Contribution ex-TAC (traffic acquisition costs) rose 12% to $130.6 million with strong growth in connected TV (CTV), or ad-based streaming, which was up 18% to $54.9 million.

On the bottom line, adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) increased from $23.3 million to $25 million, and adjusted earnings per share ticked up from $0.04 to $0.05, which was better than expectations of breakeven.
