Why Do We Think Magnachip Will Underperform?
We're swiping left on Magnachip for now. Here are three reasons we avoid MX and a stock we'd rather own.
1. Revenue Spiraling Downwards
Examining a company’s long-term performance can provide clues about its quality. Any business can have short-term success, but a top-tier one grows for years. Magnachip’s demand was weak over the last five years as its sales fell at a 18.8% 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. 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, Magnachip’s margin dropped by 42 percentage points over the last five years. Almost any movement in the wrong direction is undesirable because it is already burning cash. If the trend continues, it could signal it’s becoming a more capital-intensive business. Magnachip’s free cash flow margin for the trailing 12 months was negative 30.3%.
3. Short Cash Runway Exposes Shareholders to Potential Dilution
As long-term investors, the risk we care about most is the permanent loss of capital, which can happen when a company goes bankrupt or raises money from a disadvantaged position. This is separate from short-term stock price volatility, something we are much less bothered by.
Magnachip burned through $54.2 million of cash over the last year. With $103.8 million of cash on its balance sheet, the company has around 23 months of runway left (assuming its $46.85 million of debt isn’t due right away).
Unless the Magnachip’s fundamentals change quickly, it might find itself in a position where it must raise capital from investors to continue operating. Whether that would be favorable is unclear because dilution is a headwind for shareholder returns.
We remain cautious of Magnachip until it generates consistent free cash flow or any of its announced financing plans materialize on its balance sheet.
Final Judgment
We cheer for all companies solving complex technology issues, but in the case of Magnachip, we’ll be cheering from the sidelines. That said, the stock currently trades at $3.10 per share (or a forward price-to-sales ratio of 0.6×). The market typically values companies like Magnachip based on their anticipated profits for the next 12 months, but it expects the business to lose money. We also think the upside isn’t great compared to the potential downside here - there are more exciting stocks to buy. We’d recommend looking at one of Charlie Munger’s all-time favorite businesses.
