Independent Auditor’s Report

Report No. 01320/2.1505/AU.1/06/0687-4/1/V/2026

The Shareholders and the Boards of Commissioners and Directors

Perusahaan Perseroan (Persero) PT Telekomunikasi Indonesia Tbk.

Opinion

We have audited the accompanying consolidated financial statements of Perusahaan Perseroan (Persero) PT Telekomunikasi Indonesia Tbk. (the “Company”) and its subsidiaries (collectively referred to as the “Group”), which comprise the consolidated statement of financial position as of December 31, 2025, and the consolidated statement of profit or loss and other comprehensive income, consolidated statement of changes in equity, and consolidated statement of cash flows for the year then ended, and notes to the consolidated financial statements, including material accounting policy information.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position as of December 31, 2025, and its consolidated financial performance and cash flows for the year then ended, in accordance with Indonesian Financial Accounting Standards.

Basis for opinion

We conducted our audit in accordance with Standards on Auditing established by the Indonesian Institute of Certified Public Accountants (“IICPA”). Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements paragraph of our report. We are independent of the Group in accordance with the ethical requirements relevant to our audit of the consolidated financial statements in Indonesia, and we have fulfilled our other ethical responsibilities in accordance with such requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key audit matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements of the current period. Such key audit matters were addressed in the context of our audit of the consolidated financial statements taken as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on such key audit matters. For the key audit matter below, our description of how our audit addressed such key audit matter is provided in such context.

Report No. 01320/2.1505/AU.1/06/0687-4/1/V/2026 (continued)

Key audit matters (continued)

We have fulfilled the responsibilities described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements paragraph of our report, including in relation to the key audit matter communicated below. Accordingly, our audit included the performance of procedures designed to respond to our assessment of the risks of material misstatement of the accompanying consolidated financial statements. The results of our audit procedures, including the procedures performed to address the key audit matter below, provide the basis for our opinion on the accompanying consolidated financial statements.

Evaluation of telecommunication infrastructure estimated useful lives

Description of the key audit matter:

As of December 31, 2025, the balance of consolidated telecommunication infrastructures amounted to Rp144,713 billion which represents 50% of total consolidated assets. As discussed in Notes 2.z.ii.(b) and 11 to the accompanying consolidated financial statements, the Group reviews the estimated useful lives of its property and equipment, including telecommunication infrastructures, at least annually and such estimates are updated if expectations differ from previous estimates due to changes in expectation of physical wear and tear, technical, or commercial obsolescence, and legal or other limitations on the continuing use of the property and equipment.

Auditing the Group's estimated useful lives of telecommunication infrastructures is complex and requires significant judgment because the determination of the estimated useful lives considers a number of factors, including strategic business plans, expected future technological developments, and market behavior.

Audit response:

We obtained an understanding, and evaluated the design and tested the operating effectiveness, of internal controls over the Group’s process of estimating the useful lives of its telecommunication infrastructures. This includes, among others, testing of management’s review control on checking the completeness and accuracy of the assets classification data and assessing the appropriateness of the judgments regarding the most relevant data to be considered in determining its useful lives.  We also tested management’s control on benchmarking analysis, including the selection criteria, on the estimated useful lives of telecommunication infrastructures.

To test whether the estimated useful lives of telecommunication infrastructures used by management was reasonable, our audit procedures included, among others, obtaining an understanding of management’s strategy related to asset replacements and assessed the reasonableness of assumptions by considering external sources, such as telecommunication technology growth, changes in market demand, and current economic and regulatory trends. We assessed whether the benchmarking analysis on the estimated useful lives of telecommunication infrastructures used by management was complete and consistent with the selection criteria through comparison with sample portfolio of public companies within the telecommunication industry.

Independent Auditor’s Report (continued)

Report No. 01320/2.1505/AU.1/06/0687-4/1/V/2026 (continued)

Emphasis of matter

We draw attention to Note 2.z.iii to the accompanying financial statements, which describes the change in accounting policy on property and equipment and its retrospective application. Our opinion is not modified in respect of this matter.

Other information

Management is responsible for the other information. Other information comprises the information included in the 2025 Annual Report (“The Annual Report”) other than the accompanying consolidated financial statements and our independent auditor’s report thereon. The Annual Report is expected to be made available to us after the date of this independent auditor’s report.

Our opinion on the accompanying consolidated financial statements does not cover the Annual Report, and accordingly, we do not express any form of assurance on the Annual Report.

In connection with our audit of the accompanying consolidated financial statements, our responsibility is to read the Annual Report when it becomes available and, in doing so, consider whether the Annual Report is materially inconsistent with the accompanying consolidated financial statements or our knowledge obtained in the audit, or otherwise appears to be materially misstated.

When we read the Annual Report, if we conclude that there is a material misstatement therein, we are required to communicate the matter to those charged with governance and take appropriate actions based on the applicable laws and regulations.

Responsibilities of management and those charged with governance for the consolidated financial statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with Indonesian Financial Accounting Standards, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the Group’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 Group or to cease its operations, or has no realistic alternative but to do so.

Those charged with governance are responsible for overseeing the Group’s financial reporting process.

Independent Auditor’s Report (continued)

Report No. 01320/2.1505/AU.1/06/0687-4/1/V/2026 (continued)

Auditor’s responsibilities for the audit of the consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements taken as a whole are free from material misstatement, whether due to fraud or error, and to issue an independent 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 Standards on Auditing established by the IICPA 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 statements.

As part of an audit in accordance with Standards on Auditing established by the IICPA, 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 statements, whether due to fraud or error, design and perform audit procedures responsive to such 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 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 Group’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 Group's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our independent auditor’s report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusion is based on the audit evidence obtained up to the date of our independent auditor’s report. However, future events or conditions may cause the Group to cease to continue as a going concern.
--- ---
Evaluate the overall presentation, structure, and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

Auditor's responsibilities for the audit of the consolidated financial statements (continued)

As part of an audit in accordance with Standards on Auditing established by the IICPA, we exercise professional judgment and maintain professional skepticism throughout the audit. We also: (continued)

Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision, and performance of the group audit. We remain solely responsible for our audit opinion.

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.

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

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION

The Group consolidated financial statements have been prepared in accordance with Indonesian Financial Accounting Standards which includes Statements of Financial Accounting Standards ("Pernyataan Standar Akuntansi Keuangan" or “PSAK”) and Interpretations of Financial Accounting Standards ("Interpretasi Standar Akuntansi Keuangan" or “ISAK”) published by the Financial Accounting Standards Board of the Institute of Indonesian Chartered Accountants (Dewan Standar Akuntansi Keuangan Ikatan Akuntan Indonesia or “DSAK IAI”) and Regulation No. VIII.G.7 of the Capital Market and Financial Institution Supervisory Agency (“Bapepam-LK”) regarding the Presentation and Disclosure of Financial Statements of Issuers or Public Companies, enclosed in the decision letter KEP-347/BL/2012.

a. Basis of preparation of the consolidated financial statements

The consolidated financial statements, except for the consolidated statements of cash flows, are prepared on the accrual basis. The measurement basis used is historical cost, except for certain accounts which are measured using the basis mentioned in the relevant notes herein.

The consolidated statements of cash flows are prepared using the direct method and present the changes in cash and cash equivalents from operating, investing, and financing activities.

The reporting currency in the consolidated financial statements is the Indonesian Rupiah (“Rp”) which is also the functional currency of the Group, except for subsidiaries whose functional currencies are the U.S. Dollar, Australian Dollar, Singapore Dollar, and Malaysian Ringgit.

Figures in the consolidated financial statements containing values under Rp1 billion and  US$1 million are presented with zero.

New accounting standards

On January 1, 2025, the Group adopted the new and revised statement of financial accounting standards and interpretations of financial accounting standards effective from that date. Adjustments to the Group's accounting policies have been made as required, in accordance with the transitional provisions of the respective standards and interpretations. The adoption of the new and revised standards and interpretations did not result in major changes to the Group's accounting policies and had no material effect on the amounts reported for the current or prior financial year:

Amendment PSAK 221: Effect of Changes in Foreign Exchange Rate

This amendment clarifies the criteria for interchangeability between two currencies and requires disclosure of information that enables users of financial statements to understand the impact of a currency not being exchangeable. These amendments are not expected to have an impact to the Group’s consolidated financial statement.

PSAK 118: Presentation and Disclosures in Financial Statements

DSAK IAI has issued PSAK 118: Presentation and Disclosures in Financial Statements, which supersedes PSAK 201: Presentation of Financial Statements. PSAK 118 introduces requirements for the presentation of key subtotals, including operating profit or loss, profit or loss before financing and income taxes, and net profit or loss. In addition, PSAK 118 requires that income and expenses be classified into the following categories: operating, investing, and financing, along with income taxes and discontinued operations.

PSAK 118 also addresses the disclosure of Management-defined Performance Measures (“MPM”), which are intended to communicate management’s perspective on the entity’s overall financial performance. The standard elaborates on the role of the primary financial statements and the **** notes to the financial statements, and sets out principles and requirements related to the aggregation and disaggregation of information. These principles apply both to the presentation within the financial statements and to the disclosures. The Group is currently assessing the potential impact of PSAK 118 on its consolidated **** financial statements.

PSAK 119: Subsidiaries Without Public Accountability: Disclosures

The Indonesian Financial Accounting Standards Board (DSAK IAI) has issued PSAK 119: Subsidiaries Without Public Accountability: Disclosures. PSAK 119 sets out disclosure requirements that may be applied by an entity as an alternative to the disclosure requirements in other PSAK. An entity may elect to apply this Standard in its consolidated, separate, or individual financial statements if, and only if, at the end of the reporting period, the entity is a subsidiary without public accountability whose parent prepares consolidated financial statements that are available to the public and comply with Indonesian Financial Accounting Standards (SAK). This amendment is not expected to have a material impact on the consolidated financial statements.

In November 2025, DSAK IAI issued amendments to PSAK 119. The amendments to PSAK 119 include:

i. removal of application in separate financial statements by intermediate parent entities;
ii. removal of disclosure objectives related to financing, suppliers, shortages, or overages, Pillar    Two model, classification and measurement of financial instruments, as well as long term loabilities with covenants;
--- ---
iii. reduction of disclosure requirments related to supplier finance arrangements;
--- ---
iv. removal of material that is guidance based and not disclosure requirements; and
--- ---
v. replacement of management defined performance measure disclosures with a cross reference to PSAK 118.
--- ---

These amendments are not expected to have material impact on the consolidated financial statements.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)
b. Principles of consolidation
--- ---

The consolidated financial statements consist of the financial statements of the Company and  the subsidiaries over which it has control. Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Group controls an investee if and only if the Group has power over the investee, exposure, or rights, to variable returns from its involvement with the investee, and the ability to use its power over the investee to affect its returns.

