PART I

ITEM 1.    BUSINESS.

Overview

ITC Holdings provides safe and reliable electric transmission service to connect consumers to more sustainable and cost-effective energy resources. ITC Holdings continues to make investments in a modernized grid to maintain reliability and accommodate future demands as lifestyles and the economy become increasingly dependent on electricity.

Our business consists primarily of the electric transmission operations of our Regulated Operating Subsidiaries. Through our Regulated Operating Subsidiaries, we own, operate, maintain and invest in high-voltage transmission systems in Michigan’s Lower Peninsula and portions of Iowa, Minnesota, Illinois, Missouri, Kansas, Oklahoma and Wisconsin that transmit electricity from generating stations to local distribution facilities connected to our transmission systems.

Our Regulated Operating Subsidiaries’ primary operating responsibilities include maintaining, improving and expanding their transmission systems to meet their customers’ ongoing needs, scheduling outages on system elements to allow for maintenance and construction, maintaining appropriate system voltages and monitoring flows over transmission lines and other facilities to ensure physical limits are not exceeded.

Our Regulated Operating Subsidiaries earn revenues for the use of their electric transmission systems by their customers, which include investor-owned utilities, municipalities, cooperatives, power marketers and alternative energy suppliers. As independent transmission companies, our Regulated Operating Subsidiaries are subject to rate regulation only by the FERC, and our cost-based rates are discussed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Cost-Based Formula Rates with True-Up Mechanism” as well as in Note 6 to the consolidated financial statements.

ITC Holdings is a wholly-owned subsidiary of ITC Investment Holdings. Fortis owns a majority indirect equity interest in ITC Investment Holdings, with GIC holding an indirect, passive, non-voting equity interest of 19.9%.

Development of Business

As we move toward a cleaner, sustainable and electrified economy, the power grid will need to be transformed and modernized. Technology deployment and innovation are occurring at an accelerated rate within our industry, so we are actively identifying and investing in infrastructure required to meet evolving system needs and energy policy objectives. Our long-term growth plan includes ongoing investments in our current regulated transmission systems and the identification of incremental strategic projects primarily located in and around our service territories.

We expect to invest approximately $5.5 billion from 2024 through 2028 at our Regulated Operating Subsidiaries. Included in this amount are capital expenditures to: (1) maintain and replace our current transmission infrastructure to enhance system reliability and accommodate load growth; (2) interconnect new renewable generation resources; (3) upgrade physical and technological grid security to protect critical infrastructure; and (4) expand access to electricity markets to reduce the overall cost of delivered energy to customers.

Refer to “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Capital Investment and Operating Results Trends” for additional details about our long-term capital investments. Refer to the discussion of risks associated with our strategic investment opportunities in “Item 1A. Risk Factors.”

Operations

As transmission-only companies, our Regulated Operating Subsidiaries function as conduits, allowing for power from generators to be transmitted to local distribution systems either entirely through our Regulated Operating Subsidiaries’ own systems or in conjunction with neighboring transmission systems. Third parties then transmit power through these local distribution systems to end-use consumers. The transmission of electricity by our Regulated Operating Subsidiaries is a central function to the provision of electricity to

8

residential, commercial and industrial end-use consumers. The operations performed by our Regulated Operating Subsidiaries fall into the following categories:

•asset planning;

•engineering;

•safety, protection and preparedness;

•cyber security operations center; and

•real time operations.

Asset Planning

The Asset Planning group performs the role of detailing the required transmission infrastructure needed to support system changes and economic opportunities. System changes can arise from different points of origin including load growth, load shifts, or new points of interconnection; generation retirements or additions; operational needs; and system dynamic stability needs. Likewise, the Asset Planning group explores opportunities to better utilize the transmission system through economic planning by providing access, via transmission expansion projects, to lower cost energy. However, the core responsibility of the Asset Planning group is proactively anticipating the future demands placed upon the transmission system and developing corrective action plans for any deficiencies. Corrective action plans are developed to ensure compliance with NERC’s reliability standards. Additionally, the Asset Planning group seeks opportunities to further develop a resilient transmission system.

Transmission infrastructure plans are submitted as discrete projects into the MISO and SPP planning processes. As the regional planning authorities, MISO and SPP administer open and transparent processes through which the submitted projects are vetted. MISO and SPP produce transmission expansion plans, which include projects to be constructed by their members, including our MISO Regulated Operating Subsidiaries and ITC Great Plains.

Engineering

The Engineering group is composed of the Design, Capital Projects and Asset Management teams. The Engineering group works with outside contractors to perform various aspects of our design, construction and maintenance, but retains internal technical experts who have experience with respect to the key elements of the transmission system such as substations, lines, equipment and protective relaying systems.

Design — The Design team is responsible for the design of our transmission systems and setting the standards for equipment used on our systems.

Capital Projects — The Capital Projects team is responsible for project and construction management for capital projects and associated forecasting, which includes the construction of new transmission infrastructure as well as asset renewal projects.

Asset Management — The Asset Management team performs the following activities:

•manages our vegetation management program;

•provides engineering technical support to the field;

•specifies, maintains and troubleshoots substation and transmission line assets as well as the protection and control systems that are used to protect and monitor our transmission infrastructure; and

•develops and tracks preventative maintenance to promote safe and reliable systems adhering to mandatory requirements of the NERC and the FERC.

By performing preventive maintenance on our assets, we can minimize the need for reactive maintenance, resulting in improved reliability and cost savings for our customers. Our Regulated Operating Subsidiaries contract with ULCS to perform the majority of their maintenance. The agreement with ULCS provides us with access to an experienced and scalable workforce with knowledge of our system at an established rate.

Safety, Protection and Preparedness

The Safety, Protection and Preparedness group is responsible for safety, human performance, physical

9

security, and emergency preparedness and response. Given the inherent hazardous nature of the utilities industry, we proactively work to ensure that all personnel are free to perform in a safe and secure environment. Our focus is to not compromise the safety of our employees, contractors or the public in the course of providing the most reliable electric transmission services. We maintain a safety program that includes proactive measures rooted in human performance principles to achieve that focus. Our emergency response plans ensure that we are prepared for a crisis and can maintain continuity of our business and service. We operate a security command center from our headquarters facility in Michigan that monitors our most critical assets on a continuous basis. The security operations center also gathers intelligence and works with our government and industry partners to monitor and prevent threats to our assets.

Cyber Security Operations Center

The Cyber Security Operations Center protects our business and reputation by securing critical infrastructure, data, and computing systems from threat actors. This group protects vital infrastructure by developing, refining, and continually delivering a comprehensive cybersecurity program while helping stakeholders meet business objectives. See “Item 1C. Cybersecurity” for additional information on our cybersecurity governance, risks and mitigation strategies.

Real Time Operations

System Operations — From our control centers in Michigan, transmission system operators continuously monitor the performance of the transmission systems of our Regulated Operating Subsidiaries, using software and communication systems to perform analysis to plan for contingencies and maintain security and reliability on a continuous basis. Transmission system operators are also responsible for the switching and protective tagging function, taking equipment in and out of service to ensure capital construction projects and maintenance programs can be completed safely and reliably.

Balancing Authority Operator — Under the functional control of MISO, ITCTransmission and METC operate their electric transmission systems as a combined BA area, known as MECS. From our control centers in Michigan, our employees perform the BA functions as outlined in MISO’s Balancing Authority Agreement on a continuous basis. These functions include actual interchange data administration and verification as well as MECS BA area emergency procedure implementation and coordination. No other Regulated Operating Subsidiaries are responsible for BA functions for their respective assets.

Operating Contracts

Our Regulated Operating Subsidiaries have various operating contracts, including numerous interconnection agreements with generation and transmission providers that address terms and conditions of interconnection. The following significant agreements exist at our Regulated Operating Subsidiaries:

ITCTransmission

DTE Electric operates an electric distribution system that is interconnected with ITCTransmission’s transmission system. A set of three operating contracts sets forth the terms and conditions related to DTE Electric’s and ITCTransmission’s interconnected systems. These contracts include the following:

Master Operating Agreement. The MOA governs the primary day-to-day operational responsibilities of ITCTransmission and DTE Electric. The MOA identifies control area coordination services that ITCTransmission provides to DTE Electric and certain generation-based support services that DTE Electric is required to provide to ITCTransmission.

Generator Interconnection and Operation Agreement. The GIOA established and maintains the direct electricity interconnection of DTE Electric’s electricity generating assets with ITCTransmission’s transmission system for the purposes of transmitting electric power from and to the electricity generating facilities.

Coordination and Interconnection Agreement. The CIA outlines the rights, obligations and responsibilities of ITCTransmission and DTE Electric regarding, among other things, the operation and interconnection of DTE Electric’s distribution system and ITCTransmission’s transmission system, and the construction of new facilities or modification of existing facilities. Additionally, the CIA allocates costs for operation of supervisory, communications and metering equipment.

10

METC

Consumers Energy operates an electric distribution system that is interconnected with METC’s transmission system. METC is a party to a number of operating contracts with Consumers Energy that govern the operations and maintenance of its transmission system. These contracts include the following:

Amended and Restated Easement Agreement. Under the Easement Agreement, Consumers Energy provides METC with an easement to the land on which a majority of METC’s transmission towers, poles, lines and other transmission facilities used to transmit electricity for Consumers Energy and others are located. METC pays Consumers Energy an annual rent for the easement and also pays for any rentals, property taxes and other fees related to the property covered by the Easement Agreement.

Amended and Restated Operating Agreement. Under the Operating Agreement, METC is responsible for maintaining and operating its transmission system, providing Consumers Energy with information and access to its transmission system and related books and records, administering and performing the duties of control area operator (that is, the entity exercising operational control over the transmission system) and, if requested by Consumers Energy, building connection facilities necessary to permit interaction with new distribution facilities built by Consumers Energy.

Amended and Restated Purchase and Sale Agreement for Ancillary Services. Since METC does not own any generating facilities, it must procure ancillary services from third party suppliers, such as Consumers Energy. Currently, under the Ancillary Services Agreement, METC pays Consumers Energy for providing certain generation-based services necessary to support the reliable operation of the bulk power grid, such as voltage support and generation capability and capacity to balance loads and generation.

Amended and Restated Distribution-Transmission Interconnection Agreement. The DT Interconnection Agreement provides for the interconnection of Consumers Energy’s distribution system with METC’s transmission system and defines the continuing rights, responsibilities and obligations of the parties with respect to the use of certain of their own and the other party’s properties, assets and facilities.

Amended and Restated Generator Interconnection Agreement. The Generator Interconnection Agreement specifies the terms and conditions under which Consumers Energy and METC maintain the interconnection of Consumers Energy’s generation resources and METC’s transmission assets.

ITC Midwest

IP&L operates an electric distribution system that interconnects with ITC Midwest’s transmission system. ITC Midwest is a party to a number of operating contracts with IP&L that govern the operations and maintenance of their respective systems. These contracts include the following:

Distribution-Transmission Interconnection Agreement. The DTIA governs the rights, responsibilities and obligations of ITC Midwest and IP&L, with respect to the use of certain of their own and the other party’s property, assets and facilities and the construction of new facilities or modification of existing facilities.

Large Generator Interconnection Agreement. ITC Midwest, IP&L and MISO entered into the LGIA in order to establish and maintain the direct electricity interconnection of IP&L’s electricity generating assets with ITC Midwest’s transmission system for the purposes of transmitting electric power from and to the electricity generating facilities.

ITC Great Plains

Amended and Restated Maintenance Agreement. Sunflower and ITC Great Plains have entered into the Sunflower Agreement pursuant to which Sunflower has agreed to perform various field operations and maintenance services related to certain ITC Great Plains assets.

Regulatory Environment

Many regulators and public policy makers support the need for further investment in the transmission grid. The growth and changing mix of electricity generation, wholesale power sales and consumption combined with

11

historically inadequate transmission investment have resulted in significant transmission constraints across the United States and increased stress on aging equipment. These problems will continue without increased investment in transmission infrastructure. Transmission system investments can also increase system reliability and reduce the frequency of power outages. Such investments can reduce transmission constraints and improve access to lower cost generation resources, resulting in a lower overall cost of delivered electricity for end-use consumers. The DOE has established the Office of Electricity that focuses on working with reliability experts from the power industry, state governments and their Canadian counterparts to improve grid reliability and increase investment in the country’s electric infrastructure.

The FERC requires TOs to comply with certain reliability standards and may take enforcement actions for violations, including the imposition of substantial fines. NERC is responsible for developing and enforcing these mandatory reliability standards. We continually assess our transmission systems against standards established by NERC, as well as the standards of applicable regional entities under NERC that have been delegated certain authority for the purpose of proposing and enforcing reliability standards.

Finally, utility holding companies are subject to FERC regulations related to access to books and records in addition to the requirement of the FERC to review and approve mergers and consolidations involving utility assets and holding companies in certain circumstances.

Federal Regulation

As electric transmission companies, our Regulated Operating Subsidiaries charge rates that are regulated by the FERC. The FERC is an independent regulatory commission within the DOE that regulates the interstate transmission and certain wholesale sales of natural gas, the transmission of oil and oil products by pipeline and the transmission and wholesale sales of electricity in interstate commerce. The FERC also administers accounting and financial reporting regulations and standards of conduct for the companies it regulates.

Revenue Requirement Calculations and Cost Sharing for Projects with Regional Benefits

The cost-based Formula Rates used by our Regulated Operating Subsidiaries include revenue requirement calculations for various types of projects. Network revenues continue to be the largest component of revenues recovered through our Formula Rates. However, regional cost sharing revenues have experienced long-term growth as a result of projects that have been identified as having regional benefits and are therefore eligible for regional cost recovery. Separate calculations of revenue requirement are performed for projects that have been approved for regional cost sharing.

We have projects that are eligible for regional cost sharing under the MISO tariff, such as certain network upgrade projects. Additionally, certain projects at ITC Great Plains are eligible for recovery through a region-wide charge pursuant to the SPP tariff.

State Regulation

The regulatory agencies in the states where our Regulated Operating Subsidiaries’ assets are located do not have jurisdiction over our rates or terms and conditions of service. However, they typically have jurisdiction over siting of transmission facilities and related matters as described below. Additionally, we are subject to the regulatory oversight of various state environmental quality departments for compliance with any state environmental standards and regulations.

ITCTransmission and METC

Michigan

The Michigan Public Service Commission has jurisdiction over the siting of certain transmission facilities. Additionally, ITCTransmission and METC have the right as independent transmission companies to condemn property in the state of Michigan for the purposes of building or maintaining transmission facilities.

12

ITC Midwest

Iowa

The Iowa Utilities Board has jurisdiction over the construction, operation and maintenance of transmission facilities in Iowa by any entity, which includes the power to issue franchises. Iowa law further provides that any entity granted a franchise by the Iowa Utilities Board is vested with the power of condemnation in Iowa to the extent the Iowa Utilities Board approves and deems necessary for public use. A city has the power, pursuant to Iowa law, to grant a franchise to erect, maintain and operate transmission facilities within the city limits, which franchise may regulate the conditions required and manner of use of the streets and public grounds of the city and may confer the power to appropriate and condemn private property.

ITC Midwest also is subject to the regulatory oversight of certain state agencies (including the Iowa Department of Natural Resources) and certain local authorities with respect to the issuance of environmental, highway, railroad and similar permits.

Minnesota

The Minnesota Public Utilities Commission has jurisdiction over the construction, siting and routing of new transmission lines and upgrades to existing lines through Minnesota’s Certificate of Need and Route Permit Processes. Transmission companies are also required to participate in the state’s Biennial Transmission Planning Process and are subject to the state’s preventative maintenance requirements. Pursuant to Minnesota law, ITC Midwest has the right as an independent transmission company to condemn property in the state of Minnesota for the purpose of building new transmission facilities.

ITC Midwest is also subject to the regulatory oversight of the Minnesota Pollution Control Agency, the Minnesota Department of Natural Resources, the Minnesota Public Utilities Commission in conjunction with the Department of Commerce and certain local authorities for compliance with applicable environmental standards and regulations.

Illinois

The Illinois Commerce Commission exercises jurisdiction over the siting of new transmission lines through its requirements for Certificates of Public Convenience and Necessity and Right-Of-Way acquisition that apply to construction of new and upgraded facilities.

ITC Midwest is also subject to the regulatory oversight of the Illinois Environmental Protection Agency, the Illinois Department of Natural Resources, the Illinois Pollution Control Board and certain local authorities for compliance with all environmental standards and regulations.

Missouri

Because ITC Midwest is a “public utility” and an “electrical corporation” under Missouri law, the Missouri Public Service Commission has jurisdiction to determine whether ITC Midwest may operate in such capacity. The Missouri Public Service Commission also exercises jurisdiction with regard to other non-rate matters affecting its sole Missouri asset such as transmission substation construction, general safety and the transfer of the franchise or property.

ITC Midwest is also subject to the regulatory oversight of the Missouri Department of Natural Resources for compliance with all environmental standards and regulations relating to this transmission line.

Wisconsin

ITC Midwest is a “public utility” and independent TO in Wisconsin. The Public Service Commission of Wisconsin granted ITC Midwest a certificate of authority to transact public utility business in the state. The Public Service Commission of Wisconsin also recognized ITC Holdings as a public utility holding company under Wisconsin statutes.

The Public Service Commission of Wisconsin exercises jurisdiction over the siting of new transmission lines through the issuance of certificates of authority and certificates of public convenience and necessity. Upon receipt of such certificates for a transmission project, ITC Midwest has condemnation authority as a foreign transmission provider under Wisconsin law. ITC Midwest is also subject to the jurisdiction of certain local and

13

state agencies, including the Wisconsin Department of Natural Resources, relating to environmental and road permits.

ITC Great Plains

Kansas

ITC Great Plains is a “public utility” and an “electric utility” in Kansas pursuant to state statutes. The KCC issued an order approving the issuance of a limited certificate of convenience to ITC Great Plains for the purposes of building, owning and operating SPP transmission projects in Kansas. In addition to its certificate of authority, the KCC has jurisdiction over the siting of electric transmission lines.

ITC Great Plains is also subject to the regulatory oversight of the Kansas Department of Health and Environment for compliance with all environmental standards and regulations relating to the construction phase of any transmission line.

Oklahoma

ITC Great Plains has approval from the Oklahoma Corporation Commission to operate in Oklahoma, pursuant to Oklahoma statutes as an electric public utility providing only transmission services. The Oklahoma Corporation Commission does not exercise jurisdiction over the siting of any transmission lines.

ITC Great Plains is subject to the regulatory oversight of Oklahoma Department of Environmental Quality for compliance with environmental standards and regulations relating to construction and decommissioning of certain proposed transmission facilities.

Sources of Revenue

See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Significant Components of Results of Operations — Revenues” for a discussion of our principal sources of revenue.

Seasonality

The cost-based Formula Rates in effect for our Regulated Operating Subsidiaries, as discussed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Cost-Based Formula Rates with True-Up Mechanism,” mitigate the seasonality of net income for our Regulated Operating Subsidiaries. Our Regulated Operating Subsidiaries accrue or defer revenues to the extent that the actual revenue requirement for the reporting period is higher or lower, respectively, than the amounts billed relating to that reporting period. For example, to the extent that amounts billed are less than our revenue requirement for a reporting period, a revenue accrual is recorded for the difference and the difference results in no net income impact.

Operating cash flows are seasonal at our MISO Regulated Operating Subsidiaries, in that cash received for revenues is typically higher in the summer months when peak load is higher.

Principal Customers

Our principal transmission service customers are DTE Electric, Consumers Energy and IP&L, which accounted for approximately 21.7%, 21.3% and 24.5%, respectively, of our consolidated billed revenues for the year ended December 31, 2023. These customers, together and individually, consistently represent a significant percentage of our operating revenue. This portion of total billed revenues of DTE Electric, Consumers Energy and IP&L include the refund of 2021 revenue accruals and deferrals and exclude any amounts for the 2023 revenue accruals and deferrals that were included in our 2023 operating revenues but will not be billed to our customers until 2025. Refer to “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Cost-Based Formula Rates with True-Up Mechanism” for a discussion on the difference between billed revenues and operating revenues. Our remaining revenues were generated from providing service to other entities such as alternative energy suppliers, power marketers and other wholesale customers that provide electricity to end-use consumers and from transaction-based capacity reservations. Nearly all of our revenues are from transmission customers in the United States. Although we may recognize allocated revenues from time to time from Canadian entities reserving transmission over the Ontario or Manitoba interface, these revenues have not been and are not expected to be material to us.

14

Billing

MISO and SPP are responsible for billing and collecting the majority of our transmission service revenues as well as independently administering the transmission tariff in their respective service territory. As the billing agents for our MISO Regulated Operating Subsidiaries and ITC Great Plains, MISO and SPP independently bill DTE Electric, Consumers Energy, IP&L and other customers on a monthly basis and collect fees for the use of our transmission systems.

See “Item 7A. Quantitative and Qualitative Disclosures about Market Risk — Credit Risk” for discussion of our credit policies.

Competition

Each of our MISO Regulated Operating Subsidiaries operates the primary transmission system in its respective service area and has limited competition for certain projects. While we have rights of first refusal to build projects in certain states in which we operate, other entities with transmission development initiatives may compete with us by seeking approval to be named the party authorized to build new capital projects that we are also pursuing. Our subsidiaries may also compete with other entities on development opportunities for transmission investment in locations outside of our existing service areas.

Human Capital Resources

ITC Holdings places significant emphasis on attracting, developing and retaining individuals who exemplify the values that are the cornerstone of our company. As of December 31, 2023, we had 747 employees, with low employee turnover and no significant change in the number of employees from the prior year. None of our employees are covered by collective bargaining agreements. In addition, we work with many outside firms to provide additional resources to support our business. We utilize human capital resources employed by these firms to assist with construction, maintenance, field operations and other corporate functions of our business. We believe that we have good relationships with our suppliers of contracted services.

Safety is of the utmost importance for our employees, and we consider safety to be a key priority for our company. Our safety policies, procedures and training practices have resulted in safety performance metrics that consistently rank us in the top decile among comparable electric utilities.

We believe that our compensation and benefit programs have been appropriately designed to attract and retain talent. Compensation for employees is made up of a combination of base salary, short-term incentive and long-term incentive pay structures. In addition, we offer a comprehensive package of additional benefits for all of our employees and various professional development opportunities through internal and external programs.

We strive to provide an inclusive and diverse environment for all of our employees. We believe that by recognizing and valuing our employees’ similarities, as well as their differences, we make our shared goals possible. In addition to our internal commitments to inclusion and diversity, we have a supplier diversity program. We expect this effort to further diversify our supplier base through the recruitment and growth of businesses owned by minorities, women and veterans.

ITEM 1A.     RISK FACTORS.

Risks Related to Our Business

Certain elements of our Regulated Operating Subsidiaries’ Formula Rates have been and can be challenged, which could result in lowered rates and/or refunds of amounts previously collected and thus may have an adverse effect on our business, financial condition, results of operations and cash flows.

Our Regulated Operating Subsidiaries provide transmission service under rates regulated by the FERC. The FERC has approved the cost-based Formula Rates used by our Regulated Operating Subsidiaries to calculate their respective annual revenue requirements, but it has not expressly approved the amount of actual capital and operating expenditures to be used in the Formula Rates. All aspects of our Regulated Operating Subsidiaries’ rates approved by the FERC, including the Formula Rate templates, the rates of return on the actual equity portion of their respective capital structures, ROE adders for independent transmission ownership and RTO participation, the approved capital structures and other aspects of our rates, are subject to challenge by interested parties at the FERC, or by the FERC on its own initiative in a proceeding under Section 206 of the FPA. In addition, interested parties may challenge the annual implementation and calculation by our Regulated Operating Subsidiaries of their projected rates and Formula Rate true up pursuant to their approved Formula Rates under the Regulated Operating Subsidiaries’ Formula Rate implementation protocols. End-use consumers and entities supplying electricity to end-use consumers may also attempt to influence government and/or regulators to change the rate setting methodologies that apply to our Regulated Operating Subsidiaries, particularly if rates for delivered electricity increase substantially. If a challenger can establish that any of these aspects are unjust, unreasonable, unduly discriminatory or preferential, then the FERC will make adjustments to them and/or disallow any of our Regulated Operating Subsidiaries’ inclusion of those aspects in the rate setting formula. This could result in lowered rates and/or refunds of amounts collected, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows. See “Rate of Return on Equity Complaints” in Note 17 to the consolidated financial statements for detail on ROE matters.

Our actual capital investment may be lower than planned, which would cause a lower than anticipated rate base and would therefore result in lower revenues, earnings and associated cash flows compared to our current expectations. In addition, we may incur expenses related to the pursuit of strategic investment opportunities, which may be higher than forecasted.

Each of our Regulated Operating Subsidiaries’ rate base, revenues, earnings and associated cash flows are determined in part by additions to property, plant and equipment and when those additions are placed in service. If our operating subsidiaries’ capital investment and the resulting in-service property, plant and equipment are lower than anticipated for any reason, our operating subsidiaries will have a lower than anticipated rate base, thus causing their revenue requirements and future earnings and cash flows to be lower than anticipated.

Any capital investment at our Regulated Operating Subsidiaries may be lower than our published estimates due to, among other factors, the impact of:

•actual or forecasted loads;

•regional economic conditions;

•weather conditions;

•union strikes or labor shortages;

•material and equipment prices and availability;

•variances between estimated and actual costs of construction contracts awarded;

•our ability to obtain financing for such expenditures, if necessary;

•limitations on the amount of construction that can be undertaken on our system or transmission systems owned by others at any one time;

•regulatory requirements relating to our rate construct, including our ability to recover costs;

•the potential for greater competition;

16

•environmental, siting or regional planning issues; and

•legal proceedings.

Our ability to engage in construction projects resulting from pursuing these initiatives is subject to significant uncertainties, including the factors discussed above, and will depend on obtaining any necessary regulatory and other approvals for the project and for us to initiate construction, our achieving status as the builder of the project in some circumstances and other factors. In addition, projects may be canceled, the scope of planned projects may change, or projects may not be completed on time, any of which may adversely affect our level of investment or cause our projected investments to be inaccurate.

In addition, we may incur expenses to pursue strategic investment opportunities. If these payments or expenses are higher than anticipated, our future results of operations, cash flows and financial condition could be materially and adversely affected.

The regulations to which we are subject may limit our ability to raise capital and/or pursue acquisitions, development opportunities or other transactions or may subject us to liabilities.

Each of our Regulated Operating Subsidiaries is a “public utility” under the FPA and, accordingly, is subject to regulation by the FERC. Approval by the FERC is required under Section 203 of the FPA for a disposition or acquisition of regulated public utility facilities, either directly or indirectly through a holding company. Such approval is also required to acquire a significant interest in securities of a public utility. Section 203 of the FPA also provides the FERC with explicit authority over utility holding companies’ purchases or acquisitions of, and mergers or consolidations with, a public utility. Finally, each of our Regulated Operating Subsidiaries must also seek approval by the FERC under Section 204 of the FPA for issuances of its securities (including debt securities). If we are unable to obtain the necessary FERC approvals for potential acquisitions, dispositions or merger activities, or to raise capital, our strategic and growth opportunities may be limited. This could have an adverse impact on our financial condition, results of operations and cash flows.

We are also pursuing development projects for construction of transmission facilities and interconnections with generating resources. These projects may require regulatory approval by Federal agencies, including the FERC, applicable RTOs and state and local regulatory agencies. Failure to secure such regulatory approval for new strategic development projects could adversely affect our ability to grow our business and increase our revenues. If we fail to obtain these approvals when necessary, we may incur liabilities for such failure.

Changes in energy laws, regulations or policies could impact our business, financial condition, results of operations and cash flows.

Each of our Regulated Operating Subsidiaries is regulated by the FERC as a “public utility” under the FPA and is a TO in MISO or SPP. We cannot predict whether the approved rate methodologies for any of our Regulated Operating Subsidiaries will be changed. In addition, the U.S. Congress periodically considers enacting energy legislation that could assign new responsibilities to the FERC, modify provisions of the FPA or provide the FERC or another entity with increased authority to regulate transmission matters. Our Regulated Operating Subsidiaries may be affected by any such changes in federal energy laws, regulations or policies in the future. While our Regulated Operating Subsidiaries are subject to the FERC’s exclusive jurisdiction for purposes of rate regulation, changes in state laws affecting other matters, such as transmission siting and construction, could limit investment opportunities available to us.

Each of our MISO Regulated Operating Subsidiaries depends on its primary customer for a substantial portion of its revenues, and any material failure by those primary customers to make payments for transmission services could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Each of ITCTransmission, METC and ITC Midwest derive a substantial portion of their revenues from the transmission of electricity to the local distribution facilities of DTE Electric, Consumers Energy and IP&L, respectively. Each of these customers is expected to constitute the majority of the revenues of the respective MISO Regulated Operating Subsidiary for the foreseeable future. Any material failure by DTE Electric, Consumers Energy or IP&L to make payments for transmission services could have an adverse effect on our business, financial condition, results of operations and cash flows.

17

A significant amount of the land on which our assets are located is subject to easements, mineral rights and other similar encumbrances. As a result, we must comply with the provisions of various easements, mineral rights and other similar encumbrances, which may adversely impact our ability to complete construction projects in a timely manner.

METC does not own the majority of the land on which its electric transmission assets are located. Instead, under the provisions of the Easement Agreement, METC pays an annual rent to Consumers Energy in exchange for rights-of-way, leases, fee interests and licenses which allow METC to use the land on which its transmission lines are located. Under the terms of the Easement Agreement, METC’s easement rights could be eliminated if METC fails to meet certain requirements, such as paying contractual rent to Consumers Energy in a timely manner. Additionally, a significant amount of the land on which our other subsidiaries’ assets are located is subject to easements, mineral rights and other similar encumbrances. As a result, they must comply with the provisions of various easements, mineral rights and other similar encumbrances, which may adversely impact their ability to complete their construction projects in a timely manner.

We contract with third parties to provide services for certain aspects of our business. If any of these agreements are terminated, we may face a shortage of labor or replacement contractors to provide the services formerly provided by these third parties.

We enter into various agreements and arrangements with third parties to provide services for construction, maintenance and operations of certain aspects of our business, and we utilize the services of contractors to a significant extent. If any of these agreements or arrangements is terminated for any reason, it could result in a shortage of a readily available workforce to provide such services and we may face difficulty finding a qualified replacement workforce. In such a situation, if we are unable to find adequate replacements for contractors in a timely manner, it could have an adverse effect on our results of operations and the ability to carry on our business.

Hazards associated with high-voltage electricity transmission may result in suspension of our operations, costly litigation or the imposition of civil or criminal penalties.

Our operations are subject to the usual hazards associated with high-voltage electricity transmission, including explosions, fires, mechanical failure, unscheduled downtime, equipment interruptions, remediation, chemical spills, discharges or releases of toxic or hazardous substances or gases and other environmental risks. These hazards can cause personal injury and loss of life, severe damage to or destruction of property and equipment and environmental damage, and may result in suspension of operations, litigation by aggrieved parties and the imposition of civil or criminal penalties which may have a material adverse effect on our business, financial condition and results of operations. We are not fully insured against all potential hazards incident to our business, such as damage to poles, towers and lines or losses caused by outages.

A cyber-attack or incident could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Various U.S. Government agencies have noted that external threat sources continue to seek to exploit, through cyber-attacks, potential vulnerabilities in the U.S. energy infrastructure, including electric transmission assets. These cyber threats and attacks are becoming more sophisticated and dynamic. Cybersecurity incidents could harm our business by limiting our transmission capabilities, delay our development and construction of new facilities or capital improvement projects on existing facilities or expose us to liability. Cyber-attacks targeting our information systems could also impair our records, networks, systems and programs, or transmit viruses to other systems. Such events or the threat of such events may increase costs associated with heightened security requirements. In addition, if our major customers or suppliers experience a cyber-attack it may reduce their ability to use our transmission facilities or service our transmission assets. If our business or those of our customers and suppliers are subject to a cyber-attack, it may have a material adverse effect on our business, financial condition, results of operations and cash flows. In addition, laws and regulations governing cybersecurity, data privacy and protection, and the unauthorized disclosure of confidential or protected information pose increasingly complex compliance challenges and potentially elevate costs, and any failure to comply with these laws and regulations could result in significant penalties and legal liability.

18

We are subject to environmental regulations and to laws that can give rise to substantial liabilities from environmental contamination.

We are subject to federal, state and local environmental laws and regulations, which impose limitations on the discharge of pollutants into the environment, establish standards for the management, treatment, storage, transportation and disposal of solid and hazardous wastes and hazardous materials, and impose obligations to investigate and remediate contamination in certain circumstances. Liabilities relating to investigation and remediation of contamination, as well as other liabilities concerning hazardous materials or contamination such as claims for personal injury or property damage, may arise at many locations, including formerly owned or operated properties and sites where wastes have been treated or disposed of, as well as properties we currently own or operate. Such liabilities may arise even where the contamination does not result from noncompliance with applicable environmental laws. Under a number of environmental laws, such liabilities may also be joint and several, meaning that a party can be held responsible for more than its share of the liability involved, or even the entire share.

We may be required to incur significant unanticipated expenses in connection with environmental compliance. Failure to comply with the extensive environmental laws and regulations applicable to us could result in significant civil or criminal penalties and remediation costs. Our assets and operations also involve the use of materials classified as hazardous, toxic or otherwise dangerous. Some of our facilities and properties are located near environmentally sensitive areas such as wetlands and habitats of endangered or threatened species. In addition, certain properties in which we operate are, or are suspected of being, affected by environmental contamination. Compliance with these laws and regulations, and liabilities concerning contamination or hazardous materials, may adversely affect our costs and, therefore, our business, financial condition and results of operations.

If amounts billed for transmission service for our Regulated Operating Subsidiaries’ transmission systems are lower than expected, or our actual revenue requirements are higher than expected, the timing of actual collection of our total revenues would be delayed.

If amounts billed for transmission service are lower than expected, the timing of actual collections of our Regulated Operating Subsidiaries’ total revenue requirement would likely be delayed until such circumstances are adjusted through the true-up mechanism, which would be settled within a two-year period, in our Regulated Operating Subsidiaries’ Formula Rates. Lower than expected amounts collected could result from lower network load or point-to-point transmission service on our Regulated Operating Subsidiaries’ transmission systems due to a weak economy, changes in the nature or composition of the transmission assets of our Regulated Operating Subsidiaries and surrounding areas, poor transmission quality of neighboring transmission systems, or for any other reason. In addition, if the revenue requirements of our Regulated Operating Subsidiaries are higher than expected, the timing of actual collection of our Regulated Operating Subsidiaries' total revenue requirements would likely be delayed until such circumstances are reflected through the true-up mechanism, which would be settled within a two-year period, in our Regulated Operating Subsidiaries' Formula Rates. This could be due to higher actual expenditures compared to the forecasted expenditures used to develop their billing rates or for any other reason. The effect of such under-collection would be to reduce the amount of our available cash resources from what we had expected, until such under-collection is corrected through the true-up mechanism in the Formula Rate template, which may require us to increase our outstanding indebtedness, thereby reducing our available borrowing capacity, and may require us to pay interest at a rate that exceeds the interest to which we are entitled in connection with the operation of the true-up mechanism.

The physical effects of climate change, including natural disasters, severe weather and other related phenomena, and the regulatory and legislative developments related to climate change, may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Natural disasters, severe weather, and other related phenomena, primarily in the form of thunderstorms, flooding, wildfires, hurricanes, storm surges, atmospheric rivers and snow, ice storms, wind events or droughts, due to climate change, and the frequency and severity thereof, may negatively affect our business and financial condition through increased costs from (i) repairs to our transmission facilities, (ii) implementation of contingency plans for continued operations as repairs are underway and (iii) fluctuating energy use by customers, which may require us to invest in additional assets. We could also experience disruptions to our supply chain, as our suppliers may face similar challenges to their operations from such weather-related events due to climate change. Furthermore, prolonged power outages to customers and business interruptions from

19

delays in storm restoration efforts could damage our reputation, which may have a material adverse effect on our business, financial condition, results of operations and cash flows. Longer-term climate change impacts, such as sustained higher temperatures, higher sea levels, larger storm surges and floods, could result in service disruption, shortened asset life, increased repair and replacement costs, and costs associated with strengthened design standards and systems.

In addition to the physical effects of climate change, federal, regional or state legislative or regulatory bodies have attempted, and may in the future attempt, to introduce requirements or incentives to reduce peak demand and energy consumption or control or limit the causes of climate change, including greenhouse gas emissions, such as carbon dioxide and methane. Resulting programs, laws or regulations could lead to load reduction, or impose costs tied to greenhouse gas emissions, operational requirements or restrictions, or additional charges to fund energy efficiency activities or conservation measures. They could also provide a cost advantage to alternative energy sources or result in other costs or requirements, such as costs associated with the adoption of new infrastructure and technology to respond to new mandates. The occurrence of the foregoing events could put upward pressure on costs, adversely affecting our business, financial condition, results of operations and cash flows.

We are subject to various regulatory requirements, including reliability standards; contract filing requirements; reporting, recordkeeping and accounting requirements; and transaction approval requirements. Violations of these requirements, whether intentional or unintentional, may result in penalties that, under some circumstances, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The various regulatory requirements to which we are subject include reliability standards established by the NERC, which operates as the nation’s Electric Reliability Organization approved by the FERC in accordance with Section 215 of the FPA. These standards address operation, planning and security of the bulk power system, including requirements with respect to real-time transmission operations, emergency operations, vegetation management, critical infrastructure protection and personnel training. Failure to comply with these requirements can result in monetary penalties as well as non-monetary sanctions. Monetary penalties vary based on an assigned risk factor for each potential violation, the severity of the violation and various other circumstances, such as whether the violation was intentional or concealed, whether there are repeated violations, the degree of the violator’s cooperation in investigating and remediating the violation and the presence of a compliance program, and such penalties can be substantial. Non-monetary sanctions include potential limitations on the violator’s activities or operations and placing the violator on a watchlist for major violators. If any of our subsidiaries violate the NERC reliability standards, even unintentionally, in any material way, any penalties or sanctions imposed against us could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Certain of our subsidiaries are also subject to requirements under Sections 203 and 205 of the FPA for approval of transactions; reporting, recordkeeping and accounting requirements; and for filing contracts related to the provision of jurisdictional services. Under FERC policy, failure to file jurisdictional agreements on a timely basis may result in foregoing the time value of revenues collected under the agreement, but not to the point where a loss would be incurred. The failure to obtain timely approval of transactions subject to FPA Section 203, or to comply with applicable reporting, recordkeeping or accounting requirements under FPA Section 205, could subject us to penalties that could have a material adverse effect on our financial condition, results of operations and cash flows.

