Morgan Stanley Banker Accidentally Sends 'Internal Deal List' — Exposes About 60 Asian IPOs, M&A, Block Trades

Six知情人士透露，摩根士丹利( MS-US ) 一名負責亞洲金融投資人業務的資深銀行家，近日在寄送給客戶的每週更新電子郵件中，意外附上內部交易清單，導致好幾筆亞洲潛在交易資訊曝光。

According to Reuters, sources said the banker had intended to send a regular weekly update to clients but mistakenly attached the internal deal list used by the financial sponsor team.

Morgan Stanley's spokesperson replied via email on Thursday (24th): "Morgan Stanley takes client confidentiality extremely seriously. We have taken swift measures to address this unintentional information sharing incident and continue to communicate with relevant parties."

According to a screenshot of the email seen by Reuters, the banker later recalled the message, apologized for the oversight, and urged recipients to delete copies of the attachment and refrain from forwarding the document.

The list, dated September 21, outlined approximately 60 ongoing initial public offerings (IPOs), mergers and acquisitions (M&A), and block trades across Greater China, South Korea, Southeast Asia, India, and Europe, the Middle East, and Africa (EMEA).

The list also included over 50 transactions categorized as "proposal stage" and nearly 30 marked as "on hold," all involving companies based in Asia.

The vast majority of companies listed were portfolio firms of global and Asian private equity and venture capital firms.

According to Bloomberg, as the document circulated among competitors, some industry players seized the opportunity to gain a competitive edge.

Several bankers at rival banks said they would use the list to identify deals and pursue potential clients. Others said most transactions were already known, so they were not surprised.

Traders and investors are also closely watching the potential block trades mentioned in the list.

This incident is an embarrassing lapse for Morgan Stanley, which has long been one of the leading underwriters for Hong Kong stock issuances and Asian M&A deals.

While such errors are uncommon, the event highlights the sensitivity of information handled by investment banking teams, where detailed information about potential client transactions is typically strictly confidential.

Reports indicate that premature leaks of upcoming stock placements could complicate matters for clients conducting block trades, especially if details become public before the transaction officially launches.

Such disclosures could lead investors to anticipate increased stock supply in the market, putting downward pressure on share prices, potentially reducing proceeds for sellers and increasing the difficulty for banks executing the deals.

After news of the leak emerged, Morgan Stanley informed employees via an internal memo that all interactions with clients and media must be reported to senior management.

According to one source, employees were also required to undergo a compliance training session, including how to respond to the aftermath of misdirected emails, though it remains unclear whether this training was a direct response to this specific incident.

Sources said no clients have ceased working with Morgan Stanley due to this leak as of now.
