Valuation models

We value Rapid Micro Biosystems, Inc. as an operating company, with every model that fits that kind of business. Cost of equity 10.2%: the 10-year Treasury yield (4.9%) plus a beta of 1.16 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
Growth cash-flow model Revenue for this year and next from analysts' consensus, then growth fading to 2.5%; the operating margin moving to profitable peers'; investment needed per dollar of growth from peers; reduced by a failure probability. For young or fast-growing companies. The starting margin is normalized to between -100% and 60%; net margin is a proxy when operating income is not tagged. Uses analysts' consensus estimates (third-party data), not our forecasts. — Does not apply: the projected cash flows don't support a positive value
Price-to-earnings vs peers Earnings per share times peers' typical (harmonic-mean) price-to-earnings. — Does not apply: no positive earnings in the latest twelve months
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. — Does not apply: the model gives no positive value
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. — Does not apply: return on equity is not positive
Forward price-to-sales vs peers Next year's consensus sales per share times peers' typical forward price-to-sales; only when earnings are negative. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$3.1 ~$2.3–$6.8 Included, half weight
Revenue-to-maturity model Revenue grown to maturity with the cash margin moving to the industry's; for companies not yet profitable. — Does not apply: revenue and margins don't support a positive value
Combined value Weighted average of the models that apply: the primary model (growth cash-flow model) counts double. Models more than 5x or less than 0.2x the share price, or more than 3x away from the other models' median, are left out. ~$3.1 ~$2.3–$6.8 1 model

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Rapid Micro Biosystems, Inc. with Life Sciences Tools & Services in our coverage, using third-party market data.

Moat

12 /100

Weak moat

How hard Rapid Micro Biosystems's competitive advantage looks for rivals to wear away, judged from 6 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 0 / 20

    Net income has been a median -42.3% of total assets over 6 years.

  • Durability 10 / 20

    Operating margin has been a median -197.4%; its worst year was -334.6%.

  • Cash conversion 0 / 20

    Free cash flow was positive in 0 of 6 years, at a median -182.2% of revenue.

AI disruption exposure: Medium. In this industry, AI could change how the product is made or sold, without replacing the core asset. The score above includes a 5-point deduction for that exposure (17 before it).
