How to Analyse a European Growth Stock: Step-By-Step for 2026

If you want to know how to analyse European growth stocks in 2026, you’re in the right place. This guide breaks down the process into clear, actionable steps using real EUR-based examples and platforms accessible to European investors. We’ll walk through a worked example using Adyen NV (AMS: ADYEN), a leading Dutch fintech company, to illustrate each stage. You’ll finish with a practical understanding—and a checklist you can apply to any European growth stock.

Step 1: Define What Makes a “Growth Stock” in Europe

What to do: Before diving into analysis, clarify what you’re looking for. A European growth stock is typically a company listed on a European exchange (like Euronext, Xetra, or SIX Swiss Exchange) with:

• Revenue growth significantly above the market average (e.g., 15%+ per year)
• Reinvestment of earnings into expansion, not dividends
• Scalable business model and large addressable market

Why it matters: Growth stocks behave differently from value or dividend stocks. Their high valuations are justified by future earnings potential. If you don’t define your target, you risk comparing apples to oranges.

What can go wrong: Confusing a cyclical or recovering company for a true growth stock. Always check that growth is structural, not just a short-term rebound.

Step 2: Gather Key Financial Data

What to do: Collect the company’s recent financials. For Adyen, go to the Adyen Investor Relations page and download the latest annual report. Alternatively, use Simply Wall St for a summary.

• Revenue (total sales)
• Net income (profit after tax)
• Operating margin and net profit margin
• Return on Invested Capital (ROIC)
• Debt levels and cash position

Why it matters: Growth is about more than just sales. You want to see profitable growth, efficient reinvestment, and manageable debt.

What can go wrong: Relying on outdated or incomplete data. Always use the latest annual or quarterly report, and double-check figures from third-party sites.

Step 3: Analyse Revenue Growth and Margins

What to do: Look at the historical revenue growth rate over 3–5 years. For Adyen, you’ll see (as of 2025):

• 2021 Revenue: €1.0bn
• 2022 Revenue: €1.3bn
• 2023 Revenue: €1.6bn
• 2024 Revenue: €2.1bn

Compound annual growth rate (CAGR) ≈ 22% per year.

Check profit margins:

• Operating margin = Operating income / Revenue
• Net margin = Net income / Revenue

For Adyen (2024): Operating margin ≈ 55%, Net margin ≈ 40%

Why it matters: Strong, consistent revenue growth is the hallmark of a growth stock. High margins mean the company is not “buying” growth at the expense of profitability.

What can go wrong: Growth that’s slowing down, or margins that are shrinking due to rising costs or competitive pressure.

Step 4: Evaluate Return on Invested Capital (ROIC)

What to do: Calculate ROIC, which measures how efficiently the company uses its capital to generate profit.

• ROIC = Net Operating Profit After Tax (NOPAT) / Invested Capital

For Adyen (2024):

• NOPAT ≈ €800m
• Invested Capital ≈ €2.5bn
• ROIC ≈ 32%

Why it matters: High ROIC signals that the company is turning investments into profits much better than the average business (typical benchmark: 10–15%).

What can go wrong: Ignoring ROIC can lead you to overpay for companies that grow sales but destroy value due to poor capital allocation.

Step 5: Assess Market Opportunity and Competitive Position

What to do: Read the company’s annual report (usually under “Market Opportunity” or “Business Model” sections) and recent investor presentations.

• How large is the addressable market, in EUR?
• What’s the company’s current market share?
• Who are the main competitors (e.g., Worldline, Nexi for Adyen)?
• What’s the company’s “moat” (e.g., technology, brand, network effects)?

Why it matters: Even the fastest-growing company will plateau if the market is saturated or competitors are catching up. You want a business with “room to run.”

What can go wrong: Overestimating the market size or underestimating competition. Always cross-check management claims with independent industry reports if possible.

Step 6: Analyse Management Quality and Alignment

What to do: Investigate the track record of the CEO and leadership team. On the Adyen website, check the “Our Team” section. Look for:

• Experience in the industry
• Length of tenure
• Insider share ownership (shows “skin in the game”)

On Simply Wall St, find “Insider Transactions” for recent purchases or sales by executives.

Why it matters: Competent, long-term-oriented management significantly increases the odds of sustained growth.

What can go wrong: High executive turnover or large insider share sales may signal trouble ahead.

Step 7: Perform a Valuation in EUR

What to do: Even the best growth stock can be a bad investment at the wrong price. For growth stocks, focus on:

• Price/Earnings to Growth (PEG) ratio: P/E divided by expected growth rate
• Discounted Cash Flow (DCF): Discount future cash flows to present value

For Adyen (mid-2025):

• Share price: €1,080
• 2024 EPS: €18.50
• Forward P/E: 1,080 / 18.50 ≈ 58
• Expected EPS growth next 3 years: 25%/year
• PEG ratio: 58 / 25 ≈ 2.3

On Simply Wall St, use the “Valuation” tab for a quick DCF estimate in EUR. For a manual DCF, assume cash flows grow at 20% per year for 5 years, then 5% terminal growth, and discount at 10%.

Why it matters: Growth stocks often look expensive on current earnings. The PEG ratio and DCF help you judge whether future growth justifies the price.

What can go wrong: Overestimating future growth or using unrealistic discount rates. Always use conservative assumptions.

Step 8: Evaluate Risk and Financial Health

What to do: Examine risk factors in the annual report (look for the “Risk Factors” section). Check:

• Debt/equity ratio (ideally below 1 for growth companies)
• Cash runway (how many months could the company operate if revenue stopped?)
• Currency risk (does the company earn in EUR or other currencies?)
• Regulatory risk (e.g., PSD2, GDPR for fintechs)

Why it matters: Growth stocks are more volatile and can fall hard if growth disappoints. Understanding the risks helps you size your position and set expectations.

What can go wrong: Ignoring regulatory or currency risk, especially for companies with global operations.

Common Mistakes When Analysing European Growth Stocks

• Chasing hype without checking fundamentals: Don’t buy just because everyone is talking about a stock. Work through the steps above to validate the story with numbers.
• Ignoring valuation: Even great companies can be poor investments if you overpay. Always run a PEG or DCF check.
• Overlooking currency and regulatory risks: European stocks can face sudden changes in rules or FX rates, especially if they operate outside the eurozone.
• Failing to monitor growth sustainability: Reassess your thesis quarterly. If growth or margins start to slip, reconsider your position.
• Not diversifying: Concentrating all your capital in one or two growth stocks increases risk. Spread your bets across sectors and geographies.

Next Steps

• Pick one or two European growth stocks from a screener (e.g., on Simply Wall St or Yahoo Finance EU) and apply this process end-to-end.
• Practice reading annual reports and investor presentations—focus especially on the sections covering growth strategy and risks.
• Track your analysis in a spreadsheet, noting key metrics (revenue growth, margin, ROIC, PEG, risks) for future reference.
• Review your thesis every quarter to stay objective and avoid emotional decisions.
