“Our second quarter guidance includes a seasonal sequential sales lift, although muted from prior expectations given timing shifts from the second quarter into the first quarter in Semiconductor Technologies.” “Our full year 2025 guidance remains unchanged from our prior outlook. Further, full year guidance does not include a net cost impact of announced tariffs currently estimated at $60 million, or about $0.10 per share,” Franzen concluded. 3 Conference Call The Company will host a live webcast of its quarterly earnings conference call with investors to discuss its results and business outlook beginning today at 8:00 a.m. ET.
