The mobile fold reads cleanly: the headline "Changing the world, one nanometer at a time" scales down to a comfortable four lines, the subhead is legible at arm's length, and the nav collapses to a tidy hamburger plus search icon that stays out of the hero's way. The problem is action: there is no primary CTA anywhere in the first mobile viewport — the entire fold is headline, subhead, and background photo, so a visitor has nothing to tap until scrolling past a full screen of hero image to reach the "Quick Links" list. Those quick links ("About ASML", "Careers", "Products", "Financial results") are themselves text-link rows rather than a thumb-friendly full-width button, and the hero image occupies a long dead stretch between the subhead and the first tappable element. The biggest lever is placing one full-width action — even a "Explore products" button — directly under the subhead inside the first viewport.
