure of which, if implemented, could have material adverse impacts on Houston Electric.

Various governmental and regulatory agencies and other entities have called for or are conducting inquiries and investigations into the February 2021 Winter Storm Event and the efforts made by various entities to prepare for, and respond to, this event, including the electricity generation shortfall issues. Such agencies and entities include the United States Congress, FERC, NERC, Texas RE, ERCOT, Texas government entities and officials such as the Texas Governor's office, the Texas Legislature, the Texas Attorney General, the PUCT, the City of Houston and other municipal and county entities in Houston Electric's service area, among other entities. In addition to questions around preparation and response, some federal and other officials, as well as members of the public and media, have called for reviews and reforms of the Texas electric market, including whether it should continue to be governed by ERCOT or instead be subject to FERC jurisdiction and regulation by joining an ISO such as MISO, as well as the division of the market between power generators, TDUs (such as Houston Electric) and REPs. There are significant uncertainties around these discussions and whether any market structure or governance changes will result therefrom, but if any such reviews and reform efforts ultimately result in changes to how the Texas electric market is structured or regulated, such changes could have a material adverse impact on Houston Electric's business, financial condition and results of operations. See “—The February 2021 Winter Storm...” below and Note 7 to the consolidated financial statements for further information.

Houston Electric’s use of temporary mobile generation resources is subject to various risks, including related failure to obtain and deploy sufficient mobile generation units, potential performance issues and allegations about Houston Electric’s deployment of the resources (including the planning, execution, and effectiveness of the same), regulatory and environmental requirements, and timely recovery of capital.

Following the February 2021 Winter Storm Event, the Texas legislature passed a new law, effective September 1, 2021, that allows TDUs, like Houston Electric, to lease and operate temporary back-up generation resources during widespread power outages where ERCOT has ordered a TDU to shed load or the TDU’s distribution facilities are not being fully served by the bulk power system under normal operations. In response to this legislation, Houston Electric has entered into short-term and long-term leases with a third party provider to obtain mobile generation units.

However, if Houston Electric is otherwise unable to deploy a sufficient number of mobile generation units in time to respond to a particular event; if the mobile generation units fail to perform as intended; if Houston Electric is otherwise unable to provide back-up generation resources and restore power as intended; or if the use of mobile generation units or their failure to perform causes or is alleged to cause any personal injury, property damage, or other damage or loss due to allegations that it failed to deploy such units reasonably or effectively and failed to respond to particular power outages, Houston Electric could be subject to claims, demands, litigation, liability, regulatory scrutiny, and loss of reputation. As noted above, the legislation prescribes specific and limited use for the mobile generation units, and Houston Electric’s mobile generation units have limited generation capacity, such that in future events customers could still be without power despite deployment of the mobile units.

While Houston Electric has insurance coverage and indemnity rights for its use of mobile generation units, if its insurers or indemnitors fail to meet their indemnity obligations, Houston Electric could be liable for personal injury, property damage, or other damage or loss. Further, the mobile generation units are subject to various environmental regulations and permitting requirements, which could have an impact on Houston Electric’s ability to use these units, and noncompliance with which could subject Houston Electric to further potential liability. The use of mobile generation units is also subject to various requirements of the new legislation, and failure to comply with them could subject Houston Electric to additional liability as well as challenges to its use of mobile generation in general. While Houston Electric will seek to recover the costs of the lease and use of mobile generation units, such recovery is not certain, and Houston Electric’s inability to recover its costs could have a material adverse impact on its financial condition, results of operations and cash flows. For further information, see “— Rate Regulation of Houston Electric’s...”, “— Our insurance coverage may not...” and “— We are subject to operational...”



## Risk Factors Affecting Natural Gas’ Business (CenterPoint Energy and CERC)

## Rate regulation of Natural Gas may delay or deny its ability to earn an expected return and fully recover its costs.

Natural Gas’ rates are regulated by certain municipalities (in Texas only) and state commissions based on an analysis of Natural Gas’ invested capital, expenses and other factors in a test year (often either fully or partially historic) in comprehensive base rate proceedings, subject to periodic review and adjustment. Each of these proceedings is subject to third-party intervention and appeal, and the timing of a general base rate proceeding may be out of Natural Gas’ control. During 2022, Natural Gas has a pending rate case and a proceeding considering recovery of extraordinary natural gas costs during the February 2021 Winter Storm Event in Minnesota. In the Minnesota extraordinary natural gas cost proceeding, various parties have proposed significant disallowances for all natural gas utilities ranging from $45 million to $409 million for CenterPoint Energy and CERC. Natural Gas can make no assurance that these respective base rate and cost recovery proceedings will result in favorable adjustments to its rates, full or adequate cost recovery or approval of other requested items, including, among other things, capital structure and ROE. These base rate proceedings could cause Natural Gas to recover its investments at rates below its requested level, the national average for utilities or recently approved levels for other utilities in those jurisdictions.

The rates that Natural Gas is allowed to charge may not match its costs at any given time, resulting in what is referred to as “regulatory lag.” For example, the MPUC has ordered that the amortization period for extraordinary gas costs resulting from the February 2021 Winter Storm Event be increased from 27-months to 63-months beginning on January 1, 2022, and that CERC forego recovery of the associated carrying costs. Though several interim rate adjustment mechanisms have been approved by jurisdictional regulatory authorities and implemented by Natural Gas to reduce the effects of regulatory lag (for example, CSIA, DRR, GRIP, RRA and RSP), such adjustment mechanisms are subject to the applicable regulatory body’s approval, which we cannot assure would be approved, and are subject to certain limitations that may reduce or otherwise impede Natural Gas’ ability to adjust its rates or result in rates below those requested by Natural Gas.

Natural Gas can make no assurance that filings for such mechanisms will result in favorable adjustments to rates. Notwithstanding the application of the rate mechanisms discussed above, the regulatory process by which rates are determined is subject to change as a result of the legislative process or rulemaking, as the case may be, and may not always be available or result in rates that will produce recovery of Natural Gas’ costs or enable Natural Gas to earn an expected return. Changes to the interim adjustment mechanisms could result in an increase in regulatory lag or otherwise impact Natural Gas’ ability to recover its costs in a timely manner. Additionally, inherent in the regulatory process is some level of risk that jurisdictional regulatory authorities may initiate investigations of the prudence of operating expenses incurred or capital investments made by Natural Gas and deny the full recovery of Natural Gas’ cost of service or the full recovery of incurred natural gas costs in rates. To the extent the regulatory process does not allow Natural Gas to make a full and timely recovery of appropriate costs, its financial condition, results of operations and cash flows could be adversely affected. For further information on rate case proceedings and interim rate adjustment mechanisms, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Regulatory Matters” in Item 7 of Part II of this report.

Unlike CERC, Indiana Gas, SIGECO’s natural gas distribution business and VEDO must seek approval by the IURC and PUCO, as applicable, for long-term financing authority. This authority allows these utilities the flexibility to enter into various financing arrangements. In the event that the IURC or PUCO do not approve these utilities’ respective financing authorities, they may not be able to fully execute their financing plans and their respective financial conditions, results of operations and cash flows could be adversely affected. For more information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Regulatory Matters.”

Access to natural gas supplies and pipeline transmission and storage capacity are essential components of reliable service for Natural Gas’ customers.

Natural Gas depends on third-party service providers to maintain an adequate supply of natural gas and for available storage and intrastate and interstate pipeline capacity to satisfy its customers' needs, all of which are critical to system reliability. Substantially all of Natural Gas' natural gas supply is purchased from intrastate and interstate pipelines. If Natural Gas is unable to secure an independent natural gas supply of its own or through its affiliates or if third-party service providers fail to timely deliver natural gas to meet Natural Gas' requirements, the resulting decrease in natural gas supply in Natural Gas' service territories could have a material adverse effect on its financial condition, results of operations and cash flows. Additionally, a significant disruption, whether through reduced intrastate and interstate pipeline transmission or storage capacity or other events affecting natural gas supply, including, but not limited to, operational failures, hurricanes, tornadoes, floods, severe winter weather conditions, acts of terrorism or cyberattacks or changes in legislative or regulatory requirements,



could also adversely affect Natural Gas’ businesses. Further, to the extent that Natural Gas’ natural gas requirements cannot be met through access to or continued use of existing natural gas infrastructure or if additional infrastructure, including onshore and offshore exploration and production facilities, gathering and processing systems and pipeline and storage capacity is not constructed at a rate that satisfies demand, then Natural Gas’ operations could be negatively affected. For additional risks related to the February 2021 Winter Storm Event, see “—The February 2021 Winter Storm...” below and Note 7 to the consolidated condensed financial statements for further information.

Natural Gas is subject to fluctuations in notional natural gas prices, which could affect the ability of its suppliers and customers to meet their obligations or may impact our operations which could adversely affect CERC’s financial condition, results of operations and cash flows.

Natural Gas is subject to risk associated with changes in the notional price of natural gas. Increases in natural gas prices might affect Natural Gas' ability to collect balances due from customers and could create the potential for uncollectible accounts expense to exceed the recoverable levels built into tariff rates. In addition, a sustained period of high natural gas prices could (i) decrease demand for natural gas in the areas in which Natural Gas operates, thereby resulting in decreased sales and revenues and (ii) increase the risk that Natural Gas' suppliers or customers fail or are unable to meet their obligations. An increase in natural gas prices would also increase working capital requirements by increasing the investment that must be made to maintain natural gas inventory levels. For additional risks related to the February 2021 Winter Storm Event, see “—The February 2021 Winter Storm...” below and Note 7 to the consolidated condensed financial statements for further information.

A decline in CERC’s credit rating could result in CERC having to provide collateral under its shipping arrangements or to purchase natural gas, which consequently would increase its cash requirements and adversely affect its financial condition.

If CERC’s credit rating were to decline, it might be required to post cash collateral under its shipping arrangements or to purchase natural gas. If a credit rating downgrade and the resultant cash collateral requirement were to occur at a time when CERC was experiencing significant working capital requirements or otherwise lacked liquidity, CERC’s financial condition, results of operations and cash flows could be adversely affected. For additional risks related to the February 2021 Winter Storm Event, see “—The February 2021 Winter Storm...” below and Note 7 to the consolidated condensed financial statements for further information.

Natural Gas must compete with alternate energy sources, which could result in less natural gas delivered and have an adverse impact on CERC’s financial condition, results of operations and cash flows.

Natural Gas competes primarily with alternate energy sources such as electricity and other fuel sources. In some areas, intrastate pipelines, other natural gas distributors and marketers also compete directly with Natural Gas for natural gas sales to end users. In addition, as a result of federal regulatory changes affecting interstate pipelines, natural gas marketers operating on these pipelines may be able to bypass Natural Gas' facilities and market, sell and/or transport natural gas directly to commercial and industrial customers. Any reduction in the amount of natural gas delivered by Natural Gas as a result of competition with alternate energy sources may have an adverse impact on CERC's financial condition, results of operations and cash flows.

Risk Factors Affecting Energy Systems Group’s Business (CenterPoint Energy)

Energy Systems Group’s operations could be adversely affected by a number of factors.

Energy Systems Group’s business results are dependent on a number of factors. The industry in which Energy Systems Group operates is competitive and many of the contracts are subject to a bidding process. Should Energy Systems Group be unsuccessful in bidding contracts (for example, federal Indefinite Delivery/Indefinite Quantity contracts), results of operations could be impacted. Through competitive bidding, the volume of contracted work could vary significantly from year to year. Further, to the extent there are unanticipated cost increases in completion of the contracted work or issues arise where amounts due for work performed may not be collected, the profit margin realized on any single project could be reduced. Changes in legislation and regulations impacting the sectors in which the customers served by Energy Systems Group operate could adversely impact operating results. Additionally, Energy Systems Group’s business is subject to other risks including, but not limited to, the following: the discontinuation of the federal ESPC and UESC programs; the inability of customers to finance projects; failure to appropriately design, construct or operate projects; increased project delays and backlogs, particularly in the federal sector, increases in costs and shortages in supply materials due to the COVID-19 pandemic and other factors; cancellation of projects by customers or reductions in the scope of the projects; and obligations related to warranties, guarantees and other contractual and legal obligations.



Energy Systems Group’s business has performance and warranty obligations, some of which are guaranteed by CenterPoint Energy.

In the normal course of business, Energy Systems Group issues performance bonds and other forms of assurance that commit it to operate facilities, pay vendors or subcontractors and support warranty obligations. As the parent company, CenterPoint Energy or Vectren has, and will, from time to time guarantee its subsidiaries' commitments. These guarantees do not represent incremental consolidated obligations; rather, they represent parental guarantees of subsidiary obligations to allow the subsidiary the flexibility to conduct business without posting other forms of collateral. Neither CenterPoint Energy nor Vectren has been called upon to satisfy any obligations pursuant to these parental guarantees to date.

## Risk Factors Affecting Our Businesses

We are subject to operational and financial risks and liabilities arising from environmental laws and regulations, including regulation of CCR and climate change legislation. We could also experience reduced demand for our services, including certain local initiatives to prohibit new natural gas service and increase electrification initiatives in jurisdictions served by Natural Gas.

Our operations are subject to stringent and complex laws and regulations pertaining to the environment. As an owner or operator of natural gas pipelines, distribution systems and storage, electric generating facilities and electric transmission and distribution systems, and the facilities that support these systems, we must comply with these laws and regulations at the federal, state and local levels. These laws and regulations can restrict or impact our business activities in many ways, including among others, restricting the use of fossil fuels through future climate legislation or regulation, restricting the use of natural gas-fired appliances in new homes, limiting airborne emissions from generating facilities, restricting the way we manage wastes, including wastewater discharges and air emissions and requiring remedial action or monitoring to mitigate environmental actions caused by our operations or attributable to former operations. We may need to spend substantial amounts and devote other resources from time to time to comply with these requirements. Failure to comply with these laws and regulations may trigger a variety of administrative, civil and criminal enforcement measures, including the assessment of monetary penalties, revocation of permits, the imposition of remedial actions, and the issuance of orders enjoining future operations. Certain environmental statutes impose strict joint and several liability for costs required to clean, restore and monitor sites where hazardous substances have been stored, disposed or released. Moreover, it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous substances or other waste products into the environment.

In April 2015, the EPA finalized its CCR Rule, which regulates ash as non-hazardous material under the RCRA. The final rule allows beneficial reuse of ash, and the majority of the ash generated by Indiana Electric’s generating plants will continue to be beneficially reused. In July 2018, the EPA released its final CCR Rule Phase I Reconsideration which extended the deadline to October 31, 2020 for ceasing placement of ash in ponds that exceed groundwater protections standards or that fail to meet location restrictions. In August 2019, the EPA proposed additional “Part A” amendments to its CCR Rule with respect to beneficial reuse of ash and other materials. Further “Part B” amendments, which related to alternate liners for CCR surface impoundments and the surface impoundment closure process, were published in March 2020. The Part A amendments were finalized in August 2020, and the Part B amendments were finalized in November 2020 and extended the deadline to cease placement of ash in ponds to April 11, 2021. The EPA published an advanced notice of proposed rulemaking on legacy CCR surface impoundments in October 2020, and in December 2020 provided new data and requested public comment as part of the Agency’s reconsideration of its definition of beneficial reuse. The Part A amendments do not restrict Indiana Electric’s current beneficial reuse of its fly ash. The potential effects of future amendments to the CCR Rule are uncertain at this time.

Regulatory agencies have also adopted, and from time to time consider adopting, new legislation and/or modifying existing laws and regulations to reduce GHGs. There continues to be a wide-ranging policy and regulatory debate, both nationally and internationally, regarding the potential impact of GHGs and possible means for their regulation. The EPA has expanded its existing GHG emissions reporting requirements, which could also lead to further regulation of GHGs by the EPA. The recent trend in environmental regulation has been to place more restrictions and limitations on activities that may impact the environment, which is expected to continue under the Biden administration. For example, shortly after taking office in January 2021, President Biden issued a series of executive orders designed to address climate change, as well as an executive order requiring agencies to review environmental actions taken by the Trump administration. The Biden administration also issued a memorandum to departments and agencies to refrain from proposing or issuing rules until a departmental or agency head appointed or designated by the Biden administration has reviewed and approved the rule. President Biden also recommitted the United States to the Paris Agreement, which can be expected to drive a renewed regulatory push to require further GHG emission reductions from the energy sector and proceeded to lead negotiations at the global climate conference in Glasgow, Scotland. On April 22, 2021, President Biden announced new goals of 50% reduction of economy-wide GHG emissions and



100% carbon-free electricity by 2035, which formed the basis of the United States' commitments announced in Glasgow. Reentry into the Paris Agreement, revised climate commitments coming out of the 2021 United Nations Climate Change Conference held in Glasgow, Scotland and President Biden's executive orders may result in the development of additional regulations or changes to existing regulations. Potential future restrictions include, among other things, the United States enacting additional GHG regulations and mandated financial, emissions and other disclosures. As a distributor and transporter of natural gas, Natural Gas' revenues, operating costs and capital requirements could be adversely affected as a result of any regulatory action that would require installation of new control technologies or a modification of its operations or that would have the effect of reducing the consumption of natural gas. Thus, there can be no assurance as to the amount or timing of future expenditures for environmental compliance or remediation, and actual future expenditures may be greater than the amounts we currently anticipate. Likewise, incentives to conserve energy or use energy sources other than natural gas could result in a decrease in demand for our services. For further discussion, see “Business—Environmental Matters” in Item 1 and “—Natural Gas must compete with...”

Evolving investor sentiment related to the use of fossil fuels and initiatives to restrict continued production of fossil fuels may have substantial impacts on CenterPoint Energy’s electric generation and natural gas businesses. For example, because Indiana Electric’s current generating facilities substantially rely on coal for their operations, certain financial institutions choose not to participate in CenterPoint Energy’s financing arrangements. Further, some investors may choose to not invest in CenterPoint Energy due to CenterPoint Energy’s use of fossil fuels. Also, certain cities in CenterPoint Energy’s Natural Gas operational footprint have adopted initiatives to prohibit the construction of new natural gas facilities that would provide service and focus on electrification. For example, Minneapolis has adopted carbon emission reduction goals in an effort to decrease reliance on fossil gas. Also, Minnesota cities may consider seeking legislative authority for the ability to enact voluntary enhanced energy standards for all development projects. Certain state and local governments in states such as New York and California have also passed, or are considering, legislation banning the use of natural gas-fired appliances in new homes, which could affect consumer use of natural gas. Should such bans be enacted within Natural Gas’ operational footprint, they could adversely affect consumer demand for natural gas. Any such initiatives and legislation could adversely affect CenterPoint Energy’s results of operations.

CenterPoint Energy is subject to operational and financial risks and liabilities associated with the implementation of and efforts to achieve its carbon emission reduction goals.

In September 2021, CenterPoint Energy announced its new net zero emission goals for Scope 1 and 2 emissions by 2035 and a 20-30% reduction in Scope 3 emissions by 2035 as compared to 2021 levels. CenterPoint Energy’s analysis and plan for execution requires it to make a number of assumptions. These goals and underlying assumptions involve risks and uncertainties and are not guarantees. Should one or more of CenterPoint Energy’s underlying assumptions prove incorrect, its actual results and ability to achieve net zero emissions by 2035 could differ materially from its expectations. Certain of the assumptions that could impact CenterPoint Energy’s ability to meet its net zero emissions goals include, but are not limited to: emission levels, service territory size and capacity needs remaining in line with expectations; regulatory approval of Indiana Electric’s generation transition plan; impacts of future environmental regulations or legislation; impact of future carbon pricing regulations or legislation, including a future carbon tax; price, availability and regulation of carbon offsets; price of fuel, such as natural gas; cost of energy generation technologies, such as wind and solar, natural gas and storage solutions; adoption of alternative energy by the public, including adoption of electric vehicles; rate of technology innovation with regards to alternative energy resources; CenterPoint Energy’s ability to implement its modernization plans for its pipelines and facilities; the ability to complete and implement generation alternatives to Indiana Electric’s coal generation and retirement dates of Indiana Electric’s coal facilities by 2035; the ability to construct and/or permit new natural gas pipelines; the ability to procure resources needed to build at a reasonable cost, the lack of or scarcity of resources and labor, any project cancellations, construction delays or overruns and the ability to appropriately estimate costs of new generation; impact of any supply chain disruptions; changes in applicable standards or methodologies; and enhancement of energy efficiencies. Our businesses may face increased scrutiny from investors and other stakeholders related to our sustainability activities, including the goals, targets, and objectives that we announce, and our methodologies and timelines for pursuing them. If our sustainability practices do not meet investor or other stakeholder expectations and standards, which continue to evolve, our reputation, our ability to attract or retain employees, and our attractiveness as an investment or business partner could be negatively affected. Similarly, our failure or perceived failure to pursue or fulfill our sustainability-focused goals, targets, and objectives, to comply with ethical, environmental, or other standards, regulations, or expectations, or to satisfy various reporting standards with respect to these matters, within the timelines we announce, or at all, could adversely affect our business or reputation, as well as expose us to government enforcement actions and private litigation.

Developing and implementing plans for compliance with voluntary climate commitments can lead to additional capital, personnel and operation and maintenance expenditures and could significantly affect the economic position of existing facilities and proposed projects. To the extent that we believe any of these costs are recoverable in rates, cost recovery could be resisted



by our regulators and our regulators might attempt to deny or defer timely recovery of these costs. Moreover, we cannot predict the ultimate impact of achieving our emissions reduction goals, or the various implementation aspects, on our system reliability or our financial condition and results of operations.

Continued disruptions to the global supply chain may lead to higher prices for goods and services and impact our operations, which could have a material adverse impact on our ability to execute our capital plan and on our financial condition, results of operations and cash flows.

The global supply chain has experienced and is expected to continue to experience disruptions due to a multitude of factors, such as the COVID-19 pandemic, labor shortages, resource availability, long lead time, inflation and weather, and these disruptions have adversely impacted the utility industry. We have experienced disruptions to our supply chain, as well as increased prices, and we may continue to experience this in the future. For example, we, along with the developer of the project, recently announced plans to downsize the previously announced solar array to be built in Posey County, Indiana from 300 MW to 200 MW due to supply chain issues experienced in the energy industry, the rising cost of commodities and community feedback. Additionally, we, as well as other companies in our industry, have experienced difficulties in procuring certain materials necessary for the transmission and distribution of power, such as transformers, wires, cables and meters. We may continue to experience difficulties in procuring these resources and others necessary to operate our businesses in the future, and if we were to experience other significant supply chain disruptions in the future, we may not be able to procure the resources, including labor, needed to fully execute on our ten-year capital plan or achieve our net zero emission goals. Even if we are able to procure the necessary resources, we might not be able to do so at a reasonable cost or in a timely manner which could result in project cancellations or scope changes, delays, cost overruns and under-recovery of costs. If we are unable to fully execute on capital plans as a result of supply chain disruptions, our financial condition, results of operations and cash flows may be materially and adversely affected.

The February 2021 Winter Storm Event caused severe disruptions in certain of our jurisdictions and could have a material adverse impact to our financial condition, results of operations, cash flows and liquidity.

In February 2021, certain of our jurisdictions experienced an extreme and unprecedented winter weather event with prolonged freezing temperatures that resulted in an electricity generation shortage in our Houston Electric service area, which impacted our businesses. The electricity generation shortages necessitated ERCOT to direct TDUs, including Houston Electric, to implement controlled outages in their respective service areas. In compliance with ERCOT’s directives and emergency procedures, Houston Electric implemented controlled electricity outages across its service territory, resulting in a substantial number of its customers (on certain days over a million residents) being without power, many for extended periods of time. ERCOT has stated that the electric outages were necessary to avoid prolonged large-scale, state-wide blackouts and long-term damage to the electric system in Texas. As a result, Houston Electric’s sales of transmission and distribution services were diminished or interrupted for several days. Additionally, the electricity generation shortage resulted in wholesale electricity prices increasing to their maximum allowed limit.

During and in the aftermath of the February 2021 Winter Storm Event, the Texas legislature revised applicable statutes and granted the PUCT and ERCOT additional regulatory authority, both oversight and enforcement, that focuses on ensuring that ERCOT market participants, including power generation facilities and TDUs (like Houston Electric), have sufficient winterization standards and protection. Houston Electric is in compliance with the requirements applicable to it. If any additional protections are required in the future, complying with these new protections may increase the cost of electricity and reduce consumption of electricity by ultimate consumers in Houston Electric’s service territory, which could adversely affect Houston Electric’s results of operations. Any potential decreases in customer usage due to higher electricity prices charged by REPs may not result in increased base rates charged by Houston Electric for its services until its next general base rate proceeding.

Furthermore, the February 2021 Winter Storm Event also impacted the wholesale prices CenterPoint Energy and CERC paid for natural gas and their ability to service customers in their Natural Gas service territories, including due to the reduction in available natural gas capacity, impacts to CenterPoint Energy’s and CERC’s natural gas supply portfolio activities, and their ability to transport natural gas, among other things. In particular, the February 2021 Winter Storm Event also caused severe disruptions in the markets from which CenterPoint Energy and CERC sourced a significant portion of their natural gas for their utility operations, resulting in extraordinary increases in the price of natural gas to CenterPoint Energy and CERC. From February 12, 2021 to February 22, 2021, CenterPoint Energy spent approximately an incremental $2.2 billion more on natural gas supplies compared to plan. These amounts are based on final settlements of supplier and pipeline invoices from February 2021, including amounts negotiated to resolve disputes with various suppliers as of January 2022.



In addition to the risks discussed in this risk factor, for further information on risks related to:

• the arranging of future financings on acceptable terms, see “— If we are unable to...”;”

• the ability to receive payment from a REP, see “— Houston Electric’s receivables are primarily...”

• the ability to seek recovery of the additional costs of natural gas, see “— Rate regulation of Natural Gas...”;”

• access to natural gas supplies, see “— Access to natural gas supplies...”;”

• various regulatory, investigations, litigation or other proceedings, see “— In connection with the February...” and Note 16 to the consolidated condensed financial statements;

• the fluctuations in notional natural gas prices, see “— Natural Gas is subject to...”; and

• the impact of a decline in CERC’s credit rating, see “— A decline in CERC’s credit ...”

Our financial condition, results of operations and cash flows may be adversely affected if we are unable to successfully operate our facilities or perform certain corporate functions.

Our performance depends on the successful operation of our facilities. Operating these facilities involves many risks inherent in the generation, transmission and distribution of electricity and in the delivery of natural gas that could result in substantial losses or other damages. These risks include, but are not limited to, the following:

• operator error or failure of equipment or processes, including failure to follow appropriate safety protocols;

- the handling of hazardous equipment or materials that could result in serious personal injury, loss of life and environmental and property damage;

• operating limitations that may be imposed by environmental or other regulatory requirements;

• labor disputes;

- information technology or financial and billing system failures, including those due to the implementation and integration of new technology, that impair our information technology infrastructure, reporting systems or disrupt normal business operations;

- failure to obtain in a timely manner and at reasonable prices the necessary fuel, such as coal and natural gas, building materials or other items needed to operate our facilities;

- information technology failure that affects our ability to access customer information or causes us to lose confidential or proprietary data that materially and adversely affects our reputation or exposes us to legal claims; and

- catastrophic events such as fires, earthquakes, explosions, leaks, floods, droughts, hurricanes, ice storms, flooding, terrorism, wildfires, pandemic health events or other similar occurrences, including any environmental impacts related thereto, which catastrophic events may require participation in mutual assistance efforts by us or other utilities to assist in power restoration efforts.

Such events may result in a decrease or elimination of revenue from our facilities, an increase in the cost of operating our facilities or delays in cash collections, any of which could have a material adverse effect on our financial condition, results of operations and cash flows.

## Our revenues and results of operations are seasonal.

A significant portion of Houston Electric’s revenues is derived from rates that it collects from each REP based on the amount of electricity it delivers on behalf of such REP. Similarly, Indiana Electric’s revenues are derived from rates it charges its customers to provide electricity. Natural Gas’ revenues are primarily derived from natural gas sales. Consequently, Houston Electric’s, Indiana Electric’s and Natural Gas’ revenues and results of operations are subject to seasonality, weather conditions and other changes in electricity and natural gas usage, as applicable. Houston Electric’s revenues are generally higher during the warmer months. As in certain past years, unusually mild weather in the warmer months could diminish Houston Electric’s results of operations and harm its financial condition. Conversely, as in certain past years, extreme warm weather conditions could increase Houston Electric’s results of operations in a manner that would not likely be annually recurring. A significant portion of Indiana Electric’s sales are for space heating and cooling. Consequently, as in certain past years, Indiana Electric’s results of operations may be adversely affected by warmer-than-normal heating season weather or colder-than-normal cooling season weather, while more extreme seasonal weather conditions could increase Indiana Electric’s results of operations in a manner that would not likely be annually recurring. Natural Gas’ revenues are customarily higher during the winter months. As in certain past years, unusually mild weather in the winter months could diminish Natural Gas’ results of operations and harm its financial condition. Conversely, as occurred in certain past years, extreme cold weather conditions could increase its results of operations in a manner that would not likely be annually recurring. For information related to our weather hedges, see Note 9(a) to the consolidated financial statements. For additional risks related to the February 2021 Winter Storm Event, see “—The February 2021 Winter Storm...” below and Note 7 to the consolidated condensed financial statements for further information.



Climate change could adversely impact financial results from our businesses and result in more frequent and more severe weather events that could adversely affect our results of operations.

A changing climate creates uncertainty and could result in broad changes, both physical and financial in nature, to our service territories and our business. If climate changes occur that result in warmer temperatures than normal in our service territories, financial results from our businesses could be adversely impacted. For example, where natural gas is used to heat homes and businesses, warmer weather might result in less natural gas being used, adversely affecting us. Another possible result of climate change is more frequent and more severe weather events, such as hurricanes, tornadoes and severe winter weather conditions, including ice storms, all of which may impact our operations and ability to serve our customers. To the extent the frequency and severity of extreme weather events increases, our costs of providing service may increase, including the costs and availability of procuring insurance related to such impacts, and those costs may not be recoverable. Further, events of extreme weather could make it unsafe or hinder the effectiveness of our employees to fix, maintain and restore power to affected areas and could harm our reputation. Since certain of our facilities are located along or near the Texas gulf coast, increased or more severe hurricanes or tornadoes could increase our costs to repair damaged facilities and restore service to our customers. Our electric and Natural Gas operations in our service territories were both also impacted by the February 2021 Winter Storm Event. In the long term, climate change could also cause shifts in population, including customers moving away from our service territories. When we cannot deliver electricity or natural gas to customers or our customers cannot receive our services, our financial results are impacted by lost revenues, and we generally must seek approval from regulators to recover restoration costs. To the extent we are unable to recover those costs, or if recovery of such costs results in higher rates and reduced demand for our services, our future financial results may be adversely impacted. Any such decreased energy use may also require us to retire current infrastructure that is no longer needed. Similarly, public and private efforts to address climate change, such as by legislation, regulation, actions by private interest groups, and litigation, could impact our ability to continue operating our businesses as we do today, significant aspects of which rely on fossil fuels. These initiatives could have a significant impact on us and our operations as well as on our third party suppliers, vendors and partners, which could impact us by among other things, causing permitting and construction delays, project cancellations or increased project costs passed on to us. In September 2021, CenterPoint Energy announced its new net zero emission goals for Scope 1 and 2 emissions by 2035 and a 20-30% reduction in Scope 3 emissions by 2035 as compared to 2021 levels. Finally, we may be subject to climate change litigation, which could result in substantial fines, penalties or damages and restrictions on our operations. The oil and gas industry has already faced such litigation, challenging its marketing and use of fossil fuels and attributing climate change to emissions resulting from the use of fossil fuels, and other industries, including ours, could face such litigation in the future. For more information, see Note 7 to the consolidated financial statements, “— The February 2021 Winter Storm...” and “— CenterPoint Energy is subject to operational and financial risks..”

Aging infrastructure may lead to increased costs and disruptions in operations that could negatively impact our financial results.

We have risks associated with aging infrastructure assets, including the failure of equipment or processes and potential breakdowns due to such aging. The age of certain of our assets may result in a need for replacement or higher level of maintenance costs because of our risk-based federal and state compliant integrity management programs. Failure to achieve timely and full recovery of these expenses could adversely impact revenues and could result in increased capital expenditures or expenses. In addition, the nature of information available on aging infrastructure assets may make inspections, maintenance, upgrading and replacement of the assets particularly challenging. Also, our ability to successfully maintain or replace our aging infrastructure may be delayed or be at a greater cost than anticipated due to supply chain disruptions. Further, with respect to Natural Gas' operations, if certain pipeline replacements (for example, cast-iron or bare steel pipe) are not completed timely or successfully, government agencies and private parties might allege the uncompleted replacements caused events such as fires, explosions or leaks. Although we maintain insurance for certain of our facilities, our insurance coverage may not be sufficient in the event that a catastrophic loss is alleged to have been caused by a failure to timely complete equipment replacements. Insufficient insurance coverage and increased insurance costs could adversely impact our financial condition, results of operations and cash flows. Finally, aging infrastructure may complicate our utility operations ability to address climate change concerns and efforts to enhance resiliency and reliability. See “— Continued disruptions to the supply...”

Our businesses will continue to have to adapt to technological change and may not be successful or may have to incur significant expenditures to adapt to technological change.

We operate businesses that require sophisticated data collection, processing systems, software and other technology. Some of the technologies supporting the industries we serve are changing rapidly and increasing in complexity. New technologies will emerge or grow that may be superior to, or may not be compatible with, some of our existing technologies, and may require us to make significant investments and expenditures so that we can continue to provide cost-effective and reliable methods for energy production and delivery. Among such technological advances are distributed generation resources (e.g., private solar,



microturbines, fuel cells), energy storage devices and more energy-efficient buildings and products designed to reduce energy consumption and waste. As these technologies become a more cost-competitive option over time, whether through cost effectiveness or government incentives and subsidies, certain customers may choose to meet their own energy needs and subsequently decrease usage of our systems and services, including Indiana Electric's generating facilities becoming less competitive and economical. Further, certain regulatory and legislative bodies have introduced or are considering requirements and/or incentives to reduce energy consumption by certain dates. Additionally, technological advances driven by federal laws mandating new levels of energy efficiency in end-use electric and natural gas devices or other improvements in or applications of technology could lead to declines in per capita energy consumption.

Our future success will depend, in part, on our ability to anticipate and adapt to these technological changes in a cost-effective manner, to offer, on a timely basis, reliable services that meet customer demands and evolving industry standards, and to recover all, or a significant portion of, any unrecovered investment in obsolete assets. If we fail to adapt successfully to any technological change or obsolescence, fail to obtain access to important technologies or incur significant expenditures in adapting to technological change, or if implemented technology does not operate as anticipated, our businesses, financial condition, results of operations and cash flows could be materially and adversely affected.

Our potential business strategies and strategic initiatives, including merger and acquisition activities and the disposition of assets or businesses, may not be completed or perform as expected, adversely affecting our financial condition, results of operations and cash flows.

Our financial condition, results of operations and cash flows depend, in part, on our management’s ability to implement our business strategies successfully and realize the anticipated benefits therefrom. From time to time we have made, and may continue to make, acquisitions or divestitures of businesses and assets, such as our recently completed sale of our Natural Gas businesses in Arkansas and Oklahoma and the recently completed Enable Merger and subsequent sale of Energy Transfer Common Units and Energy Transfer Series G Preferred Units, form joint ventures or undertake restructurings. However, suitable acquisition candidates or potential buyers may not continue to be available on terms and conditions we find acceptable, or the expected benefits of completed acquisitions or dispositions may not be realized fully or at all, or may not be realized in the anticipated timeframe. If we are unable to make acquisitions, or if those acquisitions do not perform as anticipated, our future growth may be adversely affected. Further, any completed or future acquisitions involve substantial risks, including the following:

• acquired businesses or assets may not produce revenues, earnings or cash flow at anticipated levels;

• acquired businesses or assets could have environmental, permitting or other problems for which contractual protections prove inadequate;

- we may assume liabilities that were not disclosed to us, that exceed our estimates, or for which our rights to indemnification from the seller are limited;

- we may be unable to integrate acquired businesses successfully and realize anticipated economic, operational and other benefits in a timely manner, which could result in substantial costs and delays or other operational, technical or financial problems; and

- acquisitions, or the pursuit of acquisitions, could disrupt our ongoing businesses, distract management, divert resources and make it difficult to maintain current business standards, controls and procedures.

We are exposed to risks related to reduction in energy consumption due to factors such as changes in customers' perceptions from incidents of other utilities involving natural gas pipelines.

Our businesses are affected by reduction in energy consumption due to factors including economic, climate and market conditions in our service territories, energy efficiency initiatives, use of alternative technologies and changes in our customers' perceptions regarding natural gas usage as a result of incidents of other utilities involving natural gas pipelines, which could impact our ability to grow our customer base and our rate of growth. Growth in customer accounts and growth of customer usage each directly influences demand for electricity and natural gas and the need for additional delivery facilities. Customer growth and customer usage are affected by a number of factors outside our control, such as mandated energy efficiency measures, demand-side management goals, distributed generation resources and economic and demographic conditions, including population changes, job and income growth, housing starts, new business formation and the overall level of economic activity. Declines in demand for electricity and natural gas in our service territories due to pipeline incidents of other utilities, increased electricity and natural gas prices as experienced during the February 2021 Winter Storm Event and economic downturns, among other factors, could reduce overall usage and lessen cash flows, especially as industrial customers reduce production and, therefore, consumption of electricity and natural gas. Although Houston Electric's and Indiana Electric's transmission and distribution businesses are subject to regulated allowable rates of return and recovery of certain costs under periodic adjustment clauses, overall declines in electricity delivered and used as a result of economic downturn or recession



could reduce revenues and cash flows, thereby diminishing results of operations. A reduction in the rate of economic, employment and/or population growth could result in lower growth and reduced demand for and usage of electricity and natural gas in such service territories. Some or all of these factors could result in a lack of growth or decline in customer demand for electricity or natural gas or number of customers and may result in our failure to fully realize anticipated benefits from significant capital investments and expenditures, which could have a material adverse effect on our financial condition, results of operations and cash flows.

