1. We have audited the accompanying standalone
financial statements of Clean Science and Technology
Limited ("the Company"), which comprise the
Standalone Balance Sheet as at March 31, 2025, and
the Standalone Statement of Profit and Loss (including
Other Comprehensive Income), the Standalone
Statement of Changes in Equity and the Standalone
Statement of Cash Flows for the year then ended,
and notes to the standalone financial statements,
including material accounting policy information and
other explanatory information.

2. In our opinion and to the best of our information
and according to the explanations given to us, the
aforesaid standalone financial statements give the
information required by the Companies Act, 2013
("the Act") in the manner so required and give a
true and fair view in conformity with the accounting
principles generally accepted in India, of the state

of affairs of the Company as at March 31, 2025, and
total comprehensive income (comprising of profit and
other comprehensive income), changes in equity and
its cash flows for the year then ended.

BASIS FOR OPINION

3. We conducted our audit in accordance with the
Standards on Auditing (SAs) specified under Section
143(10) of the Act. Our responsibilities under those
Standards are further described in the "Auditor's
Responsibilities for the Audit of the Standalone
Financial Statements" section of our report. We
are independent of the Company in accordance
with the Code of Ethics issued by the Institute of
Chartered Accountants of India together with the
ethical requirements that are relevant to our audit
of the standalone financial statements under the
provisions of the Act and the Rules thereunder, and
we have fulfilled our other ethical responsibilities in
accordance with these requirements and the Code
of Ethics. We believe that the audit evidence we have
obtained is sufficient and appropriate to provide a
basis for our opinion.

OTHER INFORMATION

5. The Company's Board of Directors is responsible
for the other information. The other information
comprises the information included in the Annual
report, but does not include the standalone financial
statements and our auditor's report thereon.

Our opinion on the standalone financial statements
does not cover the other information and we do not
express any form of assurance conclusion thereon.

In connection with our audit of the standalone
financial statements, our responsibility is to read the
other information and, in doing so, consider whether
the other information is materially inconsistent with
the standalone financial statements or our knowledge
obtained in the audit or otherwise appears to be
materially misstated. If, based on the work we have
performed, we conclude that there is a material
misstatement of this other information, we are
required to report that fact.

We have nothing to report in this regard.

RESPONSIBILITIES OF MANAGEMENT AND THOSE

CHARGED WITH GOVERNANCE FOR THE STANDALONE

FINANCIAL STATEMENTS

6. The Company's Board of Directors is responsible
for the matters stated in Section 134(5) of the Act
with respect to the preparation of these standalone
financial statements that give a true and fair view
of the financial position, financial performance,
changes in equity and cash flows of the Company in
accordance with the accounting principles generally
accepted in India, including the Indian Accounting
Standards specified under Section 133 of the Act.
This responsibility also includes maintenance of
adequate accounting records in accordance with the

provisions of the Act for safeguarding of the assets of
the Company and for preventing and detecting frauds
and other irregularities; selection and application of
appropriate accounting policies; making judgments
and estimates that are reasonable and prudent;
and design, implementation and maintenance
of adequate internal financial controls, that were
operating effectively for ensuring the accuracy and
completeness of the accounting records, relevant to
the preparation and presentation of the standalone
financial statements that give a true and fair view and
are free from material misstatement, whether due to
fraud or error.

7. In preparing the standalone financial statements,
management is responsible for assessing the
Company's ability to continue as a going concern,
disclosing, as applicable, matters related to going
concern and using the going concern basis of
accounting unless management either intends to
liquidate the Company or to cease operations, or has
no realistic alternative but to do so.

8. Those Board of Directors are also responsible for
overseeing the Company's financial reporting process.

AUDITOR'S RESPONSIBILITIES FOR THE AUDIT OF

THE STANDALONE FINANCIAL STATEMENTS

9. Our objectives are to obtain reasonable assurance
about whether the standalone financial statements as
a whole are free from material misstatement, whether
due to fraud or error, and to issue an auditor's report
that includes our opinion. Reasonable assurance
is a high level of assurance but is not a guarantee
that an audit conducted in accordance with SAs will
always detect a material misstatement when it exists.
Misstatements can arise from fraud or error and are
considered material if, individually or in the aggregate,

they could reasonably be expected to influence the
economic decisions of users taken on the basis of
these standalone financial statements.

10. As part of an audit in accordance with SAs, we exercise
professional judgement and maintain professional
scepticism throughout the audit. We also:

• Identify and assess the risks of material
misstatement of the standalone financial
statements, whether due to fraud or error, design
and perform audit procedures responsive to
those risks, and obtain audit evidence that is
sufficient and appropriate to provide a basis for
our opinion. The risk of not detecting a material
misstatement resulting from fraud is higher
than for one resulting from error, as fraud may
involve collusion, forgery, intentional omissions,
misrepresentations, or the override of internal
control.

• Obtain an understanding of internal control
relevant to the audit in order to design
audit procedures that are appropriate in the
circumstances. Under Section 143(3)(i) of the
Act, we are also responsible for expressing our
opinion on whether the Company has adequate
internal financial controls with reference to
standalone financial statements in place and the
operating effectiveness of such controls.

• Evaluate the appropriateness of accounting
policies used and the reasonableness of
accounting estimates and related disclosures
made by management.

• Conclude on the appropriateness of
management's use of the going concern basis
of accounting and, based on the audit evidence
obtained, whether a material uncertainty exists
related to events or conditions that may cast
significant doubt on the Company's ability to
continue as a going concern. If we conclude that
a material uncertainty exists, we are required
to draw attention in our auditor's report to the
related disclosures in the standalone financial
statements or, if such disclosures are inadequate,
to modify our opinion. Our conclusions are based
on the audit evidence obtained up to the date of
our auditor's report. However, future events or
conditions may cause the Company to cease to
continue as a going concern.

• Evaluate the overall presentation, structure and
content of the standalone financial statements,
including the disclosures, and whether the
standalone financial statements represent the
underlying transactions and events in a manner
that achieves fair presentation.

11. We communicate with those charged with governance
regarding, among other matters, the planned scope
and timing of the audit and significant audit findings,
including any significant deficiencies in internal
control that we identify during our audit.

12. We also provide those charged with governance with
a statement that we have complied with relevant
ethical requirements regarding independence, and to
communicate with them all relationships and other
matters that may reasonably be thought to bear on
our independence, and where applicable, related
safeguards.

13. From the matters communicated with those charged
with governance, we determine those matters
that were of most significance in the audit of the
standalone financial statements of the current period
and are therefore the key audit matters. We describe
these matters in our auditor's report unless law or
regulation precludes public disclosure about the
matter or when, in extremely rare circumstances, we
determine that a matter should not be communicated
in our report because the adverse consequences of
doing so would reasonably be expected to outweigh
the public interest benefits of such communication.

OTHER MATTER

14. The standalone financial statements of the Company
for the year ended March 31, 2024, were audited by
another firm of chartered accountants under the Act
who, vide their report dated May 15, 2024, expressed
an unmodified opinion on those standalone financial
statements.
