SÜSS MicroTec's portfolio is clearly bifurcated: high-margin Stars (AI-focused bonding, UV full-field scanners and advanced backend for SiC) are powering growth and warrant heavy capacity and R&D investment, while resilient Cash Cows (photomask cleaning and mask aligners) generate the cash to fund that push; speculative Question Marks (hybrid bonding, GreenTrack cleaning, inkjet additive) need targeted capital to prove scale, and legacy Dogs are being wound down-together this allocation strategy is critical to hit the company's 2030 revenue and EBIT margin targets, so read on to see which bets matter most.

SÜSS MicroTec SE (0Q3C.L) - BCG Matrix Analysis: Stars

Stars

Temporary Bonding and Debonding Solutions (TBD) dominate the high-growth AI memory market with a 65% global market share as of late 2025. Quarterly shipments increased from 0.8k units in Q1 2024 to 2.4k units in Q4 2024 (tripling year-on-year), with volume continuing to expand through 2025. Gross profit margin for the segment stands at approximately 42.3% in FY2025. Addressable market long-term CAGR is projected at 7% through 2030. Capital expenditure by HBM producers (notably Samsung and Micron) rose by an estimated 18% year-on-year for 2025 and is expected to increase another 12% in 2026, directly supporting TBD demand. Production capacity was expanded at the Zhubei site in Taiwan in mid-2025, adding an incremental 30% throughput to meet AI-backend demand. A temporary pause in order intake during late 2024 (approx. 6-8 weeks) was observed while customers focused on installation, but backlog replenishment resumed in early 2025.

UV Projection Scanning Systems hold an effectively exclusive position as the sole supplier of full-field scanners to major foundries including TSMC for CoWoS packaging. The unit commands ~99% market share in the full-field UV scanning niche for advanced packaging. Systems revenue contributed ~22% to group revenue in FY2025 and supports management's target group revenue CAGR of 9-13% through 2030. Installed base utilization for UV scanners remained above 88% in 2025 despite platform refresh timing; 2026 is anticipated as a transitional year for new platform introductions. Average selling price (ASP) per full-field UV scanner is in the range of EUR 3.8-4.5 million depending on configuration; service and consumables drive recurring high-margin aftermarket revenue (~38% gross margin on consumables/services).

Advanced Backend Solutions for Power Semiconductors (SiC/GaN-focused) are delivering double-digit growth, reflecting a target market CAGR of 10.9% through 2030 for power and compound semiconductors. New customer wins in the SiC segment contributed ~€12.4m incremental revenue in FY2025 and are projected to contribute €35-40m annualized by FY2028 under current ramp plans. Segment-specific gross margins are in the mid-30s percent now, with pathway to group EBIT margin targets of 20-22% by decade-end driven by scale and higher-value service mix. Coating and bonding technologies for SiC deliver measurable energy-efficiency gains at the device level and command premium pricing in advanced power-backend toolsets.

Key growth drivers for the Stars segments:

• Surging AI memory demand and HBM capex expansion (2025-26), supporting TBD volumes and pricing.
• Exclusive full-field UV scanner position in CoWoS/advanced packaging enabling price power and high aftermarket attach rates.
• Structural shift to electrification and renewables driving SiC/GaN adoption and backend equipment demand.
• Strategic capacity expansion (Zhubei) and targeted customer wins accelerating revenue capture.

Operational and market dynamics to monitor:

• Short-term order intake variability due to customer installation cycles (observed late 2024).
• Platform refresh timing in 2026 for UV scanners-risk of transient investment pauses offset by aftermarket strength.
• Competition and potential new entrants in SiC/GaN backend-necessity to protect IP and service ecosystem.
• Macro semiconductor cyclical risks; long-term CAGR assumptions (7% TBD market; 10.9% power market) underpin Star classification.

