SkyWater Technology, Inc. is a registered legal entity registered in United States under 1114223600021, and its current status with Minnesota Secretary of State is inactive. The company was incorporated on 28 October 2019 and lists its registered address as STREETBLOOMINGTON, United States. 2 shareholders are on record for SkyWater Technology, Inc., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Minnesota Secretary of State and was last updated on 3 October 2026.

Shareholders

2

Two shareholders are currently on record for SkyWater Technology, Inc., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.

The largest of these is Vanguard Group Inc, holding 12% — the largest recorded stake — followed by BAILLIE GIFFORD & CO at 8.5%.

Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers

5

The Ceo & Director of SkyWater Technology, Inc. currently on record is Thomas J. Sonderman; five officers are currently on record for SkyWater Technology, Inc., filed with Minnesota Secretary of State.

The register reports 13 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Management authority at SkyWater Technology, Inc. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.

The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.

Group Structure

SkyWater Technology, Inc. has no recorded parent company — it sits at the top of its own group structure, with 3 subsidiaries recorded beneath it across 1 jurisdiction. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.

Those 3 subsidiaries span United States jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
