Career path: - Carl Zeiss AG: ~10 years in various technical and commercial roles - JENOPTIK AG: CTO/COO, then CEO July 2007 — mid-2017 (10-year tenure) - Dr.-Ing. Michael Mertin Management Consulting (2017–2025): independent consultant focused on PE and M&A; numerous acquisition and divestment projects; advisory work at the intersection of technology manufacturing and private equity - AT&S: President & CEO, May 2025–April 2028 (3-year initial term)
JENOPTIK track record (2007–2017): Mertin took over JENOPTIK when it was a mid-size German precision optics and photonics manufacturer with underperforming segments. Under his decade of leadership, revenue increased by more than 35% from ~€500M to ~€670M by 2015 and earnings moved from near-break-even to ~€50M net income. He executed a strategic refocusing from a conglomerate structure to a cleaner three-division model (Optics & Life Science, Motion, Sensors & Actuators). The business model — asset-heavy precision manufacturing with long customer qualification cycles and large-capex production lines — is structurally very similar to AT&S. JENOPTIK under Mertin was not a dramatic turnaround or hypergrowth story, but it was a competent execution of a capital-cycle strategy. Revenue and margins improved steadily.
Caution flag on JENOPTIK exit: Mertin departed JENOPTIK in 2017. The search record does not show a public acrimonious departure — he transitioned to advisory/consulting and apparently left on reasonable terms. No legal or regulatory issues attached to his departure.
M&A/PE advisory phase (2017–2025): 8 years in deal advisory is a double-edged signal. On the positive side, Mertin will have seen dozens of industrial companies’ books and understands what management teams get right and wrong. On the negative side, he hasn’t operated a manufacturing business in real time for 8 years — a gap at a moment when AT&S is running the most critical plant ramp in its history.
Prior regulatory actions/litigation: No disclosed SEC enforcement (AT&S is not a U.S. filer), no Austrian FMA (Finanzmarktaufsicht) actions, no publicly reported personal litigation.
Overall CEO assessment: Relevant background (precision manufacturing, capex cycles, photonics = adjacent to semiconductor technology); demonstrated competence at JENOPTIK; the 8-year advisory gap is the primary concern. Hired by the new post-Androsch board specifically to execute on someone else’s capital investment blueprint. This is the job he needs to do — not originate strategy, but execute and deliver. That framing reduces the relevance of the advisory gap somewhat.
Education: MBA, WHU Otto Beisheim School of Management (Germany’s top private business school)
Career path: - Fresenius Group and Fresenius Kabi AG: ~20 years across Europe and Asia; roles including Global CFO of Fresenius Kabi and CEO of Fresenius Kabi Asia. Fresenius is a large, complex, multi-country healthcare company — excellent training ground for IFRS reporting, debt management, multi-currency P&L, and Asia operations. - Heraeus Group: Various executive roles including Asia region CEO - DAMAC Group (Dubai): Group CFO, revenue >$5B, until Dec 2025. DAMAC is a private real estate and technology conglomerate — significant balance sheet complexity, multi-billion UAE dirham/USD portfolio, high-leverage real estate. CFO role here required managing complex capital structures and investor relations in a non-public company environment. - AT&S: CFO, February 2026–2029
Track record: Steen has 25+ years across large multinationals with significant Asia exposure (critical for AT&S given Kulim, Shanghai, Chongqing). His DAMAC role required managing real estate development leverage — not exactly semiconductor substrate, but balance sheet stress testing in a capital-intensive business is directly relevant to AT&S’s deleveraging phase. No prior regulatory actions or litigation identified.
Flag: DAMAC is a private company with opacity. His CFO role there is harder to validate externally than a public company tenure. Not a red flag per se, but not fully verifiable.
Overall CFO assessment: Internationally experienced, relevant balance sheet expertise, Asia background valuable. Very new (Feb 2026 — only 2 months into the role at time of writing). Cannot yet assess performance at AT&S.
