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

Overview

The report assesses JX Advanced Metals' planned joint feasibility study with Tronox for rare-earth refining. Goldman Sachs views the near-term earnings effect as limited but considers the project strategically aligned with JX's advanced-materials expansion, supply-security needs and potential longer-term entry into critical minerals.

Core views

JX Advanced Metals announced on September 29 that it will begin a joint study with U.S.-based chemicals producer Tronox Holdings in October 2026, targeted for completion during 2027. The study will examine rare-earth concentrate processing, leaching, separation and refining, with Australia and the United States under consideration. Total study cost is expected to be about US$32 million, or roughly ¥5 billion, split equally between the companies. They are evaluating potential capacity of up to 10,000 tonnes annually on a rare-earth-oxide-equivalent basis. JX says the effect on FY3/27 consolidated earnings will be limited, so Goldman Sachs frames the announcement primarily as a longer-term strategic development rather than a near-term earnings catalyst. The report argues that the collaboration fits JX's existing technical base. JX brings purification and refining technology developed through copper and rare-metal smelting and recycling, while Tronox contributes access to raw materials as well as mining and mineral-separation expertise. Goldman Sachs believes this combination could create complementary capabilities through the value chain and that JX's smelting, refining and high-purity processing skills can extend to rare-earth refining. The study covers lanthanum, used in optical glass, lenses and dielectric materials including MLCCs; yttrium, used in electronic materials including MLCCs; and neodymium, a key input for high-performance permanent magnets and also used in capacitors and ceramic electronic components. Goldman Sachs views the initiative positively because rare-earth supply chains are highly concentrated in mainland China across mining, refining and separation. The report links the project to increasingly stringent Chinese export controls and rising global demand to diversify supply chains. In JX's 2040 Long-Term Vision, semiconductor materials and information-and-communications materials are core growth businesses; the institution therefore sees upstream rare-earth capability as a way to reinforce raw-material procurement for these businesses. Over time, commercialization could also create a new earnings pillar in critical minerals. The supply-security argument is reinforced by JX's recently announced capacity investments. FY3/27 guidance includes ¥135 billion of total capital expenditure as of 1Q FY3/27. 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, with ramp-up from 2H FY3/27. InP-substrate capacity at Isohara and Hitachinaka is planned at seven to ten times FY3/26 levels, also beginning ramp-up in 2H FY3/27, while tantalum-powder capacity in Thailand is planned at 1.5 times FY3/26 levels from 1H 2027. Goldman Sachs sees the rare-earth study as a proactive upstream response alongside these downstream advanced-materials expansions. Goldman Sachs is Buy rated on JX Advanced Metals with a 12-month target price of ¥5,160, versus a ¥3,492 price as of the September 29, 2026 close, implying 47.8% upside. Its target-price framework uses the materials-sector EV/GCI 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 starts with the announced study's scope, timing, cost and prospective capacity, then assesses how JX's refining expertise and Tronox's mining and separation capabilities fit together. It connects the partnership to concentrated rare-earth supply chains, JX's advanced-materials growth strategy and planned capacity additions, before applying its stated valuation framework to the 12-month target price.
