Oshkosh Corporation (NYSE: OSK) saw its shares tumble 5.29% in pre-market trading on Wednesday, following the release of its third-quarter financial results. The company reported mixed performance, with earnings surpassing expectations but sales falling short of estimates.

For the third quarter, Oshkosh posted adjusted earnings per share of $3.20, beating the analyst consensus estimate of $3.07 by 4.13%. This represents a 9.22% increase from the $2.93 per share reported in the same period last year. However, the company's quarterly sales of $2.686 billion missed the analyst consensus estimate of $2.836 billion by 5.29%. More concerning for investors, this figure represents a 2.01% decrease compared to sales of $2.741 billion in the same quarter of the previous year.

Despite the earnings beat, the significant miss on sales and the year-over-year revenue decline appear to be the primary drivers behind the stock's pre-market plunge. Oshkosh also provided its full-year outlook, projecting adjusted EPS of $10.50 to $11.00 and sales between $10.3 billion and $10.4 billion. Investors will likely be closely watching how the company plans to address the sales shortfall and return to growth in the coming quarters.
