Highlights

How we pick these

Strengths

  • Fast growth. Revenue grew 28.9% over the last 12 months, against a median of 12.0% for application software companies we cover.
  • Margins widening. Operating margin is up 7.7 points on a year ago.
  • Net cash. Cash exceeds long-term debt by $0.8bn.

Things to watch

  • Results due soon. Results are expected around 5 November; the share price can move sharply on the day.
  • Loss-making. Operating margin is -1.9%: costs exceed revenue.
  • Share dilution. Diluted shares rose 10.0% in a year.
  • High earnings multiple. The shares trade at 969 times the last 12 months' earnings, so expectations are demanding.
  • Volatile shares. Over the past year the shares showed annualised volatility of 74% and a beta of 0.5 against the S&P 500.
  • Heavily shorted. 16.0% of the shares available to trade are sold short (3.4 days of average volume to cover).

Valuation

Klaviyo, Inc. valuation models and calculator

Fundamentalytics rating

model v1.6 · 2026-11-03

Not rated: valued with our growth model, which doesn't carry a Buy/Hold/Sell rating yet.

Valuation models

We value Klaviyo, Inc. as an operating company, with every model that fits that kind of business. Cost of equity 9.5%: the 10-year Treasury yield (4.9%) plus a beta of 1.01 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. ~$7.8 ~$6.0–$9.3 Primary model, counts double
Forward price-to-earnings vs peers Next year's consensus earnings per share times peers' typical (harmonic-mean) forward price-to-earnings. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$14 ~$12–$24 Included
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. ~$1.8 ~$12–$33 Left out: out of range vs price (0.08x)
Revenue-to-maturity model Revenue grown to maturity with the cash margin moving to the industry's; for companies not yet profitable. ~$26 ~$21–$30 Included
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. ~$14 ~$7.8–$26 3 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Klaviyo, Inc. with Application Software in our coverage, using third-party market data.
