In 30 separate trades executed throughout the day, he sold a total of 2,200 shares of FICO common stock at prices ranging from $1,650.00 to $1,887.71 per share. The weighted-average prices for many trades are disclosed in the footnotes.

Following the transactions, Lansing’s direct beneficial ownership declined from 44,338 to 42,138 shares, a reduction of roughly 5% of his personally held stake.

• Form type: Form 4 – Statement of Changes in Beneficial Ownership
• Insider role: Director; President & CEO
• Transaction date: 07/08/2025  |  Filing date: 07/10/2025
• Total shares sold: 2,200  |  Remaining ownership: 42,138 shares
• Approximate sale proceeds (calculated from disclosed price ranges) exceed $3.6 million.

The disposal represents routine diversification rather than a wholesale exit, but investors typically view unplanned CEO selling as a modestly negative signal, particularly given the absence of a disclosed 10b5-1 plan.

Positive

• Insider retains 42,138 shares, indicating continued economic alignment with shareholders
• No derivative transactions were executed, limiting leverage-related risk

Negative

• CEO sold 2,200 shares (~5% of holdings), which may be perceived as a bearish signal
• No 10b5-1 trading plan disclosed, increasing uncertainty about the motivation behind the sale

Insights

Securities Analyst

TL;DR – CEO sold 5% of holdings; signal mildly negative, though stake remains large.

The filing shows William Lansing disposing of 2,200 shares in tightly sized lots, suggesting an algorithmic execution over a single trading session. Still owning 42,138 shares, he retains meaningful exposure, but the timing—near all-time highs around $1.7-1.9 k—implies profit-taking. Absence of a 10b5-1 flag reduces the likelihood these were pre-scheduled, increasing potential signalling value. The sale equates to roughly $3.6–$4.1 million, immaterial to FICO’s market cap but relevant for sentiment. Impact to fundamental valuation is negligible; monitor for additional parts (2 & 3) of the filing series to gauge cumulative sales.

Corporate Governance Expert

TL;DR – Insider selling is moderate and within normal diversification thresholds.

From a governance standpoint, a 5% reduction does not materially alter alignment between the CEO and shareholders. Lansing retains a sizable equity position, preserving incentive structures. The multi-part filing notation may indicate administrative batching rather than staggered selling. Unless subsequent parts reveal significantly larger disposals, this activity is not a red flag. However, investors should verify whether a 10b5-1 plan exists before drawing behavioural conclusions.
