PART I

Item 1. BUSINESS

Tampa Electric Company, referred to as TEC, was incorporated in Florida in 1899 and was reincorporated in 1949. All of TEC’s common stock is owned by TECO Holdings. TECO Holdings is an indirect, wholly owned subsidiary of Emera. Therefore, TEC is an indirect, wholly owned subsidiary of Emera.

TEC is a public utility operating within the State of Florida. TEC is comprised of the electric division, referred to as Tampa Electric, and prior to January 1, 2023, also included the natural gas division, referred to as PGS. Tampa Electric provides retail electric service to approximately 855,000 customers in West Central Florida with a net winter system generating capacity of 6,620 MW at December 31, 2024.

On January 1, 2023, TEC transferred the assets and liabilities of its PGS division into a separate corporation called Peoples Gas System, Inc. This new corporation is a wholly owned subsidiary of a newly formed gas operations holding company, TECO Gas Operations, Inc., a wholly owned subsidiary of TECO Holdings. See Note 1 to the 2024 Annual TEC Consolidated Financial Statements for information regarding the separation of PGS from TEC.

TEC makes its SEC filings available free of charge on Tampa Electric’s website (www.tampaelectric.com/company/about/) as soon as reasonably practicable after they are filed with the SEC. TEC’s electronic SEC filings are also available on the SEC’s website (www.sec.gov).

TEC Revenues

TEC’s revenues consist of sales to residential, commercial, industrial and other customers. TEC’s residential load generally comprises individual homes, apartments and condominiums. Commercial customers include small retail operations, large office and commercial complexes, universities and hospitals. Industrial customers include manufacturing facilities, power generation customers and other large volume operations. Other sales volumes consist primarily of off-system sales to other utilities and revenues from street lighting.

For TEC’s revenue and other financial information by operating segments, see Note 11 to the 2024 Annual TEC Consolidated Financial Statements.

TEC Human Capital

Tampa Electric had 2,587 employees as of December 31, 2024, substantially all of whom are located in Florida. Of these employees, 717 were represented by the International Brotherhood of Electrical Workers and 141 were represented by the Office and Professional Employees International Union.

Maintaining a robust pipeline of talent is crucial to TEC’s ongoing success and is a key aspect of succession planning efforts across the organization. TEC is committed to investing in its employees through training and development programs as well as a tuition assistance program to promote continued professional growth. TEC provides a competitive compensation package that includes base pay, annual short-term incentives based on the achievement of corporate goals and performance, long-term incentives (applicable to eligible employee population), and health and retirement benefits.

TAMPA ELECTRIC – Electric Operations

Tampa Electric is engaged in the generation, purchase, transmission, distribution and sale of electric energy. The retail territory served comprises an area of about 2,000 square miles in West Central Florida, including Hillsborough County and parts of Polk, Pasco and Pinellas Counties. The principal communities served are Tampa, Temple Terrace, Winter Haven, Plant City and Dade City. Tampa Electric engages in wholesale sales to utilities and other resellers of electricity. At December 31, 2024, Tampa Electric had two generating stations in or near Tampa, one generating station in southwestern Polk County, 27 photovoltaic power stations (fifteen in Hillsborough County, ten in Polk County, and two in Pasco County), and one energy storage site.

No significant part of Tampa Electric’s business is dependent upon a single or limited number of customers where the loss of any one or several would have a significant adverse effect on Tampa Electric. Tampa Electric experiences summer peak loads due to the use of air conditioning and other cooling equipment and winter peak loads due to electric space heating and fewer daylight hours.

Regulation

Base Rates

Tampa Electric’s retail operations are regulated by the FPSC. The FPSC’s objective is to set rates at a level that provides an opportunity for the utility to collect revenues (revenue requirements) equal to its prudently incurred costs of providing service to customers, plus a reasonable return on invested capital.

The costs of owning, operating and maintaining the utility systems, excluding fuel, conservation costs, purchased power, storm protection plan projects and certain environmental costs, are recovered through base rates. These costs include O&M expenses, depreciation, taxes, and a return on investment in assets providing electric service (rate base). The rate of return on rate base, which is intended to approximate a company’s weighted cost of capital, primarily includes its costs for debt, deferred income taxes (at a zero cost rate) and an allowed ROE. Base rates are determined in FPSC rate setting hearings which occur at the initiative of Tampa Electric, the FPSC or other interested parties.

Tampa Electric’s 2024, 2023 and 2022 base rates reflect a settlement agreement approved by the FPSC on November 10, 2021. Tampa Electric's 2025 base rates reflect an FPSC order issued on February 3, 2025. See Note 3 to the 2024 Annual TEC Consolidated Financial Statements for information regarding Tampa Electric’s base rates, ROE and other regulatory matters.

6

Other Cost Recovery

Tampa Electric has five cost recovery clauses.

(1)Tampa Electric has a fuel recovery clause allowing recovery of actual fuel costs from customers through annual fuel rate adjustments. Differences between actual prudently incurred fuel costs and amounts recovered from customers in a year are recovered from or returned to customers in a subsequent period.

(2)Tampa Electric has a capacity recovery clause allowing recovery of firm demand payments associated with purchased power agreements.

(3)Tampa Electric has an environmental cost recovery clause which allows it to earn a return on investments in new facilities to comply with new environmental regulations and to recover the costs to operate and maintain these facilities.

(4)Through its conservation cost recovery clause, Tampa Electric offers its customers a comprehensive array of residential and commercial programs that have enabled it to meet its required demand side management goals, reduce weather-sensitive peak demand and conserve energy.

(5)Tampa Electric has a Storm Protection Plan cost recovery clause allowing recovery of prudent transmission and distribution storm hardening costs for incremental activities not already included in base rates as outlined in the programs in its approved Storm Protection Plan.

During the fourth quarter of 2024, the FPSC approved cost-recovery rates for the above clauses effective January 1, 2025. See Note 3 to the 2024 Annual TEC Consolidated Financial Statements for further information. In addition, Tampa Electric’s 2021 rate case settlement agreement established a mechanism to recover the costs of retiring coal generation units and meter assets over a period of 15 years. The recovery started in January 2022 and will survive the term of the settlement agreement.

FERC and Other Regulations

Tampa Electric is subject to regulation by the FERC in various respects, including wholesale power sales, certain wholesale power purchases, transmission and ancillary services and accounting practices.

Tampa Electric is subject to federal, state and local environmental laws and regulations pertaining to air and water quality, land use, power plant, substation and transmission line siting, noise and aesthetics, solid waste and other environmental matters (see the Environmental Compliance section of the MD&A).

Competition

Tampa Electric’s retail electric business is substantially free from direct competition with other electric utilities, municipalities and public agencies. The principal form of competition at the retail level consists of self-generation available to users of electric energy. Such users may seek to expand their alternatives through various initiatives, including legislative and/or regulatory changes that would permit competition at the retail level. Tampa Electric intends to retain and expand its retail business by managing costs and providing quality service to retail customers.

Generation Sources

In 2024 and 2023, 89% and 88%, respectively, of Tampa Electric’s gross generation of electricity was natural gas-fired, with solar representing 11% and 8%, respectively, and coal representing less than 1% and 4%, respectively. In 2024 and 2023, Tampa Electric used its generating units to meet 91% and 92%, respectively, of the total system load requirements, with the remaining 9% and 8%, respectively coming from purchased power. Tampa Electric is required to maintain a generation capacity greater than firm peak demand. Tampa Electric meets the planning criteria for reserve capacity established by the FPSC, which is a 20% reserve margin over firm peak demand.

The table below presents information regarding Tampa Electric’s generation costs.

Average cost per MMBTU	2024		2023		2022
Natural Gas (1)	$	3.65	$	2.81	$	8.32
Coal (2)		15.47		5.00		3.52
Average generation cost per MWh (3)		28.47		30.97		37.85

(1)Represents the cost of natural gas, transportation, storage, balancing, and fuel losses for delivery to the energy center.

(2)Represents the cost of coal and transportation.

7

(3)Represents the average generation cost per MWh including solar.

Tampa Electric’s fuel costs are affected by commodity prices and generation mix that is largely dependent on economic dispatch of the generating fleet, dispatching the lowest fuel cost options first (solar renewable energy being zero fuel costs), such that the incremental cost of generation increases as sales volumes increase. Generation mix may also be affected by plant outages, plant performance, availability of lower priced short-term purchased power, compliance with environmental standards and regulations, and availability of solar resources.

Natural Gas. Tampa Electric maintains gas commodity, pipeline transportation and storage contracts. As of December 31, 2024, 69% of Tampa Electric’s 2.0 million billion cubic feet of gas storage capacity was full. Tampa Electric has contracted for, on average, 48% of its expected gas needs for the January through December 2025 period. Tampa Electric expects to issue requests for proposals (RFPs) to meet its remaining 2025 gas needs and begin contracting for its 2026 requirements. Additional volume requirements are purchased in the short-term spot market.

Coal. Tampa Electric burned less than 0.1 million tons of coal during 2024, with similar usage anticipated in 2025. All of Tampa Electric's expected coal need in 2025 is under contract and stored on site. Tampa Electric takes coal deliveries primarily by water and uses transportation agreements with a rail provider if spot coal supplies are needed.

Franchises and Other Rights

Florida utilities must obtain franchises to operate in certain municipalities. Tampa Electric holds franchises and other rights that, together with its charter powers, govern the placement of Tampa Electric’s facilities on the public rights-of-way that it carries for its retail business in the localities it serves. The franchises specify the negotiated terms and conditions governing Tampa Electric’s use of public rights-of-way and other public property within the municipalities it serves during the term of the franchise agreement. Florida municipalities are prohibited from granting any franchise for a term exceeding 30 years.

Tampa Electric has franchise agreements with 13 incorporated municipalities within its retail service area. At December 31, 2024, these agreements have various expiration dates ranging through 2052 and are expected to be renewed under similar terms and conditions.

Franchise fees expense totaled $59 million and $67 million in 2024 and 2023, respectively. Franchise fees are calculated using a formula based primarily on electric revenues and are recovered on a dollar-for-dollar basis from customers.

Utility operations in Hillsborough, Pinellas and Polk Counties outside of incorporated municipalities are conducted in each case under one or more permits granted by the Florida Department of Transportation or the County Commissioners of such counties. There is no law limiting the time for which such permits may be granted. There are no fixed expiration dates for the Hillsborough County, Pinellas County and Polk County agreements.

Environmental Matters

Tampa Electric operates stationary sources with air emissions regulated by the Clean Air Act. Its operations are also impacted by provisions in the Clean Water Act and federal and state legislative initiatives on environmental matters. TEC, through its Tampa Electric division and former PGS division, is a PRP for certain superfund sites and, through its former PGS division, for certain former manufactured gas plant sites. See Environmental Compliance section of the MD&A for additional information. As a result of the separation of the PGS division, PGS is now the responsible party for those sites (in addition to third party PRPs for certain sites). See Note 1 to the 2024 Annual TEC Consolidated Financial Statements for information regarding the separation of PGS from TEC.

PEOPLES GAS SYSTEM – Gas Operations

On January 1, 2023, TEC transferred the assets and liabilities of its PGS division into a separate corporation called Peoples Gas System, Inc. This new corporation is a wholly owned subsidiary of a newly formed gas operations holding company, TECO Gas Operations, Inc., a wholly owned subsidiary of TECO Energy. From and after January 1, 2023, the PGS business is no longer operated by TEC. See Note 1 to the 2024 Annual TEC Consolidated Financial Statements for further information regarding the separation of PGS from TEC. For information regarding PGS's Business in 2022, see “Item 1. Business” of TEC’s Annual Report on Form 10-K for the year ended December 31, 2022.

Item 1A. RISK FACTORS

Risks Relating to TEC’s Business and Strategy

Regulatory, Legislative, and Legal Risks

Tampa Electric is regulated; changes in regulation or the regulatory environment could reduce revenues, increase costs or competition.

Tampa Electric operates in a regulated industry. Retail operations, including the rates charged and costs eligible for recovery under clauses, are regulated by the FPSC, and Tampa Electric’s wholesale power sales and transmission services are subject to regulation by the FERC. Changes in regulatory requirements or regulatory actions could have an adverse effect on TEC’s financial performance by, for example, reducing revenues, increasing competition or costs, threatening investment recovery or impacting rate structure. Additionally, if regulators deny or delay cost recovery approvals, Tampa Electric’s earnings could be negatively impacted.

If Tampa Electric earns returns on equity above its allowed range, indicating a trend, those earnings could be subject to review by the FPSC. Ultimately, prolonged returns above its allowed range could result in credits or refunds to customers, which could reduce future earnings and cash flow.

Changes in the environmental and land use laws and regulations affecting its business could increase TEC’s costs or curtail its activities.

TEC’s business is subject to regulation by various governmental authorities dealing with air, water and other environmental matters. Changes in compliance requirements or the interpretation by governmental authorities of existing requirements may impose additional costs on TEC, requiring cost-recovery proceedings and/or requiring it to modify its business model.

The computation of TEC’s provision for income taxes is impacted by changes in tax legislation.

Any changes in tax legislation could affect TEC’s future cash flows and financial position. The value of TEC’s existing deferred tax assets and liabilities are determined by existing tax laws and could be impacted by tax law changes, including any changes to the Inflation Reduction Act, as well as additional interpretations or technical corrections impacting the amount and timing of income tax payments or reduce or limit the ability to claim certain deductions and use carryforward tax benefits and/or credits. See Note 4 of the 2024 Annual TEC Consolidated Financial Statements for further information regarding TEC’s income taxes.

Tampa Electric may not be able to secure adequate rights-of-way to construct transmission lines and distribution-related facilities and could be required to find alternate ways to provide adequate sources of energy and maintain reliable service for their customers.

Tampa Electric relies on federal, state and local governmental agencies to secure rights-of-way and siting permits to construct transmission lines and distribution-related facilities. If adequate rights-of-way and siting permits to build new transportation and transmission lines cannot be secured, then Tampa Electric:

• May need to remove or abandon its facilities on the property covered by rights-of-way or franchises and seek alternative locations for its transmission or distribution facilities;

• May need to rely on more costly alternatives to provide energy to its customers;

• May not be able to maintain reliability in its service area;

• May need to exercise the power of eminent domain, which can be costly and take time; and/or

• May experience a negative impact on its ability to provide electric service to new customers.

The franchise rights held by Tampa Electric could be lost in the event of a breach by such utilities or could expire and not be renewed.

Tampa Electric holds franchise agreements with counterparties throughout its service area. In some cases, these rights could be lost in the event of a breach of these agreements. These agreements are for set periods and could expire and not be renewed upon

9

expiration of the then-current terms. From time to time municipalities seek to include provisions allowing them to purchase the portion of the utility’s system located within a given municipality’s boundaries under certain conditions.

Operational and Construction Risks

TEC’s business is sensitive to variations in weather and the effects of extreme weather and has seasonal variations.

TEC’s utility business is affected by variations in general weather conditions including severe weather. Energy sales by its electric utility are particularly sensitive to seasonal variations in weather conditions, including unusually mild summer or winter weather that cause lower energy usage for cooling or heating purposes. Tampa Electric has both summer and winter peak periods that are dependent on weather conditions. Tampa Electric forecasts energy sales based on normal weather, which represents a long-term historical average. If there is unusually mild weather, or if climate change or other factors cause significant variations from normal weather, this could have a material impact on energy sales.

TEC is subject to several risks that arise or may arise from climate change.

TEC is subject to risks that may arise from the impacts of climate change. There is increasing public concern about climate change and growing support for reducing carbon dioxide emissions. Municipal, state, and federal governments have been setting policies and enacting laws and regulations to deal with climate change impacts in a variety of ways, including de-carbonization initiatives and promotion of cleaner energy and renewable energy generation of electricity. Refer to “changes in the environmental and land use laws and regulations” above. Insurance companies have begun to limit their exposure to coal-fired electricity generation and are evaluating the medium and long-term impacts of climate change which may result in fewer insurers, more restrictive coverage and increased premiums.

Climate change may lead to increased frequency and intensity of weather events and related impacts such as storms, hurricanes, cyclones, heavy rainfall, extreme winds, wildfires, flooding and storm surge. The potential impacts of climate change, such as rising sea levels and larger storm surges from more intense hurricanes, can combine to produce even greater damage to coastal generation and other facilities. Climate change is also characterized by rising global temperatures. Increased air temperatures may bring increased frequency and severity of wildfires, including within TEC’s service territory. Refer to “variations in weather” above.

High winds and lack of precipitation increase the risk of wildfires resulting from TEC’s infrastructure. The risk of wildfires is addressed primarily through asset management, storm hardening, and vegetation management programs for the electric utility. If it is found to be responsible for such a fire, TEC could suffer material costs, losses and damages, which could materially affect TEC’s business, access to capital, financial condition and results of operations including its reputation with customers, regulators, governments and financial markets. Resulting costs could include fire suppression costs, regeneration, timber value, increased insurance costs and costs arising from damages and losses incurred by third parties.

TEC is subject to physical risks that arise, or may arise, from global climate change, including damage to operating assets from more frequent and intense weather events and from wildfires due to warming air temperatures and increasing drought conditions. Some of Tampa Electric’s fossil fueled generation assets are located at or near coastal sites and as such are exposed to the separate and combined effects of rising sea levels and increasing storm intensity, including storm surges and flooding. Refer to “variations in weather” above.

Failure to address issues related to climate change could affect TEC’s reputation with stakeholders, its ability to operate and grow, and TEC’s access to, and cost of, capital. Refer to “Financial, Economic, and Market Risks” below.

Changing carbon-related costs, policy and regulatory changes and shifts in supply and demand factors could lead to more expensive or more scarce products and services that are required by TEC in its operations. This could lead to supply shortages, delivery delays and the need to source alternate products and services.

Depending on the regulatory response to government legislation and regulations, TEC may be exposed to the risk of reduced recovery through rates in respect of the affected assets. Valuation impairments could result from such regulatory outcomes.

TEC could face litigation or regulatory action related to environmental harms from carbon dioxide emissions or climate change public disclosure issues.

For thermal plants requiring cooling water, reduced availability of water resulting from climate change could adversely impact operations or the costs of operations.

10

The facilities and operations of TEC could be affected by natural disasters or other catastrophic events.

