Analyst read est. — computed against this company's niche peers in the same era. Inputs shown; not a quoted figure.

Under-valued
  • Modeled value is 0.24× the median modeled value of Series C Pharmaceuticals companies in 2022–2024 (30 peers) — value vs value, same stage and era.
At-risk
  • Last raise 3.6 yr ago; this sector typically re-raises about every 13 months.
  • Past due for a raise versus sector cadence — watch for distress or a bridge.

How it compares to the market

Benchmarked against 1613 companies in Pharmaceuticals. Each bar is a median (the middle company, not an average — outliers don't skew it). Two yardsticks: real money raised (reported on Form D) and modeled value (our estimate est.). These are whole-sector medians across all stages, except the per-stage row.

Total raised — vs sector median (real $, all stages) 13× above median
This company$109.2M
Sector median$8.1M
Latest round — vs other Series C rounds in sector (real $, this stage) 0.2× of median
This company$9.2M

This company$139.4M
Sector median$76.1M

Raised more than 92% of sector peers (real $). Modeled value above 61% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Series C) that last raised in the same ~3-year era, ranked by modeled value est. (not money raised). This is the exact set the analyst read compares against, so a like-for-like cohort is what makes "over/under-valued" meaningful. This company ranks #26 of 30.
