Pinterest downgraded to sell amid slowing revenue growth and uncertain turnaround timeline

Pinterest has been downgraded to a 'sell' rating due to ongoing revenue growth slowdown and unclear prospects for recovery. In Q4 FY25, average revenue per user (ARPU) growth slowed to 2% as advertising prices weakened and major retail advertisers reduced budgets due to tariffs. Management's efforts to diversify advertisers and innovate with AI lack clear short-term impact on revenue or margins. The upcoming Q1 earnings report is expected to show further declines in revenue and profit, signaling market share losses to bigger competitors. Despite a low valuation, the risk-reward profile remains unattractive without signs of revenue acceleration or a sustainable stock rerating soon.
