NEW YORK, April 27, 2012 – Lazard Ltd (NYSE: LAZ) today reported operating revenue¹ of $499 million for the quarter ended March 31, 2012. Net income, as adjusted¹, was $45 million, or $0.33 per share (diluted). These results exclude the pre-tax charge of $25 million related to previously disclosed staff reductions.

Net income on a U.S. GAAP basis, which includes the costs related to staff reductions, was $26 million, or $0.20 per share (diluted), for the quarter ended March 31, 2012. A reconciliation of our U.S. GAAP results to the adjusted results is presented on page 14 of this press release.

“Our first quarter revenues show the breadth and strength of Lazard’s model,” said Kenneth M. Jacobs, Chairman and Chief Executive of Lazard. “Our balanced mix of businesses continues to provide multiple sources of income contributing to our growth.”

“The macroeconomic environment has improved since last summer but remains uncertain. If this improvement continues, strategic advisory activity will likely increase,” said Mr. Jacobs. “Asset Management continued its strong pattern of growth in the first quarter, with assets under management rising above the full-year average for 2011. Our investment platforms continue to produce strong relative performance. Lazard and our shareholders are in excellent position to benefit from these positive trends in both our businesses.”

“Our revenues were strong in the first quarter, but, as previously reported, earnings are being impacted by the high level of amortization expense from previous years’ deferred compensation, primarily related to the 2008 grant,” said Matthieu Bucaille, Chief Financial Officer of Lazard. “However, consistent with our objectives, and our view regarding current market conditions, our compensation and benefits expense for the first quarter assumes an awarded compensation ratio of approximately 60%, a decrease from the full-year 2011 ratio of 62%.”

We encourage you to visit our Lazard.com investor relations website to read our shareholder letter, answers to our shareholders’ frequently asked questions, and supporting documents, which provide a comprehensive discussion regarding our strategy, financial targets and business model.

OPERATING REVENUE

Financial Advisory

In the text portion of this press release, we present our Financial Advisory results as Strategic Advisory and Restructuring. Strategic Advisory includes M&A, Sovereign and Government Advisory, Capital Markets, Lazard Middle Market, Private Funds and Other Advisory businesses.

Financial Advisory operating revenue was a first-quarter record of $277 million, 21% higher than the first quarter of 2011, and the fourth quarter of consecutive quarterly growth.

2

Strategic Advisory operating revenue was $207 million in the first quarter of 2012, 7% higher than the first quarter of 2011. This was driven by M&A, which increased 18% compared to the first quarter of 2011, due in part to the strong performance of Lazard Middle Market, as well as Sovereign and Government Advisory.

Restructuring operating revenue of $70 million was 97% higher than the first quarter of 2011, reflecting the closing of several large assignments during the quarter. The increase in restructuring revenue for the 2012 first quarter does not represent an expectation of restructuring revenue in future periods.

During the quarter, we remained engaged in highly visible, complex M&A transactions and other advisory assignments, including cross-border transactions, spin-offs, distressed asset sales, and government advisory in the Americas, Europe and Asia.

Among the major M&A transactions or assignments that were completed during the first quarter of 2012 were the following (clients are in italics): Skandia Liv’s SEK 22.5 billion acquisition of Skandia AB from Old Mutual; European Goldfields’ C$2.5 billion sale to Eldorado Gold; Simon Property’s $2 billion acquisition of a 28.7% stake in Klépierre; and, the Special Committee of the Board of Directors of 99 Cents Only Stores in the $1.6 billion sale to Ares Management, Canada Pension Plan Investment Board and Gold/Schiffer Family.

Lazard is advising on three of the ten largest M&A transactions announced in the first quarter of 2012, including: GDF Suez/Electrabel in the $12.6 billion acquisition of the 30% stake it did not already own in International Power; Tyco’s combination of its Flow Control business with Pentair in a $10 billion all-stock merger; and, the Supervisory Board of TNT Express in the €5.2 billion sale to United Parcel Service.

Our Sovereign and Government Advisory business was active with assignments that included advising the government of Greece on the completion of its successful bond exchange, the largest in history. We also advised the Commonwealth of Australia on the $11 billion definitive agreement between National Broadband Network and Telstra, which came into force in the first quarter of 2012.

We have been involved in many of the most notable recent restructurings, such as A&P, Eastman Kodak, Lehman Brothers and Spanish Broadcasting Systems.

Please see a more complete list of Strategic Advisory transactions that were completed in the first quarter of 2012, as well as Restructuring assignments, on pages 7 - 9 of this release.

Asset Management

Assets under management (AUM) were $157 billion as of March 31, 2012, an 11% increase compared to $141 billion as of December 31, 2011, and 3% above the full-year 2011 average AUM of $152 billion. Asset Management experienced net outflows of $0.2 billion in the first quarter of 2012.

