The 2020 directory will be available in April, but you can access/update the 2019 version year-round.
Please be aware of solicitations requesting voluntary participation to list company information in a "free" business directory. Though these publications mention PMA and Fresh Summit, they are not affiliated with PMA:
If you sign an agreement, you could be locked into a non-terminable contract at a significant cost. We do not charge for our directory listings, and TriStar Publishing is the only approved vendor for this service.
While many reputable members of the trade press provide Fresh Summit editions, PMA’s Exhibitor Directory are the only official publications produced by PMA and distributed at Fresh Summit.
