Description
MarineMax, Inc., a leading recreational boat, yacht, and superyacht services company, reported a cybersecurity incident to the U.S. Securities and Exchange Commission (SEC) on March 10, 2024. The company disclosed that an unauthorized third party gained access to portions of its information environment, with the incident beginning on Sunday, March 10, 2024, or earlier. Upon detection, MarineMax activated its pre-established incident response and business continuity protocols, implementing immediate containment measures. These actions caused disruptions to a segment of the company’s business operations, though MarineMax emphasized that its overall activities continued "in all material respects" despite the breach. The company engaged external cybersecurity experts to investigate the incident’s scope and origins and formally notified law enforcement authorities. MarineMax did not confirm whether the incident involved ransomware or other specific attack vectors in its public filings or responses to media inquiries.
The SEC filing stated the investigation remained ongoing as of March 10, with no determination yet on whether the incident would materially affect MarineMax’s financial condition or operational results. The company asserted that the compromised information environment did not contain sensitive data, though it did not elaborate on the nature of the accessed systems or data types. MarineMax reported $2.39 billion in revenue for 2023, its highest annual revenue to date, but provided no indication that the cyberattack directly impacted its financial performance at the time of disclosure. The incident occurred against a backdrop of heightened cyber threats targeting the marine industry, including a June 2023 attack on Brunswick Corporation that disrupted production and incurred over $85 million in costs, and a 2023 ransomware incident affecting a German military vessel and luxury yacht manufacturer. MarineMax’s disclosure adhered to SEC requirements for material cybersecurity incidents but avoided speculative assessments of long-term operational or reputational consequences.
