Altus Power (AMPS) said Wednesday that its stockholders voted to approve the previously announced acquisition by TPG (TPG) through its TPG Rise Climate Transition Infrastructure strategy.

The deal values Altus Power at about $2.2 billion, including outstanding debt, the company said in February.

Under terms of the merger agreement, stockholders will receive $5 in cash per share, without interest and minus any applicable withholding taxes, the company said.

The transaction is expected to close on April 16.
