Reddit (RDDT) Q4 2025 earnings review
The Profitability Switch Has Flipped
Reddit delivered a blowout quarter, proving its business model scales exceptionally well. Revenue growth accelerated to 70% YoY ($726M), but the real story is the bottom line: Net Income hit $252M (35% margin) compared to just $71M a year ago. The company is generating massive cash ($264M FCF) and authorized a $1B buyback, signaling management believes the stock is undervalued despite recent gains. While the core Ad business is on fire (+75%), the 'Data Licensing' narrative has stalled significantly.
🐂 Bull Case
SaaS investors look for the 'Rule of 40' (Growth + Margin). Reddit smashed this with a combined score of ~115 (70% Revenue Growth + 45% Adj. EBITDA Margin). This level of profitable growth is rare in the current market.
Advertising revenue accelerated to 75% growth. 11 of the top 15 verticals grew 50%+. The rollout of 'Reddit Max' (AI automation) and lower-funnel tools is successfully capturing budget share.
🐻 Bear Case
The AI data licensing narrative hit a wall. 'Other Revenue' grew only 8% YoY to $36M. Sequentially, this line item has been flat ($35M in Q2, $36M in Q3, $36M in Q4), suggesting no major new deals were signed.
Q1 Guidance implies a significant sequential revenue drop from $726M to ~$600M. While Q1 is seasonally weak for ads, a ~17% sequential decline is steep for a high-growth company.
⚖️ Verdict: 🟢🟢
Strong Buy. Reddit has successfully pivoted from a high-growth cash burner to a high-growth cash printer. The stagnation in data licensing is a concern, but the core advertising engine is performing so well that it renders the AI narrative a 'nice to have' rather than a necessity.
Key Themes
Operating Leverage is Kicking In
Accelerating. Reddit is demonstrating massive operating leverage. Revenue grew 70%, but Costs of Revenue only grew ~84% (high due to volume), while R&D expense actually flatlined (+5%) and G&A decreased slightly. This discipline allowed Gross Margins to stay elite at ~92% while converting incremental dollars straight to profit.
Data Licensing (AI) Revenue Stalls
Decelerating significantly. 'Other Revenue,' which houses the high-profile data licensing deals for AI training, came in at $36M, up only 8% YoY. This is a dramatic slowdown from the 66% growth seen in Q1. Sequentially, revenue has been flat for three quarters, indicating the initial rush of big-ticket deals (Google/OpenAI) has not been followed by a second wave of major signings.
International Monetization Unlocked
Accelerating. International revenue grew 78% YoY, outpacing the US (+68%). Machine translation (now in 35 languages) is driving user growth, and the sales team is effectively monetizing that traffic. International ARPU jumped 38% to $2.31, proving that Reddit is not just a US phenomenon.
Search Volume Explosion
Stable/Growing. Management highlighted that over 80 million users search directly on Reddit every week (up from 60M a year ago). This is a critical funnel for 'high intent' traffic. The integration of 'Reddit Answers' (AI search) into core search is driving query volume. This positions Reddit to compete directly with traditional search engines for query share.
Authenticity as the Product
Management is leaning hard into the 'Dead Internet Theory' defense. As the web fills with AI-generated 'slop,' Reddit is positioning itself as the only place for 'real community' and 'trusted opinions.' They are rolling out verification for brands/users to cement this differentiation.
Other KPIs
Stable. Growth remains healthy at 19% YoY, though slightly lower than the 21% seen in Q2. International DAUq (+28%) is growing 3x faster than US DAUq (+9%).
Accelerating. ARPU surged 42% YoY. This indicates much better ad-load management and pricing power. US ARPU specifically crossed the double-digit mark at $10.79 (+53%).
Accelerating. Conversion from Net Income ($252M) to FCF ($264M) is excellent (over 100%). The company is now sitting on ~$2.5B in cash/securities, enabling the new $1B share repurchase program.
Guidance
Decelerating. The midpoint ($600M) implies ~40% YoY growth (vs Q1'25 $428M). While 40% is strong, it is a deceleration from the 70% growth in Q4, and a significant sequential step down from $726M, reflecting post-holiday seasonality.
Stable. Midpoint implies a ~36% margin. This is lower than Q4's 45% (seasonal revenue dip impacts margin leverage) but remains highly profitable compared to historical Q1s.
Key Questions
Data Licensing Stall
Other Revenue has flatlined at ~$36M for three consecutive quarters. Does this imply you have saturated the market for large-cap LLM training deals, or are new deals just delayed?
Sequential Revenue Drop
Guidance suggests a ~17% sequential drop in revenue for Q1. Is this purely seasonal ad-spend reduction, or are you seeing any macro weakness or pricing pressure starting 2026?
Buyback Rationale
With the stock likely near highs after these results, why authorize a $1B buyback now rather than investing more aggressively in R&D or M&A, specifically in ad-tech or AI tools?
