This is a question regarding Subjunctives, So a singular form disclose is needed

[esledge]

The bossy main verb "require" must be followed by a noun phrase beginning with "that." Within the "that" phrase, we need a subject ("public company") and a command subjunctive ("disclose"--the infinitive "to disclose" minus the "to").

Note that the verb within the "that" phrase is NOT determined by subject-verb agreement rules.
