Bausch + Lomb Corp. (BLCO) shares tumbled 6.34% in pre-market trading on Wednesday following the release of its disappointing first-quarter earnings report. The eye health company's results fell short of analyst expectations, prompting a sell-off among investors.

The company reported a quarterly loss of $0.07 per share, a stark contrast to the $0.03 per share profit analysts had forecast. This represents a significant downturn from the same period last year when Bausch + Lomb posted earnings of $0.07 per share. The dramatic 333.33% miss on earnings expectations likely contributed to the sharp decline in the stock's pre-market price.

While Bausch + Lomb's sales showed some growth, increasing 3.46% year-over-year to $1.14 billion, they still fell short of the $1.15 billion analyst consensus estimate. The slight miss on revenue, combined with the unexpected loss, paints a challenging picture for the company's current financial position and near-term outlook, which appears to have shaken investor confidence in the pre-market session.