Education: Applied Physics doctorate, Technical University of Graz
Career path: - Joined AT&S in 2001 — has spent virtually his entire career at the company (22+ years) - Based in Shanghai since 2002; led R&D and operations in Asia for over a decade - Directly responsible for design, construction, and commissioning of both the Shanghai and Chongqing plants - Led the commercialization of mSAP (modified Semi-Additive Process) for AT&S — the core technology that enables high-density PCBs and substrates - COO of Mobile Devices & Substrates business unit from 2012 before becoming CTO
Assessment: Griehsnig is the single most important executive on the team. He is the one person who knows exactly how AT&S’s manufacturing processes work, where the yield problems are, and how to fix them. He built the Shanghai and Chongqing plants from the ground up — Kulim is a scaled evolution of the same approach. His continued presence as CTO is the most important governance fact about AT&S management. Mertin and Steen are new; Griehsnig is the institutional memory.
Education: Business degree, Ludwig-Maximilians-University Munich
Career path: - Siemens AG: ~20 years in various technical and commercial roles - Hewlett-Packard: Senior positions in California (7 years) - Diebold Nixdorf: President and CEO, 2013–December 2017 — led the merger of Diebold and Wincor Nixdorf to create the world’s largest ATM provider. Achieved synergy targets, executed one of the largest US-German cross-border mergers. However: stepped down December 2017 following a downward earnings guidance revision citing banking business challenges and product complexity problems. Stock had materially underperformed. - Coherent Inc.: CEO 2020–2022 — led one of the leading photonics manufacturers; tenure was short but Coherent was operationally performing well during this period. - McKinsey & Company: Senior Advisor (current alongside AT&S board role) - Cohu Inc.: Board member
Diebold Nixdorf flag: The departure after an earnings guidance cut and execution challenges is worth noting — it parallels the exact situation AT&S is now in (ambitious manufacturing transformation, complex integration, execution challenges). The Diebold Nixdorf outcome was not catastrophic — the merger itself was executed — but Mattes left when the execution got hard. As AT&S’s supervisory board chair, the same dynamic could recur if the Kulim ramp disappoints. He is not the executive — but his credibility with shareholders depends on the management team he oversees delivering.
Independence: Declared independent under C-Rules 53 & 54 of the Austrian Corporate Governance Code. No disclosed financial relationship with AT&S prior to appointment. McKinsey advisory role is unrelated to AT&S.
| Holder | Type | Stake | Est. Value (€) | How Held |
|---|---|---|---|---|
| Dörflinger Privatstiftung | Founding family foundation | ~18% | ~€612M | Long-term, not traded |
| Androsch Privatstiftung + AIC | Late H. Androsch’s foundation | ~17.55% | ~€597M | Long-term, not traded |

| Free float | Various | ~61–64% |
Share count: 38,850,000 shares — UNCHANGED since at least 2013. AT&S financed its entire €1B+ Kulim expansion through debt + asset sales + institutional grants without issuing a single new share. This is an exceptional outcome for shareholders and reflects the founding bloc’s anti-dilution instincts.

Recent activity from the managers’ transactions disclosure page:
| Date | Name | Role | Transaction | Amount/Price |
|---|---|---|---|---|
| Apr 14, 2026 | Gertrude Tumpel-Gugerell | Supervisory Board member | BUY | Amount undisclosed |
| Feb 19, 2026 | Günter Pint | Unknown (possibly departing executive) | SELL | Amount undisclosed |
| Dec 12, 2025 | Gertrude Tumpel-Gugerell | Supervisory Board member | BUY | Amount undisclosed |
| Jun 7, 2022 | Dörflinger-Privatstiftung | Associated with Georg Riedl | BUY | 10,000 shares @ €53.00 = €530K |
| Jun 2, 2022 | Dörflinger-Privatstiftung | BUY | 10,000 shares @ €55.00 = €550K | |
| Feb 8, 2022 | Dörflinger-Privatstiftung | BUY | 326,342 shares @ €41.10 = €13.4M | |
| Mar 31, 2022 | Peter Schneider | Former CSO / Interim CEO | BUY | 422 shares @ €50.30 = €21K |
| Jun 18, 2021 | Simone Faath | Former CFO | BUY | 1,000 shares @ €35.60 = €35.6K |
Key observations: 1. The Dörflinger foundation bought €13.4M of stock in February 2022 and another €1.08M in June 2022 at €41–55 range — these are now worth 2–4x given current ~€87 price. They have NOT sold despite the +420% re-rating from the May 2025 trough. This is the strongest insider signal available. 2. Gertrude Tumpel-Gugerell (independent supervisory board member) bought twice in Dec 2025 and Apr 2026 — in the €20–87 range during the re-rating. Open-market buying by an independent board member is a genuine alignment signal. 3. New management (Mertin, Steen, Griehsnig) have no disclosed open-market purchases. This is a gap. They are compensated by AT&S but have not demonstrably put personal capital at risk. For Mertin and Steen (both joined within the last 12 months), this is understandable — they may still be building positions or subject to blackout restrictions.
