Why do we think Kulicke and Soffa will underperform?

Even with the cheaper entry price, we’re sitting this one out for now. Here are three reasons why KLIC doesn’t excite us, plus one stock we’d rather own.

1. Revenue spiraling downwards

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. Kulicke and Soffa struggled to consistently generate demand over the last five years as its sales dropped at a 4.7% annual rate. This was below our standards and signals it’s a low quality business. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.

2. Shrinking operating margin

Operating margin is one of the best measures of profitability because it tells us how much money a company takes home after procuring and manufacturing its products, marketing and selling those products, and most importantly, keeping them relevant through research and development.

Analyzing the trend in its profitability, Kulicke and Soffa’s operating margin decreased by 19.5 percentage points over the last five years. Kulicke and Soffa’s performance was poor no matter how you look at it - it shows that costs were rising and it couldn’t pass them onto its customers. Its operating margin for the trailing 12 months was 13.2%.

3. Free cash flow margin dropping

If you’ve followed StockStory for a while, you know we emphasize free cash flow. Why, you ask? We believe that in the end, cash is king, and you can’t use accounting profits to pay the bills.

As you can see below, Kulicke and Soffa’s margin dropped by 18.1 percentage points over the last five years. This along with its unexciting margin puts the company in a tough spot, and shareholders are likely hoping it can reverse course. If the trend continues, it could signal it’s in the middle of a big investment cycle. Kulicke and Soffa’s free cash flow margin for the trailing 12 months was 4.2%.

Final judgment

Kulicke and Soffa doesn’t pass our quality test. Following the recent decline, the stock trades at 13.9× forward P/E (or $72.89 per share). This valuation tells us it’s a bit of a market darling with a lot of good news priced in - you can find more timely opportunities elsewhere. We’d suggest looking at the most dominant software business in the world.
