MercadoLibre surged 11% in overnight trading after the Latin American e-commerce and fintech giant’s profit far surpassed estimates.

Net income in the fourth quarter was a record $639 million compared with a $406 million median estimate from analysts, according to data compiled by Bloomberg. The $6.1 billion of revenue in the quarter also beat expectations.

Shares of Celsius Holdings, Inc. surged 34% after the company said it would buy rival energy-drink maker Alani Nu for $1.8 billion, and it logged higher-than-expected profit and revenue in the fourth quarter.

Celsius's growth has slowed over the past year, while the smaller Alani Nu has made some of the biggest market-share gains in energy drinks, The Wall Street Journal reported, citing NielsenIQ data compiled by Jefferies.

The deal, made up of both cash and stock, is expected to "further strengthen Celsius' position as an innovative leader in the large, growing global energy category," Chief Executive John Fieldly said.

The acquisition came as Celsius swung to a net loss of $18.9 million, or 11 cents a share, in the quarter ended Dec. 31, compared with a profit of $50.1 million, or 17 cents a share, a year earlier.

Adjusted per-share earnings were 14 cents, topping the 12 cents that analysts surveyed by FactSet expected.

Revenue fell 4%, to $332.2 million, but came in ahead of the $326.2 million that analysts modeled.

Block's fourth-quarter profit fell short of estimates as spending growth during the holiday season and gains from a post-election surge in bitcoin lagged expectations, sending the payment firm's shares down 6% in overnight trading.

While a robust labor market and steady wage growth have supported consumer spending - bolstered further by holiday travel and retail splurges - uncertainty surrounding trade policy under a new administration and the Federal Reserve's rate cuts has kept sentiment in check.

Block's results come on the same day that retail giant Walmart fueled concerns over consumer spending with a sales and profit forecast for the current year that fell short of Wall Street estimates.

Block CEO Jack Dorsey, however, emphasized the payments company's attempts to streamline operations and said investing in artificial intelligence tools was a top priority.

"Our number one initiative on our strategic roadmap ... is to invest heavily in building applied AI tools to remove the toil of mechanical tasks," he said.

The company reported a profit of 71 cents per share, excluding one-time costs. Analysts had expected a figure of 87 cents per share, according to estimates compiled by LSEG.

Its transaction-based revenue was $1.68 billion, compared with the expectations of $1.70 billion. Bitcoin revenue of $2.43 billion also missed estimates of $2.62 billion.

Nu Holdings Ltd shares are trading 8% lower in overnight trading.

“We advanced in all of our priorities with significant strides in our High-Income strategy in Brazil, expanded our footprint in Mexico, and broadened our portfolio with NuCel and NuTravel,” said Nubank founder and CEO David Vélez.

“As we prepare to scale up our products and services globally, we remain focused on execution, customer-centric innovation and sustainable growth in our current markets.”
