How Active Membranes's valuation is determined

Private company valuations aren’t quoted on an exchange — they’re established in moments: a priced funding round sets a post-money valuation, secondary trades print at a price per share, and SEC-registered funds holding the stock report fair-value marks in their N-PORT filings.

For Active Membranes, too few pricing signals exist to publish a composite mark; the figures above reflect the most recent observed valuation event. Full methodology →
