Jan 15 (Reuters) - Morgan Stanley's ( MS ) profit rose as its investment bankers reaped a windfall from deals in the fourth quarter, sending its shares 1.6% higher in premarket trading.

A flurry of large transactions pushed global mergers and acquisitions past $5.1 trillion last year as exuberance over AI and ‌rate cuts by the Federal Reserve encouraged CEOs to pursue buyouts.

Morgan Stanley's ( MS ) investment banking revenue rose to $2.41 billion ​in the quarter, compared with $1.64 billion a year earlier.

Equity markets surged to record highs ‍late last year despite volatility in the first half ⁠from U.S. President Donald ⁠Trump's tariff policies.

The earnings mirror those of Wall Street rivals including Citigroup, which benefited from a surge ‌in M&As and initial public offerings (IPOs).

Morgan Stanley ( MS ) posted ​a profit of $4.40 billion, or $2.68 per share, for the three months ended December 31, it said on Thursday. That compares with $3.71 billion, ⁠or $2.22 per share, a year earlier.

Advisory ‍revenue surged 45% ​to $1.13 billion in the quarter.

Morgan Stanley ( MS ) CEO Ted Pick said in a statement that "investment banking activity accelerated and global markets remained strong."

ADVISOR TO BIG ‍IPOS

Despite a bumper IPO market being disrupted by the longest-ever U.S. government shutdown late last year, soaring valuations and falling interest rates emboldened companies to pursue follow-on equity offerings and convertible bond deals.

Morgan Stanley's ( MS ) debt underwriting revenue surged nearly 93% to $785 million, driven by higher issuance volumes. Its equity underwriting revenue jumped 8.6%, ​after more ‍than doubling in the year-ago quarter.

The bank was among the joint book-running managers on big initial public offerings late in the quarter, including electric ​aircraft maker BETA Technologies, tax advisory firm Andersen Group, and medical supply giant Medline, the biggest IPO of 2025.

The bank also served as the exclusive advisor to Meta on the tech giant's joint venture with Blue Owl Capital to develop the Hyperion data center campus in Louisiana.

Equities trading remained a bright spot as clients rebalanced their portfolios amid volatile markets ​whipsawed by shifting monetary policy expectations and concerns about an AI bubble.

Morgan Stanley ( MS ) landed key roles in marquee deals during the quarter, including advising data infrastructure company Confluent on its $11 billion deal to be bought ‍by IBM.
