Update to credit analysis Summary Avista Corporation's (Avista) credit profile reflects its primary business as a low-risk vertically integrated electric and gas utility with supportive cost recovery mechanisms, such as electric and gas decoupling. These supportive mechanisms have resulted in steady revenue and cash flow and sustained stable credit metrics over the last three years including the ratio of cash flow from operation before changes in working capital (CFO pre-WC) to debt at about 15%. Given a lag in rate case filings due to the coronavirus pandemic, we see the ratio weakening over the next 12 to 18 months to below 13%, which is below our indicated financial metric threshold for a possible downgrade. We expect Avista's financial metrics to rebound once new rates take effect at the conclusion of its currently pending general rate case. The credit further incorporates the company's adequate track record with its primary regulator, the Washington Utilities and Transportation Commission (WUTC), which regulates roughly 60% of the company's rate base and revenue. While we consider the last two Washington rate case outcomes as neutral from a credit perspective, the company has had a somewhat contentious regulatory relationship in the past particularly related to credit supportive mechanisms that would allow for faster cost recovery. The company stands to benefit from a clearer regulatory structure after the enactment of legislation that aims to reform the regulatory framework and pave the way for multiyear rate plans and performance based ratemaking. The bill could enhance the consistency and predictability of utility regulation and provide credit positive opportunities for Avista. However, improved regulatory and financial outcomes for these utilities remain subject to the bill's implementation by the WUTC. Avista has some unregulated exposure and owns regulated utility Alaska Electric Light and Power (AEL&P, Baa3 stable) that provides marginal operational and cash flow diversity, but remain neutral in terms of our view of Avista's credit.

We expect the company's CFO pre-W/C to debt to return to the mid-teens after the conclusion of its current rate case and new rates take effect in 2022. In addition, the stable outlook assumes that Avista will continue to receive adequate cost recovery authorizations within its regulatory jurisdictions and that unregulated operations will remain below 15% of consolidated earnings and cash flow. Factors that Could Lead to an Upgrade An upgrade could occur if financial metrics improve such that CFO pre-WC to debt is above 19% and CFO pre-WC less dividend is above 13% on a consistent basis. Additionally, a demonstrated improvement in the regulatory environment, including implementation of credit positive legislative provisions, could lead to a higher rating. Factors that Could Lead to a Downgrade A rating downgrade could result should there be a degradation in the company's regulatory environment resulting in inadequate cost recovery or CFO pre-WC to debt remains below 14% for a sustained period.

Source: Moody's Financial Metrics Profile Avista is primarily an electric and natural gas utility whose Avista Utilities operating division provides electric transmission and distribution, and natural gas distribution services in parts of eastern Washington and northern Idaho. Avista Utilities also provides natural gas distribution service in parts of northeastern and southwestern Oregon. The utility has electric generating facilities in Washington, Idaho, Oregon and Montana and also supplies electricity to a small number of customers in Montana. For the three months ended 31 March 2021, Avista Utilities had over 397,000 electric and over 363,000 gas customers. Avista owns Alaska Energy and Resources Company (AERC; not rated), parent of Alaska Electric Light and Power Company (AEL&P; Baa3 stable) which serves around 17,000 electric customers in Juneau, Alaska. Avista's utility operations are regulated by the Washington Utilities and Transportation Commission (WUTC), the Idaho Public Utilities Commission (IPUC), the Oregon Public Utility Commission (OPUC) and the Montana Public Service Commission (MPSC). AEL&P is under the purview of the Regulatory Commission of Alaska (RCA).

CFO pre-WC to debt stabilized in the mid-teens over the last three years after declining from about 20% in 2017 following the loss of deferred taxes post tax reform. 3 10 August 2021 Avista Corp.: Update to credit analysis Staff_PR_139 Attachment A Page 3 of 13 MOODY'S INVESTORS SERVICE INFRASTRUCTURE AND PROJECT FINANCE As highlighted in Exhibit 5, CFO pre-WC to debt in 2021 is forecast to drop below 13% over the next 12 to 18 months driven by a delay in the company's rate case filing due to the coronavirus pandemic. Avista filed general rate cases in Washington and Idaho in late 2020, which are the drivers behind our expectations of an improved CFO pre-W/C to debt ratio in 2023. Because of historic test year requirements, Avista experiences cash flow lag. Management had intended to improve this lag by filing rate cases more frequently, but the coronavirus driven economic downturn delayed plans to file until late 2020. Any outcome of these rate cases will not be effective until late 2021. The company's financial buffer will be limited over the next several years, with any improvement largely dependent of the outcome of the pending rate cases.

