Unitil's Seasonal Q3 Loss Widens As Cost Growth Outpaces Rate Relief, Leaving Q4 To Carry Reaffirmed Guidance

Unitil Corporation reported an adjusted loss of $0.04 per share for the third quarter, compared with adjusted earnings of $0.03 a year earlier. That is a 233.3% year-over-year decline in earnings, even as revenue rose 8.3% to $109.5 million. On a GAAP basis, the net loss widened to $0.08 per share from $0.02. The difference reflects $0.8 million of transaction costs tied to the Bangor, Maine Natural and Aquarion acquisitions.

The third quarter is seasonally Unitil's weakest because gas heating demand is minimal, so a small loss is not alarming on its own. The problem is direction. Rate increases and acquisitions are expanding the top line, but costs grew faster than margin.

• **Margin:** Total adjusted gross margin rose $4.3 million to $64.0 million, helped by gas therm sales up 10.5% and electric kWh sales up 1.3%.
• **Operating costs:** O&M rose $4.9 million, D&A rose $2.6 million and net interest expense rose $2.1 million.
• **Legacy costs:** Excluding Maine Natural, the Aquarion companies and transaction costs, legacy O&M still increased $2.4 million in the quarter. That was most of the $3.8 million legacy increase for the full nine months.

That is the central tension. The rate-base growth story remains intact, but the quarter showed cost pressure and financing drag absorbing much of the incremental margin.

The year-to-date picture shows the deceleration more clearly. Nine-month adjusted EPS of $2.12 is up $0.09, or 4.4%, from $2.03. That compares with gains of $0.14 at both the first-quarter and first-half marks, which were growth rates near 7%-8%. Margin growth also slowed:

• Electric adjusted gross margin growth eased to 11.1% year-to-date from 14.8% at midyear.
• Gas adjusted gross margin growth slipped to 12.8% from 13.5%.

Meanwhile, nine-month O&M growth of $8.2 million compares with roughly $3.3 million at the half. In the second quarter, management had emphasized that legacy O&M was up only about 1%. That claim looks dated now.

Management reaffirmed 2026 EPS guidance of $3.20-$3.36 and its 5%-7% long-term growth target for the fourth consecutive call. The balance-sheet work is largely done:

• a $200 million private placement at a 5.76% weighted average rate;
• $27.3 million of at-the-market equity issued year-to-date;
• acquisition term loans fully repaid in October.

The acquisitions are now permanently financed, and S&P FFO-to-debt held near 17%.

Rate base is up 14.9% year over year. Management's five-year average rate base growth of 9.5% sits above its 6.5%-8.5% guide. Maine Natural is fully integrated, and Aquarion's New Hampshire water operations contributed $3.1 million of revenue in their first quarter. Rate cases supply the next leg of earnings:

• New Hampshire gas has $5.5 million of temporary rates in place and permanent rates expected April 1, 2027.
• The Maine gas case, seeking $10.4 million, is proceeding.

The risks are more about timing and execution than thesis. Hitting the $3.28 guidance midpoint requires roughly $1.16 in Q4, versus about $1.13 a year ago. That is achievable, but it leaves the full year dependent on winter weather and cost control. The Aquarion Massachusetts acquisition now hinges on a base rate case expected to be filed around mid-November, with a possible order in the second half of 2027. That pushes the Eversource purchase further out. Management's tone was also noticeably more muted. Second-quarter language about "outstanding performance" and fully earning authorized returns gave way to "disciplined execution." Commentary on gas conversions, which had cited a 50% rise in inquiries last quarter, disappeared. No analysts asked questions.

Investors have turned more skeptical. Earnings Whispers sentiment fell from -0.36 to -0.62, a meaningful move deeper into negative territory. The stock tells a different story. Shares have gained 7.1% since opening at $52.71 after the August report and closed at $56.44, about 7.6% above the 200-day moving average of $52.46. The price and AVWAP trend readings remain positive. That divergence matters. The market has rewarded the defensive, rate-base-driven profile, while investors weigh slowing earnings momentum and a back-end-loaded year. A stock trading above trend with souring sentiment leaves less cushion if Q4 falls short of the roughly $1.16 needed.

The bottom line is that Unitil delivered on the structural pieces: financing, integration, rate base growth and reaffirmed guidance. However, the quarter's earnings quality deteriorated as O&M, depreciation and interest costs outran margin growth. Bears have legitimate ammunition in the slowing year-to-date trend and the more cautious tone. Bulls can point to a rate-case pipeline that should restore momentum in 2027. Until Q4 shows the cost curve bending, the gap between rising shares and falling sentiment is the key tension to watch.
