An issuance under paragraph (2)(ii) of this subsection shall conform to §§ 6–102 and 6–103 of this subtitle. Prior authorization of the Commission is not required for an assumption or guarantee under paragraph (2)(i) of this subsection or an issuance under paragraph (2)(ii) of this subsection made by a gas company, electric company, or telephone company whose gross annual revenues, for the most recent calendar year for which data are available, are less than 3% of the total gross annual revenues of all public service companies in the State during the same calendar year, if the gas company, electric company, or telephone company: provides prior written notice to the Commission of the transaction; and obtains approval of the transaction from the entity in another state that regulates the gas company, electric company, or telephone company. Subject to the requirements of subsection (c) of this section, the Commission may authorize an act described under subsection (a)(2) of this section if the Commission finds that the act is consistent with the public convenience and necessity. Authorization under this subsection does not: revive a lapsed franchise, validate an invalid franchise, or add to the powers and privileges in a franchise; or waive a forfeiture. This subsection does not apply to the formation of a holding company by a public service company in a corporate reorganization that involves an exchange of stock of the public service company for stock in the holding company. In this subsection, a company controlling a public service company is deemed a public service company of the same class as the controlled public service company. Without prior authorization of the Commission, a public service company may not take, hold, or acquire any part of the capital stock of a public service company that: operates in Maryland; and is of the same class as the acquiring company. Except as provided in subparagraph (ii) of this paragraph, a stock corporation may not take, hold, or acquire more than 10% of the total capital stock of a public service company that operates in Maryland unless: the stock is acquired as collateral security; and the Commission approves the acquisition. The Commission may authorize a public service company of the same class to take, hold, or acquire more than 10% of the total capital stock of a public service company that operates in Maryland. A public service company may not be a party to a violation of this subsection. Notwithstanding paragraph (2) of this subsection, § 6–105 of this subtitle shall apply, and the provisions of this subsection do not apply, to the acquisition, ownership, or disposition of any capital stock or voting securities of a company that controls, directly or indirectly, a gas and electric company. Notwithstanding any other provision of this subsection, the Commission may authorize, in accordance with § 6–105 of this subtitle, the taking, holding, or acquiring of all or any part of the capital stock of a gas and electric company that operates in the State by a stock corporation or a public service company that is not of the same class as the gas and electric company.
