Resonac Holdings' board resolved on August 25, 2026, to carry out a partial spin-off of its wholly owned petrochemicals subsidiary by handing the shares directly to Resonac's own shareholders rather than selling the business. The transaction takes effect October 1, 2026, but only if the Tokyo Stock Exchange approves the subsidiary's listing and does not later revoke that approval.
How the distribution works
Every Resonac shareholder of record will receive one share in the subsidiary for each Resonac share they hold, structured as a dividend in kind rather than a cash payout. The book value of the shares being distributed comes to ¥37,789,219,709, or ¥199.02 per Resonac share, funded out of retained earnings. Resonac is explicit that this figure reflects accounting book value as of late July 2026, not a market valuation, and the final amount will be recalculated at the effective date.
| Date | Event |
|---|---|
| September 28, 2026 (Monday) | Last day to buy Resonac shares with rights to the distribution |
| September 29, 2026 (Tuesday) | Resonac shares trade ex-rights; expected TSE listing date for the petrochemicals subsidiary |
| September 30, 2026 (Wednesday) | Dividend-in-kind record date |
| October 1, 2026 (Thursday) | Distribution becomes effective |
From full owner to minority holder
Resonac currently owns 100% of the subsidiary. Once the spin-off distribution is complete, Resonac's remaining stake will fall below 20%. That threshold matters mechanically: below it, the subsidiary stops being a consolidated business, and Resonac expects to lack even the "significant influence" needed to keep applying equity-method accounting. In practical terms, a business that has sat inside Resonac's numbers will largely disappear from them.
Resonac says the exact hit to its consolidated results is still being worked out, but under IFRS it plans to classify the segment as a disposal group held for distribution to owners starting in the third quarter, reporting its results as discontinued operations rather than folding them into continuing business figures. On deconsolidation, Resonac will also revalue any shares it keeps in the subsidiary at fair value, with the resulting gains or losses booked to discontinued operations.
The business changing hands
The subsidiary, capitalized at ¥110mn and established in August 2024, makes basic petrochemicals such as ethylene and propylene, acetic-acid-based organic chemicals, and synthetic resin products, with its main office in Oita and a Tokyo headquarters in Minato ward. For the year ended December 2025, it reported sales of ¥303.9bn, operating profit of ¥4.21bn, ordinary profit of ¥5.59bn, and net profit attributable to shareholders of ¥3.1bn, on total assets of ¥191.2bn and net assets of ¥74.6bn. The subsidiary carried out a large stock split on August 10, 2026, converting 200,100 shares into 234,415,443 shares, and the reported per-share figures assume that split had already applied for the full 2025 fiscal year.
All of the subsidiary's current staff are seconded from Resonac or its Resonac unit, and the company plans to convert them to direct employees ahead of the listing. Resonac also says it intends to unwind most ongoing commercial dealings with the newly independent company, keeping only transactions it judges necessary and on appropriate terms.
The listing is scheduled but not guaranteed. Resonac's own notice makes the whole plan conditional on Tokyo Stock Exchange approval standing without withdrawal, leaving the October 1 effective date as a target rather than a locked-in outcome.
