DSP Information Technology 3 recaps
Next earnings: March 10, 2027 (estimated) · full calendar
Q3 2026 Nov 12, 2026

Viant shares fell 12.2% after earnings, despite Q3 results above the company’s guidance ranges. The likely disappointment is the cautious outlook: Q4 contribution ex-TAC guidance implies a sharp sequential slowdown from Q3, with the midpoint indicating roughly 8% quarter-over-quarter growth versus 27% year-over-year growth in Q3.

Key takeaways
  • Q3 revenue rose 29% year over year, above the midpoint of guidance; contribution ex-TAC increased 27%, above the high end.
  • Adjusted EBITDA grew 24% to $19.8 million, also above the high end of guidance.
  • CTV advertiser spend increased nearly 40% year over year, and management cited growth across most verticals.
  • Q4 guidance calls for contribution ex-TAC of $76.5 million to $78.5 million and adjusted EBITDA of $12.5 million to $14.5 million; the contribution ex-TAC midpoint is below Q3’s $72.9 million only modestly, but signals slower sequential growth than Q3’s year-over-year pace.
  • Viant closed its acquisition of Waymark, a generative AI video-creative platform focused on CTV; management described potential benefits, but did not quantify its expected financial contribution.
Q1 2026 May 12, 2026

Shares of Viant Technology declined 12% following the earnings report, reflecting investor disappointment likely driven by cautious forward guidance and concerns over sustainability of current growth momentum, despite strong first quarter results.

Key takeaways
  • Revenue rose 25% year-over-year, surpassing the high end of guidance.
  • Contribution ex-TAC increased 18% year-over-year, above midpoint guidance.
  • Adjusted EBITDA was $9.8 million, up 81% year-over-year and above guidance range.
  • CTV spend exceeded 50% of total ad spend, with contribution ex-TAC growing over 40% year-over-year in this segment.
  • Despite strong Q1 metrics, the 12% stock drop signals investor skepticism about guidance sustainability or margin outlook ahead.
Q3 2025 Nov 12, 2025

Viant Technology Inc. reported a robust third quarter, achieving record metrics with a 7% year-over-year revenue increase and a 12% rise in contribution ex TAC, surpassing guidance expectations.

  • Landmark multiyear partnership signed with Molson Coors, enhancing Viant's footprint as a leader in autonomous advertising for the open internet.