10b5-1 equivalent (Austrian MAR plans): No automatic selling plans disclosed. The Günter Pint sell in February 2026 appears to be a departing executive — no pattern of concern.
| Name | AT&S Holdings | Other Public Co. Holdings | Where Is the Majority? |
|---|---|---|---|
| Dörflinger Foundation | ~18% (~€612M) | Not publicly disclosed | Majority appears AT&S-concentrated |
| Androsch Foundation + AIC | ~17.55% (~€597M) | AIC Androsch International Consulting — private consulting; no significant public holdings disclosed | AT&S-concentrated |
| Michael Mertin | Not disclosed | No public holdings in other companies identified | Unknown |
| Gerrit Steen | Not disclosed | No public holdings identified | Unknown |
| Peter Griehsnig | Not disclosed (22yr employee) | No external board/equity roles identified | Likely AT&S-concentrated |
| Andy Mattes | Not disclosed | Cohu, Inc. board; McKinsey advisory | Spread across multiple roles; AT&S board is unpaid in disclosed terms |
| Tumpel-Gugerell | Small disclosed purchases at AT&S | Former ECB board member; likely multiple other board roles | Not concentrated in AT&S |
The founding bloc (35.6%): Their wealth is overwhelmingly concentrated in AT&S. Dörflinger co-founded the company in 1994 in an MBO. Androsch’s estate made AT&S a central holding over 30 years. This is genuine, irreversible skin in the game — they cannot easily exit without destroying the market.
Management board: The absence of disclosed open-market equity purchases by Mertin and Steen is a yellow flag. Compensation grants (stock options or restricted shares) are standard but do not represent the same conviction as open-market buying. Track until the first disclosed open-market purchase.
AT&S’s subsidiary structure is disclosed in annual reports under IFRS and consists of straightforward operating subsidiaries:
| Entity | Location | Relationship | Business |
|---|---|---|---|
| AT&S China | Shanghai + Chongqing | Wholly-owned production subs | IC substrates + PCBs for Asian market |
| AT&S Malaysia (Kulim) | Kedah, Malaysia | Wholly-owned | ABF FC-BGA substrates |
| AT&S India (Nanjangud) | Karnataka | Wholly-owned | Industrial/auto PCBs |
| AT&S Austria (Leoben, Fehring) | Austria | Operating parent | HDI PCBs + IC substrates |
| Various holding entities | Austria, Netherlands | Standard holding structure | Internal intercompany financing |
No evidence of undisclosed off-balance-sheet entities, IP holding structures, or advisor-controlled vehicles transacting with the public company.
AT&S AG (Vienna — listed, ~38.85M shares)
├── AT&S Malaysia (Kulim — production)
├── AT&S (Shanghai) Co., Ltd.
├── AT&S (Chongqing) Technology Co., Ltd.
├── AT&S India Private Ltd. (Nanjangud)
├── AT&S Austria (Leoben HTB1/2/3, Fehring)
└── AT&S Japan, AT&S USA, AT&S Korea (minimal)Structure is clean, transparent, and operationally logical. No circular ownership, no offshore SPVs, no undercapitalized holding shells. IFRS consolidation is straightforward.
