Mueller Water Products Inc

(a) In December 2023, we obtained a waiver under our ABL (“ABL Waiver”) to provide for additional time associated with certain technical reporting requirements that were delayed as a result of the cybersecurity incident announced on October 28, 2023. Under the ABL Waiver, the maximum aggregate amount of borrowings and other credit extensions under the ABL was limited to $50.0 million at any time outstanding until all of the required reports were delivered. During our first fiscal quarter of 2024, we delivered the required reports and on February 6, 2024, the ABL Waiver was terminated. Accordingly, we are no longer subject to any additional restrictions or borrowing limitations under the ABL including the $50.0 million temporary limit on credit extensions.

(c)No officers or directors, as defined in Rule 16a-1(f), adopted, modified or terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement,” as defined in Regulation S-K Item 408, during the first quarter of fiscal 2024.
