April 30 (Reuters) - ArcelorMittal MT.AS, the world's second largest steelmaker, reported stronger-than-expected core earnings on Thursday, helped by higher steel prices and improved performance in its North America business.
The Luxembourg-based company posted first-quarter core earnings of $1.68 billion, beating analysts' average estimate of $1.65 billion, according to data compiled by LSEG.
