Report on the Audit of Standalone Financial Statements

OPINION

We have audited the accompanying standalone financial statements of Data Infrastructure Trust (formerly known as Tower Infrastructure Trust)(“the Trust”), which comprise the Standalone Balance Sheet as at March 31, 2023, Standalone Statement of Profit and Loss including Statement of Other Comprehensive Income, Statement of Changes in Unitholders' Equity, Standalone Statement of Cash Flows for the year then ended, Standalone Statement of Net Assets at Fair Value as at March 31, 2023 and Standalone Statement of Total Returns at Fair Value and Net Distributable Cash Flows for the year then ended and a summary of significant accounting policies and other explanatory information.

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 Securities and Exchange Board of India (Infrastructure Investment Trusts) Regulations, 2014 as amended from time to time including any guidelines and circulars issued thereunder read with the SEBI circular number CIR/IMD/DF/114/2016, dated October 20, 2016 (together referred to as the "InvIT Regulations") in the manner so required and give a true and fair view in conformity with the Indian Accounting Standards as defined in Rule 2(1)(a) of the Companies (Indian Accounting Standards) Rules, 2015 (as amended), and other accounting principles generally accepted in India, to the extent not inconsistent with the InvIT Regulations, of the state of affairs of the Trust as at March 31,2023, and its profit including other comprehensive income, its changes in unitholders' equity, its cash flows for the year ended March 31,2023, its net assets at fair value as at March 31,2023, its total returns at fair value and net distributable cash flows for the year ended on that date and other financial information of the Trust.

BASIS FOR OPINION

We conducted our audit of the standalone financial statements in accordance with the Standards on Auditing (SAs) issued by the Institute of Chartered Accountants of India (ICAI). Our responsibilities under those Standards are further described in the Auditor's Responsibility for the Audit of the Standalone Financial Statements section of our report. We are independent of the Trust in accordance with the Code of Ethics issued by the ICAI and we have fulfilled our other ethical responsibilities in accordance with these requirements and the ICAI's Code of Ethics. We believe that the audit evidence obtained by us is sufficient and appropriate to provide a basis for our audit opinion on the standalone financial statements.

EMPHASIS OF MATTER

We draw attention to Note 2.2 (i) which describes the presentation of “Unit Capital” as “Equity” to comply with InvIT Regulations. Our opinion is not modified in respect of this matter.

KEY AUDIT MATTERS

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the standalone financial statements of the current year. These matters were addressed in the context of our audit of the standalone financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. We have determined the matters described below to be the key audit matters to be communicated in our report.

Information Other than the Financial Statements and Auditor’s Report Thereon

• Brookfield India Infrastructure Manager Private Limited ('Investment Manager') acting in its capacity as an Investment Manager of the Trust is responsible for the other information. The other information comprises the information and disclosures included in the Annual Report but does not include the standalone financial statements, consolidated financial statements and our auditor's report thereon.

• Our opinion on the standalone financial statements does not cover the other information and we will 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 during the course of our 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

The Management of Investment Manager (“the Management”), is responsible for the preparation of these standalone financial statements that give a true and fair view of the financial position, financial performance including other comprehensive income, changes in unitholders' equity, cash flows for the year ended March 31,2023, net assets at fair value as at March 31,2023, total returns at fair value and net distributable cash flows for the year ended on that date of the Trust in accordance with the InvIT Regulations, the Indian Accounting Standards as defined in Rule 2(1)(a) of the Companies (Indian Accounting Standards) Rules, 2015 (as amended) and other accounting principles generally accepted in India, to the extent not inconsistent with InvIT Regulations.

This responsibility also includes maintenance of adequate accounting records for safeguarding the assets of the Trust 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 which have been used for the purpose of preparation of the financial statements by the Investment Manager of the Trust, as aforesaid.

In preparing the standalone financial statements, the management is responsible for assessing the Trust'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 the Board of Directors of Investment Manager either intends to liquidate the Trust or to cease operations, or has no realistic alternative but to do so.

The Investment Manager's Board of Directors is also responsible for overseeing the Trust's financial reporting process. Auditor’s Responsibility for the Audit of the Standalone Financial Statements

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.

As part of an audit in accordance with SAs, we exercise professional judgment 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 financial control relevant to the audit in order to design audit procedures that are appropriate in the circumstances but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control.

• 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 Trust'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 Trust 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.

Materiality is the magnitude of misstatements in the standalone financial statements that, individually or in aggregate, makes it probable that the economic decisions of a reasonably knowledgeable user of the standalone financial statements may be influenced. We consider quantitative materiality and qualitative factors in (i) planning the scope of our audit work and in evaluating the results of our work; and (ii) to evaluate the effect of any identified misstatements in the standalone financial statements.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, that we identify during our audit.

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.

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 year 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.

Report on Other Legal and Regulatory Requirements

Based on our audit and as required by InvIT Regulations, we report that:

a) We have obtained all the information and explanations which, to the best of our knowledge and belief were necessary for the purpose of our audit;

b) The Standalone Balance sheet, and Standalone Statement of Profit and Loss including Other Comprehensive Income, Statement of Changes in Unitholders' Equity, Standalone Statement of Cash Flows, dealt with by this Report are in agreement with the relevant books of account of the Trust;

c) In our opinion, the aforesaid standalone financial statements comply with the Indian Accounting Standards as defined in Rule 2(1)(a) of the Companies (Indian Accounting Standards) Rules, 2015 (as amended), and other accounting principles generally accepted in India, to the extent not inconsistent with the InvIT Regulations.
