Grab Holdings (NASDAQ: GRAB) shares are down more than 8.5% Thursday after the company reported its fourth-quarter earnings, in which it announced its first-ever share buyback program.

The company reported fourth-quarter earnings of $0.01, $0.02 better than the analyst estimate of ($0.01), while revenue for the quarter came in at $653 million versus the consensus estimate of $633.67 million. However, FY2024 revenue guidance of $2.7 billion to $2.75 billion was below the consensus of $2.82 billion, sending GRAB's shares lower.

Meanwhile, the Singapore-based company's board of directors has authorized a share repurchase program, under which the company can repurchase up to $500 million worth of its outstanding Class A ordinary shares.

The company also approved the full repayment of its outstanding Term Loan B. GRAB expects the repayment to create "significant interest expense savings."