TEC’s facilities and operations are exposed to potential damage and partial or complete loss resulting from environmental disasters (e.g., hurricanes, floods, high winds, fires and earthquakes), equipment failures, terrorist or physical attacks, vandalism, a major accident or incident at one of the sites, and other events beyond the control of TEC. The operation of generation, transmission and distribution systems involves certain risks, including fires, explosions, pipeline ruptures, damage to solar panels and other generation assets, and other hazards and risks that may cause unforeseen interruptions, personal injury, death, or property damage. There have also been physical attacks on critical infrastructure around the world. In the event of a physical attack that disrupts service to customers, revenues would be reduced, and costs would be incurred to repair and restore systems. These types of events, either impacting TEC’s facilities or the industry in general, could cause TEC to incur additional security and insurance-related costs, and could have adverse effects on its business and financial results. Any costs relating to such events may not be recoverable through insurance or rates.

TEC is exposed to potential risks related to cyberattacks and unauthorized access, which could cause system failures, disrupt operations or adversely affect safety.

TEC increasingly relies on information technology systems and network infrastructure to manage its business and safely operate its assets, including controls for interconnected systems of generation, distribution and transmission and financial, billing and other business systems. TEC also relies on third party service providers to conduct business. As TEC operates critical infrastructure, it may be at greater risk of cyberattacks by third parties, which could include nation-state controlled parties.

Cyberattacks can reach TEC’s networks with access to critical assets and information via their interfaces with less critical internal networks or via the public internet. Cyberattacks can also occur via personnel with direct access to critical assets or trusted networks. An outbreak of infectious disease, a pandemic or a similar public health threat may cause disruption in normal working patterns including wide scale “work from home” policies, which could increase cybersecurity risk as the quantity of both cyberattacks and network interfaces increases. Refer to the risk factor below regarding public health risk. Methods used to attack critical assets could include general purpose or energy-sector-specific malware delivered via network transfer, removable media, viruses, attachments or links in e-mails. The methods used by attackers are continuously evolving and can be difficult to predict and detect.

TEC’s systems, assets and information could experience security breaches that could cause system failures, disrupt operations or adversely affect safety. Such breaches could compromise customer, employee-related or other information systems and could result in loss of service to customers or the unavailability, release, destruction or misuse of critical, sensitive or confidential information. These breaches could also delay delivery or result in contamination or degradation of hydrocarbon products TEC transports, stores or distributes.

Should such cyberattacks or unauthorized accesses materialize, TEC could suffer costs, losses and damages, all or some of which may not be recoverable through insurance, legal, regulatory cost recovery or other processes. If not recovered through these means, they could materially adversely affect TEC’s business and financial results including its reputation and standing with customers, regulators, governments and financial markets. Resulting costs could include, amongst others, response, recovery and remediation costs, increased protection or insurance costs and costs arising from damages and losses incurred by third parties. If any such security breaches occur, there is no assurance that they can be adequately addressed in a timely manner.

With respect to certain of its assets, TEC is required to comply with rules and standards relating to cybersecurity and information technology including, but not limited to, those mandated by bodies such as the North American Electric Reliability Corporation. TEC cannot be assured that its operations will not be negatively impacted by a cyberattack.

Effects of an outbreak of infectious disease, another pandemic or a similar public health threat could have a negative impact on TEC’s operations.

An outbreak of infectious disease, a pandemic or a similar public health threat or a fear of any of the foregoing, could adversely impact TEC, including by causing operating, supply chain and project development delays and disruptions, labor shortages and shutdowns (including as a result of government regulation and prevention measures), and delays in regulatory decisions and proceedings, which could have a negative impact on TEC’s operations.

Any adverse changes in general economic and market conditions arising as a result of a public health threat could negatively impact demand for electricity, revenue, operating costs, timing and extent of capital expenditures, results of financing efforts, or credit risk, counterparty risk and collection risk, which could result in a material adverse effect on TEC’s business.

11

Financial, Economic, and Market Risks

National and local economic conditions can have a significant impact on the results of operations, net income and cash flows at TEC.

The business of TEC is concentrated in Florida. If economic conditions decline, retail customer growth rates may stagnate or decline, and customers’ energy usage may decline, adversely affecting TEC’s results of operations, net income and cash flows. A factor in customer growth in Florida is net in-migration of new residents, both domestic and non-U.S. A slowdown in the U.S. economy could reduce the number of new residents and slow customer growth.

Potential competitive changes may adversely affect TEC.

There is competition in wholesale power sales across the United States. Some states have mandated or encouraged competition at the retail level and, in some situations, required divestiture of generating assets. While there is active wholesale competition in Florida, the retail electric business has remained substantially free from direct competition. Changes in the competitive environment occasioned by legislation, regulation, market conditions or initiatives of other electric power providers or voters, particularly with respect to retail competition, could adversely affect Tampa Electric’s business and its expected performance.

Florida electric utilities, including Tampa Electric, currently benefit from operating in a regulated environment with limited competition in their market for retail customers. However, the commercial and regulatory frameworks under which Tampa Electric operates can be impacted by changes in government and shifts in government policy. These include initiatives regarding deregulation or restructuring of the energy industry, which may result in increased competition and unrecovered costs that could adversely affect operations, net income and cash flows.

Disruption of fuel supply could have an adverse impact on the financial condition of TEC.

Tampa Electric depends on third parties to supply fuel, including natural gas and coal. As a result, there are risks of supply interruptions and fuel-price volatility. Disruption of fuel supplies or transportation services for fuel, whether because of weather-related problems, strikes, lock-outs, break-downs of transportation facilities, pipeline failures or other events, could impair the ability to deliver or generate electricity and could adversely affect operations. The loss of fuel suppliers or the inability to renew existing coal and natural gas contracts at favorable terms could significantly affect the ability to serve customers and have an adverse impact on the financial condition and results of operations of TEC.

Commodity price changes may affect the operating costs and competitive positions of TEC’s business.

TEC’s business is sensitive to changes in gas, coal and other commodity prices. Any changes in the availability of these commodities could affect the prices charged by suppliers as well as suppliers’ operating costs and the competitive positions of their products and services.

In the case of Tampa Electric, fuel costs used for generation are affected primarily by the cost of natural gas and coal. Tampa Electric is able to recover prudently incurred costs of fuel through retail customers’ bills, but increases in fuel costs affect electric prices and, therefore, the competitive position of electricity against other energy sources.

The ability to make sales of, and the margins earned on, wholesale power sales are affected by the cost of fuel to Tampa Electric, particularly as it compares to the costs of other power producers.

TEC may face risks associated with international and national trade laws and regulations which could affect operating costs.

Trade restrictions and imposition of new tariffs or trade restrictions could impact the availability and/or price of materials and equipment needed to support operations and capital investment and may affect operating costs and financial results.

Developments in technology could reduce demand for electricity.

Research and development activities are ongoing for new technologies that produce power or reduce power consumption. These technologies include renewable energy, customer-oriented generation, energy storage, energy efficiency and more energy-efficient appliances and equipment. Advances in these or other technologies could reduce the cost of producing electricity, or otherwise make Tampa Electric’s existing generating facilities uneconomic. Advances in such technologies could reduce demand for electricity, which could negatively impact the results of operations, net income and cash flows of TEC.

12

Results at TEC may be affected by changes in customer energy-usage patterns.

For the past several years, at Tampa Electric and electric utilities across the United States, weather-normalized electricity consumption per residential customer has declined due to the combined effects of voluntary conservation efforts and improvements in equipment efficiency.

Forecasts by TEC are based on normal weather patterns and trends in customer energy-usage patterns. TEC could be negatively impacted if customers further reduce their energy usage in response to increased energy efficiency, economic conditions or other factors.

Increased customer use of distributed generation could adversely affect Tampa Electric.

In many areas of the United States, including in the markets where TEC operates, there is growing use of rooftop solar panels, small wind turbines and other small-scale methods of power generation, known as distributed generation. Distributed generation is encouraged and supported by various constituent groups, tax incentives, renewable portfolio standards and special rates designed to support such generation.

Increased usage of distributed generation can reduce utility electricity sales but does not reduce the need for ongoing investment in infrastructure to maintain or expand the transmission and distribution grid to reliably serve customers. Continued utility investment that is not supported by increased energy sales causes rates to increase for customers, which could further reduce energy sales and reduce future earnings and cash flows.

Failure to attract and retain an appropriately qualified workforce, or workforce disruptions, could adversely affect TEC’s financial results.

Events such as increased retirements due to an aging workforce or the departure of employees for other reasons without appropriate replacements, mismatch of skill sets to future needs, or unavailability of contract resources may lead to operating challenges such as lack of resources, loss of knowledge, and a lengthy time period associated with skill development. Failure to attract and hire employees, including the ability to transfer significant internal historical knowledge and expertise to the new employees, or workforce disruptions due to work stoppages or strikes, or the future availability and cost of contract labor may cause costs to operate TEC’s systems to rise. If TEC is unable to successfully attract and retain an appropriately qualified workforce, results of operations could be negatively impacted.

Liquidity and Capital Requirements Risks

TEC’s indebtedness could adversely affect its business, financial condition and results of operations, as well as its ability to meet its payment obligations on its debt.

TEC has indebtedness that it is obligated to pay. It must meet certain financial covenants as defined in the applicable agreements to borrow under its credit facilities. Also, TEC has certain restrictive covenants in specific agreements and debt instruments. The level of TEC’s indebtedness and potential inability to meet the requirements of the restrictive covenants contained in its debt obligations could have significant consequences to its business, could create risk for the holders of its debt, and could limit its ability to obtain additional financing (see Management’s Discussion & Analysis – Significant Financial Covenants section). Such risks include:

•making it more difficult for TEC to satisfy its debt obligations and other ongoing business obligations, which may result in defaults;

•events of default if it fails to comply with the financial and other covenants contained in the agreements governing such debt, which could result in all of its debt becoming immediately due and payable or require it to negotiate an amendment to financial or other covenants that could cause it to incur additional fees and expenses;

•reducing the availability of cash flow to finance its business and limiting its ability to obtain additional financing for these purposes;

•increasing its vulnerability to the impact of adverse economic and industry conditions;

•limiting its flexibility in planning for, or reacting to, and increasing its vulnerability to, changes in its business and the overall economy;

•and increasing its cost of borrowing.

13

TEC has obligations that do not appear on its balance sheet, such as letters of credit. To the extent material, these obligations are disclosed in the notes to the financial statements.

Financial market conditions could limit TEC’s access to capital and increase TEC’s costs of borrowing or refinancing, or have other adverse effects on its results.

TEC has debt maturing in subsequent years, which TEC anticipates will need to be refinanced. Future financial market conditions could limit TEC’s ability to raise the capital it needs and could increase its interest costs, which could reduce earnings and cash flows.

Declines in the financial markets or in interest rates or rates of return used to determine benefit assets or obligations could increase TEC’s pension expense or the required cash contributions to maintain required levels of funding for its plan.

TEC is a participant in the comprehensive retirement plans of TECO Energy. Under calculation requirements of the Pension Protection Act, as of the January 1, 2024 measurement date, TECO Energy’s pension plan was fully funded. Any future declines in the financial markets or interest rates could increase the amount of contributions required to fund its pension plan in the future and could cause pension expense to increase.

TEC’s financial condition and results could be adversely affected if its capital expenditures are greater than forecast or costs are not recoverable through rates.

TEC’s capital plan includes significant investments in generation, infrastructure modernization and customer-focused technologies. Any projects planned or currently in construction, particularly significant capital projects, may be subject to risks including, but not limited to, impact on costs from schedule delays, risk of cost overruns, ensuring compliance with operating and environmental requirements and other events within or beyond TEC’s control. Total costs may be higher than estimated, and there can be no assurance that TEC will be able to obtain the necessary project approvals, regulatory outcomes or applicable permits at the federal, state and/or local level to recover such expenditures through regulated rates. If TEC’s capital expenditures exceed the forecasted levels or are not recoverable, it may need to draw on credit facilities or access the capital markets on unfavorable terms.

TEC’s financial condition and ability to access capital may be materially adversely affected by multiple ratings downgrades to below investment grade.

The senior unsecured debt of TEC is rated by S&P at ‘BBB+’, by Moody’s at ‘A3’ and by Fitch at ‘A’. A downgrade to below investment grade by the rating agencies, which would require a four-notch downgrade by Moody’s and Fitch and a three-notch downgrade by S&P, may affect TEC’s ability to borrow, may change requirements for future collateral or margin postings, and may increase financing costs, which may decrease earnings. Downgrades could adversely affect TEC’s relationships with customers and counterparties. Some of the factors that can affect TEC’s credit ratings are cash flows, liquidity, the amount of debt as a component of total capitalization, political, legislative, and regulatory actions, and changes in Emera’s credit ratings.

In the event TEC’s ratings were downgraded to below investment grade, certain agreements could require immediate payment or full collateralization of net liability positions. Counterparties to its derivative instruments could request immediate payment or full collateralization of net liability positions. Credit provisions in long-term gas transportation agreements would give the transportation providers the right to demand collateral, which is estimated to be approximately $84 million at December 31, 2024.

TEC may be subject to risks relating to its separation from PGS.

On January 1, 2023, TEC completed the separation from its former PGS division to PGSI. TEC’s business is less diversified as a result of the separation since its remaining Tampa Electric business serves only electric utility customers and operates in a more narrow geographic area than its former PGS division.

The separation is intended to be a tax-free transaction for U.S. federal income tax purposes. The IRS has issued a private letter ruling (IRS Ruling) to the effect that, subject to the limitations specified therein and the accuracy and compliance with certain representations, warranties and covenants, the distribution of the PGSI stock, together with certain related transactions, will qualify as a tax-free “reorganization” for U.S. federal income tax purposes. If any of these items are inaccurate, the separation may not qualify for tax-free treatment, which could result in material tax liabilities for TEC.

Item 1C. CYBERSECURITY

TEC assesses, identifies, and manages material risks from cybersecurity threats under the governance of its Cyber Security Framework and Information Security Policy, as well as several related policies and procedures addressing areas such as threat vulnerability management, cyber risk management, data protection and classification, network security, access control, incident

14

response, security awareness, employee training and asset management. These policies and related standards require identification of all Information Technology (IT) and Operational Technology (OT) critical facilities and/or cyber assets, and sufficient controls for IT and OT asset inventory, including responsibilities for assets, information owners, and asset disposition processes. From a security perspective, TEC’s Information Security group is directed at protecting all aspects of data and how information is stored, transmitted, processed, and used in business processes. TEC’s Corporate Security group is responsible for protecting physical assets including critical facilities, protection of employees, and related physical security risks.

TEC’s Information Security group of the Information Technology department has the direct responsibility for developing, monitoring, and enforcing information security standards and procedures; reviewing and approving all network interconnections for compliance to security standards; and assisting, consulting, and training individuals throughout TEC in the use of appropriate information security practices. This group is responsible for ensuring that all IT and OT cyber systems, assets, and networks are aligned with Emera and affiliate cybersecurity framework. TEC engages independent third-party consultants from time to time to assess the adequacy of its cybersecurity measures and assist in implementing any appropriate actions to address any vulnerabilities identified. In addition, TEC participates in an Electric Power Research Institute (EPRI) research project to develop cybersecurity performance metrics. EPRI offers a web-based platform, which supports automated cybersecurity data collection, security metrics calculation, visualization, and analysis. The Vice President of Information Technology and Chief Information Officer (CIO), who reports to the President and Chief Executive Officer, oversees this group and is responsible for managing the program, in collaboration with TEC’s businesses and functions. TEC’s CIO has advanced degrees in computer science and extensive experience in cybersecurity and information technology, including many years of experience at large organizations leading cybersecurity, IT processes and controls, strategy, architecture, delivery and support of IT applications, and overseeing large groups of employees and contractors responsible for carrying out these responsibilities.

TEC’s Vendor Risk Management process includes conducting risk assessments to identify and monitor cybersecurity risks associated with third-party service providers, including threat detection and security event notifications. TEC also has requirements for third-party service providers which include regulatory compliance and meeting policies and standards based on the National Institute of Standards and Technology Cybersecurity Frameworks. TEC’s processes also provide for mitigating cybersecurity risk from third parties through seeking to include in its agreements with third-party service providers, as applicable, cybersecurity provisions designed to appropriately address such risks.

TEC’s IT Business Continuity – Emergency Contingency Response Plan is updated periodically and reviewed at least annually. This plan includes guidelines for the escalation and communication of cybersecurity incidents, including a requirement to timely report to TEC’s executive leadership and Board of Directors based on an assessment of the risk and other specified criteria. TEC has established a cyber incident response team to prepare for, mitigate, and remediate cybersecurity incidents, which is integrated within Emera’s enterprise crisis management framework.

Cybersecurity risks are integrated into TEC’s overall risk management process through the collaboration of the cybersecurity professionals and TEC’s and Emera’s risk management functions to assess threat levels on an affiliate and corporate basis and identify steps and resources appropriate to manage such risks. The Board of Directors oversees the management of risks from cybersecurity threats through receiving regular reports from the CIO, which include updates on TEC’s performance with preparing, preventing, detecting, responding to, mitigating, and recovering from cybersecurity incidents. Should a cybersecurity threat or incident pose a significant risk to TEC, TEC's processes provide that the CIO, through the CEO, as appropriate, would promptly inform the Board regarding any such threat or incident. The CIO also provides regular updates on the key elements of its cybersecurity program to the Emera Board’s Risk and Sustainability Committee, which has oversight over Emera’s enterprise risk management framework, including oversight over cybersecurity risk.

While to date TEC has not detected a significant compromise of its cybersecurity systems, significant data loss or any material financial losses related to cybersecurity attacks, it is possible that TEC could experience a significant event in the future. Risks and exposures related to cybersecurity attacks are expected to remain high for the foreseeable future due to the rapidly evolving nature and sophistication of these threats. See Item 1A. Risk Factors, “TEC is exposed to potential risks related to cyberattacks and unauthorized access, which could cause system failures, disrupt operations or adversely affect safety” for a further discussion of risks related to cybersecurity.

Item 2. PROPERTIES

TEC believes that its physical properties are adequate to carry on its business as currently conducted. The properties of Tampa Electric are subject to a first mortgage bond indenture under which no bonds are currently outstanding.

Tampa Electric has electric generating stations in service, with a December 2024 net winter generating capability of 6,620 MWs. Tampa Electric assets include the Big Bend Power Station (1,623 MWs capacity), the Bayside Power Station (2,212 MWs capacity) and the Polk Power Station (1,420 MWs capacity). Also included in Tampa Electric’s assets as of December 31, 2024 are twenty-seven solar arrays (1,350 MWs capacity) and one energy storage site (15 MWs capacity).