Generally, there is a presumption that a majority of voting rights results in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

i. the contractual arrangement with the other vote holders of the investee;
ii. rights arising from other contractual arrangements; and
--- ---
iii. the Group's voting rights and potential voting rights.
--- ---

The Group re-assesses whether it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control over the subsidiary. Assets, liabilities, income, and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated statements of financial position and the consolidated statements of profit or loss and other comprehensive income from the date the Group gains financial control until the date the Group ceases to control the subsidiary.

Profit or loss and each component of other comprehensive income (“OCI”) are attributed to the equity holders of the Company and to the non-controlling interests, even if this results in the non-controlling interests having a deficit balance.

All intra-Group assets and liabilities, equity, revenue and expenses, and cash flow relating to transactions within Group are fully eliminated on consolidation.

In case of loss of control over a subsidiary, the Group:

i. derecognizes the assets (including goodwill) and liabilities of the subsidiary at the carrying amounts on the date when it loses control;
ii. derecognizes the carrying amounts of any non-controlling interests of its former subsidiary on the date when it loses control;
--- ---
iii. recognizes the fair value of the consideration received (if any) from the transaction, events, or condition that caused the loss of control;
--- ---
iv. recognizes the fair value of any investment retained in the subsidiary at fair value on the date of loss of control; and
--- ---
v. recognizes any surplus or deficit in profit or loss that is attributable to the Group.
--- ---

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)
c. Transactions **** with related parties
--- ---

The Group has transactions with related parties. The definition of related parties used is in accordance with the Bapepam-LK’s Regulation No. VIII.G.7 regarding the Presentations and Disclosures of Financial Statements of Issuers or Public Companies, enclosed in the decision letter No. KEP-347/BL/2012. The party which is considered a related party is a person or entity that is related to the entity that is preparing its financial statements.

Under the Regulation of Bapepam-LK No. VIII.G.7, a government-related entity is an entity that is controlled, jointly controlled or significantly influenced by the government. Government in this context is the Minister of Finance or the Local Government, as the shareholder of the entity.

Key management personnel are identified as the persons having authority and responsibility for planning, directing, and controlling the activities of the entity, directly or indirectly, including any director (whether executive or otherwise) of the Group. The related party status extends to the key management of the subsidiaries to the extent they direct the operations of subsidiaries with minimal involvement from the Company’s management.

d. Business combinations and goodwill

Business combination is accounted for using the acquisition method. The consideration transferred is measured at fair value, which is the aggregate of the fair value of the assets transferred, liabilities incurred or assumed, and the equity instruments issued in exchange for control of the acquiree. For each business combination, non-controlling interest is measured at fair value or at the proportionate share of the acquiree’s identifiable net assets. The measurement basis is selected on a transaction-by-transaction basis. Acquisition-related costs are expensed as incurred. The acquiree’s identifiable assets and liabilities are recognized at their fair values at the acquisition date.

Goodwill is initially measured at cost, which represents the excess of the aggregate consideration transferred and the amount recognized for non-controlling interests, and any previous interest held, over the net identifiable assets acquired and liabilities assumed. If the fair value of the acquired net assets exceeds the aggregate consideration transferred, the Group re-assesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed, and reviews the procedures used to measure the amounts to be recognized at the acquisition date. If the re-assessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the gain is recognized in profit or loss.

Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Contingent consideration classified as equity is not remeasured and its subsequent settlement is accounted for within equity. Contingent consideration classified as an asset or liability that is a financial instrument and within the scope of PSAK 109, is measured at fair value with the changes in fair value recognized in the statement of profit or loss in accordance with PSAK 109. Other contingent consideration that is not within the scope of PSAK 109 is measured at fair value at each reporting date with changes in fair value recognized in profit or loss.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

d. Business combinations and goodwill (continued)

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Group shall report in its consolidated financial statements provisional amounts for the items for which the accounting is incomplete. During the measurement period, the Group shall retrospectively adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date and, if known, would have affected the measurement of the amounts recognized as of that date. The measurement period ends immediately after the Company receives the information about the facts and circumstances that existed at the acquisition date or learns that additional information cannot be obtained. However, the measurement period must not exceed one year from the date of acquisition.

In a business combination achieved in stages, the acquirer remeasures its previously held equity interest in the acquiree at its acquisition-date fair value and recognizes the resulting gain or loss, if any, in profit or loss.

Based on PSAK 338: Business Combination of Entities Under Common Control, the transfer of assets, liabilities, shares or other ownership instruments among the companies under common control would not result in a gain or loss for the Company or individual entity in the same group. Since the restructuring transaction between entities under common control does not result in a change of the economic substance of the ownership of assets, liabilities, shares, or other instruments of ownership, which are exchanged, assets or liabilities transferred are recorded at book value using the pooling-of-interests method.

In applying the pooling-of-interests method, the components of the financial statements for the period during the restructuring occurred must be presented in such a manner as if the restructuring has occurred since the beginning of the earliest period presented. The excess of consideration paid or received over the carrying value of interest acquired, net of income tax, is directly recognized to equity and presented as “Additional Paid-in Capital” under the equity section of the consolidated statements of financial position.

At the initial application of PSAK 338, all balances of the Difference In Value of Restructuring Transactions of Entities under Common Control was reclassified to “Additional Paid-in Capital” in the consolidated statements of financial position.

e. Cash and cash equivalents

Cash and cash equivalents in the consolidated statements of financial position comprise cash in banks and on hand and short-term highly liquid deposits with a maturity of three months or less, that are readily convertible to a known amount of cash and subject to an insignificant risk of changes in value.

Time deposits with maturities of more than three months but not more than one year are  presented as part of “Other current financial assets” in the consolidated statements of financial position.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

f. Inventories

Inventories consist of Subscriber Identification Module ("SIM") cards, and prepaid vouchers which are expensed upon sale.

Inventories are valued at the lower of cost and net realizable value. Net realizable value is determined by either estimating the selling price in the ordinary course of business, less estimated cost to sell or determining the prevailing replacement costs.

The costs of inventories consist of the purchase price, import duties, other taxes, transport, handling, and other costs directly attributable to their acquisition.

Cost is determined using the weighted average method.

The amounts of any write-down of inventories below cost to net realizable value and all losses  of inventories are recognized as an expense in the period in which the write-down or loss occurs.  The amount of any reversal of any write-down of inventories, arising from an increase in net realizable value, is recognized as a reduction in the amount of general and administrative expenses in the year in which the reversal occurs.

Provision for obsolescence is primarily based on the estimated forecast of future usage of these inventory items.

g. Prepaid expenses

Prepaid expenses are amortized over their future beneficial periods using the straight-line method. Prepaid expenses are presented in the consolidated statements of financial position as part of other current assets and other non-current assets.

h. Non-current assets held for sale

Assets (or disposal groups) are classified as assets held for sale when their carrying amount will be recovered principally through a sale transaction rather than through continuing use, and the sale is highly probable. These assets are measured at the lower of their carrying amount and fair value less costs to sell.

An asset (or disposal group) is considered available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets (or disposal groups), and its sale must be highly probable.

The assets (or disposal groups) classified as held for sale are presented separately from the other assets in the consolidated statements of financial position. The liabilities of disposal group classified as held for sale are presented separately from the other liabilities in the consolidated statements of financial position.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

i. Intangible assets

Intangible assets are recognized if it is highly probable that the expected future economic benefits that are attributable to each asset will flow to the Group, and the cost of the asset can be reliably measured.

Intangible assets are stated at cost less accumulated amortization and impairment losses (if any). Intangible assets are amortized over their estimated useful lives. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of the reporting period. The Group estimates the recoverable value of its intangible assets. When the carrying amount of an intangible asset exceeds its estimated recoverable amount, the asset is written down to its estimated recoverable amount.

Intangible assets except goodwill, are amortized using the straight-line method, based on the estimated useful lives of the intangible assets as follows:

Years
Software 3-6
License 3-20
Other intangible assets 3-30

Intangible assets are derecognized on disposal, or when no further economic benefits are  expected, either from further use or from disposal. The difference between the carrying amount  and the net proceeds received from disposal is recognized in the consolidated statements of profit or loss and other comprehensive income.

j. Property and equipment

Property and equipment are stated at cost less accumulated depreciation, and impairment losses (if any).

The cost of an item of property and equipment includes: (a) purchase price; (b) any costs directly attributable to bringing the asset to its location and condition; and (c) the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located. Each part of an item of property and equipment with a cost that is significant in relation to the total cost of the item is depreciated separately.

Property and equipment, except land rights, are depreciated using the straight-line method based on the estimated useful lives of the assets as follows:

Years
Buildings 10-50
Leasehold improvements 3-10
Switching equipment 3-15
Telegraph, telex, and data communication equipment 15
Transmission installation and equipment 3-40
Satellite, earth station, and equipment 4-20

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

j. Property and equipment (continued)

Significant expenditures related to leasehold improvements are capitalized and depreciated over the lease term.

The depreciation method, useful life, and residual value of an asset are reviewed at least at each financial year-end and adjusted, if appropriate. The residual value of an asset is the estimated amount that the Group would currently obtain from disposal of the asset, after deducting the estimated costs of disposal, if the asset is already of the age and in the condition expected at the end of its useful life.

Property and equipment acquired in exchange for a non-monetary asset or for a combination of monetary and non-monetary assets are measured at fair value unless, (i) the exchange transaction lacks commercial substance; or (ii) the fair value of neither the asset received, nor the asset given up is measured reliably.

Major spare parts and standby equipment that are expected to be used for more than 12 months are recorded as part of property and equipment.

When assets are retired or otherwise disposed of, their cost and the related accumulated depreciation are derecognized from the consolidated statements of financial position and the  resulting gains or losses on the disposal or sale of the property and equipment are recognized in  the consolidated statements of profit or loss and other comprehensive income.

Certain computer hardware cannot be used without the availability of certain computer software.  In such circumstance, the computer software is recorded as part of the computer hardware. If the computer software is independent from its computer hardware, it is recorded as part of intangible assets.

The cost of maintenance and repairs are charged to the consolidated statements of profit or loss and other comprehensive income as incurred. Significant renewals and improvements are capitalized to related property and equipment account.

The Group recognizes the cost of replacing part of a property and equipment in the carrying amount of the property and equipment, and derecognizes the carrying amount of the replaced part of the asset.

Property under construction is stated at cost less impairment (if any), until the construction is completed, at which time it is reclassified to the property and equipment account to which it relates. During the construction period and until the property is ready for its intended use or sale, borrowing costs, which include interest expense and foreign currency exchange differences incurred on loans obtained to finance the construction of the asset, as long as it meets the definition of a qualifying asset are, capitalized in proportion to the average amount of accumulated expenditures during the period. Capitalization of borrowing cost ceases when the construction is completed, and the asset is ready for its intended use or sale.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

k. Leases

The Group assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The lease term corresponds to the non-cancellable period of each contract, except in cases where the Group is reasonably certain of exercising renewal options contractually foreseen.

