•Annualized return on adjusted tangible equity of 7.2%1

•Total net revenues of $1.44 billion

Ø Investment Banking net revenues of $568 million

•Our Board of Directors has increased our share buyback authorization back to a total of $250 million

•On November 1, 2022, we completed our merger with Jefferies Group LLC. This merger eliminated Jefferies Group LLC’s requirement to file Form 10-Qs, Form 10-Ks, and other duplicative processes, and resulted in us assuming Jefferies Group's debt obligations. In connection with the merger we have transferred our legacy merchant banking investments to our Investment Banking and Capital Markets or Asset Management segment and have reorganized the presentation of our segments and Net revenues to align with the way we are now managing our business. Additionally, corporate activities are now fully allocated to these segments. Prior year amounts have been revised to conform to this current presentation. Refer to Note 18 for further information.

"Monetizing our legacy merchant banking portfolio and returning capital to shareholders remains one of our overriding priorities, and we made continued progress in 2022. We expect to take a further important step later this week with our spin-off to shareholders of Vitesse Energy ("Vitesse"). In 2022, we returned an aggregate of $1.14 billion to shareholders in the form of $280.1 million in dividends and the repurchase of 25.6 million shares for a total of $859.6 million, or $33.58 per share. Over the last five years, we have now returned $5.0 billion in total capital to shareholders, representing two-thirds of total tangible book value3 at January 1, 2018 and including 152.8 million shares repurchased at an average of $23.57 per share. Further, our Vitesse spin-off delivers to our shareholders an additional estimated more than $500 million of our shareholders' equity. Pro forma for the Vitesse spin-off, we will have returned over $5.5 billion in total capital to shareholders over the last five years, representing over 72% of tangible book value3 at January 1, 2018.

"In sum, we achieved a respectable return on adjusted tangible equity of 10.3%1 in a very difficult environment, enhanced our market position in our core businesses and simplified our corporate structure. As we move forward in 2023, we have never been more optimistic about our human capital, product capabilities, industry expertise and geographic breadth, which we intend to continue to aggressively deliver to our clients going forward. Our goal is to continue to gain market share, further strengthening our 'never better' competitive position, and continue our quest to be the best full service global investment banking firm."

Components of Denominator for Earnings Per Share

The denominators used to calculate basic and diluted earnings per share are as follows (in thousands):

1.Annualized return on adjusted tangible equity (a non-GAAP financial measure) is defined as annualized adjusted net earnings (a non-GAAP financial measure) divided by our beginning of period adjusted tangible shareholders' equity (a non-GAAP financial measure). Refer to schedule on page 10 for reconciliation to U.S. GAAP amounts.

2.Allocated net interest represents an allocation to Asset Management of certain of our long-term debt interest expense, net of interest income on our Cash and cash equivalents and other sources of liquidity. Allocated net interest has been disaggregated to increase transparency and to present direct Asset Management revenues. We believe that aggregating Allocated net interest would obscure the revenue results by including an amount that is unique to our credit spreads, debt maturity profile, capital structure, liquidity risks and allocation methods. Refer to Selected Financial Information on pages 5 to 6.

3.Tangible book value (a non-GAAP financial measure) is defined as shareholders' equity less intangible assets, net and goodwill. Refer to schedule on page 11 for reconciliation to U.S. GAAP amounts.

4.Adjusted annualized return on adjusted tangible equity (a non-GAAP financial measure) is defined as Jefferies' annualized adjusted net earnings excluding the net earnings impact of the $80 million of expense ($80 million, net of tax) related to a regulatory settlement during the current year (a non-GAAP financial measure) divided by our beginning of period adjusted tangible shareholders' equity (a non-GAAP financial measure). Refer to schedule on page 10 for reconciliation to U.S. GAAP amounts.

5.Shares outstanding on a fully diluted basis (a non-GAAP financial measure) is defined as common shares outstanding plus restricted stock units, stock options, conversion of redeemable convertible preferred shares and other shares. Refer to schedule on page 11 for reconciliation to U.S. GAAP amounts.

