Nov 4 (Reuters) - Pinterest ( PINS ) forecast fourth-quarter revenue slightly below Wall

Street estimates on Tuesday, signaling rising competition from larger platforms such as Meta

during the holiday shopping season.

The company expects quarterly revenue between $1.31 billion and $1.34 billion, with the

midpoint marginally below analysts' average estimate of $1.34 billion, according to data

compiled by LSEG.

Pinterest's ( PINS ) results follow reports from digital ad bellwethers, including Google-parent

Alphabet, Meta and Reddit ( RDDT ), which posted upbeat third-quarter revenue

on robust ad spending.

Large platforms such as TikTok and Meta's Instagram and Facebook remain the top choices for

marketers, thanks to their massive user bases and sophisticated artificial intelligence tools

for campaign creation.

The image sharing platform also offers an AI-powered Performance+ ad suite to marketers

for creating personalized and automated campaigns.

Pinterest ( PINS ) had said it saw lower spending by Asia-based e-commerce retailers in the U.S.

after the end of the

"de minimis" exemption

, though some shifted budgets to Europe and other regions.

The end of the U.S. duty-free import provision for low-value shipments from China and Hong

Kong has prompted some Chinese retailers, such as Temu and Shein, to adjust their marketing

budgets.

Pinterest's ( PINS ) global monthly active users are rising, with the company hitting an all-time

high of 600 million in the third quarter.

The company's revenue grew 17% to $1.05 billion in the third quarter, aligning with

analysts' estimates and marking its return to the billion-dollar revenue level first attained in

the holiday quarter of 2024.

Adjusted profit per share came in at 38 cents for the quarter ended September 30, missing

estimates of 42 cents.
