On a resume, how do you label a company that has since been acquired?

[papaya]

Do I say Company ABC (now Company CBA), or Company ABC (acquired by Company CBA), or another way? What's the standard way of wording this?

[Maggie]

Company ABC (now company CBA). No need to explain the hows or whys unless your interviewer asks.

[Zeebarista]

Company ABC (now Company XYZ) - that's the easiest way. If the interviewer is curious, they will ask.

[Judy]

No real standard wording - either of your examples is fine.