The transmission system consists of 1,362 total circuit miles of high voltage transmission lines, including underground and double-circuit lines. The distribution system consists of 6,053 circuit miles of overhead lines and 6,805 circuit miles of underground lines. As of December 31, 2024, there were 869,996 meters in service. All of this property is located in Florida.

Tampa Electric’s property, plant and equipment are owned, except that titles to some of the properties are subject to easements, leases, contracts, covenants and similar encumbrances common to properties of the size and character of those of Tampa Electric.

Tampa Electric has easements or other property rights for rights-of-way adequate for the maintenance and operation of its electrical transmission and distribution lines that are not constructed upon public highways, roads and streets. Transmission and distribution lines located in public ways are maintained under franchises or permits.

Tampa Electric has a lease for the office building in downtown Tampa, which serves as headquarters for TECO Holdings, Tampa Electric and PGS.

Item 3. LEGAL PROCEEDINGS

From time to time, TEC is involved in various legal, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies in the ordinary course of business. Where appropriate, accruals are made in accordance with accounting standards for contingencies to provide for matters that are probable of resulting in an estimable loss. For a discussion of legal proceedings and environmental matters, see Note 8 of the 2024 Annual TEC Consolidated Financial Statements.

PART II

Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

All of TEC’s common stock is owned by TECO Holdings, which in turn is owned by a subsidiary of Emera and, thus, is not listed on a stock exchange. Therefore, there is no market for such stock.

Item 7. MANAGEMENT’S DISCUSSION & ANALYSIS OF FINANCIAL CONDITIONS & RESULTS OF OPERATIONS

OVERVIEW

At December 31, 2024, Tampa Electric served approximately 855,000 customers in a 2,000-square-mile service area in West Central Florida and had electric generating plants with a winter peak generating capacity of 6,620 MW.

Prior to January 1, 2023, TEC had regulated electric and gas utility operations in Florida. From and after January 1, 2023, the gas utility operations are operated by PGSI, which is no longer a subsidiary of TEC. See Note 1 to the 2024 Annual TEC Consolidated Financial Statements for information regarding the separation of PGS from TEC. For information regarding PGS in 2022, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of TEC’s Annual Report on Form 10-K for the year ended December 31, 2022.

TEC is a wholly owned subsidiary of TECO Holdings, and TECO Holdings is a wholly owned subsidiary of Emera. Therefore, TEC is an indirect, wholly owned subsidiary of Emera. See Note 10 to the 2024 Annual TEC Consolidated Financial Statements for information regarding related party transactions.

OUTLOOK

TEC’s earnings are most directly impacted by the allowed rate of return on equity and the capital structures approved by the FPSC, the prudent management of operating costs, the approved recovery of regulatory deferrals, weather and its impact on energy sales, and the timing and amount of capital expenditures.

16

Tampa Electric anticipates earning within its ROE range in 2025. New base rates effective January 1, 2025, are projected to result in Tampa Electric's 2025 earnings to be higher than in 2024. Normalizing 2024 for weather, Tampa Electric sales volumes in 2025 are projected to be higher than in 2024 due to customer growth. Tampa Electric expects customer growth rates in 2025 to be comparable to 2024, reflective of the expected economic growth in Florida.

On April 2, 2024, Tampa Electric requested a base rate increase, reflecting an increased revenue requirement of $297 million, effective January 1, 2025, and additional adjustments of $100 million and $72 million for 2026 and 2027, respectively. Tampa Electric’s proposed rates include recovery of solar generation projects, energy storage capacity, a more resilient and modernized energy control center, and other resiliency and reliability projects. Prior to the rate case hearing, Tampa Electric submitted revisions to its requested base rate increase to reflect items that included production tax credits, energy storage life expectancy, and the company’s grid reliability and resilience project. The company’s August 22, 2024 requested revenue requirement reflects a base rate increase of $288 million, effective January 1, 2025, and adjustments of $92 million and $65 million for 2026 and 2027, respectively. From August 26 through 30, 2024, Tampa Electric’s rate case hearing was heard by the FPSC. On December 3, 2024, the FPSC rendered a decision during a Special Agenda and the final order, reflecting such decision, was issued on February 3, 2025. The FPSC decision includes an increase of $185 million in 2025 and adjustments of $87 million and $9 million in 2026 and 2027, respectively. The decision also allowed for equity in the capital structure to continue to be 54% from investor sources of capital. The allowed regulatory ROE range is 9.50% to 11.50% with a 10.50% midpoint, effective January 1, 2025. On February 18, 2025, a motion for reconsideration on certain aspects of the rate case order was filed with the FPSC. Tampa Electric will respond to this motion in February 2025. Tampa Electric expects the FPSC to reach a final decision on the motion in the second quarter of 2025.

On April 2, 2024, Tampa Electric requested a mid-course adjustment to its fuel and capacity charges, reflecting a $138 million reduction over 12 months, from June 2024 through May 2025. The requested reduction is due to a significant decrease in actual and projected 2024 natural gas prices since Tampa Electric submitted its projected 2024 costs in the fall of 2023. On May 7, 2024, the FPSC approved the mid-course adjustment.

Tampa Electric was impacted by Hurricane Idalia in September 2023. The related storm restoration costs were approximately $35 million, which were charged to the storm reserve regulatory asset. Hurricane Helene made landfall on September 26, 2024. Tampa Electric was impacted by Hurricane Helene, resulting in a peak number of customers out of approximately 100,000. As of December 31, 2024, TEC deferred $49 million to the storm reserve for future recovery, with a minimal impact to earnings. ​Hurricane Milton, the worst weather event to impact the area in over 100 years, made landfall on October 9, 2024. Tampa Electric was impacted by Hurricane Milton, resulting in a peak number of customers out of approximately 600,000. As of December 31, 2024, TEC deferred $340 million to the storm reserve for future recovery, with a minimal impact to earnings.

Restoration costs for the storms described above are deferred and will be collected from customers in subsequent periods. On February 4, 2025, the FPSC approved Tampa Electric’s petition filed on December 27, 2024 for the recovery of $466 million for costs associated with Hurricane Idalia, Hurricane Debby, Hurricane Helene and Hurricane Milton and the associated interest to replenish the storm reserve over an 18-month recovery period beginning in March 2025. The amount of cost-recovery is subject to a true-up mechanism with the FPSC.

In 2025, Tampa Electric expects to invest approximately $1.6 billion, excluding AFUDC, in capital projects. Capital projects include investments in solar, storm hardening, grid modernization, building resilience and energy storage. See Capital Investments below for further information.

These forecasts are based on our current assumptions described in the operating company discussion, which are subject to risks and uncertainties (see the Risk Factors section).

TAMPA ELECTRIC

Electric Operations Results

Tampa Electric’s net income in 2024 was $468 million, compared with $466 million in 2023. Results primarily reflected higher base revenues resulting from the 2021 rate case settlement agreement and customer growth, combined with additional storm protection plan return on investment, partially offset by higher depreciation and operations & maintenance expenses. Base revenues are energy sales excluding revenues from clauses, gross receipts taxes and franchise fees. Clauses, gross receipts taxes and franchise fees do not have a material effect on net income as these revenues substantially represent a dollar-for-dollar recovery of clause and other pass-through costs. See the Operating Revenues and Operating Expenses sections below for additional information.

18

The table below provides a summary of Tampa Electric’s revenue and expenses and energy sales by customer type.

Operating Revenues

Revenues were $111 million lower in 2024 than in 2023 primarily driven by decreased fuel clause and storm surcharge revenue, less favorable weather and the unfavorable impact of Hurricane Milton (see Note 3 to the TEC Consolidated Financial Statements), partially offset by customer growth and new base rates as a result of the 2021 rate case settlement agreement. Total degree days (a measure of heating and cooling demand) in Tampa Electric's service area in 2024 were 5% above normal (a 20-year statistical degree day average) and 2% below 2023, reflecting less favorable weather in 2024 compared to 2023. Total net energy for load, which is a calendar measurement of energy output, in 2024 was consistent with 2023.

Customer and Energy Sales Growth Outlook

Population growth in the area is forecasted to continue to be a major driver of customer growth. In 2025, energy sales volumes are expected to be similar to 2024 levels. In 2024, energy sales benefited from weather that was warmer than normal. Normalizing 2024 for weather, 2025 energy sales volumes are expected to be above 2024 levels due to customer growth. Tampa Electric expects 2025 customer growth to be approximately 1.6% and to continue at that level annually over the next few years.

Operating Expenses

In 2024, O&M expense was $50 million lower than in 2023 due to decreased storm cost recognition of $78 million related to storm surcharge revenue (offset in revenue), partially offset by increased operations and maintenance expenses of $12 million and regulatory deferrals of $16 million. The increase in operating expenses was primarily associated with increased solar operations, labor and software maintenance expenses. Depreciation and amortization expense increased $32 million in 2024 compared to 2023 as a result of additions to facilities and the in-service of generation projects.

O&M expense in 2025 is expected to increase compared to 2024 due to inflation. In 2025, depreciation expense is expected to increase compared to 2024 due to capital projects and plant additions.

Fuel Expense, Purchased Power and Fuel Cost Recovery

Total fuel expense decreased in 2024 from 2023 primarily due to lower natural gas prices. Total 2025 fuel and purchased power costs are expected to be higher than in 2024 due to higher gas demand driving the prices of natural gas.

On January 23, 2023, Tampa Electric requested an adjustment to its fuel charges to recover the $518 million final 2022 fuel under-recovery over a period of 21 months. The request also included an adjustment to 2023 projected fuel costs to reflect the reduction in natural gas prices since September 2022 for a projected reduction of $170 million for the balance of 2023. The changes were approved by the FPSC on March 7, 2023, effective April 1, 2023.

On April 2, 2024, Tampa Electric requested a mid-course adjustment to its fuel and capacity charges, reflecting a $138 million reduction over 12 months, from June 2024 through May 2025. The requested reduction is due to a significant decrease in actual and projected 2024 natural gas prices since Tampa Electric submitted its projected 2024 costs in the fall of 2023. On May 7, 2024, the FPSC approved the mid-course adjustment.

In December 2024, the FPSC approved cost-recovery rates for fuel and purchased power, capacity, environmental, conservation and storm protection plan costs for 2025. The rates include the expected cost for natural gas and coal in 2025. These rates are typically set annually, based on information provided in September of the year prior to the year the rates take effect.

OTHER ITEMS IMPACTING NET INCOME

Other Income

For the years 2024 and 2023, TEC’s other income was $48 million and $89 million, respectively, which included AFUDC-equity of $30 million and $19 million, respectively, interest income from affiliate of $0 million and $38, respectively, and other income of $18 million and $32 million, respectively. The increase in AFUDC-equity was primarily due to the timing of resiliency projects. The decrease in interest income from affiliate is due to the repayment of the note receivable from PGS for PGS's allocation of short-term and long-term debt resulting from the separation of PGS from TEC as of January 1, 2023. See Notes 1 and 10 to the TEC Consolidated Financial Statements for details of the separation of PGS from TEC and the resulting related party transactions. The decrease in Other Income is primarily due to lower interest income on the deferred fuel balance.

AFUDC-equity is expected to increase in 2025 due to the timing of construction of capital projects, including solar generation.

Interest Expense

For the years 2024 and 2023, TEC’s interest expense, including interest expense to affiliates and excluding AFUDC-debt, was $203 million and $245 million, respectively. The decrease in 2024 was due to lower borrowings resulting from proceeds received from affiliate loan repayments related to the separation of PGS from TEC in 2023 and lower fuel under-recoveries. In addition, the weighted-average interest rate on borrowings outstanding under the credit facilities and commercial paper at December 31, 2024 and 2023 was 4.8% and 5.7%, respectively. See Other Income above for information regarding the interest income from affiliate associated with PGS's allocation of short-term and long-term debt resulting from the separation of PGS from TEC as of January 1, 2023. The interest income from affiliate partially offsets the impact of TEC's interest expense within Net Income on the Consolidated Statement of Income.

Interest expense is expected to increase in 2025, reflecting higher balances (see Note 6 to the 2024 Annual TEC Consolidated Financial Statements for further detail).

Income Taxes

​The provision for income taxes decreased in 2024 compared to 2023 primarily as a result of lower pre-tax income and production tax credits related to solar facilities. Income tax expense as a percentage of income before taxes was 12.7% in 2024 and 15.7% in 2023. TEC expects the 2025 annual effective tax rate to be approximately 14%.

​ TEC is included in a consolidated U.S. federal income tax return with EUSHI and its subsidiaries. TEC’s income tax expense is based upon a standalone return method, modified for the benefits-for-loss allocation in accordance with EUSHI’s tax sharing agreement. The cash (refunds) payments for federal income taxes and state income taxes made under those tax sharing agreements totaled $(3) million and $102 million in 2024 and 2023, respectively.

Cash from Operating Activities

Cash flows from operating activities in 2024 were $1,164 million, a decrease of $77 million compared to 2023. The decrease to cash from operations was primarily due to the timing of fuel cost collection, partially offset by decreases to accounts receivable balances resulting from decreased fuel and 2022 storm cost recoveries reflected in customer bills and increases to accounts payable due to the timing of invoice payments.

Cash from Investing Activities

Cash flows from investing activities in 2024 resulted in a net use of cash of $1.4 billion, which primarily reflects TEC’s investment in capital. See the Capital Investments section for additional information.

Cash from Financing Activities

Cash flows from financing activities in 2024 resulted in net cash inflows of $254 million. TEC received $600 million of equity contributions from Parent and $495 million proceeds from the issuance of long-term debt. These increases in cash flows were partially offset by dividend payments to Parent of $469 million, the repayment of $300 million of long-term debt and a $70 million decrease in short-term debt with maturities of less than 90 days.

Cash and Liquidity Outlook

TEC’s tariff-based gross margins are the principal source of cash from operating activities. A diversified retail customer mix, primarily consisting of rate-regulated residential, commercial, and industrial customers, provides TEC with a reasonably predictable source of cash. In addition to using cash generated from operating activities, TEC uses available cash, equity contributions from Parent, credit facility and commercial paper borrowings, transactions with affiliates, and debt issuances to support normal operations and capital expenditure requirements. TEC may reduce short-term borrowings with cash from operations, long-term borrowings, or capital contributions from Parent. TEC expects to make significant capital expenditures in 2025 (see Capital Investments section below for further detail on TEC’s projected capital expenditures). Debt raised is subject to applicable regulatory approvals and Tampa Electric is required to maintain a capital structure as allowed by the regulator.

As noted earlier, cash from operating activities and short-term borrowings are used to fund normal operations and capital expenditures, which may result in periodic working capital deficits. The working capital deficit as of December 31, 2024 was primarily caused by short-term borrowings and periodic fluctuations in assets and liabilities related to FPSC clauses and riders. At December 31, 2024, TEC’s unused capacity under its credit facilities was $163 million.

TEC has a credit facility utilized with commercial paper that provides $800 million of credit, maturing in 2028. See Note 6 to the 2024 Annual TEC Consolidated Financial Statements for additional information regarding the credit facilities and commercial paper. TEC expects that its liquidity will be adequate for both the near and long term, given its expected operating cash flows, capital expenditures and related financing plans.

TEC expects cash from operations in 2025 to be lower than 2024 primarily due to higher cash outflow in 2025 for storm costs incurred in 2024, a decrease in expected fuel recoveries, and higher anticipated tax payments, offset by an increase in base rates

21

effective in January 2025, inflow of storm surcharge revenue and customer growth (see Note 3 to the 2024 Annual TEC Consolidated Financial Statements). TEC plans to use cash in 2025 to fund capital spending and to pay dividends to its shareholder. Dividends are paid at the discretion of TEC’s Board of Directors.

TEC’s credit facilities contain certain financial covenants (see Covenants in Financing Agreements section). TEC estimates that it could fully utilize the total available capacity under its facilities in 2025 and remain within the covenant restrictions.

(1)Borrowings outstanding are reported as notes payable in the Consolidated Balance Sheets.

(2)On April 1, 2024, TEC amended the credit facility agreement to extend the maturity date to December 1, 2028. TEC also has an active commercial paper program for up to $800 million, of which the full amount outstanding is backed by TEC’s credit facility. The amount of commercial paper issued results in an equal amount of its credit facility being considered drawn and unavailable. On January 30, 2024, TEC completed a sale of $500 million aggregate principal amount of 4.90% Notes due March 1, 2029. TEC used the net proceeds from this offering for the repayment of a portion of the borrowings outstanding under the credit facility. Therefore, $497 million of borrowings outstanding under the credit facility were reclassified as long-term debt on the Consolidated Balance Sheet as of December 31, 2023.

(3)On March 1, 2023, TEC entered into a 1-year term facility that matured on February 28, 2024.

(4)On April 3, 2023, TEC entered into a 1-year term facility that matured on April 1, 2024.

At December 31, 2024, the credit facility required a commitment fee of 12.5 basis points. The weighted average interest rate on outstanding amounts payable under the credit facilities and commercial paper program at December 31, 2024 and 2023 was 4.8% and 5.7%, respectively. For a complete description of the credit facilities see Note 6 to the 2024 Annual TEC Consolidated Financial Statements.

Significant Financial Covenants

In order to utilize its bank credit facilities, TEC must meet certain financial tests as defined in the applicable agreements. In addition, TEC has certain restrictive covenants in specific agreements and debt instruments. At December 31, 2024, TEC was in compliance with all applicable financial covenants. The table that follows lists the significant financial covenants and the performance relative to them at December 31, 2024. Reference is made to the specific agreements and instruments for more details.

Credit Ratings at December 31, 2024

22

	Standard & Poor’s (S&P)	Moody’s	Fitch
Credit ratings of senior unsecured debt	BBB+	A3	A
Credit ratings outlook	Negative	Negative	Negative

S&P, Moody’s and Fitch describe credit ratings in the A3 or A category as having a strong capacity to meet its financial commitments. Ratings in the BBB or Baa category are described as representing adequate capacity for payment of financial obligations. The lowest investment grade credit rating for S&P is BBB-, for Moody’s is Baa3 and for Fitch is BBB-; thus, the three credit rating agencies assign TEC’s senior unsecured debt investment-grade credit ratings.

In January 2025, S&P changed TEC's credit ratings outlook to Stable from Negative.

A credit rating agency rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency. TEC’s access to capital markets and cost of financing, including the applicability of restrictive financial covenants, are influenced by the ratings of its securities. In addition, certain of TEC’s derivative instruments contain provisions that require TEC’s debt to maintain investment grade credit ratings.