Changes in tax laws or regulations may negatively affect our financial condition, results of operations, net income, cash flows and credit metrics.

We are subject to taxation by various taxing authorities at the federal, state and local levels. Various representatives of the government, corporations, industry groups and the public continue to pursue changes to tax laws and regulations, and corporate tax reform continues to be a priority in many jurisdictions. Due to unique aspects of the treatment of taxes for regulated utilities, the impacts of changes in tax laws for us and our Regulated Operating Subsidiaries may differ from the impacts to other corporations generally. Changes in federal, state or local tax rates or other aspects of tax laws could materially and adversely affect our financial condition, results of operations, net income, cash flows, and credit metrics.

20

The widespread outbreak of an illness or other communicable disease, or any other public health crisis, could have a material adverse impact on our business, financial condition, results of operations, cash flows and credit metrics.

We could be negatively impacted by the widespread outbreak of an illness or other communicable disease, or other public health crisis, that results in economic and trade disruptions, including the disruption of global supply chains. As a result of efforts to limit the spread of communicable diseases, public health authorities, OSHA, and/or the states served by our transmission systems may issue orders that can place restrictions on and/or result in the temporary shutdown of operations of businesses that use our transmission systems. Moreover, we may be required to comply with obligations enacted by relevant authorities to help prevent the spread of illness or disease, which poses the risk of workforce disruption that could impact business continuity. The impact of efforts to limit the spread of illness or disease on our business, financial condition and results of operations may be material and adverse and may depend on various factors. These factors may include the duration and severity of the illness or disease, the length and magnitude of any business restrictions that are enacted and the efficacy of other efforts to prevent the spread of the disease, such as vaccines.

The widespread outbreak of an illness or disease could also disrupt the supply chains that provide services and equipment to us as part of our capital expenditures or maintenance efforts. If our supply chains are disrupted, we may be unable to perform necessary maintenance, which could result in increased costs as we implement contingency plans to allow us to continue to operate. Supply chain interruptions may also increase the cost of capital expenditures or result in the delay or cancellation of planned projects, any of which could have a material adverse impact on our business, financial condition, results of operations and cash flows.

We require access to the capital markets to fund capital investments. If access to the capital markets is adversely affected by any widespread illness or disease, we may need to consider alternative sources of funding for our operations and for working capital, any of which may not be available and may increase our cost of capital. An extended period of disruption to the economy, our workforce, supply chains or capital markets due to the widespread outbreak of an illness or disease could materially impact our business, financial condition, results of operations, cash flows and credit metrics.

Acts of war, terrorist attacks and other catastrophic events may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Acts of war, terrorist attacks and other catastrophic events may negatively affect our business, financial condition and cash flows in unpredictable ways, such as increased security measures and disruptions of markets and supply chains. Energy related assets, including, for example, our transmission facilities and DTE Electric’s, Consumers Energy’s and IP&L’s generation and distribution facilities that we interconnect with, may be at risk of acts of war, terrorist attacks and other catastrophic events. Such events or threats may have a material effect on the economy in general and could result in a decline in energy consumption, which may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Advances in technology may negatively impact our business, financial condition, results of operations and cash flows.

Research and development efforts continue to seek improvements to existing or new alternative technologies to produce, store and distribute power, including fuel cells, microturbines, distributed generation and battery storage. It is possible that adoption of such alternative technologies could be significant enough to cause a reduction in the demand for electricity from the traditional bulk electric system or could make portions of our transmission systems obsolete before the end of their useful lives. Such advances in alternative technologies could decrease the need for capital investments in our transmission systems over time or increase cost, and as a result could have an adverse effect on our business, financial condition, results of operations and cash flows.

Risks Relating to Our Corporate and Financial Structure

ITC Holdings is a holding company with no operations, and unless we receive dividends or other payments from our subsidiaries, we may be unable to fulfill our cash obligations.

As a holding company with no business operations, ITC Holdings’ material assets consist primarily of the stock and membership interests in our subsidiaries. Our primary sources of cash to meet our obligations are dividends and other payments received by us from time to time from our subsidiaries, the proceeds raised from

21

the sale of our securities and borrowings under our various credit agreements. Each of our subsidiaries, however, is legally distinct from us and has no obligation, contingent or otherwise, to make funds available to us. The ability of each of our Regulated Operating Subsidiaries and our other subsidiaries to pay dividends and make other payments to us is subject to, among other things, the availability of funds, after taking into account capital expenditure requirements, the terms of its indebtedness, applicable state laws and regulations of the FERC and the FPA. Our Regulated Operating Subsidiaries target a FERC-approved capital structure of 60% equity and 40% debt that may limit the ability of our Regulated Operating Subsidiaries to use net assets for the payment of dividends to ITC Holdings. In addition, ITC Holdings’ right to receive any assets of any subsidiary, and therefore the right of its creditors to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors. If ITC Holdings does not receive cash or other assets from our subsidiaries, it may be unable to pay principal and interest on its indebtedness.

We have a considerable amount of debt and our reliance on debt financing may limit our ability to fulfill our debt obligations and/or to obtain additional financing.

We have a considerable amount of debt and our consolidated indebtedness may include various debt securities and borrowings, which utilize indentures, revolving and term loan credit agreements and commercial paper that we rely on as sources of capital and liquidity. Our capital structure can have several important consequences, including, but not limited to, the following:

•If future cash flows are insufficient, we may not be able to make principal or interest payments on our debt obligations, which could result in the occurrence of an event of default under one or more of those debt instruments.

•We may need to increase our indebtedness in order to make the capital expenditures and other expenses or investments planned by us.

•Our indebtedness has the general effect of reducing our flexibility to react to changing business and economic conditions insofar as they affect our financial condition. A substantial portion of the dividends and payments in lieu of taxes we receive from our subsidiaries will be dedicated to the payment of interest on our indebtedness, thereby, reducing our available cash.

•In the event that we are liquidated, the creditors of our subsidiaries will be entitled to payment in full of the subsidiaries’ indebtedness prior to making any payments to ITC Holdings for the payment of its indebtedness.

•We currently have debt instruments outstanding with short-term maturities or relatively short remaining maturities. Our ability to secure additional financing prior to or after these facilities mature, if needed, may be substantially restricted by the existing level of our indebtedness and the restrictions contained in our debt instruments. Additionally, the interest rates at which we might secure additional financings may be higher than our currently outstanding debt instruments or higher than forecasted at any point in time, which could adversely affect our business, financial condition, results of operations and cash flows.

•Market conditions could affect our access to capital markets, restrict our ability to secure financing to make the capital expenditures and investments and pay other expenses planned by us which could adversely affect our business, financial condition, results of operations and cash flows.

We may incur substantial additional indebtedness in the future. The incurrence of additional indebtedness would increase the leverage-related risks described above.

Adverse changes in our credit ratings may negatively affect us.

Our ability to access capital markets is important to our ability to operate our business. Increased scrutiny of the energy industry and the impact of regulation, as well as changes in our financial performance and unfavorable conditions in the capital markets could result in credit agencies reexamining and downgrading our credit ratings. In addition, because we are a subsidiary of Fortis, a downgrade in Fortis’ credit rating could cause our credit rating to be downgraded as well, even if our creditworthiness has not otherwise deteriorated. A downgrade in our credit ratings could restrict or discontinue our ability to access capital markets at attractive rates and increase our borrowing costs. A rating downgrade could also increase the interest we pay on our debt instruments.

22

Certain provisions in our debt instruments limit our financial and operating flexibility.

Our debt instruments on a consolidated basis, which may include senior notes, secured notes, first mortgage bonds, revolving and term loan credit agreements and commercial paper, contain numerous financial and operating covenants that place significant restrictions on, among other things, our ability to:

•incur additional indebtedness;

•engage in sale and lease-back transactions;

•create liens or other encumbrances;

•enter into mergers, consolidations, liquidations or dissolutions, or sell or otherwise dispose of all or substantially all of our assets;

•create and acquire subsidiaries; and

•pay dividends or make distributions on our stock or on the stock or member capital of our subsidiaries.

In addition, the covenants require us to meet certain financial ratios, such as maintaining certain debt to capitalization ratios and certain funds from operations to debt levels. Our ability to comply with these and other requirements and restrictions may be affected by changes in economic or business conditions, results of operations or other events beyond our control. A failure to comply with the obligations contained in any of our debt instruments could result in acceleration of related debt and the acceleration of debt under other instruments evidencing indebtedness that may contain cross-acceleration or cross-default provisions.

ITEM 1B.     UNRESOLVED STAFF COMMENTS.

None.

ITEM 1C.     CYBERSECURITY.

In response to cybersecurity threats to our business, which include threats to our operations, critical infrastructure assets, information systems and data, we have developed a comprehensive cybersecurity risk management program.

Governance

Primary responsibility for assessing, monitoring, and managing our cybersecurity risks is overseen by our Chief Information Officer (CIO). Our CIO has maintained certification as a Certified Information Security Manager since 2006 and brings extensive experience in information technology and in-depth knowledge in developing and executing our cybersecurity strategies. At the direction of the Board of Directors, our management has developed a cybersecurity policy which includes the establishment of, and ongoing monitoring by, a cybersecurity steering committee led by the CIO and comprised of executives from key departments, including legal, finance, accounting, operations, engineering and human resources. The committee meets quarterly and on an as-needed basis and is charged with overseeing and assisting the information technology department in directing cybersecurity activities to protect the Company, including its operations, systems and related information. It also oversees and reviews policies, procedures, and internal controls for cybersecurity as well as the cybersecurity risk management program.

Given the importance to our business and the heightened risk, the Board of Directors provides oversight of management’s response to cybersecurity risks. Management, including our CIO, provides the Board of Directors periodic updates on cybersecurity, including updates on cyber goals, cybersecurity risks, and related risk mitigation strategies. As part of our enterprise risk management process, an annual risk assessment is completed by a cross-functional group of management led by our finance department, and includes members of our information technology department for the cybersecurity assessment section. The results of the risk assessment, as well as mitigation strategies, are discussed with the Board of Directors.

Risk Management and Strategy

In addition to the enterprise risk management process, we utilize an additional cybersecurity risk management process that assesses the risks and protections of several key assets within the organization. As a result of these assessments and as the threat landscape becomes increasingly sophisticated, we continue to evolve our defensive strategy by deploying new technology, continuing education of our user community, and

23

advancing our protections against ongoing cybersecurity risks and threats. We leverage threat intelligence and external industry practices for continuous improvement and refinement of our cybersecurity program.

Given the regulatory framework under which we operate, we follow a cybersecurity incident response plan that is tested annually in compliance with NERC’s critical infrastructure protection standards and includes external disclosure procedures. This plan identifies the members of our cybersecurity incident response team and the criteria to identify, classify and respond to a cybersecurity incident. Cybersecurity incidents are communicated to internal stakeholders, such as management and the Board of Directors, and external stakeholders based on severity of the incident in accordance with the cybersecurity response plan.

Our CIO oversees a team of cybersecurity professionals in the cyber security operations center with certifications in cybersecurity engineering and cybersecurity operational areas. We also utilize internal audits to periodically assess the effectiveness of our cybersecurity processes and external parties to periodically conduct threat and vulnerability assessments. We continue to invest in training for all employees, including training for our cybersecurity professionals on the specific technologies utilized within the company and development of these individuals to keep their knowledge current. Additionally, we have a vendor risk management program to review and assess cybersecurity risks related to utilizing information technology vendor products and services for new and existing vendors that is subject to ongoing monitoring.

We are not aware of any cybersecurity incidents that have materially affected, or are reasonably likely to materially affect the Company, our business strategy, results of operations or financial condition.

ITEM 2.    PROPERTIES.

Our Regulated Operating Subsidiaries’ transmission facilities are located in Michigan, Iowa, Minnesota, Illinois, Missouri, Kansas, Oklahoma and Wisconsin. Our Regulated Operating Subsidiaries have agreements with other utilities for the joint ownership of specific substations, transmission lines and other transmission assets. See Note 15 to the consolidated financial statements for more information on the jointly owned assets.

Overview

ITC Holdings provides safe and reliable electric transmission service to connect consumers to more sustainable and cost-effective energy resources. ITC Holdings continues to make investments in a modernized grid to maintain reliability and accommodate future demands as lifestyles and the economy become increasingly dependent on electricity.

26

Our business consists primarily of the electric transmission operations of our Regulated Operating Subsidiaries. Through our Regulated Operating Subsidiaries, we own, operate, maintain and invest in high-voltage transmission systems in Michigan’s Lower Peninsula and portions of Iowa, Minnesota, Illinois, Missouri, Kansas, Oklahoma and Wisconsin that transmit electricity from generating stations to local distribution facilities connected to our transmission systems.

Our Regulated Operating Subsidiaries’ primary operating responsibilities include maintaining, improving and expanding their transmission systems to meet their customers’ ongoing needs, scheduling outages on system elements to allow for maintenance and construction, maintaining appropriate system voltages and monitoring flows over transmission lines and other facilities to ensure physical limits are not exceeded.

Our Regulated Operating Subsidiaries earn revenues for the use of their electric transmission systems by their customers, which include investor-owned utilities, municipalities, cooperatives, power marketers and alternative energy suppliers. As independent transmission companies, our Regulated Operating Subsidiaries are subject to rate regulation only by the FERC, and our cost-based rates are discussed below under “— Cost-Based Formula Rates with True-Up Mechanism” as well as in Note 6 to the consolidated financial statements.

Significant recent matters that influenced our financial condition, results of operations and cash flows for the year ended December 31, 2023 or that may affect future results include:

•Our capital expenditures of $818 million at our Regulated Operating Subsidiaries during the year ended December 31, 2023, as described below under “— Capital Investment and Operating Results Trends;”

•Debt issuances, borrowings and repayments, and changes to debt agreements and derivative instruments as described in Note 9 to the consolidated financial statements;

•Rulings from the Iowa Supreme Court and Iowa District Court for Polk County on ROFR proceedings, as described below under “ — Recent Developments;”

•The August 2022 D.C. Circuit Court decision related to the MISO ROE Complaints, as described in Note 17 to the consolidated financial statements;

•NOPRs previously issued by the FERC proposing changes to transmission incentives policy (as described in Note 6 to the consolidated financial statements), regional transmission planning and cost allocation; and

•The final rule issued by the FERC on July 28, 2023 proposing changes to generator interconnection procedures, which we are monitoring for additional developments related to appeals but is not expected to have a significant impact on our financial condition, results of operations or cash flows.

Certain of these items are discussed in more detail throughout “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Recent Developments

Iowa State Tax Rate Change

On March 1, 2022, the governor of Iowa signed an act into law that contains provisions to reduce Iowa’s corporate tax rates if a certain threshold of the state’s annual net corporate income tax receipts is met. Adjustments to reduce the corporate income tax rate are calculated annually after the end of each fiscal year and may continue until the currently targeted corporate income tax rate of 5.5% is reached.

For Iowa’s fiscal year ended June 30, 2023, net corporate income tax receipts exceeded the prescribed threshold. On September 22, 2023, the Iowa Department of Revenue certified a reduction in the top corporate income tax rate from 8.4% to 7.1%, effective January 1, 2024. We have revalued certain deferred tax balances and net operating losses impacted by the change in the future Iowa corporate income tax rate. As a result, deferred income tax expense of $6 million was recorded during the year ended December 31, 2023. In addition, a regulatory liability of $21 million was recorded as of December 31, 2023 to offset deferred taxes associated with rate base at ITC Midwest. See Note 10 to the consolidated financial statements for additional information related to the Iowa corporate income tax rate reductions.

Iowa Courts’ Rulings on Right of First Refusal

In 2020, the State of Iowa enacted a state law that grants incumbent Iowa electric transmission owners, including ITC Midwest, a ROFR to construct, own and maintain certain electric transmission assets in the state. On October 14, 2020, LS Power Midcontinent, LLC and Southwest Transmission, LLC sued the Iowa Utilities Board and several individual defendants, seeking a judgment that the ROFR provisions violated the Iowa Constitution and requesting a temporary injunction of the ROFR until the case was resolved. The case was dismissed in district court based on the plaintiffs’ lack of standing in the case and the court of appeals later affirmed the district court’s ruling.

Following appeal, on March 24, 2023, the Iowa Supreme Court issued an opinion that the plaintiffs have standing to challenge the ROFR provision, thereby vacating the decision of the court of appeals, reversing the district court’s judgment and remanding the case to the Iowa District Court for Polk County to determine the merits regarding the constitutionality of the ROFR statute. As part of this opinion, the Iowa Supreme Court also issued a temporary injunction staying the enforcement of the ROFR. However, ITC Midwest has already exercised its right to construct certain electric transmission projects approved and awarded by MISO, including projects approved by MISO in 2022 as part of the first tranche of LRTP projects.

On December 4, 2023, the Iowa District Court for Polk County issued a decision finding that the manner in which Iowa’s ROFR statute was passed is unconstitutional. The court did not make any determination on the merits of the ROFR itself. The district court issued a permanent injunction preventing ITC Midwest and others from taking further action to construct the first tranche of Iowa’s LRTP projects in reliance on the ROFR. However, the district court stated that the injunction does not prohibit ITC Midwest from seeking approval from the State of Iowa to move forward with the first tranche of LRTP projects in a manner that does not rely on the ROFR statute. ITC Midwest has filed for reconsideration of the district court’s decision with respect to the scope of the injunction. We are assessing next steps in the Iowa ROFR proceedings and, until there is more certainty around the resolution of these matters, we cannot predict the impact to amounts or timing of future capital expenditures of ITC Midwest related to the first tranche of Iowa LRTP projects.

Capital Structure Complaint

On May 10, 2022, the Iowa Coalition for Affordable Transmission, including IP&L, filed a complaint with the FERC under Section 206 of the FPA. Specifically, the complaint alleged that ITC Midwest does not meet the FERC’s three-part test for authorizing the use of a utility’s actual capital structure for ratemaking purposes which requires that ITC Midwest 1) issue its own debt without guarantees, 2) have its own credit rating, and 3) have a capital structure within the range of capital structures previously approved by the Commission. The Iowa Coalition for Affordable Transmission asked the FERC to reduce ITC Midwest’s equity component from 60% to 53%. On November 2, 2022, the FERC issued an order denying the complaint. On December 2, 2022, the Iowa Coalition for Affordable Transmission filed a request for rehearing with the FERC. On March 16, 2023, the FERC confirmed the previous order denying the complaint and we consider the matter to be closed.

Cost-Based Formula Rates with True-Up Mechanism

Our Regulated Operating Subsidiaries calculate their revenue requirements using cost-based Formula Rates that are effective without the need to file rate cases with the FERC, although the rates are subject to legal challenge at the FERC. Under their cost-based formula, each of our Regulated Operating Subsidiaries separately calculates a revenue requirement based on financial information specific to each company. The calculation of projected revenue requirement for a future period is used to establish the transmission rate used for billing purposes. The calculation of actual revenue requirements for a historic period is used to calculate the amount of revenues recognized in that period and determine the over- or under-collection for that period.

Under these Formula Rates, our Regulated Operating Subsidiaries recover expenses and earn an authorized return on and recover investments in property, plant and equipment on a current basis. The Formula Rates for a given year reflect forecasted expenses, property, plant and equipment, point-to-point revenues, network load at our MISO Regulated Operating Subsidiaries and other items for the upcoming calendar year to establish projected revenue requirements for each of our Regulated Operating Subsidiaries that are used as the basis for billing for service on their systems from January 1 to December 31 of that year. Our Formula Rates include a true-up mechanism, whereby our Regulated Operating Subsidiaries compare their actual revenue requirements to their billed revenues for each year to determine any over- or under-collection of revenue. The over- or under-collection typically results from differences between the projected revenue requirement used as

28

the basis for billing and actual revenue requirement at each of our Regulated Operating Subsidiaries, or from differences between actual and projected monthly network peak loads at our MISO Regulated Operating Subsidiaries. In the event billed revenues in a given year are more or less than actual revenue requirements, which are calculated primarily using information from that year’s FERC Form No. 1, our Regulated Operating Subsidiaries will refund or collect additional revenues, with interest, within a two-year period such that customers pay only the amounts that correspond to actual revenue requirements for that given period. This annual true-up ensures that our Regulated Operating Subsidiaries recover their allowed costs and earn their authorized returns.

See “Cost-Based Formula Rates with True-Up Mechanism” in Note 6 to the consolidated financial statements for further discussion of our Formula Rates and see “Rate of Return on Equity Complaints” in Note 17 to the consolidated financial statements for detail on ROE matters.

Revenue Accruals and Deferrals — Effects of Monthly Network Peak Loads

For our MISO Regulated Operating Subsidiaries, monthly network peak loads are used for billing network revenues, which currently is the largest component of our operating revenues. One of the primary factors that impacts the revenue accruals and deferrals at our MISO Regulated Operating Subsidiaries is actual monthly network peak loads experienced as compared to those forecasted in establishing the annual network transmission rate. Under their cost-based Formula Rates that contain a true-up mechanism, our MISO Regulated Operating Subsidiaries accrue or defer revenues to the extent that their actual revenue requirement for the reporting period is higher or lower, respectively, than the amounts billed relating to that reporting period. Although monthly network peak loads do not impact operating revenues recognized, network load affects the timing of our cash flows from transmission service. The monthly network peak load of our MISO Regulated Operating Subsidiaries is generally impacted by weather, economic conditions and other significant factors and is seasonally shaped with higher load in the summer months when cooling demand is higher. We are unable to predict the possible future impacts of weather, economic conditions and other factors on monthly network peak loads at our MISO Regulated Operating Subsidiaries.

29

ITC Great Plains does not receive revenue based on a peak load or a dollar amount per kW each month. Therefore, peak load does not have a seasonal effect on operating cash flows. The SPP tariff applicable to ITC Great Plains is billed ratably each month based on its annual projected revenue requirement posted annually by SPP.

Capital Investment and Operating Results Trends

We expect a long-term upward trend in rate base resulting from our anticipated capital investment, in excess of depreciation and any acquisition premiums, from our Regulated Operating Subsidiaries’ long-term capital investment programs to improve reliability, increase system capacity and upgrade the transmission network to support new generating resources. Investments in property, plant and equipment, when placed in-service upon completion of a capital project, are added to the rate base of our Regulated Operating Subsidiaries. We expect increases in rate base to result in a corresponding long-term upward trend in revenues and earnings. Our revenues and earnings may be impacted by future increases or decreases to our rates for incentive adders and base ROE. As of December 31, 2023, our Regulated Operating Subsidiaries had a total of approximately $5 billion of equity in their collective capital structures for ratemaking purposes. Based on this level of aggregate equity, we estimate that each 10 basis point change in the authorized ROE would impact annual consolidated net income by approximately $5 million. See Note 6 and Note 17 to the consolidated financial statements for additional information related to matters that may impact future rates for incentive adders and base ROE.

Our Regulated Operating Subsidiaries incur significant costs to invest in their transmission systems and maintain the assets on their systems. While we have been impacted by increases in inflation and supply chain disruptions, these challenges have not had a material impact on our current or forecasted capital expenditures. We work closely with our suppliers to manage costs and deliveries of required materials and supplies and attempt to ensure that our asset and inventory purchases adequately support our construction and maintenance activities. In response to these challenges, we have increased levels of certain materials and supplies inventories over time to help reduce risks related to global supply chain constraints. We continue to evaluate and monitor the potential impacts of these macroeconomic trends on our forecasted capital expenditures and maintenance activities.

Our Regulated Operating Subsidiaries strive for high reliability of their systems and improvement in system accessibility for all generation resources. The FERC requires compliance with certain reliability standards and may take enforcement actions against violators, including the imposition of substantial fines. NERC is responsible for developing and enforcing these mandatory reliability standards. We continually assess our transmission systems against standards established by NERC, as well as the standards of applicable regional entities under NERC that have been delegated certain authority for the purpose of proposing and enforcing reliability standards. We believe that we meet the applicable standards in all material respects, although further investment in our transmission systems and an increase in maintenance activities will likely be needed to maintain compliance, improve reliability and address any new standards that may be promulgated.

We also assess our transmission systems against our own planning criteria that are filed annually with the FERC. Based on our planning studies, we see needs to make capital investments to: (1) maintain and replace our current transmission infrastructure to enhance system reliability and accommodate load growth; (2) interconnect new renewable generation resources; (3) upgrade physical and technological grid security to protect critical infrastructure; and (4) expand access to electricity markets to reduce the overall cost of delivered energy to customers.

In addition to future investments identified through our planning studies, MISO is working to identify capital investment needs through its LRTP initiative. The objective of this initiative is to ensure grid reliability while integrating the different operating characteristics of new generation resources and increase resiliency of the grid during severe weather events. MISO has identified a number of projects in the first tranche of this plan that will

30

result in additional capital investments across MISO’s Midwest subregion through 2030. The following table shows our actual and expected capital expenditures at our Regulated Operating Subsidiaries:

	Actual Capital		Forecasted
	Expenditures for the		Capital
	year ended		Expenditures
(In millions of USD)	December 31, 2023		2024 — 2028 (b)
Expenditures for property, plant and equipment (a)	$	818	$	5,530

____________________________

(a)Amounts represent the cash payments to acquire or construct property, plant and equipment, as presented in the consolidated statements of cash flows. These amounts exclude non-cash additions to property, plant and equipment for the AFUDC equity as well as accrued liabilities for construction, labor and materials that have not yet been paid.

(b)Includes approximately $1.2 billion of investments related to the first tranche of projects in MISO’s LRTP, of which approximately $900 million are related to projects located in Iowa. The decision for assignment of the LRTP projects was finalized on July 25, 2022. MISO is the only entity charged with determining what projects are to be competitively bid pursuant to its tariff. We believe it is unlikely that MISO will change this designation. Further, under the MISO tariff approximately 70% of ITC Midwest’s first tranche of projects are upgrades to existing ITC Midwest facilities in Iowa along existing rights of way, which under MISO’s tariff grants ITC Midwest the option to construct the upgrades regardless of the outcome of the ROFR legislation. For any portion of the first tranche of MISO’s LRTP projects in Iowa to be competitively bid, we believe it would require a federal decision that significantly departs from existing rules under the MISO tariff.

Our long-term growth plan includes ongoing investments in our current regulated transmission systems and the identification of incremental strategic projects primarily located in and around our service territories. Refer to “Item 1. Business — Development of Business” for additional information.

Investments in property, plant and equipment could be lower than expected due to a variety of factors, as discussed in “Item 1A. Risk Factors.” In addition, investments in transmission network upgrades for generator interconnection projects could change from prior estimates significantly due to changes in the MISO queue for generation projects and other factors beyond our control.

Significant Components of Results of Operations

Revenues

We derive nearly all of our revenues from providing transmission, scheduling, control and dispatch services and other related services over our Regulated Operating Subsidiaries’ transmission systems to DTE Electric, Consumers Energy, IP&L and other entities, such as alternative energy suppliers, power marketers and other wholesale customers that provide electricity to end-use consumers, as well as from transaction-based capacity reservations on our transmission systems. MISO and SPP are responsible for billing and collecting the majority of transmission service revenues. As the billing agents for our MISO Regulated Operating Subsidiaries and ITC Great Plains, MISO and SPP collect fees for the use of our transmission systems, invoicing DTE Electric, Consumers Energy, IP&L and other customers on a monthly basis.

Network Revenues are generated from network customers for their use of our electric transmission systems and are based on the actual revenue requirements as a result of our accounting under our cost-based Formula Rates that contain a true-up mechanism. Refer below under “— Critical Accounting Estimates — Revenue Recognition under Cost-Based Formula Rates with True-Up Mechanism” for a discussion of revenue recognition relating to network revenues.

Network revenues from ITC Great Plains include the annual revenue requirements specific to projects that are charged exclusively within one pricing zone within SPP or are classified as direct assigned network upgrades under the SPP tariff and contain a true-up mechanism.

Regional Cost Sharing Revenues are generated from transmission customers throughout RTO regions for their use of our MISO Regulated Operating Subsidiaries’ network upgrade projects that are eligible for regional cost sharing under provisions of the MISO tariff. Additionally, certain projects at ITC Great Plains are eligible for recovery through a region-wide charge under provisions of the SPP tariff. Regional cost sharing revenues are treated as a reduction to the net network revenue requirement under our cost-based Formula Rates.

31

Point-to-Point Revenues consist of revenues generated from a type of transmission service for which the customer pays for transmission capacity reserved along a specified path between two points on an hourly, daily, weekly or monthly basis. Point-to-point revenues also include other components pursuant to schedules under the MISO and SPP transmission tariffs. Point-to-point revenues are treated as a revenue credit to network or regional customers and are a reduction to gross revenue requirement when calculating net revenue requirement under our cost-based Formula Rates.

Scheduling, Control and Dispatch Revenues are allocated to our MISO Regulated Operating Subsidiaries by MISO as compensation for the services performed in operating the transmission system. Such services include monitoring of reliability data, current and next day analysis, implementation of emergency procedures and outage coordination and switching.

Other Revenues consist of rental revenues, easement revenues, revenues relating to utilization of jointly owned assets under our transmission ownership and operating agreements and amounts from providing ancillary services to customers. The majority of other revenues are treated as a revenue credit and taken as a reduction to gross revenue requirement when calculating net revenue requirement under our cost-based Formula Rates.

Operating Expenses

Operation and Maintenance Expenses consist primarily of the costs for contractors that operate and maintain our transmission systems as well as our personnel involved in operation and maintenance activities.

Operation expenses include activities related to control area operations, which involve balancing loads and generation and transmission system operations activities, including monitoring the status of our transmission lines and stations. Rental expenses relating to land easements, including METC’s Easement Agreement, are also recorded within operation expenses.

Maintenance expenses include preventive or planned activities, such as vegetation management, tower painting and equipment inspections, as well as reactive maintenance for equipment failures.

General and Administrative Expenses consist primarily of costs for personnel in our legal, information technology, finance, regulatory, human resources, community relations and communication and other support functions, general office expenses and fees for professional services. Professional services are principally composed of outside legal, consulting, audit and information technology services.

Depreciation and Amortization Expenses consist primarily of depreciation of property, plant and equipment using the straight-line method of accounting. Additionally, this consists of amortization of various regulatory and intangible assets.

Taxes Other than Income Taxes consist primarily of property taxes and payroll taxes.

Other Items of Income or Expense

Interest Expense consists primarily of interest on debt at ITC Holdings and our Regulated Operating Subsidiaries. Additionally, the amortization of debt financing expenses are recorded to interest expense. An allowance for borrowed funds used during construction is included in property, plant and equipment accounts and treated as a reduction to interest expense. The amortization of gains and losses on settled and terminated derivative financial instruments is recorded to interest expense.

Allowance for Equity Funds Used During Construction (“AFUDC equity”) is recorded as an item of other income and is included in property, plant and equipment accounts. The allowance represents a return on equity at our Regulated Operating Subsidiaries used for construction purposes in accordance with the FERC regulations. The capitalization rate applied to the construction work in progress balance is based on the proportion of equity to total capital (which currently includes equity and long-term debt) and the authorized return on equity for our Regulated Operating Subsidiaries.

Income Tax Provision

Income tax provision consists of current and deferred federal and state income taxes.

____________________________

(a)Includes a portion of Formula Rate true-up revenue.

Operating revenues increased primarily due to higher rate base associated with higher balances of property, plant and equipment in service and resulting return. Other contributors included increased recoverable operating expenses.

33

Other Expenses (Income)

Interest expense, net

Interest expense, net increased for the year ended December 31, 2023 compared to the year ended December 31, 2022 due to higher overall debt balances and higher interest rates on long-term debt issuances, commercial paper and our revolving credit agreements. See Note 9 to the consolidated financial statements for additional information.

Allowance for equity funds used during construction

AFUDC equity increased for the year ended December 31, 2023 compared to the year ended December 31, 2022 due primarily to higher balances of construction work in progress eligible for AFUDC equity.

Other expenses (income), net

Other expenses (income), net decreased for the year ended December 31, 2023 compared to the year ended December 31, 2022 due to an increase of $10 million in interest income. Additionally, net gains from certain investments associated with our supplemental benefit plans for the year ended December 31, 2023 compared to net losses for the year ended December 31, 2022 decreased other expenses (income), net by $9 million.

Liquidity and Capital Resources

We expect to maintain our approach of funding our future capital requirements with cash from operations at our Regulated Operating Subsidiaries, our existing cash and cash equivalents, future issuances under our commercial paper program and amounts available under our Revolving Credit Agreement (the terms of which are described in Note 9 to the consolidated financial statements). In addition, we may from time to time secure debt funding in the capital markets, although we can provide no assurance that we will be able to obtain financing on favorable terms or at all. As market conditions warrant, we may also from time to time repurchase debt securities issued by us in the open market, in privately negotiated transactions, by tender offer or otherwise. We expect that our capital requirements will arise principally from our need to:

•Fund capital expenditures (including purchase commitments as described in Note 17 to the consolidated financial statements) at our Regulated Operating Subsidiaries. Our plans with regard to property, plant and equipment investments are described in detail above under “— Capital Investment and Operating Results Trends.”

•Fund our debt service requirements, including principal repayments and periodic interest payments, which are further described below.

•Fund working capital requirements.

In addition to the expected capital requirements above, any adverse determinations or settlements relating to the regulatory matters or contingencies described in Notes 6 and 17 to the consolidated financial statements would result in additional capital requirements.

We believe that we have sufficient capital resources to meet our currently anticipated short-term (within twelve months) needs. However, we rely on both internal and external sources of liquidity to provide working capital and fund capital investments. An extended period of economic disruption could impact our ability to access the capital markets requiring us to seek alternative forms of financing which could negatively impact our liquidity and capital resources. ITC Holdings’ sources of cash are dividends and other payments received by us from our Regulated Operating Subsidiaries and any of our other subsidiaries as well as the proceeds raised from the sale of our debt securities. Each of our Regulated Operating Subsidiaries, while wholly-owned by ITC Holdings, is legally distinct from ITC Holdings and has no obligation, contingent or otherwise, to make funds available to us.

We expect to continue to utilize our commercial paper program and Revolving Credit Agreement as well as our cash and cash equivalents as needed to meet our short-term (within twelve months) cash requirements. As of December 31, 2023, we had consolidated indebtedness under our Revolving Credit Agreement of $311 million, with unused capacity under our Revolving Credit Agreement of $689 million. Additionally, ITC Holdings did not have any commercial paper issued and outstanding as of December 31, 2023, but has the ability to issue an aggregate amount not to exceed $400 million outstanding at any time under the commercial paper

34

program. In 2023, we paid $25 million of interest and commitment fees under our revolving credit agreements and commercial paper program. As of December 31, 2023, we had a balance of cash and cash equivalents of $328 million, compared to a balance of $4 million as of December 31, 2022. The increase in cash and cash equivalents was primarily a result of the June 1, 2023 issuance of $800 million of Senior Notes at ITC Holdings. We expect to utilize the unused net proceeds of cash and cash equivalents from this issuance to fund short-term (within twelve months) capital requirements. See Note 9 to the consolidated financial statements for a detailed discussion of the June 1, 2023 debt issuance at ITC Holdings, including the initial uses of net proceeds therefrom, the commercial paper program and our Revolving Credit Agreement.

To address our future capital requirements, we expect that we will need to obtain additional long-term debt financing. As of December 31, 2023, we had various notes and bonds outstanding with terms, including fixed interest rate and principal payment terms, specific to each borrowing. Maturity dates for these long-term debt issuances range from 2024 to 2055. Total future interest payment obligations associated with these existing fixed-rate, long-term debt obligations were $4.1 billion as of December 31, 2023, with expected interest payment obligations of $300 million due within the next twelve months. Certain of our capital projects could be delayed if we experience difficulties in accessing capital. We expect to be able to obtain such additional financing as needed, in amounts and upon terms that will be acceptable to us due to our strong credit ratings and our historical ability to obtain financing. Rising interest rates have resulted in higher coupon rates on recent long-term debt issuances and higher weighted average interest rates on commercial paper and borrowings under our revolving credit agreements. The increase in interest rates, combined with higher long-term debt balances due to additional issuances of long-term debt, has resulted in an increase to interest expense, net of $46 million for the year ended December 31, 2023, compared to the same period in 2022. There remains uncertainty surrounding expectations of future interest rate fluctuations.

METC has a contractual obligation through December 31, 2050 for an Easement Agreement for transmission purposes and rights-of-way, leasehold interests, fee interests and licenses associated with the land over which the transmission lines cross. The cost for use of the rights-of-way is $10 million per year. See Note 17 to the consolidated financial statements for additional details related to the easement.

We have certain obligations including contingent liabilities and other current and long-term liabilities, that have uncertainty regarding the timing and any amount of future cash flows necessary to settle these obligations. Such items include:

•long-term incentive awards;

•pension and other postretirement obligations;

•regulatory liabilities related to asset removal costs and refundable income taxes; and

•liabilities to refund deposits from generators for transmission network upgrades.

On April 14, 2023, we entered into the Revolving Credit Agreement, as described in Note 9 to the consolidated financial statements, that replaced the previous revolving credit agreements of ITC Holdings and certain of our Regulated Operating Subsidiaries. Under the Revolving Credit Agreement, the interest rate is based on a calculation that references either SOFR or a comparable benchmark as further outlined in the Revolving Credit Agreement and, as a result, we no longer have exposure to LIBOR that existed under the previous revolving credit agreements.

Credit Ratings

Credit ratings by nationally recognized statistical rating agencies are an important component of our liquidity profile. Credit ratings relate to our ability to issue debt securities and the cost to borrow money and should not be viewed as a recommendation to buy, sell or hold securities. Ratings are subject to revision or withdrawal at any time and each rating should be evaluated independently of any other rating. Our current credit ratings are

35

displayed in the following table. An explanation of these ratings may be obtained from the respective rating agency.

	S&P Global Ratings		Moody’s Investor Service, Inc.
	Rating	Outlook (a)	Rating	Outlook
ITC Holdings
Senior Unsecured Notes	BBB+	Negative	Baa2	Stable

____________________________

(a)On November 3, 2023, S&P Global Ratings reaffirmed the ratings on ITC Holdings and certain of our Regulated Operating Subsidiaries and revised all outlooks from stable to negative.

