The Holloway Group

What The Holloway Group does

The Holloway Group (legally H.M. Holloway, Inc.) is a privately held, family-owned enterprise founded in 1932 in Lost Hills, California, operating as a parent of affiliated companies across agriculture, environmental services, mining and logistics. Its core businesses include H.M. Holloway's surface gypsum mining (over 2,200 acres owned in fee plus 800 acres leased), Holloway Agricultural Services, LLC (gypsum, compost and custom-blended soil amendments plus agronomy consulting for California growers), Lost Hills Environmental, LLC (a ~301-acre Class III non-hazardous Industrial Waste Landfill sited on reclaimed mine land), and Holloway Logistics, LLC (a private trucking fleet with specialty trailers plus third-party brokerage). Holloway monetizes through quote-based agricultural product sales, per-ton Class III tipping fees from municipalities, government agencies and waste producers, fee-for-service logistics (delivery, in-field spreading and waste back-haul), and agronomy professional services, serving over 700 companies across California's San Joaquin Valley and Central Coast.

In January 2025, Holloway broke ground on a $220 million Materials Recovery Facility (MRF) in Lost Hills as a joint venture with TPI Industries, backed by institutional investor EIG ($24.5B AUM), designed to recover plastics, metals and critical materials from waste streams such as Auto Shredder Residue. The MRF positions Holloway to extend its vertically integrated stack from mining → soil amendments → agronomy → delivery → waste disposal → advanced materials recovery, and is expected to create roughly 50 permanent jobs and hundreds of construction jobs. Holloway is pursuing a March 24, 2026 public meeting on a permit revision to add the MRF, extend the Lost Hills facility's closure date, and modify permitted tonnage and traffic volumes, signaling continued capacity expansion of its environmental franchise. The company remains family-owned after more than 90 years, with executive leadership led by CEO Brian Maxted and operating presence in Lost Hills, Bakersfield and Paso Robles.

Scale indicators8 records

Recent moves10 records

Expansion highlights6 records

Broad incumbents

• USG Corporation (US Gypsum): One of the largest North American gypsum miners and wallboard producers. Comparable because Holloway's core feedstock — surface-mined gypsum in California — feeds the same agricultural and industrial gypsum value chain USG serves at scale.
• National Gypsum Company: Major gypsum mining and wallboard manufacturer with multi-site operations. Comparable as a large, vertically organized gypsum producer whose raw-material extraction parallels Holloway's Lost Hills surface-mining operation.
• Republic Services: One of the largest U.S. solid waste and recycling companies with significant California landfill and MRF operations. Comparable because Republic competes for the same municipal, government, and industrial Class III waste streams that Holloway Environmental accepts at Lost Hills.
• Waste Management, Inc. Largest North American solid waste, recycling, and landfill operator with extensive California footprint. Comparable as a broad incumbent whose Class III landfill, organics, and MRF services overlap with Holloway Environmental's disposal and recovery offering.
• Clean Harbors, Inc. Environmental and industrial services provider offering waste disposal and recycling. Comparable in waste-services scope (including materials recovery) and as a capital-intensive operator that competes for industrial waste volumes.
• Nutrien Ag Solutions: World's largest crop input retailer offering fertilizer, crop protection, and agronomy services to North American growers. Comparable because Nutrien's agronomy-led, custom-blended fertilizer offering competes directly with Holloway Ag for California grower relationships.

Direct peers

• Gypsoil: Specialty agricultural gypsum brand focused on soil amendment sales to U.S. growers. Comparable because Gypsoil targets the same end use — selling gypsum to farmers for soil structure and water management — and competes for shelf and dealer relationships with Holloway Ag's gypsum line.
• Recology: California-headquartered integrated waste and materials recovery company operating landfills, organics/compost, and MRFs. Comparable because Recology competes directly with Holloway Environmental and the Holloway–TPI MRF for Class III disposal and recovered-commodity volumes in California.
• Wilbur-Ellis (ag inputs division): Major U.S. distributor of crop inputs including fertilizers and soil amendments serving Western U.S. growers. Comparable because Wilbur-Ellis sells custom-blended soil amendments and agronomy services to the same San Joaquin Valley and Central Coast grower base Holloway Ag serves.

Regional players

• Casella Waste Systems: U.S. solid waste, recycling, and resource-management operator primarily in the Northeast. Comparable as an integrated landfill/MRF operator pursuing sustainable materials recovery, though its geography is largely non-overlapping with Holloway's California base.
