Caterpillar Financial Services Corporation (Cat Financial) is closing the
Cat Financial PowerInvestment Notes program on September 15, 2025

PowerInvestment Notes (both Retail Tier and Corporate Tier) will yield 0.00% interest and no new investments will be accepted after August 15, 2025

Caterpillar Financial Services Corporation (“Cat Financial”) has decided to close the Cat Financial PowerInvestment Notes program (the “PowerInvestment program”) and will redeem all outstanding PowerInvestment Notes on September 15, 2025 (the “Redemption Date”). We have reached this decision after a strategic review of the competitiveness of this program and the future investment required to maintain a program that meets the expectations of both our investors and the company.

We encourage you to redeem your investment as soon as possible

After August 15, 2025, PowerInvestment Notes (both Retail Tier and Corporate Tier) will yield 0.00% interest. Please act now to proactively redeem the full balance of your PowerInvestment account. Funds that remain in your account after September 8, 2025, will be redeemed on the Redemption Date and a check for all amounts in your account, including any accrued interest, will be mailed to your address of record and your account will be closed. To avoid waiting for your funds via mail, we encourage you to redeem your investment prior to September 8, 2025. You can redeem your investment as you would normally – writing a check, written redemption, telephone redemption, wire, and ACH redemption. We are suspending electronic transfer fees, check redemption fees, and account minimum balance fees during this period.

Please discontinue any future investments and delete PowerInvestment routing instructions you may maintain with external accounts

New investments made to your PowerInvestment account will be rejected after August 15, 2025. Please act now to stop any automatic contributions or redemptions you have in place to avoid rejection in the future. This includes automatic contributions from your bank account, payroll, pension and Social Security. Also, please suspend automatic or ad hoc redemptions (to make mortgage, credit card or other payments) involving your PowerInvestment account. Investor initiated redemptions will be rejected after September 8, 2025. Cat Financial will not reimburse investors for fees or costs incurred due to rejected transactions.

Normal operations will continue until closure

I make automated investments into (from payroll, pension or Social Security income) or automated redemptions (to other financial institutions or beneficiaries) from my PowerInvestment account by external payees. Can you provide me with assistance in updating these instructions?

No, we cannot update instructions on behalf of an investor for any payee that may be authorized to send investments or redeem funds from your PowerInvestment account. Please contact this payee as soon as possible to update instructions. Investments will be rejected and returned to the sender after August 15, 2025, and automated ACH redemptions will be suspended on September 8, 2025.