Covenants

Our debt instruments contain numerous financial and operating covenants that place significant restrictions on certain transactions, such as incurring additional indebtedness, engaging in sale and lease-back transactions, creating liens or other encumbrances, entering into mergers, consolidations, liquidations or dissolutions, creating or acquiring subsidiaries and selling or otherwise disposing of all or substantially all of our assets. In addition, the covenants require us to meet certain financial ratios, such as maintaining certain debt to capitalization ratios and certain funds from operations to debt levels. As of December 31, 2023, we were not in violation of any debt covenant. In the event of a downgrade in our credit ratings, none of the covenants would be directly impacted, although the borrowing costs under our Revolving Credit Agreement may increase.

Cash Flows

The following table summarizes cash flows for the periods indicated:

	Year Ended						Percentage
	December 31,				Increase		increase
(In millions of USD)	2023		2022		(decrease)		(decrease)
Cash Flows provided by (used in):
Operating activities	$	849	$	892	$	(43)	(5)	%
Investing activities	(836)		(925)		(89)		(10)	%
Financing activities	314		32		282		881	%
Net increase (decrease) in cash, cash equivalents and restricted cash	$	327	$	(1)

Cash Flows From Operating Activities

Net cash provided by operating activities decreased primarily due to an increase in interest paid of $49 million, an increase in income taxes paid of $38 million, a decrease in cash received for settlement of interest rate swaps of $35 million and an increase in property tax payments of $7 million during the year ended December 31, 2023 compared to the year ended December 31, 2022. This decrease was partially offset by an increase in cash received from operating revenues of $77 million and a decrease in payments pursuant to our long-term incentive plans of $12 million during the year ended December 31, 2023 compared to the year ended December 31, 2022.

36

Cash Flows From Investing Activities

Net cash used in investing activities decreased primarily due to a decrease in capital expenditures of $115 million partially offset by an increase in net refund payments of contributions in aid of construction of $23 million during the year ended December 31, 2023 compared to the year ended December 31, 2022.

Cash Flows From Financing Activities

Net cash provided by financing activities increased primarily due to a decrease in repayments of long-term debt of $250 million, an increase in net borrowings under our revolving credit agreements of $224 million and an increase in net refundable deposits for transmission network upgrades of $17 million during the year ended December 31, 2023 compared to the year ended December 31, 2022. This increase was partially offset by an increase in net repayments of commercial paper of $113 million, a decrease in issuances of long-term debt of $86 million and an increase in dividend payments of $10 million during the year ended December 31, 2023 compared to the year ended December 31, 2022. See Note 9 to the consolidated financial statements for additional discussion on debt.

Critical Accounting Estimates

Our consolidated financial statements are prepared in accordance with GAAP. The preparation of these consolidated financial statements requires the application of appropriate technical accounting rules and guidance, as well as the use of estimates. The application of these policies requires judgments regarding future events.

These estimates and judgments, in and of themselves, could materially impact the consolidated financial statements and disclosures based on varying assumptions, as future events rarely develop exactly as forecasted, and even the best estimates routinely require adjustment.

The following accounting policies are the most significant to the portrayal of our financial condition and results of operations and/or that require management’s most difficult, subjective or complex judgments.

Regulation

Our Regulated Operating Subsidiaries are subject to rate regulation by the FERC. As a result, we apply accounting principles in accordance with the standards set forth by the FASB for accounting for the effects of certain types of regulation. Use of this accounting guidance results in differences in the application of GAAP between regulated and non-regulated businesses and requires the recording of regulatory assets and liabilities for certain transactions that would have been treated as expense or revenue in non-regulated businesses. As described in Note 7 to the consolidated financial statements, we had regulatory assets and liabilities of $205 million and $762 million, respectively, as of December 31, 2023. Future changes in the regulatory and competitive environments could result in discontinuing the application of the accounting standards for the effects of certain types of regulations. If we were to discontinue the application of this guidance on the operations of our Regulated Operating Subsidiaries, we may be required to record losses relating to certain regulatory assets or gains relating to certain regulatory liabilities. We also may be required to record losses of $19 million relating to intangible assets at December 31, 2023 that are included in other assets on the consolidated statements of financial position.

We believe that currently available facts support the continued applicability of the standards for accounting for the effects of certain types of regulation and that all regulatory assets and liabilities are recoverable or refundable under our current rate environment.

Revenue Recognition under Cost-Based Formula Rates with True-Up Mechanism

Our Regulated Operating Subsidiaries recover expenses and earn an authorized return on and recover investments in property, plant and equipment on a current basis, under their forward-looking cost-based Formula Rates with a true-up mechanism.

Under their Formula Rates, our Regulated Operating Subsidiaries use forecasted expenses, property, plant and equipment, point-to-point revenues and other items for the upcoming calendar year to establish their projected revenue requirement and for the MISO Regulated Operating Subsidiaries, their component of the billed network rates for service on their systems from January 1 to December 31 of that year. Our Formula Rates include a true-up mechanism, whereby our Regulated Operating Subsidiaries compare their actual

37

revenue requirements to their billed revenues for each year to determine any over- or under-collection of revenue. The over- or under-collection typically results from differences between the projected revenue requirement used as the basis for billing and actual revenue requirement at each of our Regulated Operating Subsidiaries, or from differences between actual and projected monthly network peak loads at our MISO Regulated Operating Subsidiaries.

The true-up mechanisms under our Formula Rates meet the GAAP requirements for accounting for rate-regulated utilities and the effects of certain alternative revenue programs. Accordingly, revenue is recognized during each reporting period based on actual revenue requirements calculated using the cost-based Formula Rates. Our Regulated Operating Subsidiaries accrue or defer revenues to the extent that their actual revenue requirement for the reporting period is higher or lower, respectively, than the amounts billed relating to that reporting period. The true-up amount is automatically reflected in customer bills within two years under the provisions of the Formula Rates. See Note 7 to the consolidated financial statements for the regulatory assets and liabilities recorded at our Regulated Operating Subsidiaries’ as a result of the Formula Rate revenue accruals and deferrals.

Contingent Obligations

See Note 3 to the consolidated financial statements for a description of the policy for estimating contingent obligations. The adequacy of liabilities recorded for contingent obligations can be significantly affected by external events or conditions that can be unpredictable; thus, the ultimate outcome of such matters could materially affect our consolidated financial statements. These events or conditions include, without limitation, the following:

•Changes in existing state or federal regulation by governmental authorities having jurisdiction over air quality, water quality, control of toxic substances, hazardous and solid wastes and other environmental matters;

•Changes in existing federal income tax laws or IRS regulations;

•Identification and evaluation of lawsuits or complaints in which we may be or have been named as a defendant; and

•Resolution or progression of existing matters through the legislative process, the courts, the FERC, the NERC, the IRS or the Environmental Protection Agency.

Pension and Postretirement Benefit Plan Assumptions

We sponsor certain retirement benefits for our employees, which include retirement pension plans and certain postretirement health care, dental and life insurance benefits. Our periodic costs and obligations associated with these plans are developed from actuarial valuations derived from a number of assumptions. Key assumptions include:

•Discount rates used to determine obligations - Benefit obligations, service cost and interest cost are determined by separately discounting projected benefit payments using a yield curve of high-quality corporate bonds. As of December 31, 2023, the weighted average single equivalent discount rate for the benefit obligation was 5.19% and 5.30% for our pension and postretirement benefit plans, respectively.

•Expected long-term returns on plan assets - In determining our long-term rate of return on plan assets, we consider the current and expected asset allocations, as well as historical and expected long-term rates of return on those types of asset classes. For the year ended December 31, 2023, we assumed that our pension and postretirement benefit plans’ assets would generate weighted average long-term rates of return of 6.90% and 5.20%, respectively.

•Rate of salary increases - As of December 31, 2023, we used an annual rate of salary increases of 4.50% to determine our pension and postretirement plan obligations.

•Mortality - The Pri-2012 mortality table projected forward generationally from 2012 with the MP-2020 mortality improvement scale was used to determine pension and postretirement plan obligations as of December 31, 2023.

38

•Rate of increase in health care costs - We used a health care cost trend rate of 6.50% for 2024 grading down to a 5.00% ultimate rate in 2030 in valuing our postretirement benefit obligation as of December 31, 2023. These rates are based on a review of recent and expected future experience.

The below table displays the effect on our costs and obligation of a 1% change to certain pension and postretirement benefit plan assumptions as of December 31, 2023:

	Effect on Costs				Effect on Obligation
(in millions of USD)	1% Increase		1% Decrease		1% Increase		1% Decrease
Change to Pension Plans
Discount rate	$	—	$	—	$	(13)	$	16
Long-term rate of return on plan assets	(1)		1		N/A		N/A
Change to Postretirement Plan
Discount rate	(3)		3		(14)		17
Long-term rate of return on plan assets	(1)		1		N/A		N/A
Health care cost trend rate	4		(3)		15		(12)

See Note 11 to the consolidated financial statements for further details regarding our pension and postretirement benefit plan costs and obligations.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably likely to have a material effect on our financial condition.

Recent Accounting Pronouncements

See Note 2 to the consolidated financial statements.

ITEM 7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Commodity Price Risk

We have commodity price risk at our Regulated Operating Subsidiaries arising from market price fluctuations for materials such as copper, aluminum, steel, oil and gas and other goods used in construction and maintenance activities. Higher costs of these materials are passed on to us by the contractors for these activities. These items affect only cash flows, as the amounts are included as components of net revenue requirement and any higher costs are included in rates under their cost-based Formula Rates.

Interest Rate Risk

Fixed Rate Debt

Based on the borrowing rates currently available for bank loans with similar terms and average maturities, the fair value of our consolidated long-term debt and debt maturing within one year, excluding revolving credit agreements and commercial paper, was $6,660 million and $5,849 million at December 31, 2023 and 2022, respectively. The total book value of our consolidated long-term debt and debt maturing within one year, net of discount and deferred financing fees and excluding revolving credit agreements and commercial paper, was $7,287 million and $6,649 million at December 31, 2023 and 2022, respectively. An increase in interest rates of 10% (from 5.0% to 5.5%, for example) at December 31, 2023 and 2022 would decrease the fair value of debt by $278 million and $270 million, respectively, and a decrease in interest rates of 10% at December 31, 2023 and 2022 would increase the fair value of debt by $303 million and $297 million, respectively, at that date.

Revolving Credit Agreements

At December 31, 2023 and 2022, we had a consolidated total of $311 million and $208 million, respectively, outstanding under our revolving credit agreements, which are variable rate loans and fair value approximates book value. A 10% increase or decrease in borrowing rates under the revolving credit agreements compared to the weighted average rates in effect at December 31, 2023 and 2022 would increase or decrease annual interest expense by $2 million and $1 million, respectively, at borrowing levels consistent with amounts outstanding at the end of each of the respective periods.

39

Commercial Paper

At December 31, 2023, ITC Holdings did not have any commercial paper issued and outstanding under the commercial paper program. At December 31, 2022, ITC Holdings had $134 million of commercial paper issued and outstanding, net of discount, under the commercial paper program. Due to the short-term nature of these financial instruments, the carrying value approximates fair value. A 10% increase or decrease in interest rates for commercial paper compared to the weighted average interest rates in effect at December 31, 2022 would increase or decrease annual interest expense by $1 million at levels consistent with amounts issued and outstanding at the end of such period.

Derivative Instruments and Hedging Activities

We use derivative financial instruments, including interest rate swap contracts and U.S. Treasury rate lock contracts, to manage our exposure to fluctuations in interest rates. The use of these financial instruments mitigates exposure to these risks and the variability of our operating results. We are not a party to leveraged derivatives and do not enter into derivative financial instruments for trading or speculative purposes.

During 2023, we terminated $500 million of 10-year U.S. Treasury rate lock contracts that managed interest rate risk associated with the ITC Holdings 5.40% Senior Notes, due June 1, 2033. During 2022, we terminated $450 million of 5-year interest rate swap contracts that managed interest rate risk associated with the ITC Holdings 4.95% Senior Notes, due September 22, 2027. Refer to Note 9 to the consolidated financial statements for additional information. At December 31, 2023 and 2022, ITC Holdings did not have any derivative financial instruments outstanding to manage exposure to fluctuations in interest rates.

Credit Risk

Our credit risk is primarily with DTE Electric, Consumers Energy and IP&L, which were responsible for approximately 21.7%, 21.3% and 24.5%, respectively, or $338 million, $332 million and $382 million, respectively, of our consolidated billed revenues for the year ended December 31, 2023. This portion of total billed revenues of DTE Electric, Consumers Energy and IP&L include the refund of 2021 revenue accruals and deferrals and exclude any amounts for the 2023 revenue accruals and deferrals that were included in our 2023 operating revenues but will not be billed to our customers until 2025.

For the year ended December 31, 2022, our credit risk was primarily with DTE Electric, Consumers Energy and IP&L, which were responsible for approximately 21.0%, 24.0% and 25.4%, respectively, or $310 million, $354 million and $375 million, respectively, of our consolidated billed revenues. These percentages and amounts of total billed revenues of DTE Electric, Consumers Energy and IP&L include the collection of 2020 revenue accruals and deferrals and exclude any amounts for the 2022 revenue accruals and deferrals that were included in our 2022 operating revenues but will not be billed to our customers until 2024.

Refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Cost-Based Formula Rates with True-Up Mechanism” for a discussion on the difference between billed revenues and operating revenues. Under DTE Electric’s and Consumers Energy’s current rate structure, DTE Electric and Consumers Energy include in their retail rates the actual cost of transmission services provided by ITCTransmission and METC, respectively, in their billings to their customers, effectively passing through to end-use consumers the total cost of transmission service. IP&L currently includes in their retail rates an allowance for transmission services provided by ITC Midwest in their billings to their customers. However, any financial difficulties experienced by DTE Electric, Consumers Energy or IP&L may affect their ability to make payments for transmission service to ITCTransmission, METC, and ITC Midwest, which could negatively impact our business. MISO, as our MISO Regulated Operating Subsidiaries’ billing agent, bills DTE Electric, Consumers Energy, IP&L and other customers on a monthly basis and collects fees for the use of the MISO Regulated Operating Subsidiaries’ transmission systems. SPP is the billing agent for ITC Great Plains and bills transmission customers for the use of ITC Great Plains transmission systems. MISO and SPP have implemented strict credit policies for its members’ customers, which include customers using our transmission systems. Specifically, MISO and SPP require a letter of credit or cash deposit equal to the credit exposure, which is determined by a credit scoring model and other factors, from any customer using a member’s transmission system.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is designed to provide reasonable, not absolute, assurance as to the reliability of our financial reporting and the preparation of consolidated financial statements in accordance with generally accepted accounting principles. Internal control over financial reporting, no matter how well designed, has inherent limitations. Therefore, internal control over financial reporting determined to be effective can provide only reasonable assurance with respect to financial statement preparation and may not prevent or detect all misstatements.

Under management’s supervision, an evaluation of the design and effectiveness of our internal control over financial reporting was conducted based on the criteria set forth in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our assessment included documenting, evaluating and testing of the design and operating effectiveness of our internal control over financial reporting. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2023.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholder of

ITC Holdings Corp.

Novi, Michigan

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of ITC Holdings Corp. and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of comprehensive income, stockholder’s equity, and cash flows for each of the three years in the period ended December 31, 2023, and the related notes and the schedule listed in the Index at Item 15 (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, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, 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 and in accordance with auditing standards generally accepted in the United States of America. 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 and Risk 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.

Regulatory Matters — Impact of rate regulation on the financial statements – Refer to Notes 3, 6, 7, and 17 to the financial statements

Critical Audit Matter Description

The Company’s Regulated Operating Subsidiaries are subject to rate regulation by the Federal Energy Regulatory Commission (the “regulatory agency”). Management has determined it meets the requirements under accounting principles generally accepted in the United States of America to prepare its financial

43

statements applying the specialized rules to account for the effects of cost-based rate regulation. The cost-based Formula Rates at the Company’s Regulated Operating Subsidiaries recover expenses and earn an authorized return on and recover investments in property, plant and equipment on a current basis and include a true-up mechanism. Regulatory decisions and legal challenges can have an impact on rates, recovery of certain costs, including the costs of transmission assets and regulatory assets, conditions of service, accounting, financing authorization, operating-related matters, timing of actual collection, and the return on equity. Accounting for the economics of rate regulation impacts certain financial statement line items and disclosures.

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 certain impacted account balances and disclosures and the high degree of subjectivity involved in assessing the potential impact of future regulatory orders on the financial statements. Management judgments include assessing the likelihood of recovery of costs incurred or potential refunds to customers. While the Company has indicated they expect to recover costs from customers through regulated rates, there is a risk that the formula inputs, including the return on equity, remain subject to legal challenge at the regulatory agency. The Company uses the formula to calculate annual revenue requirements unless the regulatory agency determines the resulting rates to be unjust and unreasonable. Auditing these judgments required especially subjective judgment and specialized knowledge of accounting for rate regulation and the rate-setting process due to their inherent complexities.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the impact of rate regulation and the uncertainty of future decisions by the regulatory agency included the following, among others:

•We tested the effectiveness of controls over the monitoring and evaluation of contingent liabilities and regulatory developments that may affect the likelihood of recovering costs in future rates or of a future reduction in rates.

•We assessed relevant regulatory orders and interpretations, as well as, utility and intervener filings, legal decisions, and other publicly available information to evaluate the likelihood of recovery in future rates or of future reduction in rates and the ability to earn a reasonable return on equity.

•For regulatory matters in process, we inspected the annual formula rate filings and open complaints for any evidence that might contradict management’s assertions. We obtained and evaluated an analysis from management, regarding cost recoveries or potential future reduction in rates.

•We obtained letters from the Company’s internal and external legal counsel to assess management’s conclusions and disclosures.

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

ITC HOLDINGS CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    GENERAL

ITC Holdings and its subsidiaries are engaged in the transmission of electricity in the United States. ITC Holdings is a wholly-owned subsidiary of ITC Investment Holdings. Fortis owns a majority indirect equity interest in ITC Investment Holdings, with GIC holding an indirect, passive, non-voting equity interest of 19.9%. Through our Regulated Operating Subsidiaries, we own, operate, maintain and invest in high-voltage transmission systems in Michigan’s Lower Peninsula and portions of Iowa, Minnesota, Illinois, Missouri, Kansas, Oklahoma and Wisconsin that transmit electricity from generating stations to local distribution facilities connected to our transmission systems.

Our Regulated Operating Subsidiaries are independent electric transmission utilities, with cost-based rates regulated by the FERC. ITCTransmission’s service area is located in southeastern Michigan, while METC’s service area covers approximately two-thirds of Michigan’s Lower Peninsula and is contiguous with ITCTransmission’s service area. ITC Midwest’s service area is located in portions of Iowa, Minnesota, Illinois, Missouri and Wisconsin. ITC Great Plains currently owns assets located in Kansas and Oklahoma.

2.    RECENT ACCOUNTING PRONOUNCEMENTS

Recently Issued Pronouncements

Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued authoritative guidance to improve reportable segment disclosure requirements, thereby enabling investors to better understand an entity’s performance and assess potential future cash flows. The new guidance requires that public entities disclose, on an annual and interim basis, additional information related to significant segment expenses regularly provided to the chief operating decision maker and other segment items. The guidance also contains several other provisions, notably requiring disclosure in interim periods of all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280 of the FASB’s Accounting Standards Codification. The guidance is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are evaluating the impact of the new guidance on our disclosures.

Enhancements to Income Tax Disclosures

In December 2023, the FASB issued authoritative guidance modifying the disclosure requirements for income tax. This update is intended to provide investors information to better assess how an entity’s operations and related tax risks, tax planning and operational opportunities affect its tax rate and prospects for future cash flows. Notable changes in the new guidance include disaggregation of income tax information by jurisdiction and changes to the presentation of information for the reconciliation of effective tax rates. The guidance is effective for fiscal years beginning after December 15, 2024 with early adoption permitted. We are evaluating the impact of the new guidance on our disclosures.

3.    SIGNIFICANT ACCOUNTING POLICIES

A summary of the major accounting policies followed in the preparation of the accompanying consolidated financial statements, which conform to GAAP, is presented below:

Principles of Consolidation — ITC Holdings consolidates its majority owned subsidiaries. We eliminate all intercompany balances and transactions.

Use of Estimates — The preparation of the consolidated financial statements requires us to use estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results may differ from our estimates.

Regulation — Our Regulated Operating Subsidiaries are subject to the regulatory jurisdiction of the FERC, which issues orders pertaining to rates, recovery of certain costs, including the costs of

49

transmission assets and regulatory assets, conditions of service, accounting, financing authorization and operating-related matters. The utility operations of our Regulated Operating Subsidiaries meet the accounting standards set forth by the FASB for the accounting effects of certain types of regulation. These accounting standards recognize the cost-based rate setting process, which results in differences in the application of GAAP between regulated and non-regulated businesses. These standards require the recording of regulatory assets and liabilities for certain transactions that would have been recorded in the statements of comprehensive income in non-regulated businesses. Regulatory assets represent costs that will be included as a component of future tariff rates and regulatory liabilities represent amounts provided in the current tariff rates that are intended to recover costs expected to be incurred in the future or amounts to be refunded to customers.

Cash and Cash Equivalents — We consider all unrestricted highly-liquid temporary investments with an original maturity of three months or less at the date of purchase to be cash equivalents.

Restricted Cash — Restricted cash includes cash that is legally or contractually restricted for use or withdrawal or are formally set aside for a specific purpose. Restricted cash primarily represents cash on deposit to pay for vegetation management, land easements and land purchases for the purpose of transmission line construction as well as amounts liquidated to make benefit payments related to our supplemental benefit plans.

Inventories — Materials and supplies inventories are valued at average cost. Additionally, the costs of warehousing activities are recorded here and included in the cost of materials when requisitioned.

Property, Plant and Equipment — Depreciation and amortization expense on property, plant and equipment was $300 million, $286 million and $223 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Property, plant and equipment in service at our Regulated Operating Subsidiaries is stated at its original cost when first devoted to utility service. The gross book value of assets retired less salvage proceeds is charged to accumulated depreciation. The provision for depreciation of transmission assets is a significant component of our Regulated Operating Subsidiaries’ cost of service under FERC-approved rates. Periodically, we perform depreciation studies of the assets at our Regulated Operating Subsidiaries. The results of these studies are submitted to and require approval from the FERC prior to changing our depreciation rates. Depreciation is computed over the estimated useful lives of the assets using the straight-line method for financial reporting purposes and accelerated methods for income tax reporting purposes. The composite depreciation rate for our Regulated Operating Subsidiaries included in our consolidated statements of comprehensive income was 2.4% for each of the years ended December 31, 2023 and 2022 and 2.0% for the year ended December 31, 2021. The composite depreciation rates include depreciation primarily on transmission station equipment, towers, poles and overhead and underground lines that have a useful life ranging from 43 to 70 years. The portion of depreciation expense related to asset removal costs is added to regulatory liabilities or deducted from regulatory assets and removal costs incurred are deducted from regulatory liabilities or added to regulatory assets. Certain of our Regulated Operating Subsidiaries capitalize to property, plant and equipment AFUDC in accordance with FERC regulations. AFUDC represents the composite cost incurred to fund the construction of assets, including interest expense and a return on equity capital devoted to construction of assets. The interest component of AFUDC was a reduction to interest expense of $11 million, $9 million and $8 million for the years ended December 31, 2023, 2022 and 2021, respectively.

For acquisitions of property, plant and equipment greater than the net book value (other than asset acquisitions accounted for under the purchase method of accounting that result in goodwill), the acquisition premium is recorded to property, plant and equipment and amortized over the estimated remaining useful lives of the assets using the straight-line method for financial reporting purposes and accelerated methods for income tax reporting purposes.

Property, plant and equipment includes capital equipment stated at original cost consisting of items that are expected to be used exclusively for capital projects.

Property, plant and equipment at our non-regulated subsidiaries is stated at its acquired cost. Proceeds from salvage less the net book value of the disposed assets is recognized as a gain or loss on disposal. Depreciation is computed based on the acquired cost less expected residual value and is

50

recognized over the estimated useful lives of the assets on a straight-line method for financial reporting purposes and accelerated methods for income tax reporting purposes.

Generator Interconnection Projects and Contributions in Aid of Construction — Certain capital investment at our Regulated Operating Subsidiaries relates to investments made under GIAs. The GIAs typically consist of both transmission network upgrades, which are a category of upgrades deemed by the FERC to benefit the transmission system as a whole, as well as direct connection facilities, which are necessary to interconnect the generating facility to the transmission system and primarily benefit the generating facility. GIAs typically require the generator to make a contribution in aid of construction to our Regulated Operating Subsidiaries to cover the cost of certain investments made by us as part of the agreement. However, we may fund construction of certain projects without contributions from the generators.

Our investments in transmission facilities are recorded to property, plant and equipment, and are recorded net of any contribution in aid of construction. We also receive refundable deposits from the generator for certain investment in network upgrade facilities in advance of construction, which are recorded to current or non-current liabilities depending on the expected refund date.

Jointly Owned Utility Plant/Coordinated Services — Certain of our Regulated Operating Subsidiaries have agreements with other utilities for the joint ownership of assets as described in Note 15. We account for these jointly owned assets by recording property, plant and equipment for the percentage of our undivided ownership interest. Various agreements provide the authority for construction of capital improvements and the operating costs associated with the substations and lines. Generally, each party is responsible for the capital, operation and maintenance, and other costs of these jointly owned facilities based upon each participant’s undivided ownership interest, and each participant is responsible for providing its own financing. Our participating share of expenses associated with these jointly held assets is primarily recorded within operation and maintenance expense on our consolidated statements of comprehensive income.

Fair Value Through Net Income — We have certain investments in mutual funds, including fixed income securities and equity securities, that are classified as fair value through net income. The investments fund our two supplemental nonqualified, noncontributory retirement benefit plans for selected management employees as described in Note 11, as well as other deferred compensation plans. Gains and losses associated with these investments are recorded in other expenses (income), net in the consolidated statements of comprehensive income.

Impairment of Long-Lived Assets — Other than goodwill, our long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If the carrying amount of the asset exceeds the expected undiscounted future cash flows generated by the asset, the asset is written down to its estimated fair value and an impairment loss is recognized in our consolidated statements of comprehensive income.

Goodwill — Goodwill is not subject to amortization; however, goodwill is required to be assessed for impairment, and a resulting write-down, if any, is to be reflected in operating expense. We have goodwill recorded relating to our acquisitions of ITCTransmission and METC, and ITC Midwest’s acquisition of the IP&L transmission assets. Goodwill is reviewed at the reporting unit level at least annually for impairment and whenever facts or circumstances indicate that the value of goodwill may be impaired. Our reporting units are ITCTransmission, METC and ITC Midwest as each entity represents an individual operating segment to which goodwill has been assigned. At December 31, 2023 and 2022, we had goodwill balances recorded at ITCTransmission, METC and ITC Midwest of $173 million, $454 million and $323 million, respectively.

In order to perform an impairment analysis, we have the option of performing a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, in which case no further testing is required. If an entity bypasses the qualitative assessment or performs a qualitative assessment but determines that it is more likely than not that a reporting unit’s fair value is less than its carrying amount, a quantitative, fair value-based test is performed to assess and measure goodwill impairment, if any. If a quantitative assessment is performed, we determine the fair value of our reporting

51

units using valuation techniques based on discounted future cash flows under various scenarios and consider estimates of market-based valuation multiples for companies within the peer group of our reporting units.

We completed our annual goodwill impairment test for our reporting units as of October 1, 2023 and determined that no impairment exists. There were no events subsequent to October 1, 2023 that indicated impairment of our goodwill.

Deferred Financing Fees and Discount or Premium on Debt — Costs related to the issuance of long-term debt are generally recorded as a direct deduction from the carrying amount of the related debt and amortized over the life of the debt. Debt issuance costs incurred prior to the associated debt funding are presented as an asset. Unamortized debt issuance costs associated with the revolving credit agreements, commercial paper and other similar arrangements are presented as an asset (regardless of whether there are any amounts outstanding under those credit facilities) and amortized over the life of the particular arrangement. The debt discount or premium related to the issuance of long-term debt is recorded to long-term debt and amortized over the life of the debt. We recorded $6 million for each of the years ended December 31, 2023 and 2022 and $5 million for the year ended December 31, 2021 to interest expense for the amortization of deferred financing fees and debt discounts.

Asset Retirement Obligations — A conditional asset retirement obligation is a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within our control. We have identified conditional asset retirement obligations primarily associated with the removal of equipment containing PCBs and asbestos. We record a liability at fair value for a legal asset retirement obligation in the period in which it is incurred. When a new legal obligation is recorded, we capitalize the costs of the liability by increasing the carrying amount of the related long-lived asset. We accrete the liability to its present value each period and depreciate the capitalized cost over the useful life of the related asset. At the end of the asset’s useful life, we settle the obligation for its recorded amount. We recognize regulatory assets for the timing differences between the incurred costs to settle our legal asset retirement obligations and the recognition of such obligations as applicable for our Regulated Operating Subsidiaries. Our asset retirement obligations of $5 million as of December 31, 2023 and 2022 are included in other liabilities.

Derivatives and Hedging — We may use derivative financial instruments to manage our exposure to fluctuations in interest rates. For derivative instruments that have been designated and qualify as cash flow hedges of the exposure to variability in expected future cash flows, the unrealized gain or loss on the derivative is initially reported, net of tax, as a component of other comprehensive income (loss) and reclassified to the consolidated statements of comprehensive income when the underlying hedged transaction affects net income. Cash flows related to derivative instruments that are designated in hedging relationships are generally classified on the consolidated statements of cash flows within cash flows from operating activities. The fair values of derivatives are recognized as current or long-term assets and liabilities depending on the timing of settlements and resulting cash flows. Refer to Note 9 for additional discussion regarding derivative instruments.

Contingent Obligations — We are subject to a number of federal and state laws and regulations, as well as other factors and conditions that potentially subject us to environmental, litigation, income tax and other contingencies. We periodically evaluate our exposure to such contingencies and record liabilities for those matters where a loss is considered probable and reasonably estimable. We reverse the liabilities recorded for those matters when a loss is no longer considered probable or the liabilities are otherwise settled. Our liabilities exclude any estimates for legal costs not yet incurred associated with handling these matters, which could be material. The adequacy of liabilities recorded can be significantly affected by external events or conditions that can be unpredictable; thus, the ultimate outcome of such matters could materially affect our consolidated financial statements.

Revenues — Substantially all of our revenue from contracts with customers is generated from providing transmission services to customers as services are provided based on our FERC-approved cost-based Formula Rates. We record a reserve for revenue subject to refund when such refund is probable and can be reasonably estimated. This reserve is recorded as a reduction to operating revenues.

52

The cost-based Formula Rates at our Regulated Operating Subsidiaries include a true-up mechanism that compares the actual revenue requirements of our Regulated Operating Subsidiaries to their billed revenues for each year to determine any over- or under-collection of revenue requirements and we record a revenue deferral or accrual for the difference. The true-up mechanisms under our Formula Rates are considered alternative revenue programs of rate-regulated utilities. Operating revenues arising from these alternative revenue programs are presented on our consolidated statements of comprehensive income in the line “Formula Rate true-up”, which is separate from the reporting of our tariff revenues, which are presented in the line “Transmission and other services.” Only the initial origination of our alternative revenue program revenue is reported in the Formula Rate true-up line on our consolidated statements of comprehensive income. When those amounts are subsequently included in the price of utility service and billed or refunded to customers, we account for that event as the recovery or settlement of the associated regulatory asset or regulatory liability, respectively. Refer to Note 6 under “Cost-Based Formula Rates with True-Up Mechanism” and Note 4 under “Formula Rate True-Up” for a discussion of our revenue accounting under our cost-based Formula Rates.

Share-Based Payment — Under long-term incentive plans, we grant long-term incentive awards consisting of PBUs and SBUs to employees, including executive officers, of ITC Holdings. Generally, each PBU and SBU granted is valued based on one share of Fortis common stock traded on the Toronto Stock Exchange, converted to U.S. dollars and settled only in cash. However, certain SBUs granted to the executives may settle in cash, 100% Fortis common stock, or 50% cash and 50% Fortis common stock depending on executives’ settlement elections and whether certain share ownership requirements are met. All PBUs and SBUs are classified as liability awards and generally vest on the third January 1st following the grant date, provided the service and performance criteria, as applicable, are satisfied, and will be settled during the subsequent quarter. However, certain awards may vest over a shorter period or on the grant date if certain retirement eligibility criteria are met. The PBUs and SBUs earn dividend equivalents, which are also re-measured and settled consistent with the target award at the end of the vesting period. The granted awards and related dividend equivalents have no shareholder rights.

Compensation cost is recognized over the expected vesting period and remeasured each reporting period based on Fortis’ stock price. The PBUs are also remeasured each reporting period based on the applicable market and performance conditions in the awards. Compensation cost is adjusted for forfeitures in the period in which they occur and the final measure of compensation cost for the awards is based on the cash settlement amount.

Refer to Note 14 for additional discussion of the plans.

Comprehensive Income (Loss) — Comprehensive income (loss) is the change in stockholder’s equity during a period arising from transactions and events from non-owner sources, including net income and any gain or loss arising from derivative financial instruments.

Income Taxes — Deferred income taxes are recognized for the expected future tax consequences of events that have been recognized in the consolidated financial statements or tax returns. Deferred income tax assets and liabilities are determined based on the differences between the financial statements and the tax bases of various assets and liabilities, using the tax rates expected to be in effect for the year in which the differences are expected to reverse, and classified as non-current in our consolidated statements of financial position.

The accounting standards for uncertainty in income taxes prescribe a recognition threshold and a measurement attribute for tax positions taken, or expected to be taken, in a tax return that may not be sustainable. As of December 31, 2023, we have not recognized any uncertain income tax positions.

We file our federal and Michigan income tax returns as part of the FortisUS consolidated tax returns and we are a party to an intercompany tax sharing agreement that establishes the method for determining tax liabilities that are due and allocating tax attributes that are utilized on the consolidated income tax returns. We continue to file with various other state and city jurisdictions where we have a separate return filing obligation. Our prior consolidated federal tax returns are no longer subject to U.S. federal tax examinations for tax years 2019 and earlier. State and city jurisdictions that remain subject to examination range from tax years 2019 to 2022. In the event we are assessed interest or penalties by any income tax jurisdictions, interest and penalties would be recorded as interest expense and other expenses,

53

respectively, in our consolidated statements of comprehensive income. Refer to Note 10 for additional discussion on income taxes.

4.    REVENUE

Our total revenues are comprised of revenues which arise from three classifications including transmission services, other services and Formula Rate true-up. As other services revenue is immaterial, it is presented in combination with transmission services on the consolidated statements of comprehensive income.

Transmission Services

Through our Regulated Operating Subsidiaries, we generate nearly all our revenue from providing electric transmission services over our transmission systems. As independent transmission companies, our transmission services are provided and revenues are received based on our tariffs, as approved by the FERC. We recognize revenue for transmission services over time as transmission services are provided to customers (generally using an output measure of progress based on transmission load delivered). Customers simultaneously receive and consume the benefits provided by the Regulated Operating Subsidiaries’ services. We recognize revenue in the amount to which we have the right to invoice because we have a right to consideration in an amount that corresponds directly with the value to the customer of performance completed to date. As billing agents, MISO and SPP independently bill our customers on a monthly basis and collect fees for the use of our transmission systems. No component of the transaction price is allocated to unsatisfied performance obligations.

Transmission service revenue includes an estimate for unbilled revenues from service that has been provided but not billed by the end of an accounting period. Unbilled revenues are dependent upon a number of factors that require management’s judgment including estimates of transmission network load (for the MISO Regulated Operating Subsidiaries) and preliminary information provided by billing agents. Due to the seasonal fluctuations of actual load, the unbilled revenue amount generally increases during the spring and summer and decreases during the fall and winter. See Note 5 for information on changes in unbilled accounts receivable.

Other Services

Other services revenue consists of rental revenues, easement revenues and amounts from providing ancillary services. A portion of other services revenue is treated as a revenue credit and reduces gross revenue requirement when calculating net revenue requirement under our Formula Rates. Total other services revenue was $6 million for each of the years ended December 31, 2023, 2022 and 2021.

Formula Rate True-Up

The true-up mechanism under our Formula Rates is considered an alternative revenue program of a rate-regulated utility given it permits our Regulated Operating Subsidiaries to adjust future rates in response to past activities or completed events in order to collect our actual revenue requirements under our Formula Rates. In accordance with our accounting policy, only the current year origination of the true-up is reported as a Formula Rate true-up. See “Cost-Based Formula Rates with True-Up Mechanism” in Note 6 for more information on our Formula Rates.

6.    REGULATORY MATTERS

Cost-Based Formula Rates with True-Up Mechanism

The transmission revenue requirements at our Regulated Operating Subsidiaries are set annually using Formula Rates and remain in effect for a one-year period. By updating the inputs to the formula and resulting rates on an annual basis, the revenues at our Regulated Operating Subsidiaries reflect changing operational data and financial performance, including the amount of network load on their transmission systems (for our MISO Regulated Operating Subsidiaries), operating expenses and additions to property, plant and equipment when placed in service, among other items. The formula used to derive the rates does not require further action or FERC filings each year, although the formula inputs remain subject to legal challenge at the FERC. Our Regulated Operating Subsidiaries will continue to use the formula to calculate their respective annual revenue requirements unless the FERC determines the resulting rates to be unjust and unreasonable and another mechanism is determined by the FERC to be just and reasonable. See “Rate of Return on Equity Complaints” in Note 17 for detail on ROE matters for our MISO Regulated Operating Subsidiaries and "ROE and Incentive Adders for Transmission Rates" and “Capital Structure Complaint” discussed herein.

The cost-based Formula Rates at our Regulated Operating Subsidiaries include a true-up mechanism that compares the actual revenue requirements of our Regulated Operating Subsidiaries to their billed revenues for each year to determine any over- or under-collection of revenue requirements. Revenue is recognized for services provided during each reporting period based on actual revenue requirements calculated using the formula. Our Regulated Operating Subsidiaries accrue or defer revenues to the extent that the actual revenue requirement for the reporting period is higher or lower, respectively, than the amounts billed relating to that reporting period. The amount of accrued or deferred revenues is reflected in future revenue requirements and thus flows through to customer bills within two years under the provisions of our Formula Rates.