The Group has made use of the package of practical expedients available within PSAK 116, which among other things:

the use of a single discount rate to a portfolio of leases with reasonably similar characteristics;
the accounting for operating leases with a remaining lease term of less than 12 months as short-term leases;
--- ---
the exemption of initial direct costs for the measurement of the right-of-use asset (“ROU”) as short-term leases;
--- ---
the use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease;
--- ---
not separating non-lease components from lease components, and instead, account for both as a single lease component; and
--- ---
not recognizing a lease liability and a ROU asset for leases where the underlying assets are low-value assets (i.e. underlying assets with a maximum value of US$5,000 or Rp50 million when it is new).
--- ---

The Group applies the definition of a lease and related guidance set out in PSAK 116 to all lease contracts.

i. The Group as lessee

The Group applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Group recognizes lease liabilities to make lease payments and ROU assets representing the right to use the underlying assets.

The Group recognizes ROU assets at the commencement date of the lease. ROU assets are measured at cost, less any accumulated amortization and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of ROU assets includes the amount of lease liabilities recognized, initial direct costs incurred, restoration costs and lease payments made at or before the commencement date less any lease incentives received.

ROU assets are amortized on a straight-line basis over the shorter of the lease term and the estimated useful lives of the assets, as follows:

Years
Land rights 1-33
Buildings 1-30
Transmission installation and equipment 1-25
Vehicles 1-6
Others 1-6

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

k. Leases (continued)

i. The Group as lessee (continued)

If ownership of the ROU asset transfers to the Group at the end of the lease term or the cost reflects the exercise of a purchase option, depreciation is calculated using the estimated  useful life of the asset. The ROU assets are subject to impairment in accordance with  PSAK 236: Impairment of Assets.

Lease liabilities

At the commencement date of the lease, the Group recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group and payments of penalties for terminating the lease, if the lease term reflects the Group exercising the option to terminate. Variable lease payments that do not depend on an index or a rate are recognized as expenses in the period in which the event or condition that triggers the payment occurs.

In calculating the present value of lease payments, the Group uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the lease payments, or a change in the assessment of an option to purchase the underlying asset.

Short-term leases with a duration of less than 12 months and low-value assets leases, as well as those lease elements, partially or totally not complying with the principles of recognition defined by PSAK 116 will be treated similarly to operating leases. The Group will recognize those lease payments on a straight-line basis over the lease term in the consolidated statements of profit or loss and other comprehensive income.

ii. The Group as lessor

Under PSAK 116, a lessor continues to classify leases as either finance leases or operating leases and account for those two types of leases differently. Leases in which the Group transfers substantially all the risks and rewards incidental to ownership of an asset are classified as finance leases, otherwise it will be classified as operating leases. Lease classification is made at the inception date and is reassessed only if there is a lease modification.

At the commencement date, the Group recognizes assets held under a finance lease at an amount equal to the net investment in the lease and present it as finance lease receivable. The net investment in the lease includes fixed payments (including in substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and residual value guarantees provided to the lessor by the lessee. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the lessee and payments of penalties for terminating the lease, if the lease term reflects the Group exercising the option to terminate.

k. Leases (continued)

ii. The Group as lessor (continued)

As required by PSAK 109, an allowance for expected credit loss has been recognized on the finance lease receivables and presented under “Other receivables” (Note 8).

Rental income arising from operating leases is accounted for on a straight-line basis over the lease terms and is included in revenue in the consolidated statements of profit or loss and other comprehensive income due to its operating nature. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the underlying asset and recognized over the lease term on the same basis as rental income. Contingent rents are recognized as revenue in the period in which they are earned.

If an arrangement contains lease and non-lease components, the Group applies PSAK 115 Revenue from Contracts with Customers to allocate the consideration in the contract. Revenue arising from operating lease is recorded as revenue from lessor transactions (Note 2o).

l. Deferred charges - land rights

Costs incurred to process the initial legal land rights are recognized as part of the property and equipment and are not amortized. Costs incurred to process the extension or renewal of legal land rights are deferred and amortized using the straight-line method over the shorter of the legal term of the land rights or the economic life of the land.

m. Borrowings

Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently carried at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the consolidated statements of profit or loss and other comprehensive income over the period of the borrowings using the effective interest method.

Fees paid on obtaining loan facilities are recognized as transaction costs of the loan to the extent that it is probable that some or all of the facilities will be drawn down. In this case, the fee is deferred until the drawdown occurs. To the extent there is no evidence that it is probable that some or all of the facilities will be drawn down, the fee is capitalized as a prepayment for liquidity services and amortized over the period of the facilities to which it relates.

The result of foreign exchange gains or losses, realized and unrealized, are credited or charged to the consolidated statements of profit or loss and other comprehensive income of the current year, except for foreign exchange differences incurred on borrowings during the construction of qualifying assets which are capitalized to the extent that the borrowings can be attributed to the construction of those qualifying assets (Note 2i).

o. Revenue and expense recognition

Revenue from contract with customers

PSAK 115 establishes a comprehensive framework to determine how, when, and how much revenue is to be recognized. The standard provides a single principles-based five-step model for the determination and recognition of revenue to be applied to all contracts with customers. The standard also provides specific guidance requiring certain types of costs to obtain and/or fulfill a contract to be capitalized and amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the capitalized cost relates.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

o. Revenue and expense recognition (continued)

Revenue from contract with customers (continued)

Below is the summary of the Group’s revenue recognition accounting policy for each revenue stream:

i. Data, Internet and IT Service

Revenues from data communication and internet are recognized based on service activity and performance which are measured by the duration of internet usage or based on the fixed amount of charges depending on the arrangements with customers. Revenues from sales, installation and implementation of computer software and hardware, computer data network installation service and installation are recognized when the goods and/or services are delivered to customers or the installation takes place. Revenue from computer software development service is recognized using the percentage-of completion method.

For services sold in bundled plan/solution, total consideration is allocated to performance obligations based on stand-alone selling price for each of the product and/or service.  The Group estimates the stand-alone selling price using the price enacted if the services are sold on a stand-alone basis. Most bundled plans/solution sold by the Group only include services which are generally satisfied over the same period of time. Therefore, the revenue recognition pattern is generally not impacted by the allocation.

ii. IndiHome

Revenues from IndiHome service are derived from customer who subscribes to internet services or to bundled package with combination of consumer service (i.e. telephone, internet and data, and paid TV). Those services are offered on a postpaid basis and billed in the following month. The Group applies terms and conditions that requires the customer to pay substantive early termination penalty if the customer’s contract is ended at the customer’s request and/or fault within the first 12 months after the service is activated. After the initial  12-month period, the customer can decide to stop subscribing in accordance with the applicable terms and conditions without incurring any penalties. In accordance with PSAK 115, the contract period is 12 months, which is then followed by a monthly contract.

All IndiHome services are recognized using the output method based on the customer's actual usage or time elapsed basis as the customer simultaneously receives and consumes the benefits provided by the Group.

Customers are required to pay an upfront fee at the commencement of the contract. The upfront fee is considered to be a material right because the customer is not required to pay an upfront fee when the customer renews the service beyond the original contract period. The Group values the renewal option in the amount of the consideration received from the upfront fee for the installation service. The Group defers the amount of renewal option as contract liabilities and recognizes it as revenue on a straight-line basis over the expected customer life. The Group estimates the expected customer life based on the historical information and customer trends and updates the evaluation on an annual basis.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

o. Revenue and expense recognition (continued)

Revenue from contract with customers (continued)

iii. Interconnection

Revenue from interconnection is mainly comprises of interconnections service or other telecommunications carriers’ subscriber calls to the Group’s subscribers (incoming call),  calls between other telecommunications carriers’ subscribers through the Group’s network (transit), and network service with other telecommunications carriers. All of these services are recognized based on the output method using the basis of the actual recorded traffic for the month.

iv. SMS, Fixed and Cellular Voice

Services are offered on postpaid or prepaid basis. For prepaid services, initial package sales (also known as SIM cards and initial charging vouchers) and top-up vouchers are initially recognized as contract liabilities. The Group recognizes contract assets for the services from postpaid customers that have not been billed.

Those services revenues are recognized based on output method, either per actual usage or allowance unit used (if the services are sold in plan basis), because the customer simultaneously receives and consumes the benefits provided by the Group.

For services sold in bundled plan, total consideration is allocated to performance obligations based on stand-alone selling price for each of the product and/or service. The Group estimates the stand-alone selling price using the price enacted if the services are sold on a stand-alone basis. Most bundled plans sold by the Group only include services which are generally satisfied over the same period of time. Therefore, the revenue recognition pattern is generally not impacted by the allocation.

The consideration that is received is allocated between the telecommunication services sold and the points issued, with the consideration allocated to points that are equal to its fair value. The fair value of the points that are issued is deferred and recognized as revenue when the points are redeemed, expired, or when the program is terminated.

v. Network and Other Telecommunication Services

Revenues from network consist of revenues from leased lines and satellite transponder leases which are recognized over the period in which the services are rendered. Revenues from other telecommunications equipments or services are recognized when other telecommunications equipments or services are rendered to customers.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

o. Revenue and expense recognition (continued)

Contract assets

A contract asset is initially recognized for revenue earned from delivery of goods or services because the receipt of consideration is conditional on certain milestones or upon completion of the project. Upon completion of the milestones or the project, the amount recognized as contract assets is reclassified to trade receivables.

Refer to accounting policies on impairment of financial assets in section 2.r.i. Financial  instruments - initial recognition and subsequent measurement.

Contract liabilities

A contract liability is recognized if a payment is received or a payment is due (whichever is earlier) from a customer before the Group transfers the related goods or services. Contract liabilities are recognized as revenue when the Group performs under the contract (i.e., transfers control of the related goods or services to the customer).

Incremental cost of obtaining and cost of fulfilling contract

The incremental costs of obtaining/fulfilling contracts with customers, which principally are comprised of sales commissions and contract fulfilment costs, are initially recognized on the consolidated statements of financial position as contract costs. These costs are subsequently amortized on a systematic basis that is consistent with the period and pattern of transfer to the customer of the related products or services. Costs that do not qualify as costs of obtaining/fulfilling contract with customers are expensed as incurred or in accordance with other relevant standards.

At the end of each reporting year, the Group evaluates whether there is an indication that capitalized contract costs may be impaired. An impairment exists when the carrying amount of the contract costs exceeds the amount expected to be received in exchange for goods and services. When impairment exists, an impairment loss is recognized in consolidated statements of profit or loss and other comprehensive income.

Revenue from lessor transactions

Revenue from lessor transactions comprises of revenue from telecommunication tower operating leases and other rental. Rental income is recognized on a straight-line basis over the lease term and is included in revenue in the statements of profit or loss due to its operating nature.

