Amkor Technology CFO Megan Faust Sells 1,000 Shares Under Pre-Arranged Trading Plan

CFO Share Sale Details and Timing

Megan Faust, who serves as Chief Financial Officer of Amkor Technology Inc., executed a sale of 1,000 common shares on July 14, 2026. The transaction was reported in a regulatory filing dated July 16, 2026. The sale price was disclosed at $69.91 per share, representing a routine equity transaction by a senior company executive. This disclosure is required under Section 16 of the Securities Exchange Act of 1934, which mandates reporting of beneficial ownership changes by corporate officers and directors.

The filing indicates that Faust remains a substantial shareholder in the company following the transaction. Her direct beneficial ownership following the reported sale stands at 136,105 shares. This retention of significant company equity demonstrates continued financial alignment with Amkor Technology shareholders. The transaction itself constituted only a modest reduction in her overall shareholding position.

Rule 10b5-1 Trading Plan Framework

The share sale was executed pursuant to a Rule 10b5-1 trading plan that Faust adopted on February 17, 2026. Such pre-arranged trading plans allow company insiders to establish written instructions for purchasing or selling securities at predetermined times and prices, removing concerns about trading based on material nonpublic information. The Rule 10b5-1 framework provides an affirmative defense against insider trading liability when properly executed and documented.

By adopting a trading plan in advance of actual transactions, insiders demonstrate compliance with securities regulations designed to protect market integrity. The plan was established approximately five months before the July 2026 sale reported in this filing. This advance planning and formal structure reflect standard corporate governance practices among public company executives managing their equity compensation and shareholding positions.

Beneficial Ownership Position After Transaction

Following the sale of 1,000 shares, Faust's directly owned beneficial ownership in Amkor Technology totaled 136,105 shares. This represents her direct holdings, meaning shares registered in her name or held in accounts where she exercises investment control. The filing confirms this ownership is held in direct form rather than through indirect arrangements such as trusts, family entities, or other intermediate ownership structures.

The company did not disclose the total value of Faust's remaining shareholding or whether she holds any additional shares indirectly through other entities or arrangements. Her direct ownership position indicates a material stake in the company's performance and suggests ongoing confidence in Amkor Technology's business prospects. The magnitude of her shareholding aligns with typical equity incentive arrangements for senior financial executives at major semiconductor equipment and services providers.

Regulatory Compliance and Filing Requirements

The disclosure was filed as an official Form 4 statement of changes in beneficial ownership with the Securities and Exchange Commission. This regulatory form is required under Section 16(a) of the Securities Exchange Act of 1934 and must be filed within two business days of the transaction occurring. The filing was completed on July 16, 2026, two calendar days after the transaction date of July 14, 2026.

The reporting requirement applies because Faust holds the position of Officer (specifically Chief Financial Officer) at Amkor Technology, making her a company insider subject to beneficial ownership reporting obligations. The Form 4 filing is a standard disclosure mechanism that provides transparency to investors regarding equity transactions by senior management. The filing includes formal certification that the information provided is accurate and complete, with intentional misstatements or omissions constituting federal criminal violations under applicable securities laws.

Amkor Technology's Business Context

Amkor Technology Inc. is a major provider of semiconductor packaging, testing, and related services serving the global semiconductor industry. The company operates facilities and provides services across multiple geographic regions and customer segments. As Chief Financial Officer, Megan Faust holds responsibility for the company's financial planning, accounting, investor relations, and capital management functions, making her one of the most senior executives in the organization.

The semiconductor packaging and testing industry serves as a critical component of the global electronics supply chain, processing semiconductor devices for a wide range of end-market applications. Companies in this sector maintain significant capital intensity and are sensitive to semiconductor industry cycle dynamics. Amkor's stock represents an equity security that trades on the NASDAQ exchange, subject to all reporting and disclosure requirements applicable to publicly traded U.S. companies.

Insider Trading Plan Adoption in February 2026

The trading plan underlying this transaction was formally adopted by Faust on February 17, 2026, approximately five months prior to the July 14, 2026 share sale. Adoption of a Rule 10b5-1 trading plan must occur when the executive does not possess material nonpublic information about the company. Once adopted and documented, such a plan becomes binding and removes questions about whether subsequent trades were timed based on confidential information.

The pre-arranged plan structure is commonly used by executives to manage their equity holdings systematically and in compliance with securities regulations. By establishing predetermined sale instructions months in advance, executives demonstrate that individual trades are part of a predetermined program rather than opportunistic responses to favorable market conditions or unfavorable company developments. The February adoption date provides substantial advance notice and documentation of the trading program governing this July transaction.

Transaction Mechanics and Reporting Structure

The transaction involved a sale, indicated by the code "S" in the filing's transaction code field, of 1,000 shares at $69.91 per share. The sale was direct beneficial ownership, indicated by the "D" designation, meaning the shares were held directly by Faust rather than through intermediary entities. No derivative securities or options were involved in this particular transaction; it represented a straightforward equity sale of common shares.

The reporting structure captured the transaction details in Table I of the Form 4, which covers non-derivative securities acquired or disposed of. The filing included no Table II entries, as the transaction involved no derivative securities such as puts, calls, warrants, or options. The clear and straightforward reporting format reflects the relatively simple nature of the equity transaction and Faust's direct ownership of the securities being sold.

Attorney-in-Fact Signature Authority

The Form 4 was signed by Mark N. Rogers, identified as Attorney-in-Fact for Megan Faust, on July 16, 2026. The use of an attorney-in-fact to execute the filing indicates that Rogers held power of attorney from Faust to sign regulatory documents on her behalf. This is a common practice among executives who delegate certain administrative and compliance responsibilities to legal representatives or corporate counsel.

The signature by attorney-in-fact does not diminish the legal validity or enforceability of the filing or the certifications contained within it. The reporting person (Faust) remains legally responsible for the accuracy and completeness of the disclosed information. The filing constitutes an official SEC submission and provides the same legal force and effect as if signed directly by the executive herself.

Market Implications and Investor Considerations

The immediate share price impact was not clear from available public information at the time of the transaction or filing. Insider share sales by executives are routine occurrences at public companies and do not necessarily indicate negative views about company prospects. Executives may sell shares for various personal financial reasons including portfolio diversification, tax planning, or planned capital expenditures, independent of their views on company performance.

Investors monitoring insider trading activity at Amkor Technology may track whether additional Form 4 filings from executives emerge in subsequent periods. The pre-arranged nature of this transaction and Faust's retention of a substantial equity stake (136,105 shares) may be factors considered when evaluating whether the sale reflects any material change in management's outlook. Historical trading patterns and the timing of such filings relative to company earnings announcements and other disclosure events can provide additional context for investors assessing insider activity.
