MAZUREK NATHAN 4

What Happened

• Nathan Mazurek, CEO of Pioneer Power Solutions, reported exercising stock options. The filing shows an exercise that acquired 1,000 shares at $2.18 per share (total cost $2,180). The same report also shows a separate 1,000-share derivative disposition recorded at $0.00 proceeds.
• This is an options exercise (transaction code M). The filing does not report an open-market sale of the acquired shares for cash.

Key Details

• Transaction date: 2026-03-02 (reported on Form 4 filed 2026-03-03)
• Exercise/acquisition: 1,000 shares @ $2.18, total $2,180
• Derivative disposition: 1,000 shares @ $0.00, total $0
• Footnote: The exercised options were fully vested as of March 10, 2017 (F1)
• Shares owned after transaction: not specified in the provided excerpt of the filing
• Timeliness: Filed the next day (appears timely; no late filing indicated)
• Transaction code: M = Option exercise/conversion

Context

• For derivative transactions like this, a $0.00 disposition line can reflect a non-cash settlement, net-share withholding for taxes, or an internal transfer, but the filing excerpt does not explain the reason. The document only shows the exercise and the separate zero-dollar disposition.
• Exercises of vested options are routine for insiders; purchases (cash paid to acquire shares) are often viewed as a more direct bullish indicator than exercises alone. This filing is factual and does not state any motive.
