Kirby McInerney LLP is encouraging investors who suffered losses on their investment in Masonite International Corporation to contact the firm by April 7, 2026 to discuss their rights or interests in a securities fraud class action lawsuit. The lawsuit alleges that Masonite failed to disclose that it had received multiple formal acquisition offers from Owens Corning to purchase all outstanding shares of Masonite common stock at prices significantly above the then-current market prices.

Why it matters

This case highlights the importance of public companies fully disclosing material information to investors, especially regarding potential acquisition offers that could significantly impact the stock price. Investors rely on accurate and timely disclosures to make informed decisions, and failure to do so can lead to legal action.

The details

The lawsuit has been filed on behalf of investors who purchased Masonite securities during the period of June 5, 2023 through February 8, 2024. The lawsuit alleges that Masonite knew it had received multiple formal acquisition offers from Owens Corning to purchase all outstanding shares of Masonite common stock at prices significantly above the then-current market prices, but failed to disclose this information. On February 9, 2024, Masonite finally announced the execution of an arrangement agreement with Owens Corning, revealing that Owens Corning had been willing to acquire all of Masonite's outstanding stock for $133 per share, a significant premium over Masonite's then-current stock price of $94.09 per share.

  • The Class Period is from June 5, 2023 through February 8, 2024.
  • Masonite received the first acquisition offer from Owens Corning eight months prior to the February 9, 2024 announcement.
  • Masonite issued a press release on February 9, 2024 announcing the execution of the arrangement agreement with Owens Corning.