The net changes in regulatory assets and liabilities associated with our Regulated Operating Subsidiaries’ Formula Rate revenue accruals and deferrals, including accrued interest, were as follows during the year ended December 31, 2023:

(In millions of USD)	Total
Net regulatory liabilities as of December 31, 2022	$	(20)
Net refund of 2021 revenue deferrals and accruals, including accrued interest	11
Net revenue deferral, including accrued interest	(17)
Net accrued interest payable	(2)
Net regulatory liabilities as of December 31, 2023	$	(28)

Regulatory assets and liabilities associated with our Regulated Operating Subsidiaries’ Formula Rate revenue accruals and deferrals, including accrued interest, are recorded in the consolidated statements of financial position as follows:

	December 31,
(In millions of USD)	2023		2022
Current regulatory assets	$	30	$	12
Non-current regulatory assets	20		29
Current regulatory liabilities	(41)		(22)
Non-current regulatory liabilities	(37)		(39)
Net regulatory liabilities	$	(28)	$	(20)

ROE and Incentive Adders for Transmission Rates

The FERC has authorized the use of ROE incentives, or adders, that can be applied to the rates of TOs when certain conditions are met. Our MISO Regulated Operating Subsidiaries and ITC Great Plains utilize ROE adders related to independent transmission ownership and RTO participation. The FERC issued a NOPR on March 20, 2020, and a supplemental NOPR on April 15, 2021, proposing to update its transmission incentives policy to remove incentives for independent transmission ownership and RTO participation and to grant

55

incentives for certain transmission projects. As of December 31, 2023, no final determination had been made on these NOPRs and we cannot predict whether this will have a material impact on us.

MISO Regulated Operating Subsidiaries

For each of the years ended December 31, 2023, 2022 and 2021, the authorized ROE used by the MISO Regulated Operating Subsidiaries was 10.77% and is composed of a base ROE of 10.02% with a 25 basis point adder for independent transmission ownership and a 50 basis point adder for RTO participation. See “Rate of Return on Equity Complaints” in Note 17 for a discussion of the MISO ROE Complaints.

ITC Great Plains

For each of the years ended December 31, 2023, 2022 and 2021, the authorized ROE used by ITC Great Plains was 11.41% and is composed of a base ROE of 10.66% with a 25 basis point adder for independent transmission ownership and a 50 basis point adder for RTO participation.

Capital Structure Complaint

On May 10, 2022, the Iowa Coalition for Affordable Transmission, including IP&L, filed a complaint with the FERC under Section 206 of the FPA. Specifically, the complaint alleged that ITC Midwest does not meet the FERC’s three-part test for authorizing the use of a utility’s actual capital structure for ratemaking purposes which requires that ITC Midwest 1) issue its own debt without guarantees, 2) have its own credit rating, and 3) have a capital structure within the range of capital structures previously approved by the Commission. The Iowa Coalition for Affordable Transmission asked the FERC to reduce ITC Midwest’s equity component from 60% to 53%. On November 2, 2022, the FERC issued an order denying the complaint. On December 2, 2022, the Iowa Coalition for Affordable Transmission filed a request for rehearing with the FERC. On March 16, 2023, the FERC confirmed the previous order denying the complaint and we consider the matter to be closed.

Depreciation Rate Filings

During 2021, our MISO Regulated Operating Subsidiaries filed revised depreciation rates for their assets which were approved by the FERC in December 2021. The overall depreciation expense at our MISO Regulated Operating Subsidiaries increased beginning on January 1, 2022, which resulted in higher revenue as the increase in depreciation expense flows through to customer bills.

7.    REGULATORY ASSETS AND LIABILITIES

The following table summarizes the regulatory asset and liability balances:

	December 31,
(In millions of USD)	2023		2022
Regulatory assets:
Current:
Revenue accruals (including accrued interest of $2 and less than $1 as of December 31, 2023 and 2022, respectively) (a)	$	30	$	12
Total current	30		12
Non-current:
Revenue accruals (including accrued interest of $1 and less than $1 as of December 31, 2023 and 2022, respectively) (a)	20		29
Income taxes recoverable related to AFUDC equity	130		121
Pensions and postretirement	9		8
Other	16		23
Total non-current	175		181
Total regulatory assets	$	205	$	193
Regulatory liabilities:
Current:
Revenue deferrals (including accrued interest of $3 and $1 as of December 31, 2023 and 2022, respectively) (a)	$	41	$	22
Total current	41		22
Non-current:
Revenue deferrals (including accrued interest of $1 as of December 31, 2023 and 2022) (a)	37		39
Pensions and postretirement	62		52
Accrued asset removal costs	111		80
Refundable excess state income tax deductions	46		25
Refundable excess deferred federal income taxes	465		480
Total non-current	721		676
Total regulatory liabilities	$	762	$	698

____________________________

(a)Refer to discussion of revenue accruals and deferrals in Note 6 under “Cost-Based Formula Rates with True-Up Mechanism.” Our Regulated Operating Subsidiaries do not earn a return on the balance of regulatory assets for revenue accruals. Interest is accrued on the principal amounts of the revenue accruals and deferrals. The accrued interest is subject to rate recovery along with the principal amount of the revenue accrual or subject to refund through rates along with the principal amount of revenue deferrals in future periods.

Income Taxes Recoverable Related to AFUDC Equity

Accounting standards for income taxes provide that a regulatory asset be recorded if it is probable that a future increase in taxes payable, relating to the book depreciation of AFUDC equity that has been capitalized to property, plant and equipment, will be recovered from customers through future rates. The regulatory asset for the tax effects of AFUDC equity is recovered over the life of the underlying book asset in a manner that is consistent with the depreciation of the AFUDC equity that has been capitalized to property, plant and equipment.

57

Pensions and Postretirement

Accounting standards for defined benefit pension and other postretirement plans for rate-regulated entities allow for amounts that otherwise would have been recorded to AOCI to be recorded as regulatory assets or liabilities, as appropriate. As the unrecognized amounts recorded to these regulatory assets and liabilities are recognized, the amounts will be recovered from or returned to customers in future rates under our cost-based Formula Rates.

Accrued Asset Removal Costs

The carrying amount of the accrued asset removal costs represents the difference between incurred costs to remove property, plant and equipment and the estimated removal costs included and collected in rates. The portions of depreciation expense included in our depreciation rates related to asset removal costs are recorded as increases to the related regulatory liability. Removal costs incurred reduce the related regulatory liability. Our Regulated Operating Subsidiaries include these regulatory liabilities as increases to accumulated depreciation for rate-making purposes when determining rate base.

Refundable Excess State Income Tax Deductions

As a result of a reduction in corporate income tax rates in certain states we operate in, we revalued our deferred tax balances at the new corporate income tax rates, which resulted in lower net deferred tax liabilities and the recording of a regulatory liability for excess deferred taxes at our Regulated Operating Subsidiaries. Amortization of the excess deferred taxes is determined based on the remaining book lives of utility plant. During the years ended December 31, 2023 and 2022, we recorded $1 million and less than $1 million of amortization related to the excess deferred taxes, respectively. This regulatory liability is included within deferred taxes for rate-making purposes when determining rate base.

Refundable Excess Deferred Federal Income Taxes

Under the Tax Cuts and Jobs Act of 2017, we were required to revalue our deferred tax assets and liabilities at the new federal corporate income tax rate as of the date of the enactment of the act, which resulted in lower net deferred tax liabilities and the establishment of a net regulatory liability for excess deferred taxes at our Regulated Operating Subsidiaries. Amortization of the excess deferred taxes is determined based on a method associated with the related public utility property and returned to customers. During each of the years ended December 31, 2023 and 2022, we recorded $9 million of amortization related to the excess deferred taxes. The net regulatory liability is included within deferred taxes for rate-making purposes when determining rate base.

8.    PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment, net consisted of the following:

	December 31,
(In millions of USD)	2023		2022
Property, plant and equipment

Derivative Instruments and Hedging Activities

During the second quarter of 2023, we entered into and terminated 10-year U.S. Treasury rate lock contracts with notional amounts totaling $500 million and a weighted-average forward rate yield of 3.46%. The contracts were used to manage interest rate risk associated with the $500 million issuance of unsecured 5.40% Senior Notes at ITC Holdings on June 1, 2023. The comparable reference rate used to determine the gain on settlement of the treasury locks was 3.57%. The treasury locks qualified for cash flow hedge accounting treatment and the cumulative pre-tax gain of $4 million was recorded net of tax in AOCI. This amount is being amortized as a component of interest expense over the term of the related debt. The settlement payment was recognized within cash flows from operating activities in the consolidated statements of cash flows.

61

During 2022, we terminated $450 million of 5-year interest rate swap contracts that managed interest rate risk associated with the ITC Holdings 4.95% Senior Notes, due September 22, 2027. A summary of the terminated interest rate swaps is provided below:

(In millions of USD, except percentages)	Notional Amount		Weighted Average Fixed Rate of Interest Rate Swaps	Comparable Reference Rate of Notes	Benchmark Rate	Gain on Derivatives		Settlement Date
5-year interest rate swaps	$	375	1.47%	3.44%	LIBOR	$	33	September 2022
5-year interest rate swaps	75		1.54%	3.16%	SOFR	6		September 2022
Total	$	450				$	39

The interest rate swaps qualified for cash flow hedge accounting treatment, and the cumulative pre-tax gain of $39 million was recorded net of tax in AOCI. This amount is being amortized as a component of interest expense over the term of the related debt. The swap settlement payment was recognized within cash flows from operating activities in the consolidated statements of cash flows. For the years ended December 31, 2023 and 2022, we did not have any derivative financial instruments outstanding to manage exposure to fluctuations in interest rates.

Revolving Credit Agreement

On April 14, 2023, ITC Holdings, ITCTransmission, METC, ITC Midwest and ITC Great Plains entered into the Revolving Credit Agreement. In connection with the closing of the Revolving Credit Agreement, the borrowers used funds borrowed under the Revolving Credit Agreement to replace and refinance in full the previous revolving credit agreements. The Revolving Credit Agreement established an unguaranteed, unsecured revolving credit facility under which the borrowers may borrow an aggregate principal amount of $1 billion (subject to certain borrowing sublimits for each of the borrowers as set forth in the Revolving Credit Agreement). The Revolving Credit Agreement has a maturity date of April 14, 2028 and the interest rate is based on a calculation that references, at the applicable borrower’s option, either SOFR or a comparable benchmark as further outlined in the Revolving Credit Agreement.

At December 31, 2023, ITC Holdings and certain of its Regulated Operating Subsidiaries had the following unsecured revolving credit facilities available:

(In millions of USD, except percentages)	Total Available Capacity (a)		Outstanding Balance (b)		Unused Capacity		Weighted Average Interest Rate on Outstanding Balance (c)	Commitment Fee Rate (d)

10.    INCOME TAXES

For the years ended December 31, 2023, 2022 and 2021, our effective tax rates were 25.2%, 24.8% and 23.8%, respectively. Our effective tax rate varied from the statutory federal income tax rate due to differences between the book and tax treatment of various transactions as follows:

	Year Ended December 31,
(In millions of USD)	2023		2022		2021
Income tax expense at 21% federal statutory rate	$	130	$	123	$	112
State income taxes (net of federal benefit) (a)	43		36		24
AFUDC equity	(7)		(6)		(5)
Amortization of revalued deferred federal income taxes	(9)		(9)		(9)
Valuation allowance	(2)		1		4
Other, net	1		1		1
Total income tax provision	$	156	$	146	$	127

____________________________

(a)Amounts for the years ended December 31, 2023 and 2022 include the impact of the remeasurement of certain deferred tax balances and NOLs for Iowa due to the corporate tax rate change discussed herein.

Components of the income tax provision were as follows:

	Year Ended December 31,
(In millions of USD)	2023		2022		2021
Current income tax expense	$	51	$	15	$	—
Deferred income tax expense	105		131		127
Total income tax provision	$	156	$	146	$	127

Deferred income tax assets (liabilities) consisted of the following:

	December 31,
(In millions of USD)	2023		2022
Property, plant and equipment	$	(1,461)	$	(1,363)
Goodwill	(148)		(148)
Regulatory liability gross up due to change in federal income tax rate	119		125
Pension and postretirement liabilities	22		24
State income tax NOLs (net of federal benefit)	39		47
Valuation allowance	(3)		(5)
Other, net	21		17
Net deferred tax liabilities	$	(1,411)	$	(1,303)
Gross deferred income tax liabilities	$	(1,642)	$	(1,542)
Gross deferred income tax assets	234		244
Valuation allowance	(3)		(5)
Net deferred tax liabilities	$	(1,411)	$	(1,303)

We had state income tax NOLs as of December 31, 2023. While we expect to utilize the majority of these state NOLs prior to their expiration, we believe that it is more likely than not that the benefit from certain state NOL carryforwards will not be realized and have recorded a valuation allowance accordingly.

Iowa Corporate Tax Rate

On March 1, 2022, the governor of Iowa signed an act into law that contains provisions to reduce Iowa’s corporate tax rates if a certain threshold of the state’s annual net corporate income tax receipts is met.

63

Adjustments to reduce the corporate income tax rate are calculated annually after the end of each fiscal year and may continue until the currently targeted corporate income tax rate of 5.5% is reached.

For Iowa’s fiscal year ended June 30, 2023, net corporate income tax receipts exceeded the prescribed threshold. On September 22, 2023, the Iowa Department of Revenue certified a reduction in the top corporate income tax rate from 8.4% to 7.1%, effective January 1, 2024. We have revalued certain deferred tax balances and net operating losses impacted by the change in the future Iowa corporate income tax rate. As a result, deferred income tax expense of $6 million was recorded during the year ended December 31, 2023. In addition, a regulatory liability of $21 million was recorded as of December 31, 2023 to offset deferred taxes associated with rate base at ITC Midwest.

In September 2022, a reduction in Iowa’s top corporate income tax rate from 9.8% to 8.4% was certified, effective January 1, 2023. As a result, deferred income tax expense of $7 million was recorded during the year ended December 31, 2022 and a regulatory liability of $22 million was recorded as of December 31, 2022 to offset deferred taxes associated with the rate base at ITC Midwest. See Note 7 for additional information on the regulatory liabilities related to the Iowa corporate income tax rate reductions.

11.    RETIREMENT BENEFITS AND ASSETS HELD IN TRUST

Pension and Postretirement Plan Benefits

We have a qualified defined benefit pension plan (“retirement plan”) for eligible employees, comprised of a traditional final average pay plan and a cash balance plan. The traditional final average pay plan is noncontributory, covers select employees, and provides retirement benefits based on years of benefit service, average final compensation, and age at retirement. The cash balance plan is also noncontributory, covers substantially all employees and provides retirement benefits based on eligible compensation and interest credits. Our funding practice for the retirement plan is generally to fund the annual net pension cost, though we may adjust our funding as necessary based on consideration of federal funding requirements, the funded status of the plan, and other considerations as we deem appropriate. We did not contribute to the retirement plan in 2023. We made contributions to the retirement plan of $3 million and $4 million in 2022 and 2021, respectively. We expect to contribute $4 million to the retirement plan in 2024.

We also have two supplemental nonqualified, noncontributory, defined benefit pension plans for selected management employees (the “supplemental benefit plans” and collectively with the retirement plan, the “pension plans”). The supplemental benefit plans provide for benefits that supplement those provided by the retirement plan. The obligations under these supplemental benefit plans are included in the pension benefit obligation calculations below. The investments held in trust for the supplemental benefit plans of $48 million and $47 million at December 31, 2023 and 2022, respectively, are not included in the plan asset amounts presented throughout this footnote, but are included in other assets on our consolidated statements of financial position. For the years ended December 31, 2023 and 2021, we contributed $1 million and $3 million, respectively, to these supplemental benefit plans. We did not contribute to the supplemental benefit plans in 2022.

We provide certain postretirement health care, dental, and life insurance benefits for eligible employees (the “postretirement benefit plan”). We contributed $1 million, $7 million, and $8 million to the postretirement benefit plan in 2023, 2022, and 2021, respectively. We expect to contribute $2 million to the postretirement benefit plan in 2024.

64

Net periodic benefit costs by component for the pension plans and postretirement benefit plan were as follows:

	Pension Plans						Postretirement Benefit Plan
	Year Ended December 31,						Year Ended December 31,
(In millions of USD)	2023		2022		2021		2023		2022		2021

Total	$	—	$	(2)	$	(62)	$	(50)

The unrecognized amounts that otherwise would have been charged and/or credited to AOCI in accordance with the GAAP guidance on accounting for retirement benefits are recorded as a regulatory asset or regulatory liability on our consolidated statements of financial position, as discussed in Note 7. The amounts recorded as a regulatory asset or regulatory liability represent a net periodic benefit cost or credit to be recognized in our operating income in future periods. Our measurement of the accumulated benefit obligation for the postretirement benefit plan as of December 31, 2023 and December 31, 2022 reflects anticipated future receipts of subsidies under the Medicare Prescription Drug, Improvement and Modernization Act of 2003, which

66

we have applied for beginning in 2023. The initial reflection of the subsidy as of December 31, 2022 resulted in a reduction in the accumulated postretirement benefit obligation of $7 million related to benefits attributed to past services.

The net actuarial loss for the year ended December 31, 2023 within the change in benefit obligation for the pension plans is primarily the result of decreases in the discount rates and increases in the rate of salary increases and the interest crediting rate. The net actuarial gains for the year ended December 31, 2022 within the change in benefit obligation for both the pension plans and postretirement benefit plan are primarily the result of increases in the discount rates.

The combined projected benefit obligation and fair value of plan assets for those plans in which the projected benefit obligation is in excess of the fair value of plan assets are as follows:

	Pension Plans
	December 31,
(In millions of USD)	2023		2022

Actuarial assumptions used to determine the benefit cost for the pension plans and postretirement benefit plan are as follows:

	Pension Plans			Postretirement Benefit Plan
	Year Ended December 31,			Year Ended December 31,
	2023	2022	2021	2023	2022	2021

Investment Objectives and Fair Value Measurement

The general investment objectives of the retirement plan and postretirement benefit plan include maximizing the return within reasonable and prudent levels of risk and controlling administrative and management costs. Investment decisions are made by our retirement benefits board as delegated by our board of directors. Equity investments may include various types of U.S. and international equity securities, such as large-cap, mid-cap, and small-cap stocks. Fixed income investments may include cash and short-term instruments, U.S. Government securities, corporate bonds, mortgages, and other fixed income investments. No investments are prohibited for use in the retirement plan or postretirement benefit plan, including derivatives, but our exposure to derivatives currently is not material. We intend that the long-term capital growth of the retirement and postretirement benefit plans, together with employer contributions, will provide for the payment of the benefit obligations.

As of December 31, 2023 and 2022, the plan assets of the retirement plan and postretirement benefit plan consisted of the following assets by category:

	Target Allocation		Pension Plans				Postretirement Benefit Plan
Asset Category	2023		2023		2022		2023		2022
Fixed income securities	50	%	50	%	50	%	50	%	50	%
Equity securities	50	%	50	%	50	%	50	%	50	%
Total	100	%	100	%	100	%	100	%	100	%

68

We determine our expected long-term rate of return on plan assets based on the current and expected target allocations of the retirement plan and postretirement benefit plan investments and considering historical and expected long-term rates of return on comparable fixed income investments and equity investments.

The measurement of fair value is based on a three-tier hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs, such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore, requiring an entity to develop its own assumptions. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. For the years ended December 31, 2023 and 2022, there were no transfers between levels.

For the years ended December 31, 2023 and 2022, the fair value of retirement plan and postretirement benefit plan assets measured on a recurring basis at the Level 1 tier were as follows:

	Pension Plans				Postretirement Benefit Plan
	December 31,				December 31,
(In millions of USD)	2023		2022		2023		2022
Mutual funds — U.S. equity securities	$	42	$	38	$	68	$	59
Mutual funds — international equity securities	11		10		3		3
Mutual funds — fixed income securities	52		48		70		61
Total	$	105	$	96	$	141	$	123

The mutual funds consist primarily of publicly traded mutual funds and are recorded at fair value based on observable trades for identical securities in an active market.

Defined Contribution Plan

We also sponsor a defined contribution retirement savings plan. Participation in this plan is available to substantially all employees. We match employee contributions up to certain predefined limits based upon eligible compensation and the employee’s contribution rate. The cost of this plan was $7 million, $7 million, and $6 million for the years ended December 31, 2023, 2022, and 2021, respectively.

12.    FAIR VALUE MEASUREMENTS

The measurement of fair value is based on a three-tier hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. For the years ended December 31, 2023 and 2022, there were no transfers between levels.

Our assets measured at fair value subject to the three-tier hierarchy at December 31, 2023, were as follows:

	Fair Value Measurements at Reporting Date Using
	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
(In millions of USD)	(Level 1)		(Level 2)		(Level 3)
Financial assets measured on a recurring basis:
Mutual funds — fixed income securities	$	44	$	—	$	—
Mutual funds — equity securities	14		—		—
Total	$	58	$	—	$	—

69

Our assets measured at fair value subject to the three-tier hierarchy at December 31, 2022, were as follows:

	Fair Value Measurements at Reporting Date Using
	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
(In millions of USD)	(Level 1)		(Level 2)		(Level 3)
Financial assets measured on a recurring basis:
Mutual funds — fixed income securities	$	44	$	—	$	—
Mutual funds — equity securities	11		—		—
Total	$	55	$	—	$	—

As of December 31, 2023 and 2022, we held certain assets that are required to be measured at fair value on a recurring basis. The assets consist of investments recorded within cash and cash equivalents and other long-term assets, including investments held in a trust associated with our supplemental benefit plans described in Note 11 and certain deferred compensation plan investments. The mutual funds we own are publicly traded and are recorded at fair value based on observable trades for identical securities in an active market. Changes in the observed trading prices and liquidity of money market funds are monitored as additional support for determining fair value.

We also held non-financial assets that are required to be measured at fair value on a non-recurring basis. These consist of goodwill and intangible assets. We did not record any impairment charges on long-lived assets and no other significant events occurred requiring non-financial assets and liabilities to be measured at fair value (subsequent to initial recognition) during the years ended December 31, 2023 and 2022.

Fair Value of Financial Assets and Liabilities

Fixed Rate Debt

Based on the borrowing rates obtained from third party lending institutions currently available for bank loans with similar terms and average maturities from active markets, the fair value of our consolidated long-term debt and debt maturing within one year, excluding revolving credit agreements and commercial paper, was $6,660 million and $5,849 million at December 31, 2023 and 2022, respectively. These fair values represent Level 2 under the three-tier hierarchy described above. The total book value of our consolidated long-term debt and debt maturing within one year, net of discount and deferred financing fees and excluding revolving credit agreements and commercial paper, was $7,287 million and $6,649 million at December 31, 2023 and 2022, respectively.

Revolving Credit Agreements

At December 31, 2023 and 2022, we had a consolidated total of $311 million and $208 million, respectively, outstanding under our revolving credit agreements, which are variable rate loans. The fair value of these loans approximates book value based on the borrowing rates currently available for variable rate loans obtained from third party lending institutions. These fair values represent Level 2 under the three-tier hierarchy described above. See Note 9 for changes to our revolving credit agreements since December 31, 2022.

Other Financial Instruments

The carrying value of other financial instruments included in current assets and current liabilities, including cash and cash equivalents, special deposits and commercial paper, approximates their fair value due to the short-term nature of these instruments.

Long-Term Incentive Plans

Performance-Based Units

The PBUs are measured at fair value at the end of each reporting period, which will fluctuate based on the price of Fortis common stock and the level of achievement of the financial performance criteria, including a market condition and a performance condition. The payout may range from 0% - 200% of the target award, depending on actual performance relative to the performance criteria. The PBUs earn dividend equivalents which are also re-measured consistent with the target award and settled in cash at the end of the vesting period.

71

The following table shows the changes in PBUs during the year ended December 31, 2023:

	Number of
	Performance
	Based Units
PBUs at December 31, 2022	819,391
Granted	340,688
Vested and paid out	(278,974)
Forfeited	(30,057)
PBUs at December 31, 2023	851,048

Other long-term liabilities	12		16
Total	$	30	$	35

The aggregate fair value of PBUs as of December 31, 2023 and 2022 was $40 million and $46 million, respectively. At December 31, 2023, $10 million of total unrecognized compensation cost related to PBUs not yet vested is expected to be recognized over the remaining weighted average period of 1.7 years.

Service-Based Units

The SBUs are measured at fair value at the end of each reporting period, which will fluctuate based on the price of Fortis common stock. The SBUs earn dividend equivalents which are also re-measured based on the price of Fortis common stock and settled in cash at the end of the vesting period.

The following table shows the changes in SBUs during the year ended December 31, 2023:

	Number of
	Service
	Based Units
SBUs at December 31, 2022	630,269

16.    RELATED PARTY TRANSACTIONS

Related Party Receivables and Payables

ITC Holdings may incur charges from Fortis and other subsidiaries of Fortis that are not subsidiaries of ITC Holdings for general corporate expenses incurred. In addition, ITC Holdings may perform additional services for, or receive additional services from, Fortis and such subsidiaries. These transactions are in the normal course of business and payments for these services are settled through accounts receivable and accounts payable, as necessary. We had receivables from Fortis and such subsidiaries of $1 million at December 31, 2023 and 2022, and payables to Fortis and such subsidiaries of less than $1 million and $1 million at December 31, 2023 and 2022, respectively.

Related party charges for corporate expenses from Fortis and such subsidiaries are recorded in general and administrative expense. ITC Holdings had such expense for the years ended December 31, 2023, 2022 and 2021 of $12 million, $13 million and $10 million, respectively. Related party billings for services to Fortis and other subsidiaries recorded as an offset to general and administrative expenses for ITC Holdings were $3 million for the year ended December 31, 2023 and $2 million for each of the years ended December 31, 2022 and 2021.

Dividends

We paid dividends of $283 million, $273 million and $232 million during the years ended December 31, 2023, 2022 and 2021, respectively, to ITC Investment Holdings. ITC Holdings also paid dividends of $86 million to ITC Investment Holdings in January 2024.

Intercompany Tax Sharing Agreement

We are organized as a corporation for tax purposes and subject to a tax sharing agreement as a wholly-owned subsidiary of ITC Investment Holdings. Additionally, we record income taxes based on our separate company tax position and make or receive tax-related payments with ITC Investment Holdings. During the years ended December 31, 2023 and 2022, we paid $49 million and $11 million, respectively, to ITC Investment Holdings associated with our income tax position.

17.    COMMITMENTS AND CONTINGENT LIABILITIES

Environmental Matters

We are subject to federal, state and local environmental laws and regulations, which impose limitations on the discharge of pollutants into the environment, require reporting of emissions from certain equipment, establish standards for the management, treatment, storage, transportation and disposal of hazardous materials and of solid and hazardous wastes, and impose obligations to investigate and remediate contamination in certain circumstances. Liabilities relating to investigation and remediation of contamination, as well as other liabilities concerning hazardous materials or contamination, such as claims for personal injury or property damage, may arise at many locations, including formerly owned or operated properties and sites where wastes have been treated or disposed of, as well as properties currently owned or operated by us. Such liabilities may arise even where the contamination does not result from noncompliance with applicable environmental laws. Under some environmental laws, such liabilities may also be joint and several, meaning that a party can be held responsible for more than its share of the liability involved, or even the entire share. Although environmental requirements generally have become more stringent and compliance with those requirements more expensive, we are not aware of any specific developments that would increase our costs for such compliance in a manner that would be expected to have a material adverse effect on our financial condition, results of operations or liquidity.

Our assets and operations also involve the use of materials classified as hazardous, toxic or otherwise dangerous. Some of the properties that we own or operate have been used for many years and include older facilities and equipment that may be more likely than newer ones to contain or be made from such materials. Some of these properties include above ground or underground storage tanks and associated piping. Some of them also include large electrical equipment filled with mineral oil, which may contain or previously have contained PCBs. Some of our facilities and electrical equipment may also contain asbestos containing materials. Our facilities and equipment are often situated close to or on property owned by others so that, if they are the source of contamination, the property of others may be affected. For example, above ground and underground transmission lines sometimes traverse properties that we do not own and transmission assets that we own or operate are sometimes commingled at our transmission stations with distribution assets owned or operated by our transmission customers.

Some properties in which we have an ownership interest or at which we operate are, or are suspected of being, affected by environmental contamination. We are not aware of any pending or threatened claims against us with respect to environmental contamination relating to these properties, or of any investigation or remediation of contamination at these properties, that entail costs likely to materially affect us. Some facilities and properties are located near environmentally sensitive areas, including wetlands and habitat for threatened and endangered species.

Litigation

We are involved in certain legal proceedings before various courts, governmental agencies and mediation panels concerning matters arising in the ordinary course of business. These proceedings include certain contract disputes, eminent domain and vegetation management activities, regulatory matters and pending judicial matters. We cannot predict the final disposition of such proceedings. We regularly review legal matters and record provisions for claims that are considered probable of loss.

Rate of Return on Equity Complaints

Two complaints were filed with the FERC by combinations of consumer advocates, consumer groups, municipal parties and other parties challenging the base ROE in MISO. The complaints were filed with the FERC under Section 206 of the FPA requesting that the FERC find the MISO regional base ROE rate (the “base ROE”) for all MISO TO’s, including our MISO Regulated Operating Subsidiaries, to no longer be just and reasonable.

Initial Complaint

On November 12, 2013, the Association of Businesses Advocating Tariff Equity, Coalition of MISO Transmission Customers, Illinois Industrial Energy Consumers, Indiana Industrial Energy Consumers, Inc., Minnesota Large Industrial Group and Wisconsin Industrial Energy Group (collectively, the “complainants”) filed the Initial Complaint with the FERC. The complainants sought a FERC order to reduce the base ROE used in

74

the formula transmission rates for our MISO Regulated Operating Subsidiaries to 9.15%, reducing the equity component of our capital structure and terminating the ROE adders approved for certain MISO Regulated Operating Subsidiaries. The FERC set the base ROE for hearing and settlement procedures, while denying all other aspects of the Initial Complaint. The ROE collected through the MISO Regulated Operating Subsidiaries’ rates during the period November 12, 2013 through September 27, 2016 consisted of a base ROE of 12.38% plus applicable incentive adders.

Second Complaint

On February 12, 2015, the Second Complaint was filed with the FERC by Arkansas Electric Cooperative Corporation, Mississippi Delta Energy Agency, Clarksdale Public Utilities Commission, Public Service Commission of Yazoo City and Hoosier Energy Rural Electric Cooperative, Inc., seeking a FERC order to reduce the base ROE used in the formula transmission rates of our MISO Regulated Operating Subsidiaries to 8.67%, with an effective date of February 12, 2015.

On June 30, 2016, the presiding ALJ issued an initial decision that recommended a base ROE of 9.70% for the refund period from February 12, 2015 through May 11, 2016, with a maximum ROE of 10.68%, which also would be applicable going forward from the date of a final FERC order. The Second Complaint was dismissed as a result of an order issued by the FERC on November 21, 2019 and the dismissal of the complaint was reaffirmed in the May 2020 Order.

FERC Orders

Since the filing of the Initial Complaint, the FERC has issued separate orders in these proceedings on September 28, 2016, November 21, 2019 and May 21, 2020. These orders resulted in multiple revisions to the base ROE and refund settlements. The MISO TOs, along with our MISO Regulated Operating Subsidiaries, and other various parties have challenged certain aspects of these orders through requests for rehearing. In the most recent order, the FERC determined that a methodology using three financial models should be used to determine the base ROE. By applying the new methodology, the FERC determined that the base ROE for the Initial Complaint should be 10.02% and the top of the range of reasonableness for that period should be 12.62%. The FERC determined that this base ROE should apply during the first refund period of November 12, 2013 to February 11, 2015 and from the date of the order issued by the FERC on September 28, 2016 prospectively. The FERC ordered refunds to be made in accordance with the May 2020 Order. Refund settlements were finalized by March 31, 2022, and during the year ended December 31, 2022, we received net settlement payments of less than $1 million owed from customers.

August 2022 D.C. Circuit Court Decision

On August 9, 2022, in response to appeals of the FERC's orders on the MISO ROE Complaints, the D.C. Circuit Court issued an opinion that rejected the FERC’s use of a risk premium model in the methodology used to determine the revised base ROE for MISO TOs. The D.C. Circuit Court decision vacated the FERC’s orders on the MISO ROE Complaints, dismissed the remaining outstanding appeals of these orders and remanded the matter to the FERC for further proceedings.

It is possible that the base ROE established in the May 2020 Order may be revised and that we could be required to provide additional material refunds upon resolution of the proceedings. We are awaiting action by the FERC in these proceedings to provide further insight into possible changes to our base ROE and the periods for which a revised ROE applies. We cannot predict whether these proceedings will have a material impact, or estimate the possible impact, on our financial condition, results of operations or cash flows.

See Note 6 for a summary of our base ROE and incentive adders for transmission rates. As of December 31, 2023, our MISO Regulated Operating Subsidiaries had a total of approximately $5 billion of equity in their collective capital structures for ratemaking purposes. Based on this level of aggregate equity, we estimate that each 10 basis point change in the authorized ROE would impact annual consolidated net income by approximately $5 million.

Purchase Obligations

At December 31, 2023, we had purchase obligations of $115 million representing commitments for materials, services and equipment that had not been received as of December 31, 2023, primarily for construction and maintenance projects for which we have an executed contract. Of these purchase obligations, $99 million is

75

expected to be paid in 2024, with the majority of the items related to materials and equipment that have long production lead times.

Other Commitments

METC

Amended and Restated Purchase and Sale Agreement for Ancillary Services. Since METC does not own any generating facilities, it must procure ancillary services from third party suppliers, such as Consumers Energy. Currently, under the Ancillary Services Agreement, METC pays Consumers Energy for providing certain generation-based services necessary to support the reliable operation of the bulk power grid, such as voltage support and generation capability and capacity to balance loads and generation.

Amended and Restated Easement Agreement. Under the Easement Agreement, Consumers Energy provides METC with an easement to the land on which a majority of METC’s transmission towers, poles, lines and other transmission facilities used to transmit electricity for Consumers Energy and others are located. The term of the Easement Agreement runs through December 31, 2050 and is subject to 10 automatic 50-year renewals thereafter unless METC gives notice of nonrenewal at least one year in advance. METC pays Consumers Energy $10 million in annual rent per year for the easement and also pays for any rentals, property, taxes, and other fees related to the property covered by the Easement Agreement. Payments to Consumers Energy under the Easement Agreement are charged to operation and maintenance expense in our consolidated statements of comprehensive income.

ITC Midwest

Operations Services Agreement For 34.5 kV Transmission Facilities. ITC Midwest and IP&L entered into the OSA under which IP&L performs certain operations functions for ITC Midwest’s 34.5 kV transmission system.

ITC Great Plains

Amended and Restated Maintenance Agreement. Sunflower and ITC Great Plains have entered into the Sunflower Agreement pursuant to which Sunflower has agreed to perform various field operations and maintenance services related to certain ITC Great Plains assets.

Concentration of Credit Risk

Our credit risk is primarily with DTE Electric, Consumers Energy and IP&L, which were responsible for approximately 21.7%, 21.3% and 24.5%, respectively, or $338 million, $332 million and $382 million, respectively, of our consolidated billed revenues for the year ended December 31, 2023. This portion of total billed revenues of DTE Electric, Consumers Energy and IP&L include the refund of 2021 revenue accruals and deferrals and exclude any amounts for the 2023 revenue accruals and deferrals that were included in our 2023 operating revenues but will not be billed to our customers until 2025. Under DTE Electric’s and Consumers Energy’s current rate structure, DTE Electric and Consumers Energy include in their retail rates the actual cost of transmission services provided by ITCTransmission and METC, respectively, in their billings to their customers, effectively passing through to end-use consumers the total cost of transmission service. IP&L currently includes in their retail rates an allowance for transmission services provided by ITC Midwest in their billings to their customers. However, any financial difficulties experienced by DTE Electric, Consumers Energy or IP&L may affect their ability to make payments for transmission service to ITCTransmission, METC, and ITC Midwest, which could negatively impact our business. MISO, as our MISO Regulated Operating Subsidiaries’ billing agent, bills DTE Electric, Consumers Energy, IP&L and other customers on a monthly basis and collects fees for the use of the MISO Regulated Operating Subsidiaries’ transmission systems. SPP is the billing agent for ITC Great Plains and bills transmission customers for the use of ITC Great Plains transmission systems. MISO and SPP have implemented strict credit policies for its members’ customers, which include customers using our transmission systems. Specifically, MISO and SPP require a letter of credit or cash deposit equal to the credit exposure, which is determined by a credit scoring model and other factors, from any customer using a member’s transmission system.

None.

ITEM 9A.     CONTROLS AND PROCEDURES.

Management’s Report on Internal Control Over Financial Reporting is included in Item 8. of this Form 10-K.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that material information required to be disclosed in our reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required financial disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, with a company have been detected.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15 of the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective, at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B.     OTHER INFORMATION.

The following Compensation Discussion and Analysis describes the elements of compensation for our Chief Executive Officer (or “CEO”), our Chief Financial Officer and the three other most highly compensated executive officers who were serving as such at December 31, 2023. We refer to these individuals collectively as the “named executive officers” (or “NEOs”).

84

The Company’s named executive officers for 2023 were:

Name	Position
Linda H. Apsey	President and Chief Executive Officer
Gretchen L. Holloway	Senior Vice President and Chief Financial Officer

Christine Mason Soneral	Senior Vice President, General Counsel, Corporate Secretary and Chief Compliance Officer
Krista Tanner	Senior Vice Present and Chief Business Officer

Executive Summary

The Governance and Human Resources Committee (the “Committee”) is responsible for determining the compensation of our NEOs and administering the plans in which the NEOs participate. The goals of our compensation system are to attract first-class executive talent in a competitive environment and to motivate and retain key employees who are crucial to our success by rewarding Company and individual performance that promotes long-term sustainable growth and increases Fortis shareholder value. The key components of our NEOs' compensation package include base salary, annual cash incentive bonuses, long-term equity incentives, as well as certain perquisites and other benefits. In determining the amount of NEO compensation, we consider competitive compensation practices of other utilities and similarly sized organizations, the executive's individual performance against objectives, the executive's responsibilities and expertise, and our performance in relation to annual goals that are designed to strengthen and enhance our value.

