Revenue Growth

A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years.

With $21.6 billion in revenue over the past 12 months, ADP is a behemoth in the business services sector and benefits from economies of scale, giving it an edge in distribution. This also enables it to gain more leverage on its fixed costs than smaller competitors and the flexibility to offer lower prices.

As you can see below, ADP grew its sales at a solid 8.1% compounded annual growth rate over the last five years. This is a good starting point for our analysis because it shows ADP’s demand was higher than many business services companies.

We at StockStory place the most emphasis on long-term growth, but within business services, a half-decade historical view may miss recent innovations or disruptive industry trends. ADP’s annualized revenue growth of 6.9% over the last two years is below its five-year trend, but we still think the results were respectable.

This quarter, ADP reported year-on-year revenue growth of 7%, and its $5.94 billion of revenue exceeded Wall Street’s estimates by 1.5%.

Looking ahead, sell-side analysts expect revenue to grow 5.3% over the next 12 months, a slight deceleration versus the last two years. We still think its growth trajectory is satisfactory given its scale and indicates the market is forecasting success for its products and services.

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.

ADP has been a well-oiled machine over the last five years. It demonstrated elite profitability for a business services business, boasting an average adjusted operating margin of 21.9%.

Analyzing the trend in its profitability, ADP’s adjusted operating margin decreased by 10.8 percentage points over the last five 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.

This quarter, ADP generated an adjusted operating margin profit margin of negative 23%, down 52.4 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 sales through excessive spending on advertising and promotions.

ADP’s EPS grew at 12.5% compounded annual growth rate over the last five years, higher than its 8.1% annualized revenue growth. However, this alone doesn’t tell us much about its business quality because its adjusted operating margin didn’t improve.

Diving into the nuances of ADP’s earnings can give us a better understanding of its performance. A five-year view shows that ADP has repurchased its stock, shrinking its share count by 5.9%. This tells us its EPS outperformed its revenue not because of increased operational efficiency but financial engineering, as buybacks boost per share earnings.

Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.

For ADP, its two-year annual EPS growth of 9.4% was lower than its five-year trend. This wasn’t great, but at least the company was successful in other measures of financial health.

In Q1, ADP reported adjusted EPS of $3.37, up from $3.06 in the same quarter last year. This print beat analysts’ estimates by 2.3%. Over the next 12 months, Wall Street expects ADP’s full-year EPS of $10.74 to grow 9.5%.

Key Takeaways from ADP’s Q1 Results

It was good to see ADP narrowly top analysts’ revenue expectations this quarter. We were also glad its EPS outperformed Wall Street’s estimates. Overall, this print had some key positives. The stock traded up 1.4% to $201.93 immediately after reporting.

Indeed, ADP had a rock-solid quarterly earnings result, but is this stock a good investment here?
