Pinterest has finalized its acquisition of tvScientific, marking the platform’s most significant move in the ad-tech space since 2022. This deal, valued by industry analysts in the range of **$300 million** to **$350 million**, directly integrates performance-driven Connected TV (CTV) capabilities into Pinterest’s existing advertising ecosystem. The transaction has immediate financial implications, as Pinterest recently raised its first-quarter 2026 revenue guidance to a range of **$958 million** to **$978 million**. This update, which incorporates partial-quarter contributions from tvScientific, reflects a year-over-year growth target of **11%** to **14%**. The company also projected Adjusted EBITDA between **$163 million** and **$183 million** for the same period. Strategically, the acquisition addresses the rising demand for accountability in television advertising. By merging its high-intent shopper data with tvScientific’s outcome-based engine, Pinterest enables brands to track whether a TV ad leads to a specific purchase. This "closed-loop" measurement is critical as the U.S. CTV ad market is projected to reach **$37.95 billion** by the end of 2026. The integration focuses on Pinterest’s "Performance+" suite, an AI-powered tool designed to automate media buying and optimize campaigns across multiple screens. With over **600 million** monthly active users and a **14%** increase in 2025 annual revenue, Pinterest is positioning itself to capture a larger share of performance budgets. This shift is particularly relevant as **69%** of viewers now use a second screen, such as a mobile phone, while watching TV. While the deal strengthens Pinterest’s competitive stance against larger players, the company faces a complex macroeconomic environment. Executives have noted potential headwinds from new tariffs and intense competition from Meta and Google, which may impact ad spending volatility. Despite these challenges, the platform maintains a strong liquidity position with a cash and equivalents balance of approximately **$2.7 billion**. This acquisition signals a broader industry trend where the lines between social media performance and traditional brand awareness are disappearing. By owning the underlying technology for CTV attribution, Pinterest aims to offer advertisers a unified system that connects mobile intent with large-screen impact, moving beyond "views and vibes" toward measurable return on ad spend.
