Old Second Reports Second Quarter 2016 Net Income of $3.8 million

AURORA, IL, July 26, 2016  – Old Second Bancorp, Inc. (the “Company” or “Old Second”) (NASDAQ: OSBC), parent company of Old Second National Bank (the “Bank”), today announced financial results for the second quarter of 2016.  The Company reported net income of $3.8 million for the second quarter of 2016, compared to net income of $4.1 million in  the second quarter of 2015.  The Company’s net income available to common stockholders of $3.8 million, or $0.13 per diluted share for the second quarter of 2016, compared to $3.4 million, or $0.12 per diluted share, in the second quarter of 2015.

Operating Results

· On July 19, 2016, the Company’s Board of Directors declared a cash dividend of 1 cent per share payable on August 9, 2016, to stockholders of record as of July 29, 2016.

· Second quarter 2016 net income available to common stockholders increased by $426,000, or 12.5%, from the second quarter of 2015 and increased approximately 15.7% from the first quarter of 2016.  When compared to the second quarter of 2015, the second quarter 2016 reflects higher net interest income of $427,000.  No release of loan loss reserves was recorded in the second quarter of 2016, as compared to a $2.3 million reserve release in the like 2015 quarter.  Finally, comparing the year over year quarters, the second quarter of 2016 experienced lower noninterest income of $987,000 primarily due to reductions in residential mortgage banking income, and lower noninterest expense stemming from decreases in compensation costs and other real estate owned (“OREO”) expenses.  Noninterest expense of $16.7 million for the second quarter of 2016 was $2.2 million or 11.8% lower than the second quarter of 2015.

· Net interest income in the second quarter of 2016 was $142,000 higher than the first quarter of 2016, and noninterest income was $1.0 million, or 16.0%, higher in the second quarter of 2016 as compared to the first quarter, primarily due to residential mortgage banking income.  Noninterest expense was also higher in the second quarter of 2016 as compared to the prior quarter, which was primarily due to a one-time expense recorded on a debit card contract change.

Asset Quality & Earning Assets

· Nonperforming loans increased to $18.4 million at June 30, 2016, from $14.6 million at December 31, 2015, and $19.3 million at June 30, 2015.  The increase in 2016 was due to 2 relationships secured by commercial real estate which have each lost one large tenant in recent months.  Both borrowers have indicated they are aggressively pursuing new tenants, and one borrower has noted that refinancing is in process with another institution.

· OREO assets decreased in the second quarter to end at $16.3 million on June 30, 2016, compared to $19.1 million at December 31, 2015, and $32.0 million at June 30, 2015. Valuation writedowns continued in the second quarter of 2016 with a quarterly expense of $489,000 compared to $451,000 in the first quarter of 2016.

· Total loans at June 30, 2016, were $1.16 billion, reflecting an increase of $27.4 million when compared to December 31, 2015 and an increase of $2.3 million as compared to June 30, 2015.  Average loans (including loans held-for-sale) for the second quarter of 2016 were $1.15 billion, reflecting an increase of $9.8 million from the fourth quarter of 2015 and a decrease of $2.4 million when compared to the second quarter of 2015.  Loan growth in the 2016 period stems primarily from commercial and industrial loan originations.

· June 30, 2016 available-for-sale securities at fair value totaled $764.6 million, which is an increase of $308.5 million from $456.1 million at December 31, 2015, and $399.8 million balance at June 30, 2015.    The increase is primarily due to the reclassification in the second quarter 2016 of the securities held-to-maturity portfolio to available-for-sale.  This portfolio transfer was completed to allow flexibility to fund loan growth or to restructure the securities portfolio as management deems appropriate.  The total securities portfolio has also increased in the last twelve months by $111.3 million, which is commensurate with deposit and short-term borrowing growth.

Management review of the loan portfolio concluded that neither a loan loss reserve release nor a loan loss provision was appropriate in the second quarter of 2016 or the last quarter of 2015. The second quarter of 2015 reflected a loan loss reserve release of $2.3 million.

1  Interest income from loans is shown on a tax equivalent basis as discussed in the table on page 13 and includes fees of $531,000,  $430,000and $463,000 for the second quarter of 2016, the fourth quarter of 2015 and the second quarter of 2015, respectively.  Nonaccrual loans are included in the above stated average balances. Tax equivalent basis is calculated using a marginal tax rate of 35%.

Net interest and dividend income increased $778,000 for the quarter ended June 30, 2016 as compared to the quarter ended December 31, 2015. Quarterly average earning assets increased $80.3 million from the last quarter of 2015 to a total of $1.93 billion for the period ended June 30, 2016, while yield on earning assets increased 4 basis points.  Year over year second quarter average loans, including loans held-for-sale, decreased $2.4 million, while total earning assets increased $79.0 million for the same period driven by securities growth.  The cost of funds increased by 2 basis points from the prior year end period and 3 basis points from the like period last year.  Total average interest bearing liabilities have increased in all periods presented due to growth in NOW and Savings accounts, as well as securities sold under repurchase agreements and other short-term borrowings.

Of the noninterest income categories, residential mortgage banking income experienced the largest fluctuations on both a linked quarter and year over year basis, as shown above, primarily due to the variability of mortgage servicing rights valuations.  Also, cash surrender value of bank-owned life insurance increased as a result of investment value growth.  Finally, other income for the first quarter of 2016 included approximately $338,000 of various nonrecurring recoveries, and in second quarter 2016, customer swap fee income was $80,000 in excess of the prior quarter.  Excluding these items, the three quarters presented have minimal variation.

1The efficiency ratio shown in the table above is calculated as noninterest expense, excluding OREO expenses, divided by the sum of net interest income on a fully tax equivalent basis, total noninterest income less net gains and losses on securities and includes a tax equivalent adjustment on the increase in cash surrender value of bank-owned life insurance.

Noninterest expense increased $436,000, or 2.7%, on a linked quarter basis primarily as a result of a one-time charge taken on the renewal of a debit card servicing contract of $317,000.  Legal and OREO expenses continue to trend at lower levels than the prior year.  Major expense categories were generally flat or down in the second quarter of 2016 compared to the first quarter of 2016 and the same period in 2015, most notably in salaries and employee benefits.  The FDIC insurance accrual was adjusted in the second quarter of 2016 and will incorporate the FDIC small bank rate change in future quarters.

Nonperforming loans consist of nonaccrual loans, nonperforming restructured accruing loans and loans 90 days or greater past due but still accruing.  The nonperforming loan increase in 2016 was due to 2 relationships secured by commercial real estate which have each lost one large tenant in recent months.  Both borrowers have indicated they are aggressively pursuing new tenants, and one borrower has noted that refinancing is in process with another institution.

Classified loans include nonaccrual, performing troubled debt restructurings and all other loans considered substandard,  as shown below.  Classified loans increased by $2.4 million, or 9.7%, from year end 2015; this increase is due to the two relationships, as discussed in the “Operating Results - Asset Quality & Earning Assets” section above.  Management review of the loan portfolio concluded neither a loan loss provision nor a reserve release was appropriate in the second quarter of 2016.

Non-GAAP Presentations: Management has traditionally disclosed certain non-GAAP ratios to evaluate and measure the Company’s performance, including a net interest margin calculation.  The net interest margin is calculated by dividing net interest income on a tax equivalent basis by average earning assets for the period.  Management believes this measure provides investors with information regarding balance sheet profitability.  Consistent with industry practice, management also disclosed other non-GAAP measures in the discussion above and in the following tables.  The efficiency ratio is discussed in the noninterest expense presentation on page 4.  The tables provide a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.
