style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP is a regulated utility that generates, transmits, and distributes electricity to approximately 459,000 retail customers in a 1,155 square mile area in southeastern Arizona. TEP also sells electricity to other utilities and power marketing entities, located primarily in the Western United States. TEP is a wholly-owned subsidiary of UNS Energy, a utility services holding company. UNS Energy is an indirect wholly-owned subsidiary of Fortis. </span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">BASIS OF PRESENTATION</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP's Condensed Consolidated Financial Statements and disclosures are presented in accordance with GAAP, including specific accounting guidance for regulated operations and the SEC's interim reporting requirements.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The Condensed Consolidated Financial Statements include the accounts of TEP and its subsidiaries. In the consolidation process, accounts of TEP and its subsidiaries are combined, and intercompany balances and transactions are eliminated. TEP jointly owns several generation facilities and transmission systems with both affiliated and non-affiliated entities. TEP records its proportionate share of: (i) jointly-owned facilities in Utility Plant on the Condensed Consolidated Balance Sheets; and (ii) operating costs associated with these facilities on the Condensed Consolidated Statements of Income. These Condensed Consolidated Financial Statements exclude some information and footnotes required by GAAP and the SEC for annual financial statement reporting and should be read in conjunction with the Consolidated Financial Statements and footnotes in TEP's 2025 Annual Report on Form 10-K.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The Condensed Consolidated Financial Statements are unaudited, but, in management's opinion, include all normal, recurring adjustments necessary for a fair statement of the results for the interim periods presented. Because weather and other factors cause seasonal fluctuations in sales, TEP's quarterly operating results are not indicative of annual operating results. To conform with the current period presentation, TEP combined four prior period Operating Expense line items: (i) Fuel; (ii) Purchased Power; (iii) Transmission and Other PPFAC Recoverable Costs; and (iv) Increase (Decrease) to Reflect PPFAC Recovery Treatment, into a single line item titled Fuel and Purchased Power on the Condensed Consolidated Statements of Income. Additionally, TEP has reclassified Income Taxes Receivable/Payable in the prior period from a separately disclosed line into Other, Net on the Condensed Consolidated Statements of Cash Flows to conform with the current period presentation. Both the change in presentation and reclassification had no impact on TEP’s results of operation, financial position, or cash flows.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">Variable Interest Entities</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">A VIE is an entity in which equity investors lack the characteristics of a controlling financial interest or do not have sufficient equity investment at risk for the entity to finance its activities without additional subordinated financial support. TEP regularly reviews contracts to determine if it has a variable interest in an entity, if that entity is a VIE, and if TEP is the primary beneficiary of the VIE. The primary beneficiary is required to consolidate the VIE when it has: (i) the power to direct activities that most significantly impact the economic performance of the VIE; and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP has entered into long-term renewable PPAs with various entities. Some of these entities are VIEs due to the long-term fixed price component in the agreements. These PPAs effectively transfer commodity price risk to TEP, the buyer of the power, creating a variable interest. TEP has determined it is not a primary beneficiary of these VIEs as it lacks the power to direct the activities that most significantly impact the economic performance of the VIEs. TEP regularly evaluates its primary beneficiary conclusions to determine if changes have occurred that impact its VIE assessment.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">As of September 30, 2026, the carrying amounts of assets and liabilities in the balance sheet that relate to variable interests under long-term renewable PPAs are predominantly related to working capital accounts and generally represent the amounts owed by TEP for the deliveries associated with the current billing cycle. TEP's maximum exposure to loss is limited to the cost of replacing the power if the providers do not meet the production guarantee. However, the exposure to loss is mitigated as the Company would likely recover these costs through cost recovery mechanisms. See Note 2 for additional information related to cost recovery mechanisms.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">REPORTABLE SEGMENTS</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP's principal business operations include generating, transmitting, and distributing electricity to its retail customers. In addition to retail sales, TEP sells electricity, transmission, and ancillary services to other utilities, municipalities, and energy marketing companies on a wholesale basis. TEP has one operating segment, its regulated utility operations. TEP’s CODM is Susan M. Gray who holds the position of Chief Executive Officer of TEP and its parent company, UNS Energy. The CODM uses net income to assess performance and decide how to allocate resources for UNS Energy overall (including employees and </span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">financial or capital resources) predominantly in the annual budget and forecasting process. Net income is reported on the Condensed Consolidated Statements of Income. Operations and Maintenance expense includes expenses reimbursed by third-parties and expenses related to customer-funded RES and DSM programs. Operations and Maintenance expense excluding these reimbursable and customer funded expenses totaled $87 million and $275 million for the three and nine months ended September 30, 2026, respectively, and $91 million and $261 million for three and nine months ended September 30, 2025, respectively. Total assets, the measure of segment assets, is reported on the Condensed Consolidated Balance Sheets. Capital expenditures are reported on the Condensed Consolidated Statements of Cash Flows.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">RESTRICTED CASH</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">Restricted cash includes cash balances restricted with respect to withdrawal or usage based on contractual or regulatory considerations.

