Gabel Daniel G. 4

What Happened
Daniel G. Gabel, Chief Financial Officer of ONE STOP SYSTEMS, was granted 55,239 restricted stock units (RSUs) on February 7, 2026. The award is reported at a $0.00 acquisition price (an RSU grant/award rather than an open‑market purchase), so no cash was exchanged at grant; future value depends on OSS’s share price at vesting.

Context
This was a compensation grant (RSUs) given to an executive as part of service/retention, not an open-market buy or sale. RSU grants are common executive compensation and their ultimate value depends on OSS’s future stock price and the grant’s vesting schedule. This type of filing documents ownership change but does not, by itself, indicate an insider’s trading preference.
