Last quarter, their 3D printing business grew 11.4% year-over-year and CBC machining, their biggest segment, grew 16.4%, and accounted for nearly half of all revenues. NASA are Raytheon are customers. Aerospace and defence are a quarter of sales. They served slightly fewer customers last quarter than a year ago, but each customer spent 17% more. Recently, they reported Q3 revenues up 14% YOY, a company record, beating estimates. Adjust earnings also beat. PRLB projects 10-11% sales growth this year, up from 8-10%, ahead of Wall Street forecasts. However, adjusted EBITDA missed while adjusted gross margins were light. Shares have fallen since then, down 26% the past month but still up 36.5% this year. Rising costs have squeezed margins. It trades at over 30x PE, but grows in single digits only, so it's rich. They have cash flow and no doubt, though. This is a speculative stock.