energy community bonus credit, and PTCs. The ITC benefit associated with Roadrunner Reserve II is being recognized in 2026, while recognition of the Roadrunner Reserve I ITC benefit is substantially deferred until the effective date of new rates as established in the 2025 Rate Case.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">Investment Tax Credits </span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">Roadrunner Reserve II was placed in service in June 2026 and has generated approximately $130 million of ITCs, which includes a 10% energy community bonus credit. The amount of ITCs generated is subject to adjustments to qualifying project costs. TEP recorded a deferred tax asset with a corresponding regulatory liability to reflect the anticipated return of benefits to customers. TEP also recorded a valuation allowance against the deferred tax asset reflecting the discount in proceeds from a planned sale of ITCs to a third-party.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">In March 2026, TEP entered into an agreement to transfer ITCs related to Roadrunner Reserve II in the second half of 2026. In connection with the transfer of ITCs from Roadrunner Reserve II, TEP has agreed to provide customary indemnifications to the buyer for certain tax-related risks, including potential disallowance or recapture of credits. See Note 7 for additional information regarding tax credit transfer indemnifications. In July 2026, TEP transferred $50 million of the ITCs and received $46 million in cash proceeds. As of September 30, 2026, TEP had a $67 million deferred tax asset, net of the remaining $2 million valuation allowance, in Deferred Income Taxes, Net on the Condensed Consolidated Balance Sheets.

The update introduces recognition, measurement, presentation, and disclosure requirements, including: (i) classification of credits based on intended use (compliance versus noncompliance); (ii) initial measurement at cost with subsequent measurement models varying based on classification; and (iii) recognition and measurement of environmental credit obligations based on a “linked” approach, which reflects the cost of credits on hand, contractual arrangements, or current market prices. The guidance also requires expanded disclosures, including the intended use of credits, changes in the intended use of credits, and the nature and measurement of related obligations. The update is effective for public business entities beginning with annual and interim reporting periods that start on or after January 1, 2028. Entities are required to apply the guidance on a retrospective basis, with a cumulative-effect adjustment recorded to the opening retained earnings. Early adoption is permitted.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline">Targeted Improvements to the Accounting for Internal-Use Software</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">In September 2025, the FASB issued accounting guidance that updates the recognition criteria for internal-use software. The update removes references to software development project stages and requires capitalization of software costs once: (i) management has authorized and committed to funding the project; and (ii) it is probable that the project will be completed and the software will perform its intended function. Evaluating the probability that the project will be completed includes an assessment of whether significant development uncertainty exists. The amendment requires entities to apply the disclosure requirements applicable to property, plant, and equipment to all capitalized internal-use software costs, irrespective of financial statement presentation. The amendments are effective for annual and interim reporting periods beginning January 1, 2028. The guidance may be applied prospectively, retrospectively, or using a modified transition approach. Early adoption is permitted.

In January 2025, the FASB issued accounting guidance clarifying the effective date of this standard.

In September 2025, the Court of Appeals for the Eighth Circuit paused its consideration of legal challenges to the rules, pending further action by the SEC. In May 2026, the SEC proposed rescinding the March 2024 climate-related disclosure rules in their entirety. The proposal was published in the Federal Register in June 2026, and the public comment period with respect to such proposed rescission ended in August 2026. No final action has been taken, and the rules remain stayed and are not currently effective.

