Retail segment net sales increased $85.9 million, or 31%, to $361.0 million. Price/mix increased 38%, while volume decreased 7%. The carryover benefits of product and freight pricing actions across the branded and private label portfolios taken in the prior year, as well as actions taken in fiscal 2023 to counter inflation, largely drove the increase in price/mix. While consumer demand for frozen potato products remained strong, the decline in the segment’s overall volume was due largely to the impact of supply chain disruptions on run-rates and throughput in our production facilities for branded products, as well as incremental losses of certain low-margin, private label business.
Other segment net sales increased $1.8 million, or 3%, to $64.3 million. Price/mix increased 8% and was driven by higher prices in our vegetable business. Volume decreased 5%, reflecting the negative effect of the extreme summer heat on the yield and quality of the vegetable crops.
Gross Profit and Product Contribution Margin
Gross profit increased $298.1 million, or 84%, to $654.9 million, as benefits from pricing actions more than offset the impact of higher manufacturing and distribution costs on a per-pound basis, as well as lower sales volumes. The higher costs per pound predominantly reflected double-digit cost inflation from key inputs, including: edible oils; ingredients, such as grains and starches used in product coatings; transportation; and labor. The increase in costs per pound also reflected higher costs associated with the impact of extreme summer heat that negatively affected the yield and quality of potato crops in the Pacific Northwest in fall 2021, as well as the effects of supply chain disruptions on run-rates and throughput in our production facilities. The increase in per pound costs was partially offset by supply chain productivity savings.
Our overall product contribution margin increased $296.1 million, or 85%, to $643.8 million. The increase was largely due to higher sales and gross profit (as described above).
Global segment product contribution margin increased $131.2 million, or 106%, to $254.7 million. Pricing actions drove the increase, more than offsetting higher manufacturing and distribution costs per pound, as well as unfavorable mix. Global segment cost of sales was $995.6 million, up 12% compared to the first half of fiscal 2022, primarily due to higher manufacturing and distribution costs.
Foodservice segment product contribution margin increased $68.3 million, or 34%, to $269.1 million. Pricing actions drove the increase, and was partially offset by higher manufacturing and distribution costs per pound, unfavorable mix, and the impact of lower sales volumes. Foodservice segment cost of sales was $452.3 million, up 5% compared to the first half of fiscal 2022, due to higher manufacturing and distribution costs, partially offset by lower sales volumes.
Retail segment product contribution margin increased $78.2 million, or 216%, to $114.4 million. Pricing actions drove the increase, partially offset by higher manufacturing and distribution costs per pound. Retail segment cost of sales was $240.9 million, up 3% compared to the first half of fiscal 2022, primarily due to higher manufacturing and distribution costs, partially offset by lower sales volumes.
Other segment product contribution margin increased $18.4 million to $5.6 million in the first half of fiscal 2023, as compared to a loss of $12.8 million in the first half of fiscal 2022. These amounts include a $6.9 million loss related to unrealized mark-to-market adjustments and realized settlements associated with commodity hedging contracts, and a $16.9 million loss related to the contracts in fiscal 2022. Excluding these mark-to-market adjustments and realized settlements, Other segment product contribution margin increased $8.4 million, largely due to pricing actions in our vegetable business.
Selling, General and Administrative Expenses
SG&A increased $43.9 million to $226.1 million in the first half of fiscal 2023, and includes a net $26.5 million gain ($19.2 million after-tax, or $0.13 per share) related to actions taken to mitigate the effect of changes in currency rates on the pending purchase of the remaining ownership interest in LWM, net of other acquisition-related costs. Excluding items impacting comparability, SG&A increased $70.4 million to $252.6 million, primarily due to higher compensation and benefits expense, and higher expenses related to improving our information systems and ERP infrastructure.
