Revenue Growth

A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Thankfully, Lam Research’s 12.9% annualized revenue growth over the last five years was impressive. Its growth beat the average semiconductor company and shows its offerings resonate with customers, a helpful starting point for our analysis. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.

We at StockStory place the most emphasis on long-term growth, but within semiconductors, a half-decade historical view may miss new demand cycles or industry trends like AI. Lam Research’s recent performance shows its demand has slowed significantly as its annualized revenue growth of 2.8% over the last two years was well below its five-year trend.

This quarter, Lam Research reported wonderful year-on-year revenue growth of 33.6%, and its $5.17 billion of revenue exceeded Wall Street’s estimates by 3.3%. Beyond the beat, this marks 5 straight quarters of growth, implying that Lam Research is in the middle of its cycle - a typical upcycle generally lasts 8-10 quarters. Company management is currently guiding for a 24.8% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 2.8% over the next 12 months, similar to its two-year rate. This projection doesn't excite us and implies its newer products and services will not accelerate its top-line performance yet. At least the company is tracking well in other measures of financial health.

Here at StockStory, we certainly understand the potential of thematic investing. Diverse winners from Microsoft (MSFT) to Alphabet (GOOG), Coca-Cola (KO) to Monster Beverage (MNST) could all have been identified as promising growth stories with a megatrend driving the growth. So, in that spirit, we’ve identified a relatively under-the-radar profitable growth stock benefiting from the rise of AI, available to you FREE via this link.

Product Demand & Outstanding Inventory

Days Inventory Outstanding (DIO) is an important metric for chipmakers, as it reflects a business’ capital intensity and the cyclical nature of semiconductor supply and demand. In a tight supply environment, inventories tend to be stable, allowing chipmakers to exert pricing power. Steadily increasing DIO can be a warning sign that demand is weak, and if inventories continue to rise, the company may have to downsize production.

This quarter, Lam Research’s DIO came in at 152, which is 9 days below its five-year average. At the moment, these numbers show no indication of an excessive inventory buildup.

Key Takeaways from Lam Research’s Q2 Results

We were impressed by Lam Research’s strong improvement in inventory levels. We were also excited its EPS outperformed Wall Street’s estimates by a wide margin. Looking ahead, revenue and EPS guidance for next quarter also exceeded expectations. Zooming out, we think this quarter featured some important positives. The stock remained flat at $98.25 immediately after reporting.
