[Form 4] Serve Robotics Inc. Insider Trading Activity

Rhea-AI Filing Summary

Amplitude (AMPL) Form 4 filed 08/06/2025: CEO, Director and 10% owner Spenser Skates reported a bona-fide gift (transaction code G) of 1,010,000 Class B common shares—convertible 1-for-1 into Class A—to his spouse on 08/04/2025. As a gift, the shares were transferred at $0; no market sale occurred.

Post-transaction the insider’s holdings stand at 5,342,146 Class B shares held directly and 1,010,000 shares held indirectly through his spouse. Because the shares remain within the immediate family, aggregate insider ownership and potential voting power are largely unchanged, and no additional public float is created. The filing therefore carries minimal market impact and is primarily an administrative disclosure.

Insights

Securities Analyst

TL;DR: 1.01 M shares gifted, no cash, negligible market impact.

The transaction is coded “G,” confirming a bona-fide gift to the insider’s spouse. Although 1 million shares is sizable, the stock stays within the family trust circle, so effective control and overall insider stake (≈6.35 M shares) are intact. No price was reported, eliminating dilution or sale pressure. Investors should see this as neutral housekeeping rather than a signal on fundamentals or valuation.
