POWER SOLUTIONS INTERNATIONAL, INC. 8-K

What Happened Power Solutions International, Inc. (PSIX) announced on March 13, 2026 (Form 8-K) that it held two investor calls on March 11, 2026 with pre-registered investors and analysts. The company says an unknown attendee posted a purported transcript of one call on X (formerly Twitter) shortly after the calls, despite instructions that the calls were not to be recorded or disseminated. PSI disclaims that post in its entirety and attached an official summary of the calls as Exhibit 99.1.

Key Details

• Two investor calls were held on March 11, 2026; attendees were pre-registered investors and analysts who requested to speak with management.
• PSI became aware of the unauthorized X post on March 12, 2026.
• The company states the post was unauthorized and expressly disclaims its content.
• An official Q&A summary from the March 11 calls is included as Exhibit 99.1 to the 8-K.

Why It Matters This is a Regulation FD disclosure meant to correct or clarify market information after an unauthorized publication. For investors, the takeaway is to rely on the company’s official statements (the attached Exhibit 99.1) rather than an unverified transcript posted by an unknown third party. The filing does not report financial results, executive changes, or other material corporate transactions—only a market disclosure about the integrity of investor-call information.
