After that, I will provide some final remark, and then we will open the queue to your questions. As you could see from our release yous- yesterday, we are pleased to share our third quarter results, where we observe solid demand and high historic figures as we keep our core finance margin at world-class level. inaudible the strong movement experienced in cement sales since the start of the recovery in mid 2020 has reached level most equivalent of the- those seen in record industry years. Our high efficient production standard enabled us to delivery another robust quarter. Despite the impact of the normalization of operation and the subsequent effect of regular seasonality maintenance cost and the higher energy input in our ISAC and EBITDA margins. Despite these effects, when measured in US dollar, our ISAC and EBITDA increased to 51 million from 48 million in third quarter 2020, even improving the result from last quarter, keeping the US dollar per ton above $30. Finally, regarding the expansion project of L'Amali, we are delivering cement to the market, and already seeing promising result from the first production budget. We expect to show its benefits in the coming quarters. I will now hand off the call to Marcos Gradin, who will lead you through our market review and financial results. Please, Marcos, go ahead. Thank you, Sergio. Good day everyone. As you can see on slide four, leaving behind a deep drops of GDP in 2020, we saw a sharp recovery in the second quarter, and an improvement in 2021 GDP estimated growth, reaching 8.3%. Construction activity measured by the ISAC also had a strong performance in recent months, starting to present a more moderate growth, as third quarter to 2020 showed the start of the post-pandemic recovery. Regarding cement national industry sales, they had kept on growing strongly. Even above our previous expectation. Consolidated in high figures, with 10 months accumulated volumes almost reaching industry's year record, less than 1% down from the same period of 2017. Although we do not see large private infrastructure projects, purchases recur mostly on the back of smaller projects. So, when breaking down the consumption by dispatch mode, we observe figures in line with historical pre-pandemic average. Certainly, the economy as a whole still faces different challenges, particularly on the market economic outlook that may impact our future growth expectations. Turning on to slide five for a review of our top-line performance by segment. Consolidated revenues increased year on year by 8.5%, mainly reflecting the continued recovery of the other segments more affected by the pandemic restrictions and the growth of our core seven business. Seventh measure inaudible on line segment, was up 2.4% with margins expanding 8.4% with softer pricing dynamic. Concrete and aggregates show sharp revenues recovery of 117%, or 47% year on year, respectively. As we mentioned before, these segments suffer more deeply the effects of the pandemic restrictions. In the case of concrete volume expansion of 111%, was underpinned by a positive price in recovering performance. Regarding aggregates, the segment volume was up 7.2%, boosted by recovering pricing, and a positive pricing mix. Finally, regular revenues increased by 25.4% in this quarter, versus the same quarter in 2020, as the higher transported volumes were coupled with a good price in performance and a positive product mix. Moving on to slide seven. Consolidated growth profit for the quarter slightly declined, 0.1% year on year, with margin contracted by 222 basis points, mainly impacted by the demonetization of seasonality cost and higher energy inputs. Seventh growth margin contracted by five- 577 basis points from 35.5% to 29.8% with the comparison affected by regular inaudible maintenance cost this quarter against the third quarter of 2020, with the maintenance schedule affected by the pandemic restrictions. We also experienced some pressure and… from seasonal energy charges as winter production in 2020 was abnormally low, due to the sharp drop in demand in last year. For the next year, the brand new line built in L'Amali plant will give us a flexibility to maximize production out of the winter months, avoiding higher energy charges. inaudible expenses a percentage of revenues remain almost flat, decreasing by five basis points to 7.6% from 7.7%, mainly due to cost inaudible from higher sales volume. Please turn to slide eight. Our adjusted EBITDA was down 9.1% in the quarter, reaching $4.7 billion pesos with consolidated EBITDA margin, contracted by 512 basis points to 26.4%, mainly explained by lower a seventh segment adjusted EBITDA and the impact of the recovery of the other segments. Which, as they have lower margins, contributed negatively to the consolidated margin. In a nine-month basis, adjusted EBITDA margin expanded 55 basis points to 30.7%. When measured in US dollars, our third quarter EBITDA reached 51 million dollars, up 6.5% from 48 million in the same quarter a year ago, and sequentially. Seventh segment adjusted EBITDA margin contracted by 484 basis points to 29.5%, mainly due to the impact of regular seasonality maintenance and winter energy costs, coupled by a softer price in dynamic, partially offset by the increase in sales volume. In a inaudible basis, EBITDA remains at a top-notch level of $30. Concrete adjusted