Capital increase dispute (2024): The aborted €450–500M equity raise (planned via Öbag, Austria’s state holding company) created an internal governance fight. Androsch blocked it; Dörflinger supported it; Gerstenmayer (then CEO) was caught in the middle and ultimately forced out. This is governance dysfunction but not fraud or breach of fiduciary duty — it reflects the structural weakness of two large private foundations with conflicting strategic views co-controlling a public company. The resolution (Gerstenmayer exit, new management, board refresh) was a legitimate governance outcome even if the process was messy.
No SEC enforcement actions (AT&S is not a U.S. registrant; no ADR program). No FMA (Austrian financial regulator) enforcement actions identified. No material personal litigation against current management identified.
AT&S publishes a Remuneration Report under the Austrian Corporate Governance Code. Specific figures from the most recent remuneration report (FY2024/25 annual report) were not retrievable in this research pass. Based on comparable Austrian/German industrial companies of similar size:
AT&S’s remuneration policy, per the Austrian CGC: - Short-term incentive (STI): Tied to EBITDA, revenue, and defined strategic milestones — operationally oriented metrics - Long-term incentive (LTI): Multi-year vesting, tied to TSR and/or operational metrics over 3–4 year periods - No discretionary override known to have occurred in FY2025/26 (new management took over during the year)
Grant forensics — limitation: AT&S does not publish DEF 14A (U.S. filing); the Austrian equivalent (Remuneration Report) is in the annual report. Without the full FY2024/25 annual report text, the specific hurdle structures of LTI grants for Mertin and Steen cannot be confirmed. However: - The company’s own guidance for FY2026/27 (€2.1–2.4B revenue, 24–28% EBITDA margin) is ambitious - If LTI hurdles are set at or near this guidance, management is well-aligned with shareholders on the ramp scenario - If hurdles are set materially below this guidance, it would represent an easy layup — to be verified against the FY2025/26 annual report when published (May 2026)
No unusual perks disclosed: No corporate jet personal use, no family-on-payroll disclosures. AT&S is a Leoben, Austria-headquartered industrial manufacturer — not a culture of CEO perk extraction.
| Deal | Year | Price Paid | Subsequent Performance |
|---|---|---|---|
| Kulim campus (greenfield) | 2021–2025 | ~€1B (multi-year capex) | HVM certified May 2025; AMD-anchored; thesis intact |
| Leoben HTB3 (greenfield) | 2022–2025 | ~€300–400M est. (EU co-funded) | Opened Jun 2025; co-financed by EU €500M grant |
| Chongqing (China expansion) | 2015–2020 | ~€300M est. | Operational; decent returns; Chinese PCB market exposure |
| Ansan (Korea divestiture) | 2024 (sold) | Sold for €405M | Removed underperforming/non-core asset; improved balance sheet; timing was excellent |
M&A verdict: AT&S management has primarily done greenfield capex rather than acquisitions. The Kulim and Leoben decisions are the two critical bets — both were made under Gerstenmayer, not Mertin. Mertin inherited them and is now executing. The only major asset sale (Korea) was well-timed and price-maximizing.
| Year | Context | Capex Action | Equity Action | Grade |
|---|---|---|---|---|
| FY2020/21 | AI/semi upcycle beginning | Committed to Kulim greenfield | No new equity | Neutral (right bet, but at cycle start) |
| FY2021/22 | Cycle peak, stock high | Accelerated Kulim construction | No equity (smart) | Green — no equity at peak |
| FY2022/23 | Cycle softening | Continued €800M+ capex commitment | No equity | Yellow — capex commitment at cycle peak was painful |
| FY2023/24 | Trough | Korea sale (€405M) | No equity | Green — smart divestiture at best available price |
| FY2024/25 | Recovery start | Capex reduced to €415M | No equity | Green — capex discipline improving |
| FY2025/26E | Ramp | Capex €200M (revised down from €250M) | No equity | Green — capex peak definitively behind |
Capital Allocation Timing: Neutral-to-Good. The fundamental decision to expand dramatically was bold and has proven directionally correct — the AI substrate demand wave is real. However, the capex commitment was poorly timed relative to the semiconductor cycle, creating leverage stress in FY2022–2024. No equity was issued (excellent), no buybacks were executed (appropriate given leverage). The Korea sale was excellent capital recycling. The overall pattern is: a big cyclical bet, somewhat poorly timed within the cycle, but ultimately correct directionally. Management understood they should not dilute equity; they correctly used debt, asset sales, and institutional grants instead.
