AI related opportunity is larger than we initially expected

So far, we received AI related orders for our temporary bonders, debonders and cleaners worth ~ € 100 million.

• Demand for our solutions is boosted in particular by dramatic capacity increase at Korean and Taiwanese HBM (high bandwidth memory chip) manufacturers. +
• After a first order in June 2023, we received the largest POs in September and October. +
• As a result, we achieved the bonder's highest ever order intake in the third quarter of 2023. +
• To meet demand, we are qualifying our production site in Hsinchu (Taiwan) to build the XBS300 temporary bonding platform in the future. For this, we are hiring > 50 new employees. +

Status of deliveries destined for China

What has changed for deliveries to China?

By end of July, we informed customs about deliveries to China and received approvals within a few days. As of the beginning of August, customs has been forwarding numerous cases to the Federal Office for Economic Affairs and Export Control ("BAFA") which typically leads to delays of several weeks or even months. In general, the legal basis for deliveries of our equipment to China has not fundamentally changed.

27

cases

with a total value of € 19.9 million (as of 9th Nov 2023) have been forwarded to BAFA

Approved cases with a total value of € 2.0 million (as of 9th Nov 2023)

• Good order intake and very high order backlog remain a solid foundation for growth in Q4 2023 and beyond (despite the adjustment of the 2023 sales target)
• Absolute gross profit and EBIT increased yoy
• Gross profit margin and EBIT margin not in line with expectations, mainly because of China related shipment delays, an unfavorable product mix and increased outsourcing activities
• Company has nevertheless created value for shareholders in 9M 2023 (earnings per share +88.9%)
• Net cash position decreased due to further built up of inventories

• Decrease in order intake yoy after very strong 9M in fiscal year 2022, but very good order situation on Bonder product lines
• Sales increased by 11.5 % yoy, mainly driven by bonder business
• Gross profit margin decreased because of lower sales with high margin tools

• EBIT margin went up from 5.9% to 6.9%, due to strong Q2 results

• Order intake decreased, but remains on a good level compared to prior years

• High order backlog (~ €170 million as of September 30) provides huge growth opportunity
• Sales benefited from high backlog and improved supply chain situation
• Absolute gross profit and EBIT improved
• Decline in gross profit margin and EBIT margin due to higher R&D costs for the development of a disruptive wafer cleaning solution

1) Total sales include internal sales (sales to other divisions) since 2021; gross profit margin and EBIT margin are calculated on the basis of total sales.

Further inventory build-up due to supply chain bottlenecks extend the balance sheet

Assets as of September 30, 2023* in € million

€ 19.9 million decrease in non-current assets due to a reduction of property, plant and equipment, following the reclassification of MicroOptics to discontinued operation

Increase mainly attributable to a € 19.6 million rise in inventories and new position of assets held for sale due to the planned divestment of SUSS MicroOptics

Cash position decreased within the last nine months due to further inventory built-up

Liabilities and equity shaped by increase in contractual liabilities and equity

Liabilities and equity as of September 30* in € million

Stable equity ratio

• Contractual liabilities increased further by down payments by customers of € 16.3 million in the last nine months and new balance sheet position of liabilities from "assets available for sale"
• 3

Decrease in pension obligations of € 3.5 million and financial liabilities from leasing obligations of € 4.3 million

Revised guidance due to delayed deliveries to China and unsatisfying margins

Our adjusted guidance 2023

1) Without SUSS MicroOptics 2) Including one-off effects of € 3.1 million. Operating EBIT margin thus accounted to 9.9%.

Our scenarios for the fourth quarter and full year 2023

• Sales trend in Q4 2023 will be determined by the uncertainty as to what extent we will be able to process deliveries to Chinese customers; for this reason, we have extended our sales forecast to a range of € 40 million in total
• Gross profit margin benefits twice from increased deliveries to China, because (1) mainly high-margin tools are held back and (2) a positive volume effect is generated due to non-project related fixed costs in the COGS
• EBIT benefits disproportionately from higher volume as OPEX in Q4 2023 is independent from sales level

* without MicroOptics segment
