Amkor Technology: AI Tailwinds Support Earnings as Capex Cycle Accelerates

al debt. As of June 30,

the company had $2.5bn of cash and short-term investments, $3.6bn of total liquidity, and

$2.5bn of total debt. Net debt is essentially zero, and management reported gross debt/

EBITDA of 1.8x. The convert meaningfully improves near-term flexibility and reduces

the need for a more urgent HY market transaction, particularly given expected customer

prepayments, potential government incentives, and ongoing operating cash flow

generation.

• Free cash flow is negative, but this is investment-cycle driven rather than operating

deterioration. First-half operating cash flow was $382mn versus $688mn of PP&E

payments, implying negative free cash flow of roughly $307mn before considering the

large increase in capex payables. The company’s core earnings trajectory is improving

quickly, but cash flow will remain pressured as Arizona and other advanced packaging

capacity buildouts accelerate. From a credit perspective, this is acceptable so long as

customer commitments remain firm, utilization ramps as expected, and management

maintains discipline around shareholder returns.

• Leverage increased, but the balance sheet remains strong. Gross debt rose materially

after the $1.15bn convertible issuance, yet the balance sheet remains in good shape given

$2.5bn of cash and short-term investments and $3.6bn of liquidity. The company has

effectively pre-funded a portion of its capex cycle with low-cost capital. While reported

debt/EBITDA of 1.8x is no longer negligible, net leverage remains minimal and should

remain manageable if EBITDA continues to scale with AI/HPC growth. The key watch

item is whether capex, customer prepayments, and incentive timing create any liquidity

gaps in 2027.
