Exhibit 99.1

JMP GROUP REPORTS THIRD QUARTER 2010 FINANCIAL RESULTS

SAN FRANCISCO, October 27, 2010 — JMP Group Inc. (NYSE: JMP), an investment banking and alternative asset management firm, reported financial results today for the quarter ended September 30, 2010.

“JMP produced better-than-expected operating earnings for the third quarter, despite a number of challenges,” said Joe Jolson, chairman and chief executive officer of JMP Group. “At JMP Securities, investment banking revenues were above plan, while our brokerage revenues fell short of expectations primarily due to a dramatic industry-wide slowdown in institutional equities trading activity. Harvest Capital Strategies had a flattish quarter on its invested capital but benefitted from better-than-expected incentive fee income in its REIT advisory business. JMP Credit had another good quarter, driven by continued loan sale gains and the distribution of excess cash flow from Cratos CLO I. While we would expect some level of loan sale income to continue for the foreseeable future, it is difficult to predict the timing of loan sales. Assuming business conditions remain stable, we would hope to continue to generate an annual after-tax return of at least 10% on our adjusted tangible book value.”

Revenues

Investment Banking

Investment banking revenues were $12.3 million, an increase of 18.7% from $10.4 million for the third quarter of 2009. For the nine months ended September 30, 2010, investment banking revenues were $28.4 million, an increase of 13.3% from $25.1 million for the nine months ended September 30, 2009.

The company executed 16 investment banking transactions during the quarter, compared to 17 during the third quarter of 2009.

Private placement fee revenues amounted to $5.1 million, up from $1.3 million for the third quarter of 2009, as the company executed five private placements, versus two a year prior. Strategic

Asset management-related fee revenues include asset management fees as well as certain fee revenues (in particular, asset management fundraising fees generated by JMP Securities, loan fees, and revenues from fee-sharing arrangements with other asset managers) reported in JMP Group’s financial statements as other income. Fee revenues classified as other income were $0.3 million and $0.2 million for the third quarters of 2010 and 2009, respectively, and $1.1 million and $1.2 million for the nine months ended September 30, 2010 and September 30, 2009, respectively.

Client assets under management totaled $1.1 billion at both June 30, 2010 and September 30, 2009.

Principal transactions primarily include direct investments made by JMP Group as well as investments by the company in funds managed by Harvest Capital Strategies.

For the quarter, equity investments and investments by JMP Group in its hedge funds produced net realized and unrealized gains of $1.3 million, compared to net realized and unrealized gains of $3.7 million for the third quarter of 2009. In addition, an investment in publicly traded New York Mortgage Trust, Inc. produced an unrealized loss of $0.2 million, compared to an unrealized gain of $2.3 million for the third quarter of 2009.

Gain on Sales and Payoffs of Loans and Loan Loss Provision

JMP Credit realized gains of $7.0 million due to the sale or payoff of 17 of the loans in its portfolio, compared to $6.7 million due to the sale or payoff of six loans during the third quarter of 2009. For the nine months ended September 30, 2010, realized gains amounted to $26.2 million as a result of the sale or payoff of 49 loans. At September 30, 2010, 39 loans with an aggregate par value of $173.2 million and an associated liquidity discount of $51.6 million remained from the portfolio acquired by JMP Credit in April 2009.

A loan loss provision of $0.5 million was recorded for the quarter, of which $0.3 million was with regard to an impaired direct investment by JMP Group and $0.2 million was with regard to performing loans as a general reserve at JMP Credit. For the third quarter of 2009, a loan loss provision of $1.4 million was recorded with regard to impaired loans at JMP Credit.

At September 30, 2010, gross impaired loans totaled $14.0 million, or 3.2% of gross loans outstanding, compared to $24.4 million, or 5.5% of gross loans outstanding, at June 30, 2010 and $93.6 million, or 19.9% of gross loans outstanding, at September 30, 2009. With regard to impaired loans at September 30, 2010, discounts and reserves (including credit discounts, liquidity discounts and allowances for loan losses) equaled $11.9 million, or 84.5% of gross impaired loans outstanding. With regard to performing loans at September 30, 2010, discounts and reserves (including liquidity discounts, allowances for loan losses and deferred loan fees) equaled $55.7 million, or 13.1% of gross performing loans outstanding.

Net Interest and Net Dividend Income

Net interest income equaled $3.0 million, compared to $3.7 million for the third quarter of 2009, and net dividend income totaled $0.4 million, versus $0.8 million for the third quarter of 2009. For the nine months ended September 30, 2010, net interest income was $11.0 million, compared to $6.7 million for the nine months ended September 30, 2009, and net dividend income was $1.5 million, versus $1.8 million for the nine months ended September 30, 2009.

For the quarter and nine months ended September 30, 2010, unscheduled principal prepayments enhanced the yield on loans at JMP Credit and contributed $0.9 million and $3.6 million of net interest income, respectively. JMP Credit did not exist prior to April 2009, which partially accounts for the significant difference in net interest income for the nine months ended September 30, 2010 and September 30, 2009.

Expenses

Compensation and Benefits

Compensation and benefits expense was $19.4 million, compared to $29.3 million for the third quarter of 2009. For the nine months ended September 30, 2010, compensation and benefits expense was $65.5 million, compared to $70.8 million for the nine months ended September 30, 2009. Of the amounts recorded for the quarter and nine months ended September 30, 2010, non-cash compensation expense attributable to restricted stock units, or RSUs, granted in connection with JMP Group’s May 2007 initial public offering was $0.3 million and $2.2 million, respectively, while such expense attributable to RSUs granted thereafter was $0.4 million and $0.8 million, respectively.

As a percentage of total net revenues, compensation and benefits expense was 59.2%, compared to 70.3% for the third quarter of 2009, and was 65.0% for the nine months ended September 30, 2010, compared to 68.5% for the nine months ended September 30, 2009. Pro forma compensation and benefits expense (which excludes the cost of RSU grants) was 57.0% of total net revenues, compared to 67.3% for the third quarter of 2009, and was 62.0% for the nine months ended September 30, 2010, compared to 64.8% for the nine months ended September 30, 2009.

Non-Compensation Expense

Non-compensation expense was $8.7 million, compared to $5.9 million for the third quarter of 2009. For the nine months ended September 30, 2010, non-compensation expense was $22.2 million, compared to $17.5 million for the nine months ended September 30, 2009. Contributing to non-compensation expense for the quarter and nine months ended September 30, 2010 was a one-time impairment charge of $2.8 million recorded in connection with the purchase of an asset management contract during the quarter. For more information regarding the acquisition and subsequent charge, please see the section below titled “Purchase of CLO Management Contract.”

As a percentage of total net revenues, non-compensation expense was 26.7% for the quarter, compared to 14.0% for the third quarter of 2009, and 22.0% for the nine months ended September 30, 2010, compared to 17.0% for the nine months ended September 30, 2009. Excluding the one-time impairment charge of $2.8 million, the adjusted non-compensation expense ratio was 18.3% for the quarter and 19.3% for the nine months ended September 30, 2010.

Purchase of CLO Management Contract

On June 11, 2010, JMP Capital, a subsidiary of JMP Group, agreed to purchase the collateral management contracts for two collateralized loan obligations, or CLOs, from Princeton Advisory Group, Inc. for up to $5.0 million. The transfers of the contracts were subject to the receipt of certain consents and other conditions. On September 8, 2010, JMP Capital completed the purchase of one of the two management contracts for $3.8 million, and the contract was transferred to JMP Credit Advisors. However, since a single investor had previously acquired control of the right to transfer the management contract without cause at any time with 90 days’ notice, JMP Group recorded an impairment charge of $2.8 million for the quarter. JMP Capital has since restructured the transaction to provide JMP Group with indemnity from the seller in the amount of $2.6 million, which is collateralized by certain assets and $1.0 million in cash. The indemnity amortizes over a period ending in February 2013, with the cash portion amortizing last, over the final year of the indemnity period. JMP Credit Advisors has not been given notice that the management contract will be transferred to another manager and, as long as JMP Credit Advisors remains the manager, it will continue to earn management fees from the CLO.

Share Repurchase Activity

During the quarter ended September 30, 2010, JMP Group repurchased a total of 168,739 shares of its common stock at an average price of $6.48 per share, or $1.1 million in aggregate.

Book Value per Share

At September 30, 2010, JMP Group’s tangible book value per share was $5.62, compared to $5.65 at June 30, 2010 and $5.54 at September 30, 2009. Adjusting book value to reflect the net liquidity discount on JMP Credit’s loan portfolio and asset-backed securities issued, JMP Group’s adjusted tangible book value per share at September 30, 2010 would have been $4.68, as indicated by the reconciliation below.

Non-GAAP Financial Measures

In addition to the GAAP financial results presented in this press release, JMP Group presents the non-GAAP financial measures discussed below. These non-GAAP measures are provided to enhance investors’ overall understanding of the company’s current financial performance. Additionally, company management believes that this presentation enables meaningful comparison of JMP Group’s financial performance in various periods. However, the non-GAAP financial results presented should not be

considered a substitute for results that are presented in a manner consistent with GAAP. A limitation of the non-GAAP financial measures presented is that the adjustments concern expenses or gains that JMP Group expects to continue to recognize; the adjustment of these items should not be construed as an inference that these expenses or gains are unusual, infrequent or non-recurring. Therefore, company management believes that both JMP Group’s GAAP measures of its financial performance and the respective non-GAAP measures should be considered together. The non-GAAP measures presented herein may not be comparable to similarly titled measures presented by other companies.

Operating Net Income

Operating net income is a non-GAAP financial measure that (i) reverses stock-based compensation expense related to equity awards granted both at the time of JMP Group’s May 2007 initial public offering and thereafter, (ii) excludes the net amortization of discounts on loans held and asset-backed securities issued by JMP Credit, (iii) excludes net unrealized gains and losses on strategic equity investments, and (iv) assumes an effective tax rate of 42%. This methodology differs from that employed by JMP Group in periods prior to the second quarter of 2010, when operating net income was defined as excluding only stock-based compensation expense related to the company’s IPO. As now calculated, in particular, operating net income adjusts for:

A reconciliation of JMP Group’s net income to the company’s operating net income for the quarter and nine months ended September 30, 2010 and for comparable prior periods is set forth below.

Company management has utilized operating net income on a total and per share basis, adjusted in the manner described above, as an additional device to aid in understanding and analyzing JMP Group’s financial results for the periods presented. Management believes that operating net income provides useful information by excluding or including certain items that may not be representative of the company’s core operating results or business outlook. Management also believes that operating net income is a useful measure because it allows for a better evaluation of the performance of JMP Group’s ongoing business and facilitates a meaningful comparison of the company’s results in a given period to those in prior periods and future periods.

Cautionary Note Regarding Quarterly Financial Results

Due to the nature of its business, JMP Group’s quarterly revenues and net income may fluctuate materially depending on: the size and number of investment banking transactions on which it advises; the timing of the completion of those transactions; the size and number of securities trades which it executes for brokerage customers; the performance of its asset management funds and inflows and outflows of assets under management; gains stemming from sales of or prepayments on, or losses stemming from defaults on, loans underlying the company’s collateralized loan obligation; and the effect of the overall condition of the securities markets and economy as a whole. Accordingly, revenues and net income in any particular quarter may not be indicative of future results. Further, JMP Group’s compensation expense is generally based upon revenues and can fluctuate materially in any particular quarter depending upon the amount and sort of revenue recognized as well as other factors. The amount of compensation and benefits expense recognized in any particular quarter may not be indicative of such expense in a future period. As a result, the company suggests that annual results may be the most meaningful gauge for investors in evaluating the performance of its business.
