Mahanagar Telephone Nigam Ltd Forensic Report - SOIC x StockScans Report

as of Sep 2026

Mahanagar Telephone Nigam Ltd's FY2025-26 audit is a clean break from its prior record: after seven consecutive years of qualified opinions, the auditors escalated to an adverse opinion, stating the financial statements do not give a true and fair view. The company's bank debt sits in default and NPA across seven lenders, while the Government of India services its sovereign-guaranteed bond stack through interest-free loans. Related-party balances with BSNL and DoT remain large and unreconciled, and a multi-thousand-crore stack of disputed demands and awards hangs over the balance sheet.

Key findings

  1. Bank debt is in default and NPA across seven lenders, with the sovereign servicing bond payments Critical - All loan accounts were declared Non-Performing Assets by lender banks as of 31 March 2026, and current accounts were frozen. Total default to seven banks rose from Rs. 8,584.93 crore as of 15/07/2025 to Rs. 9,574.61 crore as of 07/08/2026. The Government of India provided an interest-free loan of Rs. 2,980.92 crore during FY2025-26 for interest on Sovereign Guarantee Bonds, with no interest stipulated or provided.
  2. Related-party balances with BSNL and DoT are large, unreconciled, and repeatedly flagged Major - Net amount recoverable from BSNL was Rs. 4,101.34 crore as at 31 March 2026, subject to reconciliation and confirmation, with recoverability not ascertainable per the auditor. Net amount payable to DoT was Rs. 429.60 crore, also subject to reconciliation, with no interest agreement on the current account. The Board's Report states no material related party transactions under Section 188 occurred and Form AOC-2 is not applicable.
  3. A multi-thousand-crore stack of disputed DoT demands and adverse awards sits unprovided Major - DoT's provisional assessment for license fee and spectrum usage charges shows a demand of Rs. 5,370.09 crore, up from Rs. 5,132.24 crore in FY2024-25, all shown as contingent liability. An arbitrator's award of Rs. 160 crore with interest in the Canara Bank matter has grown to a contingent liability of Rs. 472.60 crore. Auditors state Penal Guarantee Fees of Rs. 352.30 crore were classified as contingent liability instead of provision, overstating profit by that amount.
  4. Revenue recognition has been repeatedly challenged, with revenue booked on BSNL's collections Major - For FY2025-26, MTNL recognised revenue share of Rs. 156.51 crore against migrated customers computed on BSNL's collections, which auditors state is not proper implementation of the revenue-sharing arrangement and not independently verifiable. Auditors state revenue ought to be recognised on an accrual basis per Ind AS. Dues from operators on revenue-sharing agreements are not treated as debtors and are excluded from doubtful-debt provisioning, a practice repeated from FY2021-22 through FY2025-26.
  5. Board has been structurally non-compliant on independent-director composition for six years Major - As on 31.03.2026, MTNL required six Independent Directors but had only two, and the Secretarial Audit qualified that one half of the Board was not comprised of Independent Directors. The promoter (President of India) held 56.25% of MTNL, and no director held any equity shares as on 31.03.2025. All director appointments were made by the Department of Telecommunications, and at the 39th AGM all five director resolutions passed with over 99.95% votes in favour.
  6. Auditors have qualified every annual report from FY2020 through FY2026 on impairment Major - The statutory auditors issued a qualified opinion on impairment in each of the seven annual reports from FY2019-20 through FY2025-26, unable to ascertain the impairment provision required for cash-generating units. MTNL stated in each annual report that there was no indication of impairment on the basis of the company as a whole as a single cash-generating unit.

What to watch

Bottom line: This is a record of escalating audit severity, unresolved defaults, and a sovereign guarantor absorbing the company's bond obligations through interest-free loans. The risk is not a single event but the compounding of an adverse opinion, unreconciled related-party balances, and a disputed-demand stack that keeps growing. Watch the escrow extension, the arbitration hearing, and the DoT assessment revision for the next turn.
