Why Is Waters Corporation Not Exciting?

We don't have much confidence in Waters Corporation. Here are three reasons why WAT doesn't excite us and a stock we'd rather own.

1. Slow Organic Growth Suggests Waning Demand In Core Business

Investors interested in Research Tools & Consumables companies should track organic revenue in addition to reported revenue. This metric gives visibility into Waters Corporation’s core business because it excludes one-time events such as mergers, acquisitions, and divestitures along with foreign currency fluctuations - non-fundamental factors that can manipulate the income statement.

Over the last two years, Waters Corporation’s organic revenue averaged 2.1% year-on-year growth. This performance slightly lagged the sector and suggests it may need to improve its products, pricing, or go-to-market strategy, which can add an extra layer of complexity to its operations.

2. Shrinking Adjusted Operating Margin

Adjusted operating margin is a key measure of profitability. Think of it as net income (the bottom line) excluding the impact of non-recurring expenses, taxes, and interest on debt - metrics less connected to business fundamentals.

Looking at the trend in its profitability, Waters Corporation’s adjusted operating margin decreased by 13.7 percentage points over the last two years. This raises questions about the company’s expense base because its revenue growth should have given it leverage on its fixed costs, resulting in better economies of scale and profitability. Its adjusted operating margin for the trailing 12 months was 17.1%.

3. New Investments Fail to Bear Fruit as ROIC Declines

A company’s ROIC, or return on invested capital, shows how much operating profit it makes compared to the money it has raised (debt and equity).

We like to invest in businesses with high returns, but the trend in a company’s ROIC is what often surprises the market and moves the stock price. Unfortunately, Waters Corporation’s ROIC has decreased significantly over the last few years. We like what management has done in the past, but its declining returns are perhaps a symptom of fewer profitable growth opportunities.

Final Judgment

Waters Corporation isn’t a terrible business, but it doesn’t pass our bar. That said, the stock currently trades at 21.6× forward P/E (or $311.11 per share). This valuation is reasonable, but the company’s shakier fundamentals present too much downside risk. We're fairly confident there are better stocks to buy right now. We’d recommend looking at the Amazon and PayPal of Latin America.
