Second Quarter 2026 Reporting Period and Filing Details

Amkor Technology disclosed its quarterly financial performance in a comprehensive filing submitted to the Securities and Exchange Commission on July 28, 2026. The filing covered the second quarter period from April 1, 2026 through June 30, 2026, as well as the six-month period from January 1, 2026 through June 30, 2026. This disclosure included comparative financial data from the corresponding quarters and six-month periods in 2025, allowing investors to assess year-over-year performance trends in the semiconductor packaging and test industry.

The company's financial disclosures encompassed detailed balance sheet information as of June 30, 2026, compared with year-end 2025 figures as of December 31, 2025. This dual-period presentation provides investors with insight into how Amkor's financial position evolved during the first half of 2026. The filing also included subsequent event disclosures dated July 28, 2026, indicating material developments that occurred after the June 30, 2026 period end but prior to the filing date, which investors should monitor for potential impacts on future operational and financial performance.

Business Segments and Product Portfolio Structure

Amkor operates two primary reportable segments that organize its business around product technology and market positioning. The Advanced Products segment encompasses higher-margin, technology-intensive offerings targeting customers requiring cutting-edge packaging and test solutions. The Mainstream Products segment serves customers whose applications prioritize cost-effectiveness and established manufacturing processes. This segmented approach allows the company to serve diverse customer requirements across the semiconductor industry while maintaining distinct operational and strategic focuses for each segment.

The company's revenue is further analyzed by sales channels that reflect its major end-market customers and applications. These channels include Communications, Computing, Automotive and Industrial, and Consumer Goods segments. The filing indicates that Amkor tracks revenue concentration across these diverse channels, allowing management and investors to understand which market verticals drive the company's growth and profitability. The breadth of Amkor's end-market exposure suggests the company serves a diversified customer base across multiple industries, which may help mitigate risk from any single market downturn.

Capital Structure and Shareholder Equity

Amkor's capital structure reflects its status as a publicly traded semiconductor services company with common stock issued and outstanding as of June 30, 2026. The filing discloses detailed equity composition including common stock, additional paid-in capital, retained earnings, accumulated other comprehensive income, and treasury stock accounts. The company also maintains noncontrolling interests in consolidated subsidiaries, indicating that Amkor operates through a structure that includes subsidiaries in which other entities hold partial ownership stakes. This structure is common among multinational semiconductor companies with operations across multiple countries and business lines.

The filing documents significant convertible debt, specifically referencing Convertible Senior Notes Due July 2031. This convertible obligation represents a financing arrangement that allows Amkor to access capital markets while offering investors conversion rights into the company's common stock under specified conditions. The presence of convertible debt as of June 30, 2026 signals that Amkor maintains a blended capital structure combining traditional debt instruments with equity-like conversion features. Such instruments are frequently used by technology and semiconductor companies seeking to manage their weighted average cost of capital while preserving debt covenants and financial flexibility.

International Operations and Foreign Investment Support

Amkor's operational disclosure includes references to a Foreign Direct Investment Cash Support Agreement as of June 30, 2026, extending through 2031. This agreement suggests that Amkor maintains manufacturing or significant operational presence in foreign jurisdictions and has secured government financial support mechanisms to sustain those operations. Such agreements are common in semiconductor manufacturing, where countries compete to attract advanced fabrication, packaging, and test capacity by offering tax incentives, grants, or direct financial support to qualified companies. The five-year term of this agreement indicates Amkor's commitment to maintaining or expanding foreign operations through at least 2031.

The filing also references letters of credit issued for customer advance payments received as of June 30, 2026, with a subsequent event disclosure dated July 28, 2026 indicating modifications to these arrangements. Letters of credit in the semiconductor industry typically secure customer advance payments, ensuring that customers receive specified performance or contractual obligations from Amkor. These financial instruments are standard practice when customers prepay for future manufacturing capacity or services, providing security that contractual commitments will be honored.

Stock Compensation and Employee Incentive Programs

Amkor disclosed information regarding stock compensation plans active during the first half of 2026. The filing indicates that the company utilizes equity-based compensation mechanisms for employees, consistent with industry practice among publicly traded semiconductor companies. Stock compensation plans typically include stock options, restricted stock units, and performance shares designed to align employee interests with long-term shareholder value creation. The company's disclosure of stock compensation activity during both the second quarter and six-month periods suggests ongoing issuance of equity-based awards to employees and potentially service providers.

These equity compensation arrangements represent a significant component of employee compensation in the semiconductor industry, where talent acquisition and retention are critical competitive factors. By offering stock-based incentives, Amkor seeks to attract engineering, operational, and management talent while fostering a culture of ownership and performance accountability among its workforce. The ongoing nature of these programs, as evidenced by disclosures across multiple reporting periods, indicates that Amkor maintains active recruitment and retention efforts in the competitive semiconductor labor market.