Asset Management operating revenue was $210 million in the first quarter of 2012, 6% lower than the first quarter of 2011, and 3% higher than the fourth quarter of 2011.

Management fees were $200 million in the first quarter of 2012, 3% lower than the first quarter of 2011, 5% higher than the fourth quarter of 2011 and directionally consistent with the change in the quarterly average AUM. Average AUM for the quarter was $150 billion, 5% lower than the first quarter of 2011 and 7% higher than the fourth quarter of 2011. Incentive fees were $2.6 million in the first quarter of 2012, 50% lower than the first quarter of 2011, primarily due to a change in one mandate from a quarterly to an annual performance fee basis.

Our client mix remained broadly diversified by investment strategy and geography. We continued to win new mandates and to provide superior investment solutions to our clients around the world.

OPERATING EXPENSES

Compensation and Benefits

In managing compensation and benefits expense, we focus on annual awarded compensation (cash compensation and benefits plus deferred incentive compensation with respect to the applicable year, net of estimated future forfeitures). We believe annual awarded compensation reflects the actual annual compensation cost more accurately than the GAAP measure of compensation cost, which measures applicable-year cash compensation and the amortization of deferred incentive compensation principally attributable to previous years’ deferrals. We believe that by managing our business using awarded compensation with a consistent deferral policy, we can better manage our compensation costs, increase our flexibility in the future and build shareholder value over time.

Adjusted compensation and benefits expense¹, including related accruals, was $313 million for the first quarter of 2012, when excluding the effects of the previously disclosed 2012 expense relating to staff reductions. The corresponding adjusted GAAP compensation ratio was 62.7%, compared to 58.9% for the same period in 2011, but lower than the full-year 2011 ratio of 62%, which reflected the actual operating revenue and the adjusted GAAP compensation expense for the year.

4

The first-quarter 2012 adjusted GAAP compensation ratio includes, among other items, amortization expense related to the 2008 deferred compensation. Our amortization expense is higher in 2012, compared to 2011, primarily because of the overlapping vesting periods. For the full year of 2012, we estimate, as of today, amortization expense of approximately $341 million vs. $289 million in 2011.

The first-quarter 2012 adjusted GAAP compensation ratio assumes, based on current market conditions, an awarded compensation ratio of approximately 60%, compared to approximately 62% awarded for the full year of 2011.

Our goal remains to grow annual awarded compensation expense at a slower rate than revenue growth, and to achieve a compensation-to-revenue ratio over the cycle in the mid- to high-50s percentage range on both an awarded and adjusted GAAP basis¹ with discipline on deferrals.

Non-Compensation Expense

Non-compensation expense, on an adjusted basis¹, of $105 million represented 21.1% of operating revenue compared to 20.3% in the first quarter of 2011 and 21.2% for the full year 2011. Non-compensation expense in the 2012 first quarter was negatively impacted by a high level of deal-related third party fees, and increases in occupancy costs and business activity levels. This excluded non-compensation costs related to staff reductions in 2012.

TAXES

The provision for taxes, on an adjusted basis¹, was $15 million for the first quarter of 2012, compared to $14 million for the first quarter of 2011. The effective tax rate on the same basis for the first quarter of 2012 was 25.7%, compared to the relatively low level of 18.9% for the first quarter of 2011.

CAPITAL MANAGEMENT AND BALANCE SHEET

Our primary capital management goals include reducing excess cash, managing debt, and increasing returns to shareholders through dividends and share repurchases.

On April 24, 2012, our Board of Directors voted to increase the quarterly dividend on Lazard’s outstanding Class A common stock by 25%, to $0.20 per share. This planned dividend increase was previously announced in Lazard’s fourth-quarter 2011 earnings release. Since the fourth quarter of 2010, the dividend has increased by 60%.

5

During the 2012 first quarter, we continued our share repurchase program with the goal of, at minimum, offsetting potential dilution from equity-based awards granted at year end. We bought back approximately 2.4 million shares of our Class A common stock and exchangeable interests, for approximately $71 million during the quarter. As of March 31, 2012, our remaining share repurchase authorization was $142 million. On April 24, 2012, the Lazard Board of Directors authorized additional share repurchases of up to $125 million, which expires on December 31, 2013.

Lazard’s financial position remains strong and low risk with approximately $766 million in cash and cash equivalents at March 31, 2012, the majority of which is invested in U.S. Government and agency money market funds. Total stockholders’ equity related to Lazard’s interests is $738 million.

(See Reconciliation of U.S. GAAP to Adjusted Statement of Operations.)
