New York, New York--(Newsfile Corp. - October 17, 2025) - Faruqi & Faruqi, LLP, a leading national securities law firm, is investigating potential claims against Quanex Building Products Corporation ("Quanex" or the "Company") (NYSE: NX) and reminds investors of the November 18, 2025 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company.

As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: (1) the Company's procedures and policies regarding tooling and equipment maintenance in its Tyman Mexico facility were significantly "underinvested"; (2) as a result, the Company's tooling and equipment conditions had significantly degraded to near "catastrophic" levels; (3) that, as a result of the foregoing, the Company was likely to incur significant costs, "pushing out the timing" of expected benefits from the Tyman integration; (4) that Quanex had previously identified the foregoing issues; and (5) that, as a result of the foregoing, Defendants' positive statements about the Company's business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

On September 4, 2025, after the market closed, Quanex announced financial results for the third quarter of the 2025 fiscal year. Among other things, the Company disclosed "operational issues related to the legacy Tyman window and door hardware business in Mexico that are ongoing" which "impacted results more than expected during the third quarter of 2025." Specifically, the Company reported a diluted EPS of ($6.04), compared to $0.77 in the prior year period and an adjusted EBIDTA of $70.30. The Company further disclosed that it was "adjusting for lower expected volumes and pushing out the timing of when [it] expect[s] to realize procurement savings" from the integration of the Tyman business.
