Daily closes. Earnings/event dots inline.
A consensus fair price across 3 valuation methods, at three horizons. As of 2026-09-04. Estimates are diagnostics, not price targets. Short-horizon estimates are close to coin-flips, so confidence is a method-agreement read, not a prediction.
Today's peer multiple on trailing earnings, with no growth credited. This is the headline read.
Adds projected growth, so it leans optimistic by design. Read it as upside context, not a base case.
We take the 12-month fair value above and grade our own number — how the market prices this name versus what we'd justify, and where the two diverge.
At $20 TNDM trades at 1.3× p/s, below its 2.9× p/s peer median. Our $52 fair value sits well above the price. We hold it with low confidence: its earnings are too depressed to value on P/E (we anchor on sales instead) and the peer anchor overstates how cheap it looks. Analysts target $16–$55. Not investment advice.
One valuation read at a 12-month horizon, plus how price compares to peers and the company's own history.
The price sits about 61% below a flat-multiple fair value, while analysts forecast about 12% growth — below our forecast. This describes what's priced in, not a forecast of the move.
TTM earnings are negative, so the read leans on sales- and cash-flow-based methods rather than P/E. This is a data condition, not a forward call.
Score 100 = cheapest in the cohort, 0 = richest. Bars are filled left-to-right based on the peer-relative score (or PEG/self-history where shown).
Each method's implied share price per horizon. Provisional rows use a projected (historical-CAGR) growth input rather than analyst or management guidance.

A “consensus-then vs. actual-now” overlay is on the way — what our valuation estimate said on a past date versus where the price actually landed.
Not investment advice. Scores describe historical and current data; they are not forecasts of future returns. Consult a licensed advisor before making investment decisions.
A long-thesis check that carries the widest uncertainty of the three horizons.

Direction of the business behind the multiple. Bands are backend reads; trailing-12-month basis.
TTM earnings are negative. P/E-based methods drop out and the estimate leans on sales- and cash-flow-based methods. A data condition, not a forward call.

No fragility gates fired. Regime (Mania) does not concentrate fragility.
For similar setups historically (n=20,154): about 33% saw a 20%+ drawdown, and roughly 76% of those did not recover within the year. These are historical base rates for the cohort, not a forecast of this stock.
Looks cheaper than most peers in the same business.
Self-history needs ~20 months of data.