Expenses

Expenses are recognized as they are incurred.

p. Employee benefits

i. Short-term employee benefits

All short-term employee benefits which consist of salaries and related benefits, vacation pay, incentives and other short-term benefits are recognized as expense on undiscounted basis when employees have rendered service to the Group.

ii. Post-employment benefit plans and other long-term employee benefits

Post-employment benefit plans consist of funded and unfunded defined benefit pension plans, defined contribution pension plan, other post-employment benefits, post-employment health care benefit plan, defined contribution health care benefit plan and obligations under the Labor Law.

Other long-term employee benefits consist of Long Service Awards (“LSA”), Long Service Leave (“LSL”), and pre-retirement benefits.

The cost of providing benefits under post-employment benefit plans and other long-term employee benefits calculation is performed by an independent actuary using the projected unit credit method.

The net obligations in respect of the defined pension benefit plans and post-retirement health care benefit plan are calculated at the present value of estimated future benefits that the employees have earned in return for their service in the current and prior periods less the fair value of plan assets. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of Government bonds that are denominated in the currencies in which the benefits will be paid and that have terms to maturity approximating the terms of the related retirement benefit obligation. Government bonds are used as there are no deep markets for high quality corporate bonds.

Plan assets are assets owned by defined benefit pension plan and post-retirement health care benefits plan as well as qualifying insurance policy. The assets are measured at fair value as of reporting dates. The fair value of qualifying insurance policy is deemed to be the present value of the related obligations (subject to any reduction required if the amounts receivable under the insurance policies are not recoverable in full).

Remeasurement, comprising of actuarial gains and losses, the effect of the asset ceiling (excluding amounts included in net interest on the net defined benefit liability (asset) and the return on plan assets (excluding amounts included in net interest on the net defined benefit liability (asset)) are recognized immediately in the consolidated statements of financial position with a corresponding debit or credit to retained earnings through OCI in the period in which they occur. Remeasurements are not reclassified to profit or loss in subsequent periods.

Past service costs are recognized immediately in profit or loss on the earlier of:

(a) the date of plan amendment or curtailment; and
(b) the date that the Group recognized restructuring-related costs.
--- ---

Net interest is calculated by applying the discount rate to the net defined benefit liabilities or assets.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

p. Employee benefits (continued)

ii. Post-employment benefit plans and other long-term employee benefits (continued)

Gains or losses on curtailment are recognized when there is a commitment to make a material reduction in the number of employees covered by a plan or when there is an amendment of defined benefit plan terms such as that a material element of future services to be provided by current employees will no longer qualify for benefits, or will qualify only for reduced benefits.

Gains or losses on settlement are recognized when there is a transaction that eliminates all further legal or constructive obligation for part, or all of the benefits provided under a defined benefit plan **** (other than the payment of benefit in accordance with the program and included in the actuarial assumptions).

For defined contribution plans, the regular contributions constitute net periodic costs for the period in which they are due and, as such, are included in “personnel expenses” as they become payable.

The Group attributed benefits under the defined benefit plan’s benefit formula to periods of service from the date when employee service first leads to benefits under the plan until the date when further employee service will lead to no material amount of further benefits under the plan.

iii. Early retirement benefit

Early retirement benefits are accrued at the time the Group makes a commitment to provide early retirement benefits as a result of an offer made in order to encourage voluntary resignation. A commitment to a termination arises when, and only when a detailed formal plan for the early retirement cannot be withdrawn.

q. Taxes

Income tax

Current and deferred income taxes are recognized as income or expense and included in the consolidated statements of profit or loss and other comprehensive income, except to the extent that the income tax arises from a transaction or event which is recognized directly in equity, in which case, the income tax is recognized directly in equity.

Current income tax assets and liabilities are measured at the amounts expected to be recovered or paid by using the tax rates and tax laws that have been enacted or substantively enacted at each reporting date. Management periodically evaluates positions taken in Annual Tax Returns ("Surat Pemberitahuan Tahunan"/"SPT Tahunan") with respect to situations in which applicable tax regulation is subject to interpretation. Where appropriate, management establishes provisions based on the amounts expected to be paid to the Tax Authorities.

Tax assessments

Amendment to taxation obligation is recorded when an assessment letter (“Surat Ketetapan Pajak” or “SKP”) is received or, if appealed against, when the results of the appeal have been determined. The additional taxes and penalty imposed through SKP are recognized as revenue or expense in the current year profit or loss, unless objection/appeal is taken. The additional taxes and penalty imposed through SKP are deferred as long as they meet the asset recognition criteria.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

q. Taxes (continued)

Deferred tax

The Group recognizes deferred tax assets and liabilities for temporary differences between the financial and tax bases of assets and liabilities at each reporting date. The Group also recognizes deferred tax assets resulting from the recognition of future tax benefits, such as the benefit of tax losses carried forward to the extent their future realization is probable. Deferred tax assets and liabilities are measured using enacted or substantively enacted tax rates and tax laws at each reporting date which are expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced if it is no longer probable that sufficient taxable profit will be available to compensate part, or all of the benefits of deferred tax assets. Unrecognized deferred tax assets are re-assessed at each reporting date and recognized if it is probable that future taxable profits will be available for recovery. Tax deductions arising from the reversal of deferred tax assets are excluded from estimates of future taxable income.

Deferred tax transactions which are recognized outside profit or loss. Therefore, deferred taxes on these transactions are recognized either in other comprehensive income or recognized directly in equity.

Deferred tax assets and liabilities are offset in the consolidated statements of financial position, if and only if it has a legally enforceable right to set off current tax assets and liabilities and the deferred tax assets and liabilities relate to income taxes levied by the same Tax Authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax assets or liabilities are expected to be recovered or settled.

Value added tax (“VAT”)

Revenues, expenses and assets are recognized net of the VAT amount except:

i. VAT arising from the purchase of assets or services that cannot be credited by the Tax Office, which VAT is recognized as part of the acquisition cost of the asset or as part of the applied expenses; and
ii. Receivables and payables are presented including the amount of VAT.
--- ---

Uncertainty over income tax treatments

ISAK 123: Uncertainty Over Income Tax Treatments stated that the recognition and measurement of tax assets and liabilities that contain uncertainty over income tax are determined by considering whether to be treated separately or together, the assumptions used in the examination of tax treatments by the Tax Authorities, consideration the probability that the Tax Authorities will accept uncertain tax treatment and re-consideration or estimation if there is a change in facts and circumstances.

If the acceptance of the tax treatment by the Tax Authorities is probable, the measurement is in line with income tax fillings. If the acceptance of the tax treatment by the Tax Authorities is not probable, the Group measures its tax balances using the method that provides the better prediction of resolution (i.e. most likely amount or expected value).

q. Taxes (continued)

Final tax

Indonesian tax regulations impose final tax on several types of transactions based on the gross value of the transaction. Therefore, final tax which is charged based on such transaction remains subject to tax even though the taxpayer incurred a loss on the transaction.

The final tax is scoped out from PSAK 212: Income Tax. Final tax on construction services and leases are presented as part of “Other income - net”.

r. Financial instruments

The Group classifies financial instruments into financial assets and financial liabilities. A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

i. Financial assets

Initial recognition and measurement

Financial assets are classified, at initial recognition, and subsequently measured at amortized cost, fair value through OCI (“FVTOCI”), and fair value through profit or loss (“FVTPL”).

The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Group’s business model for managing them. With the exception of trade receivables that do not contain a significant financing component or for which the Group has applied the practical expedient, the Group initially measures a financial asset at its fair value plus, in the case of a financial asset not at FVTPL, transaction costs. Trade receivables that do not contain a significant financing component or for which the Group  has applied the practical expedient are measured at the transaction price determined under PSAK 115.

In order for a financial asset to be classified and measured at amortized cost or FVTOCI, it needs to give rise to cash flows that are Solely Payments of Principal and Interest (“SPPI”) on the principal amount outstanding. This assessment is referred to as the solely payments of principal and interest test and is performed at an instrument level.

The Group’s business model for managing financial assets refers to how it manages its financial assets in order to generate cash flows. The business model determines whether cash flows will result from collecting contractual cash flows, selling the financial assets, or both.

Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the marketplace (regular way trades) are recognized on the trade date, i.e., the date that the Group commits to sell the asset.

Subsequent measurement

For purposes of subsequent measurement, financial assets are classified in four categories:

(a) Financial assets at amortized cost (debt instruments)

The Group measures financial assets at amortized cost if both of the following conditions are met:

The financial asset is held within a business model with the objective to hold financial assets in order to collect contractual cash flows; and
The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.
--- ---

Financial assets at amortized cost are subsequently measured using the effective interest rate (“EIR”) method and are subject to impairment. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired. The Group’s financial assets at amortized cost consist of cash and cash equivalents, trade and other receivables, other current financial assets, and other non-current assets.

(b) Financial assets at FVTOCI with recycling of cumulative gains and losses (debt instruments)

The Group measures debt instruments at FVTOCI if both of the following conditions are met:

The financial asset is held within a business model with the objective of both holding to collect contractual cash flows and selling; and
The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.
--- ---

For debt instruments at FVTOCI, interest income, foreign exchange revaluation, and impairment losses or reversals are recognized in the statements of profit or loss and computed in the same manner as for financial assets measured at amortized cost. The remaining fair value changes are recognized in OCI. Upon derecognition, the cumulative fair value change recognized in OCI is recycled to profit or loss.

(c) Financial assets designated at FVTOCI with no recycling of cumulative gains and losses upon derecognition (equity instruments)

Upon initial recognition, the Group can elect to classify irrevocably its equity investments as equity instruments designated at FVTOCI when they meet the definition of equity under PSAK 232, Financial Instruments: Presentation and are not held for trading. The classification is determined on an instrument-by-instrument basis. Gains and losses on these financial assets are never recycled to consolidated statements of profit or loss and other comprehensive income. Dividends are recognized as other income in  the statements of profit or loss when the right of payment has been established, except when the Group benefits from such proceeds as a recovery of part of the cost of the financial asset, in which case, such gains are recorded in OCI. Equity instruments designated at FVTOCI are not subject to impairment assessment. The Group’s financial assets at this category consists of long-term investments in financial instruments.

(d) Financial assets at FVTPL

Financial assets at FVTPL include financial assets held for trading, financial assets designated upon initial recognition at FVTPL, or financial assets mandatorily required to be measured at fair value. Financial assets are classified as held for trading if they are acquired for the purpose of selling or repurchasing in the near term. Derivatives, including separated embedded derivatives, are also classified as held for trading unless they are designated as effective hedging instruments. Financial assets with cash flows that do not meet the SPPI requirement are classified and measured at FVTPL, irrespective of the business model. Notwithstanding the criteria for debt instruments to be classified at amortized cost or at FVTOCI, as described above, debt instruments may be designated at FVTPL on initial recognition if doing so eliminates, or significantly reduces, an accounting mismatch.

