COVID-19 Summary . Primary focus is on the safety of our customers and employees while providing reliable energy service. . Implemented business continuity plans and we believe that we will continue to be able to conduct our utility operations effectively. . We have informed retail customers and state regulators that disconnections and late fees for non-payment are temporarily suspended. . Although we have not experienced any significant supply chain issues to date, there could be negative impacts on the ability of suppliers, vendors or contractors to perform. . Successfully transitioned more than 1,300 employees to work remotely. . Our foundation's charitable giving across our service territory totals more than $1.1 million, and includes more than $865 thousand dollars toward relief from the impacts of COVID-19. 5

COVID-19 Financial Impacts . April electric loads were a 5% overall decline, with a 10% increase in residential, a 12% decrease in commercial and a 14% decrease in industrial. Natural gas loads were within normal bounds for the time of year. . We have decoupling and other regulatory mechanisms in Washington, Idaho and Oregon, which mitigate the impact of lower loads and revenues for residential and certain commercial customer classes. Over 90 percent of our utility revenue is covered by regulatory mechanisms. . Bad debt expense is expected to increase $5 million for the full year of 2020, including $1.6 million recognized in the first quarter of 2020. . We expect to offset some of the negative impacts of COVID-19 at Avista Utilities with cost savings, and we have filed petitions for an accounting order in each of our jurisdictions to defer the recognition of COVID-19 expenses as well as identified cost savings of other COVID-19 related benefits. . We do not expect the impact of COVID-19 to change our estimate of Avista Utilities’ capital expenditures of about $405 million in 2020. It is possible that prolonged economic distress or business interruptions could cause a decrease in our utility capital expenditures. . We are expecting additional losses at non-utility businesses for the remainder of the year due to overall market declines, including the impacts of COVID-19. . Improved liquidity through a $100 million credit agreement in April. 6

Increased or new risks may arise from severe weather or natural disasters, including wildfires; industry and geographic concentrations which could increase our exposure to credit risks due to counterparties, suppliers and customers being similarly affected by changing conditions; deterioration in the creditworthiness of our customers; Energy Commodity Risk volatility and illiquidity in wholesale energy markets, including exchanges, the availability of willing buyers and sellers, changes in wholesale energy prices that could affect operating income, cash requirements to purchase electricity and natural gas, value received for wholesale sales, collateral required of us by individual counterparties and/or exchanges in wholesale energy transactions and credit risk to us from such transactions, and the market value of derivative assets and liabilities; default or nonperformance on the part of any parties from whom we purchase and/or sell capacity or energy; potential environmental regulations or lawsuits affecting our ability to utilize or resulting in the obsolescence of our power supply resources; explosions, fires, accidents, pipeline ruptures or other incidents that could limit energy supply to our facilities or our surrounding territory, which could result in a shortage of commodities in the market that could increase the cost of replacement commodities from other sources; Compliance Risk changes in laws, regulations, decisions and policies at the federal, state or local levels, which could materially impact both our electric and gas operations and costs of operations; and the ability to comply with the terms of the licenses and permits for our hydroelectric or thermal generating facilities at cost-effective levels.
