NewStar Reports First Quarter Results

Strong Core Business Performance is Offset By Write-Down of Residential Mortgage-Backed Securities Portfolio




   * $0.2 million of adjusted net income in the first quarter or
     $0.01 adjusted earnings per diluted share

   * $2.4 million net loss in the first quarter or $0.07 net loss per
     diluted share on a GAAP basis

   * Recognized $9.0 million after-tax impairment in residential
     mortgage-backed securities portfolio

   * $2.3 billion of assets in managed loan portfolio, up 12% from
     the fourth quarter

   * Commercial credit quality stable, no loan charge offs

BOSTON, May 3, 2007 (PRIME NEWSWIRE) -- NewStar Financial, Inc. (Nasdaq:NEWS) today reported adjusted net income for the first quarter of 2007 of $0.2 million, or adjusted earnings of $0.01 per diluted share. On a GAAP basis, the company reported a net loss of $2.4 million, or $0.07 per diluted share. Positive operating results were offset by a $14.9 million pre-tax charge ($9.0 million after-tax) to recognize impairment in the company's residential mortgage-backed securities portfolio ("RMBS").

The company also announced that it would discontinue its investment activity in this asset class and manage the disposition of its current portfolio over time to optimize its economic value.

"A severe correction in the RMBS market offset an otherwise strong quarter for our core lending franchise," said Tim Conway, Chairman and Chief Executive Officer. "By writing down our portfolio, discontinuing further investment in this asset class and managing the portfolio to maximize recoveries over time, we believe we are taking appropriate action to reduce our risk, while maximizing the economic value of our holdings. As a result, we will be better positioned for the future. Although we are not pleased by the overall results in Q1, the growth in our core business is encouraging. Excluding the write-down, revenue was up 29% from the prior quarter driven by growth in interest income and fee revenue from asset management and syndications. Volume was strong as we grew our managed assets to nearly $2.3 billion. Commercial credit quality is performing well within expected parameters as our loan portfolio continues to season."

"Adjusted net income" and other non-GAAP financial measures used in this release are defined under "Non-GAAP Financial Measures" on page 5. We have provided a reconciliation between GAAP and adjusted (non-GAAP) measures in the attached financial tables.



 Residential Mortgage-backed Securities Portfolio

   * We recorded a $14.9 million pre-tax charge ($9 million
     after-tax) to recognize an unrealized loss and reduce the
     carrying value of our RMBS portfolio in the first quarter of
     2007.

   * An additional $14.1 million of pre-tax net unrealized holding
     losses was taken as a charge to stockholders' equity through the
     Other Comprehensive Income / Loss account.

   * The carrying value of the RMBS portfolio, net of the unrealized
     holding losses described above, was $101 million, or 5.4% of
     total loans and investments, as of March 31, 2007.

   * The portfolio was comprised of RMBS backed by pools of
     collateral consisting of 1st mortgages (40%), 'closed end' 2nd
     mortgages (20%), home equity lines of credit (13%), and serviced
     residential lot loans (7%), as well as net interest margin
     securities (19%) backed by residual interests of home equity loan
     RMBS.

   * Approximately $29 million, or 29%, of the portfolio, represented
     securities backed by pools of mortgage loans to borrowers which
     have weighted average FICO scores of 700 or better (Prime).

   * Approximately $50 million, or 49%, of the portfolio represented
     securities backed by pools of mortgage loans to borrowers which
     have weighted average FICO scores of between 620 and 700
     (Mid-Prime or Alt A).

   * Approximately $22 million, or 22%, of the portfolio represented
     securities backed by pools of mortgage loans to borrowers which
     have weighted average FICO scores of 620 or lower (Sub-Prime).

   * Approximately 47% of the RMBS portfolio is rated investment
     grade by at least one recognized rating agency.

 Strong Origination Volume

   * Overall origination volume for the quarter was $519 million, of
     which $150 million was syndicated to others, $80 million was sold
     to the New Star Credit Opportunities Fund (NCOF), $11 million was
     originated for the managed CLO and $278 million was retained on
     NewStar's balance sheet.

   * Middle Market Corporate generated approximately 82% of the new
     volume in the quarter, while Commercial Real Estate and
     Structured Products produced 10% and 8%, respectively.

   * We continued to grow our proprietary direct origination platform
     in the first quarter, adding four new senior bankers of six that
     we expect to add in 2007.


 Growth in Loans and Investments

   * Managed loan portfolio increased to $2.3 billion as of March 31,
     2007, an increase of $247 million, or 12%, from $2.0 billion at
     December 31, 2006. Assets managed for the NCOF increased by $99
     million, or 35%, from $283 million as of December 31, 2006 to
     $382 million at March 31, 2007.

   * Gross loans and investments in debt securities held on NewStar's
     balance sheet increased to $1.9 billion as of March 31, 2007, an
     increase of $148 million from $1.7 billion at December 31, 2006.

   * Our business continues to be balanced across industry sectors
     and highly diversified across issuers. As of March 31, 2007, no
     single issuer represented more than 1.2% of our loan portfolio
     and the ten largest issuers comprised approximately 10% of the
     loan portfolio.

   * We continue to be highly selective and focus on senior debt
     products, with 77% of the loan portfolio invested in senior
     secured loans and senior debt investments.

 Net Interest Income / Margin

   * Net interest income before provision for credit losses was $22.0
     million for the first quarter 2007 compared to $15.5 million for
     the fourth quarter 2006 and $8.0 million for the first quarter
     2006.

