|:---|:---|:---|:---|

| Distribution and/or Service (12b-1) Fees | 0.25% | 0.25% |  |

<sup>(1)</sup> Unless you are otherwise eligible to purchase Class A1 shares without a sales charge, a contingent deferred sales charge (CDSC) of up to 0.25% will be charged on Class A1 shares redeemed within 12 months of purchase if you paid no sales charge on the original purchase and a finder's fee was paid.

<sup>(2)</sup> Accounts with balances below $1,000 are generally subject to a $5 quarterly fee (with an annual maximum of $20 per account). Shares from such accounts are redeemed each quarter to cover the fee, which is returned to the Fund to offset small account expenses.

<sup>(3)</sup> Management fees have been restated to reflect current fees as a result of a reduction in the Fund's contractual management fee rate effective October 17, 2025.

<sup>(4)</sup> abrdn Funds (the "Trust") and abrdn Inc. (the "Adviser") have entered into a written contract limiting operating expenses to 0.70% for Class A shares, 0.70% for Class A1 shares and 0.45% for Institutional Class shares. This contractual limitation may not be terminated without the approval of the Independent Trustees before February 28, 2027. This limit includes Rule 12b-1 Fees, but excludes certain expenses, including any interest, brokerage commissions, expenses incurred indirectly by the Fund as a result of investments in other investment companies and pooled investment vehicles ("acquired fund fees and expenses" or "AFFE") (but includes AFFE for affiliated investment vehicles managed by the Adviser), and extraordinary expenses. The Trust is authorized to reimburse the Adviser for management fees previously limited and/or for expenses previously paid by the Adviser, provided, however, that any reimbursements must be paid at a date not more than three years after the date when the Adviser limited the fees or reimbursed the expenses and the reimbursements do not cause a Class to exceed the lesser of the applicable expense limitation in the contract at the time the fees were limited or expenses are paid or the applicable expense limitation in effect at the time the expenses are being recouped by the Adviser.