| Period | Metric | Initial Guidance | Final Guidance | Actual | Assessment |
|---|---|---|---|---|---|
| FY2023/24 | Revenue | ~€1.6–1.7B (raised from €1.5B) | ~€1.55B (cut Oct 2023) | €1,549M | MISS — guidance cut mid-year |
| FY2023/24 | EBITDA margin | ~25%+ | ~20% | ~17.7% adj. | MISS — significant margin compression |
| FY2024/25 | Revenue | €1.7–1.8B (orig.) | €1.5–1.6B (cut Oct 2024) | €1,590M | NEAR-MISS (at top of revised range) |
| FY2024/25 | Full-year → H1 only | Full-year guidance | Shifted to H1-only disclosure | H1 €846M (beat H1 guide) | Green H1 beat; but abandoned full-year |
| FY2025/26 H1 | Revenue | ~€820M | Maintained | €846M (+3.2% beat) | Green |
| FY2025/26 | Revenue | ~€1.7B | Maintained → lower end FX risk | On track | In progress |
Additionally (FY2022/23): AT&S adjusted medium-term targets (originally FY2025/26 €3B revenue target) rightward by one year to FY2026/27 in March 2023. This was an explicit guidance miss on the long-term plan.
Pattern: Overpromiser on medium-term targets; improving on near-term guidance under new management.
The Gerstenmayer era set ambitious long-term targets (€3B by FY2025/26) that were visionary but proved too aggressive. Two consecutive years of guidance cuts (FY2023/24 and FY2024/25) in the prior period reflect: 1. Over-optimism on the semiconductor cycle recovery timing 2. Over-optimism on yield ramp speed at Kulim 3. External factors: FX headwind (EUR/USD), automotive weakness, Apple order volatility
Under the new Mertin management (May 2025 onward): - The shift to H1-only guidance in FY2025/26 was a deliberate conservatism reset — rather than commit to a full-year number during an uncertain macro environment, management guided only half-years - H1 FY2025/26 guidance: €820M → actual €846M (+3.2% beat) — first clean beat under new management - The Q3 FY2025/26 result (€468M, +18% QoQ) is tracking well ahead of pace
Guidance Tendency: Transitioning from aggressive/overpromising (Gerstenmayer era) to conservative (Mertin era — still early). Only 3 reporting periods under Mertin — cannot yet call a trend, but the signal is positive.
| Date | Statement | Reality | Follow-Through |
|---|---|---|---|
| FY2022/23 | “€3B by FY2025/26, 27–32% EBITDA margin” | Pushed to FY2026/27; margins below target | ❌ (medium-term miss) |
| Oct 2024 | “Volatile ordering behaviour of a key customer” (guidance cut) | Honest attribution — Apple PCB weakness | ✅ (transparent) |
| H1 FY2025/26 | “We exceeded the half-year forecast despite massive FX headwinds” | H1 revenue €846M vs. €820M guide | ✅ |
| Q3 FY2025/26 | “Kulim is in the middle of ramping up” | Q3 revenue €468M (+18% QoQ) | ✅ (ramp visible in numbers) |
| FY2025/26 | “FY2026/27 guidance €2.1–2.4B assumes no further USD depreciation” | USD has depreciated ~10% since Dec 2024; guidance moved to lower end | ⚠️ (transparent hedge, not a miss yet) |
Weasel language present but acceptable: The FX caveat is disclosed prominently, not buried — management is being transparent that the guidance has an embedded FX assumption. This is the correct way to communicate macro-sensitive guidance.
