Loan Growth – New funded loan volume was approximately $319 million in the second quarter compared to $147 million in the prior quarter and $205 million in the second quarter of the prior year.

Revenue Growth – Consolidated revenue grew 11% from the prior quarter, but decreased on a risk-adjusted basis¹ by 4% as the impact of wider margins was offset by higher provision expense.

Net Interest Margin – Net interest margin widened to 4.68% for the second quarter from 4.11% in the prior quarter due primarily to recognition of deferred loan income in connection with the resolution of problem loans and higher deferred loan fee amortization associated with an elevated level of prepayments.

Asset Quality – NPAs decreased by 33%, or almost $30 million from the prior quarter and non-accruing loans fell to 2.5% of consolidated loans due primarily to the resolution of legacy workouts. Provision for credit losses increased $3.6 million from the prior quarter, reflecting the impact of the resolution of certain problem loans.

Funding – Refinanced $100 million of higher cost debt through new $200 million institutional term debt financing rated BB- by S&P.

New Managed Fund – Formed a new managed credit fund to co-invest in middle-market commercial loans originated by NewStar. The fund is expected to be $300 million when fully invested and its financial results are now reported on a consolidated basis in NewStar’s financial statements in accordance with GAAP².

Risk-adjusted revenue is a non-GAAP measure calculated as the sum of net interest income after provision for credit losses and non-interest income. See “Non-GAAP Measurements” at the end of this press release and page 13 for reconciliation of non-GAAP to GAAP measurements.

The Arlington Fund is a variable interest entity (“VIE”) for which NewStar is deemed to be the primary beneficiary. As a result, these interim condensed consolidated financial statements include the financial statements of NewStar and the Arlington Fund in accordance with GAAP.

Net Income excluding the results of the new Arlington Fund is a non-GAAP measure. See “Non-GAAP Measurements “ at the end of this press release and page 13 for reconciliation to GAAP net income.

In April 2013, NewStar formed a new managed credit fund, NewStar Arlington Fund LLC (“Arlington Fund” or the “Fund”), in partnership with an institutional investor, to co-invest in middle market commercial loans originated by NewStar’s Leveraged Finance lending group. The Fund had $210 million of capital commitments from debt and equity investors at June 30, 2013 and is expected to grow to $300 million of assets under management after it is fully invested.

NewStar retains a minority ownership interest in the Arlington Fund and manages the Fund’s activities with full discretion over its investment decisions. NewStar also participates as a lender in a warehouse line of credit used by the fund to partially finance its loan investments.

The Arlington Fund is treated as a variable interest entity (“VIE”) under GAAP and NewStar is deemed its primary beneficiary. As a result, NewStar is required to consolidate the Fund’s results of operations and financial position.

NewStar’s ownership interest and loan receivable due from the Arlington Fund are eliminated upon consolidation.

Due to its treatment as a VIE, in addition to other facts and circumstances, the Arlington Fund’s membership interests, representing equity ownership in the Fund, are characterized as debt in NewStar’s consolidated financial statements under GAAP and the Fund’s financial results include interest expense related to the membership interest debt based on an imputed interest rate.

Loans managed for the benefit of the Arlington Fund and consolidated into NewStar’s results were $85 million as of June 30, 2013. Borrowings under the Fund’s warehouse credit facilities were approximately $51 million and the Fund’s membership interests characterized as debt in accordance with GAAP were $22 million at June 30, 2013. The net results (after-tax) of the Fund included in NewStar’s financial statements as a consolidated VIE were $0.1 million, or less than $0.01 per share in the second quarter of 2013.

Total new funded loan volume was approximately $319 million in the second quarter compared to $147 million in the prior quarter and $205 million in the second quarter of the prior year. Higher volumes reflected an increase in demand for acquisition financing from financial sponsors amid a pickup in M&A activity following a slow first quarter.

The managed loan portfolio remained steady at $2.4 billion as of June 30, 2013 approximately equal to March 31, 2013 as new funded loan origination was largely offset by loan run-off from scheduled amortization and an elevated level of prepayments of existing loans.

Consolidated loans increased by 1.2% from the prior quarter and 3.0% since the end of 2012, reflecting stronger new loan volume in the second quarter and the consolidation of managed fund assets, which was partially offset by an elevated level of pre-payments.

Excluding the $85 million of loans in the Arlington Fund, the owned loan portfolio decreased slightly from the prior quarter to $1.8 billion as of June 30, 2013 as run-off from scheduled amortization and prepayments of existing loans exceeded new funded loan origination.

The Leveraged Finance loan portfolio, excluding the $85 million of loans in the Arlington Fund, decreased by $32 million during the second quarter of 2013 to approximately $1.5 billion, while asset-based loans and leases in our Business Credit portfolio declined $3.6 million to $201 million.

Assets managed for third party institutional investors, including the Arlington Fund, remained steady at $531 million at June 30, 2013 as the expected run-off of assets managed in the NewStar Credit Opportunities Fund was offset by growth in assets managed for the new Arlington Fund.

Asset-based lending and equipment finance business lines originated approximately $9 million in the second quarter of 2013, or 3% of new loan volume retained on the balance sheet.

Real estate loans decreased by $27 million, or 18.1%, during the quarter to $122 million, or 6.3% of consolidated loans.

The owned loan portfolio (excluding the Arlington Fund) remained balanced across industry sectors and highly diversified by issuer. As of June 30, 2013, no outstanding borrowings by a single obligor represented more than 1.5% of total loans outstanding, and the ten largest obligors comprised approximately 10.3% of the loan portfolio.

Net interest income increased by approximately $4.2 million to $25.2 million for the second quarter of 2013 compared to $21.0 million for the first quarter of 2013 and $21.4 million in the second quarter of 2012.

The portfolio yield increased to 7.33% in the second quarter of 2013 compared to 6.50% in the prior quarter, and 6.35% in the second quarter of 2012. The increase to both net interest income and portfolio yield was due primarily to the recognition of deferred interest income on problem loans resolved during the quarter, higher amortization of deferred loan fees related to an elevated level of prepayments and the consolidation of interest income from the Arlington Fund.

Adjusting for the negative impact of non-accruing loans on a non-GAAP basis, the loan portfolio yield would have been 23 bps higher, or 7.56%.

Net interest margin widened to 4.68% for the second quarter of 2013 compared to 4.11% for the first quarter of 2013 as growth in interest income of $5.7 million in the quarter exceeded a $1.4 million increase in interest expense. As noted above, the growth in interest income was due primarily to higher amortization of deferred loan fees associated with the increase in loan prepayments during the second quarter and the recognition of deferred interest income, as well as growth in consolidated loans. The increase in interest expense reflected higher average borrowings due primarily to the completion of a new corporate debt issuance and the consolidation of the Arlington Fund’s debt.

Non-interest income was $1.5 million for the second quarter of 2013, down from $3.1 million for the first quarter of 2013, and $1.8 million for the second quarter of 2012. The change from the first quarter was due primarily to a decline in value of an equity position retained in connection with a restructuring of an impaired loan. There were no gains on debt repurchases during the first six months of 2013, or in the second quarter of 2012.

Other non-interest income in the second quarter of 2013 consisted primarily of $0.7 million of asset management income and $0.5 million of unused fees on revolving credit commitments. It also included approximately $0.6 million of revenue related to OREO currently being managed by the Company, which, prior to 2013, was reported net of related expenses and is now recognized on a gross basis in the Company’s financial results.

Operating expenses decreased slightly by $0.1 million to $12.8 million in the second quarter of 2013 compared to $12.9 million in the first quarter of 2013 due to lower compensation, general and administrative expenses, partially offset by the recognition of

$0.9 million of operating expense related to OREO currently being managed by the Company, which, prior to 2013, was reported net of related revenue as part of non-interest income and is now recognized as an expense on a gross basis in the Company’s financial results.

Operating expenses excluding non-cash equity compensation⁴ were $11.6 million in the second quarter of 2013, or 2.1% of average assets on an annualized basis, compared to $11.3 million in the prior quarter.

