PRLB

Proto Labs is a high-quality, asset-light-ish digital manufacturer with a genuinely fortress balance sheet: $111M cash (+24.4% YoY), only 0.13x liabilities/equity, and a 3.5x current ratio ($234M current assets vs $67M current liabilities). It converts earnings to cash far better than the income statement implies — FY2025 operating cash flow was $74.5M against just $21.2M net income, the gap explained by $33.8M of D&A, and management returned $43M via buybacks (shrinking the share count 1.9%). On a cash basis the stock trades near ~25x EV/OCF, which is defensible for a net-cash compounder; on reported earnings, the 90.7x P/E is not.

The problem is the top line. Revenue has gone $488M → $488M → $504M → $501M → $533M over five years — roughly 2% CAGR with a real (FY2022 -$103M) loss in the middle, likely the Hubs goodwill writedown. FY2025's +6.4% looks like reacceleration, but the MD&A reveals it was driven entirely by mix, not breadth: unique customer contacts FELL 6.1% to 48,415 while revenue per contact rose 13.3% to $11,012. The franchise is getting fewer, bigger orders — good for near-term revenue but a yellow flag on the health of the customer funnel for a business whose moat is supposed to be its mass-market self-serve web platform.
