[Form 4] AtriCure, Inc. Insider Trading Activity

Rhea-AI Filing Summary

AtriCure, Inc. (ATRC) Form 4: Director Regina E. Groves sold 2,452 common shares on 08-06-2025 at a weighted-average price of $36.82, a transaction valued at roughly $90 k.

After the sale, Groves directly owns 33,715 shares. No derivative securities were involved and the filing does not cite a Rule 10b5-1 trading plan. There are no disclosures of additional insider transactions, compensation changes, or company events in this filing.

The reported sale reduced her direct position by about 6.8% (from 36,167 to 33,715 shares). While a single Form 4 offers limited context, investors often track insider activity as a sentiment gauge. This transaction is modest relative to AtriCure’s average daily volume and does not, by itself, indicate a change in corporate fundamentals.

Positive

• None.

Negative

• Director sold 2,452 shares worth about $90 k, reducing her direct stake by ~6.8%, which some investors may view as a cautious signal.

Insights

Securities Analyst

TL;DR: Modest insider sale; unlikely to materially impact valuation.

Groves’ ~$90 k disposition represents a small fraction of both her holdings and ATRC’s typical trading volume. The absence of a 10b5-1 reference suggests a discretionary sale, but the stake reduction (≈6.8%) is not large enough to infer strategic shifts. Insider selling can raise caution flags, yet the limited size and lack of accompanying negative disclosures keep the overall signal neutral. Still, investors tracking governance may note that this is the second reported sale in the past few months, warranting continued monitoring of board-level activity.
