Item 7.01.  Regulation FD Disclosure

Vectren Corporation (the Company) will meet with certain members of the financial community beginning on Thursday, September 14, 2017. Carl Chapman, Chairman, President and CEO and Susan Hardwick, Executive Vice President and CFO, will provide an overview of the company's utility and nonutility businesses and key strategies for growth.

The accompanying slides to be used in these discussions are attached as exhibits to this filing as Exhibits 99.1.

Vectren Corporation is the parent company of Vectren Utility Holdings, Inc. (Utility Holdings) and Vectren Enterprises, Inc. (Enterprises).  Utility Holdings is the intermediate holding company of the Company's three operating public utilities, and Enterprises is the holding company for the Company's nonutility operations.

Per share earnings contributions of the Utility Group, Nonutility Group, and Corporate and Other are presented and are non-GAAP measures. Such per share amounts are based on the earnings contribution of each group included in the Company’s consolidated results divided by the Company’s basic average shares outstanding during the period. The earnings per share of the groups do not represent a direct legal interest in the assets and liabilities allocated to the groups; instead they represent a direct equity interest in the Company's assets and liabilities as a whole. These non-GAAP measures are used by management to evaluate the performance of individual businesses. In addition, other items giving rise to period over period variances, such as weather, may be presented on an after tax and per share basis.  These amounts are calculated at a statutory tax rate divided by the Company’s basic average shares outstanding during the period. Accordingly, management believes these measures are useful to investors in understanding each business’ contribution to consolidated earnings per share and in analyzing consolidated period to period changes and the potential for earnings per share contributions in future periods. Per share amounts of the Utility Group and the Nonutility Group are reconciled to the GAAP financial measure of basic EPS by combining the two. Any resulting differences are attributable to results from Corporate and Other operations. The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP.

In connection with the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995, the Company is hereby furnishing cautionary statements identifying important factors that could cause actual results of the Company and its subsidiaries, including Utility Holdings, to differ materially from those projected in forward-looking statements of the Company and its subsidiaries made by, or on behalf of, the Company and its subsidiaries.  These cautionary statements are attached as Exhibit 99.2.

The information contained herein and in the attached slides shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended.

Forward-Looking Statements All statements other than statements of historical fact are forward-looking statements made in good faith by the company and are intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. Such statements are based on management’s beliefs, as well as assumptions made by and information currently available to management and include such words as “believe”, “anticipate”, ”endeavor”, “estimate”, “expect”, “objective”, “projection”, “forecast”, “goal”, “likely”, and similar expressions intended to identify forward-looking statements. Vectren cautions readers that the assumptions forming the basis for forward-looking statements include many factors that are beyond Vectren’s ability to control or estimate precisely and actual results could differ materially from those contained in this document. Forward-looking statements speak only as of the date on which our statement is made, and we assume no duty to update them. More detailed information about these factors is set forth in Vectren’s filings with the Securities and Exchange Commission, including Vectren’s 2016 annual report on Form 10-K filed on February 23, 2017.

Financing Utility Investment Long history of high investment-grade credit ratings will continue • Current S&P rating of A- (VVC), Moody’s rating of A2 (VUHI); Both stable Utility funds ~85-90% of Vectren’s dividend; Continue to target utility payout of 70% Appropriate mix of long-term debt and equity as needed • Significant cash flow from operations and enhanced by use of timely recovery through regulatory mechanisms • Nonutility cash flow also to be utilized as available to fund CapEx plan at utility • Appropriate mix of financing to be employed to maintain adequate regulatory capital structure and maintain solid credit metrics • Expectations for the next 5 years (2017-2021): o Cash from operations of $2.0-2.5B o Incremental utility long-term debt of ~$800M; $200M issued in July ‘17 o Transfer of available cash flow from nonutility of $100-200M o 6-8% EPS growth target fully considers likely equity needs as generation investment begins to accelerate  Evaluation of timing and possible use of equity forwards for any needed equity financing is ongoing • Tax reform could impact timing and size of financing needs Financing Goals Remain Unchanged: Strong Balance Sheet & Cap Structures, No Incremental Utility Parent Leverage 20 Vectren | Investor Presentation | September 2017

Corporate Tax Reform Assuming loss of interest deductibility, full expensing of CapEx, and a 20% corporate tax rate: Expect that utility rates will be reset to reflect any reduction in tax expense • Any favorable nonutility impact likely reflected in competitive bidding activity going forward Revaluation of existing deferred taxes would occur at effective date of new tax rate • Utility impacts reflected as amounts due to customer • Nonutility impacts would be favorable at implementation Very little parent co. debt limits recurring exposure to loss of interest deductibility Loss of AMT credit carryforward would be expected at effective date of the new tax rate, partially offset by revaluation of existing nonutility deferred taxes Cash flow benefits from full CapEx expensing when investment ramps up later in the 10-yr forecast period No impact to long-term growth targets expected Tax Reform as Currently Being Discussed, Not Expected to Materially Impact Long-Term Outlook 21 Vectren | Investor Presentation | September 2017

