| Item 3. | Source and Amount of Funds or Other Consideration |
The Common Stock was acquired with approximately $8.9 million of working capital set aside by TCP and TCPI for the general purpose of investing. TCP and TCPI maintain commingled margin accounts with various financial institutions, which may extend margin credit to TCP and TCPI as and when required, to open or carry positions in the margin accounts, subject to applicable federal margin regulations, stock exchange rules and credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the accounts. The margin accounts may from time to time have debit balances. Since multiple different securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Common Stock reported herein. | |

The Reporting Persons are filing this Statement as an amendment to their Schedule 13G previously filed on July 22, 2024. The Reporting Persons purchased the Common Stock reported hereunder for investment purposes, and such purchases were made in the Reporting Persons' ordinary course of business.

The Reporting Persons may engage in discussions with the Issuer and its representatives and/or other stockholders, seek to enter into a confidentiality agreement with the Issuer and/or discuss with the Issuer different strategic alternatives or changes to the Issuer's operations. There can be no certainty as to whether discussions with the Issuer will occur, the outcome of any such discussions or whether the Reporting Persons will take any actions relating to the Issuer.
Subject to applicable law and regulation, the Reporting Persons may modify their ownership of the Common Stock, including acquiring additional Common Stock or disposing of some or all of the Common Stock beneficially owned by them. Such actions may be based on the Reporting Persons' assessment of the Issuer's operations and prospects, prevailing market conditions or other investment considerations. | |
