Avista Reaches Settlement Agreement on Electric and Natural Gas Rate Cases with Idaho Public Utilities Commission and Partners

Avista Corp and several parties have submitted a settlement to the Idaho Public Utilities Commission that, if approved, would increase annual base electric revenues by $19.5 million (6.3%) starting September 1, 2025, followed by a $14.7 million (4.5%) increase in 2026; natural gas revenues would increase by $4.6 million (9.2%) in 2025 but decrease by $0.2 million (0.4%) in 2026. The agreement, designed to provide fair rates and maintain infrastructure, would raise residential electric bills by approximately $6.95 per month in 2025 and natural gas bills by $4.11, though these increases are notably lower than Avista's original request.

Analysis

Avista Corporation has submitted a settlement agreement to the Idaho Public Utilities Commission which, if approved, would increase annual base electric revenues by $19.5 million (6.3%) effective September 1, 2025, and by an additional $14.7 million (4.5%) effective September 1, 2026. Natural gas base revenues are slated to rise by $4.6 million (9.2%) from September 1, 2025, but then decrease by $0.2 million (0.4%) effective September 1, 2026. The settlement targets a 9.6% return on equity (ROE) with a 50% common equity ratio and a 7.28% rate of return on rate base, aimed at supporting infrastructure investment and service reliability. These approved figures are substantially lower than Avista's original request, which sought a $43.0 million increase for electric and $8.8 million for natural gas in 2025, indicating regulatory compromise that may impact financial projections. For residential customers, this translates to an estimated $6.95 monthly electric bill increase in 2025. Recent insider trading activity for Avista (AVA) shows a pattern of selling, with 8 sales and zero purchases by insiders over the past six months. Institutional ownership changes in Q1 2025 were mixed; 206 institutions increased their holdings while 154 decreased positions, notable for significant reductions by the Public Sector Pension Investment Board (-93.0%) and Blackrock, Inc. (-13.1%), contrasting with substantial additions by Millennium Management LLC (+531.2%) and Jane Street Group, LLC.

Key Decisions for Investors

• Investors should view the proposed rate increases as supportive of Avista's revenue and targeted 9.6% ROE, but recognize that the settlement amounts are considerably below the company's initial requests, potentially tempering future earnings growth.
• The consistent pattern of insider sales over the last six months, coupled with significant divestitures by some large institutional investors, warrants careful consideration despite new interest from other funds.
• Monitor the implementation and customer impact of these rate changes, as well as the slight projected decrease in natural gas revenues for 2026, for their effects on Avista's financial performance and ability to fund its capital programs.