Infrastructure Services (VISCO) General Description of Types of Customer Contracts for Infrastructure Services  Infrastructure Services operates primarily under two types of contracts – blanket contracts and bid contracts. Blanket contracts are ones which a customer is not committed to specific volumes of services, but where we have been or expect to be chosen to perform work needed by a customer in a given time frame (typically awarded on a yearly basis). Bid contracts are ones which a customer will commit to a specific service to be performed for a specific price, whether in total for a project or on a per unit basis (e.g., per dig or per foot). General Description of Backlog for Infrastructure Services  For blanket work, backlog represents an estimate of the amount of gross revenue that we expect to realize from work to be performed in the next 12 months on existing contracts or contracts we reasonably expect to be renewed or awarded based upon recent history or discussions with customers.  For bid work, backlog represents the value remaining on contracts awarded or that we reasonably expect to be awarded, but are not yet completed.  While there is a reasonable basis to estimate backlog, there can be no assurance as to our customers’ eventual demand for our services each year or, therefore, the accuracy of our estimate of backlog. Backlog for Infrastructure Services estimated as follows:  For blanket work, estimated backlog as of 6/30/17 and 6/30/16 is $420 million. The estimate of the amount of gross revenue that we expect to realize from work to be performed in the next 12 months is multiplied by 80% to factor in such unknowns as weather and potential budgetary restrictions of customers.  For bid work, estimated backlog as of 6/30/17 is $340 million compared to $275 million at 6/30/16.  Total estimated backlog as of 6/30/17: $760 million compared to $725 million at 12/31/16 and $695 million at 6/30/16 Estimated Backlog Appendix 38 Vectren | Investor Presentation | September 2017

Use of Non-GAAP Performance Measures and Per Share Measures 54 Appendix Contribution to Vectren's Basic EPS Per share earnings contributions of the Utility Group, Nonutility Group, and Corporate and Other are presented and are non-GAAP measures. Such per share amounts are based on the earnings contribution of each group included in the Company’s consolidated results divided by the Company’s basic average shares outstanding during the period. The earnings per share of the groups do not represent a direct legal interest in the assets and liabilities allocated to the groups; instead they represent a direct equity interest in the Company's assets and liabilities as a whole. These non-GAAP measures are used by management to evaluate the performance of individual businesses. In addition, other items giving rise to period over period variances, such as weather, may be presented on an after tax and per share basis. These amounts are calculated at a statutory tax rate divided by the Company’s basic average shares outstanding during the period. Accordingly, management believes these measures are useful to investors in understanding each business’ contribution to consolidated earnings per share and in analyzing consolidated period to period changes and the potential for earnings per share contributions in future periods. Per share amounts of the Utility Group and the Nonutility Group are reconciled to the GAAP financial measure of basic EPS by combining the two. Any resulting differences are attributable to results from Corporate and Other operations. The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP.

A “safe harbor” for forward-looking statements is provided by the Private Securities Litigation Reform Act of 1995 (Reform Act of 1995).  The Reform Act of 1995 was adopted to encourage such forward-looking statements without the threat of litigation, provided those statements are identified as forward-looking and are accompanied by meaningful cautionary statements identifying important factors that could cause the actual results to differ materially from those projected in the statement.  Certain matters described in Management’s Discussion and Analysis of Results of Operations and Financial Condition are forward-looking statements.  Such statements are based on management’s beliefs, as well as assumptions made by and information currently available to management.  When used in this filing, the words “believe”, “anticipate”, “endeavor”, “estimate”, “expect”, “objective”, “projection”, “forecast”, “goal”, “likely”, and similar expressions are intended to identify forward-looking statements.  In addition to any assumptions and other factors referred to specifically in connection with such forward-looking statements, factors that could cause the Company’s actual results to differ materially from those contemplated in any forward-looking statements include, among others, the following:

• Factors affecting utility operations such as unfavorable or unusual weather conditions; catastrophic weather-related damage; unusual maintenance or repairs; unanticipated changes to coal and natural gas costs; unanticipated changes to gas transportation and storage costs, or availability due to higher demand, shortages, transportation problems or other developments; environmental or pipeline incidents; transmission or distribution incidents; unanticipated changes to electric energy supply costs, or availability due to demand, shortages, transmission problems or other developments; or electric transmission or gas pipeline system constraints.

