Value vs. prior quarter

Great Mountain Partners’ reported 13F holdings total $9.28M across 1 positions as of 30 June 2026. The ten largest make up 100.0% of it, and its value fell 38.5% from the prior quarter.

Form 13F lists long positions in exchange-traded securities over which the filer had investment discretion, valued at quarter end. It excludes cash, bonds held outside 13(f) securities, private funds, and assets the firm does not have discretion over, so the $9.28M reported here is not the firm's $14.11B in regulatory assets, and it does not represent any individual client's portfolio.