The Washington Utilities and Transportation Commission (WUTC), which regulates roughly 62% of the company's rate base and revenue, has electric and gas decoupling mechanisms which allow for timely recovery of fixed costs for the utility and drive stable and predictable gross margin and cash flow in the face of declining use. Even so, the use of historic test years results in the need for Avista to file general rate cases frequently to recover and earn on investments. Avista filed an electric and natural gas general rate case on 30 October 2020 with WUTC requesting an increase in base electric revenue of $44.2 million (or 8.3%) and an increase in natural gas revenue of $12.8 million (or 12.2%). The company proposed that the revenue increases be offset by the creation of a Tax Customer Credit, which would come from a change in its accounting for federal income tax expense. The revenue increases are premised on a 9.9% ROE and a 50% equity layer; higher than the currently approved 9.4% and 48.5%. The company expects the rate case to be completed and new rates to become effective on 1 October 2021. The company's prior electric and natural gas general rate cases filed on 30 April 2019 resulted in a partial settlement and the WUTC approved the settlement agreement in March 2020. The partial settlement allowed for a one year rate plan increasing electric revenue by $28.5 million and natural gas revenue by $8 million effective 1 April 2020. The agreement approved an ROE of 9.4% and equity layer of 48.5%, which are slightly below industry averages. Additionally, the settlement included provisions for cost recovery associated with Colstrip units 3 and 4 decommissioning and remediation (D&R) expenses estimated at about $33 million as of 31 March 2020 and the ability to accelerate depreciation to 2025 in recognition of the state's new energy bill requirements. The order disallowed Avista recovery of costs associated with a 2018 Colstrip plant outage, ruling that Avista failed to prove the costs were prudently incurred, a credit negative. The total costs were about $3 million. The original filing was for a two-year rate plan that included a $45.8 million increase in annual electric revenue and a $12.9 million increase in annual natural gas revenue effective April 2020 and a $18.9 million increase for annual electric revenue and a $6.5 million increase for annual natural gas revenue effective April 2021. The request was based on a 9.9% ROE and 50% equity layer. 4 10 August 2021 Avista Corp.: Update to credit analysis Staff_PR_139 Attachment A Page 4 of 13 MOODY'S INVESTORS SERVICE INFRASTRUCTURE AND PROJECT FINANCE Idaho In Idaho, Avista filed its 2021 general rate case with the Idaho Public Utilities Commission (IPUC) on 29 January 2021. The request is for a two year rate plan with new rates effective 1 September 2021 and 1 September 2022. In June 2021, the company reached an all parties settlement, which has been submitted to the IPUC for approval. The electric and natural gas rate plan is based on a 9.9% ROE, an increase from current 9.5%, and a 50% equity ratio, in line with currently approved equity ratio and requests an electric base revenue increase of $24.8 million (10.1%) in 2021 and an $8.7 million (3.2%) increase in 2022. Similarly to the Washington filing, Avista has requested that the revenue increase be offset by the creation of the Tax Customer Credit for the two years. Avista reached an all parties settlement on 11 October 2019 for its last electric general rate case filed on 10 June 2019. The settlement, which was approved by the IPUC on 1 December 2019, included a revenue reduction of $7.18 million effective 1 December 2019. The approved revenue decrease was based on a 9.5% ROE and a 50% equity ratio, which were in line with prior approved levels. Avista requested a revenue increase of about $5.3 million that included costs associated with its wind generation PPAs in base rates instead of a continuation of the Power Cost Adjustment (PCA) mechanism. The settlement approved continuation of the PCA instead of their inclusion in base rates. Avista was authorized electric and gas decoupling mechanisms, known as Fixed Cost Adjustment (FCA) in Idaho in December 2015 for a three-year period beginning 1 January 2016. The company filed a request for continuation, and the IPUC approved the request on 17 December 2019. Oregon The company's most recent natural gas rate case filed on 16 March 2020 resulted in a settlement that included a $3.9 million base rate revenue increase, down from the requested $6.8 million, with rates effective on 16 January 2021. The settlement maintained the 9.4% ROE and the 50% equity layer. The company intends to file a new general rate case in the second half of 2021. As part of a March 2016 rate case order in Oregon, Avista is allowed to implement a revenue per customer decoupling mechanism. Alaska AELP lowered customer rates by 6.7% or $2.4 million annually effective 1 August 2018 to reflect the lower tax rate associated with tax reform. The RCA also approved AELP's proposal to refund to customers a one-time credit equal to the 6.7% rate reduction for 1 January through 31 July 2018. The utility completed the refund during the third quarter of 2018. The impact of the TCJA on AELP’s deferred income taxes will be addressed in its next