How Spar Systems'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 Spar Systems, the most current credible signal sets the number and the older ones confirm it: a live secondary-market price first, then three or more recent prints, then institutional fund marks, and otherwise the last priced round, which never decays. The valuation is the last round’s post-money moved by the price change since that round, so no share count is assumed. Today it is set by its last priced round. Question about this number?
