José Manuel Daes , Chief Executive Officer of Tecnoglass , commented , “ I am thrilled to announce our most profitable quarter on record , building on our team's outstanding performance which again drove record results in nearly all financial metrics . During the quarter , we were able to drive substantial operating leverage while expanding our mix of single - family residential sales in the U.S. , resulting in another quarter of record revenues , margin expansion , and our 5th straight quarter of significant cash flow generation . Our strategically located , vertically integrated and low cost operations have provided us with sustainable competitive advantages that truly differentiate Tecnoglass in the tight supply environment that our industry is experiencing . We are winning new business and strengthening our existing customer relationships because we are able to supply superior quality products with short lead times at an attractive value , which is undoubtedly advancing our reputation as a global leader in both architectural glass innovation and service . Moving forward , we will continue to execute our proven strategy to capture elevated demand in the U.S. , while approaching capital allocation with a returns oriented mindset . Our strong balance sheet , very low leverage profile and ample capital resources squarely position us to do so as we plan to further invest in operational enhancements . The future remains extremely bright for Tecnoglass and we are firmly situated to deliver another year of record results in 2021. ” Christian Daes , Chief Operating Officer of Tecnoglass , added , “ Our ability to timely deliver best - in - class products led to outsized revenue growth and market share gains in the U.S. during the second quarter . Revenues in single - family residential increased by almost 160 % year - over - year and nearly doubled compared to the second quarter of 2019. This accomplishment is a testament to the market leading platform we have created and we could not be more pleased with our progress since we entered the single - family residential business four years ago . This attractive category now represents 34 % of our total revenues compared to 19 % in the prior year period . Additionally , we ended the second quarter with a record backlog across our growing footprint as large scale commercial projects continue to resume construction activity . Looking to the remainder of 2021 , we are pleased with our positioning and continue to expect strength in residential demand to drive the majority of our growth . "
