View all 360 holding institutions

Across its top 20 institutional holders, EOSE's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 10/100, avg. turnover score 45/100).

Notable Holders

EOSE ranks #1735 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

EOSE is a disclosed holding of Ken Griffin (Citadel Advisors LLC), one of the tracked superinvestors on AlphaSMO — it makes up 0.0% of that fund's own 13F portfolio.

EOSE is a top-conviction position for Crystal Cove Asset Management, LLC — at 27.5% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in EOSE belongs to California State Teachers Retirement System, but the position matters far more to Crystal Cove Asset Management, LLC, who has 27.5% 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.

Bouvel Investment Partners, LLC has added to its EOSE position for two straight quarters, increasing it by $264.6K to reach $827.6K today.

Lauer Wealth, LLC has trimmed its EOSE position for two straight quarters, cutting it by $766.4K while still holding $245.6K.

EOSE is down 15.7% today, but institutions show net buying of $330.8M this quarter — a divergence between today's price move and the underlying institutional flow.

Company Fundamentals

EOSE reported a net loss of $528.7M over the trailing twelve months.

  • Not yet profitable — net loss of $528.7M over the trailing twelve months
  • Revenue grew 533.9% year over year
  • Net income improved year over year, from -$818.8M to -$528.7M
  • Operating cash flow was negative, using $211.2M in cash
  • Current ratio of 4.94x — enough short-term assets to cover short-term liabilities

Smart Money Convergence

EOSE 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 2026-09-30 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.

Eos Energy Enterprises announced a leadership transition on August 24, 2026: it's consolidating sales, business development, government affairs, marketing and communications under one unified commercial organization, and Michelle Buczkowski, formerly Chief Administration Officer, has been appointed Chief Commercial Officer. Current CCO Nathan Kroeker will stay on through October 20, 2026 to support an orderly handover before departing, and while a separation agreement is expected, its terms haven't been finalized yet — any material terms will be disclosed in an amendment to this report. As part of her promotion, Buczkowski's base salary rose from $385,000 to $440,000, and her target annual short-term incentive was increased to 100% of base salary.