Summary of Contractual Obligations

The following table lists the contractual obligations of TEC, including cash payments to repay long-term debt, interest payments, lease payments and unconditional commitments related to capital expenditures.

Contractual Cash Obligations at December 31, 2024

(1)See the Consolidated Statements of Capitalization and Note 7 to the 2024 Annual TEC Consolidated Financial Statements for a list of long-term debt and the respective due dates.

(2)Future interest payments are calculated based on the assumption that all debt is outstanding until maturity. For debt instruments with variable rates, interest is calculated for all future periods using the rates in effect at December 31, 2024.

(3)These payment obligations under contractual agreements are recovered from customers under regulatory clauses approved by the FPSC (see the Business section).

(4)The estimated contractual obligation is calculated as required contributions to the funded pension plan and estimated benefit payments related to the other unfunded benefit plans. Under calculation requirements of the Pension Protection Act, as of the January 1, 2024 measurement date, the pension plan was fully funded. Under ERISA guidelines, TEC is not required to make additional cash contributions until 2027; however, TEC may elect to make discretionary cash contributions prior to that time. Future contributions are subject to annual valuation reviews, which may vary significantly due to changes in interest rates, discount rate assumptions, plan asset performance, which is affected by investment portfolio performance, and other factors (see Liquidity, Capital Resources section and Note 5 to the 2024 Annual TEC Consolidated Financial Statements).

(5)Represents outstanding commitments for major capital projects (see the Capital Investments section).

(6)Includes contractual obligations under demand side management and purchased power agreements.

(1)Individual line items exclude AFUDC-debt and equity.

Tampa Electric intends to invest approximately $599 million in 375 MW of new utility-scale solar photovoltaic projects in 2024 through 2026 (solar wave III) and approximately $812 million in 466MW of new utility-scale solar photovoltaic projects in 2026 through 2028 (solar wave IV). In 2024 through 2026, Tampa Electric expects to spend approximately $600 million in capital for the storm protection plan, $535 million in grid modernization, $350 million in its new corporate headquarters and operations center for building resilience, $94 million for 74 MW of generation capacity expansion and $156 million for 115 MW of energy storage. AFUDC will be earned on eligible capital projects during the construction periods and return on investment will be earned on capital projects running through certain recovery mechanisms.

Tampa Electric’s 2024 capital expenditures included solar generation projects, storm hardening for the transmission and distribution systems, new technology for distribution system grid modernization, energy storage, maintenance and refurbishment of existing generating facilities, a generation capacity expansion project and the construction of a new headquarters and operations center to improve building resilience. In 2025, Tampa Electric expects capital expenditures to include solar generation and energy storage projects, completion of a generation capacity expansion project to improve system resilience, a new headquarters and operations center to improve building resilience, storm hardening for the transmission and distribution systems, new technology for distribution system grid modernization, and the maintenance and refurbishment of existing generating facilities.

The forecasted capital expenditures shown above are based on current estimates and assumptions. Actual capital expenditures could vary materially from these estimates due to changes in and timing of projects and changes in costs for materials or labor (see the Risk Factors section).

Capital Structure

At December 31, 2024, TEC’s year-end capital structure was 46% debt and 54% common equity. At December 31, 2023, TEC’s year-end capital structure was 48% debt and 52% common equity.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of consolidated financial statements requires management to make various estimates and assumptions that affect revenues, expenses, assets, liabilities and disclosures. The policies and estimates identified below are, in the view of management, the more significant accounting policies and estimates used in the preparation of our consolidated financial statements. These estimates and assumptions are based on historical experience and on various other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates and judgments under different assumptions or conditions. See Note 1 to the 2024 Annual TEC Consolidated Financial Statements for a description of TEC’s significant accounting policies and the estimates and assumptions used in the preparation of the consolidated financial statements.

Regulatory Accounting

Tampa Electric’s retail business and the prices charged to customers are regulated by the FPSC. Tampa Electric’s wholesale business is regulated by the FERC. As a result, Tampa Electric qualifies for the application of accounting guidance for certain types of regulation. This guidance recognizes that the actions of a regulator can provide reasonable assurance of the existence of an asset or liability. Regulatory assets and liabilities arise as a result of a difference between U.S. GAAP and the accounting principles imposed by the regulatory authorities. Regulatory assets generally represent incurred costs that have been deferred, as their future recovery in customer rates is probable. Regulatory liabilities generally represent obligations to make refunds to customers from previous collections for costs that are not likely to be incurred.

TEC regularly assesses the probability of recovery of the regulatory assets by considering factors such as regulatory environment changes, recent rate orders to other regulated entities in the same jurisdiction, the current political climate in the state, and the status of any pending or potential deregulation legislation. The assumptions and judgments used by regulatory authorities will continue to have an impact on the recovery of costs, the rate earned on invested capital and the timing and amount of assets to be recovered.

TEC’s most significant regulatory liability relates to non-ARO costs of removal and regulatory tax liability. The non-ARO costs of removal represent estimated funds received from customers through depreciation rates to cover future non-legally required cost of removal of property, plant and equipment upon retirement. TEC accrues for removal costs over the life of the related assets based on depreciation studies approved by the FPSC. The costs are estimated based on historical experience and future expectations, including expected timing and estimated future cash outlays. The regulatory tax liability is the offset to the adjustment to the deferred tax liability remeasured as a result of tax reform. See Note 4 to the 2024 Annual TEC Consolidated Financial Statements for further information.

The application of regulatory accounting guidance is a critical accounting policy and estimate since a difference in these assumptions and actual results may result in a material impact on reported assets and the results of operations (see Note 3 to the 2024 Annual TEC Consolidated Financial Statements).

Income Taxes

​TEC uses the asset and liability method in the measurement of deferred income taxes. Under the asset and liability method, TEC estimates the current tax exposure and assesses the temporary differences resulting from differing treatment of items, such as depreciation, for financial statement and tax purposes. These differences are reported as deferred taxes measured at enacted rates in the consolidated financial statements. Management reviews all reasonably available current and historical information, including forward-looking information, to determine if it is more likely than not that some or the entire deferred tax asset will not be realized. If TEC determines that it is likely that some or all of a deferred tax asset will not be realized, then a valuation allowance is recorded to report the balance at the amount expected to be realized. At December 31, 2024, TEC does not have a valuation allowance. At December 31, 2024, TEC had a net deferred income tax liability of $976 million, attributable primarily to property-related items.

​See further discussion of uncertainty in income taxes, impacts of tax reform and other tax items in Note 4 to the 2024 Annual TEC Consolidated Financial Statements.

Employee Postretirement Benefits

TEC is a participant in the retirement plans of TECO Energy. TECO Energy sponsors a defined benefit pension plan (pension plan), a fully-funded non-qualified, non-contributory supplemental executive retirement benefit plan available to certain members of senior management and an unfunded non-qualified, non-contributory Restoration Plan that allows certain members of senior management to receive an additional benefit to restore what is limited by the IRS under the pension plan. TEC recognizes in its statement of financial position the over-funded or under-funded status of its allocated portion of TECO Energy’s postretirement benefit plans. The accounting related to employee postretirement benefits is a critical accounting estimate for TEC for the following reasons: 1) a change in the estimated benefit obligation could have a material impact on reported assets, liabilities and results of

25

operations; and 2) changes in assumptions could change the annual pension funding requirements, which could have a significant impact on TEC’s annual cash requirements.

Several statistical and other factors which attempt to anticipate future events are used in calculating the expenses and liabilities related to these plans. Key factors include assumptions about the expected rates of return on plan assets, discount rates and mortality rates. TECO Energy determines these factors within certain guidelines and with the help of external consultants. TECO Energy considers market conditions, including but not limited to, changes in investment returns and interest rates, in making these assumptions.

Pension plan assets (plan assets) are invested in a mix of equity and fixed-income securities. The expected return on asset assumption was based on expectations of long-term inflation, real growth in the economy, fixed income spreads and equity premiums consistent with the company’s portfolio, with provision for active management and expenses paid from the trust that holds the plan assets. The expected return on assets was 7.05%, 7.05% and 6.50% as of January 1, 2024, 2023 and 2022, respectively. Given recent capital market returns and market expectations for long-term interest rates, TECO Energy expects the expected return on assets to be 7.05% for 2025 (based on 20-year expected market returns). Actual returns in 2024 were 5.1%.

The discount rate assumption used to measure benefit expense was an above-mean yield curve. The above-mean yield curve technique matches the yields from 100 high-quality (AA-rated, non-callable) corporate bonds to the company’s projected cash flows for the plans to develop a present value that is converted to a discount rate assumption, which is subject to change each year.

Holding all other assumptions constant, a 1% decrease in the assumed rate of return on pension plan assets or the discount rate assumption would have had in 2024 and is anticipated to have in 2025 the following impact on TEC’s after-tax pension cost:

Year	1% Decrease in Assumed Expected Return on Assets	1% Decrease in Assumed Discount Rate
2024	$6 million increase	$1 million increase
2025	$6 million increase	$1 million increase

Unrecognized actuarial gains and losses for the pension plan are being recognized over a period of approximately 12 years, which represents the expected remaining service life of the employee group. Unrecognized actuarial gains and losses arise from several factors including experience and assumption changes in the obligations and from the difference between expected return and actual returns on plan assets. These unrecognized gains and losses will be systematically recognized in future net periodic pension expense in accordance with applicable accounting guidance for pensions.

The key assumptions used in determining the amount of obligation and expense recorded for postretirement benefits other than pension (OPEB), under the applicable accounting guidance, include the assumed discount rate and the assumed rate of increases in future health care costs. TECO Energy determines the discount rate for the OPEB’s projected benefit cash flows. In estimating the health care cost trend rate, TECO Energy considers its actual health care cost experience, future benefit structures, industry trends, and advice from our outside actuaries.

See the discussion of employee postretirement benefits in Note 5 to the 2024 Annual TEC Consolidated Financial Statements.

RECENTLY ISSUED ACCOUNTING STANDARDS

Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures. The change in the standard improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The changes improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. The guidance was effective for annual reporting periods beginning after December 15, 2023, and for interim periods

26

beginning after December 15, 2024. TEC adopted the standard for the year ended December 31, 2024. The standard was applied retrospectively. See Note 11 to the 2024 Annual TEC Consolidated Financial Statements for further detail.

Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The standard enhances the transparency, decision usefulness and effectiveness of income tax disclosures by requiring consistent categories and greater disaggregation of information in the reconciliation of income taxes computed using the enacted statutory income tax rate to the actual income tax provision and effective income tax rate, as well as the disaggregation of income taxes paid (refunded) by jurisdiction. The standard also requires disclosure of income (loss) before provision for income taxes and income tax expense (benefit) in accordance with U.S. Securities and Exchange Commission (SEC) Regulation S-X 210.4-08(h), Rules of General Application – General Notes to Financial Statements: Income Tax Expense, and the removal of disclosures no longer considered cost beneficial or relevant. The guidance will be effective for annual reporting periods beginning after December 15, 2024, and interim periods within annual reporting periods beginning after December 15, 2025. Early adoption is permitted. The standard will be applied on a prospective basis, with retrospective application permitted. TEC is currently evaluating the impact of adoption of the standard on its financial statement disclosures.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting–Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses. The standard update improves the disclosures about a public business entity’s expenses by requiring more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation and amortization) included within income statement expense captions. The guidance will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The standard will be applied on a prospective basis, with retrospective application permitted. TEC is currently evaluating the impact of adoption of the standard on its financial statement disclosures.

ENVIRONMENTAL COMPLIANCE

Environmental Matters

TEC has significant environmental considerations. Tampa Electric operates stationary sources with air emissions regulated by the Clean Air Act. Its operations are also impacted by provisions in the Clean Water Act and federal and state legislative initiatives on environmental matters.

Carbon Reductions and GHG

Tampa Electric has historically supported voluntary efforts to reduce carbon emissions and has taken significant steps to reduce overall emissions at Tampa Electric’s facilities. Since 2000, Tampa Electric has reduced its system-wide emissions of CO2 by more than 50%, bringing emissions to below 1990 levels. Tampa Electric CO2 emissions continue to remain below 1990 levels. In addition to the emission decreases in 2005 as the result of the repowering of two Gannon Station coal units to natural gas and the shut-down of the remaining Gannon Station coal-fired units, Tampa Electric has optimized its existing coal units to operate on natural gas. During this same time frame, the number of retail customers and retail energy sales have risen. Tampa Electric also substantially reduced CO2 emissions by significantly expanding the use of solar power, repowering Big Bend Unit 1 steam turbine, and retiring Big Bend Unit 2 and Unit 3. The Big Bend Unit 1 modernization project is capable of producing 1,090 megawatts of power and will continue to lead to lower system-wide emissions. See Capital Investments above for information regarding Tampa Electric’s solar projects.

On April 24, 2024, the EPA issued its final power plant rules for electric generating units, including (i) new GHG standards and (ii) Mercury and Air Toxics Standards (MATS). The new MATS will not have a material impact on TEC. The new GHG standard applies only to existing coal-fired and new natural gas electric generating units and will therefore have limited impact on Tampa Electric generating units. Big Bend Unit 4 is the only unit affected. As written, the rule would require Big Bend Unit 4 to retire in 2039 without major enhancements to the unit, instead of the current planned retirement date of 2040.

Coal Combustion Residuals Recycling and Regulation

Tampa Electric produces ash and other by-products, collectively known as CCRs at its Big Bend Power Station. Greater than 90% of all CCRs produced at this facility are marketed to customers for beneficial use in commercial and industrial products. The EPA’s final CCR rule became effective on October 19, 2015 and regulates CCRs as non-hazardous solid waste. In 2016 and 2017, the FPSC approved Environmental Cost Recovery for capital and O&M expenses associated with various projects proposed as part of  Tampa Electric’s CCR compliance program. Subsequently, a closure by removal and liner retrofit project for the West Slag

27

Dewatering Pond was completed in 2020 and closure by removal of all CCRs from the Economizer Ash and Pyrite Ponds was completed in October 2021. The final project required for compliance with the CCR Rule at Big Bend is the North Gypsum Stackout Area Drainage Improvements Project, which is scheduled for completion in 2025. FDEP has revised the existing state solid waste regulation to incorporate Florida CCR permit requirements for regulated units and these new requirements will operate in lieu of the Federal permitting program. However, TEC is largely exempt from the state permitting requirements because it completed its mandatory closure projects prior to the state rule’s passage. On May 18, 2023, the EPA proposed new rules requiring identification and regulation of Legacy CCR Management Units. TEC is a member of the Utility Solid Waste Activities Group, who filed comments on behalf of its members in July 2023 contesting many of the proposed rule’s provisions.

The new CCR rule finalized in April 2024 covers any landfill or impoundment in existence at an inactive power facility but not receiving CCRs as of 2015, any CCR placed into the environment for beneficial uses, or CCR units (landfills and impoundments) previously closed under state programs. TEC is currently evaluating the impact of the new CCR rule at the Big Bend Power Station and will likely require site evaluations beginning in 2025 to determine the presence or absence of CCR management units. If found, additional evaluations would be required in 2026 and based on those findings, modifications to the site groundwater monitoring could be required beginning in 2027 to determine the need for additional corrective action.

TEC expects that the costs to comply with the new environmental regulations would be eligible for recovery. If approved as prudent, the costs would be reflected in customers’ bills, recovered through either the environmental cost recovery clause or base rates.   

Water Supply and Quality

The EPA’s final rule under 316(b) of the Clean Water Act (effective October 2014) addresses perceived impacts to aquatic life by cooling water intakes and is applicable to Tampa Electric's Bayside and Big Bend Power Stations. Polk Power Station is not covered by this rule since it does not operate an intake on "waters of the United States". Tampa Electric has two ongoing projects (one for Bayside and one for Big Bend) that require compliance with the rule. Compliance includes the completion of the biological, technical, and financial study elements required by the rule. These study elements have been completed and submitted for Bayside and were used by FDEP to determine the necessity of cooling water system retrofits. FDEP agreed with Tampa Electric’s proposed plan for Bayside and Tampa Electric began a multi-year construction project to install new fish-friendly modified traveling screens and a fish return in 2022. Tampa Electric is negotiating an alternative schedule for Big Bend (as allowed by the rule) but completed a portion of the compliance requirements with the Big Bend modernization project with the installation of fish-friendly modified traveling screens and a fish return on modernized Unit 1. The remainder of the compliance requirements are to be determined and completed at a later date. The full impact of the new regulations on Tampa Electric will depend on the study elements performed as part of the rules’ implementation, and the actual requirements established by FDEP.

The final EPA rule for existing steam electric effluent limit guidelines (ELGs) became effective January 4, 2016 and establishes limits for wastewater discharges from flue gas desulfurization (FGD) processes, fly ash and bottom ash transport water, leachate from ponds and landfills containing coal combustion residuals, gasification processes, and flue gas mercury controls. The new ELGs will not have a material impact on TEC. Big Bend completed construction of a deep injection well system in December 2023 for disposal of FGD wastewater, bottom ash transport water and other process wastewaters rather than discharge to surface waters. This change will be made to the final National Pollutant Discharge Elimination System (NPDES) permit, anticipated in 2025. Since Polk Power Station also uses a deep injection well rather than discharging it to surface water, the effluent limitations will no longer apply to either power station. The referenced wastewaters at each power station will be regulated under the Underground Injection Control program rather than the NPDES program.

EPA Waters of the US

In 2023, the EPA and Department of the Army issued a final rule amending the definition of “waters of the United States”. The final rule is expected to have environmental permitting implications for new Tampa Electric solar sites and permitting renewals for existing facilities requiring approved jurisdictional determinations.

Ozone

On December 31, 2020, the EPA published a final rule to retain the national ambient air quality standards (NAAQS) for photochemical oxidants including ozone, originally adopted in 2012. Under the Clean Air Act, the EPA is required to review the NAAQS every five years and, if appropriate, revise it. The EPA has announced that the NAAQS is currently under review, which could result in revisions to the standard affecting compliance in Tampa Electric’s service territory. The impact of this potential new standard on the operations of Tampa Electric will depend on the standard that is ultimately adopted and on the outcome of any related litigation or other developments.