The Committee made the following decisions with regard to executive compensation in 2023:

•Base salary increases. Base salary increases were provided to each of our NEOs in 2023 to reward individual performance and to remain competitive and aligned with market.

•Annual cash incentive bonuses. The NEOs earned cash incentive bonuses for 2023 performance of approximately 111% of target. This was based on achieving 100% of the performance targets established under the ACPB in early 2023 and achievement of certain performance factors which resulted in a bonus multiplier of 1.11x. See “Compensation Discussion and Analysis - Key Components of Our NEO Compensation Program - Annual Corporate Performance Bonus.”

•Long-term equity incentives. We granted long-term equity incentive awards to our NEOs effective January 2023. Total award opportunities were set as a percentage of base salary and delivered one-third in the form of SBUs and two-thirds in the form of PBUs.

Overview and Philosophy

The objectives of our compensation program are to attract first-class executive talent in a competitive environment and to motivate and retain key employees who are crucial to our success by rewarding Company and individual performance that promotes long-term sustainable growth and increases Fortis shareholder value by:

•Performing best-in-class utility operations;

•Improving reliability, reducing congestion, and facilitating access to generation resources; and

•Utilizing our experience and skills to seek and identify opportunities to invest in needed transmission and to optimize the value of those investments.

Our compensation program is designed to motivate and reward individual and corporate performance. Our compensation philosophy is to:

•Provide for flexibility in pay practices to recognize our unique position and growth proposition;

•Use a market-based pay program aligned with pay-for-performance objectives;

•Leverage incentives, where possible, and align long-term equity incentive awards with improvements in our financial performance and Fortis shareholder value;

85

•Provide benefits through flexible, cost-effective plans while taking into account business needs and affordability; and

•Provide other non-monetary awards to recognize and incentivize performance.

Risk and Reward Balance

When reviewing the compensation program, the Committee considers the impact of the program on the Company’s risk profile. The Committee believes that the compensation program has been structured with the appropriate mix and design of elements to provide strong incentives for executives to balance risk and reward, without excessive risk taking.

The Committee engaged FW Cook, its independent compensation consultant, to conduct an annual comprehensive compensation program risk assessment. In July 2023, FW Cook reviewed the attributes and structure of our executive compensation programs for the purpose of identifying potential sources of risk within the program design. The review covered compensation plan design and administration/governance risk.

Based on its own analysis and a report from FW Cook concluding that the Company’s compensation programs do not create risks that are reasonably likely to have a material adverse impact on the Company, the Committee concluded that none of our compensation programs and features contain elements that create material risk to the Company. Risk mitigating factors with respect to the Company’s compensation programs included a market competitive pay mix, the linking of pay to performance through annual cash bonus and long-term equity incentive plans, caps on annual cash bonus and long-term equity incentive plan payouts, various performance measures that are both financially and operationally focused, stock ownership guidelines, prohibition on hedging and pledging, oversight by an independent committee of directors, regular review of NEO tally sheets and engagement of an independent compensation consultant.

Benchmarking and Relationship of Compensation Elements

Benchmarking. We reviewed market competitive target pay levels from two distinct market samples, utility and general industry data, as reflected in published surveys. FW Cook compiled data for the following components of compensation — base salary, target annual cash bonus incentive and target long-term incentive, as well as target total cash compensation and target total direct compensation. Position-specific market target pay levels are reviewed for utility-specific data from the Willis Towers Watson Energy Services Executive Compensation Survey and general industry data from the Willis Towers Watson General Industry Executive Compensation Survey. The energy services data is used as our primary source with the general industry data provided as an additional reference point for positions other than those specific to the utility industry. The market data were aged and size-adjusted to correspond to our adjusted revenue scope. The adjusted revenue scope accounts for our unique business model and reflects the competitive incremental revenue that would normally be embedded in rates to reflect a typical cost of goods sold factor.

Our compensation strategy is to target compensation at the median (50th percentile) of the energy services benchmark data, plus or minus 20%, based on consideration of individual characteristics (performance, experience, etc.), internal equity and other factors. The Committee adopted this strategy in October 2019. In November 2022, the Committee reviewed the benchmarking study conducted by its independent consultant comparing NEO target total direct compensation, which is the sum of base salary, target annual incentives and target long-term incentives, to the 25th, 50th and 75th percentile survey data to assess the market competitiveness of our compensation opportunities. Overall, the study found target total direct compensation provided to our NEOs varied with certain executives positioned within the targeted competitive range, and in some cases, exceeded the targeted competitive position. Competitive positioning reflects a combination of 25th percentile to median base salaries, above median target bonus as a percent of base salary and median long-term equity incentive opportunities. The Committee continues to monitor and balance competitive practices, talent needs and cost considerations when setting compensation.

Use of Tally Sheets. The Committee reviews tally sheets, every other year, as prepared by management to facilitate its assessment of the total annual compensation of our NEOs. The tally sheets contain annual cash compensation (salary and bonuses), long-term equity incentives, benefit contributions and perquisites. In addition, the tally sheets include retirement program balances, outstanding vested and unvested equity values and potential severance and termination scenario values.

86

Pay Review Process. In addition to the Committee’s benchmarking analysis, our CEO reviewed and examined market survey compensation levels and practices, as well as individual responsibilities and performance, our compensation philosophy and other related information to develop proposed compensation for each of our NEOs, other than herself. Ms. Apsey evaluated the performance of the NEOs, other than herself, and made recommendations on their salaries, target cash bonus incentive levels and long-term equity incentive awards. The Committee considered these recommendations in its decision making and conferred with FW Cook to understand the impact and result of any such recommendations. The Committee uses market data from FW Cook and makes recommendations on Ms. Apsey’s salary, cash bonus incentive targets and long-term equity incentive awards to the Board of Directors. The Board of Directors (other than Ms. Apsey) evaluates Ms. Apsey’s performance and considers the Committee’s recommendations in its decision making.

The Committee reviewed and considered each element of compensation and the resulting target total direct compensation, along with the objectives of our compensation program, the input of the CEO and the market data to set the 2023 target pay levels. The Committee did not determine the mix of compensation elements using a pre-set formula. In setting executive compensation levels, the Committee retained full discretion to consider or disregard data collected through benchmarking studies. In addition to the market data, compensation decisions also considered individual and Company performance, retention concerns, the importance of the position, internal equity and other factors.

Key Components of Our NEO Compensation Program

The key components of our executive compensation program are discussed below.

•Base Salary — provides sufficient competitive pay to attract and retain experienced and successful executives.

•Cash Bonus Incentive — encourages and rewards contributions to our annual corporate performance goals.

•Long Term Equity Incentives — encourages a multi-year focus on performance, rewards building long-term Fortis shareholder value and helps retain NEOs.

The other elements of our executive compensation program are discussed below under the heading “Other Components of Our Executive Compensation Program”, which summarizes the benefit programs that are available to our NEOs.

Base Salary

The Committee annually reviews and approves the base salaries, and any adjustments thereto, of the NEOs. In making these determinations, the Committee considers the executive’s job responsibilities, individual performance, leadership and years of experience, the performance of the Company, the recommendation of the CEO (except for the base salary of the CEO) and the target total direct compensation package as well as the benchmarking analysis conducted by its advisor.

The 2023 base salaries for the NEOs, including any year-over-year change, were:

NEO	2022 Base Salary		2023 Base Salary		Percent Increase
Linda H. Apsey	$	865,000	$	900,000	4.0	%
Gretchen L. Holloway	422,000		434,700		3.0	%
Brian Slocum	400,000		426,000		6.5	%
Christine Mason Soneral	409,800		418,000		2.0	%
Krista Tanner	370,900		389,400		5.0	%

Increases for Mr. Slocum and Ms. Tanner considered the market median data and each executive’s sustained performance.

Annual Corporate Performance Bonus

Early each year, the Committee approves our ACPB goals and targets, which are based on key Company objectives relating to operational excellence and superior financial performance. The corporate performance goals and targets were designed to align the interests of customers, the shareholder and management, and

87

encourage teamwork and coordination among all of our executives and employees with a common focus on the growth and success of the Company.

The ACPB goals were individually weighted. Weights were assigned to each goal based on areas of focus during the year and difficulty in achieving target performance. Weights were also assigned so that there was a balance between operational and financial goals. Each goal operated independently, and, for most goals, there was not a range of acceptable performance; if a goal was not achieved, there was no payout for that goal. Where performance goals were stated in a range, the threshold goals were generally expected to be achieved while the target goals were considered “stretch” goals with lower expectation of achievement. The bonus goals were designed to be challenging to meet, while remaining achievable.

For 2023, the ACPB consisted of four primary measurement categories: Financial, Safety & Compliance, Culture and System Performance. System Performance represented 60% of the target bonus opportunity, reflecting the inherent importance of driving operational performance, reliability and needed investment in our transmission system for the benefit of our customers.

Target levels for the corporate performance goals were determined based on our annual and long-term strategic plans, historical performance, expectations for future growth and desired improvement over time. Our safety, operations and security goals were established to deliver high performance in core company operations. Benchmarks and metrics were used in connection with these goals to establish a level of performance in the top decile or quartile within our industry. Likewise, our security goals led to the deployment of industry leading practices resulting in a generally enhanced security posture.

Corporate performance goal criteria approved by the Committee for 2023, the rationale for the target goal (in some cases in relation to the prior year target) and actual bonus results, were as set forth below.

Financial goals represented 20% of the total maximum annual bonus target and included specific measures for Non-Field Operation and Maintenance Expense and Net Income.

Category	Goal	Rationale for Goal	Rationale for Target Goal	Potential Payout		2023 Results		Actual Payout

____________________________

(1)We utilize adjusted net income as a criterion in measuring achievement of financial goals for our ACPB. This non-GAAP financial measure reconciles to net income of our Regulated Operating Subsidiaries as follows:

(In millions of USD)	2023
Net income of Regulated Operating Subsidiaries	$	592
Adjustments related to income taxes	(3)
Adjusted net income	$	589

Additionally, our executives, including the NEOs, are eligible for an executive bonus multiplier. To further motivate management to provide value to the shareholder, in 2023 we included a performance factor under which their ACPB payouts could be increased for outperformance by as much as 100% based on multiple measures, as follows:

Measure	Threshold	Maximum	Achievement	Multiplier	Weight	Result
Capital Project Plan	$892M	$999M	$906M	1.13x	40%	0.45x
Adjusted Consolidated Net Income (1)	$469M	$490M	$470M	1.05x	20%	0.21x
Strategic Plan Objectives	Achieve 3 Objectives	Achieve 6 Objectives	Achieved 2 Objectives	1.00x	30%	0.30x
Inclusion & Diversity Plan	Achieve 1 Goal	Achieve 2 Goals	Achieved 1 Goal	1.50x	10%	0.15x
Bonus Multiplier						1.11x

____________________________

(1)We utilize adjusted consolidated net income as a criterion in measuring achievement of financial goals for the executive bonus multiplier. This non-GAAP financial measure reconciles to consolidated net income of ITC Holdings as follows:

(In millions of USD)	2023
Net income	$	463
Adjustments related to income taxes	7
Adjusted consolidated net income	$	470

Each measure has an established scale, which includes a threshold level and below equating to a 1.00x multiplier, having no impact on the bonus award, to a maximum of 2.00x, which would increase the bonus by 100% to a maximum of 200% of target. Achievement against performance scales related to each of the above metrics produced an executive bonus multiplier of 1.11x. This performance factor was applied to the ACPB factor of 100% to produce a final payment of approximately 111% of target.

Bonuses are based on a target bonus, which for each executive is a percentage of his or her base salary. The Committee considers each individual’s job responsibilities and the results of its benchmarking analysis when determining the base bonus percentage for the executive officers, including the NEOs, which we refer to as the “target bonus levels.” Target bonus levels for 2023 were 100% of base salary for each NEO.

Long-Term Equity Incentive

The Committee provides and maintains a long-term equity incentive program under the Executive Omnibus Plan and the Fortis Inc. 2020 Restricted Share Unit Plan. In February 2023, the Committee approved grants of SBUs and PBUs to the NEOs, based on our CEO’s recommendation (except for grants to the CEO), and also on the Committee’s assessment of the performance of the Company and the executive. Award opportunities for the NEOs were provided in a mix of PBUs (weighted 67%) and SBUs (weighted 33%). The PBUs have a three-year performance period and can be earned between 0% and 200% for results in three separate measures, Total Shareholder Return (relative to Fortis’ peer group) weighted at 45%, ITC cumulative consolidated net income weighted at 45% and Fortis Carbon Reduction Performance weighted at 10%. The ultimate number of PBUs that can be earned is also subject to a Fortis performance diversity, equity and inclusion modifier (“DEI Modifier”) which consists of two targets that may modify the aggregate score of the three performance measures by up to +/- 2.5 percentage points for each DEI Modifier target objective (or a total of +/- 5.0

91

percentage points). As a result, if the three performance measures are each met at the maximum level of performance and the maximum DEI Modifier is applied, 205% of the target PBUs granted may be earned. These PBU metrics were selected because Total Shareholder Return aligns with the Fortis shareholder experience, cumulative consolidated net income measures our sustained growth (organic and development), cost management and efficiency and carbon reduction performance supports a corporate-wide goal of 75% reduction in Scope 1 emissions by 2035 and the DEI Modifier target supports Fortis’ corporate-wide diversity, equity and inclusion priorities. Each unit is generally equivalent to one share of Fortis stock (as traded on the Toronto Stock Exchange) and earned PBU units are payable in cash and earned SBU units are payable in cash or Fortis common stock. SBUs vest over the same three-year period based on the recipient’s continued service. Awards to the CEO were also presented to the Board of Directors by the Committee and ratified by the Board of Directors (other than the CEO). The amounts and more detailed terms of the 2023 SBU and PBU grants made under the Fortis Inc. 2020 Restricted Share Unit Plan and the Executive Omnibus Plan are described in the narrative following the Grants of Plan-Based Awards Table. The awards were designed to reward, motivate and encourage long-term performance, act as a retention mechanism and further align the interests of the NEOs with the interests of the Fortis shareholders. Total value for the award for each grantee was determined based on a percentage of salary. For the NEOs, when the 2023 awards were made, the award values were targeted to be:

NEO	Grant Value Percent of Salary
Ms. Apsey	250	%
Ms. Holloway	175	%
Mr. Slocum	140	%
Ms. Mason Soneral	175	%
Ms. Tanner	175	%

In determining the size of grants under the long-term incentive program and the award mix, the Committee considered market practice, the recommendation of the CEO (with respect to grants other than to the CEO) in light of comparisons to benchmarking data, expense to the Company and the practice of other U.S. Fortis subsidiary companies.

Other Components of Our Executive Compensation Program

Pension Benefits. As is common in our industry and as established pursuant to our initial formation requirements included in the acquisition agreement with DTE Energy for ITCTransmission, we maintain a tax-qualified defined benefit retirement plan for eligible employees, comprised of a traditional pension component and a cash balance component. All employees, including the NEOs, participate in either the traditional component or the cash balance component. We have also established a supplemental nonqualified, noncontributory retirement benefit plan for selected management employees: the Executive Supplemental Retirement Plan, or ESRP, in which all of the NEOs participate. This plan provides for benefits that supplement those provided by our qualified defined benefit retirement plan. Benefits payable to the NEOs pursuant to the retirement plans are set by the terms of those plans. The Committee exercises no regular discretionary authority in the determination of benefits. The retirement plans may be modified, amended or terminated at any time, although no such action may reduce a NEO’s earned benefits. See “Pension Benefits” for information regarding participation by the NEOs in our retirement plans as well as a description of the terms of the plans.

Benefits and Perquisites. The NEOs participate in a variety of benefit programs, which are designed to enable us to attract and retain our workforce in a competitive marketplace. These programs include our Savings and Investment Plan, which consists of an employee deferral contribution component and an employer safe-harbor matching contribution component.

Our NEOs are provided a limited number of perquisites in addition to benefits provided to our other employees. The purpose of these perquisites is to minimize distractions from the NEOs’ attention to important Company initiatives, to facilitate their access to work functions and personnel, and to encourage interactions among NEOs and others within professional, business and local communities. NEOs are provided perquisites such as auto allowance, financial, estate and legal planning, income tax return preparation, annual physical, club memberships, relocation expenses and personal liability insurance. Additionally, we own aircraft to facilitate the business travel schedules of our executives and other employees, particularly to locations that do not

provide efficient commercial flight schedules. Ms. Apsey and guests who travel with her are permitted to travel for personal business on our aircraft, with an annual maximum of 50 flight hours for such personal travel. Ms. Apsey incurs imputed income for all guests and herself for personal travel in the amount of the incremental cost to the Company of such travel.

We purchase tickets to various sporting, civic, cultural, charity and entertainment events. We use these tickets for business development, partnership building, charitable donations and community involvement. If not used for business purposes, we may make these tickets available to employees, including the NEOs, as a form of recognition and reward for their efforts. Because such tickets have already been purchased, we do not believe that there is any aggregate incremental cost to the Company if a NEO uses a ticket for personal purposes.

None of the NEOs are reimbursed for income taxes associated with the value of the perquisites. The Committee continues to monitor and review the Company’s perquisite program. Perquisites are further discussed in footnote 4 to the “Summary Compensation Table.”

Potential Severance Compensation. Pursuant to their employment agreements, each NEO is entitled to certain benefits and payments upon a termination of his or her employment. Benefits and payments to be provided vary based on the circumstances of the termination. We believe it is important to provide these protections in order to ensure our NEOs will remain engaged and committed to us during an acquisition of the Company or other transition in management. See “Employment Agreements and Potential Payments Upon Termination or Change in Control” for further detail on these employment agreements, including a discussion of the compensation to be provided upon termination or a change in control.

Clawback Policy

The Board has approved clawback provisions for certain compensation plans. These provisions allow the Board to require the forfeiture, recoupment or repayment of compensation if there is a restatement of financial results or fraud, gross negligence or intentional misconduct by one or more executives. The Board may also require a return of compensation in the event of a mistake or accounting error in the calculation of such compensation.

Stock Ownership Policy

The Board believes that having a share ownership policy is a key element of strong corporate governance and aligns the interests of management with the interests of Fortis shareholders. Under these guidelines, which became effective January 1, 2020, officers, including NEOs, must achieve and maintain the applicable level of Fortis stock ownership by the fifth anniversary of when the guidelines first became applicable to the individual. The current levels are as follows:

Position	Ownership Level
Chief Executive Officer	2x annual base salary
Executive and Senior Vice Presidents	1.5x annual base salary
Vice Presidents	1x annual base salary

The securities that qualify for the purpose of determining compliance with the policy are common shares of Fortis stock and the executive’s outstanding SBU awards. Share ownership levels include Fortis securities beneficially owned: (i) in a trust; (ii) by the executive’s spouse; and (iii) by the executive’s minor children. Any executive that fails to maintain minimum stock ownership under these guidelines will not be eligible for future equity-based compensation awards until the later of (i) the end of the one-year period commencing on the date of such failure or (ii) such time as the executive is again in compliance with the guidelines. As of December 31, 2023, each of the NEOs was in compliance with this policy.

(1)    The amounts reported in this column represent the grant date fair value of PBU awards and SBU awards granted to the NEOs under the Executive Omnibus Plan and the Fortis Inc. 2020 Restricted Share Unit Plan in accordance with FASB Accounting Standards Codification Topic 718, or ASC 718.

The grant date fair value of the SBU awards is based on the applicable share price on the grant date. The grant date fair value of the PBU awards is based on the applicable share price on the grant date and the payout of the performance based on probable outcome (which approximates target achievement), and market conditions. The SBU awards and PBU awards are liability awards, subject to remeasurement through the vesting date, and settled in cash, see “Grants of Plan-Based Awards.” The value of the 2023

94

PBU awards at the grant date assuming that the highest level of performance conditions will be achieved are as follows:

Ms. Apsey	$	3,074,940
Ms. Holloway	1,039,676
Mr. Slocum	815,098
Ms. Mason Soneral	999,724
Ms. Tanner	931,316

(2)    The amounts reported in this column include cash awards tied to the achievement of annual Company performance goals under our ACPB in effect for each of 2023, 2022 and 2021. For information regarding the corporate goals for 2023, see “Compensation Discussion and Analysis - Key Components of Our NEO Compensation Program - Annual Corporate Performance Bonus."

(3)    All amounts reported in this column pertain to the tax-qualified defined benefit pension plan and the supplemental nonqualified, noncontributory retirement plan maintained by the Company. None of the income on nonqualified deferred compensation was above-market or preferential. Variations in the amounts from year to year reflect an additional year of service and pay changes used in the accrued benefit, as well as changes in assumptions on which the benefits are calculated, for which the formula has not been materially revised. The discount rate used for the present value of accumulated benefits was 3.01% in 2021, 5.57% for 2022 and 5.24% for 2023. Due to the 256 basis point increase in discount rates during 2022, the change in present value declined from December 31, 2021 to December 31, 2022 and therefore 2022 reported change in pension values are zero. As of December 31, 2023, the cash balance interest crediting rate assumption changed from 3.55% for 2023 and 4.00% in all future years to 4.47% in 2024 and 4.50% in all future years.

(4)    All Other Compensation includes amounts for auto allowance, financial, estate and legal planning, income tax return preparation, annual physical, club memberships, event tickets, relocation expenses, personal liability insurance, personal use of company aircraft and for other benefits such as Company contributions on behalf of the NEOs pursuant to the matching component of the Savings and Investment Plan. Perquisites have been valued for purposes of these tables on the basis of the aggregate incremental cost to the Company. The incremental cost of the personal use of the Company aircraft was determined based upon the Company’s expenses incurred in connection with the actual costs of maintenance, landing, parking, crew and catering and estimated fuel costs relating to Ms. Apsey’s hours of use of the aircraft. Fuel expense was determined by calculating the average fuel cost for the month and the average amount of fuel used per hour. These benefits and perquisites for 2023, 2022 and 2021 are itemized in the table below as required by applicable SEC rules.

____________________________

(1)    The amount shown in Column (d) represents the potential payout for the ACPB based on “target bonus levels.” The amount payable assuming maximum achievement of all bonus goals, including the bonus multiplier, is set forth in column (e). Actual dollar amounts paid are disclosed and reported in the “Summary Compensation Table” as Non-Equity Incentive Plan Compensation. For more information regarding the ACPBs, see “Compensation Discussion and Analysis — Key Components of Our NEO Compensation Program — Annual Corporate Performance Bonus.”

(2)    Payment of each PBU award is contingent on meeting performance targets based on (1) Fortis Total Shareholder Return in comparison to the Total Shareholder Return during the performance period for each of the companies that comprise the 2023 Fortis peer group, (2) cumulative consolidated net income for each fiscal year during the performance period and (3) Fortis’ carbon reduction performance during the performance period. The performance measures are independent of each other. If threshold, target or maximum performance goals are attained in the performance period, 50%, 100% or 200% of the target amount, respectively, may be earned. If actual performance falls between threshold, target and maximum, the awards would be prorated between levels based on performance outcome. In addition, a DEI Modifier which consists of two performance objectives, may modify the aggregate score of the three performance measures by up to +/- 2.5 percentage points for each DEI Modifier target objective (or a total of +/- 5.0 percentage points). The DEI Modifier is based on increases in the representation of (1) women in executives roles and (2) black, Indigenous peoples and minority community members in executive roles across all Fortis entities. If the three performance measures are each met at the maximum level of performance and the maximum DEI Modifier is applied, 205% of the target PBUs granted may be earned, which amount is set forth in the “Maximum” column above. For more information regarding performance share awards, see “Grant of Plan-Based Awards - Performance-Based Unit Award Agreements.”

(3)    Grant Date Fair Value consists of SBUs and PBUs awarded under the Fortis Inc. 2020 Restricted Share Unit Plan and Executive Omnibus Plan, respectively, with a grant date of January 1, 2023. The SBUs and

96

PBUs reflected here are recorded at fair value at the date of grant, which was $40.35 per share. Share fair values were converted from Canadian Dollars to US Dollars using the “Applicable Exchange Rate” defined in the plans.

The Committee has established long-term incentive targets as a percentage of the base salary for each NEO in consideration of benchmarking data on total direct compensation, the importance of the NEO’s position to the success of the Company, our need to create meaningful incentives to enhance performance and the culture of teamwork that makes our company successful. The Committee did not have a pre-established targeted allocation of total direct compensation.

The Committee had the power to award SBUs in the form of equity or cash under the Fortis Inc. 2020 Restricted Share Unit Plan and PBUs in the form of equity or cash under the Executive Omnibus Plan with the terms of each award set forth in a written agreement with the recipient. Grants made in 2023 to the NEOs were made under their respective plans pursuant to terms stated in the SBU and PBU award agreements.

Performance-Based Unit Award Agreements

The PBU award agreements entered into with each NEO on January 1, 2023 (the “PBU Grant Date”) (each a “PBU Agreement”) provide generally that the award will vest on January 1, 2026 (the “PBU Vesting Date”) to the extent one or more of the performance goals are met and if the grantee continues to be employed by the Company through the PBU Vesting Date. 45% of the Target Number of PBUs shall be related to the Fortis Total Shareholder Return goal (the “TSR goal”), 45% of the Target Number of PBUs shall be related to the Cumulative Consolidated Net Income goal (the “CCNI goal”) and 10% of the Target Number of PBUs shall be related to the Fortis Carbon Reduction Performance goal (the “CRP goal”). In addition, the percentage of the Target Number of PBUs actually paid may be adjusted up or down based on Fortis’ performance against the DEI Modifier targets. The PBUs will become earned as set forth in the following tables:

Measurement Category	Goal at Threshold	Shares at Threshold	Goal at Target	Shares at Target	Goal at Maximum	Shares at Maximum
Fortis Total Shareholder Return	30th percentile	50% of TSR Target Units	50th percentile	100% of TSR Target Units	85th percentile	200% of TSR Target Units
Cumulative Consolidated Net Income	98% of Target	50% of CCNI Target Units	100% of Target	100% of CCNI Target Units	104% of Target	200% of CCNI Target Units
Fortis Carbon Reduction Performance	8.8M tonnes	50% of CRP Target Units	7.9M tonnes	100% of CRP Target Units	7.1M tonnes	200% of CRP Target Units

Gender Executive Representation Performance			Ethnic Executive Representation Performance
Achievement	Payout % Adjustment		Achievement	Payout % Adjustment
Less than a 5% increase	-2.5%	Minimum	Less than a 5% increase	-2.5%	Minimum
5% to 9.9% increase	0%		5% to 9.9% increase	0%
Greater than or equal to a 10% increase	+2.5%	Maximum	Greater than or equal to a 10% increase	+2.5%	Maximum

The performance period for the award is January 1, 2023 through December 31, 2025 (the “Payment Criteria Period”). The performance measures are independent of each other; that is, if the threshold level of one performance measure is attained, units relating to that measure will be “earned” (subject to vesting as otherwise provided in the PBU Agreement) even if the threshold level of the other performance measure is not attained. The number of PBUs that are “earned” with respect to each performance measure will be prorated between levels based on performance. The Committee will have discretion to reduce the number of PBUs earned under certain circumstances.

Total Shareholder Return of Fortis will be compared to each of the companies (the “Peer Companies”) listed in the Fortis Peer Group 2023 Report excluding any company that is no longer traded on the Toronto Stock

97

Exchange or a “national securities exchange” at the end of the Payment Criteria Period. The Peer Companies currently consist of the following 25 U.S. and Canadian public utility companies:

Alliant Energy Corporation	Emera Incorporated	PG&E Corporation
Ameren Corporation	Entergy Corporation	Pinnacle West Capital Corporation
Atmos Energy Corporation	Evergy, Inc.	PPL Corporation
Canadian Utilities Limited	Eversource Energy	Public Service Enterprise Group Inc.
CenterPoint Energy Inc.	FirstEnergy Corp.	Sempra Energy
CMS Energy Corporation	Hydro One Limited	UGI Corporation
Consolidated Edison Inc.	NiSource Inc.	WEC Energy Group, Inc.
DTE Energy Company	OGE Energy Corp.	Xcel Energy Inc.
Edison International

The Total Shareholder Return of Fortis and the Peer Companies shall be computed in U.S. dollars as follows:

A: Calculate the Market Price as of the first day of the Payment Criteria Period (if necessary, converted into U.S. dollars based on the Applicable Exchange Rate as defined in the Executive Omnibus Plan)

B: Calculate the Market Price as of the last day of the Payment Criteria Period (if necessary, converted into U.S. dollars based on the Applicable Exchange Rate)

C: Calculate the total dividends paid per share of its common stock (or equivalent security) during the Payment Criteria Period (if necessary, converted into U.S. dollars based on the Applicable Exchange Rate)

Total Shareholder Return = ((B - A) + C)/A, where Market Price is the 5-day volume weighted average price of Fortis stock and the Payment Criteria Period is the 3-year performance period.

Adjusted Consolidated Net Income for the Company for each calendar year in the Payment Criteria Period shall be equal to net income as set forth in the Company’s audited consolidated financial statements contained in its annual report on Form 10-K for such year, as adjusted for extraordinary items and changes in Return on Equity, in each case at the Committee’s discretion. Cumulative Consolidated Net Income for the Company during the Payment Criteria Period shall be the sum of the Adjusted Consolidated Net Income for each of the three years in the Payment Criteria Period. See “Compensation Discussion and Analysis - Key Components of Our NEO Compensation Program - Annual Corporate Performance Bonus" for a reconciliation of Adjusted Consolidated Net Income to Net Income.

If the grantee ceases to be employed before the PBU Vesting Date due to death, disability or “Retirement” (as defined below), and, in each case, the grantee has been employed with the Company for 15 years or more, the grantee will receive, following the PBU Vesting Date, the number of PBUs to which the grantee would have otherwise been entitled if the grantee had remained employed through the PBU Vesting Date. If the grantee ceases to be employed before the PBU Vesting Date due to death, disability or Retirement, and the grantee has been employed with the Company for less than 15 years, the grantee will receive, following the PBU Vesting Date, a prorated number of PBUs reflecting the actual period between the PBU Grant Date and the grantee’s termination date. If the grantee ceases to be employed before the PBU Vesting Date due to involuntary termination without cause, the grantee will receive, following the PBU Vesting Date, a prorated number of PBUs reflecting the actual period between the PBU Grant Date and the grantee’s termination date, and grantee is not entitled “dividend equivalents” earned on the PBUs following the grantee’s termination date. If termination occurs prior to the PBU Vesting Date other than as a result of death, disability, Retirement, or involuntary termination without cause, grantee will forfeit the award.

“Retirement” is defined to mean termination of grantee’s employment with the Company on or after achieving at least age 55 and ten (10) years of service. Payout in respect of such termination requires that the grantee has provided the Company with at least ninety days’ written notice of such retirement.

Upon a “Change of Control,” as defined in the Executive Omnibus Plan, the Governance and Human Resources Committee may provide for appropriate settlements of the outstanding PBUs or for the continuing entity or successor to assume the outstanding PBUs by providing replacement awards (“Replacement Awards”), that are substantially equivalent to the terms of the PBUs held prior to the Change in Control, on the effective date of the consummation of the event resulting in the Change of Control (the “Change of Control Redemption Date”). The Replacement Awards must be substantially equivalent to the value and terms of the PBUs held prior

98

to the Change of Control and must include conditions that provide for vesting and payout if there is an involuntary employment action that occurs within 24 months following the Change of Control. In the event of a Change of Control and an involuntary employment action that occurs within 24 months following a Change of Control, the payout percentage for the Replacement Awards should be calculated as the greater of (i) target level performance and (ii) the actual performance level achieved had the Payment Criteria Period ended on the involuntary employment action date. In the event of a Change of Control and the PBUs are settled and not substituted with Replacement Awards, the payout percentage for outstanding PBUs is the product of (i) the higher of (A) 100% of the target number of PBUs in the award or (B) the actual payout percentage based on the Committee’s assessment of performance of the payment criteria from the beginning of the Payment Criteria Period for the award through the date of the Change of Control, multiplied by (ii) a fraction, the numerator of which is the number of days elapsed in the Payment Criteria Period for the award through the date on which the Change of Control occurred and the denominator of which is the total number of days in the payment criteria period for the award.

Grantees are entitled to receive additional PBUs equal to the “dividend equivalent” when a cash dividend is paid on common shares of Fortis stock (each a “Common Share”). Such “dividend equivalent” shall be equal to a fraction where the numerator is the product of (a) the number of PBUs in the grantee’s account on the date that the dividends are paid, including PBUs previously credited as “dividend equivalents,” multiplied by (b) the dividend paid per Common Share and the denominator of which is the “Market Price” of one Common Share calculated on the date that dividends are paid, converted to U.S. dollars based on the Applicable Exchange Rate. All “dividend equivalent” PBUs shall have a PBU Vesting Date which is the same as the PBU Vesting Date for the PBUs in respect of which such additional PBUs are credited.

Service-Based Unit Award Agreements

The SBU award agreements entered into with each NEO on January 1, 2023 (the “SBU Grant Date”) (each a “SBU Agreement”) provide generally that, so long as the grantee remains employed by the Company, the SBUs fully vest on January 1, 2026 (the “SBU Vesting Date”). However, if the grantee ceases to be employed before the SBU Vesting Date due to death, disability or Retirement, and, in each case, the grantee has been employed with the Company for 15 years or more, the grantee will receive, the number of SBUs to which the grantee would have otherwise been entitled if the grantee had remained employed through the SBU Vesting Date, with, in the case of the grantee’s death or disability, the SBUs being settled upon the date of the grantee’s termination of employment and, in the case of the grantee’s Retirement, the SBUs being settled on the SBU Vesting Date. If the grantee ceases to be employed before the SBU Vesting Date due to death, disability or Retirement, and, in each case, the grantee has been employed with the Company for less than 15 years, the grantee will receive a prorated number of SBUs to reflect the actual period between the SBU Grant Date and the date of the grantee’s death, disability or Retirement, with, in the case of the grantee’s death or disability, the SBUs being settled upon the date of the grantee’s termination of employment and, in the case of the grantee’s Retirement, the SBUs being settled on the SBU Vesting Date. If the grantee ceases to be employed before the SBU Vesting Date due to involuntary termination without cause, the grantee will receive, following the SBU Vesting Date, a prorated number of SBUs reflecting the actual period between the SBU Grant Date and the grantee’s termination date, and grantee is not entitled “dividend equivalents” earned on the SBU shares following the grantee’s termination date. If termination occurs prior to the SBU Vesting Date other than as a result of death, disability, Retirement or involuntary termination without cause, the grantee will forfeit the award.

“Retirement” is defined in the same manner as defined in the description of the PBU Agreement disclosed above.

Upon a “Change of Control,” as defined in the Fortis Inc. 2020 Restricted Share Unit Plan, the Fortis Human Resources Committee may provide for appropriate settlements of the outstanding SBUs or for the continuing entity or successor to assume the outstanding SBUs by providing Replacement Awards that are substantially equivalent to the terms of the SBUs held prior to the Change in Control, on the effective date of the consummation of the event resulting in the Change of Control. The Replacement Awards must be substantially equivalent to the value and terms of the SBUs held prior to the Change of Control and must include conditions that provide for vesting and payout if there is an involuntary employment action that occurs within 24 months following the Change of Control. In the event of a Change of Control and an involuntary employment action that occurs within 24 months following a Change of Control, the Replacement Awards should payout no later than 10 business days following the involuntary employment action date. In the event of a Change of Control and the

99

SBUs are settled and not substituted with Replacement Awards, the SBU shares become vested and payout on the date of the Change of Control based on the market price as of the date immediately prior to the Change of Control.

Grantees are entitled to receive additional SBUs equal to the “dividend equivalent” when a cash dividend is paid on common shares of Fortis stock (each a “Common Share”). Such “dividend equivalent” shall be equal to a fraction where the numerator is the product of (a) the number of unvested SBUs in the grantee’s account on the date that the dividends are paid, including SBUs previously credited as “dividend equivalents,” multiplied by (b) the dividend paid per Common Share and the denominator of which is the “Market Price” of one Common Share calculated on the date that dividends are paid, converted to U.S. dollars based on the Applicable Exchange Rate. All “dividend equivalent” SBUs shall have a SBU Vesting Date which is the same as the SBU Vesting Date for the SBUs in respect of which such additional SBUs are credited.

The SBU Agreement provides that the grantee may elect to have their SBU awards vest as common shares of Fortis Inc. stock or cash payment. If the grantee does not satisfy their share holding requirement stated in the Stock Ownership Policy, 50% of the SBU awards must settle in common shares of Fortis Inc. stock.

____________________________

(1)    Credited service is estimated as of December 31, 2023 and represents the service reflected in the determination of benefits. For determining vesting, service with DTE Energy is counted for the Qualified Plan only.

For Ms. Apsey, the credited service for the cash balance component of the Qualified Plan, includes service with DTE Energy. The Company began operations on February 28, 2003, following its acquisition of ITCTransmission from DTE Energy. As of that date, the benefits from DTE Energy’s qualified plan that had accrued, as well as the associated assets from DTE Energy’s pension trust, were transferred to the Qualified Plan. Therefore, even though DTE Energy service is included in determining the benefits under the cash balance component of the Qualified Plan, the benefits associated with this additional service do not represent a benefit augmentation, but rather a transfer of benefit liability and associated assets from DTE Energy’s qualified plan to the Qualified Plan. With respect to the ESRP, credited service includes Company service only for the period during which the NEO was an ESRP participant.

(2)    The “Present Value of Accumulated Benefit” is the estimated lump-sum equivalent value measured as of December 31, 2023 (the “measurement date” used for financial accounting purposes) of the benefit that was earned as of that date. Certain benefits are payable as an annuity only, not as a lump sum, and/or may not be payable for several years in the future. The values reflected are based on several assumptions. The date at which the present values were estimated was December 31, 2023. The rate at which future expected benefit payments were discounted in calculating present values was 5.24%, the same rate used for fiscal year-end 2023 financial accounting disclosure of the Qualified Plan. The future annual earnings rate on account balances under the cash balance and ESRP shift components of the Qualified Plan, and for ESRP benefits, was assumed to be 4.47% for 2024 and 4.50% thereafter.

102

We assumed no NEOs would die or become disabled prior to retirement or terminate employment with us prior to becoming eligible for benefits unreduced for early retirement. The assumed retirement age for each executive was generally the earliest age at which benefits unreduced for early retirement were available under the respective plans. For consistency, we generally use the same assumed retirement commencement age for other benefits, including benefits expressed as an account value where the concept of benefit reductions for early retirement is not meaningful. The assumed retirement benefit commencement ages were 58 for each NEO.

