There is no obligation on any company to do anything other than:

Corporate Reporting

Companies with more than $10 million in assets whose securities are held by more than 500 owners must file annual and other periodic reports. These reports are available to the public through the SEC's EDGAR database.

As to viable candidates (please note bolded):

Proxy Solicitations

The Securities Exchange Act also governs the disclosure in materials used to solicit shareholders' votes in annual or special meetings held for the election of directors and the approval of other corporate action. This information, contained in proxy materials, must be filed with the Commission in advance of any solicitation to ensure compliance with the disclosure rules. Solicitations, whether by management or shareholder groups, must disclose all important facts concerning the issues on which holders are asked to vote.
