North America segment net sales, which includes all sales to customers in the U.S., Canada, and Mexico, increased $179.8 million, or 19%, to $1,135.4 million. Price/mix increased 24%, reflecting the carryover benefit of pricing actions taken in fiscal 2023 to counter inflationary pressures, as well as favorable mix, partially offset by lower customer transportation charges. Volume declined 5%, primarily reflecting our decisions to exit certain lower-priced and lower-margin business. To a lesser extent, lower shipments in response to inventory destocking by certain customers also pressured volumes.
International segment net sales, which includes all sales to customers outside of North America, increased $359.9 million, or 212%, to $529.9 million, and included $374.9 million of incremental sales attributable to the Acquisitions. International segment net sales, excluding the incremental sales attributable to the Acquisitions, declined 9%. Price/mix increased 18%, driven by the carryover benefit of pricing actions taken in fiscal 2023 to counter inflationary pressures, as well as favorable mix, partially offset by lower customer transportation charges. Volume declined 27%, primarily reflecting our decisions to exit certain lower-priced and lower-margin business. To a lesser extent, lower shipments in response to inventory destocking by certain customers in several markets in the Asia-Pacific region also pressured volume.
Gross Profit
Gross profit increased $226.2 million, or 83%, to $499.5 million, and included $22.5 million of costs ($16.7 million after-tax, or $0.11 per share) associated with the sale of inventory stepped-up to fair value in the LW EMEA Acquisition, and a $31.7 million ($23.8 million after-tax, or $0.16 per share) unrealized gain related to mark-to-market adjustments associated with commodity hedging contracts. The prior year quarter included a $4.0 million ($3.0 million after-tax, or $0.02 per share) unrealized loss related to mark-to-market adjustments associated with commodity hedging contracts. We have identified LW EMEA integration and acquisition-related items as items impacting comparability, and all unrealized mark-to-market gains and losses related to commodity derivatives as adjustments, in the current and prior year quarters.
Excluding unrealized mark-to-market commodity gains and losses and items impacting comparability, gross profit increased $213.0 million, driven primarily by: benefits from pricing actions, which more than offset the impact of higher costs on a per pound basis and lower sales volumes; the timing of trade spending in North America; and incremental earnings attributable to the consolidation of the financial results of LW EMEA. The higher costs per pound reflected mid-to-high-single-digit cost inflation for key inputs, including: raw potatoes, labor, ingredients such as grains and starches used in product coatings, and energy. The increase in per pound costs was partially offset by lower costs for edible oils and transportation.
Selling, General and Administrative Expenses
SG&A increased $59.9 million to $176.2 million in the first quarter of fiscal 2024, and included $4.0 million of LW EMEA integration and acquisition-related expenses ($3.0 million after-tax, or $0.02 per share), $4.4 million ($3.3 million after-tax, or $0.02 per share) of unrealized losses related to mark-to-market adjustments associated with currency hedging contracts, and $7.4 million ($5.5 million after-tax, or $0.04 per share) of foreign currency exchange losses. The prior year quarter included $1.0 million ($0.7 million after-tax, with no per share impact) of foreign currency exchange losses. Excluding these items, SG&A increased $45.1 million to $160.4 million, primarily due to incremental expenses attributable to the consolidation of the financial results of LW EMEA, and higher expenses related to improving our information systems and ERP infrastructure.
Segment Adjusted EBITDA
North America Segment Adjusted EBITDA increased $147.6 million to $379.4 million. The carryover benefit of pricing actions, the timing of trade spending, and favorable mix drove the increases, which were partially offset by higher costs per pound and the impact of lower volumes.
