It is not possible to predict or identify all such risks. There may be additional risks that we consider immaterial or which are unknown. These factors include, but are not limited to, the following:

• COVID-19 has had, and will continue to have, a materially adverse impact on our financial condition and operations, which impacts our ability to obtain acceptable financing to fund any resulting shortfalls in cash from operations. The current, and uncertain future, impact of theCOVID-19 outbreak, including its effect on the ability or desire of people to travel (including on cruises), will continue to impact our results, operations, outlooks, plans, goals, growth, reputation, cash flows, liquidity, and stock price

• World events impacting the ability or desire of people to travel may lead to a decline in demand for cruises

• Incidents concerning our ships, guests or the cruise vacation industry as well as adverse weather conditions and other natural disasters may impact the satisfaction of our guests and crew and lead to reputational damage

• Changes in andnon-compliance with laws and regulations under which we operate, such as those relating to health, environment, safety and security, data privacy and protection, anti-corruption, economic sanctions, trade protection and tax may lead to litigation, enforcement actions, fines, penalties, and reputational damage

• Increases in fuel prices, changes in the types of fuel consumed and availability of fuel supply may adversely impact our scheduled itineraries and costs

• Fluctuations in foreign currency exchange rates may adversely impact our financial results

• Overcapacity and competition in the cruise and land-based vacation industry may lead to a decline in our cruise sales, pricing and destination options

• Geographic regions in which we try to expand our business may be slow to develop or ultimately not develop how we expect

• Inability to implement our shipbuilding programs and ship repairs, maintenance and refurbishments may adversely impact our business operations and the satisfaction of our guests
