Top Communication Services Stocks by Gross Margin

How this ranking is built

Companies are ranked by gross margin as reported in their most recent annual filing with the SEC. Figures shown are in US dollars (or percent, as noted), rounded to two decimals.

• Source: annual 10-K / 20-F filings from companies trading on US exchanges (NYSE, Nasdaq, AMEX).
• Fiscal year: whichever annual period the company has most recently filed. Fiscal years don't always align with the calendar year, so the "as of FY" stamp above reflects the most common year across the table.
• Filtered out: warrants, preferred shares, and duplicate listings that share a parent company's financials.
• Size floor: A company qualifies at $1 billion in annual revenue or above, so a small filer with a freak ratio cannot top the list.
• Value range: Only figures above 0% and up to 100% qualify.
• Narrow cost lines: A company whose cost line holds only part of its direct costs, such as a utility counting only the energy it buys, is left out, because revenue less that line is not a gross margin. Its financials page shows the figure under its own name.
• Cost-classification check: A company whose gross margin runs more than 70 points above its operating margin is left out, because at that gap the split between cost of sales and operating cost is a reporting convention rather than a margin. A company with no usable operating margin, usually because it reports no operating income, is left out too, since the gap cannot be checked.
• Market cap: stated at each company's latest close, which is newer than the annual figure ranked here.
• Update cadence: refreshed as companies file new annual reports (typically within 60–90 days of fiscal year end).