   * Net interest margin was 4.50% for the first quarter 2007
     compared to 3.82% for the fourth quarter 2006 and 3.85% for the
     first quarter 2006. Adjusted net interest margin was 4.50% for
     the first quarter 2007 compared to 4.50% for the fourth quarter
     2006 and 4.46% for the first quarter 2006.

 Non-Interest Income

   * Non-interest income was $(10.7) million for the first quarter
     2007, a decrease of $14.8 million from $4.1 million in the prior
     quarter. The decrease was due principally to the impairment in
     the RMBS portfolio offset by an increase in asset management fees
     generated by the NCOF.

 Stable Commercial Loan Credit Quality

   * As of March 31, 2007, we did not have any impaired loans and had
     not experienced any loan charge offs.

   * As of March 31, 2007, we had an allowance for credit losses of
     $22.9 million, or 1.40% of loans compared to $20.6 million, or
     1.40%, at December 31, 2006 and $9.4 million or 1.24% at March
     31, 2006. The increase in the allowance for credit losses is due
     to higher loan balances and a slight shift in business mix and
     rating profile.

   * Provision expense was $2.3 million in the first quarter 2007
     compared to $5.9 million in the fourth quarter 2006 and $1.4
     million in the first quarter of 2006.

   * One of our loans with a principal amount of $8.4 million was
     delinquent as of March 31, 2007, representing a 0.51% delinquency
     rate. Subsequent to March 31, 2007, this loan became current.

   * The credit issue with a $10.4 million commercial security that
     we disclosed in our 2006 Form 10-K continues to develop and we
     are evaluating restructuring options.

 Funding

   * During the first quarter, we increased the capacity of our
     credit facilities by $200 million and reduced the cost of funds
     on these facilities.

   * Total cash and equivalents as of March 31, 2007 were $191
     million, of which $131 million was unrestricted.

 Expenses

   * Operating expenses were $13.0 million in the first quarter 2007
     compared to $51.6 million in the fourth quarter 2006 and $7.0
     million for the first quarter 2006. The decrease in operating
     expenses from Q4 was primarily due to a $39.1 million of non-cash
     compensation charge in the fourth quarter of 2006 related to
     restricted stock grants made since our inception as a private
     company including equity awards made in connection with our
     initial public offering.

   * Excluding the write-down, our adjusted efficiency ratio was 38%
     in the first quarter 2007.

Forward-Looking Statements

This release contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact included in this release are forward-looking statements. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance and business. As such, they are subject to material risks and uncertainties.

More detailed information about these factors is described in NewStar's filing with Securities and Exchange Commission (the "SEC"), including Item 1A ("Risk Factors") of our 2006 Form 10-K. NewStar is under no obligation to (and expressly disclaims any such obligation to) update or alter its forward-looking statements, whether as a result of new information, future events or otherwise. NewStar plans to file its Form 10-Q with the SEC on or before May 15, 2007 and urges its shareholders to refer to that document for more complete information concerning NewStar's financial results.

Non-GAAP Financial Measures

References to "adjusted net income" and "adjusted earnings per share" mean net income or earnings per diluted share, respectively, as determined under GAAP, excluding the following items: (i) interest expense and amortization of deferred financing costs on corporate debt, (ii) the call premium and termination fee associated with the termination of our corporate debt, (iii) compensation expense related to restricted stock grants made since our inception as a private company, including equity awards made in connection with the initial public offering and (iv) general and administrative expense incurred related to the initial public offering. GAAP requires that these items be included in net income. NewStar management uses "adjusted net income" and "adjusted earnings per share" to make operational and investment decisions, and NewStar believes that they provide useful information to investors in their evaluation of our financial performance and condition. Excluding interest expense and amortization of deferred financing costs on corporate debt and the call premium and termination fee associated with the termination of our corporate debt eliminates expenses that we do not anticipate incurring in the foreseeable future that make it difficult to assess our core performance and compare our period-over-period results. Excluding compensation expense related to restricted stock grants made since our inception as a private company, including equity awards made in connection with the initial public offering and general and administrative expense incurred related to our initial public offering, eliminates unique expenses that make it difficult to assess our core performance and compare our period-over-period results. A reconciliation of adjusted net income to net income is included in this release.

References to "adjusted net interest margin" mean annualized interest income as determined under GAAP less annualized interest expense as determined under GAAP excluding interest expense and amortization of deferred financing costs on corporate debt, divided by average interest earning assets for the period.

Adjusted return on average assets means adjusted net income divided by average assets for the period. Adjusted return on average equity means adjusted net income divided by average equity for the period. Adjusted efficiency ratio means operating expenses determined in accordance with GAAP less (i) the call premium and termination fee associated with the termination of our corporate debt, (ii) compensation expense related to restricted stock grants made since our inception as a private company, including equity awards made in connection with the initial public offering and (iii) general and administrative expense incurred related to the initial public offering divided by net revenue. Adjusted cost of funds means adjusted interest expense divided by average interest bearing liabilities for the period less the average corporate debt outstanding for the period. The adjusted ratios exclude unique expenses that make it difficult to assess our core performance and compare our period-over-period results.

A reconciliation of our adjusted financial measures to their GAAP equivalents is included on page 9 of this release. NewStar's adjusted financial measures should not be considered as alternatives to financial measures determined in accordance with GAAP and may be different from, or inconsistent with, non-GAAP financial measures used by other companies.
