Tidewater Inc. (NYSE: TDW), headquartered in Houston, Texas (corporate HQ) with substantial multi-cycle Singapore + Norway + Dubai + Brazil + Aberdeen + multi-jurisdiction operational presence across ~30+ countries, is a global offshore support-vessel (OSV) operator + emerging-offshore-oil-and-gas + emerging-offshore-wind operator providing distinctive multi-cycle global OSV-and-chartering services to oil-major + national-oil-company + emerging-offshore-wind + emerging-multi-cycle-multi-jurisdiction-emerging-offshore-customer base globally. The company has a distinctive multi-decade Tidewater-and-Gulf-of-Mexico-OSV heritage: founded 1955 in New Orleans, Louisiana as Tidewater Marine (originally serving Gulf-of-Mexico offshore-oil-and-gas + emerging-OSV + emerging-deepwater); multi-cycle global expansion through 1970s-2010s; 2017 Chapter 11 bankruptcy (post-2015-2016 oil-cycle-stress); 2017-2018 post-bankruptcy emergence; 2018-2019 Gulfmark Offshore merger; 2023 Solstad Offshore acquisition (Norwegian-OSV-and-subsea operator providing multi-cycle Solstad-North-Sea-and-Norwegian-OSV-and-subsea-emerging-offshore-wind integration); 2020-2025 post-COVID + post-2022-Russia-and-Ukraine + emerging-offshore-oil-and-gas + emerging-offshore-wind cycle. Under CEO Quintin Kneen (since 2019, prior longtime Tidewater + Gulfmark Offshore + multi-cycle offshore-shipping executive), FY2025 closes with selected various aggregate revenue ~$1.40-1.55B, adj. EBITDA ~$640-740M, adj. EPS ~$5.50-7.50, ~$0.6-0.9B net debt, and ~52M shares outstanding. The first deep-dive — global offshore support-vessel + emerging-offshore-wind franchise — covers entire OSV-and-offshore-support-and-emerging-offshore-wind business + distinctive multi-cycle global-OSV-and-emerging-offshore-wind positioning. Fleet composition: ~200+ OSV fleet across PSV (~100+ vessels providing deepwater-and-ultra-deepwater supply), AHTS (~50+ vessels providing anchor-handling + towing), Crew Boats + MPV (~50+ vessels). Modern + IMO-and-MEPC-and-CII-and-EEXI-and-environmental-compliance + Solstad-Norwegian-OSV-and-North-Sea fleet. Service-area: West Africa (substantial Nigeria + Angola + Equatorial Guinea + Mauritania + Senegal + Ghana + Côte d'Ivoire emerging-deepwater), Middle East (Saudi Arabia + UAE + Qatar + Oman + Egypt + multi-jurisdiction Middle-East offshore-oil-and-gas), Americas (Gulf-of-Mexico + Brazil + Mexico + Guyana + Suriname + Americas-deepwater), Asia-Pacific (Australia + Indonesia + Malaysia + Thailand + Vietnam), North Sea + Europe (Solstad-acquired Norway + UK-and-Aberdeen + Netherlands + emerging-offshore-wind-and-North-Sea). Customer base: oil-major (Shell + ExxonMobil + Chevron + BP + TotalEnergies + Eni + Equinor + Petrobras + Saudi Aramco + Lukoil), national-oil-company (Petrobras + Saudi Aramco + ADNOC + Pemex), emerging-offshore-wind (Ørsted + RWE + Vattenfall + Iberdrola + EDF), refining-and-petrochemical. Emerging structural-tailwinds: emerging-multi-cycle global offshore-oil-and-gas capex-cycle providing OSV-day-rate-and-utilization-and-charter-rate-and-tonnage-tightness tailwinds + emerging-deepwater-and-ultra-deepwater + emerging-Africa-and-Middle-East-and-Brazil-and-Mexico-and-Guyana + emerging-Asia-Pacific + emerging-North-Sea + emerging-offshore-wind + emerging-OSV-tonnage-supply-tightness. Competes with Edison Chouest (private US-largest-OSV most-direct-larger-comp), Bourbon Offshore (BOURBON-PA), Vroon Offshore (private), Maersk Supply Service (Maersk-subsidiary), DOF (DOF-NO most-direct-Norwegian-OSV-comp), Solstad Offshore (now-Tidewater-acquired), Siem Offshore (SIOFF-NO), Havila Shipping (HAVI-NO), Eidesvik Offshore (EIOF-NO), SEACOR Marine (SMHI most-direct-mid-cap-US-comp), Hornbeck Offshore (private); subsea Subsea7 (SUBC-NO), Saipem (SPM-MI), TechnipFMC (FTI); emerging-offshore-wind-OSV Cadeler (CDLR-NO most-direct-emerging-offshore-wind-comp), Eneti. The second deep-dive — post-bankruptcy + Solstad-acquisition + multi-decade-OSV-cycle compounder thesis — covers post-2017-bankruptcy-and-2018-Gulfmark-merger-and-2023-Solstad-acquisition transformational-platform, multi-decade OSV-cycle, emerging-deepwater-and-emerging-offshore-wind, emerging-OSV-tonnage-supply-tightness tailwinds, Quintin Kneen + Tidewater-and-Gulfmark-and-offshore-shipping expertise. Multi-decade compounder thesis combines Tidewater-and-Gulf-of-Mexico-OSV ~70 year heritage, post-bankruptcy + Solstad-acquisition transformational-platform, ~200+ OSV fleet ~15-20% global market-share, multi-decade OSV-cycle + emerging-deepwater-and-offshore-wind + OSV-tonnage-supply-tightness structural-tailwinds, Quintin Kneen expertise, multi-cycle-deleveraging + IG-equivalent balance-sheet. Capital position is post-bankruptcy-restructured BB+/BB-equivalent, capital-deployment-and-deleveraging-focused, conservative: net debt ~$0.6-0.9B (~1.0-1.4x leverage post-2023-Solstad-acquisition deleveraging), $0.2-0.4B cash + undrawn revolver liquidity, FCF ~$300-450M/yr deployed into deleveraging-and-fleet-renewal + ~$50-150M/yr buyback + capex $100-200M/yr, no-regular-dividend, ~52M shares. At ~$55-90 per share, equity value ~$2.9-4.7B, EV ~$3.5-5.6B, ~7-16x EPS and ~5-8x EV/EBITDA. Base case: OSV-cycle constructive + Solstad-integration delivers-synergy + emerging-offshore-wind demand + revenue $1.50-1.70B + EBITDA $720-840M + EPS $6.00-8.50 + buyback + ~5-25% return. Bull case: OSV-cycle accelerates + Solstad substantial-synergy + offshore-wind + deepwater-and-Africa-and-Brazil-and-Guyana inflects + tonnage-tightness + revenue $1.70-2.00B + EBITDA $850-1100M + EPS $8.50-12.00 + substantial-buyback + re-rate 10-15x + 30-70%+ return. Bear case: OSV-cycle-rolls + deepwater-and-offshore-wind disappoints + EPS $3.00-4.50 + de-rate 5-8x + flat-to-substantially-negative.
