Heico Corporation (HEI) experienced a significant stock plummet of 6.72% in Wednesday's pre-market trading session, following the release of its disappointing fiscal fourth-quarter results.

The aerospace and defense company reported quarterly sales of $1.01 billion, falling short of analysts' estimates of $1.03 billion. This sales miss raised concerns among investors about Heico's growth prospects and its ability to navigate the challenging economic environment.

Heico cited slowing demand and economic headwinds as factors weighing down its sales growth, particularly in the aerospace sector. The company's Electronic Technologies Group segment witnessed a 2% year-over-year decline in sales due to lower defense and "other" electronics sales, further exacerbating the impact on overall revenue.
