Legal Titans Trilegal, SAM, CAM Steer PhonePe’s $1.5B IPO Filing

India’s top-tier law firms are marshalling their multi-disciplinary expertise as fintech giant PhonePe, backed by Walmart, officially commences its journey to the public markets with a proposed $1.5 billion Initial Public Offering (IPO). In a move signaling one of the most anticipated market debuts in the Indian technology sector, PhonePe has utilized the confidential filing route with the Securities and Exchange Board of India (SEBI) for its Draft Red Herring Prospectus (DRHP).

The transaction has brought together a formidable trio of legal advisors, with Trilegal taking the helm as counsel to the company, Shardul Amarchand Mangaldas & Co (SAM) advising the promoters, and Cyril Amarchand Mangaldas (CAM) representing the book running lead managers. This congregation of legal heavyweights underscores the complexity and high stakes of preparing a regulated digital payments leader for public scrutiny and investment.

Transaction Structure and Shareholder Dynamics

The proposed IPO is reportedly structured as a pure Offer-for-Sale (OFS), a mechanism that allows existing shareholders to divest their holdings without raising new capital for the company. This structure points to a strategic move by PhonePe’s major investors—including parent company Walmart , alongside prominent backers like Tiger Global and Microsoft —to monetize their investment and unlock value.

According to reports, these shareholders are planning to collectively dilute approximately 10 percent of their combined stake. For the legal teams involved, particularly SAM advising the promoters and selling shareholders, this necessitates meticulous drafting of the offer documents to ensure precise disclosures regarding share ownership, lock-in periods, and the terms of the sale, all while navigating the intricate web of SEBI’s Issue of Capital and Disclosure Requirements (ICDR) Regulations.

The decision to use SEBI's confidential filing route, a relatively new mechanism, allows the company and its bankers to receive feedback from the regulator on the DRHP without making the sensitive business and financial details public immediately. This pre-filing confidentiality provides strategic flexibility, enabling the company to assess market conditions and refine its offering before a full-scale public launch.

"Leading law firm Trilegal is advising Walmart-backed PhonePe while Shardul Amarchand Mangaldas & Co is acting for its promoters on the Indian fintech giant’s proposed $1.5 billion initial public offering (IPO) of equity shares, for which the company has filed its draft red herring prospectus through SEBI’s confidential filing route."

The Multi-Disciplinary Legal Gauntlet

The sheer scale of the legal teams deployed by Trilegal and CAM reveals the comprehensive due diligence required for a fintech IPO of this magnitude. Beyond the core capital markets work, the mandate spans a wide spectrum of specialized legal practices, each critical to ensuring a successful and compliant listing.

Trilegal’s Extensive Advisory to PhonePe:

Trilegal’s role as company counsel involves a deep and wide-ranging legal audit of PhonePe’s entire business. The firm has deployed at least six distinct practice groups to manage the complexities of the filing:

• Capital Markets: Led by partners Vijay Parthasarathi and Vinay Sirohia , this team is at the forefront, responsible for drafting the DRHP, liaising with SEBI, and ensuring all disclosures meet regulatory standards.
• Corporate: Partners Vishruta Kaul, Wiseroy Damodaran, and Amit Khansaheb are handling the intricate corporate structuring, shareholder agreements, and corporate governance aspects precedent to the IPO.
• Financial Regulatory: Given PhonePe's core business, the financial regulatory team, led by partners Shruti Rajan and Anubhav Ghosh , plays a pivotal role. Their work is central to validating the company’s compliance with directives from the Reserve Bank of India (RBI), particularly concerning its newly secured payment aggregator license, which is a cornerstone of its merchant services expansion.
• Governance & Compliance: Partner Sampath Kumar Rajagopalan is leading the efforts to align PhonePe’s internal policies and board structures with the stringent governance norms required for a publicly listed entity.
• Labour & Employment and Dispute Resolution: Partners Apeksha Mattoo and Shalaka Patil , respectively, are overseeing due diligence on employment-related matters and outstanding litigation, both of which are critical areas for risk disclosure in the DRHP.

CAM’s Counsel to the Underwriters:

On the other side of the table, Cyril Amarchand Mangaldas, advising the book running lead managers, is conducting its own rigorous due diligence to protect the interests of the investment banks underwriting the issue. The CAM team, led by capital markets head Manan Lahoty and partner Vishal Yaduvanshi , is supported by specialists in employment law ( Bharath Reddy ), financial services regulatory practice ( Pallavi Singh Rao ), and insurance ( Indranath Bishnu ). This parallel diligence process is essential for verifying the accuracy of the company’s disclosures and mitigating potential liabilities for the underwriters.

SAM’s Strategic Role for Promoters:

Shardul Amarchand Mangaldas, led by corporate partner Raghubir Menon and capital markets heads Prashant Gupta and Abhiroop Datta , holds the crucial responsibility of advising the promoters and selling shareholders. Their mandate involves aligning the interests of various stakeholders, structuring the OFS, and navigating the legal framework governing promoter share sales in an IPO context.

Implications for the Fintech and Legal Sectors

The PhonePe IPO is a bellwether event for India’s fintech industry. A successful listing would not only set a new valuation benchmark but also pave the way for other mature fintech startups to tap the public markets. For the legal community, it reinforces the trend of large, complex transactions requiring deep, multi-specialist teams.

The extensive involvement of financial regulatory lawyers highlights the increasing convergence of technology and finance, making regulatory expertise a non-negotiable component of any major fintech transaction. The recent grant of a payment aggregator license by the RBI to PhonePe is a significant value driver mentioned in the deal narrative, enhancing its digital payments ecosystem and demonstrating regulatory buy-in. The legal diligence surrounding this license and its implications for future business growth would have been a critical focus area for all firms involved.

As PhonePe moves closer to its market debut, the meticulous legal groundwork laid by Trilegal, SAM, and CAM will be fundamental to its success. This transaction serves as a powerful case study in the collaborative and highly specialized nature of modern corporate law, where capital markets acumen must be seamlessly integrated with deep domain knowledge in regulation, technology, and corporate governance to navigate the path to a public listing.
