[Form 4] AppFolio, Inc. Insider Trading Activity

Rhea-AI Filing Summary

AppFolio, Inc. (APPF) – Form 4 insider transaction

On 08/01/2025, director and >10% shareholder Maurice J. Duca disclosed the sale of 5,700 Class A common shares through a pre-arranged Rule 10b5-1 plan adopted 13-Dec-2024.

• Direct account: 2,500 shares sold at $283.00-$310.78; direct holdings decline to 83,295 shares.
• Family Trust: 1,900 shares sold at $283.00-$308.18; trust holdings fall to 58,200 shares.
• Pension Trust: 1,300 shares sold at a weighted average $291.04; pension balance now 43,700 shares.

Weighted average sale prices cluster around $298-$307, implying gross proceeds of roughly $1.7 million. No derivative securities were reported. After the transactions, Duca (including entities he manages or advises) continues to report beneficial ownership, direct or indirect, of approximately 364,524 shares, though he disclaims pecuniary interest in several LLC positions.

The filing signals a modest reduction (<~2% of his reported holdings) but maintains a substantial insider stake, mitigating concerns usually associated with large insider sales.

Insights

Equity Analyst

TL;DR: 5,700-share sale (~$1.7 M) by 10% owner is modest, under 10b5-1 plan; insider still holds ~364k shares—sentiment slightly negative.

The sale represents about 2 % of Mr. Duca’s reported ownership. Use of a pre-scheduled 10b5-1 plan limits information-content related to timing, yet continued divestiture following prior sales may raise incremental supply concerns. Importantly, his aggregate stake remains large, aligning interests with shareholders. Given APPF’s average daily volume (~200 k shares), the trade size is immaterial to liquidity. From a valuation perspective, insider selling at ~$300 suggests comfort with current pricing but does not necessarily indicate overvaluation. Overall impact: mildly negative on perception, but not fundamentally material.
