An earnings briefing in Hong Kong turned heated when the chief financial officer refused to continue with his presentation until an analyst from Macquarie Group Ltd. left the room.

In a video obtained by Bloomberg News, PAX Global Technology Ltd. CFO Chris Lee can be seen standing over a seated Timothy Lam and ordering him to leave the conference room on Wednesday. Lam initiated coverage on PAX Global's stock in April with an underweight rating, making him the only analyst out of 17 tracked by Bloomberg to have a bearish recommendation at the time. On Thursday, Lee said he regretted his behavior, calling it a "one-off" that didn't reflect the management's position and saying he welcomes "diverse points of view," according to an e-mailed statement.

The analyst was asked to leave because PAX Global disputes parts of his report, not because of the rating, Lee said by phone on Wednesday. Lam wasn't invited to the briefing, Lee said. Macquarie spokeswoman Ida Cheung declined to comment. All analysts should be able to attend the briefing, regardless of their view on the company, Macquarie's Lam wrote in a note, in which he maintained his underweight rating and raised his target price by 10 H.K. cents.