Financial assets at FVTPL are carried in the consolidated statements of financial position at fair value with net changes in fair value recognized in the consolidated statements of profit or loss and other comprehensive income. The Group’s financial assets at FVTPL consists of other long-term investments in financial instruments and other current financial assets.

Expected credit losses (“ECL”)

The Group recognizes an allowance for ECL for all debt instruments not held at FVTPL. ECL are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Group expects to receive, discounted at  an approximation of the original effective interest rate. The expected cash flows will include cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms.

ECL are recognized in two stages. For credit exposures for which there has not been  a significant increase in credit risk since initial recognition, ECL are provided for credit losses that result from default events that are possible within the next 12-months (a 12-month ECL). For those credit exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit losses expected over the remaining life of the exposure, irrespective of the timing of the default (a lifetime ECL).

For trade receivables and contract assets, the Group applies a simplified approach in calculating ECL. Therefore, the Group does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime ECL at each reporting date. The Group has established an allowance for expected credit loss methodology that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment.

Expected credit losses (“ECL”) (continued)

The Group considers a financial asset in default when contractual payments are 90 days past due. However, in certain cases, the Group may also consider a financial asset to be in default when internal or external information indicates that the Group is unlikely to receive the outstanding contractual amounts in full before taking into account any credit enhancements held by the Group. Trade receivables are written-off when there is a low possibility of recovering the contractual cash flow, after all collection efforts have been done and have been fully provided for allowance.

ii. Financial liabilities

Initial recognition and measurement

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loan and borrowings and payables, net of directly attributable transaction costs.

The Group classifies its financial liabilities as: (a) financial liabilities at FVTPL or (b) financial liabilities measured at amortized costs.

The Group’s financial liabilities include trade and other payables, accrued expenses, customer deposits, interest-bearing loans, and lease liabilities. Interest-bearing loans consist of short-term bank loans, bonds, and long-term bank loans.

Subsequent measurement

The measurement of financial liabilities depends on their classification, as described below:

(a) Financial liabilities at FVTPL

Financial liabilities at FVTPL include financial liabilities held for trading and financial liabilities designated upon initial recognition as at FVTPL. Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Group that are not designated as hedging instruments in hedge relationships. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments. Gains or losses on liabilities held for trading are recognized in the statements of profit or loss.

Financial liabilities designated upon initial recognition at FVTPL are designated at the initial date of recognition, and only if the criteria in PSAK 109 are satisfied. The Group has not designated any financial liability as at FVTPL.

Subsequent measurement (continued)

(b) Financial liabilities measured at amortized cost

This is the category most relevant to the Group. After initial recognition, interest-bearing loans and other borrowings are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the statements of profit or loss. This category generally applies to interest-bearing loans and other borrowings. For more information, refer to Note 19.

iii. Offsetting financial instruments

Financial assets and liabilities are offset and the net amount is reported in the consolidated statements of financial position when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle them on a net basis, or realize the assets and settle the liabilities simultaneously. The right of offset must not be contingent on a future event and must be legally enforceable in all of the following circumstances:

(a) the normal course of business;
(b) the event of default; and
--- ---
(c) the event of insolvency or bankruptcy of the Group and all of the counterparties.
--- ---

iv. Derecognition of financial instruments

The Group derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire, or when the Group transfers substantially all the risks and rewards of ownership of the financial asset.

The Group derecognizes a financial liability when the obligation specified in the contract is discharged or cancelled or has expired.

s. Treasury stock

Reacquired the Company’s shares of stock are accounted for at their reacquisition cost and classified as “Treasury Stock” and presented as a deduction in equity. The cost of treasury stock sold/transferred is accounted for using the weighted average method. No gain or loss is recognized in profit or loss on the acquisition, resale, issuance, or cancellation of the Group’s equity instruments. Any difference between the carrying amount and consideration from future re-sale of treasury stocks, is recognized as part of additional paid-in-capital in the equity.

t. Dividends

Dividend for distribution to the stockholders is recognized as a liability in the consolidated financial statements in the year in which the dividend is approved by the stockholders. The interim dividend is recognized as a liability based on the Directors’ decision supported by the approval from the Board of Commissioners.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

u. Basic earnings per share and earnings per ADS

Basic earnings per share is computed by dividing profit for the year attributable to owners of the parent company by the weighted average number of shares outstanding during the year. Income per ADS is computed by multiplying the basic earnings per share by 100, the number of shares represented by each ADS.

v. Segment information

The Group's segment information is presented based upon identified operating segments in accordance with PSAK 108: Operating Segment. An operating segment is a component of an entity:

i. that engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses relating to transactions with other components of the same entity);
ii. whose operating results are regularly reviewed by the Group’s Chief Operating Decision Maker (“CODM”) i.e., the Directors, to make decisions about resources to be allocated to the segment and assess its performance; and
--- ---
iii. for which discrete financial information is available.
--- ---

w. Provisions

Provisions are recognized when the Group has present obligations (legal or constructive) arising from past events and it is probable that an outflow of resources embodying economic benefits will be required to settle the obligations and the amount can be measured reliably.

Provisions for onerous contracts are recognized when the contract becomes onerous for the lower of the cost of fulfilling the contract and any compensation or penalties arising from failure to fulfill the contract.

x. Impairment of non-financial assets

At the end of each reporting period, the Group assesses whether there is an indication that an non-financial assets may be impaired. These assets include property and equipment, current assets, and other non-current assets, including intangible assets. If such indication exists, the recoverable amount is estimated for the individual asset. If it is not possible to estimate the recoverable amount of the individual asset, the Group determines the recoverable amount of the Cash-Generating Unit (“CGU”) to which the asset belongs (“the asset’s CGU”).

The recoverable amount of an asset (either individual asset or CGU) is the higher of the asset’s fair value less costs to sell and its value in use (“VIU”). Where the carrying amount of the asset exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. In assessing the value in use, the estimated net future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset.

In determining fair value less costs to sell, recent market transaction prices are taken into account, if available. If no such transactions can be identified, the Group uses an appropriate valuation model to determine the fair value of the asset. These calculations are corroborated by multiple valuations or other available fair value indicators.

Impairment losses of continuing operations are recognized in the consolidated statements of profit or loss and other comprehensive income.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

x. Impairment of non-financial assets (continued)

At the end of each reporting period, the Group assesses whether there is any indication that previously recognized impairment losses for an asset, other than goodwill, may no longer exist or may have decreased. If such indication exists, the recoverable amount is estimated. A previously recognized impairment loss for an asset, other than goodwill, is reversed only if there has been  a change in the assumptions used to determine the asset’s recoverable amount since the last impairment loss was recognized. The reversal is limited such that the carrying amount of the asset does not exceed its recoverable amount, nor exceeds the carrying amount that would have been determined, net of depreciation, had no impairment been recognized for the asset in prior periods. Reversal of an impairment loss is recognized in consolidated statements of profit or loss and other comprehensive income.

Goodwill is tested for impairment annually and when circumstances indicate that the carrying value may be impaired. Impairment is determined for goodwill by assessing the recoverable amount of each CGU (or group of CGUs) to which the goodwill relates. When the recoverable amount of the CGU is less than its carrying amount, an impairment loss is recognized. Impairment loss relating to goodwill cannot be reversed in future periods.

y. Current and non-current classifications

The Group presents assets and liabilities in the statements of financial position based on current/ non-current classification. An asset is presented as current when it is:

i. expected to be realized or intended to be sold, or consumed in the normal operating cycle;
ii. held primarily for the purpose of trading;
--- ---
iii. expected to be realized within twelve months after the reporting period; or
--- ---
iv. cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period.
--- ---

Assets which do not meet above criteria are classified as non-current assets.

A liability is presented as current when:

i. it is expected to be settled in the normal operating cycle;
ii. it is held primarily for the purpose of trading;
--- ---
iii. it is due to be settled within twelve months after reporting period;
--- ---
iv. there is no right by the end of reporting period to defer the settlement of the liability for at least twelve months after the reporting period.
--- ---

The terms of liability that could, at the option of counterparty, result in its settlement by the issue of equity instruments do not affect its classification.

Liabilities which do not meet above criteria are classified as long-term liabilities.

Deferred tax assets and liabilities are classified as non-current assets and liabilities.

z. Significant accounting judgements, estimates, and assumptions

The preparation of the Group's consolidated financial statements requires management to make judgements, estimates, and assumptions that affect the reporting amounts of revenue, expenses, assets and liabilities, and the accompanying disclosures, and disclosures of contingent liabilities, at the end of the reporting period.

Uncertainty about these assumptions and estimates can produce results that require a material adjustment to the carrying amounts of assets and liabilities affected in the coming periods.

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES INFORMATION (continued)

z. Significant accounting judgements, estimates, and assumptions (continued)

i. Judgements

The following judgements were made by management in applying the Group's accounting policies that have the most significant influence on the amounts recognized in the consolidated financial statements:

Segment information

For management purposes, the Group uses a business pillars-based as follows: Business to Customer (“B2C”), Business to Business Infrastructure (“B2B Infra”), Business to  Business ICT (“B2B ICT”), International, and Others. The Group has determined the reportable segment reported based on, among others, the structure of the organization as well as the components of the Group whose operating results are regularly reviewed by CODM. The Group has determined that the Directors is the CODM, as it monitors the operating results of each segment separately for the purposes of resource allocation and performance assessment.

Income taxes

Uncertainties exist with respect to the interpretation of complex tax regulations, changes in tax laws, and the amount and timing of future taxable income could necessitate future adjustments to tax income and expense already recorded. Judgement is also involved in determining the provision for corporate income tax. There are certain transactions and computation for which the ultimate tax determination is uncertain during the ordinary course of business.

The Group recognizes liabilities for anticipated tax audit issues based on estimates of whether additional taxes will be due. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the current and deferred income tax assets and liabilities in the year in which such determination is made.

ii. Estimates and assumptions

Estimates and assumption are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions at the reporting date that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are addressed below.

(a) Retirement benefits

The present value of the retirement benefit obligations depends on a number of factors that are determined on an actuarial basis using a number of assumptions. The assumptions used in determining the net cost (income) for pensions include the discount rate and return on investment (“ROI”). Any changes in these assumptions will impact the carrying amount of the retirement benefit obligations.

The Group determines the appropriate discount rate at the end of each reporting period. This is the interest rate that should be used to determine the present value of estimated future cash outflows expected to be required to settle the obligations. In determining the appropriate discount rate, the Group considers the interest rates of Government bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related retirement benefit obligations.

z. Significant accounting judgements, estimates, and assumptions (continued)

ii. Estimates and assumptions (continued)

(a) Retirement benefits (continued)

If there is an improvement in the ratings of such Government bonds or a decrease in interest rates as a result of improving economic conditions, there could be a material impact on the discount rate used in determining the post-employment benefit obligations.

