Jack Dorsey's Block posted a sharp rise in first-quarter profit, lifted by continued consumer spending.

The company reported adjusted earnings of $513 million, or 85 cents per share, beating the year-ago figure of $355 million, or 56 cents per share.

Shares of the Oakland-based fintech jumped 10.4% in after-hours trading.

A stable job market, wage gains, and larger tax refunds kept Americans spending through the first three months of the year. Gas station receipts also saw a boost, as the U.S.-Israeli conflict with Iran pushed up fuel prices.

Block's gross profit surged 27%, fueled by strong performance across both Cash App and its Square merchant business.
