Shares of Janus International Group (JBI) plummeted 11.52% in pre-market trading on Thursday following the release of its third-quarter 2025 financial results, which fell short of analyst expectations across multiple key metrics.

The self-storage and commercial door solutions provider reported adjusted earnings per share (EPS) of $0.16, missing the IBES estimate of $0.20. Revenue for the quarter came in at $219.3 million, falling short of the anticipated $225.6 million. Additionally, Janus International's adjusted EBITDA was $43.6 million, significantly below the IBES estimate of $49.9 million.

The company's disappointing performance was primarily driven by a 20.1% decrease in Commercial and Other revenues, which more than offset a 3.7% increase in total Self-Storage revenues. Janus International also updated its full-year 2025 guidance, now expecting revenue between $870 million and $880 million, and adjusted EBITDA between $164 million and $170 million. The revised outlook and weaker-than-expected quarterly results have clearly shaken investor confidence, leading to the substantial pre-market sell-off.
