That is not a borrowing. It is an increase in availability of a credit facility. It is an indication that the lender sees increased creditworthiness of the borrower.
In a hyper-growth company, certainly cash is needed to fund that growth.
A combination of an increase in a credit facility AVAILABLE IF NEEDED, and a modest equity capital raise using miniscule dilution of less than 5%. Sounds to me like the capital structure and balance sheet are being very professionally and effectively managed.