general rate case filing. AELP planned to file a general rate case in August 2021, however, the company requested a delay in filing to avoid using 2020 as a test year given coronavirus pandemic and the resources it would take to normalize 2020 for the filing. AELP is under regulatory order by the commission to file by 2022 with a 2021 test year. AELP's allowed ROE of 11.95% and equity layer of 58.18% is above the average of authorized returns for the industry, a credit positive. However, we note that Alaska has a statutory period of 450 days or approximately 15 months to decide on rate cases, the longest in the nation and has not authorized cash flow stabilizing mechanisms such as revenue decoupling. Washington's legislative action has the potential to enhance regulatory framework The Washington regulatory framework has the potential to be enhanced with the enactment of two key Senate bills (SB), SB 5116 and SB 5295 in 2019 and 2021,respectively. SB 5116, a clean energy bill with aggressive carbon transition targets, was enacted in 2019 and offered utilities the potential for important regulatory tools to recover associated costs. The bill requires electric utilities to eliminate coal-fired generation by 2025, transition the state's electricity supply to 80% renewables and 100% carbon neutral power by 2030 and be 100% carbon free by 2045. We viewed the law as credit positive because it includes the potential for enhanced cost recovery mechanisms that can improve utility financial performance and provides a legal and regulatory framework to reduce carbon exposure risks. Compliance with the law will require significant investment and an overhaul of existing state electric infrastructure. However, the law acknowledges the WUTC's authority to implement performance and incentive based regulation, multiyear rate plans and other “flexible regulatory mechanisms” to achieve the state's public interest objectives. Importantly, the law also recognizes that the policy must include safeguards that do not impair the reliability of the electricity system nor impose unreasonable costs on utility customers. We discuss more details on SB 5295 in “Washington approves clean energy bill, a credit positive for investor-owned utilities” (16 May 2019). 5 10 August 2021 Avista Corp.: Update to credit analysis Staff_PR_139 Attachment A Page 5 of 13 MOODY'S INVESTORS SERVICE INFRASTRUCTURE AND PROJECT FINANCE The recently passed SB 5295 (enacted on 3 May 2021) followed the clean energy bill and aims at reforming the regulatory framework for utilities in the state by paving the way for multiyear rate plans (MYRP) and performance based ratemaking (PBR). We view the bill as credit positive as it could enhance the consistency and predictability of utility regulation. Specifically, we view the PBR construct as a credit supportive rate making mechanism because MYRPs with performance targets and the potential to earn performance incentives will work to reduce regulatory lag. It could also aid Avista's renewable transition, improve operational efficiency and enhance cash flow and profitability, all while considering customer cost and service. Nevertheless, the extent to which the new law will enhance the Washington regulatory framework and improve utility financial performance is subject to WUTC decisions, which have been historically inconsistent. The bill requires the WUTC to develop, in collaboration with utilities and other interested stakeholders, a policy statement on alternatives to traditional costs of service rate making, including performance measures, incentives and penalty mechanisms. The WUTC must provide an update to the relevant legislative committees by 1 January 2022. Importantly, beginning 1 January 2022, utilities are required to include a proposal for a MYRP between two and four years in length in every general rate case filing. We discuss more details on SB 5295 in “Legislation supporting multiyear rate plans has credit positive implications for Washington's investor owned utilities” (10 May 2021). ESG considerations Avista's ESG Credit Impact Score is CIS-3 (Moderately Negative). Exhibit 6 ESG Credit Impact Score Source: Moody's Investors Service Avista’s ESG Credit Impact Score is moderately negative (CIS-3), where its ESG attributes are overall considered as having a limited impact on the current rating, with greater potential for future negative impact over time. Avista’s CIS-3 reflects its moderate exposure to environmental risks and social risks, and low exposure to governance risks. Exhibit 7 ESG Issuer Profile Scores Source: Moody's Investors Service 6 10 August 2021 Avista Corp.: Update to credit analysis Staff_PR_139 Attachment A Page 6 of 13 MOODY'S INVESTORS SERVICE INFRASTRUCTURE AND PROJECT FINANCE Environmental Specifically, Avista’s exposure to environmental risks is moderate (E-3 issuer profile score) driven by its moderately negative physical climate risks, primarily in the form of extreme weather patterns including an increase in wildfires across Washington. These risks are offset by a neutral to low exposure to carbon transition, water management, waste and pollution and natural capital. Social Exposure to social risks is moderately negative (S-3 issuer profile score) reflecting the higher risk to demographics and societal trends that increase public