What Do These Terms Mean?
- EPS (Earnings Per Share):
- Quarterly profit divided by the total share count — how much of the profit works out to a single share.
- YoY (Year over Year):
- Change versus the same quarter a year ago — this is how you compare without seasonal distortion (e.g. the holiday shopping season).
- Sales:
- All revenue for the quarter, before any costs are deducted — the top line of the income statement.
- Net Margin:
- What percentage of sales is left over as profit in the end. Negative means the company is posting a loss.
- OCF (Operating Cash Flow):
- The cash that actually flows into the till from the core business during the quarter — harder to dress up than book profit.
- FCF (Free Cash Flow):
- Operating cash flow minus capital expenditures — the money that's genuinely free to use, say for paying down debt, buybacks, or dividends.

Combined picture of the price targets and recommendations of every analyst covering the stock. Price targets are expectations for the next 12 months, not promises — and they often follow the price rather than predict it.
Valuation
What is priced in?
Instead of guessing what the stock is worth, we turn the question around: what free cash flow growth has to happen for today’s market value to add up? The assumptions behind it can be moved.
Today’s market value implies roughly 0.7% growth in free cash flow per year over ten years (assumptions: discount rate 10.0%, terminal growth 2.5%).
| Free cash flow (last twelve months) | $425.0M |
|---|---|
| Market cap | $5.10B |
| Free cash flow in year ten | $455.4M |
| Terminal value as a share of market value | 47.1% |
It shows which assumption is built into today’s price, not whether that assumption will hold. Every assumption can be changed with the sliders; the figures move with them.
A simplified model calculation — not a forecast and not a recommendation.
