Operating income growth hasn't been enough to stop big sell-offs

Mesa Labs recorded a loss of $0.75 per share on sales of $63.72 million in fiscal Q4. Performance in the period saw revenue fall roughly $1.48 million short of the average Wall Street analyst target. On the other hand, the company did see strong growth for adjusted operating income.

Mesa posted adjusted operating income per share of $3.30 last quarter, beating the average Wall Street analyst estimate by $1.76. Performance in the quarter marked a significant improvement over the company's adjusted operating income per share of $2.25 in the prior-year period.

What's next for Mesa Labs?

Mesa president and CEO Siddhartha Kadia is still conducting an internal review of the business and expects to be able to deliver full-year guidance with the company's fiscal Q2 report. The company says that it has seen some loosening in export controls for Peptide systems over the last month, and management sees further room for improvement when it comes to supporting growth in the product category.
