Afya (AFYA): A ROCE-Driven Compounding Machine in Brazil's Healthcare Education Sector

The Brazilian education sector has long been a battleground for inefficiency and underinvestment, but Afya Limited (AFYA) is carving out an exception. With a Return on Capital Employed (ROCE) of 14%—surpassing its peers' average of 9.8%—Afya has positioned itself as a rare “compounding machine” in a stagnating industry. Pair this operational efficiency with a 143% surge in its capital base, undervalued multiples, and institutional support, and the case for Afya becomes compelling. For investors seeking high returns in a low-growth market, this could be a once-in-a-cycle opportunity.

ROCE: The Engine of Compounding

ROCE, a measure of profitability relative to capital invested, is the lifeblood of sustainable growth. Afya's ROCE of 14%—a full 42% higher than the sector average—signals exceptional capital allocation. This outperformance stems from two factors:
1. Operational Leverage: Afya's vertically integrated model, combining healthcare education with hands-on clinical training, reduces overhead costs. Its Adjusted EBITDA margin of 44.1% (up 360 basis points year-over-year) underscores this efficiency.
2. Strategic Capital Deployment: The 143% increase in capital employed since 2020 reflects disciplined expansion into high-demand healthcare niches, such as nursing and medical technology. This growth hasn't diluted returns; instead, it has amplified them through economies of scale.

The result? A flywheel effect: higher ROCE attracts capital, which fuels further expansion and profitability. For context, a 14% ROCE means Afya generates 14 cents of profit for every dollar of capital used—a stark contrast to its competitors.

Undervalued Metrics: A Hidden Gem in a Discounted Market

Despite its operational prowess, Afya trades at a discount to its peers. Key metrics highlight this undervaluation:
- P/E Ratio: 13x vs. the sector average of 18x.
- P/B Ratio: 2.07x vs. 2.95x for its competitors.
- 5-Year Stock Performance: A 31% decline, driven largely by macroeconomic headwinds in Brazil and sector-specific regulatory uncertainty.

These metrics suggest the market has yet to price in Afya's structural advantages. Meanwhile, its balance sheet is robust: cash reserves of R$911 million (as of December 2024) and an operating cash conversion ratio of 102.2% ensure it can weather volatility while capitalizing on opportunities.

Institutional Backing and Catalysts Ahead

Afya's 88% institutional ownership—a figure that includes prominent global funds—speaks to its credibility. This investor confidence is bolstered by two key catalysts:
1. Brazil's Healthcare Demand Surge: The country's aging population and underpenetrated healthcare sector require an estimated 150,000 new healthcare professionals by 2030. Afya's focus on vocational training positions it to supply this talent pipeline.
2. Regulatory Tailwinds: Recent reforms in Brazil's education sector, including relaxed credit policies for vocational programs, could boost enrollment and margins.

The Investment Case: Act Before Consensus Catches Up

Afya's stock has been a laggard, but its fundamentals suggest a turning point. The combination of high ROCE, underappreciated valuation, and institutional support creates a compelling risk-reward profile. Here's why to act now:
- Mean Reversion Potential: If Afya's P/E expands to the sector average of 18x, its stock could rise by ~38%.
- Sector Outperformance: The healthcare education segment is growing at 8% annually in Brazil—a trend Afya is uniquely placed to dominate.
- Low Risk Profile: Its strong cash flows and low debt (net debt to EBITDA of 0.5x) mitigate downside risks.

Conclusion: A Rare Entry Point for Long-Term Gains

Afya isn't just surviving—it's thriving in a challenging environment. Its ROCE-driven model, undervalued shares, and institutional backing make it a standout pick in a stagnating sector. With Brazil's healthcare needs set to explode and the stock still discounted, this is a rare chance to invest in a compounding machine before the broader market catches on. For investors with a 3–5 year horizon, Afya offers the potential for outsized returns. The question isn't whether to act—it's how soon.
