TAMPA ELECTRIC COMPANY

NOTES TO CONDENSED FINANCIAL STATEMENTS

UNAUDITED

1. Summary of Significant Accounting Policies

See TEC’s Annual Report on Form 10-K for the year ended December 31, 2023 for a complete discussion of accounting policies. The significant accounting policies for TEC include:

Principles of Consolidation and Basis of Presentation

TEC is comprised of the electric division, referred to as Tampa Electric, and prior to January 1, 2023, the natural gas division, referred to as PGS. 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. This new corporation is also an indirect, wholly owned subsidiary of Emera.

In the opinion of management, the unaudited condensed financial statements include all adjustments that are of a recurring nature and necessary to state fairly the financial position of TEC as of March 31, 2024 and December 31, 2023, and the results of operations and cash flows for the periods ended March 31, 2024 and 2023. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results that can be expected for the entire fiscal year ending December 31, 2024.

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. The year-end Condensed Balance Sheet was derived from audited financial statements; however, this quarterly report on Form 10-Q does not include all year-end disclosures required for an annual report on Form 10-K by U.S. GAAP.

Receivables and Allowance for Credit Losses

Receivables on the Condensed Balance Sheets include receivables from contracts with customers, which consist of services to residential, commercial, industrial and other customers, totaling $243 million and $284 million as of March 31, 2024 and December 31, 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 could affect TEC’s estimates of credit losses include, but are not limited to, customer credit issues, generating fuel prices, customer deposits and general economic conditions. Accounts are reserved in the allowance or written off once they are deemed to be uncollectible.

As of March 31, 2024 and December 31, 2023, unbilled revenues of $67 million and $63 million, respectively, are included in the “Receivables” line item on the Condensed Balance Sheets.

Accounting for Franchise Fees and Gross Receipts

TEC is allowed to recover certain costs from customers on a dollar-for-dollar basis 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 Condensed Statements of Income. Franchise fees and gross receipt taxes payable by TEC are included as an expense on the Condensed Statements of Income in “Taxes, other than income”. These amounts totaled $26 million and $28 million for the three months ended March 31, 2024 and 2023, respectively.

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 will be effective for annual reporting periods beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. Early adoption is permitted. The standard will be applied retrospectively. TEC is currently evaluating the impact of adoption of the standard on its financial statement disclosures.

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 –

9

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. 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 Base Rates

On April 2, 2024, Tampa Electric requested a base rate increase, reflecting a revenue requirement increase 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 numerous other resiliency and reliability projects. A decision by the FPSC is expected by the end of 2024.

Tampa Electric Mid-Course Adjustment to Fuel Recovery

On April 2, 2024, Tampa Electric requested a mid-course adjustment to its fuel and capacity charges, reflecting a $137 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 voted to approve the mid-course adjustment.

Regulatory Assets and Liabilities

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

Regulatory Assets and Liabilities
(millions)	March 31, 2024		December 31, 2023
Regulatory assets:
Regulatory tax asset (1)	$	113	$	112
Cost-recovery clauses (2)		46		94
Capital cost recovery for early retired assets (3)		514		507
Postretirement benefits (4)		236		236
Storm reserve (5)		2		7
Other		30		32
Total regulatory assets		941		988
Less: Current portion		109		161
Long-term regulatory assets	$	832	$	827
Regulatory liabilities:
Regulatory tax liability (6)	$	474	$	477
Cost-recovery clauses - deferred balances (2)		14		20
Accumulated reserve - cost of removal (7)		300		271
Other		33		27
Total regulatory liabilities		821		795
Less: Current portion		91		94
Long-term regulatory liabilities	$	730	$	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, primarily related to the fuel clause and the decrease in natural gas prices. 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 asset is related to the remaining net book value of Big Bend Units 1 through 3 and 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.

10

(4)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.

(5)This asset is related to storm restoration cost recovery. The regulatory asset is included in rate base and earns interest as permitted by the FPSC.

(6)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 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.

(7)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.

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, the expansion of ITC for energy storage technology beginning in 2023 and introduces new technology-neutral clean energy related credits beginning in 2025. 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 $29 million and $23 million as of March 31, 2024 and December 31, 2023, respectively.

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 respective tax sharing agreements with TECO Energy and EUSHI. 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.

TEC’s effective tax rates for the three months ended March 31, 2024 and 2023 were 11.3% and 16.0%, respectively. The March 31, 2024 and 2023 effective tax rates are an estimate of the annual effective income tax rate. TEC’s effective tax rate for the three months ended March 31, 2024 and 2023 differed from the statutory rate principally due to production tax credits and amortization of the regulatory tax liability resulting from tax reform. The effective tax rate for the three months ended March 31, 2024 is lower compared to the same period in 2023 primarily due to production tax credits. See Note 3 for further information regarding the regulatory tax liability.

Unrecognized Tax Benefits

As of March 31, 2024 and December 31, 2023, the amount of unrecognized tax benefits was $10 million, 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.

