(1) During the nine months ended September 30, 2023, the Company updated its methodology for determining the country of origin for its sales. Sales are now recorded by shipping country rather than billing country. The Company updated the methodology retrospectively, adjusting the prior year presentation for all regions presented.

(2) The line item presented above previously bifurcated sales between the United States and Canada. Due to the updated methodology for determining the country of origin for sales, it was noted that Canada no longer was a material location to separately disclose. Both have been combined in the line item presented above to more accurately reflect origin of sales for material regions.
