Question #1

Given the stark contrast between the successful Onto merger and the “major disaster” of a smaller technical acquisition, does Plisinski possess the detailed, hands-on discipline required to successfully integrate Semilab, or is his M&A strength primarily in high-level strategic combination?

Question #2

When faced with aggressive competition from KLA that erodes core market share, is Plisinski’s instinct to engage in a direct, commercially-focused fight, or to pivot the company’s focus towards adjacent, less contested growth opportunities?

Question #3

Does Plisinski’s strategic optimism in high-growth markets like AI lead him to set aggressive public forecasts that strain operational reality and credibility, or does he possess the internal discipline to ensure his bold predictions are consistently delivered?
