Analysis · TDW · Energy & Transportation
Tidewater completed its $500 million acquisition of Wilson Sons Ultratug Participações and Atlantic Offshore Services, adding 22 platform supply vessels to its fleet. The deal was funded with $283.1 million in cash and $229.3 million in assumed debt. The filing reveals significant new financing obligations: Tidewater must replace BNDES parent company guarantees by December 31, 2026, backed by $170.5 million in DNB Bank letters of credit requiring 1.25x minimum liquidity coverage. The company also assumed guarantor status on a $22.5 million Banco do Brasil loan and will inherit $170.1 million in BNDES construction loans plus $36.7 million in conversion and drydock loans. This materially expands Tidewater's debt footprint and near-term liquidity commitments while adding scale in the Brazilian offshore support vessel market.