In the consolidation process, accounts of TEP and its subsidiaries are combined, and intercompany balances and transactions are eliminated. TEP jointly owns several generation facilities and transmission systems with both affiliated and non-affiliated entities. TEP records its proportionate share of: (i) jointly-owned facilities in Utility Plant on the Condensed Consolidated Balance Sheets; and (ii) operating costs associated with these facilities on the Condensed Consolidated Statements of Income. These Condensed Consolidated Financial Statements exclude some information and footnotes required by GAAP and the SEC for annual financial statement reporting and should be read in conjunction with the Consolidated Financial Statements and footnotes in TEP's 2025 Annual Report on Form 10-K.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The Condensed Consolidated Financial Statements are unaudited, but, in management's opinion, include all normal, recurring adjustments necessary for a fair statement of the results for the interim periods presented. Because weather and other factors cause seasonal fluctuations in sales, TEP's quarterly operating results are not indicative of annual operating results. To conform with the current period presentation, TEP combined four prior period Operating Expense line items: (i) Fuel; (ii) Purchased Power; (iii) Transmission and Other PPFAC Recoverable Costs; and (iv) Increase (Decrease) to Reflect PPFAC Recovery Treatment, into a single line item titled Fuel and Purchased Power on the Condensed Consolidated Statements of Income. Additionally, TEP has reclassified Income Taxes Receivable/Payable in the prior period from a separately disclosed line into Other, Net on the Condensed Consolidated Statements of Cash Flows to conform with the current period presentation. Both the change in presentation and reclassification had no impact on TEP’s results of operation, financial position, or cash flows.</span></div> <div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">Variable Interest Entities</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">A VIE is an entity in which equity investors lack the characteristics of a controlling financial interest or do not have sufficient equity investment at risk for the entity to finance its activities without additional subordinated financial support. TEP regularly reviews contracts to determine if it has a variable interest in an entity, if that entity is a VIE, and if TEP is the primary beneficiary of the VIE. The primary beneficiary is required to consolidate the VIE when it has: (i) the power to direct activities that most significantly impact the economic performance of the VIE; and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP has entered into long-term renewable PPAs with various entities. Some of these entities are VIEs due to the long-term fixed price component in the agreements. These PPAs effectively transfer commodity price risk to TEP, the buyer of the power, creating a variable interest. TEP has determined it is not a primary beneficiary of these VIEs as it lacks the power to direct the activities that most significantly impact the economic performance of the VIEs. TEP regularly evaluates its primary beneficiary conclusions to determine if changes have occurred that impact its VIE assessment.</span></div>As of September 30, 2026, the carrying amounts of assets and liabilities in the balance sheet that relate to variable interests under long-term renewable PPAs are predominantly related to working capital accounts and generally represent the amounts owed by TEP for the deliveries associated with the current billing cycle. TEP's maximum exposure to loss is limited to the cost of replacing the power if the providers do not meet the production guarantee. However, the exposure to loss is mitigated as the Company would likely recover these costs through cost recovery mechanisms. <div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">REPORTABLE SEGMENTS</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP's principal business operations include generating, transmitting, and distributing electricity to its retail customers.

The update introduces recognition, measurement, presentation, and disclosure requirements, including: (i) classification of credits based on intended use (compliance versus noncompliance); (ii) initial measurement at cost with subsequent measurement models varying based on classification; and (iii) recognition and measurement of environmental credit obligations based on a “linked” approach, which reflects the cost of credits on hand, contractual arrangements, or current market prices. The guidance also requires expanded disclosures, including the intended use of credits, changes in the intended use of credits, and the nature and measurement of related obligations. The update is effective for public business entities beginning with annual and interim reporting periods that start on or after January 1, 2028. Entities are required to apply the guidance on a retrospective basis, with a cumulative-effect adjustment recorded to the opening retained earnings.

The update removes references to software development project stages and requires capitalization of software costs once: (i) management has authorized and committed to funding the project; and (ii) it is probable that the project will be completed and the software will perform its intended function. Evaluating the probability that the project will be completed includes an assessment of whether significant development uncertainty exists. The amendment requires entities to apply the disclosure requirements applicable to property, plant, and equipment to all capitalized internal-use software costs, irrespective of financial statement presentation. The amendments are effective for annual and interim reporting periods beginning January 1, 2028. The guidance may be applied prospectively, retrospectively, or using a modified transition approach. Early adoption is permitted.