28

Superfund and Former Manufactured Gas Plant Sites

As of December 31, 2022, TEC, through its Tampa Electric division and former PGS division, was a PRP for certain superfund sites and, through its former PGS division, for certain former MGP sites. As a result of the separation of the PGS division, PGS is now the responsible party for those sites (in addition to third party PRPs for certain sites). See Note 1 to the 2024 Annual TEC Consolidated Financial Statements for information regarding the separation of PGS from TEC.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Risk Management Infrastructure

TEC is subject to various types of market risk in the course of daily operations, as discussed below. TEC has adopted an enterprise-wide approach to the management and control of market and credit risk. Middle Office risk management functions, including credit risk management and risk control, are independent of each transacting entity (Front Office).

TECO Holding’s Risk Management Policy (Policy) governs all energy transacting activity. The Policy is administered by a Risk Authorizing Committee (RAC) that is comprised of senior management. Within the bounds of the Policy, the RAC approves specific hedging strategies, new transaction types or products, limits, and transacting authorities. Transaction activity is reported daily and measured against limits. For all commodity risk management activities, derivative transaction volumes are limited to the anticipated volume for customer sales or supplier procurement activities.

TEC operates and oversees transaction activity related to interest rate risk exposures. Interest rate derivative transaction activity is directly correlated to borrowing activities.

Risk Management Objectives

The Front Office is responsible for reducing and mitigating the market risk exposures that arise from the ownership of physical assets and contractual obligations. The primary objectives of the risk management organization, the Middle Office, are to quantify, measure, and monitor the market risk exposures arising from the activities of the Front Office and the ownership of physical assets. In addition, the Middle Office is responsible for enforcing the limits and procedures established under the approved risk management policies. Based on the policies approved by TEC’s board of directors and the procedures established by the RAC, from time to time, TEC enters into futures, forwards, swaps and option contracts to limit the exposure to items, such as fuel supply risk and the risk of price fluctuations for physical purchases and sales of natural gas in the course of normal operations.

TEC uses derivatives only to reduce normal operating and market risks, not for speculative purposes. The primary objective in using derivative instruments for regulated operations is to reduce the impact of market price volatility on customers.

On November 6, 2017, the FPSC approved an amended and restated settlement agreement filed by Tampa Electric, which includes a provision for a moratorium on hedging of natural gas purchases ending on December 31, 2022. On October 21, 2021, the FPSC approved a settlement agreement filed by Tampa Electric related to its 2021 rate case that extended the moratorium to December 31, 2024 (see Note 3 to the 2024 Annual TEC Consolidated Financial Statements for further information on the settlement agreements). As of December 31, 2024 and 2023, TEC had no hedges in place.

Credit Risk

TEC has a rigorous process for the establishment of new trading counterparties and evaluation of current counterparties. This process includes an evaluation of each counterparty’s credit ratings, as applicable, and/or its financial statements, with attention paid to liquidity and capital resources; establishment of counterparty specific credit limits; optimization of credit terms; and execution of standardized enabling agreements. TEC manages credit risk with policies and procedures for counterparty analysis, exposure measurement, and exposure monitoring and mitigation. Credit assessments are conducted on all counterparties, and deposits or collateral are requested for counterparties that do not meet the creditworthiness requirements as set out in TEC's internal policies.

29

Certain of TEC’s derivative instruments, including NPNS agreements, contain provisions that require TEC's debt to maintain an investment-grade credit rating from any or all of the major credit rating agencies. If TEC’s debt ratings were to fall below investment grade or not be rated, it could trigger these provisions, and the counterparties to the derivative instruments could demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions.

Interest Rate Risk

TEC is exposed to changes in interest rates primarily from borrowing under the company's credit facilities and commercial paper program. A hypothetical 10% increase in TEC's weighted-average interest rate on its borrowings under the credit facilities and commercial paper outstanding at December 31, 2024 and 2023 would have resulted in a $1 million and $6 million impact on pre-tax earnings, respectively. This is driven by lower outstanding balances and interest rates. A hypothetical 10% increase in interest rates would have decreased the fair market value of TEC's long-term debt by 6% at December 31, 2024 and December 31, 2023. See the Financing Activity section and Notes 6 and 7 to the 2024 Annual TEC Consolidated Financial Statements. These amounts were determined based on the variable rate obligations existing on the indicated dates at TEC. The above sensitivities assume no changes to TEC’s current financial structure and could be affected by changes in TEC’s credit ratings, changes in general economic conditions or other external factors (see the Risk Factors section).

Commodity Risk

TEC faces varying degrees of exposure to commodity risks including natural gas, coal and other energy commodity prices. Any changes in prices could affect the prices TEC charges, its operating costs and the competitive position of its products and services. Management uses different risk measurement and monitoring tools based on the degree of exposure to commodity risks.

Regulated Utilities

Tampa Electric’s fuel costs used for generation are affected primarily by the price of natural gas and, to a lesser degree, the cost of coal (see the Business - Generation Sources section). Currently, TEC’s commodity price risks are largely mitigated by the fact that increases in the price of prudently incurred fuel and purchased power are recovered through FPSC-approved cost-recovery clauses, with no anticipated effect on earnings. However, increasing fuel cost-recovery has the potential to affect the relative attractiveness of alternative energy solutions to consumers. TEC manages fuel supply risk and commodity price risk by entering into long-term fuel supply agreements and prudently operating plant facilities to optimize cost. At December 31, 2024 and 2023, a change in commodity prices would not have had a material impact on TEC's earnings but could have and has had an impact on the timing of the cash recovery of the cost of fuel.

TAMPA ELECTRIC COMPANY

Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Shareholder and the Board of Directors of Tampa Electric Company

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Tampa Electric Company (the Company) as of December 31, 2024 and 2023, the related consolidated statements of income and comprehensive income, capitalization and cash flows for each of the three years in the period ended December 31, 2024, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

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

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

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

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated 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.

Accounting for the effects of regulatory matters

Description of the Matter

As of December 31, 2024, the Company had $1,441 million in regulatory assets and $904 million in regulatory liabilities. As disclosed in Note 3 of the consolidated financial statements, Tampa Electric’s retail business is regulated by the Florida Public Service Commission (FPSC), and Tampa Electric is also subject to regulation by the Federal Energy Regulatory Commission (FERC) (collectively, the regulators). The regulatory rates are designed to recover the prudently incurred costs of providing service or products, plus a reasonable return on equity invested or assets. In addition to regulatory assets and liabilities, rate regulation impacts other financial

31

statement balances and activity, including, but not limited to, property, plant, and equipment, revenues, and expenses. Auditing the impact of rate regulation on the Company’s consolidated financial statements is complex due to the significant judgments made by the Company to support its accounting and disclosure for regulatory matters when final regulatory decisions or orders have not yet been made or when regulatory formulas are vague or complex. There is also subjectivity involved in assessing the potential impact of future regulatory decisions on the financial statements. Although the Company expects to recover costs from customers through rates, there is a risk that the regulators may not approve full recovery of costs incurred. The Company’s judgments include making an assessment of the probable recovery of, and return on, costs incurred, of the potential disallowance of part of the cost incurred, or of the probable refund to customers through future rates.

How We Addressed the Matter in Our Audit

We tested the Company’s evaluation of the probability of future recovery for regulatory assets and refund of regulatory liabilities for regulatory matters when final regulatory decisions or orders have not yet been made or when regulatory formulas are vague or complex. Our audit procedures included, among others, obtaining and reviewing relevant regulatory orders, filings, and other correspondence. We inspected these communications for any evidence that might contradict the Company’s assertions. We reviewed regulatory orders, filings, and other correspondence for other entities within the same jurisdiction or for the Company’s previously approved regulatory assets and liabilities to assess the likelihood of recovery in future rates based on the regulators’ treatment of similar costs under similar circumstances. We also assessed the methodology, accuracy and completeness of the Company’s calculations of regulatory asset and liability balances based on provisions and formulas outlined in regulatory orders, filings, and other correspondence with the regulators. We also evaluated the Company's disclosures related to the impacts of rate regulation including the balances recorded and the regulatory developments.

TEC is comprised of the electric division, referred to as Tampa Electric, and prior to January 1, 2023, also included the natural gas division, referred to as PGS. Tampa Electric provides retail electric services in West Central Florida, and PGS is engaged in the purchase, distribution and sale of natural gas for residential, commercial, industrial and electric power generation customers in Florida. Prior to January 1, 2023, intercompany balances and transactions within the electric and natural gas divisions have been eliminated in consolidation. See "Separation of PGS from TEC" below for information regarding the separation that occurred on January 1, 2023. TEC’s significant accounting policies are as follows:

Principles of Consolidation and Basis of Presentation

TEC maintains its accounts in accordance with recognized policies prescribed or permitted by the FPSC and the FERC. These policies conform with U.S. GAAP in all material respects. The use of estimates is inherent in the preparation of financial statements in accordance with U.S. GAAP. Actual results could differ from these estimates.

Prior to April 1, 2024, TEC was a wholly owned subsidiary of TECO Energy, which is an indirect, wholly owned subsidiary of Emera. On April 1, 2024, TECO Energy distributed its investment in TEC to TECO Holdings, Inc. in a transaction intended to qualify as a tax-free reorganization. This new corporation is also an indirect, wholly owned subsidiary of Emera. Therefore, TEC is an indirect, wholly owned subsidiary of Emera.

Cash Equivalents

Cash equivalents are highly liquid, high-quality investments purchased with an original maturity of three months or less. The carrying amount of cash equivalents approximated fair market value because of the short maturity of these instruments.

Property, Plant and Equipment

Property, plant and equipment is stated at original cost, which includes labor, material, applicable taxes, overhead and AFUDC. Concurrent with a planned major maintenance outage or with new construction, the cost of adding or replacing retirement units-of-property is capitalized in conformity with the regulations of FERC and FPSC. The cost of maintenance, repairs and replacement of minor items of property is expensed as incurred.

As a regulated utility, TEC must file depreciation and dismantlement studies periodically and receive approval from the FPSC before implementing new depreciation rates. Included in approved depreciation rates is either an implicit net salvage factor or a cost of removal factor, expressed as a percentage. The net salvage factor is principally comprised of two components—a salvage factor and a cost of removal or dismantlement factor. TEC uses current cost of removal or dismantlement factors as part of the estimation method to approximate the amount of cost of removal in accumulated depreciation. The original cost of utility plant retired or otherwise disposed of and the cost of removal or dismantlement, less salvage value, is charged to accumulated depreciation and the accumulated cost of removal reserve reported as a regulatory liability, respectively.

For other property dispositions, the cost and accumulated depreciation are removed from the balance sheet and a gain or loss is recognized.

40

Property, plant and equipment consisted of the following assets:

(millions)	Estimated Useful Lives	December 31, 2024			December 31, 2023
Electric generation	10-60 years	$	6,574		$	6,732
Electric transmission	10-75 years		1,245			1,182
Electric distribution	10-60 years		3,920			3,609
General plant and other	4-60 years		1,081			997
Total cost			12,820			12,520
Less accumulated depreciation			(3,348	)		(3,443	)
Construction work in progress			1,631			1,151
Total property, plant and equipment, net		$	11,103		$	10,228

Depreciation

The provision for total regulated utility plant in service, expressed as a percentage of the original cost of depreciable property, was 3.6%, 3.5% and 3.2% for 2024, 2023 and 2022, respectively. Construction work in progress is not depreciated until the asset is placed in service. TEC's total depreciation expense for the years ended December 31, 2024, 2023 and 2022 was $417 million, $390 million and $402 million, respectively. For the year ended December 31, 2024, 2023 and 2022, Tampa Electric's depreciation expense was $417 million, $390 million and $359 million, respectively.

TEC computes depreciation and amortization using the following methods:

•the group remaining life method, approved by the FPSC, is applied to the average investment, adjusted for anticipated costs of removal less salvage, in functional classes of depreciable property;

•the amortizable life method, approved by the FPSC, is applied to the net book value to date over the remaining life of those assets not classified as depreciable property above.

Allowance for Funds Used During Construction

AFUDC is a non-cash credit to income with a corresponding charge to utility plant which represents the cost of borrowed funds and a reasonable return on other funds used for construction. The rates used to calculate AFUDC are revised periodically to reflect significant changes in cost of capital. In 2024, 2023 and 2022, Tampa Electric’s rate was 6.07%, 6.07% and 6.00%, respectively. PGS’s rate used to calculate its AFUDC in 2022 was 6.00%. Total AFUDC for the years ended December 31, 2024, 2023 and 2022 was $40 million, $25 million and $46 million, respectively.

Inventory

TEC values materials, supplies and fossil fuel inventory (natural gas and coal) using a weighted-average cost method. These materials, supplies and fuel inventories are carried at the lower of weighted-average cost or net realizable value.

Regulatory Assets and Liabilities

TEC is subject to accounting guidance for the effects of certain types of regulation (see Note 3).

Government Assistance

Government assistance is recognized when there is reasonable assurance that TEC will comply with the conditions and the funding will be received. Government assistance related to PP&E is deducted from the asset's carrying amount and the net amount is depreciated. Government assistance related to income is deducted from the related expense to which it is intended to compensate.

In 2024 and 2023, TEC received $5 million and zero, respectively, of government assistance from the U.S. Department of Energy towards the front end engineering design studies for carbon capture and storage. The capital projects receiving government assistance are related to TEC’s environmental compliance initiatives. Further details on significant government assistance programs are noted below.

41

Carbon Storage Project

In January 2025, TEC was approved for government assistance from the Department of Energy to fund an evaluation related to subsurface storage of CO2 in Florida. TEC can make claims for 80% of eligible project costs to a maximum $98 million. The term of the agreement ends on April 2028.

​Deferred Income Taxes

​TEC uses the asset and liability method in the measurement of deferred income taxes. Under the asset and liability method, the temporary differences between the financial statement and tax bases of assets and liabilities are reported as deferred taxes measured at enacted tax rates. TEC is regulated, and the books and records reflect approved regulatory treatment, including certain adjustments to accumulated deferred income taxes and the establishment of a corresponding regulatory tax liability reflecting the amount payable to customers through future rates. See Note 4 for additional details.

​Investment and Production Tax Credits (PTCs)

​ITCs have been recorded as deferred credits and are being amortized as reductions to income tax expense as required by regulatory practices. TEC recognizes a reduction of income tax expense for PTCs earned by its eligible solar assets. The PTCs are based on per kwH rate prescribed by applicable federal statutes.

​Stranded Tax Effects in Accumulated Other Comprehensive Income

​TEC utilizes a portfolio approach to determine the timing and extent to which stranded income tax effects from items that were previously recorded in accumulated other comprehensive income are released.

Revenue Recognition

Regulated electric revenue

Electric revenues, including energy charges, demand charges, basic facilities charges and applicable clauses and riders, are recognized when obligations under the terms of a contract are satisfied. This occurs primarily when electricity is delivered to customers over time as the customer simultaneously receives and consumes the benefits of the electricity. Electric revenues are recognized on an accrual basis and include billed and unbilled revenues. Revenues related to the sale of electricity are recognized at rates approved by the respective regulator and recorded based on metered usage, which occur on a periodic, systematic basis, generally monthly. At the end of each reporting period, the electricity delivered to customers, but not billed, is estimated and the corresponding unbilled revenue is recognized. Tampa Electric’s estimate of unbilled revenue at the end of the reporting period is calculated by estimating the number of MWH delivered to customers at the established rate expected to prevail in the upcoming billing cycle. This estimate includes assumptions as to the pattern of energy demand, timing of meter reads and line losses.

Regulated gas revenue

Prior to January 1, 2023, gas revenues, including energy charges, demand charges, basic facilities charges and applicable clauses and riders, were recognized when obligations under the terms of a contract were satisfied. This occurred primarily when gas was delivered to customers over time as the customer simultaneously received and consumed the benefits of the gas. Gas revenues were recognized on an accrual basis and included billed and unbilled revenues. Revenues related to the distribution and sale of gas were recognized at rates approved by the regulator and recorded based on metered usage, which occurred on a periodic, systematic basis, generally monthly. At the end of each reporting period, the gas delivered to customers, but not billed, was estimated and the corresponding unbilled revenue was recognized. PGS’s estimate of unbilled revenue at the end of the reporting period was calculated by estimating the number of therms delivered to customers at the established rate expected to prevail in the upcoming billing cycle. This estimate included assumptions as to the pattern of usage, weather, and inter-period changes to customer classes.

Other

See Accounting for Franchise Fees and Gross Receipts below for the accounting for gross receipts taxes. Sales and other taxes TEC collects concurrent with revenue-producing activities are excluded from revenue.

Revenues and Cost Recovery

Revenues include amounts resulting from cost-recovery clauses which provide for monthly billing charges to reflect increases or decreases in fuel, purchased power, conservation, environmental and storm protection plan costs for Tampa Electric and, prior to January 1, 2023, purchased gas, interstate pipeline capacity, replacement of cast iron/bare steel pipe and conservation costs for PGS. These adjustment factors are based on costs incurred and projected for a specific recovery period. Any over- or under-recovery of

42

costs plus an interest factor are taken into account in the process of setting adjustment factors for subsequent recovery periods. Over-recoveries of costs are recorded as regulatory liabilities, and under-recoveries of costs are recorded as regulatory assets.

Certain other costs incurred by the regulated utilities are allowed to be recovered from customers through prices approved in the regulatory process. These costs are recognized as the associated revenues are recognized.

Receivables and Allowance for Credit Losses

Receivables on the Consolidated Balance Sheets include receivables from contracts with customers, which consist of services to residential, commercial, industrial and other customers, totaling $219 million and $284 million as of December 31, 2024 and 2023, respectively. An allowance for credit losses is established based on TEC’s collection experience and reasonable and supportable forecasts that affect the collectibility of the reported amount. Circumstances that impact estimates of credit losses include, but are not limited to, customer credit issues, fuel prices, customer deposits and general economic conditions. Accounts are reserved in the allowance or written off once they are deemed to be uncollectible.

TEC accrues base revenues for services rendered but unbilled to provide for matching of revenues and expenses (see Note 3). As of December 31, 2024 and 2023, unbilled revenues of $68 million and $63 million, respectively, are included in the “Receivables” line item on TEC’s Consolidated Balance Sheets.

Accounting for Franchise Fees and Gross Receipts Taxes

TEC is allowed to recover certain costs incurred on a dollar-for-dollar basis from customers through rates approved by the FPSC. The amounts included in customers’ bills for franchise fees and gross receipt taxes are included as revenues on the Consolidated Statements of Income. Franchise fees and gross receipt taxes payable are included as an expense on the Consolidated Statements of Income in “Taxes, other than income”. These amounts totaled $120 million, $139 million and $145 million for the years ended December 31, 2024, 2023 and 2022, respectively.

