Operator Ladies and gentlemen, thank you for standing by, and welcome to the Harmony Biosciences first-quarter 2021 financial update call. [Operator instructions] I would now like to hand the conference over to your host today, Lisa Caperelli, investor relations. Please go ahead. Lisa Caperelli -- Investor Relations Thank you, operator. Good morning, everyone and thank you for joining us today as we review Harmony Biosciences first-quarter 2021 financial performance and provide business updates. Before we begin, I encourage everyone to go to the Investors section of the Harmony Biosciences website to find the press release and slides that accompany our presentation today, including a reconciliation of the GAAP to non-GAAP financial measures. At this stage of our company life cycle, we believe non-GAAP financial results better represent the underlying economics of our business.
