* As of 10/19/16. The net sales projections for fiscal year 2017 reflect the recent and significant deterioration of the British pound sterling. The

foreign currency exchange rate for the British pound sterling against the U.S. dollar has recently declined by approximately 15 percent from the

average exchange rates in fiscal year 2016. This guidance does not include any future acquisitions or divestitures and assumes that foreign

currency exchange rates and crude oil prices will remain close to current levels for fiscal year 2017. In addition, this guidance does not assume any

significant impact in other income from future balance sheet remeasurements as the Company experienced in fiscal year 2016.

management believes provide our stockholders with additional insights into WD-40 Company’s results of operations and how it runs its business. Our

of the Company from year to year or quarter to quarter. The non-GAAP measures referenced in this presentation, which include EBITDA (earnings before

interest, income taxes, depreciation and amortization) and the cost of doing business, are supplemental in nature and should not be considered in isolation

or as alternatives to net income, income from operations or other financial information prepared in accordance with GAAP as indicators of the Company’s
