Rhea-AI Filing Summary

Dillon James, Chief Marketing Officer of TIGO ENERGY, INC. (TYGO), reported a Form 4 disclosing an exempt disposition of 11,050 shares of common stock on 09/16/2025 to satisfy tax withholding from vested restricted stock units (RSUs). After the withholding, the reporting person beneficially owns 182,756 shares of common stock. The filing lists RSU grants from August 11, 2023; September 16, 2024; and August 1, 2025, with standard one-third annual vesting over three years subject to continued service. The transaction was coded as an exempt disposition under Rule 16b-3(e) and was reported as a Form 4 filed by one reporting person.

Positive

• Administrative tax withholding on vested RSUs was handled via exempt disposition, not an open-market sale
• Reporting person retains 182,756 shares after withholding, indicating continued equity ownership
• RSU grants and vesting schedule disclosed with clear one-third annual vesting from three grant dates

Negative

• 11,050 shares withheld reduces the reporting person’s share count (administrative dilution of their holdings)
• No information on total outstanding shares is provided, so percentage ownership impact cannot be determined from this filing alone

Insights

Securities Insider Transactions Analyst

TL;DR: Routine insider tax-withholding on RSU vesting; no open-market sale reported and beneficial ownership remains substantial.

The Form 4 documents a common, non-dispositive action: 11,050 shares were withheld to satisfy tax obligations when previously granted RSUs vested. This was reported as an exempt disposition under Rule 16b-3(e), indicating the shares were not sold on the open market. The reporting person retains 182,756 shares after the withholding, and the filing identifies multiple RSU grant dates with standard staggered vesting schedules. For investors, this is an administrative equity-management event rather than a liquidity-driven insider sale.

Compensation & Corporate Governance Specialist

TL;DR: Vesting and withholding reflect standard equity compensation mechanics; disclosure is complete and consistent with plan terms.

The footnotes confirm RSU grants from 2023, 2024, and 2025 under the issuer’s 2023 Incentive Plan with one-third annual vesting and delivery upon vesting. The withheld shares satisfy tax-withholding obligations arising from vesting, consistent with an exempt disposition treatment. No derivative transactions or additional disposals are reported. The disclosure helps confirm alignment of executive compensation with time-based vesting requirements.
