Paltry quarterly from Todos to win things up.

This at the end of the 10-Q explains some of it:

During the first quarter of 2021, the Company’s contractual agreement to supply Covid-19 testing kits to a significant customer expired. At the customer’s request, the Company continued to supply Covid-19 testing kits until such time as the customer requested that the Company stop doing so. The customer has not yet paid for some of the Covid-19 testing kits so supplied, and has not yet renewed its agreement with the Company. The Company believes that ultimately the customer will pay for the Covid-19 testing kits so supplied and will renew its agreement to purchase Covid-19 testing kits from the Company. Should the customer not renew its agreement to purchase Covid-19 testing kits from the Company, it could have a material adverse effect on the Company’s revenues from the sale of Covid-19 testing kits.
