Is HTX part of MHA?

Excuse me, could you clarify for me if HTX is indeed a part of the MHA organization? I've been doing some research and I'm a bit confused about the affiliation between the two. If HTX is indeed affiliated with MHA, could you provide some insight into the nature of their relationship? Are they partners, subsidiaries, or simply collaborating in some way? I'd appreciate any clarification you can offer on this matter.
