Shares of Magnite jumped 8.6% to $22.45 after the digital advertising middleman posted second-quarter results that, beneath a mixed headline, revealed an increasingly profitable business reshaping itself around streaming television. Sales rose 11.2% year on year to $192.8 million , technically missing Wall Street's $196.4 million target, yet contribution ex-TAC — the company's key operating metric — rose 17% year-over-year to $189.6 million, roughly $10 million above consensus, while adjusted EBITDA climbed 30% to $71 million, expanding the margin to 37%. Investors focused on the profitability beat, not the revenue shortfall.

  • Streaming TV Now Generates More Than Half the Business — and It's Accelerating. CTV revenue was $100.1 million, or 52% of the total, up from $82.4 million and 48%. The 36% growth rate in CTV ad sales is the fastest in at least four quarters: the trajectory compares with 30% in Q1 2026 and 20% in Q4 2025. That acceleration matters because it signals Magnite is capturing a larger share of advertisers shifting budgets from traditional TV to streaming — a trend that shows no sign of stalling.

  • The Real Surprise Was Profitability, Not Revenue. Adjusted EBITDA of $70.6 million beat estimates of $63.12 million, a 36.6% margin and 11.8% beat.

Adjusted operating margin hit 26.4%, up 2.4 percentage points year on year , driven partly by AI-related cost savings in cloud spending. Free cash flow margin surged to 92.4% from 1.4% a year ago — an eye-popping swing that reflects both improved cash conversion and the absence of last year's large debt repayment.

  • Management Raised the Bar for the Full Year. Total contribution ex-TAC growth is now guided at 13%–14%, up from at least 11%; EBITDA growth above 20%, up from mid-teens; EBITDA margin at least 37%, up from 35.5%; and free cash flow growth in the high 40% range, up from mid-30%.

Analysts responded: Susquehanna raised its price target from $22 to $30, and Rosenblatt increased to $40.

  • The Risk Hiding in Plain Sight: One Growth Engine, One Shrinking One. Streaming inventory is absorbing television budgets at a pace that outstrips the wider market, while open-web display volumes are being eroded. Magnite's non-streaming segment only just returned to growth after declining 5% last quarter. If display deteriorates again, the company's entire growth story rests on CTV alone — a single bet that, for now, is working spectacularly.
