Constellation Brands secures $300M delayed draw term loan for corporate flexibility

Constellation Brands has entered into a new term loan credit agreement worth up to $300 million with Manufacturers and Traders Trust Company and other lenders. The delayed draw facility, established on 18 September 2026, will be used for general corporate purposes, including potential debt repayment. The two-year term loans carry interest linked to Term SOFR or a base rate with rating-based margins. Unused commitments will incur a ticking fee beginning 30 days after closing. The agreement includes covenants that mirror the company's existing revolving credit facility. These impose limits on subsidiary indebtedness, liens, mergers, affiliate transactions, and sale-leasebacks, whilst requiring minimum interest coverage and maximum net leverage ratios. The structure is designed to reinforce Constellation Brands' financial flexibility and balance-sheet management.

M&T Bank beats Q2 revenue estimates by 1.9% as regional banks show mixed results

Regional banks delivered mixed second-quarter results, with revenues matching analyst expectations on average. M&T Bank reported revenues of $2.52 billion, up 4.9% year on year and exceeding consensus estimates by 1.9%. The bank also beat earnings per share projections and narrowly surpassed net interest income forecasts. Despite the strong quarter, M&T Bank's shares fell 1.3% following the announcement, trading at $238.67. The decline suggests investor expectations may have been higher than published Wall Street projections. Regional banks as a group have struggled, with share prices down an average of 1.5% since their latest earnings releases. These institutions face challenges including fintech competition, deposit outflows, credit deterioration, regulatory costs, and concerns about commercial real estate exposure following recent high-profile bank failures.
