Smart Money Convergence

MGX 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.

Data as of 2026-08-10

2026-08-10

Metagenomi Therapeutics reported its financial results for the quarter ended June 30, 2026, along with business updates, in a press release issued on August 10, 2026. That press release is attached as Exhibit 99.1 to this 8-K. The filing is marked as "furnished" rather than "filed," meaning the information doesn't carry the usual legal liability under Section 18 of the Exchange Act. The 8-K itself just announces the results — no actual numbers are included in the excerpt, so it's not possible to say how the quarter went from this document alone.