Deferred Charges and Other Assets

Deferred charges and other assets consist primarily of pension assets net of accrued pension liabilities (see Note 5) and right-of-use assets related to operating leases (see Note 13).

Deferred Credits and Other Liabilities

Other deferred credits primarily include accrued other postretirement benefits (see Note 5), asset retirement obligations (see Note 12), lease liabilities (see Note 13) and a reserve for auto, general and workers’ compensation liability claims.

TECO Holdings and its subsidiaries, including TEC, have a self-insurance program supplemented by excess insurance coverage for the cost of claims whose ultimate value exceeds the company’s retention amounts. TEC estimates its liabilities for auto, general and workers’ compensation using discount rates mandated by statute or otherwise deemed appropriate for the circumstances. Discount rates used in estimating these other self-insurance liabilities at December 31, 2024 and 2023 ranged from 4.00% to 5.11% and 4.00% to 5.99%, respectively.

Derivatives and Hedging Activities

TEC had $1 million and $1 million derivative assets as of December 31, 2024 and 2023, respectively, and zero derivative liabilities as of December 31, 2024 and December 31, 2023, respectively.

TEC’s physical contracts qualify for the NPNS exception to derivative accounting rules, provided they meet certain criteria. Generally, NPNS applies if TEC deems the counterparty creditworthy, if the counterparty owns or controls resources within the proximity to allow for physical delivery of the commodity, if TEC intends to receive physical delivery and if the transaction is reasonable in relation to TEC’s business needs. As of December 31, 2024 and 2023, all of TEC’s physical contracts qualified for the NPNS exception, which was elected.

TEC classifies cash inflows and outflows related to derivative and hedging instruments in the appropriate cash flow sections associated with the item being hedged. For natural gas, the cash inflows and outflows are included in the operating section of the Consolidated Statements of Cash Flows. For interest rate swaps that settle coincident with the debt issuance, the cash inflows and outflows are treated as premiums or discounts and included in the financing section of the Consolidated Statements of Cash Flows.

Separation of PGS from TEC

PGS became an operating division of TEC in 1997 when TECO Energy purchased PGS and merged that corporation into TEC. Since then, PGS has operated as a stand-alone regulated utility, including having its own tariff and its own books and records.

43

On January 1, 2023, TEC transferred the assets and liabilities of its PGS division into a separate corporation called Peoples Gas System, Inc. (PGSI) pursuant to a Contribution Agreement. This new corporation is a wholly owned subsidiary of a newly formed gas operations holding company, TECO Gas Operations, Inc., a wholly owned subsidiary of TECO Energy. On January 1, 2023, the assets, liabilities, and equity that had been recorded in the books of PGS were transferred from TEC to the newly formed PGSI at book value in a tax-free transaction. PGSI issued 100 shares of common stock to TEC related to the transfer of PGS, which were subsequently distributed to TECO Energy, Inc. and then contributed to TECO Gas Operations, Inc. This is a transaction between entities under common control; therefore, TEC did not recognize a gain or loss on the transaction. TEC is not required to recast its prior period financial statements and disclosures to exclude PGS prior to January 1, 2023. The TEC Consolidated Statement of Cash Flows for the year ended December 31, 2023 does not include the non-cash impact of separating the PGS assets, liabilities and equity from TEC on January 1, 2023 and excludes PGS’s opening cash balance.

The impact of the separation of PGS from TEC on the Consolidated Statements of Capital for the year ended December 31, 2023 was $992 million, which represents the net assets of PGS transferred as of January 1, 2023. TEC recorded $121 million to retained earnings, which was the retained earnings of PGS as of January 1, 2023, and the remainder of $871 million was recorded to additional paid in capital, which is presented with common stock.

Prior to the separation, as a division of TEC, PGS had received an allocation of outstanding unsecured notes and outstanding short-term borrowings issued by TEC. The obligations related to these combined borrowings were reflected in an affiliate loan agreement between TEC and PGS. The initial obligation of PGS under the loan agreement at January 1, 2023 was a term loan in the principal amount of $670 million and a revolving loan in the principal amount of $66 million. The maturity date for both was December 29, 2023. On December 20, 2023, PGS repaid Tampa Electric the outstanding principal amount of the term loan and revolving loan of $670 million and $286 million, respectively, plus outstanding interest. The repayment terminates the affiliate loan agreement and Tampa Electric will no longer provide capital for the operations of PGS. See Note 6 for further information.

See Note 11 for certain financial information related to PGS. In addition, the following table presents the assets and liabilities of PGS in TEC’s Consolidated Balance Sheet as of December 31, 2022:

2. New Accounting Pronouncements

Reportable Segment Disclosures

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures. The change in the standard improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The changes improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. The guidance was effective for annual reporting periods beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. TEC adopted the standard for the year ended December 31, 2024. The standard was applied retrospectively. See Note 11 for further detail.

Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The standard enhances the transparency, decision usefulness and effectiveness of income tax disclosures by requiring consistent categories and greater disaggregation of information in the reconciliation of income taxes computed using the enacted statutory income tax rate to the actual income tax provision and effective income tax rate, as well as the disaggregation of income taxes paid (refunded) by jurisdiction. The standard also requires disclosure of income (loss) before provision for income taxes and income tax expense (benefit) in accordance with U.S. Securities and Exchange Commission (SEC) Regulation S-X 210.4-08(h), Rules of General Application – General Notes to Financial Statements: Income Tax Expense, and the removal of disclosures no longer considered cost beneficial or relevant. The guidance will be effective for annual reporting periods beginning after December 15, 2024, and interim periods within annual reporting periods beginning after December 15, 2025. Early adoption is permitted. The standard will be applied on a prospective basis, with retrospective application permitted. TEC is currently evaluating the impact of adoption of the standard on its financial statement disclosures.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting–Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses. The standard update improves the disclosures about a public business entity’s expenses by requiring more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation and amortization) included within income statement expense captions. The guidance will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The standard will be applied on a prospective basis, with retrospective application permitted. TEC is currently evaluating the impact of adoption of the standard on its financial statement disclosures.

3. Regulatory

Tampa Electric’s retail business and PGS are regulated by the FPSC. Tampa Electric is also subject to regulation by the FERC in various respects, including wholesale power sales, certain wholesale power purchases, transmission and ancillary services and accounting practices. The FPSC sets rates based on a cost of service methodology which allows utilities to collect total revenues (revenue requirements) equal to their prudently incurred cost of providing service or products, plus a reasonable return on equity invested or assets. As a result, Tampa Electric and PGS qualify for the application of accounting guidance for certain types of regulation. This guidance recognizes that the actions of a regulator can provide reasonable assurance of the existence of an asset or

45

liability. Regulatory assets and liabilities arise as a result of a difference between U.S. GAAP and the accounting principles imposed by the regulatory authorities. Regulatory assets generally represent incurred costs that have been deferred, as their future recovery in customer rates is probable. Regulatory liabilities generally represent obligations to make refunds to customers from previous collections for costs that are not likely to be incurred. In addition to regulatory assets and regulatory liabilities, rate regulation impacts other financial statement balances and activity, including, but not limited to, property, plant, and equipment, revenues, and expenses.

Tampa Electric Base Rates

Tampa Electric’s 2024, 2023 and 2022 base rates reflect a settlement agreement dated as of August 6, 2021 (the Settlement Agreement) by and among Tampa Electric and the intervenors in Tampa Electric’s 2021 rate case, which was approved by an FPSC order on November 10, 2021. The Settlement Agreement agreed to an increase in base rates annually effective with January 2022 bills, to generate a $191 million increase in revenue consisting of $123 million of traditional base rate charges and $68 million in a new charge to recover the costs of retiring assets. The Settlement Agreement further included two subsequent year adjustments of $90 million and $21 million, effective January 2023 and January 2024, respectively. Under the agreement, the allowed equity in the capital structure continued to be 54% from investor sources of capital. The Settlement Agreement included an allowed regulatory ROE range of 9.0% to 11.0% with a 9.95% midpoint. Under the agreement, base rates will not change from January 1, 2022 through December 31, 2024, unless Tampa Electric’s earned ROE were to fall below the bottom of the range during that time. The Settlement Agreement contained a provision whereby Tampa Electric agrees to quantify the future impact of a decrease or increase in corporate income tax rates on net operating income through a reduction or increase in base revenues within 180 days of when such tax change becomes law or its effective date. The Settlement Agreement further created a mechanism to recover the costs of retiring coal generation units and meter assets over a period of 15 years which survives the term of that agreement. The Settlement Agreement set new depreciation and dismantlement rates effective January 1, 2022 and contained the provisions that Tampa Electric will not have to file another depreciation study during the term of the agreement but will file a new depreciation study no more than one year, nor less than 90 days, before the filing of its next general base rate proceeding. Additionally, Tampa Electric agreed to a financial hedging moratorium for natural gas ending on December 31, 2024.

The Settlement Agreement allows a 25 basis point increase in the allowed ROE range and mid-point, and $10 million of additional revenue, if the average 30-year United States Treasury Bond yield rate for any period of six consecutive months is at least 50 basis points greater than the yield rate on the date the FPSC votes to approve the agreement. On July 1, 2022, Tampa Electric requested to adjust its base rates to collect an additional $10 million annually (prorated in the first year) effective September 1, 2022 and increase its mid-point ROE and upper and lower allowed ranges. On August 16, 2022, the FPSC approved the change. The new mid-point ROE is 10.20%, and the range is 9.25% to 11.25% effective July 1, 2022.

On April 2, 2024, Tampa Electric requested a base rate increase, reflecting an increased revenue requirement of $297 million, effective January 1, 2025, and additional adjustments of $100 million and $72 million for 2026 and 2027, respectively. Tampa Electric’s proposed rates include recovery of solar generation projects, energy storage capacity, a more resilient and modernized energy control center, and other resiliency and reliability projects. Prior to the rate case hearing, Tampa Electric submitted revisions to its requested base rate increase to reflect items that included production tax credits, energy storage life expectancy, and the company’s grid reliability and resilience project. The company’s August 22, 2024 requested revenue requirement reflects a base rate increase of $288 million, effective January 1, 2025, and adjustments of $92 million and $65 million for 2026 and 2027, respectively. From August 26 through 30, 2024, Tampa Electric’s rate case hearing was heard by the FPSC. On December 3, 2024, the FPSC rendered a decision during a Special Agenda and the final order, reflecting such decision, was issued on February 3, 2025. The FPSC decision includes an increase of $185 million in 2025 and adjustments of $87 million and $9 million in 2026 and 2027, respectively. The decision also allowed for equity in the capital structure to continue to be 54% from investor sources of capital. The allowed regulatory ROE range is 9.50% to 11.50% with a 10.50% midpoint, effective January 1, 2025. On February 18, 2025, a motion for reconsideration on certain aspects of the rate case order was filed with the FPSC. Tampa Electric will respond to this motion in February 2025. Tampa Electric expects the FPSC to reach a final decision on the motion in the second quarter of 2025.

Tampa Electric Storm Restoration Cost Recovery

In accordance with Tampa Electric’s 2021 rate case settlement agreement and continued with Tampa Electric's 2024 rate case order, in the event of a named storm that results in damage to its system, Tampa Electric can petition the FPSC to seek recovery of those costs over a 12-month period or longer as determined by the FPSC, as well as replenish its storm reserve regulatory liability of $56 million. Based on an FPSC order, if the charges to the storm reserve exceed the reserve liability account balance, the excess is to be carried as a regulatory asset. At December 31, 2024, the balance in the regulatory asset for storm restoration costs was $377 million.

In September 2022, Tampa Electric was impacted by Hurricane Ian. Total storm restoration costs were $129 million, with $121 million charged to the storm reserve. Restoration costs charged to the storm reserve exceeded the storm reserve balance and this amount was deferred to be collected from customers in subsequent periods. In November 2022, Tampa Electric incurred costs of approximately $2 million related to Hurricane Nicole. In January 2023, Tampa Electric petitioned the FPSC for recovery of costs associated with Hurricanes Ian and Nicole that exceeded the reserve, $10 million of storm restoration costs charged to the reserve

46

since 2018, and the replenishment of the balance in the reserve to the $56 million level that existed as of October 31, 2013 for a total of approximately $131 million. The storm cost recovery surcharge was approved by the FPSC on March 7, 2023, and Tampa Electric began applying the surcharge on April 2023 bills. Subsequently, on November 9, 2023, the FPSC approved Tampa Electric’s petition filed on August 16, 2023 to update the total storm cost collection from $129 million to approximately $134 million and change the collection of the expected remaining balance of approximately $29 million as of December 31, 2023, from over the first three months of 2024 to over the 12 months of 2024. On June 13, 2024, the FPSC issued an Order approving a total storm cost collection of $135 million.

In September 2023, Tampa Electric was impacted by Hurricane Idalia. The related storm restoration costs were approximately $35 million, which were charged to the storm reserve regulatory asset and not included in the petition above.

Hurricane Helene made landfall on September 26, 2024. Tampa Electric was impacted by Hurricane Helene, resulting in a peak number of customers out of approximately 100,000. As of December 31, 2024, TEC deferred $49 million to the storm reserve for future recovery, with a minimal impact to earnings.

​Hurricane Milton, the worst weather event to impact the area in over 100 years, made landfall on October 9, 2024. Tampa Electric was impacted by Hurricane Milton, resulting in a peak number of customers out of approximately 600,000. As of December 31, 2024, TEC deferred $340 million to the storm reserve for future recovery, with a minimal impact to earnings.

Restoration costs for the storms described above are deferred and will be collected from customers in subsequent periods. On February 4, 2025, the FPSC approved Tampa Electric’s petition filed on December 27, 2024 for the recovery of $466 million for costs associated with Hurricane Idalia, Hurricane Debby, Hurricane Helene and Hurricane Milton and the associated interest to replenish the storm reserve over an 18-month recovery period beginning in March 2025. The amount of cost-recovery is subject to a true-up mechanism with the FPSC.

Tampa Electric Big Bend Modernization Project

Tampa Electric invested $876 million, including $91 million of AFUDC, during 2018 through 2022 to modernize the Big Bend Power Station. The Big Bend modernization project repowered Big Bend Unit 1 with natural gas combined-cycle technology and eliminated coal as this unit’s fuel. As part of the Big Bend modernization project, Tampa Electric retired the Unit 1 components that will not be used in the modernized plant, Big Bend Unit 2 and Big Bend Unit 3 in 2020, 2021 and 2023, respectively.

Tampa Electric’s Settlement Agreement provided recovery for the Big Bend modernization project in two phases. The first phase was a revenue increase to cover the costs of the assets in service during 2022, among other items. The remainder of the project costs was recovered as part of the 2023 subsequent year adjustment. The Settlement Agreement also included a new charge to recover the remaining costs of the retiring Big Bend coal generation assets, Units 1 through 3, which will be spread over 15 years and will survive the term of the Settlement Agreement. The special capital recovery schedule for all three units was applied beginning January 1, 2022.

Tampa Electric Mid-Course Adjustment to Fuel Recovery

In January 2022, Tampa Electric requested a mid-course adjustment to its fuel and capacity charges to recover $169 million beginning April 1, 2022 through December 2022 due to an increase in fuel commodity and capacity costs. On March 1, 2022, the FPSC voted to approve the mid-course adjustment, and the order reflecting such approval was issued on March 18, 2022.

On January 23, 2023, Tampa Electric requested an adjustment to its fuel charges to recover the $518 million final 2022 fuel under-recovery over a period of 21 months. The request also included an adjustment to 2023 projected fuel costs to reflect the reduction in natural gas prices since September 2022 for a projected reduction of $170 million for the balance of 2023. The changes were approved by the FPSC on March 7, 2023, effective April 1, 2023.

On April 2, 2024, Tampa Electric requested a mid-course adjustment to its fuel and capacity charges, reflecting a $138 million reduction over 12 months, from June 2024 through May 2025. The requested reduction is due to a significant decrease in actual and projected 2024 natural gas prices since Tampa Electric submitted its projected 2024 costs in the fall of 2023. On May 7, 2024, the FPSC approved the mid-course adjustment.

Tampa Electric Storm Protection Cost Recovery Clause and Settlement Agreement

On October 3, 2019, the FPSC issued a rule to implement a Storm Protection Plan (SPP) Cost Recovery Clause. This clause provides a process for Florida investor-owned utilities, including Tampa Electric, to recover transmission and distribution storm hardening costs for incremental activities not already included in base rates. A settlement agreement was approved on August 10, 2020 and Tampa Electric’s cost recovery began in January 2021. The current approved plan addresses the years 2023, 2024 and 2025 and was approved by the FPSC on October 4, 2022.

PGS Base Rates

PGS’s results for 2022 reflected a rate case settlement agreement filed by PGS and the Office of Public Counsel and approved by the FPSC on November 19, 2020. The settlement agreement provides for an increase in base rates by $58 million annually effective January 2021, which is a $34 million increase in revenue and $24 million increase of revenues previously recovered through the cast iron and bare steel replacement rider. This settlement agreement includes an allowed regulatory ROE range of 8.90% to 11.00% with a 9.90% midpoint, including the ability to reverse a total of $34 million of accumulated depreciation through 2023. During 2023 and 2022, PGS reversed $20 million and $14 million, respectively, of accumulated depreciation.

Regulatory Assets and Liabilities

Details of the regulatory assets and liabilities are presented in the following table:

Total regulatory liabilities		904		795
Less: Current portion		146		94
Long-term regulatory liabilities	$	758	$	701

(1)The regulatory tax asset is primarily associated with the depreciation and recovery of AFUDC-equity. This asset does not earn a return but rather is included in the capital structure, which is used in the calculation of the weighted cost of capital used to determine revenue requirements. It will be recovered over the expected life of the related assets.

(2)These assets and liabilities are related to FPSC clauses and riders. They are recovered or refunded through cost-recovery mechanisms approved by the FPSC on a dollar-for-dollar basis in a subsequent period.

(3)This regulatory asset is related to the remaining net book value of Big Bend Units 1 through 3 and smart meter assets that were retired. The balance earns a rate of return as permitted by the FPSC and will be recovered as a separate line item on customer bills for a period of 15 years, beginning in 2022 through 2036. See “Tampa Electric Big Bend Modernization Project” above for further information.

(4)This regulatory asset is related to the remaining net book value of certain components of Polk Unit 1 that were early retired on December 31, 2024. The balance earns a rate of return as permitted by the FPSC and will be recovered through base rates over an 11-year recovery period beginning on January 1, 2025.

