In our opinion and to the best of our information and according to the explanations given to us these standalone financial results:

i. are presented in accordance with the requirements of Regulation 33 of the Listing Regulations in this regard; and
ii. give a true and fair view in conformity with the recognition and measurement principles laid down in the applicable accounting standards and other accounting principles generally accepted in India of the net profit and other comprehensive income and other financial information for the quarter ended 31st March, 2026 as well as the year-to-date results for the period from 1st April, 2025 to 31st March, 2026.

Management's Responsibilities for the Standalone Financial Results

These quarterly financial results as well as the year-to-date standalone financial results have been prepared on the basis of the standalone financial statements. The Company's Board of Directors are responsible for the preparation of these financial results that give a true and fair view of the net profit and other comprehensive income and other financial information in accordance with the Accounting Standards prescribed under Section 133 of the Act read with relevant rules issued thereunder and other accounting principles generally accepted in India and in compliance with Regulation 33 of the Listing Regulations. 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 results that give a true and fair view and are free from material misstatement, whether due to fraud or error.

In preparing the standalone financial results, the Board of Directors are 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 the Board of Directors either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

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

Auditor's. Responsibilities for the Audit of the Standalone Financial Results.

Our objectives are to obtain reasonable assurance about whether the standalone financial results 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 results.

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

• Identify and assess the risks of material misstatement of the standalone financial results, whether due to fraud or error, design and perform audit procedures responsive to these 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.

8

• Obtain an understanding of internal 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 company's internal control.

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

• Conclude on the appropriateness of the Board of Directors' 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 financial results 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 results, including the disclosures, and whether the financial results represent the underlying transactions and events in a manner that achieve fair presentation.

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.

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.

Other matters

1. We did not review or audit the financial information pertaining to Sigma Advanced Systems Private Limited (Transferor Company), which has been merged with the Company pursuant to the Scheme of Amalgamation, for the quarter and year ended 31st March 2025, the financial effects of which have been included in the restated comparative figures presented in the accompanying Statement. These figures have been taken based on the annual audited financial statements for the year ended 31st March 2025, which were audited by another auditor who expressed an unmodified opinion thereon.

Accordingly, our review conclusion on the Statement, insofar as it relates to the restated comparative figures for the aforesaid periods pertaining to the Transferor Company, is based solely on such financial information, and we do not express any separate conclusion on the financial information of the Transferor Company for the said periods.

8

1. The Statement includes the results for the quarter ended 31st March 2026, being the balancing figure between the audited figures in respect of the full financial year and the published unaudited year to date figures up to the third quarter of the current financial year which were subject to limited review by us.

Our opinion is not modified with respect to above-mentioned matters.

We conducted our audit in accordance with the Standards on Auditing (SAs) specified under section 143(10) of the Companies Act, 2013 (the Act). Our responsibilities under those Standards are further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Results section of our report. We are independent of the Group, 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 financial statements under the provisions of the Companies Act, 2013 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 obtained by us and other auditors in terms of their reports referred to in “Other Matter” paragraph below, is sufficient and appropriate to provide a basis for our opinion.

Directors. The Holding Company's Board of Directors are responsible for the preparation and presentation of the Statement that gives a true and fair view of the consolidated net profit and consolidated total comprehensive income and other financial information of the Group and its associate in accordance with the applicable Indian Accounting Standards prescribed under Section 133 of the Act read with relevant rules issued thereunder and other accounting principles generally accepted in India and in compliance with Regulation 33 of the Listing regulations.

The respective Board of Directors of the companies included in the Group are responsible for maintenance of adequate accounting records in accordance with the provisions of the Act for safeguarding the assets of the Group and its associate 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 the 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 Statement that gives 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 this Consolidated Financial Results by the Directors of the Holding Company, as aforesaid.

In preparing the consolidated financial results, the respective Board of Directors of the companies included in the Group are responsible for assessing the ability of the Group to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the respective Board of Directors either intends to liquidate the Group or to cease operations, or has no realistic alternative but to do so.

The respective Board of Directors of the companies included in the Group and its associate are responsible for overseeing the financial reporting process of the Group and its associate.

Auditor's Responsibilities for the Audit of the Consolidated Financial Results

Our objectives are to obtain reasonable assurance about whether the consolidated financial results 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 consolidated financial results.

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

• Identify and assess the risks of material misstatement of the Consolidated financial results, 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, but not for the purpose of expressing an opinion on the effectiveness of the company's internal control.

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

• Conclude on the appropriateness of the Board of Directors' 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 financial results 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 Consolidated financial results, including the disclosures, and whether the financial results represent the underlying transactions and events in a manner that achieves fair presentation.

• Obtain sufficient appropriate audit evidence regarding the financial results/financial information of the entities within the Group to express an opinion on the consolidated Financial Results. We are responsible for the direction, supervision and performance of the audit of financial information of such entities included in the consolidated financial results of which we are the independent auditors. For the other entities included in the consolidated Financial Results, which have been audited by other auditors, such other auditors remain responsible for the direction, supervision and performance of the audits carried out by them. We remain solely responsible for our audit opinion.

We communicate with those charged with governance of the Holding Company and such other entities included in the consolidated financial results of which we are the independent auditors 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.

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.

We also performed procedures in accordance with the circular issued by the SEBI under Regulation 33(8) of the Listing Regulations, as amended, to the extent applicable.
