Here are the 424B prospectus supplements from Amkor Technology Inc (AMKR) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A 424B covers the supplement that carries the terms of a priced offering, so if you follow AMKR and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full AMKR filings page.
Amkor Technology, Inc. has filed a prospectus supplement for the resale of 10,000,000 shares of its common stock by a selling stockholder, 915 Investments, LP. This is a secondary offering, and Amkor will not receive any proceeds from the sale.
The shares are priced at $48.75 per share, implying a public offering size of $487,500,000, with underwriting discounts and commissions of $0.26 per share. The selling stockholder expects proceeds of about $484.9 million before expenses, and has granted Goldman Sachs & Co. LLC a 30‑day option to sell up to 1,500,000 additional shares. Amkor had 247,309,063 shares outstanding as of February 10, 2026.
Amkor Technology, Inc. is offering 10,000,000 shares of common stock for resale by the selling stockholder 915 Investments, LP under a Rule 424(b)(7) prospectus supplement. Amkor will not receive any proceeds from this secondary sale.
The underwriter, Goldman Sachs & Co. LLC, has a 30‑day option to buy up to an additional 1,500,000 shares from the selling stockholder. The transaction reduces, but does not eliminate, the Kim family’s controlling stake; their group is expected to hold about 49.5% of voting shares after the offering, or 48.9% if the option is fully exercised.
The filing also provides preliminary unaudited 2025 results. Net sales were $6.71 billion compared with $6.32 billion in 2024, and net income attributable to Amkor was $373.9 million versus $354.0 million. Total assets were $8.14 billion and long‑term debt $1.28 billion as of December 31, 2025, with cash and cash equivalents of $1.38 billion.
