In the search for long-term investment opportunities, many investors turn to the principles of legendary fund manager Peter Lynch. His strategy, famously outlined in One Up on Wall Street, focuses on finding companies with solid, lasting growth that are trading at sensible prices, a philosophy often called Growth at a Reasonable Price (GARP). Lynch supported a disciplined, fundamental method, searching for firms with good financials, controlled debt, and a clear business model an investor can grasp. A central idea is the PEG ratio, which compares a stock's price-to-earnings (P/E) ratio to its earnings growth rate, trying to find value in growth stories. A recent filter built on Lynch's main criteria has identified EXLSERVICE HOLDINGS INC (NASDAQ:EXLS) as a possible candidate for more study.

Meeting the Lynch Criteria
A closer look at ExlService's financial numbers shows good agreement with the quantitative filters taken from Peter Lynch's strategy. The company works in the business process management and analytics field, providing data-led and digital operations services for insurance, healthcare, banking, and other industries, a business that, while not exciting, is necessary and clear.
The filter's main requirements and how EXLS compares are listed below:
- Sustainable Earnings Growth: Lynch preferred companies increasing earnings per share (EPS) between 15% and 30% each year, a range seen as sustainable. ExlService's five-year EPS growth rate of 22.6% fits well within this target zone, showing a record of solid but not excessive increase.
- Sensible Valuation via PEG: The foundation of Lynch's valuation method is the PEG ratio. A number at or below 1.0 implies the stock's price may not completely account for its growth path. ExlService's PEG ratio, based on its past five-year growth, is 0.67, hinting the market may be pricing its historical growth performance too low.
- Strong Profitability (ROE): Return on Equity (ROE) shows how well a company produces profits from shareholder equity. Lynch wanted a minimum of 15%. ExlService's ROE of 27.5% is very strong, almost twice the minimum, pointing to high-quality, profitable growth.
- Financial Health (Debt & Liquidity): A cautious balance sheet was critical for Lynch. The filter demands a Debt-to-Equity ratio below 0.6, with Lynch himself favoring levels under 0.25. ExlService's ratio of 0.32 shows careful use of debt, paid for mainly by equity. Also, its Current Ratio of 2.56 indicates more than enough liquidity to meet short-term bills, well above the filter's need of 1.0.
Fundamental Health Check
Beyond the specific filter settings, a wider fundamental review of ExlService shows a company in good financial condition. According to ChartMill's detailed fundamental report, EXLS gets a high total score of 8 out of 10, placing it well within the competitive IT Services industry.
The report notes excellent scores in both financial health (9/10) and profitability (9/10). The company's solvency is sound, with an Altman-Z score showing no bankruptcy danger and a low debt-to-free-cash-flow ratio. Profitability numbers are consistently high, with returns on assets, equity, and invested capital all in the 90th percentile or better compared to industry peers. Margins have also improved in recent years.
On valuation, the report states EXLS trades at a P/E ratio of 15.24, which is lower than both the wider S&P 500 and most of its industry rivals. While growth is predicted to slow from its very good historical rate, analysts still forecast solid future EPS and revenue growth in the low-to-mid teens percentage range.
A Candidate for Further Research
For investors following a GARP or Peter Lynch-inspired method, ExlService Holdings offers an interesting profile. It joins a history of solid, sustainable earnings growth with a valuation that seems sensible compared to that growth, shown by its low PEG ratio. Its very good profitability and firm balance sheet meet Lynch's focus on financial strength and business durability. The company works in the necessary, though plain, area of business process optimization, a field with long-term demand support from digital change and data analytics.
It is vital to recall that a filter result is a beginning, not an end. Peter Lynch himself highlighted the need to know the business behind the numbers. Interested investors should study ExlService's competitive standing, client focus, and management plan to build a full view.
