Since its initial public offering in April, Indonesia's GoTo Group has lost more than half of its initial value.
GoTo shares sold off after pre-IPO shareholders decided not to take part in a secondary offering after the lock-up expired.
The GoTo Group is made up of two of Indonesia's largest tech companies. The lock-up period was agreed to by SoftBank and other early investors.
GoTo said in October that it was working with pre-IPO shareholders to explore a coordinated secondary offering of their shares before the lock-up expired.
That didn't work out. Pre-IPO shareholders decided not to proceed with the secondary offering on the last day of the lock-up.
On Thursday, the stock fell to 141 rupiah and continued to fall on Monday. The company has a valuation of about 126 trillion rupiah.
The valuations of other Southeast Asian tech companies have fallen. Since listing in the U.S., competitor Grab has lost a lot of its value. Since its Jakarta IPO, the company's initial valuation has fallen by 70%.
In November, GoTo Group reported it had accumulated losses of 20.32 trillion rupiah, up from a year ago's accumulated losses of 11.86 trillion rupiah.
The group will be laying off 12% of its workforce, or around 3000 jobs.