## General Risk Factors Affecting Our Businesses

Cyberattacks, physical security breaches, acts of terrorism or other disruptions could adversely impact our reputation, financial condition, results of operations and cash flows.

We are subject to cyber and physical security risks related to adversaries attacking information technology systems, network infrastructure, technology and facilities used to conduct almost all of our businesses, which includes, among other things, (i) managing operations and other business processes and (ii) protecting sensitive information maintained in the normal course of business. For example, the operation of our electric generation, transmission and distribution systems are dependent on not only physical interconnection of our facilities but also on communications among the various components of our systems and third-party systems. This reliance on information and communication between and among those components has increased since deployment of the intelligent grid, smart devices and operational technologies across our businesses. Further, certain of the various internal systems we use to conduct our businesses are highly integrated. Consequently, a cyberattack or unauthorized access in any one of these systems could potentially impact the other systems. Similarly, our business operations are interconnected with external networks and facilities. For example, the operation of an efficient deregulated wholesale and retail electric market in Texas mandates communication with ERCOT, and competitive retailers; and our Indiana Electric organization has a similar relationship with MISO. Also, the distribution of natural gas to our customers requires communications with third-party systems. Disruption of those communications, whether caused by physical disruption such as storms or other natural disasters, by failure of equipment or technology or by manmade events, such as cyberattacks or acts of terrorism, may disrupt our ability to conduct operations and control assets.

Cyberattacks, including phishing attacks and threats from the use of malicious code such as malware, ransomware and viruses, and unauthorized access could also result in the loss, or unauthorized use, of confidential, proprietary or critical infrastructure data or security breaches of other information technology systems that could disrupt operations and critical business functions, adversely affect reputation, increase costs and subject us to possible legal claims and liability. While we have implemented and maintain a cybersecurity program designed to protect our information technology, operational technology, and data systems from such attacks, our cybersecurity program does not prevent all breaches or cyberattack incidents. We have experienced an increase in the number of attempts by external parties to access our networks or our company data without authorization. We have experienced, and expect to continue to experience, cyber intrusions and attacks to our information systems and those of third parties, including vendors, suppliers, contractors and quasi government entities, like ERCOT and MISO, who perform certain services for us or administer and maintain our sensitive information. The risk of a disruption or breach of our operational systems, or the compromise of the data processed in connection with our operations, through cybersecurity breach or ransomware attack has increased as attempted attacks have advanced in sophistication and number around the world. We are not fully insured against all cybersecurity risks, any of which could adversely affect our reputation and could have a material adverse effect on our financial condition, results of operations and cash flows.

We depend on the secure operations of our physical assets to transport the energy we deliver and our information technology to process, transmit and store electronic information, including information and operational technology we use to safely operate our energy transportation systems. Security breaches or acts of terrorism could expose our business to a risk of loss, misuse or interruption of critical physical assets or information and functions that affect our operations, as well as potential data privacy breaches and loss of protected personal information. Such losses could result in operational impacts, damage to our assets, public or personal safety incidents, damage to the environment, reputational harm, competitive disadvantage, regulatory enforcement actions, litigation and a potential material adverse effect on our operations, financial condition, results of operations and cash flows. There is no certainty that costs incurred related to securing against security threats will be completely recoverable through rates.



Compliance with and changes in cybersecurity laws and regulations have a cost and operational impact on our business, and failure to comply with such requirements could adversely impact our reputation, financial condition, results of operations and cash flows.

Cyberattacks are becoming more sophisticated, and U.S. government warnings have indicated that infrastructure assets, including pipelines and electric generation and infrastructure, may be specifically targeted by certain groups. In the second and third quarters of 2021, the TSA announced two new security directives in response to a ransomware attack on the Colonial Pipeline that occurred in 2021. These directives require critical pipeline owners to comply with mandatory reporting measures, designate a cybersecurity coordinator, provide vulnerability assessments, and ensure compliance with certain cybersecurity requirements. We may be required to expend significant additional resources and costs to respond to cyberattacks, to continue to modify or enhance our protective measures, or to assess, investigate and remediate any critical infrastructure security vulnerabilities. There is no certainty that such costs incurred will be recovered through rates. Any failure to remain in compliance with these government regulations or failure in our cybersecurity protective measures may result in enforcement actions which may have a material adverse effect on our reputation, financial condition, results of operations and cash flows.

## Failure to maintain the security of personally identifiable information could adversely affect us.

In connection with our businesses, we and our vendors, suppliers and contractors collect and retain personally identifiable information (for example, information of our customers, shareholders, suppliers and employees), and there is an expectation that we and such third parties will adequately protect that information. The regulatory environment surrounding information security and data privacy is increasingly demanding. New laws and regulations governing data privacy and the unauthorized disclosure of confidential information pose increasingly complex compliance challenges and elevate our costs. Any failure by us to comply with these laws and regulations, including as a result of a security or privacy breach, could result in significant costs, fines and penalties and liabilities for us. While we have implemented and maintain a data privacy program designed to protect personal information from any attacks, our data privacy programs does not prevent all security or privacy breaches. Some of our third party vendors who maintain personally identifiable information have experienced a breach of their data privacy. A significant theft, loss or fraudulent use of the personally identifiable information we maintain or failure of our vendors, suppliers and contractors to use or maintain such data in accordance with contractual provisions and other legal requirements could adversely impact our reputation and could result in significant costs, fines and penalties and liabilities for us. Additionally, if we acquire a company that has violated or is not in compliance with applicable data protection laws, we may incur significant liabilities and penalties as a result.

Our insurance coverage may not be sufficient. Insufficient insurance coverage and increased insurance costs could adversely impact our financial condition, results of operations and cash flows.

We currently have insurance in place, such as general liability and property insurance, to cover certain of our facilities in amounts that we consider appropriate. Such policies are subject to certain limits and deductibles and do not include business interruption coverage. Insurance coverage may not be available in the future at current costs or on commercially reasonable terms, and the insurance proceeds received for any loss of, or any damage to, any of our facilities may not be sufficient to fully cover or restore the loss or damage without negative impact on our financial condition, results of operations and cash flows. Costs, damages and other liabilities related to recent events and incidents that affected other utilities, such as wildfires, winter storms and explosions, among other things, have exceeded or could exceed such utilities' insurance coverage. Further, as a result of these recent events and incidents, the marketplace for insurance coverage to utility companies may be unavailable or limited in capacity or any such available coverage may be deemed by us to be cost prohibitive under current conditions. Insurance premiums for any such coverage, if available, may not be eligible for recovery, whether in full or in part, by us through the rates charged by our utility businesses.

In common with other companies in its line of business that serve coastal regions, Houston Electric does not have insurance covering its transmission and distribution system, other than substations, because Houston Electric believes it to be cost prohibitive and insurance capacity to be limited. Historically, Houston Electric has been able to recover the costs incurred in restoring its transmission and distribution properties following hurricanes or other disasters through issuance of storm restoration bonds or a change in its regulated rates or otherwise. In the future, any such recovery may not be granted. Therefore, Houston Electric may not be able to restore any loss of, or damage to, any of its transmission and distribution properties without negative impact on its financial condition, results of operations and cash flows.



We face risks related to COVID-19 and other health epidemics and outbreaks, including economic, regulatory, legal, workforce and cyber security risks, which could adversely impact our financial condition, results of operations, cash flows and liquidity.

The COVID-19 pandemic continues to evolve and adversely affect current global economic activities and conditions. An extended slowdown of economic growth, decreased demand for commodities and/or material changes in governmental or regulatory policy in the United States has resulted in, and could continue to result in, lower growth and reduced demand for and usage of electricity and natural gas in our service territories, particularly among our commercial and industrial customers, as customer facilities close, remain closed or potentially close again. The ability of our customers, contractors and suppliers to meet their obligations to us, including payment obligations, has also been negatively affected under the current economic conditions and previously resulted in an increase to allowance for credit losses. To the extent these conditions in our service territories persist, our bad debt expense from uncollectible accounts could continue to increase, negatively impacting our financial condition, results of operations and cash flows. REPs have and could continue to encounter financial difficulties, including bankruptcies, which could impair their ability to pay for Houston Electric’s services or could cause them to delay such payments, adversely affecting Houston Electric’s cash flows and liquidity. Additionally, our state and local regulatory agencies, in response to a federal mandate or otherwise, could impose restrictions on the rates we charge to provide our services, including the inability to implement approved rates, or delay actions with respect to our rate cases and filings. The COVID-19 pandemic may affect our ability to timely satisfy regulatory requirements such as recordkeeping and/or timely reporting requirements. For further information on COVID-19 regulatory matters, please see Note 7 to the consolidated financial statements, which information is incorporated herein by reference.

Additionally, various federal, state, and local governmental entities continue to pass legislation, issue orders, and take other measures to respond to the COVID-19 pandemic, including vaccination, testing and masking requirements. Some of these governmental requirements conflict with others presenting challenges to businesses like ours in interpreting, implementing, and complying with them. Governmental requirements have also been subject to challenges in litigation, such as OSHA’s Emergency Temporary Standard, mandating vaccination for certain employers, which was recently withdrawn by OSHA after being stayed by the Supreme Court of the United States.

With respect to our supply chain, to the extent we experience such disruptions in our supply chain that limit our ability to obtain materials and equipment necessary for our businesses, whether through delayed order fulfillment, limited production or unavailability due to COVID-19, we may be unable to perform our operations timely or as anticipated, which could result in service or construction delays, project cancellations or increased costs. Furthermore, in the event key officers or a substantial portion of our workforce were to be impacted by COVID-19 for an extended period of time, we may face challenges with respect to our services or operations and we may not be able to execute our capital plan as anticipated. There is considerable uncertainty regarding the extent to which COVID-19 and its variants will continue to spread, even with the availability of a vaccine therefor, and the extent and duration of governmental and other measures implemented to try to slow the spread of COVID-19 and variants, such as large-scale travel bans and restrictions, border closures, quarantines, shelter-in-place orders and business and government shutdowns. Restrictions of this nature have caused, and may continue to cause, us, our suppliers and other business counterparties to experience operational delays, shortages of employees, materials and equipment, facility shutdowns or business closures. As appropriate, based on conditions, we have modified certain business and workforce practices (including those related to employee travel, employee work locations and participation in meetings, events and conferences) to conform to government restrictions and best practices encouraged by governmental and regulatory authorities. However, the quarantine of personnel or the inability to access our facilities or customer sites could adversely affect our operations. While certain of our personnel have been, and may continue to be, quarantined, our operations and corporate functions have not been significantly adversely affected to date. As of the date of this Form 10-K, the vast majority of our workforce works from their regular work locations. As appropriate, we have adjusted our operational protocols to minimize exposure and risk to our field personnel, customers and the communities we serve, while continuing to maintain the work activities necessary for safe and reliable service to our customers. Even with increased safety precautions, we cannot assure that such adjustments and precautions will be sufficient to minimize exposure to and risk from COVID-19. Also, we have a limited number of highly skilled employees for some of our operations. If a large proportion of our employees in those critical positions were to contract COVID-19 at the same time, we would rely upon our business continuity plans in an effort to continue operations at our facilities, but there is no certainty that such measures will be sufficient to mitigate the adverse impact to our operations that could result from shortages of highly skilled employees. Additionally, in the event that customers, contractors, employees or others were to allege that they contracted COVID-19 because of actions we took or failed to take, we could face claims, lawsuits and potential legal liability. In addition to the reasonableness of our actions and efforts to comply with applicable COVID-19 guidance, our exposure and ultimate liability would depend upon the applicability of workers' compensation, the availability of insurance coverage and limitations on liability being considered or enacted at the state and federal level. For more information, see “— Continued disruptions to the supply...”



Experts have observed an increase in the volume and the sophistication of cyberattacks since the beginning of the COVID-19 pandemic. Any technology system breaches and/or data privacy incidents could disrupt our operations or result in the loss or exposure of confidential or sensitive customer, employee or company information and adversely affect our business, financial condition and results of operations. For those employees and third-party service providers who continue to work remotely, we face heightened cyber security and privacy risks related to unauthorized system access, aggressive social engineering tactics and adversaries attacking the information technology systems, network infrastructure, technology and facilities used to conduct our business. The increase in the remote working arrangements of our employees initially as a result of the COVID-19 pandemic required enhancements and modifications to our information technology infrastructure (for example, virtual private network, or VPN, and remote collaboration systems), and any failures of these technologies, including third-party service providers, that facilitate working remotely could limit our ability to conduct our ordinary operations and expose us to increased risk or impact of a cyberattack. See “— Cyberattacks, physical security breaches, acts...”

We will continue to monitor developments affecting our employees, customers and operations. At this time, however, we cannot predict the extent or duration of the COVID-19 pandemic or its future effects on national, state and local economies, including the impact on our ability to access capital markets, our supply chain, our business strategies and plans and our workforce, nor can we estimate the potential adverse impact from COVID-19 on our financial condition, results of operations, cash flows and liquidity. Other future epidemics and outbreaks may result in potential adverse impacts similar to, or worse than, those from COVID-19.

Our success depends upon our ability to attract, effectively transition, motivate and retain key employees and identify and develop talent to succeed senior management.

We depend on senior executive officers and other key personnel. Our success depends on our ability to attract, effectively transition and retain key personnel. Further tightening of the labor market and increasing wages to attract and retain key personnel may adversely affect our ability to attract and retain key personnel. The inability to recruit and retain or effectively transition key personnel or the unexpected loss of key personnel may adversely affect our operations. In addition, because of the reliance on our management team, our future success depends in part on our ability to identify and develop talent to succeed senior management. The retention of key personnel and appropriate senior management succession planning will continue to be critically important to the successful implementation of our strategies.

Failure to attract and retain an appropriately qualified workforce and maintain good labor relations could adversely impact the operations of our facilities and our results of operations.

Our businesses are dependent on recruiting, retaining and motivating employees. Like many companies in the utilities industry and other industries, we have experienced higher than normal turnover of employees as a result of a number of factors, including the COVID-19 pandemic, a tightening labor market, increasing remote working opportunities, employees shifting industries, individuals deciding not to work and a maturing workforce. Certain circumstances, such as an aging workforce without appropriate replacements, a mismatch of existing skillsets to future needs, or the unavailability of contract resources may lead to operating challenges such as a lack of resources, loss of knowledge or a lengthy time period associated with skill development. Our costs, including costs to replace employees, productivity costs and safety costs, may rise. Failure to hire and adequately train replacement employees, including the transfer of significant internal historical knowledge and expertise to the new employees, or the future availability and cost of contract labor may adversely affect the ability to manage and operate our businesses, particularly the specialized skills and knowledge required to construct and operate generation facilities, a technology-enabled power grid and transmission and distribution facilities, among other facilities. If we are unable to successfully attract and retain an appropriately qualified workforce, our ability to execute on our 10-year capital plan and our results of operations could be negatively affected.

Furthermore, the operations of our facilities depends on good labor relations with our employees, and several of our businesses have in place collective bargaining agreements with different labor unions, comprising approximately 37% of our workforce. We have several separate bargaining units, each with a unique collective bargaining agreement described further in Note 8(j) to the consolidated financial statements, which information is incorporated herein by reference. The collective bargaining agreements with USW Locals 13-227, USW Locals 13-1 and IBEW Local 702 related to Natural Gas and CenterPoint Energy employees are scheduled to expire in June 2022, July 2022 and June 2022, respectively, and negotiations of these agreements are expected to be completed before the respective expirations. Any failure to reach an agreement on new labor contracts or to negotiate these labor contracts might result in strikes, boycotts or other labor disruptions. These potential labor disruptions could have a material adverse effect on our businesses, results of operations and/or cash flows. Labor disruptions, strikes or significant negotiated wage and benefit increases, whether due to union activities, employee turnover or otherwise, could have a material adverse effect on our businesses, results of operations and cash flows.



Changing demographics, poor investment performance of pension plan assets and other factors adversely affecting the calculation of pension liabilities could unfavorably impact our financial condition, results of operations and liquidity.

CenterPoint Energy and its subsidiaries maintain qualified defined benefit pension plans covering certain of its employees. Costs associated with these plans are dependent upon a number of factors including the investment returns on plan assets, the level of interest rates used to calculate the funded status of the plan, contributions to the plan, the number of plan participants and government regulations with respect to funding requirements and the calculation of plan liabilities. Funding requirements may increase and CenterPoint Energy may be required to make unplanned contributions in the event of a decline in the market value of plan assets, a decline in the interest rates used to calculate the present value of future plan obligations, or government regulations that increase minimum funding requirements or the pension liability. In addition to affecting CenterPoint Energy’s funding requirements, these factors could adversely affect our financial condition, results of operations and liquidity.

We may be significantly affected by changes in federal income tax laws and regulations, including any comprehensive federal tax reform legislation.

Our businesses are impacted by U.S. federal income tax policy. Under the current administration with the Senate and House of Representatives controlled by the Democratic Party, comprehensive federal tax reform legislation could be enacted that may significantly change the federal income tax laws applicable to domestic businesses, including changes that may increase the federal income tax rate and impact investment incentives and deductions for depreciation and interest, among other deductions. While CenterPoint Energy and its subsidiaries cannot assess the overall impact of any such potential legislation on our businesses, it is possible that our financial condition, results of operations or cash flows could be negatively impacted. Furthermore, with any enacted federal tax reform legislation, it is uncertain how state commissions and local municipalities may require us to respond to the effects of such tax legislation, including determining the treatment of EDIT and other increases and decreases in our revenue requirements. As such, potential regulatory actions in response to any enacted tax legislation could adversely affect our financial condition, results of operations and cash flows.

We are involved in numerous legal proceedings, the outcomes of which are uncertain, and resolutions adverse to us could negatively affect our financial results.

The Registrants are subject to numerous legal proceedings, the most significant of which are summarized in Note 16 to the consolidated financial statements to the Registrants' respective consolidated financial statements. Litigation is subject to many uncertainties, and recent trends suggest that jury verdicts and other liability have been increasing, and the Registrants cannot predict the outcome of all matters with assurance. Additionally, under some circumstances, the Registrants could potentially have claims filed against them or incur liabilities associated with assets and businesses no longer owned by them as a result of sales, divestitures or other transfers to third parties who may be unable to fulfill their indemnity obligations to the Registrants. Final resolution of these matters, or any potential future claims or liabilities, may require additional expenditures over an extended period of time that may be in excess of established insurance or reserves and may have a material adverse effect on the Registrants' financial results.

Our businesses may be adversely affected by the intentional misconduct of our employees.

We are committed to living our core values of safety, integrity, accountability, initiative and respect and complying with all applicable laws and regulations. Despite that commitment and efforts to prevent misconduct, it is possible for employees to engage in intentional misconduct, fail to uphold our core values, and violate laws and regulations for individual gain through contract or procurement fraud, misappropriation, bribery or corruption, fraudulent related-party transactions and serious breaches of our Ethics and Compliance Code and other policies. If such intentional misconduct by employees should occur, it could result in substantial liability, higher costs, increased regulatory scrutiny and negative public perceptions, any of which could have a material adverse effect on our financial condition, results of operations and cash flows. From time to time, including as part of our Ethics and Compliance program’s efforts to detect misconduct, we become aware of and expect to continue to become aware of instances of employee misconduct, which we investigate, remediate and disclose as appropriate and proportionate to the incident.

## Reportable Segments

In this Management’s Discussion and Analysis, we discuss our results from continuing operations on a consolidated basis and individually for each of our reportable segments, which are listed below. We also discuss our liquidity, capital resources and critical accounting policies. We are first and foremost an energy delivery company and it is our intention to remain focused on these segments of the energy business. The results of our business operations are significantly impacted by weather, customer growth, economic conditions, cost management, competition, rate proceedings before regulatory agencies and other actions of the various regulatory agencies to whose jurisdiction we are subject, among other factors.

As of December 31, 2021, CenterPoint Energy’s reportable segments were Electric and Natural Gas.

- The Electric reportable segment includes electric transmission and distribution services that are subject to rate regulation in Houston Electric’s and Indiana Electric’s service territories, as well as the impacts of generation-related stranded costs and other true-up balances recoverable by the regulated electric utility and energy delivery services to electric customers and electric generation assets to serve electric customers and optimize those assets in the wholesale power market in Indiana Electric’s service territory. For further information about the Electric reportable segment, see “Business — Our Business — Electric” in Item 1 of Part I of this report.

- The Natural Gas reportable segment includes natural gas distribution services that are subject to rate regulation in CenterPoint Energy’s and CERC’s service territories, as well as home appliance maintenance and repair services to customers in Minnesota and home repair protection plans to natural gas customers in Arkansas, Indiana, Mississippi, Ohio, Oklahoma and Texas through a third party as of December 31, 2021.

# EXECUTIVE SUMMARY

We expect our businesses to continue to be affected by the key factors and trends discussed below. Our expectations are based on assumptions made by us and information currently available to us. To the extent our underlying assumptions about, or interpretations of, available information prove to be incorrect, our actual results may vary materially from our expected results.

## Factors Influencing Our Businesses and Industry Trends

We are an energy delivery company. The majority of our revenues are generated from the transmission and delivery of electricity and the sale of natural gas by our subsidiaries.

As announced in December 2020, our business strategy incorporated the Business Review and Evaluation Committee’s recommendations to increase our planned capital expenditures in our electric and natural gas businesses to support rate base growth and sell certain of our Natural Gas businesses located in Arkansas and Oklahoma as a means to efficiently finance a portion of such increased capital expenditures. The sale of our Natural Gas businesses in Arkansas and Oklahoma was completed in January 2022. See Note 4 to the consolidated financial statements for further details.

In February 2021, we announced our support for the Enable Merger, which closed in December 2021. At our September 2021 analyst day, we announced our plans to exit the midstream sector by the end of 2022 and become a pure-play utility focusing on growth in our existing service territories. In September 2021, we entered into a Forward Sale Agreement to sell 50 million Energy Transfer Common Units immediately following the closing of the Enable Merger. In December 2021, we completed sales of 150 million Energy Transfer Common Units (inclusive of the Energy Transfer Common Units sold pursuant to the Forward Sale Agreement) and 192,390 Energy Transfer Series G Preferred Units for net proceeds of $1,320 million. See Note 12 to the consolidated financial statements for further details.

The regulation of natural gas pipelines and related facilities by federal and state regulatory agencies affects CenterPoint Energy’s and CERC’s businesses. In accordance with natural gas pipeline safety and integrity regulations, CenterPoint Energy and CERC are making, and will continue to make, significant capital investments in their service territories, which are necessary to help operate and maintain a safe, reliable and growing natural gas system. CenterPoint Energy’s and CERC’s compliance expenses may also increase as a result of preventative measures required under these regulations. Consequently, new rates in the areas they serve are necessary to recover these increasing costs.

To assess our financial performance, our management primarily monitors recovery of costs and return on investments by the evaluation of net income and cash flows, among other things, from our regulated service territories within our reportable segments. Within these broader financial measures, we monitor margins, natural gas and fuel costs, interest expense, capital spending working capital requirements, and operation and maintenance expense. In addition to these financial measures, we also monitor a number of variables that management considers important to gauge the performance of our reportable segments, including the number of customers, throughput, use per customer, commodity prices, heating and cooling degree days, environmental impacts, safety factors, system reliability and customer satisfaction.

The nature of our businesses requires significant amounts of capital investment, particularly in light of our new 10-year capital plan, and we rely on internally generated cash, borrowings under our credit facilities, proceeds from commercial paper and issuances of debt and equity in the capital markets to satisfy these capital needs. Proceeds from future dispositions of Energy Transfer Common Units or Energy Transfer Series G Preferred Units could reduce borrowings or provide additional support for our capital investment needs. With respect to CERC, we intend to use proceeds from the completed dispositions of our Natural Gas businesses in Arkansas and Oklahoma and any potential further asset sales to satisfy a portion of its capital needs. We strive to maintain investment grade ratings for our securities to access the capital markets on terms we consider reasonable. A reduction in our ratings generally would increase our borrowing costs for new issuances of debt, as well as borrowing costs under our existing revolving credit facilities, and may prevent us from accessing the commercial paper markets. Disruptions in the financial markets can also affect the availability of new capital on terms we consider attractive. In those circumstances, we may not be able to obtain certain types of external financing or may be required to accept terms less favorable than they would otherwise accept. For that reason, we seek to maintain adequate liquidity for our businesses through existing credit facilities and prudent refinancing of existing debt.

To the extent adverse economic conditions, including supply chain disruptions, affect our suppliers and customers, results from our energy delivery businesses may suffer. Each state has a unique economy and is driven by different industrial sectors. Our largest customers reflect the diversity in industries in the states across our footprint. For example, Houston Electric is largely concentrated in Houston, Texas, a diverse economy where a higher percentage of employment is tied to the energy sector relative to other regions of the country. Although the Houston area represents a large part of our customer base, we have



a diverse customer base throughout the various states our utility businesses serve. In Minnesota, for instance, education and health services are the state’s largest sectors. Indiana and Ohio are impacted by changes in the Midwest economy in general and changes in particular industries concentrated in the Midwest such as automotive, feed and grain processing. Some industries are driven by population growth like education and health care, while others may be influenced by strength in the national or international economy.

Further, the global supply chain has experienced significant disruptions due to a multitude of factors, such as labor shortages, resource availability, long lead times, inflation and weather. These disruptions have adversely impacted the utility industry. Like many of our peers, we have experienced disruptions to our supply chain and may continue to experience such disruptions in the future. For example, we, along with the developer of the project, recently announced plans to downsize the solar array to be built in Posey County, Indiana from 300 MW to 200 MW due to supply chain issues experienced in the energy industry, rising cost of commodities and community feedback. For more information, see Note 16 to the consolidated financial statements.

Also, adverse economic conditions, coupled with concerns for protecting the environment and increased availability of alternate energy sources, may cause consumers to use less energy or avoid expansions of their facilities, including natural gas facilities, resulting in less demand for our services. Long-term national trends indicate customers have reduced their energy consumption, which could adversely affect our results. However, due to more affordable energy prices and continued economic improvement in the areas we serve, the trend toward lower usage has slowed. To the extent population growth is affected by lower energy prices and there is financial pressure on some of our customers who operate within the energy industry, there may be an impact on the growth rate of our customer base and overall demand. Lower interest rates have helped single family housing starts in the Houston and Minneapolis to exceed growth in previous years. Multifamily residential customer growth is affected by the cyclical nature of apartment construction. A new construction cycle in Houston helped overall residential customer growth to surpass the long-term trend of 2% for the last two years. Management expects residential meter growth for Houston Electric to remain in line with long term trends at approximately 2%. Typical customer growth in the jurisdictions served by the Natural Gas reportable segment is approximately 1%. Management expects residential meter growth for CERC to remain in line with long term trends at approximately 1%.

## Significant Events

Sale of Natural Gas Businesses. On April 29, 2021, CenterPoint Energy, through its subsidiary CERC Corp., entered into an Asset Purchase Agreement to sell its Arkansas and Oklahoma Natural Gas businesses for $2.15 billion in cash, including recovery of approximately $425 million in gas cost, including storm-related incremental natural gas costs incurred in the February 2021 Winter Storm Event, subject to certain adjustments set forth in the Asset Purchase Agreement. The sale closed on January 10, 2022. On August 31, 2021, CenterPoint Energy, through its subsidiary CERC Corp., completed the sale of MES to Last Mile Energy. For further information, see Note 4 to the consolidated financial statements.

Net Zero Emission Goals. In September 2021, CenterPoint Energy announced new net zero emission goals for both Scope 1 and certain Scope 2 emissions by 2035 as well as a goal to reduce certain Scope 3 emissions by 20% to 30% by 2035. For more information regarding CenterPoint Energy’s new net zero emission goals and the risks associated with them, see “Risk Factors — Risk Factors Affecting Our Businesses — CenterPoint Energy is subject to operational and financial risks...” and “Management’s Discussion and Analysis — Liquidity and Capital Resources” in this Form 10-K.

February 2021 Winter Storm Event. In February 2021, portions of the United States experienced an extreme and unprecedented winter weather event that resulted in corresponding electricity generation shortages, including in Texas, natural gas shortages and increased wholesale prices of natural gas in the United States. Many customers of Houston Electric’s REPs and, to a lesser extent, of CERC, were severely impacted by outages in electricity and natural gas delivery during the February 2021 Winter Storm Event. As a result of this weather event, the governors of Texas, Oklahoma and Louisiana declared states of either disaster or emergencies in their respective states. Subsequently, President Biden also approved major disaster declarations for all or parts of Texas, Oklahoma and Louisiana.

The February 2021 Winter Storm Event resulted in financial impacts to CenterPoint Energy, Houston Electric and CERC, including substantial increases in prices for natural gas, decreased revenues at Houston Electric due to ERCOT-mandated outages, additional interest expense related to external financing to pay for natural gas working capital, significant impacts to the REPs, including the REPs' ability to pay invoices from Houston Electric, increases in bad debt expense, issues with counterparties and customers, litigation and investigations or inquiries from government or regulatory agencies and entities, and other financial impacts. CenterPoint Energy does not, at this time, anticipate long-term financial impacts associated with the February 2021 Winter Storm Event, including changes to its credit profile, credit ratings or liquidity, given the regulatory mechanisms that are in place in our jurisdictions to recover the extraordinary expenses. CenterPoint Energy is, however,



continuing to work with individual regulatory agencies to reach a successful final resolution on the recovery of the extraordinary costs. For more information regarding regulatory impacts, debt transactions and litigation, see Notes 7, 14 and 16 to the consolidated financial statements and “—Liquidity and Capital Resources —Future Sources and Uses of Cash” and “—Regulatory Matters” below.

Enable Merger Agreement. On February 16, 2021, Enable entered into the Enable Merger Agreement. On December 2, 2021, the Enable Merger closed pursuant to the Enable Merger Agreement. At the closing of the Enable Merger, CenterPoint Energy transferred 100% of the Enable Common Units and Enable Series A Preferred Units it owned in exchange for Energy Transfer Common Units and Energy Transfer Series G Preferred Units, respectively. In December 2021, we completed sales of approximately 75% of the acquired Energy Transfer Common Units and 50% of Energy Transfer Series G Preferred Units for net proceeds of $1,320 million. For more information, see Notes 4, 11 and 12 to the consolidated financial statements.

Debt Transactions. In 2021, CenterPoint Energy, Houston Electric and CERC issued a combined $4.5 billion in new debt and repaid or redeemed a combined $2.7 billion of debt, excluding scheduled principal payments on Securitization Bonds. Additionally, on January 31, 2022, CERC Corp. redeemed $425 million aggregate principal amount of CERC’s outstanding senior notes due 2023. For further information about debt transactions in 2021 and to date in 2022, see Note 12 to the consolidated financial statements.

Preferred Stock Conversions. For information regarding preferred stock conversions in 2021, see Note 19 to the consolidated financial statements.

Regulatory Proceedings. For information related to our pending and completed regulatory proceedings in 2021 and to date in 2022, see “—Liquidity and Capital Resources —Regulatory Matters” below.

Board of Directors Governance Structure. On July 22, 2021, CenterPoint Energy announced the decision of the independent directors of the Board to implement a new independent Board leadership and governance structure and appointed a new independent chair of the Board. To implement this new governance structure, the independent directors of the Board eliminated the Executive Chairman position. For further information, see Note 8 to the consolidated financial statements.

## CENTERPOINT ENERGY CONSOLIDATED RESULTS OF OPERATIONS

CenterPoint Energy’s results of operations are affected by seasonal fluctuations in the demand for electricity and natural gas. CenterPoint Energy’s results of operations are also affected by, among other things, the actions of various governmental authorities having jurisdiction over rates its subsidiaries charge, debt service costs, income tax expense, its subsidiaries ability to collect receivables from REPs and customers and its ability to recover its regulatory assets. For information regarding factors that may affect the future results of our consolidated operations, please read “Risk Factors” in Item 1A of Part I of this report.

Income (loss) available to common shareholders for the years ended December 31, 2021, 2020 and 2019 was as follows:

(1) Includes only February 1, 2019 through December 31, 2019 results of acquired electric and natural gas businesses due to the Merger.

(2) Includes energy performance contracting and sustainable infrastructure services through Energy Systems Group, unallocated corporate costs, interest income and interest expense, intercompany eliminations and the reduction of income allocated to preferred shareholders.

## 2021 Compared to 2020

Net Income. CenterPoint Energy reported income available to common shareholders of $1,391 million for 2021 compared to a loss available to common shareholders of $949 million for 2020.

The increase in income available to common shareholders of $2,340 million was primarily due to the following key factors:

- an increase in earnings from discontinued operations primarily related to the Enable Merger discussed further in Note 4 to the consolidated financial statements and the 2020 impairment in Enable discussed further in Notes 10 and 11 to the consolidated financial statements;

• goodwill impairment at Indiana Electric in 2020;

- the dividend requirement and amortization of beneficial conversion feature associated with Series C Preferred Stock in 2020; and

• favorable income tax impacts in 2021, partially offset by the CARES Act in 2020.

These increases were partially offset by:

• losses on the sale of Energy Transfer Common Units and Energy Transfer Series G Preferred Units in 2021;

• make-whole premiums on debt redeemed in 2021; and

• the impact of the Board-implemented governance changes announced in July 2021.

Excluding those items, income available to common shareholders increased $191 million primarily due to the following key factors:

• rate relief, net of increases in depreciation and amortization and taxes other than income taxes;

• reduced impact of COVID-19;

• continued customer growth; and



• reduced interest expense.

## 2020 Compared to 2019

Net Income. CenterPoint Energy reported a loss available to common shareholders of $949 million for 2020 compared to income available to common shareholders of $674 million for 2019.

The decrease in income available to common shareholders of $1,623 million was primarily due to the following key factors:

• a decrease in earnings from discontinued operations as a result of the 2020 impairment in Enable discussed further in Note 10 and 11 to the consolidated financial statements;

• goodwill impairment at Indiana Electric in 2020; and

- the dividend requirement and amortization of beneficial conversion feature associated with Series C Preferred Stock in 2020

These decreases were partially offset by the CARES Act in 2020.

Excluding those items, income available to common shareholders increased $115 million primarily due to the following key factors:

• rate relief, net of increases in depreciation and amortization and taxes other than income taxes;

• continued customer growth;

• operation and maintenance expense discipline; and

• the impact of twelve months in 2020 versus eleven months in 2019 for businesses acquired in the Merger.

These increases were partially offset by the impact of COVID-19.

Discontinued Operations. In September 2021, CenterPoint Energy’s equity investment in Enable met the held for sale criteria. On December 2, 2021, Enable completed the previously announced Enable Merger pursuant to the Enable Merger Agreement entered into on February 16, 2021. CenterPoint Energy’s plan to exit its Midstream Investment reportable segment in 2022 represents a strategic shift to CenterPoint Energy. Therefore, the assets and liabilities associated with the equity investment in Enable are reflected as discontinued operations on CenterPoint Energy’s Statements of Consolidated Income, and the December 31, 2020 Consolidated Balance Sheet was required to be recast for assets held for sale. For further information, see Note 4 to the consolidated financial statements.

On February 3, 2020, CenterPoint Energy, through its subsidiary VUSI, entered into the Securities Purchase Agreement to sell the Infrastructure Services Disposal Group. Accordingly, the previously reported Infrastructure Services reportable segment has been eliminated. The transaction closed on April 9, 2020. For further information, see Note 4 to the consolidated financial statements.

Additionally, on February 24, 2020, CenterPoint Energy, through its subsidiary CERC Corp., entered into the Equity Purchase Agreement to sell the Energy Services Disposal Group. Accordingly, the previously reported Energy Services reportable segment has been eliminated. The transaction closed on June 1, 2020. For further information, see Note 4 to the consolidated financial statements.

Income Tax Expense. For a discussion of effective tax rate per period, see Note 15 to the consolidated financial statements.

## CENTERPOINT ENERGY'S RESULTS OF OPERATIONS BY REPORTABLE SEGMENT

CenterPoint Energy’s CODM views net income as the measure of profit or loss for the reportable segments. Segment results include inter-segment interest income and expense, which may result in inter-segment profit and loss.

The following discussion of results of operations by reportable segment concentrates on CenterPoint Energy’s Utility Operations, conducted through two reportable segments, Electric and Natural Gas. CenterPoint Energy’s formerly reported Midstream Investments reportable segment results are now included in discontinued operations. For additional information regarding the Midstream Investments reportable segment, see Notes 4, 10, 11 and 18 to the consolidated financial statements.

Income Tax Expense. For a discussion of effective tax rate per period, see Note 15 to the consolidated financial statements.



CERC’s CODM views net income as the measure of profit or loss for its reportable segment. CERC consists of a single reportable segment. CERC’s results of operations are affected by seasonal fluctuations in the demand for natural gas. CERC’s results of operations are also affected by, among other things, the actions of various federal, state and local governmental authorities having jurisdiction over rates CERC charges, debt service costs and income tax expense, CERC’s ability to collect receivables from customers and CERC’s ability to recover its regulatory assets. For information regarding factors that may affect the future results of CERC’s consolidated operations, please read “Risk Factors” in Item 1A of Part I of this report.

Discontinued Operations. On February 24, 2020, CenterPoint Energy, through its subsidiary CERC Corp., entered into the Equity Purchase Agreement to sell the Energy Services Disposal Group. Accordingly, the previously reported Energy Services reportable segment has been eliminated. The transaction closed on June 1, 2020. For further information, see Note 4 to the consolidated financial statements.

