Pinterest, Inc. (NYSE:PINS) is one of the most undervalued AI stocks to buy now.

On February 18, 2026, Pinterest, Inc. (NYSE:PINS) reported a bullish outlook for the first quarter, after incorporating the impact from its December 2025 acquisition of tvScientific.

Incorporating synergies from the move, Pinterest, Inc. (NYSE:PINS) now projects revenue of $958-$978 million, up from its prior range of $951-$971 million. However, the revenue guidance upgrade was accompanied by a reduction in EBITDA guidance, driven by acquisition costs and cash outlay. The company now forecasts $163-$183 million, down from an earlier range of $166-$186 million. Meanwhile, the midpoint revenue guidance exceeds the analyst consensus of $964.9 million.

Previously, on February 13, 2026, Pinterest, Inc. (NYSE:PINS) saw a share price decline wipe off $2 billion of its $12.52 billion market value. The 21% share price decline took the shares to the low they reached during the pandemic.

The plunge reflects the weak sentiment surrounding tariff-driven pullbacks in major U.S. retailers’ spending and intensifying AI competition.

With its visual discovery platform, Pinterest, Inc. (NYSE:PINS) allows users to design and shop image-based content. The company’s monetization strategy is tied to performance-driven digital advertising solutions enhanced by AI tools.
