INFRONEER Holdings Inc. plans to issue 47,826,100 new ordinary shares and use the money first to repay short-term loans taken out for two acquisitions. The board resolved on 2 October 2026 to proceed with a combined domestic and overseas offering. Nothing has been priced yet, and the headline figures are ceilings built on a pre-announcement share price.
Where the money goes
Estimated net proceeds total at most ¥147.24bn: ¥95.64bn from the overseas tranche, ¥32.36bn from the domestic tranche and up to ¥19.24bn if the over-allotment-linked share issue goes ahead in full. All three figures rest on the Tokyo Stock Exchange closing price of 25 September 2026, not on a final offer price.
The company says ¥117bn will repay short-term borrowings by December 2026. Any remainder is reserved for strategic M&A by the end of March 2028, centred on contracting, infrastructure operation and stadium and arena businesses. If that M&A does not happen, the remainder goes to existing borrowings.
The ¥117bn comprises two loans. The first is ¥77bn, due 25 March 2027. It is the balance of a ¥95bn facility from Sumitomo Mitsui Banking Corporation and Sumitomo Mitsui Trust Bank, taken out to buy the contractor formerly called Sumitomo Mitsui Construction, which was renamed on 1 October 2026. INFRONEER made that company a wholly owned subsidiary on 23 December 2025 for ¥94.13bn. The second is ¥40bn, due 1 July 2027, borrowed from the same banking group's lending arm and SBI Shinsei Bank to buy a water-treatment company. That purchase closed on 1 July 2026 at ¥75.20bn.
How the shares are split
The 47.83mn new shares are a target split. Final numbers between the domestic and overseas tranches will be fixed on the pricing date, which falls between 21 and 26 October. Overseas sales in the United States are limited to qualified institutional buyers under Rule 144A.
| Tranche | Shares | Status |
|---|---|---|
| Overseas offering | 35,750,000 | Target; Rule 144A in the US |
| Domestic offering | 12,076,100 | Target; all bought by underwriters |
| Total new shares in public offering | 47,826,100 | Sum of the two targets, per the company |
| Over-allotment sale (borrowed shares) | 7,173,900 | Upper limit; may be reduced or not occur |
| Third-party issue to SMBC Nikko Securities | 7,173,900 | Upper limit; depends on over-allotment |
SMBC Nikko Securities may sell up to 7,173,900 borrowed shares alongside the domestic offering, a standard over-allotment arrangement. It would then take up to the same number of new shares to return them. It will subscribe only for shares it has not bought back in the market, so the third-party issue can shrink or not happen at all. Those shares are a ceiling, not additional certain supply.
Price, timing and dilution
The indicative range is 0.90 to 1.00 times the Tokyo close on the pricing date. Payment for the main offering falls between 27 and 30 October. The third-party issue pays between 25 November and 1 December. No underwriting fee is paid; the underwriters keep the gap between offer price and the amount paid to the company.
Ordinary shares outstanding would rise from 274,845,024 to 322,671,124 after the main offering, and to 329,845,024 if the third-party issue is fully taken up. The company's 2029 green convertible bonds represent 36,135,870 potential shares at the current conversion price, 10.96% of the enlarged ordinary share count.
INFRONEER says the raise does not change its current-year forecast. It also lifted its dividend floor to ¥90 per share from the year ending March 2027, from ¥60, with a payout ratio of at least 40%. A lock-up of 180 days from delivery covers the company and a major shareholder, though the lead coordinators can waive it.