Post-retirement mortality was assumed to be in accordance with the Pri-2012 mortality table projected for future mortality improvements with MP-2020 generational scale. For all other benefits, payment was assumed to be as a single lump sum, although other actuarially equivalent forms are available.

We maintain one tax-qualified noncontributory defined benefit pension plan and one supplemental nonqualified, noncontributory defined benefit retirement plan. First, we maintain the Qualified Plan, which provides funded, tax-qualified benefits up to the limits on compensation and benefits under the Internal Revenue Code. Generally, all of our salaried employees, including the NEOs, are eligible to participate.

We maintain the ESRP, in which all of our NEOs participate. The ESRP provides additional retirement benefits which are not tax qualified.

The following describes the cash balance component of the Qualified Plan and the ESRP, and pension benefits provided to the NEOs under those plans.

Cash Balance Qualified Plan

Benefits under the Qualified Plan are funded by an irrevocable tax-exempt trust. A NEO’s benefit under the Qualified Plan is payable from the assets held by the tax-exempt trust.

NEOs become fully vested in their normal retirement benefits described below with 3 years of service, including service with DTE Energy, or upon attainment of the plan’s normal retirement age of 65. If a NEO terminates employment with less than 3 years of service, the NEO is not vested in any portion of his or her benefit.

Mses. Apsey, Holloway, Mason Soneral and Tanner and Mr. Slocum participate in the Cash Balance Qualified Plan. The benefits are stated as a notional account value.

Each year, a NEO’s account is increased by a “contribution credit” equal to 7% of pay. For this purpose, pay is equal to base salary plus bonuses and overtime up to the compensation limit of the Qualified Plan ($330,000 in 2023). Each year, a NEO’s account is also increased by an “interest credit” based on 30-year Treasury rates.

Upon termination of employment, a vested NEO may elect full payment of his or her account. Alternate forms of benefit (e.g., various forms of annuities) are available as well that have the same actuarial value as the account.

Mses. Apsey, Holloway, Mason Soneral and Tanner and Mr. Slocum are entitled to immediate payment of their account value on termination of employment, even if before normal retirement age. Ms. Apsey’s estimated account value as of year-end 2023 is approximately $538,000, Ms. Holloway’s is approximately $378,000, Mr. Slocum’s is approximately $383,000, Ms. Mason Soneral’s is approximately $377,000, Ms. Tanner’s is approximately $198,000.

The ESRP provides notional account accruals similar to the cash balance component of the Qualified Plan. The “compensation credit” to the NEO’s notional account, analogous to the contribution credit in the cash balance component of the Qualified Plan, is equal to 9% of base salary plus actual bonus earned under the Company’s ACPB plan. The “investment credit,” analogous to the interest credit in the cash balance component of the Qualified Plan, is similarly based on 30-year Treasury rates.

The ESRP shift benefit is an amount that would otherwise be payable from the ESRP, but is instead being paid from the Qualified Plan, subject to applicable qualified plan legal limits on the ability to discriminate in favor of highly paid employees. The NEO’s cash balance account is increased by any amounts shifted from the ESRP. The purpose of the benefit is to provide the NEO and the Company the tax advantages of providing benefits through a tax qualified plan.

103

Ms. Apsey has received ESRP shift additions to her Qualified Plan cash balance account. There was no shift of compensation credits for 2023, although previous shifts have continued to earn interest credits. As of year-end 2023, her ESRP shift balance was approximately $40,000.

Executive Supplemental Retirement Plan

The ESRP is a nonqualified retirement plan. Only selected executives participate, including all our NEOs. The purpose of the ESRP is to promote the success of the Company and its subsidiaries by providing the ability to attract and retain talented executives by providing such designated executives with additional retirement benefits.

The ESRP resembles the cash balance component of the Qualified Plan in that benefits are expressed as a notional account value and the vested account balance is payable as a lump sum on termination of employment, although an installment option of equivalent value is also available.

Each year, a NEO’s account is increased by a “compensation credit” equal to 9% of pay. For this purpose, pay is equal to base salary plus any bonus under the Company’s ACPB plan. There is no limit on compensation that may be taken into account as in the Qualified Plan. Each year, a NEO’s account is also increased by an “investment credit” equal to the same earnings rate as the interest credit in the cash balance component of the Qualified Plan, based on 30-year Treasury rates.

The plan has been in effect since March 1, 2003. Vesting occurs at 20% for each year of participation. All of our NEOs are fully vested.

As noted above in the description of the Qualified Plan, a portion of the ESRP account balance may be shifted to the cash balance component of the Qualified Plan each year, as permitted under the rules for qualified plans. Such a shift allows the NEOs to become immediately vested in the account values shifted and confers certain tax advantages to the NEOs and us. As of December 31, 2023, the ESRP account values, net of the amounts shifted to the Qualified Plan, are as follows:

Ms. Apsey	$	2,751,725
Ms. Holloway	691,924
Mr. Slocum	574,354
Ms. Mason Soneral	1,088,708
Ms. Tanner	525,199

The ESRP is funded with a Rabbi Trust, which we cannot use for any purpose other than to satisfy the benefit obligations under the ESRP, except in the event of the Company’s bankruptcy, in which case the assets are available to general creditors.

Nonqualified Deferred Compensation

We maintain the Executive Deferred Compensation Plan under which nonqualified deferred compensation is permissible. Selected officers of the Company, including the NEOs, are eligible to participate in this plan. NEOs are allowed to defer up to 75% of their salary and 100% of their bonus, and deferral elections may change annually. Investment earnings are based on the various investment options available under the plan and are selected by the individual NEOs (which selections NEOs may change at any time). Distributions will generally be made at the NEO’s termination of employment for any reason. Mr. Slocum elected to participate in 2022 and his deferral was withheld in 2023. Mr. Slocum elected to defer 40% of his bonus and his deferral was made in 2023 due to his 2022 bonus payment occurring in 2023. The following table reports amounts contributed in 2023, together with aggregate earnings on contributions and withdrawals or distributions on contributions in

104

2023, under the plan. For the year ended December 31, 2023, the investment options available under the plan generated annual returns ranging from 4.22% to 46.02%.

Employment Agreements and Potential Payments Upon Termination or Change in Control

Employment Agreements

As referenced above, we entered into an employment agreement with Ms. Apsey in December 2012 which superseded the employment agreement then in effect. In February 2015, we entered into an employment agreement with Ms. Mason Soneral which superseded her employment agreement then in effect. In July 2017, we entered into an employment agreement with Ms. Holloway, which superseded her employment agreement then in effect. In February 2019, we entered into an employment agreement with Ms. Tanner which superseded her employment agreement then in effect. In February 2022, we entered into an employment agreement with Mr. Slocum which superseded his employment agreement then in effect. Each employment agreement is subject to automatic one-year employment term renewals each year beginning on its second anniversary, unless either party provides the other with 30 days’ advance written notice of intent not to renew the employment term. Ms. Apsey’s agreement was modified in October 2016 in connection with her appointment as President and Chief Executive Officer and the initial term of the agreement expired on December 31, 2018 but is subject to the automatic one-year renewal provision described above. The following describes the material terms of the employment agreements, as amended, with the NEOs who remained employed by the Company on December 31, 2023.

The employment agreements provide that each NEO will receive an annual base salary equal to their current base salary, which is subject to annual review and increase by our Board of Directors at its discretion. The employment agreements also provide that NEOs are eligible to receive an annual cash bonus, subject to our achievement of certain performance targets established by our Board of Directors, as detailed in “Compensation Discussion and Analysis.” The employment agreements also provide the NEOs with the right to participate in equity plans, employee benefit plans and retirement plans, including but not limited to welfare plans, retiree welfare benefit plans and defined benefit and defined contribution plans.

In addition, the NEOs’ employment agreements provide for payments by us of certain benefits upon termination of employment. The rights available at termination depend on the situation and circumstances surrounding the terminating event. The terms “Cause” and “Good Reason” are used in the employment agreements of each NEO and an understanding of these terms is necessary to determine the appropriate rights for which a NEO is eligible. The terms are defined as follows:

•Cause means: a NEO’s continued failure to substantially perform his or her duties (other than as a result of total or partial incapacity due to physical or mental illness) for a period of 10 days following written notice by the Company to the NEO of such failure; dishonesty in the performance of the NEO’s duties; a NEO’s conviction of, or plea of nolo contender to, a crime constituting a felony or misdemeanor involving moral turpitude; willful malfeasance or willful misconduct in connection with a NEO’s duties; any act or omission which is injurious to the financial condition or business reputation of the Company; or violation of the non-compete or confidentiality provisions of the employment agreement.

•Good reason means: a greater than 10% reduction in the total value of the NEO’s base salary, target bonus, and employee benefits; or if the NEO’s responsibilities and authority are substantially diminished.

If a NEO’s employment is terminated with cause by the Company or by the NEO without good reason, the NEO will generally only receive his or her accrued but unpaid compensation and benefits as of the date of his or

105

her employment termination. If the NEO terminates due to death or disability (as defined in the employment agreements), the NEO (or the NEO’s spouse or estate) would also receive a pro rata portion of his or her current year annual target bonus.

If a NEO’s employment is terminated by the Company without cause or by the NEO for good reason, the NEO will receive the following, subject to the NEO’s execution of a release agreement and commencing generally on the earliest date that is permitted under Section 409A of the Internal Revenue Code:

•any accrued but unpaid compensation and benefits including:

◦Ms. Apsey: cash balance and ESRP shift under the Qualified Plan and vested portion of ESRP balance; and

◦Ms. Holloway, Mr. Slocum, Ms. Mason Soneral and Ms. Tanner: cash balance under the Qualified Plan and vested portion of ESRP balance

•continued payment of the NEO’s then-current base salary for two years;

•if the termination is within six months before or two years after a “Change of Control” (as defined in the employment agreements), payment of an amount equal to two times the average of the ACPBs, that were payable to the NEO for the three fiscal years immediately preceding the fiscal year in which his or her employment terminates, payable in equal installments over the period in which continued base salary payments are made;

•a pro rata portion of the ACPB for the year of termination, based upon the Company’s actual achievement of the performance targets for such year as determined under the ACPB plan and paid at the time that such bonus would normally be paid;

•eligibility to continue coverage under our active medical, dental and vision plans subject to applicable COBRA rules; if such coverage is elected, we will reimburse the NEO for the shorter of 18 months, or until the NEO becomes eligible for coverage under another employer-sponsored group plan, in an amount equal to our periodic cost of such coverage for other executives, plus a tax gross-up amount;

•outplacement services for up to two years; and

•for Ms. Apsey, deemed satisfaction of the eligibility requirements of our Postretirement Welfare Plan for purposes of participation therein. In addition, if we terminate our Postretirement Welfare Plan and, by application of the provisions described in the prior sentence, any of these NEOs would otherwise be entitled to retiree welfare benefits, we will establish other coverage for the NEO or the NEO will receive a cash payment equal to our cost of providing such benefits, in order to assist the NEO in obtaining other retiree welfare benefits.

In addition, while employed by us and for a period of two years after any termination of employment without cause by the Company (other than due to their disability) or for good reason by them and for a period of one year following any other termination of their employment, the NEOs will be subject to certain covenants not to compete with or assist other entities in competing with our business and not to encourage our employees to terminate their employment with us. At all times while employed and thereafter, all of the NEOs will also be subject to a covenant not to disclose confidential information.

In the event the NEO becomes subject to excise taxes under Section 4999 of the Internal Revenue Code as a result of payments and benefits received under the employment agreements or any other plan, arrangement or agreement with us, we will pay the NEO only that portion of such payments which are in total equal to one dollar less than the amount that would subject the NEO to the excise tax.

106

____________________________

(1)All scenarios include the value of severance. For Ms. Apsey, the value of the Postretirement Welfare Plan is additionally included where applicable. The Pension Benefits Table assumes that none of the NEOs are terminated prior to retirement age and that benefits are paid once retirement commences (age 58 is assumed). All other accrued pension benefits have not been included in these termination scenarios but can be found in the “Pension Benefits Table.” The Nonqualified Deferred Compensation has also not been included in these termination scenarios but can be found in the “Nonqualified Deferred Compensation” section.

(2)Upon any termination of employment, benefits that are accrued but unpaid prior to that event are paid. These benefits are assumed to be $0 in the above tables.

(3)Change in control values include severance amounts reflecting cutbacks to the extent employer payments exceed the executive respective limits. Mr. Slocum would be subject to an excise tax on the employer payments as of the assumed change in control date; therefore, cutbacks in the amount of $82,080 (Mr. Slocum) have been reflected.

(4)In the event of termination for death (pre-retirement), the Qualified Plan benefits of Mses. Apsey, Holloway, Mason Soneral and Tanner and Mr. Slocum are payable immediately to the surviving spouse or designated beneficiary if not married and ESRP benefits are payable to a designated beneficiary.

(5)Under the Fortis Inc. 2020 Restricted Share Unit Plan, outstanding and unvested SBUs and respective dividend equivalents shall be deemed to be vested SBUs and redeemable on the date that is immediately prior to the effective date of the consummation of the transaction resulting from the Change of Control if the holder is not granted a Replacement Award. In the case of Death, Disability or, for SBUs granted prior to 2023, Retirement termination and, in each case, 15 years or more of service with the Company or its Affiliates, the outstanding and unvested SBU awards and respective dividend equivalents shall be deemed vested and redeemable on the date of the death or on the date on which the grantee’s service is terminated due to Disability or Retirement. In the case of Death, Disability or, for SBUs granted prior to 2023, Retirement termination and less than 15 years of service with the Company or its Affiliates, the outstanding and unvested SBU awards and respective dividend equivalents shall be deemed to have vested pro-rata based on the period served from grant date to termination and redeemable on the date of the death or on the date on which the grantee’s service is terminated due to Disability or Retirement. For the 2023 SBUs, in the case of Retirement termination, outstanding and unvested SBU awards and respective dividend equivalents will remain outstanding and shall vest on the SBU Vesting Date, with the number of SBUs that

109

vest on the SBU Vesting Date pro-rated to reflect the period of service from grant date to termination if the NEO has less than 15 years of service with the Company or its Affiliates. For the 2023 SBU awards, in the case of Involuntary Without Cause termination, the outstanding and unvested SBU awards and respective dividend equivalents shall be deemed to have vested pro-rata based on the period served from grant date to termination and redeemable on the SBU Vesting Date. In the case of Cause, Voluntary Termination and, for SBU awards granted prior to 2023, Involuntary Termination Without Cause, outstanding and unvested SBU awards and respective dividend equivalents shall be deemed to be forfeited.

(6)Under the Executive Omnibus Plan, outstanding and unvested PBU awards and respective dividend equivalents shall become redeemable on the Change of Control Redemption Date under a Change in Control (as defined in the Executive Omnibus Plan) if the holder is not granted a Replacement Award. In the case of Death, Disability or Retirement termination and, in each case, 15 years or more of service with the Company or its Affiliates, the outstanding and unvested PBU awards and respective dividend equivalents will remain outstanding and be payable on the payout date of such awards subject to the achievement of the applicable payment criteria. In the case of Death, Disability or Retirement termination and, in each case, less than 15 years of service with the Company or its Affiliates, the outstanding and unvested PBU awards and respective dividend equivalents shall be deemed to have vested pro-rata based on (a) for PBU awards granted prior to 2023, the anniversary date of the grant, and the grantee will receive, (i) one-third of the number of PBUs to which the grantee would have otherwise been entitled if the grantee had remained an employee through the PBU Vesting Date shall be deemed to have vested on the PBU Vesting Date if termination occurred on or after the one-year anniversary of the PBU Grant Date and before the two-year anniversary of the PBU Grant Date, and (ii) two-thirds of the number of PBUs to which the grantee would have otherwise been entitled if the grantee had remained an employee through the PBU Vesting Date shall be deemed to have vested on the PBU Vesting Date if termination occurred on or after the two-year anniversary of the PBU Grant Date but before the PBU Vesting Date and (b) for PBU awards granted in 2023 the period served from grant date to termination and redeemable on the PBU Vesting Date. For the 2023 PBU awards, in the case of Involuntary Without Cause termination, the outstanding and unvested PBU awards and respective dividend equivalents shall be deemed to have vested pro-rata based on the period served from grant date to termination and redeemable on the PBU Vesting Date. Values shown in the tables above are based on target performance for the 2022 and 2023 awards as an estimate of potential payments and actual performance of 147% for the 2021 awards. In the case of Cause, Voluntary Termination and, for PBU awards granted prior to 2023, Involuntary Termination Without Cause outstanding and unvested PBU awards and respective dividend equivalents shall be deemed to be forfeited.

(7)The value of the Postretirement Welfare Plan benefit is included in involuntary termination not for cause and change in control scenarios for Ms. Apsey since her employment agreement includes a provision for deemed satisfaction of the eligibility requirements when terminated under these scenarios. Postretirement Welfare Benefits is assumed to commence at age 58. The rate at which future expected benefit payments were discounted in calculating the Postretirement Welfare Plan present values was 5.30%, the same rate used for fiscal year-end 2023 accounting disclosure of the Postretirement Welfare Plan.

Upon death or disability, a NEO (or his or her estate) receives a pro rata portion of his or her current year target corporate performance bonus. All balances under the cash balance and ESRP shift components of the Qualified Plan, and the ESRP balance (vested portion only for disability), are immediately payable. If the NEO has 10 years of service after age 45, then the NEO (and his or her spouse) is eligible for retiree medical benefits.

Pay Ratio

As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act, and the SEC under Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of Linda H. Apsey our CEO:

For 2023, our last completed fiscal year:

the median of the annual total compensation of all employees of the Company (other than Ms. Apsey), was $180,806; and

the annual total compensation of Ms. Apsey as reported in the Summary Compensation Table was $4,756,904.

110

Based on this information, Ms. Apsey’s 2023 annual total compensation was estimated to be 26 times the median annual total compensation for all employees, other than Ms. Apsey.

We determined that, as of December 31, 2023, our employee population consisted of 747 individuals with all of those individuals located in the United States. To identify the “median employee” from our employee population, excluding Ms. Apsey, we utilized a consistently applied compensation measure that included the sum of each employee’s 2023 annualized base salary as of December 31, 2023 as reflected in our payroll records, and target 2023 awards made under our ACPB plan, 2017 Omnibus Plan, Executive Omnibus Plan and Fortis Inc. 2020 Restricted Share Unit Plan that were not paid in 2023. We arrayed these values to select our “median employee.”

Under Item 402(u), a company is permitted to identify its “median employee” once every three years if there has been no significant change to its employee population or employee compensation arrangements that would result in a significant change to its pay ratio disclosure. We updated our “median employee” for 2023 as it had been three years since we had last identified the “median employee” for this analysis.

Using our “median employee” and Ms. Apsey, we calculated the applicable Summary Compensation Table values for each according to applicable SEC rules.

Director Compensation

The following table provides information concerning the compensation of each person who served as a non-employee director of the Company during 2023.

____________________________

(1)Includes annual Board retainer and committee chairmanship retainer, as well as a chairperson fee (for Ms. Pierce only).

Directors who are employees of the Company do not receive separate compensation for their services as a director. All non-employee directors are compensated under our non-employee director compensation policy, pursuant to which they are paid an annual cash retainer of $145,000. In addition, we pay an additional cash retainer of $20,000 annually to the chair of each Board committee and $55,000 annually to our chairperson. We do not pay per-meeting fees under the policy. Non-employee directors are reimbursed for their out-of-pocket expenses incurred for the performance of their duties as directors.

We maintain a Director Deferred Compensation Plan under which nonqualified deferred compensation is permissible. Only non-employee directors of the Company are eligible to participate in this plan. Directors are allowed to defer up to 100% of their annual board compensation. Investment earnings are based on the various investment options available under the plan and are selected by the individual directors. Distributions will be made when the director ceases to serve on the Board and/or ceases to provide other non-employee consulting services to the Company or any Fortis entity. None of the directors participated in this plan in 2023.

ITEM 13.     CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE.

CERTAIN TRANSACTIONS

Pursuant to its charter, the Governance and Human Resources Committee is charged with monitoring and reviewing issues involving independence and potential conflicts of interest with respect to our directors and executive officers. The Committee also determines whether or not a particular relationship serves the best interest of the Company and its shareholder and whether the relationship should be continued or eliminated. In addition, our Code of Conduct and Ethics generally forbids conflicts of interest unless approved by the Board or a designated committee.

112

Although the Company does not have a written policy with regard to the approval of transactions between the Company and its executive officers and directors, each director and officer must annually submit a form to the General Counsel disclosing his or her conflicts or potential conflicts of interest or certifying that no such conflicts of interest exist. Throughout the year, if any transaction constituting a conflict of interest arises or circumstances otherwise change that would cause a director’s or officer’s annual conflict certification to become incorrect, the director or officer must inform the General Counsel of such circumstances. The Committee reviews existing conflicts as well as potential conflicts of interest and determines whether any further action is necessary, such as recommending to the Board whether a director or officer should be requested to offer his or her resignation. Where the Board makes a determination regarding a potential conflict of interest, a majority of the Board (excluding any interested member or members) shall decide upon an appropriate course of action. Additionally, any director or officer who has a question about whether a conflict exists must bring it to the attention of the Company’s General Counsel or Chairperson of the Committee.

DIRECTOR INDEPENDENCE

Based on the absence of any material relationship between them and us, other than their capacities as directors, the Board has determined that Mmes. Bell, Frodl and Pierce and Messrs. Elliott, Hawkins, Jr., Prust, and Rothwell are “independent” as defined in the Shareholders Agreement. In addition, our Board has determined that, as the committees are currently constituted, a majority of the members of the Audit and Risk Committee are “independent” as required in its charter. None of the directors determined to be independent is or ever has been employed by us.

An independent director under the Shareholders Agreement is a director who meets all of the following requirements: (a) is elected by the shareholders of ITC Investment Holdings; (b) is designated as an independent director by the ITC Investment Holdings’ board and Company Board, or the shareholders of ITC Investment Holdings; (c) is not a director that is nominated by Finn Investment Pte Ltd or any successor or permitted assign thereof and appointed as a member of the ITC Investment Holdings’ board and Company Board in accordance with the Shareholders Agreement; (d) is not and during the three years prior to being designated as an independent director has not been any of the following: (i) a director of FortisUS or any of its affiliates (other than ITC Investment Holdings or the Company); or (ii) an officer or employee of ITC Investment Holdings, the Company, FortisUS or any of their affiliates; and (e) would meet the definition of “independent director” under the NYSE Listed Company Manual if such director were a member of the board of directors of Fortis, FortisUS, ITC Investment Holdings, or the Company (assuming, in the case of FortisUS, ITC Investment Holdings and the Company, that such entities were listed on the NYSE).

Mr. Elliott serves on the board of directors of UNS Energy Corporation, a wholly-owned subsidiary of FortisUS. When determining Mr. Elliott’s independence, the board and shareholders agreed to waive the requirements set forth in the definition of independent director under the Shareholders Agreement which states that a director is not and during the three years prior to being designated as a director of the company has not served as a director of FortisUS or any of its affiliates.

SCHEDULE I — Condensed Financial Information of Registrant

ITC HOLDINGS CORP.

NOTES TO CONDENSED FINANCIAL STATEMENTS (PARENT COMPANY ONLY)

1.     GENERAL

For ITC Holdings Corp.’s (“ITC Holdings,” “we,” “our” and “us”) presentation (parent company only), the investment in subsidiaries is accounted for using the equity method. The condensed parent company financial statements and notes should be read in conjunction with the consolidated financial statements and notes of ITC Holdings appearing in this Annual Report on Form 10-K.

As a holding company with no business operations, ITC Holdings’ assets consist primarily of investments in our subsidiaries. ITC Holdings’ material cash inflows are only from dividends and other payments received from our subsidiaries, the proceeds raised from the sale of debt securities, issuances under our commercial paper program and borrowings under our Revolving Credit Agreement. ITC Holdings may not be able to access cash generated by our subsidiaries in order to fulfill cash commitments. The ability of our subsidiaries to make dividend and other payments to us is subject to the availability of funds after taking into account their respective funding requirements, the terms of their respective indebtedness, the regulations of the FERC under the FPA and applicable state laws. In addition, there are practical limitations on using the net assets of each of our Regulated Operating Subsidiaries as of December 31, 2023 for dividends based on management's intent to maintain the FERC-approved capital structure targeting 60% equity and 40% debt for each of our Regulated Operating Subsidiaries. These net assets are included in Schedule I as the line-item “Investments in subsidiaries.” Each of our subsidiaries, however, is legally distinct from us and has no obligation, contingent or otherwise, to make funds available to us.

2.     DEBT

As of December 31, 2023, the maturities of our debt outstanding were as follows:

(In millions of USD)
2024	$	400
2025	—
2026	400
2027	1,400
2028	—
2029 and thereafter	1,700
Total	$	3,900

Refer to Note 9 to the consolidated financial statements for additional information on the ITC Holdings Senior Notes, the ITC Holdings Revolving Credit Agreement, the ITC Holdings commercial paper program and the ITC Holdings derivative instruments and hedging activities.

Fixed Rate Debt

Based on the borrowing rates obtained from third party lending institutions currently available for bank loans with similar terms and average maturities from active markets, the fair value of the ITC Holdings Senior Notes was $3,792 million and $3,132 million at December 31, 2023 and 2022, respectively. The total book value of the ITC Holdings Senior Notes, net of discount and deferred financing fees, was $3,878 million and $3,331 million at December 31, 2023 and 2022, respectively. The fair values of the ITC Holdings Senior Notes represent Level 2 under the three-tier hierarchy described in Note 12 to the consolidated financial statements.

Revolving Credit Agreements

At December 31, 2023, we did not have a balance outstanding under our Revolving Credit Agreement. As of December 31, 2022 we had $10 million outstanding under our revolving credit agreements, which are variable rate loans. The fair value of these loans approximates book value based on the borrowing rates currently available for variable rate loans obtained from third party lending institutions. The fair values of the revolving

125

credit agreements represent Level 2 under the three-tier hierarchy described in Note 12 to the consolidated financial statements.

Other Financial Instruments

The carrying value of other financial instruments included in current assets and current liabilities, including cash and cash equivalents, special deposits and commercial paper, approximates their fair value due to the short-term nature of these instruments.

3.     RELATED PARTY TRANSACTIONS

Related Party Receivables and Payables

We may incur charges from our subsidiaries for general corporate expenses incurred. In addition, we may perform additional services for, or receive additional services from our subsidiaries. These transactions are in the normal course of business and payments for these services are settled through accounts receivable and accounts payable, as necessary. We generally settle our intercompany balances with our affiliates on a net basis monthly.

Retirement Benefits

We are the plan sponsor for a pension plan, other postretirement plans and a defined contribution plan. The benefits-related expenses recorded by our affiliates result from the inclusion of benefit costs as a component of the total charge for services performed by our employees under the cost assignment and allocation methods used by us and our subsidiaries.

Intercompany Tax Sharing Arrangement

We file consolidated income tax returns that include our affiliates, which are taxed as a corporation for federal and Michigan income tax purposes. We operate under an intercompany tax sharing arrangement with our subsidiaries and as a result may receive or pay federal and state income tax based on their stand-alone company tax positions.

____________________________

(a)The net income tax payments were pursuant to intercompany tax sharing arrangements, and the total of these tax payments is presented as a net cash outflow or inflow from operating activities in the condensed parent company statements of cash flows. Other reconciling items between the parent company and the consolidated tax liabilities are presented as deferred and other income taxes in the adjustments to reconcile net income to net cash provided by operating activities. Additionally, ITC Holdings paid its subsidiaries for NOLs utilized by the consolidated group.

Intercompany Loan Agreement

On September 21, 2020, we advanced an intercompany loan to ITCTransmission totaling $50 million, due September 21, 2022. On January 14, 2022, ITCTransmission repaid the intercompany loan in full with proceeds from the issuance of First Mortgage Bonds on January 14, 2022. We received interest payments of less than $1 million and $1 million during the years ended December 31, 2022 and 2021, respectively, from ITCTransmission associated with this intercompany loan.

Additionally, at December 31, 2022 we had a $4 million intercompany loan with a subsidiary, due June 1, 2046. On June 1, 2023, the subsidiary repaid the intercompany loan in full. We received principal and interest payments of $4 million, less than $1 million and $1 million for the years ended December 31, 2023, 2022 and 2021, respectively, from the subsidiary associated with this intercompany loan.

ARTICLE II

INTERPRETATION

2.1Governing Law

The Plan shall be interpreted and enforced in accordance with the laws of the State of Michigan, without regard to the conflict of law principles thereof. The participation of a Participant in the Plan shall be construed as acceptance of the terms and conditions of the Plan by such Participant and as the Participant’s agreement to be bound thereby.

2.2Severability

If any provision of the Plan is determined by a court of competent jurisdiction to be invalid, illegal or unenforceable in any respect, all other provisions of this Plan shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto.

2.3References

The division of this Plan into articles and sections and the insertion of headings are for convenience of reference only and shall not affect the construction or interpretation of this Plan. Words importing the singular number only shall include the plural and vice versa and words importing the use of any gender shall include all genders. Use of the term “including” shall in each case be construed to mean “including without limitation.”

2.4Fractional Units

6

Fractional Units are permitted under the Plan.

2.5Code Section 409A

(a)It is intended that each Award granted under this Plan shall be exempt from or comply with the requirements of Code Section 409A. This Plan shall be construed, administered, and governed in a manner that effects such intent, and the Committee shall not take any action that would be inconsistent with such intent. Without limiting the foregoing, no Award shall be deferred, accelerated, extended, paid out, settled, adjusted, substituted, exchanged or modified in a manner that would cause the Award to fail to satisfy the conditions of an applicable exemption from, or compliance with, the requirements of Code Section 409A or otherwise would subject the Participant to additional tax imposed under Code Section 409A. Although the Company will use good faith efforts to avoid the imposition of taxation, interest and penalties under Code Section 409A, the tax treatment of the benefits provided under this Plan is not warranted or guaranteed. Neither the Company, its Subsidiaries nor their respective directors, officers, employees or advisers shall be held liable for any taxes, interest, penalties or other monetary amounts owed by a Participant (or any other individual claiming a benefit through the Participant) as a result of this Plan.

(b)To the extent required to comply with Code Section 409A, references in this Plan to a termination or cessation of employment or like terms shall mean a Separation from Service.

(c)Notwithstanding anything in the Plan to the contrary, if at the time of a Participant’s Separation from Service, the Participant is considered to be a Specified Employee, to the extent any Award is subject to the requirements of Code Section 409A and is payable upon the Participant’s Separation from Service, such payment shall not commence prior to the first Business Day following the date which is six months after the Participant’s Separation from Service (or if earlier than the end of the six month period, the date of the Participant’s death). For the avoidance of doubt, the provisions of this Section 2.5(c) shall not apply to any payment that becomes due prior to the Participant’s Separation from Service, any payment that becomes due as a result of the Participant’s death, or any payment with respect to an Award that qualifies for an exception to the requirements of Code Section 409A.

ARTICLE III

ESTABLISHMENT OF THE PLAN

3.1Establishment

The Company is establishing the Plan for Participants which shall be effective as of January 1, 2024. Upon the effectiveness of the Plan, no further awards may be granted under the ITC Holdings Corp. 2017 Omnibus Plan.

3.2No Additional Rights

7

Nothing herein contained shall be deemed to give any Person the right to be retained as an Employee or Director or to otherwise be retained in the Service of the Company or a Subsidiary. Units are not Common Shares and will not entitle a Participant to any shareholder rights, including voting rights, dividend entitlement or rights on liquidation, dissolution or winding-up of Fortis.

ARTICLE IV

AWARDS

4.1Grant of Unit Awards

(a)The Committee, in its discretion, may, at any time and from time to time, grant Unit Awards in accordance with the terms and conditions hereof to Eligible Individuals; provided, however, that Unit Awards granted to Prospective Employees or Directors shall be conditioned on such individual actually becoming an Employee or Director, and such Unit Award shall not be considered granted or outstanding until such individual commences Service as an Employee or Director. The terms of a Participant’s Unit Award shall be set forth in the Participant’s Agreement.

(b)No certificates shall be issued with respect to Units. All Units granted hereunder shall be reflected in the Unit Accountof the Participant.

(c)The Units in a Unit Account shall be credited with Dividend Equivalents. Dividend Equivalents shall be subject to the same terms and conditions as the Units in respect of which such Dividend Equivalents are credited. Notwithstanding the foregoing, the Committee shall have discretion to modify the terms and timing of payment relating to Dividend Equivalents or to determine that any Unit Award is not entitled to dividend equivalents, in each case as set forth in the applicable Agreement.

4.2Grant of Incentive Awards

(a)The Committee, in its discretion, may, at any time and from time to time, grant Incentive Awards in accordance with the terms and conditions hereof to Eligible Individuals; provided, however, that Incentive Awards granted to Prospective Employees or Directors shall be conditioned on such individual actually becoming an Employee or Director, and such Incentive Award shall not be considered granted or outstanding until such individual commences Service as an Employee or Director. The Payment Criteria and Payment Criteria Period shall be set forth in an Agreement authorized by the Committee.

(b)Incentive Awards may be earned, if at all, based upon the level of achievement of the Payment Criteria over the Payment Criteria Period, as determined by the Committee and as specified in the Agreement.

(c)Incentive Awards shall not be denominated in Units and shall only be paid in cash.

8

4.3Adjustments. In the event of any stock dividend, stock split, combination or exchange of shares, merger, consolidation, spin-off or other distribution (other than normal cash dividends) of Fortis’s assets to the shareholders, or any other change affecting the Common Shares, such proportionate adjustments, if any, as the Committee in its sole discretion may deem appropriate to reflect such change shall be made with respect to the number of Units outstanding (including, for the avoidance of doubt, Dividend Equivalents) under the Plan. In the event Fortis or the Company is not the surviving entity in a merger, consolidation or amalgamation with another entity or in the event of a liquidation, reorganization and in the absence of any surviving entity’s assumption of outstanding awards made under the Plan, the Committee may provide for appropriate settlements of Units.

4.4Committee Discretion. Subject to the terms and conditions of the Plan, the Committee shall determine the terms and conditions of any Awards in addition to those set forth herein at the time of grant or from time to time following the Grant Date, including any additional conditions with respect to the payment of Awards, which do not conflict with the Plan.

ARTICLE VII

ADMINISTRATION

7.1Administration

(a)The Plan shall be administered by the Committee. Among other things, the Committee shall have full and complete authority to interpret the Plan, establish, amend and rescind any rules and regulations relating to the Plan, and make any other determinations that it deems necessary or desirable for the administration of the Plan. TheCommittee may correct any defect or supply any omission or reconcile any inconsistency in the Plan or any Agreement in the manner and to the extent the Committee deems necessary or desirable. Any decisions of the Committee relating to the interpretation and administration of the Plan, as described herein, shall lie within its sole and absolute discretion and shall be final, conclusive and binding on all parties concerned and their beneficiaries, legal representatives and successors, as applicable, and the shareholders of Fortis. No member of the Committee shall be liable for any action or determination made in good faith with respect to the Plan or any Award hereunder.

(b)In addition to any other powers set forth in the Plan, but subject to Code Section 409A and the provisions of the Plan, the Committee shall have the full and final power and authority, in its discretion to:

(i)amend, modify, or cancel any Award, or to waive any restrictions or conditions applicable to any Award;

(ii)    accelerate, continue, or defer the exercisability or Vesting of any Award or any shares acquired pursuant thereto;

(iii)     authorize, in conjunction with any applicable deferred compensation plan of the Company, that the receipt of cash subject to any Award under this Plan may be deferred under the terms and conditions of such deferred compensation plan; and

(iv)     determine the terms and conditions of Awards granted to Participants and whether such terms and conditions have been satisfied.

No amendment, modification, or cancellation of an outstanding Award or Agreement shall in any manner materially and adversely affect any then outstanding Award under the Plan without the consent of the Participant holding such Award, except as set forth in any Agreement relating to the Award, as set forth in Section 2.2 or 4.3 or to bring the Plan and/or an Award into compliance with the requirements of Code Section 409A or to qualify for an exemption under Code Section 409A.

(a)In exercising its authority under Section 7.1, the Committee shall from time to time ensure it is informed as to the terms and conditions of any similar plans of Fortis and Fortis’s other subsidiaries in order that it may consider such terms in exercising such authority.

7.2Unfunded Obligation

11

Unless otherwise determined by the Committee, the Plan will be an unfunded obligation of the Company and the Company’s obligations hereunder shall constitute general, unsecured obligations, payable solely out of its general assets, and no Participant or other Person shall have any right to any specific assets of the Company. The Company shall not segregate any assets for the purpose of funding its obligations with respect to the Awards granted hereunder and shall not be deemed to be a trustee of any amounts to be distributed or paid pursuant to the Plan. No liability or obligation of the Company under the Plan shall be deemed to be secured by any pledge of, or encumbrance on, any property or assets of the Company. To the extent any individual holds rights under the Plan, such rights (unless otherwise determined by the Committee) shall be no greater than the rights of an unsecured general creditor of the Company.

7.3Amendment, Suspension and Termination

The Plan may be amended, suspended or terminated at any time by the Board, in whole or in part, except as to rights already accrued hereunder unless the affected Participant consents to any such change in writing; provided, however, that an amendment, suspension or termination the effect of which is not adverse to such Participant shall not require such Participant’s consent. If the Plan is terminated, outstanding awards shall, at the discretion of the Committee, either (a) subject to Section 2.5, vest and become immediately payable in accordance with Section 5.2, or (b) remain outstanding and in effect in accordance with their applicable terms and conditions. In the event of a Change of Control, the Company shall pay all outstanding amounts in accordance with the applicable Agreement and the Plan will terminate as of the later of the effective date of such Change of Control or the completion of the payment of all Awards under the Plan.

7.4Cost of Administration

The Company will be responsible for all costs relating to the administration of the Plan.

7.5Withholding Taxes

The Company shall withhold from any payment to or for the benefit of a Participant any amount required to comply with Applicable Law relating to the withholding of tax or the making of any other source deductions, including on the amount, if any, included in income of a Participant and may adopt and apply such rules and regulations as in its opinion will ensure that the Company will be able to so comply. To the extent that the Company is required under Applicable Law to withhold tax at any time other than upon payment of Awards pursuant to this Plan (for example, if payment is deferred pursuant to Section 7.6 hereof), then the Company shall have the right in its sole discretion to (a) require the Participant to pay or provide for payment of the required tax withholding, or (b) deduct the required tax withholding from any amount of salary, bonus, incentive compensation or other payment otherwise payable in cash to the Participant.

