Proto Labs Inventory

Proto Labs posts a inventory of $15M as of June 2026. That compares with $13M in the prior-year period — up 17.0% year over year. Comparing that reading with peers and prior periods is usually more useful than looking at the number in isolation.

In the prior comparable period, Proto Labs's inventory was $13M. The latest reading is $15M — a 17.0% year-over-year increase (period ending June 2026). Use the history and growth charts on this page for a longer lookback.

Inventory is one piece of Proto Labs's financial statement story. At $15M, it should be interpreted next to related metrics — for example revenue with costs, assets with liabilities, or income with margins. Stockcircle links those related pages so you can move from this number to the surrounding context quickly.

Context for PRLB's inventory usually means three checks: (1) trend versus prior periods, (2) level versus peers, and (3) consistency with growth and profitability. This page covers the first two; Proto Labs's other metric pages and overview cover the third.

Judging Proto Labs against Technology peers is usually better than using a market-wide rule of thumb. Business models inside Technology are more comparable, which makes gaps in inventory easier to interpret. Start with $15M here, then scan peer and history charts to see if the gap is persistent.
