ROME (Reuters) -Italy's economy posted marginal growth of 0.1% in the third quarter from the previous three months thanks mainly to exports, national statistics bureau ISTAT said on Friday, revising up a previous printout that pointed to stagnation.

Year-on-year, third quarter gross domestic product in the euro zone's third largest economy increased by 0.6%, above the 0.4% estimate ISTAT made on October 30.

* Net trade contributed 0.5% to quarterly GDP growth, while investments and consumer spending each contributed 0.1%. These components marginally outweighed a 0.6% negative contribution from a decline in inventories.

* Imports rose 1.2% from the second quarter, while exports were up 2.6%, despite concerns about a negative impact from U.S. trade tariffs.

* Consumer spending was up 0.1% and investments rose 0.6%.

* So-called "acquired growth at the end of Q3 stood at 0.5%, meaning this will be the full-year growth rate if GDP stagnates in the fourth quarter.

* Prime Minister Giorgia Meloni's government is officially forecasting 0.5% growth this year, following the 0.7% rate in 2024.