Investment Tax Credits and Government Incentives

Amkor's financial disclosures include references to Investment Tax Credits as of June 30, 2026 and December 31, 2025. These credits represent government-sponsored tax incentive programs that reward companies for qualifying capital investments in manufacturing facilities or research and development activities. In the semiconductor industry, investment tax credits are frequently available from both federal and state governments seeking to promote domestic semiconductor manufacturing, packaging, and test capacity. Amkor's disclosure of these credits indicates the company qualifies for and actively pursues available government incentive programs to support its capital investments.

The presence of investment tax credits on Amkor's balance sheet as an asset suggests these credits represent future tax reduction opportunities or, in some jurisdictions, refundable claims against current or future tax liabilities. The filing also references grant receivables as of June 30, 2026 and December 31, 2025, indicating that Amkor has secured government grants or direct financial support for qualifying activities. These incentive programs effectively reduce Amkor's effective tax rate and improve cash flow, making them material factors in the company's overall financial performance and cash generation capability.

Convertible Debt and Debt Maturity Schedule

Amkor maintains Convertible Senior Notes Due July 2031, representing a significant financing obligation that comes due in approximately five years from the June 30, 2026 balance sheet date. The filing discloses these notes with conversion features and maturity terms extending into 2031. Convertible notes are hybrid securities that provide creditors with fixed income cash flows while preserving the potential to convert into common stock if the company's share price appreciates substantially. This structure allows Amkor to access debt capital at lower interest rates than traditional bonds while offering investors equity upside participation.

The presence of convertible debt on Amkor's balance sheet reflects the company's capital structure strategy and its ability to access convertible debt markets. As of June 30, 2026, investors should monitor whether the company's stock price and business performance make conversion more or less likely by July 2031. If the company experiences strong revenue and earnings growth, conversion becomes increasingly probable, which would effectively convert debt to equity. Conversely, if the company faces operational challenges, the notes would likely be repaid in cash at maturity, creating a significant liquidity requirement approximately five years forward.

Balance Sheet Composition and Working Capital

Amkor's balance sheet as of June 30, 2026 reflects the company's asset base, liabilities, and shareholder equity positions. The filing discloses current and non-current assets alongside current and non-current liabilities, providing a comprehensive view of the company's financial position. Current assets and current liabilities are particularly important for assessing working capital management and the company's ability to meet short-term obligations. The filing references accrued liabilities, which represent expenses incurred but not yet paid, suggesting Amkor manages typical operating payables and accrued compensation obligations consistent with semiconductor manufacturing operations.

Other current assets disclosed in the filing may include prepaid expenses, customer receivables, inventory, and cash equivalents. These assets represent the operational liquidity available to fund Amkor's ongoing manufacturing and service delivery activities. The balance sheet structure indicates that Amkor maintains sufficient working capital to support its Advanced Products and Mainstream Products segments across multiple geographic and customer markets. Investors analyzing Amkor's financial position should focus on working capital trends, operating cash flow generation, and the company's ability to fund capital investments in manufacturing facilities and equipment required to serve growing semiconductor packaging and test demand.

Subsequent Events and Post-Period Developments

The filing includes subsequent event disclosures dated July 28, 2026, indicating material developments that occurred after the June 30, 2026 balance sheet date but before the filing was submitted. Specifically, the company disclosed modifications to letters of credit issued for customer advance payments and updates regarding the Foreign Direct Investment Cash Support Agreement. These subsequent events suggest that Amkor entered into new arrangements or revised existing agreements with significant implications for its operations and financial position. Investors should carefully review these developments to understand how they might affect future working capital management and international operational capacity.

Subsequent event disclosures are critical for investors because they often signal material changes in business relationships, financing arrangements, or operational capabilities that occur after the balance sheet date but remain pending as of the filing date. In Amkor's case, modifications to customer advance payment arrangements and foreign investment support agreements suggest the company is actively managing its operational footprint and customer relationships. These developments may indicate expansion of manufacturing capacity in targeted foreign jurisdictions or refinement of customer financing structures to better align with Amkor's capital allocation priorities.

Segment Performance and Product Portfolio Metrics

The filing provides detailed revenue and operational metrics broken down by reportable segments and sales channels for both quarterly and six-month periods in 2026 compared with 2025. This segmented reporting allows investors to assess which product lines and end markets are driving growth and profitability. The disclosure of revenue by sales channel—Communications, Computing, Automotive and Industrial, and Consumer Goods—provides transparency regarding Amkor's exposure to secular trends in each vertical market. For example, the Communications channel may reflect demand for semiconductor packaging solutions in wireless infrastructure and 5G deployment, while the Computing channel encompasses data center, artificial intelligence, and client computing applications.

The Automotive and Industrial sales channel reflects Amkor's exposure to automotive electrification, autonomous vehicle development, and industrial automation trends. The Consumer Goods channel encompasses smartphones, tablets, wearables, and other consumer electronics applications. By reporting revenue and concentration metrics across these distinct channels, Amkor enables investors to understand which end markets represent growth opportunities and which may face headwinds. The company's diversification across these four major channels provides some insulation from cyclical downturns in any single market, though concentration in high-growth areas like Computing and Communications offers significant upside potential if those markets expand faster than the broader economy.
