1 Fellow Shareholders, July 31, 2025 The company made progress in Q2 on all fronts: We launched our AI-1TM product platform, hit key milestones with strategic customers, and launched a warrant dividend to simultaneously reward our shareholders and fund our growth. Fab2 in Malaysia has manufactured its first AI-1 batteries on our high-volume manufacturing (HVM) equipment. With our products sampling to two major smartphone OEMs, a leading smart eyewear company and four additional strategic IoT customers, we are truly moving into our commercial phase. Highlights Revenue growth and margin expansion: We delivered Q2 revenue of $7.5 million—above our guidance range and up 98% year-over-year—driven by strong demand for our products. Our non-GAAP gross margin reached 31%, reflecting the higher margin of our defense product sales from our Korean facility, whose potential is exceeding our expectations in the post-tariff world. AI-1 Platform Launch: We launched the AI-1TM platform, a core battery architecture, which employs advanced materials, micron-level design rules, and fully automated manufacturing processes that can be adapted rapidly into multiple product variants to serve different customers and end markets. As the leading AI-1 product, we produced the first smartphone battery achieving energy density of more than 900 Wh/L that simultaneously meets all the demanding cell phone customer requirements, including fast charging at 3C rates and a projected cycle life of 1,000-cycles based upon tests in our Malaysian factory. AI-1 Cell Phone Lead Products: We delivered samples of AI-1 smartphone batteries to our lead OEM customer to support their formal product qualification. Upon successful completion, we expect initial purchase orders. In July, we also began shipping samples to our second top-tier smartphone OEM customer. The reception to the AI-1 launch has been highly encouraging, and we expect to begin sampling additional leading OEMs in the coming months. AI-1 in Smart Eyewear. Wearing an electronic device on your head requires that it has a physically small battery, but the AI requirements demand a lot of power—hence, high energy density in a small package. Our marquee customer bought increased quantities of AI-1 AR batteries in July and began validation testing after its initial safety testing was successfully completed. AI-1 in AI Processors: We also shipped samples of our AI-1 AR battery to the leading processor OEMs in the AI market. These engagements are central to our reference design strategy—to partner

2 with leading suppliers in an emerging space, establish Enovix AI-1 batteries as the baseline design for hardware platforms, and enable broader adoption across multiple OEMs. Industrial Handheld Devices Customer Agreement: We signed an agreement with a top-tier industrial handheld systems manufacturer to expand our business into adjacent market segments—such as logistics, retail, and field services—where tariff-safe, high-energy batteries have strong demand for design ins. Defense and industrial engagements continued to expand, particularly in Asia, where the Korean asset acquisition added important capacity and capabilities—at a bargain price. In the U.S., our team secured a second marquee defense customer for initial sampling of our Korean products. Manufacturing Readiness: Our team made strong progress in Q2 by accelerating customer qualification efforts and reducing custom product development timelines by approximately 50%. We also completed our UN38.3 (airline safety) certification for our first AI-1 smartphone battery, an important milestone required for mass shipments. To support anticipated demand growth, we have also begun procuring long-lead components for our second HVM line. (Video.) Warrant Dividend: In July, we issued a special shareholder warrant rewarding our shareholders while providing the company with the opportunity to raise up to $255 million in additional capital. The Battery is Becoming the Bottleneck. The AI-1 platform launch is a major corporate milestone, marking our progression from innovation to commercialization. Today’s next-generation smartphones require both significantly higher energy storage and power capacity to perform AI functions locally—and battery performance is becoming critical in the era of the 100-billion-plus transistor AI chip. AI-1™ is our Artificial Intelligence Class™ battery platform, a core battery architecture, defined by advanced materials, micron-level design rules, and a fully automated manufacturing processes that can be adapted into multiple product variants to serve different customers and end markets. From this platform, we are able to deliver market and customer-specific products optimized for different target markets such as smartphones, IoT and computing devices. Recently, smartphone OEMs are realizing the growing mismatch between what today’s batteries can deliver and what next-generation, AI-enabled devices require—especially in terms of energy density, fast charging, and form factor. As a result, we are seeing smartphone OEMs increasing the importance placed on batteries in their products. Battery cost as a percentage of the bill of materials is rising as OEMs increase battery capacity to meet AI demands.

3 We recently witnessed the introduction into the market of an 8,300mAh+ smartphone battery in a $200 to $300 smartphone. The previous year’s model was 6,600mAH—a 25% increase in capacity. In the coming years, we believe battery capacities will grow to over 10,000mAh while maintaining similar physical dimensions—driving demand for higher energy density. With our leadership in energy density—and new manufacturing plant that can deliver it in volume, we believe AI-1 is arriving at the right time to break this bottleneck. Korea. We began integrating the manufacturing assets acquired in Q2’25. We are pleased with the speed of integration and the ability of the newly acquired coating equipment to support the Fab2 ramp internally with production anode and cathode roll product—105mm-wide, 500-meter-long sheets of copper and aluminum foil with our latest anode (silicon) and cathode (cobalt oxide) materials applied to them in precise thickness. This strategic new anode and cathode capability will enhance battery performance, reduce cost and enable us to prototype new materials in 7 weeks instead of 20 weeks. Financials are improving and beat street estimates for the fifth consecutive quarter.

Non-GAAP Financial Measures This shareholder letter includes the use of non-GAAP financial measures, which are intended to provide supplemental information regarding our performance. These non-GAAP measures include non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP gross margin, non-GAAP research and development expense, non-GAAP selling, general and administrative expense, non-GAAP operating expenses, non- GAAP operating income (loss), EBITDA, adjusted EBITDA, non-GAAP net income (loss) attributable to Enovix shareholders, non-GAAP earnings (loss) per share, free cash flow, and other non-GAAP measures. We use these non-GAAP measures to supplement our financial reporting and to evaluate ongoing operations and results, facilitate internal planning and forecasting, and assess performance against prior periods, industry peers, and the broader market. These non-GAAP measures are not prepared in accordance with generally accepted accounting principles (GAAP) and should not be considered as an alternative to GAAP results. Industry peers and other companies may calculate similar non-GAAP measures differently. Non-GAAP financial measures have limitations, including but not limited to, that they exclude certain expenses that are required under GAAP, which adjustments reflect the exercise of judgment by management. We believe that these non-GAAP measures, when considered together with the GAAP results, provide investors with an additional understanding of our operating performance. Reconciliations of each non-GAAP financial measure to the most directly comparable GAAP financial measure can be found in the tables at the end of this shareholder letter. While Enovix provides third quarter 2025 guidance for non-GAAP operating loss, adjusted EBITDA loss and non-GAAP net loss per share attributable to Enovix, we are unable to provide without unreasonable effort a GAAP to non-GAAP reconciliation of these projected non-GAAP measures, and we have not provided a quantitative reconciliation in reliance on the unreasonable efforts exception under Item 10(e)(1)(i)(B) of Regulation S-K. Such reconciliation to the corresponding GAAP financial measure cannot be provided without unreasonable effort because of the inherent difficulty in accurately forecasting the occurrence and financial impact of the various adjustments that have not yet occurred, are out of our control, or cannot be reasonably predicted, including but not limited to change in fair value of common stock, stock-based compensation and related tax effects, acquisition-related costs, and restructuring costs. As a result, we are unable to assess the probable significance of the unavailable information, which could have a material impact on our future GAAP financial results.
