Smarter Polysilicon Decisions — Technology, Consulting & Owner's Engineering | NEXARSiL www.nexarsil.com

NEXARSiL is an independent polysilicon technology and services firm with over 25 years of hands-on production experience at the electronic grade level — including direct construction, commissioning, and operation of 11-9 purity (99.999999999%) polysilicon in the United States.
We offer three core service lines:
— Polysilicon Technology — Proven, 2026-current plant designs and technology packages for Siemens CVD process facilities. Designs validated in active commercial production, not theoretical models or vendor proposals.
— Operator Training — Structured training programs built from real commissioning and production floor experience. Covering process fundamentals, CVD reactor operation, chlorosilane handling, safety systems, and quality control.
— Independent Consulting — Owner's engineering, technology evaluation, CAPEX optimization, feasibility studies, vendor evaluation, and commissioning support — always on the owner's side, never the vendor's.
This presentation covers how NEXARSiL helps plant owners, project developers, EPC contractors, and technical decision-makers across the full polysilicon project lifecycle — from early feasibility through commissioning and stable production.
Additional topics covered:
— Why vendor-aligned advice costs owners millions in over-specified equipment and wasted CAPEX
— Independent evaluation of Siemens CVD and FBR process technologies
— CAPEX optimization delivering 5–15% savings on total installed project cost
— Four-phase methodology: Evaluate → Design → Build → Operate
— Global track record: United States, India, China, Qatar
NEXARSiL works exclusively on the owner's side of the table. No equipment to sell. No vendor commissions. No conflicts of interest. Every recommendation is driven purely by what performs in production.

1. NEXARSiL Independent Polysilicon Technology Partner Smarter Polysilicon Decisions Start Before the First Equipment Order 25+ Years Production Experience 11-9 Purity Grade Electronic Level 4 Project Phases Full Lifecycle Support nexarsil.com
2. The Problem With Polysilicon Projects Common Project Failures • Vendors sell equipment, not solutions • EPC contractors optimize their own billings • Technology licensors prioritize royalties over operability • Over-specified equipment wastes 10–20% of CAPEX • Operators receive minimal real training before startup • Project teams lack high-purity production experience NEXARSiL Difference • Purely owner-side — no equipment to sell • Independent of all vendors • Hands-on electronic and solar grade production • CAPEX savings of 5–15% through value engineering • Operator training built from commissioning reality • Deployed on multiple continents nexarsil.com

6. Our Four-Phase Methodology 1 E V A L U A T E Technology assessment, feasibility studies, and market analysis. Answer the right questions before committing capital. 2 D E S I G N Plant design, owner's engineering, and vendor selection. Translate technology into operationally sound, cost- effective designs. 3 B U I L D Construction management, CAPEX optimization, and vendor monitoring. Keep the project on schedule and within budget. 4 O P E R A T E Commissioning, operator training, and startup support. From mechanical completion to stable, profitable production. nexarsil.com
7. Built on Real Production Experience NEXARSiL's principal has directly constructed, commissioned, and operated electronic grade polysilicon to 11-9 purity (99.999999999%) under full production accountability. Separately developed and commissioned the first STC and DCS disproportionation to TCS system deployed in China — a first-of-kind program executed from design through stable commercial operations. Additional roles include owner's engineering on solar grade polysilicon facilities across India and Qatar, managing design, construction, and commissioning from the owner's side of the table. nexarsil.com
8. Why Independence Matters ⚠ EPC Contractors Profit from scope expansion and change orders. Feature creep benefits the contractor — not the owner. ⚠ Equipment Vendors Oversized equipment, premium specifications, proprietary components — all increase vendor revenue. ⚠ Technology Licensors Royalty structures, equipment exclusivity, and IP restrictions can constrain operations long-term. ✅ NEXARSiL Zero vendor relationships. Zero equipment sales. Every recommendation is driven purely by what works in production for the owner. nexarsil.com
9. Better Decisions. Lower Risk. Stronger Projects. Whether you are planning a new polysilicon facility, expanding capacity, or improving an existing operation — NEXARSiL provides the independent technical expertise your project needs.
