Magnite Inc. Reports Robust Q4 2025 Performance and Announces $200 Million Share‑Buyback Program

Magnite Inc. (NASDAQ: MGNI), the world’s largest independent sell‑side advertising platform, today released its financial results for the quarter ended December 31, 2025, and the full year. The company’s data underscore a continued trajectory of growth and operational efficiency in a market that is increasingly demanding sophisticated, data‑driven advertising solutions.

Revenue and Contribution Growth

  • Q4 2025 Revenue: $205.4 million, up 6 % YoY.
  • Contribution ex‑TAC(1) (Q4): $195.1 million, a 8 % increase YoY.
  • Full‑Year 2025 Revenue: $870.3 million, reflecting a 5 % rise on the 2024 figure.
  • Contribution ex‑TAC(1) (FY 2025): $820.7 million, up 7 % from FY 2024.

These figures illustrate the firm’s resilience in the face of broader market volatility, with incremental revenue driven by a stronger mix of high‑margin programmatic video and connected TV (CTV) placements.

CTV Momentum

Magnite’s CTV contribution in Q4 grew by 32 % (ex‑political), a 20 % increase in absolute terms, underscoring the continued shift of advertisers toward high‑impact, premium inventory. This momentum aligns with the company’s strategic focus on expanding its cloud‑based, real‑time bidding capabilities that leverage big‑data analytics to deliver precise audience targeting.

Earnings Efficiency

  • Adjusted EBITDA margin (Q4): 43 %.
  • Adjusted EBITDA margin (FY 2025): 40 %.

The narrowing margin gap from the prior year reflects tighter operating leverage and an improved cost structure, reinforcing Magnite’s position as a profitable, high‑margin advertising technology provider.

Capital Allocation Initiative

In a decisive move to enhance shareholder value, Magnite announced a $200 million stock‑buyback program. The program will be executed over a 12‑month period, with the company committing to repurchase shares at market price, thereby increasing earnings per share and returning capital to investors without diluting equity.

Forward Outlook

Magnite’s management reaffirmed its confidence in sustained growth across programmatic video, CTV, and emerging inventory formats. The firm plans to deepen its data‑science capabilities, expand its global reach, and pursue selective strategic acquisitions that reinforce its market leadership.

Given the company’s robust financial performance, expanding CTV footprint, and proactive capital‑return strategy, Magnite’s trajectory points to continued resilience and value creation for stakeholders in the evolving digital advertising ecosystem.