Other key assumptions for retirement benefit obligations are based in part on current market conditions. Additional information is disclosed in Notes 30 and 31.

(b) Useful lives of property and equipment

The Group estimates the useful lives of its property and equipment based on expected asset utilization, considering strategic business plans, expected future technological developments, and market behavior. The estimates of useful lives of property and equipment are based on the Group’s collective assessment of industry practice, internal technical evaluation, and experience with similar assets.

The Group reviews its estimates of useful lives at least each financial year-end and such estimates are updated if expectations differ from previous estimates due to changes in expectation of physical wear and tear, technical or commercial obsolescence, and legal or other limitations on the continuing use of the assets. The amounts of recorded expenses for any year will be affected by changes in these factors and circumstances. A change in the estimated useful lives of the property and equipment is a change in accounting estimates and is applied prospectively in profit or loss in the period of the change and future periods.

In 2025, the Company determined changes in the estimated useful lives for several assets owned by the Company are as follows:

Estimated Change in estimated
useful lives useful lives
Property and equipment Asset class (years) (years)
Cable network Optical line terminal 25 8
Switching equipment Switching equipment 10-15 5-10
Transmission installation,
and equipment Terrestrial transmission 10-15 8
Satellite, earth station,<br><br>and equipment IP Multimedia Subsystem<br><br>("IMS") 10-15 8

(c) Determining the lease term of contracts with renewal and termination options - Group as lessee

The Group determines the lease term as the non-cancellable term of the lease, together with any periods covered by an option to extend the lease if it is reasonably certain to be exercised, or any periods covered by an option to terminate the lease, if it is reasonably certain not to be exercised.

ii. Estimates and assumptions (continued)

(c) Determining the lease term of contracts with renewal and termination options - Group as lessee (continued)

The Group has several lease contracts that include extension and termination options. The Group applies judgement in evaluating whether it is reasonably certain whether or not to exercise the option to renew or terminate the lease. That is, it considers all relevant factors that create an economic incentive for it to exercise either the renewal or termination. After the commencement date, the Group reassesses the lease term if there is a significant event or change in circumstances that is within its control and affects its ability to exercise or not to exercise the option to renew or to terminate.

(d) Allowance for expected credit losses for financial assets

The Group applies a simplified approach in calculating ECLs for trade receivables and contract assets. Therefore, the Group does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime ECLs at each reporting date. For other receivables, the Group assesses whether there is objective evidence that other receivables have been impaired at the end of each reporting period.

The Group has established an allowance for expected credit losses methodology for trade receivables and contract assets that is based on its historical credit loss experience and latest supportable data to better reflect the current change in circumstances, adjusted for forward-looking factors specific to the debtors, and the economic environment. Methods and approaches will continue to be monitored and updated if additional reasonable and supportable data and information are available.

(e) Revenue

(i) Critical judgements in determining the performance obligation, timing of revenue recognition, and revenue classification

The Group provides information technology services that are bespoke in nature. Bespoke products consist of various goods and/or services bundled together in order to provide integrated solution services to customers. In addition to the bespoke service, the Group also provides multiple standard products as bundling product in contract with customer. Significant judgement is required in determining the number and nature of performance obligations promised to customers in those contracts. The number and nature of performance obligations will determine the timing of revenue recognition for such contract.

The Group reviews the determination of performance obligations on a contract-by-contract basis. When a contract consisting of several goods and/or service is assessed to have one performance obligation, the Group applies a single method of measuring progress for the performance obligation based on the measurement method that best depicts the economics of the contract, which in most cases is over time.

The Group also presents the revenue classification using consistent approach. When a contract consisting of several goods and/or service is assessed to have one performance obligation, the Group presents that performance obligations in one financial statement line items which best represent the main service of the Group, which in most cases is the internet, data communication, and information technology services.

(e) Revenue (continued)

(ii) Critical judgements in determining the stand-alone selling price

The Group provides wide array of products related to telecommunication and technology. To determine the stand-alone selling price for goods and/or services that do not have any readily available observable price, the Group uses the expected cost-plus margin approach. The Group determines the appropriate margin based on historical achievement.

(f) Test for impairment of non-current assets and goodwill

The application of the acquisition method in a business combination requires the use of accounting estimates in allocating the purchase price to the fair market value of the assets and liabilities acquired, including intangible assets. Certain business acquisitions by the Group resulted goodwill, which is not amortized but is tested for impairment annually and every indication of impairment exists.

The calculation of future cash flows in determining the fair value of property and equipment and other non-current assets of the acquired entity at the acquisition date involves significant estimation. Although management believes that the assumptions used are appropriate, significant changes to those assumptions can materially affect the evaluation of recoverable amounts and may result in impairment according to PSAK 236.

(g) Fair value measurement of financial instruments

When the fair values of financial assets and financial liabilities recorded in the statements of financial position cannot be measured based on quoted prices in active markets, their fair value is measured using valuation techniques including the discounted cash flow (“DCF”) model. The inputs to these models are taken from observable markets where possible, but where this is not feasible, a degree of judgement is required in establishing fair values. Judgements include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions relating to these factors could affect the reported fair value of financial instruments.

(h) Acquisition

The Group evaluates each acquisition transaction to determine whether it will be treated as an asset acquisition or business combination. For transactions that are treated as an asset acquisition, the purchase price is allocated to the assets obtained, without the recognition of goodwill. For acquisitions that meet the business combination definition, the Group applies the accounting for business acquisiton method for assets acquired and liabilities assumed which are recorded at fair value at the acquisition date, and the results of operations are included with the Group's results from the date of each acquisition.

(h) Acquisition (continued)

Any excess from the purchase price paid for the amount recognized for assets acquired and liabilities incurred is recorded as goodwill. The Group continues to evaluate acquisitions that are counted as a business combination for a period not exceeding one year after the applicable acquisition date of each transaction to determine whether additional adjustments are needed to allocate the purchase price paid for the assets acquired and liabilities assumed. The fair value of assets acquired and liabilities incurred are usually determined using either an estimated replacement cost or a discounted cash flow valuation method. When determining the fair value of tangible assets acquired, the Group estimates the cost of replacing assets with new assets by considering factors such as the age, condition, and economic useful lives of the assets. When determining the fair value of the intangible assets obtained, the Group estimates the applicable discount rate and the time and amount of future cash flows, including the rates and terms for the extension and reduction.

iii. Restatement of Consolidated Financial Statements

In 2025, following a detailed reassessment of the physical characteristics, operational deployment, and asset topology of drop cable, the Group concluded that drop cable should be identified and classified as a separate component of telecommunication infrastructure assets rather than remaining embedded within broader shared access-network cable component. In reaching this conclusion, the Group determined that the revised componentization policy provides more reliable and more relevant information as it better reflects drop cable’s distinct nature as a last-mile, customer-specific connection asset.

This change constitutes a change in accounting policy as it reflects a revision in the principles applied in determining the unit of account and asset classification. Following the identification of drop cable assets as a separate component, the Group determined a useful life of 5 years, reflecting their specific characteristics and pattern of economic benefits consumption.

The Group applied this voluntary change in accounting policy retrospectively, in accordance with PSAK 208. The Group determined that sufficient and reliable information is available to restate prior period comparative information. The consolidated financial statements for the year ended December 31, 2025 include the restatement of comparative information for the years ended December 31, 2024 and January 1, 2024, which affects the consolidated statements of financial position, consolidated statements of profit or loss and other comprehensive income, consolidated statements of changes in equity, and related notes. The cumulative effect for periods prior to January 1, 2024 has been recognized as an adjustment to retained earnings as of that date. There is no impact on the Group’s consolidated statements of cash flows.

Realization of the deferred tax assets is dependent upon the Group’s capability in generating future profitable operations. Although realization is not assured, the Group believes that it is probable that these deferred tax assets will be realized through reduction of future taxable income when temporary differences reverse. The amount of deferred tax assets is considered realizable; however, it can be reduced if actual future taxable income is lower than estimates.

g.Administration

In December 2024, the Government issued Decree of the Minister of Finance Number 465 of 2024 concerning the Implementation of the Core System of Tax Administration and Regulation of the Minister of Finance concerning Tax Provisions in the Framework of Implementing the Core System of Tax Administration No. 81 of 2024. In order to realize the aspect of justice in society, at the end of December 2024 the Government issued Regulation of the Minister of Finance Number 131 of 2024 concerning Value Added Tax Treatment on Imports of Taxable Goods, Delivery of Taxable Goods, Delivery of Taxable Services, Utilization of Intangible Taxable Goods from Outside the Customs Area within the Customs Area, and Utilization of Taxable Services from Outside the Customs Area within the Customs Area (PMK 131/2024) which is effective as of January 1, 2025. PMK 131/2024 regulates that on the Import and/or delivery of Taxable Goods within the Customs Area by Entrepreneurs other than Taxable Goods classified as luxury, delivery of Taxable Services within the Customs Area by Entrepreneurs, utilization of Intangible Taxable Goods from outside the Customs Area within the Customs Area, utilization of Taxable Services from outside the Customs Area within the Customs Area, Tax is payable VAT is calculated by multiplying the 12% (twelve percent) rate by the Taxable Base, which is another value.

The issuance of PMK 131/2024 is in accordance with Law Number 7 of 2021 concerning the Harmonization of Tax Regulations (HPP Law), which stipulates that a VAT rate of 12% will be implemented no later than January 1, 2025. In February 2025, the Government issued Minister of Finance Regulation Number 11 of 2025 concerning Provisions on Other Values as Taxable Bases and Certain Amounts of Value Added Tax. The Company ensures coordination with relevant units, the IT Team and tax authorities to ensure smooth tax administration processes conducted through the Tax Administration Core System application, as well as the provisions for using other values as VAT Taxable Bases.

In response to the implementation of the Organisation for Economic Co-operation and Development (“OECD”) Pillar Two framework, on December 31, 2024, Indonesian Government implemented Pillar Two framework through Regulation of the Minister of Finance No. 136/2024 (PMK 136/2024). The Pillar Two model rules as implemented under PMK 136/2024 which came into effect on January 1, 2025.

PMK 136/2024 applies new taxing mechanisms under which a Multinational Enterprises (“MNE”) would pay a top-up tax in a jurisdiction whenever the effective tax rate, determined on a jurisdictional basis under the Pillar Two rules is below a 15% minimum rate. PMK 136/2024 sets out the mechanics for determining which entity or entities in an MNE Group should apply the top-up tax and the portion of such tax that is charged to each relevant entity.

The Group has conducted an analysis based on applicable tax regulations and identified potential top-up tax for constituent entities operating in the jurisdiction of Timor Leste. The Group believes, based on the results of the analysis, that the impact of these potential top-up tax is not material to the consolidated financial statements for the year ended December 31, 2025.

