On December 10, 2020, A.M. Castle & Co. entered into an Amendment No. 3 to its Revolving Credit and Security Agreement (the “Credit Agreement Amendment”) by and among the Company, the other borrowers and guarantors party thereto and PNC Bank, National Association as the agent and the lenders, which amends that certain Revolving Credit and Security Agreement dated as of August 31, 2017 (as amended to date, and as further amended by the Credit Agreement Amendment, the “Expanded Credit Facility”) to provide for additional borrowing capacity. The Expanded Credit Facility provides for an additional $25.0 million Revolving B (Priority) credit facility (the “Revolving B (Priority) Credit Facility”) made available by certain of the company’s shareholders, which will be subordinated to the $125.0 million senior secured, revolving credit facility (the “Revolving A Credit Facility”) and senior to the $21.5 million senior secured, revolving credit facility (the “Revolving B Credit Facility”). The Revolving B (Priority) Credit Facility will bear interest at 15.0% per annum, which will be paid-in-kind unless the Company satisfies the conditions specified in the Expanded Credit Facility and elects to pay such interest in cash. As part of the Credit Agreement Amendment, the Company and PNC also agreed to extend the maturity of the Credit Agreement to February 28, 2023, and to amend the Credit Agreement to (i) reduce the available borrowing capacity under its Revolving B Credit Facility from $25.0 million to $21.5 million and subordinate the payment under the Revolving B Credit Facility to the Revolving B (Priority) Credit Facility, (ii) increase access to available borrowings by reducing the liquidity covenant test threshold from $12.5 million to $8.75 million, and (iii) increase the interest applicable to the Revolving Credit A Facility to LIBOR-base rate plus a margin of 4.0%. The Expanded Credit Facility continues to be secured by substantially all personal property assets of the Company and its domestic subsidiary guarantors.
