Strong Longevity of Meyer Burger Products

• A major challenge for the performance of solar modules is the so-called PID effect ("potential induced degradation") which can lead to massive product failure in the field

• Swiss EPFL has recently presented a comparative study between Meyer Burger HJT+SWCT® (SHJ+SWT), competitor HJT (SHJ), TOPCon and PERC glass-glass products

• According to the EPFL study tested bifacial TOPCon and PERC technologies are more sensitive to PID than HJT, Meyer Burger's SWCT® further mitigates PID

Financing Plan To Close The Funding Gap

Financing mix:

• Funding gap of CHF 450m to complete construction of Colorado and Arizona manufacturing facilities
• Rights issue with target proceeds of around CHF 200m
• Remainder to be debt financed from additional financing options: export financing loan, loan from the U.S. Department of Energy, and/or advanced manufacturing tax credit (so-called 45X)
• Export agency credit financing loan from a commercial bank, supported by an export agency credit guarantee from the German government, in the amount of up to USD 95 million subject to certain conditions, including finalising the long-form documentation
• USD 200-250 million U.S Department of Energy ("DOE") guaranteed 10-year loan from the Federal Financing Bank(1)
• Advanced manufacturing tax credit (so-called 45X) of up to USD 300 million to monetise future tax credits with term of 6 years subject to due diligence and the entering into requisite binding agreements
• In parallel, continue to explore potential strategic partnerships to drive longer-term growth and reduce capital intensity

Source: Company Information; 1) After successfully completing Part I of the DOE process, the Group was formally invited in February 2024 to submit Part II of an application for such loan. DOE's invitation to submit a Part II application is not an assurance that DOE will invite the applicant into the due diligence and term sheet negotiation process, that DOE will offer a term sheet to the applicant, or that the terms and conditions of a term sheet will be consistent with terms proposed by the applicant. The foregoing matters are wholly dependent on the results of DOE review and evaluation of a Part II application, and DOE's determination whether to proceed.
