Why is 5-year revenue CAGR the most predictive ML feature?

In the Screener Small Caps XGBoost model, 5-year revenue CAGR is one of the most important features. The reason: on Euronext Growth small caps, sustained growth over 5 years is hard to maintain by accident — it reflects a real competitive advantage, structural demand, and consistent management execution. All of these factors are predictive of future outperformance.

Revenue Growth: How to Analyse It

Q: How do you calculate revenue CAGR?

The CAGR (Compound Annual Growth Rate) is calculated as follows: CAGR = (final revenue / initial revenue)^(1/number of years) − 1. Example: revenue of €10M in 2021 and €17M in 2026 → CAGR = (17/10)^(1/5) − 1 = 11.2% a year.

Q: What is organic growth?

Organic growth is revenue growth generated by the existing business, excluding acquisitions and currency effects. It measures the company's ability to grow sales by its own means. It is the highest-quality growth signal — a company that grows only through acquisitions, with no organic growth, depends on the availability of targets and on debt.

Q: What revenue growth rate is good for a small cap?

On Euronext Growth, a revenue CAGR above 10% over 3 years is considered solid for a small industrial or services company. For tech or SaaS companies, 20% is often the minimum investors expect. Below 5%, the valuation becomes hard to sustain unless margins are improving sharply.

Q: How are revenue growth and profitability linked?

Revenue growth only has value if it is profitable. Two tests: the NI CAGR / revenue CAGR ratio should be above 1 (profitability growing faster than revenue) and FCF should remain positive during the growth phase. A company that grows fast but burns cash with no prospect of profitability is a trap.

CAGR: measuring growth over several years

Year-on-year (YoY) growth is too volatile to be meaningful — a single good or bad year distorts the picture. The CAGR (Compound Annual Growth Rate) smooths growth over a period to give an average annual rate:

CAGR = (final revenue / initial revenue)^(1/n) − 1

Where n is the number of years. On Euronext Growth, the most useful windows are the 3-year CAGR (recent trend) and the 5-year CAGR (long-term signal — the most predictive according to the ML model).

5-year revenue CAGR: a major feature in the ML model
Among the features used by the XGBoost model, revenue_cagr_5y is one of the most predictive of 12-month outperformance. Sustained growth over 5 years is no accident — it reflects a structural competitive advantage that is hard to challenge.

Organic growth vs acquisition-led growth

Revenue that triples in 3 years can hide two very different realities:

Organic growth: the company sells more to new customers or raises prices — a sign of structural demand and competitiveness
Acquisition-led growth: the company buys competitors or adjacent markets — its valuation depends on the quality of the acquisitions and the level of debt

The distinction is crucial for valuation. On Euronext Growth, ask yourself: if the company stopped acquiring, how fast would it grow naturally? That is its true organic pace.

The 4 dimensions of growth quality

🔄

Recurrence

What share of revenue is recurring (subscriptions, contracts, maintenance) vs one-off (projects, single orders)? Recurrence provides visibility and reduces volatility.

💰

Profitability of growth

NI CAGR / revenue CAGR > 1 → profitability grows faster than revenue. Below 1, growth dilutes margins — a situation to watch.

💵

Cash conversion

Positive FCF during the growth phase. If working capital grows as fast as revenue, the company is "funding" its growth through customers who have not yet paid — a liquidity risk.

📊

Consistency across segments

Is growth driven by all segments or just one? Concentration on a single customer or segment undermines durability.

Guidance-driven growth vs real growth
Always compare the outlook announced at the start of the year with what was actually delivered by year-end. Over 3 years, a management team that meets its growth commitments is a sign of management quality — and of real visibility into its market.

Reference thresholds by small-cap profile

Expectations vary with the sector and the stage of development:

Industrials / Manufacturing: 3-year CAGR > 8% = solid, > 15% = strong, > 25% = exceptional
B2B services: 3-year CAGR > 10% = solid, > 20% = strong
Tech / SaaS: 3-year CAGR > 20% expected, < 15% = a sign of slowdown
Retail: 3-year CAGR > 5% = solid in this thin-margin sector

Growth generated by the existing business, excluding acquisitions and currency effects. It is the highest-quality signal — a company that grows only through acquisitions, with no organic growth, depends on the availability of targets and on debt.

What revenue growth rate is good for a small cap?▾

On Euronext Growth: > 10% 3-year CAGR is solid for an industrial or services company. For tech/SaaS, 20% is often the minimum expected. Below 5%, the valuation is hard to sustain.

How are revenue growth and profitability linked?▾

Growth only has value if it is profitable. Check that NI CAGR / revenue CAGR > 1 (profitability growing faster than revenue) and that FCF stays positive during the growth phase.

Why is 5-year revenue CAGR the most predictive ML criterion?▾

In the XGBoost model, revenue_cagr_5y is one of the most predictive features. Sustained growth over 5 years reflects a structural competitive advantage, stable demand and consistent management execution — all predictive of future outperformance.
