Energizer Holdings' stock surged 8.58% in pre-market trading on Tuesday, following the release of its fiscal second-quarter results.

The significant price movement was driven by the company reporting adjusted earnings per share of $0.94, which substantially exceeded analyst estimates of $0.46. Despite a 3% decline in net sales to $643.3 million, Energizer demonstrated strong profitability improvement, with its gross margin expanding to 40.2%. This performance was bolstered by a $47.6 million tariff refund and $11.7 million in production tax credits.

Furthermore, the company raised its full-year guidance, now expecting adjusted earnings per share to reach the high end of its previously provided range of $3.30 to $3.60. Management expressed growing confidence in a return to organic sales growth in the latter half of the fiscal year, which contributed to positive investor sentiment during the pre-market session.