## Future Sources and Uses of Cash

The Registrants expect that anticipated 2022 cash needs will be met with borrowings under their credit facilities, proceeds from the issuance of long-term debt, term loans or common stock, anticipated cash flows from operations, with respect to CenterPoint Energy and CERC, proceeds from commercial paper, and with respect to CenterPoint Energy, distributions from Energy Transfer or proceeds from future dispositions of Energy Transfer Common Units or Energy Transfer Series G Preferred Units, and, with respect to CERC, proceeds from any potential asset sales. Discretionary financing or refinancing may result in the issuance of equity securities of CenterPoint Energy or debt securities of the Registrants in the capital markets or the arrangement of additional credit facilities or term bank loans. Issuances of equity or debt in the capital markets, funds raised in the commercial paper markets and additional credit facilities may not, however, be available on acceptable terms.

Material Current and Long-term Cash Requirements. The liquidity and capital requirements of the Registrants are affected primarily by results of operations, capital expenditures, debt service requirements, tax payments, working capital needs and various regulatory actions. Capital expenditures are expected to be used for investment in infrastructure for electric and natural gas distribution operations. These capital expenditures are anticipated to maintain reliability and safety, increase resiliency and expand our systems through value-added projects. In addition to dividend payments on CenterPoint Energy’s Series A Preferred Stock and Common Stock, and in addition to interest payments on debt, the Registrants’ principal anticipated cash requirements for 2022 include the following:

<table><tr><td></td><td>CenterPoint Energy</td><td>CenterPoint Electric</td><td>CenterPoint Energy</td><td>CenterPoint Electric</td><td>CenterPoint Energy</td></tr><tr><td></td><td></td><td></td><td></td><td>(in millions)</td><td></td></tr><tr><td>Estimated capital expenditures</td><td>$ 3,490</td><td>$ 1,780</td><td>$ 1,233</td><td></td><td></td></tr><tr><td>Scheduled principal payments on Securitization Bonds</td><td>220</td><td>220</td><td>—</td><td></td><td></td></tr><tr><td>Maturing Houston Electric general mortgage bonds</td><td>300</td><td>300</td><td>—</td><td></td><td></td></tr><tr><td>Finance lease for mobile generation</td><td>496</td><td>496</td><td>—</td><td></td><td></td></tr></table>

The following table sets forth the Registrants’ estimates of the Registrants’ capital expenditures currently planned for projects for 2022 through 2026. See Note 18 to the consolidated financial statements for CenterPoint Energy’s actual capital expenditures by reportable segment for 2021.

February 2021 Winter Storm Event. In February 2021, portions of the United States experienced an extreme and unprecedented winter weather event resulting in corresponding electricity generation shortages, including in Texas, and natural gas shortages and increased prices of natural gas in the United States. Although CenterPoint Energy’s and CERC’s extraordinary costs from the increase in natural gas prices are subject to available natural gas cost recovery mechanisms in their jurisdictions (although timing of recovery is uncertain), until such amounts are ultimately recovered from customers, CenterPoint Energy and CERC will continue to incur increased finance-related costs, resulting in a significant use of cash. See “— Regulatory Matters — February 2021 Winter Storm Event” below and Note 7 to the consolidated financial statements.

Off-Balance Sheet Arrangements. Other than Houston Electric’s general mortgage bonds issued as collateral for tax-exempt long-term debt of CenterPoint Energy (see Note 14 to the consolidated financial statements) and short-term leases, the Registrants have no off-balance sheet arrangements.

## Indiana Electric CPCN (CenterPoint Energy)

On February 9, 2021, Indiana Electric entered into a BTA with a subsidiary of Capital Dynamics. Under the agreement, Capital Dynamics, with its partner Tenaska, contracted to build a 300 MW solar array in Posey County, Indiana through a special purpose entity, Posey Solar. Upon completion of construction, which is projected to be at the end of 2023. Indiana Electric will acquire Posey Solar and its solar array assets for a fixed purchase price. On February 23, 2021, Indiana Electric filed a CPCN with the IURC seeking approval to purchase the project. Indiana Electric also sought approval for a 100 MW solar PPA with Clenera LLC in Warrick County, Indiana. The request accounted for increased cost of debt related to this PPA, which provides equivalent equity return to offset imputed debt during the 25 year life of the PPA. A hearing was conducted on June 21, 2021. On October 27, 2021, the IURC issued an order approving the CPCN, authorizing Indiana Electric to purchase the Posey solar project through a BTA and approved recovery of costs via a levelized rate over the anticipated 35-year life. The IURC also approved the Warrick County solar PPA but denied the request to preemptively offset imputed debt in the PPA cost. The Posey solar project is expected to be in service by 2023. Due to rising cost for the project, caused in part by supply chain issues in the energy industry and the rising costs of commodities, we, along with Capital Dynamics, recently announced plans to downsize the project to approximately 200 MW. Indiana Electric collaboratively agreed to the scope change and is currently working through contract negotiations, contingent on further IURC review and approval.

On June 17, 2021 Indiana Electric filed a CPCN with the IURC seeking approval to construct two natural gas combustion turbines to replace portions of its existing coal-fired generation fleet. Indiana Electric has also requested depreciation expense and post in-service carrying costs to be deferred in a regulatory asset until the date Indiana South’s base rates include a return on and recovery of depreciation expense on the facility. A hearing was conducted on January 26 through 28, 2022. The estimated $334 million turbine facility would be constructed at the current site of the A.B. Brown power plant in Posey County, Indiana and would provide a combined output of 460 MW. Construction of the turbines will begin following receipt of necessary regulatory approvals by the IURC and FERC, which are anticipated in the second half of 2022 and first quarter 2023, respectively. The turbines are targeted to be operational in first quarter of 2025. Subject to IURC approval, recovery of the



proposed natural gas combustion turbines and regulatory asset will be requested in the next Indiana Electric rate case expected in 2023.

On August 25, 2021, Indiana Electric filed with the IURC seeking approval to purchase 185 MW of solar power, under a 15-year PPA, from Oriden LLC, which is developing a solar project in Vermillion County, Indiana, and 150 MW of solar power, under a 20-year PPA, from Origis Energy USA Inc., which is developing a solar project in Knox County, Indiana. Subject to necessary approvals, both solar arrays are expected to be in service by 2023.

## Indiana Electric Securitization of Planned Generation Retirements (CenterPoint Energy)

The State of Indiana has enacted legislation, Senate Bill 386, that would enable CenterPoint Energy to request approval from the IURC to securitize the remaining book value and removal costs associated with generating facilities to be retired in the next twenty-four months. The Governor of Indiana signed the legislation on April 19, 2021. CenterPoint Energy intends to seek securitization in the future associated with planned retirements of coal generation facilities in 2022.

## Subsidiary Restructuring

In July 2021, Indiana North and SIGECO filed petitions with the IURC for the approval of a new financial services agreement and the confirmation of Indiana North's financing authority, and final orders were issued by the IURC on December 28, 2021. VEDO filed a similar application with the PUCO in September 2021 and the PUCO issued an order on January 26, 2022 adopting recommendations by PUCO staff. CenterPoint Energy is evaluating the transfer of Indiana North and VEDO from VUHI to CERC in order to better align its organizational structure with management and financial reporting. Both the IURC and PUCO have approved the transaction. As a part of the restructuring, VUHI may approach certain of its debt holders with an offer to exchange existing VUHI debt for CERC debt. The orders allow the reissuance of existing debt of Indiana North and VEDO to CERC, to continue to amortize existing issuance expenses and discounts, and to treat any potential exchange fees as discounts to be amortized over the life of the debt. If CenterPoint Energy moves forward with the restructuring, including any VUHI debt exchanges, it is expected to be completed in 2022.

## Indiana South Base Rate Case (CenterPoint Energy)

On October 30, 2020, and as subsequently amended, Indiana South filed its base rate case with the IURC seeking approval for a revenue increase of approximately $29 million. This rate case filing is required under Indiana TDSIC statutory requirements before the completion of Indiana South’s capital expenditure program, approved in 2014 for investments starting in 2014 through 2020. The revenue increase is based upon a requested ROE of 10.15% and an overall after-tax rate of return of 5.99% on total rate base of approximately $469 million. Indiana South has utilized a projected test year, reflecting its 2021 budget as the basis for the revenue increase requested and proposes to implement rates in two phases. On April 23, 2021, a Stipulation and Settlement Agreement was filed resolving all issues in the case. The settlement recommended a revenue increase of $21 million based on a 9.7% ROE and an overall after-tax rate of return of 5.78% on total rate base of approximately $469 million. A settlement hearing was held on June 24, 2021. On October 6, 2021, the IURC issued an order approving the settlement. Phase one rates, reflecting actual plant-in-service and cost of capital through June 2021, became effective in October 2021 and phase two rates, reflecting actual plant-in-service and cost of capital through December 2021 with certain adjustments, will become effective in March 2022.

## Indiana North Base Rate Case (CenterPoint Energy)

On December 18, 2020, Indiana North filed its base rate case with the IURC seeking approval for a revenue increase of approximately $21 million. This rate case filing is required under Indiana TDSIC statutory requirements before the completion of Indiana North’s capital expenditure program, approved in 2014 for investments starting in 2014 through 2020. The revenue increase is based upon a requested ROE of 10.15% and an overall after-tax rate of return of 6.32% on total rate base of approximately $1,611 million. Indiana North has utilized a projected test year, reflecting its 2021 budget as the basis for the revenue increase requested and proposes to implement rates in two phases. On June 25, 2021, a Stipulation and Settlement Agreement was filed resolving all issues in the case. The settlement recommended a revenue decrease of $6 million based on a 9.8% ROE and an overall after-tax rate of return of 6.16% on total rate base of approximately $1,611 million. A settlement hearing was held August 6, 2021. On November 17, 2021, the IURC issued an order approving the settlement. Phase one rates, reflecting actual plant-in-service and cost of capital through June 2021, became effective in November 2021 and phase two rates, reflecting actual plant-in-service and cost of capital through December 2021 with certain adjustments, will become effective in March 2022.



In April 2017, Houston Electric submitted a proposal to ERCOT requesting its endorsement of the Freeport Area Master Plan, which included the Bailey to Jones Creek Project. On November 21, 2019, the PUCT issued its final approval of Houston Electric’s certificate of convenience and necessity application, based on an unopposed settlement agreement under which Houston Electric would construct the project at an estimated cost of approximately $483 million. Houston Electric commenced pre-construction activities on the project in 2019, began construction in 2021, and completed construction and energized the line ahead of schedule in November 2021. Certain residual clean-up activities will continue in 2022.

## Space City Solar Transmission Interconnection Project (CenterPoint Energy and Houston Electric)

On December 17, 2020, Houston Electric filed a CCN application with the PUCT for approval to build a 345 kV transmission line in Wharton County, Texas connecting the Hillje substation on Houston Electric's transmission system to the planned 610 MW Space City Solar Generation facility being developed by third-party developer EDF Renewables. Depending on the route ultimately approved by the PUCT, the estimated capital cost of the transmission line project ranges from approximately $23 million to $71 million. The actual capital costs of the project will depend on actual land acquisition costs, construction costs, and other factors in addition to route selection. In January 2021, Houston Electric executed a Standard Generation Interconnection Agreement for the Space City Solar Generation facility with EDF Renewables, which also provided security for the transmission line project in the form of a $23 million letter of credit, the amount of which is subject to change depending on the route approved. A hearing at the PUCT was held on June 28, 2021. On September 1, 2021, the administrative law judge issued a proposal for decision recommending a route that costs $25 million. The PUCT approved the proposal for decision at the November 18, 2021 open meeting and issued a final order on January 12, 2022. Houston Electric expects to complete construction and energization of the transmission line by the end of 2022.

## Texas Legislation (CenterPoint Energy and Houston Electric)

In addition to the legislative activity discussed above, the Texas legislature enacted the following in 2021:

Senate Bill 2 reforms the ERCOT board to be comprised of a total of eleven directors: three ex officio representatives, and eight members who are unaffiliated with any market participants. The three ex officio directors—the ERCOT CEO, the Public Counsel of the Office of Public Utility Counsel, and the PUCT Chair—serve on the board by virtue of their official position for as long as they hold that position. Two members are non-voting directors: the ERCOT CEO and the PUCT Chair. The other nine members are voting directors. The ERCOT board is currently comprised of the following members: Mr. Paul Foster (Chairman of ERCOT board), Mr. William Flores (Vice Chairman of ERCOT board), Mr. Carlos Aguilar, Mr. Zin Smati, Mr. John Swainson, Mr. Robert Flexon, Ms. Julie England, Ms. Peggy Heeg, Mr. Peter Lake (PUCT Chairman), Mr. Brad Jones (ERCOT Interim President & CEO), and Mr. Chris Ekoh (Public Counsel of the Office of Public Utility Counsel).

Senate Bill 3 establishes weatherization and other power grid requirements including the design and operation of a load management program for nonresidential customers during an energy emergency activation level 2 or higher event and the ability to recover the reasonable and necessary costs of the program.

Senate Bill 415 allows a TDU to seek prior PUCT approval to contract with a power generation company for a PUCT assigned proportional share of electric energy storage system at the distribution level and recover certain costs and a reasonable return on contract payments if contract terms satisfy relevant accounting standards for a capital lease or finance lease.

- House Bill 2483 allows a TDU to procure, own and operate, or jointly own with another TDU, transmission and distribution facilities with a lead time of at least six months that would aid in restoring power to the utility's distribution customers following a widespread outage, excluding storage equipment or facilities. Reasonable and necessary costs can be recovered using the rate of return on investment from the most recent base rate proceeding. Recovery of incremental operation and maintenance expenses and any return not recovered in a rate proceeding can be deferred until a future ratemaking proceeding. Additionally, a TDU may lease and operate facilities that provide temporary emergency electric energy to aid in restoring power to the utility's distribution customers during a widespread power outage. Leasing and operating costs can be recovered using the utility's rate of return from the most recent base rate proceeding and incremental operation and maintenance expenses can be deferred. The lease must be treated as a capital lease or finance lease for ratemaking purposes.

- Senate Bill 1281 removes the requirement for an electric utility to amend its CCN to construct a transmission line that connects existing transmission facilities to a substation or metering point if certain conditions are met and adds a customer benefit test into consideration. The bill also requires ERCOT to conduct biennial assessments of grid reliability in extreme weather scenarios.



Houston Electric continues to review the effects of the legislation and is working with the PUCT regarding proposed rulemakings and pursuing implementation of these items where applicable. For example, in 2021 Houston Electric entered into two leases for mobile generation: (1) a temporary short-term lease initially for 125 MW that expanded to 220 MW by December 31, 2021 and (2) a 7.5 year lease for up to 505 MW of mobile generation of which 125 MW was delivered as of December 31, 2021. As of December 31, 2021, CenterPoint Energy and Houston Electric intends to seek recovery in its DCRF of deferred costs and the applicable return under these lease agreements, approximating $200 million. These mobile generation leases will support resiliency in major weather events and were deployed during the restoration process for Hurricane Nicholas. See Note 21 to the consolidated financial statements.

In addition to these measures taken by Houston Electric to support system preparedness and reliability, the City of Houston recently launched the first-of-its-kind long-term strategic power resilience initiative called “Resilient Now.” In a joint effort, Houston Electric is working with the City of Houston to develop the Master Energy Plan for the city to help the community thrive through economic changes, digital transformation, and advancing environmental goals for the benefit of its communities. The Master Energy Plan could develop into capital opportunities for Houston Electric, including relating to infrastructure modernization, residential weatherization, and investments around electric vehicles infrastructure.

## Minnesota Base Rate Cases (CenterPoint Energy and CERC)

On October 28, 2019, CERC filed a general rate case with the MPUC seeking approval for a revenue increase of approximately $62 million with a projected test year ended December 31, 2020. The revenue increase is based upon a requested ROE of 10.15% and an overall after-tax rate of return of 7.41% on a total rate base of approximately $1,307 million. CERC implemented interim rates reflecting $53 million for natural gas used on and after January 1, 2020. In September 2020, a settlement that addressed all issues except the Inclusive Financing/TOB Financing proposal by the City of Minneapolis was signed by a majority of all parties and was filed with the Office of Administrative Hearings. A stipulation between the City of Minneapolis and CERC addressing the TOB proposal was filed on September 2, 2020. The settlement reflects a $39 million increase and was based on an overall after-tax rate of return of 6.86% and does not specify individual cost of capital components. On March 1, 2021, the MPUC issued a written final order approving the $39 million increase and rejected the TOB stipulation. The order also required CERC and the City of Minneapolis to submit a future filing to allow for further development of a potential TOB pilot program and additional or expanded low-income conservation improvement programs. A compliance filing was submitted on March 12, 2021 proposing a final rate implementation on June 1, 2021 and the interim refund occurring in June 2021, contingent on final MPUC approval. Pursuant to MPUC approval, final rates were implemented on June 1, 2021 and the interim rate refunds were applied to customer accounts starting on June 12, 2021.

On November 1, 2021, CERC filed a general rate case with the MPUC seeking approval for a revenue increase of approximately $67 million with a projected test year ended December 31, 2022. The revenue increase is based upon a requested ROE of 10.2% and an overall rate of return of 7.06% on a total rate base of approximately $1.8 billion. CERC requested that an interim rate increase of approximately $52 million be implemented January 1, 2022 while the rate case is litigated. An alternative request was also filed on November 1, 2021. The alternative request proposed a final rate increase of $40 million that would be implemented in the rate case on January 1, 2022, and offered: an increase in rates for plant investment only using the overall rate of return approved in the prior rate case, an asymmetrical capital true-up, extension of the recovery of gas costs incurred to serve customers in February 2021 from the then current 27 month mechanism to 63 months, an income tax rider, continuation of the existing property tax rider and continued deferral of COVID-19 incremental costs along with additional adjustments. On December 30, 2021, the MPUC issued a written order denying the alternative request but extended the amortization period for extraordinary gas costs to 63-months beginning on January 1, 2022. The MPUC also issued written orders on the general rate case filing which (1) accepted CERC's rate-increase application with a time for final determination of September 1, 2022, (2) authorized the implementation of interim rates on January 1, 2022, of $42 million based on an overall rate of return of 6.46%, and (3) referred the case to the Office of Administrative Hearings for a contested case proceeding. A procedural schedule has been set with intervenor testimony that was due on February 7, 2022, rebuttal testimony due on March 7, 2022, surrebuttal testimony due March 30, 2022, a hearing scheduled April 6, 2022 through April 8, 2022, the administrative law judge to issue a report on July 12, 2022 and the MPUC to issue an order in October 2022.

## Minnesota Legislation (CenterPoint Energy and CERC)

The Natural Gas Innovation Act was passed by the Minnesota legislature in June 2021 with bipartisan support. This law establishes a regulatory framework to enable the state’s investor-owned natural gas utilities to provide customers with access to renewable energy resources and innovative technologies, with the goal of reducing greenhouse gas emissions and advancing the



state’s clean energy future. Specifically, the Natural Gas Innovation Act allows a natural gas utility to submit an innovation plan for approval by the MPUC which could propose the use of renewable energy resources and innovative technologies such as:

• renewable natural gas (produces energy from organic materials such as wastewater, agricultural manure, food waste, agricultural or forest waste);

• renewable hydrogen gas (produces energy from water through electrolysis with renewable electricity such as solar);

• energy efficiency measures (avoids energy consumption in excess of the utility’s existing conservation programs); and

• innovative technologies (reduces or avoids greenhouse gas emissions using technologies such as carbon capture).

CERC expects to submit its first innovation plan to the MPUC in 2022. The maximum allowable cost for an innovation plan will start at 1.75% of the utility's revenue in the state and could increase to 4% by 2033, subject to review and approval by the MPUC.

## Rate Change Applications

The Registrants are routinely involved in rate change applications before state regulatory authorities. Those applications include general rate cases, where the entire cost of service of the utility is assessed and reset. In addition, Houston Electric is periodically involved in proceedings to adjust its capital tracking mechanisms (TCOS and DCRF) and annually files to adjust its EECRF.

## Greenhouse Gas Regulation and Compliance (CenterPoint Energy)

On August 3, 2015, the EPA released its CPP rule, which required a 32% reduction in carbon emissions from 2005 levels. The final rule was published in the Federal Register on October 23, 2015, and that action was immediately followed by litigation ultimately resulting in the U.S. Supreme Court staying implementation of the rule. On July 8, 2019, the EPA published the ACE rule, which (i) repealed the CPP rule; (ii) replaced the CPP rule with a program that requires states to implement a program of energy efficiency improvement targets for individual coal-fired electric generating units; and (iii) amended the implementing regulations for Section 111(d) of the Clean Air Act. On January 19, 2021, the majority of the ACE rule — including the CPP repeal, CPP replacement, and the timing-related portions of the Section 111(d) implementing rule — was struck down by the U.S. Court of Appeals for the D.C. Circuit and on October 29, 2021, the U.S. Supreme Court agreed to consider four petitions filed by various coal interests and a coalition of 19 states that seek review of the lower court’s decision vacating the ACE rule. CenterPoint Energy is currently unable to predict what a replacement rule for either the ACE rule or CPP would require.

The Biden administration recommitted the United States to the Paris Agreement, which can be expected to drive a renewed regulatory push to require further GHG emission reductions from the energy sector and proceeded to lead negotiations at the global climate conference in Glasgow, Scotland. On April 22, 2021, President Biden announced new goals of 50% reduction of economy-wide GHG emissions, and 100% carbon-free electricity by 2035, which formed the basis of the US commitments announced in Glasgow. In September 2021, CenterPoint Energy announced its new net zero emissions goals for both Scope 1 and Scope 2 emissions by 2035 as well as a goal to reduce Scope 3 emissions by 20% to 30% by 2035. Because Texas is an unregulated market, CenterPoint Energy’s Scope 2 estimates do not take into account Texas electric transmission and distribution assets in the line loss calculation and exclude emissions related to purchased power in Indiana between 2024 and 2026 as estimated. CenterPoint Energy’s Scope 3 estimates do not take into account the emissions of transport customers and emissions related to upstream extraction. These emission goals are expected to be used to position CenterPoint Energy to comply with anticipated future regulatory requirements from the current and future administrations to further reduce GHG emissions. CenterPoint Energy’s and CERC’s revenues, operating costs and capital requirements could be adversely affected as



a result of any regulatory action that would require installation of new control technologies or a modification of their operations or would have the effect of reducing the consumption of natural gas. For more information regarding CenterPoint Energy’s new net zero emission goals and the risks associated with them, see “Risk Factors — Risk Factors Affecting Our Businesses — CenterPoint Energy is subject to operational and financial risks...” In addition, the EPA has indicated that it intends to implement new regulations targeting reductions in methane emissions, which are likely to increase costs related to production, transmission and storage of natural gas. Houston Electric, in contrast to some electric utilities including Indiana Electric, does not generate electricity, other than leasing facilities that provide temporary emergency electric energy to aid in restoring power to distribution customers during certain widespread power outages as allowed by a new law enacted after the February 2021 Winter Storm Event, and thus is not directly exposed to the risk of high capital costs and regulatory uncertainties that face electric utilities that burn fossil fuels to generate electricity. CenterPoint Energy’s new net zero emissions goals are aligned with Indiana Electric’s generation transition plan and are expected to position Indiana Electric to comply with anticipated future regulatory requirements related to GHG emissions reductions. Nevertheless, Houston Electric’s and Indiana Electric’s revenues could be adversely affected to the extent any resulting regulatory action has the effect of reducing consumption of electricity by ultimate consumers within their respective service territories. Likewise, incentives to conserve energy or to use energy sources other than natural gas could result in a decrease in demand for the Registrants’ services. For example, Minnesota has enacted the Natural Gas Innovation Act that seeks to provide customers with access to renewable energy resources and innovative technologies, with the goal of reducing GHG emissions. Further, certain local government bodies have introduced or are considering requirements and/or incentives to reduce energy consumption by certain specified dates. For example, Minneapolis has adopted carbon emission reduction goals in an effort to decrease reliance on fossil gas. Additionally, cities in Minnesota within CenterPoint Energy’s Natural Gas operational footprint are considering initiatives to eliminate natural gas use in buildings and focus on electrification. Also, Minnesota cities may consider seeking legislative authority for the ability to enact voluntary enhanced energy standards for all development projects. These initiatives could have a significant impact on CenterPoint Energy and its operations, and this impact could increase if other cities and jurisdictions in its service area enact similar initiatives. Further, our third party suppliers, vendors and partners may also be impacted by climate change laws and regulations, which could impact CenterPoint Energy’s business by, among other things, causing permitting and construction delays, project cancellations or increased project costs passed on to CenterPoint Energy. Conversely, regulatory actions that effectively promote the consumption of natural gas because of its lower emissions characteristics would be expected to benefit CenterPoint Energy and CERC and their natural gas-related businesses. At this time, however, we cannot quantify the magnitude of the impacts from possible new regulatory actions related to GHG emissions, either positive or negative, on the Registrants’ businesses.

Compliance costs and other effects associated with climate change, reductions in GHG emissions and obtaining renewable energy sources remain uncertain. Although the amount of compliance costs remains uncertain, any new regulation or legislation relating to climate change will likely result in an increase in compliance costs. While the requirements of a federal or state rule remain uncertain, CenterPoint Energy will continue to monitor regulatory activity regarding GHG emission standards that may affect its business. Currently, CenterPoint Energy does not purchase carbon credits. In connection with its net zero emissions goals, CenterPoint Energy is expected to purchase carbon credits in the future; however, CenterPoint Energy does not currently expect the number of credits, or cost for those credits, to be material.

## Climate Change Trends and Uncertainties

As a result of increased awareness regarding climate change, coupled with adverse economic conditions, availability of alternative energy sources, including private solar, microturbines, fuel cells, energy-efficient buildings and energy storage devices, and new regulations restricting emissions, including potential regulations of methane emissions, some consumers and companies may use less energy, meet their own energy needs through alternative energy sources or avoid expansions of their facilities, including natural gas facilities, resulting in less demand for the Registrants' services. As these technologies become a more cost-competitive option over time, whether through cost effectiveness or government incentives and subsidies, certain customers may choose to meet their own energy needs and subsequently decrease usage of the Registrants' systems and services, which may result in, among other things, Indiana Electric's generating facilities becoming less competitive and economical. Further, evolving investor sentiment related to the use of fossil fuels and initiatives to restrict continued production of fossil fuels have had significant impacts on CenterPoint Energy's electric generation and natural gas businesses. For example, because Indiana Electric's current generating facilities substantially rely on coal for their operations, certain financial institutions choose not to participate in CenterPoint Energy's financing arrangements. Conversely, demand for the Registrants' services may increase as a result of customer changes in response to climate change. For example, as the utilization of electric vehicles increases, demand for electricity may increase, resulting in increased usage of CenterPoint Energy's systems and services. Any negative opinions with respect to CenterPoint Energy's environmental practices or its ability to meet the



challenges posed by climate change formed by regulators, customers, investors, legislators or other stakeholders could harm its reputation.

To address these developments, CenterPoint Energy announced its new net zero emissions goals for both Scope 1 and Scope 2 emissions by 2035. In June of 2020, Indiana Electric identified a preferred generation resource in its most recent IRP submitted to the IURC that aligns with its new net zero emission goals and includes the replacement of 730 MW of coal-fired generation facilities with a significant portion comprised of renewables, including solar and wind, supported by dispatchable natural gas combustion turbines, including a pipeline to serve such natural gas generation, as well as storage. Additionally, as reflected in its 10-year capital plan announced in September 2021, CenterPoint Energy anticipates spending over $3 billion in clean energy investments and enablement, which may be used to support, among other things, renewable energy generation and electric vehicle expansion. CenterPoint Energy believes its planned investments in renewable energy generation and corresponding planned reduction in its GHG emissions as part of its newly adopted net zero emissions goals support global efforts to reduce the impacts of climate change. For more information regarding CenterPoint Energy’s new net zero emission goals and the risks associated with them, see “Risk Factors — Risk Factors Affecting Our Businesses — CenterPoint Energy is subject to operational and financial risks...”

To the extent climate changes result in warmer temperatures in the Registrants’ service territories, financial results from the Registrants’ businesses could be adversely impacted. For example, CenterPoint Energy’s and CERC’s Natural Gas could be adversely affected through lower natural gas sales. On the other hand, warmer temperatures in CenterPoint Energy’s and Houston Electric’s electric service territory may increase revenues from transmission and distribution and generation through increased demand for electricity used for cooling. Another possible result of climate change is more frequent and more severe weather events, such as hurricanes, tornadoes and flooding, including such storms as the February 2021 Winter Storm Event. Since many of the Registrants’ facilities are located along or near the Texas gulf coast, increased or more severe hurricanes or tornadoes could increase costs to repair damaged facilities and restore service to customers. CenterPoint Energy’s recently announced 10-year capital plan includes capital expenditures to maintain reliability and safety and increase resiliency of its systems as climate change may result in more frequent significant weather events. Houston Electric does not own or operate any electric generation facilities other than, since September 2021, leasing facilities that provide temporary emergency electric energy to aid in restoring power to distribution customers during certain widespread power outages as allowed by a new law enacted after the February 2021 Winter Storm Event. Houston Electric transmits and distributes to customers of REPs electric power that the REPs obtain from power generation facilities owned by third parties. To the extent adverse weather conditions affect the Registrants’ suppliers, results from their energy delivery businesses may suffer. For example, in Texas, the February 2021 Winter Storm Event caused an electricity generation shortage that was severely disruptive to Houston Electric’s service territory and the wholesale generation market and also caused a reduction in available natural gas capacity. When the Registrants cannot deliver electricity or natural gas to customers, or customers cannot receive services, the Registrants’ financial results can be impacted by lost revenues, and they generally must seek approval from regulators to recover restoration costs. To the extent the Registrants are unable to recover those costs, or if higher rates resulting from recovery of such costs result in reduced demand for services, the Registrants’ future financial results may be adversely impacted. Further, as the intensity and frequency of significant weather events continues, it may impact our ability to secure cost-efficient insurance.

## Other Matters

## Credit Facilities

The Registrants may draw on their respective revolving credit facilities from time to time to provide funds used for general corporate and limited liability company purposes, including to backstop CenterPoint Energy’s and CERC’s commercial paper programs. The facilities may also be utilized to obtain letters of credit. For further details related to the Registrants’ revolving credit facilities, please see Note 14 to the consolidated financial statements.

Based on the consolidated debt to capitalization covenant in the Registrants’ revolving credit facilities, the Registrants would have been permitted to utilize the full capacity of such revolving credit facilities, which aggregated approximately $4 billion as of December 31, 2021.



As of February 15, 2022, the Registrants had the following revolving credit facilities and utilization of such facilities:

<table><tr><td rowspan="2">Registrant</td><td rowspan="2">Size of Facility</td><td colspan="4">Amount Utilized as of February 15, 2022</td><td rowspan="2">Weighted Average Interest Rate</td><td rowspan="2">Termination Date</td></tr><tr><td>Loans</td><td>Letters of Credit</td><td>Commercial Paper</td></tr><tr><td></td><td></td><td>(in millions)</td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>CenterPoint Energy</td><td>$ 2,400</td><td>$ —</td><td>$ 11</td><td>$ 710</td><td>0.23%</td><td>February 4, 2024</td><td></td></tr><tr><td>CenterPoint Energy (1)</td><td>400</td><td>—</td><td>—</td><td>264</td><td>0.22%</td><td>February 4, 2024</td><td></td></tr><tr><td>Houston Electric</td><td>300</td><td>—</td><td>—</td><td>—</td><td>—%</td><td>February 4, 2024</td><td></td></tr><tr><td>CERC</td><td>900</td><td>—</td><td>—</td><td>100</td><td>0.19%</td><td>February 4, 2024</td><td></td></tr><tr><td>Total</td><td>$ 4,000</td><td>$ —</td><td>$ 11</td><td>$ 1,074</td><td></td><td></td><td></td></tr></table>

(1) The credit facility was issued by VUHI and is guaranteed by SIGECO, Indiana Gas and VEDO.

Borrowings under each of the revolving credit facilities are subject to customary terms and conditions. However, there is no requirement that the borrower makes representations prior to borrowing as to the absence of material adverse changes or litigation that could be expected to have a material adverse effect. Borrowings under each of the revolving credit facilities are subject to acceleration upon the occurrence of events of default that we consider customary. The revolving credit facilities also provide for customary fees, including commitment fees, administrative agent fees, fees in respect of letters of credit and other fees. In each of the revolving credit facilities, the spread to LIBOR and the commitment fees fluctuate based on the borrower's credit rating. Each of the Registrant's credit facilities provide for a mechanism to replace LIBOR with possible alternative benchmarks upon certain benchmark replacement events. The borrowers are currently in compliance with the various business and financial covenants in the four revolving credit facilities.

## Long-term Debt

For detailed information about the Registrants’ debt issuances in 2021, see Note 14 to the consolidated financial statements.

## Securities Registered with the SEC

On May 29, 2020, the Registrants filed a joint shelf registration statement with the SEC registering indeterminate principal amounts of Houston Electric’s general mortgage bonds, CERC Corp.’s senior debt securities and CenterPoint Energy’s senior debt securities and junior subordinated debt securities and an indeterminate number of shares of Common Stock, shares of preferred stock, depositary shares, as well as stock purchase contracts and equity units. The joint shelf registration statement will expire on May 29, 2023. For information related to the Registrants’ debt and equity security issuances in 2021, see Notes 13 and 14 to the consolidated financial statements.

## Temporary Investments

As of February 15, 2022, the Registrants had no temporary investments.

## Money Pool

The Registrants participate in a money pool through which they and certain of their subsidiaries can borrow or invest on a short-term basis. Funding needs are aggregated and external borrowing or investing is based on the net cash position. The net funding requirements of the CenterPoint Energy money pool are expected to be met with borrowings under CenterPoint Energy’s revolving credit facility or the sale of CenterPoint Energy’s commercial paper. The net funding requirements of the CERC money pool are expected to be met with borrowings under CERC’s revolving credit facility or the sale of CERC’s commercial paper. The money pool may not provide sufficient funds to meet the Registrants’ cash needs.

The table below summarizes CenterPoint Energy money pool activity by Registrant as of February 15, 2022:

## Impact on Liquidity of a Downgrade in Credit Ratings

The interest rate on borrowings under the Registrants’ credit facilities is based on their respective credit ratings. As of February 15, 2022, Moody’s, S&P and Fitch had assigned the following credit ratings to senior debt of the Registrants:

<table><tr><td rowspan="2">Registrant</td><td rowspan="2">Borrower/Instrument</td><td colspan="2">Moody’s</td><td colspan="2">S&amp;P</td><td colspan="2">Fitch</td></tr><tr><td>Rating</td><td>Outlook (1)</td><td>Rating</td><td>Outlook (2)</td><td>Rating</td><td>Outlook (3)</td></tr><tr><td>CenterPoint Energy</td><td>CenterPoint Energy Senior Unsecured Debt</td><td>Baa2</td><td>Stable</td><td>BBB</td><td>Stable</td><td>BBB</td><td>Stable</td></tr><tr><td>CenterPoint Energy</td><td>Vectren Corp.

(1) A Moody’s rating outlook is an opinion regarding the likely direction of an issuer’s rating over the medium term.

(2) An S&P outlook assesses the potential direction of a long-term credit rating over the intermediate to longer term.

(3) A Fitch rating outlook indicates the direction a rating is likely to move over a one- to two-year period.

The Registrants cannot assure that the ratings set forth above will remain in effect for any given period of time or that one or more of these ratings will not be lowered or withdrawn entirely by a rating agency. The Registrants note that these credit ratings are included for informational purposes and are not recommendations to buy, sell or hold the Registrants’ securities and may be revised or withdrawn at any time by the rating agency. Each rating should be evaluated independently of any other rating. Any future reduction or withdrawal of one or more of the Registrants’ credit ratings could have a material adverse impact on the Registrants’ ability to obtain short- and long-term financing, the cost of such financings and the execution of the Registrants’ commercial strategies.

A decline in credit ratings could increase borrowing costs under the Registrants’ revolving credit facilities. If the Registrants’ credit ratings had been downgraded one notch by S&P and Moody’s from the ratings that existed as of December 31, 2021, the impact on the borrowing costs under the four revolving credit facilities would have been insignificant. A decline in credit ratings would also increase the interest rate on long-term debt to be issued in the capital markets and could negatively impact the Registrants’ ability to complete capital market transactions and to access the commercial paper market. Additionally, a decline in credit ratings could increase cash collateral requirements and reduce earnings of CenterPoint Energy’s and CERC’s Natural Gas reportable segments.

Pipeline tariffs and contracts typically provide that if the credit ratings of a shipper or the shipper’s guarantor drop below a threshold level, which is generally investment grade ratings from both Moody’s and S&P, cash or other collateral may be demanded from the shipper in an amount equal to the sum of three months’ charges for pipeline services plus the unrecovered cost of any lateral built for such shipper. If the credit ratings of CERC Corp. decline below the applicable threshold levels, CERC might need to provide cash or other collateral of as much as $213 million as of December 31, 2021. The amount of collateral will depend on seasonal variations in transportation levels.

## ZENS and Securities Related to ZENS (CenterPoint Energy)

If CenterPoint Energy’s creditworthiness were to drop such that ZENS holders thought its liquidity was adversely affected or the market for the ZENS were to become illiquid, some ZENS holders might decide to exchange their ZENS for cash. Funds for the payment of cash upon exchange could be obtained from the sale of the shares of ZENS-Related Securities that CenterPoint Energy owns or from other sources. CenterPoint Energy owns shares of ZENS-Related Securities equal to approximately 100% of the reference shares used to calculate its obligation to the holders of the ZENS. ZENS exchanges result in a cash outflow because tax deferrals related to the ZENS and shares of ZENS-Related Securities would typically cease when ZENS are exchanged or otherwise retired and shares of ZENS-Related Securities are sold. The ultimate tax liability related to the ZENS and ZENS-Related Securities continues to increase by the amount of the tax benefit realized each year, and there could be a significant cash outflow when the taxes are paid as a result of the retirement or exchange of the ZENS. If all ZENS had been exchanged for cash on December 31, 2021, deferred taxes of approximately $539 million would have been payable in



2021. If all the ZENS-Related Securities had been sold on December 31, 2021, capital gains taxes of approximately $146 million would have been payable in 2021. For additional information about ZENS, see Note 12 to the consolidated financial statements.

