WAUKESHA, Wis. – November 1, 2021 — Generac Holdings Inc. (NYSE: GNRC) (“Generac” or the “Company”), a leading global designer and manufacturer of energy technology solutions and other power products, today announced the signing of an agreement to acquire the shares of ecobee Inc. (“ecobee”), a leader in sustainable smart home solutions, in a transaction valued up to $770 million USD contingent on the achievement of certain performance targets.

A pioneer in the smart thermostat market, ecobee was founded in 2007 and is headquartered in Toronto, Canada. With a team of over 500 employees globally, ecobee currently offers several ENERGY STAR-certified thermostats and a suite of home monitoring products, all designed with a focus on conservation, convenience, peace of mind and comfort. ecobee’s smart thermostats intelligently optimize heating and cooling systems to deliver significant energy savings for homeowners. With over two million connected homes, ecobee customers in North America have saved more than 20 TWh of energy, which is the equivalent of saving enough energy to take all the homes in Los Angeles off the grid for an entire year.

“ecobee’s solutions are an important addition to Generac’s extensive residential energy technology portfolio,” said Aaron Jagdfeld, president and chief executive officer of Generac. “Residential HVAC systems represent the largest energy-consuming device in the home today and ecobee’s smart thermostats and sensors offer the most intelligent way to balance comfort with conservation. In addition, the ability to combine ecobee’s cutting-edge technologies with Generac’s power generation, energy storage and energy management devices will allow us to create a clean, efficient, and reliable home energy ecosystem that will not only save homeowners money, but also help grid operators meet the challenges of an electrical grid under enormous stress by providing solutions to better balance supply and demand.”

“Generac’s evolution into an energy technology solutions company creates many opportunities to integrate our ecobee products with their residential device offerings, enabling direct monitoring and control of a significant portion of the home’s electrical load,” said Stuart Lombard, founder and chief executive officer of ecobee. “We are excited to join the Generac team so together we can deliver a cleaner, more resilient and sustainable energy future for our customers and communities.”

At closing, Generac will pay $200 million USD in cash along with $450 million USD in GNRC common stock to the current equity holders of ecobee. Additionally, upon achievement of certain performance targets between closing and June 30, 2023, the sellers may receive up to $120 million USD in additional shares of GNRC common stock.

The acquisition is expected to close during the fourth quarter, subject to customary closing conditions, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act.

Forward-looking statements give Generac's current expectations and projections relating to the Company's financial condition, results of operations, plans, objectives, future performance and business.

Any such forward looking statements are not guarantees of performance or results, and involve risks, uncertainties (some of which are beyond the Company's control) and assumptions. Although Generac believes any forward-looking statements are based on reasonable assumptions, you should be aware that many factors could affect Generac's actual financial results and cause them to differ materially from those anticipated in any forward-looking statements, including:
