AMBUb.CO to "buy" from "hold" as it expects improved 2023
revenues and a likely hike to the group's full-year guidance

market expectations we expect it to return to double-digit
top-line growth this year," the brokerage says

saying the new management seems to be operating with an
"under-promise and over-achieve" mentality

"strong buy" or "buy", three "hold" and three "sell"
** Shares in Ambu rise 7% in morning trade, among the top
