Omnicom, one of the world's largest advertising groups, reports second-quarter earnings on July 21. The stock trades at barely over 8 times its free cash flow, a discount reflecting market fear that generative AI will replace part of agency work. My method nuances that story without dismissing it.

Key takeaways

• Omnicom reports Q2 2026 earnings on July 21 after market close.
• The stock trades at roughly 8.4 times its free cash flow, a discount tied to fears that generative AI will replace part of agencies' creative and media work.
• The real weak spot isn't profitability but margins: unlike most companies in my screener, Omnicom's margins aren't expanding, they're flat to slightly compressing.
• Accounting net margin looks very low (0.3%), but that's misleading: it includes one-off items from a recent acquisition, while the more reliable free cash flow margin reaches 14.5%.

What Omnicom does

Omnicom owns a portfolio of advertising, communications, and media-buying agencies (including BBDO, DDB, TBWA) that design campaigns and buy ad space on behalf of major global brands. It's a service business, heavily reliant on people rather than physical capital.

Why the market fears AI here

Generative AI can now produce visuals, ad copy, and even video scripts in minutes, tasks that used to occupy entire creative teams. The market fears that advertisers, especially smaller ones, will bypass agencies to produce this content in-house or directly through AI tools. That's a real risk to fees and volumes, not a fantasy.

But that story overlooks part of Omnicom's business: media budget management (where and when to run a campaign, for which audience, at what price), brand strategy, and coordinating global multi-market campaigns. Those are relational and strategic skills that generative AI alone doesn't yet replace.

What the numbers actually show

Omnicom's accounting net margin (0.3%) looks alarming, but it's distorted by one-off charges tied to a recent acquisition that weigh on reported earnings without reflecting the real profitability of the business. Free cash flow margin, harder to distort with one-off items, comes in at 14.5%, a decent level for a services business. Cash generation is also growing 25.8% a year on average over 5 years, a solid figure.

The real weak spot is operating margins: unlike most companies I consider quality, Omnicom's margins aren't structurally expanding over 5 years. In a skilled-labor business, that's a sign pricing power remains limited, consistent with the sector's competitive and technological pressure.

Valuation: is the market pricing in too much pessimism

At 8.4 times its free cash flow, Omnicom trades notably cheaper than the market average. That's the kind of discount typically found at a company the market judges structurally threatened. The question to settle before investing: does the AI risk justify a discount this wide, or is the market extrapolating a disruption that will actually take years to materialize, if it fully materializes at all?

What to watch on July 21

Beyond revenue, I'll watch client retention (are advertisers renewing contracts?) and any management commentary on internal AI use: a company that adopts AI to cut its own costs rather than suffer it can turn a threat into a margin improvement.

What I take away from this

Omnicom illustrates a case where fear of a technology can push a price down faster than the facts warrant, without that necessarily being a bargain either: the stagnant margins are a real signal, not a market invention. Separating sector fear (real, worth watching) from the strength of cash generated today (also real) is exactly the work my method tries to do before deciding.

About the author

Written by Lubin Danilo, founder of Lubin Investment. A self-taught individual investor, I find fundamental analysis fascinating, and it has delivered excellent results. For three years now, my performance has beaten the S&P 500. But analyzing every stock took too much time: sites with incomplete data, calculation methods and criteria never aligned with mine. And spotting the best stocks was just as time-consuming, even with my own well-defined checklist. So I put my software development background to work to build this software, base my investment strategy on its results, and share it with people who share the same passion as me. It judges a company's quality and its price separately, using criteria drawn from the financial literature (Warren Buffett, Michael Mauboussin, Aswath Damodaran).
