Company Overview

Founded during the dot-com era in 1999 and specializing in high-intent consumer traffic, QuinStreet (NASDAQ: QNST) operates digital performance marketplaces that connect clients in financial and home services with consumers actively searching for their products.

Revenue Growth

Reviewing a company’s long-term sales performance reveals insights into its quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years.

With $1.29 billion in revenue over the past 12 months, QuinStreet is a mid-sized business services company, which sometimes brings disadvantages compared to larger competitors benefiting from better economies of scale. On the bright side, it can still flex high growth rates because it’s working from a smaller revenue base.

As you can see below, QuinStreet’s 17.5% annualized revenue growth over the last five years was incredible. This is a great starting point for our analysis because it shows QuinStreet’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. QuinStreet’s annualized revenue growth of 45.2% over the last two years is above its five-year trend, suggesting its demand was strong and recently accelerated.

This quarter, QuinStreet reported magnificent year-on-year revenue growth of 42.7%, and its $373.9 million of revenue beat Wall Street’s estimates by 4%. Company management is currently guiding for a 31.2% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 12% over the next 12 months, a deceleration versus the last two years. Despite the slowdown, this projection is commendable and indicates the market is forecasting success for its products and services.

Adjusted Operating Margin

QuinStreet was roughly breakeven when averaging the last five years of quarterly operating profits, one of the worst outcomes in the business services sector.

On the plus side, QuinStreet’s adjusted operating margin rose by 4.3 percentage points over the last five years, as its sales growth gave it operating leverage.

This quarter, QuinStreet generated an adjusted operating margin profit margin of 7.8%, up 6.4 percentage points year on year. This increase was a welcome development and shows it was more efficient.

Earnings Per Share

We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.

QuinStreet’s EPS grew at a spectacular 14% compounded annual growth rate over the last five years. Despite its adjusted operating margin improvement during that time, this performance was lower than its 17.5% annualized revenue growth, telling us that non-fundamental factors such as interest and taxes affected its ultimate earnings.

Diving into QuinStreet’s quality of earnings can give us a better understanding of its performance. A five-year view shows QuinStreet has diluted its shareholders, growing its share count by 4.4%. This dilution overshadowed its increased operational efficiency and has led to lower per share earnings. Taxes and interest expenses can also affect EPS but don’t tell us as much about a company’s fundamentals.

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

For QuinStreet, its two-year annual EPS growth of 256% was higher than its five-year trend. We love it when earnings growth accelerates, especially when it accelerates off an already high base.

In Q2, QuinStreet reported adjusted EPS of $0.50, up from $0.25 in the same quarter last year. This print easily cleared analysts’ estimates, and shareholders should be content with the results. Over the next 12 months, Wall Street expects QuinStreet’s full-year EPS to grow 21.3% from $1.27 to $1.54.

Key Takeaways from QuinStreet’s Q2 Results

We were impressed by QuinStreet’s optimistic revenue guidance for next quarter, which blew past analysts’ expectations. We were also glad its EPS outperformed Wall Street’s estimates. Zooming out, we think this was a solid print. The stock traded up 28% to $19.47 immediately after reporting.

QuinStreet put up rock-solid earnings, but one quarter doesn’t necessarily make the stock a buy. Let’s see if this is a good investment. When making that decision, it’s important to consider its valuation, business qualities, as well as what has happened in the latest quarter.