## Cross Defaults

Under each of CenterPoint Energy’s (including VUHI’s), Houston Electric’s and CERC’s respective revolving credit facilities, a payment default on, or a non-payment default that permits acceleration of, any indebtedness for borrowed money and certain other specified types of obligations (including guarantees) exceeding $125 million by the borrower or any of their respective significant subsidiaries will cause a default under such borrower’s respective credit facility or term loan agreement. A default by CenterPoint Energy would not trigger a default under its subsidiaries’ debt instruments or revolving credit facilities.

## Possible Acquisitions, Divestitures and Joint Ventures

From time to time, the Registrants consider the acquisition or the disposition of assets or businesses or possible joint ventures, strategic initiatives or other joint ownership arrangements with respect to assets or businesses. Any determination to take action in this regard will be based on market conditions and opportunities existing at the time, and accordingly, the timing, size or success of any efforts and the associated potential capital commitments are unpredictable. The Registrants may seek to fund all or part of any such efforts with proceeds from debt and/or equity issuances. Debt or equity financing may not, however, be available to the Registrants at that time due to a variety of events, including, among others, maintenance of our credit ratings, industry conditions, general economic conditions, market conditions and market perceptions. As announced in September 2021, CenterPoint Energy plans to increase its planned capital expenditures in its Electric and Natural Gas businesses to support rate base growth and may explore asset sales in addition to the recently completed sale of its Natural Gas businesses located in Arkansas and Oklahoma as a means to efficiently finance a portion of such increased capital expenditures. On January 10, 2022, CERC Corp. completed the sale of its Arkansas and Oklahoma regulated natural gas LDC businesses. For further information, see Notes 4 and 22 to the consolidated financial statements.

On December 2, 2021, the Enable Merger closed and, as a result, CenterPoint Energy received Energy Transfer Common Units and Energy Transfer Series G Preferred Units. Subsequent to the closing of the Enable Merger, in December 2021, CenterPoint Energy sold 150 million of the Energy Transfer Common Units (inclusive of the Energy Transfer Common Units sold pursuant to the Forward Sale Agreement) and half of the Energy Transfer Series G Preferred Units it received in the Enable Merger. CenterPoint Energy has announced plans to dispose of all of its interests in Energy Transfer by the end of 2022. CenterPoint Energy may not realize any or all of the anticipated strategic, financial, operational or other benefits from any disposition or reduction of its investment in Energy Transfer. There can be no assurances that any further disposal of Energy Transfer Common Units or Energy Transfer Series G Preferred Units will be completed. Any disposal of such securities may involve significant costs and expenses, including in connection with any public offering, a significant underwriting discount. For information regarding the Enable Merger, see Notes 4, 11 and 12 to the consolidated financial statements.

## Hedging of Interest Expense for Future Debt Issuances

From time to time, the Registrants may enter into interest rate agreements to hedge, in part, volatility in the U.S. treasury rates by reducing variability in cash flows related to interest payments. For further information, see Note 9(a) to the consolidated financial statements.

## Weather Hedge (CenterPoint Energy and CERC)

CenterPoint Energy and CERC have historically entered into partial weather hedges for certain Natural Gas jurisdictions and electric operations' Texas service territory to mitigate the impact of fluctuations from normal weather. CenterPoint Energy and CERC remain exposed to some weather risk as a result of the partial hedges. CenterPoint Energy and CERC did not enter into any weather hedges during the year ended December 31, 2021. For more information about weather hedges, see Note 9(a) to the consolidated financial statements.

## Collection of Receivables from REPs (CenterPoint Energy and Houston Electric)

Houston Electric’s receivables from the distribution of electricity are collected from REPs that supply the electricity Houston Electric distributes to their customers. Before conducting business, a REP must register with the PUCT and must meet certain financial qualifications. Nevertheless, adverse economic conditions, structural problems in the market served by ERCOT



or financial difficulties of one or more REPs could impair the ability of these REPs to pay for Houston Electric’s services or could cause them to delay such payments. Houston Electric depends on these REPs to remit payments on a timely basis, and any delay or default in payment by REPs could adversely affect Houston Electric’s cash flows. In the event of a REP’s default, Houston Electric’s tariff provides a number of remedies, including the option for Houston Electric to request that the PUCT suspend or revoke the certification of the REP. Applicable regulatory provisions require that customers be shifted to another REP or a provider of last resort if a REP cannot make timely payments. However, Houston Electric remains at risk for payments related to services provided prior to the shift to the replacement REP or the provider of last resort. If a REP were unable to meet its obligations, it could consider, among various options, restructuring under the bankruptcy laws, in which event such REP might seek to avoid honoring its obligations and claims might be made against Houston Electric involving payments it had received from such REP. If a REP were to file for bankruptcy, Houston Electric may not be successful in recovering accrued receivables owed by such REP that are unpaid as of the date the REP filed for bankruptcy. However, PUCT regulations authorize utilities, such as Houston Electric, to defer bad debts resulting from defaults by REPs for recovery in future rate cases, subject to a review of reasonableness and necessity.

## Other Factors that Could Affect Cash Requirements

In addition to the above factors, the Registrants’ liquidity and capital resources could also be negatively affected by:

- cash collateral requirements that could exist in connection with certain contracts, including weather hedging arrangements, and natural gas purchases, natural gas price and natural gas storage activities of CenterPoint Energy’s and CERC’s Natural Gas reportable segment;

• reductions in the cash distributions we receive from Energy Transfer;

- acceleration of payment dates on certain gas supply contracts, under certain circumstances, as a result of increased natural gas prices, and concentration of natural gas suppliers (CenterPoint Energy and CERC);

• increased costs related to the acquisition of natural gas (CenterPoint Energy and CERC);

- increases in interest expense in connection with debt refinancings and borrowings under credit facilities or term loans or the use of alternative sources of financings due to the effects of COVID-19 on capital and other financial markets;

• various legislative or regulatory actions;

• incremental collateral, if any, that may be required due to regulation of derivatives (CenterPoint Energy);

- the ability of REPs, including REP affiliates of NRG and Vistra Energy Corp., to satisfy their obligations to CenterPoint Energy and Houston Electric, including the negative impact on such ability related to COVID-19 and the February 2021 Winter Storm Event;

- slower customer payments and increased write-offs of receivables due to higher natural gas prices, changing economic conditions, COVID-19 or the February 2021 Winter Storm Event (CenterPoint Energy and CERC);

• the satisfaction of any obligations pursuant to guarantees;

• the outcome of litigation, including litigation related to the February 2021 Winter Storm Event;

• contributions to pension and postretirement benefit plans;

- restoration costs and revenue losses resulting from future natural disasters such as hurricanes and the timing of recovery of such restoration costs; and

• various other risks identified in “Risk Factors” in Item 1A of Part I of this report.

## Certain Contractual Limits on Our Ability to Issue Securities and Borrow Money

Certain provisions in certain note purchase agreements relating to debt issued by VUHI have the effect of restricting the amount of additional first mortgage bonds issued by SIGECO. Additionally, such note purchase agreements would restrict the securitization (as enabled by Senate Bill 386 as enacted by the State of Indiana) that CenterPoint Energy intends to seek in 2022 of remaining book value and removal costs associated with generating facilities to be retired by Indiana Electric. For information about the total debt to capitalization financial covenants in the Registrants’ and certain of CenterPoint Energy’s subsidiaries’ revolving credit facilities, see Note 14 to the consolidated financial statements.

## CRITICAL ACCOUNTING POLICIES

A critical accounting policy is one that is both important to the presentation of the Registrants’ financial condition and results of operations and requires management to make difficult, subjective or complex accounting estimates. An accounting estimate is an approximation made by management of a financial statement element, item or account in the financial statements. Accounting estimates in the Registrants’ historical consolidated financial statements measure the effects of past business transactions or events, or the present status of an asset or liability. The accounting estimates described below require the Registrants to make assumptions about matters that are highly uncertain at the time the estimate is made. Additionally, different estimates that the Registrants could have used or changes in an accounting estimate that are reasonably likely to occur could



have a material impact on the presentation of their financial condition, results of operations or cash flows. The circumstances that make these judgments difficult, subjective and/or complex have to do with the need to make estimates about the effect of matters that are inherently uncertain. Estimates and assumptions about future events and their effects cannot be predicted with certainty. The Registrants base their estimates on historical experience and on various other assumptions that they believe to be reasonable under the circumstances, the results of which form the basis for making judgments. These estimates may change as new events occur, as more experience is acquired, as additional information is obtained and as the Registrants' operating environment changes. The Registrants' significant accounting policies are discussed in Note 2 to the consolidated financial statements. The Registrants believe the following accounting policies involve the application of critical accounting estimates. Accordingly, these accounting estimates have been reviewed and discussed with the Audit Committee of CenterPoint Energy's Board of Directors.

## Accounting for Rate Regulation

Accounting guidance for regulated operations provides that rate-regulated entities account for and report assets and liabilities consistent with the recovery of those incurred costs in rates if the rates established are designed to recover the costs of providing the regulated service and if the competitive environment makes it probable that such rates can be charged and collected. CenterPoint Energy, for its Electric and Natural Gas reportable segments, Houston Electric and CERC apply this accounting guidance. Certain expenses and revenues subject to utility regulation or rate determination normally reflected in income are deferred on the balance sheet as regulatory assets or liabilities and are recognized in income as the related amounts are included in service rates and recovered from or refunded to customers. Regulatory assets and liabilities are recorded when it is probable that these items will be recovered or reflected in future rates. Determining probability requires significant judgment on the part of management and includes, but is not limited to, consideration of testimony presented in regulatory hearings, proposed regulatory decisions, final regulatory orders and the strength or status of applications for rehearing or state court appeals. If events were to occur that would make the recovery of these assets and liabilities no longer probable, the Registrants would be required to write off or write down these regulatory assets and liabilities. For further detail on the Registrants' regulatory assets and liabilities, see Note 7 to the consolidated financial statements.

## Impairment of Long-Lived Assets, Including Identifiable Intangibles, Goodwill, and Equity Method Investments

The Registrants review the carrying value of long-lived assets, including identifiable intangibles, goodwill, equity method investments, and investments without a readily determinable fair value whenever events or changes in circumstances indicate that such carrying values may not be recoverable, and at least annually, goodwill is tested for impairment as required by accounting guidance for goodwill and other intangible assets. Unforeseen events, changes in market conditions, and probable regulatory disallowances, where applicable, could have a material effect on the value of long-lived assets, including intangibles, goodwill, equity method investments, and investments without a readily determinable fair value due to changes in observable or estimated market value, future cash flows, interest rate, and regulatory matters could result in an impairment charge. The Registrants recorded no impairments to long-lived assets, including intangibles, goodwill, or equity method investments during 2021 and 2019. During 2020, CenterPoint Energy recognized equity method investment impairment losses as discussed further in Note 11 to the consolidated financial statements and goodwill impairment losses as discussed further in Notes 6 and 10 to the consolidated financial statements.

Fair value is the amount at which an asset, liability or business could be bought or sold in a current transaction between willing parties and may be estimated using a number of techniques, including quoted market prices or valuations by third parties, present value techniques based on estimates of cash flows, or multiples of earnings or revenue performance measures. The fair value could be different using different estimates and assumptions in these valuation techniques.

Fair value measurements require significant judgment and unobservable inputs, including (i) projected timing and amount of future cash flows, which factor in planned growth initiatives, (ii) the regulatory environment, as applicable, and (iii) discount rates reflecting risk inherent in the future market prices. Determining the discount rates for the non-rate regulated businesses requires the estimation of the appropriate company specific risk premiums for those non-rate regulated businesses based on evaluation of industry and entity-specific risks, which includes expectations about future market or economic conditions existing on the date of the impairment test. Changes in these assumptions could have a significant impact on results of the impairment tests.

## Annual goodwill impairment test

CenterPoint Energy and CERC completed their 2021 annual goodwill impairment test during the third quarter of 2021 and determined, based on an income approach or a weighted combination of income and market approaches, that no goodwill



impairment charge was required for any reporting unit. The fair values of each reporting unit significantly exceeded the carrying value of the reporting unit.

Although no goodwill impairment resulted from the 2021 annual test, an interim goodwill impairment test could be triggered by the following: actual earnings results that are materially lower than expected, significant adverse changes in the operating environment, an increase in the discount rate, changes in other key assumptions which require judgment and are forward looking in nature, if CenterPoint Energy’s market capitalization falls below book value for an extended period of time, or events affecting a reporting unit such as a contemplated disposal of all or part of a reporting unit.

## Assets Held for Sale and Discontinued Operations

Generally, a long-lived asset to be sold is classified as held for sale in the period in which management, with approval from the Board of Directors, as applicable, commits to a plan to sell, and a sale is expected to be completed within one year. The Registrants record assets and liabilities held for sale, or the disposal group, at the lower of their carrying value or their estimated fair value less cost to sell. If a disposal group reflects a component of a reporting unit and meets the definition of a business, the goodwill within that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. Goodwill is not allocated to a portion of a reporting unit that does not meet the definition of a business. A disposal group that meets the held for sale criteria and also represents a strategic shift to the Registrant is also reflected as discontinued operations on the Statements of Consolidated Income, and prior periods are recast to reflect the earnings or losses from such businesses as income from discontinued operations, net of tax.

During the year ended December 31, 2021, as described further in Note 4 to the consolidated financial statements, certain assets and liabilities representing a business met the held for sale criteria. As a result, goodwill attributable to the natural gas reporting unit of $398 million and $144 million at CenterPoint Energy and CERC, respectively, was deemed attributable to assets held for sale as of December 31, 2021. Neither CenterPoint Energy nor CERC recognized any gains or losses upon classification of held for sale, including impairments of goodwill, during the year ended December 31, 2021.

Fair value is the amount at which an asset, liability or business could be bought or sold in a current transaction between willing parties and may be estimated using a number of techniques, including quoted market prices, present value techniques based on estimates of cash flows, or multiples of earnings or revenue performance measures. The fair value could be different if different estimates and assumptions in these valuation techniques were applied.

Fair value measurements require significant judgment and often unobservable inputs, including (i) projected timing and amount of future cash flows, which factor in planned growth initiatives, (ii) the regulatory environment, as applicable, and (iii) discount rates reflecting risk inherent in the future market prices. Changes in these assumptions could have a significant impact on the resulting fair value.

CenterPoint Energy and CERC used a market approach consisting of the contractual sales price adjusted for estimated working capital and other contractual purchase price adjustments to determine fair value of the businesses classified as held for sale. The fair value of the retained businesses within the natural gas reporting unit was estimated based on a weighted combination of income and market approaches, consistent with the methodology used in the 2021 and 2020 annual goodwill impairment tests. A third-party valuation specialist was utilized to determine the key assumptions used in the estimate of fair value of the retained natural gas reporting unit as of December 31, 2021. The fair value of the retained natural gas reporting unit at CenterPoint Energy and CERC significantly exceeded the carrying value of the retained businesses within that reporting unit immediately after classifying the Arkansas and Oklahoma Natural Gas businesses as held for sale.

For further information, see Note 4 to the consolidated financial statements.

## Unbilled Revenues

Revenues related to electricity delivery and natural gas sales and services are generally recognized upon delivery to customers. However, the determination of deliveries to individual customers is based on the reading of their meters, which is performed on a systematic basis throughout the month either electronically through AMS meter communications or manual readings. At the end of each month, deliveries to non-AMS customers since the date of the last meter reading are estimated and the corresponding unbilled revenue is estimated. Information regarding deliveries to AMS customers after the last billing is obtained from actual AMS meter usage data. Unbilled electricity delivery revenue is estimated each month based on actual AMS meter data, daily supply volumes and applicable rates. Unbilled natural gas sales are estimated based on estimated



purchased gas volumes, estimated lost and unaccounted for gas and tariffed rates in effect. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting estimates.

## Pension and Other Retirement Plans

CenterPoint Energy sponsors pension and other retirement plans in various forms covering all employees who meet eligibility requirements. CenterPoint Energy uses several statistical and other factors that attempt to anticipate future events in calculating the expense and liability related to its plans. These factors include assumptions about the discount rate, expected return on plan assets and rate of future compensation increases as estimated by management, within certain guidelines. In addition, CenterPoint Energy’s actuarial consultants use subjective factors such as withdrawal and mortality rates. The actuarial assumptions used may differ materially from actual results due to changing market and economic conditions, higher or lower withdrawal rates or longer or shorter life spans of participants. These differences may result in a significant impact to the amount of pension and other retirement plans expense recorded. Please read “— Other Significant Matters — Pension Plans” for further discussion.

## NEW ACCOUNTING PRONOUNCEMENTS

See Note 2(u) to the consolidated financial statements, incorporated herein by reference, for a discussion of new accounting pronouncements that affect the Registrants.

## OTHER SIGNIFICANT MATTERS

Pension Plans (CenterPoint Energy). As discussed in Note 8(b) to the consolidated financial statements, CenterPoint Energy maintains non-contributory qualified defined benefit pension plans covering eligible employees. Employer contributions for the qualified plans are based on actuarial computations that establish the minimum contribution required under ERISA and the maximum deductible contribution for income tax purposes.

Under the terms of CenterPoint Energy’s pension plans, it reserves the right to change, modify or terminate the plan. CenterPoint Energy’s funding policy is to review amounts annually and contribute an amount at least equal to the minimum contribution required under ERISA.

Additionally, CenterPoint Energy maintains unfunded non-qualified benefit restoration plans that allows participants to receive the benefits to which they would have been entitled under the non-contributory qualified pension plan except for the federally mandated limits on qualified plan benefits or on the level of compensation on which qualified plan benefits may be calculated.

CenterPoint Energy’s funding requirements and employer contributions for the years ended December 31, 2021, 2020 and 2019 were as follows:

<table><tr><td rowspan="3">CenterPoint Energy</td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2021</td><td colspan="2">2020</td><td>2019</td></tr><tr><td colspan="4">(in millions)</td></tr><tr><td>Minimum funding requirements for qualified pension plans</td><td>$ —</td><td>$ 76</td><td>$ 86</td><td></td></tr><tr><td>Employer contributions to the qualified pension plans</td><td>53</td><td>76</td><td>86</td><td></td></tr><tr><td>Employer contributions to the non-qualified benefit restoration plans</td><td>8</td><td>10</td><td>23</td><td></td></tr></table>

Although CenterPoint Energy’s minimum contribution requirement to the qualified pension plans in 2022 is zero, it expects to make contributions aggregating up to $50 million. CenterPoint Energy expects to make contributions aggregating approximately $7 million to the non-qualified benefit restoration plans in 2022.

Changes in pension obligations and assets may not be immediately recognized as pension expense in CenterPoint Energy’s Statements of Consolidated Income, but generally are recognized in future years over the remaining average service period of plan participants. As such, significant portions of pension expense recorded in any period may not reflect the actual level of benefit payments provided to plan participants.

As the sponsor of a plan, CenterPoint Energy is required to (a) recognize on its Consolidated Balance Sheet an asset for the plan’s over-funded status or a liability for the plan’s under-funded status, (b) measure a plan’s assets and obligations as of the



end of the fiscal year and (c) recognize changes in the funded status of the plans in the year that changes occur through adjustments to other comprehensive income and, when related to its rate-regulated utilities with recoverability of cost, to regulatory assets.

The projected benefit obligation for all defined benefit pension plans was $2.3 billion and $2.5 billion as of December 31, 2021 and 2020, respectively.

As of December 31, 2021, the projected benefit obligation exceeded the market value of plan assets of CenterPoint Energy’s pension plans by $226 million. Changes in interest rates or the market values of the securities held by the plan during 2022 could materially, positively or negatively, change the funded status and affect the level of pension expense and required contributions.

Houston Electric and CERC participate in CenterPoint Energy’s qualified and non-qualified pension plans covering substantially all employees. Pension cost by Registrant were as follows:

<table><tr><td rowspan="3"></td><td colspan="12">Year Ended December 31,</td></tr><tr><td colspan="3">2021</td><td colspan="3">2020</td><td colspan="3">2019</td><td rowspan="2">CERC</td><td rowspan="2">CERC</td><td rowspan="2">CERC</td></tr><tr><td>CenterPoint Energy</td><td>Houston Electric</td><td>CERC</td><td>CenterPoint Energy</td><td>Houston Electric</td><td>CERC</td><td>CenterPoint Energy</td><td>CenterPoint Energy</td><td>Houston Electric</td></tr><tr><td>Pension cost</td><td>$ 69</td><td>$ 34</td><td>$ 27</td><td>$ 49</td><td>$ 19</td><td>$ 20</td><td>$ 93</td><td>$ 40</td><td>$ 35</td><td></td><td></td><td></td></tr></table>

The calculation of pension cost and related liabilities requires the use of assumptions. Changes in these assumptions can result in different expense and liability amounts, and future actual experience can differ from the assumptions. Two of the most critical assumptions are the expected long-term rate of return on plan assets and the assumed discount rate.

As of December 31, 2021, CenterPoint Energy’s qualified pension plans had an expected long-term rate of return on plan assets of 5.00% rate, which is the same rate assumed as of December 31, 2020. The expected rate of return assumption was developed using the targeted asset allocation of our plans and the expected return for each asset class. CenterPoint Energy regularly reviews its actual asset allocation and periodically rebalances plan assets to reduce volatility and better match plan assets and liabilities.

As of December 31, 2021, the projected benefit obligation was calculated assuming a discount rate of 2.80%, which is 0.35% higher than the 2.45% discount rate assumed as of December 31, 2020. The discount rate was determined by reviewing yields on high-quality bonds that receive one of the two highest ratings given by a recognized rating agency and the expected duration of pension obligations specific to the characteristics of CenterPoint Energy’s plans.

CenterPoint Energy’s actuarially determined pension and other postemployment cost for 2021 and 2020 that is greater or less than the amounts being recovered through rates in the majority of Texas jurisdictions is deferred as a regulatory asset or liability, respectively. Pension cost for 2022, including the nonqualified benefit restoration plan, is estimated to be $22 million before applicable regulatory deferrals and capitalization, based on an expected return on plan assets of 5.00% and a discount rate of 2.80% as of December 31, 2021. If the expected return assumption were lowered by 0.50% from 5.00% to 4.50%, 2022 pension cost would increase by approximately $10 million.

As of December 31, 2021, the pension plans projected benefit obligation, including the unfunded nonqualified pension plans, exceeded plan assets by $226 million. If the discount rate were lowered by 0.50% from 2.80% to 2.30%, the assumption change would increase CenterPoint Energy’s projected benefit obligation by approximately $118 million and decrease its 2022 pension cost by approximately $5 million. The expected reduction in pension cost due to the decrease in discount rate is a result of the expected correlation between the reduced interest rate and appreciation of fixed income assets in pension plans with significantly more fixed income instruments than equity instruments. In addition, the assumption change would impact CenterPoint Energy’s Consolidated Balance Sheets by increasing the regulatory asset recorded as of December 31, 2021 by $100 million and would result in a charge to comprehensive income in 2021 of $14 million, net of tax of $4 million, due to the increase in the projected benefit obligation.

Future changes in plan asset returns, assumed discount rates and various other factors related to the pension plans will impact CenterPoint Energy’s future pension expense and liabilities. CenterPoint Energy cannot predict with certainty what these factors will be in the future.



## Item 7A. Quantitative and Qualitative Disclosures About Market Risk

## Impact of Changes in Interest Rates, Equity Prices and Energy Commodity Prices

The Registrants are exposed to various market risks. These risks arise from transactions entered into in the normal course of business and are inherent in the Registrants' consolidated financial statements. Most of the revenues and income from the Registrants' business activities are affected by market risks. Categories of market risk include exposure to commodity prices through non-trading activities, interest rates and equity prices. A description of each market risk is set forth below:

• Interest rate risk primarily results from exposures to changes in the level of borrowings and changes in interest rates.

• Equity price risk results from exposures to changes in prices of individual equity securities (CenterPoint Energy).

- Commodity price risk results from exposures to price volatilities of commodities, such as natural gas, NGLs and other energy commodities (CenterPoint Energy).

Management has established comprehensive risk management policies to monitor and manage these market risks.

## Interest Rate Risk

As of December 31, 2021, the Registrants had outstanding long-term debt and lease obligations and CenterPoint Energy had obligations under its ZENS that subject them to the risk of loss associated with movements in market interest rates.

CenterPoint Energy’s floating rate obligations aggregated $4.5 billion and $2.4 billion as of December 31, 2021 and 2020, respectively. If the floating interest rates were to increase by 10% from December 31, 2021 rates, CenterPoint Energy’s combined interest expense would increase by approximately $2 million annually.

Houston Electric did not have any floating rate obligations as of either December 31, 2021 or 2020.

CERC’s floating rate obligations aggregated $1.9 billion and $347 million as of December 31, 2021 and 2020, respectively. If the floating interest rates were to increase by 10% from December 31, 2021 rates, CERC’s combined interest expense would increase by approximately $1 million annually.

As of December 31, 2021 and 2020, CenterPoint Energy had outstanding fixed-rate debt (excluding indexed debt securities) aggregating $11.7 billion and $11.1 billion, respectively, in principal amount and having a fair value of $13.0 billion and $12.9 billion, respectively. Because these instruments are fixed-rate, they do not expose CenterPoint Energy to the risk of loss in earnings due to changes in market interest rates. However, the fair value of these instruments would increase by approximately $359 million if interest rates were to decline by 10% from their levels as of December 31, 2021.

As of December 31, 2021 and 2020, Houston Electric had outstanding fixed-rate debt aggregating $5.5 billion and $5.1 billion, respectively, in principal amount and having a fair value of approximately $6.3 billion and $6.0 billion, respectively. Because these instruments are fixed-rate, they do not expose Houston Electric to the risk of loss in earnings due to changes in market interest rates. However, the fair value of these instruments would increase by approximately $214 million if interest rates were to decline by 10% from their levels as of December 31, 2021.

As of December 31, 2021 and 2020, CERC had outstanding fixed-rate debt aggregating $2.5 billion and $2.1 billion, respectively, in principal amount and having a fair value of $2.8 billion and $2.5 billion, respectively. Because these instruments are fixed-rate, they do not expose CERC to the risk of loss in earnings due to changes in market interest rates. However, the fair value of these instruments would increase by approximately $71 million if interest rates were to decline by 10% from their levels at December 31, 2021.

In general, such an increase in fair value would impact earnings and cash flows only if the Registrants were to reacquire all or a portion of these instruments in the open market prior to their maturity.

As discussed in Note 12 to the consolidated financial statements, the ZENS obligation is bifurcated into a debt component and a derivative component. The debt component of $10 million at December 31, 2021 was a fixed-rate obligation and, therefore, did not expose CenterPoint Energy to the risk of loss in earnings due to changes in market interest rates. However, the fair value of the debt component would increase by approximately $1 million if interest rates were to decline by 10% from levels at December 31, 2021. Changes in the fair value of the derivative component, a $903 million recorded liability at December 31, 2021, are recorded in CenterPoint Energy’s Statements of Consolidated Income and, therefore, it is exposed to changes in the fair value of the derivative component as a result of changes in the underlying risk-free interest rate. If the risk-



free interest rate were to increase by 10% from December 31, 2021 levels, the fair value of the derivative component liability would decrease by approximately $1 million, which would be recorded as an unrealized gain in CenterPoint Energy’s Statements of Consolidated Income.

## Equity Market Value Risk (CenterPoint Energy)

CenterPoint Energy is exposed to equity market value risk through its ownership of 10.2 million shares of AT&T Common and 0.9 million shares of Charter Common, which CenterPoint Energy holds to facilitate its ability to meet its obligations under the ZENS and through its ownership of 51 million shares of Energy Transfer Common Units and 0.2 million shares of Energy Transfer Series G Preferred Units. See Note 12 to the consolidated financial statements for a discussion of CenterPoint Energy’s ZENS obligation and the Energy Transfer Common Units and Energy Transfer Series G Preferred Units that CenterPoint Energy holds. Changes in the fair value of the ZENS-Related Securities held by CenterPoint Energy are expected to substantially offset changes in the fair value of the derivative component of the ZENS. A decrease of 10% from the December 31, 2021 aggregate market value of these shares would result in a net loss of less than $1 million, which would be recorded as a loss on debt securities in CenterPoint Energy’s Statements of Consolidated Income.

## Commodity Price Risk From Non-Trading Activities (CenterPoint Energy)

CenterPoint Energy’s regulated operations in Indiana have limited exposure to commodity price risk for transactions involving purchases and sales of natural gas, coal and purchased power for the benefit of retail customers due to current state regulations, which, subject to compliance with those regulations, allow for recovery of the cost of such purchases through natural gas and fuel cost adjustment mechanisms. CenterPoint Energy’s utility natural gas operations in Indiana have regulatory authority to lock in pricing for up to 50% of annual natural gas purchases using arrangements with an original term of up to 10 years. This authority has been utilized to secure fixed price natural gas using both physical purchases and financial derivatives. As of December 31, 2021, the recorded fair value of non-trading energy derivative assets was $14 million for CenterPoint Energy’s utility natural gas operations in Indiana, which is offset by a regulatory asset.

Although CenterPoint Energy’s regulated operations are exposed to limited commodity price risk, natural gas and coal prices have other effects on working capital requirements, interest costs, and some level of price-sensitivity in volumes sold or delivered. Constructive regulatory orders, such as those authorizing lost margin recovery, other innovative rate designs and recovery of unaccounted for natural gas and other natural gas-related expenses, also mitigate the effect natural gas costs may have on CenterPoint Energy’s financial condition. In 2008, the PUCO approved an exit of the merchant function in CenterPoint Energy’s Ohio natural gas service territory, allowing Ohio customers to purchase substantially all natural gas directly from retail marketers rather than from CenterPoint Energy.

We have audited the accompanying consolidated balance sheets of CenterPoint Energy, Inc. and subsidiaries (the "Company") as of December 31, 2021 and 2020, the related statements of consolidated income, comprehensive income, changes in equity, and cash flows, for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2022, expressed an unqualified opinion on the Company's internal control over financial reporting.

## Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

## Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

## Impact of Rate Regulation on the Financial Statements — Refer to Notes 2 and 7 to the financial statements

## Critical Audit Matter Description

The Company is subject to rate regulation by regulators and commissions in various jurisdictions (collectively, the "Commissions") that have jurisdiction with respect to the rates of electric and gas transmission and distribution companies in those jurisdictions. Management has determined its regulated operations meet the requirements under accounting principles generally accepted in the United States of America to prepare its financial statements applying the specialized rules to account for the effects of cost-based rate regulation. Accounting for the economics of rate regulation impacts multiple financial statement line items and disclosures, such as property, plant, and equipment, net; prepaid expenses and other current assets; regulatory assets and liabilities; utility revenues and expenses; operation and maintenance expense; depreciation and amortization expense; and income tax expense.

The Company’s rates are subject to regulatory rate-setting processes by the Commissions. Rates are determined and approved in regulatory proceedings based on an analysis of the Company’s costs to provide utility service and a return on, and recovery of, the Company’s investment in the utility business. Regulatory decisions can have an impact on the recovery of costs, the rate of return earned on investment, and the timing and amount of assets to be recovered by rates. The regulation of rates is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital. Decisions to be made by the Commissions in



the future will impact the accounting for regulated operations, including decisions about the amount of allowable costs and return on invested capital included in rates and any refunds that may be required. While the Company has indicated it expects to recover costs from customers through regulated rates, there is a risk that the Commissions will not approve: (1) full recovery of the costs of providing utility service, or (2) full recovery of all amounts invested in the utility business and a reasonable return on that investment.

We identified the impact of rate regulation as a critical audit matter due to the significant judgments made by management to support its assertions about affected account balances and disclosures and the high degree of subjectivity involved in assessing the impact of future regulatory actions on the financial statements. Management judgments include assessing the likelihood of (1) recovery in future rates of incurred costs, (2) a disallowance of capital investments made by the Company and (3) refunds to customers. Given that certain of management’s accounting judgments are based on assumptions about the outcome of future decisions by the Commissions, auditing these judgments required specialized knowledge of accounting for rate regulation and the rate setting process.

## How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the uncertainty of future decisions by the Commissions included the following, among others:

- We tested the effectiveness of management’s controls over the evaluation of the likelihood of (1) the recovery in future rates of costs incurred and deferred as regulatory assets, and (2) refund or future reductions in rates that should be reported as regulatory liabilities. We also tested the effectiveness of management’s controls over the initial recognition of amounts as regulatory assets or liabilities; and the monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates or of a future reduction in rates.

- We evaluated the Company’s disclosures related to the impacts of rate regulation, including the balances recorded and regulatory developments.

- We read relevant regulatory orders issued by the Commissions for the Company and other public utilities, regulatory statutes, interpretations, procedural memorandums, filings made by intervenors, and other publicly available information to assess the likelihood of recovery in future rates or of a future reduction in rates based on precedents of the Commissions’ treatment of similar costs under similar circumstances. We evaluated the external information and compared to management’s recorded regulatory asset and liability balances for completeness.

- For regulatory matters in process, we inspected the Company’s filings with the Commissions and the filings with the Commissions by intervenors that may impact the Company’s future rates, for any evidence that might contradict management’s assertions.

- We evaluated management’s assertion that no indicators of impairment were identified in connection with the Company’s property, plant, and equipment. We inspected the capital projects budget and inquired of management to identify projects that are designed to replace assets that may be retired prior to the end of the useful life. We inspected minutes of the board of directors and regulatory orders and other filings with the Commissions to identify any evidence that may contradict management’s assertion regarding probability of a disallowance of long-lived assets.

- We evaluated regulatory filings for any evidence that intervenors are challenging full recovery of the cost of any capital projects and inquired of management to assess whether capitalized costs are probable of disallowance.

- We obtained an analysis from management and letters from internal and external legal counsel, as appropriate, regarding probability of recovery for regulatory assets or refund or future reduction in rates for regulatory liabilities not yet addressed in a regulatory order to assess management’s assertion that amounts are probable of recovery or a future reduction in rates.

# REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Member of

CenterPoint Energy Houston Electric, LLC

## Opinion on the Financial Statements

We have audited the accompanying balance sheets of CenterPoint Energy Houston Electric, LLC and subsidiaries (an indirect wholly-owned subsidiary of CenterPoint Energy, Inc.) (the "Company") as of December 31, 2021 and 2020, the related statements of consolidated income, comprehensive income, changes in equity, and cash flows, for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

## Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

## Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

## Impact of Rate Regulation on the Financial Statements — Refer to Note 2 and 7 to the financial statements

## Critical Audit Matter Description

The Company is subject to rate regulation by the Public Utility Commission of Texas (“PUCT”), which has jurisdiction with respect to the rates charged by electric transmission and distribution companies in Texas. Management has determined it meets the requirements under accounting principles generally accepted in the United States of America to prepare its financial statements applying the specialized rules to account for the effects of cost-based rate regulation. Accounting for the economics of rate regulation impacts multiple financial statement line items and disclosures, such as property, plant, and equipment, net; regulatory assets and liabilities; utility revenues; operation and maintenance expense; depreciation and amortization expense; and income tax expense.

The Company’s rates are subject to regulatory rate-setting processes by the PUCT. Rates are determined and approved in regulatory proceedings based on an analysis of the Company’s costs to provide utility service and a return on, and recovery of, the Company’s investment in the utility business. Regulatory decisions can have an impact on the recovery of costs, the rate of return earned on investment, and the timing and amount of assets to be recovered by rates. The PUCT’s regulation of rates is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital. Decisions to be made by the PUCT in the future will impact the accounting for regulated operations, including decisions about the amount of allowable costs and return on invested capital included in rates and any refunds that may be required. While the Company has indicated it expects to recover costs



from customers through regulated rates, there is a risk that the PUCT will not approve: (1) full recovery of the costs of providing utility service, or (2) full recovery of all amounts invested in the utility business and a reasonable return on that investment.

We identified the impact of rate regulation as a critical audit matter due to the significant judgments made by management to support its assertions about affected account balances and disclosures and the high degree of subjectivity involved in assessing the impact of future regulatory actions on the financial statements. Management judgments include assessing the likelihood of (1) recovery in future rates of incurred costs, (2) a disallowance capital of investments made by the Company, and (3) refunds to customers. Given that certain of management’s accounting judgments are based on assumptions about the outcome of future decisions by the PUCT, auditing these judgments required specialized knowledge of accounting for rate regulation and the rate setting process.

## How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the uncertainty of future decisions by the PUCT included the following, among others:

- We tested the effectiveness of management’s controls over the evaluation of the likelihood of (1) the recovery in future rates of costs incurred and deferred as regulatory assets, and (2) refunds or future reductions in rates that should be reported as regulatory liabilities. We also tested the effectiveness of management’s controls over the initial recognition of amounts as regulatory assets or liabilities; and the monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates or of a future reduction in rates.

- We evaluated the Company’s disclosures related to the impacts of rate regulation, including the balances recorded and regulatory developments.

- We read relevant regulatory orders issued by the PUCT for the Company, regulatory statutes, interpretations, procedural memorandums, filings made by intervenors, and other publicly available information to assess the likelihood of recovery in future rates or of a future reduction in rates based on precedents of the PUCT’s treatment of similar costs under similar circumstances. We evaluated the external information and compared to management’s recorded regulatory asset and liability balances for completeness.

- For regulatory matters in process, we inspected the Company’s filings with the PUCT and the filings with the PUCT by intervenors that may impact the Company’s future rates, for any evidence that might contradict management’s assertions.

- We evaluated management’s assertion that no indicators of impairment were identified in connection with the Company’s property, plant, and equipment. We inspected the capital projects budget and inquired of management to identify projects that are designed to replace assets that may be retired prior to the end of the useful life. We inspected minutes of the board of directors and regulatory orders and other filings with the PUCT to identify any evidence that may contradict management’s assertion regarding probability of a disallowance of long-lived assets.

