To my knowledge, there is no such thing as a "return on profitability per employee." So for me the initial sentence must be in the plural, i.e. the correct version should be "return [...] and profitability [...] are"
You can also spot another error here, since they "conclude that the return and profitability are indistinguishable from those that were not privatized." This should be "the return and profitability are indistinguishable from those of companies that were not privatized at all." In the original sentence, we're matching "return and profitability" with "companies," which doesn't work.
The original sentence is correct.
Skeleton of the sentence -
1.1) Jie Gan of Cheung Kong Graduate School of Business,
1.2) Yan Guo of Peking University and
1.3) Chenggang Xu of the University of Hong Kong
conclude that
2.1)
the return on assets and profitability per employee for companies [that have undergone partial share offerings]
2.2.1-COMPARISON) IS indistinguishable from
2.2) those that were not privatised at all.
"is indistinguishable from" is correct in this case because of THE in 2.1)
If there is no "THE" in (2.1), then "are indistinguishable from" is correct.
Btw - the source of this sentence -
