Beach Energy (ASX:BPT) free cash flow (FCF) outlook remains under pressure despite the expected boost in sentiment from the imminent start-up of its Waitsia project in Western Australia, according to a Tuesday report by Jarden Research.

Rising operational costs and weaker production have reduced the company's FCF generation potential, Jarden said.

Market expectations for the company's cumulative free cash flow for the fiscal year 2026 to fiscal year 2030 have fallen to AU$1.5 million from AU$3.7 billion two years ago, Jarden added.

The firm maintained the company's underweight rating while cutting its price target to AU$1.07 from AU$1.10.

Shares of the company rose 3% at market close.
