NiSource Reports First Quarter 2009 Results
Reaffirms Annual Earnings Outlook

•

Results In-Line with Business Plan

•

Solid Liquidity Position Enhanced

•

Business Initiatives Continue to Progress

MERRILLVILLE, Ind. — NiSource Inc. (NYSE: NI) today announced net operating earnings (non-GAAP) of $170.2 million, or 62 cents per share, for the three months ended March 31, 2009, compared to $189.4 million, or 69 cents per share, for the first quarter of 2008. Operating earnings (non-GAAP) were $369.4 million, compared to $394.8 million for the same period in 2008.

On a GAAP basis, NiSource reported income from continuing operations for the three months ended March 31, 2009, of $159.3 million, or 58 cents per share, compared with $189.5 million, or 69 cents per share, in the same period a year ago. Operating income was $348.3 million for the first quarter of 2009, compared with $394.9 million in the year-ago period.

NiSource President and Chief Executive Officer Robert C. Skaggs, Jr. noted that, as anticipated, the most significant impact on NiSource’s first quarter earnings results was an increased pension expense of $25 million (or approximately 6 cents per share) related to the deterioration in global securities markets in 2008.

“Despite challenging economic conditions, NiSource produced another solid quarter of core earnings, while continuing to execute key financial, regulatory and infrastructure enhancement initiatives,” Skaggs said. “Our first quarter earnings are consistent with the company’s previously announced net operating earnings (non-GAAP) outlook of $1.00 to $1.10 per share for 2009, and our year-to-date accomplishments serve to underscore our continued commitment to preserving — and executing on — the core elements of our business strategy.”

Skaggs highlighted several of NiSource’s important recent accomplishments:

Enhancing a Solid Liquidity Position

During the past several months, NiSource has successfully executed against its previously announced financing and liquidity plan:

•

On April 9, NiSource’s finance subsidiary, NiSource Finance Corp., closed on a senior unsecured term loan under attractive terms with a syndicate of lenders. The initial February closing of the term loan was at $265 million, and the company was successful in expanding the loan to $385 million at final closing in April under an accordion feature in the financing agreement.

•

On March 9, NiSource Finance Corp. issued $600 million of senior unsecured notes in an underwritten offering. NiSource will use the proceeds from the issuance to complete the refinancing of outstanding debt scheduled to mature in November 2009 and for general corporate purposes, including refinancing a portion of outstanding debt scheduled to mature in November 2010.

•

On April 28, NiSource Finance Corp. announced results of a tender offer for up to $300 million aggregate principal amount of its outstanding notes due in 2010. The aggregate principal amount of notes tendered was approximately $250 million, which will reduce NiSource’s interest expense through November 2010 by approximately $30 million.

•

On March 30, Northern Indiana Public Service Company (NIPSCO) filed an amended petition with the Indiana Utility Regulatory Commission (IURC) seeking permission to issue $120 million of long-term debt to finance the Sugar Creek electric generating facility, which was acquired last year. A hearing before the IURC is scheduled for June 30. NiSource is continuing to evaluate financing opportunities at other operating subsidiaries.

•

Also during the quarter, NiSource business units undertook a number of efforts to manage spending and optimize funds from operations. In connection with these efforts, NiSource Gas Transmission & Storage, on Feb. 27, announced a restructuring plan to better focus on core business activities and increase efficiency, while maintaining safe and reliable service to its customers.

“NiSource’s overall liquidity strategy, including our recent financial and optimization initiatives, not only fully addresses the company’s 2009 debt refinancing requirements but also places us well on our way toward meeting our remaining 2010 refinancing needs of approximately $690 million,” Skaggs said. “In light of the steps we have taken and are continuing to take, I am confident NiSource will maintain a solid liquidity position going forward.”

Skaggs also noted that, on March 5, credit rating agency Standard & Poor’s announced that it had affirmed NiSource’s “BBB-” investment grade corporate credit rating and, notably, revised its outlook to stable from negative. “We appreciate this recognition that NiSource is executing on its comprehensive strategy to maintain financial flexibility and delivering on our core business commitments,” Skaggs said.

Growth, Infrastructure Investments and Regulatory Initiatives Continue to Progress

NiSource’s business units also continued to advance key growth and infrastructure enhancement programs, synchronized with complementary regulatory and commercial initiatives:

•

NIPSCO received a favorable regulatory order on Feb. 18 related to its actions to increase its electric generating capacity and advance its electric rate case. Acting on a settlement reached among NIPSCO and its regulatory stakeholders, the IURC ruled that NIPSCO’s Sugar Creek electric generating plant was “in service” for ratemaking purposes as of Dec. 1, 2008. The IURC also approved the deferral of depreciation expenses and carrying costs associated with the $330 million Sugar Creek investment until such time as the IURC recognizes the plant in the company’s rate base through revised rates.

