Lumen Technologies, Inc.

As of June 30, 2025, we were exposed to market risk from changes in interest rates on our variable rate long-term debt obligations and fluctuations in certain foreign currencies.

Our management periodically reviews our exposure to interest rate fluctuations and periodically implements strategies to manage the exposure. From time to time, we have used derivative instruments to swap our exposure to variable interest rates for fixed interest rates. We have established policies and procedures for risk assessment and the approval, reporting, and monitoring of derivative instrument activities. As of June 30, 2025, we did not hold or issue derivative financial instruments for trading or speculative purposes.

As of June 30, 2025, we had approximately $6.0 billion aggregate principal amount of debt bearing unhedged floating interest rates based on the secured overnight financing rate ("SOFR"). A hypothetical increase of 100 basis points in SOFR relating to our $6.0 billion of unhedged floating rate debt would, among other things, decrease our annual pre-tax earnings by approximately $60 million.

We conduct a small portion of our business in currencies other than the U.S. dollar, the currency in which our consolidated financial statements are reported. Although we continue to evaluate strategies to mitigate risks related to the effect of fluctuations in currency exchange rates, we will likely continue to recognize gains or losses from international transactions. Accordingly, changes in foreign currency rates relative to the U.S. dollar could positively or negatively impact our operating results.

Certain shortcomings are inherent in the method of analysis presented in the computation of exposures to market risks. Actual values may differ materially from those disclosed by us from time to time if market conditions vary from the assumptions used in the analyses performed. These analyses only incorporate the risk exposures that existed at June 30, 2025.