• New legislation, litigation and government regulation or other actions, such as changes in or additions to tax laws or rates, pipeline safety regulation and environmental laws, including laws governing air emissions, carbon, waste water discharges and the handling and disposal of coal combustion residuals that could impact the continued operation, and/or cost recovery of generation plants and related assets. These compliance costs could substantially change the nature of the Company's generation fleet.

• Catastrophic events such as fires, earthquakes, explosions, floods, ice storms, tornadoes, terrorist acts, physical attacks, cyber attacks, or other similar occurrences could adversely affect the Company's facilities, operations, financial condition, results of operations, and reputation.

• Increased competition in the energy industry, including the effects of industry restructuring, unbundling, and other sources of energy.

• Regulatory factors such as uncertainty surrounding the composition of state regulatory commissions, adverse regulatory changes, unanticipated changes in rate-setting policies or procedures, recovery of investments and costs made under regulation, interpretation of regulatory-related legislation by the IURC and/or PUCO and appellate courts that review decisions issued by the agencies, and the frequency and timing of rate increases.

• Financial, regulatory or accounting principles or policies imposed by the Financial Accounting Standards Board; the Securities and Exchange Commission; the Federal Energy Regulatory Commission; state public utility commissions; state entities which regulate electric and natural gas transmission and distribution, natural gas gathering and processing, electric power supply; and similar entities with regulatory oversight.

• Economic conditions including the effects of inflation, commodity prices, and monetary fluctuations.

• Economic conditions surrounding the current economic uncertainty, including increased potential for lower levels of economic activity; uncertainty regarding energy prices and the capital and commodity markets; volatile changes in the demand for natural gas, electricity, and other nonutility products and services; economic impacts of changes in business strategy on both gas and electric large customers; lower residential and commercial customer counts; variance from normal population growth and changes in customer mix; higher operating expenses; and reductions in the value of investments.

• Volatile natural gas and coal commodity prices and the potential impact on customer consumption, uncollectible accounts expense, unaccounted for gas and interest expense.

• Volatile oil prices and the potential impact on customer consumption and price of other fuel commodities.

• Direct or indirect effects on the Company’s business, financial condition, liquidity and results of operations resulting from changes in credit ratings, changes in interest rates, and/or changes in market perceptions of the utility industry and other energy-related industries.

EXHIBIT 99.2

• The performance of projects undertaken by the Company’s nonutility businesses and the success of efforts to realize value from, invest in and develop new opportunities, including but not limited to, the Company’s Infrastructure Services, Energy Services, and remaining ProLiance Holdings assets.

• Factors affecting Infrastructure Services, including the level of success in bidding contracts; fluctuations in volume and mix of contracted work; mix of projects received under blanket contracts; unanticipated cost increases in completion of the contracted work; funding requirements associated with multiemployer pension and benefit plans; changes in legislation and regulations impacting the industries in which the customers served operate; the effects of weather; failure to properly estimate the cost to construct projects; the ability to attract and retain qualified employees in a fast growing market where skills are critical; cancellation and/or reductions in the scope of projects by customers; credit worthiness of customers; ability to obtain materials and equipment required to perform services; and changing market conditions, including changes in the market prices of oil and natural gas that would affect the demand for infrastructure construction.

• Factors affecting Energy Services, including unanticipated cost increases in completion of the contracted work; changes in legislation and regulations impacting the industries in which the customers served operate; changes in economic influences impacting customers served; failure to properly estimate the cost to construct projects; risks associated with projects owned or operated; failure to appropriately design, construct, or operate projects; the ability to attract and retain qualified employees; cancellation and/or reductions in the scope of projects by customers; changes in the timing of being awarded projects;credit worthiness of customers; lower energy prices negatively impacting the economics of performance contracting business; and changing market conditions.

• Employee or contractor workforce factors including changes in key executives, collective bargaining agreements with union employees, aging workforce issues, work stoppages, or pandemic illness.

• Risks associated with material business transactions such as acquisitions and divestitures, including, without limitation, legal and regulatory delays; the related time and costs of implementing such transactions; integrating operations as part of these transactions; and possible failures to achieve expected gains, revenue growth and/or expense savings from such transactions.

• Costs, fines, penalties and other effects of legal and administrative proceedings, settlements, investigations, claims, including, but not limited to, such matters involving compliance with federal and state laws and interpretations of these laws.

More detailed information about these factors is set forth in Vectren's filings with the Securities and Exchange Commission, including Vectren's 2016 annual report on Form 10-K filed on Feb. 23, 2017.
