Mark N. Rogers, who serves as Executive Vice President and General Counsel at Amkor Technology, Inc. (NASDAQ: AMKR), executed a sale of company common stock on April 16, 2026. The transaction involved 5,000 shares sold at $59.43 per share, producing gross proceeds of $297,150.
That sale happened on the same day Mr. Rogers exercised employee stock options to acquire an equal number of shares. He purchased 5,000 shares at an exercise price of $7.40 per share, representing a total cash outlay of $37,000. The exercised options stem from a grant dated June 10, 2019, which vested over a four-year schedule.
The disposition was carried out under a Rule 10b5-1 trading arrangement Mr. Rogers established on August 1, 2025. Following the combined exercise and sale, Mr. Rogers holds 38,904 shares of Amkor Technology common stock outright. In addition to that direct holding, he retains 90,000 derivative shares in the form of employee stock options.
Market action since the transactions has moved Amkor shares higher. The stock has traded up to $69.44 and is cited as trading near a 52-week high of $69.37. Over the past year the share price is noted as delivering a 327% return.
Valuation commentary included with the transaction notes that InvestingPro data indicates Amkor may be trading above its Fair Value, with a price-to-earnings ratio of 46.12. The reference frames the stock relative to a valuation benchmark but does not provide additional investment guidance.
Recent corporate and financial developments for Amkor are also noted. For the fourth quarter of 2025 the company reported earnings per share of $0.69, ahead of an expected $0.44. Reported revenue for the quarter was $1.89 billion, modestly above the forecast of $1.84 billion. In the wake of those results, Needham raised its price target on Amkor to $65.00 from $50.00 while maintaining a Buy rating and citing a positive growth outlook.
Alongside these operational results, the Kim Family - identified as Amkor's largest shareholder - filed a secondary public offering of 10 million shares priced at $48.75 apiece. That offering is being conducted through 915 Investments, LP, and the company will not receive proceeds from the sale. Goldman Sachs & Co. LLC has been granted a 30-day option to purchase an additional 1.5 million shares in connection with the offering.
