Flight Centre Travel Group (ASX:FLT) downgraded its profit guidance for fiscal 2025, citing the impact of new US policies, according to a Monday filing with the Australian bourse.

The leisure and corporate travel manager now sees FY2025 underlying profit before tax of AU$300 million to AU$335 million, compared with a previous target of AU$365 million to AU$405 million, which would have represented growth of around 14% to 27% on the prior fiscal year.

"The recent US developments have exacerbated the volatile trading conditions experienced throughout the year, leading to lower-than-expected [total transaction value (TTV)] growth in core brands and impacting super over-rides, overall margins and operating leverage in these larger brands given most TTV growth has occurred in lower margin businesses," the company said in its filing.

Meanwhile, it announced a AU$200 million on-market share buyback for a period of 12 months starting around May 12.
