The People

Governance grade: B. Auros is a parent-controlled (FST group ~50.8%) Korean small-cap with a founder-CEO whose personal stake matters, a technically elite Co-CEO whose personal stake does not, and the minimum statutory board the Korean Commercial Code allows — no audit committee, one outside director, one part-time statutory auditor. Compensation is modest, related-party cash flow leaks to the parent landlord, and options issued at the IPO peak are deeply out of the money. Nothing is broken; nothing is best-in-class.

Governance Grade: B

The People Running This Company

Five people matter: two Co-CEOs, one veteran inside director, the CFO-equivalent, and the new outside director. The founder still runs operations; the technical heavyweight (ex-Samsung EUV pioneer) is the bet on the next product cycle. The new outside director replaces a prior one who attended zero board meetings — a clean-up that took two years to happen.

Lee Jun-Woo (Co-CEO, founder) — Pusan National physics graduate (1993). Built the company after stints at Hyundai Information Technology and Nanometrics Korea. Re-elected five times; current term to 2028. The continuity bet — and the only individual with non-trivial alignment (1.64%, roughly $2.7 m at year-end close).

Choi Seong-Won (Co-CEO, technical) — UIUC, Stanford, UCLA PhD in mechanical engineering. Led Samsung's world-first EUV active-pellicle mass-production project in 2017 before moving to FST and then to Auros in 2023. This is the most credentialed hire Auros could plausibly make for the HBM/EUV transition. He owns 1,500 shares.

Min Kyung-Jin (Outside Director, since Mar 2025) — Mirae Asset IB veteran. Replaced Im In-Sang, the prior outside director, who attended 0 of 12 board meetings in 2025 before being cycled out. Min has hit 100% attendance since joining.

What They Get Paid

Pay is modest in absolute terms and relative to peers. Five recipients shared $495 k in FY2025 against an AGM-approved $1.38 m ceiling — payouts at 36% of the cap signal pay discipline. The Co-CEOs and the senior advisor split $454 k three ways (~$151 k each). Adding 23 non-registered executives, total executive cash compensation was $2.5 m — roughly 2.7% of FY2025 revenue.

Both option grants are deeply out of the money. The 2021 IPO-era grants struck at $34 expire in March 2026 — they will almost certainly go unexercised. The 2024 grant to Choi at $24 needs a 37% rally to break even and is exercisable from March 2026. Option grants are not currently providing the alignment they were intended to deliver.

Are They Aligned?

This is the hard question. Auros is a controlled subsidiary, not a founder-led independent. The economic alignment that matters is FST's, not management's.

Control vs alignment. FST Co. directly holds 33.54%; affiliated CM Technology holds 17.27%. Together with management, the control block is 54.40%. FST's chairman (Jang Myeong-Sik) simultaneously sits as CEO of Korea Lam Research — an unusual concurrent role that ties the parent's leadership to a major customer/equipment ecosystem and should be watched, even though it is disclosed.

Insider trading. The only individual transaction in FY2025 was CFO-equivalent Yu Jae-Man trimming 2,000 shares ($35 k at year-end prices). Immaterial. No insider buying either.

Treasury / buybacks. The company holds 1.42% of shares as treasury (133,100 shares from two trust-purchase programs in 2023 and 2024). Officially earmarked for employee compensation, not retirement — so treat as a deferred dilution wash, not a return-of-capital signal. No buyback announced for 1H 2026.

Related-party economics — the largest single concern.

The Dongtan-1 main factory is leased from parent FST. Annual lease + welfare payments to FST run roughly $0.88 m — small in absolute terms but a structural cash leak to the controlling shareholder. The $3.75 m CM Technology asset sale netted into Auros, partially offsetting. Disclosure is clean; the economics are slightly tilted upward toward the parent.

Dilution. Outstanding common ~9.37 m shares with negligible change. Total option pool: 187 k shares net of cancellations, or ~2.0% potential dilution if fully exercised at OTM strikes (which is unlikely). ESOP holds 0.23%. Dilution is a non-issue for now.

Skin-in-the-game score: 5.5 / 10. Founder Lee has meaningful skin ($2.7 m personal stake); Co-CEO Choi has essentially none in cash terms and his options are out of the money. The economic anchor is FST's ~51% controlling stake — substantial but it is parent-shareholder alignment, not management-shareholder alignment. Outside directors and the statutory auditor hold zero shares.

Board Quality

The board has exactly the structure the Korean Commercial Code requires for a sub-trillion-won company — and not one item beyond it. Three inside directors, one outside director, one non-standing statutory auditor (no full audit committee). This is formal independence, not real independence.

What this board is good at. Deep technical and customer knowledge from the three insiders — Lee (founder operator), Choi Seong-Won (Samsung EUV), Choi Yong-Geun (ex-SK Hynix process management). The new outside director Min adds capital-markets perspective. The statutory auditor Lee Pyeong-Gu has audit-committee chair experience at Seoul Guarantee Insurance — better than the typical part-time appointee.

What it lacks.

• No audit committee. Reliance on a single non-standing statutory auditor is the legal minimum, not best practice. For a company doing ~$94 m in revenue with material related-party flows to its parent, an audit committee with at least two independent members would be appropriate.
• One outside director. Two would force genuine deliberation; one allows the board to operate as effectively an FST-affiliated inside body.
• Two of the three insiders trace to FST. Choi Seong-Won and Choi Yong-Geun both came via FST executive positions before joining Auros — they are technically excellent but they are FST people.
• Joint-CEO structure (각자 대표이사) — either CEO can bind the company. Workable when the two trust each other; raises accountability questions if they disagree.

The Verdict

Governance grade: B. Honest, modestly compensated, technically capable, transparently disclosed — and structurally exactly what a parent-controlled KOSDAQ small-cap looks like when nothing has gone wrong yet.

Governance Grade: B

Strongest positives. Founder-CEO with 16 years on the job and meaningful personal stake. An elite technical Co-CEO who built EUV pellicle mass production at Samsung. Compensation runs at one-third of the approved cap. Audited related-party disclosures are clean. No regulatory actions, no insider drama, no aggressive dilution. The new outside director and statutory auditor both bring genuinely useful resumes.

Real concerns. The structure is parent-controlled, not founder-controlled — FST captures ~51% of any value created plus collects $0.88 m/year in lease and welfare payments. The audit-committee gap and one-outside-director board are legal-minimum governance. Co-CEO Choi has essentially no personal economic stake and his options are out of the money. The tolerance of a 0%-attendance outside director for a full year before replacement says something quiet about board culture.

What would upgrade it to A−. Establishing an audit committee, adding a second genuinely independent outside director, repricing or re-issuing options closer to spot to restore alignment for the technical CEO, and shifting related-party payments toward arm's-length (e.g., acquiring or replacing the FST-leased factory).

What would downgrade it to C. Material related-party transactions outside the disclosed lease/welfare envelope; an FST-friendly capital action that disadvantages minority holders (e.g., a low-ball tender or an FST-driven equity issuance); the founder reducing his stake without replacement; or a recurrence of the dormant-outside-director pattern.
