NX Quanex Corp

Quanex Building Products Corporation (NYSE: NX) (“Quanex” or the “Company”) today announced that it has closed on its acquisition of Tyman plc (“Tyman”), creating a comprehensive solutions provider in the building products industry.

“We are excited to welcome the Tyman team. This transaction accelerates our growth and value creation by delivering best-in-class building products solutions to OEMs in the building products industry,” said George Wilson, Chairman, President and Chief Executive Officer of Quanex. “The acquisition of Tyman directly aligns with our ‘BIGGER’ strategy and, as a combined company, our scale and reach will enable us to build on our leading positions across an enhanced offering of differentiated engineered components. Our teams are focused on executing a smooth integration as we work to realize the operational and financial benefits of the transaction for the benefit of our employees, customers and stockholders.”

The transaction creates a larger, more diversified supplier of components to OEMs; strengthens brand leadership by adding Tyman’s highly recognizable brands with wide customer bases; and enhances the combined company’s financial profile by accelerating growth and increasing profitability through greater scale and stronger cash flow. The Company intends to complete approximately 50% of the integration within the first 12 months and expects the acquisition to be meaningfully accretive to earnings within the first full year after closing.

In connection with the acquisition, Quanex will grant a Board Observer right to Teleios Global Opportunities Master Fund (“Teleios”), formerly the largest shareholder of Tyman. Teleios committed to the all-share alternative in support of the transaction and the Quanex leadership team. Quanex is entitled to terminate the agreement with Teleios after the Company’s annual meeting of shareholders in 2026.

In connection with the completion of the transaction, trading in Tyman’s common stock on the London Stock Exchange was suspended at 7:30 a.m. today (London time) and will be cancelled with effect at 7:30 a.m. tomorrow (London time).