•

Progress also continued on NIPSCO’s electric base rate case — the company’s first in 20 years. Initial hearings were held in the proceeding in January 2009, and a public hearing on the case was conducted in March. Intervening parties have until May 8 to file testimony. A final round of evidentiary hearings is scheduled for this summer, with the case expected to be resolved, and new electric rates effective, by late 2009 or during the first quarter of 2010.

“Successful resolution of the NIPSCO rate case remains a very high priority for NIPSCO CEO Eileen O’Neill Odum and the entire NIPSCO team this year,” Skaggs said. “While much work remains ahead of us, I am pleased with the progress we are making to establish a solid foundation for NIPSCO and position it to contribute to NiSource’s growth going forward.”

At NiSource’s Gas Transmission & Storage (NGT&S) unit, work also continued on the development of new growth projects and the maximization of value from NiSource’s existing asset base.

•

In southwestern Pennsylvania, NGT&S unit Columbia Gas Transmission began increasing its transportation capabilities to provide market access for an additional 150,000 dekatherms per day (Dth/d) of gas from the Marcellus Shale production area. Specifically, Columbia Gas Transmission is modifying its Waynesburg Compressor Station and parts of its Line 1570 in Allegheny and Washington counties to enable it to transport additional natural gas supplies to market. The initial phase of firm transportation service commenced in the third quarter of 2008, with additional increments scheduled to be placed in service through mid-2010.

•

In conjunction with a March open season, NGT&S unit Columbia Gulf Transmission completed the addition of 95,000 Dth/d of contracted capacity for delivery to the Florida Gas Transmission system near Lafayette, La. The new capacity is in addition to 145,000 Dth/d of capacity already subscribed for delivery to Florida Gas Transmission.

•

On March 25, the Federal Energy Regulatory Commission (FERC) issued a certificate authorizing Columbia Gas Transmission to expand its Ohio storage facilities to meet growing demand for natural gas storage and transportation services in the company’s Mid-Atlantic markets. The Ohio Storage Expansion Project will increase Columbia Gas Transmission’s storage capacity by 6.7 billion cubic feet and enhance daily deliverability from the Weaver and Crawford Storage fields by 100,000 Dth/d. Storage deliveries are scheduled to commence in November of this year. Notably, the FERC authorized market-based rates for the project — the first time that Columbia Gas Transmission has been granted such authority in connection with the expansion of an existing, traditionally cost-based, storage facility.

•

On March 30, Columbia Gas Transmission announced a binding open season for capacity into premium East Coast markets resulting from modifications made to the company’s Easton Compressor Station. The modifications will increase delivery capacity from the Wagoner interconnection point between the Columbia Gas Transmission and Millennium pipeline systems. Through the open season, which closed on April 3, the company received 30,000 Dth/d of binding bids.

•

Construction also continued on two additional NGT&S expansion projects. The Appalachian Expansion Project continues to progress, with service targeted to begin later this year, providing approximately 100,000 Dth/d of new transportation capacity to three key Appalachian Basin producers. Meanwhile, the Eastern Market Expansion — a project that expands Columbia Gas Transmission’s facilities to provide 97,000 Dth/d of additional storage and related transportation services under fully subscribed, 15-year firm contracts — was placed into service April 1.

“The NGT&S team continues to make significant progress in developing and delivering new energy infrastructure projects that will provide enhanced supply access to Eastern and Southeastern market areas,” Skaggs said. “These ongoing infrastructure projects are — and will continue to be — a key contributor to our long-term growth plan.”

Regulatory and commercial initiatives also progressed at NiSource’s gas distribution companies.

•

On March 27, the Maryland Public Service Commission approved a unanimous settlement of Columbia Gas of Maryland’s base distribution rate case filed last year. The rate change, which went into effect on March 31, 2009, will increase annual revenues by approximately $1.2 million.

•

Also in March, the Virginia State Corporation Commission approved Dominion Virginia Power Company’s planned 580-megawatt Bear Garden power station in Buckingham County, Va. Columbia Gas of Virginia will supply natural gas transportation service to the facility following an approximately $50 million expansion of its distribution system. The service is scheduled to begin by the fall of 2010.

•

On April 30, Columbia Gas of Ohio filed an application with the Public Utilities Commission of Ohio (PUCO) to defer pension and other post employment benefit (OPEB) expenses above those currently subject to collection in rates. A similar filing was made by Columbia Gas of Kentucky with the Kentucky Public Service Commission on April 23.

•

Progress also continued on new rate proceedings at two of NiSource’s gas distribution companies. Bay State Gas Co. filed a petition with the Massachusetts Department of Public Utilities on April 16 seeking to increase total annual revenues by $34.6 million, or 6.4 percent, while Columbia Gas of Kentucky is on track to file for a base rate increase later today with the Kentucky Public Service Commission. These proceedings will continue NiSource’s collaborative regulatory approach toward engaging stakeholders in addressing issues related to energy conservation, customer assistance and timely recovery of pension expenses, as well as ongoing infrastructure enhancement investments.

