Rengo's Q1 Operating Profit Jumps 73% as Price Revisions Land Across All Four Segments

Price revisions, and they reach everywhere

Rengo Co., Ltd. (TSE: 3941), Japan's largest corrugated packaging group, published consolidated results for the three months to June 30, 2026 on August 5, 2026 under Japanese GAAP. Net sales rose 10.6% to ¥275,750 million, operating profit 72.5% to ¥17,898 million, ordinary profit 80.3% to ¥18,903 million and net profit 92.8% to ¥11,575 million, for earnings per share of ¥46.97 against ¥24.22. Comprehensive income was ¥25,616 million against a ¥3,299 million loss.

The company gives price revisions as the driver, and states the counterweight in the same breath: the gains came despite increases in fixed costs and logistics expenses. The margin move — 6.5% against 4.2% — is what a price-led recovery looks like when volumes are broadly steady, and the fact that all four segments improved profit is what distinguishes it from a one-business rebound.

The four segments, in order of how much moved

Paperboard & Paper Processing, the core, grew external revenue 6.0% to ¥138,557 million and profit 46.7% to ¥10,137 million. Flexible Packaging was the standout on profit: revenue up 14.1% to ¥56,080 million and profit up 114.2% to ¥5,771 million. Alongside price revisions, the company notes that flexible and heavy-duty packaging both saw pull-forward demand as customers ordered ahead against uncertainty in the Middle East — a demand effect that by its nature borrows from later quarters.

Heavy-Duty Packaging grew revenue 13.7% to ¥12,903 million and profit 44.8% to ¥695 million. Overseas grew revenue 18.7% to ¥57,941 million and swung to a ¥699 million profit from a ¥109 million loss, helped by an increased number of consolidated subsidiaries and by strong heavy-duty packaging demand in North America and Southeast Asia.

Balance sheet grows with the business; guidance already 39% covered

Total assets rose 3.1% from the March year-end to ¥1,353,480 million and net assets 2.8% to ¥543,422 million, leaving the equity ratio essentially flat at 37.2% against 37.3%.

Guidance is unchanged: net sales of ¥1,090,000 million (+8.1%), operating profit of ¥46,000 million (+24.0%), ordinary profit of ¥44,000 million (+17.6%) and net profit of ¥31,000 million (+47.6%), for earnings per share of ¥125.78. The quarter has banked 38.9% of the full-year operating-profit target in three months, which leaves the forecast looking conservative on its face — though the pull-forward demand noted above is one reason the company may not want to extrapolate the run rate. The annual dividend rises 25.0% to ¥50.00 from ¥40.00, split ¥25.00 interim and ¥25.00 final.