(5)This asset is related to the deferred costs of postretirement benefits and it is amortized over the remaining service life of plan participants. Deferred costs of postretirement benefits that are included in expense are recognized as cost of service for rate-making purposes as permitted by the FPSC.

(6)See "Tampa Electric Storm Restoration Cost Recovery" above for information regarding this reserve. The regulatory asset is included in rate base and earns a rate of return as permitted by the FPSC.

(7)The regulatory tax liability is primarily related to the revaluation of TEC’s deferred income tax balances recorded on December 31, 2017 at the lower corporate income tax rate due to U.S. tax reform. The liability related to the revaluation of the deferred

48

income tax balances is amortized and returned to customers through rate reductions or other revenue offsets based on IRS regulations and the settlement agreement for tax reform benefits approved by the FPSC.

(8)This item represents the non-ARO cost of removal in the accumulated reserve for depreciation. AROs are costs for legally required removal of property, plant and equipment. Non-ARO cost of removal represents estimated funds received from customers through depreciation rates to cover future non-legally required cost of removal of property, plant and equipment, net of salvage value upon retirement, which reduces rate base for ratemaking purposes. This liability is reduced as costs of removal are incurred.

(9) This regulatory liability represents the deferred benefit for production tax credits (PTC) available for qualifying solar facilities

placed in service on or after January 1, 2022, which reduced income tax expense. Following the recommendation of the FPSC, these PTC deferrals will be amortized over a three-year period.

4. Income Taxes

Inflation Reduction Act

On August 16, 2022, the Inflation Reduction Act was signed into legislation and includes numerous tax incentives for clean energy, such as the extension and modification of existing investment and production tax credits for projects placed in service through 2024, and new technology-neutral clean energy provisions related credits beginning in 2025. The Inflation Reduction Act also expanded the ITC for energy storage technology, including an election that permits these ITCs to be amortized over a period that is shorter than the life of the asset. During 2024, TEC placed in service its first standalone energy storage project eligible for the ITC and in accordance with the FPSC decision rendered on December 3, 2024, is amortizing this project over a five-year period.

TEC has determined that electing production tax credits for its solar plants placed in service through 2024 will be more beneficial for customers compared to ITCs and has recorded a regulatory liability in recognition of its obligation to pass the tax benefits to customers of $57 million and $23 million as of December 31, 2024 and 2023, respectively. In accordance with the FPSC decision rendered on December 3, 2024, the regulatory liability will be refunded to customers over a three-year period. See Note 3.

Income Tax Expense

TEC is included in a consolidated U.S. federal income tax return with EUSHI and its subsidiaries. TEC’s income tax expense is based upon a standalone return method, modified for the benefits-for-loss allocation in accordance with EUSHI's tax sharing agreement. To the extent that TEC’s cash tax positions are settled differently than the amount reported as realized under the tax sharing agreement, the difference is accounted for as either a capital contribution or a distribution.

Income tax expense consists of the following components:

Income Tax Expense (Benefit)

(millions)
For the year ended December 31,	2024			2023			2022
Current income taxes
Federal	$	2		$	84		$	(13	)
State		0			25			(3	)
Deferred income taxes
Federal		36			(19	)		105
State		34			5			38
Investment tax credits amortization		(4	)		(8	)		(6	)
Total income tax expense	$	68		$	87		$	121

49

During 2024 and 2022, TEC increased its net operating loss carryforward. Total current income tax expense for the years ending December 31, 2024 and December 31, 2022 were reduced by $13 million and $59 million, respectively, to reflect the benefits of operating loss carryforwards.

For the three years presented, the overall effective tax rate differs from the U.S. federal statutory rate as presented below:

Effective Income Tax Rate

(millions)
For the year ended December 31,	2024			2023			2022
Income before provision for income taxes	$	536		$	553		$	661
Federal statutory income tax rates		21	%		21	%		21	%

Total income tax expense on consolidated statements of income	$	68		$	87		$	121
Income tax expense as a percent of income before income taxes		12.7	%		15.7	%		18.3	%

Deferred Income Taxes

Deferred taxes result from temporary differences in the recognition of certain liabilities or assets for tax and financial reporting purposes. The principal components of TEC’s deferred tax assets and liabilities recognized in the balance sheet are as follows:

(millions)
As of December 31,	2024		2023
Deferred tax liabilities (1)
Property related	$	1,314	$	1,227
Deferred fuel		5		23
Pension and postretirement benefits		123		100
Storm reserve		95		2
Total deferred tax liabilities		1,537		1,352
Deferred tax assets (1)
Loss and credit carryforwards (2)		438		383
Medical benefits		22		19
Insurance reserves		2		3
Pension and postretirement benefits		62		49
Other		37		18
Total deferred tax assets		561		472
Total deferred tax liability, net	$	976	$	880

(1)Certain property related assets and liabilities have been netted.

(2)Deferred tax assets for net operating loss and tax credit carryforwards have been reduced by unrecognized tax benefits of $10 million and $10 million at December 31, 2024 and 2023, respectively.

The expiration of TEC's tax credits and net operating loss (NOL) carryforwards are as follows:

50

(millions)	December 31, 2024		Expiration Year
General business credits	$	361	2027-2044
Federal NOL carryforwards		135	2037
Federal NOL carryforwards (1)		248	indefinite
State NOL carryforwards (1)		359	indefinite
Total tax credits and NOL carryforwards	$	1,103

(1)Indefinite carryforward for Federal NOLs and NOLs for states that have adopted the U.S. Tax Cuts and Jobs Act of 2017 provisions, generated in tax years beginning after December 31, 2017.

TEC has unused general business credits of $361 million expiring between 2027 and 2044, of which $270 million relate to ITCs expiring between 2034 and 2044. As a result of TECO Energy's merger with Emera in 2016, TECs NOLs and credits will be utilized by EUSHI, in accordance with the benefits-for-loss allocation which provide that tax attributes are utilized by the consolidated tax return group of EUSHI.

Unrecognized Tax Benefits

TEC accounts for uncertain tax positions as required by U.S. GAAP. The following table provides details of the change in unrecognized tax benefits as follows:

(millions)	2024		2023		2022
Balance at January 1,	$	10	$	9	$	6
Increases due to tax positions related to prior year	0		0		2
Increases due to tax positions related to current year	0		1		1
Balance at December 31,	$	10	$	10	$	9

As of December 31, 2024 and 2023, TEC’s uncertain tax positions for federal research and development tax credits were $10 million and $10 million, respectively, all of which was recorded as a reduction of deferred income tax assets for tax credit carryforwards. The unrecognized tax benefits, if recognized, would reduce TEC’s effective tax rate.

TEC recognizes interest accruals related to uncertain tax positions in “Other income” or “Interest expense”, as applicable, and penalties in “Operation and maintenance expense” in the Consolidated Statements of Income. In 2024, 2023 and 2022, TEC did not recognize any pre-tax charges for interest or penalties.

The U.S. federal statute of limitations remains open for the year 2017 and forward. Florida’s statute of limitations is three years from the filing of an income tax return. The state impact of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. Years still open to examination by Florida’s tax authorities include 2013 and forward as a result of EUSHI’s consolidated Florida net operating loss still being utilized.

5. Employee Postretirement Benefits

Pension Benefits

TEC is a participant in the comprehensive retirement plans of TECO Energy, LLC (formerly known as TECO Energy, Inc. prior to April 1, 2024), including a qualified, non-contributory defined benefit retirement plan that covers substantially all employees. Subsequent to April 1, 2024, TECO Energy, LLC became a wholly owned subsidiary of the newly created TECO Holdings (see Note 1 for further detail.) Effective January 1, 2025, the comprehensive retirement plans were transferred to TECO Holdings. Benefits are based on the employees’ age, years of service and final average earnings. Where appropriate and reasonably determinable, the portion of expenses, income, gains or losses allocable to TEC are presented. Otherwise, such amounts presented reflect the amount allocable to all participants of the TECO Energy retirement plans.

Amounts disclosed for pension benefits in the following tables and discussion also include the fully-funded obligations for the SERP and the unfunded obligations of the Restoration Plan. The SERP is a non-qualified, non-contributory defined benefit retirement plan available to certain members of senior management. The Restoration Plan is a non-qualified, non-contributory defined benefit retirement plan that allows certain members of senior management to receive contributions as if no IRS limits were in place.

51

Other Postretirement Benefits

TECO Energy and its subsidiaries currently provide certain postretirement health care and life insurance benefits (other benefits) for most employees retiring after age 50 meeting certain service requirements. Where appropriate and reasonably determinable, the portion of expenses, income, gains or losses allocable to TEC are presented. Otherwise, such amounts presented reflect the amount allocable to all participants of the TECO Energy postretirement health care and life insurance plans. Postretirement benefit levels are substantially unrelated to salary. TECO Energy reserves the right to terminate or modify the plans in whole or in part at any time.

TECO Energy has made a change to the postretirement health plan to replace the pharmacy services provider. The change was treated as a plan amendment and the plan was remeasured as of September 30, 2023. See "Plan Amendments" line item in the "Obligations and Plan Assets" table below.

Obligations and Funded Status

TEC recognizes in its statement of financial position the over-funded or under-funded status of its allocated portion of TECO Energy’s postretirement benefit plans. This status is measured as the difference between the fair value of plan assets and the PBO in the case of its defined benefit plan, or the APBO in the case of its other postretirement benefit plan. Changes in the funded status are reflected, net of estimated tax benefits, in benefit liabilities and regulatory assets. The results of operations are not impacted.

The following table provides a detail of the change in TECO Energy’s benefit obligations and change in plan assets for combined pension plans (pension benefits) and TECO Energy’s Florida-based other postretirement benefit plan (other benefits).

TECO Energy	Pension Benefits						Other Benefits (2)

Fair value of plan assets at end of year (1)	$	686		$	686		$	0		$	0

(1)The market-related value of plan assets is used as the basis for calculating the expected return on plan assets component of periodic pension expense. The market-related value reflects the fair value of plan assets adjusted for experience gains and losses (i.e. the differences between actual investment returns and expected returns) spread over five years.

(2)Represent amounts for TECO Energy’s Florida-based other postretirement benefit plan.

(3)Represents TECO Energy’s SERP and Restoration settlement charges as a result of the retirement of certain executives. These charges did impact TEC’s financial statements.

Decreases in the benefit obligation for the period ended December 31, 2024 are the result of normal growth of the plan, due to the continued accrual of benefits, and increases in the discount rate used to calculate the benefit obligation.

52

At December 31, the aggregate financial position for TECO Energy pension plans and Florida-based other postretirement plans with projected benefit obligations and accumulated projected benefit obligations in excess of plan assets was as follows:

TECO Energy	Pension Benefits				Other Benefits (1)
Funded Status
(millions)	2024		2023		2024			2023
Benefit obligation (PBO/APBO)	$	674	$	678	$	130		$	132
Less: Fair value of plan assets		686		686		0			0
Funded status at end of year	$	12	$	8	$	(130	)	$	(132	)

(1)Represent amounts for TECO Energy’s Florida-based other postretirement benefit plan.

The accumulated benefit obligation for TECO Energy consolidated defined benefit pension plans was $638 million and $642 million at December 31, 2024 and 2023, respectively.

The amounts recognized in TEC’s Consolidated Balance Sheets for pension and other postretirement benefit obligations and plan assets at December 31 were as follows:

TEC	Pension Benefits						Other Benefits
Amounts recognized in balance sheet
(millions)	2024			2023			2024			2023

Assumptions used to determine benefit obligations at December 31:

	Pension Benefits						Other Benefits
	2024			2023			2024			2023
Discount rate		5.66	%		5.27	%		5.69	%		5.28	%

Ultimate rate	n/a			n/a				4.00	%		4.00	%
Year rate reaches ultimate trend rate	n/a			n/a			2050			2047

53

The discount rate assumption used to determine the December 31, 2024 and 2023 benefit obligation was based on a cash flow matching technique that matches yields from high-quality (AA-rated, non-callable) corporate bonds to TECO Energy’s projected cash flows for the plans to develop a present value that is converted to a discount rate assumption.

Amounts recognized in Net Periodic Benefit Cost, OCI and Regulatory Assets

(1)Represents amounts for TECO Energy’s Florida-based other postretirement benefit plan

(2)Represents TECO Energy’s SERP and Restoration settlement charges as a result of the retirement of certain executives. These charges did impact TEC’s financial statements.

TEC’s portion of the net periodic benefit costs for pension benefits was $0 million, $1 million and $8 million for 2024, 2023 and 2022, respectively. Tampa Electric’s portion of the net periodic benefit costs for pension benefits was $0 million, $1 million and $4 million for 2024, 2023 and 2022, respectively. TEC’s portion of the net periodic benefit costs for other benefits was $4 million, $5 million and $9 million for 2024, 2023 and 2022, respectively. Tampa Electric’s portion of the net periodic benefit costs for other benefits was $4 million, $5 million and $8 million for 2024, 2023 and 2022, respectively. Net periodic benefit costs for pension and other benefits is included as an expense on the Consolidated Statements of Income in “Operations & maintenance”.

Assumptions used to determine net periodic benefit cost for years ended December 31:

	Pension Benefits									Other Benefits
	2024			2023			2022			2024			2023			2022
Discount rate (1)		5.27	%	4.19%-5.55%				2.77	%		5.28	%	5.53%-6.14%				2.84	%
Expected long-term return on plan assets		7.05	%		7.05	%		6.50	%	n/a			n/a			n/a
Rate of compensation increase		4.42	%		3.79	%		3.05	%		4.42	%		3.79	%		3.04	%

Year rate reaches ultimate trend rate	n/a			n/a			n/a			2047			2047			2045

(1)Discount rate range is the result of remeasurements that occurred in 2023.

The discount rate assumption used to determine the benefit cost for 2024, 2023 and 2022 was based on the same technique that was used to determine the December 31, 2024 and 2023 benefit obligation as discussed above.

54

The expected return on assets assumption was based on historical returns, fixed income spreads and equity premiums consistent with the portfolio and asset allocation. A change in asset allocations could have a significant impact on the expected return on assets. Additionally, expectations of long-term inflation, real growth in the economy and a provision for active management and expenses paid were incorporated in the assumption. For the year ended December 31, 2024, TECO Energy’s pension plan’s actual return was approximately 5.1%.

The compensation increase assumption was based on the same underlying expectation of long-term inflation together with assumptions regarding real growth in wages and company-specific merit and promotion increases.

Pension Plan Assets

Pension plan assets are invested in a mix of equity and fixed-income securities. TECO Energy’s investment objective is to obtain above-average returns while minimizing volatility of expected returns and funding requirements over the long term. TECO Energy’s strategy is to hire proven managers and allocate assets to reflect a mix of investment styles, emphasize preservation of principal to minimize the impact of declining markets, and stay fully invested except for cash to meet benefit payment obligations and plan expenses.

TECO Energy	2024 Target Allocation			2023 Target Allocation			Actual Allocation, End of Year
Asset Category							2024			2023
Cash and cash equivalents	0%-10%			0%-10%				2	%		3	%
Equity securities	48%-68%			48%-68%				58	%		57	%
Fixed income securities	29%-49%			29%-49%				40	%		40	%
Total		100	%		100	%		100	%		100	%

TECO Energy reviews the plan’s asset allocation periodically and re-balances the investment mix to maximize asset returns, optimize the matching of investment yields with the plan’s expected benefit obligations, and minimize pension cost and funding. TECO Energy will continue to monitor the matching of plan assets with plan liabilities over the long term.

The plan’s investments are held by a trust fund administered by The Bank of New York Mellon. Investments are valued using quoted market prices on an exchange when available. Such investments are classified Level 1. In some cases where a market exchange price is available but the investments are traded in a secondary market, acceptable practical expedients are used to calculate fair value.

If observable transactions and other market data are not available, fair value is based upon third-party developed models that use, when available, current market-based or independently-sourced market parameters such as interest rates, currency rates or option volatilities. Items valued using third-party generated models are classified according to the lowest level input or value driver that is most significant to the valuation. Thus, an item may be classified in Level 3 even though there may be significant inputs that are readily observable.

As required by the fair value accounting standards, the investments are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The plan’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. For cash equivalents, the cost approach was used in determining fair value. For bonds and U.S. government agencies, the income approach was used. For other investments, the market approach was used. The following table sets forth by level within the fair value hierarchy the plan’s investments.

55

(1)In accordance with accounting standards, certain investments that are measured at fair value using the net asset value per share practical expedient have not been classified in the fair value hierarchy. The fair value amounts in this table are to permit reconciliation of the fair value hierarchy to amounts presented in the TECO Energy fair value of plan assets.

The following list details the pricing inputs and methodologies used to value the investments in the pension plan:

•Cash collateral is valued at cash posted due to its short-term nature.

•The STIF is valued at net asset value (NAV). The fund is an open-end investment, resulting in a readily-determinable fair value. Additionally, shares may be redeemed any business day at the NAV calculated after the order is accepted. The NAV is validated with purchases and sales at NAV. These factors make the STIF a level 1 asset.

•The primary pricing inputs in determining the fair value of the Common stocks, US Equity and REITs are closing quoted prices in active markets.

56

•The primary pricing inputs in determining the level 1 mutual funds are the mutual funds’ NAVs. The funds are registered open-end mutual funds and the NAVs are validated with purchases and sales at NAV. Since the fair values are determined and published, they are considered readily-determinable fair values and therefore level 1 assets.

•The primary pricing inputs in determining the fair value of municipal bonds are benchmark yields, historical spreads, sector curves, rating updates, and prepayment schedules. The primary pricing inputs in determining the fair value of government bonds are the U.S. treasury curve, consumer price index, and broker quotes, if available. The primary pricing inputs in determining the fair value of corporate bonds are the U.S. treasury curve, base spreads, YTM, and benchmark quotes. Collateralized mortgage obligations are priced using to-be-announced (TBA) prices, treasury curves, swap curves, cash flow information, and bids and offers as inputs. Mortgage-backed securities are priced using TBA prices, treasury curves, average lives, spreads, and cash flow information.

•The limited partnership pooled fund investment and common collective trusts are private funds valued at NAV. The NAVs are calculated based on bid prices of the underlying securities. Since the prices are not published to external sources, NAV is used as a practical expedient. Certain funds invest primarily in equity securities of domestic and foreign issuers while others invest in long duration U.S. investment-grade fixed income assets and seeks to increase return through active management of interest rate and credit risks. The redemption frequency of the funds ranges from daily to weekly and the redemption notice period ranges from 1 business day to 30 business days. There were no unfunded commitments as of December 31, 2024.

