BUSINESS OF THE MEETING
Explanatory Information
Approval of Issue of Shares on Conversion of
Convertible Notes for Nasdaq Listing Rule 5635(d) and Board Approval Purposes
General Information
The Company has entered into, and issued, a debt
financing arrangement (Financing) involving convertible notes (Notes) to an unrelated institutional investor (Noteholder) approved by
the Directors on 7 May 2026 (Closing Date), as detailed in the Report on Form 6-K filed with the U.S. Securities and Exchange Commission
(SEC) on 26 May 2026. Resolution 1 seeks shareholder approval to issue shares upon redemption or conversion of the Notes, including above
the 19.99% limit as provided for in Nasdaq Listing Rule 5635(d). The Company expects to use the proceeds from the Financing to support
its strategic initiatives, including:
| ● | accelerating commercialisation activities; |
| ● | supporting clinical trial and regulatory programs; |
| ● | scaling operational capabilities; |
| ● | supporting existing and future revenue opportunities; and |
| ● | strengthening the Company’s working capital and financial
flexibility. |
The Directors believe the financing and the transactions
contemplated by the Notes will assist the Company in continuing to execute its growth and commercialisation strategy.
The Notes may convert into fully paid ordinary
shares in the Company (Shares) in accordance with their terms as outlined in the Report on Form 6-K as filed with the SEC on 26 May 2026.
Shares may become issuable under or in connection with the Notes in respect of all amounts payable or convertible under the Notes, including
principal, accrued interest, default interest, capitalised interest, fees, costs and any premium payable under the Notes, in each case
to the extent permitted by the terms of the Notes. The conversion provisions include pricing mechanisms such as discounts, valuation caps,
formulas or other adjustment mechanisms that determine the number of Shares to be issued upon conversion or otherwise in satisfaction
of amounts owing under the Notes which can be found in detail in the Report on Form 6-K as filed with the SEC on 26 May 2026.
| Gelteq Ltd | ACN: 31 619 501 254 | W: www.gelteq.com | Page 3 of 7 |

The Noteholder is not a related party of the Company
for the purposes of Chapter 2E of the Corporations Act and, so far as the Directors are aware, is otherwise unrelated to the Company,
its Directors and its substantial shareholders. So far as the Directors are aware, the Noteholder has no associates for the purposes of
Chapter 6 of the Corporations Act other than its affiliates, if any, whose interests are required to be aggregated with the Noteholder
under the terms of the Notes or applicable law.
A summary of the material terms of the Notes is
as follows: the Notes constitute debt obligations of the Company, have a principal amount and maturity, bear interest and may include
default interest, fees, costs, premiums and other amounts payable in accordance with their terms, may be converted into Shares in accordance
with their terms, and may also give rise to the issue of Shares in connection with amounts payable or convertible under the Notes, including
principal, accrued interest, default interest, capitalised interest, fees, costs and premiums. The number of Shares issuable will depend
on the operation of the conversion formula and other terms of the Notes at the relevant time, including any applicable discount, valuation
cap, formula, adjustment or other pricing mechanism, and may be affected by customary anti-dilution or other adjustment provisions, events
of default, prepayment, waiver or amendment provisions and any contractual beneficial ownership limitation contained in the Notes. Depending
on how those terms operate over time, the issue of Shares under or in connection with the Notes may have a material dilutive effect on
existing shareholders and may affect the Company’s control profile.
Purpose of the Proposal
The purpose of Resolution 1 is to obtain shareholder approval for
the purposes of Nasdaq Listing Rule 5635(d) and all other applicable purposes, including approval for:
| ● | the Company’s entry into, issue of and performance of
the Notes; |
| ● | the issuance of Shares under or in connection with the Notes
in excess of 19.99% of the shares outstanding, measured on the date the Company and the Noteholder entered into definitive transaction
documents. |
Effect of the Proposal
If Resolution 1 is passed:
| ● | The Company will have obtained the shareholder approval required
by Nasdaq Listing Rule 5635(d) and as a result will be permitted to issue Shares up to and exceeding 19.99% of the Company’s outstanding
shares, measured as of the date of execution of the definitive documents, pursuant to or in connection with the Notes; and |
| ● | the Directors will be authorised to allot and issue those Shares
without further shareholder approval. |
If Resolution 1 is not passed, the Company may be unable to proceed
with the second closing of the Notes pursuant to purchase agreement entered into in connection with Notes.