- We evaluated regulatory filings for any evidence that intervenors are challenging full recovery of the cost of any capital projects and inquired of management to assess whether capitalized costs are probable of disallowance.

- We obtained an analysis from management and letters from internal and external legal counsel, as appropriate, regarding probability of recovery for regulatory assets or refund or future reduction in rates for regulatory liabilities not yet addressed in a regulatory order to assess management’s assertion that amounts are probable of recovery or a future reduction in rates.

# REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholder of CenterPoint Energy Resources Corp.

## Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of CenterPoint Energy Resources Corp. and subsidiaries (an indirect wholly-owned subsidiary of CenterPoint Energy, Inc.) (the "Company") as of December 31, 2021 and 2020, the related statements of consolidated income, comprehensive income, changes in equity, and cash flows, for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

## Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

## Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

## Impact of Rate Regulation on the Financial Statements — Refer to Note 2 and 7 to the financial statements

## Critical Audit Matter Description

The Company is subject to rate regulation by regulators and commissions in various jurisdictions (collectively, the “Commissions”) that have jurisdiction with respect to the rates of electric and gas transmission and distribution companies in those jurisdictions. Management has determined it meets the requirements under accounting principles generally accepted in the United States of America to prepare its financial statements applying the specialized rules to account for the effects of cost-based rate regulation. Accounting for the economics of rate regulation impacts multiple financial statement line items and disclosures, such as property, plant, and equipment, net; prepaid expenses and other current assets; regulatory assets and liabilities; utility revenues and expenses; operation and maintenance expense; depreciation and amortization expense; and income tax expense.

The Company’s rates are subject to regulatory rate-setting processes by the Commissions. Rates are determined and approved in regulatory proceedings based on an analysis of the Company’s costs to provide utility service and a return on, and recovery of, the Company’s investment in the utility business. Regulatory decisions can have an impact on the recovery of costs, the rate of return earned on investment, and the timing and amount of assets to be recovered by rates. The Commissions’ regulation of rates is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital. Decisions to be made by the Commissions in the future will impact the accounting for regulated operations, including decisions about the amount of allowable



costs and return on invested capital included in rates and any refunds that may be required. While the Company has indicated it expects to recover costs from customers through regulated rates, there is a risk that the Commissions will not approve: (1) full recovery of the costs of providing utility service, or (2) full recovery of all amounts invested in the utility business and a reasonable return on that investment.

We identified the impact of rate regulation as a critical audit matter due to the significant judgments made by management to support its assertions about affected account balances and disclosures and the high degree of subjectivity involved in assessing the impact of future regulatory actions on the financial statements. Management judgments include assessing the likelihood of (1) recovery in future rates of incurred costs, (2) a disallowance of capital investments made by the Company and (3) refunds to customers. Given that certain of management’s accounting judgments are based on assumptions about the outcome of future decisions by the Commissions, auditing these judgments required specialized knowledge of accounting for rate regulation and the rate setting process.

## How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the uncertainty of future decisions by the Commissions included the following, among others:

- We tested the effectiveness of management’s controls over the evaluation of the likelihood of (1) the recovery in future rates of costs incurred and deferred as regulatory assets, and (2) refunds or future reductions in rates that should be reported as regulatory liabilities. We also tested the effectiveness of management’s controls over the initial recognition of amounts as regulatory assets or liabilities; and the monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates or of a future reduction in rates.

- We evaluated the Company’s disclosures related to the impacts of rate regulation, including the balances recorded and regulatory developments.

- We read relevant regulatory orders issued by the Commissions for the Company and other public utilities, regulatory statutes, interpretations, procedural memorandums, filings made by intervenors, and other publicly available information to assess the likelihood of recovery in future rates or of a future reduction in rates based on precedents of the Commissions’ treatment of similar costs under similar circumstances. We evaluated the external information and compared to management’s recorded regulatory asset and liability balances for completeness.

- For regulatory matters in process, we inspected the Company’s filings with the Commissions and the filings with the Commissions by intervenors that may impact the Company’s future rates, for any evidence that might contradict management’s assertions.

- We evaluated management’s assertion that no indicators of impairment were identified in connection with the Company’s property, plant, and equipment. We inspected the capital projects budget and inquired of management to identify projects that are designed to replace assets that may be retired prior to the end of the useful life. We inspected minutes of the board of directors and regulatory orders and other filings with the Commissions to identify any evidence that may contradict management’s assertion regarding probability of a disallowance of long-lived assets.

- We evaluated regulatory filings for any evidence that intervenors are challenging full recovery of the cost of any capital projects and inquired of management to assess whether capitalized costs are probable of disallowance.

- We obtained an analysis from management and letters from internal and external legal counsel, as appropriate, regarding probability of recovery for regulatory assets or refund or future reduction in rates for regulatory liabilities not yet addressed in a regulatory order to assess management’s assertion that amounts are probable of recovery or a future reduction in rates.

# CENTERPOINT ENERGY, INC. AND SUBSIDIARIES
CENTERPOINT ENERGY HOUSTON ELECTRIC, LLC AND SUBSIDIARIES
CENTERPOINT ENERGY RESOURCES CORP. AND SUBSIDIARIES

## COMBINED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

## (1) Background

General. This combined Form 10-K is filed separately by three registrants: CenterPoint Energy, Inc., CenterPoint Energy Houston Electric, LLC and CenterPoint Energy Resources Corp. Information contained herein relating to any individual registrant is filed by such registrant solely on its own behalf. Each registrant makes no representation as to information relating exclusively to the other Registrants or the subsidiaries of CenterPoint Energy other than itself or its subsidiaries.

Except as discussed in Note 14 to the Registrants’ Consolidated Financial Statements, no registrant has an obligation in respect of any other Registrant’s debt securities, and holders of such debt securities should not consider the financial resources or results of operations of any Registrant other than the obligor in making a decision with respect to such securities.

Included in this combined Form 10-K are the Financial Statements of CenterPoint Energy, Houston Electric and CERC, which are referred to collectively as the Registrants. The Combined Notes to the Consolidated Financial Statements apply to all Registrants and specific references to Houston Electric and CERC herein also pertain to CenterPoint Energy, unless otherwise indicated.

Background. CenterPoint Energy, Inc. is a public utility holding company. As of December 31, 2021, CenterPoint Energy’s operating subsidiaries were as follows:

- Houston Electric owns and operates electric transmission and distribution facilities in the Texas gulf coast area that includes the city of Houston; and

- CERC Corp. (i) owns and operates natural gas distribution systems in six states and (ii) owns and operates permanent pipeline connections through interconnects with various interstate and intrastate pipeline companies through CEIP.

• Vectren holds three public utilities through its wholly-owned subsidiary, VUHI, a public utility holding company:

Indiana Gas provides energy delivery services to natural gas customers located in central and southern Indiana;

SIGECO provides energy delivery services to electric and natural gas customers located in and near Evansville in southwestern Indiana and owns and operates electric generation assets to serve its electric customers and optimizes those assets in the wholesale power market; and

VEDO provides energy delivery services to natural gas customers located in and near Dayton in west-central Ohio.

- Vectren performs non-utility activities through Energy Systems Group, which provides energy performance contracting and sustainable infrastructure services, such as renewables, distributed generation and combined heat and power projects.

For a description of CenterPoint Energy’s reportable segments, see Note 18. Houston Electric consists of a single reportable segment, Houston Electric T&D and CERC consists of a single reportable segment, Natural Gas.

Held for Sale and Discontinued Operations. On January 10, 2022, CERC Corp. completed the sale of its Arkansas and Oklahoma Natural Gas businesses. For additional information regarding held for sale, discontinued operations and divestitures, see Note 4.



## (2) Summary of Significant Accounting Policies

## (a) Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

## (b) Principles of Consolidation

The accounts of the Registrants and their wholly-owned and majority-owned and controlled subsidiaries are included in the consolidated financial statements. All intercompany transactions and balances are eliminated in consolidation, except as described below.

Businesses within the Infrastructure Services Disposal Group provided underground pipeline construction and repair services for customers that included Natural Gas utilities. In accordance with consolidation guidance in ASC 980—Regulated Operations, costs incurred by Natural Gas utilities for these pipeline construction and repair services were not eliminated in consolidation when capitalized and included in rate base by the Natural Gas utility. On February 3, 2020, CenterPoint Energy, through its subsidiary VUSI, entered into the Securities Purchase Agreement to sell the Infrastructure Services Disposal Group. The transaction closed on April 9, 2020. For further information, see Note 4.

As of December 31, 2021, CenterPoint Energy and Houston Electric had VIEs consisting of the Bond Companies, which are consolidated. The consolidated VIEs are wholly-owned, bankruptcy remote special purpose entities that were formed solely for the purpose of securitizing transition and system restoration related property. Creditors of CenterPoint Energy and Houston Electric have no recourse to any assets or revenues of the Bond Companies. The bonds issued by these VIEs are payable only from and secured by transition and system restoration property and the bondholders have no recourse to the general credit of CenterPoint Energy or Houston Electric.

## (c) Equity Method and Investments without a Readily Determinable Fair Value (CenterPoint Energy)

CenterPoint Energy uses the equity method for investments in entities when it exercises significant influence, does not have control and is not considered the primary beneficiary, if applicable. Generally, equity investments in limited partnerships with interest greater than approximately 3-5% is accounted for under the equity method.

Under the equity method, CenterPoint Energy adjusts its investments each period for contributions made, distributions received, respective shares of comprehensive income and amortization of basis differences, as appropriate. CenterPoint Energy evaluates its equity method investments for impairment when events or changes in circumstances indicate there is a loss in value of the investment that is other than a temporary decline.

CenterPoint Energy considers distributions received from equity method investments which do not exceed cumulative equity in earnings subsequent to the date of investment to be a return on investment and classifies these distributions as operating activities in its Statements of Consolidated Cash Flows. CenterPoint Energy considers distributions received from equity method investments in excess of cumulative equity in earnings subsequent to the date of investment to be a return of investment and classifies these distributions as investing activities in its Statements of Consolidated Cash Flows.

Investments without a readily determinable fair value will be measured at cost, less impairment, plus or minus observable prices changes of an identical or similar investment of the same issuer.

## (d) Revenues

The Registrants record revenue for electricity delivery and natural gas sales and services under the accrual method and these revenues are recognized upon delivery to customers. Electricity deliveries not billed by month-end are accrued based on actual AMS/AMI data, supply volumes, estimated line loss and applicable tariff rates. Natural gas sales not billed by month-end are accrued based upon estimated purchased gas volumes, estimated lost and unaccounted for gas and currently effective tariff rates. For further discussion, see Note 5.



## (e) MISO Transactions

Indiana Electric is a member of the MISO. MISO-related purchase and sale transactions are recorded using settlement information provided by the MISO. These purchase and sale transactions are accounted for on at least a net hourly position, meaning net purchases within that interval are recorded on CenterPoint Energy’s Statements of Consolidated Income in Utility natural gas, fuel and purchased power, and net sales within that interval are recorded on CenterPoint Energy’s Statements of Consolidated Income in Utility revenues. On occasion, prior period transactions are resettled outside the routine process due to a change in the MISO’s tariff or a material interpretation thereof. Expenses associated with resettlements are recorded once the resettlement is probable and the resettlement amount can be estimated. Revenues associated with resettlements are recognized when the amount is determinable and collectability is reasonably assured.

## (f) Guarantees

CenterPoint Energy recognizes guarantee obligations at fair value. CenterPoint Energy discloses parent company guarantees of a subsidiary’s obligation when that guarantee results in the exposure of a material obligation of the parent company even if the probability of fulfilling such obligation is considered remote. See Note 16(c) and (d).

## (g) Long-lived Assets, Goodwill and Intangibles

The Registrants record property, plant and equipment at historical cost and expense repair and maintenance costs as incurred.

The Registrants periodically evaluate long-lived assets, including property, plant and equipment, and specifically identifiable intangibles subject to amortization, when events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. For rate regulated businesses, recoverability of long-lived assets is assessed by determining if a capital disallowance from a regulator is probable through monitoring the outcome of rate cases and other proceedings. For non-rate regulated businesses, recoverability is assessed based on an estimate of undiscounted cash flows attributable to the assets compared to the carrying value of the assets. No long-lived asset or intangible asset impairments were recorded in 2021, 2020 or 2019.

CenterPoint Energy and CERC perform goodwill impairment tests at least annually and evaluate goodwill when events or changes in circumstances indicate that its carrying value may not be recoverable. CenterPoint Energy and CERC recognize a goodwill impairment by the amount a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill within that reporting unit. CenterPoint Energy includes deferred tax assets and liabilities within its reporting unit’s carrying value for the purposes of annual and interim impairment tests, regardless of whether the estimated fair value reflects the disposition of such assets and liabilities. For further information about the goodwill impairment tests during 2021, see Note 6.

## (h) Assets Held for Sale and Discontinued Operations

Generally, a long-lived asset to be sold is classified as held for sale in the period in which management, with approval from the Board of Directors, as applicable, commits to a plan to sell and a sale is expected to be completed within one year. The Registrants record assets and liabilities held for sale at the lower of their carrying value or their estimated fair value less cost to sell. If the disposal group reflects a component of a reporting unit and meets the definition of a business, the goodwill within that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. Goodwill is not allocated to a portion of a reporting unit that does not meet the definition of a business. A disposal group that meets the held for sale criteria and also represents a strategic shift to the Registrant, is also reflected as discontinued operations on the Statements of Consolidated Income, and prior periods are recast to reflect the earnings or losses from such businesses as income from discontinued operations, net of tax.

## (i) Regulatory Assets and Liabilities

The Registrants apply the guidance for accounting for regulated operations within the Electric reportable segment and the Natural Gas reportable segment. The Registrants’ rate-regulated subsidiaries may collect revenues subject to refund pending final determination in rate proceedings. In connection with such revenues, estimated rate refund liabilities are recorded which reflect management’s current judgment of the ultimate outcomes of the proceedings.



The Registrants’ rate-regulated businesses recognize removal costs as a component of depreciation expense in accordance with regulatory treatment. In addition, a portion of the amount of removal costs collected from customers that relate to AROs has been reflected as an asset retirement liability in accordance with accounting guidance for AROs.

For further detail on the Registrants’ regulatory assets and liabilities, see Note 7.

## (j) Depreciation and Amortization Expense

The Registrants compute depreciation and amortization using the straight-line method based on economic lives or regulatory-mandated recovery periods. Amortization expense includes amortization of certain regulatory assets and other intangibles.

## (k) Capitalization of Interest and AFUDC

The Registrants capitalize interest and AFUDC as a component of projects under construction and amortize it over the assets’ estimated useful lives once the assets are placed in service. AFUDC represents the composite interest cost of borrowed funds and a reasonable return on the equity funds used for construction for subsidiaries that apply the guidance for accounting for regulated operations. Although AFUDC increases both utility plant and earnings, it is realized in cash when the assets are included in rates.

(1) Included in Interest and other finance charges on the Registrants' respective Statements of Consolidated Income, inclusive of $16 million, $13 million and $21 million of debt post in-service carrying costs on property, plant and equipment, primarily in Indiana, deferred into a regulatory asset in the years ended December 31, 2021, 2020 and 2019, respectively.

(2) Included in Other Income (Expense) on the Registrants' respective Statements of Consolidated Income.

## (l) Income Taxes

Houston Electric and CERC are included in CenterPoint Energy’s U.S. federal consolidated income tax return. Houston Electric and CERC report their income tax provision on a separate entity basis pursuant to a tax sharing agreement with CenterPoint Energy. Current federal and certain state income taxes are payable to or receivable from CenterPoint Energy.

The Registrants use the asset and liability method of accounting for deferred income taxes. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. A valuation allowance is established against deferred tax assets for which management believes realization is not considered to be more likely than not. The Registrants recognize interest and penalties as a component of income tax expense (benefit), as applicable, in their respective Statements of Consolidated Income. CenterPoint Energy reports the income tax provision associated with its interest in Enable in income tax expense (benefit) in its Statements of Consolidated Income.

To the extent certain EDIT of the Registrants’ rate-regulated subsidiaries may be recoverable or payable through future rates, regulatory assets and liabilities have been recorded, respectively. See Note 15 for further discussion.

The Registrants use the portfolio approach to recognize income tax effects on other comprehensive income from accumulated other comprehensive income.

Investment tax credits are deferred and amortized to income over the approximate lives of the related property.



## (m) Accounts Receivable and Allowance for Credit Losses

Accounts receivable are recorded at the invoiced amount and do not bear interest. Management reviews historical write-offs, current available information, and reasonable and supportable forecasts to estimate and establish allowance for credit losses. Account balances are charged off against the allowance when management determines it is probable the receivable will not be recovered. See Note 7 for further information about regulatory deferrals of bad debt expense related to COVID-19.

## (n) Inventory

The Registrants’ inventory consists principally of materials and supplies, and for CERC, natural gas, and for CenterPoint Energy, coal inventory. Materials and supplies are valued at the lower of average cost or market. Materials and supplies are recorded to inventory when purchased and subsequently charged to expense or capitalized to plant when installed. Certain natural gas in storage at CenterPoint Energy’s and CERC’s utilities are recorded using the LIFO method. CenterPoint Energy’s and CERC’s balances in inventory that were valued using LIFO method were as follows:

<table><tr><td rowspan="4">LIFO inventory</td><td colspan="5">Year Ended December 31,</td></tr><tr><td>2021 (1)</td><td>2020</td><td>2021 (1)</td><td>2020 (1)</td><td></td></tr><tr><td colspan="2">CenterPoint Energy</td><td colspan="2">CERC</td><td></td></tr><tr><td colspan="4">(in millions)</td><td></td></tr><tr><td>$</td><td>101</td><td>$</td><td>92</td><td>$</td><td>55</td></tr></table>

(1) Based on the average cost of gas purchased during December 2021, CenterPoint Energy’s and CERC’s cost of replacing inventories carried at LIFO cost was less than the carrying value at December 31, 2021 by $48 million and $0-, respectively.

## (o) Derivative Instruments

The Registrants are exposed to various market risks. These risks arise from transactions entered into in the normal course of business. The Registrants, from time to time, utilize derivative instruments such as physical forward contracts, swaps and options to mitigate the impact of changes in commodity prices, weather and interest rates on operating results and cash flows. Such derivatives are recognized in the Registrants' Consolidated Balance Sheets at their fair value unless the Registrant elects the normal purchase and sales exemption for qualified physical transactions. A derivative may be designated as a normal purchase or normal sale if the intent is to physically receive or deliver the product for use or sale in the normal course of business. CenterPoint Energy elected to record changes in the fair value of amounts excluded from the assessment of effectiveness immediately in its Statements of Consolidated Income.

## (p) Investments in Equity Securities (CenterPoint Energy)

CenterPoint Energy reports equity securities at estimated fair value in the Consolidated Balance Sheets, and any gains and losses, net of any transaction costs, are recorded as Gain (Loss) on Equity Securities in the Statements of Consolidated Income.

## (q) Environmental Costs

The Registrants expense or capitalize environmental expenditures, as appropriate, depending on their future economic benefit. The Registrants expense amounts that relate to an existing condition caused by past operations that do not have future economic benefit. The Registrants record undiscounted liabilities related to these future costs when environmental assessments and/or remediation activities are probable and the costs can be reasonably estimated.

## (r) Cash and Cash Equivalents and Restricted Cash

For purposes of reporting cash flows, the Registrants consider cash equivalents to be short-term, highly-liquid investments with maturities of three months or less from the date of purchase. Cash and cash equivalents held by the Bond Companies (VIEs) solely to support servicing the Securitization Bonds as of December 31, 2021 and 2020 are reflected on CenterPoint Energy’s and Houston Electric’s Consolidated Balance Sheets.

In connection with the issuance of Securitization Bonds, CenterPoint Energy and Houston Electric were required to establish restricted cash accounts to collateralize the bonds that were issued in these financing transactions. These restricted



cash accounts are not available for withdrawal until the maturity of the bonds and are not included in cash and cash equivalents. For more information on restricted cash see Note 19.

## (s) Preferred Stock and Dividends

Preferred stock is evaluated to determine balance sheet classification, and all conversion and redemption features are evaluated for bifurcation treatment. Proceeds received net of issuance costs are recognized on the settlement date. Cash dividends become a liability once declared. Income available to common stockholders is computed by deducting from net income the dividends accumulated and earned during the period on cumulative preferred stock.

## (t) Purchase Accounting

The Registrants evaluate acquisitions to determine when a set of acquired activities and assets represent a business. When control of a business is obtained, the Registrants apply the acquisition method of accounting and record the assets acquired, liabilities assumed and any non-controlling interest obtained based on fair value at the acquisition date. The excess of the fair value of purchase consideration over the fair value of the net assets acquired is recorded as goodwill. The results of operations of the acquired business are included in the Registrants' respective Statements of Consolidated Income beginning on the date of the acquisition.

## (u) New Accounting Pronouncements

Management believes that other recently adopted and recently issued accounting standards that are not yet effective will not have a material impact on the Registrants’ financial position, results of operations or cash flows upon adoption.

(1) SIGECO and AGC own a 300 MW unit at the Warrick Power Plant (Warrick Unit 4) as tenants in common. SIGECO’s share of the cost of this unit as of December 31, 2021, is $196 million with accumulated depreciation totaling $154 million. AGC and SIGECO share equally in the cost of operation and output of the unit. SIGECO’s share



of operating costs is included in Operation and maintenance expense in CenterPoint Energy’s Statements of Consolidated Income.

## (b) Depreciation and Amortization

The following table presents depreciation and amortization expense for 2021, 2020 and 2019:

Year Ended December 31,

## (c) AROs

The Registrants recorded AROs associated with the removal of asbestos and asbestos-containing material in its buildings, including substation building structures. CenterPoint Energy recorded AROs relating to the closure of the ash ponds at A.B. Brown and F.B. Culley. CenterPoint Energy and Houston Electric also recorded AROs relating to treated wood poles for electric distribution, distribution transformers containing PCB (also known as Polychlorinated Biphenyl), and underground fuel storage tanks. CenterPoint Energy and CERC also recorded AROs relating to gas pipelines abandoned in place. The estimates of future liabilities were developed using historical information, and where available, quoted prices from outside contractors.

A reconciliation of the changes in the ARO liability recorded in Other non-current liabilities on each of the Registrants' respective Consolidated Balance Sheets is as follows:

<table><tr><td rowspan="3"></td><td colspan="6">December 31, 2021</td><td colspan="6">December 31, 2020</td></tr><tr><td colspan="2">CenterPoint Energy</td><td colspan="2">Houston Electric</td><td colspan="2">CERC</td><td colspan="2">CenterPoint Energy</td><td colspan="2">Houston Electric</td><td rowspan="2">CERC</td><td></td></tr><tr><td colspan="10">(in millions)</td><td></td></tr><tr><td>Beginning balance</td><td>$</td><td>787</td><td>$</td><td>43</td><td>$</td><td>571</td><td>$</td><td>539</td><td>$</td><td>42</td><td>$</td><td>325</td></tr><tr><td>Accretion expense (1)</td><td></td><td>21</td><td></td><td>1</td><td></td><td>12</td><td></td><td>16</td><td></td><td>1</td><td></td><td>11</td></tr><tr><td>Revisions in estimates (2)</td><td></td><td>(67)</td><td></td><td>(2)</td><td></td><td>(93)</td><td></td><td>232</td><td></td><td>—</td><td></td><td>235</td></tr><tr><td>Ending balance</td><td>$</td><td>741</td><td>$</td><td>42</td><td>$</td><td>490</td><td>$</td><td>787</td><td>$</td><td>43</td><td>$</td><td>571</td></tr></table>

(1) Reflected in Regulatory assets on each of the Registrants' respective Consolidated Balance Sheets.

(2) In 2021, the Registrants reflected a decrease in their respective ARO liability, which is primarily attributable to increases in the long-term interest rates used for discounting in the ARO calculation.

## (4) Held for Sale, Divestitures and Mergers (CenterPoint Energy and CERC)

## Held for Sale

Held for Sale. On April 29, 2021, CenterPoint Energy, through its subsidiary CERC Corp., entered into an Asset Purchase Agreement to sell its Arkansas and Oklahoma Natural Gas businesses for $2.15 billion in cash, including recovery of approximately $425 million in gas cost, including storm-related incremental natural gas costs incurred in the February 2021 Winter Storm Event, subject to certain adjustments set forth in the Asset Purchase Agreement. The assets include approximately 17,000 miles of main pipeline in Arkansas, Oklahoma and certain portions of Bowie County, Texas serving more than half a million customers. The Arkansas and Oklahoma Natural Gas businesses are reflected in CenterPoint Energy’s Natural Gas reportable segment and CERC’s single reportable segment, as applicable. Filings were made on June 11, 2021 to the APSC and June 24, 2021 to the OCC requesting approval of the transaction. On August 18, 2021, the Hart-Scott-Rodino antitrust waiting period expired. On October 14, 2021, a unanimous settlement agreement was filed with the APSC resolving all matters associated with the sale and the FRP. As part of the settlement agreement, CERC committed to provide $22 million in cash at the closing of the transaction, which will be passed through to Arkansas customers. CERC also committed to return any



insurance proceeds it may receive for claims submitted with respect to Arkansas, if any, for costs incurred as part of the February 2021 Winter Storm Event to reduce the balance of the incurred costs. The settlement agreement also provides for the extinguishment of CERC’s obligation to refund through the FRP approximately $10 million as of December 31, 2021. On November 16, 2021, the OCC issued its order approving the transaction, and the order became non-appealable on December 16, 2021. On December 6, 2021, the APSC issued its order approving the transaction, and the order became non-appealable on January 5, 2022. The transaction closed on January 10, 2022.

In April 2021, certain assets and liabilities representing the Arkansas and Oklahoma Natural Gas businesses met the held for sale criteria. The sale is considered an asset sale for tax purposes, requiring net deferred tax liabilities to be excluded from held for sale balances. The deferred taxes associated with the businesses were recognized as a deferred income tax benefit by CenterPoint Energy and CERC upon closing in 2022.

Although the Arkansas and Oklahoma Natural Gas businesses met the held for sale criteria, their disposals do not represent a strategic shift to CenterPoint Energy and CERC, as both will retain significant operations in, and will continue to invest in, their natural gas businesses. Therefore, the assets and liabilities associated with the transaction are not reflected as discontinued operations on CenterPoint Energy’s and CERC’s Statements of Consolidated Income, as applicable, and the December 31, 2020 Consolidated Balance Sheets were not required to be recast for assets held for sale. Since the depreciation on the Arkansas and Oklahoma Natural Gas assets continued to be reflected in revenues through customer rates until the closing of the transaction and will be reflected in the carryover basis of the rate-regulated assets, CenterPoint Energy and CERC continued to record depreciation on those assets through the closing of the transaction.

In September 2021, CNP Midstream entered into the Forward Sale Agreement to sell certain Energy Transfer Common Units upon the completion of the Enable Merger. Additionally, CenterPoint Energy’s announced plan to exit its Midstream Investment reportable segment by the end of 2022 represented a strategic shift that will have a major effect on CenterPoint Energy’s operations or financial results, and as such, its equity investment in Enable are classified and presented as discontinued operations. Equity method investments that qualify for discontinued operations are also presented as assets held for sale. Therefore, the equity in earnings (loss) of unconsolidated affiliates, net of tax, associated with the equity investment in Enable are reflected as discontinued operations on CenterPoint Energy’s Statements of Consolidated Income, and the December 31, 2020 Consolidated Balance Sheet was required to be recast for assets held for sale. For further information about CenterPoint Energy’s equity investment in Enable, see Note 11.

The Registrants record assets and liabilities held for sale at the lower of their carrying value or their estimated fair value less cost to sell. Neither CenterPoint Energy nor CERC recognized any gains or losses on the measurement of assets held for sale during the year ended December 31, 2021. See Note 6 for further information about the allocation of goodwill to the businesses to be disposed.

The assets and liabilities of the Arkansas and Oklahoma Natural Gas businesses and equity method investment in Enable classified as held for sale in CenterPoint Energy’s and CERC’s Consolidated Balance Sheets, as applicable, included the following:

## Discontinued Operations

Enable Merger. On December 2, 2021, Enable, completed the previously announced Enable Merger pursuant to the Enable Merger Agreement entered into on February 16, 2021.

Pursuant to the terms of the Enable Merger Agreement, (i) Elk Merger Sub merged with and into Enable, with Enable surviving as a wholly owned subsidiary of Energy Transfer, (ii) Elk GP Merger Sub merged with and into Enable GP, with Enable GP surviving as a direct wholly owned subsidiary of Energy Transfer and (iii) CenterPoint Energy contributed, assigned, transferred, conveyed and delivered to Energy Transfer, and Energy Transfer acquired, assumed, accepted and received from CenterPoint Energy, all of CenterPoint Energy’s right, title and interest in each Enable Series A Preferred Units issued and outstanding at such time in exchange for 0.0265 newly issued Energy Transfer Series G Preferred Units for each Enable Series A Preferred Unit. Upon the consummation of the transactions contemplated by the Enable Merger Agreement, the agreements relating to Enable between CenterPoint Energy, OGE and Enable and certain of their affiliates terminated, and CenterPoint Energy paid $30 million to OGE.

The Enable Series A Preferred Units are accounted for under Topic 321 - Investments - Equity Securities and are out of scope for held-for-sale and discontinued operations guidance.

At the closing of the Enable Merger on December 2, 2021, Energy Transfer acquired 100% of Enable’s outstanding common units, resulting in the exchange of Enable Common Units owned by CenterPoint Energy at the Enable Merger exchange ratio of 0.8595x Energy Transfer Common Units for each Enable Common Unit. CenterPoint Energy also received $5 million in cash in exchange for its interest in the Enable GP. See Note 19 for supplemental information regarding the non-cash exchange transaction. See Note 12 for further information regarding Energy Transfer security equities.

Divestiture of Infrastructure Services (CenterPoint Energy). On February 3, 2020, CenterPoint Energy, through its subsidiary VUSI, entered into the Securities Purchase Agreement to sell the Infrastructure Services Disposal Group to PowerTeam Services. Subject to the terms and conditions of the Securities Purchase Agreement, PowerTeam Services agreed to purchase all of the outstanding equity interests of VISCO for approximately $850 million, subject to customary adjustments set forth in the Securities Purchase Agreement, including adjustments based on VISCO’s net working capital at closing, indebtedness, cash and cash equivalents and transaction expenses. The transaction closed on April 9, 2020 for $850 million in cash, subject to the working capital adjustment. Additionally, as of December 31, 2020, CenterPoint Energy had a receivable



from PowerTeam Services for working capital and other adjustments set forth in the Security Purchase Agreement. CenterPoint Energy collected a receivable of $4 million from PowerTeam Services in January 2021 for full and final settlement of the working capital adjustment under the Securities Purchase Agreement.

In February 2020, certain assets and liabilities representing the Infrastructure Services Disposal Group met the held for sale criteria and represented all of the businesses within the reporting unit. In accordance with the Securities Purchase Agreement, VISCO was converted from a wholly-owned corporation to a limited liability company that was disregarded for federal income tax purposes immediately prior to the closing of the transaction resulting in the sale of membership units. The sale was considered an asset sale for tax purposes, requiring net deferred tax liabilities of approximately $129 million as of April 9, 2020, the date the transaction closed, to be recognized as a deferred income tax benefit by CenterPoint Energy. Additionally, CenterPoint Energy recognized a current tax expense of $158 million during the year ended December 31, 2020, as a result of the cash taxes payable upon sale.

Upon classifying the Infrastructure Services Disposal Group as held for sale and in connection with the preparation of CenterPoint Energy’s financial statements as of March 31, 2020, CenterPoint Energy recorded a goodwill impairment of approximately $82 million, plus an additional loss of $14 million for cost to sell, during the year ended December 31, 2020. Additionally, CenterPoint Energy recognized a net pre-tax loss of $6 million in connection with the closing of the disposition of the Infrastructure Services Disposal Group during the year ended December 31, 2020, respectively.

In the Securities Purchase Agreement, CenterPoint Energy agreed to a mechanism to reimburse PowerTeam Services subsequent to closing of the sale for certain amounts of specifically identified change orders that may be ultimately rejected by one of VISCO's customers as part of on-going audits. CenterPoint Energy's maximum contractual exposure under the Securities Purchase Agreement, in addition to the amount reflected in the working capital adjustment, for these change orders is $21 million. CenterPoint Energy does not expect the ultimate outcome of this matter to have a material adverse effect on its financial condition, results of operations or cash flows. CenterPoint Energy anticipates this matter will be resolved in 2022."

Divestiture of Energy Services (CenterPoint Energy and CERC). On February 24, 2020, CenterPoint Energy, through its subsidiary CERC Corp., entered into the Equity Purchase Agreement to sell the Energy Services Disposal Group to Symmetry Energy Solutions Acquisition. This transaction did not include CEIP and its assets or MES. Symmetry Energy Solutions Acquisition agreed to purchase all of the outstanding equity interests of the Energy Services Disposal Group for approximately $400 million, subject to customary adjustments set forth in the Equity Purchase Agreement, and inclusive of an estimate of the cash adjustment for the Energy Services Disposal Group's net working capital at closing, indebtedness and transaction expenses. The transaction closed on June 1, 2020 for approximately $286 million in cash, subject to the working capital adjustment. CenterPoint Energy collected a receivable of $79 million from Symmetry Energy Solutions Acquisition in October 2020 for full and final settlement of the working capital adjustment under the Equity Purchase Agreement.

In February 2020, certain assets and liabilities representing the Energy Services Disposal Group met the criteria to be classified as held for sale and represented substantially all of the businesses within the reporting unit. In accordance with the Equity Purchase Agreement, CES was converted from a wholly-owned corporation to a limited liability company that is disregarded for federal income tax purposes immediately prior to the closing of the transaction resulting in the sale of membership units. The sale was considered an asset sale for tax purposes, requiring the net deferred tax liability of approximately $4 million as of June 1, 2020, the date the transaction closed, to be recognized as a deferred tax benefit by CenterPoint Energy and CERC upon closing. Additionally, CenterPoint Energy and CERC recognized current tax expense of $4 million during the year ended December 31, 2020, respectively, as a result of the cash taxes payable upon sale.

Upon classifying the Energy Services Disposal Group as held for sale and in connection with the preparation of CenterPoint Energy’s and CERC’s respective financial statements as of March 31, 2020, CenterPoint Energy and CERC recorded a goodwill impairment of approximately $62 million during the year ended December 31, 2020. Additionally, CenterPoint Energy recognized a loss on assets held for sale of approximately $31 million, plus an additional loss $6 million for cost to sell, recorded only at CenterPoint Energy during the year ended December 31, 2020, respectively. CenterPoint Energy and CERC recognized a gain on sale of $3 million during the year ended December 31, 2020.

As a result of the sale of the Energy Services and Infrastructure Services Disposal Groups, there were no assets or liabilities classified as held for sale as of December 31, 2020.



Because the Infrastructure Services and Energy Services Disposal Groups met the held for sale criteria and their disposals also represent a strategic shift to CenterPoint Energy and CERC, as applicable, the earnings and expenses directly associated with these dispositions, including operating results of the businesses through the date of sale, are reflected as discontinued operations on CenterPoint Energy’s and CERC’s Statements of Consolidated Income, as applicable. As a result, prior periods have also been recast to reflect the earnings or losses from such businesses as income from discontinued operations, net of tax.

A summary of discontinued operations presented in CenterPoint Energy’s Statements of Consolidated Income is as follows:

Other Sale Related Matters of Infrastructure Services and Energy Services (CenterPoint Energy and CERC). CES provided natural gas supply to CenterPoint Energy’s and CERC’s Natural Gas under contracts executed in a competitive bidding process, with the duration of some contracts extending into 2021. In addition, CERC is the natural gas transportation provider for a portion of CES’s customer base and will continue to be the transportation provider for these customers as long as these customers retain a relationship with the divested CES business.



Transactions between CES and CenterPoint Energy’s and CERC’s Natural Gas that were previously eliminated in consolidation have been reflected in continuing operations until the closing of the sale of the Energy Services Disposal Group. Revenues and expenses included in continuing operations were as follows:

<table><tr><td rowspan="3"></td><td colspan="5">Year Ended December 31,</td></tr><tr><td>2020 (1)</td><td>2019</td><td>2020 (1)</td><td>2019</td><td></td></tr><tr><td colspan="2">CenterPoint Energy</td><td colspan="2">CERC</td><td></td></tr><tr><td></td><td></td><td colspan="2">(in millions)</td><td></td><td></td></tr><tr><td>Transportation revenue</td><td>$     34</td><td>$     101</td><td>$     34</td><td>$     101</td><td></td></tr><tr><td>Natural gas expense</td><td>48</td><td>125</td><td>47</td><td>124</td><td></td></tr></table>

(1) Represents charges for the period January 1, 2020 until the closing of the sale of the Energy Services Disposal Group.

In the normal course of business prior to June 1, 2020, the Energy Services Disposal Group through CES traded natural gas under supply contracts and entered into natural gas related transactions under transportation, storage and other contracts. In connection with the Energy Services Disposal Group’s business activities prior to the closing of the sale of the Energy Services Disposal Group on June 1, 2020, CERC Corp. issued guarantees to certain of CES’s counterparties to guarantee the payment of CES’s obligations. For further information, see Note 16.

CenterPoint Energy’s and CERC’s Natural Gas businesses had AMAs associated with their utility distribution service in Arkansas, Louisiana and Oklahoma with the Energy Services Disposal Group that expired in March 2021. See Note 16 for further information.

The Infrastructure Services Disposal Group provided pipeline construction and repair services to CenterPoint Energy’s and CERC’s Natural Gas. In accordance with consolidation guidance in ASC 980—Regulated Operations, costs incurred by Natural Gas utilities for these pipeline construction and repair services are not eliminated in consolidation when capitalized and included in rate base by the Natural Gas utility. Amounts charged for these services that are not capitalized are included primarily in Operation and maintenance expenses.