“Synchronization of our significant infrastructure replacement programs and enhancement projects with thoughtful, collaborative regulatory initiatives such as those being undertaken in Massachusetts and Kentucky is a central feature to NiSource’s long-term gas distribution business strategy,” Skaggs said. “Building on last year’s successes in Ohio and Pennsylvania, our gas distribution team continues to make excellent progress in executing on that strategy.”

First Quarter 2009 Operating Earnings — Segment Results (non-GAAP)

NiSource’s consolidated operating earnings (non-GAAP) for the quarter ended March 31, 2009, were $369.4 million, compared to $394.8 million for the same period in 2008. Refer to Schedule 2 for the items included in 2009 and 2008 GAAP operating income but excluded from operating earnings.

Operating earnings for NiSource’s business segments for the three months ended March 31, 2009 are discussed below.

Gas Distribution Operations reported operating earnings for the current quarter of $237.3 million compared to $255.6 million in the first quarter of 2008. Net revenues, excluding the impact of regulatory trackers, increased $5.1 million, primarily attributable to regulatory and service programs including impacts from rate cases at various utilities, partially offset by decreased customer usage and lower off-system sales revenues. Operating expenses, excluding trackers, were $23.4 million higher than the comparable period, reflecting increases in employee and administrative costs, uncollectible accounts, depreciation costs, and outside services. The increase in employee and administrative expenses for all operating segments was driven primarily by increased pension costs that were discussed in NiSource’s 2008 SEC Form 10-K and Feb. 4, 2009 earnings release.

Gas Transmission and Storage Operations reported operating earnings for the current quarter of $111.1 million versus operating earnings of $104.4 million in the first quarter of 2008. The increase resulted primarily from increased net revenues of $11.0 million, primarily attributable to increases in firm capacity reservation fees and the impact of regulatory trackers. The increase in firm capacity reservation fees was the result of higher Columbia Gas Transmission revenue for storage services, new Appalachian Supply interconnects, and incremental revenue from transportation agreements on both Columbia Gulf Transmission and Columbia Gas Transmission. Equity earnings increased by $4.4 million resulting from Millennium Pipeline being in service.

Operating expenses increased by $8.7 million due to higher employee and administrative expenses, environmental costs, and regulatory trackers, partially offset by lower outside services fees and materials and supplies.

Electric Operations reported operating earnings for the current quarter of $26.1 million, compared with $38.0 million in the first quarter of 2008. The decrease resulted from higher operating expenses, partially offset by higher net revenues. Operating expenses increased by $16.2 million due to higher employee and administrative costs, electric generation and maintenance expenses, including expenses associated with the Sugar Creek facility, storm damage repairs, higher depreciation costs and other taxes. These increases were partially offset by lower environmental expenses resulting from an insurance settlement.

Net revenues increased by $4.3 million due to increased residential and commercial margins partially offset by lower industrial and wholesale volumes and margins.

Other Operations reported an operating loss for the current quarter of $1.4 million, compared with a loss of $0.5 million for the first quarter of 2008. The decrease was due to lower net revenues from commercial and industrial gas marketing activities.

Other Items

Interest expense decreased by $1.3 million due to lower short-term interest rates and savings from the $100 million of open market debt repurchases in January 2009, partially offset by incremental interest expense associated with $700 million of debt issued in May 2008 and a partial month of interest expense associated with the $600 million of debt issued in March 2009. Other-net was a loss of $4.2 million compared to a loss of $1.5 million for the first quarter of 2008 as a result of lower interest income. The effective tax rate of net operating earnings for the first quarter 2009 was 38.0% compared to the tax rate of 37.2% for the first quarter of 2008. The increase in the effective tax rate is primarily due to a reduction in estimated Section 199 deductions as a result of lower projected taxable income for 2009, and an increase in tax expense related to AFUDC-Equity and certain depreciation differences.

Income from Continuing Operations (GAAP)

On a GAAP basis, NiSource reported income from continuing operations for the three months ended March 31, 2009, of $159.3 million or 58 cents per share, compared with $189.5 million, or 69 cents per share for the three months ended March 31, 2008. Operating income was $348.3 million for the first three months of 2009 versus $394.9 million in the year-ago period. In addition to the impacts discussed above, the first quarter 2009 GAAP results include a restructuring charge of $19.8 million related to the restructuring of Gas Transmission and Storage Operations. As previously announced, the majority of these charges include costs related to severance and other employee related costs.

Refer to Schedule 1 for a complete list of the items included in 2009 and 2008 GAAP income from Continuing Operations but excluded from net operating earnings.