11

5. Employee Postretirement Benefits

TEC is a participant in the comprehensive retirement plans of TECO Energy. The following table presents detail related to TECO Energy’s periodic benefit cost for pension and other postretirement benefits. Amounts disclosed for TECO Energy’s pension benefits include the amounts related to its qualified pension plan and non-qualified, non-contributory SERP and Restoration Plan.

TECO Energy Benefit Cost
(millions)	Pension Benefits						Other Postretirement Benefits
Three months ended March 31,	2024			2023			2024			2023
Components of net periodic benefit cost
Service cost	$	4		$	4		$	0		$	0
Interest cost		9			9			2			2
Expected return on assets		(14	)		(14	)		0			0
Amortization of actuarial loss (gain)		2			1			(1	)		0
Net periodic benefit cost	$	1		$	0		$	1		$	2

TEC’s portion of the net periodic benefit cost for the three months ended March 31, 2024 and 2023, respectively, was $0 million and $0 million for pension benefits, and $1 million and $1 million for other postretirement benefits. TEC’s portion of net periodic benefit costs for pension and other benefits is included as an expense on the Condensed Statements of Income in “Operations & maintenance”.

TECO Energy assumed a long-term EROA of 7.05% and a discount rate of 5.27% for pension benefits under its qualified pension plan for 2024. For TECO Energy’s other postretirement benefits, TECO Energy used a discount rate of 5.28% for 2024.

TECO Energy made contributions of $4 million and $4 million to its qualified pension plan in the three months ended March 31, 2024 and 2023, respectively. TEC’s portion of these contributions was $2 million and $3 million, respectively. TECO Energy expects to make contributions to the pension plan of $12 million for the remainder of 2024. TEC estimates its portion of the remaining 2024 contribution to be $8 million.

Included in the benefit cost discussed above, for the three months ended March 31, 2024, $1 million of unamortized prior service benefits and costs and actuarial gains and losses were reclassified by TEC from regulatory assets to the Condensed Statement of Income, compared with $0 million for the three months ended March 31, 2023, respectively.

6. Short-Term Debt

Details of TEC’s short-term borrowings are presented in the following table:

	March 31, 2024								December 31, 2023
			Borrowings		Borrowings		Letters				Borrowings		Borrowings		Letters
	Credit		Outstanding -		Outstanding -		of Credit		Credit		Outstanding -		Outstanding -		of Credit
(millions)	Facilities		Credit Facilities (1)		Commercial Paper (1)		Outstanding		Facilities		Credit Facilities (1)		Commercial Paper (1)		Outstanding
Credit facility (2)	$	800	$	0	$	56	$	1	$	800	$	0	$	706	$	1
1-year term facility (3)		0		0		0		0		200		0		0		0

Total	$	1,000	$	0	$	56	$	1	$	1,200	$	0	$	706	$	1

(1)Borrowings outstanding are reported as notes payable.

(2)This credit facility was planned to mature on December 17, 2026. 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 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 March 31, 2024, these credit facilities 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 March 31, 2024 and December 31, 2023 was 5.48% and 5.68%, respectively.

As of March 31, 2024 and December 31, 2023, the carrying value of TEC’s short-term debt was not materially different from the fair 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.

7. Long-Term Debt

Fair Value of Long-Term Debt

At March 31, 2024, TEC’s long-term debt, including the current portion, had a carrying amount of $4,233 million and an estimated fair market value of $3,746 million. At December 31, 2023, long-term debt had a carrying amount of $4,233 million and an estimated fair market value of $3,831 million. The fair value of the debt securities is determined using Level 2 measurements.

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 credit facility. Therefore, $497 million of borrowings outstanding under the credit facility were reclassified from notes payable to long-term debt on the Balance Sheet as of December 31, 2023.

Remaining Performance Obligations

Remaining performance obligations primarily represent lighting contracts with fixed contract terms. As of March 31, 2024 and December 31, 2023, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately

14

$78 million and $78 million, respectively. As allowed under ASC 606, Revenue from Contracts with Customers, these amounts exclude contracts with an original expected length of one year or less and variable amounts for which TEC recognizes revenue at the amount to which it has the right to invoice for services performed. TEC expects to recognize revenue for the remaining performance obligations through 2044.

Item 2. MANAGEMENT’S DISCUSSION & ANALYSIS OF FINANCIAL CONDITION & RESULTS OF OPERATIONS

Operating Company Results

Amounts included in the operating company discussions below are pre-tax, except net income and income taxes.

Tampa Electric’s net income for the first quarter of 2024 was $63 million, compared with $79 million for the same period in 2023. Results primarily reflected higher O&M expense, higher depreciation expense and lower base revenues. 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.

Revenues were $4 million lower than in the same period in 2023, primarily driven by the impact of less favorable weather of $13 million, 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 the first quarter of 2024 were 13% below normal (a 20-year statistical degree day average) and 17% below the 2023 period, reflecting mild weather in the first quarter of 2024 compared to 2023. As revenue also reflects a 2% increase in the number of customers in the first quarter of 2024 compared to the same period in 2023, net energy for load, which is a calendar measurement of energy output, decreased by only 3% in the first quarter of 2024 compared to the same period in 2023.