Fees incurred by CenterPoint Energy’s and CERC’s Natural Gas reportable segment for pipeline construction and repair services are as follows:

<table><tr><td rowspan="3"></td><td colspan="5">Year Ended December 31,</td></tr><tr><td>2020 (1)</td><td>2019 (2)</td><td>2020</td><td>2019</td><td></td></tr><tr><td colspan="2">CenterPoint Energy</td><td colspan="2">CERC</td><td></td></tr><tr><td></td><td></td><td colspan="2">(in millions)</td><td></td><td></td></tr><tr><td>Pipeline construction and repair services capitalized</td><td>$     34</td><td>$     162</td><td>$      —</td><td>$     20</td><td></td><td></td></tr><tr><td>Pipeline construction and repair service charges in operations and maintenance expense</td><td>1</td><td>4</td><td>1</td><td>4</td><td></td><td></td></tr></table>

(2) Represents charges for the period beginning February 1, 2019 through December 31, 2019 due to the Merger.

Divestiture of MES (CenterPoint Energy and CERC). CenterPoint Energy, through its subsidiary CERC Corp., completed the sale of MES on August 31, 2021 to Last Mile Energy. Prior to the transaction, MES provided temporary delivery of LNG and CNG throughout the contiguous 48 states and MES was reflected in CenterPoint Energy’s Natural Gas reportable segment and CERC’s single reportable segment, as applicable.

The MES disposal does not represent a strategic shift to CenterPoint Energy and CERC, as both will retain significant operations in, and will continue to invest in, their natural gas businesses. Therefore, the assets and liabilities associated with MES are not reflected as discontinued operations on CenterPoint Energy’s and CERC’s Statements of Consolidated Income, as applicable, and the December 31, 2020 Consolidated Balance Sheets were not required to be recast for assets held for sale. CenterPoint Energy and CERC recognized a pre-tax gain on the sale of $8 million and $11 million, respectively, during year ended December 31, 2021. See Note 6 for further information about the allocation of goodwill to the MES disposal.



Merger with Vectren. On the Merger Date, pursuant to the Merger Agreement, CenterPoint Energy consummated the previously announced Merger and acquired Vectren for approximately $6 billion in cash. Each share of Vectren common stock issued and outstanding immediately prior to the closing was canceled and converted into the right to receive $72.00 in cash per share, without interest. At the closing, each stock unit payable in Vectren common stock or whose value was determined with reference to the value of Vectren common stock, whether vested or unvested, was canceled with cash consideration paid in accordance with the terms of the Merger Agreement. These amounts did not include a stub period cash dividend of $0.41145 per share, which was declared, with CenterPoint Energy's consent, by Vectren's board of directors on January 16, 2019, and paid to Vectren stockholders as of the Merger Date.

Pursuant to the Merger Agreement and immediately subsequent to the close of the Merger, CenterPoint Energy cash settled $78 million in outstanding share-based awards issued prior to the Merger Date by Vectren to its employees. As a result of the Merger, CenterPoint Energy assumed a liability for these share-based awards of $41 million and recorded an incremental cost of $37 million in Operation and maintenance expenses on its Statements of Consolidated Income during the year ended December 31, 2019 for the accelerated vesting of the awards in accordance with the Merger Agreement.

Subsequent to the close of the Merger, CenterPoint Energy recognized severance totaling $61 million to employees terminated immediately subsequent to the Merger close, inclusive of change of control severance payments to executives of Vectren under existing agreements, and which is included in Operation and maintenance expenses on its Statements of Consolidated Income during the year ended December 31, 2019. Total severance cost for the year ended December 31, 2019 was $102 million.

Amortization expense related to the operation and maintenance agreements and construction backlog was $24 million in 2019, and is included in Non-utility cost of revenues, including natural gas on CenterPoint Energy’s Statements of Consolidated Income. Amortization expense related to customer relationships and trade names was $16 million in 2019 and is included in Depreciation and amortization expense on CenterPoint Energy’s Statements of Consolidated Income.

The results of operations for Vectren included in CenterPoint Energy’s Consolidated Financial Statements from the Merger Date for the year ended December 31, 2019, reflecting results included in both continuing operations and discontinued operations, are as follows:

<table><tr><td>Operating revenues</td><td>$</td><td>2,729</td></tr><tr><td>Net income</td><td>190</td><td></td></tr></table>

CenterPoint Energy incurred integration costs in connection with the Merger of $83 million for the year ended December 31, 2019, which were included in Operation and maintenance expenses in CenterPoint Energy’s Statements of Consolidated Income.

## (5) Revenue Recognition

In accordance with ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which the Registrants expect to be entitled to receive in exchange for these goods or services.

The following tables disaggregate revenues by reportable segment and major source and exclude operating revenues from the Energy Services and Infrastructure Services Disposal Groups, which are reflected as discontinued operations prior to the date of closing of each transaction.

## Revenues from Contracts with Customers

Electric (CenterPoint Energy and Houston Electric). Houston Electric distributes electricity to customers over time and customers consume the electricity when delivered. Indiana Electric generates, distributes and transmits electricity to customers over time, and customers consume the electricity when delivered. Revenue, consisting of both volumetric and fixed tariff rates set by state regulators, such as the PUCT and the IURC, is recognized as electricity is delivered and represents amounts both billed and unbilled. Discretionary services requested by customers are provided at a point in time with control transferring upon the completion of the service. Revenue for discretionary services provided by Houston Electric is recognized upon completion of service based on the tariff rates set by the PUCT. Payments for electricity distribution and discretionary services are aggregated and received on a monthly basis. Houston Electric performs transmission services over time as a stand-ready obligation to provide a reliable network of transmission systems. Revenue is recognized upon time elapsed, and the monthly tariff rate set by the regulator. Payments are received on a monthly basis. Indiana Electric customers are billed monthly and payment terms, set by the regulator, require payment within a month of billing.

Natural Gas (CenterPoint Energy and CERC). CenterPoint Energy and CERC distribute and transport natural gas to customers over time, and customers consume the natural gas when delivered. Revenue, consisting of both volumetric and fixed tariff rates set by the state governing agency for that service area, is recognized as natural gas is delivered and represents amounts both billed and unbilled. Discretionary services requested by the customer are satisfied at a point in time and revenue is recognized upon completion of service and the tariff rates set by the applicable state regulator. Payments of natural gas distribution, transportation and discretionary services are aggregated and received on a monthly basis.

Contract Balances. When the timing of delivery of service is different from the timing of the payments made by customers and when the right to consideration is conditioned on something other than the passage of time, the Registrants recognize either a contract asset (performance precedes billing) or a contract liability (customer payment precedes performance). Those customers that prepay are represented by contract liabilities until the performance obligations are satisfied. The Registrants' contract assets are included in Accrued unbilled revenues in their Consolidated Balance Sheets. As of December 31, 2021, CenterPoint Energy's contract assets primarily relate to Energy Systems Group contracts where revenue is recognized using the input method. The Registrants' contract liabilities are included in Accounts payable and Other current liabilities in their Consolidated Balance Sheets. On an aggregate basis as of December 31, 2021, CenterPoint Energy's contract liabilities primarily relate to Energy Systems Group contracts where revenue is recognized using the input method.

The opening and closing balances of accounts receivable, other accrued unbilled revenue, contract assets and contract liabilities from contracts with customers are as follows:

## CenterPoint Energy

<table><tr><td></td><td>Accounts Receivable</td><td>Other Accrued Unbilled Revenues</td><td>Contract Assets</td><td>Contract Liabilities</td></tr><tr><td></td><td colspan="4">(in millions)</td></tr><tr><td>Opening balance as of December 31, 2020</td><td>$ 604</td><td>$ 505</td><td>$ 27</td><td>$ 18</td></tr><tr><td>Closing balance as of December 31, 2021</td><td>627</td><td>513</td><td>15</td><td>16</td></tr><tr><td>Increase</td><td>$ 23</td><td>$ 8</td><td>$ (12)</td><td>$ (2)</td></tr></table>

The amount of revenue recognized in the year ended December 31, 2021 that was included in the opening contract liability was $17 million. The difference between the opening and closing balances of the contract liabilities primarily results from the timing difference between CenterPoint Energy’s performance and the customer’s payment.



<table><tr><td></td><td>Accounts Receivable</td><td>Other Accrued Unbilled Revenues</td><td>Contract Liabilities</td></tr><tr><td></td><td colspan="3">(in millions)</td></tr><tr><td>Opening balance as of December 31, 2020</td><td>$ 225</td><td>$ 113</td><td>$ 3</td></tr><tr><td>Closing balance as of December 31, 2021</td><td>225</td><td>127</td><td>4</td></tr><tr><td>Increase (decrease)</td><td>$ —</td><td>$ 14</td><td>$ 1</td></tr></table>

The amount of revenue recognized in the year ended December 31, 2021 that was included in the opening contract liability was $3 million. The difference between the opening and closing balances of the contract liabilities primarily results from the timing difference between Houston Electric’s performance and the customer’s payment.

## CERC

CERC does not have any opening or closing contract asset or contract liability balances.

Remaining Performance Obligations (CenterPoint Energy). The table below discloses (1) the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period for contracts and (2) when CenterPoint Energy expects to recognize this revenue. Such contracts include energy performance and sustainable infrastructure services contracts of Energy Systems Group, which are included in Corporate and Other.

Practical Expedients and Exemption. Sales taxes and other similar taxes collected from customers are excluded from the transaction price. For contracts for which revenue from the satisfaction of the performance obligations is recognized in the amount invoiced, the practical expedient was elected and revenue expected to be recognized on these contracts has not been disclosed.

## Allowance for Credit Losses and Bad Debt Expense

CenterPoint Energy and CERC segregate financial assets that fall under the scope of Topic 326, primarily trade receivables due in one year or less, into portfolio segments based on shared risk characteristics, such as geographical location and regulatory environment, for evaluation of expected credit losses. Historical and current information, such as average write-offs, are applied to each portfolio segment to estimate the allowance for losses on uncollectible receivables. Additionally, the allowance for losses on uncollectible receivables is adjusted for reasonable and supportable forecasts of future economic conditions, which can include changing weather, commodity prices, regulations, and macroeconomic factors, among others. Houston Electric had no material changes in its methodology to recognize losses on financial assets that fall under the scope of Topic 326, primarily due to the nature of its customers and regulatory environment. For a discussion of regulatory deferrals related to COVID-19, see Note 7.



The table below summarizes the Registrants’ bad debt expense amounts for 2021, 2020 and 2019, net of regulatory deferrals, including those related to COVID-19:

## (6) Goodwill and Other Intangibles (CenterPoint Energy and CERC)

CenterPoint Energy’s goodwill by reportable segment as of December 31, 2020 and changes in the carrying amount of goodwill as of December 31, 2021 are as follows:

<table><tr><td rowspan="2"></td><td colspan="2">December 31, 2020</td><td colspan="2">Held for Sale</td><td colspan="2">Disposals</td><td colspan="2">December 31, 2021</td></tr><tr><td></td><td></td><td colspan="4">(in millions)</td><td></td><td></td></tr><tr><td>Electric (1)</td><td>$ 936</td><td>$ —</td><td>$ —</td><td>$ —</td><td>$ —</td><td>$ 936</td><td></td><td></td></tr><tr><td>Natural Gas</td><td>3,323</td><td></td><td>398 (2)</td><td></td><td>5 (3)</td><td></td><td>2,920</td><td></td></tr><tr><td>Corporate and Other</td><td>438</td><td></td><td>—</td><td></td><td>—</td><td></td><td>438</td><td></td></tr><tr><td>Total</td><td>$ 4,697</td><td>$ 398</td><td>$ —</td><td>$ 5</td><td>$ —</td><td>$ 4,294</td><td></td><td></td></tr></table>

CERC’s goodwill is as follows:

<table><tr><td rowspan="2"></td><td colspan="2">December 31, 2020</td><td colspan="2">Held for Sale</td><td colspan="2">Disposals</td><td colspan="2">December 31, 2021</td></tr><tr><td></td><td></td><td colspan="4">(in millions)</td><td></td><td></td></tr><tr><td>Goodwill</td><td>$ 757</td><td>$ 144</td><td>(2)</td><td>$ 2</td><td>(3)</td><td>$ 611</td><td></td><td></td></tr></table>

(1) Amount presented is net of the accumulated goodwill impairment charge of $185 million recorded in 2020.

(2) Represents goodwill attributable to the Natural Gas businesses. For further information, see Note 4.

(3) Represents goodwill attributable to the MES disposal. For further information, see Note 4.

When a disposal group reflects a component of a reporting unit and meets the definition of a business, the goodwill within that reporting unit is allocated to the disposal group based on the relative fair value of the components representing a business that will be retained and disposed. As a result, goodwill attributable to the Natural Gas businesses to be disposed is classified as held for sale as of December 31, 2021, and goodwill attributable to MES was reflected in the gain on sale during the year ended December 31, 2021.

CenterPoint Energy and CERC perform goodwill impairment tests at least annually and evaluate goodwill when events or changes in circumstances indicate that its carrying value may not be recoverable. The impairment evaluation for goodwill is performed by comparing the fair value of each reporting unit with the carrying amount of the reporting unit, including goodwill. The estimated fair value of a reporting unit is primarily determined based on an income approach or a weighted combination of income and market approaches. If the carrying amount of the reporting unit is in excess of the estimated fair value of the reporting unit, then the excess amount is the impairment charge that should be recorded, not to exceed the carrying amount of goodwill. See Note 2(g) for further discussion.

CenterPoint Energy and CERC performed the annual goodwill impairment tests in the third quarter of each of 2021 and 2020 and determined that no goodwill impairment charge was required for any reporting unit as a result of those tests.

In connection with their preparation of the financial statements for the three months ended March 31, 2020, CenterPoint Energy and CERC identified triggering events to perform interim goodwill impairment tests for each of their reporting units due to the macroeconomic conditions related in part to the COVID-19 pandemic and the resulting decrease in CenterPoint Energy’s enterprise market capitalization below book value from the decline in CenterPoint Energy’s Common Stock price.

CenterPoint Energy’s interim impairment test in the three months ended March 31, 2020 resulted in a non-cash goodwill impairment charge in the amount of $185 million for a reporting unit, Indiana Electric, within the Electric reportable segment.



The fair value analysis resulted in an implied fair value of goodwill of $936 million for this reporting unit as of March 31, 2020, and as a result, the non-cash impairment charge was recorded in the year ended December 31, 2020.

CenterPoint Energy estimated the fair value of the Indiana Electric reporting unit using primarily an income approach. Under the income approach, the fair value of the reporting unit is determined by using the present value of future expected cash flows, which include management’s projections of the amount and timing of future capital expenditures and the cash inflows from the related regulatory recovery. These estimated future cash flows are then discounted using a rate that approximates the weighted average cost of capital of a market participant. The selection of the discount rate requires significant judgment.

With the exception of Indiana Electric reporting unit discussed above, the fair value of each of CenterPoint Energy’s and CERC’s reporting units exceeded their carrying value, resulting in no goodwill impairment from the March 31, 2020 interim impairment test. See Note 4 for goodwill impairments included within discontinued operations.

## February 2021 Winter Storm Event

In February 2021, certain of the Registrants’ jurisdictions experienced an extreme and unprecedented winter weather event that resulted in prolonged freezing temperatures, which impacted their businesses. In Texas, the February 2021 Winter Storm Event caused an electricity generation shortage that was severely disruptive to Houston Electric’s service territory and the wholesale generation market. While demand for electricity reached extraordinary levels due to the extreme cold, the supply of electricity significantly decreased in part because of the inability of certain power generation facilities to supply electric power to the grid. Houston Electric does not own or operate any electric generation facilities other than leasing facilities that provide temporary emergency electric energy to aid in restoring power to distribution customers during certain widespread power outages as allowed by a new law enacted after the February 2021 Winter Storm Event. Houston Electric transmits and distributes to customers of REPs electric power that the REPs obtain from power generation facilities owned by third parties. ERCOT serves as the independent system operator and regional reliability coordinator for member electric power systems in most of Texas. To comply with ERCOT’s orders, Houston Electric implemented controlled outages across its service territory, resulting in a substantial number of businesses and residents being without power, many for extended periods of time, in compliance with ERCOT’s directives as an emergency procedure to avoid prolonged large-scale state-wide blackouts and long-term damage to the electric system in Texas. In anticipation of this weather event, Houston Electric implemented its emergency operations plan’s processes and procedures necessary to respond to such events, including establishing an incident command center and calling for mutual assistance from other utilities where needed, among other measures. Throughout the February 2021 Winter Storm Event, Houston Electric remained in contact with its regulators and stakeholders, including federal, state and local officials, as well as the PUCT and ERCOT.

The February 2021 Winter Storm Event also impacted wholesale prices of CenterPoint Energy’s and CERC’s natural gas purchases and their ability to serve customers in their Natural Gas service territories, including due to the reduction in available natural gas capacity and impacts to CenterPoint Energy’s and CERC’s natural gas supply portfolio activities, and the effects of weather on their systems and their ability to transport natural gas, among other things. The overall natural gas market, including the markets from which CenterPoint Energy and CERC sourced a significant portion of their natural gas for their operations, experienced significant impacts caused by the February 2021 Winter Storm Event, resulting in extraordinary increases in the price of natural gas purchased by CenterPoint Energy and CERC.

On February 13, 2021, the Railroad Commission authorized each Texas natural gas distribution utility to record in a regulatory asset the extraordinary expenses associated with the February 2021 Winter Storm Event, including, but not limited to, natural gas cost and other costs related to the procurement and transportation of natural gas supply, subject to recovery in future regulatory proceedings. The Texas governor signed legislation in June 2021 that authorizes the Railroad Commission to use securitization financing and the issuance of customer rate relief bonds for recovery of extraordinary natural gas costs incurred by natural gas utilities as a result of the February 2021 Winter Storm Event. On November 12, 2021, the RRC issued a Regulatory Asset Determination Order which authorized CERC to include $1.1 billion in a regulatory asset which should be



included for recovery through customer rate relief bond financing. In addition, CenterPoint Energy’s and CERC’s Natural Gas utilities in jurisdictions outside of Texas deferred under-recovered natural gas cost as regulatory assets under existing recovery mechanisms and are seeking recovery of the increased cost of natural gas. As of December 31, 2021, CenterPoint Energy and CERC have recorded current regulatory assets of $1,410 million and $1,336 million, respectively, of which $154 million related to Arkansas and Oklahoma has been recast to held for sale at both CenterPoint Energy and CERC, and non-current regulatory assets of $583 million and $583 million respectively, of which $244 million related to Arkansas and Oklahoma has been recast to held for sale at both CenterPoint Energy and CERC, associated with the February 2021 Winter Storm Event. See Note 4 for further information.

Amounts for the under recovery of natural gas costs are reflected in regulatory assets included in Prepaid expenses and other current assets and Regulatory assets on CenterPoint Energy’s and CERC’s Condensed Consolidated Balance Sheets. Recovery of natural gas costs within the regulatory assets are probable and are subject to customary regulatory prudence reviews in all jurisdictions that may impact the amounts ultimately recovered. CenterPoint Energy and CERC, as applicable, have begun recovery of natural gas costs in Indiana, Louisiana, Mississippi and Minnesota. CenterPoint Energy and CERC have filed for securitization of natural gas costs in Texas, received commission approval and issuance of financing order in 2022, and expect the Texas Public Financing Authority to issue customer rate relief bonds in 2022. As part of the closing of the sale of CenterPoint Energy’s and CERC’s Natural Gas businesses in Arkansas and Oklahoma, CERC received as part of the purchase price $398 million for unrecovered natural gas costs of the February 2021 Winter Storm Event. In testimonies filed on December 22, 2021 and February 11, 2022, in CERC’s high gas cost prudence review case, the Minnesota Attorney General’s Office, Department of Commerce, and Citizens Utility Board have proposed significant disallowances for all natural gas utilities, resulting in a potential disallowances for CenterPoint Energy and CERC. Recommended disallowances for CERC include up to $45 million proposed by the Department of Commerce, $82 million proposed by the Citizens Utility Board, and $409 million (or in the alternative $57 million) proposed by the Attorney General’s Office. The natural gas costs in Minnesota were incurred in accordance with the plan on file with the MPUC and CenterPoint Energy believes the costs were prudently incurred and are eligible for recovery through an existing mechanism. The MPUC has ordered that the amortization period for extraordinary gas costs resulting from the February 2021 Winter Storm Event be increased from a 27-months to 63-months beginning on January 1, 2022, and that CERC forego recovery of the associated carrying costs. Additionally, due to the uncertainty of timing and method of recovery in some jurisdictions, CenterPoint Energy and CERC may not earn a return on amounts deferred in the regulatory assets associated with the February 2021 Winter Storm Event.

On February 21, 2021, in response to the 2021 February Winter Storm Event, the PUCT issued an order prohibiting REPs from sending a request to TDUs to disconnect such REPs' customers for non-payment, effective February 21, 2021. As a result of this order, Houston Electric did not execute any requests for disconnection from any REPs until the PUCT issued orders for disconnects to resume. In June 2021, the PUCT issued an updated order relating to disconnections and REPs resumed the distribution of disconnection notices thereafter. As of December 31, 2021, as authorized by the PUCT, CenterPoint Energy and Houston Electric recorded a regulatory asset of $8 million for bad debt expenses resulting from REPs' default on their obligation to pay delivery charges to Houston Electric net of collateral. Additionally, as of December 31, 2021, CenterPoint Energy and Houston Electric recorded a regulatory asset of $15 million to defer operations and maintenance costs associated with the February 2021 Winter Storm Event.

See Notes 14 and 16(e) for further information regarding debt financing transactions and litigation related to the February 2021 Winter Storm Event, respectively.

## COVID-19 Regulatory Matters

Governors, public utility commissions and other authorities in the states in which the Registrants operate have issued a number of different orders related to the COVID-19 pandemic, including orders addressing customer non-payment and disconnection. Although the disconnect moratoriums have expired in the Registrants' service territories, CenterPoint Energy continues to support those customers who may need payment assistance, arrangements or extensions.

On March 26, 2020, the PUCT issued two orders related to COVID-19 issues that affect Houston Electric. First, the PUCT issued an order related to accrual of regulatory assets granting authority for utilities to record as a regulatory asset expenses resulting from the effects of COVID-19. In the order, the PUCT noted that it will consider whether a utility’s request for recovery of the regulatory asset is reasonable and necessary in a future proceeding. Second, the PUCT issued an order related to the COVID-19 ERP, as modified, which, in light of the disaster declarations issued by the governor of Texas, authorized a customer assistance program for certain residential customers of electric service in areas of Texas open to customer choice, which includes Houston Electric’s service territory.



The PUCT issued an order on August 27, 2020 to conclude the COVID-19 ERP. The PUCT determined that enrollment in the COVID-19 ERP would end on August 31, 2020 and benefits under the program ended on September 30, 2020. Final claims for reimbursement were required to be submitted to the transmission and distribution utilities by November 30, 2020. The transmission and distribution utilities must file a tariff rider cancellation seven days before the date on which it is estimated that revenues from the COVID-19 ERP are approximately equal to its program expenses. Final program reports were required to be submitted to the PUCT by January 15, 2021. The COVID-19 ERP allows for any over/under collection of program expenses to be recorded as a regulatory asset or liability. In December 2021, Houston Electric filed with the PUCT a proposal to reduce the TCRF revenue requirement by the final amount of COVID-19 ERP regulatory liability balance. On January 25, 2022, the PUCT issued approval of the TCRF update with rates effective March 1, 2022.

The COVID-19 ERP allows program expenses to be recovered in rates. CenterPoint Energy’s and Houston Electric’s COVID-19 ERP regulatory assets were $0-$0 million as of December 31, 2021 and $6 million as of December 31, 2020.

Commissions in all of Indiana Electric’s and CenterPoint Energy’s and CERC’s Natural Gas service territories have either (1) issued orders to record a regulatory asset for incremental bad debt expenses related to COVID-19, including costs associated with the suspension of disconnections and payment plans or (2) provided authority to recover bad debt expense through an existing tracking mechanism. CenterPoint Energy and CERC have recorded estimated incremental uncollectible receivables to the associated regulatory asset of $29 million and $27 million, respectively, as of December 31, 2021 and $22 million and $19 million, respectively, as of December 31, 2020.

In some of the states in which the Registrants operate, public utility commissions have authorized utilities to employ deferred accounting authority for certain COVID-19 related costs which ensure the safety and health of customers, employees, and contractors, that would not have been incurred in the normal course of business. CERC’s Natural Gas service territory in Minnesota will include any offsetting savings in the deferral. Other jurisdictions where the Registrants operate may require them to offset the deferral with savings as well. The Mississippi RRA, filed on April 30, 2021, included the unamortized balance of the regulatory asset as of December 31, 2020 in rate base per Docket No. 2018-AD-141 Order Authorizing Utility Response and Accounting for COVID-19. The Minnesota general rate case filing, filed on November 1, 2021, included a request to recover the COVID-19 regulatory asset balance as of June 30, 2021 over a two-year amortization period.

## (8) Stock-Based Incentive Compensation Plans and Employee Benefit Plans

## (a) Stock-Based Incentive Compensation Plans (CenterPoint Energy)

CenterPoint Energy has LTIPs that provide for the issuance of stock-based incentives, including stock options, performance awards, restricted stock unit awards and restricted and unrestricted stock awards to officers, employees and non-employee directors. Approximately 14 million shares of Common Stock are authorized under these plans for awards. CenterPoint Energy issues new shares of its Common Stock to satisfy stock-based payments related to LTIPs. Equity awards are granted to employees without cost to the participants.

Compensation costs for the performance and stock unit awards granted under LTIPs are measured using fair value and expected achievement levels on the grant date. For performance awards with operational goals, the achievement levels are revised as goals are evaluated. The fair value of awards granted to employees is based on the closing stock price of CenterPoint Energy’s Common Stock on the grant date. The compensation expense is recorded on a straight-line basis over the vesting period. Forfeitures are estimated on the date of grant based on historical averages and estimates are updated periodically throughout the vesting period.

The performance awards granted in 2021, 2020 and 2019 are distributed based upon the achievement of certain objectives over a three-year performance cycle. The stock unit awards granted in 2020 and 2019 are service based, and the stock unit awards granted in 2021 are service based, subject to the achievement of a performance goal. The stock unit awards generally vest at the end of a three-year period, provided, however, that stock unit awards granted to non-employee directors vested immediately upon grant. Upon vesting, shares under the performance and stock unit awards are issued to the participants along with the value of dividend equivalents earned over the performance cycle or vesting period.



The following table summarizes CenterPoint Energy’s expenses related to LTIPs for 2021, 2020 and 2019:

As of December 31, 2021, there was $58 million of total unrecognized compensation cost related to nonvested performance and stock unit awards which is expected to be recognized over a weighted-average period of 1.7 years.



## (b) Pension Benefits (CenterPoint Energy)

CenterPoint Energy maintains a non-contributory qualified defined benefit pension plan covering eligible employees, with benefits determined using a cash balance formula. In addition to the non-contributory qualified defined benefit pension plan, CenterPoint Energy maintains unfunded non-qualified benefit restoration plans which allow participants to receive the benefits to which they would have been entitled under CenterPoint Energy’s non-contributory qualified pension plan except for federally mandated limits on qualified plan benefits or on the level of compensation on which qualified plan benefits may be calculated.

As a result of the Merger, CenterPoint Energy now also maintains three additional qualified defined benefit pension plans, two of which are closed to new participants and one of which is completely frozen, and a non-qualified supplemental retirement plan. The defined benefit pension plans cover eligible full-time regular employees and retirees of Vectren and are primarily non-contributory.

CenterPoint Energy’s net periodic cost includes the following components relating to pension, including the non-qualified benefit plans:

<table><tr><td rowspan="3"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2021</td><td colspan="2">2020</td><td>2019</td></tr><tr><td colspan="4">(in millions)</td></tr><tr><td>Service cost (1)</td><td>$     39</td><td>$     43</td><td>$     40</td><td></td></tr><tr><td>Interest cost (2)</td><td>59</td><td>75</td><td>96</td><td></td></tr><tr><td>Expected return on plan assets (2)</td><td>(103)</td><td>(112)</td><td>(105)</td><td></td></tr><tr><td>Amortization of prior service cost (2)</td><td>—</td><td>—</td><td>9</td><td></td></tr><tr><td>Amortization of net loss (2)</td><td>36</td><td>41</td><td>52</td><td></td></tr><tr><td>Settlement cost (2) (3)</td><td>38</td><td>2</td><td>2</td><td></td></tr><tr><td>Curtailment gain (2) (4)</td><td>—</td><td>—</td><td>(1)</td><td></td></tr><tr><td>Net periodic cost</td><td>$     69</td><td>$     49</td><td>$     93</td><td></td></tr></table>

(1) Amounts presented in the table above are included in Operation and maintenance expense in CenterPoint Energy’s Statements of Consolidated Income, net of regulatory deferrals and amounts capitalized.

(2) Amounts presented in the table above are included in Other, net in CenterPoint Energy’s Statements of Consolidated Income, net of regulatory deferrals.

(3) A one-time, non-cash settlement cost is required when the total lump sum distributions or other settlements of plan benefit obligations during a plan year exceed the service cost and interest cost components of the net periodic cost for that year. In 2021, 2020 and 2019, CenterPoint Energy recognized non-cash settlement cost due to lump sum settlement payments.

(4) A curtailment gain or loss is required when the expected future services of a significant number of employees are reduced or eliminated for the accrual of benefits. In 2019, CenterPoint Energy recognized a pension curtailment gain related to employees who were terminated after the Merger Date.

CenterPoint Energy used the following assumptions to determine net periodic cost relating to pension benefits:

<table><tr><td rowspan="2"></td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2021</td><td>2020</td><td>2019</td></tr><tr><td>Discount rate</td><td>2.45 %</td><td>3.20 %</td><td>4.35 %</td></tr><tr><td>Expected return on plan assets</td><td>5.00</td><td>5.75</td><td>6.00</td></tr><tr><td>Rate of increase in compensation levels</td><td>5.05</td><td>4.95</td><td>4.60</td></tr></table>

In determining net periodic benefit cost, CenterPoint Energy uses fair value, as of the beginning of the year, as its basis for determining expected return on plan assets.



The following table summarizes changes in the benefit obligation, plan assets, the amounts recognized in the Consolidated Balance Sheets as well as the key assumptions of CenterPoint Energy’s pension plans. The measurement dates for plan assets and obligations were December 31, 2021 and 2020.

<table><tr><td rowspan="3"></td><td colspan="3">December 31,</td></tr><tr><td>2021</td><td colspan="2">2020</td></tr><tr><td colspan="3">(in millions, except for actuarial assumptions)</td></tr><tr><td>Change in Benefit Obligation</td><td></td><td></td><td></td></tr><tr><td>Benefit obligation, beginning of year</td><td>$     2,507</td><td>$     2,453</td><td></td></tr><tr><td>Service cost</td><td>38</td><td>43</td><td></td></tr><tr><td>Interest cost</td><td>59</td><td>75</td><td></td></tr><tr><td>Benefits paid</td><td>(285)</td><td>(207)</td><td></td></tr><tr><td>Actuarial (gain) loss (1)</td><td>(22)</td><td>143</td><td></td></tr><tr><td>Plan amendment</td><td>1</td><td>—</td><td></td></tr><tr><td>Benefit obligation, end of year</td><td>2,298</td><td>2,507</td><td></td></tr><tr><td>Change in Plan Assets</td><td></td><td></td><td></td></tr><tr><td>Fair value of plan assets, beginning of year</td><td>2,135</td><td>2,005</td><td></td></tr><tr><td>Employer contributions</td><td>61</td><td>86</td><td></td></tr><tr><td>Benefits paid</td><td>(285)</td><td>(207)</td><td></td></tr><tr><td>Actual investment return</td><td>161</td><td>251</td><td></td></tr><tr><td>Fair value of plan assets, end of year</td><td>2,072</td><td>2,135</td><td></td></tr><tr><td>Funded status, end of year</td><td>$ (226)</td><td>$ (372)</td><td></td></tr><tr><td>Amounts Recognized in Balance Sheets</td><td></td><td></td><td></td></tr><tr><td>Non-current assets</td><td>$     6</td><td>$     </td><td>—</td></tr><tr><td>Current liabilities-other</td><td>(7)</td><td>(8)</td><td></td></tr><tr><td>Other liabilities-benefit obligations</td><td>(225)</td><td>(364)</td><td></td></tr><tr><td>Net liability, end of year</td><td>$ (226)</td><td>$ (372)</td><td></td></tr><tr><td>Actuarial Assumptions</td><td></td><td></td><td></td></tr><tr><td>Discount rate (2)</td><td>2.80%</td><td>2.45%</td><td></td></tr><tr><td>Expected return on plan assets (3)</td><td>5.00</td><td>5.00</td><td></td></tr><tr><td>Rate of increase in compensation levels</td><td>4.95</td><td>5.05</td><td></td></tr><tr><td>Interest crediting rate</td><td>2.25</td><td>2.25</td><td></td></tr></table>

(1) Significant sources of gain for 2021 include the increase in discount rate from 2.45% to 2.80%, and actual return on plan assets exceeding expected return on assets during 2021.

(2) The discount rate assumption was determined by matching the projected cash flows of CenterPoint Energy’s plans against a hypothetical yield curve of high-quality corporate bonds represented by a series of annualized individual discount rates from one-half to 99 years.

(3) The expected rate of return assumption was developed using the targeted asset allocation of CenterPoint Energy’s plans and the expected return for each asset class.

The following table displays pension benefits related to CenterPoint Energy’s pension plans that have accumulated benefit obligations in excess of plan assets:

<table><tr><td rowspan="3"></td><td colspan="5">December 31,</td></tr><tr><td colspan="3">2021</td><td colspan="2">2020</td></tr><tr><td>Pension (Qualified)</td><td>Pension (Non-qualified)</td><td>Pension (Qualified)</td><td>Pension (Non-qualified)</td><td></td></tr><tr><td></td><td colspan="5">(in millions)</td></tr><tr><td>Accumulated benefit obligation</td><td>$ 2,216</td><td>$ 62</td><td>$ 2,427</td><td>$ 68</td><td></td></tr><tr><td>Projected benefit obligation</td><td>2,237</td><td>62</td><td>2,440</td><td>68</td><td></td></tr><tr><td>Fair value of plan assets</td><td>2,072</td><td>—</td><td>2,135</td><td>—</td><td></td></tr></table>

The accumulated benefit obligation for all defined benefit pension plans on CenterPoint Energy’s Consolidated Balance Sheets was $2,278 million and $2,495 million as of December 31, 2021 and 2020, respectively.



## (c) Postretirement Benefits

CenterPoint Energy provides certain healthcare and life insurance benefits for eligible retired employees on both a contributory and non-contributory basis. The Registrants' employees (other than employees of Vectren and its subsidiaries) who were hired before January 1, 2018 and who have met certain age and service requirements at retirement, as defined in the plans, are eligible to participate in these benefit plans, provided, however, that life insurance benefits are available only for eligible retired employees who retired before January 1, 2022. Employees hired on or after January 1, 2018 are not eligible for these benefits, except that such employees represented by IBEW Local Union 66 are eligible to participate in certain of the benefits, subject to the applicable age and service requirements. With respect to retiree medical and prescription drug benefits, and, effective January 1, 2021, dental and vision benefits, employees represented by the IBEW Local Union 66 who retire on or after January 1, 2017, and their dependents, receive any such benefits exclusively through the NECA/IBEW Family Medical Care Plan pursuant to the terms of the applicable collective bargaining agreement. Houston Electric and CERC are required to fund a portion of their obligations in accordance with rate orders. All other obligations are funded on a pay-as-you-go basis.

CenterPoint Energy, through Vectren, also maintains a postretirement benefit plan that provides health care and life insurance benefits, which are a combination of self-insured and fully insured programs, to eligible Vectren retirees on both a contributory and non-contributory basis.

Postretirement benefits are accrued over the active service period of employees. The net postretirement benefit cost includes the following components:

(1) Significant sources of gain for 2021 include updated claims and demographic experience and the increase in discount rate from 2.50% to 2.85%.

(2) The discount rate assumption was determined by matching the projected cash flows of the plans against a hypothetical yield curve of high-quality corporate bonds represented by a series of annualized individual discount rates from one-half to 99 years.

(3) The expected rate of return assumption was developed using the targeted asset allocation of the plans and the expected return for each asset class.



## (d) Accumulated Other Comprehensive Income (Loss) (CenterPoint Energy and CERC)

CenterPoint Energy recognizes the funded status of its pension and other postretirement plans on its Consolidated Balance Sheets. To the extent this obligation exceeds amounts previously recognized in the Statements of Consolidated Income, CenterPoint Energy records a regulatory asset for that portion related to its rate regulated utilities. To the extent that excess liability does not relate to a rate regulated utility, the offset is recorded as a reduction to equity in accumulated other comprehensive income.

