Current state

Year-over-year changes (FY2024 → FY2025)

| Metric | FY2024 | FY2025 | Change | |--------|--------|--------|--------| | Revenue ($M) | 6,317.7 | 6,708.0 | ▲6.2% | | Operating margin (%) | 6.9 | 7.0 | ▲10 bps | | Net income attributable to Amkor ($M) | 354.0 | 373.9 | ▲5.6% |

FY2025 revenue grew $390.3M to $6,708.0M. The computing end market grew 16% driven by AI-related PC devices and networking infrastructure. Automotive and industrial rose 8% on ADAS content. Consumer and communications end markets grew 9% and 1%, respectively. Gross margin compressed 80 basis points to 14.0% from 14.8% in FY2024, primarily due to increased overhead and employee compensation costs and the Vietnam Facility ramp. SG&A dropped $27.3M (8.2%) to $304.5M, partly because a $32.4M cash receipt related to the Nanium insolvency (Nanium Insolvency Receipt) reduced expenses in 2025. That same receipt boosted operating income, explaining the modest operating margin improvement despite gross margin compression. (10-K FY2025, filed 2026-02-20.)

Operating cash flow was essentially flat at $1,095.6M versus $1,088.9M in FY2024. Capital expenditures stepped up to $904.6M (13.5% of net sales) from $743.8M (11.8%) in FY2024, reflecting Arizona Facility construction and advanced packaging equipment investments. As of December 31, 2025, total debt was $1,445.2M with $162.4M due within 12 months; cash and short-term investments totaled $1,991.4M — leaving net cash of approximately $546M. Quarterly dividend was raised 1% to $0.08352 per share in November 2025; total dividends paid in FY2025 were $81.9M. (10-K FY2025, filed 2026-02-20.)

Q3 2025 (10-Q, filed 2025-10-28) showed net sales of $1,987.0M for the quarter, up 6.7% from $1,861.6M in Q3 2024, with nine-month revenue of $4,819.9M vs. $4,688.6M. Q1 2026 revenue (reported 2026-04-27) was approximately $1.69B, representing approximately 27% year-over-year growth, beating estimates with GAAP EPS of $0.33. Q2 2026 guidance is EPS $0.42–$0.52, with the Arizona Facility ramp expected to dilute operating margins in the near term. (8-K Q1 2026, filed 2026-04-27; 10-Q Q3 2025, filed 2025-10-28.)

Open questions

  1. Arizona Facility dilution: Management guided Q2 2026 EPS of $0.42–$0.52, citing near-term margin dilution from the Arizona ramp. How much operating margin compression is embedded in 2026 guidance, and when does Arizona reach breakeven utilization? The 10-K discloses CHIPS Act award of up to $407M but notes no funds received as of December 31, 2025. Construction milestones and clawback conditions need monitoring. (10-K FY2025, filed 2026-02-20.)

  2. CHIPS Act funding timing: The Direct Funding Agreement contains representations, warranties, covenants, and events of default including clawback provisions. No CHIPS Act funds received as of year-end 2025. When will disbursements begin, and what construction milestones trigger them? An investment tax credit rate increase from 25% to 35% (OBBBA, July 2025) applies to qualified property placed in service after 2025 — quantifying the benefit requires the full 2026 capex plan. (10-K FY2025, filed 2026-02-20.)

  3. Vietnam Facility ramp completion: The Vietnam Facility opened in 2024 and caused ~$16M in incremental start-up costs in 2024; gross margin compression persisted into 2025 due to its early-stage ramp. By what quarter does Vietnam reach target utilization? Utilization rates by geography are not separately disclosed. (10-K FY2025, filed 2026-02-20.)

  4. Customer concentration: Amkor serves IDMs, fabless companies, and OEMs globally. Apple and a small number of other large semiconductor customers likely represent a substantial portion of revenue, but customer concentration disclosures need verification in the full 10-K notes. A loss of any lead customer would materially affect results. (10-K FY2025, filed 2026-02-20.)

  5. Nanium receipt non-recurrence: The $32.4M Nanium Insolvency Receipt reduced SG&A in FY2025, boosting operating income. This is a one-time item. FY2026 SG&A comps will face a headwind of approximately $32M absent another such receipt. (10-K FY2025, filed 2026-02-20.)