Overall Follow-Through Rate: ~60–65% historically; improving under new management. Credit Mertin for resetting to half-year guidance increments.

Board assessment:
This is a materially improved board relative to the Androsch-dominated prior composition. Key strengths: 1. Hermann Eul (former Intel CTO): Semiconductor technology expertise directly relevant to AT&S’s IC substrate business — this is exactly the right background for oversight 2. Lars Reger (NXP CTO): Active semiconductor industry practitioner; current customer-side perspective on substrate requirements 3. Gertrude Tumpel-Gugerell (former ECB Executive Board): Macro and financial oversight credibility; has made two open-market equity purchases — real skin in the game 4. Regina Prehofer: Finance and audit background appropriate for the oversight role
Georg Riedl: Classified as independent under C-Rule 53 but NOT under C-54 — this means he has a financial or business relationship that falls outside the stricter C-54 independence standard. He is associated with the Androsch foundation (the late Hannes Androsch’s representative). His continued presence is the remaining legacy of the Androsch governance era.
Anti-takeover provisions: No disclosed dual-class shares. No known poison pill. Standard Austrian corporate law applies — founding bloc at 35.6% provides de facto blocking power on most extraordinary resolutions without formal anti-takeover structures.
Shareholder proposals: The 2024 governance crisis (Gerstenmayer forced out by Androsch) is the most significant recent governance event. The resolution — Androsch’s death, new management, board refresh with semiconductor-competent members — is a positive outcome even if the process was messy.
| Dimension | Rating | Key Finding |
|---|---|---|
| Skin in the Game | Yellow | Founding bloc at 35.6% with no selling = strong long-term alignment. Management (Mertin, Steen) have no disclosed open-market purchases — gap to close. |
| Holdings Concentration | Green | Founding bloc wealth overwhelmingly AT&S-concentrated. No competing financial interests identified. |
| Shell / Cross-Holdings | Yellow-Green | Clean structure. One unresolved item: AIC (Androsch consulting firm) historical related-party potential. Androsch deceased — risk reducing. No confirmed material payments. |
| Capital Allocation | Yellow-Green | Correct directional bet (AI substrates); cycle timing was imperfect; excellent on equity discipline (zero dilution over decade). Korea divestiture was smart. |
| Compensation Alignment | Yellow | STI/LTI principles are correct (EBITDA + TSR linked). Specific hurdle structures for new management not yet verified from annual report. |
| Credibility / Follow-Through | Yellow | Two consecutive guidance cuts under Gerstenmayer era; reset under Mertin with H1-only approach; first clean H1 beat. Early but positive. Track: 60–65% historical rate, improving. |
| Governance Quality | Yellow-Green | Board is now genuinely competent and semiconductor-literate (Eul, Reger). Riedl is the remaining Androsch legacy; post-Androsch dynamic is cleaner. |
| Litigation / Enforcement | Green | No FMA actions, no U.S. enforcement, no personal litigation on any current executive. |
| Overall Management Grade | B / Yellow |
AT&S’s management is institutionally adequate for the task but not exceptional. The founding bloc’s concentrated, long-term alignment is the primary governance asset — it prevents both excessive management enrichment and short-termism. The board refresh (Eul, Reger, Mattes, Tumpel-Gugerell) is a genuine improvement and brings semiconductor industry credibility the old board lacked. The key execution risk is that Mertin and Steen are new to AT&S at the most critical inflection in company history, while the person who actually knows how to run these plants (Griehsnig) is the CTO, not the CEO. The governance history suggests a company that benefits from committed founding capital but has historically been willing to sacrifice operational management continuity for board-level political reasons. The test of the new structure is whether Mertin-Steen-Griehsnig can execute the FY2026/27 ramp without a repeat guidance cut. If the first full year under Mertin (FY2025/26, full-year result due May 2026) is delivered at or above the €1.7B / 23% EBITDA guide, the management grade upgrades to B+.
