SVP Global Sales Donghyun Thomas Hwang sold 2,620 shares for $1.0M via 10b5-1 plan on 2026-06-25

Donghyun Thomas Hwang (SVP, Global Sales) executed 12 separate sales totaling 2,620 shares for $1,005,732.29 as part of a pre-arranged 10b5-1 trading plan adopted on 2025-08-11. The transactions spanned prices from $367.30 to $391.94, with a blended average price of $383.87. This represents an 8.1% reduction from his pre-transaction holdings of 32,376 shares (resulting in 29,756 shares post-transaction). Because this transaction is scheduled under a 10b5-1 plan rather than discretionary, timing considerations do not apply to this specific filing. The sales occurred when the stock was trading at $372.59 current price, positioned 11.1% below its 52-week high of $418.90, while the company reported strong near-term momentum with +67.8% 90-day appreciation and positive fundamentals including +32.6% annual revenue growth to $289.0M and $46.3M in net income, though note the company was unprofitable over its most recent full fiscal year.

SVP Global Sales Hwang sells 3,718 shares for ~$1M in nine separate transactions, continuing a pattern of liquidation with historically poor timing.

Hwang Donghyun Thomas, the company's Senior Vice President of Global Sales, disposed of roughly 3,700 shares across nine separate trades for approximately $1M, reducing his direct stake from about 38,600 shares to 34,886 shares. This is his ninth open-market sale in the past three years and his sixth sale of MTSI stock specifically, with no open-market purchases in that entire window—a pattern of consistent liquidation with zero buying activity. Looking at his prior sales at MTSI, every single one saw the stock rise afterward both in the near term and over longer horizons, meaning his previous exits were consistently poorly timed. The stock has risen sharply recently and currently trades modestly above its 52-week midpoint, while the company posted a profitable quarter but remains unprofitable on an annual basis. Taken together, this sale extends Hwang's track record of selling at the wrong time in a stock that has rebounded significantly, and the exclusive focus on selling—never buying—over three years suggests he is managing his holdings downward rather than expressing conviction in the company.

SVP Thomas Hwang sold 5,274 shares for $1,192,260 at MTSI; post-transaction holds 38,604 shares.

Hwang Donghyun Thomas, SVP of Global Sales, executed 10 separate sales on 2026-02-02 totaling 5,274 shares (12.0% of his pre-transaction holdings) for $1,192,260, with a blended average price of $226.06. The stock currently trades at $215.03, down 5.9% from its 52-week high of $228.56, though it has gained 25.9% over the prior 30 days and 28.8% over 90 days. This sell occurs during a period of strong stock appreciation but after the stock has peaked near its 52-week high. His same-ticker history shows 5 prior sales in late 2023, none of which were well-timed at the 90-day mark—the stock subsequently rose after those earlier sells. The company's financial position includes $252.1M in latest-quarter revenue and $36.5M net income, with 32.6% annual revenue growth, though full-year net income was negative. The significance of this transaction rests on the timing relative to the stock's recent high and the absence of a pattern of well-timed exits in his prior MTSI trades.
