Revenue growth
A company’s long-term performance is an indicator of its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Waters Corporation’s revenue grew at a solid 15.4% compounded annual growth rate over the last five years. Its growth beat the average healthcare company and shows its offerings resonate with customers.

Long-term growth is the most important, but within healthcare, a half-decade historical view may miss new innovations or demand cycles. Waters Corporation’s annualized revenue growth of 39% over the last two years is above its five-year trend, suggesting its demand was strong and recently accelerated. 
Analyzing the company’s organic revenue helps clarify its revenue dynamics by stripping out one-time events like acquisitions and currency fluctuations that don’t accurately reflect its fundamentals. Over the last two years, Waters Corporation’s organic revenue averaged 8.3% year-on-year growth. Total revenue growth outpaced organic growth over that period, indicating that some combination of acquisitions and foreign exchange rates boosted its headline results. 
This quarter, Waters Corporation reported year-on-year revenue growth of 121%, and its $1.77 billion of revenue beat Wall Street’s consensus estimates by 0.7%. Management is guiding for a 94.1% year-on-year increase in revenue next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 24.6% over the next 12 months, according to S&P, a deceleration versus the last two years. Despite the slowdown, this projection is noteworthy and implies the market expects its products and services to succeed.
Adjusted operating margin
Waters Corporation has been an efficient company over the last five years. It was one of the more profitable businesses in the healthcare sector, with an average adjusted operating margin of 27.5%.
Looking at the trend in its profitability, Waters Corporation’s adjusted operating margin decreased by 8.7 percentage points over the last five years. The company’s two-year trajectory also shows it failed to return to peak profitability as its margin fell by 9.5 percentage points. This was a poor performance, showing that its expenses were rising and it couldn’t pass those costs on to its customers.

In Q3, Waters Corporation generated an adjusted operating margin of 8.5%, down 21.8 percentage points year on year. This contraction shows it was less efficient because its expenses grew faster than its revenue.
Earnings per share
Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth. For example, a company could inflate its revenue through excessive spending on advertising and promotions.
Waters Corporation’s EPS grew at a decent 5.1% compounded annual growth rate over the last five years. However, this performance trailed its 15.4% annualized revenue growth, indicating the company became less profitable on a per-share basis as it expanded.

A closer look at Waters Corporation’s earnings helps explain its performance. As noted earlier, Waters Corporation’s adjusted operating margin declined by 8.7 percentage points over the last five years. Its share count also grew by 59.4%, meaning the company not only became less efficient with its operating expenses but also diluted its shareholders. 
In Q3, Waters Corporation reported adjusted EPS of $4.10, up from $3.40 in the same quarter last year. This result beat analysts’ consensus estimates by 2.6%. Over the next 12 months, Wall Street expects Waters Corporation’s full-year EPS to grow 10.9% from $14.38 to $15.95, according to S&P.
Key takeaways from Waters Corporation’s Q3 results
