Reading Q3 Ad Earnings Season Signals for UA Buyers

Meta and Alphabet are both due to report earnings this week, with AppLovin and Unity following in early November, and most UA teams will read the resulting headlines, note the revenue growth number, and move on. That is a thinner read than Q3 ad earnings season signals deserve. A UA buyer does not hold the stock and does not need the quarter's net income to do their job. What a buyer needs from earnings season is the demand and investment signal buried underneath the headline number, and that signal is available whether or not the reported quarter beats expectations.

Why earnings season matters to someone who isn't an investor

An ad platform's earnings call is one of the only moments in a quarter when the company is legally required to say something specific and forward-looking about demand, in a format analysts will hold it to. Executives cannot say "advertiser demand is soft" in an earnings call and then contradict it in a sales conversation the following week without consequence, which makes the language on these calls more reliable than most of what a buyer hears from an account manager. Q3 ad earnings season signals are useful precisely because they are the most disciplined, most audited statements these companies make about the direction of their own advertising business all quarter.

What to actually listen for

The topline revenue growth number is the least useful part of the call for a buyer's purposes, because it is backward-looking and already mostly priced into market expectations before the call happens. More useful:

• Guidance language for the following quarter, particularly any specific reference to Q4 demand, holiday seasonality, or CPM expectations, since that is the platform's own read on the market a buyer is about to spend into.
• Capital expenditure and AI infrastructure commentary, because platforms have spent much of 2025 explaining ad performance gains through AI-driven automation, and the scale of continued investment is a rough proxy for how much further automated bidding and creative tools are likely to improve within the quarter.
• Any direct mention of gaming as a vertical, since gaming advertiser demand does not always move in the same direction as overall ad demand and a platform calling it out specifically, positively or negatively, is a more targeted signal than the blended number.
• Management's tone on advertiser concentration or diversification, since a platform leaning harder into automated, self-serve tooling for smaller advertisers tends to signal a different competitive environment for UA budgets than one still built around a small number of large managed accounts.

What this looked like last quarter

The value of this framework is easiest to see against a quarter that already happened. When AppLovin and Unity both reported Q2 results on the same day in August, the headline comparison was stark: AppLovin's advertising revenue up 77% year on year against Unity's overall revenue down 2%, though Unity's decline still beat its own guidance and its ad network grew sequentially. As UA Ledger covered in AppLovin Unity Q2 2025 Earnings: Two Diverging Paths, the useful signal was not the growth-rate gap itself but what each company said was driving it: AppLovin's AXON engine scaling further into e-commerce advertisers beyond gaming, and Unity's Vector rebuild finally showing sequential ad network growth after a difficult year. A buyer reading past the headline number in August had a genuine reason to revisit budget allocation toward Unity's ad network earlier than the blended revenue comparison alone would have justified.

Q3 ad earnings season signals: a listening checklist

A buyer with limited time to actually sit through four earnings calls across two weeks can get most of the value from a shorter checklist run against the transcript or a summary afterward:

• Note the specific words used for Q4 guidance, strong, cautious, mixed, rather than just the percentage growth figure, since platforms choose that language carefully and a shift in tone from the prior quarter's call is often more informative than the number itself.
• Note whether gaming gets a standalone mention or is folded into a broader "apps" or "mobile" category, since a standalone mention usually signals the vertical is either unusually strong or unusually weak relative to the platform's other advertiser categories that quarter.
• Note any change in how management describes advertiser count or advertiser concentration, since a platform emphasising growth in small and mid-size advertisers is signalling a different opportunity for a mid-size UA team than one emphasising a small number of very large accounts.
• Note whether capex guidance for the following year moved up, down or stayed flat against the prior quarter's commentary, since that is the closest thing to a forward read on how much further automated tooling is likely to improve within a buyer's planning horizon.

Reading this week without pretending to know the outcome

Neither Meta's nor Alphabet's Q3 results are in yet as this goes to publication, and nothing here should be read as a forecast of what either company will report. What is worth setting up in advance is the listening framework above, applied the moment the calls happen: watch for how each company frames Q4 guidance for advertisers generally, watch for any specific gaming vertical commentary given how much of Meta's Advantage+ adoption story this year has leaned on gaming as a strong-performing category, and watch for capex commentary that signals whether the AI-driven automation both companies have been selling advertisers all year is accelerating or levelling off heading into the busiest quarter of the year.

What comes next

AppLovin and Unity follow in early November, close enough behind Meta and Alphabet that a buyer will have two full earnings weeks to build a reasonably complete picture of ad platform demand heading into the holiday period, before most Q4 budgets are fully locked. The teams that get the most out of Q3 ad earnings season signals are not the ones who read the headlines fastest. They are the ones who already know which three or four things on each call actually change a media plan, and who treat the intervening two weeks between Meta's results and Unity's as a single earnings season to read together rather than four unrelated news events.
