Company acquired by another company h1b stamping

[f1h1bi140]

Hi All,

My employer A is acquired by another company B.
My employer said that there is no need for H1B amendment.

I am planning to travel to India end of April 2017. It will be helpful if anyone traveled to India in a similar situation.

Should I mention the new companies name or the old companies name on DS-160(My I797 and LCA still have Company A's name.)
I have got stamped twice on H1B(Once in India and once in Canada) with company X(Not Company A). This will be my 3rd H1b stamping.

Thanks and Regards,
SM
