LeEco, a Chinese company that made a big splash in the U.S. last fall, is preparing for a round of layoffs that may happen as soon as Tuesday, according to sources.

Two people told CNBC the company is planning massive layoffs in the U.S., with one source saying that only 60 employees will be left after the cut. The company's current headcount in the U.S. is over 500, according to this person.

CNBC obtained an email calling employees together for a Town Hall Meeting that will occur in three of the company's U.S. locations, including San Diego, Santa Monica and San Jose, at 10 a.m. PST. The email asks employees to attend unless they're off for the day, in which case they're asked to call in.

It's not clear what will be announced at the meeting, but a second source told CNBC that layoffs will be announced tomorrow.
