Exhibit 99.1

Key Highlights

Strategic Partnerships and Financing Engagement

In September, NOVONIX announced that the first phase of the NOVONIX synthetic graphite AAM project had been included in a South Korea–U.S. infrastructure initiative coordinated by the Republic of Korea’s Ministry of Land, Infrastructure and Transport and Korea Overseas Infrastructure & Urban Development Corporation (KIND). The initiative facilitates introductions to Korean contractors, strategic partners, and potential financing sources.

NOVONIX also announced a non-binding memorandum of understanding with ACP Technologies to evaluate domestic carbon precursor materials and pitch-coated synthetic graphite AAM.

Proposed work includes product development, process validation, and potential customer sampling. Any commercial arrangements remain subject to further agreement.

Commercial Operations and Customer Qualification

During the quarter, NOVONIX continued its qualification work for synthetic graphite anode active material produced at its Riverside facility in Chattanooga, Tennessee. As disclosed in September, the initial C-sample met most specification parameters, leaving several outstanding. NOVONIX has identified targeted actions and is undertaking further work to address the remaining parameters in coordination with the customer’s final acceptance. It is expected that all outstanding work will be completed in the near future. Successful qualification remains subject to further customer testing and approval. The Company’s previously communicated expectation for commencement of mass production sales in the second half of 2027 remains subject to successful completion of the applicable qualification process and other operational and commercial conditions.

Industry and Sector Outlook

Graphite AAM is a critical input to lithium-ion batteries used in stationary energy storage, defense applications, and electric vehicles. Demand for battery energy storage in the United States continues to grow, supported by increasing electricity demand, grid reliability requirements, and the expansion of energy storage infrastructure.

According to the U.S. Energy Information Administration (EIA), U.S. utility-scale battery storage capacity reached approximately 52 gigawatts (GW) by June 2026, with developers planning to add approximately 54 GW of additional capacity through 2028.1 This growth represents an expanding potential domestic market for battery materials, including synthetic graphite AAM.

Industry outlooks are consistent with the EIA data. A September 2026 report by the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence revised its forecast for cumulative U.S. energy storage capacity through 2030 upward by 11.5% to 683 GWh,2 reflecting stronger-than-expected demand. The report also noted that U.S. energy storage installations reached a record 20.2GWh in the second quarter of 2026.

U.S. Government Policy Developments

National Security Focus

U.S. government policy continues to emphasize the importance of secure domestic critical mineral and battery supply chains. During the quarter, the U.S. Government continued to advance

policies aimed at strengthening domestic critical minerals and battery materials supply chains and reducing reliance on foreign-controlled sources. On July 20, 2026, the President issued an Executive Order, Securing America's Defense Supply Chains and Ensuring Domestic Acquisition of Critical Materials, establishing a policy of sourcing critical materials and components for military equipment domestically or from allied nations. The Executive Order directs the Department of War to strengthen supply chain traceability, address reliance on unreliable foreign suppliers, and accelerate the qualification of alternative sources of critical materials and components.

These initiatives complement existing measures that, beginning on October 1, 2027, prohibit the Department of War from procuring batteries produced by six specified Chinese manufacturers, including Contemporary Amperex Technology Co., Limited (CATL) and BYD Company Limited (BYD), subject to waiver by the Secretary of War. The restrictions also apply to batteries that have a majority of components from those manufacturers and batteries manufactured or assembled by those entities.

Beginning in January 2028, these restrictions will expand to prohibit, in a phased manner, the use of battery materials sourced from foreign entities of concern (FEOCs), such as China.

These prohibitions reflect the U.S. government's increasing focus on reducing reliance on Chinese-controlled battery supply chains for defense applications and reinforces the strategic importance of developing secure domestic sources of critical battery materials, including graphite AAM.

AD/CVD Appeal

The March 2026 determination by the U.S. International Trade Commission (ITC) that imports of graphite AAM from China did not materially retard the establishment of a domestic industry is under appeal before the U.S. Court of International Trade (CIT). Oral arguments are scheduled for the second half of January 2027.

