Entergy Arkansas has demonstrated a positive financial trajectory, reflecting its strategic investments and favorable market conditions. For the third quarter of 2025, net income increased by $6 million to $191.74 million, compared to $185.77 million in the third quarter of 2024. This growth was primarily fueled by higher volume/weather and an increase in retail electric prices. Looking at the nine months ended September 30, 2025, net income saw a substantial increase of $128.60 million, reaching $377.46 million, up from $248.85 million in the prior year period. This significant improvement was largely due to the absence of a $131.80 million regulatory asset write-off in March 2024 related to the opportunity sales proceeding, alongside continued strong volume/weather and retail electric price gains.

Operating revenues for the third quarter of 2025 stood at $864.06 million, a notable increase from $662.15 million in the same period of 2024. For the nine months ended September 30, 2025, operating revenues reached $2.18 billion, up from $1.89 billion in the corresponding period of 2024. The volume/weather variance was a key driver, contributing $48.70 million in Q3 2025 and $98.10 million for the nine-month period. This was primarily due to increased industrial usage, particularly from large industrial customers in the primary metals and technology industries, and a rise in residential customers. Retail electric price increases, mainly from formula rate plan adjustments effective January 2025, added $20.40 million to Q3 revenues and $50.10 million for the nine-month period.

Operational efficiency and cost management remain critical. Other operation and maintenance expenses increased in Q3 2025 by $9.60 million due to higher vegetation maintenance costs and $4.30 million from increased incentive-based accruals. For the nine-month period, these expenses rose due to higher non-nuclear generation expenses ($15.30 million) and power delivery costs ($4.80 million), partially offset by a decrease in nuclear generation expenses ($6.60 million) and the absence of certain 2024 contract costs. Depreciation and amortization expenses also increased due to additions to plant in service, including the Walnut Bend, West Memphis, and Driver Solar facilities placed in service in late 2024.

From a liquidity perspective, net cash flow provided by operating activities for the nine months ended September 30, 2025, increased by $244.90 million. This was significantly bolstered by $160.20 million from the sale of nuclear and solar production tax credits and higher customer collections. Net cash flow used in investing activities decreased by $355.50 million, largely due to substantial payments in 2024 for solar facility purchases. Entergy Arkansas's debt to capital ratio stood at 53.10% as of September 30, 2025, a slight improvement from 53.60% at December 31, 2024, indicating a stable capital structure.

Strategic Outlook and Capital Deployment

Entergy Arkansas is embarking on an ambitious capital investment plan, anticipating approximately $7.60 billion in investments from 2026 through 2029. This includes $2 billion in 2026, $2.20 billion in 2027, $1.90 billion in 2028, and $1.50 billion in 2029.
