Thank you, Margarita. Hello, everyone and thank you for joining our conference call. I hope you all are safe and well. In the interest of time, I will summarize the latest events and financial figures. For more details, you can check our earnings release or feel free to contact us. Our CEO, Mr. Mariani and CFO Mr. Cohen are both here and joining us for the Q&A session. Let's start commenting on the quarters highlights. First, we recorded more than 60% year-over-year sales increase thanks to the Plan Gas winter peak, Pampa new PPA and commodity price hikes. Moreover, our E&P business set another record as our flagship block El Mangrullo achieved full all- time high gas production of 226 million cubic feet per day two weeks ago, contributing to an increase in our overall production. This is a significant milestone for our E&P and the country's big demand during the winter. The record is more than 30% higher than last year's July and three times 2016 production level showing the competitive productivity of high gas formation formation. Also, the quarter's performance is supported by higher prices even higher than pre pandemic levels explained by winter seasonality Plan Gas and commodity prices. Legacy prices are also boosted by the awaited increasing pesos but the result is moderated in dollar terms as a result of devaluation. Our petchem business achieved another outstanding quarter not only benefited by prices but also a recurring demand. The regulator cleared the sale of Edenor’s control and the management change took place by the end of the quarter. Therefore, we ended a chapter and collected proceeds to keep focusing on our power and gas businesses where there is cash generation. The final payment is due one year from closing. But not -- last but not least. We keep strengthening our financial position by reducing our leverage thanks to our free cash flow generation reaching almost $1 billion in net debt. A healthy balance sheet, coupled with a comfortable debt profile makes a great defensive strategy in challenging Argentina. Now, let's move on the quarter's key financial takeaway. Let's only focus on the continuing business. Revenues increased 52% year-over-year to $456 million in the quarter, mainly driven by Plan Gas, winter seasonality and new PPA and high commodity prices boosting petrochemicals and PGA liquids, though partially offset by lower legacy prices in dollar terms, as well as tariff fees and deval effect over utility businesses. In Q2 2021 roughly over 80% of our sales and EBITDA were dollar linked mainly from our core businesses PPA power capacity, followed by E&P. The adjusted EBITDA amounted to $241 million, 79% higher year-over-year mainly driven by the same reason detailed before plus production efficiencies and dilution of peso linked expenses due to the devaluation effect. Quarter-on-quarter EBITDA increased by 18% mainly explained by winter gas prices and the retracted rate in legacy prices offset by outages at close power units and petrochemical scheduled maintenance in the reforming plant. Therefore, oil and gas is regaining exposure by taking a 48% share, as we show on the right below, like while electricity takes 52% of the consolidated adjusted EBITDA. Moreover, in Q2, CapEx was double year-over-year more than double year-over-year and 66% up quarter-on-quarter mainly explained by Plan Gas commitment during the winter, and Barragan's expansion offset by the commissioning of Genelba's new CCGT in July last year. Moving on to the power generation segment, as you see, in slide 5, we posted an EBITDA of $121 million in Q2 2021, 26% higher than last year, mainly contributed by Genelba's CCGT, higher B2B electricity sales, legacy prices update and the devaluation impact on our petchem nominated expenses. These effects were offset primarily by the dilution of in dollars of legacy prices, higher energy purchases to cover the b2b contracts and operation outages in June. Quarter-on-quarter EBITDA increased by 5% mainly due to the spot price this update retroactively to February, offset by the off peak pricing for spot energy and lower dispatched in Q2 '21. Spot energy comprises 59% of our capacity, but represented only 17% of our power generation EBITDA therefore, it will be keep shrinking unless the next inflation adjustment outpaces evaluation. Still it is key to continue with the proper maintenance of this plan underpay considering the contribution to the grid. Moving to the operating figures for generation in 2018 to 2021 was 10% up year-on-year in line with the great recovery like Q1 nationwide demand is back to pre pandemic levels, mainly driven by industry, which is a good news for GDPS credit, we recorded higher dispatching Genelba's new CCGT thermal plants firing alternative fuels and increasing -- increased load factor from wind farms offset by lower gas fire dispatch because there's no gas, limited gas. However, quarter-on-quarter generation was 14% down driven by the full system and outages. Keep in mind that the power generation business model relies on capacity payments. So lower dispatch does not impact the revenue making as long as the availability for scanning especially for PPA based energy, the availability rates in Q2 '21 reached an outstanding 95.8% slightly lower year-on-year mainly due to Genelba partial outages in June, which fully received last month. Regarding our expansion, the closing to CCGT at Ensenada Barragan is almost half away at that we are currently working on the boilers in the cooling tower water system and completing the steam turbines building enclosure, it can seem that around 1,500 people are at the site, working with COVID protocols and reviewing the critical equipment to achieve COV by the second quarter of 2020. One close, but total capacity will be 847 megawatts, become one of the country's most efficient thermal units, and Pampa's four operators CCGT. Moving to E&P results, on slide 7, we posted an adjusted EBITDA of $73 million in Q2 '21, recording that remarkable growth year-on-year, primarily driven by Plan Gas which rebounded the gas prices and volume because of we took commitments, in addition to higher oil prices and recoveries met. However, more royalties and from higher prices and increased world's drilling and completion activities offset the rise of EBITDA. Quarter-on-quarter the EBITDA more than double due to the winter effects offset by higher royalty. Efficiency wise, we recorded $25 million of listing costs 20% more than last year, due to well drilling and completion reactivation activities offset by higher