Geopolitical conflict involving Iran; disruption of the Strait of Hormuz; volatility and sustained increases in oil and natural gas prices

Geopolitical instability in the Middle East, including the ongoing conflict involving Iran, as well as any actual or threatened disruption, closure, or restricted transit of the Strait of Hormuz, including the current closure, could adversely affect global oil and natural gas markets and materially impact our business, financial condition, results of operations and cash flows. The Strait of Hormuz is a critical transit chokepoint through which a significant portion of the world’s seaborne oil and natural gas supply flows, and recent military activity, attacks on shipping and threats of blockade in and around the Strait have contributed to sharp increases in crude oil and natural gas prices and heightened commodity price volatility. Future escalation of the Iran conflict, prolonged impairment or closure of the Strait of Hormuz, additional sanctions or export restrictions, or further attacks on oil and gas infrastructure or shipping lanes in the region could reduce global supply, drivesustained or extreme spikes in oil and natural gas prices, and increase uncertainty in the energy markets.

In addition, heightened geopolitical tensions related to the Iran conflict may result in new or expanded economic sanctions, export controls, tariffs or other governmental actions that could indirectly affect our customers, suppliers and financing sources, as well as broader macroeconomic conditions. These developments could impair our customers’ access to capital, increase their cost of capital or operating costs, or otherwise reduce their ability or willingness to fund exploration and production activity, which would negatively affect demand for our services.
