ATRC does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

AtriCure published its Q2 2026 earnings press release on July 23, 2026, and scheduled a conference call for 4:30 p.m. Eastern Time that same day to discuss the results. The company stressed that this 8-K is just “furnishing” the release—not officially “filing” it—so it won't trigger liability under Section 18 of the Exchange Act.
