Insufficient price history to assess momentum. Score defaulted to neutral (50).

PHE scores 28/100 for profitability, assessed sector-relative on margins and via absolute thresholds for capital efficiency. Gross margin of 57.8% is 29% above the sector average of 45% — indicating margins are materially above peers. The company is currently loss-making with a net margin of -942.1%. FCF conversion of 0% is low — reported earnings may overstate true cash generation. Overall, profitability metrics are weaker across multiple model inputs. Profitability trends can change and should be reviewed alongside balance-sheet risk.

PHE received a valuation score of 56/100 using sector-relative scoring. Its Forward P/E of 60.2x is 235% above the sector average of 18x. EV/EBITDA of -0.7x sits 106% below the sector norm of 12x. Overall, valuation multiples are broadly in line with selected sector references. Valuation metrics are not forecasts of future returns.

PHE has a financial solvency risk score of 37/100. This shows lower leverage risk and a relatively healthy balance sheet. Interest coverage of -426.5x means earnings comfortably exceed debt service. Current ratio of 4.99x confirms strong short-term liquidity. The company appears to have flexibility to invest, return capital, or absorb unexpected shocks.

PHE scores 94/100 for operational quality, indicating high operational risk. Key concerns: a negative net margin of -942.1% — the company is loss-making; negative FCF (-630.6% FCF margin) — the business is cash burning; weak capital efficiency with -41.5% Cash ROA; significant margin instability of ±6636.2pp over 3 years — the primary risk driver here. These weaknesses make the business vulnerable to cost shocks or revenue shortfalls. Monitor profitability trends closely.

PHE has a volatility risk score of 95/100. This indicates elevated price instability in the measured period. Beta of 2.01 means it moves 2.01x the market on average. High volatility can increase drawdown risk and may require tighter risk controls, depending on an investor's objectives and risk tolerance.

PHE has a market cap of £0.0B (Nano Cap), resulting in a size risk score of 80/100. As a smaller company, it faces elevated business and funding risk. Small and micro-caps have higher failure rates, less diversified revenue, and greater vulnerability to competitive threats or economic shocks. They often lack scale advantages and may struggle to access capital markets during stress. Smaller companies can experience higher dispersion of outcomes, including business failure or sustained capital impairment. Diversification is important when investing at this size.
