Unaudited Consolidated Statements of Income for the Company and VUHI for the
three and six months ended June 30, 2003 and 2002 are attached to this filing as
Exhibits 99-1 and 99-2, respectively. Highlighted information is attached as
Exhibit 99-3.

In connection with the "safe harbor" provisions of the Private Securities
Litigation Reform Act of 1995, the Company is hereby filing cautionary
statements identifying important factors that could cause actual results of the
Company and its subsidiaries, including Vectren Utility Holdings, Inc., Indiana

Press Release Excerpts

         Vectren Corporation reported 2003 second quarter earnings of $4.1
         million, or $0.06 per share, compared to net income of $12.5 million,
         or $0.18 per share, for the same period last year. For the six months
         ended June 30, 2003, reported earnings were $59.8 million, or $0.88 per
         share, compared to $58.1 million, or $0.86 per share, for the same
         period in 2002.

         The 2003 second quarter results declined $0.10 per share as compared to
         the same period in 2002 due to milder weather affecting both heating
         and cooling sales and the write-off of two investments, as previously
         announced. Heating weather experienced in the second quarter 2003 was
         9% warmer than the same period last year and cooling sales were reduced
         by weather 51% milder than the same period in 2002. The estimated
         quarter over quarter impact of milder weather was $4.3 million after
         tax, or $0.06 per share.

         The 2003 results include the write-off of the Company's investment in
         BABB International, Inc., an entity that processes fly ash into
         building materials. Charges of $1.9 million, pre-tax and $2.0 million,
         pre-tax were recorded in the second and first quarters, respectively,
         of 2003. The second quarter 2003 also includes the write-off of $2.0
         million pre-tax of the investment in First Mile Technologies, a small
         broadband entity located in Indianapolis, Indiana. The write-off of
         both investments reduced net income for the second quarter by $2.3
         million, or $0.04 per share, and the first six months by $3.5 million,
         or nearly $0.06 per share.

         Operating Review for the Quarter ended June 30

         Utility Group

         Utility earnings for the second quarter 2003 were $1.4 million as
         compared to $8.7 million for the same quarter last year. As noted
         previously, the primary contributors to the decline are electric
         cooling weather that was significantly below normal in the 2003 quarter
         and the write-off of the BABB investment.

         Gas margins were $60.8 million, an increase of $2.5 million over the
         same quarter in 2002. The increase is primarily due to increased late
         payment charges, an increase in Ohio's percent of income payment plan
         (PIPP) rate recovery rider, recovery of customer choice implementation
         costs, recovery of gross receipts and excise taxes on higher gas costs,
         and other items. The increase was partially offset by heating weather
         which was normal and 9% warmer than the prior year period. The
         estimated quarter over quarter pre-tax impact of the warmer weather on
         gas utility margins was approximately $3.3 million. Weather and an
         overall decline in customer usage were the primary factors resulting in
         the 8% decrease in throughput.

         Electric margins were $50.8 million, a decrease of $2.2 million
         compared to the second quarter of 2002. The decrease in electric margin
         was due primarily to the effect of milder cooling weather which was 43%
         cooler than normal and 51% cooler than last year, offset by increased
         margins from wholesale power activities. The estimated quarter over
         quarter pre-tax decrease as a result of the milder weather on electric
         utility margins was approximately $3.9 million. As a result of the mild
         weather, volumes sold to retail and firm wholesale customers decreased
         7%. Non-firm wholesale electric utility margins increased $1.9 million
         to $3.9 million in 2003 compared to 2002.

         Other operating expenses for the second quarter increased $5.1 million
         compared to the same period in the prior year. The increased expenses
         were principally due to higher uncollectible accounts expenses, the
         timing of electric plant maintenance expenditures, and other costs such
         as PIPP and Ohio customer choice costs that are recovered through
         margins.

         Depreciation and amortization increased $3.3 million compared to the
         prior year due to utility plant additions. Since June 30, 2002, the
         Company has placed in service over $100 million in utility plant
         including a new gas-fired electric peaking unit, expenditures for
         implementing a choice program for Ohio gas customers, and other
         upgrades to existing transmission and distribution facilities.

         Taxes other than income increased $0.9 million compared to the prior
         year due primarily to higher gross receipts and excise taxes incurred
         as a result of higher gas prices.

         Other income (expense), net for the utility group decreased $3.0
         million compared to the prior year. The decrease is primarily the
         result of the additional pre-tax charge of $1.9 million taken to
         write-off the BABB investment. In addition, the second quarter of 2002
         includes income from the sale of emission allowances of approximately
         $1.0 million pre-tax that did not recur in 2003.

         Interest expense decreased $1.4 million when compared to the same
         quarter last year. The decrease primarily resulted from lower interest
         rates. This was partially offset by higher outstanding balances due
         primarily to funding of capital expenditures and increased working
         capital requirements resulting from the higher gas prices experienced
         during late 2002 and 2003.

         Non Regulated Group (all amounts following in this section are after
         tax)

         Nonregulated earnings for the second quarter 2003 decreased to $3.4
         million as compared to $4.4 million for the same period last year due
         to the impact of the write-off of the First Mile investment.

         Earnings from Energy Marketing and Services were $2.1 million, a
         decline of $1.5 million from the second quarter of 2002. Gas
         Marketing's contribution was down $2.2 million period over period
         primarily due to the timing of costs and optimization benefits related
         to pipeline contracts. Performance Contracting was up $0.7 million due
         to success in obtaining higher margins and working from a higher
         construction backlog at the end of 2002. Performance Contracting
         results also reflect 100% Vectren ownership during the quarter versus
         67% Vectren ownership in 2002.

