The financial data reveals multiple trends over the analyzed quarters for key performance indicators including net sales, cost structure, profitability, and expenses.

Net Sales

Net sales exhibit a generally increasing trend with notable seasonal fluctuations, peaking in the fourth quarter of several years (e.g., August to November periods). The highest recorded net sales appear in late 2022 and 2023, indicating a strong revenue growth trajectory in recent periods.

Cost of Sales

The cost of sales, including warehouse and delivery expenses, follows a similar seasonal pattern to net sales, increasing in the same quarters and rising consistently over the years. Increases in cost of sales are roughly proportional to sales growth, suggesting stable gross margin management despite rising absolute costs.

Gross Profit

Gross profit mirrors net sales with consistent growth and periodic peak increases in end-of-year quarters. The gross profit margins appear to remain stable or improve slightly, evidenced by growing gross profit levels outpacing costs during peak sales periods, indicating effective cost control and revenue generation capabilities.

Operating, Selling, General and Administrative Expenses

Operating expenses demonstrate an increasing trend but with less volatility compared to sales and cost of sales. Periodic spikes correspond to quarters with the highest sales volume, reflecting higher marketing or administrative activity aligned with revenue cycles. Expenses tend to increase steadily across the full timeline, suggesting expanding operational scale or rising costs.

Operating Profit

Operating profit shows substantial growth over the periods, with pronounced peaks matching quarters of high sales and gross profit. Although some quarters exhibit dips, the overall upward trajectory indicates improving operational efficiency and profitability management over time.

Interest Expense, Net

Net interest expense remains relatively stable but shows a modest upward trend, particularly increasing in the latest quarters. This suggests growing debt or cost of financing, which may impact net profitability if the trend continues.

Income Before Income Taxes

Income before taxes rises generally in line with operating profit, reaching new highs in the most recent periods. This indicates that non-operating items have a minor impact relative to core operations, and the company’s profitability before tax continues to strengthen.

Income Tax Expense

Income tax expenses fluctuate, occasionally registering negative amounts, which may denote tax benefits or accounting adjustments in certain quarters. Overall, tax expense tends to increase alongside income before tax, but variability suggests changes in effective tax rates or tax planning strategies over time.

Net Income

Net income reflects a strong growth pattern consistent with operating profit and income before taxes. Periodic increases are evident in quarters with higher sales and operational performance. Recent quarters show notable profits reaching new peaks, indicating effective translation of revenues into bottom-line earnings despite increasing costs and interest expenses.
