About Porter Corp

Porter Corp, a for-profit manufacturer based in Holland, Michigan, supplies prefabricated metal structures, refrigeration equipment, and portable buildings to federal agencies predominantly as a prime contractor (97% of recent awards), competing under Small Business set-asides. The vendor operates across a fragmented customer base spanning the Department of Defense, the Department of the Interior, the General Services Administration, and the Department of Homeland Security, with no dominant agency relationship.

Porter's capability portfolio centers on prefabricated metal building components, portable structures, and refrigeration equipment — concrete product lines reflected in NAICS concentration around Prefabricated Metal Building and Component Manufacturing and Sporting and Athletic Goods Manufacturing (10 awards each) and PSC concentration around Refrigeration Equipment (18 awards) and Prefabricated and Portable Buildings (15 awards). Representative work includes a $27.2 thousand purchase order from the Department of Interior Fish and Wildlife Service Region 6 for a Tennessee National Wildlife Refuge polygon structure (awarded September 2021) and a sub engagement with RJS Construction Inc. for Long Lake National Wildlife Refuge multi-purpose structural insulated panels (awarded June 2024). The vendor also subcontracts with McCarthy Hitt — Next NGA West Joint Venture on pre-engineered structure work including walkway canopies for the St. Louis design-build project.

Customer concentration is low across both award count and dollar value. The top five customers by award count account for 44% of awards, led by the Department of the Army (16 awards), while the top five by potential value account for 55%, led by the GSA Federal Acquisition Service ($200 thousand). The two rankings diverge markedly — the Air Force carries substantial dollars ($117 thousand) relative to its award count (4), while the Army dominates volume but carries minimal dollars per award. Porter holds positions on five parent vehicles, notably the Federal Supply Schedule GS07F5940P (9 task orders, $108 thousand combined potential value) and several Army Basic Ordering Agreements and Indefinite Delivery Contracts.

Activity is sporadic: one award in 2024, two in 2021, three in 2018, with no recorded awards in the intervening years. The combined potential value across all 63 awards totals $944 thousand, but obligated dollars reach $8.3 million — indicating that Porter's actual invoiced revenue substantially exceeds contract ceilings, likely reflecting indefinite-delivery mechanism dynamics and repeat orders over decades. The vendor's first recorded award dates to 1982, suggesting decades of federal supply relationships, though recent award frequency is low and irregular.
