The AI frenzy has investors fixated on revenue growth as proof of returns on AI spending that can be as high as $100 billion per year, depending on the company. Yet, Meta is proving that a stronger signal of AI strength may be found further down the income statement — in the bottom line.
Without much fanfare, Meta put up a solid earnings report this past quarter as ad impressions rebounded to 11% up from 5% growth; this is a critical metric for the company as management must prove they are reaping the rewards of large capex spending. However, it’s also clear the large capex spend is impacting the bottom line as the company beat by 22% for growth of 38.4%. When adding back the $0.52 tailwind from increasing the useful life of servers, EPS beat by 11.2%.
There is evidence that both the top line and bottom line can continue to improve as Meta quietly asserts its AI strength come 2026. This quarter, average revenue per person (ARPP) is showing initial signs of bottoming with an important uptick YoY that was absent last quarter when ARPP declined YoY. Secondly, Meta has indicated their internal AI operations will result in lower headcount come 2026 as AI reaches the capabilities of a mid-level software engineer. Combined with a potential inflection point in their ad business, that indicates strong double digit EPS growth will continue in 2026.
Accelerating Growth in Core Business – Largest Beat in Nearly 4 years
Revenue for the quarter came in at $47.5 billion, beating consensus by $3 billion. While a 5% top-line beat may seem modest at first glance, this was Meta’s largest revenue surprise in 15 quarters. When removing one-time adjustments, EPS beat by 11%, or nearly double the beat seen on the top line.
Meta’s year-over-year revenue growth shows acceleration from 16% in Q1 FY25 to 21.6% in Q2 FY25, with projections for continued growth above 20% into Q3 FY25.
This quarter’s performance stands in sharp contrast to Q1, when revenue grew a modest 16% YoY, with just a $1 billion beat, and ad impressions were up a muted 5%. In other words, Q2 wasn’t just another incremental improvement, it was a potential inflection point that reset expectations for the back half of the year. It may have also signaled that Meta’s core advertising engine could renew its upward trajectory from the impact of its AI investments.
Looking ahead, Q3 guidance calls for revenue between $47.5 billion and $50.5 billion, implying another quarter of ~21% YoY growth at the midpoint. If the Company can continue to deliver back-to-back quarters of >20% growth, this should put the narrative of slowing growth in the rearview.
Sequential Improvement in Margins, up 5 points YoY
Revenue grew 16% YoY, the slowest rate since Q2 2023 as Meta lapped tough comps. Ad impressions growth decelerated to 5%, with all regions slowing sharply.
Meta’s operating margin expanded five points year-over-year, rising from 38% in Q2 FY24 to 43% in Q2 FY25, highlighting stronger profitability trends.
Ad impressions rebounded to 11% YoY, more than doubling sequentially. APAC led the way with +16% impressions growth, while US & Canada improved significantly, climbing to +9% from just +4% in Q1. Ad pricing remained firm at 9% YoY, a slight deceleration from Q1 but notable given the acceleration in impressions.
AI at the Core of Ad Re-Acceleration
The key driver behind this resurgence is Meta’s aggressive deployment of AI to improve ad efficiency and user engagement. Management highlighted recent upgrades to its ad recommendation system, which now leverages more signals and longer context windows to drive higher performance.
These improvements had tangible effects in Q2. Ad conversions increased ~5% on Instagram and ~3% on Facebook, reflecting the system’s ability to better match advertisers with the right audiences. Time spent also improved meaningfully, rising 5% on Facebook and 6% on Instagram, which expands available inventory.
Meta Q2 2025 Ad Impressions Surge: Significant Quarter-over-Quarter Growth Highlights Strong Performance
This dynamic showed up clearly in Meta’s performance metrics. The rebound in ad impressions from +5% in Q1 to +11% in Q2 was the sharpest sequential improvement over a year, driven by strength across regions, particularly in APAC. Despite this surge in volume, pricing held firm, increasing 9% YoY, just a modest deceleration from the prior quarter’s 10% growth. This stability indicates advertisers are seeing higher value per impression, thanks in large part to AI-driven performance gains.
ARPP also benefitted from these trends, climbing nearly $2 year over year to $13.65, just shy of Q4’s record $14.25. This suggests advertisers aren’t just buying more impressions, they’re paying more for better-performing ones.
