According to the Complaint, the Company made false and misleading statements to the market. Quanex &#34;underinvested&#34; in tooling and equipment maintenance for its Tyman Mexico facility. The Company's tooling and equipment had degraded to &#34;catastrophic&#34; levels due to its poor maintenance practices. The Company was likely to incur significant expenses to repair equipment, delaying the benefit of its Tyman integration. The Company was aware of these issues before they became serious. Based on these facts, the Company's public statements were false and materially misleading throughout the class period. When the market learned the truth about Quanex, investors suffered damages.