7.6Deferral

12

Notwithstanding anything contained herein to the contrary, but subject to Code Section 409A, Participants may elect to defer receipt of payment of the Awards in accordance with the terms, and subject to the conditions, of the Company’s Executive Deferred Compensation Plan (and any similar or successor plan that may be in effect from time to time).

ARTICLE VIII

RECOUPMENT

8.1Clawback of Payout Amounts and Units

Notwithstanding any provisions in this Plan or the applicable Agreement to the contrary, all Awards granted hereunder shall be subject to any Company clawback policy in effect from time to time, as such policy may be amended.

ARTICLE IX

MISCELLANEOUS

9.1No Assignment

An Award is personal to the Participant and is non-assignable. No Award granted hereunder shall be pledged, hypothecated, charged, transferred, assigned or otherwise encumbered or disposed of by the Participant, whether voluntarily or by operation of law, otherwise than by testate succession or the laws of descent and distribution, and any attempt to do so will be null and void. During the lifetime of the Participant, an Award shall be redeemable only by the Participant and, upon the death of a Participant, the Person to whom the rights shall have passed by testate succession or by the laws of descent and distribution may receive payment of any Awards in accordance with the terms hereof.

9.2Currency

The value and number of Units determined in Section 4.1 with respect to an Award, all dividend equivalents payable with respect to an Award, all Payout Amounts with respect to an Award and all other amounts that may become payable with respect to an Award shall be calculated and paid in U.S. dollars.

9.3Successors and Assigns

The Plan shall be binding on all successors and assigns of the Company and a Participant including, if applicable, the estate of such Participant and the executor, administrator or trustee of such estate, or any receiver or trustee in bankruptcy or representative of the Participant’s creditors.

IN WITNESS WHEREOF, the Company caused this Plan to be executed by itsduly authorized officer as of November 9, 2023.

RECENT ACCOUNTING PRONOUNCEMENTS

RECENT ACCOUNTING PRONOUNCEMENTS

Recently Issued Pronouncements

Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued authoritative guidance to improve reportable segment disclosure requirements, thereby enabling investors to better understand an entity’s performance and assess potential future cash flows. The new guidance requires that public entities disclose, on an annual and interim basis, additional information related to significant segment expenses regularly provided to the chief operating decision maker and other segment items. The guidance also contains several other provisions, notably requiring disclosure in interim periods of all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280 of the FASB’s Accounting Standards Codification. The guidance is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are evaluating the impact of the new guidance on our disclosures.

Enhancements to Income Tax Disclosures

In December 2023, the FASB issued authoritative guidance modifying the disclosure requirements for income tax. This update is intended to provide investors information to better assess how an entity’s operations and related tax risks, tax planning and operational opportunities affect its tax rate and prospects for future cash flows. Notable changes in the new guidance include disaggregation of income tax information by jurisdiction and changes to the presentation of information for the reconciliation of effective tax rates. The guidance is effective for fiscal years beginning after December 15, 2024 with early adoption permitted. We are evaluating the impact of the new guidance on our disclosures.

SIGNIFICANT ACCOUNTING POLICIES

Dec. 31, 2023

Accounting Policies [Abstract]

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES

A summary of the major accounting policies followed in the preparation of the accompanying consolidated financial statements, which conform to GAAP, is presented below:

Principles of Consolidation — ITC Holdings consolidates its majority owned subsidiaries. We eliminate all intercompany balances and transactions.

Use of Estimates — The preparation of the consolidated financial statements requires us to use estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results may differ from our estimates.

Regulation — Our Regulated Operating Subsidiaries are subject to the regulatory jurisdiction of the FERC, which issues orders pertaining to rates, recovery of certain costs, including the costs of

transmission assets and regulatory assets, conditions of service, accounting, financing authorization and operating-related matters. The utility operations of our Regulated Operating Subsidiaries meet the accounting standards set forth by the FASB for the accounting effects of certain types of regulation. These accounting standards recognize the cost-based rate setting process, which results in differences in the application of GAAP between regulated and non-regulated businesses. These standards require the recording of regulatory assets and liabilities for certain transactions that would have been recorded in the statements of comprehensive income in non-regulated businesses. Regulatory assets represent costs that will be included as a component of future tariff rates and regulatory liabilities represent amounts provided in the current tariff rates that are intended to recover costs expected to be incurred in the future or amounts to be refunded to customers.

Cash and Cash Equivalents — We consider all unrestricted highly-liquid temporary investments with an original maturity of three months or less at the date of purchase to be cash equivalents.

Restricted Cash — Restricted cash includes cash that is legally or contractually restricted for use or withdrawal or are formally set aside for a specific purpose. Restricted cash primarily represents cash on deposit to pay for vegetation management, land easements and land purchases for the purpose of transmission line construction as well as amounts liquidated to make benefit payments related to our supplemental benefit plans.

Inventories — Materials and supplies inventories are valued at average cost. Additionally, the costs of warehousing activities are recorded here and included in the cost of materials when requisitioned.

Property, Plant and Equipment — Depreciation and amortization expense on property, plant and equipment was $300 million, $286 million and $223 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Property, plant and equipment in service at our Regulated Operating Subsidiaries is stated at its original cost when first devoted to utility service. The gross book value of assets retired less salvage proceeds is charged to accumulated depreciation. The provision for depreciation of transmission assets is a significant component of our Regulated Operating Subsidiaries’ cost of service under FERC-approved rates. Periodically, we perform depreciation studies of the assets at our Regulated Operating Subsidiaries. The results of these studies are submitted to and require approval from the FERC prior to changing our depreciation rates. Depreciation is computed over the estimated useful lives of the assets using the straight-line method for financial reporting purposes and accelerated methods for income tax reporting purposes. The composite depreciation rate for our Regulated Operating Subsidiaries included in our consolidated statements of comprehensive income was 2.4% for each of the years ended December 31, 2023 and 2022 and 2.0% for the year ended December 31, 2021. The composite depreciation rates include depreciation primarily on transmission station equipment, towers, poles and overhead and underground lines that have a useful life ranging from 43 to 70 years. The portion of depreciation expense related to asset removal costs is added to regulatory liabilities or deducted from regulatory assets and removal costs incurred are deducted from regulatory liabilities or added to regulatory assets. Certain of our Regulated Operating Subsidiaries capitalize to property, plant and equipment AFUDC in accordance with FERC regulations. AFUDC represents the composite cost incurred to fund the construction of assets, including interest expense and a return on equity capital devoted to construction of assets. The interest component of AFUDC was a reduction to interest expense of $11 million, $9 million and $8 million for the years ended December 31, 2023, 2022 and 2021, respectively.

For acquisitions of property, plant and equipment greater than the net book value (other than asset acquisitions accounted for under the purchase method of accounting that result in goodwill), the acquisition premium is recorded to property, plant and equipment and amortized over the estimated remaining useful lives of the assets using the straight-line method for financial reporting purposes and accelerated methods for income tax reporting purposes.

Property, plant and equipment includes capital equipment stated at original cost consisting of items that are expected to be used exclusively for capital projects.

Property, plant and equipment at our non-regulated subsidiaries is stated at its acquired cost. Proceeds from salvage less the net book value of the disposed assets is recognized as a gain or loss on disposal. Depreciation is computed based on the acquired cost less expected residual value and is

recognized over the estimated useful lives of the assets on a straight-line method for financial reporting purposes and accelerated methods for income tax reporting purposes.

Generator Interconnection Projects and Contributions in Aid of Construction — Certain capital investment at our Regulated Operating Subsidiaries relates to investments made under GIAs. The GIAs typically consist of both transmission network upgrades, which are a category of upgrades deemed by the FERC to benefit the transmission system as a whole, as well as direct connection facilities, which are necessary to interconnect the generating facility to the transmission system and primarily benefit the generating facility. GIAs typically require the generator to make a contribution in aid of construction to our Regulated Operating Subsidiaries to cover the cost of certain investments made by us as part of the agreement. However, we may fund construction of certain projects without contributions from the generators.

Our investments in transmission facilities are recorded to property, plant and equipment, and are recorded net of any contribution in aid of construction. We also receive refundable deposits from the generator for certain investment in network upgrade facilities in advance of construction, which are recorded to current or non-current liabilities depending on the expected refund date.

Jointly Owned Utility Plant/Coordinated Services — Certain of our Regulated Operating Subsidiaries have agreements with other utilities for the joint ownership of assets as described in Note 15. We account for these jointly owned assets by recording property, plant and equipment for the percentage of our undivided ownership interest. Various agreements provide the authority for construction of capital improvements and the operating costs associated with the substations and lines. Generally, each party is responsible for the capital, operation and maintenance, and other costs of these jointly owned facilities based upon each participant’s undivided ownership interest, and each participant is responsible for providing its own financing. Our participating share of expenses associated with these jointly held assets is primarily recorded within operation and maintenance expense on our consolidated statements of comprehensive income.

Fair Value Through Net Income — We have certain investments in mutual funds, including fixed income securities and equity securities, that are classified as fair value through net income. The investments fund our two supplemental nonqualified, noncontributory retirement benefit plans for selected management employees as described in Note 11, as well as other deferred compensation plans. Gains and losses associated with these investments are recorded in other expenses (income), net in the consolidated statements of comprehensive income.

Impairment of Long-Lived Assets — Other than goodwill, our long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If the carrying amount of the asset exceeds the expected undiscounted future cash flows generated by the asset, the asset is written down to its estimated fair value and an impairment loss is recognized in our consolidated statements of comprehensive income.

Goodwill — Goodwill is not subject to amortization; however, goodwill is required to be assessed for impairment, and a resulting write-down, if any, is to be reflected in operating expense. We have goodwill recorded relating to our acquisitions of ITCTransmission and METC, and ITC Midwest’s acquisition of the IP&L transmission assets. Goodwill is reviewed at the reporting unit level at least annually for impairment and whenever facts or circumstances indicate that the value of goodwill may be impaired. Our reporting units are ITCTransmission, METC and ITC Midwest as each entity represents an individual operating segment to which goodwill has been assigned. At December 31, 2023 and 2022, we had goodwill balances recorded at ITCTransmission, METC and ITC Midwest of $173 million, $454 million and $323 million, respectively.

In order to perform an impairment analysis, we have the option of performing a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, in which case no further testing is required. If an entity bypasses the qualitative assessment or performs a qualitative assessment but determines that it is more likely than not that a reporting unit’s fair value is less than its carrying amount, a quantitative, fair value-based test is performed to assess and measure goodwill impairment, if any. If a quantitative assessment is performed, we determine the fair value of our reporting

units using valuation techniques based on discounted future cash flows under various scenarios and consider estimates of market-based valuation multiples for companies within the peer group of our reporting units.

We completed our annual goodwill impairment test for our reporting units as of October 1, 2023 and determined that no impairment exists. There were no events subsequent to October 1, 2023 that indicated impairment of our goodwill.

Deferred Financing Fees and Discount or Premium on Debt — Costs related to the issuance of long-term debt are generally recorded as a direct deduction from the carrying amount of the related debt and amortized over the life of the debt. Debt issuance costs incurred prior to the associated debt funding are presented as an asset. Unamortized debt issuance costs associated with the revolving credit agreements, commercial paper and other similar arrangements are presented as an asset (regardless of whether there are any amounts outstanding under those credit facilities) and amortized over the life of the particular arrangement. The debt discount or premium related to the issuance of long-term debt is recorded to long-term debt and amortized over the life of the debt. We recorded $6 million for each of the years ended December 31, 2023 and 2022 and $5 million for the year ended December 31, 2021 to interest expense for the amortization of deferred financing fees and debt discounts.

Asset Retirement Obligations — A conditional asset retirement obligation is a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within our control. We have identified conditional asset retirement obligations primarily associated with the removal of equipment containing PCBs and asbestos. We record a liability at fair value for a legal asset retirement obligation in the period in which it is incurred. When a new legal obligation is recorded, we capitalize the costs of the liability by increasing the carrying amount of the related long-lived asset. We accrete the liability to its present value each period and depreciate the capitalized cost over the useful life of the related asset. At the end of the asset’s useful life, we settle the obligation for its recorded amount. We recognize regulatory assets for the timing differences between the incurred costs to settle our legal asset retirement obligations and the recognition of such obligations as applicable for our Regulated Operating Subsidiaries. Our asset retirement obligations of $5 million as of December 31, 2023 and 2022 are included in other liabilities.

Derivatives and Hedging — We may use derivative financial instruments to manage our exposure to fluctuations in interest rates. For derivative instruments that have been designated and qualify as cash flow hedges of the exposure to variability in expected future cash flows, the unrealized gain or loss on the derivative is initially reported, net of tax, as a component of other comprehensive income (loss) and reclassified to the consolidated statements of comprehensive income when the underlying hedged transaction affects net income. Cash flows related to derivative instruments that are designated in hedging relationships are generally classified on the consolidated statements of cash flows within cash flows from operating activities. The fair values of derivatives are recognized as current or long-term assets and liabilities depending on the timing of settlements and resulting cash flows. Refer to Note 9 for additional discussion regarding derivative instruments.

Contingent Obligations — We are subject to a number of federal and state laws and regulations, as well as other factors and conditions that potentially subject us to environmental, litigation, income tax and other contingencies. We periodically evaluate our exposure to such contingencies and record liabilities for those matters where a loss is considered probable and reasonably estimable. We reverse the liabilities recorded for those matters when a loss is no longer considered probable or the liabilities are otherwise settled. Our liabilities exclude any estimates for legal costs not yet incurred associated with handling these matters, which could be material. The adequacy of liabilities recorded can be significantly affected by external events or conditions that can be unpredictable; thus, the ultimate outcome of such matters could materially affect our consolidated financial statements.

Revenues — Substantially all of our revenue from contracts with customers is generated from providing transmission services to customers as services are provided based on our FERC-approved cost-based Formula Rates. We record a reserve for revenue subject to refund when such refund is probable and can be reasonably estimated. This reserve is recorded as a reduction to operating revenues.

The cost-based Formula Rates at our Regulated Operating Subsidiaries include a true-up mechanism that compares the actual revenue requirements of our Regulated Operating Subsidiaries to their billed revenues for each year to determine any over- or under-collection of revenue requirements and we record a revenue deferral or accrual for the difference. The true-up mechanisms under our Formula Rates are considered alternative revenue programs of rate-regulated utilities. Operating revenues arising from these alternative revenue programs are presented on our consolidated statements of comprehensive income in the line “Formula Rate true-up”, which is separate from the reporting of our tariff revenues, which are presented in the line “Transmission and other services.” Only the initial origination of our alternative revenue program revenue is reported in the Formula Rate true-up line on our consolidated statements of comprehensive income. When those amounts are subsequently included in the price of utility service and billed or refunded to customers, we account for that event as the recovery or settlement of the associated regulatory asset or regulatory liability, respectively. Refer to Note 6 under “Cost-Based Formula Rates with True-Up Mechanism” and Note 4 under “Formula Rate True-Up” for a discussion of our revenue accounting under our cost-based Formula Rates.

Share-Based Payment — Under long-term incentive plans, we grant long-term incentive awards consisting of PBUs and SBUs to employees, including executive officers, of ITC Holdings. Generally, each PBU and SBU granted is valued based on one share of Fortis common stock traded on the Toronto Stock Exchange, converted to U.S. dollars and settled only in cash. However, certain SBUs granted to the executives may settle in cash, 100% Fortis common stock, or 50% cash and 50% Fortis common stock depending on executives’ settlement elections and whether certain share ownership requirements are met. All PBUs and SBUs are classified as liability awards and generally vest on the third January 1st following the grant date, provided the service and performance criteria, as applicable, are satisfied, and will be settled during the subsequent quarter. However, certain awards may vest over a shorter period or on the grant date if certain retirement eligibility criteria are met. The PBUs and SBUs earn dividend equivalents, which are also re-measured and settled consistent with the target award at the end of the vesting period. The granted awards and related dividend equivalents have no shareholder rights.

Compensation cost is recognized over the expected vesting period and remeasured each reporting period based on Fortis’ stock price. The PBUs are also remeasured each reporting period based on the applicable market and performance conditions in the awards. Compensation cost is adjusted for forfeitures in the period in which they occur and the final measure of compensation cost for the awards is based on the cash settlement amount.

Refer to Note 14 for additional discussion of the plans.

Comprehensive Income (Loss) — Comprehensive income (loss) is the change in stockholder’s equity during a period arising from transactions and events from non-owner sources, including net income and any gain or loss arising from derivative financial instruments.

Income Taxes — Deferred income taxes are recognized for the expected future tax consequences of events that have been recognized in the consolidated financial statements or tax returns. Deferred income tax assets and liabilities are determined based on the differences between the financial statements and the tax bases of various assets and liabilities, using the tax rates expected to be in effect for the year in which the differences are expected to reverse, and classified as non-current in our consolidated statements of financial position.

The accounting standards for uncertainty in income taxes prescribe a recognition threshold and a measurement attribute for tax positions taken, or expected to be taken, in a tax return that may not be sustainable. As of December 31, 2023, we have not recognized any uncertain income tax positions.

We file our federal and Michigan income tax returns as part of the FortisUS consolidated tax returns and we are a party to an intercompany tax sharing agreement that establishes the method for determining tax liabilities that are due and allocating tax attributes that are utilized on the consolidated income tax returns. We continue to file with various other state and city jurisdictions where we have a separate return filing obligation. Our prior consolidated federal tax returns are no longer subject to U.S. federal tax examinations for tax years 2019 and earlier. State and city jurisdictions that remain subject to examination range from tax years 2019 to 2022. In the event we are assessed interest or penalties by any income tax jurisdictions, interest and penalties would be recorded as interest expense and other expenses,

respectively, in our consolidated statements of comprehensive income. Refer to Note 10 for additional discussion on income taxes.

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

REVENUE

Our total revenues are comprised of revenues which arise from three classifications including transmission services, other services and Formula Rate true-up. As other services revenue is immaterial, it is presented in combination with transmission services on the consolidated statements of comprehensive income.

Transmission Services

Through our Regulated Operating Subsidiaries, we generate nearly all our revenue from providing electric transmission services over our transmission systems. As independent transmission companies, our transmission services are provided and revenues are received based on our tariffs, as approved by the FERC. We recognize revenue for transmission services over time as transmission services are provided to customers (generally using an output measure of progress based on transmission load delivered). Customers simultaneously receive and consume the benefits provided by the Regulated Operating Subsidiaries’ services. We recognize revenue in the amount to which we have the right to invoice because we have a right to consideration in an amount that corresponds directly with the value to the customer of performance completed to date. As billing agents, MISO and SPP independently bill our customers on a monthly basis and collect fees for the use of our transmission systems. No component of the transaction price is allocated to unsatisfied performance obligations.

Transmission service revenue includes an estimate for unbilled revenues from service that has been provided but not billed by the end of an accounting period. Unbilled revenues are dependent upon a number of factors that require management’s judgment including estimates of transmission network load (for the MISO Regulated Operating Subsidiaries) and preliminary information provided by billing agents. Due to the seasonal fluctuations of actual load, the unbilled revenue amount generally increases during the spring and summer and decreases during the fall and winter. See Note 5 for information on changes in unbilled accounts receivable.

Other Services

Other services revenue consists of rental revenues, easement revenues and amounts from providing ancillary services. A portion of other services revenue is treated as a revenue credit and reduces gross revenue requirement when calculating net revenue requirement under our Formula Rates. Total other services revenue was $6 million for each of the years ended December 31, 2023, 2022 and 2021.

Formula Rate True-Up

The true-up mechanism under our Formula Rates is considered an alternative revenue program of a rate-regulated utility given it permits our Regulated Operating Subsidiaries to adjust future rates in response to past activities or completed events in order to collect our actual revenue requirements under our Formula Rates. In accordance with our accounting policy, only the current year origination of the true-up is reported as a Formula Rate true-up. See “Cost-Based Formula Rates with True-Up Mechanism” in Note 6 for more information on our Formula Rates.

REGULATORY MATTERS

REGULATORY MATTERS

Cost-Based Formula Rates with True-Up Mechanism

The transmission revenue requirements at our Regulated Operating Subsidiaries are set annually using Formula Rates and remain in effect for a one-year period. By updating the inputs to the formula and resulting rates on an annual basis, the revenues at our Regulated Operating Subsidiaries reflect changing operational data and financial performance, including the amount of network load on their transmission systems (for our MISO Regulated Operating Subsidiaries), operating expenses and additions to property, plant and equipment when placed in service, among other items. The formula used to derive the rates does not require further action or FERC filings each year, although the formula inputs remain subject to legal challenge at the FERC. Our Regulated Operating Subsidiaries will continue to use the formula to calculate their respective annual revenue requirements unless the FERC determines the resulting rates to be unjust and unreasonable and another mechanism is determined by the FERC to be just and reasonable. See “Rate of Return on Equity Complaints” in Note 17 for detail on ROE matters for our MISO Regulated Operating Subsidiaries and "ROE and Incentive Adders for Transmission Rates" and “Capital Structure Complaint” discussed herein.

The cost-based Formula Rates at our Regulated Operating Subsidiaries include a true-up mechanism that compares the actual revenue requirements of our Regulated Operating Subsidiaries to their billed revenues for each year to determine any over- or under-collection of revenue requirements. Revenue is recognized for services provided during each reporting period based on actual revenue requirements calculated using the formula. Our Regulated Operating Subsidiaries accrue or defer revenues to the extent that the actual revenue requirement for the reporting period is higher or lower, respectively, than the amounts billed relating to that reporting period. The amount of accrued or deferred revenues is reflected in future revenue requirements and thus flows through to customer bills within two years under the provisions of our Formula Rates.

The net changes in regulatory assets and liabilities associated with our Regulated Operating Subsidiaries’ Formula Rate revenue accruals and deferrals, including accrued interest, were as follows during the year ended December 31, 2023:

(In millions of USD)	Total
Net regulatory liabilities as of December 31, 2022	$	(20)
Net refund of 2021 revenue deferrals and accruals, including accrued interest	11
Net revenue deferral, including accrued interest	(17)
Net accrued interest payable	(2)
Net regulatory liabilities as of December 31, 2023	$	(28)

Regulatory assets and liabilities associated with our Regulated Operating Subsidiaries’ Formula Rate revenue accruals and deferrals, including accrued interest, are recorded in the consolidated statements of financial position as follows:

	December 31,
(In millions of USD)	2023		2022
Current regulatory assets	$	30	$	12
Non-current regulatory assets	20		29
Current regulatory liabilities	(41)		(22)
Non-current regulatory liabilities	(37)		(39)
Net regulatory liabilities	$	(28)	$	(20)

ROE and Incentive Adders for Transmission Rates

The FERC has authorized the use of ROE incentives, or adders, that can be applied to the rates of TOs when certain conditions are met. Our MISO Regulated Operating Subsidiaries and ITC Great Plains utilize ROE adders related to independent transmission ownership and RTO participation. The FERC issued a NOPR on March 20, 2020, and a supplemental NOPR on April 15, 2021, proposing to update its transmission incentives policy to remove incentives for independent transmission ownership and RTO participation and to grant

incentives for certain transmission projects. As of December 31, 2023, no final determination had been made on these NOPRs and we cannot predict whether this will have a material impact on us.

MISO Regulated Operating Subsidiaries

For each of the years ended December 31, 2023, 2022 and 2021, the authorized ROE used by the MISO Regulated Operating Subsidiaries was 10.77% and is composed of a base ROE of 10.02% with a 25 basis point adder for independent transmission ownership and a 50 basis point adder for RTO participation. See “Rate of Return on Equity Complaints” in Note 17 for a discussion of the MISO ROE Complaints.

ITC Great Plains

For each of the years ended December 31, 2023, 2022 and 2021, the authorized ROE used by ITC Great Plains was 11.41% and is composed of a base ROE of 10.66% with a 25 basis point adder for independent transmission ownership and a 50 basis point adder for RTO participation.

Capital Structure Complaint

On May 10, 2022, the Iowa Coalition for Affordable Transmission, including IP&L, filed a complaint with the FERC under Section 206 of the FPA. Specifically, the complaint alleged that ITC Midwest does not meet the FERC’s three-part test for authorizing the use of a utility’s actual capital structure for ratemaking purposes which requires that ITC Midwest 1) issue its own debt without guarantees, 2) have its own credit rating, and 3) have a capital structure within the range of capital structures previously approved by the Commission. The Iowa Coalition for Affordable Transmission asked the FERC to reduce ITC Midwest’s equity component from 60% to 53%. On November 2, 2022, the FERC issued an order denying the complaint. On December 2, 2022, the Iowa Coalition for Affordable Transmission filed a request for rehearing with the FERC. On March 16, 2023, the FERC confirmed the previous order denying the complaint and we consider the matter to be closed.

Depreciation Rate Filings

During 2021, our MISO Regulated Operating Subsidiaries filed revised depreciation rates for their assets which were approved by the FERC in December 2021. The overall depreciation expense at our MISO Regulated Operating Subsidiaries increased beginning on January 1, 2022, which resulted in higher revenue as the increase in depreciation expense flows through to customer bills.

____________________________

(a)Refer to discussion of revenue accruals and deferrals in Note 6 under “Cost-Based Formula Rates with True-Up Mechanism.” Our Regulated Operating Subsidiaries do not earn a return on the balance of regulatory assets for revenue accruals. Interest is accrued on the principal amounts of the revenue accruals and deferrals. The accrued interest is subject to rate recovery along with the principal amount of the revenue accrual or subject to refund through rates along with the principal amount of revenue deferrals in future periods.

Income Taxes Recoverable Related to AFUDC Equity

Accounting standards for income taxes provide that a regulatory asset be recorded if it is probable that a future increase in taxes payable, relating to the book depreciation of AFUDC equity that has been capitalized to property, plant and equipment, will be recovered from customers through future rates. The regulatory asset for the tax effects of AFUDC equity is recovered over the life of the underlying book asset in a manner that is consistent with the depreciation of the AFUDC equity that has been capitalized to property, plant and equipment.

Pensions and Postretirement

Accounting standards for defined benefit pension and other postretirement plans for rate-regulated entities allow for amounts that otherwise would have been recorded to AOCI to be recorded as regulatory assets or liabilities, as appropriate. As the unrecognized amounts recorded to these regulatory assets and liabilities are recognized, the amounts will be recovered from or returned to customers in future rates under our cost-based Formula Rates.

Accrued Asset Removal Costs

The carrying amount of the accrued asset removal costs represents the difference between incurred costs to remove property, plant and equipment and the estimated removal costs included and collected in rates. The portions of depreciation expense included in our depreciation rates related to asset removal costs are recorded as increases to the related regulatory liability. Removal costs incurred reduce the related regulatory liability. Our Regulated Operating Subsidiaries include these regulatory liabilities as increases to accumulated depreciation for rate-making purposes when determining rate base.

Refundable Excess State Income Tax Deductions

As a result of a reduction in corporate income tax rates in certain states we operate in, we revalued our deferred tax balances at the new corporate income tax rates, which resulted in lower net deferred tax liabilities and the recording of a regulatory liability for excess deferred taxes at our Regulated Operating Subsidiaries. Amortization of the excess deferred taxes is determined based on the remaining book lives of utility plant. During the years ended December 31, 2023 and 2022, we recorded $1 million and less than $1 million of amortization related to the excess deferred taxes, respectively. This regulatory liability is included within deferred taxes for rate-making purposes when determining rate base.

Refundable Excess Deferred Federal Income Taxes

Under the Tax Cuts and Jobs Act of 2017, we were required to revalue our deferred tax assets and liabilities at the new federal corporate income tax rate as of the date of the enactment of the act, which resulted in lower net deferred tax liabilities and the establishment of a net regulatory liability for excess deferred taxes at our Regulated Operating Subsidiaries. Amortization of the excess deferred taxes is determined based on a method associated with the related public utility property and returned to customers. During each of the years ended December 31, 2023 and 2022, we recorded $9 million of amortization related to the excess deferred taxes. The net regulatory liability is included within deferred taxes for rate-making purposes when determining rate base.

Derivative Instruments and Hedging Activities

During the second quarter of 2023, we entered into and terminated 10-year U.S. Treasury rate lock contracts with notional amounts totaling $500 million and a weighted-average forward rate yield of 3.46%. The contracts were used to manage interest rate risk associated with the $500 million issuance of unsecured 5.40% Senior Notes at ITC Holdings on June 1, 2023. The comparable reference rate used to determine the gain on settlement of the treasury locks was 3.57%. The treasury locks qualified for cash flow hedge accounting treatment and the cumulative pre-tax gain of $4 million was recorded net of tax in AOCI. This amount is being amortized as a component of interest expense over the term of the related debt. The settlement payment was recognized within cash flows from operating activities in the consolidated statements of cash flows.

During 2022, we terminated $450 million of 5-year interest rate swap contracts that managed interest rate risk associated with the ITC Holdings 4.95% Senior Notes, due September 22, 2027. A summary of the terminated interest rate swaps is provided below:

(In millions of USD, except percentages)	Notional Amount		Weighted Average Fixed Rate of Interest Rate Swaps	Comparable Reference Rate of Notes	Benchmark Rate	Gain on Derivatives		Settlement Date
5-year interest rate swaps	$	375	1.47%	3.44%	LIBOR	$	33	September 2022
5-year interest rate swaps	75		1.54%	3.16%	SOFR	6		September 2022
Total	$	450				$	39

The interest rate swaps qualified for cash flow hedge accounting treatment, and the cumulative pre-tax gain of $39 million was recorded net of tax in AOCI. This amount is being amortized as a component of interest expense over the term of the related debt. The swap settlement payment was recognized within cash flows from operating activities in the consolidated statements of cash flows. For the years ended December 31, 2023 and 2022, we did not have any derivative financial instruments outstanding to manage exposure to fluctuations in interest rates.

Revolving Credit Agreement

On April 14, 2023, ITC Holdings, ITCTransmission, METC, ITC Midwest and ITC Great Plains entered into the Revolving Credit Agreement. In connection with the closing of the Revolving Credit Agreement, the borrowers used funds borrowed under the Revolving Credit Agreement to replace and refinance in full the previous revolving credit agreements. The Revolving Credit Agreement established an unguaranteed, unsecured revolving credit facility under which the borrowers may borrow an aggregate principal amount of $1 billion (subject to certain borrowing sublimits for each of the borrowers as set forth in the Revolving Credit Agreement). The Revolving Credit Agreement has a maturity date of April 14, 2028 and the interest rate is based on a calculation that references, at the applicable borrower’s option, either SOFR or a comparable benchmark as further outlined in the Revolving Credit Agreement.

At December 31, 2023, ITC Holdings and certain of its Regulated Operating Subsidiaries had the following unsecured revolving credit facilities available:

INCOME TAXES

For the years ended December 31, 2023, 2022 and 2021, our effective tax rates were 25.2%, 24.8% and 23.8%, respectively. Our effective tax rate varied from the statutory federal income tax rate due to differences between the book and tax treatment of various transactions as follows:

	Year Ended December 31,
(In millions of USD)	2023		2022		2021
Income tax expense at 21% federal statutory rate	$	130	$	123	$	112

Total income tax provision	$	156	$	146	$	127

____________________________

(a)Amounts for the years ended December 31, 2023 and 2022 include the impact of the remeasurement of certain deferred tax balances and NOLs for Iowa due to the corporate tax rate change discussed herein.

Components of the income tax provision were as follows:

	Year Ended December 31,
(In millions of USD)	2023		2022		2021
Current income tax expense	$	51	$	15	$	—
Deferred income tax expense	105		131		127

Gross deferred income tax assets	234		244
Valuation allowance	(3)		(5)
Net deferred tax liabilities	$	(1,411)	$	(1,303)

We had state income tax NOLs as of December 31, 2023. While we expect to utilize the majority of these state NOLs prior to their expiration, we believe that it is more likely than not that the benefit from certain state NOL carryforwards will not be realized and have recorded a valuation allowance accordingly.

Iowa Corporate Tax Rate

On March 1, 2022, the governor of Iowa signed an act into law that contains provisions to reduce Iowa’s corporate tax rates if a certain threshold of the state’s annual net corporate income tax receipts is met.

Adjustments to reduce the corporate income tax rate are calculated annually after the end of each fiscal year and may continue until the currently targeted corporate income tax rate of 5.5% is reached.

For Iowa’s fiscal year ended June 30, 2023, net corporate income tax receipts exceeded the prescribed threshold. On September 22, 2023, the Iowa Department of Revenue certified a reduction in the top corporate income tax rate from 8.4% to 7.1%, effective January 1, 2024. We have revalued certain deferred tax balances and net operating losses impacted by the change in the future Iowa corporate income tax rate. As a result, deferred income tax expense of $6 million was recorded during the year ended December 31, 2023. In addition, a regulatory liability of $21 million was recorded as of December 31, 2023 to offset deferred taxes associated with rate base at ITC Midwest.

In September 2022, a reduction in Iowa’s top corporate income tax rate from 9.8% to 8.4% was certified, effective January 1, 2023. As a result, deferred income tax expense of $7 million was recorded during the year ended December 31, 2022 and a regulatory liability of $22 million was recorded as of December 31, 2022 to offset deferred taxes associated with the rate base at ITC Midwest. See Note 7 for additional information on the regulatory liabilities related to the Iowa corporate income tax rate reductions.

RETIREMENT AND BENEFITS AND ASSETS HELD IN TRUST

RETIREMENT BENEFITS AND ASSETS HELD IN TRUST

Pension and Postretirement Plan Benefits

We have a qualified defined benefit pension plan (“retirement plan”) for eligible employees, comprised of a traditional final average pay plan and a cash balance plan. The traditional final average pay plan is noncontributory, covers select employees, and provides retirement benefits based on years of benefit service, average final compensation, and age at retirement. The cash balance plan is also noncontributory, covers substantially all employees and provides retirement benefits based on eligible compensation and interest credits. Our funding practice for the retirement plan is generally to fund the annual net pension cost, though we may adjust our funding as necessary based on consideration of federal funding requirements, the funded status of the plan, and other considerations as we deem appropriate. We did not contribute to the retirement plan in 2023. We made contributions to the retirement plan of $3 million and $4 million in 2022 and 2021, respectively. We expect to contribute $4 million to the retirement plan in 2024.

We also have two supplemental nonqualified, noncontributory, defined benefit pension plans for selected management employees (the “supplemental benefit plans” and collectively with the retirement plan, the “pension plans”). The supplemental benefit plans provide for benefits that supplement those provided by the retirement plan. The obligations under these supplemental benefit plans are included in the pension benefit obligation calculations below. The investments held in trust for the supplemental benefit plans of $48 million and $47 million at December 31, 2023 and 2022, respectively, are not included in the plan asset amounts presented throughout this footnote, but are included in other assets on our consolidated statements of financial position. For the years ended December 31, 2023 and 2021, we contributed $1 million and $3 million, respectively, to these supplemental benefit plans. We did not contribute to the supplemental benefit plans in 2022.

We provide certain postretirement health care, dental, and life insurance benefits for eligible employees (the “postretirement benefit plan”). We contributed $1 million, $7 million, and $8 million to the postretirement benefit plan in 2023, 2022, and 2021, respectively. We expect to contribute $2 million to the postretirement benefit plan in 2024.

Net periodic benefit costs by component for the pension plans and postretirement benefit plan were as follows:

	Pension Plans						Postretirement Benefit Plan
	Year Ended December 31,						Year Ended December 31,
(In millions of USD)	2023		2022		2021		2023		2022		2021

The unrecognized amounts that otherwise would have been charged and/or credited to AOCI in accordance with the GAAP guidance on accounting for retirement benefits are recorded as a regulatory asset or regulatory liability on our consolidated statements of financial position, as discussed in Note 7. The amounts recorded as a regulatory asset or regulatory liability represent a net periodic benefit cost or credit to be recognized in our operating income in future periods. Our measurement of the accumulated benefit obligation for the postretirement benefit plan as of December 31, 2023 and December 31, 2022 reflects anticipated future receipts of subsidies under the Medicare Prescription Drug, Improvement and Modernization Act of 2003, which

we have applied for beginning in 2023. The initial reflection of the subsidy as of December 31, 2022 resulted in a reduction in the accumulated postretirement benefit obligation of $7 million related to benefits attributed to past services.

The net actuarial loss for the year ended December 31, 2023 within the change in benefit obligation for the pension plans is primarily the result of decreases in the discount rates and increases in the rate of salary increases and the interest crediting rate. The net actuarial gains for the year ended December 31, 2022 within the change in benefit obligation for both the pension plans and postretirement benefit plan are primarily the result of increases in the discount rates.

The combined projected benefit obligation and fair value of plan assets for those plans in which the projected benefit obligation is in excess of the fair value of plan assets are as follows:

	Pension Plans
	December 31,
(In millions of USD)	2023		2022

Investment Objectives and Fair Value Measurement

The general investment objectives of the retirement plan and postretirement benefit plan include maximizing the return within reasonable and prudent levels of risk and controlling administrative and management costs. Investment decisions are made by our retirement benefits board as delegated by our board of directors. Equity investments may include various types of U.S. and international equity securities, such as large-cap, mid-cap, and small-cap stocks. Fixed income investments may include cash and short-term instruments, U.S. Government securities, corporate bonds, mortgages, and other fixed income investments. No investments are prohibited for use in the retirement plan or postretirement benefit plan, including derivatives, but our exposure to derivatives currently is not material. We intend that the long-term capital growth of the retirement and postretirement benefit plans, together with employer contributions, will provide for the payment of the benefit obligations.

As of December 31, 2023 and 2022, the plan assets of the retirement plan and postretirement benefit plan consisted of the following assets by category:

	Target Allocation		Pension Plans				Postretirement Benefit Plan
Asset Category	2023		2023		2022		2023		2022
Fixed income securities	50	%	50	%	50	%	50	%	50	%
Equity securities	50	%	50	%	50	%	50	%	50	%
Total	100	%	100	%	100	%	100	%	100	%

We determine our expected long-term rate of return on plan assets based on the current and expected target allocations of the retirement plan and postretirement benefit plan investments and considering historical and expected long-term rates of return on comparable fixed income investments and equity investments.

The measurement of fair value is based on a three-tier hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs, such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore, requiring an entity to develop its own assumptions. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. For the years ended December 31, 2023 and 2022, there were no transfers between levels.

