Verdict

Verdict

The $1B tells you…

What an investor paid for newly issued shares — a primary round, priced post-money.

How much capital arrived with it:$40Min Apr 2026.

A dated print: it moves only when a newer round is announced.

The $1.57B tells you…

At least one valuation basis is undisclosed, so the two numbers stay side by side, each with its own chip, and no ratio is scored. HeartFlow is public, and there is no Canborsa market on either name — the dated prints above stay separate from any live quote.
