KeyBank Personal Checking, Savings, Money Market Savings, and CD accounts are excluded. Qualifying balances are limited to accounts owned by the eligible owners of the Key Business Select Money Market Savings account enrolled in this Bonus Interest Rate offer.

Yes. Withdrawals during the account cycle from any KeyBank Business checking, savings, money market savings, or CD account owned by the eligible owners of the Key Business Select Money Market Savings® account enrolled in the Bonus Interest Rate offer may negatively impact your average Total Relationship Deposit Balance and result in you not meeting the Total Relationship Deposit Balance growth requirement. Withdrawals during the month from any KeyBank checking, savings, or money market savings account owned by the eligible owners of the Key Business Select Money Market Savings® account enrolled in the bonus interest rate offer may negatively impact your average total liquid deposit balance and result in you not meeting the total liquid deposit balance growth requirement.
The Bonus Offer Period begins on the date your account is enrolled in the Bonus Interest Rate offer and ends 6 MONTHS later. The Bonus Offer Period is fixed, includes the introductory Grace Period, and is not extended by meeting or failing to meet the Bonus Interest Rate requirements.
To provide you time to grow your Total Relationship Deposit or Liquid Deposit Balance(s), beginning on the date your account is enrolled in this offer, you will automatically receive the Bonus Interest Rate through the end of your first full account cycle, referred to as the Grace Period. At the end of the Grace Period and each account cycle thereafter during the 6-Month Bonus Offer Period, KeyBank will determine whether you continue to meet the Bonus Interest Rate requirements.

This offer page describes two separate Bonus Interest Rate offer options for a Key Business Select Money Market Savings account. Subject to the applicable offer terms, qualification requirements, balance growth requirement, and redemption deadline, each offer may be redeemed on a new or existing Key Business Select Money Market Savings account. Offers cannot be combined.
Offer 1 — OFFER CODE - VRM10926
Balance growth requirement: $25,000 or more.
Offer redemption period: 9/19/2026 - 11/4/2026.
Offer 2 — OFFER CODE - VRM20926
Balance growth requirement: $100,000 or more.
Offer redemption period: 9/19/2026 - 11/4/2026.
To qualify for the selected 6 Month Bonus Interest Rate, you must: (1) select one offer from the options above and enroll your new or existing Key Business Select Money Market Savings account in the applicable Bonus Interest Rate offer with the applicable offer code by the redemption deadline; (2) meet the balance growth requirement for the selected offer option shown above; and (3) maintain that growth for the period of the Bonus Interest Rate offer. The applicable Bonus Interest Rate applies to the entire balance in the enrolled Key Business Select Money Market Savings account.
Factors That May Affect Qualification: Certain account restrictions on your Key Business Select Money Market Savings account or any other account used to determine your Total Relationship Deposit Balance or Total Liquid Deposit Balance may negatively impact your ability to meet the balance growth requirement and may result in you not qualifying for the Bonus Interest Rate. Any ownership changes to the enrolled Key Business Select Money Market Savings account will require a recalculation of your Initial Average Total Relationship Deposit Balance or Initial Average Total Liquid Deposit Balance and may impact eligibility. Closures or changes in ownership of eligible accounts used to calculate balance growth during the Bonus Offer Period may affect eligibility for the Bonus Interest Rate and your account’s applicable interest rate. For complete definitions of the terms used in this disclosure, please see the Definitions section at the end.
To provide you time to grow your Total Relationship Deposit Balance or Total Liquid Deposit Balance, beginning on the date your account is enrolled in this offer, you will automatically receive the Bonus Interest Rate through the end of your first full account cycle ("Grace Period"). At the end of the Grace Period and each account cycle thereafter during the Bonus Offer Period, KeyBank will determine whether you continue to meet the Bonus Interest Rate requirements.
When requirements are not met, the account will earn the Variable Standard Interest Rate or Variable Relationship Interest Rate in effect at that time until requirements are met again during the Bonus Offer Period. At the expiration of the Bonus Offer Period, the Bonus Interest Rate will no longer apply, and the account will earn interest at the Variable Standard Interest Rate or Variable Relationship Interest Rate in effect at that time. Such rates are variable and may change before, during, or after the Bonus Offer Period.
The Variable Bonus Annual Percentage Yield ("APY") is a blended/composite APY calculated using the 6 Month Bonus Interest Rate and the Variable Standard Interest Rate. Your actual APY may be lower depending on whether you continue to meet the requirements throughout the Bonus Offer Period. One or more balance tiers may earn the same interest rate, and certain tiers may earn the same interest rate under both the Standard Interest Rate and 6 Month Bonus Interest Rate.

This Bonus Interest Rate Offer Code can only be used once per account for the life of the offer. You cannot combine this Bonus Interest Rate offer with another Bonus Interest Rate offer. If you enroll in another Bonus Interest Rate offer, this offer will be terminated and the new Bonus Interest Rate offer requirements will take effect from the time the new offer is redeemed. KeyBank is not responsible for, and will not honor, promotional offers that appear on non-KeyBank websites or that are not authorized by KeyBank.
DEFINITIONS

The Bonus Offer Period is fixed, includes the introductory Grace Period, and is not extended by meeting or failing to meet the Bonus Interest Rate requirements.
Full Account Cycle: A full account cycle (“account cycle”) is the period between the dates when either the account is opened and interest is paid on your account or the time between interest payments (example, from your last interest payment date to your next interest payment date). This period typically aligns with your statement period but may differ. Refer to your interest payment dates for exact timing.
End-of-Day Balances: End-of-day balances are the balances in eligible KeyBank deposit accounts at the close of processing for a given day, after all transactions posted to those accounts for that day are applied. End-of-day balances across eligible accounts are used to determine Total Relationship Deposit Balances and Total Liquid Deposit Balances for purposes of this Bonus Interest Rate offer.