productivity at competitive gas blocks, such as in El Mangrullo, higher oil production and the devaluation. By BOE produced we kept below $6 of listing costs, 10% higher in year-over-year but very similar quarter-on-quarter. Our global production increased 9% year-on-year and quarter-on-quarter mainly again, driven by the Plan Gas. Oil demand -- locked down but still hasn't reached pre pandemic levels. As a result, we averaged almost 48,000 barrels of oil equivalent per day of which 90% is gas. On the oil side, we represented 22% of the revenues in the quarter, volumes saw increased by 11% year-over-year to 4,500 barrels per day explained by export demand. The 40% quarter-on-quarter increase is primarily due to export concentrated in the Q2. As per crude oil prices which are driven by the rent is almost tripled last year due to the lockdown while quarter-on-quarter remain similar. Our production is still down 1,000 barrels oil per day to the pre pandemic level. We expect to recover them gradually. Regarding gas as shown in the next slide. Our average sales average 264 million cubic feet per day in the quarter, 4% up year-on-year, driven by the Plan Gas PSA. Production could have been higher, but blockade during April 2021 affected the output impacting our employees and equipment daily operation. Therefore our production since May was slightly lower than the GSA commitment. But we still recover this month overproducing actually the target of 320 million cubic feet per day. In addition, Gas producers including Pampa were granted force majeure and so no penalties to pay. Quarter-on-quarter 9% increase is primarily explained by the beginning of the winter peak season and better B2B sales from industrial demand. Like in Q1, nationwide gas production during the quarter was only 1% down year-on-year, evidencing the Plan Gas effect. The demand is rising to pre pandemic level driven by the large users and retail consumption. Going back to our quarter production performance, El Mangrullo led the quarter's production growth contributed close to 70% of our overall gas. This block is wholly owned and operated by us with our standing productivity boosted by the temporary production facility we sold in back in May and reached all time high record by the end of July. During the course second quarter '21, our average price was $3.9 dollar per million BTU double year-on-year and almost 40% up quarter-on-quarter against by the Plan Gas winter peak. The b2b and spot prices out of this GSA also reflected the seasonality but haven't reached the Plan Gas level. As you can see right below the year-to-date sales are more diversified, similar to the country's breakdown. Gas retailers are also part of Plan Gas soared during winter because of their priority. Increasing its share to 30% compared to the last quarter last quarter 18%. Also we are working to grow our B2B sales with positive results increasing our market share as you can see in the site. The only segment shrinking its exports, which will be received for October with a taker pay deliveries to Chile. Regarding our E&P operation subject, we strengthened our investment recording $55 million during the quarter, almost three times higher than last year. This quarter was quite active drill and complete 11 Plan Gas well in line with the winter peak. As I say in the previous call, we are building the second gas treatment plant in El Mangrullo which will more than double the current capacity to reach 290 million cubic feet per day by the first half of next year. In all, we drilled four wells and completed five, all from -- Moving to the petrochemical business, this segment deliver another solid quarter, actually in four times last year EBITDA mainly explained by the significant rise on international prices, higher local virgin naphtha supply and demand growth linked to industry recovery offset by increased raw materials cost influenced by set reference prices and Plan Gas impact. The year-over-year sales volume increase was significant for all the products; sales quarter-on-quarter increased 22% because of our reforming plant seasonal maintenance. In addition, roughly 40% of the quarter sales were exported. Since the international prices are very volatile and seasonal. We do not expect this performance for the second half of the year. Before getting into cash and debt, we must highlight the solid cash flow generation reported during the quarter supported by the outstanding operating performance from all the businesses and improve profitability thanks to higher realized price. During Q2, free cash flow resulted roughly $72 million, $50 million more than last quarter. Notice that it is last year's quarter, notice that the working capital was negative, mainly driven by seasonal, higher seasonal billing and Plan Gas effect and to a lesser extent, the increasing collection days from CAMMESA. In addition, we collected an Edenor’s second sale installment and former Plan Gas receivable for a total of $64 million. We repay $71 million of mostly debt maturities and bought back shares for $11 million. So in total, we generated a net of $54 million achieving $462 million of cash position by the end of the quarter. Moving on to slide 11. This is life. Life shows consolidated figures, including our affiliates at ownership but let's keep focusing on this restricted group for covenant purposes. Things, Edenor was deconsolidated Pampa under IFRS is equivalent to the restricted group. The growth that's continued to decrease amounting to $1.5 billion as of June, 2021, 96% is in dollars up from the 91% last March. As we've been paying down all the shorts in debt most of the shorts and debt in peso. So dollar and. an average interest rate of 7.4% while the peso debt average is less than 37% interest rate. The average life remains at 46 years. As we said before the cash amounted to $452 million. This is 13% higher quarter-on-quarter. So, net debt decreased to $1 billion. In addition, the net leverage ratio improved from 2.3x to 1.7x due to the higher EBITDA. In the next 12 months, the company only faces less than $100 million of maturity, most in local currency. Moreover, our last peso bond matures by the end of this month, roughly $65 million. Therefore, we expect to keep using short term debt, strengthening our balance sheet. As a result, you can see this rating and rated our bonds to be C minus, fee origins and corporate are above the sovereign ceiling. So, this concludes our presentation. Now, I will turn towards to Margarita who will open the floor for questions. Thank you.
