Americas segment sales in the third quarter were $47.6 million, up 8% compared to the third quarter last fiscal year and were $133.3 million year-to-date,  up 2% compared to the prior fiscal year period. Europe segment sales in the third quarter were $32.5 million, up 8% and were $100.1 million year-to-date, up 13%  compared to the same periods last fiscal year. Asia-Pacific segment sales remained constant at $13.0 million in the third quarter and were $41.7 million year-to-date, up 7% compared to the same period last fiscal year.

Diluted earnings per share were $0.66 in the third quarter, compared to $0.57 per share for the same quarter of the prior fiscal year. Year-to-date diluted earnings per share were $2.01 compared to $1.64 in the same period last fiscal year.

"We are pleased with our performance across the globe this past fiscal year, and have confidence in our ability to continue to leverage the WD-40 shield and to create solid growth in our core product lines,” said Garry Ridge, WD-40 Company president and chief executive officer. “As we continue to celebrate our 60th anniversary as a company, we are thinking big about our future as we strive to maintain growth in our multi-purpose maintenance products lines and implement our strategic initiatives.”

Net sales by segment as a percent of total net sales were as follows: for the Americas, 51% for the third quarter and 49% year-to-date; for Europe, 35% for the third quarter and 36% year-to-date; and, for Asia-Pacific, 14% for the third quarter and 15% year-to-date.

“Our performance in Europe is in line with our expectations and we are seeing the rebound we have been expecting as we keep our focus on long-term growth,” Ridge said.  “We also continue to see long-term opportunities throughout Asia, particularly in China, but there will always be a lot of ups and downs due to the timing of promotional programs, shifting economic growth patterns and varying industrial activities in China. Despite a slight decline in sales in China so far this year, we continue to make more people aware of our products and make them easier to buy, each and every day.”

Gross margin was 51.3% in the third quarter compared to 49.5% in the same quarter last fiscal year. Year-to-date, gross margin was 50.8%, compared to 49.1% in the same period last fiscal year.

“We have been working to get our gross margin above fifty percent and are pleased with our progress," Ridge said. "During the quarter we saw improvements in gross margin from price increases, lower promotional allowances, changes we have made in our supply chain and foreign currency exchange rates, offset by higher input costs and our mix of sales."

Selling, general and administrative expenses were up 13% in the third quarter to $25.7 million and were up 11% year-to-date to $74.9 million as compared to the same periods last fiscal year.

Advertising and sales promotion expenses were down 1% in the third quarter to $6.6 million compared to the same period last fiscal year and were down 8% year-to-date to $18.0 million compared to the same period last fiscal year.

The WD-40 Specialist® product line was launched in fiscal year 2012 and was expanded into additional countries in the first half of fiscal year 2013. During the second quarter of fiscal year 2013, the company launched three additional products in the WD-40 Specialist line. The company also recently launched the WD-40 Specialist Motor Bike line in the U.K. as well. 

“We are pleased with the overall performance of the WD-40 Brand and how the WD-40 Specialist line and the power of the shield have helped us grow our business in the multi-purpose maintenance category,” Ridge said. “We know it is working as an overall strategy due to the growth we have been able to generate for these new products and the growth of the WD-40 Multi-use Product at the same time."

As we continue our innovation efforts we expect to see success from the products we already have in the marketplace, products we plan to launch within the next year and our long-term opportunities for new product and category introductions," Ridge added.
