Unitil closes on Aquarion NH, eyes Massachusetts—a quiet strategic pivot
A Utility in Transition
Unitil's second-quarter print was steady—adjusted EPS of $0.29, H1 EPS of $2.17, up 7%—but the real news was the closing of the “acquisition of the Aquarion Water Company of New Hampshire” — Tom Meissner, Chairman and Chief Executive Officer · 2026-08-04 on June 30. With a $55.8 million price tag, the deal marks Unitil's first foray into water distribution, adding 14,000 or so customers and a new line of business to a portfolio previously focused on gas and electric. Management expects the transaction to be New Hampshire Water Companies earnings-neutral in 2026 and accretive once new distribution rates take effect—a classic regulated-utility playbook.
The Maine and New Hampshire Rate cases are progressing as expected, with permanent rates slated for April 2027 in New Hampshire and a Maine filing seeking $10.4 million. The 5-year capital plan has been increased 24% to ~$1.2 billion, and first-quarter revenue rose 27% year over year to $217 million, a pace that underscores the expansion.
The Oil-to-Gas Tailwind Is Real
Unitil operates in Maine, where roughly two-thirds of homes heat with oil, propane, or kerosene—fuels far pricier than natural gas. That gap is driving a surge in conversions: “we've seen a 50% increase in customers calling to inquire about natural gas service” — Tom Meissner, Chairman and Chief Executive Officer · 2026-08-04 in the first half, with ~1,500 new customers under contract or in construction. This is a company-specific catalyst riding a commodity backdrop that shows no sign of fading. As the CEO put it,
The same dynamic was already being flagged on the prior call, when management noted the “cost of oil has increased dramatically for home heating” — Tom Meissner, Chairman and Chief Executive Officer · 2026-05-05 and that they enjoy almost a 2:1 price advantage. What's new is the measurable acceleration in customer inquiries, suggesting the driver is gaining traction rather than staying theoretical.
Water—A Strategic Bet with a Longer Fuse
The Aquarion deal is not just about adding assets; it's a strategic signal. Unitil has signed a non-binding LOI with Eversource to also buy the Massachusetts Aquarion company, subject to a pending rate case. When asked whether the drawn-out regulatory process had cooled their appetite for further M&A, the CEO replied, “I would say no. We're still interested in further expansion of our footprint to the extent that it fits within our existing business model.” — Tom Meissner, Chairman and Chief Executive Officer · 2026-08-04 That tone has been consistent: on the May call, management noted the Connecticut approval was a condition for the overall transaction and that they were “keenly watching what happens in Connecticut” — Daniel Hurstak, Senior Vice President, Chief Financial Officer and Treasurer · 2026-05-05. The NH close is a concrete step in a multi-jurisdiction expansion that could roughly double the water footprint.
Rate base growth already reflects the M&A: rate base growth averaged 9.5% over the past five years, above the long-term range of 6.5%–8.5%. Management is funding the plan with a mix of equity (ATM issuance) and long-term debt, and FFO/debt remains comfortable at 17.2%. The Aquarion acquisition is a genuine strategic pivot for a company that, until now, was a pure gas-and-electric play. With the Massachusetts transaction still in the works, the story has room to grow.