•Treasury bills are valued using benchmark yields, reported trades, broker dealer quotes, and benchmark securities.

•Futures are valued using futures data, cash rate data, swap rates, and cash flow analyses.

Additionally, the non-qualified SERP had $4 million and $4 million of assets as of December 31, 2024 and 2023, respectively. Since the plan is non-qualified, its assets are included in the “Deferred charges and other assets” line item in the Consolidated Balance Sheets rather than being netted with the related liability. The non-qualified trust holds investments in a money market fund. The fund is an open-end investment, resulting in a readily-determinable fair value. Additionally, shares may be redeemed any business day at the NAV calculated after the order is accepted. The NAV is validated with purchases and sales at NAV. These factors make it a level 1 asset. The SERP was fully funded as of December 31, 2024 and 2023.

Other Postretirement Benefit Plan Assets

There are no assets associated with TECO Energy’s Florida-based other postretirement benefits plan.

Contributions

The qualified pension plan’s actuarial value of assets, including credit balance, was 110.22% of the Pension Protection Act funded target as of January 1, 2024 and is estimated at 100.38% of the Pension Protection Act funded target as of January 1, 2025.

TECO Energy’s policy is to fund the qualified pension plan at or above amounts determined by its actuaries to meet ERISA guidelines for minimum annual contributions. TEC’s contribution is first set equal to its service cost. If a contribution in excess of service cost for the year is made, TEC’s portion is based on TEC’s proportion of the TECO Energy unfunded liability. TECO Holdings made contributions to this plan in 2024 and TECO Energy made contributions to this plan in 2024, 2023 and 2022, which met the minimum funding requirements for 2024, 2023 and 2022. TEC’s portion of the contribution in 2024 was $10 million, in 2023 was $10 million and in 2022 was $15 million. Tampa Electric’s portion of the contribution was $10 million in 2024, $10 million in 2023 and $12 million 2022. These amounts are reflected in the “Other” line on the Consolidated Statements of Cash Flows. TEC estimates its portion of the 2025 contribution to be $11 million. The amount TECO Holdings expects to contribute is in excess of the minimum funding required under ERISA guidelines.

TEC’s portion of the contributions to the SERP in 2024, 2023 and 2022 was zero. Since the SERP is fully funded, TECO Holdings does not expect to make significant contributions to this plan in 2025. TEC made SERP payments of approximately $0 million, $5 million and $2 million from the trust in 2024, 2023 and 2022, respectively.

The other postretirement benefits are funded annually to meet benefit obligations. TECO Energy's contribution toward health care coverage for most employees who retired after the age of 55 between January 1, 1990 and June 30, 2001 is limited to a defined dollar benefit based on service. TECO Energy’s contribution toward pre-65 and post-65 health care coverage for most employees retiring on or after July 1, 2001 is limited to a defined dollar benefit based on an age and service schedule. In 2025, TEC expects to make a contribution of approximately $10 million. Postretirement benefit levels are substantially unrelated to salary.

57

Benefit Payments

The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid:

Defined Contribution Plan

TECO Energy has a defined contribution savings plan covering substantially all employees of TECO Energy and its subsidiaries that enables participants to save a portion of their compensation up to the limits allowed by IRS guidelines. TECO Energy and its subsidiaries match 75% of the first 6% of the participant’s payroll savings deductions. Effective January 1, 2017, the employer matching contributions increased from 70% to 75% with an additional incentive match of up to 25% of eligible participant contributions based on the achievement of certain operating company financial goals. For the years ended December 31, 2024, 2023 and 2022, TEC’s portion of expense totaled $20 million, $18 million and $22 million, respectively, related to the matching contributions made to this plan. Tampa Electric’s portion of expense totaled $20 million, $18 million and $19 million, respectively, related to the matching contributions made to this plan. The expense related to the matching contribution is included on the Consolidated Statements of Income in “Operations & maintenance”.

Effective October 21, 2019, TECO Energy amended the defined contribution plan such that certain participants covered by the IBEW collective bargaining agreement shall not be eligible to participate in the plan for purposes of receiving the fixed matching contribution. This has been replaced with a non-elective employer contribution on a bi-weekly basis equal to a percentage of the member’s compensation for that period based on years of tenure of employment. For the years ended December 31, 2024, 2023 and 2022, Tampa Electric recognized expense totaling $11 million, $10 million and $10 million, respectively, related to the contributions made to this plan. The expense related to this contribution is included on the Consolidated Statements of Income in “Operations & maintenance”.

(1)Borrowings outstanding are reported as notes payable in the Consolidated Balance Sheets.

(2)On April 1, 2024, TEC amended the credit facility agreement to extend the maturity date to December 1, 2028. TEC also has an active commercial paper program for up to $800 million, of which the full amount outstanding is backed by TEC’s credit facility. The amount of commercial paper issued results in an equal amount of its credit facility being considered drawn and unavailable. On January 30, 2024, TEC completed a sale of $500 million aggregate principal amount of 4.90% Notes due March 1, 2029. TEC used the net proceeds from this offering for the repayment of a portion of the borrowings outstanding under the 5-year credit facility. Therefore, $497 million of borrowings outstanding under the 5-year credit facility were reclassified as long-term debt on the Consolidated Balance Sheet as of December 31, 2023.

(3)On March 1, 2023, TEC entered into a 1-year term facility that matured on February 28, 2024.

(4)On April 3, 2023, TEC entered into a 1-year term facility that matured on April 1, 2024.

58

At December 31, 2024, the credit facility required a commitment fee of 12.5 basis points. The weighted-average interest rate on borrowings outstanding under the credit facilities and commercial paper at December 31, 2024 and 2023 was 4.8% and 5.7%, respectively.

On January 1, 2023, TEC transferred the assets and liabilities of its PGS division into a separate corporation called PGSI pursuant to a Contribution Agreement. Prior to the separation, as a division of TEC, PGS had received an allocation of outstanding unsecured notes and outstanding short-term borrowings issued by TEC. The obligations related to these combined borrowings were reflected in an affiliate loan agreement between Tampa Electric and PGS. The initial obligation of PGS under the loan agreement at January 1, 2023 was a term loan in the principal amount of $670 million and a revolving loan in the principal amount of $66 million. The maturity date for both was December 29, 2023. On December 20, 2023, PGS repaid Tampa Electric the outstanding principal amount of the term loan and revolving loan of $670 million and $286 million, respectively, plus outstanding interest. The repayment terminates the affiliate loan agreement and Tampa Electric will no longer provide capital for the operations of PGS.

In December 2023, Tampa Electric used the proceeds of the PGS repayment in part to repay $400 million in credit facility borrowings, the $195 million note payable to TECO Energy and $149 million of the commercial paper borrowed under the 5-year term facility.

Commercial Paper Program

On May 25, 2021, TEC established a commercial paper program (the Program) under which TEC may issue on a private placement basis unsecured commercial paper notes (the Notes). Amounts available under the Program may be borrowed, repaid and reborrowed with the aggregate amount of the Notes outstanding under the Program at any time not to exceed $800 million. The maturities of the Notes will vary, but may not exceed 270 days from the date of issue. The rates of interest will depend on whether the Note will be a fixed or floating rate. TEC must have credit facilities in place, at least equal to the amount of its commercial paper program. TEC cannot issue commercial paper in an aggregate amount exceeding the then available capacity under its credit facility.

5-Year Credit Facility

On December 17, 2021, TEC amended and restated its $800 million bank credit facility, entering into a Seventh Amended and Restated Credit Agreement. The amendment extended the maturity date of the credit facility from March 22, 2023 to December 17, 2026 (subject to further extension with the consent of each lender); and provided for an interest rate based on either the London interbank deposit rate, Wells Fargo Bank’s prime rate, or the federal funds rate, plus a margin; allows TEC to borrow funds on a same-day basis under a swingline loan provision, which loans mature on the fourth banking day after which any such loans are made and bear interest at an interest rate as agreed by the borrower and the relevant swingline lender prior to the making of any such loans; continues to allow TEC to request the lenders to increase their commitments under the credit facility by up to $100 million in the aggregate; and made other technical changes. On April 3, 2023, TEC amended the agreement to replace the London interbank deposit rate with the SOFR. On April 1, 2024, TEC amended the credit facility agreement to extend the maturity date to December 1, 2028.

7. Long-Term Debt

A substantial part of Tampa Electric’s tangible assets are pledged as collateral to secure its first mortgage bonds. There are currently no bonds outstanding under Tampa Electric’s first mortgage bond indenture, and Tampa Electric could cause the lien associated with this indenture to be released at any time.

TEC 4.90% Notes due 2029

On January 30, 2024, TEC completed a sale of $500 million aggregate principal amount of 4.90% Notes due March 1, 2029 (the 2029 Notes). Prior to February 1, 2029, in the case of the 2029 Notes, TEC may redeem all or any part of such series of Notes at its option at a redemption price equal to the greater of (i) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date on a semi-annual basis at the Treasury Rate plus 15 basis points less interest accrued to the date of redemption or (ii) 100% of the principal amount of the notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the redemption date. On or after February 1, 2029, TEC may redeem the 2029 Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to the redemption date. TEC used the net proceeds from this offering for the repayment of a portion of the borrowings outstanding under the 5-year credit facility. Therefore, $497 million of borrowings outstanding under the 5-year credit facility were reclassified from notes payable to long-term debt on the Consolidated Balance Sheet as of December 31, 2023.

TEC 3.875% Notes due 2024 and 5.00% Notes due 2052

On July 12, 2022, TEC completed a sale of (i) $300 million aggregate principal amount of 3.875% Notes due July 12, 2024 (the 2024 Notes) and (ii) $300 million aggregate principal amount of 5.00% Notes due July 15, 2052 (the 2052 Notes, and collectively, the Notes). Until July 12, 2024, in the case of the 2024 Notes, or January 15, 2052, in the case of the 2052 Notes, TEC may redeem all or any part of such series of Notes at its option at a redemption price equal to the greater of (i) 100% of the principal amount of such series of Notes to be redeemed or (ii) the sum of the present values of the remaining payments of principal and interest on the Notes to be redeemed that would be due if the Notes matured on (a) July 12, 2024, in the case of the 2024 Notes, discounted to the redemption date on a semiannual basis at the applicable treasury rate (as defined in the Indenture), plus 15 basis points, or (b) July 15, 2052, in the case of the 2052 Notes, discounted to the redemption date on a semiannual basis at the applicable treasury rate, plus 30 basis points; in either case, the redemption price would include accrued and unpaid interest to the redemption date. At any time on or after January 15, 2052, in the case of the 2052 Notes, TEC may, at its option, redeem the 2052 Notes, in whole or in part, at 100% of the principal amount of such series of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the date of redemption. On July 12, 2024, TEC repaid the $300 million 2024 Notes upon maturity. This note was repaid with proceeds from commercial paper.

8. Commitments and Contingencies

Legal Contingencies

From time to time, TEC and its subsidiaries are involved in various legal, tax and regulatory proceedings before various courts, regulatory commissions and governmental agencies in the ordinary course of business. Where appropriate, accruals are made in accordance with accounting standards for contingencies to provide for matters that are probable of resulting in an estimable loss.

Superfund and Former Manufactured Gas Plant Sites

As of December 31, 2024, TEC, through its Tampa Electric division and former PGS division, was a PRP for certain superfund sites and, through its former PGS division, for certain former MGP sites. As a result of the separation of the PGS division, PGS is now the responsible party for those sites (in addition to third party PRPs for certain sites). See Note 1 to the 2024 Annual TEC Consolidated Financial Statements for information regarding the separation of PGS from TEC.

Long-Term Commitments

TEC has commitments for various purchases as disclosed below, including payment obligations for capital projects and contractual agreements for fuel, fuel transportation and power purchases that are recovered from customers under regulatory clauses. The following is a schedule of future payments under net purchase obligations/commitments at December 31, 2024:

11. Segment Information

Segments are determined based on how TEC's chief operating decision maker (CODM) evaluates, measures and makes decisions with respect to the operations of the entity, resulting in segments based on products and services (i.e., electric and gas). Management reports segments based on each segment’s contribution of revenues, net income and total assets as required by the accounting guidance for disclosures about segments of an enterprise and related information. All significant intercompany transactions are eliminated in the Consolidated Financial Statements of TEC but are included in determining operating segments.

TEC is a public utility operating within the State of Florida. Prior to January 1, 2023, TEC’s segments were comprised of Tampa Electric, the electric division, and PGS, the natural gas division of TEC. Due to the separation of PGS from TEC, TEC operates under a single operating and reportable segment effective January 1, 2023 because the operations of TEC only include the operations of the electric division. See "Separation of PGS from TEC" in Note 1 for further information regarding the separation of PGS from TEC. Through its Tampa Electric division, it is engaged in the generation, purchase, transmission, distribution and sale of electric energy to approximately 855,000 customers in West Central Florida.

TEC's CODM is the Chief Executive Officer. The CODM uses several measures to allocate capital and resources for TEC, predominantly in the annual budget and forecasting processes. The CODM evaluates performance by considering budget-to-actual variances for these measures monthly. The measure used by the CODM that is the most consistent with US GAAP measurement principles is net income.

12. Asset Retirement Obligations

Tampa Electric accounts for AROs at fair value at inception of the obligation if there is a legal obligation under applicable law, a written or oral contract, or by legal construction under the doctrine of promissory estoppel. Retirement obligations are recognized only if the legal obligation exists in connection with or as a result of the permanent retirement, abandonment or sale of a long-lived asset. When the liability is initially recorded in “Deferred credits and other liabilities” in the Consolidated Balance Sheets, the carrying amount of the related long-lived asset is correspondingly increased. Over time, the liability is accreted to its estimated future value. The corresponding amount capitalized at inception is depreciated over the remaining useful life of the asset. The ARO estimates are reviewed quarterly. Any updates are revalued based on current market prices.

Reconciliation of beginning and ending carrying amount of asset retirement obligations:

Beginning balance	$	32	$	35
Additional liabilities		8		1
Liabilities settled		0		(4	)
Ending balance	$	40	$	32

13. Leases

TEC determines whether a contract contains a lease at inception by evaluating if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

Operating lease ROU assets and operating lease liabilities are recognized on the Consolidated Balance Sheets based on the present value of the future minimum lease payments over the lease term at commencement date. As most of TEC’s leases do not provide an implicit rate, the incremental borrowing rate at commencement of the lease is used in determining the present value of future lease payments. Lease expense is recognized on a straight-line basis over the lease term and is recorded as “Operations and maintenance expenses” on the Consolidated Statements of Income.

TEC has certain contractual agreements that include lease and non-lease components, which management has elected to account for as a single lease component for all leases in which TEC is the lessee.

Lessee

Tampa Electric has operating leases for buildings, land, telecommunication services and rail cars. Tampa Electric’s leases have remaining lease terms of 1 year to 61 years, some of which include options to extend the leases for up to an additional 65 years. These options are included as part of the lease term when it is considered reasonably certain that they will be exercised.

Tampa Electric has recorded operating lease expense for the year ended December 31, 2024, 2023 and 2022 of $5 million, $4 million and $4 million, respectively.

Future minimum lease payments under non-cancellable operating leases for each of the next five years and in aggregate thereafter consisted of the following at December 31, 2024:

14. Fair Value Measurements

Items Measured at Fair Value on a Recurring Basis

Accounting guidance governing fair value measurements and disclosures provides that fair value represents the amount that would be received in selling an asset or the amount that would be paid in transferring a liability in an orderly transaction between market participants. As a basis for considering assumptions that market participants would use in pricing an asset or liability, accounting guidance also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1:	Observable inputs, such as quoted prices in active markets;
Level 2:	Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
Level 3:	Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.

There were no Level 3 assets or liabilities for the periods presented.

As of December 31, 2024 and 2023, the fair value of TEC’s short-term debt was not materially different from the carrying value due to the short-term nature of the instruments and because the stated rates approximate market rates. The fair value of TEC’s short-term debt is determined using Level 2 measurements.

See Note 5 and Consolidated Statements of Capitalization for information regarding the fair value of the pension plan investments and long-term debt, respectively.

15. Long-Term PPAs

In 2019, Tampa Electric entered into a long-term PPA with a wholesale energy provider in Florida with up to 515 MW of available capacity, which expires in 2025. Because some of these provisions provide for the transfer or sharing of a number of risks inherent in the generation of energy, these agreements meet the definition of being variable interests. These risks include: operating and maintenance, regulatory, credit, commodity/fuel and energy market risk. Tampa Electric reviewed these risks and determined that the owners of these entities retain the majority of these risks over the expected life of the underlying generating assets, have the power to direct the most significant activities, and have the obligation or right to absorb losses or benefits. As a result, Tampa Electric was not the primary beneficiary and was not required to consolidate any of these entities. Tampa Electric purchased $34 million, $35 million and $70 million under this long-term PPA for the three years ended December 31, 2024, 2023 and 2022, respectively.

TEC does not provide any material financial or other support to any of the variable interests it is involved with, nor is TEC under any obligation to absorb losses associated with these variable interests. Excluding the payments for energy under these contracts, TEC’s involvement with these variable interests does not affect its Consolidated Balance Sheets, Statements of Income or Cash Flows.

Item 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

Item 9A. CONTROLS AND PROCEDURES

Conclusions Regarding Effectiveness of Disclosure Controls and Procedures.

TEC’s management, with the participation of its principal executive officer and principal financial officer, has evaluated the effectiveness of TEC’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act)) as of the end of the period covered by this annual report, December 31, 2024 (Evaluation Date). Based on such evaluation, TEC’s principal executive officer and principal financial officer have concluded that, as of the Evaluation Date, TEC’s disclosure controls and procedures are effective.

Management’s Report on Internal Control over Financial Reporting.

TEC’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Securities Exchange Act of 1934, as amended. We conducted an evaluation of the effectiveness of TEC’s internal control over financial reporting as of December 31, 2024 based on the 2013 framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under this framework, our management concluded that TEC’s internal control over financial reporting was effective as of December 31, 2024.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. A control system, no matter how well designed and operated, can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control over Financial Reporting.

There was no change in TEC’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) identified in connection with the evaluation of TEC’s internal controls that occurred during TEC’s last fiscal quarter that has materially affected, or is reasonably likely to materially affect, such controls.
