Case File · Siler City, NC · Chatham County
Wolfspeed chose 445 acres of the Chatham-Siler City Advanced Manufacturing (CAM) Site for the $5B John Palmour Manufacturing Center. A $76M state JDIG over 20 years, plus a ~$57.5M site-prep appropriation. First 200mm silicon-carbide crystal growth furnaces energized June 28, 2024. The fab is a template for how pre-sited Southeast megasites deliver.
Cited site read: 78/100 — entitlement path exceptionally clean; balance-sheet risk is the real diligence.

Chatham County, NC · 2022 — 2025
Three years from Cooper's announcement to first 200mm SiC furnaces online.
Pre-2022
North Carolina assembles the Chatham-Siler City Advanced Manufacturing Site
The Chatham-Siler City Advanced Manufacturing (CAM) Site is assembled under a coordinated state and county effort as a 'Select Site' certified megasite. Pre-grading, water and power capacity planning, and utility stubs are put in place before any tenant is selected — classic 'sell the site before you sell the deal' infrastructure play.
September 9, 2022
Governor Cooper announces Wolfspeed selects 445 acres
North Carolina Governor Roy Cooper's office announces that Wolfspeed has selected a 445-acre portion of the Chatham-Siler City Advanced Manufacturing Site for a $5B silicon-carbide wafer fabrication facility, subsequently named the John Palmour Manufacturing Center. State officials commit to a $76M Job Development Investment Grant (JDIG) over 20 years and highlight a $57.5M site-prep appropriation.
2022–2023
Local permitting and site mobilization
Chatham County and the Town of Siler City process the site-plan and utility work that follows megasite selection. With the CAM Site's pre-entitlement posture, the land-use review runs without a high-profile rezoning contest — the entitlement friction on record is materially lower than seen on comparable EV battery sites.
2023–2024
Construction accelerates; workforce pipeline activated
Vertical construction, cleanroom and crystal-growth infrastructure advance on site. Community college and four-year university partners (including NC State and Central Carolina Community College) stand up workforce pipelines for silicon-carbide technicians and process engineers. The state treats the workforce pipeline as a core deliverable alongside the fab itself.
June 28, 2024
First 200mm silicon-carbide crystal furnaces energized
Wolfspeed announces that the first 200mm silicon-carbide crystal growth furnaces at the John Palmour Manufacturing Center have been energized. This is a flagship milestone for both the company and the U.S. silicon-carbide supply chain — 200mm SiC is a next-generation process versus the industry-standard 150mm.
2024
Topping-out ceremony with Senator Tillis and state officials
Wolfspeed holds a topping-out ceremony at the site, with Senator Thom Tillis and North Carolina state officials in attendance. Company communications describe the facility as the 'world's largest, most advanced silicon-carbide facility.' (Superlative per Wolfspeed press release — verify before re-citing in client materials.)
February 5, 2025
Axios: facility 'nears completion'
Axios Raleigh reports that the John Palmour Manufacturing Center is nearing completion. Construction schedule has held broadly despite broader silicon-carbide industry demand-cycle pressure and Wolfspeed corporate-level capital restructuring activity.
Ongoing
Wolfspeed corporate restructuring tests the project's balance-sheet story
Wolfspeed navigates 2024–2025 capital restructuring activity reported in the semiconductor trade press. The John Palmour Manufacturing Center remains a flagship asset, but the capital-stack picture is the live risk on this case. North Carolina's incentive structure is performance-based, partially insulating state exposure.
The Counterparties
Every actor here is on the public NCEDP, Wolfspeed, or state legislative record.
Wolfspeed, Inc.
Applicant and Operator
Documented Record
Selected a 445-acre portion of the Chatham-Siler City Advanced Manufacturing Site in September 2022 and built the John Palmour Manufacturing Center. Energized the first 200mm SiC crystal growth furnaces on June 28, 2024.
Leading U.S. silicon-carbide producer. The operator-of-record for the case. Read Wolfspeed corporate-level SEC filings for the balance-sheet view — the land-use file is clean but the credit profile is what moves the capex calendar here.
Gov. Roy Cooper
Governor of North Carolina (2017–2025)
Documented Record
Announced Wolfspeed's selection on September 9, 2022, with a commitment to a $76M JDIG over 20 years. The announcement was coordinated with state legislative leaders and the Economic Investment Committee.
