Nov 21 (Reuters) - Uruguayan fintech dLocal's shares tumbled in after-hours trading on Tuesday after it missed third-quarter earnings estimates and said its finance chief would step down, the latest executive shakeup at the payments provider.

DLocal's shares plunged nearly 13% after the bell in New York, shaving off some $702 million of market value.

The company reported third-quarter profit of 13 cents a share, missing the LSEG analyst consensus estimate of 15 cents per share.

Profit rose 25% from the year-ago quarter to $40.4 million, but was dragged down by foreign-exchange impacts, inflation in Argentina and stock-based compensation. Excluding those items, company reported adjusted profit of $49.2 million, dLocal said.

"This is the first time dLocal has adjusted earnings for those items," analysts at J.P. Morgan said, arguing those items were likely to recur or were required to be reported under international accounting standards.

The company also said that CFO Diego Cabrera was leaving the company "to pursue new opportunities," without explaining further.

It added that Cabrera would stay on through the first quarter of next year to ensure a smooth transition, though it did not name his replacement.

Other new hires, such as a principal accounting officer and a head of government relations, will also join the team, co-CEO Pedro Arnt said in a statement.

Arnt was named co-CEO in August, amid a challenging period for the company following a short-seller report published at the end of last year accusing dLocal of potential fraud, which dLocal has denied.

The company has also denied media reports that the Argentine government was investigating it for "improper maneuvers" around fund transfers abroad, telling Reuters in May it had received a request for information from Argentine customs authorities.

DLocal said on Tuesday that its cash on hand had dipped quarter-over-quarter, in part due to the "repatriation of funds in Argentina that were outstanding."

The company had told Reuters in September it was set to "pause" its rapid expansion plans to focus on strengthening existing operations in over 40 countries, hinting at a new phase for the fast-growing firm.

Revenues in the third quarter were up 47% year-on-year to $163.9 million on "sound growth across all verticals," particularly in Brazil and Mexico.

Growth in total payment volume slowed from the second quarter to rise 69% annually, which J.P. Morgan analysts said was "somewhat expected" on headwinds caused by currency conditions in Nigeria. (Reporting by Kylie Madry; Editing by Sarah Morland and Deepa Babington)
