What happens if I fail to comply with MAR?

There would normally be no immediate consequences. NCAs do not perform constant controls on all companies regulated under MAR but would rather act upon specific decisions of an NCA. In case of an investigation, the NCA would most likely detect any inadequacies and, as a result, evaluate the extent of the violation and decide on appropriate sanctions to impose. Notably also, the NCAs and ESMA have developed an advanced cross-border technical cooperation standard for sanctions and measures.

MAR regulates not only which infringements are subject to certain sanctions, but also elaborates on which sanctions may be imposed upon the regulated company itself as well as upon natural persons on a case by case basis.
