What the market price implies · Reverse DCF

To support a price of $30.36, this model requires revenue to grow by 40.28%/yr over the next 10 years, compounded annually.

Historical revenue grew by 13.68%/yr over the past 4 years. The required annual growth rate is 26.60 percentage points higher.

Selected forecast · Base scenario

9.48%/yr · actual 10-year annualized revenue growth

Year 1 growth: 14.85%

Market-implied · Base operating assumptions + edited margins

40.28%/yr · flat 10-year annualized revenue growth

Reverse DCF solves revenue growth itself using Base operating assumptions and your edited margins. Changing forecast growth alone does not change the implied rate. This is a model-implied requirement, not an analyst forecast.

Why this method?

There is not a stable run of positive FCFF to anchor a direct cash-flow CAGR, so the model should start from revenue and margin assumptions instead.

Is FCFF positive and has it been for 3+ consecutive years? Latest FCFF is not positive.

Price vs Fundamentals

Why The Stock Is Moving

Likely multiple compressionHigh confidence

1Y Price: -65.55%Revenue (TTM): 21.96%FCF (TTM): 665.22%P/FCF: 12th pct

What changed

The stock fell 65.55% over the last year. Revenue grew 21.96% over the trailing twelve months. Operating margin moved from -0.22% to 2.18%. Free cash flow grew 665.22% over the trailing twelve months.

What the market seems to be pricing

Visible fundamentals weakened far less than the stock price, and the shares now sit around the 12th percentile of their historical P/FCF range. That looks more like a rerating of the multiple than a collapse in the business.

What would invalidate this read

This read changes if operating margin (currently 2.18%) continues to decline, or if revenue growth turns negative. The bull case requires the business to hold its current trajectory.
