NYXH

We rate Nyxoah SA (NYXH) as Avoid with a composite score of 28.8/100 at a current price of $4.29. The stock falls in the bottom quintile of our universe across key quantitative factors, and the multi-factor weakness suggests a high probability of continued underperformance.

The rating is primarily driven by strength in stability (59th percentile) and quality (29th percentile), which together account for the majority of the composite score. Offsetting weakness in value (13th percentile) and momentum (15th percentile) tempers our overall conviction. We assign a No Moat rating (28/100), Medium uncertainty, and Poor capital allocation.

Key items to watch: momentum to confirm whether the current price trend has legs; the path to profitability; valuation compression risk if growth disappoints. Any material change in these dynamics could warrant a reassessment of our rating. The moat trend is widening, which provides additional comfort in the durability of the competitive position.

Nyxoah SA holds a top-quartile position (#0 of 50) within the Manufacturing sector, based on our composite quantitative scoring across quality, value, momentum, and stability factors. The composite score of 28.8/100 places it at rank #4603 in our full 7,333-stock universe. At $229M in market capitalization, Nyxoah SA is a small-cap player in the Manufacturing space, which limits certain scale advantages but may allow for more agile strategic execution.

Revenue contraction of -3% combined with momentum at the 15th percentile paints a cautious picture of the near-term business outlook. The market appears to be pricing in continued challenges, and a catalyst for reversal is not clearly visible from current data.

The margin cascade tells an important story: gross margins of 66% (+23.2pp vs sector) narrow to operating margins of -1301% (-1302.1pp vs sector) and net margins of -1310.2%, yielding a gross-to-net conversion rate of -1995%. The significant margin erosion from gross to net suggests elevated operating expenses, high interest costs, or other structural drags that warrant monitoring.

At a current price of $4.29, Nyxoah SA is trading at a premium to fundamental value. Our value factor score of 13/100 reflects a composite assessment across multiple valuation metrics including price-to-earnings, price-to-book, EV/EBITDA, and price-to-sales ratios relative to both sector peers and the broader market. The premium valuation implies the market is pricing in significant future growth or quality improvements that are not yet fully reflected in current fundamentals.

The stock currently trades at P/B of 1.7x, P/S of 10.5x. We evaluate these multiples in the context of both absolute levels and sector-relative positioning to form our valuation view.

We assign a Medium uncertainty rating to Nyxoah SA. The stock presents a balanced risk profile: current negative profitability (net margin -1310.2%) and weak quality scores (29th percentile). While not risk-free, the core business fundamentals are adequate to withstand moderate economic stress, and the range of potential outcomes around our fair value estimate is manageable.

Specific risk factors that inform our assessment include: current negative profitability (net margin -1310.2%); weak quality scores (29th percentile); low beta of 0.47 — while defensive, this may indicate limited upside participation in bull markets. Each of these factors independently widens the distribution of potential outcomes, and in combination they create a risk profile that demands careful position sizing. The stability factor at the 59th percentile and quality factor at the 29th percentile provide a quantitative summary of the overall risk landscape.

Key risk mitigants include: healthy gross margins of 66% provide a buffer against cost pressures; conservative leverage (2% D/E) limits balance sheet risk. These factors partially offset the identified risks and provide downside protection in adverse scenarios. On balance, the risk-reward profile is favorable for long-term investors.

We rate Nyxoah SA's capital allocation as Poor. Key concerns include low returns on equity (-209.2%), negative profitability, weak asset returns (ROA -149.6%). Exemplary capital allocators generate ROE above 20% and maintain conservative leverage — Nyxoah SA significantly underperforms these benchmarks, raising questions about management's ability to create shareholder value.

Investors should scrutinize management's reinvestment decisions and balance sheet trajectory before committing capital. Poor capital allocation often compounds over time: overlevered balance sheets limit strategic flexibility, while low returns on capital destroy shareholder value. We would need to see sustained improvement in profitability metrics and balance sheet discipline before considering an upgrade.

In summary, Nyxoah SA receives a Avoid rating with a composite score of 28.8/100 (rank #4603 of 7,333). Our quantitative framework assigns a No Moat (28/100, trend: widening), Medium uncertainty, and Poor capital allocation. The average factor score across quality, value, momentum, stability, and investment is 29/100.

Our analysis does not support a constructive view on Nyxoah SA at this time. The combination of limited competitive advantages, medium uncertainty, and poor capital allocation suggests unfavorable risk-reward at current levels. We recommend investors avoid new positions and existing holders consider reducing exposure.
