Material Changes and Agreements

- Amendment No. 4 to Purchase Agreement: This amendment narrowed the scope of the original acquisition agreement. While the initial agreement included Aquarion Water Company of Massachusetts, Inc.

Outlook, Risks, and Contingencies
Management Commentary and Outlook: The transaction expands Unitil's water utility operations. The company has secured financing to support the acquisition and general corporate purposes. The transition services agreement ensures operational continuity for up to five years post-closing.
Risks and Contingencies:
- Covenant Compliance: Unitil must maintain a Funded Debt to Capitalization ratio below 65%. Failure to meet this or other covenants could trigger an event of default.
- Events of Default: The Credit Agreement lists standard defaults including failure to pay, cross-defaults, change of control, and judgments exceeding $25 million. Default could result in the acceleration of all obligations.
- Prepayment Obligations: Unitil is required to prepay the Credit Agreement from net proceeds of certain debt/equity issuances, asset sales (above a $25 million threshold), and indemnification proceeds related to the acquisitions.
Investor Verification Checklist
- Verify the final purchase price adjustments, specifically the reconciliation of the $0.6 million working capital and reimbursable capital expenditure estimate.
- Confirm the current Funded Debt to Capitalization ratio to ensure compliance with the 65% covenant threshold following the $42.7 million drawdown.
- Review the terms of the Operating and Transition Services Agreement to understand the duration and cost implications of the 5% margin on transition services.
- Monitor the status of the excluded AWC-MA asset to determine if future acquisition opportunities or competitive dynamics arise.
- Assess the impact of the new debt maturity (June 30, 2027) on the company's liquidity profile and refinancing needs.
