LISBON, Oct 27 (Reuters) - Portugal's second-largest retailer Jeronimo Martins posted on Wednesday a near 20% rise in third-quarter net profit, boosted by robust sales in its key market Poland and a rebound at home with the easing of coronavirus restrictions.

The company reported a net profit of 137 million euros ($159 million) between July and September, when Portugal and Poland where lifting the curbs put in place to control the pandemic, from 115 million euros a year ago.

Total sales rose 8.7% to 5.3 billion euros driven by Poland's food retail leader Biedronka.

In Portugal, sales by the Pingo Doce supermarket chain rose 2.7% to around 1 billion euros.

Chief Executive Officer Pedro Soares dos Santos said in a statement that "with the Christmas season approaching and despite the uncertainty on the pandemic evolution, the results attained so far reinforce our confidence in achieving the growth targets set for the year."

Earnings before interest, taxes, depreciation and amortisation (EBITDA) grew 8.8% to 429 million euros in the third quarter.