In September 2025, the Court of Appeals for the Eighth Circuit paused its consideration of legal challenges to the rules, pending further action by the SEC. In May 2026, the SEC proposed rescinding the March 2024 climate-related disclosure rules in their entirety. The proposal was published in the Federal Register in June 2026, and the public comment period with respect to such proposed rescission ended in August 2026. No final action has been taken, and the rules remain stayed and are not currently effective.

The ACC also waived for TEP the general requirement that Arizona utilities file an annual RES implementation plan.

If approved, the ACC could submit the order repealing the RES directly to the Secretary of State of Arizona. TEP cannot predict the timing or outcome of this proceeding and is continuing to evaluate the potential impacts on its regulatory obligations and financial position.

The 2026 Credit Agreement is an unsecured credit agreement with a maturity date of October 2031 that provides for revolving credit and LOC facilities and allows for two one-year extensions if certain conditions are satisfied. Terms of the 2026 Credit Agreement include a: (i) $350 million revolving credit facility, with a $15 million swingline sublimit; and (ii) $50 million LOC sublimit. Interest rates and fees are based on a pricing grid tied to TEP's credit ratings. Amounts borrowed under the 2026 Credit Agreement will be used for working capital and other general corporate purposes. LOCs may be issued from time to time to support energy procurement, hedging transactions, and other business activities. On October 22, 2026, TEP amended and reduced a $1 million LOC with fees accruing at a rate of 1.000% per annum to less than $1 million.

The estimated liability for final mine reclamation depends on assumptions, such as projected costs, timing, and inflation. When these assumptions change, TEP adjusts future expense recognition over the remaining term of the applicable coal supply agreement. TEP’s PPFAC allows the pass-through of final mine reclamation costs to retail customers as part of fuel costs. Therefore, TEP defers these expenses by recording a regulatory asset and a reclamation liability over the remaining life of the respective coal supply agreement. TEP recovers the regulatory asset through the PPFAC as final mine reclamation costs are funded. After expiration of the related coal supply agreement, any changes in the estimated liability are recorded to both the regulatory asset and reclamation liability.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP is responsible for a portion of final mine reclamation costs for the mines at Four Corners and San Juan. TEP’s liability related to Four Corners totaled $2 million and $3 million as of September 30, 2026, and December 31, 2025, respectively, and was recorded in Current Liabilities—Other and Other Noncurrent Liabilities on the Condensed Consolidated Balance Sheets. TEP's Four Corners coal supply agreement expires in 2031.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP ceased operations at San Juan in 2022 following expiration of its coal supply agreement. TEP’s remaining final mine reclamation liability at San Juan was $17 million and $23 million as of September 30, 2026, and December 31, 2025, respectively, and was recorded in Current Liabilities—Other and Other Noncurrent Liabilities on the Condensed Consolidated Balance Sheets. TEP established a trust to fund its share of estimated final mine reclamation costs at San Juan that will remain in effect until reclamation activities are completed, which are currently projected to be completed in 2040. See Note 1 for additional information on restricted cash related to reclamation and decommissioning costs at San Juan. </span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">Tax Credit Transfer Indemnification</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">In connection with the transfer of federal ITCs, TEP provided indemnities to the purchaser for certain losses arising from the disallowance, reduction, or recapture of the transferred ITCs. TEP’s maximum exposure under these indemnities is limited to 125% of the transferred ITCs. The indemnities remain in effect through the applicable tax statute of limitations period, plus 90 days. As of September 30, 2026, no claims had been asserted, and no liability had been recorded.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">FERC Market-Based Rate Authority</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">On October 30, 2026, FERC issued an order revoking TEP’s market-based rate authority for wholesale power sales within the TEP balancing authority area. As a result, such sales are required to be made at FERC-approved cost-based rates. The order establishes a refund date of January 29, 2026, and requires refunds to any applicable wholesale power purchasers of amounts collected above the applicable cost-based rate.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP is evaluating the affected transactions and the applicable cost-based rates in response to the FERC order to determine the amount of any refunds that may be required. Any such refunds are expected to be eligible for recovery through the PPFAC. TEP is also considering whether to propose tailored mitigation that, if approved by the FERC, would apply prospectively as an alternative to cost-based rates. TEP does not expect the FERC order and related refunds to have a material impact on its financial position, results of operations, cash flows and disclosures.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">Performance Guarantees</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP participates in joint generation agreements at Four Corners and Luna, which expire in 2041 and 2046, respectively. Under these agreements, all participants, including TEP, guarantee certain performance obligations. If a participant defaults on payment, the non-defaulting participants must cover a proportionate share of expenses otherwise payable by the defaulting participant. In return, the non-defaulting participants are entitled to receive a proportionate share of the defaulting participant's generation capacity. For Luna, there is no maximum potential payment under this guarantee. For Four Corners, the maximum potential payment for non-defaulting participants is $250 million. As of September 30, 2026, no payment defaults have occurred under either agreement. </span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The Navajo and San Juan participation agreements expired in 2019 and 2022, respectively, but certain performance obligations continue through the decommissioning of both generation facilities.

