PORTLAND, OR – StenTech acquired Pentagon EMS, adding CNC machining, tooling and fixture capabilities to its precision manufacturing platform serving electronics and high-reliability markets.

The deal marks the fifth add-on acquisition since private equity firm Align Capital Partners acquired StenTech in 2022. Financial terms were not disclosed.

Pentagon brings expertise in complex part manufacturing and is based near Portland, Oregon, expanding StenTech’s geographic footprint in the Pacific Northwest. The combined business will support customers across electronics assembly, aerospace, defense, automotive and medical sectors.

StenTech said the acquisition enhances its ability to deliver integrated manufacturing solutions, combining SMT printing technologies with precision machining to improve production control, consistency and throughput.

Pentagon will continue operating under its existing brand while integrating into StenTech’s broader platform. The move reflects ongoing demand for localized, high-precision manufacturing as companies seek to strengthen supply chains and meet stricter performance requirements.
