Oceaneering International, Inc. (NYSE: OII), headquartered in Houston, Texas, is an offshore-oil-and-gas-and-subsea + defense + emerging-Mobile-Robotics + emerging-Aerospace-and-Defense subsea-robotics-and-services leader providing distinctive multi-cycle Oceaneering Subsea-Services + Subsea-Robotics-Manufactured-Products + Subsea-Projects + Integrity-Management + Aerospace-and-Defense-Technologies services to global-Offshore-E&P + US-DoD + emerging-Mobile-Robotics customer base. Distinctive multi-cycle Oceaneering-International-and-Mike-Hughes-and-Lad-Handelman heritage: founded 1964 in Long-Beach-CA by Mike Hughes + Lad Handelman + multi-cycle-Oceaneering-entrepreneurs; 1975 NASDAQ Oceaneering-IPO; 1979 NYSE Oceaneering-listing; multi-cycle 1979-2017 multi-cycle Oceaneering + multi-cycle-disciplined-bolt-on-M&A; 2017 Rod Larson CEO appointment. Multi-decade strategic-evolution: 1964-1975 Mike-Hughes-and-Lad-Handelman-Oceaneering-Long-Beach-CA platform; 1975 NASDAQ Oceaneering-IPO; 1979 NYSE-listing; 1979-2017 multi-cycle Oceaneering + multi-cycle-disciplined-bolt-on-M&A; 2017 Rod Larson CEO; 2014-2020 substantial multi-cycle offshore-oil-and-gas-downcycle + multi-cycle-Oceaneering-restructuring; 2020-2025 substantial multi-cycle post-COVID + emerging-offshore-oil-and-gas-recovery + emerging-Aerospace-and-Defense + emerging-Mobile-Robotics. Under CEO Rod Larson (since 2017, ~8+ year longtime Cameron-International executive), FY2025 closes with selected various aggregate revenue ~$2.65-3.05B, adj. EBITDA ~$330-440M, adj. EPS ~$1.40-2.10, net debt ~$0.4-0.7B, and ~100-105M shares outstanding.