         Earnings from Coal Mining were $4.7 million, an increase of $1.8
         million from the second quarter 2002. Mining operations were $0.4
         million and $0.9 million for the 2003 quarter compared to the 2002
         quarter. Net earnings from the investment in Pace Carbon were $3.2
         million and $1.3 million in 2003 and 2002, respectively. Synfuels
         related results, which reflect earnings from the investment in Pace
         Carbon and Synfuels related fees, were $4.3 million and $2.0 million in
         2003 and 2002, respectively. Approximately eight hundred thousand tons
         of coal were mined and an additional three hundred thousand tons were
         brokered. Of that amount, seven hundred thousand tons were sold to the
         utility operations under approved contracts, with the remainder sold to
         third parties. The earnings from mining operations were impacted by
         reduced mining yields.

         Broadband includes the $1.2 million after tax write-off of the First
         Mile investment. The company's investments in SIGECOM and its parent
         Utilicom Networks, LLC, a local broadband provider to Evansville,
         Indiana, had no significant impact on the company's operating results.

         Utility Infrastructure and Other Non Regulated businesses results were
         generally unchanged quarter over quarter.

         Operating Review for the Six Months Ended June 30

         Utility Group

         Utility earnings for the six months ended June 30, 2003 were $48.7
         million in 2003 as compared to $50.7 million for the same period in
         2002, primarily driven by weather that on the year was favorably
         impacted by $5.4 million after tax compared to last year and increased
         wholesale and other margin, offset by the BABB investment write-off of
         $2.3 million after tax and increased other operating costs.

         Gas margins were $205.2 million, an increase of $19.0 million over
         second quarter 2002. It is estimated that weather, 17% colder than the
         prior year and 7% colder than normal, contributed $12.0 million pre-tax
         to the increased margin. The remaining $7.0 million increase is
         primarily attributable to gross receipts and excise taxes, increased
         late payment fees, and recovery of Ohio customer choice implementation
         costs.

         Electric margins were $109.0 million, an increase of $6.7 million over
         2002 primarily due to increased non-firm wholesale power activity
         resulting from price volatility, offset by lower retail sales due to
         milder cooling weather. As a result of the mild weather which was 44%
         cooler than normal and 51% cooler than last year, volumes sold to
         retail and firm wholesale customers decreased 3% with an estimated
         margin impact of $2.9 million pre-tax. Non-firm wholesale margins were
         $12.1 million, an increase of $9.0 million over 2002.

         Other operating expenses increased $10.4 million compared to the prior
         year. The increased expenses were due principally to higher
         uncollectible accounts expense, the timing of electric plant
         maintenance and other costs such as PIPP and customer choice
         implementation costs in Ohio that are recovered through margins.

         Depreciation and amortization increased $5.3 million compared to the
         prior year due to utility plant additions.

         Taxes other than income increased $4.5 million compared to the prior
         year due to higher gross receipts and excise taxes as a result of
         higher gas prices and increased gas volumes sold.

         Other income (expense), net for the utility group decreased $7.0
         million pre-tax compared to the prior year. The decrease is primarily
         the result of the $3.9 million pre-tax write-off of the BABB
         investment, less AFUDC and interest income, and contributions of $1.2
         million pre-tax to low income customer assistance programs resulting
         from the ProLiance settlement. In addition, 2002 amounts include income
         from the sale of emission allowances and other assets totaling $2.2
         million pre-tax.

         Interest expense decreased $2.5 million when compared to last year. The
         decrease primarily resulted from lower interest rates. This was
         partially offset by higher outstanding balances due primarily to
         funding of capital expenditures and increased working capital
         requirements resulting from the higher gas prices experienced during
         late 2002 and 2003.

         Non Regulated Group (all amounts following in this section are after
         tax)

         For the six months ended June 30, nonregulated earnings were $11.9
         million in 2003 as compared to $8.8 million for the same period in
         2002.

         Earnings from Energy Marketing and Services were $10.5 million, an
         increase of $2.3 million over 2002. Gas Marketing's contribution
         increased $1.2 million period over period due to continued realization
         of benefits from the integration of its two gas marketing companies in
         2002 and from opportunities provided by gas price volatility in the
         first quarter. Performance Contracting is up $0.9 million due to the
         higher margins, a large construction backlog at the end of 2002, and
         Vectren's higher ownership percentage in the second quarter of 2003.

         Earnings from Coal Mining were $7.2 million, an increase of $2.3
         million over 2002. Mining operations contributed $0.6 million in 2003
         and $1.4 million in 2002. Net earnings from the investment in Pace
         Carbon, comprised of Synfuel tax credits net of operating losses, were
         $4.8 million and $2.1 million, in 2003 and 2002 respectively. Synfuels
         related results, which reflect earnings from the investment in Pace
         Carbon and Synfuels related fees, were $6.6 million and $3.5 million,
         in 2003 and 2002 respectively. Approximately 1.6 million tons of coal
         were mined and an additional five hundred thousand tons were brokered.
         Of that amount, 1.5 million tons were sold to the utility operations
         under approved contracts, with the remainder sold to third parties.
         Reduced mining yield continues to impact 2003 earnings of the mining
         operations.

         Utility Infrastructure losses increased to $1.2 million from $0.5
         million in 2002 as a result of continued cutbacks from gas distribution
         utility customers which began in the later part of 2002.

         Broadband includes the $1.2 million after tax write-off of First Mile
         in the second quarter of 2003.

         Other nonregulated businesses contributed an after tax loss of $3.5
         million in 2003 as compared to a $4.0 million after tax loss in 2002.
         There was substantial improvement in the losses at the municipal
         broadband consulting company and in the financial asset portfolio.
         However, the 2002 results include a $0.8 million gain in the Haddington
         Ventures portfolio which did not recur in 2003 and therefore offset
         part of this turnaround. Retail marketing operations had a less than
         expected loss of $1.0 million.
