OSI Systems (OSIS) shares dropped more than 7% in recent trading on Thursday after a short seller report said that the company misrepresented its financials regarding its Mexican business.
A Culper Research report said the company was falling behind on its contract obligations with Mexico's Ministry of Defense but alleged that it had already recognized 81% of the project's product and installation revenues.
Trading volume stood at around 640,000 shares against a daily average of about 222,000.