Risks exposed to defined benefit programs are risks such as asset volatility and changes in bond yields. The project liabilities are calculated using a discount rate that refers to the level of government bond yields, if the return on program assets is lower, it will result in a program deficit. A decrease in the yield of government bonds will increase the program liabilities, although this will be offset in part by an increase in the value of the program bonds held. The Company ensures that the investment position is set within the framework of asset-liability matching ("ALM") that has been formed to achieve long-term results that are in line with the liabilities in the defined benefit pension plan. Within the ALM framework, the Company's objective is to adjust its pension assets and liabilities by investing in a well diversified portfolio to produce an optimal rate of return, taking into account the level of risk. Investment in the program has been well diversified, so that one investment's poor performance will not have a material impact on all asset groups.

As of December 31, 2025 and 2024, plan assets consist of:

(b) Unfunded pension plan

The Company sponsors unfunded defined benefit pension plans and a defined contribution pension plan for its employees. The defined contribution pension plan is provided to employees with permanent status hired on or after July 1, 2002.

MPS is given to those employees reaching retirement age, upon death or upon becoming disabled starting from February 1, 2009.

The Company also provides benefits to employees during a pre-retirement period in which they are inactive for 6 months prior to their normal retirement age of 56 years, known as  pre-retirement benefits (Masa Persiapan Pensiun or “MPP”). During the pre-retirement period, the employees still receive benefits provided to active employees, which include, but are not limited to, regular salary, health care, annual leave, bonus, and other benefits.

ii. Telkomsel

Telkomsel provides a defined benefit pension plan to its employees. Under this plan, employees are entitled to pension benefits determined based on their latest basic salary or take-home pay (exclusive of functional allowances) and number of service years. The plan is managed by  PT Asuransi Jiwasraya (Persero) (“Jiwasraya”), a state-owned life insurance company, through an annuity insurance contract. Until 2004, employees contributed 5% of their monthly salaries to the plan, while Telkomsel contributed the remaining part required under the plan. Beginning in 2005, Telkomsel has been taking responsibility for the full amount of the contributions.

On April 23, 2021, Telkomsel and Jiwasraya agreed to terminate the insurance program contract (as mentioned above) and entered into restructuring agreement. The agreement replaced the benefit plan from annuities to lumpsum benefit. Based on this agreement, both parties agreed to determine the Cash Value (“CV”) at the termination date which divided into CV for active participant and passive participant amounting to Rp857 billion and Rp73 billion, respectively. There was a 5% cut from CV for active participant, hence the 95% of Rp857 billion (or equal to Rp814 billion) plus Rp73 billion will be the amount that subsequently taken over by PT Asuransi Jiwa IFG (“IFG Life”) when the agreement with IFG Life become effective and accordingly, the restructuring agreement will be terminated.

Effective from the business transfer of IndiHome consumer business segment to Telkomsel, Telkomsel sponsors a defined benefit pension plan for transferring employees hired prior to  July 1, 2002. The plan is governed by the pension laws in Indonesia and managed by Dapen. Dapen is managed in accordance with the Pension Fund and Investment Directives Regulations, which is determined by the Company as the Founder and is carried out by the Board of Management. The Board of Management is monitored by the Oversight Board, appointed by the Founder.

The pension benefits are paid based on the participating employee’s latest basic salary at retirement and the number of years of their service. The participating employees contribute 18% of their basic salaries to the pension fund. Telkomsel’s contribution to the pension fund for the year ended December 31, 2025 was amounting to Rp27 billion (2024: Rp18 billion).

The actuarial valuation for the defined benefit pension plan was performed based on the measurement date as of December 31, 2025 and 2024 with reports dated February 13, 2026 and March 6, 2025, respectively, by KKA Halim and Partner, an independent actuary in association with Milliman.

33. OPERATING SEGMENTS

In 2025, Management changed the basis for grouping the Group’s operating segments from a Customer Facing Unit (“CFU”) based approach to a business pillar based approach. This change was made to reflect how CODM reviews the performance of operating segments and allocates resources. In connection with this change, the segment information for the prior year has been restated to conform with the presentation of segment information in the current year.

The Group has identified five reportable segments, namely B2C, B2B Infra, B2B ICT,  International, and Others. There is no aggregation of operating segments in determining these reportable segments. The B2C segment comprises the provision of telecommunications services to individual and residential customers, including mobile and fixed broadband services. The B2B Infra segment comprises the provision, management, and maintenance of telecommunications infrastructure, including telecommunications towers, fiber optic networks, backbone infrastructure, data centers, and satellites. The B2B ICT segment comprises the provision of system integration services, information technology services, and digital solutions to corporate and institutional customers. The International segment comprises the provision of international connectivity and wholesale services to telecommunications operators and customers abroad. The Other segment comprises supporting business activities, including media and content services, business consulting and management services, trading and distribution, certain information technology services, as well as investment and other business development activities.

CODM reviews the performance of each segment based on the segment’s profit or loss, which is measured consistently with operating profit or loss in the consolidated financial statements. Segment revenues and expenses also include intersegment transactions. These transactions are eliminated upon consolidation and are determined based on prevailing market prices (on an arm’s length basis).

In 2008, the Director General of Post and Telecommunication issued Decree No. 115 of 2008 which stated its agreement on Agreement on Network Lease Service Type Document, Network Lease Service Tariff, Available Capacity of Network Lease Service, Quality of Network Lease Service, and Provision Procedure of Network Lease Service Owned by Dominant Network Lease Service Provider in conformity with the Company’s proposal. Through MoCI Regulation No. 5/2021, the Government regulated the form, type, tariff structure, and tariff formula for services of network lease.

e.Tariff for other services

The tariffs for satellite lease, telephony services, and other multimedia are determined by the service provider by taking into account the expenditures and market price. The Government only determines the tariff formula for basic telephony services. There is no stipulation for the tariff of other services.

As result from this agreement, KCIC shall pay to the Company several compensations, which are annual utilization fees totaling Rp878 billion, network recovery fee of Rp1,250 billion, as well as incremental operational and maintenance costs.

(iii) USO

On December 27, 2011, Telkomsel (on behalf of Konsorsium Telkomsel, a consortium which was established with Mitratel on December 9, 2011) was selected by Balai Penyedia dan Pengelola Pembiayaan Telekomunikasi dan Informatika (“BPPPTI”), now has been renamed as Badan Aksesibilitas Telekomunikasi dan Informasi (“BAKTI”) as a provider of the USO Program in the border areas with a total price of Rp261 billion. In 2015, the Program was ceased. In January 2016, Telkomsel filed an arbitration claim to Badan Arbitrase Nasional Indonesia (“BANI”) for the settlement of the outstanding receivables of USO Programs.

On June 22, 2017, Telkomsel received a decision letter from BANI No. 792/1/ARB-BANI/2016 requesting BAKTI to pay compensation to Telkomsel amounting to Rp218 billion, and as of the date of the issuance of these consolidated financial statements Telkomsel has received the payment from BAKTI amounting to Rp91 billion (before tax) and no additional payment.

The MoCD issued Regulation No. 5 Year 2021 dated March 31, 2021, which replaced previous regulations regarding policies underlying the USO program. The regulation requires telecommunications operators in Indonesia to contribute 1.25% of gross revenues (with due consideration for bad debts and/or interconnection charges and/or connection charges and/or the exclusion of certain revenues that are not considered as part of gross revenues as a basis to calculate the USO charged) for USO development.

c. Others (continued)

(iv)Contingency (continued)

In October 2023, the Group received a document request from the U.S. Securities and Exchange Commission (“SEC”) as it relates to Telkom Infra’s involvement in a project with the Indonesian Information and Telecommunication Accessibility Agency of the Ministry of Communication and Informatics (“BAKTI Kominfo”) regarding the provision of 4G Base Transceiver Station (“BTS”) infrastructure. The SEC has since expanded its investigation to include accounting and disclosures issues relating to the Group's revenue recognition and financial reporting practices and internal control over financial reporting, as well as public reports regarding certain Indonesian legal proceedings involving the Group, certain subsidiaries and affiliates, and certain of the Group's clients and suppliers. Through our internal audit process and investigations, we have determined, or we suspect (for those projects and transactions which are still under investigation) that certain transactions lack economic substance. Beginning in May 2024, the Group also received additional requests for information from the U.S. Department of Justice (“DOJ”) focused on compliance with the U.S. Foreign Corrupt Practices Act (“FCPA”). The Group retained outside counsel and a forensic accounting firm to assist with its internal investigation into the issues being investigated by the SEC and DOJ. The Internal Investigation is substantially complete while the SEC and DOJ’s investigations remain ongoing and the Group continues to cooperate with the U.S. authorities.

Based on the results of the Internal Investigation to date, the Group has identified that approximately 140 transactions, primarily those occurring prior to 2021 and particularly between 2016 and 2019 and relate primarily to the enterprise business segment, lacked economic substance and were not in compliance with applicable financial reporting standards as well as the Group’s policies and internal controls, resulting in an overstatement of certain financial information.

The Group does not believe that this overstatement constituted a misstatement that was quantitatively material to the Group’s consolidated financial statements for any period presented in the Group’s prior annual or interim financial statements. The Group believes that these transactions resulted in an overstatement of revenues, gross trade receivables, and net trade receivables, at least as follows:

2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024
Revenues 31 10 291 2,285 721 368 58 378 247 11 39
Trade receivable 23 22 288 1,687 1,972 1,999 2,018 2,154 2,152 2,094 1,927
Trade receivable-net 23 22 256 1,376 1,558 980 94 72 63 63 30

The Group has encountered challenges compiling detailed historical information for  a significant portion of the 140 transactions due to the age of the transactions, accounting system challenges, and challenges related to the retention and retrieval of historical accounting support that in some cases dates back nearly 10 years. The Company has assumed that certain transactions lacked economic substance unless accounting and other supporting information was available to demonstrate otherwise.

By December 31, 2020, the vast majority of the trade receivables associated with these transactions had a full corresponding income statement provision and related allowance for expected credit losses, and therefore the net trade receivable for these transactions reflected on the Company’s Statement of Financial Positions from 2020 onward were de minimis. Accordingly, based on information to date, these historical transactions do not require any corrections to the Statements of Financial Position as of December 31, 2025 and 2024, or  the Statements of Profit or Loss and Other Comprehensive Income for the years ended 2025 and 2024.

35. SIGNIFICANT COMMITMENTS, AGREEMENTS, AND OTHERS (continued)

c. Others (continued)

(iv)Contingency (continued)

The Group determined that Rp1,898 billion and Rp1,762 billion of gross trade receivables, and a corresponding Rp1,898 billion and Rp1,762 billion allowance for expected credit losses related to historical transactions that had been reviewed or were scheduled for review as part of the internal investigation, were reclassified to other non-current assets in the consolidated statements of financial position as of December 31, 2025 and 2024 (Note 13). This reclassification was made to achieve a more appropriate presentation in accordance with the economic substance of the transactions. The Group assessed that these trade receivables did not have a reasonable chance of recovery and therefore no longer met the criteria for presentation as trade receivables. As the reclassified gross receivables and the related allowance for expected credit losses offset each other (net to zero), the reclassification had no impact on the net trade receivables or other non-current assets as of  December 31, 2025 and 2024. Until the date of completion of these consolidated financial statements, these receivables had been approved to be written off based on carrying amount December 31, 2024 in accordance to the applicable regulations, but it is not a waiver of collection right.

