Investor Presentation Key CEO messages

• Best year in company history in terms of order intake and sales
• AI-driven order intake for temporary bonding equipment in H2 2023 amounting to ~ € 130 million
• Strong Q4 2023 with sales of more than € 100 million and EBIT margin close to 15%
• Gross profit margin and EBIT margin declined due to an unfavorable product mix, capacity ramp-up in Taiwan and an increased level of engagement with external manufacturing partners

We are in a growth-driven transformation process

Sale of the MicroOptics business clearly increased the focus of our company SUSS MicroTec has become a pure play semiconductor equipment company

Division Highlights 2023

Strong demand across both divisions

Advanced Backend Solutions:

• Outstanding order intake for temporary bonding equipment, mainly supporting AI-driven HBM capacity ramp-up
• Almost stable business with mask aligners
• Order entry and sales for coaters have been rather weak in 2023 in line with the overall semiconductor market
• Strategic update:
  • ‒ clear focus on high-volume manufacturing allows to streamline the portfolio (see page 7)
  • ‒ JDA with Heraeus creates additional potential for our Inkjet business (see page 8)

Photomask Solutions:

• Ongoing good order intake, mainly from Asian customers
• Significant yoy sales increase of 83.8% achieved, based on an ongoing well-filled order book
• Development of a disruptive wafer cleaning solution continued; first automated prototype installed in Sternenfels Application Center

Focus on high-volume manufacturing markets while semi-automated tools will be phased-out during next years in Advanced Backend Solutions business unit

Bonding Systems

Semi-automated automated

Coating Systems

Imaging Systems

SUSS MicroTec and Heraeus jointly work on EMI* shielding

Idea: EMI shielding by combining metallic specialty inks and digital printing processes from Heraeus and the JETx high-volume inkjet platform from SUSS MicroTec

Target Devices: Mobile phones, wearables and IoT devices

ESG enhancing solution

Inkjet printing is a very sustainable solution, compared to the traditional subtractive manufacturing techniques. Only printing the required amount of material, exactly where it is needed, significantly reduces the amount of wasted material and eliminates removal-processing steps of excess material.

• Record order intake and very high order book remain a solid foundation for growth in 2024 and beyond
• Absolute gross profit increased, but gross profit margin declined, mainly caused by an unfavorable product mix, transformation costs due to development of external production partners and ramp-up costs of bonding manufacturing in Taiwan
• Absolute EBIT and EBIT margin declined yoy caused by higher R&D and administration expenses
• Net cash position at year end decreased as a result of further built up of inventories; in January 2024, net cash position went up by € 75 million due to the closing of the sale of our MicroOptics business

• Further increase in order intake yoy driven by multiple orders in the bonding segment, especially for temporary bonding equipment for AI-applications
• Sales increased yoy, driven by bonder business, which more than compensated for the rather weak lithography sales in 2023
• Gross profit margin decreased because of a disproportionately increase in cost of sales and an unfavorable product mix
• EBIT margin decreased from 13.5% to 9.3% (EBIT 2022 includes a positive one-off effect of € 0.8 million)
• Order intake decreased slightly, but remains on a very good level compared to prior years
• High order book (~ €166 million as of December 31, 2023) provides further growth opportunity
• Sales benefited from high order book and improved supply chain situation
• Absolute gross profit and EBIT improved strongly
• Decline in gross profit margin due to additional costs incurred for the ongoing onboarding of new external production partners

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

Reclassification of MicroOptics business characterizes the balance sheet

Assets as of 31 Dec.

€ 18.8 million decrease in non-current assets, in particular as a result of the reclassification of the MicroOptics business into current assets ("assets held for sale")

• Increase of € 48.7 million mainly attributable to the reclassification of the MicroOptics noncurrent assets to "assets held for sale" and to the increase in inventories by ~ € 24 million to service the order book of our continuing operations with materials 2
  • Cash and cash equivalents decreased by € 13.3 million

Solid equity ratio of 47.8% at year-end

Liabilities and equity as of 31 Dec. in € million

Stable equity position

Current liabilities up by € 24.1 million yoy, especially because of reclassification of MicroOptics division to "liabilities associated with assets held for sale" (€ 8.9 m), increased contract liabilities (€ 9.1 m) and higher tax liabilities (€ 4.8 m)

Decrease in non-current liabilities mainly driven by reclassification of MicroOptics segment to "liabilities associated with assets held for sale"

Cash position has decreased by € 13.3 million over the course of the year

*This figure does not include cash and cash equivalents of € 0.6 million from the MicroOptics business

Cash inflow of € 75 million significantly strengthens our financial position
