Shares of WD-40 Company (WDFC) surged 5.49% in pre-market trading on Tuesday following the release of its impressive second-quarter fiscal 2025 financial results and an upward revision of its full-year earnings guidance.

The San Diego-based maker of the iconic lubricant spray reported a significant jump in quarterly earnings, with net income reaching $29.9 million, or $2.19 per diluted share, compared to $15.5 million, or $1.14 per share, in the same period last year. Adjusted earnings per share came in at $1.32, surpassing analysts' expectations of $1.27.

WD-40's strong performance was driven by robust sales growth, particularly in its core maintenance products. Total net sales for the quarter increased by 5% to $146.1 million, with the Americas segment growing by 3% and the Europe, India, Middle East, and Africa (EIMEA) segment posting an impressive 10% gain. The company also reported a notable improvement in gross margin, which expanded by 220 basis points to 54.6% compared to the prior year quarter.

In light of these strong results, WD-40 raised its full-year earnings outlook. The company now expects diluted earnings per share for fiscal year 2025 to be between $5.25 and $5.55, up from the previous guidance of $5.20 to $5.45. This upward revision, coupled with the better-than-expected quarterly performance, appears to be fueling investor optimism and driving the stock's pre-market rally.
