NorthWestern Energy (NWE) Q3 2026 Earnings Call Transcript

NorthWestern Energy reported Q3 2026 GAAP diluted EPS of $0.50, down from $0.62 a year earlier, and adjusted EPS of $0.58 versus $0.79; revenue increased 9.5% to $423.8 million. Management reaffirmed standalone 2026 EPS guidance of $3.68–$3.83 but said results are biased toward the lower half, citing low Pacific Northwest power prices and a $6.1 million quarterly net loss tied to incremental Colstrip interests. The company plans a Montana rate review by year-end to seek recovery of the Avista Colstrip costs and expects a final state order on its pending Black Hills merger by Nov. 12, targeting year-end completion.

Analysis

The key issue is a mismatch between when NorthWestern bears costs and when regulators may permit recovery. Low wholesale prices now penalize its longer generation position; a rate-case filing is not recovery, and an adverse or delayed Montana process could extend the earnings drag into 2027. The related PCCAM decision also matters more after the portfolio shifted from short to long: ending sharing would reduce one source of downside, while restoring it could blunt upside when market prices improve.

Near term, the Montana merger order is a binary catalyst for both NWE and BKH. Approval may remove deal uncertainty, but should not be treated as immediate earnings accretion: management says merger savings ultimately benefit customers through future rate reviews. If approval is delayed or conditioned, closing and combined-company guidance move out, prolonging uncertainty. Verify the written order and merger consideration before attempting a merger-arbitrage position.

Over 1–3 months, the Montana cost-recovery path and PCCAM decision are more important to NWE earnings quality than headline data-center queue growth. Early-stage requests can trigger planning and investment before contracted load arrives; tariff approval, signed ESAs, customer deposits, and cost-allocation protections are the conversion tests. Over 6–18 months, transmission and generation investment can expand rate base, but also raises financing and regulatory-lag exposure. The contrarian point: projected large-load upside is being discussed before firm contracts and approvals; conversely, the current Colstrip drag may prove temporary if cost recovery is granted and market prices normalize. No standalone thesis on AVA follows from the disclosed transaction context.

Key Decisions for Investors

• Tactically underweight NWE versus a broad utility proxy such as XLU through the Montana order: the near-term earnings/recovery uncertainty is asymmetric. Reassess on an unconditional approval and credible cost-recovery timetable; reduce the underweight if the order is delayed or imposes material conditions.
• Do not price data-center requests as committed growth. Treat signed ESAs, tariff approval, customer funding, and stated in-service dates as required evidence before adding to a load-growth thesis; a further development-agreement termination would reinforce the caution.
• Monitor the Montana rate-case filing and PCCAM ruling as 1–3 month catalysts. The thesis improves if recovery is authorized and sharing ends; it is falsified by a delayed or adverse order, continued unrecovered Colstrip costs, or guidance pressure beyond the lower-half bias.
• Avoid a NWE/BKH merger-arbitrage trade until the exchange terms, current deal spread, and conditions in the final Montana order are verified; the call alone does not establish a favorable payoff.
