Across its top 20 institutional holders, ZNTL's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 17/100, avg. turnover score 45/100).
ZNTL ranks #4261 out of 37503 tracked stocks by institutional interest, inside the more closely watched half of our coverage.
ZNTL is a disclosed holding of Two Sigma (Two Sigma Investments), one of the tracked superinvestors on AlphaSMO — it makes up 0.0% of that fund's own 13F portfolio.
ZNTL is a top-conviction position for 5AM Venture Management, LLC — at 6.7% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in ZNTL belongs to Squadron Capital Management LLC, but the position matters far more to 5AM Venture Management, LLC, who has 6.7% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.
BlackRock has added to its ZNTL position for two straight quarters, increasing it by $16.5M to reach $18.2M today.
JPMorgan has trimmed its ZNTL position for two straight quarters, cutting it by $146.3K while still holding $103.4K.
ZNTL is down 2.1% today, but institutions show net buying of $29.3M this quarter — a divergence between today's price move and the underlying institutional flow.
ZNTL reported a net loss of $139.5M over the trailing twelve months.

Top 5 Institutional Movers
ZNTL 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.
