Will Amkor's debt-to-EBITDA ratio exceed 2.0x by year-end 2026?

Starting from 1.2x with $1.4B debt and $1.16B EBITDA. The $2.5B-$3.0B CapEx plan funded by $2.0B cash, operating cash flow (~$380M baseline), and new debt. If Amkor draws down cash to the $500M floor ($1.5B drawdown), that leaves $1.0B-$1.5B to be financed via debt. Adding $1.0-1.5B in new debt brings total debt to $2.4-$2.9B. Meanwhile, EBITDA could compress to $1.0-1.1B on margin pressure from depreciation. That puts the ratio at 2.2-2.9x. However, management has shown sophisticated capital planning and may optimize the mix — customer prepayments, Japan debt markets, and creative financing could keep net leverage lower. Also, the $1B revolver provides flexibility without permanent leverage. The math suggests breaching 2.0x is plausible.

Key assumptions: (1) Operating cash flow ~$380-400M in 2026, (2) CapEx $2.5-3.0B, (3) Cash drawdown from $2.0B to $500M floor = $1.5B, (4) Financing gap: $2.75B midpoint - $1.5B cash - $0.39B OCF = $0.86B in new debt needed. If management uses revolver + term loan, total debt goes to ~$2.3B. EBITDA: if revenue grows to $7.2-7.5B but gross margin compresses to 13%, EBITDA could be $1.1-1.2B. Ratio: $2.3B / $1.15B = 2.0x. It's right at the threshold. The outcome depends on the precise mix of cash drawdown, financing timing, and EBITDA performance. Essentially a coin-flip scenario for the exact 2.0x threshold.

The CFO proactively extended the debt maturity profile in 2025 (replaced $600M revolver with $1B, did $500M term loan, issued $500M notes). This suggests management is preparing to add leverage and is comfortable doing so. The $1B revolver is specifically designed for temporary draws during construction. If revolver draws of $500-700M occur in 2026 (likely given CapEx timing), total debt could reach $1.9-2.1B. With EBITDA flat to slightly down ($1.05-1.16B), the ratio could be 1.7-2.0x. Revolver draws are temporary but would show up in year-end leverage. Customer prepayments provide an alternative to debt but their magnitude is unknown. Close to 50-50.

This is genuinely uncertain. The math for both above and below 2.0x is plausible depending on assumptions. If management aggressively uses the revolver and term debt to fund front-loaded CapEx, year-end debt could easily reach $2.3-2.5B. With EBITDA at $1.1B, that's 2.1-2.3x. Alternatively, if customer prepayments are substantial (undisclosed amount), cash drawdown is managed carefully, and some CapEx shifts to Q1 2027, leverage could stay at 1.8-1.9x. The outcome hinges on financing and CapEx timing decisions that are at management's discretion.

The proactive balance sheet management (maturity extension, facility upsizing) signals management is comfortable with temporary leverage increase. The key question is whether year-end 2026 catches the peak leverage or if the peak occurs mid-year. If Arizona construction spending peaks in H1-H2 2026 and equipment is front-loaded in H1, the cash burn peaks mid-year. If CHIPS Act disbursements begin even modestly in H2, and H2 revenue ramp improves cash generation, year-end leverage may be slightly below the intra-year peak. Probability near 50% with slight lean toward staying below 2.0x given management's active balance sheet management.

I lean slightly above 50% because the scale of the cash consumption is enormous: $2.5-3.0B in CapEx versus $380M in OCF. Even drawing down $1.5B in cash leaves a $600M-$1.1B financing gap. Management has the tools to fill it (revolver, Japan debt, customer prepayments), but the aggregate effect will likely push leverage above 2.0x temporarily. The question is specifically about year-end, and the combination of peak construction spending and front-loaded equipment makes this the highest-leverage point in the cycle.

Starting 1.2x with massive CapEx ahead. New debt needed to fund gap after cash drawdown. EBITDA may compress. Math supports breaching 2.0x but management actively managing. Near coin-flip.

The $2.5-3.0B CapEx versus $2.0B cash and $380M OCF means $600M-$1.1B in new debt. Total debt ~$2.0-2.5B against EBITDA of ~$1.1-1.2B = 1.7-2.3x range. 2.0x threshold falls within the plausible range. Slight lean toward YES given front-loaded spending.

Management has shown sophisticated capital planning. Customer prepayments and Japan debt may reduce need for high-cost leverage. H2 revenue ramp helps cash generation. Slight lean toward staying below 2.0x given active management, but close to 50-50.
