FOR IMMEDIATE RELEASE

NORTHERN TRUST CORPORATION REPORTS THIRD QUARTER NET INCOME

OF $178.8 MILLION, EARNINGS PER COMMON SHARE OF $0.73.

(Chicago, October 17, 2012) Northern Trust Corporation today reported third quarter net income per common share of $0.73, up from $0.70 in the third quarter of 2011 and consistent with $0.73 in the second quarter of 2012. Net income was $178.8 million in the current quarter, up 5% from $170.4 million in the prior year third quarter, and down slightly from $179.6 million in the prior quarter. Return on average common equity was 9.6% in the current quarter, compared to 9.5% in the prior year quarter and 9.9% in the prior quarter.

Frederick H. Waddell, Chairman and Chief Executive Officer, commented, “Third quarter performance featured growth in client assets under custody and management of 14% and 16%, respectively, versus last year. Trust, investment and other servicing fees, the largest component of our revenues, grew 8%. The continued headwinds posed by lower interest rates, market activity and volatility moderated these achievements. However, we continued to adapt to these macroeconomic challenges with effective expense management as exemplified by the decline in expenses both year-over-year and sequentially.”

THIRD QUARTER 2012 PERFORMANCE VS. THIRD QUARTER 2011

Net income per common share in the third quarter of 2012 was $0.73 compared to $0.70 per common share in the third quarter of 2011. Net income for the current quarter was $178.8 million compared to $170.4 million in the prior year quarter.

Consolidated revenue of $972.5 million in the current quarter was up slightly from $971.5 million in the prior year quarter. Noninterest income, which represented 75% of revenue, increased $12.2 million, or 2%, to $726.9 million from the prior year quarter’s $714.7 million, primarily reflecting higher trust, investment and other servicing fees, partially offset by lower foreign exchange trading income. Net interest income for the quarter on a fully taxable equivalent (FTE) basis decreased $9.7 million, or 4%, to $256.9 million compared to $266.6 million in the prior year quarter, due to a decline in the net interest margin.

Trust, investment and other servicing fees, which represented 62% of revenue, were $601.9 million in the current quarter, up $46.6 million, or 8%, from $555.3 million in the prior year quarter. The increase primarily reflects new business as well as lower waived fees on money market mutual funds.

Assets under custody and assets under management are the primary drivers of our trust, investment and other servicing fees. The following table provides Northern Trust’s assets under custody and assets under management by business segment.

THIRD QUARTER 2012 PERFORMANCE VS. THIRD QUARTER 2011 (continued)

Trust, investment and other servicing fees in Corporate & Institutional Services (C&IS) increased $23.5 million, or 8%, to $334.4 million in the current quarter from the prior year quarter’s $310.9 million.

	Q3		Q3		Change Q3 2012

Other		23.0		20.0		3.0	15
Total	$	334.4	$	310.9	$	23.5	8	%

Custody and fund administration fees, the largest component of C&IS fees, increased 4%, primarily reflecting new business. C&IS investment management fees increased 13%, reflecting new business and lower waived fees in money market mutual funds. Money market mutual fund fee waivers in C&IS, attributable to persistent low short-term interest rates, totaled $6.5 million in the current quarter, compared to waived fees of $10.1 million in the prior year quarter. Securities lending revenue increased 15%, primarily reflecting higher spreads in the current quarter.

Trust, investment and other servicing fees in Personal Financial Services (PFS) totaled $267.5 million in the current quarter, increasing $23.1 million, or 9%, from $244.4 million in the prior year quarter. The increase in the current quarter primarily reflects new business and lower waived fees in money market mutual funds. Money market mutual fund fee waivers in PFS totaled $10.3 million in the current quarter compared with $19.0 million in the prior year quarter.

Foreign exchange trading income totaled $44.0 million, down $43.2 million, or 49%, compared with $87.2 million in the prior year quarter. The current quarter decrease is attributable to reduced currency market volatility and client volumes.

Other operating income totaled $46.6 million in the current quarter, up $4.1 million, or 10%, from $42.5 million in the prior year quarter, and included a $5.3 million gain on foreign exchange contracts related to hedges of certain investments in foreign currency denominated subsidiaries.

THIRD QUARTER 2012 PERFORMANCE VS. THIRD QUARTER 2011 (continued)

Net interest income for the quarter on an FTE basis totaled $256.9 million, down $9.7 million, or 4%, compared to $266.6 million in the prior year quarter. The decrease reflects a reduction of the current quarter net interest margin to 1.21% from 1.25% in the prior year quarter, primarily reflecting lower yields on earning assets, partially offset by a higher percentage of funding from noninterest-bearing sources. Average earning assets for the quarter were $84.5 billion compared to $84.4 billion in the prior year quarter.