At the center of this success is Advantage+, Meta’s flagship AI ad platform. Advantage+ automates campaign targeting, budget allocation, and creative generation, providing advertisers with a powerful easy-to-use tool that integrates generative AI directly into Meta’s ad ecosystem. The results speak for themselves: Advantage+ is now operating at a $20 billion annual run rate, up 70% YoY.
Advertisers using Advantage+ report up to 22% improvements in returns on ad spend (ROAS), and adoption continues to climb, with more than 4 million advertisers now using at least one generative AI creative tool.
According to the most recent earnings call, management stated why they are seeing such rapid growth: "studies show that for every dollar spent with our AI-enabled Advantage+ products, advertisers generate on average $4.52 in revenue for their businesses.”

Overall, Meta theoretically has a quick time to market for AI improvements to make an immediate impact on its existing monetization engine; the ad platform. This difference makes Meta’s capex cycle less speculative in the immediate term. While many peers front-loaded their AI spending over the past 12-18 months without a clear timeline for payback, Meta is scaling infrastructure after achieving product-market fit, with clear visibility into ROI.
Meta also has an unrivaled distribution advantage. Roughly 700 million monthly users already engage with embedded Meta AI features inside Facebook, Instagram, and WhatsApp. More recently, the company announced they reached 1 billion users across their AI services following the launch of the Meta AI app last April
With 3.4 billion total daily active people across its Family of Apps, Meta can distribute new AI features at scale. Unlike standalone AI apps that must drive user acquisition, Meta can compress the adoption curve dramatically by deploying AI directly into platforms where billions of people already spend time.
Building the Infrastructure to Match
Mark Zuckerberg confirmed that the Company is building Prometheus, which will be the first 1+ GW AI Accelerator cluster, slated to come online in 2026. Capex is ramping rapidly to meet these goals. For FY25, guidance now calls for $66-72 billion, up from roughly $40 billion in 2024.

Management also provided visibility into $100 billion in annual capex by 2026, reflecting Meta’s commitment to building out training and inference capacity at unprecedented scale. Unlike earlier cycles, where spending was tied to long-lived assets or speculative projects like the metaverse, this wave of investment is highly focused on shorter-lived assets such as GPUs, networking gear, and data center hardware that directly power ads, inference and generative AI workloads.
Funding From Strength, Not Dilution
One of Meta’s biggest advantages is its ability to self-fund this ambitious AI buildout. The company generated $25.6B in operating cash flow during Q2, representing a robust 53.8% margin. Free Cash Flow came in at $8.6B, down from $10.3B in Q1 as capex surged, but still massive relative to nearly any other company in tech.
Cash balance declined to $47.1B, reflecting the Company’s $15 billion Scale AI acquisition, while debt remained steady at $28.8B. Management emphasized that it plans to finance the bulk of its capex internally, while also exploring co-development partnerships for certain mega-projects. This flexibility distinguishes Meta from smaller AI infrastructure players that rely heavily on capital markets to fund growth.
Margins Stable Today, but 2026 a Watch Item
Despite the surge in spending, Meta’s margins held strong in Q2. Gross margin held steady at 82.1%, up 80 basis points year over year. Operating margin improved to 43.1%, rising 170 basis points sequentially and 500 basis points YoY, while net margin came in at 38.6%.
Management did caution, however, that 2026 expenses will grow faster than revenue as depreciation, energy costs, and data center operating expenses rise with the scale of new infrastructure. If revenue lands near $230 billion in 2026, above current consensus of $215 billion, operating margins could dip toward 34-36%, down from ~39-40% today. Even so, Meta’s high cash generation and potential partnerships for data center development give it multiple levers to manage this growth without compromising financial stability.
Conclusion:
Meta’s Q2 could quietly become the company’s inflection point after a weak Q1. Impressions rebounded, pricing held firm, and ARPP was up $2 YoY, driving the Company’s largest top-line surprise in nearly four years. Guidance for Q3 sets up another quarter of >20% growth, cementing the case that Meta’s core business is back in growth mode.
Notably, Meta’s AI spend is already paying off. Its investments are directly linked to revenue growth through its ad platform, creating a virtuous cycle that reinforces itself with every incremental improvement in AI performance. While 2026 expenses will pressure margins in the near term, Meta is entering this next phase from a position of extraordinary strength: a core business growing north of 20%, is cash flow positive even after $100 billion in capex, and offers an AI roadmap that offers quicker monetization.
