Exhibit 99.1

A SPAC III Acquisition Corp.

PFIC Annual Information Statement

This statement is provided to shareholders

of A SPAC III Acquisition Corp. (the “Company”) who are United States persons for purposes of the U.S. Internal Revenue Code

of 1986, as amended (the “Code”), and who may be required to file U.S. federal income tax returns. This statement is intended

solely to assist such shareholders (“Shareholders”) in determining the U.S. federal income tax consequences of their investment

in the Company.

Based on the Company’s financial

information for the taxable year beginning January 1, 2025 and ending December 31, 2025, the Company believes that it may be treated as

a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes for such taxable year. The following information

is provided to allow a Shareholder of the Company to make an election under Section 1295 of the Internal Revenue Code to treat the Company

as a Qualified Electing Fund (“QEF Election”) for U.S. federal income tax purposes.

A QEF election, if made, must be made

by the Shareholder and cannot be made by the Company on behalf of any Shareholder. The PFIC rules are complex and may have significant

tax consequences. Shareholders are strongly encouraged to consult their own tax advisors regarding the application of the PFIC rules and

the advisability of making a QEF election with respect to their investment in the Company.

(1) This PFIC Annual Information Statement applies to the Company’s taxable year

Beginning

1/1/2025

Ending

12/31/2025

(2) The Shareholder’s per-share, per-day ordinary earnings and net capital gain information is provided below.

Due to significant

changes in the number of shares outstanding during the taxable year as a result of shareholder redemptions, the Company has determined

per-share, per-day amounts using a time-segmented methodology that reflects the actual number of shares outstanding during each relevant

period.

Segment 1: January 1, 2025 – October

26, 2025

Days: 300

Shares outstanding (Class A and Class B combined):

8,055,000

Entity Name

Ordinary Earnings (US$)

Net Capital Gains (US$)

A SPAC III Acquisition Corp.

0.000616487

NONE

Segment 2: October 27, 2025 – December 31, 2025

Days:

65

Shares

outstanding (Class A and Class B combined): 2,337,581

Entity Name

Ordinary Earnings (US$)

Net Capital Gains (US$)

A SPAC III Acquisition Corp.

0.002124334

NONE

We recommend that all U.S. taxpayers consult a tax advisor

concerning the overall tax consequences of their ownership in the Company and their U.S. tax reporting requirements

(3) The amount of cash and fair market value of other property distributed or deemed distributed by the Company to the Shareholder during

the Company’s taxable period specified in paragraph (1) is as follows:

Cash:

NONE

Fair Market Value of Other Property:

NONE

The Company’s redemption of shares is generally treated

as a disposition for U.S. federal income tax purposes. Shareholders should consult their tax advisors regarding the calculation of gain

or loss.

(4) The Company will permit the Shareholder to inspect and copy the Company’s permanent books of account, records, and such other

documents as may be maintained by the Company that are necessary to establish that PFIC ordinary earnings and net capital gain, as provided

in Section 1293(e) of the Internal Revenue Code, are computed in accordance with U.S. income tax principles, and to verify these amounts

and the Shareholder’s pro rata share thereof.
