MEXICO CITY (Reuters) -Walmart's Mexico and Central America unit posted a 14.4% year-on-year rise in its first-quarter net profit on Wednesday, fueled by strong same-store sales growth across its markets.

Walmart de Mexico, the country's largest retailer, posted a net profit of 13.18 billion pesos ($797.5 million), above the average forecast of 12.93 billion pesos seen by analysts polled by LSEG.

The company, also known as Walmex, said in a filing to Mexico's main stock exchange that same-store sales grew 9.4% in Mexico and 8.0% in Central America.

Quarterly revenue at the department store and grocery chain rose 9.8% from the same quarter a year earlier to reach 226.19 billion pesos, beating the mean estimate of 224.41 billion from analysts polled by LSEG.

Earnings before interest, tax, depreciation and amortization (EBITDA) for the quarter rose 10.3% to 24.62 billion pesos.
