Thanks, Jeff, and good morning. Net sales were $4.7 million in Q1 2024, up 53% compared to the same period in 2023. The primary driver of the improvement was increased demand across all end markets as volumes were up $1.9 million or 63%. Partially offset by lower average selling price, which decreased sales $300,000 or 10%.
The increased sales included the $300,000 in trial material that Jeff mentioned earlier as well as approximately $600,000 of restocking by distributor, which worked off their inventory in 2023. The lower average selling price was primarily due to lower manufacturing costs, which were passed on to customers as well as product mix.
Gross profit was $1.1 million in the quarter, an increase of $520,000 from the same period last year. The improvement was primarily due to higher volumes, partially offset by the lower average selling price. Net of manufacturing depreciation, gross profit as a percentage of sales was 29.2% in the quarter compared to 32.6% in the same period in 2023.
The change was primarily due to lower average selling price due to product mix. SG&A expenses were $1.7 million during the quarter, an increase of $470,000 from the prior year period. The change was primarily due to $300,000 of asset relocation costs associated with internalization of our North American production to Burlington.
R&D expenses were $450,000 in the quarter compared to $600,000 in the same period in 2023. The decrease was primarily due to lower new product scale-up costs incurred during the current quarter. Adjusted EBITDA loss was $530,000 in the quarter compared to $590,000 in the same period in 2023. The improvement was primarily due to higher gross profit, offset by the higher operating costs in comparison to the prior year period.
Cash provided by operating activities was $1.1 million in the quarter compared to $290,000 in the prior period. This increase was primarily due to improved working capital. As of March 31, 2024, we had $33.7 million of cash in term deposits compared to $33.3 million as of year-end 2023. During Q1, we invested $600,000 in the NCIB to purchase and retire 166,000 shares. We have demonstrated our ability to responsibly manage our cash reserves through multiple cycles, while we continue to invest in our long-term growth strategy.
With that, I'll turn it back to Jeff for closing comments.