The efficiency ratio excluding non-cash equity compensation⁵ in the second quarter of 2013 was 43.9% compared to 47.1% in the prior quarter.

The Company had 103 full-time employees as of June 30, 2013, equal to March 31, 2013.

Deferred income taxes decreased to $32.1 million as of June 30, 2013 compared to $40.9 million as of March 31, 2013 due primarily to the vesting of performance-based equity awards and a decrease in the allowance for credit losses, as well as the related timing differences of when credit costs are recognized according to GAAP and when they are excluded for income tax.

Approximately $20.4 million and $8.3 million of the deferred tax asset as of June 30, 2013 were related to our allowance for credit losses and equity compensation, respectively.

Total credit costs (including provision for credit losses and losses on OREO or interests retained in connection with workouts of impaired loans) in the second quarter of 2013 increased by $5.5 million to $6.2 million from $0.7 million in the prior quarter.

Specific provision expense was approximately $6.5 million in the second quarter of 2013, up from $0.4 million in the first quarter of 2013. The establishment of a new specific reserve for one loan resulted in a corresponding $2 million reduction in the general allowance for credit losses.

The allowance for credit losses was $39.0 million, or 2.07% of consolidated loans and approximately 83% of NPLs, at June 30, 2013, compared to $45.5 million, or 2.50% of loans and approximately 60% of NPLs, at March 31, 2013.

Non-performing assets decreased by $29.2 million, or 33%, from the prior quarter. Three assets totaling $26.1 million returned to performing status, two legacy loans totaling $8.6 million were placed on non-accrual status, and charge-offs on non-performing assets totaled $8.8 million.

At June 30, 2013, loans with an aggregate outstanding balance of $46.9 million (net of charge-offs), or 2.49% of consolidated loans, were on non-accrual status compared to loans with an aggregate outstanding balance of $76.3 million (net of charge-offs), or 4.19% of loans at March 31, 2013. Non-performing assets, net of charge-offs, specific reserves and other adjustments were $60.1 million, or 3.17% of consolidated loans and 44% of their aggregate face amount, as of June 30, 2013.

Refinanced $100 million of existing corporate debt through a new $200 million institutional term loan by amending and restating key terms of the existing note agreement on May 13, 2013 to reduce cost, extend maturity and provide additional capital. The loan was syndicated among a group of institutional lenders.

Operating expenses excluding non-cash equity compensation is a non-GAAP measure. See “Non-GAAP Measurements” at the end of this press release and page 13 for reconciliation of non-GAAP to GAAP measurements.

Efficiency ratio excluding non-cash equity compensation is a non-GAAP measure. See “Non-GAAP Measurements” at the end of this press release and page 13 for reconciliation of non-GAAP to GAAP measurements.

The loan was rated BB- by Standard & Poor’s and NewStar was assigned a BB- corporate rating with a Stable outlook in connection with the transaction.

Balance sheet leverage increased to 2.73x as of June 30, 2013 from 2.44x at March 31, 2013 due primarily to the corporate debt issuance and the consolidation of the Arlington Fund’s debt.

Added substantial liquidity with total cash and equivalents as of June 30, 2013 of $313.3 million, of which $83.4 million (excluding cash at the Arlington Fund) was unrestricted. Unrestricted cash increased from approximately $27.6 million at June 30, 2013 and restricted cash increased from approximately $141.0 million to $228.3 million due primarily to timing differences. Cash at the Arlington Fund totaled $1.6 million.

Book value per share was $12.39 at the end of the second quarter of 2013, up $0.20 from $12.19 at the end of the prior quarter and up $0.70 from $11.69 at the end of the second quarter of 2012 primarily due to net income, the forfeiture of employee restricted shares to satisfy their personal tax liability upon vesting, and the amortization of equity compensation into stockholders’ equity. During the second quarter of 2013, employees forfeited 0.9 million shares to satisfy their tax liability in connection with the vesting of restricted shares.

Average diluted shares outstanding were 52.6 million shares for the quarter, which was down from 53.3 million shares for the prior quarter. Total outstanding shares at June 30, 2013 were 48.6 million, down from 49.3 million as of March 31, 2013.
