We expect utility rates to be on the rise around the world. While EVs appear out of favor today, we strongly believe that full home electrication is inevitable. Our strategy is to build best-in-class home energy systems to enable full home electrication while positively impacting climate change. Our home energy systems, comprising of IQ Microinverters, IQ Batteries, IQ Smart EV chargers, and software, have seen remarkable adoption, with over 73 million solar microinverters and 1.2 GWh of IQ Batteries shipped at the end of 2023 since our company’s inception. Approximately 4.0 million Enphase-based systems have been deployed in 1 more than 150 countries, preventing 56 million metric tons of carbon dioxide equivalent. We are laser focused on innovation, quality, and customer experience to make our systems provide high value to consumers at lower cost. I extend my sincere gratitude to our employees for their dedication and hard work, and our customers, partners, and shareholders for their continued support.
