Company Overview

Pioneering technologies for radio frequency power delivery, Advanced Energy (NASDAQ: AEIS) provides power supplies, thermal management systems, and measurement and control instruments for various manufacturing processes.

Revenue Growth

Reviewing a company’s long-term sales performance reveals insights into its quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Unfortunately, Advanced Energy’s 6.7% annualized revenue growth over the last five years was mediocre. This fell short of our benchmark for the industrials sector and is a poor baseline for our analysis.

Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. Advanced Energy’s annualized revenue growth of 16.3% over the last two years is above its five-year trend, suggesting its demand recently accelerated.

We can better understand the company’s revenue dynamics by analyzing its most important segments, Semiconductor Equipment and Industrial and Medical Equipment, which are 48.5% and 13.9% of revenue. Over the last two years, Advanced Energy’s Semiconductor Equipment revenue (i.e., plasma power) averaged 9.9% year-on-year growth. On the other hand, its Industrial and Medical Equipment revenue (i.e., robotics) averaged 2.2% declines.

This quarter, Advanced Energy reported wonderful year-on-year revenue growth of 30%, and its $574.1 million of revenue exceeded Wall Street’s estimates by 5.6%. Company management is currently guiding for a 38.1% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 23% over the next 12 months, an improvement versus the last two years. This projection is eye-popping and suggests its newer products and services will catalyze better top-line performance.

Operating Margin

Advanced Energy has done a decent job managing its cost base over the last five years. The company has produced an average operating margin of 9.1%, higher than the broader industrials sector.

Looking at the trend in its profitability, Advanced Energy’s operating margin rose by 2.9 percentage points over the last five years, as its sales growth gave it operating leverage.

In Q2, Advanced Energy generated an operating margin profit margin of 16.6%, up 9.4 percentage points year on year. The increase was solid, and because its operating margin rose more than its gross margin, we can infer it was more efficient with expenses such as marketing, R&D, and administrative overhead.

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.

Advanced Energy’s decent 8.4% annual EPS growth over the last five years aligns with its revenue performance. This tells us its incremental sales were profitable.

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

Advanced Energy’s two-year annual EPS growth of 46.8% was fantastic and topped its 16.3% two-year revenue growth.

We can take a deeper look into Advanced Energy’s earnings quality to better understand the drivers of its performance. Advanced Energy’s operating margin has expanded over the last two years. This was the most relevant factor (aside from the revenue impact) behind its higher earnings; interest expenses and taxes can also affect EPS but don’t tell us as much about a company’s fundamentals.

In Q2, Advanced Energy reported adjusted EPS of $2.74, up from $1.50 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 Advanced Energy’s full-year EPS to grow 29.6% from $8.51 to $11.03.

Key Takeaways from Advanced Energy’s Q2 Results

We were impressed by Advanced Energy’s optimistic EPS guidance for next quarter, which blew past analysts’ expectations. We were also excited its adjusted operating income outperformed Wall Street’s estimates by a wide margin. Zooming out, we think this was a good print with some key areas of upside. The stock traded up 10.2% to $327.05 immediately following the results.

Advanced Energy had an encouraging quarter, but one earnings result doesn’t necessarily make the stock a buy. Let’s see if this is a good investment. What happened in the latest quarter matters, but not as much as longer-term business quality and valuation, when deciding whether to invest in this stock.