In 2024, operations and maintenance expense was $16 million higher than in 2023 due to increased operational expenses of $8 million, storm restoration cost recognition of $6 million related to storm surcharge revenue (offset in revenue), and increased expenses related to clauses and regulatory deferrals of $2 million. The increase in operating expenses was primarily due to higher generation maintenance, transmission and distribution expense, and bad debt expense. Depreciation and amortization expense increased $8 million in 2024 compared to 2023 as a result of additions to facilities and the in-service of generation projects.

Tampa Electric’s regulated operating statistics for the three months ended March 31, 2024 and 2023 were as follows:

(millions, except customers and total degree days)	Operating Revenues									Kilowatt-Hours Billed
Three months ended March 31,	2024			2023			% Change			2024		2023		% Change

Other Income

For the first quarter of 2024 and 2023, respectively, TEC’s other income was $11 million and $21 million, which included AFUDC-equity of $5 million and $3 million, interest income from affiliate of $0 and $8 million, and other income of $6 million and $10 million. The decrease in interest income from affiliate is primarily due to the repayment of the receivable from PGS on December 20, 2023. The decrease in Other Income is primarily due to lower interest income on the deferred fuel balance.

Interest Expense

For the first quarter of 2024 and 2023, TEC’s interest expense, including interest expense to affiliates and excluding AFUDC-debt, was $51 million and $59 million, respectively. The decrease 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. The weighted-average interest rate on borrowings outstanding under the credit facilities and commercial paper at March 31, 2024 and 2023 was 5.48% and 5.55%, respectively. See Other Income above for information regarding the 2023 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 2023 interest income from affiliate partially offsets the impact of TEC's 2023 interest expense within Net Income on the Statement of Income.

Income Taxes

The provisions for income taxes were $8 million and $15 million for the three months ended March 31, 2024 and 2023, respectively. Compared to the 2023 periods, the decrease in the provision for income taxes for the three months ended March 31, 2024 was primarily the result of lower pre-tax income and production tax credits related to solar facilities.

Liquidity and Capital Resources

The table below sets forth the March 31, 2024 liquidity, cash balances and amounts available under the TEC credit facilities.

(millions)
Credit facilities/ commercial paper / advances from affiliates	$	800
Drawn amounts/letters of credit		(57	)
Available credit facilities		743
Cash		6
Total liquidity	$	749

Cash Impacts Related to Operating Activities

Cash flows from operating activities in 2024 were $205 million, an increase of $54 million compared to 2023. Increases to cash from operations were primarily due to changes in accounts receivable balances resulting from decreased fuel and storm cost recoveries reflected in customer bills and the timing of vendor invoice payments.

Cash Impacts Related to Financing Activities

Cash flows from financing activities for the three months ended March 31, 2024 resulted in net cash inflows of $61 million. TEC received $496 million of net proceeds from a long-term debt issuance and $300 million of equity contributions from Parent, partially offset by $650 million of net payments in short-term debt with maturities with 90 days or less and $85 million of dividends to Parent.

Covenants in Financing Agreements

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 March 31, 2024, TEC was in compliance with all applicable financial covenants. The following table contains the significant financial covenant and the performance relative to it at March 31, 2024.

Commitments and Contingencies

See Note 8 to the TEC Condensed Financial Statements for information regarding TEC’s commitments and contingencies as of March 31, 2024.

Regulatory Matters

See Note 3 to the TEC Condensed Financial Statements for information regarding TEC’s regulatory matters as of March 31, 2024.

Fair Value Measurements

TEC considered the impact of nonperformance risk in determining the fair value of derivatives. TEC considered the net position with each counterparty, past performance and the intent of the parties, indications of credit deterioration and whether the markets in which TEC transacts have experienced dislocation. At March 31, 2024, the fair value of derivatives was not materially affected by nonperformance risk.

Critical Accounting Policies and Estimates

Critical accounting policies and estimates have not materially changed in 2024. For further discussion of critical accounting policies and estimates, see TEC’s Annual Report on Form 10-K for the year ended December 31, 2023.

Environmental Compliance

On April 24, 2024, the EPA issued its final power plant rules for electric generating units, including (i) new GHG standards; (ii) Mercury and Air Toxics Standards (MATS); (iii) Effluent Limit Guidelines (ELGs) and (iv) new Coal Combustion Residual (CCR) rules. The new MATS and ELGs 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.

The new CCR rule 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.

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

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Information required by Item 3 is omitted pursuant to General Instruction H(2) of Form 10-Q.

Item 4. CONTROLS AND PROCEDURES

(a)Evaluation 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

(b)Changes in Internal Controls. There was no change in TEC’s internal controls 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 control over financial reporting that occurred during TEC’s last fiscal quarter that has materially affected, or is reasonably likely to materially affect, such controls.
