What Shimmick Construction does

Shimmick Corporation (NASDAQ: SHIM) is a U.S. heavy civil general engineering contractor headquartered in Irvine, California, delivering complex infrastructure for public-sector clients across water resources, sustainable transportation, energy transition, and climate resilience. The company traces its heritage over 100 years through Washington Construction and Washington Group International, operated as the civil construction division of AECOM until regaining independent status on January 4, 2021 via an investment from Oroco Capital. Shimmick self-performs approximately 80% of project work through its 900+ skilled professionals and operates specialty units including Legacy Foundations (drilled shafts, deep foundations, micro-piles) and Axia Electric LLC (electrical/SCADA, launched June 2025 with $380M+ in electrical work under contract). Notable proprietary methods include the bulk bag cofferdam innovation, record 12-ft diameter CIDH pile drilling, frozen clay heating for levee repair, and integration of advanced multi-stage water purification (ozonation, biological activated carbon, membrane filtration, reverse osmosis, UV advanced oxidation) — exemplified by the $356M North City Pure Water Facility producing 30 MGD for the City of San Diego.

Shimmick's revenue model centers on hard-bid and alternative-delivery (CMGC, Design-Build, Progressive Design-Build, P3) construction contracts with federal, state, and municipal agencies, supplemented by long-duration Operations & Management contracts (tolling operations, customer service centers, fleet overhaul — WSDOT Good To Go!, CFX, Miami-Dade). The company pursues mega-projects through joint ventures (Shimmick-Parsons, Shimmick Obayashi, Myers-Shimmick, Nova-Shimmick, HART Honolulu JV at $874.75M). ENR ranks it #1 in Dams and Reservoirs, #3 in Water Supply, and #27 in Domestic Heavy Contractors. The 2025 financial profile was $492.84M revenue with a $25.58M net loss, but Q1 2026 marked the third consecutive quarter of positive adjusted EBITDA on $88M revenue, with backlog at a record $944M and 2026 guidance of $550M-$600M revenue and $15M-$30M adjusted EBITDA.

Customer concentration is exclusively public-sector (USACE, LA Metro, City of San Diego, Sound Transit, Port of LA, etc.), exposing Shimmick to appropriations cycles but also to the IIJA and IRA infrastructure funding tailwinds. In May 2026, the U.S. Army Corps of Engineers terminated Shimmick's contract on the Chickamauga Lock replacement project (183 workers affected via WARN notice), which the company is appealing — a meaningful execution-risk signal offset by the broader backlog recovery, new COO Sarah Tacker appointment, and Axia Electric verticalization.
