What Triggered the Latest Fall in Adani Group Stocks

Adani Group stocks came under heavy selling pressure after the US Securities and Exchange Commission sought court approval to serve summons directly via email to Gautam Adani and Sagar Adani.

This move followed two failed attempts to route summons through Indian authorities, raising concerns about the seriousness and persistence of the US civil probe. The renewed uncertainty acted as the immediate trigger for the Adani stock crash, with investors aggressively cutting exposure as Adani shares fell across the board.

As a result, over ₹1.4 lakh crore in market capitalisation was wiped out across Adani Group companies within a single trading session, reinforcing fears of prolonged volatility.

Why the US SEC Is Seeking to Email Summons

On 21 January 2026, the SEC approached a Brooklyn federal court requesting permission to bypass traditional diplomatic channels under the Hague Convention and serve summons electronically.

Key reasons cited by the SEC

• Indian authorities rejected earlier requests on procedural grounds, including signature requirements

• Prolonged delays in the cross-border service of legal documents

• The need to move forward with an ongoing US civil securities case

For investors, this signals that the case is not dormant and that US regulators remain actively engaged.

Allegations Against Gautam Adani and Sagar Adani

The SEC’s November 2024 civil complaint alleges:

• Payment of $265 million in bribes to Indian officials

• Bribes allegedly linked to securing solar power contracts

• Involvement of Adani Green Energy in the transaction flow

• Misleading disclosures to US bond investors during a $150–175 million bond issue in September 2021

Important legal clarifications

• The case is civil, not criminal

• No bribery charges have been filed under the US Foreign Corrupt Practices Act against the individuals

• A parallel US criminal investigation is examining securities fraud and wire fraud, but remains unresolved

Despite these clarifications, the allegations contributed materially to the Adani stock crash as investors priced in worst-case regulatory scenarios.

How the US SEC Case Impacted Adani Group Share Prices and Market Value

The renewed regulatory overhang triggered aggressive selling across Adani stocks on 23 January 2026, compounded by weak quarterly earnings at Adani Green Energy. As Adani shares fell, the sell-off extended beyond the directly named entities.

• Combined market value erosion estimated at $12.5 to $17 billion

• Broader market sentiment also weakened, with the Nifty declining nearly %

• Adani Group stocks underperformed the benchmark significantly

As of 24 January 2026, there was no meaningful recovery, reflecting fragile investor confidence.

Stock-wise Performance Snapshot

Percentage declines ranged from 5% to over 15%, with Adani Enterprises emerging as the top Nifty 50 loser. The data highlights how broadly the Adani stock crash impacted group companies.

Adani Group’s Official Response

Adani Group companies issued stock exchange disclosures denying the allegations.

Key statements

• The allegations were termed baseless

• The group stated it would pursue all legal remedies

• Adani Green clarified it is not a party to the proceedings

• Adani Ports stated it has no direct involvement

No separate response was issued immediately on the SEC’s 21 January filing.

Key Risks for Adani Group Investors After the SEC Case

For investors analysing Adani Group stocks, the risks now extend beyond quarterly earnings.

1. Regulatory and litigation overhang

• Court approval timelines remain uncertain

• Analysts expect at least two weeks of heightened volatility

2. Balance sheet sensitivity

• High consolidated debt

• Low interest coverage in certain subsidiaries

• Dependence on continuous refinancing

3. Global funding and reputation risk

• US dollar bond exposure increases litigation sensitivity

• Potential impact on overseas funding costs

• Delays or scrutiny on international projects

4. Market sentiment fragility

• Past events have amplified investor reaction to regulatory news

• Any adverse court development could trigger further de-rating

These factors explain why Adani shares fell sharply despite broader markets remaining relatively stable.

How This Compares With the 2023 Hindenburg Episode

Unlike in earlier phases, investors' assumptions about regulatory resolution are now being tested again.

What Investors Should Monitor Next

• US court rulings on the SEC’s summons request

• Any formal response from Gautam Adani or Sagar Adani

• Quarterly earnings and cash flow trends
