Erthos Inc. looks fair against its niche peers and is at-risk on financing cadence.

Synthesized from the figures below est. — every claim rests on a number shown on this page. Valuation uses the energy sector profile.

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

Fair
  • Modeled value is 1.24× the median modeled value of Series B Other Energy companies in 2022–2024 (44 peers) — value vs value, same stage and era.
  • Within the normal band (124% of peer median) for its niche.
At-risk
  • Last raise 2.8 yr ago; this sector typically re-raises about every 12 months.
  • Past due for a raise versus sector cadence — watch for distress or a bridge.

Amount raised vs valuation, by round

Solid bars are reported offering amounts reported; hatched bars are the modeled post-money valuation est. — both on one shared scale so you can read raise-vs-worth at each round directly. Use the toggles to overlay data labels and the niche-peer / market average value lines.

How it compares to the market

Benchmarked against 2048 companies in Other Energy. 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) 12× above median
This company$41.4M
Sector median$3.4M
Latest round — vs other Series B rounds in sector (real $, this stage) 0.8× of median
This company$15.0M
Sector median$19.1M
Modeled value — vs sector median (estimate, all stages) 9.0× above median
This company$153.0M
Sector median$17.0M

Raised more than 88% of sector peers (real $). Modeled value above 87% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Series B) 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 #13 of 44.
