Why OSI Systems Seems Radioactive Today
OSI Systems (OSIS) stock fell 9.9% after reporting Q4 earnings that missed revenue expectations, with sales declining 4% year over year. The company reported $3.78 per share in non-GAAP profit, beating estimates, but GAAP earnings grew only 8%. Full-year sales grew 4% to $1.8 billion, with GAAP earnings up 3% to $8.95 per share. Management forecasts accelerated growth for 2027, with sales expected to rise up to 8% and non-GAAP earnings up to 11%.
