Emmaus Unit Sales (boxes shipped) - Q1 and Q2 2020 18 Q1 and Q2 2020 Summary Management Commentary Quarterly Emmaus Unit Sales are impacted by distributor inventory levels as well as the timing of bulk orders (i . e . , large - volume purchases) placed periodically by Emmaus’ distributors, which could reduce Emmaus Unit Sales in subsequent quarters in which no similar bulk orders occur A historically high level of bulk orders during Q 1 - 2020 adversely impacted Emmaus Unit Sales in Q 2 - 2020 Distributor inventories, at new highs in Q 1 - 2020 , as of July 31 , 2020 are now 32 % lower compared to March 31 , 2020 The factors above could continue and possibly impact Q 3 and Q 4 - 2020 as the COVID - 19 pandemic continues (potentially impacting doctor and pharmacy availability) and distributors/wholesalers may decide to carry lower than normal inventory levels (days sales ratios) Boxes sold by Emmaus to its Distributor and Specialty Pharmacy customers (Emmaus Unit Sales) declined from 7 , 456 in Q 1 - 2020 to 4 , 864 in Q 2 - 2020 However, Distributor Unit Sales growth remained strong in Q 2 - 2020 and increased 7 % over Q 1 - 2020 in the U .