Shares Issuable Under or in Connection with
the Notes
The number of Shares that may be issued under
or in connection with the Notes cannot be determined with certainty at the date of this Notice because it will depend on the terms of
the Notes, including where:
| ● | the operation of the conversion provisions in the Notes; |
| ● | the applicable discount, valuation cap or pricing mechanism
applies; |
| ● | the amount of Notes converted and any amounts payable or convertible
under the Notes, including principal, accrued interest, default interest, capitalised interest, fees, costs and premiums; and |
| ● | the Company’s capital structure at the time of conversion
or issue. |
By way of illustration only, assuming:
| ● | both convertible notes remain outstanding until maturity with
no limited conversions; |
| ● | all amounts payable under the notes, including principal, original
issue discount, fees and accrued interest, are satisfied through the issue of Shares; |
| ● | the applicable conversion price is the floor price of US$0.50
per Share throughout the term of the notes; and |
| ● | no penalties, default interest or additional adjustment amounts
become payable, the maximum theoretical number of Shares that could be issued under or in connection with the Notes would be approximately
8,908,548 Shares. This figure is illustrative only and the actual number of Shares issued may be materially lower or higher depending
on the operation of the terms of the Notes, including the timing and amount of conversions, accrued amounts payable under the Notes,
the applicable conversion price at the relevant time, and changes to the Company’s capital structure. |
The Notes contain a contractual beneficial ownership limitation which
restricts the Noteholder, together with its affiliates and any associates whose interests are required to be aggregated under the Notes
or applicable law, from beneficially owning more than 9.99% of the Company’s issued and outstanding Shares at any given time.
Accordingly, the Noteholder is contractually restricted
from converting the Notes to the extent that such conversion would result in the Noteholder and the persons referred to in that limitation
beneficially owning more than 9.99% of the Company’s issued and outstanding Shares at the relevant time.
On that basis, and taking into account assumptions
currently considered reasonable by the Directors regarding the operation of the Notes and the Company’s capital structure, the maximum
voting power that may result from Shares issued under or in connection with the Notes is disclosed as 9.99% of the voting power in the
Company.
The disclosure above is based on the contractual
beneficial ownership limitation in the Notes. The actual number of Shares issued and the extent of dilution to existing shareholders may
differ depending on circumstances existing at the relevant time, including changes to the Company’s issued share capital prior to
conversion or issue. By way of illustration only, the higher the amount outstanding under the Notes and the lower the applicable conversion
price, the greater the number of Shares that may be issued and the greater the potential dilution to existing shareholders. That dilution
may be material and may occur progressively over time. However, the voting power of the Noteholder following conversion or issue remains
subject to the 9.99% cap described above.
The foregoing summary of the Financing and Note
are not complete and are subject to, and are qualified in their entirety by reference to, the full text of the forms of such documents,
which are filed as exhibits to the Report on Form 6-K as filed with the SEC on 26 May 2026.

Shareholders should note that shareholder
approval of Resolution 1 does not displace the Directors' duties to act in good faith in the best interests of the Company and for a
proper purpose, or other duties owed under the Corporations Act and applicable general law. In addition, while the Directors who are
justified in doing so consider the Notes and the transactions contemplated by them to be in the best interests of the Company, there
remains residual risk that the conversion or other share issuance mechanics could operate in a manner that has a material dilutive
effect on existing shareholders or affects control of the Company in a way that some shareholders may regard as unfairly
prejudicial. Any Director with a material personal interest in the subject matter of Resolution 1 must deal with that interest in
accordance with the Corporations Act and the Company’s governance requirements. The Directors consider that the disclosures in
this Notice assist shareholders to assess those risks.
Board Recommendation
The Board, other than any Director who is not
justified in making a recommendation because of a material personal interest or other conflict, unanimously recommends that shareholders
vote in favour of Resolution 1.
Each Director who is entitled to do so intends
to vote all Shares under their control in favour of Resolution 1.

to the register of Shareholders after the market closed on 15 May 2026. A proxy appointment and the Proxy Form must be received by the
