JX Advanced Metals Corp. (5016): Goldman Sachs sees JX's rare-earth study with Tronox as a strategically positive route to stronger supply security

Overview

The report assesses JX Advanced Metals' proposed joint rare-earth refining study with Tronox Holdings. Goldman Sachs considers the initiative strategically aligned with JX's advanced-materials expansion and potentially valuable for long-term supply security, while noting that FY3/27 earnings impact is expected to be limited.

Core views

JX Advanced Metals announced on 29 September that it will launch a joint study with U.S.-based chemicals producer Tronox Holdings to assess entry into rare-earth refining. The work is expected to start in October 2026 and be completed during 2027. It will examine rare-earth concentrate processing, leaching, separation and refining, with Australia and the United States among the potential locations. The total study cost is expected to be about US$32 million, or roughly ¥5 billion, split equally between the two companies; they are evaluating potential production capacity of up to 10,000 tonnes per year on a rare-earth-oxide-equivalent basis. The report emphasizes that the announcement is only a feasibility study and that JX expects limited impact on FY3/27 consolidated earnings. Goldman Sachs nevertheless views it positively as an upstream raw-material-security initiative after JX's recent capacity-expansion investments in its focus businesses. The potential strategic benefit is a more stable supply of inputs for semiconductor materials and information-and-communications materials, which JX identifies as core growth businesses in its 2040 Long-Term Vision. Over time, Goldman Sachs believes a commercial rare-earth-refining operation could also become a new earnings pillar in critical minerals. The investment case rests on complementary capabilities. JX brings purification and refining technologies developed through copper and rare-metal smelting and recycling, which Goldman Sachs believes can be extended to rare-earth refining. Tronox contributes access to raw materials as well as mining and mineral-separation expertise. The report argues that combining mining and separation with high-purity refining could create capabilities across the full value chain. The strategic backdrop is concentrated rare-earth supply chains, including mining, refining and separation in mainland China. Goldman Sachs interprets the initiative as a response to more stringent Chinese export controls and increasing global demand to diversify supply chains. The targeted elements have direct electronic-material relevance: lanthanum is used in optical glass, lenses and dielectric materials for MLCCs; yttrium is used in electronic materials including MLCCs; and neodymium is a key input for high-performance permanent magnets as well as capacitors and ceramic electronic components. The report places the initiative alongside JX's ongoing capacity expansion. Semiconductor sputtering-target capacity at Hitachinaka is planned to reach 1.3 times FY3/26 levels, with phased ramp-up from FY3/28. Magnetic-material sputtering-target capacity at Isohara is planned at 1.5 times FY3/26 levels from 2HFY3/27; InP-substrate capacity at Isohara and Hitachinaka is planned at 7-10 times FY3/26 levels from 2HFY3/27; and tantalum-powder capacity in Thailand is planned at 1.5 times FY3/26 levels from 1H 2027. JX's FY3/27 guidance assumed ¥135 billion of total capital expenditure as of 1QFY3/27. Goldman Sachs is Buy rated on JX Advanced Metals with a 12-month target price of ¥5,160. Its target-price methodology 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 sets out the scope, timing, cost and prospective capacity of the JX-Tronox feasibility study. It then assesses how the companies' respective mining, separation, refining and purification capabilities could fit together, links the project to concentrated rare-earth supply chains and JX's growth businesses, and places it alongside JX's announced capacity expansions. The report values JX using a materials-sector EV/GCI and FY3/28E CROCI/WACC approach.

Methodology notes

• Competition & strategyValue chain analysis

  Rare-earth value-chain complementarity

  The report evaluates how Tronox's raw-material access, mining and mineral separation combine with JX's high-purity refining and purification capabilities across the rare-earth value chain.

• Valuation methods

  Materials-sector EV/GCI and FY3/28E CROCI/WACC valuation

  Goldman Sachs derives its target price from a materials-sector EV/GCI framework and a FY3/28E CROCI/WACC multiple, then adds JX's recent historical premium to the sector average.

Impact & implications

Goldman Sachs argues that the partnership could improve long-term input security for JX's semiconductor and information-and-communications materials businesses while positioning the company for a potential future critical-minerals earnings stream. The immediate financial effect is expected to be limited because the initiative remains at the feasibility-study stage.

Risks

• A slowdown in semiconductor demand could weaken JX's focus businesses.
• A slowdown in AI-server demand is a stated risk.
• Delays in structural reforms are a stated risk.
• Yen appreciation could be adverse.
• Copper and other metal-price fluctuations could affect results.

What to watch

• Progress of the joint study from its October 2026 start toward targeted completion in 2027.
• Whether feasibility work supports commercialization of a rare-earth-refining operation.
• Development of stable raw-material supply for semiconductor and information-and-communications materials.
