Gross margin deteriorated from 29.7% in Q1 2025 to 21.9% by Q4 2025, an 8-percentage-point erosion that the lawsuit contends was foreseeable and inadequately disclosed to shareholders.<\/p>\n<p><b>How the Market Repriced PSIX After Concealed Risks Surfaced<\/b><\/p>\n<p>The market&#8217;s repricing of PSIX shares occurred across two corrective events. On November 7, 2025, following Q3 results that revealed a 5.0% year-over-year gross margin decline and a downward revision of annual sales growth expectations to 45%, shares fell $15.55, or 19.14%, closing at $65.69 on heavy volume. This first correction removed a portion of the artificial inflation that the complaint alleges had been sustained by management&#8217;s repeated characterization of margin pressure as merely &#8220;temporary.&#8221;<\/p>\n<p>The second and larger correction came on March 3, 2026, when Q4 results disclosed an 8% year-over-year gross margin collapse and an outlook limited to only &#8220;moderate margin improvement.&#8221; The filing states that the Company simultaneously revealed it was only now &#8220;executing specific actions to improve supply chain performance and manufacturing cost structures,&#8221; suggesting these problems had persisted far longer than investors were led to believe. Shares shed $24.84, or 28.97%, in a single session.<\/p>\n<p><b>The Alleged Artificial Inflation and Its Removal<\/b><\/p>\n<p>The lawsuit maintains that PSIX securities traded at artificially inflated prices throughout the Class Period because:<\/p>\n<ul class=\"bwlistdisc\">\n<li>Management touted a pivot to &#8220;higher growth, higher-margin markets&#8221; while gross margins declined every consecutive quarter from 29.7% to 21.9%<\/li>\n<li>The Company characterized production challenges as &#8220;temporary inefficiencies&#8221; through multiple quarterly reports, even as the problems worsened<\/li>\n<li>Sales growth decelerated sharply from 74% (Q2) to 65% (Q3) to 33% (Q4), contradicting the narrative of accelerating data center demand<\/li>\n<li>The full scope of supply chain failures and manufacturing cost structure problems was not disclosed until the final corrective event<\/li>\n<\/ul>\n<p><a rel=\"nofollow\" href=\"https:\/\/cts.businesswire.com\/ct\/CT?id=smartlink&amp;url=https%3A%2F%2Fzlk.com%2Fpslra-1%2Fpower-solutions-international-inc-lawsuit-submission-form%3Fprid%3D184835%26wire%3D2&amp;esheet=54480703&amp;newsitemid=20260407495688&amp;lan=en-US&amp;anchor=Join%20the%20PSIX%20recovery%20action&amp;index=18&amp;md5=5caab64f3534095861feadc288624fcc\">Join the PSIX recovery action<\/a> or call (212) 363-7500.<\/p>\n<p><i>&#8220;When companies fail to disclose material information, shareholders may suffer significant losses.