SÜSS MicroTec SE (0Q3C.L) - BCG Matrix Analysis: Cash Cows

Cash Cows

Photomask Solutions represent a mature and highly profitable business unit with a dominant position in the global mask cleaning market. This segment achieved an excellent gross profit margin of 40.2% in H1 2025, significantly exceeding the company's historical averages (annual gross margin 2019-2024: 30.5%-36.8%). Photomask revenues for the trailing twelve months (TTM) to H1 2025 are estimated at €145.6 million, representing roughly 34% of group sales. Market growth for photomask equipment is steady but moderate, with an estimated CAGR of 6.89% (2024-2030). SÜSS MicroTec holds a leading share in high-end photomask cleaning (estimated market share: 28%-33% in the premium segment), delivering consistent cash flow that underpins the group's R&D program. Management guidance and consensus projections target R&D spend rising to 11% of sales by 2030 (from ~8.4% in 2024), financed in large part by cash generated from Photomask Solutions. Even with periodic demand fluctuations from China (regional revenue exposure H1 2025: ~22% of photomask sales), the segment remains a stable pillar of the company's financial structure.

Mask Aligner Systems continue to be a foundational technology, maintaining a strong presence in the global mask aligner market (estimated market size: $2.5 billion). SÜSS MicroTec is one of the top three global players alongside ASML and EV Group, with an estimated market share in aligners of 20%-25% depending on segment / geography. The installed base is large and durable, generating recurring service and consumables revenue that currently accounts for approximately 18% of total group sales (H1 2025). Annual service revenue attributable to aligners is estimated at €76-82 million (TTM basis). Technology maturity allows disciplined CAPEX levels (~3.0%-3.3% of sales), enabling high returns on deployed capital; returns on capital employed (ROCE) for aligners averaged 15%-18% over 2022-2024. These systems provide steady financial liquidity needed to underwrite expansion into more speculative technology adjacencies (pilot projects, new product incubation).

• Role as Cash Cows: Both Photomask Solutions and Mask Aligners generate predictable free cash flow, enabling sustained R&D (target 11% of sales by 2030) and selective M&A or venture investments.
• Financial Metrics Supporting Cash Cow Status:
  • Combined contribution to group EBITDA: estimated 52%-58% (H1 2025 TTM).
  • Free cash flow yield from these segments: ~6%-8% of segment revenue annually.
• Risks to Cash Flow Stability:
  • Geographic demand variability (notably China exposure ~20%-25% across both units).
  • Cyclical semiconductor investment cycles can compress near-term order intake by 10%-25% in down-cycles.
• Strategic Use of Cash:
  • Fund high-margin R&D and maintain capital-light operations for mature lines.
  • Support commercialization of adjacent technologies without diluting core cash generation.

SÜSS MicroTec SE (0Q3C.L) - BCG Matrix Analysis: Question Marks

Question Marks (Dogs category focus): These business units currently sit in high-growth markets but have low relative market share within SÜSS MicroTec's portfolio. They require significant investment to either scale to Star status or be divested. The following sections describe three core Question Marks: Hybrid Bonding Platforms, GreenTrack Wafer Cleaning Systems, and Inkjet Technology for Additive Manufacturing.

Hybrid Bonding Platforms - status and outlook:

Hybrid Bonding Platforms represent a strategic, high-potential entry into 3D IC and advanced interconnect technology (wafer-to-wafer and die-to-wafer). SÜSS MicroTec has secured initial orders (reported pilot orders: ~10 systems as of 2024) but remains in an early-stage commercial ramp. The segment carries substantial R&D and capital expenditure requirements: planned incremental R&D investment of approximately €25-€40 million in 2025-2027 as part of the 2026-2027 portfolio refresh. Market assumptions include CAGR for 3D IC interconnects of 20-30% through 2030. Competitive pressures are strong from established frontend/back-end equipment suppliers; SÜSS's relative market share is estimated below 5% in target subsegments today. Successful commercialization is viewed as critical to reach the company's Strategy 2030 revenue target of €750-€900 million (hybrid bonding could contribute €100-€250 million by 2030 under a successful scale scenario).

Key risks and success factors for Hybrid Bonding:

• Risk: High development cost and long validation cycles with tier-1 fabs and OSATs;
• Risk: Competitive displacement by incumbents with scale manufacturing;
• Success factor: Achieve yield and throughput parity for volume production by 2026-2027;
• Success factor: Secure multi-year purchase agreements with at least two major customers by 2027.

