If the Office of the Secretary of State determines that one or more grounds exist under § 47-1A-1530 for revocation of a certificate of authority, the Office of the Secretary of State shall serve the foreign corporation with written notice of that determination under § 47-1A-1510. If the foreign corporation does not correct each ground for revocation or demonstrate to the reasonable satisfaction of the Office of the Secretary of State that each ground determined by the Office of the Secretary of State does not exist within sixty days after service of the notice is perfected under § 47-1A-1510, the Office of the Secretary of State may revoke the foreign corporation's certificate of authority by signing a certificate of revocation that recites the ground or grounds for revocation and its effective date. The Office of the Secretary of State shall file the original of the certificate and serve a copy on the foreign corporation under § 47-1A-1510.
The authority of a foreign corporation to transact business in this state ceases on the date shown on the certificate revoking its certificate of authority.
