Viant Technology Stock Jumps After Canceling Public Share Offering

Shares of Viant Technology Inc. (NASDAQ:DSP) jumped more than 19% in premarket trading Friday after the company announced the cancellation of a significant public stock offering.

Offering Withdrawn

In a statement on September 17, 2026, Viant said that it and a selling stockholder had decided not to proceed with a previously announced underwritten public offering. The company cited "current market conditions" as the reason for the withdrawal. No shares were sold as part of the planned deal.

The proposed offering included:

• 8,500,000 shares of Class A common stock to be sold by the stockholder.
• A 30-day option for underwriters to purchase up to an additional 1,275,000 shares from Viant Technology itself.

Ad

As a result of the cancellation, Viant does not plan to file a final prospectus supplement with the Securities and Exchange Commission for this offering.

Market Impact

The market reacted positively to the news, sending the stock up 19.3% in premarket activity. The cancellation of a secondary offering is often viewed favorably by investors because it removes the threat of immediate share dilution.

A large influx of new shares, as was planned, increases the total number of shares outstanding, which can decrease the ownership percentage and earnings per share for existing stockholders. By scrapping the offering, Viant has alleviated these near-term concerns, leading to a relief rally in its stock price.