GreenTrack Wafer Cleaning Systems - status and outlook:

GreenTrack is positioned to capture demand for environmentally friendly wafer cleaning solutions (200mm for MEMS/Power in 2026, 300mm for logic/memory later). Current revenue contribution is minimal (<€5 million in 2024). Roadmap: 200mm product launch targeted 2026, 300mm expected 2027-2028. Initial development and pilot costs are estimated at €10-€20 million through 2026, with additional commercialization spend of €15-€30 million in 2027-2028. Market drivers include stricter cleanliness standards and a shift away from legacy chemistries; however, the cleaning equipment market is fragmented and competitive, placing GreenTrack in the Question Mark quadrant until customer validation and scale are proven.

Key risks and success factors for GreenTrack:

• Risk: High initial certification and customer acceptance hurdles;
• Risk: Price competition and incumbents' retrofit solutions;
• Success factor: Demonstrable reductions in hazardous chemicals and OPEX for customers;
• Success factor: Rapid deployment in MEMS/power niches, then scaling to 300mm logic/memory.

Inkjet Technology for Additive Manufacturing - status and outlook:

Inkjet additive manufacturing is an exploratory initiative targeting panel-based packaging and potential replacements for spin coating (e.g., applications such as TSMC's CoPoS). Technology validation with key partners is ongoing; volume production is not expected until ~2028. Current internal investment through 2024-2025 is modest (R&D ~€5-€10 million), with projected capital commitments rising to €20-€50 million by 2026-2028 contingent on successful validation. Market opportunities are significant in advanced packaging, but the addressable market share for SÜSS is unproven at scale. The unit is a strategic Question Mark within Strategy 2030 aimed at diversifying technological footprint and opening new adjacent markets.

Key risks and success factors for Inkjet Technology:

• Risk: Long qualification cycles with foundries and OSATs;
• Risk: Capital intensity and uncertainty of adoption vs. incumbent processes;
• Success factor: Successful pilot conversions with at least one major OSAT or foundry by 2027;
• Success factor: Demonstrated cost/performance advantage in panel-based packaging by 2028.

SÜSS MicroTec SE (0Q3C.L) - BCG Matrix Analysis: Dogs

Dogs - Legacy Coating and Developing Systems: legacy coating and developing systems for low-end applications face intensifying price competition from low-cost Asian OEMs and a maturing market demand profile. These products exhibit materially lower gross margins (typically 10-15% range) versus the company's advanced packaging and lithography offerings (EBIT margins above 20% target). Under the 2030 "streamlined portfolio" strategy, capex and R&D allocations are being reweighted away from these lines; reported internal budget shifts indicate a reduction in allocated R&D spend for legacy coating/developing of approximately 40-60% versus peak years. Revenue contribution from these lines has contracted to an estimated single-digit share of total group revenue (approx. 5-9% in the latest reporting periods) and requires disproportionate administrative and field-support effort relative to generated cash flow.

Dogs - Discontinued MicroOptics Operations: MicroOptics was classified and reported as a discontinued operation late 2023 and no longer contributes to the group's forward growth trajectory. The disposition removed a non-core business that historically exhibited weak synergies with semiconductor equipment and delivered low incremental margin and cash conversion. Management commentary and subsequent financials show the divestment aided headline margin improvement; reported EBIT margin improved from 14.1% in 2024 toward the higher mid-teens/low-20s target band driven by cost elimination and redeployment of capital to higher-margin units.

Implications for portfolio and capital allocation:

• Reduced investment: Continued de-prioritization of legacy lines with diminished capex and R&D allocations to favor advanced packaging, lithography, and AI-related tooling.
• Operational streamlining: Phasing out lower-margin product lines to improve overall EBIT and free cash flow conversion.
• Resource redeployment: Redirecting working capital and manufacturing capacity to product lines with targeted EBIT margins >20%.
• Aftercare and service burden: Legacy lines still require service networks and spare parts inventories, creating an ongoing overhead drag until complete phase-out or third-party transfer.

Financial and operational risk considerations:

• Short-term revenue volatility as legacy product sales decline - projected year-on-year revenue decline from Dogs segment of 20-40% until run-rate stabilization or divestment.
• One-off charges and restructuring costs associated with phase-outs or asset disposals - modeled impairment and exit costs in prior periods materially affected reported EPS and cash flow.
• Potential residual liabilities from discontinued MicroOptics (warranty/service) requiring limited provisions - management notes indicate remaining obligations are immaterial but present.
• Opportunity cost: capital and talent committed to maintaining Dogs could otherwise accelerate growth in Stars and Cash Cows (advanced packaging, high-precision tooling).