concern over environmental, social or affordability issues, which could lead to adverse regulatory political intervention. These risks are balanced by neutral to low risks to health and safety, human capital, customer relationships and responsible production. Governance Governance is broadly in line with other utilities and does not pose a particular risk (G-2 issuer profile). For Avista, board structure primarily stands out as moderately negative, however it is offset by other aspects of governance strength that are derived in part by government ownership, compliance and reporting, management credibility and track record as well as financial policy and risk management, which is driven by the historical ratio of retained cash flow to debt. 7 10 August 2021 Avista Corp.: Update to credit analysis Staff_PR_139 Attachment A Page 7 of 13 MOODY'S INVESTORS SERVICE INFRASTRUCTURE AND PROJECT FINANCE Liquidity Analysis We expect Avista to maintain adequate liquidity over the next 12-18 months. Avista's external liquidity sources consist of a $400 million senior secured revolving credit facility which expires in June 2026. As of 30 April 2021, there was about $182 million available under the line of credit. Since Avista currently has unsecured investment-grade ratings from two nationally recognized rating agencies, the company has the option to request the banks to relinquish their existing First Mortgage Bond collateral position. Avista has not asked for the release, keeping the company as one of the few US regulated utilities to maintain a secured bank credit facility. Avista was in compliance with the facility’s sole covenant of less than 65% capitalization, with a ratio of 53.5% as of 30 June 2021. We note that the company has no material adverse change language beyond the close of the facility, a credit positive. AELP has a $25 million line of credit which expires in 2024 and requires a consolidated debt to capitalization covenant of 67.5%. As of 31 March 2021, there were no borrowings or letters of credit outstanding under the facility and AELP was in compliance with its covenant, with a ratio of 52%. The company typically funds capex with a mix of long-term debt and equity. In 2021, Avista expects to issues about $140 million in long-term debt and $90 million in equity. The company's maturity schedule is manageable with the next maturity in 2022, as shown in Exhibit 8. Avista entered into $100 million 364-day term loan in April 2020 to support liquidity; as of April 2021 the agreement had been repaid. Exhibit 8 Avista Corp.

Moody’s Investors Service, Inc., a wholly-owned credit rating agency subsidiary of Moody’s Corporation (“MCO”), hereby discloses that most issuers of debt securities (including corporate and municipal bonds, debentures, notes and commercial paper) and preferred stock rated by Moody’s Investors Service, Inc. have, prior to assignment of any credit rating, agreed to pay to Moody’s Investors Service, Inc. for credit ratings opinions and services rendered by it fees ranging from $1,000 to approximately $5,000,000. MCO and Moody’s Investors Service also maintain policies and procedures to address the independence of Moody’s Investors Service credit ratings and credit rating processes. Information regarding certain affiliations that may exist between directors of MCO and rated entities, and between entities who hold credit ratings from Moody’s Investors Service and have also publicly reported to the SEC an ownership interest in MCO of more than 5%, is posted annually at www.moodys.com under the heading “Investor Relations — Corporate Governance — Director and Shareholder Affiliation Policy.” Additional terms for Australia only: Any publication into Australia of this document is pursuant to the Australian Financial Services License of MOODY’S affiliate, Moody’s Investors Service Pty Limited ABN 61 003 399 657AFSL 336969 and/or Moody’s Analytics Australia Pty Ltd ABN 94 105 136 972 AFSL 383569 (as applicable).

Additional terms for Japan only: Moody's Japan K.K. (“MJKK”) is a wholly-owned credit rating agency subsidiary of Moody's Group Japan G.K., which is wholly-owned by Moody’s Overseas Holdings Inc., a wholly-owned subsidiary of MCO. Moody’s SF Japan K.K. (“MSFJ”) is a wholly-owned credit rating agency subsidiary of MJKK. MSFJ is not a Nationally Recognized Statistical Rating Organization (“NRSRO”). Therefore, credit ratings assigned by MSFJ are Non-NRSRO Credit Ratings. Non-NRSRO Credit Ratings are assigned by an entity that is not a NRSRO and, consequently, the rated obligation will not qualify for certain types of treatment under U.S. laws. MJKK and MSFJ are credit rating agencies registered with the Japan Financial Services Agency and their registration numbers are FSA Commissioner (Ratings) No. 2 and 3 respectively. MJKK or MSFJ (as applicable) hereby disclose that most issuers of debt securities (including corporate and municipal bonds, debentures, notes and commercial paper) and preferred stock rated by MJKK or MSFJ (as applicable) have, prior to assignment of any credit rating, agreed to pay to MJKK or MSFJ (as applicable) for credit ratings opinions and services rendered by it fees ranging from JPY125,000 to approximately JPY550,000,000. MJKK and MSFJ also maintain policies and procedures to address Japanese regulatory requirements.
