Notes and ESG footnotes

Investments =	'Purchase of property, plant and equipment' + 'Purchase of intangible assets and other assets' incl. capitalization of R&D expenses
Capital Employed =	'Total assets' – 'Cash and cash equivalents' – 'Financial investments' – 'Assets classified as held for sale – ('Total Current liabilities' – 'Short-term debt and current maturities of long-term debt' – 'Liabilities classified as held for sale')
RoCE =	Operating profit from continuing operations after tax / Capital Employed = ('Operating profit' – 'Financial result excluding interest result' – 'Share of profit (loss) of associates and joint ventures accounted for using the equity method'-'Income tax') / Capital Employed
Working Capital =	('Total current assets' – 'Cash and cash equivalents' – 'Financial investment' – 'Assets classified as held for sale') – ('Total current liabilities' – 'Short term debt and current maturities of long-term debt' – 'Liabilities classified as held for sale')
DIO (days inventory outstanding; quarter-to-date) =	('Net Inventories' / 'Cost of goods sold') x 90
DPO (days payables outstanding; quarter-to-date) =	('Trade payables' / ['Cost of goods sold' + 'Purchase of property, plant and equipment']) x 90
DSO (days sales outstanding; quarter-to-date) =	('Trade receivables' - 'reimbursement obligations')* / 'revenue' x 90
	*without debtors with credit balances

Book-to-bill = Orders received / Revenue in Euro per quarter

Orders received contains order backlog and external customer forecast. External customer forecast includes consignment stock forecast by customers. Not included are internal consignment replenishment orders.

Orders received does not include unconfirmed orders received. Unconfirmed demand will be reported as orders received and in book-to-bill when it gets confirmed.

Orders received may not coincide with the IFRS 15 definition of a contract with a customer.

Like-for-like calculation as of Q3 FY21: In the light of continued strong order intake, Infineon has temporarily switched from automatic to manual order confirmation. As a result, comparatively fewer orders are being confirmed. To provide a comparable view, the book-to-bill figure has been adjusted by assuming the same confirmation rate of newly received orders as in the previous quarter.

ESG footnotes:

• 1) This figure takes into account manufacturing, transportation, own vehicles, travel, raw materials and consumables, chemicals, water/waste water, direct emissions, energy consumption, waste, etc. as well as direct and indirect energy-related emissions by manufacturing service providers. It is based on data collected internally and publicly available conversion factors and relates to the 2021 fiscal year.
• 2) This figure is based on internally established criteria, which are described in the explanatory notes. The figure relates to the 2020 calendar year and takes into account the following application areas: automotive, LED, induction cookers, servers, renewable energy (wind, photovoltaic) and cell phone chargers as well as drives. CO2 savings are calculated based on the potential savings generated by technologies in which semiconductors are used. The CO2 savings are allocated based on Infineon's market share, semiconductor share, and the lifetime of the technologies concerned, based on internal and external experts' estimations. Despite the fact that carbon footprint calculations are subject to imprecision due to the complex issues involved, the results are nevertheless clear.
