If a company reports a high gross margin but a low net margin, which is the most likely explanation?

• A. High operating expenses relative to revenue.
• B. Low COGS
• C. Large one-time gains
• D. High depreciation

Answer: (A)

When gross margin is high but net margin is low, it means production efficiency is solid (COGS relative to revenue is favorable), but other costs are dragging profitability down. Net margin accounts for all expenses beyond COGS—operating expenses like selling, general and administrative costs, and other overhead, plus interest, taxes, and non-cash items like depreciation. If these ongoing costs are large relative to revenue, they erode net income even though the company is good at producing its goods. To see this in numbers: if revenue is 100 and COGS is 40, gross margin is 60. If operating expenses total 50, net income is 10, giving a net margin of 10%. The pattern described is best explained by high operating expenses relative to revenue. Lower COGS would raise gross margin (not the issue here), large one-time gains would boost net margin (opposite effect), and while high depreciation can reduce net margin, it’s a specific part of operating costs rather than the overarching cause of a persistently high gross but low net margin.
