ENEOS Holdings filed an amendment to its large shareholding report on JX Metals Corporation (TSE: 5016) with the Kanto Local Finance Bureau on July 15, 2026. The filing's stated reason was blunt: its holding ratio in JX Metals had fallen by more than a full percentage point, from 42.38% to 35.28%.
The mechanism was JX Metals' own tender offer for its shares, which ran from May 21 to June 17, 2026. ENEOS tendered 57,300,022 of its shares into that offer. Because the total shares tendered by all shareholders exceeded the number JX Metals had planned to buy, the purchase was scaled back on a pro-rata basis, and only 57,274,900 of ENEOS's shares were ultimately accepted, at ¥3,401 apiece. Settlement completed on July 9, 2026.

The evidence packet's own digest of the filing puts the total value of the disposal at approximately ¥194.8bn. ENEOS now holds 336,254,102 shares in JX Metals, against 953,183,210 shares outstanding, meaning it remains comfortably the issuer's largest shareholder even after the reduction.
This is not ENEOS's first sell-down. The filing traces back to JX Metals' listing on the Tokyo Stock Exchange in March 2025, when ENEOS sold roughly 465.16 million shares as part of the initial offering. The parent has been paring its position in stages ever since, and the July tender offer is the latest step, not the first.
The filing also discloses that ENEOS agreed with a group of joint bookrunners, including Daiwa Capital Markets Europe, Nomura International, Morgan Stanley & Co. International, Merrill Lynch International, J.P. Morgan Securities and Goldman Sachs International, not to sell further JX Metals shares between May 18 and November 29, 2026 (London time), with this specific tender offer carved out as the one exception. Separately, the filing states ENEOS's purpose in holding the remaining stake as maintaining its relationship with JX Metals, without elaborating further.
The amendment is the fifth such change report ENEOS has filed on this holding since JX Metals' listing, a paper trail of a parent company gradually loosening its grip on a subsidiary it took public last year.
