The Market

The Graphite Problem: A Threat to U.S. National Security Chinese Dominance China is the world’s largest producer and exporter of graphite with ~95% imported from China.1 On December 1, 2023, China imposed export controls on certain graphite items and further tightened these controls in December 20242 and again in October 2025. These controls have since been suspended until November 2026. Synthetic graphite is on the U.S. Geological Survey’s Critical Minerals List—underscoring its economic and national security importance. An enormous risk to US energy security and defense.

NOVONIX Riverside: First Mass Production Facility for Synthetic Graphite NOVONIX Riverside Purchased and opened Riverside facility in 2021, highlighted by a grand opening attended by US Secretary of Energy Facility to scale to 20k tpa aligned with customer demand First mass production delivery to industrial customer October 2025 Awarded $100M DoE MESC grant Allocated up to $103M 48C investment tax Credit First-Mover Advantage No other company in North America has manufactured and shipped synthetic graphite on a mass scale to an OEM or battery manufacturer.

NOVONIX Enterprise South: Our Next Phase of Growth NOVONIX Enterprise South NOVONIX Enterprise South is expected to have full production capacity of 31.5k tpa This facility, together with NOVONIX’s existing 20k tpa Riverside facility in Chattanooga, will bring the Company’s total production capacity to over 50k tpa Offered Conditional Commitment for a US$754 Million Loan from the U.S. Department of Energy Eligible for potential tax credits under the Advanced Manufacturing Production Tax Credit (Section 45X) Received tax benefits from Chattanooga and Hamilton County of ~$54M Site Rendering Proposed NOVONIX Enterprise South rendering located on 182 acres in the Enterprise South Industrial Park in Chattanooga, Tennessee. In March 2025, NOVONIX received unanimous approval from both the City of Chattanooga and Hamilton County for the land purchase. Enterprise South will be acquired for approximately US$5 million. The Company also received an estimated US$54 million in net tax and other benefits to be realized over a 15-year period, subject to the satisfaction of conditions.

NVX will add production lines at facilities to generally align with contracted volumes The volumes shown are management’s annual estimates of the offtakes for PowerCo and Panasonic * Agreements require final product qualification.

Typical Material Qualification Process Qualification is a partnership between NOVONIX and its customers. For battery grade synthetic graphite, qualification is rigorous and timelines can vary depending on a customer’s specifications and qualification processes. In 2025, the Company supplied advanced samples of synthetic graphite material to 15 different customers and potential customers for their battery, energy storage, and industrial applications. This included samples for Panasonic and PowerCo. 12 POTENTIAL CUSTOMERS INDUSTRIAL CUSTOMER Pre-A Samples A Sample B Sample C Sample SOP Volumes Initial sample for physical and basic electrochemical performance Less than 1kg Feedback in less than 2 months Iteration to requirements evaluated on cell maker pilot line 1-5kg sample Feedback in less than 2 months Validation of design performance and processibility on mass production equipment 50 – 10,000 kg sample Feedback typically in 6 months Validation of production design on production equipment Mass Production Scale 5,000 kg – 30,000 kg (5-30 tonne) sample Feedback 6 - 12 months Confirmation of quality control All productions audits must be passed Contracted volumes ramp to meet customer requirements

Customer Diversification Synthetic Graphite for Industrial Applications In September, NOVONIX announced the delivery of its first mass production, commercial-grade sample of synthetic graphite for industrial applications. Customer: one of North America’s largest value-added carbon processors with a global market reach. The ability to provide volumes to markets outside the battery space diversifies our product portfolio and provides the opportunity to increase our planned production at Riverside for 2026. Industrial-grade product qualification is fast and flexible and enables a faster path to market than battery-grade synthetic graphite. Any target supply volumes will be further defined once final product qualification has been completed and a definitive supply agreement has been established.

Strategic Partnership with Phillips 66 NOVONIX uses petroleum coke, a byproduct of U.S. oil refining, as feedstock for our synthetic graphite products, ensuring a stable, domestic raw material supply chain while reducing waste. In 2017, NOVONIX began testing P66 petroleum coke as feedstock for battery-grade synthetic graphite anode materials. In September 2021, P66 invested $150 million for a ~15% ownership stake in NOVONIX to align with the battery value chain. Along with the initial investment, P66 received a seat on our Board of Directors. In January 2022, NOVONIX and P66 agreed to a Technology Development Agreement to identify improved feedstocks in current or future P66 product portfolios. In January 2025, P66 participated in our follow-on equity offering, investing an additional $5 million. Lake Charles, LA, P66 refining facility

Looking Forward

Key Highlights Driving Future Growth Scaling Riverside Operations to Deliver Production Volumes Securing Financing to Further Scale Operations Continuing to Secure Tier 1 Customers Completed installation and commissioning of all required mass production equipment for our lead battery grade customer, Panasonic. Leverage Riverside engineering to progress our further phases of expansion (Enterprise South). Funding agreement completed with Yorkville for US$100 Million of Convertible Debentures. Conditional Commitment for a US$754 Million Loan from the U.S. Department of Energy for a New Synthetic Graphite Manufacturing Plant in Tennessee, NOVONIX Enterprise South. Invest alongside US$100 Million MESC grant funds to scale Riverside production. Attract additional strategic investment to continue the production build out of Riverside and Enterprise South optimizing for flexibility of terms and cost of capital.