For the years ended December 31, 2023 and 2022, the fair value of retirement plan and postretirement benefit plan assets measured on a recurring basis at the Level 1 tier were as follows:

	Pension Plans				Postretirement Benefit Plan
	December 31,				December 31,
(In millions of USD)	2023		2022		2023		2022
Mutual funds — U.S. equity securities	$	42	$	38	$	68	$	59
Mutual funds — international equity securities	11		10		3		3
Mutual funds — fixed income securities	52		48		70		61
Total	$	105	$	96	$	141	$	123

The mutual funds consist primarily of publicly traded mutual funds and are recorded at fair value based on observable trades for identical securities in an active market.

Defined Contribution Plan

We also sponsor a defined contribution retirement savings plan. Participation in this plan is available to substantially all employees. We match employee contributions up to certain predefined limits based upon eligible compensation and the employee’s contribution rate. The cost of this plan was $7 million, $7 million, and $6 million for the years ended December 31, 2023, 2022, and 2021, respectively.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

The measurement of fair value is based on a three-tier hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. For the years ended December 31, 2023 and 2022, there were no transfers between levels.

Our assets measured at fair value subject to the three-tier hierarchy at December 31, 2023, were as follows:

	Fair Value Measurements at Reporting Date Using
	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
(In millions of USD)	(Level 1)		(Level 2)		(Level 3)
Financial assets measured on a recurring basis:
Mutual funds — fixed income securities	$	44	$	—	$	—
Mutual funds — equity securities	14		—		—

Mutual funds — equity securities	11		—		—
Total	$	55	$	—	$	—

As of December 31, 2023 and 2022, we held certain assets that are required to be measured at fair value on a recurring basis. The assets consist of investments recorded within cash and cash equivalents and other long-term assets, including investments held in a trust associated with our supplemental benefit plans described in Note 11 and certain deferred compensation plan investments. The mutual funds we own are publicly traded and are recorded at fair value based on observable trades for identical securities in an active market. Changes in the observed trading prices and liquidity of money market funds are monitored as additional support for determining fair value.

We also held non-financial assets that are required to be measured at fair value on a non-recurring basis. These consist of goodwill and intangible assets. We did not record any impairment charges on long-lived assets and no other significant events occurred requiring non-financial assets and liabilities to be measured at fair value (subsequent to initial recognition) during the years ended December 31, 2023 and 2022.

Fair Value of Financial Assets and Liabilities

Fixed Rate Debt

Based on the borrowing rates obtained from third party lending institutions currently available for bank loans with similar terms and average maturities from active markets, the fair value of our consolidated long-term debt and debt maturing within one year, excluding revolving credit agreements and commercial paper, was $6,660 million and $5,849 million at December 31, 2023 and 2022, respectively. These fair values represent Level 2 under the three-tier hierarchy described above. The total book value of our consolidated long-term debt and debt maturing within one year, net of discount and deferred financing fees and excluding revolving credit agreements and commercial paper, was $7,287 million and $6,649 million at December 31, 2023 and 2022, respectively.

Revolving Credit Agreements

At December 31, 2023 and 2022, we had a consolidated total of $311 million and $208 million, respectively, outstanding under our revolving credit agreements, which are variable rate loans. The fair value of these loans approximates book value based on the borrowing rates currently available for variable rate loans obtained from third party lending institutions. These fair values represent Level 2 under the three-tier hierarchy described above. See Note 9 for changes to our revolving credit agreements since December 31, 2022.

Other Financial Instruments

The carrying value of other financial instruments included in current assets and current liabilities, including cash and cash equivalents, special deposits and commercial paper, approximates their fair value due to the short-term nature of these instruments.

Dec. 31, 2023

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENT LIABILITIES

COMMITMENTS AND CONTINGENT LIABILITIES

Environmental Matters

We are subject to federal, state and local environmental laws and regulations, which impose limitations on the discharge of pollutants into the environment, require reporting of emissions from certain equipment, establish standards for the management, treatment, storage, transportation and disposal of hazardous materials and of solid and hazardous wastes, and impose obligations to investigate and remediate contamination in certain circumstances. Liabilities relating to investigation and remediation of contamination, as well as other liabilities concerning hazardous materials or contamination, such as claims for personal injury or property damage, may arise at many locations, including formerly owned or operated properties and sites where wastes have been treated or disposed of, as well as properties currently owned or operated by us. Such liabilities may arise even where the contamination does not result from noncompliance with applicable environmental laws. Under some environmental laws, such liabilities may also be joint and several, meaning that a party can be held responsible for more than its share of the liability involved, or even the entire share. Although environmental requirements generally have become more stringent and compliance with those requirements more expensive, we are not aware of any specific developments that would increase our costs for such compliance in a manner that would be expected to have a material adverse effect on our financial condition, results of operations or liquidity.

Our assets and operations also involve the use of materials classified as hazardous, toxic or otherwise dangerous. Some of the properties that we own or operate have been used for many years and include older facilities and equipment that may be more likely than newer ones to contain or be made from such materials. Some of these properties include above ground or underground storage tanks and associated piping. Some of them also include large electrical equipment filled with mineral oil, which may contain or previously have contained PCBs. Some of our facilities and electrical equipment may also contain asbestos containing materials. Our facilities and equipment are often situated close to or on property owned by others so that, if they are the source of contamination, the property of others may be affected. For example, above ground and underground transmission lines sometimes traverse properties that we do not own and transmission assets that we own or operate are sometimes commingled at our transmission stations with distribution assets owned or operated by our transmission customers.

Some properties in which we have an ownership interest or at which we operate are, or are suspected of being, affected by environmental contamination. We are not aware of any pending or threatened claims against us with respect to environmental contamination relating to these properties, or of any investigation or remediation of contamination at these properties, that entail costs likely to materially affect us. Some facilities and properties are located near environmentally sensitive areas, including wetlands and habitat for threatened and endangered species.

Litigation

We are involved in certain legal proceedings before various courts, governmental agencies and mediation panels concerning matters arising in the ordinary course of business. These proceedings include certain contract disputes, eminent domain and vegetation management activities, regulatory matters and pending judicial matters. We cannot predict the final disposition of such proceedings. We regularly review legal matters and record provisions for claims that are considered probable of loss.

Rate of Return on Equity Complaints

Two complaints were filed with the FERC by combinations of consumer advocates, consumer groups, municipal parties and other parties challenging the base ROE in MISO. The complaints were filed with the FERC under Section 206 of the FPA requesting that the FERC find the MISO regional base ROE rate (the “base ROE”) for all MISO TO’s, including our MISO Regulated Operating Subsidiaries, to no longer be just and reasonable.

Initial Complaint

On November 12, 2013, the Association of Businesses Advocating Tariff Equity, Coalition of MISO Transmission Customers, Illinois Industrial Energy Consumers, Indiana Industrial Energy Consumers, Inc., Minnesota Large Industrial Group and Wisconsin Industrial Energy Group (collectively, the “complainants”) filed the Initial Complaint with the FERC. The complainants sought a FERC order to reduce the base ROE used in

the formula transmission rates for our MISO Regulated Operating Subsidiaries to 9.15%, reducing the equity component of our capital structure and terminating the ROE adders approved for certain MISO Regulated Operating Subsidiaries. The FERC set the base ROE for hearing and settlement procedures, while denying all other aspects of the Initial Complaint. The ROE collected through the MISO Regulated Operating Subsidiaries’ rates during the period November 12, 2013 through September 27, 2016 consisted of a base ROE of 12.38% plus applicable incentive adders.

Second Complaint

On February 12, 2015, the Second Complaint was filed with the FERC by Arkansas Electric Cooperative Corporation, Mississippi Delta Energy Agency, Clarksdale Public Utilities Commission, Public Service Commission of Yazoo City and Hoosier Energy Rural Electric Cooperative, Inc., seeking a FERC order to reduce the base ROE used in the formula transmission rates of our MISO Regulated Operating Subsidiaries to 8.67%, with an effective date of February 12, 2015.

On June 30, 2016, the presiding ALJ issued an initial decision that recommended a base ROE of 9.70% for the refund period from February 12, 2015 through May 11, 2016, with a maximum ROE of 10.68%, which also would be applicable going forward from the date of a final FERC order. The Second Complaint was dismissed as a result of an order issued by the FERC on November 21, 2019 and the dismissal of the complaint was reaffirmed in the May 2020 Order.

FERC Orders

Since the filing of the Initial Complaint, the FERC has issued separate orders in these proceedings on September 28, 2016, November 21, 2019 and May 21, 2020. These orders resulted in multiple revisions to the base ROE and refund settlements. The MISO TOs, along with our MISO Regulated Operating Subsidiaries, and other various parties have challenged certain aspects of these orders through requests for rehearing. In the most recent order, the FERC determined that a methodology using three financial models should be used to determine the base ROE. By applying the new methodology, the FERC determined that the base ROE for the Initial Complaint should be 10.02% and the top of the range of reasonableness for that period should be 12.62%. The FERC determined that this base ROE should apply during the first refund period of November 12, 2013 to February 11, 2015 and from the date of the order issued by the FERC on September 28, 2016 prospectively. The FERC ordered refunds to be made in accordance with the May 2020 Order. Refund settlements were finalized by March 31, 2022, and during the year ended December 31, 2022, we received net settlement payments of less than $1 million owed from customers.

August 2022 D.C. Circuit Court Decision

On August 9, 2022, in response to appeals of the FERC's orders on the MISO ROE Complaints, the D.C. Circuit Court issued an opinion that rejected the FERC’s use of a risk premium model in the methodology used to determine the revised base ROE for MISO TOs. The D.C. Circuit Court decision vacated the FERC’s orders on the MISO ROE Complaints, dismissed the remaining outstanding appeals of these orders and remanded the matter to the FERC for further proceedings.

It is possible that the base ROE established in the May 2020 Order may be revised and that we could be required to provide additional material refunds upon resolution of the proceedings. We are awaiting action by the FERC in these proceedings to provide further insight into possible changes to our base ROE and the periods for which a revised ROE applies. We cannot predict whether these proceedings will have a material impact, or estimate the possible impact, on our financial condition, results of operations or cash flows.

See Note 6 for a summary of our base ROE and incentive adders for transmission rates. As of December 31, 2023, our MISO Regulated Operating Subsidiaries had a total of approximately $5 billion of equity in their collective capital structures for ratemaking purposes. Based on this level of aggregate equity, we estimate that each 10 basis point change in the authorized ROE would impact annual consolidated net income by approximately $5 million.

Purchase Obligations

At December 31, 2023, we had purchase obligations of $115 million representing commitments for materials, services and equipment that had not been received as of December 31, 2023, primarily for construction and maintenance projects for which we have an executed contract. Of these purchase obligations, $99 million is

expected to be paid in 2024, with the majority of the items related to materials and equipment that have long production lead times.

Other Commitments

METC

Amended and Restated Purchase and Sale Agreement for Ancillary Services. Since METC does not own any generating facilities, it must procure ancillary services from third party suppliers, such as Consumers Energy. Currently, under the Ancillary Services Agreement, METC pays Consumers Energy for providing certain generation-based services necessary to support the reliable operation of the bulk power grid, such as voltage support and generation capability and capacity to balance loads and generation.

Amended and Restated Easement Agreement. Under the Easement Agreement, Consumers Energy provides METC with an easement to the land on which a majority of METC’s transmission towers, poles, lines and other transmission facilities used to transmit electricity for Consumers Energy and others are located. The term of the Easement Agreement runs through December 31, 2050 and is subject to 10 automatic 50-year renewals thereafter unless METC gives notice of nonrenewal at least one year in advance. METC pays Consumers Energy $10 million in annual rent per year for the easement and also pays for any rentals, property, taxes, and other fees related to the property covered by the Easement Agreement. Payments to Consumers Energy under the Easement Agreement are charged to operation and maintenance expense in our consolidated statements of comprehensive income.

ITC Midwest

Operations Services Agreement For 34.5 kV Transmission Facilities. ITC Midwest and IP&L entered into the OSA under which IP&L performs certain operations functions for ITC Midwest’s 34.5 kV transmission system.

ITC Great Plains

Amended and Restated Maintenance Agreement. Sunflower and ITC Great Plains have entered into the Sunflower Agreement pursuant to which Sunflower has agreed to perform various field operations and maintenance services related to certain ITC Great Plains assets.

Concentration of Credit Risk

Our credit risk is primarily with DTE Electric, Consumers Energy and IP&L, which were responsible for approximately 21.7%, 21.3% and 24.5%, respectively, or $338 million, $332 million and $382 million, respectively, of our consolidated billed revenues for the year ended December 31, 2023. This portion of total billed revenues of DTE Electric, Consumers Energy and IP&L include the refund of 2021 revenue accruals and deferrals and exclude any amounts for the 2023 revenue accruals and deferrals that were included in our 2023 operating revenues but will not be billed to our customers until 2025. Under DTE Electric’s and Consumers Energy’s current rate structure, DTE Electric and Consumers Energy include in their retail rates the actual cost of transmission services provided by ITCTransmission and METC, respectively, in their billings to their customers, effectively passing through to end-use consumers the total cost of transmission service. IP&L currently includes in their retail rates an allowance for transmission services provided by ITC Midwest in their billings to their customers. However, any financial difficulties experienced by DTE Electric, Consumers Energy or IP&L may affect their ability to make payments for transmission service to ITCTransmission, METC, and ITC Midwest, which could negatively impact our business. MISO, as our MISO Regulated Operating Subsidiaries’ billing agent, bills DTE Electric, Consumers Energy, IP&L and other customers on a monthly basis and collects fees for the use of the MISO Regulated Operating Subsidiaries’ transmission systems. SPP is the billing agent for ITC Great Plains and bills transmission customers for the use of ITC Great Plains transmission systems. MISO and SPP have implemented strict credit policies for its members’ customers, which include customers using our transmission systems. Specifically, MISO and SPP require a letter of credit or cash deposit equal to the credit exposure, which is determined by a credit scoring model and other factors, from any customer using a member’s transmission system.

Segment Reporting [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

We identify reportable segments based on the criteria set forth by the FASB regarding disclosures about segments of an enterprise, including the regulatory environment of our subsidiaries and the business activities performed to earn revenues and incur expenses.

Regulated Operating Subsidiaries

We aggregate our Regulated Operating Subsidiaries into one reportable operating segment based on their similar regulatory environment and economic characteristics, among other factors. They are engaged in the transmission of electricity within the United States, earn revenues from the same types of customers and are regulated by the FERC.

ITC Holdings and Other

Information below for ITC Holdings and Other consists primarily of a holding company whose activities include debt financings and general corporate activities. The other subsidiaries of ITC Holdings, excluding the Regulated Operating Subsidiaries, do not have significant operations.

GENERAL

For ITC Holdings Corp.’s (“ITC Holdings,” “we,” “our” and “us”) presentation (parent company only), the investment in subsidiaries is accounted for using the equity method. The condensed parent company financial statements and notes should be read in conjunction with the consolidated financial statements and notes of ITC Holdings appearing in this Annual Report on Form 10-K.

As a holding company with no business operations, ITC Holdings’ assets consist primarily of investments in our subsidiaries. ITC Holdings’ material cash inflows are only from dividends and other payments received from our subsidiaries, the proceeds raised from the sale of debt securities, issuances under our commercial paper program and borrowings under our Revolving Credit Agreement. ITC Holdings may not be able to access cash generated by our subsidiaries in order to fulfill cash commitments. The ability of our subsidiaries to make dividend and other payments to us is subject to the availability of funds after taking into account their respective funding requirements, the terms of their respective indebtedness, the regulations of the FERC under the FPA and applicable state laws. In addition, there are practical limitations on using the net assets of each of our Regulated Operating Subsidiaries as of December 31, 2023 for dividends based on management's intent to maintain the FERC-approved capital structure targeting 60% equity and 40% debt for each of our Regulated Operating Subsidiaries. These net assets are included in Schedule I as the line-item “Investments in subsidiaries.” Each of our subsidiaries, however, is legally distinct from us and has no obligation, contingent or otherwise, to make funds available to us.

DEBT

As of December 31, 2023, the maturities of our debt outstanding were as follows:

(In millions of USD)
2024	$	400
2025	—
2026	400
2027	1,400
2028	—
2029 and thereafter	1,700
Total	$	3,900

Refer to Note 9 to the consolidated financial statements for additional information on the ITC Holdings Senior Notes, the ITC Holdings Revolving Credit Agreement, the ITC Holdings commercial paper program and the ITC Holdings derivative instruments and hedging activities.

Fixed Rate Debt

Based on the borrowing rates obtained from third party lending institutions currently available for bank loans with similar terms and average maturities from active markets, the fair value of the ITC Holdings Senior Notes was $3,792 million and $3,132 million at December 31, 2023 and 2022, respectively. The total book value of the ITC Holdings Senior Notes, net of discount and deferred financing fees, was $3,878 million and $3,331 million at December 31, 2023 and 2022, respectively. The fair values of the ITC Holdings Senior Notes represent Level 2 under the three-tier hierarchy described in Note 12 to the consolidated financial statements.

Revolving Credit Agreements

At December 31, 2023, we did not have a balance outstanding under our Revolving Credit Agreement. As of December 31, 2022 we had $10 million outstanding under our revolving credit agreements, which are variable rate loans. The fair value of these loans approximates book value based on the borrowing rates currently available for variable rate loans obtained from third party lending institutions. The fair values of the revolving

credit agreements represent Level 2 under the three-tier hierarchy described in Note 12 to the consolidated financial statements.

Other Financial Instruments

The carrying value of other financial instruments included in current assets and current liabilities, including cash and cash equivalents, special deposits and commercial paper, approximates their fair value due to the short-term nature of these instruments.

RELATED PARTY TRANSACTIONS

Related Party Receivables and Payables

We may incur charges from our subsidiaries for general corporate expenses incurred. In addition, we may perform additional services for, or receive additional services from our subsidiaries. These transactions are in the normal course of business and payments for these services are settled through accounts receivable and accounts payable, as necessary. We generally settle our intercompany balances with our affiliates on a net basis monthly.

Retirement Benefits

We are the plan sponsor for a pension plan, other postretirement plans and a defined contribution plan. The benefits-related expenses recorded by our affiliates result from the inclusion of benefit costs as a component of the total charge for services performed by our employees under the cost assignment and allocation methods used by us and our subsidiaries.

Intercompany Tax Sharing Arrangement

We file consolidated income tax returns that include our affiliates, which are taxed as a corporation for federal and Michigan income tax purposes. We operate under an intercompany tax sharing arrangement with our subsidiaries and as a result may receive or pay federal and state income tax based on their stand-alone company tax positions.

____________________________

(a)The net income tax payments were pursuant to intercompany tax sharing arrangements, and the total of these tax payments is presented as a net cash outflow or inflow from operating activities in the condensed parent company statements of cash flows. Other reconciling items between the parent company and the consolidated tax liabilities are presented as deferred and other income taxes in the adjustments to reconcile net income to net cash provided by operating activities. Additionally, ITC Holdings paid its subsidiaries for NOLs utilized by the consolidated group.

Intercompany Loan Agreement

On September 21, 2020, we advanced an intercompany loan to ITCTransmission totaling $50 million, due September 21, 2022. On January 14, 2022, ITCTransmission repaid the intercompany loan in full with proceeds from the issuance of First Mortgage Bonds on January 14, 2022. We received interest payments of less than $1 million and $1 million during the years ended December 31, 2022 and 2021, respectively, from ITCTransmission associated with this intercompany loan.

Additionally, at December 31, 2022 we had a $4 million intercompany loan with a subsidiary, due June 1, 2046. On June 1, 2023, the subsidiary repaid the intercompany loan in full. We received principal and interest payments of $4 million, less than $1 million and $1 million for the years ended December 31, 2023, 2022 and 2021, respectively, from the subsidiary associated with this intercompany loan.

SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2023

Accounting Policies [Abstract]

Principles of Consolidation

ITC Holdings consolidates its majority owned subsidiaries. We eliminate all intercompany balances and transactions.

Use of Estimates

The preparation of the consolidated financial statements requires us to use estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results may differ from our estimates.

Regulation

Our Regulated Operating Subsidiaries are subject to the regulatory jurisdiction of the FERC, which issues orders pertaining to rates, recovery of certain costs, including the costs of

transmission assets and regulatory assets, conditions of service, accounting, financing authorization and operating-related matters. The utility operations of our Regulated Operating Subsidiaries meet the accounting standards set forth by the FASB for the accounting effects of certain types of regulation. These accounting standards recognize the cost-based rate setting process, which results in differences in the application of GAAP between regulated and non-regulated businesses. These standards require the recording of regulatory assets and liabilities for certain transactions that would have been recorded in the statements of comprehensive income in non-regulated businesses. Regulatory assets represent costs that will be included as a component of future tariff rates and regulatory liabilities represent amounts provided in the current tariff rates that are intended to recover costs expected to be incurred in the future or amounts to be refunded to customers.

Cash and Cash Equivalents and Restricted Cash and Cash Equivalents

We consider all unrestricted highly-liquid temporary investments with an original maturity of three months or less at the date of purchase to be cash equivalents.

Restricted Cash — Restricted cash includes cash that is legally or contractually restricted for use or withdrawal or are formally set aside for a specific purpose. Restricted cash primarily represents cash on deposit to pay for vegetation management, land easements and land purchases for the purpose of transmission line construction as well as amounts liquidated to make benefit payments related to our supplemental benefit plans.

Inventories

Materials and supplies inventories are valued at average cost. Additionally, the costs of warehousing activities are recorded here and included in the cost of materials when requisitioned.

Property, Plant and Equipment

Property, plant and equipment in service at our Regulated Operating Subsidiaries is stated at its original cost when first devoted to utility service. The gross book value of assets retired less salvage proceeds is charged to accumulated depreciation. The provision for depreciation of transmission assets is a significant component of our Regulated Operating Subsidiaries’ cost of service under FERC-approved rates. Periodically, we perform depreciation studies of the assets at our Regulated Operating Subsidiaries. The results of these studies are submitted to and require approval from the FERC prior to changing our depreciation rates. Depreciation is computed over the estimated useful lives of the assets using the straight-line method for financial reporting purposes and accelerated methods for income tax reporting purposes. The composite depreciation rate for our Regulated Operating Subsidiaries included in our consolidated statements of comprehensive income was 2.4% for each of the years ended December 31, 2023 and 2022 and 2.0% for the year ended December 31, 2021. The composite depreciation rates include depreciation primarily on transmission station equipment, towers, poles and overhead and underground lines that have a useful life ranging from 43 to 70 years. The portion of depreciation expense related to asset removal costs is added to regulatory liabilities or deducted from regulatory assets and removal costs incurred are deducted from regulatory liabilities or added to regulatory assets. Certain of our Regulated Operating Subsidiaries capitalize to property, plant and equipment AFUDC in accordance with FERC regulations. AFUDC represents the composite cost incurred to fund the construction of assets, including interest expense and a return on equity capital devoted to construction of assets. The interest component of AFUDC was a reduction to interest expense of $11 million, $9 million and $8 million for the years ended December 31, 2023, 2022 and 2021, respectively.

For acquisitions of property, plant and equipment greater than the net book value (other than asset acquisitions accounted for under the purchase method of accounting that result in goodwill), the acquisition premium is recorded to property, plant and equipment and amortized over the estimated remaining useful lives of the assets using the straight-line method for financial reporting purposes and accelerated methods for income tax reporting purposes.

Property, plant and equipment includes capital equipment stated at original cost consisting of items that are expected to be used exclusively for capital projects.

Property, plant and equipment at our non-regulated subsidiaries is stated at its acquired cost. Proceeds from salvage less the net book value of the disposed assets is recognized as a gain or loss on disposal. Depreciation is computed based on the acquired cost less expected residual value and is

recognized over the estimated useful lives of the assets on a straight-line method for financial reporting purposes and accelerated methods for income tax reporting purposes.

General Interconnection Projects and Contributions in Aid of Construction

Certain capital investment at our Regulated Operating Subsidiaries relates to investments made under GIAs. The GIAs typically consist of both transmission network upgrades, which are a category of upgrades deemed by the FERC to benefit the transmission system as a whole, as well as direct connection facilities, which are necessary to interconnect the generating facility to the transmission system and primarily benefit the generating facility. GIAs typically require the generator to make a contribution in aid of construction to our Regulated Operating Subsidiaries to cover the cost of certain investments made by us as part of the agreement. However, we may fund construction of certain projects without contributions from the generators.

Our investments in transmission facilities are recorded to property, plant and equipment, and are recorded net of any contribution in aid of construction. We also receive refundable deposits from the generator for certain investment in network upgrade facilities in advance of construction, which are recorded to current or non-current liabilities depending on the expected refund date.

Jointly Owned Utility Plant/Coordinated Services — Certain of our Regulated Operating Subsidiaries have agreements with other utilities for the joint ownership of assets as described in Note 15. We account for these jointly owned assets by recording property, plant and equipment for the percentage of our undivided ownership interest. Various agreements provide the authority for construction of capital improvements and the operating costs associated with the substations and lines. Generally, each party is responsible for the capital, operation and maintenance, and other costs of these jointly owned facilities based upon each participant’s undivided ownership interest, and each participant is responsible for providing its own financing. Our participating share of expenses associated with these jointly held assets is primarily recorded within operation and maintenance expense on our consolidated statements of comprehensive income.

Available-For-Sale Securities

We have certain investments in mutual funds, including fixed income securities and equity securities, that are classified as fair value through net income. The investments fund our two supplemental nonqualified, noncontributory retirement benefit plans for selected management employees as described in Note 11, as well as other deferred compensation plans. Gains and losses associated with these investments are recorded in other expenses (income), net in the consolidated statements of comprehensive income.

Impairment of Long-Lived Assets

Other than goodwill, our long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If the carrying amount of the asset exceeds the expected undiscounted future cash flows generated by the asset, the asset is written down to its estimated fair value and an impairment loss is recognized in our consolidated statements of comprehensive income.

Goodwill and Intangible Assets, Goodwill, Policy

Goodwill is not subject to amortization; however, goodwill is required to be assessed for impairment, and a resulting write-down, if any, is to be reflected in operating expense. We have goodwill recorded relating to our acquisitions of ITCTransmission and METC, and ITC Midwest’s acquisition of the IP&L transmission assets. Goodwill is reviewed at the reporting unit level at least annually for impairment and whenever facts or circumstances indicate that the value of goodwill may be impaired. Our reporting units are ITCTransmission, METC and ITC Midwest as each entity represents an individual operating segment to which goodwill has been assigned. At December 31, 2023 and 2022, we had goodwill balances recorded at ITCTransmission, METC and ITC Midwest of $173 million, $454 million and $323 million, respectively.

In order to perform an impairment analysis, we have the option of performing a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, in which case no further testing is required. If an entity bypasses the qualitative assessment or performs a qualitative assessment but determines that it is more likely than not that a reporting unit’s fair value is less than its carrying amount, a quantitative, fair value-based test is performed to assess and measure goodwill impairment, if any. If a quantitative assessment is performed, we determine the fair value of our reporting

units using valuation techniques based on discounted future cash flows under various scenarios and consider estimates of market-based valuation multiples for companies within the peer group of our reporting units.

We completed our annual goodwill impairment test for our reporting units as of October 1, 2023 and determined that no impairment exists. There were no events subsequent to October 1, 2023 that indicated impairment of our goodwill.

Deferred Financing Fees and Discount or Premium On Debt

Costs related to the issuance of long-term debt are generally recorded as a direct deduction from the carrying amount of the related debt and amortized over the life of the debt. Debt issuance costs incurred prior to the associated debt funding are presented as an asset. Unamortized debt issuance costs associated with the revolving credit agreements, commercial paper and other similar arrangements are presented as an asset (regardless of whether there are any amounts outstanding under those credit facilities) and amortized over the life of the particular arrangement. The debt discount or premium related to the issuance of long-term debt is recorded to long-term debt and amortized over the life of the debt. We recorded $6 million for each of the years ended December 31, 2023 and 2022 and $5 million for the year ended December 31, 2021 to interest expense for the amortization of deferred financing fees and debt discounts.

Asset Retirement Obligations

A conditional asset retirement obligation is a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within our control. We have identified conditional asset retirement obligations primarily associated with the removal of equipment containing PCBs and asbestos. We record a liability at fair value for a legal asset retirement obligation in the period in which it is incurred. When a new legal obligation is recorded, we capitalize the costs of the liability by increasing the carrying amount of the related long-lived asset. We accrete the liability to its present value each period and depreciate the capitalized cost over the useful life of the related asset. At the end of the asset’s useful life, we settle the obligation for its recorded amount. We recognize regulatory assets for the timing differences between the incurred costs to settle our legal asset retirement obligations and the recognition of such obligations as applicable for our Regulated Operating Subsidiaries. Our asset retirement obligations of $5 million as of December 31, 2023 and 2022 are included in other liabilities.

Financial Instruments

We may use derivative financial instruments to manage our exposure to fluctuations in interest rates. For derivative instruments that have been designated and qualify as cash flow hedges of the exposure to variability in expected future cash flows, the unrealized gain or loss on the derivative is initially reported, net of tax, as a component of other comprehensive income (loss) and reclassified to the consolidated statements of comprehensive income when the underlying hedged transaction affects net income. Cash flows related to derivative instruments that are designated in hedging relationships are generally classified on the consolidated statements of cash flows within cash flows from operating activities. The fair values of derivatives are recognized as current or long-term assets and liabilities depending on the timing of settlements and resulting cash flows. Refer to Note 9 for additional discussion regarding derivative instruments.

Contingent Obligations

We are subject to a number of federal and state laws and regulations, as well as other factors and conditions that potentially subject us to environmental, litigation, income tax and other contingencies. We periodically evaluate our exposure to such contingencies and record liabilities for those matters where a loss is considered probable and reasonably estimable. We reverse the liabilities recorded for those matters when a loss is no longer considered probable or the liabilities are otherwise settled. Our liabilities exclude any estimates for legal costs not yet incurred associated with handling these matters, which could be material. The adequacy of liabilities recorded can be significantly affected by external events or conditions that can be unpredictable; thus, the ultimate outcome of such matters could materially affect our consolidated financial statements.

Revenues

Substantially all of our revenue from contracts with customers is generated from providing transmission services to customers as services are provided based on our FERC-approved cost-based Formula Rates. We record a reserve for revenue subject to refund when such refund is probable and can be reasonably estimated. This reserve is recorded as a reduction to operating revenues.

The cost-based Formula Rates at our Regulated Operating Subsidiaries include a true-up mechanism that compares the actual revenue requirements of our Regulated Operating Subsidiaries to their billed revenues for each year to determine any over- or under-collection of revenue requirements and we record a revenue deferral or accrual for the difference. The true-up mechanisms under our Formula Rates are considered alternative revenue programs of rate-regulated utilities. Operating revenues arising from these alternative revenue programs are presented on our consolidated statements of comprehensive income in the line “Formula Rate true-up”, which is separate from the reporting of our tariff revenues, which are presented in the line “Transmission and other services.” Only the initial origination of our alternative revenue program revenue is reported in the Formula Rate true-up line on our consolidated statements of comprehensive income. When those amounts are subsequently included in the price of utility service and billed or refunded to customers, we account for that event as the recovery or settlement of the associated regulatory asset or regulatory liability, respectively. Refer to Note 6 under “Cost-Based Formula Rates with True-Up Mechanism” and Note 4 under “Formula Rate True-Up” for a discussion of our revenue accounting under our cost-based Formula Rates.

Transmission Services

Through our Regulated Operating Subsidiaries, we generate nearly all our revenue from providing electric transmission services over our transmission systems. As independent transmission companies, our transmission services are provided and revenues are received based on our tariffs, as approved by the FERC. We recognize revenue for transmission services over time as transmission services are provided to customers (generally using an output measure of progress based on transmission load delivered). Customers simultaneously receive and consume the benefits provided by the Regulated Operating Subsidiaries’ services. We recognize revenue in the amount to which we have the right to invoice because we have a right to consideration in an amount that corresponds directly with the value to the customer of performance completed to date. As billing agents, MISO and SPP independently bill our customers on a monthly basis and collect fees for the use of our transmission systems. No component of the transaction price is allocated to unsatisfied performance obligations.

Transmission service revenue includes an estimate for unbilled revenues from service that has been provided but not billed by the end of an accounting period. Unbilled revenues are dependent upon a number of factors that require management’s judgment including estimates of transmission network load (for the MISO Regulated Operating Subsidiaries) and preliminary information provided by billing agents. Due to the seasonal fluctuations of actual load, the unbilled revenue amount generally increases during the spring and summer and decreases during the fall and winter. See Note 5 for information on changes in unbilled accounts receivable.

Other Services

Other services revenue consists of rental revenues, easement revenues and amounts from providing ancillary services. A portion of other services revenue is treated as a revenue credit and reduces gross revenue requirement when calculating net revenue requirement under our Formula Rates. Total other services revenue was $6 million for each of the years ended December 31, 2023, 2022 and 2021.

Formula Rate True-Up

The true-up mechanism under our Formula Rates is considered an alternative revenue program of a rate-regulated utility given it permits our Regulated Operating Subsidiaries to adjust future rates in response to past activities or completed events in order to collect our actual revenue requirements under our Formula Rates. In accordance with our accounting policy, only the current year origination of the true-up is reported as a Formula Rate true-up. See “Cost-Based Formula Rates with True-Up Mechanism” in Note 6 for more information on our Formula Rates.

Share-based Payment and Employee Share Purchase Plan

Under long-term incentive plans, we grant long-term incentive awards consisting of PBUs and SBUs to employees, including executive officers, of ITC Holdings. Generally, each PBU and SBU granted is valued based on one share of Fortis common stock traded on the Toronto Stock Exchange, converted to U.S. dollars and settled only in cash. However, certain SBUs granted to the executives may settle in cash, 100% Fortis common stock, or 50% cash and 50% Fortis common stock depending on executives’ settlement elections and whether certain share ownership requirements are met. All PBUs and SBUs are classified as liability awards and generally vest on the third January 1st following the grant date, provided the service and performance criteria, as applicable, are satisfied, and will be settled during the subsequent quarter. However, certain awards may vest over a shorter period or on the grant date if certain retirement eligibility criteria are met. The PBUs and SBUs earn dividend equivalents, which are also re-measured and settled consistent with the target award at the end of the vesting period. The granted awards and related dividend equivalents have no shareholder rights.

Compensation cost is recognized over the expected vesting period and remeasured each reporting period based on Fortis’ stock price. The PBUs are also remeasured each reporting period based on the applicable market and performance conditions in the awards. Compensation cost is adjusted for forfeitures in the period in which they occur and the final measure of compensation cost for the awards is based on the cash settlement amount.

Comprehensive Income (Loss)

Comprehensive income (loss) is the change in stockholder’s equity during a period arising from transactions and events from non-owner sources, including net income and any gain or loss arising from derivative financial instruments.

Income Taxes

Deferred income taxes are recognized for the expected future tax consequences of events that have been recognized in the consolidated financial statements or tax returns. Deferred income tax assets and liabilities are determined based on the differences between the financial statements and the tax bases of various assets and liabilities, using the tax rates expected to be in effect for the year in which the differences are expected to reverse, and classified as non-current in our consolidated statements of financial position.

The accounting standards for uncertainty in income taxes prescribe a recognition threshold and a measurement attribute for tax positions taken, or expected to be taken, in a tax return that may not be sustainable. As of December 31, 2023, we have not recognized any uncertain income tax positions.

We file our federal and Michigan income tax returns as part of the FortisUS consolidated tax returns and we are a party to an intercompany tax sharing agreement that establishes the method for determining tax liabilities that are due and allocating tax attributes that are utilized on the consolidated income tax returns. We continue to file with various other state and city jurisdictions where we have a separate return filing obligation. Our prior consolidated federal tax returns are no longer subject to U.S. federal tax examinations for tax years 2019 and earlier. State and city jurisdictions that remain subject to examination range from tax years 2019 to 2022. In the event we are assessed interest or penalties by any income tax jurisdictions, interest and penalties would be recorded as interest expense and other expenses,

respectively, in our consolidated statements of comprehensive income.

Revenue from Contract with Customer [Abstract]

Revenues

Substantially all of our revenue from contracts with customers is generated from providing transmission services to customers as services are provided based on our FERC-approved cost-based Formula Rates. We record a reserve for revenue subject to refund when such refund is probable and can be reasonably estimated. This reserve is recorded as a reduction to operating revenues.

The cost-based Formula Rates at our Regulated Operating Subsidiaries include a true-up mechanism that compares the actual revenue requirements of our Regulated Operating Subsidiaries to their billed revenues for each year to determine any over- or under-collection of revenue requirements and we record a revenue deferral or accrual for the difference. The true-up mechanisms under our Formula Rates are considered alternative revenue programs of rate-regulated utilities. Operating revenues arising from these alternative revenue programs are presented on our consolidated statements of comprehensive income in the line “Formula Rate true-up”, which is separate from the reporting of our tariff revenues, which are presented in the line “Transmission and other services.” Only the initial origination of our alternative revenue program revenue is reported in the Formula Rate true-up line on our consolidated statements of comprehensive income. When those amounts are subsequently included in the price of utility service and billed or refunded to customers, we account for that event as the recovery or settlement of the associated regulatory asset or regulatory liability, respectively. Refer to Note 6 under “Cost-Based Formula Rates with True-Up Mechanism” and Note 4 under “Formula Rate True-Up” for a discussion of our revenue accounting under our cost-based Formula Rates.

Transmission Services

Through our Regulated Operating Subsidiaries, we generate nearly all our revenue from providing electric transmission services over our transmission systems.

Due to the seasonal fluctuations of actual load, the unbilled revenue amount generally increases during the spring and summer and decreases during the fall and winter. See Note 5 for information on changes in unbilled accounts receivable.

Other Services

Other services revenue consists of rental revenues, easement revenues and amounts from providing ancillary services. A portion of other services revenue is treated as a revenue credit and reduces gross revenue requirement when calculating net revenue requirement under our Formula Rates. Total other services revenue was $6 million for each of the years ended December 31, 2023, 2022 and 2021.

Formula Rate True-Up

The true-up mechanism under our Formula Rates is considered an alternative revenue program of a rate-regulated utility given it permits our Regulated Operating Subsidiaries to adjust future rates in response to past activities or completed events in order to collect our actual revenue requirements under our Formula Rates. In accordance with our accounting policy, only the current year origination of the true-up is reported as a Formula Rate true-up.
