Nippon Sheet Glass, the Japanese parent company of St Helens-based Pilkington, is to be taken private in a proposed £2.77bn takeover backed by Apollo-managed funds, in a deal the US investor said would be its biggest private equity investment in Japan so far. The transaction, valued at nearly $3.7bn or about ¥590bn in enterprise value, would see Apollo invest fresh equity into NSG Group as part of a wider capital restructuring.
NSG said the agreement would create a “new” NSG Group through a package of measures designed to strengthen its balance sheet and support long-term growth. Alongside Apollo’s investment, the company’s principal lenders will convert part of their outstanding loans into equity through a debt-to-equity swap worth ¥140bn, while Class A preferred shareholders are expected to convert their holdings into common shares and support the relevant resolutions at the annual general meeting.
The company said it would be de-listed and become privately held through a share consolidation process, with Apollo funds subscribing for ¥165bn of shares through a third-party allotment. NSG said its day-to-day operations were expected to continue as normal before and after the transaction, while the restructuring would help reduce interest costs, secure liquidity for reforms and investment, and put the business on what it described as a more sustainable long-term growth path.
Apollo said NSG’s position in architectural, automotive and technical glass, together with its manufacturing base and customer relationships, gave it scope to benefit from demand for energy-efficient building glass, advanced automotive glazing and solar-related products. Tetsuji Okamoto, Apollo’s lead partner for Asia Pacific private equity, said the deal brought together Apollo’s operational experience and NSG’s manufacturing heritage, and described the company as “a foundational player in the global glass industry”.
Munehiro Hosonuma, NSG’s president and chief executive, said the company would seek the understanding of shareholders, lenders and other stakeholders as it pursued what he called “fundamental measures” for long-term growth. He said the partnership with Apollo and the group’s principal lenders would allow NSG to strengthen its finances, invest in people and technology, and continue work towards its medium-term “2030 Vision: Shift the Phase” plan.
The proposals remain subject to shareholder approval at NSG’s annual general meeting, scheduled for late June, as well as regulatory clearances in the relevant jurisdictions. Apollo said the transaction was expected to complete by around March 2027, although NSG said the timetable would depend on when the required approvals and conditions were satisfied. Apollo added that this would be its fifth private equity fund investment in Japan.
Why This Matters: NSG’s fundamental strategic steps are driven by the urgent need to fix a broken balance sheet and free the business from public-market constraints to restore competitiveness. Persistent losses, weak free cash flow and a debt load of over ¥570 billion have left the group over‑leveraged, paying a rising interest burden and missing its own 2030 targets. The Apollo-led ¥165 billion equity injection, coupled with a ¥140 billion quasi debt–equity swap and UK debt repayment, is designed to slash leverage, stabilise cash flow and fund capex in higher value-added, solar and environmental-compliance glass. Taking the company private is presented as the only way to execute deep restructuring at speed while offering existing shareholders a cash exit at a premium.
