We delivered record first quarter results across nearly all of our key operating metrics including total revenues , gross profit , operating profit , adjusted EBITDA¹ and operating cash flow . This success was largely driven by the continued positive reception of our single family residential products , allowing for additional market share gains . Furthermore , our vertically integrated architectural glass platform and prior automation investments continue to deliver significant structural advantages amid tight labor and material availability impacting our industry . We are optimally positioned to efficiently control our supply chain , manufacture products with shorter lead times and best serve customers in what we expect to be a year of significant growth in demand . Moving forward , we remain confident in our ability to maintain our industry leading margins and gain additional share in the quarters ahead . " Christian Daes , Chief Operating Officer of Tecnoglass , added , “ In the first quarter , we were thrilled to see the positive momentum continue in our business as we reported a sharp acceleration of growth . Encouraging trends in housing starts and de - urbanization combined with our efforts to expand our customer relationships are all supporting the growth of our single - family residential revenue , which increased over 70 % year - over - year . Additionally , we are pleased to see our large scale projects resuming activity , in line with improving fundamentals and the ABI index climbing higher into expansion territory for the second consecutive month in March . Looking ahead , our momentum has continued into April and May as new business wins and record levels of backlog leave us well positioned for further value creation . "
