Updated 2026-10-28 · 15 stocks · Scores are Marvin's own

Communication Services covers businesses that connect people or deliver media and messages. Examples include phone networks, streaming, publishing, advertising and online platforms. This list picks out the 15 companies in that sector that are profitable and grew revenue the fastest in their last fiscal year.

Fast growth is only part of the story. A company can grow quickly and still keep little of each dollar as profit, or take on a lot of debt to fund that growth. So each pick below also shows margins and, where available, a debt figure.

Marvin's scores run from 0 to 100 and compare a company with others in its own industry, not with the whole market. They describe where a company stands today and are not predictions. Some figures are missing for certain stocks, and each blurb notes this where it matters.

The stocks, one by one

Reddit, Inc. RDDT

Communication Services · Internet Content & Information
Overall 84 Business 89 Opportunity 88

Reddit tops the list with revenue growth of 69.4% last fiscal year, plus an operating margin of 28.2% and a free cash flow margin of 36.7%. That suggests rapid growth that is also turning into real profit. Caution: no debt-to-equity figure is available, so its borrowing can't be judged here.

Array Digital Infrastructure Inc AD

Communication Services · Telecommunications Services
Overall 61 Business 65 Opportunity 49

Array Digital Infrastructure grew revenue 58.3% and shows an operating margin of 241.3%, an unusually high figure. Its free cash flow margin is -158.3%, meaning cash went out rather than in. Caution: profit and cash don't line up, and its Overall score of 61 is among the lower ones here.

EverQuote, Inc. EVER

Communication Services · Internet Content & Information
Overall 86 Business 79 Opportunity 94

EverQuote grew revenue 38.5% and keeps a very high gross margin of 97.6%. Its Overall score is 86. Caution: the operating margin of 11.0% is much smaller than the gross margin, so other costs take a big share, and no debt figure is available.

MediaAlpha, Inc. MAX

Communication Services · Internet Content & Information
Overall 76 Business 67 Opportunity 91

MediaAlpha grew revenue 28.8%, but margins are thin: 6.9% operating and just 14.7% gross. Its return on equity of 342.2% looks striking, yet a debt-to-equity ratio of 6.22 means heavy borrowing may be inflating it. Caution: little profit is kept from each sale.

DoorDash, Inc. DASH

Communication Services · Internet Content & Information
Overall 71 Business 77 Opportunity 28

DoorDash grew revenue 27.9% and turned 16.3% of revenue into free cash flow, a decent cash showing. Caution: the operating margin is only 4.5%, its Opportunity score is a low 28, and gross margin and debt figures are not available.

Formula One Group grew revenue 22.7% with a free cash flow margin of 19.0% and a modest debt-to-equity ratio of 0.65. Its Quality score is 89. Caution: return on equity is only 5.4%, and the Opportunity score of 40 is middling.

Entravision Communications EVC

Communication Services · Broadcasting
Overall 82 Business 72 Opportunity 78

Entravision Communications grew revenue 22.6%, with an Overall score of 82. Caution: the operating margin is only 3.1%, return on equity is 5.0%, and the debt-to-equity ratio of 2.47 shows more borrowing than most names on this list.

Common questions

Does fast revenue growth make a company a better stock?

Not by itself. Revenue growth shows how quickly sales rose in the last fiscal year, but not whether the company keeps much of that money as profit or how much debt it took on. That is why this list also shows margins and, where available, debt.

What is operating margin and why does it matter here?

Operating margin is the share of revenue left after the costs of running the business, before interest and taxes. A higher figure means more of each sale is kept as operating profit. Several fast growers here have thin operating margins, so growth has not yet turned into much profit.

Why do some stocks have no debt or gross margin figure?

Marvin only shows a figure when the data is available for that company. Some companies do not report a gross margin in a comparable way, and debt-to-equity can be missing. Where a figure is absent, treat that part of the picture as unknown rather than good or bad.