These requirements are subject to interpretation and may be clarified by court decisions. Because these laws and regulations continue to evolve, TEP is unable to predict the impact of the changing laws and regulations on its operations or consolidated financial results. TEP expects to recover environmental compliance costs through customer rates. TEP believes it is in material compliance with applicable environmental laws and regulations.</span></div> 160 100 100 400 2000000 3000000 17000000 23000000 1.25 P90D 0 0 true 250000000 0 EMPLOYEE

Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP enters into various derivative and non-derivative contracts to reduce exposure to energy price risk associated with its natural gas and purchased power requirements. The objectives for entering into such contracts include: (i) creating price stability; (ii) meeting load and reserve requirements; and (iii) reducing exposure to price volatility that may result from delayed recovery under the PPFAC mechanism. In addition, TEP enters into derivative and non-derivative contracts to optimize the system's generation resources by selling power in the wholesale market for the benefit of TEP's retail customers.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP primarily applies the market approach for recurring fair value measurements. When TEP has observable inputs for substantially the full term of the asset or liability or uses quoted prices in an inactive market, it categorizes the instrument in Level 2. TEP categorizes derivatives in Level 3 when an aggregate pricing service or published prices that represent a consensus reporting of multiple brokers is used.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">For both purchased power and natural gas prices, TEP obtains quotes from brokers, major market participants, exchanges, or industry publications and relies on its own price experience from active transactions in the market. TEP primarily uses one set of quotations each for purchased power and natural gas and then validates those prices using other sources. TEP believes that the market information provided is reflective of market conditions as of the time and date indicated.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">Published prices for energy derivative contracts may not be available due to the nature of contract delivery terms such as non-standard time blocks and non-standard delivery points. In these cases, TEP applies adjustments based on historical price curve relationships, transmission costs, and real power line losses.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP also considers the impact of counterparty credit risk using current and historical default and recovery rates, as well as its own credit risk using credit default swap data.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The inputs and TEP's assessments of the significance of a particular input to the fair value measurements require judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. TEP evaluates the assumptions underlying its price curves monthly.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%">Energy Derivative Contracts, Regulatory Recovery</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP enters into energy contracts that are considered derivatives and qualify for regulatory recovery.

and purchased power requirements. The objectives for entering into such contracts include: (i) creating price stability; (ii) meeting load and reserve requirements; and (iii) reducing exposure to price volatility that may result from delayed recovery under the PPFAC mechanism. In addition, TEP enters into derivative and non-derivative contracts to optimize the system's generation resources by selling power in the wholesale market for the benefit of TEP's retail customers.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">TEP primarily applies the market approach for recurring fair value measurements. When TEP has observable inputs for substantially the full term of the asset or liability or uses quoted prices in an inactive market, it categorizes the instrument in Level 2. TEP categorizes derivatives in Level 3 when an aggregate pricing service or published prices that represent a consensus reporting of multiple brokers is used.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">For both purchased power and natural gas prices, TEP obtains quotes from brokers, major market participants, exchanges, or industry publications and relies on its own price experience from active transactions in the market. TEP primarily uses one set of quotations each for purchased power and natural gas and then validates those prices using other sources. TEP believes that the market information provided is reflective of market conditions as of the time and date indicated.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">Published prices for energy derivative contracts may not be available due to the nature of contract delivery terms such as non-standard time blocks and non-standard delivery points.
