Both GAAP and core sales declined 7% sequentially. o Display Technologies’ sales declined 3% sequentially as both volume and glass price declined slightly. Volume increased significantly in March as conditions in China improved and panel maker utilization resumed its recovery. o Optical Communications’ sales decreased 6% sequentially as pricing actions partially offset a greater-than-normal seasonal volume decline associated with the pacing of customer projects. o Environmental Technologies’ sales increased 9% sequentially. Increased gasoline particulate filter adoption helped drive the sequential improvement. ● First-quarter GAAP EPS was $0.20. Core EPS was $0.41 versus $0.47 for the prior quarter.","evidence_source":"SEC 8-K Item 2.02","evidence_url":"https://www.sec.gov/Archives/edgar/data/24741/000143774923010959/0001437749-23-010959-index.htm","confidence":1.0,"family_label":"Earnings Releases","details":[{"label":"Period","value":"first quarter ended March 31, 2023"},{"label":"Revenue","value":"$3.2 billion and $3.4 billion"},{"label":"EPS","value":"$0.20 and $0.41"},{"label":"Guidance","value":"initiated"},{"label":"Result","value":"reported results"}],"fact_type":"earnings_release"}],"license":"Source filings: public domain (SEC EDGAR).