If the CIT identifies legal errors or findings unsupported by substantial evidence, it will remand the determination to the ITC for reconsideration. On remand, the ITC would be required to address the issues identified by the CIT. The ITC could either reaffirm its original negative determination or reach a new affirmative determination. An affirmative determination would result in the imposition of antidumping and countervailing duties on Chinese graphite AAM at the rates previously determined by the U.S. Department of Commerce, which were approximately 160%.

ITC reversals are unusual. However, of the three commissioners who issued the original decision against the domestic industry, in March 2026, only one (who voted in favor of the domestic industry and imposing the tariffs) remains on the ITC. There are now five new commissioners on the ITC. With a full slate of six commissioners, only three commissioners need to vote in favor of the domestic industry to have the tariffs imposed.

On October 19, 2026, the petitioners in the appeal requested that the ITC request a voluntary remand of their March 2026 negative injury determination. It would be unusual for the ITC to request such a voluntary remand. However, if they do so, and if the CIT grants such request, the review of the appeal would be expedited.

Funding and Financial Overview

Cash Balance

The Company’s cash balance as of 30 September 2026 was US$33.652 million.

Payments to Related Parties

A total of US$339,000 was paid to Directors and their associates for salary and wages, director fees, and superannuation during the quarter ended 30 September 2026.

Capital Expenditures

The Company invested US$8.36 million in property, plant, and equipment during the quarter ended 30 September 2026, primarily for production assets at its Riverside facility in Chattanooga, Tennessee.

The Company continues to assess capital requirements and funding alternatives to support production readiness and future capacity. Funding remains subject to applicable conditions, commercial agreements, and capital-market and government-program availability. In September, the Company disclosed an amortisation event under its Yorkville convertible debenture arrangement arising from the share-price condition. As required under that arrangement, a US$7 million repayment occurred from cash reserves in each of September and October.

Events Subsequent to Quarter End

ISO 9001 Certification

In October 2026, NOVONIX announced that its Riverside facility in Chattanooga, Tennessee, achieved ISO 9001:2015 certification, an internationally recognized standard for quality management systems. The certification follows an independent assessment of the facility's quality management processes and demonstrates that NOVONIX has established systems designed to support consistent product quality, process control, traceability, continuous improvement, and customer satisfaction.

Achieving ISO 9001 certification represents an important milestone in NOVONIX's progression toward commercial-scale production of synthetic graphite anode active material. The certification strengthens the Company's quality management infrastructure and supports its ability to meet the rigorous requirements of automotive battery manufacturers and other customers. It also represents an important step in NOVONIX's broader commercialization

strategy as the Company advances customer qualification activities and prepares for future production at Riverside.

The certification does not itself constitute customer product qualification, which remains subject to each customer's applicable testing and approval requirements.

PowerCo Supply Agreement

In October 2026, NOVONIX and PowerCo SE entered into an Amended and Restated Supply Framework Agreement, replacing the previous binding offtake agreement. The revised agreement reflects evolving market conditions and PowerCo's updated production plans for its battery manufacturing facility in St. Thomas, Ontario, where commencement of production has been deferred from 2027 to 2029. Under the revised framework, the parties have removed the previous volume, pricing, and delivery commitments and intend to negotiate new commercial terms following completion of PowerCo's qualification process and required certifications. The agreement maintains the parties' commercial relationship while providing flexibility to align future supply arrangements with PowerCo's revised production schedule and market demand.

Outlook

In the near term, the Company's priorities remain focused on advancing customer qualification and developing synthetic graphite AAM to address evolving customer requirements across the energy storage systems (ESS) and electric vehicle markets. Building on the momentum of its recent ISO 9001 certification, the Company continues to advance facility readiness, strengthen quality systems, and refine manufacturing operations to support consistent product deliveries at commercial scale. Alongside these operational priorities, cost discipline and strategic financing remain central to the Company's financial strategy, with continued efforts to optimize operating expenses and engagement with institutional investors and strategic financing partners to strengthen its balance sheet and support its next stage of commercial growth. The Company also continues to engage with the U.S. Government on policy initiatives aimed at strengthening the domestic AAM industry and supporting a competitive environment for U.S.-based synthetic graphite AAM production.