Amounts recognized in accumulated other comprehensive loss (gain) consist of the following:

<table><tr><td rowspan="4"></td><td colspan="8">December 31,</td></tr><tr><td colspan="4">2021</td><td colspan="4">2020</td></tr><tr><td colspan="2">Pension Benefits</td><td colspan="2">Postretirement Benefits</td><td colspan="2">Pension Benefits</td><td colspan="2">Postretirement Benefits</td></tr><tr><td>CenterPoint Energy</td><td>CenterPoint Energy</td><td>CERC</td><td>CenterPoint Energy</td><td>CenterPoint Energy</td><td>CERC</td><td></td><td></td></tr><tr><td>Unrecognized actuarial loss (gain)</td><td>$ 99</td><td>$ (23)</td><td>$ (18)</td><td>$ 109</td><td>$ (14)</td><td>$ (12)</td><td></td><td></td></tr><tr><td>Unrecognized prior service cost</td><td>—</td><td>13</td><td>12</td><td>—</td><td>7</td><td>7</td><td></td><td></td></tr><tr><td>Net amount recognized in accumulated other comprehensive loss (gain)</td><td>$ 99</td><td>$ (10)</td><td>$ (6)</td><td>$ 109</td><td>$ (7)</td><td>$ (5)</td><td></td><td></td></tr></table>

The changes in plan assets and benefit obligations recognized in other comprehensive income during 2021 are as follows:

<table><tr><td rowspan="3"></td><td colspan="2">Pension Benefits</td><td colspan="2">Postretirement Benefits</td></tr><tr><td>CenterPoint Energy</td><td>CenterPoint Energy</td><td>CERC</td><td></td></tr><tr><td colspan="4">(in millions)</td></tr><tr><td>Net loss (gain)</td><td>$ 1</td><td>$ (2)</td><td>$ —</td><td></td></tr><tr><td>Amortization of net loss</td><td>(7)</td><td>—</td><td>—</td><td></td></tr><tr><td>Amortization of prior service cost</td><td>—</td><td>(1)</td><td>(1)</td><td></td></tr><tr><td>Settlement</td><td>(4)</td><td>—</td><td>—</td><td></td></tr><tr><td>Total recognized in comprehensive income</td><td>$ (10)</td><td>$ (3)</td><td>$ (1)</td><td></td></tr><tr><td>Total recognized in net periodic costs and Other comprehensive income</td><td>$ 59</td><td>$ —</td><td>$ 3</td><td></td></tr></table>

## (e) Pension Plan Assets (CenterPoint Energy)

In managing the investments associated with the benefit plans, CenterPoint Energy’s objective is to achieve and maintain a fully funded plan. This objective is expected to be achieved through an investment strategy that manages liquidity requirements while maintaining a long-term horizon in making investment decisions and efficient and effective management of plan assets.

As part of the investment strategy discussed above, CenterPoint Energy maintained the following weighted average allocation targets for its pension plans as of December 31, 2021:

<table><tr><td></td><td>Minimum</td><td>Maximum</td></tr><tr><td>U.S. equity</td><td>17 %</td><td>27 %</td></tr><tr><td>International equity</td><td>9 %</td><td>19 %</td></tr><tr><td>Real estate</td><td>2 %</td><td>8 %</td></tr><tr><td>Fixed income</td><td>54 %</td><td>64 %</td></tr><tr><td>Cash</td><td>— %</td><td>2 %</td></tr></table>

Level 2 investments, which do not have a quoted price in active market, are valued using the market data provided by independent pricing services or major market makers, to arrive at a price a dealer would pay for the security.

The pension plans utilized both exchange traded and over-the-counter financial instruments such as futures, interest rate options and swaps that were marked to market daily with the gains/losses settled in the cash accounts. The pension plans did not include any holdings of CenterPoint Energy Common Stock as of December 31, 2021 or 2020.

## (f) Postretirement Plan Assets

In managing the investments associated with the postretirement plans, the Registrants’ primary objective is to preserve and improve the funded status of the plan, while minimizing volatility. This objective is expected to be achieved through an investment strategy that manages liquidity requirements while maintaining a long-term horizon in making investment decisions and efficient and effective management of plan assets.



As part of the investment strategy discussed above, the Registrants maintained the following weighted average allocation targets for the postretirement plans as of December 31, 2021:

<table><tr><td rowspan="2"></td><td colspan="2">CenterPoint Energy</td><td colspan="2">Houston Electric</td><td colspan="2">CERC</td></tr><tr><td>Minimum</td><td>Maximum</td><td>Minimum</td><td>Maximum</td><td>Minimum</td><td>Maximum</td></tr><tr><td>U.S. equities</td><td>13 %</td><td>23 %</td><td>13 %</td><td>23 %</td><td>15 %</td><td>25 %</td></tr><tr><td>International equities</td><td>3 %</td><td>13 %</td><td>3 %</td><td>13 %</td><td>2 %</td><td>12 %</td></tr><tr><td>Fixed income</td><td>69 %</td><td>79 %</td><td>69 %</td><td>79 %</td><td>68 %</td><td>78 %</td></tr><tr><td>Cash</td><td>— %</td><td>2 %</td><td>— %</td><td>2 %</td><td>— %</td><td>2 %</td></tr></table>

## (h) Savings Plan

CenterPoint Energy maintains the CenterPoint Energy Savings Plan, a tax-qualified employee savings plan that includes a cash or deferred arrangement under Section 401(k) of the Code, and an employee stock ownership plan under Section 4975(e)(7) of the Code. Under the plan, participating employees may make pre-tax or Roth contributions and, if eligible, after-tax contributions up to certain federally mandated limits. Participating Registrants provide matching contributions and, as of January 1, 2020, for certain eligible employees, nonelective contributions up to certain limits. CenterPoint Energy, through the Merger, also acquired additional defined contribution retirement savings plans sponsored by Vectren and its subsidiaries that are qualified under sections 401(a) and 401(k) of the Code, one of which merged into the CenterPoint Energy Savings Plan as of January 1, 2020 and one of which merged into the CenterPoint Energy Savings Plan as of January 1, 2022. As of January 1, 2022, the CenterPoint Energy Savings Plan is the only remaining qualified defined contribution retirement savings plan maintained by CenterPoint Energy.

The CenterPoint Energy Savings Plan has significant holdings of Common Stock. As of December 31, 2021, 8,688,841 shares of Common Stock were held by the savings plan, which represented approximately 8% of its investments. Given the concentration of the investments in Common Stock, the savings plan and its participants have market risk related to this investment. The savings plan limits the percentage of future contributions that can be invested in Common Stock to 25% and prohibits transfers of account balances where the transfer would result in more than 25% of a participant’s total account balance invested in Common Stock.

CenterPoint Energy allocates the savings plan benefit expense to Houston Electric and CERC related to their respective employees. The following table summarizes the Registrants’ savings plan benefit expense for 2021, 2020 and 2019:

<table><tr><td rowspan="3"></td><td colspan="12">Year Ended December 31,</td></tr><tr><td colspan="4">2021</td><td colspan="4">2020</td><td colspan="4">2019</td></tr><tr><td>CenterPoint Energy</td><td>Houston Electric</td><td>CERC</td><td>CenterPoint Energy</td><td>Houston Electric</td><td>CERC</td><td>CenterPoint Energy</td><td> Houston Electric</td><td>CERC</td><td>CenterPoint Energy</td><td>Houston Electric</td><td>CERC</td></tr><tr><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Savings plan benefit expenses (1)</td><td>$</td><td>58</td><td>$</td><td>20</td><td>$</td><td>18</td><td>$</td><td>58</td><td>$</td><td>18</td><td>$</td><td>19</td></tr></table>

(1) Amounts presented in the table above are included in Operation and maintenance expense in the Registrants' respective Statements of Consolidated Income and shown prior to any amounts capitalized.

## (i) Other Benefits Plans

The Registrants participate in CenterPoint Energy’s plans that provide postemployment benefits for certain former or inactive employees, their beneficiaries and covered dependents, after employment but before retirement (primarily healthcare and life insurance benefits for participants in the long-term disability plan).

CenterPoint Energy maintains non-qualified deferred compensation plans, including plans acquired in the Merger, that provide benefits payable to eligible directors, officers and select employees or their designated beneficiaries at specified future dates or upon termination, retirement or death. Benefit payments are made from the general assets of the participating Registrants or, in the case of certain plans acquired in the Merger, from a rabbi trust that is a grantor trust and remains subject to the claims of general creditors under applicable state and federal law.



Expenses related to other benefit plans were recorded as follows:

Year Ended December 31,

## (j) Change in Control Agreements and Other Employee Matters

CenterPoint Energy has a change in control plan, which was amended and restated on May 1, 2017. The plan generally provides, to the extent applicable, in the case of a change in control of CenterPoint Energy and covered termination of employment, for severance benefits of up to three times annual base salary plus bonus, and other benefits. Certain CenterPoint Energy officers are participants under the plan.

Certain key employees of a subsidiary of Vectren have employment agreements that provide payments and other benefits upon a covered termination of employment.

As of December 31, 2021, the Registrants’ employees were covered by collective bargaining agreements as follows:

<table><tr><td rowspan="2"></td><td rowspan="2">Agreement Expiration</td><td colspan="3">Percentage of Employees Covered</td></tr><tr><td>CenterPoint Energy</td><td>Houston Electric</td><td>CERC</td></tr><tr><td>IBEW Local 66</td><td>May 2023</td><td>15 %</td><td>54 %</td><td>— %</td></tr><tr><td>OPEIU Local 12</td><td>December 2025</td><td>2 %</td><td>— %</td><td>3 %</td></tr><tr><td>Gas Workers Union Local 340</td><td>April 2025</td><td>5 %</td><td>— %</td><td>12 %</td></tr><tr><td>IBEW Locals 1393 and USW Locals 12213 &amp; 7441</td><td>December 2023</td><td>3 %</td><td>— %</td><td>— %</td></tr><tr><td>IBEW Locals 949</td><td>December 2025</td><td>3 %</td><td>— %</td><td>7 %</td></tr><tr><td>USW Locals 13-227</td><td>June 2022</td><td>5 %</td><td>— %</td><td>14 %</td></tr><tr><td>USW Locals 13-1</td><td>July 2022</td><td>— %</td><td>— %</td><td>1 %</td></tr><tr><td>IBEW Local 702</td><td>June 2022</td><td>3 %</td><td>— %</td><td>— %</td></tr><tr><td>Teamsters Local 135</td><td>October 2024</td><td>— %</td><td>— %</td><td>— %</td></tr><tr><td>UWUA Local 175</td><td>October 2024</td><td>1 %</td><td>— %</td><td>— %</td></tr><tr><td>Total</td><td></td><td>37 %</td><td>54 %</td><td>37 %</td></tr></table>

Negotiations are currently in progress for the collective bargaining agreements scheduled to expire in 2022 and are expected to be completed before the respective expirations.

Board of Directors Actions. On July 22, 2021, CenterPoint Energy announced the decision of the independent directors of the Board to implement a new independent Board leadership and governance structure and appointed a new independent chair of the Board. To implement this new governance structure, the independent directors of the Board eliminated the Executive Chairman position that was formerly held by Milton Carroll.



On the approval and recommendation of the Compensation Committee and approval of the Board (acting solely through its independent directors), CenterPoint Energy entered into a separation agreement between CenterPoint Energy and Mr. Carroll, dated July 21, 2021. Under the terms of the separation agreement, Mr. Carroll exited the positions of Executive Chairman on July 21, 2021 and Board member on September 30, 2021. Under the terms of the separation agreement, Mr. Carroll received a lump sum cash payment of $28 million and his separation was treated as an “enhanced retirement” for purposes of his outstanding 2019, 2020 and 2021 equity award agreements.

On the approval and recommendation of the Compensation Committee and approval of the Board (acting solely through its independent directors), CenterPoint Energy has entered into a retention incentive agreement with David J. Lesar, President and Chief Executive Officer of CenterPoint Energy, dated July 20, 2021. For information about the classification of this award, see Note 13.

## (9) Derivative Instruments

The Registrants are exposed to various market risks. These risks arise from transactions entered into in the normal course of business. The Registrants utilize derivative instruments such as physical forward contracts, swaps and options to mitigate the impact of changes in commodity prices, weather and interest rates on operating results and cash flows.

## (a) Non-Trading Activities

Commodity Derivative Instruments (CenterPoint Energy). CenterPoint Energy, through its Indiana utilities, enters into certain derivative instruments to mitigate the effects of commodity price movements. Outstanding derivative instruments designated as economic hedges at the Indiana Utilities hedge long-term variable rate natural gas purchases. The Indiana utilities have authority to refund and recover mark-to-market gains and losses associated with hedging natural gas purchases, and thus the gains and losses on derivatives are deferred in a regulatory liability or asset. All other financial instruments do not qualify or are not designated as cash flow or fair value hedges.

On February 24, 2020, CenterPoint Energy, through its subsidiary CERC Corp., entered into the Equity Purchase Agreement to sell the Energy Services Disposal Group. The transaction closed on June 1, 2020. As a result, the following disclosures do not include the Energy Services Disposal Group. See Note 4 for further information.

Interest Rate Risk Derivative Instruments. From time to time, the Registrants may enter into interest rate derivatives that are designated as economic or cash flow hedges. The objective of these hedges is to offset risk associated with interest rates borne by the Registrants in connection with an anticipated future fixed rate debt offering or other exposure to variable rate debt. The Indiana Utilities have authority to refund and recover mark-to-market gains and losses associated with hedging financing activity, and thus the gains and losses on derivatives are deferred in a regulatory liability or asset. For the impacts of cash flow hedges to Accumulated other comprehensive income, see Note 13.

The table below summarizes the Registrants’ outstanding interest rate hedging activity:

<table><tr><td rowspan="3">Hedging Classification</td><td>December 31, 2021</td><td>December 31, 2020</td></tr><tr><td colspan="2">Notional Principal</td></tr><tr><td colspan="2">(in millions)</td></tr><tr><td>Economic hedge (1)</td><td>$ 84</td><td>$ 84</td></tr></table>

(1) Relates to interest rate derivative instruments at SIGECO.

Weather Hedges (CenterPoint Energy and CERC). As of December 31, 2021, CenterPoint Energy and CERC had weather normalization or other rate mechanisms that largely mitigate the impact of weather on Natural Gas in Arkansas, Indiana, Louisiana, Mississippi, Minnesota, Ohio and Oklahoma, as applicable. CenterPoint Energy’s and CERC’s Natural Gas in Texas and CenterPoint Energy’s electric operations in Texas and Indiana do not have such mechanisms, although fixed customer charges are historically higher in Texas for Natural Gas compared to its other jurisdictions. As a result, fluctuations from normal weather may have a positive or negative effect on CenterPoint Energy’s and CERC’s Natural Gas’ results in Texas and on CenterPoint Energy’s electric operations’ results in its Texas and Indiana service territories.

CenterPoint Energy and CERC, as applicable, may enter into winter season weather hedges from time to time for certain Natural Gas jurisdictions and electric operations' service territory to mitigate the effect of fluctuations from normal weather on results of operations and cash flows. These weather hedges are based on heating degree days at 10-year normal weather.



Houston Electric and Indiana Electric do not enter into weather hedges. CenterPoint Energy and CERC did not enter into any weather hedges during the year ended December 31, 2021.

## (b) Derivative Fair Values and Income Statement Impacts (CenterPoint Energy)

The following tables present information about derivative instruments and hedging activities. The first table provides a balance sheet overview of Derivative Assets and Liabilities as of December 31, 2021 and 2020, while the last table provides a breakdown of the related income statement impacts for the years ending December 31, 2021, 2020 and 2019.

## (c) Credit Risk Contingent Features (CenterPoint Energy)

Certain of CenterPoint Energy’s derivative instruments contain provisions that require CenterPoint Energy’s debt to maintain an investment grade credit rating on its long-term unsecured unsubordinated debt from S&P and Moody’s. If CenterPoint Energy’s debt were to fall below investment grade, it would be in violation of these provisions, and the counterparties to the derivative instruments could request immediate payment.

<table><tr><td rowspan="3"></td><td colspan="3">As of December 31,</td></tr><tr><td>2021</td><td>2020</td><td></td></tr><tr><td colspan="3">(in millions)</td></tr><tr><td>Aggregate fair value of derivatives with credit-risk-related contingent features in a liability position</td><td>$     14</td><td>$     7</td><td>20</td></tr><tr><td>Fair value of collateral already posted</td><td>7</td><td>7</td><td>7</td></tr><tr><td>Additional collateral required to be posted if credit risk contingent features triggered (1)</td><td>7</td><td>3</td><td></td></tr></table>

(1) The maximum collateral required if further escalating collateral is triggered would equal the net liability position.



## (10) Fair Value Measurements

Assets and liabilities that are recorded at fair value in the Registrants’ Consolidated Balance Sheets are categorized based upon the level of judgment associated with the inputs used to measure their value. Hierarchical levels, as defined below and directly related to the amount of subjectivity associated with the inputs to fair valuations of these assets and liabilities, are as follows:

Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. The types of assets carried at Level 1 fair value generally are exchange-traded derivatives and equity securities, as well as natural gas inventory that has been designated as the hedged item in a fair value hedge.

Level 2: Inputs, other than quoted prices included in Level 1, are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices that are observable for the asset or liability. Fair value assets and liabilities that are generally included in this category are derivatives with fair values based on inputs from actively quoted markets. A market approach is utilized to value the Registrants' Level 2 natural gas derivative assets or liabilities. CenterPoint Energy's Level 2 indexed debt securities derivative is valued using an option model and a discounted cash flow model, which uses projected dividends on the ZENS-Related Securities and a discount rate as observable inputs.

Level 3: Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. Unobservable inputs reflect the Registrants' judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. The Registrants develop these inputs based on the best information available, including the Registrants' own data.

The Registrants determine the appropriate level for each financial asset and liability on a quarterly basis and recognize transfers between levels at the end of the reporting period.

On February 24, 2020, CenterPoint Energy, through its subsidiary CERC Corp., entered into the Equity Purchase Agreement to sell the Energy Services Disposal Group. The transaction closed on June 1, 2020. As a result, the following disclosures do not include the Energy Services Disposal Group. See Note 4 for further information.

The following tables present information about the Registrants’ assets and liabilities (including derivatives that are presented net) measured at fair value on a recurring basis as of December 31, 2021 and December 31, 2020, and indicate the fair value hierarchy of the valuation techniques utilized by the Registrants to determine such fair value.

During 2021 and 2020, CenterPoint Energy did not have any assets or liabilities designated as Level 3.

## Items Measured at Fair Value on a Nonrecurring Basis

As a result of classifying the Arkansas and Oklahoma Natural Gas businesses as held for sale, including the allocation of goodwill, CenterPoint Energy and CERC used a market approach consisting of the contractual sales price adjusted for estimated working capital and other contractual purchase price adjustments to determine fair value of the businesses classified as held for sale, which are Level 2 inputs. Neither CenterPoint Energy nor CERC recognized any gains or losses upon classification of held for sale during 2021. See Note 4 for further information.

Based on the severity of the decline in the price of Enable Common Units during the three months ended March 31, 2020 primarily due to the macroeconomic conditions related in part to the COVID-19 pandemic, combined with Enable’s announcement on April 1, 2020 to reduce its quarterly distributions per Enable Common Unit by 50%, and the market outlook indicating excess supply and continued depressed crude oil and natural gas prices impacting the midstream oil and gas industry, CenterPoint Energy determined, in connection with its preparation of the financial statements, that an other than temporary decrease in the value of its investment in Enable had occurred. The impairment analysis compared the estimated fair value of CenterPoint Energy’s investment in Enable to its carrying value. The fair value of the investment was determined using multiple valuation methodologies under both the market and income approaches. Both of these approaches incorporate significant estimates and assumptions, including:

## Market Approach

• quoted price of Enable Common Units;

• recent market transactions of comparable companies; and

• EBITDA to total enterprise multiples for comparable companies.

## Income Approach

• Enable’s forecasted cash distributions;

• projected cash flows of incentive distribution rights;

• forecasted growth rate of Enable’s cash distributions; and

• determination of the cost of equity, including market risk premiums.

## Weighting of the Different Approaches

Significant unobservable inputs used include the growth rate applied to the projected cash distributions beyond 2020 and the discount rate used to determine the present value of the estimated future cash flows. Based on the significant unobservable estimates and assumptions required, CenterPoint Energy concluded that the fair value estimate should be classified as a Level 3



measurement within the fair value hierarchy. As a result of this analysis, CenterPoint Energy recorded an other than temporary impairment on its investment in Enable of $1,541 million during the year ended December 31, 2020, reducing the carrying value of the investment to its estimated fair value of $848 million as of March 31, 2020. See Note 11 for further discussion of the impairment.

During the year ended December 31, 2020, CenterPoint Energy recorded a goodwill impairment charge of $185 million in the Indiana Electric Integrated reporting unit, reducing the carrying value of the reporting unit to its fair value as of March 31, 2020. See Note 6 for further information.

As a result of classifying the Infrastructure Services and Energy Services Disposal Groups as held for sale, CenterPoint Energy and CERC recognized a goodwill impairment and loss on held for sale during the year ended December 31, 2020. CenterPoint Energy and CERC, as applicable, used the contractual sales price adjusted for estimated working capital and other contractual purchase price adjustments to determine fair value, which are Level 2 inputs. Using this market approach, the fair value of the Infrastructure Services Disposal Group as of March 31, 2020 was determined to be approximately $864 million and the fair value of the Energy Services Disposal Group as of March 31, 2020 was determined to be approximately $402 million. The same methodology was applied to estimate the fair value of the Infrastructure Services Disposal Group and Energy Services Disposal Group on the closing date and through the settlement of the net working capital adjustment, resulting in additional gains or losses upon sale during 2020. See Note 4 for further information.

## Estimated Fair Value of Financial Instruments

The fair values of cash and cash equivalents, investments in debt and equity securities classified as “trading” and short-term borrowings are estimated to be approximately equivalent to carrying amounts and have been excluded from the table below. The carrying amounts of non-trading derivative assets and liabilities and CenterPoint Energy’s equity securities, including ZENS related derivative liabilities, are stated at fair value and are excluded from the table below. The fair value of each debt instrument is determined by multiplying the principal amount of each debt instrument by a combination of historical trading prices and comparable issue data. These liabilities, which are not measured at fair value in the Registrants’ Consolidated Balance Sheets, but for which the fair value is disclosed, would be classified as Level 2 in the fair value hierarchy.

## (11) Unconsolidated Affiliates (CenterPoint Energy and CERC)

Through its investment in Enable, CenterPoint Energy had the ability to significantly influence the operating and financial policies of Enable, a publicly traded MLP, and, accordingly, accounted for its investment in Enable’s common units using the equity method of accounting. Enable was considered to be a VIE because the power to direct the activities that most significantly impact Enable’s economic performance did not reside with the holders of equity investment at risk. However, CenterPoint Energy was not considered the primary beneficiary of Enable since it did not have the power to direct the activities of Enable that were considered most significant to the economic performance of Enable.

On February 16, 2021, Enable entered into the Enable Merger Agreement. On December 2, 2021, the Enable Merger closed pursuant to the Enable Merger Agreement. At the closing of the Enable Merger, CenterPoint Energy transferred 100% of the Enable Common Units and Enable Series A Preferred Units it owned in exchange for Energy Transfer Common Units and Energy Transfer Series G Preferred Units, respectively. CenterPoint Energy also received $5 million in cash in exchange for its interests in Enable GP. CenterPoint Energy has no continuing ownership interest in Enable after the close of the Enable Merger. See Note 12 for further information. Pursuant to previously disclosed support agreements, CenterPoint Energy and OGE, who collectively owned approximately 79.2% of Enable’s common units, delivered written consents approving the Enable Merger Agreement and, on a non-binding, advisory basis, the compensation that will or may become payable to Enable’s named executive officers in connection with the transactions contemplated by the Enable Merger Agreement. Upon the consummation



of the transactions contemplated by the Enable Merger Agreement, the agreements relating to Enable between CenterPoint Energy, OGE and Enable and certain of their affiliates terminated, and CenterPoint Energy paid $30 million to OGE.

The proceeds from the Enable Merger Agreement were allocated to each element based on the relative fair value of the interests being sold. Accordingly, CenterPoint Energy realized gains of $680 million and $1 million related to the transfer of its Enable Common Units and Enable Series A Preferred Units, respectively, from the Enable Merger Agreement. The realized gains from CenterPoint Energy’s transferred Enable Common Units and Enable Series A Preferred Units are reflected as discontinued operations and Other Income, respectively, on CenterPoint Energy’s Statements of Consolidated Income.

The carrying value of CenterPoint Energy’s equity method investment in Enable is reflected as held for sale on CenterPoint Energy’s Consolidated Balance Sheet as of December 31, 2020 and equity in earnings (losses) from Enable are reflected as discontinued operations on CenterPoint Energy’s Statements of Consolidated Income. For further information, see Note 4. The Enable Series A Preferred Units are not reflected in the Midstream Investments reportable segment as equity investments without a readily determinable fair value are not included in the scope of discontinued operations.

## 2020 Impairment in Enable

CenterPoint Energy evaluates its equity method investments, when not reflected as held for sale, for impairment when factors indicate that a decrease in the value of its investment has occurred and the carrying amount of its investment may not be recoverable. An impairment loss, based on the excess of the carrying value over the estimated fair value of the investment, is recognized in earnings when an impairment is deemed to be other than temporary. Considerable judgment is used in determining if an impairment loss is other than temporary and the amount of any impairment. CenterPoint Energy reduced the carrying value of its investment in Enable to its estimated fair value of $848 million as of March 31, 2020 and recognized an impairment charge of $1,541 million during the year ended December 31, 2020. For further information, see Note 10.

CenterPoint Energy and its subsidiaries hold shares of certain securities detailed in the table below, which are classified as trading securities. Shares of AT&T Common and Charter Common are expected to be held to facilitate CenterPoint Energy’s ability to meet its obligation under the ZENS.

## (b) ZENS

In September 1999, CenterPoint Energy issued ZENS having an original principal amount of $1.0 billion of which $828 million remained outstanding as of December 31, 2021. Each ZENS is exchangeable at the holder’s option at any time for an amount of cash equal to 95% of the market value of the reference shares attributable to such note. The number and identity of the reference shares attributable to each ZENS are adjusted for certain corporate events.

CenterPoint Energy’s reference shares for each ZENS consisted of the following:

<table><tr><td rowspan="3"></td><td colspan="2">December 31,</td></tr><tr><td>2021</td><td>2020</td></tr><tr><td colspan="2">(in shares)</td></tr><tr><td>AT&amp;T Common</td><td>0.7185</td><td>0.7185</td></tr><tr><td>Charter Common</td><td>0.061382</td><td>0.061382</td></tr></table>

CenterPoint Energy pays interest on the ZENS at an annual rate of 2% plus the amount of any quarterly cash dividends paid in respect of the reference shares attributable to the ZENS. The principal amount of the ZENS is subject to increases or decreases to the extent that the annual yield from interest and cash dividends on the reference shares is less than or more than 2.309%. The adjusted principal amount is defined in the ZENS instrument as “contingent principal.” As of December 31, 2021, the ZENS, having an original principal amount of $828 million and a contingent principal amount of $38 million, were outstanding and were exchangeable, at the option of the holders, for cash equal to 95% of the market value of the reference shares attributable to the ZENS. As of December 31, 2021, the market value of such shares was approximately $820 million, which would provide an exchange amount of $941 for each $1,000 original principal amount of ZENS. At maturity of the ZENS in 2029, CenterPoint Energy will be obligated to pay in cash the higher of the contingent principal amount of the ZENS.



or an amount based on the then-current market value of the reference shares, which will include any additional publicly-traded securities distributed with respect to the current reference shares prior to maturity.

The ZENS obligation is bifurcated into a debt component and a derivative component (the holder’s option to receive the appreciated value of the reference shares at maturity). The bifurcated debt component accretes through interest charges annually up to the contingent principal amount of the ZENS in 2029. Such accretion will be reduced by annual cash interest payments, as described above. The derivative component is recorded at fair value and changes in the fair value of the derivative component are recorded in CenterPoint Energy’s Statements of Consolidated Income. Changes in the fair value of the ZENS-Related Securities held by CenterPoint Energy are expected to substantially offset changes in the fair value of the derivative component of the ZENS.

The following table sets forth summarized financial information regarding CenterPoint Energy’s investment in ZENS-Related Securities and each component of CenterPoint Energy’s ZENS obligation.

On May 17, 2021, AT&T announced that it had entered into a definitive agreement with Discovery, Inc. to combine their media assets into a new publicly traded company to be called Warner Bros.

At any time within 120 days after the conclusion of any review or appeal process instituted by CenterPoint Energy, if any, following the occurrence of a ratings event, CenterPoint Energy may, at its option, redeem the Series A Preferred Stock in whole, but not in part, at a redemption price in cash per share equal to $1,020 (102% of the liquidation value of $1,000) plus an amount equal to all accumulated and unpaid dividends thereon to, but excluding, the redemption date, whether or not declared.

Ranking. The Series A Preferred Stock, with respect to anticipated dividends and distributions upon CenterPoint Energy’s liquidation or dissolution, or winding-up of CenterPoint Energy’s affairs, ranks or will rank:

- senior to Common Stock and to each other class or series of capital stock established after the initial issue date of the Series A Preferred Stock that is expressly made subordinated to the Series A Preferred Stock;

This right will terminate if and when all accumulated dividends have been paid in full and, upon such termination, the term of office of each director so elected will terminate at such time and the number of directors on CenterPoint Energy’s Board of Directors will automatically decrease by two, subject to the revesting of such rights in the event of each subsequent nonpayment.

## Temporary Equity (CenterPoint Energy)

On the approval and recommendation of the Compensation Committee and approval of the Board (acting solely through its independent directors), CenterPoint Energy entered into a retention incentive agreement with David J. Lesar, President and Chief Executive Officer of CenterPoint Energy, dated July 20, 2021. Under the terms of the retention incentive agreement, Mr. Lesar will receive equity-based awards under CenterPoint Energy’s LTIP covering a total of 1 million shares of Common Stock (Total Stock Award) to be granted in multiple annual awards. In July 2021, 400 thousand restricted stock unit awards were awarded to Mr. Lesar that will vest in December 2022. Restricted stock unit awards covering the remaining 600 thousand shares will be awarded to Mr. Lesar in February 2022 and February 2023, in each case covering the remainder of the Total Stock Award not previously awarded or such lesser number of restricted stock units as may be permitted under the annual individual award limitations under the CenterPoint Energy’s LTIP and vesting in December 2023. These awards will also fully vest upon death, disability, termination without cause, or resignation for good reason, as defined in the award agreements, that occurs prior to the vesting date. In the event any shares under the Total Stock Award remain unawarded, in February 2024, a fully vested stock bonus award of the remaining shares will be granted. For accounting purposes, the 1 million shares under the Total Stock Award, consisting of both the awarded and unawarded equity-based awards described above, were considered granted in July 2021. In the event of death, disability, termination without cause or resignation for good reason, as defined in the retention incentive agreement, that occurs prior to the full Total Stock Award being awarded, CenterPoint Energy will pay a lump sum cash payment equal to the value of the unawarded equity-based awards, based on the closing trading price of Common Stock on the date of the event’s occurrence. Because the unawarded equity-based awards are redeemable for cash upon events that are not probable at the grant date, the equity associated with the unawarded equity-based awards will be classified as Temporary Equity on CenterPoint Energy’s Consolidated Balance Sheets.



## Undistributed Retained Earnings

Liens. As of December 31, 2021, Houston Electric’s assets were subject to liens securing approximately $4.8 billion of general mortgage bonds outstanding under the General Mortgage, including approximately $68 million held in trust to secure pollution control bonds that mature in 2028 for which CenterPoint Energy is obligated. The general mortgage bonds that are held in trust to secure pollution control bonds are not reflected in Houston Electric’s consolidated financial statements because of the contingent nature of the obligations. Houston Electric may issue additional general mortgage bonds on the basis of retired bonds, 70% of property additions or cash deposited with the trustee. Houston Electric could issue approximately $4.6 billion of additional general mortgage bonds on the basis of retired bonds and 70% of property additions as of December 31, 2021. No first mortgage bonds are outstanding under the Mortgage, and Houston Electric is contractually obligated to not issue any additional first mortgage bonds under the Mortgage and is undertaking actions to release the lien of the Mortgage.

As of December 31, 2021, SIGECO had approximately $293 million aggregate principal amount of first mortgage bonds outstanding. Generally, of SIGECO’s real and tangible property is subject to the lien of SIGECO’s mortgage indenture. SIGECO may issue additional bonds under its mortgage indenture up to 60% of currently unfunded property additions. As of December 31, 2021, approximately $1.4 billion of additional first mortgage bonds could be issued on this basis. However, SIGECO is also limited in its ability to issue additional bonds under its mortgage indenture due to certain provisions in its parent’s, VUHI, debt agreements.

Other. As of December 31, 2021, certain financial institutions agreed to issue, from time to time, up to $20 million of letters of credit on behalf of certain of Vectren’s subsidiaries in exchange for customary fees. These agreements to issue letters of credit expire on December 31, 2021. As of December 31, 2021, such financial institutions had issued $1 million of letters of credit on behalf of these subsidiaries.

Tax Attribute Carryforwards and Valuation Allowance. CenterPoint Energy has no federal NOL carryforwards and no federal charitable contribution carryforwards as of December 31, 2021. As of December 31, 2021, CenterPoint Energy had $1.3 billion of state NOL carryforwards that expire between 2022 and 2041, and $7 million of state tax credits that do not expire. CenterPoint Energy reported a valuation allowance of $11 million because it is more likely than not that the benefit from certain state NOL carryforwards will not be realized. Due to a change in the NOL carryforward period in Louisiana from 20 years to an indefinite period during 2021, CenterPoint Energy released a $15 million valuation allowance on certain Louisiana NOLs.

CERC has $2.3 billion of federal NOL carryforwards which have an indefinite carryforward period. CERC has $972 million of gross state NOL carryforwards which expire between 2022 and 2041 and $7 million of state tax credits which do not expire. Due to a change in the NOL carryforward period in Louisiana from 20 years to an indefinite period during 2021, CERC released a $15 million valuation allowance on certain Louisiana NOLs.

A reconciliation of CenterPoint Energy’s beginning and ending balance of unrecognized tax benefits, excluding interest and penalties, for 2021 and 2020 are as follows:

<table><tr><td rowspan="3"></td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2021</td><td>2020</td><td></td></tr><tr><td colspan="3">(in millions)</td></tr><tr><td>Balance, beginning of year</td><td>$ 7</td><td>$ 8</td><td></td></tr><tr><td>Increases related to tax positions of prior years</td><td>—</td><td>3</td><td></td></tr><tr><td>Decreases related to tax positions of prior years</td><td>(4)</td><td>(4)</td><td></td></tr><tr><td>Balance, end of year</td><td>$ 3</td><td>$ 7</td><td></td></tr></table>

CenterPoint Energy’s net unrecognized tax benefits, including penalties and interest, were $4 million as of December 31, 2021 and are included in other non-current liabilities in the Consolidated Financial Statements. Included in the balance of uncertain tax positions as of December 31, 2021 are $2 million of tax benefits that, if recognized, would affect the effective tax rate. The above table does not include $1 million of accrued penalties and interest as of December 31, 2021. During 2021, CenterPoint Energy released a $6 million net uncertain tax liability, including interest and penalties, upon acceptance of an accounting method change filed with the IRS in 2019. The Registrants recognize interest accrued related to unrecognized tax benefits and penalties as income tax expense. The Registrants believe that it is reasonably possible that a decrease of up to $3 million in unrecognized tax benefits, including penalties and interest, may occur in the next 12 months as a result of a lapse of statutes on older exposures, a tax settlement, and/or a resolution of open audits.

Tax Audits and Settlements. Tax years through 2018 have been audited and settled with the IRS for CenterPoint Energy. For the 2019-2021 tax years, the Registrants are participants in the IRS’s Compliance Assurance Process. Vectren’s pre-Merger 2014-2019 tax years are now under audit by IRS.



## (16) Commitments and Contingencies

## (a) Purchase Obligations (CenterPoint Energy and CERC)

Commitments include minimum purchase obligations related to CenterPoint Energy’s and CERC’s Natural Gas reportable segment and CenterPoint Energy’s Electric reportable segment. A purchase obligation is defined as an agreement to purchase goods or services that is enforceable and legally binding on the registrant and that specifies all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. Contracts with minimum payment provisions have various quantity requirements and durations and are not classified as non-trading derivative assets and liabilities in CenterPoint Energy’s and CERC’s Consolidated Balance Sheets as of December 31, 2021 and 2020. These contracts meet an exception as “normal purchases contracts” or do not meet the definition of a derivative. Natural gas and coal supply commitments also include transportation contracts that do not meet the definition of a derivative.

On February 9, 2021, Indiana Electric entered into a BTA with a subsidiary of Capital Dynamics. Pursuant to the BTA, Capital Dynamics, with its partner Tenaska, will build a 300 MW solar array in Posey County, Indiana through a special purpose entity, Posey Solar. Upon completion of construction, currently projected to be at the end of 2023, and subject to IURC approval, which was received on October 27, 2021, Indiana Electric will acquire Posey Solar and its solar array assets for a fixed purchase price. Due to rising cost for the project, caused in part by supply chain issues in the energy industry, the rising cost of commodities and community feedback, CenterPoint Energy, along with Capital Dynamics, recently announced plans to downsize the project to approximately 200 MW. Indiana Electric collaboratively agreed to the scope change and is currently working through contract negotiations, contingent on further IURC review and approval.

As of December 31, 2021, minimum purchase obligations were approximately:

<table><tr><td rowspan="3"></td><td colspan="4">Natural Gas and Coal Supply (1)</td><td>Other (2)</td></tr><tr><td>CenterPoint Energy</td><td colspan="2">CERC</td><td colspan="2">CenterPoint Energy</td></tr><tr><td colspan="5">(in millions)</td></tr><tr><td>2022</td><td>$</td><td>560</td><td>$</td><td>322</td><td>$</td></tr><tr><td>2023</td><td></td><td>444</td><td></td><td>253</td><td></td></tr><tr><td>2024</td><td></td><td>378</td><td></td><td>247</td><td></td></tr><tr><td>2025</td><td></td><td>318</td><td></td><td>206</td><td></td></tr><tr><td>2026</td><td></td><td>254</td><td></td><td>176</td><td></td></tr><tr><td>2027 and beyond</td><td></td><td>1,586</td><td></td><td>1,282</td><td></td></tr></table>

(1) On January 10, 2022, CERC Corp. completed the sale of its Arkansas and Oklahoma Natural Gas businesses; therefore minimum purchase obligations for the Arkansas and Oklahoma Natural Gas businesses have been excluded from the table above. For additional information, see Note 4.

