Starboard pressure turned Algonquin Power into a pure-play regulated utility

Starboard disclosed a stake in Algonquin Power & Utilities in June 2023—about 7.5% economic exposure including swaps—arguing the shares were undervalued; the utility-plus-renewables blend had lost investor favor and the stock had plunged.

Already reviewing its renewable group since May 2023, Algonquin announced in August 2023 that it would abandon non-regulated renewables and its CEO departed. In March 2024 Starboard nominated directors; an April 2024 cooperation agreement added two board seats and a standstill, with the new directors given access to the renewables-sale and CEO-search processes.

In August 2024 Algonquin agreed to sell its renewable energy business (excluding hydro) to LS Power for up to $2.5 billion—$2.28 billion in cash plus earn-out—and completed the sale in January 2025, alongside selling its 42.2% Atlantica stake in December 2024.

Renewables (ex-hydro) sold to LS Power for up to $2.5B; two Starboard-backed directors; AQN refocused as a pure-play regulated utility with debt paydown.

The 13D put a structural 'pure-play utility' thesis in writing before any deal.

Board seats let Starboard monitor the sale and CEO search from inside.

Divesting low-rated renewables simplified the balance sheet and financing.

A written thesis about a structural discount can outlast the first refusal; Starboard's board seats kept the divestiture process on the agenda until it closed.

AQN used the proceeds to repay debt and sharpen focus on its regulated utilities, completing the transformation the activist thesis had called for; the company continued to trade as a regulated utility pure play on the TSX and NYSE.
