Why Is nLIGHT Not Exciting?
Despite the more favorable entry price, we’re cautious about nLIGHT. Here are three reasons we avoid LASR, plus one stock we’d rather own.
1. Long-Term Revenue Growth Disappoints
A company’s long-term performance is an indicator of its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Over the last five years, nLIGHT grew its sales at a sluggish 3.8% compounded annual growth rate. This was below our standard for the industrials sector.

2. Operating Losses Sound the Alarm
Operating margin is an important measure of profitability as it shows the portion of revenue left after accounting for all core expenses — everything from the cost of goods sold to advertising and wages. It’s also useful for comparing profitability across companies with different levels of debt and tax rates because it excludes interest and taxes.
nLIGHT’s high expenses have contributed to an average operating margin of negative 17.6% over the last five years. Unprofitable industrials companies require extra attention because they could get caught swimming naked when the tide goes out. It’s hard to trust that the business can endure a full cycle.

3. Cash Burn Ignites Concerns
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.
While nLIGHT posted positive free cash flow this quarter, the broader story hasn’t been so clean. nLIGHT’s demanding reinvestments have drained its resources over the last five years, putting it in a pinch and limiting its ability to return capital to investors. Its free cash flow margin averaged negative 2.3%, meaning it lit $2.28 of cash on fire for every $100 in revenue.

Final Judgment
nLIGHT isn’t a terrible business, but it doesn’t pass our bar. Following the recent decline, the stock trades at 105× forward P/E (or $39.63 per share). This valuation tells us a lot of optimism is priced in - you can find more timely opportunities elsewhere. We’d suggest looking at the most entrenched endpoint security platform on the market.
