Insider transaction details
Oliver K. Mihm, who serves as executive vice president and chief operating officer at Plexus Corp., sold a total of 11,767 shares of the company’s common stock across transactions on February 17 and 18, 2026, for roughly $2.36 million. The sales were executed at a price of $198.785 on February 17 and within a narrow band of $201.40 to $201.41 on February 18.
SEC filing and tax-related disposition
According to a Form 4 filing with the Securities and Exchange Commission, Mihm also disposed of 2,048 shares specifically to cover tax obligations. Those shares were sold at a price of $195.95, generating proceeds of $401,305.
Concurrent vesting and share acquisitions
The filings further show that on February 17 Mihm acquired 4,357 shares of Plexus common stock and 1,297 Performance Stock Units (PSUs). The newly acquired shares were the result of the vesting of those Performance Stock Units, as reported in the same disclosure.
Market context and company results
At the time the transactions were reported, Plexus shares were trading at $196.57. The stock has registered a 52.72% gain over the past six months and a 33.72% year-to-date return. A valuation platform referenced in the reporting currently indicates the stock is overvalued relative to its Fair Value estimate.
Separately, Plexus reported financial results for the first quarter of fiscal year 2026. Earnings per share were $1.78, above analysts’ expectations of $1.75, while revenue was reported at $1.07 billion, in line with forecasts. The company’s quarterly results were met with notable after-hours trading activity, reflecting market interest in the release.
What the filings show and what they do not
The Form 4 provides a clear record of the quantities, prices and dates of the insider transactions, plus the tax-related disposition and the shares issued on vesting. The filings do not provide additional commentary on the motivations behind the sales or acquisitions, and they do not quantify the proportion of the executive’s total holdings represented by these transactions.
Takeaway
The disclosure documents show a mix of sales, tax-related disposals and vesting-related acquisitions executed over two days in mid-February 2026, coinciding with the company’s release of its Q1 fiscal 2026 results. The stock’s recent strong price appreciation and a Fair Value indicator showing the share price as overvalued are also noted within the reporting.
