PTGX's valuation appears fair while strong fundamentals support the investment case and forward estimates point to improving growth and profitability, though analyst coverage is limited and estimates vary widely.

Score change since last week

The score fell 9 points, mainly due to valuation and price changes. Price rose 1.0%, from $144.33 to $145.72. Reported EPS was unchanged, so the higher price reduced valuation support.

Valuation and price changes subtracted 8.5 points. The comparison uses the same available inputs on both dates. Displayed changes are rounded to whole points.

Valuation

Estimated operating-earnings valuation: current PE is 207.2x versus 17.1x in comparable estimated history. The model caps earnings at operating profit after interest, assuming proportional tax and per-share effects. This is an estimate, not a verified investment-gain adjustment.

Reported EPS and PE remain in the valuation table. The same estimate is applied to historical earnings and eligible price scenarios. Its contribution to the score is limited by the available evidence; it does not identify all non-recurring items. Comparable history: 29 weeks.

Cash flow & growth

Business trends are strong. Over the past year: revenue +34.8%, operating margin +9.2 percentage points. Free cash flow is 46.9% of revenue. The business score is 86.6/100. Growth, margins and cash generation drive the score. Missing or older data receives less weight.

Favorable scenario

The earnings calculation and the displayed scenario are different.

The earnings case uses $0.89 of EPS and a 167.5× PE, suggesting about $148.46 before the minimum is applied. Valuation history and outlook inform the PE.

The model applies a 15% minimum upside scenario, so the card shows +15%, or about $170.41. That adjusted price does not come from the EPS × PE calculation above.

This is a scenario based on our model, not a forecast or probability.

Downside scenario

Weaker than expected earnings could put pressure on the share price.

Our downside case uses $0.58 of EPS and a 158.1× PE, suggesting a share price of about $92.35 — 39% below today’s price. Valuation history and outlook inform the PE.

This is a scenario based on our model, not a forecast or probability.
