Mastek Limited - Midsize IT company

A few queries

  1. I read somewhere 80% of Mastek revenues come from Digital. Is it true? If yes why is this stock so cheap when at 22x FY22E when Happiest Minds is at 101x FY22E?
  2. The backlog is up 40% YoY so does that mean this company can grow dollar revenue 25% plus in FY22?
  3. Other IT companies give guidance. Why doesnt Mastek give guidance or does it?
