JX Advanced Metals Corp. (5016): Goldman Sachs sees strategic long-term value in JX Advanced Metals' rare-earth study with Tronox

Overview

The report examines JX Advanced Metals' planned joint study with Tronox Holdings into rare-earth refining. Goldman Sachs considers the project strategically positive because it could strengthen raw-material security for JX's advanced-materials businesses and potentially create a longer-term critical-minerals earnings opportunity.

Core views

JX Advanced Metals announced on 29 September that it will begin a joint study with U.S.-based chemicals producer Tronox Holdings in October 2026 to assess entry into rare-earth refining. The work will cover rare-earth concentrate processing, leaching, separation and refining, with Australia and the United States among the potential locations; completion is targeted during 2027. The companies estimate total study costs of roughly US$32 million, or about ¥5 billion, split equally, and are evaluating potential production capacity of up to 10,000 tonnes a year on a rare-earth oxide-equivalent basis. JX has said the initiative should have limited impact on FY3/27 consolidated earnings. Goldman Sachs' central argument is that the study fits JX's existing capabilities and growth strategy. JX brings advanced smelting, refining and purification technology developed in copper and rare-metal refining and recycling. Tronox brings raw-material access, mining expertise and mineral-separation capabilities. The institution argues that these complementary roles could span the value chain from feedstock through high-purity refining, making a rare-earth operation strategically credible even though the current announcement is only a feasibility study. The report links this potential upstream move to supply-chain resilience. It notes that rare-earth supply chains are highly concentrated in mainland China across mining, refining and separation, and views the initiative as a response to tighter Chinese export controls and rising demand for globally diversified supply. Lanthanum and yttrium have applications in optical glass, lenses, dielectric materials and MLCC-related electronic materials, while neodymium is a key input for high-performance permanent magnets and is also used in capacitors and ceramic electronic components. Goldman Sachs therefore sees a potential benefit in securing supplies relevant to JX's semiconductor-materials and information-and-communications-materials businesses. The institution also places the project alongside JX's recent capacity investments. FY3/27 guidance assumes total capital expenditures of ¥135 billion as of 1Q FY3/27. Semiconductor sputtering-target capacity at Hitachinaka is planned to reach 1.3x FY3/26 levels, with phased ramp-up beginning in FY3/28; magnetic-material sputtering-target capacity at Isohara is planned at 1.5x, with ramp-up from 2H FY3/27. InP-substrate capacity at Isohara and Hitachinaka is planned at 7-10x FY3/26 levels, also beginning in 2H FY3/27, while tantalum-powder capacity at the Thailand plant is planned at 1.5x FY3/26 levels, with ramp-up from 1H 2027. In this context, Goldman Sachs views rare-earth refining as a proactive effort to underpin raw-material procurement for expanding focus businesses and, over time, as a possible new critical-minerals earnings pillar. Goldman Sachs remains Buy rated on JX Advanced Metals with a 12-month target price of ¥5,160, compared with a ¥3,492 closing price on 29 September 2026 and stated upside of 47.8%. Its target price uses the materials-sector EV/GCI framework and FY3/28E CROCI/WACC, applying a 0.7x CROCI multiple plus JX's recent historical 25% premium to the sector average.

Analysis framework

Goldman Sachs first assesses the terms and scope of the JX-Tronox feasibility study, then evaluates the fit between each party's operational capabilities. It connects the project to concentrated rare-earth supply chains, JX's raw-material needs and announced capacity additions before retaining its rating and target-price framework.

Impact & implications

Goldman Sachs views the study as a potentially important upstream procurement strategy for JX's expanding semiconductor and information-and-communications materials businesses. The near-term earnings effect is expected to be limited, but successful commercialization could diversify rare-earth supply and create a longer-term critical-minerals business.

Risks

• A slowdown in semiconductor demand could weaken JX's focus businesses.
• A slowdown in AI server demand could weigh on demand exposure.
• Delays in structural reforms could affect the investment case.
• Yen appreciation could be adverse.
• Fluctuations in copper and other metal prices could affect results.

What to watch

• Progress of the JX-Tronox study from its October 2026 start through targeted completion in 2027.
• Whether the partners advance from feasibility work to commercialization and confirm a location and capacity.
• Developments in rare-earth supply diversification and Chinese export controls.
• Execution of JX's announced semiconductor-material, magnetic-material, InP-substrate and tantalum-powder capacity expansions.