The provision for credit losses was $10.0 million in the current quarter and $17.5 million in the prior year quarter. Net charge-offs totaled $11.9 million for the current quarter resulting from $16.3 million of charge-offs and $4.4 million of recoveries, compared to $28.6 million of net charge-offs in the prior year quarter resulting from $34.9 million of charge-offs and $6.3 million of recoveries. Nonperforming loans and leases decreased $38.5 million, or 13%, from the prior year quarter.

Net interest income for the current quarter on an FTE basis decreased $7.4 million, or 3%, to $256.9 million from $264.3 million in the prior quarter, due to a decline in the net interest margin.

THIRD QUARTER 2012 PERFORMANCE VS. SECOND QUARTER 2012 (continued)

Foreign exchange trading income decreased $15.4 million, or 26%, to $44.0 million compared to $59.4 million in the prior quarter, primarily reflecting reduced currency market volatility and client volumes.

Other operating income in the current quarter totaled $46.6 million, up $12.6 million, or 36%, from $34.0 million in the prior quarter, and includes the $5.3 million gain related to foreign exchange contracts, as well as higher income on employee benefit related assets held in trust by the Corporation and increased credit and leasing related revenue.

Net interest income on an FTE basis in the current quarter totaled $256.9 million, down $7.4 million, or 3%, compared to $264.3 million in the prior quarter. The decrease reflects a lower net interest margin, partially offset by higher average earning assets. The net interest margin decreased to 1.21% in the current quarter from 1.28% in the prior quarter, primarily reflecting a decline in the spread between foreign currency denominated earning assets and interest-bearing deposits. Average earning assets totaled $84.5 billion in the current quarter, up $1.3 billion, or 2%, compared to $83.2 billion in the prior quarter.

The provision for credit losses totaled $10.0 million and $5.0 million in the current quarter and prior quarter, respectively. Net charge-offs totaled $11.9 million for the current quarter resulting from $16.3 million of charge-offs and $4.4 million of recoveries, compared to $3.2 million of net charge-offs in the prior quarter resulting from $16.2 million of charge-offs and $13.0 million of recoveries. Nonperforming loans and leases increased $29.2 million, or 12%, as compared to the prior quarter, primarily reflecting the addition of certain commercial real estate and residential real estate loans. Residential real estate and commercial real estate loans accounted for 66% and 22%, respectively, of total nonperforming loans at September 30, 2012.

Noninterest expense totaled $696.4 million in the current quarter, a decrease of $20.9 million, or 3%, from $717.3 million in the prior quarter. The current quarter and prior quarter include restructuring, acquisition, and integration related charges of $2.9 million and $3.6 million, respectively.

Expense for outside services totaled $126.6 million, a decrease of $7.1 million, or 5%, compared to $133.7 million in the prior quarter. The decrease primarily reflects lower expense for sub-custodian and technical services.

Equipment and software expense totaled $86.0 million in the current quarter, down $13.4 million, or 13%, from $99.4 million in the prior quarter. The prior quarter included a software write-off of $10.5 million.

Total income tax expense was $87.3 million for the current quarter, representing an effective tax rate of 32.8%. Income tax expense was $86.6 million in the prior quarter, representing an effective tax rate of 32.5%.

STOCKHOLDERS’ EQUITY

Total stockholders’ equity averaged $7.4 billion, up 5% from the prior year quarter’s average of $7.1 billion. The increase primarily reflects earnings, partially offset by dividend declarations and the repurchase of common stock pursuant to the Corporation’s share buyback program. During the quarter ended September 30, 2012, the Corporation repurchased 1,068,394 shares at a cost of $49.6 million ($46.45 average price per share). Under our capital plan, which was reviewed without objection by the Federal Reserve in March of 2012, the Corporation may repurchase up to $140 million of common stock after September 30, 2012 through March of 2013. The Corporation is authorized to purchase up to 8.1 million additional shares after September 30, 2012 under its current common stock repurchase authorization.

RECONCILIATION OF REPORTED NET INTEREST INCOME TO FULLY TAXABLE

EQUIVALENT

Net interest income stated on an FTE basis is a non-GAAP financial measure that facilitates the analysis of asset yields. Management believes an FTE presentation provides a clearer indication of net interest margins for comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable, and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on net income. The table below presents a reconciliation of interest income and net interest income prepared in accordance with GAAP to interest income and net interest income on an FTE basis.