(2) CenterPoint Energy’s undiscounted minimum payment obligations related to PPAs with commitments ranging from 15 to 25 years and its purchase commitment under its BTA in Posey County, Indiana at the original contracted amount, prior to any renegotiation, are included above. The remaining undiscounted payment obligations relate primarily to technology hardware and software agreements.

Excluded from the table above are estimates for cash outlays from other PPAs through Indiana Electric that do not have minimum thresholds but do require payment when energy is generated by the provider. Costs arising from certain of these commitments are pass-through costs, generally collected dollar-for-dollar from retail customers through regulator-approved cost recovery mechanisms.

## (b) AMAs (CenterPoint Energy and CERC)

Upon expiration of the AMAs with the Energy Services Disposal Group discussed in Note 4, CenterPoint Energy’s and CERC’s Natural Gas businesses entered into new third-party AMAs beginning in April 2021 associated with their utility distribution service in Arkansas, Indiana, Louisiana, Mississippi, Oklahoma and Texas. Additionally, CenterPoint Energy’s and CERC’s Natural Gas business in Minnesota entered into a third-party AMA beginning in February 2021. The AMAs have varying terms, the longest of which expires in 2027. Pursuant to the provisions of the agreements, CenterPoint Energy’s and CERC’s Natural Gas either sells natural gas to the asset manager and agrees to repurchase an equivalent amount of natural gas throughout the year at the same cost, or simply purchases its full natural gas requirements at each delivery point from the asset



manager. Generally, AMAs are contracts between CenterPoint Energy’s and CERC’s Natural Gas and an asset manager that are intended to transfer the working capital obligation and maximize the utilization of the assets. In these agreements, CenterPoint Energy’s and CERC’s Natural Gas agrees to release transportation and storage capacity to other parties to manage natural gas storage, supply and delivery arrangements for CenterPoint Energy’s and CERC’s Natural Gas and to use the released capacity for other purposes when it is not needed for CenterPoint Energy’s and CERC’s Natural Gas. CenterPoint Energy’s and CERC’s Natural Gas may receive compensation from the asset manager through payments made over the life of the AMAs. CenterPoint Energy’s and CERC’s Natural Gas has an obligation to purchase their winter storage requirements that have been released to the asset manager under these AMAs. For amounts outstanding under these AMAs, see Notes 4 and 14.

## (c) Guarantees and Product Warranties (CenterPoint Energy)

In the normal course of business, Energy Systems Group enters into contracts requiring it to timely install infrastructure, operate facilities, pay vendors and subcontractors and support warranty obligations and, at times, issue payment and performance bonds and other forms of assurance in connection with these contracts.

Specific to Energy Systems Group’s role as a general contractor in the performance contracting industry, as of December 31, 2021, there were 53 open surety bonds supporting future performance with an aggregate face amount of approximately $569 million. Energy Systems Group’s exposure is less than the face amount of the surety bonds and is limited to the level of uncompleted work under the contracts. As of December 31, 2021, approximately 30% of the work was yet to be completed on projects with open surety bonds. Further, various subcontractors issue surety bonds to Energy Systems Group. In addition to these performance obligations, Energy Systems Group also warrants the functionality of certain installed infrastructure generally for one year and the associated energy savings over a specified number of years. As of December 31, 2021, there were 35 warranties totaling $550 million and an additional $1.2 billion in energy savings commitments not guaranteed by Vectren Corp. Since Energy Systems Group’s inception in 1994, CenterPoint Energy believes Energy Systems Group has had a history of generally meeting its performance obligations and energy savings guarantees and its installed products operating effectively. CenterPoint Energy assessed the fair value of its obligation for such guarantees as of December 31, 2021 and no amounts were recorded on CenterPoint Energy’s Consolidated Balance Sheets.

CenterPoint Energy issues parent company level guarantees to certain vendors, customers and other commercial counterparties of Energy Systems Group. These guarantees do not represent incremental consolidated obligations, but rather, represent guarantees of subsidiary obligations to allow those subsidiaries to conduct business without posting other forms of assurance. As of December 31, 2021, CenterPoint Energy, primarily through Vectren, has issued parent company level guarantees supporting Energy Systems Group's obligations. For those obligations where potential exposure can be estimated, management estimates the maximum exposure under these guarantees to be approximately $514 million as of December 31, 2021. This exposure primarily relates to energy savings guarantees on federal energy savings performance contracts. Other parent company level guarantees, certain of which do not contain a cap on potential liability, have been issued in support of federal operations and maintenance projects for which a maximum exposure cannot be estimated based on the nature of the projects. While there can be no assurance that performance under any of these parent company guarantees will not be required in the future, CenterPoint Energy considers the likelihood of a material amount being incurred as remote.

## (d) Guarantees and Product Warranties (CenterPoint Energy and CERC)

On February 24, 2020, CenterPoint Energy, through its subsidiary CERC Corp., entered into the Equity Purchase Agreement to sell the Energy Services Disposal Group. The transaction closed on June 1, 2020. In the normal course of business prior to June 1, 2020, the Energy Services Disposal Group through CES, traded natural gas under supply contracts and entered into natural gas related transactions under transportation, storage and other contracts. In connection with the Energy Services Disposal Group’s business activities prior to the closing of the sale of the Energy Services Disposal Group on June 1, 2020, CERC Corp. issued guarantees to CES’s counterparties to guarantee the payment of CES’s obligations. When CES remained wholly owned by CERC Corp., these guarantees did not represent incremental consolidated obligations, but rather, these guarantees represented guarantees of CES’s obligations to allow it to conduct business without posting other forms of assurance. See Note 4 for further information.

A CERC Corp. guarantee primarily had a one- or two-year term, although CERC Corp. would generally not be released from obligations incurred by CES prior to the termination of such guarantee unless the beneficiary of the guarantee affirmatively released CERC Corp. from its obligations under the guarantee. Throughout CERC Corp.'s ownership of CES and subsequent to the sale of the Energy Services Disposal Group through December 31, 2021, CERC Corp. did not pay any amounts under guarantees of CES's obligations.



Under the terms of the Equity Purchase Agreement, Symmetry Energy Solutions Acquisition must generally use reasonable best efforts to replace existing CERC Corp. guarantees with credit support provided by a party other than CERC Corp. as of and after the closing of the transaction. Additionally, to the extent that CERC Corp. retains any exposure relating to certain guarantees of CES's obligations 90 days after closing of the transaction, Symmetry Energy Solutions Acquisition will pay a 3% annualized fee on such exposure, increasing by 1% on an annualized basis every three months. As of December 31, 2020, CES had provided replacement credit support to counterparties to whom CERC Corp. had issued guarantees prior to June 1, 2020, representing all 23 million of the estimated remaining exposure under the previously issued guarantees. CERC believes that counterparties to whom replacement credit support has been provided would seek payment if needed under such replacement credit support instead of a CERC Corp. guarantee. No additional guarantees were provided by CERC Corp. to CES subsequent to the closing of the transaction on June 1, 2020.

If CERC Corp. is required to pay a counterparty under a guarantee in respect of obligations of CES, Symmetry Energy Solutions Acquisition is required to promptly reimburse CERC Corp. for all amounts paid. If Symmetry Energy Solutions Acquisition fails to reimburse CERC Corp., CERC Corp. has the contractual right to seek payment from Shell Energy North America (US), L.P. in an amount up to $40 million in the aggregate. While there can be no assurance that payment under any of these guarantees will not be required in the future, CenterPoint Energy and CERC consider the likelihood of a material amount being incurred as remote.

CenterPoint Energy and CERC recorded no amounts on their respective Consolidated Balance Sheets as of December 31, 2021 and December 31, 2020 related to the performance of these guarantees.

## (e) Legal, Environmental and Other Matters

## Legal Matters

Minnehaha Academy (CenterPoint Energy and CERC). On August 2, 2017, a natural gas explosion occurred at the Minnehaha Academy in Minneapolis, Minnesota, resulting in the deaths of two school employees, serious injuries to others and significant property damage to the school. CenterPoint Energy, certain of its subsidiaries, including CERC, and the contractor company working in the school were named in wrongful death, property damage and personal injury litigation arising out of the incident and have now reached confidential settlement agreements in all litigation, and all related governmental matters were previously concluded. CenterPoint Energy’s and CERC’s general and excess liability insurance policies provide coverage for third party bodily injury and property damage claims. These matters are now concluded.

Litigation Related to the Merger (CenterPoint Energy). With respect to the Merger, in July 2018, seven separate lawsuits were filed against Vectren and the individual directors of Vectren's Board of Directors in the U.S. District Court for the Southern District of Indiana. These lawsuits alleged violations of Sections 14(a) of the Exchange Act and SEC Rule 14a-9 on the grounds that the Vectren Proxy Statement filed on June 18, 2018 was materially incomplete because it omitted material information concerning the Merger. The District Court consolidated and subsequently dismissed the lawsuits with prejudice, and the plaintiffs appealed. On September 13, 2021, the U.S. Court of Appeals for the Seventh Circuit affirmed the District Court's order of dismissal. The plaintiffs did not seek rehearing in the Court of Appeals nor review by the Supreme Court of the United States. This matter is now concluded.

Litigation Related to the February 2021 Winter Storm Event. With respect to the February 2021 Winter Storm Event, CenterPoint Energy and Houston Electric, along with ERCOT, power generation companies, and others, have received claims and lawsuits filed by plaintiffs alleging personal injury, property damage and other injuries and damages. Additionally, various regulatory and governmental entities have announced that they intend to conduct or are conducting inquiries, investigations and other reviews of the February 2021 Winter Storm Event and the efforts made by various entities to prepare for, and respond to, this event, including the electric generation shortfall issues. Such entities include the United States Congress, FERC, NERC, Texas RE, ERCOT, Texas government entities and officials such as the Texas Governor's office, the Texas Legislature, the Texas Attorney General, the PUCT, the City of Houston and other municipal and county entities in Houston Electric's service territory, among other entities.

Like other Texas TDUs, Houston Electric has become involved in certain of the above-referenced investigations, litigation or other regulatory and legal proceedings regarding their efforts to restore power and their compliance with NERC, ERCOT and PUCT rules and directives. CenterPoint Energy and Houston Electric have responded to inquiries from the Texas Attorney General and the Galveston County District Attorney’s Office, and CenterPoint Energy and CERC have responded to inquiries from the Arkansas, Minnesota and Oklahoma Attorneys General. CenterPoint Energy and Houston Electric are subject to, and may be further subject to, litigation and claims. Such claims include, or in the future could include, wrongful death, personal



injury and property damage claims, lawsuits for impacts on businesses and other organizations and entities and shareholder claims, among other claims or litigation matters. CenterPoint Energy and Houston Electric, along with numerous other entities, have been named as defendants in such litigation, all of which is now pending in state court as part of a multi-district litigation proceeding. CenterPoint Energy and Houston Electric intend to vigorously defend themselves against the claims raised. CenterPoint Energy, Houston Electric and CERC are unable to predict the consequences of any such matters or to estimate a range of potential losses.

## Environmental Matters

MGP Sites. CenterPoint Energy, CERC and their predecessors operated MGPs in the past. In addition, certain of CenterPoint Energy’s subsidiaries acquired through the Merger operated MGPs in the past. The costs CenterPoint Energy or CERC, as applicable, expect to incur to fulfill their respective obligations are estimated by management using assumptions based on actual costs incurred, the timing of expected future payments and inflation factors, among others. While CenterPoint Energy and CERC have recorded all costs which they presently are obligated to incur in connection with activities at these sites, it is possible that future events may require remedial activities which are not presently foreseen, and those costs may not be subject to PRP or insurance recovery.

(i) Minnesota MGPs (CenterPoint Energy and CERC). With respect to certain Minnesota MGP sites, CenterPoint Energy and CERC have completed state-ordered remediation and continue state-ordered monitoring and water treatment. CenterPoint Energy and CERC recorded a liability as reflected in the table below for continued monitoring and any future remediation required by regulators in Minnesota.

(ii) Indiana MGPs (CenterPoint Energy). In the Indiana Gas service territory, the existence, location and certain general characteristics of 26 gas manufacturing and storage sites have been identified for which CenterPoint Energy may have some remedial responsibility. A remedial investigation/feasibility study was completed at one of the sites under an agreed upon order between Indiana Gas and the IDEM, and a Record of Decision was issued by the IDEM in January 2000. The remaining sites have been submitted to the IDEM’s VRP. CenterPoint Energy has also identified its involvement in 5 manufactured gas plant sites in SIGECO’s service territory, all of which are currently enrolled in the IDEM’s VRP. CenterPoint Energy is currently conducting some level of remedial activities, including groundwater monitoring at certain sites.

(iii) Other MGPs (CenterPoint Energy and CERC). In addition to the Minnesota and Indiana sites, the EPA and other regulators have investigated MGP sites that were owned or operated by CenterPoint Energy or CERC or may have been owned by one of their former affiliates.

Total costs that may be incurred in connection with addressing these sites cannot be determined at this time. The estimated accrued costs are limited to CenterPoint Energy’s and CERC’s share of the remediation efforts and are therefore net of exposures of other PRPs. The estimated range of possible remediation costs for the sites for which CenterPoint Energy and CERC believe they may have responsibility was based on remediation continuing for the minimum time frame given in the table below.

<table><tr><td rowspan="3"></td><td colspan="3">December 31, 2021</td></tr><tr><td>CenterPoint Energy</td><td colspan="2">CERC</td></tr><tr><td colspan="3">(in millions, except years)</td></tr><tr><td>Amount accrued for remediation</td><td>$</td><td>16</td><td>$</td></tr><tr><td>Minimum estimated remediation costs</td><td></td><td>11</td><td></td></tr><tr><td>Maximum estimated remediation costs</td><td></td><td>58</td><td></td></tr><tr><td>Minimum years of remediation</td><td></td><td>5</td><td></td></tr><tr><td>Maximum years of remediation</td><td></td><td>50</td><td></td></tr></table>

The cost estimates are based on studies of a site or industry average costs for remediation of sites of similar size. The actual remediation costs will depend on the number of sites to be remediated, the participation of other PRPs, if any, and the remediation methods used.

CenterPoint Energy and CERC do not expect the ultimate outcome of these matters to have a material adverse effect on the financial condition, results of operations or cash flows of either CenterPoint Energy or CERC.



Asbestos. Some facilities owned by the Registrants or their predecessors contain or have contained asbestos insulation and other asbestos-containing materials. The Registrants are from time to time named, along with numerous others, as defendants in lawsuits filed by a number of individuals who claim injury due to exposure to asbestos, and the Registrants anticipate that additional claims may be asserted in the future. Although their ultimate outcome cannot be predicted at this time, the Registrants do not expect these matters, either individually or in the aggregate, to have a material adverse effect on their financial condition, results of operations or cash flows.

CCR Rule (CenterPoint Energy). In April 2015, the EPA finalized its CCR Rule, which regulates ash as non-hazardous material under the RCRA. The final rule allows beneficial reuse of ash, and the majority of the ash generated by Indiana Electric's generating plants will continue to be reused. In July 2018, the EPA released its final CCR Rule Phase I Reconsideration which extended the deadline to October 31, 2020 for ceasing placement of ash in ponds that exceed groundwater protections standards or that fail to meet location restrictions. In August 2019, the EPA proposed additional "Part A" amendments to its CCR Rule with respect to beneficial reuse of ash and other materials. Further "Part B" amendments, which related to alternate liners for CCR surface impoundments and the surface impoundment closure process, were published in March 2020. The Part A amendments were finalized in August 2020 and extended the deadline to cease placement of ash in ponds to April 11, 2021, discussed further below. The EPA published the final Part B amendments in November 2020. The Part A amendments do not restrict Indiana Electric's current beneficial reuse of its fly ash. CenterPoint Energy evaluated the Part B amendments to determine potential impacts and determined that the Part B amendments did not have an impact on its current plans. Shortly after taking office in January 2021, President Biden signed an executive order requiring agencies to review environmental actions taken by the Trump administration, including the CCR Rule Phase I Reconsideration, the Part A amendments, and the Part B amendments; the EPA has completed its review of the Phase I Reconsideration, Part A amendments, and Part B amendments and determined that the most environmentally protective course is to implement the rules.

Indiana Electric has three ash ponds, two at the F.B. Culley facility (Culley East and Culley West) and one at the A.B. Brown facility. Under the existing CCR Rule, Indiana Electric is required to perform integrity assessments, including ground water monitoring, at its F.B. Culley and A.B. Brown generating stations. The ground water studies are necessary to determine the remaining service life of the ponds and whether a pond must be retrofitted with liners or closed in place. Indiana Electric's Warrick generating unit is not included in the scope of the CCR Rule as this unit has historically been part of a larger generating station that predominantly serves an adjacent industrial facility. Preliminary groundwater monitoring indicates potential groundwater impacts very close to Indiana Electric's ash impoundments, and further analysis is ongoing. The CCR Rule required companies to complete location restriction determinations by October 18, 2018. Indiana Electric completed its evaluation and determined that one F.B. Culley pond (Culley East) and the A.B. Brown pond fail the aquifer placement location restriction. As a result of this failure, Indiana Electric was required to cease disposal of new ash in the ponds and commence closure of the ponds by April 11, 2021, unless approved for an extension. CenterPoint Energy has applied for the extensions available under the CCR Rule that would allow Indiana Electric to continue to use the ponds through October 15, 2023. The EPA is still reviewing industry extension requests, including CenterPoint Energy's extension request. Companies can continue to operate ponds pending completion of the EPA's evaluation of the requests for extension. If the EPA denies a full extension request, that denial may result in increased and potentially significant operational costs in connection with the accelerated implementation of an alternative ash disposal system or may adversely impact Indiana Electric's future operations. Failure to comply with a cease waste receipt could also result in an enforcement proceeding, resulting in the imposition of fines and penalties. On April 24, 2019, Indiana Electric received an order from the IURC approving recovery in rates of costs associated with the closure of the Culley West pond, which has already completed closure activities. On August 14, 2019, Indiana Electric filed its petition with the IURC for recovery of costs associated with the closure of the A.B. Brown ash pond, which would include costs associated with the excavation and recycling of ponded ash. This petition was subsequently approved by the IURC on May 13, 2020. On October 28, 2020, the IURC approved Indiana Electric's ECA proceeding, which included the initiation of recovery of the federally mandated project costs.

Indiana Electric continues to refine site specific estimates of closure costs for its ten-acre Culley East pond. In July 2018, Indiana Electric filed a Complaint for Damages and Declaratory Relief against its insurers seeking reimbursement of defense, investigation and pond closure costs incurred to comply with the CCR Rule, and has since reached confidential settlement agreements with its insurers. The proceeds of these settlements will offset costs that have been and will be incurred to close the ponds.

As of December 31, 2021, CenterPoint Energy has recorded an approximate $90 million ARO, which represents the discounted value of future cash flow estimates to close the ponds at A.B. Brown and F.B. Culley. This estimate is subject to change due to the contractual arrangements; continued assessments of the ash, closure methods, and the timing of closure; implications of Indiana Electric’s generation transition plan; changing environmental regulations; and proceeds received from



the settlements in the aforementioned insurance proceeding. In addition to these removal costs, Indiana Electric also anticipates equipment purchases of between $60 million and $80 million to complete the A.B. Brown closure project.

Clean Water Act Permitting of Groundwater Discharges. In April 2021, the U.S. Supreme Court issued an opinion providing that indirect discharges via groundwater or other non-point sources are subject to permitting and liability under the Clean Water Act when they are the functional equivalent of a direct discharge. The Registrants are evaluating the extent to which this decision will affect Clean Water Act permitting requirements and/or liability for their operations.

Other Environmental. From time to time, the Registrants identify the presence of environmental contaminants during operations or on property where predecessors have conducted operations. Other such sites involving contaminants may be identified in the future. The Registrants have and expect to continue to remediate any identified sites consistent with state and federal legal obligations. From time to time, the Registrants have received notices, and may receive notices in the future, from regulatory authorities or others regarding status as a PRP in connection with sites found to require remediation due to the presence of environmental contaminants. In addition, the Registrants have been, or may be, named from time to time as defendants in litigation related to such sites. Although the ultimate outcome of such matters cannot be predicted at this time, the Registrants do not expect these matters, either individually or in the aggregate, to have a material adverse effect on their financial condition, results of operations or cash flows.

## Other Proceedings

The Registrants are involved in other legal, environmental, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies regarding matters arising in the ordinary course of business. From time to time, the Registrants are also defendants in legal proceedings with respect to claims brought by various plaintiffs against broad groups of participants in the energy industry. Some of these proceedings involve substantial amounts. The Registrants regularly analyze current information and, as necessary, provide accruals for probable and reasonably estimable liabilities on the eventual disposition of these matters. The Registrants do not expect the disposition of these matters to have a material adverse effect on the Registrants' financial condition, results of operations or cash flows.

## (17) Earnings Per Share (CenterPoint Energy)

The Series C Preferred Stock issued in May 2020 were considered participating securities since these shares participated in dividends on Common Stock on a pari passu, pro rata, as-converted basis. As a result, beginning June 30, 2020, earnings per share on Common Stock was computed using the two-class method required for participating securities during the periods the Series C Preferred Stock was outstanding. As of May 7, 2021, all of the remaining outstanding Series C Preferred Stock were converted into shares of Common Stock and earnings per share on Common Stock and, as such, the two-class method was no longer applicable beginning June 30, 2021.

The two-class method uses an earnings allocation formula that treats participating securities as having rights to earnings that otherwise would have been available only to common shareholders. Under the two-class method, income (loss) available to common shareholders from continuing operations is derived by subtracting the following from income (loss) from continuing operations:

• preferred share dividend requirement;

- deemed dividends for the amortization of the beneficial conversion feature recognized at issuance of the Series C Preferred Stock; and

- an allocation of undistributed earnings to preferred shareholders of participating securities (Series C Preferred Stock) based on the securities’ right to receive dividends.

Undistributed earnings are calculated by subtracting dividends declared on Common Stock, the preferred share dividend requirement and deemed dividends for the amortization of the beneficial conversion feature from net income. Net losses are not allocated to the Series C Preferred Stock as it does not have a contractual obligation to share in the losses of CenterPoint Energy.

The Series C Preferred Stock included conversion features at a price that were below the fair value of the Common Stock on the commitment date. This beneficial conversion feature, which was approximately $32 million, represents the difference between the fair value per share of the Common Stock as of the commitment date and the conversion price, multiplied by the number of common shares issuable upon conversion. The beneficial conversion feature was recognized as a discount to Series C Preferred Stock and was amortized as a deemed dividend over the period from the issue date to the first allowable conversion date, which was November 6, 2020.



Basic earnings per common share is computed by dividing income available to common shareholders from continuing operations by the basic weighted average number of common shares outstanding during the period. Participating securities are excluded from basic weighted average number of common shares outstanding. Diluted earnings per common share is computed by dividing income available to common shareholders from continuing operations by the weighted average number of common shares outstanding, including all potentially dilutive common shares, if the effect of such common shares is dilutive.

Diluted earnings per share reflects the dilutive effect of potential common shares from share-based awards and convertible preferred shares. The dilutive effect of the restricted stock, Series B Preferred Stock and Series C Preferred Stock is computed using the if-converted method, which assumes conversion of the restricted stock, Series B Preferred Stock and Series C Preferred Stock at the beginning of the period, giving income recognition for the add-back of the preferred share dividends, amortization of beneficial conversion feature, and undistributed earnings allocated to preferred shareholders. The dilutive effect of restricted stock is computed using the treasury stock method, as applicable, which includes the incremental shares that would be hypothetically vested in excess of the number of shares assumed to be hypothetically repurchased with the assumed proceeds.

The following table reconciles numerators and denominators of CenterPoint Energy’s basic and diluted earnings per common share. Basic earnings per common share is determined by dividing Income available to common shareholders - basic by the Weighted average common shares outstanding - basic for the applicable period. Diluted earnings per common share is determined by the inclusion of potentially dilutive common stock equivalent shares that may occur if securities to issue Common Stock were exercised or converted into Common Stock.

## (18) Reportable Segments

The Registrants’ determination of reportable segments considers the strategic operating units under which its CODM manages sales, allocates resources and assesses performance of various products and services to wholesale or retail customers in differing regulatory environments. Each Registrant’s CODM views net income as the measure of profit or loss for the reportable segments. Certain prior year amounts have been reclassified for assets held for sale and discontinued operations as described below. Additionally, in 2021 CenterPoint Energy transferred certain assets previously recorded in Corporate and Other directly into the reportable segments that received the benefits of such assets, and prior year amounts were reclassified.

As of December 31, 2021, reportable segments by Registrant are as follows:

## CenterPoint Energy

- CenterPoint Energy’s Electric reportable segment consisted of electric transmission and distribution services in the Texas gulf coast area and electric transmission and distribution services primarily to southwestern Indiana and includes power generation and wholesale power operations.

- CenterPoint Energy’s Natural Gas reportable segment consisted of (i) intrastate natural gas sales to, and natural gas transportation and distribution for residential, commercial, industrial and institutional customers in Arkansas, Indiana, Louisiana, Minnesota, Mississippi, Ohio, Oklahoma and Texas; (ii) permanent pipeline connections through interconnects with various interstate and intrastate pipeline companies through CEIP.

CenterPoint Energy’s Corporate and Other consists of energy performance contracting and sustainable infrastructure services through Energy Systems Group and other corporate operations which support all of the business operations of CenterPoint Energy.

## Houston Electric

- Houston Electric’s single reportable segment consisted of electric transmission services to transmission service customers in the ERCOT region and distribution services to REPs in the Texas gulf coast area.

## CERC

- CERC’s single reportable segment consisted of (i) intrastate natural gas sales to, and natural gas transportation and distribution for residential, commercial, industrial and institutional customers in Arkansas, Louisiana, Minnesota, Mississippi, Oklahoma and Texas; and (ii) permanent pipeline connections through interconnects with various interstate and intrastate pipeline companies through CEIP.



Expenditures for long-lived assets include property, plant and equipment. Intersegment sales are eliminated in consolidation, except as described in Note 2(b).

Financial data for reportable segments is as follows, including Corporate and Other and Discontinued Operations for reconciliation purposes:

## Assets Held for Sale and Discontinued Operations (CenterPoint Energy and CERC)

CenterPoint Energy’s Midstream Investments reportable segment presented in the Registrants’ combined 2020 Form 10-K consisted of the equity investment in Enable (excluding the Enable Series A Preferred Units). In September 2021, CenterPoint Energy’s equity investment in Enable met the held for sale criteria and is reflected as discontinued operations, and as a result this reportable segment is not reflected in the financial data for reportable segments. See Notes 4 and 11 for further information regarding CenterPoint Energy’s equity investment in Enable as held for sale and discontinued operations and the completed Enable Merger.

On February 3, 2020, CenterPoint Energy, through its subsidiary VUSI, entered into the Securities Purchase Agreement to sell the Infrastructure Services Disposal Group, which consisted of underground pipeline construction and repair services.

## (21) Leases

An arrangement is determined to be a lease at inception based on whether the Registrant has the right to control the use of an identified asset. ROU assets represent the Registrants' right to use the underlying asset for the lease term and lease liabilities represent the Registrants' obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term, including payments at commencement that depend on an index or rate. Most leases in which the Registrants are the lessee do not have a readily determinable implicit rate, so an incremental borrowing rate, based on the information available at the lease commencement date, is utilized to determine the present value of lease payments. When a secured borrowing rate is not readily available, unsecured borrowing rates are adjusted for the effects of collateral to determine the incremental borrowing rate. Each Registrant uses the implicit rate for agreements in which it is a lessor. Lease income and expense for operating leases and ROU amortization for finance leases are recognized on a straight-line basis over the lease term.

The Registrants have lease agreements with lease and non-lease components and have elected the practical expedient to combine lease and non-lease components for certain classes of leases, such as office buildings and mobile generators. For classes of leases in which lease and non-lease components are not combined, consideration is allocated between components based on the stand-alone prices. Sublease income is not significant to the Registrants.

The Registrants’ lease agreements do not contain any material residual value guarantees, material restrictions or material covenants. There are no material lease transactions with related parties. Agreements in which the Registrants are lessors do not include provisions for the lessee to purchase the assets. Because risk is minimal, the Registrants do not take any significant actions to manage risk associated with the residual value of their leased assets.

The Registrants’ operating lease agreements are primarily equipment and real property leases, including land and office facility leases. CenterPoint Energy and Houston Electric also have finance lease agreements for mobile generators. The Registrants’ lease terms may include options to extend or terminate a lease when it is reasonably certain that those options will



be exercised. The Registrants have elected an accounting policy that exempts leases with terms of one year or less from the recognition requirements of ASC 842.

In 2021 Houston Electric entered into two lease agreements for mobile generation: (1) a temporary short-term lease and (2) a long-term lease. The short-term lease agreement allows Houston Electric to take delivery of mobile generation assets on a short-term basis with a term ending in the third quarter of 2022. Per Houston Electric's short term lease accounting policy election, a ROU asset and lease liability are not reflected on Houston Electric's Consolidated Balance Sheets. Expenses associated with the short-term lease, including carrying costs, are deferred to a regulatory asset and totaled $20 million as of December 31, 2021.

The long-term lease agreement includes up to 505 MW of mobile generation of which 125 MW was delivered by December 31, 2021, triggering lease commencement at delivery, and has an initial term ending in 2029. Houston Electric derecognized the finance lease liability when the extinguishment criteria in Topic 405 - Liabilities were achieved. Per the terms of the agreement, lease payments are due and made in full by Houston Electric upon taking possession of the asset, relieving substantially all of the associated finance lease liability as of December 31, 2021. The remaining finance lease liability associated with the commenced long-term mobile generation agreement was not significant as of December 31, 2021 and relates to removal costs that will be incurred at the end of the lease term. The lease agreement provides Houston Electric a right to terminate between October 2022 and March 2023 if a regulatory event or ruling creates a material adverse condition, which is not reasonably certain to occur. If the right to terminate is elected, seventy-five percent (75%) of Houston Electric's prorated prepaid lease costs would be refunded. Houston Electric made payments under the long-term lease agreement for the 125 MW of mobile generation that was delivered during 2021 into an escrow account, not controlled by Houston Electric, and the funds will be released when the lessor provides Houston Electric with the required information to secure a first lien on the generation equipment.

Houston Electric will also incur variable costs throughout the lease term for the operation and maintenance of the generators. Lease costs, including variable and ROU asset amortization costs, are deferred to Regulatory assets as incurred as a recoverable cost under the 2021 Texas legislation. Houston Electric intends to seek recovery in its DCRF of deferred costs, lease payments, and applicable return, which approximate $200 million under the mobile generation agreements in 2021.

The components of lease cost, included in Operation and maintenance expense on the Registrants’ respective Statements of Consolidated Income, are as follows:

<table><tr><td rowspan="3"></td><td colspan="6">Year Ended December 31, 2021</td><td colspan="4">Year Ended December 31, 2020</td></tr><tr><td colspan="2">CenterPoint Energy</td><td colspan="2">Houston Electric</td><td colspan="2">CERC</td><td colspan="2">CenterPoint Energy</td><td colspan="2">Houston Electric</td></tr><tr><td colspan="10">(in millions)</td></tr><tr><td>Operating lease cost</td><td>$</td><td>8</td><td>$</td><td>1</td><td>$</td><td>4</td><td>$</td><td>9</td><td>$</td><td>—</td></tr><tr><td>Short-term lease cost</td><td>119</td><td>119</td><td>118</td><td>—</td><td>14</td><td>12</td><td>—</td><td>12</td><td>—</td><td>—</td></tr><tr><td>Total lease cost (1)</td><td>$</td><td>127</td><td>$</td><td>119</td><td>$</td><td>4</td><td>$</td><td>23</td><td>$</td><td>5</td></tr></table>

(1) CenterPoint Energy and Houston Electric defer finance lease costs for mobile generation to Regulatory assets for recovery rather than to Depreciation and Amortization in the Statements of Consolidated Income.

## Disclosure Controls And Procedures

In accordance with Exchange Act Rules 13a-15 and 15d-15, the Registrants carried out separate evaluations, under the supervision and with the participation of each company’s management, including the principal executive officer and principal financial officer, of the effectiveness of the disclosure controls and procedures as of the end of the period covered by this report. Based on those evaluations, the principal executive officer and principal financial officer, in each case, concluded that the disclosure controls and procedures were effective as of December 31, 2021 to provide assurance that information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and such information is accumulated and communicated to management, including the principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding disclosure.

There has been no change in the Registrants’ internal controls over financial reporting that occurred during the three months ended December 31, 2021 that has materially affected, or is reasonably likely to materially affect, the Registrants’ internal controls over financial reporting.



## Management’s Annual Report on Internal Control over Financial Reporting

The Registrants’ management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

- Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

- Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

- Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Management has designed its internal control over financial reporting to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with accounting principles generally accepted in the United States of America. Management’s assessment included review and testing of both the design effectiveness and operating effectiveness of controls over all relevant assertions related to all significant accounts and disclosures in the financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

# REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of CenterPoint Energy, Inc.
Houston, Texas

## Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of CenterPoint Energy, Inc. and subsidiaries (the "Company") as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2021, of the Company and our report dated February 22, 2022, expressed an unqualified opinion on those financial statements.

## Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

## Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

## Cautionary Statement and Risk Factors

Certain disclosures in this annual report may be considered “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding our carbon emission reduction goals, including our Net Zero emission goals, and our ability to achieve such goals and related timing thereof, the advancement of and use of new technologies for alternative energy sources, our ability to continue to modernize our distribution grid, executive management continuity and succession planning, future board composition, corporate governance commitments, strategic plans and value creation, capital investments, business opportunities, future financial performance and results of operations, renewable energy growth objectives, growth and guidance (including earnings and customer growth, utility and rate base growth expectations) and any other statement that is not historical fact. The “cautionary statement” on page vii and “certain factors affecting future earnings” beginning on page 43 of CenterPoint Energy’s Form 10-K for the year ended December 31, 2021, and the disclosure referenced therein, should be read in conjunction with the forward-looking statements. Our business is subject to risk and uncertainty. Please refer to our risk factors beginning on page 17 of our Form 10-K.

## Net Zero Disclaimer

While we believe that we have a clear path toward achieving our Net Zero emissions (Scope 1 and Scope 2) by 2035 goals, our analysis and path forward required us to make a number of assumptions. These goals and underlying assumptions involve risks and uncertainties and are not guarantees. Should one or more of our underlying assumptions prove incorrect, our actual results and ability to achieve Net Zero emissions by 2035 could differ materially from our expectations. Certain of the assumptions that could impact our ability to meet our Net Zero emissions goals include: emission levels, service territory size and capacity needs remaining in line with company expectations (inclusive of changes related to the sale of our natural gas businesses in Arkansas and Oklahoma); regulatory approval of our generation transition plan; impacts of future environmental regulations or legislation; impacts of future carbon pricing regulation or legislation; price and availability of carbon offsets; price of fuel, such as natural gas; cost of energy generation technologies, such as wind and solar, natural gas and storage solutions; adoption of alternative energy by the public, including adoption of electric vehicles; rate of technology innovation with regards to alternative energy resources; our ability to implement our modernization plans for our pipelines and facilities; retirement dates of our coal facilities by 2035; and enhancement of energy efficiencies. In addition, because Texas is in an unregulated market, our Scope 2 estimates do not take into account Texas electric transmission and distribution assets in the line loss calculation and exclude emissions related to purchased power between 2024E-2026E. Our Scope 3 estimates do not take into account the emissions of transport customers and emissions related to upstream extraction. Please also review the section entitled “Cautionary Statement Risk Factors” above.

## Use of Non-GAAP Financial Measures by CenterPoint Energy in Providing Guidance

In addition to presenting its financial results in accordance with generally accepted accounting principles (“GAAP”), including presentation of income (loss) available to common shareholders and diluted earnings (loss) per share, CenterPoint Energy provides guidance based on non-GAAP income and non-GAAP diluted earnings per share. Generally, a non-GAAP financial measure is a numerical measure of a company’s historical or future financial performance that excludes or includes amounts that are not normally excluded or included in the most directly comparable GAAP financial measure.

2022 non-GAAP EPS excludes (a) earnings or losses from the change in value of CenterPoint Energy’s 2.0% Zero-Premium Exchangeable Subordinated Notes due 2029 (“ZENS”) and related securities, (b) gain and impact, including related expenses, associated with Arkansas and Oklahoma gas LDC sales, and (c) income and expense related to ownership and disposal of Energy Transfer common and Series G preferred units, and a corresponding amount of debt related to the units. 2022 non-GAAP EPS does not consider the items noted above and other potential impacts, such as changes in accounting standards, impairments or other unusual items, which could have a material impact on GAAP reported results for the applicable guidance period. 2022 non-GAAP EPS also considers assumptions for certain significant variables that may impact earnings, such as customer growth and usage, including normal weather, throughput, recovery of capital invested, effective tax rates, financing activities and related interest rates, and regulatory and judicial proceedings. To the extent actual results deviate from these assumptions, the 2022 non-GAAP EPS guidance range may not be met or the projected annual non-GAAP EPS growth rate may change. CenterPoint Energy is unable to present a quantitative reconciliation of forward-looking non-GAAP EPS because changes in the value of Energy Transfer, ZENS and related securities, future impairments and other unusual items are not estimable and are difficult to predict due to various factors outside of management’s control.

Management evaluates the company’s financial performance in part based on non-GAAP income and non-GAAP EPS. Management believes that presenting these non-GAAP financial measures enhances an investor’s understanding of CenterPoint Energy’s overall financial performance by providing them with an additional meaningful and relevant comparison of current and anticipated future results across periods. The adjustments made in these non-GAAP financial measures exclude items that Management believes do not most accurately reflect the company’s fundamental business performance. CenterPoint Energy’s non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, income available to common shareholders and diluted earnings per share, which are the most directly comparable GAAP financial measures. These non-GAAP financial measures also may be different than non-GAAP financial measures used by other companies.
