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.

4 Revenue for the second quarter of 2025 was $7.5 million, above our guidance range of $4.5 million to $6.5 million and nearly double the second quarter of 2024, driven by broad customer demand. GAAP gross profit was $1.9 million (26% GM) GAAP and non-GAAP gross profit was $2.3 million (31% GM), marking our third consecutive quarter of positive gross margin. The improvement was driven primarily by a favorable mix of higher-margin, Korean-built defense products. The Q2’25 results compare favorably to Q2’24 GAAP gross loss of $0.7 million and a non-GAAP gross loss of $0.6 million. Adjusted EBITDA Loss narrowed to $20.1 million, ahead of our guidance range of $23 million to $29 million, and improved from $25.9 million in the same period a year ago. GAAP Q2’25 net loss per share attributable to Enovix was $0.22 and non-GAAP net loss per share was $0.13, better than our guidance range of $0.15 to $0.21 per share, and better than the Q2’24 results of $0.63 on a GAAP basis, and $0.13 on a non-GAAP basis. As required by ASC 260, Earnings Per Share, the share and per share amounts in the condensed consolidated financial statements for the periods presented above have been retroactively adjusted to reflect the July warrant dividend. Cash, cash equivalents, and short-term investments at the end of Q2’25 were $203.4 million, after completing the Korean asset acquisition and capital expenditure payments related to Fab2. Share Repurchase Program. In July, our Board authorized a share repurchase program of up to $60 million, providing us with the ability to opportunistically repurchase stock in the open market. The program is intended to defend shareholder value during a period of elevated market volatility. As of July 30, no repurchases had been made under the program. A full reconciliation of our GAAP to non-GAAP results is available later in this report. Q3’25 Financial Outlook • Revenue of $7.5 million to $8.5 million, up from Q2’25: $7.5 million and Q3’24: $4.3 million • Non-GAAP operating loss of $31 million to $35 million (Q2’25: $26.5 million, Q3’24: $26.9 million) • Non-GAAP net loss per share in the range of $0.14 to $0.18 (Q2’25: $0.13, Q3’24: $0.16)

5 In the second quarter of 2025, Enovix delivered on key milestones in product development, manufacturing readiness, and commercialization. We finalized the AI-1 battery platform, shipped production samples for product qualification, exceeded revenue expectations, and achieved our third straight quarter of positive gross margin. With AI-1 launched, mass production advancing, and new customers entering qualification, we are moving into the commercialization phase. Thank you for your continued support. ____________________________ _____________________________ Raj Talluri Ryan Benton

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.

12 Net Loss Attributable to Enovix to Adjusted EBITDA Reconciliation While we prepare our consolidated financial statements in accordance with GAAP, we also utilize and present certain financial measures that are not based on GAAP. We refer to these financial measures as “non-GAAP” financial measures. In addition to our financial results determined in accordance with GAAP, we believe that EBITDA and Adjusted EBITDA are useful measures in evaluating its financial and operational performance distinct and apart from financing costs, certain non-cash expenses and non-operational expenses. These non-GAAP financial measures should be considered in addition to results prepared in accordance with GAAP but should not be considered a substitute for or superior to GAAP. We endeavor to compensate for the limitation of the non-GAAP financial measures presented by also providing the most directly comparable GAAP measures. We use non-GAAP financial information to evaluate our ongoing operations and for internal planning, budgeting and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors in assessing its operating performance and comparing its performance with competitors and other comparable companies. You should review the reconciliations below, but not rely on any single financial measure to evaluate our business. “EBITDA” is defined as earnings (net loss) attributable to Enovix adjusted for interest expense, income tax benefit, depreciation and amortization expense. “Adjusted EBITDA” includes additional adjustments to EBITDA such as stock-based compensation expense, change in fair value of common stock warrants, inventory step-up, impairment of equipment, certain legal costs related to our defense of an ongoing securities class action complaint that is outside the ordinary course of business and that we do not consider representative of our performance, and other special items as determined by management which it does not believe to be indicative of underlying business trends. These non-GAAP measures may differ from similarly titled measures used by other companies.

15 of 18 Free Cash Flow Reconciliation We define Free Cash Flow as net cash used in operating activities less capital expenditures, net of proceeds from disposals of property and equipment, each as reported in our consolidated statements of cash flows. Free Cash Flow is a non-GAAP financial measure and should not be considered an alternative to cash flows from operating activities as determined in accordance with GAAP. We believe Free Cash Flow is a useful measure for investors because it provides insight into the cash generated or used by our operations after funding capital expenditures, and it helps assess our ability to pursue strategic growth initiatives. We use Free Cash Flow internally to evaluate performance, support decision-making, and measure our progress toward profitability and cash flow breakeven. This non-GAAP measure may differ from similarly titled measures used by other companies. Below is a reconciliation of net cash used in operating activities to the Free Cash Flow financial measure for the periods presented (unaudited) (in thousands): Fiscal Years-to-Date Ended June 29, 2025 June 30, 2024 Net cash used in operating activities $ (42,766) $ (61,993) Capital expenditures (14,243) (40,297) Acquisition of assets (10,000) — Free Cash Flow $ (67,009) $ (102,290)
