2. Overview
• CleanWafer has developed a patented,
disruptive technology which enables the
manufacture of high-purity silicon at a fraction
of current costs with no carbon emissions. In
addition, all of the byproducts of the
manufacturing process can be resold.

3. Problem & Opportunity
• Silicon Wafers Too Expensive
–CleanWafer can provide an 80% Silicon
Wafer Cost Reduction
• Silicon Manufacturing Too Dirty
–CleanWafer has no CO2emissions

4. Who Buys Silicon?
• Semiconductor Manufacturers ($9B/year)

11. Investment and Milestones
• Series A = $15 million
• Pilot Plant = 75 metric tons/yr pure silicon (40 tons
of silicon ingot/yr which produces 20 million square
inches of wafer/yr)
• 6-12 month lead time
• Capital Cost = $12.5 million
• Contingency = $2.5 million

12. Business Model
• Direct sales of wafers into the
microelectronics industry
• EBITDA of $20 million/yr from wafer sales
• EBITDA $0.5 million/yr from byproducts
• Additional revenue from byproduct sales
• In year 2, pursue licensing deals worldwide

13. Value to an Acquirer
To reach = EBITDA of $150 million annually,
CleanWafer is 92% less capital cost
For a 10,000 Ton Plant:
• $250M: One-time Cost to Build
• $1.25B: Annual Cash Flow
• >$1B: Annual Change to the Bottom Line
• Becomes Lower Risk When Demonstrated
• Green technology with no carbon emissions

14. Exit Strategy for Investors
• CleanWafer Projects a Liquidity Event in Next 3-5 Years
• Potential Global Licensing Model
• Building additional plants
• Enable Acquirer to Achieve $5B/Year Industry Savings
– Product Sales
– Process Licensing Royalties
– P/E Ratio of 8: $40B Market Capitalization

15. Conclusion
• CleanWafer’s Value is a Patent-Pending
Process
– Multibillion Industry Savings
– Fast Exit
– High Returns
– Significant Green Value
