Table of Contents Talent Our talent and culture are critical to our success. Our human capital management philosophy and objectives focus on creating a high-performance culture in which our employees deliver, succeed and lead. We achieve our objectives through various employee engagement and talent development efforts. Our employee engagement efforts include our quarterly all-employee town hall meetings, through which we aim to keep our employees well- informed and to increase transparency, and employee engagement surveys, through which we incorporate critical employee feedback into our culture, operations and strategic plans. We have established relationships with top universities worldwide, professional associations and industry groups to build a talent pipeline and established the Enphase Learning Academy to provide employees with on demand relevant technical and professional programs. We are committed to promoting and cultivating an inclusive and diverse culture that welcomes and celebrates everyone without bias. In addition, we look to actively engage within our communities to foster and attain social equity. We became a corporate sponsor of the non-profit Women in Cleantech and Sustainability and our Chief Executive Officer signed the CEO Action for Diversity & Inclusion pledge. This shows our commitment to advancing diversity and inclusion in the workplace. Compensation Philosophy Our compensation philosophy creates the framework for our rewards strategy. We have a pay-for- performance culture that ties compensation to the performance of the individual and our company. We provide competitive compensation programs that focus on the following five key elements: • Pay-for-performance: Reward and recognize leading contributors and high potential employees by paying market competitive total direct compensation, which includes base salary, quarterly bonus or commission, and stock-based compensation • External market-based research: Pay levels that are competitive with respect to the labor markets and industries in which we compete for talent • Internal equity: Maintaining internally consistent and non-discriminatory pay and pay practices • Fiscal responsibility: Providing programs in line with economic conditions and our company’s financial health • Legal compliance: Ensure the organization is legally compliant with employee compensation laws in all states and countries in which we operate Health and Wellness We invest in our employees through high-quality benefits and various health and wellness initiatives. Our benefits packages provide a balance of protection along with the flexibility to meet the individual needs of our employees. Our global work-from-home policy introduced in response to COVID-19 pandemic was modified to allow employees in certain countries and locations to work in a hybrid mode as business necessitates. Our focus remains on the safety of our employees and business partners, and we strive to protect the health and well-being of the communities in which we operate, in part, by providing technology to our employees, end-customers and business partners to help them do their best work while remote. We expect these business operating conditions will substantially remain in effect throughout 2024. We will continue to actively monitor the situation and we will make further changes to our business operations as may be permitted by federal, state, or local authorities and that we determine are in the best interests of our employees, end-customers, partners, suppliers and stockholders.
