Can I ask a question re this comment

"I note also that PEA's margins are holding up well despite the increased competition on BOO contracts from ZEN, who's revenue and market share gains have been made on the back of margins approximately half of PEA's."

If ZEN grows on half margins to PEA, does this mean ZEN offers a better BOO price to buyers or does it mean for the same sell price that PEA makes double margin. One way says ZEN is more efficient and the other way says PEA is more efficient.

I wonder which it is!
