Physical Risks

Physical Risks are a category of climate risk referring to the direct, tangible damages to a company's assets and operations caused by climate change and extreme weather events. Forget abstract financial models for a moment; this is about the real, physical world intruding on the balance sheet. Think of a hurricane obliterating a coastal factory, a wildfire incinerating a timber company's forests, or a prolonged drought crippling an agricultural business. These risks can be sudden and violent (acute) or a slow, creeping threat (chronic), but their impact is always concrete. For the value investor, understanding physical risks is non-negotiable. They can permanently impair a company's earning power, destroy shareholder value, and turn a seemingly cheap stock into an expensive lesson. Assessing these threats is a crucial part of calculating a company's true intrinsic value and ensuring your margin of safety is built on solid ground, not sinking land.

Physical risks aren't a single, uniform threat. They manifest in two distinct ways, each requiring a different lens for analysis.

Acute risks are the ones that make headlines. They are event-driven, severe, and often unpredictable in their exact timing, though their frequency and intensity are increasing.

• What they are: These are extreme weather events like hurricanes, floods, wildfires, and severe heatwaves.
• How they impact business: The damage is immediate and often catastrophic. A flood can shut down a factory for months, destroying inventory and equipment. A wildfire can wipe out critical infrastructure. A cyclone can cripple a port, snarling a company’s entire supply chain. The result is lost revenue, massive, unplanned capital expenditures for rebuilding, and potentially a permanent loss of market share if customers are forced to go elsewhere.

Chronic risks are more insidious. They are the long-term, gradual shifts in our climate that relentlessly wear away at a company's business model and asset base.

• What they are: These include rising sea levels, long-term shifts in precipitation patterns, chronic water scarcity, and rising average temperatures.
• How they impact business: The effects are cumulative. A coastal real estate company might find its properties are becoming uninsurable as sea levels rise. A farming conglomerate may see its crop yields steadily decline due to persistent drought in a key region. A ski resort operator faces an existential threat from shorter winters and less snowfall. These slow-moving changes can degrade the long-term earning power of an asset until it becomes worthless.

Ignoring physical risks is like buying a house in a floodplain without checking the flood maps. It's a failure of due diligence that would make Benjamin Graham shudder. These risks strike at the very heart of a company's financial health and long-term viability.

A company's value is derived from its ability to generate cash over time. Physical risks directly attack this ability.

• Earnings and Cash Flow: Business interruptions from acute events directly reduce sales and earnings. Chronic risks, like water scarcity, can permanently increase operating costs (e.g., paying more for water), shrinking profit margins and depressing free cash flow.
• Assets and Book Value: When a factory is damaged or land becomes unproductive, its value must be written down on the balance sheet. This directly erodes a company's book value. Furthermore, companies facing high physical risks may have to spend enormous amounts of cash on adaptation (e.g., building sea walls, relocating facilities), diverting capital that could have been used for growth or returned to shareholders.

A savvy investor digs deeper to uncover these potential landmines. Here’s how you can start spotting them:

• Read the Fine Print: Scour a company's annual report (like the 10-K in the U.S.), specifically the 'Risk Factors' section. Companies are increasingly required to disclose their exposure to climate-related risks.
• Play Geographer: Investigate where a company's most critical assets are. A company with all its manufacturing plants concentrated in a hurricane-prone region has a significant concentration risk that might not be obvious from its consolidated financial statements.
• Follow the Supply Chain: A company might be safely located inland, but if its single most important supplier is based in a flood-prone area in another country, its operations are still highly vulnerable.
• Check the Insurance Bill: Rising insurance premiums or, even worse, the inability for a company to get insurance for certain key assets, is a massive red flag. It’s a signal from the insurance market that the risks are becoming unmanageable and potentially unpriced by stock market investors.