6.Adjusted tangible book value per fully diluted share (a non-GAAP financial measure) is defined as adjusted tangible book value (a non-GAAP financial measure) divided by shares outstanding on a fully diluted basis (a non-GAAP financial measure). Refer to schedule on page 11 for reconciliation to U.S. GAAP amounts.

7.Tangible shareholders' equity (a non-GAAP financial measure), is defined as shareholders' equity less Intangible assets and goodwill. We believe that tangible equity is meaningful for valuation purposes, as financial companies are often measured as a multiple of tangible equity, making these ratios meaningful for investors.

8.Adjusted net earnings attributable to common shareholders (a non-GAAP financial measure) excludes the $80 million expense ($80 million, net of tax) related to a regulatory settlement in the third quarter. Refer to schedule on page 9 for reconciliation to U.S. GAAP amounts.

9.Allocated net interest is not separately disaggregated for Investment Banking and Capital Markets. This presentation is aligned to our Investment Banking and Capital Markets internal performance measurement.

10.Includes management and performance fees from funds and accounts managed by us as well as our share of fees received by affiliated asset management companies with which we have revenue and profit share arrangements, as well as earnings on our ownership interest in affiliated asset managers.

11.Number of trading loss days is calculated based on trading activities in our Investment Banking and Capital Markets and Asset Management business segments.

12.VaR estimates the potential loss in value of trading positions due to adverse market movements over a one-day time horizon with a 95% confidence level. For a further discussion of the calculation of VaR, see "Value-at-Risk" in Part II, Item 7A "Quantitative and Qualitative Disclosures About Market Risk" in our Annual Report on Form 10-K for the year ended November 30, 2021.

13.Amounts pertaining to November 30, 2022 represent a preliminary estimate as of the date of this earnings release and may be revised in our Annual Report on Form 10-K for the year ended November 30, 2022.

14.Level 3 financial instruments represent those financial instruments classified as such under Accounting Standards Codification 820, accounted for at fair value and included within Financial instruments owned.

15.Leverage ratio equals total assets divided by total equity.

16.Tangible gross leverage ratio (a non-GAAP financial measure) equals total assets less goodwill and identifiable intangible assets divided by tangible equity. The tangible gross leverage ratio is used by rating agencies in assessing our leverage ratio.

17.Adjusted effective tax rate (a non-GAAP financial measure) excludes the $80 million expense related to a regulatory settlement in the current year. Refer to schedule on page 10 for reconciliation to U.S. GAAP amounts.

18.We have reclassified the presentation of certain line items within our Net revenues by sources to streamline our financial statements to better align the presentation of our firm with the strategy of building our investment banking and capital markets and asset management businesses as we continue to reduce our legacy merchant banking portfolio. Historical periods have been recast to conform to these reclassification and presentation changes.

19.We have changed the accounting for our secondary trading activity related to the purchases and sales of corporate loans. Historically, we have accounted for purchases and sales of corporate loans on trade date recognizing the total amount of purchased loans within Financial instruments owned and a corresponding liability within Payables - brokers, dealers and clearing organizations and the total amount of loans sold within Financial instruments sold, not yet purchased and a corresponding asset within Receivables - brokers, dealers and clearing organizations on the Consolidated Statements of Financial Condition for the cash to be paid or received upon settlement. We have determined that it is more preferable to recognize this trading activity on a settlement date basis and recognize firm commitments to purchase and/or sell loans on the date of trade execution due to the extended settlement period for this trading activity. There was no impact to net earnings or total equity as a result of this change in accounting policy.

The following tables reconcile our non-GAAP measures to their respective U.S. GAAP measures. Management believes such non-GAAP measures are useful to investors as they allow them to view our results through the eyes of management, while facilitating a comparison across historical periods. These measures should not be considered a substitute for, or superior to, measures prepared in accordance with U.S. GAAP.
