An analyst performing vertical analysis notes a decline in gross profit margin. Which scenario would explain this?

• A. The firm has reduced its prices relative to the cost of merchandise sold
• B. Increased advertising expense
• C. Higher depreciation expense
• D. Lower tax rate

Answer: (A)

Gross profit margin shows how much of each sales dollar remains after covering the cost of goods sold. If selling prices fall while the cost to acquire or produce the goods stays the same, gross profit per unit drops, pulling the overall gross profit margin down. In other words, net sales shrink or stay flat while COGS doesn’t drop in tandem, so the margin declines. Advertising expense, depreciation, and taxes affect other levels of profitability but not the gross profit margin directly. Advertising is an operating expense after gross profit, depreciation typically falls outside COGS unless specifically tied to production, and tax changes occur after profit is calculated, so they don’t explain a drop in gross margin.