State-level political sponsorship was clean and visible. JDIG-denominated incentives in North Carolina are performance-based, a more durable structure than lump-sum grants when corporate restructuring is a risk.
North Carolina General Assembly
Appropriations Authority
Documented Record
Approved the approximately $57.5M site-prep appropriation supporting the Chatham-Siler City Advanced Manufacturing Site infrastructure that made the Wolfspeed selection possible.
State legislative appropriations were a critical, non-contingent piece of the stack. The NCGA's support for pre-siting megasites is a durable Southeast competitive advantage when competing against greenfield Texas or Arizona sites.
Chatham County Economic Development Corporation
County Economic Development
Chatham County, NC
Documented Record
Co-sponsored the CAM Site and ran local permitting and incentive coordination for the Wolfspeed selection. Partnered with the Town of Siler City on utility and infrastructure delivery.
County economic-development corporations are frequently the unglamorous but decisive layer for mega-manufacturing siting in the Southeast. Chatham's role here is the template for county-level megasite support.
Central Carolina Community College / NC State
Workforce Pipeline Partners
Documented Record
Announced in conjunction with the Wolfspeed selection, the workforce-pipeline plan pairs Central Carolina Community College technician programs with NC State advanced semiconductor curriculum support.
Workforce-pipeline commitments are increasingly a precondition, not an afterthought, for megasite wins. Document community-college partnerships before assuming 'labor available' on any Southeast greenfield.
Senator Thom Tillis
U.S. Senator (NC)
Documented Record
Attended Wolfspeed's topping-out ceremony at the John Palmour Manufacturing Center and publicly supported CHIPS Act and semiconductor-supply-chain policies aligned with the project.
Federal-level political support was visible through the construction cycle. Senate-level sponsorship is less load-bearing than governor or legislature backing on state incentives, but useful on federal CHIPS funding dynamics.
Why This Site Moved Fast
Each factor is the opposite of what stalls semiconductor megasites on greenfield land in other states.
Pre-Graded, Pre-Entitled Megasite
The CAM Site was already under Select-Site certification with grading, utilities, and land-use posture lined up. Wolfspeed walked into a known state.
Performance-Based JDIG Structure
The $76M JDIG is paid against actual performance over 20 years — durable to corporate-level distress and preserves state leverage if milestones slip.
Legislative Site-Prep Appropriation
The ~$57.5M NCGA site-prep appropriation was real money, not tax credits — the kind of non-contingent support that separates serious megasite jurisdictions from pretenders.
Community College + University Pipeline
Central Carolina Community College and NC State partnerships were announced with the project. The workforce pipeline was not an afterthought.
Utility Capacity Pre-Planned
CAM Site power and water capacity were sized before the tenant was known. For a 200mm SiC fab, utility build-out is the long-lead risk — here, it was already underway.
Corporate Balance-Sheet Risk Is the Live Risk
The land-use file is clean; the credit profile is not. Wolfspeed corporate restructuring in 2024–2025 is the live diligence lane. Separate entitlement risk from corporate risk.
The Intelligence
Before siting. Before construction. Before the first 200mm SiC furnace energized.
Site Analysis
John Palmour Manufacturing Center
CAM Site, Siler City / Chatham County, NC — ~445 acres
Favorable Conditions
Site Type
Pre-graded, pre-serviced megasite. No rezoning fight on the record.
State Incentives
JDIG ($76M/20y) plus GA-appropriated site-prep funds. Announced by Gov. Cooper's office Sept 9, 2022.
Risk — Corporate Balance Sheet
Wolfspeed's 2024–2025 restructuring activity kept the fab in view but added capital risk.
Risk — SiC Demand Cycle
EV demand softness has compressed silicon-carbide capex timing industry-wide.
Recommendation
PRE-SITED MEGASITE PLAYBOOK. The Chatham-Siler City Advanced Manufacturing site gave Wolfspeed a pre-entitled, pre-serviced 445-acre pad. Combined with JDIG and state site-prep funds, the approval-to-energization cadence was exceptionally fast for a first-of-kind 200mm silicon-carbide fab. Pair corporate balance-sheet diligence with the land-use file — the site is clean; the credit is not.