The Company is a state-owned enterprise, and accordingly, its receivable write-off process is subject to specific governance and regulatory requirements applicable to state-owned enterprises. Under the applicable write-off policy, receivables exceeding certain thresholds and/or receivables of certain nature require approvals from relevant authorities and/or government bodies. As such, the completion and timing of the write-off process are not solely within Management’s control, as they depend on external review and approval processes involving various governmental stakeholders.

The Group has also cooperated with Indonesian government law enforcement authorities, and has in certain instances self-reported to them various matters involving alleged or potential violations of Indonesian laws and regulations by the Group, certain subsidiaries and affiliates, including anti-corruption, alleged fraud, embezzlement, and issues associated with trade receivables, some of which are related to the above-described matters investigated by the SEC and the DOJ. The Group has implemented various remedial actions, including strengthening policies, procedures, and internal controls, as well as enhancing its compliance function and corporate governance.

For the above mentioned investigation on the Group's accounting and disclosure issues relating to revenue recognition and financial reporting practices and internal control over financial reporting, based on the Group's assessment up to the date of the issuance of the consolidated financial statements, the Group currently does not believe that the above mentioned investigation will have a material adverse effect on its December 31, 2025 and 2024 consolidated financial statements.

As of the issuance date of the consolidated financial statements, the Group is not yet able to reliably estimate the potential loss or range of losses that may arise from the investigations by the SEC and DOJ, due to significant uncertainties regarding the final outcome, timing of resolution, and potential sanctions or other impacts.

In addition, there is a possibility that the final outcome of the ongoing investigations or the identification of additional information in the future could have a material impact on the Group’s financial position, results of operations, or cash flows.

( Amounts in the tables are expressed in billions of Rupiah, unless otherwise stated)

37. FINANCIAL INSTRUMENTS (continued)

a. Financial assets and financial liabilities (continued)

iii. Fair value measurement

Fair value is the amount for which an asset could be exchanged, or a liability settled, between parties in an arm's length transaction.

The fair values of short-term financial assets and financial liabilities with maturities of one year or less (cash and cash equivalents, trade and other receivables, other current financial assets, trade and other payables, accrued expenses, and short-term bank loans) and other non-current assets are considered to approximate their carrying amounts as the impact of discounting is not significant.

The fair values of long-term financial assets (other non-current assets (long-term trade receivables and restricted cash)) approximate their carrying amounts as the impact of discounting is not significant.

The Group determined the fair value measurement for disclosure purposes of each class of financial assets and financial liabilities based on the following methods and assumptions:

(a) Fair value through profit or loss, primarily consists of stocks, mutual funds, corporate and government bonds, and convertible bonds. Stocks and mutual funds actively traded in an established market are stated at fair value using quoted market price or, if unquoted, determined using a valuation technique. The fair value of convertible bonds and subsidiaries investments (non-listed equity investments) are determined using valuation technique. Corporate and government bonds are stated at fair value by reference to prices of similar securities at the reporting date.
(b) The fair values of long-term financial liabilities are estimated by discounting the future contractual cash flows of each liability at rates offered to the Group for similar liabilities of comparable maturities by the bankers of the Group, except for bonds which are based on market price.
--- ---

The fair value estimates are inherently judgemental and involve various limitations, including:

(a) Fair values presented do not take into consideration the effect of future currency fluctuations.
(b) Estimated fair values are not necessarily indicative of the amounts that the Group would record upon disposal/termination of the financial assets and liabilities.
--- ---

b. Financial risk management objectives and policies

The Group’s activities expose it to a variety of financial risks such as market risks (including foreign exchange risk, market price risk, and interest rate risk), credit risk, and liquidity risk. Overall, the Group’s financial risk management program is intended to minimize losses on the financial assets and financial liabilities arising from fluctuation of foreign currency exchange rates and the fluctuation of interest rates. Management has a written policy on foreign currency risk management mainly on time deposit placements and hedging to cover foreign currency risk exposures for periods ranging from 3 up to 12 months.

Financial risk management is carried out by the Group Financial Accounting and Treasury Unit under policies approved by the Directors. The Group Financial Accounting and Treasury Unit identifies, evaluates and hedges financial risks.

37. FINANCIAL INSTRUMENTS (continued)

b. Financial risk management objectives and policies (continued)

i. Foreign exchange risk

The Group is exposed to foreign exchange risk on sales, purchases and borrowings that are denominated in foreign currencies. The foreign currency denominated transactions are primarily in U.S. Dollar. The Group’s exposures to other foreign exchange rates are not material.

Increasing risks of foreign currency exchange rates on the obligations of the Group are expected to be partly offset by the effects of the exchange rates on time deposits and receivables in foreign currencies that are equal to at least 25% of the outstanding current foreign currency liabilities.

The following table presents the Group’s financial assets and financial liabilities exposure to foreign currency risk:

2025 2024
U.S. Dollar U.S. Dollar
(in billions) (in billions)
Financial assets 1.03 1.02
Financial liabilities (0.23) (0.17)
Net exposure 0.80 0.85

Sensitivity analysis

A strengthening of the U.S. Dollar as indicated below, against the Rupiah at  December 31, 2025 would have decreased equity and profit or loss by the amounts shown below. This analysis is based on foreign currency exchange rate variances that the Group considered to be reasonably possible at the reporting date. The analysis assumes that all other variables, in particular interest rates, remain constant.

Equity/profit (loss)
December 31, 2025
U.S. Dollar (1% strengthening) 135

A weakening of the U.S. Dollar against the Rupiah at December 31, 2025, would have had an equal but opposite effect on the above currencies to the amounts shown above, on the basis that all other variables remain constant.

ii. Market price risk

The Group is exposed to changes in debt and equity market prices related to financial assets measured at FVTPL carried at fair value. Gains and losses arising from changes in the fair value of financial assets measured at FVTPL are recognized in the consolidated statements of profit or loss and other comprehensive income.

The performance of the Group’s financial assets measured at FVTPL is monitored periodically, together with a regular assessment of their relevance to the Group’s long-term strategic plans.

As of December 31, 2025, management considered the price risk for the Group’s financial assets measured at FVTPL to be immaterial in terms of the possible impact on profit or loss and total equity from a reasonably possible change in fair value.

37. FINANCIAL INSTRUMENTS (continued)

b. Financial risk management objectives and policies (continued)

iii. Interest rate risk

Interest rate fluctuation is monitored to minimize any negative impact to financial performance. Borrowings at variable interest rates expose the Group to interest rate risk (Notes 18 and 19). To measure market risk pertaining to fluctuations in interest rates, the Group primarily uses interest margin and maturity profile of the financial assets and liabilities based on changing schedule of the interest rate.

At reporting date, the interest rate profile of the Group’s interest-bearing borrowings was as follows:

2025 2024
Fixed rate borrowings 37,407 48,097
Variable rate borrowings 37,504 28,771

Sensitivity analysis for variable rate borrowings

As of December 31, 2025, a decrease (increase) by 25 basis points in interest rates of variable rate borrowings would have increased (decreased) equity and profit or loss by Rp94 billion, respectively. The analysis assumes that all other variables, in particular foreign currency rates, remain constant.

iv. Credit risk

The following table presents the maximum exposure to credit risk of the Group’s financial assets:

2025 2024
Cash and cash equivalents 34,228 33,905
Other current financial assets 1,420 1,285
Trade receivables 11,223 12,193
Other receivables 172 621
Other non-current assets 208 165
Total 47,251 48,169

The Group is exposed to credit risk primarily from cash and cash equivalents, trade receivables and other receivables. The credit risk is controlled by continuous monitoring of outstanding balance and collection. Credit risk from balances with banks and financial institutions is managed by the Group Financial Accounting and Treasury Unit in accordance with the Group’s written policy.

The Group placed the majority of its cash and cash equivalents in state-owned banks because they have the most extensive branch networks in Indonesia and are considered to be financially sound banks, as they are owned by the State. Therefore, it is intended to minimize financial loss through banks and financial institutions’ potential failure to make payments.

The customer credit risk is managed by continuous monitoring of outstanding balances and collection. Trade and other receivables do not have any major concentration of risk whereas no customer receivable balance exceeds 7.95% of trade receivables as of  December 31, 2025 (2024: 5.76%).

Management is confident in its ability to continue to control and sustain minimal exposure to the customer credit risk given that the Group has recognized sufficient provision for impairment of receivables to cover incurred loss arising from uncollectible receivables based on existing historical data on credit losses.

v. Liquidity risk

Liquidity risk arises in situations where the Group has difficulties in fulfilling financial liabilities when they become due.

Prudent liquidity risk management implies maintaining sufficient cash in order to meet the Group’s financial obligations. The Group continuously performs an analysis to monitor financial position ratios, such as liquidity ratios and debt-to-equity ratios, against debt covenant requirements. The Group has a net current liabilities position as of December 31, 2025, and is expected to meet its current obligations by having access to sufficient undrawn bank facilities amounted to Rp42,109 billion and US$67 million (Note 19b).

The following is the maturity profile of the Group’s financial liabilities based on contractual undiscounted payments:

38. CAPITAL MANAGEMENT

The capital structure of the Group is as follows:

2025 2024 (as restated, Note 2z)
Amount Portion Amount Portion
Short-term debts 6,929 3.37% 11,525 5.47%
Long-term debts 67,982 33.07% 65,343 31.02%

Total 205,596 100.00% 210,676 100.00%

The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order to provide returns for stockholders and benefits to other stakeholders and to maintain an optimum capital structure to minimize the cost of capital.

Periodically, the Group conducts debt valuation to assess possibilities of refinancing existing debts  with new ones with have more efficient cost that will lead to more optimized cost-of-debt. In case of idle cash with limited investment opportunities, the Group will consider buying back its shares of stock or paying dividend to its stockholders.

In addition to complying with loan covenants, the Group also maintains its capital structure at the level it believes will not risk its credit rating and which is comparable with its competitors.

Debt-to-equity ratio (comparing net interest-bearing debt to total equity) is a ratio which is monitored  by management to evaluate the Group’s capital structure and review the effectiveness of the Group’s debts. The Group monitors its debt levels to ensure the debt-to-equity ratio complies with or is below the ratio set out in its contractual borrowings arrangements and that such ratio is comparable or better than that of regional area entities in the telecommunications industry.

The Group’s debt-to-equity ratio as of December 31, 2025 and 2024, respectively, were as follows:
