We’re glad investors have benefited from the price increase, but we're swiping left on Allegro MicroSystems for now. Here are three reasons why there are better opportunities than ALGM and a stock we'd rather own.
Why Do We Think Allegro MicroSystems Will Underperform?
The result of a spinoff from Sanken in Japan, Allegro MicroSystems (NASDAQ:ALGM) is a designer of power management chips and distance sensors used in electric vehicles and data centers.
1. Long-Term Revenue Growth Disappoints
A company’s long-term sales performance can indicate its overall quality. Any business can have short-term success, but a top-tier one grows for years. Over the last five years, Allegro MicroSystems grew its sales at a tepid 5.1% compounded annual growth rate. This was below our standard for the semiconductor sector. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.
2. EPS Trending Down
We track the long-term change in earnings per share (EPS) because it highlights whether a company’s growth is profitable.
Sadly for Allegro MicroSystems, its EPS declined by 19.8% annually over the last five years while its revenue grew by 5.1%. This tells us the company became less profitable on a per-share basis as it expanded.

3. Free Cash Flow Margin Dropping
Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.
As you can see below, Allegro MicroSystems’s margin dropped by 9.4 percentage points over the last five years. This along with its unexciting margin put the company in a tough spot, and shareholders are likely hoping it can reverse course. If the trend continues, it could signal it’s becoming a more capital-intensive business. Allegro MicroSystems’s free cash flow margin for the trailing 12 months was breakeven.

Final Judgment
We cheer for all companies solving complex technology issues, but in the case of Allegro MicroSystems, we’ll be cheering from the sidelines. With its shares topping the market in recent months, the stock trades at 49.6× forward price-to-earnings (or $24.11 per share). This valuation tells us a lot of optimism is priced in - we think there are better investment opportunities out there. Let us point you toward the Amazon and PayPal of Latin America.
