Mimir, a Sweden-based investment firm, reported closing its acquisition of Osprey from Sandvik on October 1. The deal was first agreed in May; Osprey now operates as an independent advanced materials company rather than a Sandvik business unit.
Osprey makes gas atomized metal powders, controlled expansion alloys and engineered materials for aerospace, defense, medical technology, energy and manufacturing customers, drawing on what the companies describe as more than 50 years of metallurgical work and a catalog of over 2,000 powder grades.
| Detail | Figure/name |

| Closing date | October 1, 2026 |
| Agreement signed | May 2026 |
| Production sites | Neath, Wales; Sandviken, Sweden |
| Powder grades | 2,000+ |
MonteCap co-invested alongside Mimir, and MonteCap founder Mats Gunnarsson becomes Osprey’s Chairman. Mimir, which has run similar carve-outs since 2017 including defense-tech firm Euroatlas and fintech Everspring, says its model is to buy units from larger corporate groups and run them as standalone companies with faster decision-making than a parent group typically allows.
For customers, Mimir says nothing changes operationally: both production sites keep running, teams stay the same, products come off the same qualified lines to the same specifications, and existing contracts, orders and technical contacts carry over without interruption.
What the announcement does not cover is the purchase price, headcount at either site, or Osprey’s current revenue and production capacity. There’s also no detail yet on whether Mimir plans further investment in equipment or new powder grades, or how this changes Sandvik’s own additive manufacturing supply chain now that it no longer owns its powder source directly.
