Avista reported a much larger top line in the latest reported period. Revenue rose from $403 million to $570 million versus the comparable period, while operating income more than doubled from $60 million to $134 million.
Net income climbed from $29 million to $92 million, and operating margin widened to 23.5% from 14.9%. On the surface, reported earnings increased considerably.
The more revealing number is utility margin, which strips out resource costs and many regulatory pass-throughs. It rose only to $349 million from $347 million. Avista's revenue got a $167 million lift; the measure closer to the economics of serving customers moved by $2 million.
The company's own reconciliation shows why the top line needs careful handling. Electric utility margin fell $3 million, while natural-gas utility margin rose $5 million, primarily from general rate cases. Electric decoupling revenue increased $14 million, but a Washington rate-refund provision and lower transportation revenue offset part of the reported revenue movement.
Avista described the electric result this way:
"Electric utility margin decreased $3 million primarily due to the removal of revenues related to the recovery of Colstrip capital and operating costs, partially offset by other effects of our general rate cases."

That is the central distinction in the numbers. Regulatory treatment can move reported revenue without moving utility margin by the same amount. Natural-gas retail revenue, for example, fell $50 million because of lower rates and sales volumes, while the company said those rate changes and rebates did not affect utility margin.
The cash picture adds a second complication. Cash declined from $44 million to $18 million, even as capital-spending intensity declined and free-cash-flow margin improved. The balance is not a cash-flow statement, and the 10-Q points to working-capital timing in the comparison.
Avista said changes in payables and other current liabilities reduced operating cash flow by $37 million versus the year-earlier period. The company attributed that change to the timing of a litigation settlement accrual and lower payables for natural-gas purchases as purchased volumes declined.
"Changes in other current liabilities and accounts payable decreased operating cash flows by $37 million compared to the first quarter of 2025, primarily due to the timing of a litigation settlement accrual during the first quarter of 2025, as well as decreased payables for natural gas purchases as volumes purchased in 2026 decreased."

The balance sheet did not show a comparable change in capital structure. Total debt was $3.3 billion at March 31, while shareholders' equity increased by $67 million, primarily from net income and common-stock issuance, partly offset by dividends.
That leaves a business with sharply higher reported earnings, nearly unchanged utility margin, and a smaller cash balance. At the latest close, Avista shares were $39.63, down 2.0% on the day. The price move is observable; the filing does not assign it a cause.
Avista's next reported period can be read against one clean baseline: the $349 million utility margin, alongside the cash-flow effect from payables and natural-gas purchases. Those figures will show whether the current earnings lift is still arriving mainly through utility economics or through regulatory and timing items.
