Beam could be fined $2200 for every scooter it fails to remove from Canberra's streets by 4pm on Friday next week.
It's emerged Beam had 250 secret scooters hidden from the ACT government on top of the 950 it was licensed to operate, making a total of 1200 - all adding up to a potential maximum fine of $2.6 million.
On top of that, the ACT government said any scooters which remained would be impounded and a fee of $154.20 per device charged.
The ACT government said it was working with Beam to clear Canberra streets of the purple mode of transport.
"Our focus will be working with Beam to have the devices removed promptly and safely," a spokesperson said.
Beam said it would remove its scooters and put them in its warehouse, though it wouldn't disclose where that was.
It runs its scooters in around 30 Australian towns and cities, as well as in South Korea, Thailand, Turkey, Japan, Indonesia and Malaysia, so the Canberra scooters may just be deployed rather than destroyed.
"Beam's operations in Canberra will continue until 11.59pm on Sunday 8 September, following which they will be removed from the streets of Canberra over the following week," Beam said.
The company also said it was refunding customers, saying: "Beam has already contacted riders with ride subscriptions that will be impacted by the closure regarding any applicable refunds."
As Beam departs, the ACT government has been talking to its rival, Neuron, to see if its fleet can be expanded.
The company has been given a three-month extension to its licence. The ACT government was not expecting any price rise during that period.
Other operators may emerge, a government spokesperson said: "We will be working closely with any providers engaged in Canberra through the upcoming market sounding process to ensure e-scooters remain a viable option for commuting."
Meanwhile, more has emerged from Auckland about how the Beam deception operated - Auckland Council does believe it was deception and not a mistake.
Cities use a system called Ride Report which tracks e-scooters and sends the information to the city authorities.
Auckland Council said the data had been manipulated by Beam.
"The evidence suggests that these anomalies were intentional," a statement said.
"It appears that data provided to Ride Report from Beam regularly showed a high number of vehicles operating in an 'unknown' state, which is intended to indicate connectivity loss, GPS issues, missing vehicles, or other operational variances."
Beam earlier said there had been no intention to defraud the taxpayer by understating the number of its scooters.
"We emphatically reject any suggestion that this was a scheme to deprive councils of revenue," Beam's chief executive Alan Jiang said in an earlier statement.
It was, he said, a mistake and the company was "deeply apologetic".
