Exhibit 99.1

FORMER EXECUTIVES SETTLE LITIGATION WITH DPL

DAYTON, Ohio — May 21, 2007 — DPL Inc. (NYSE: DPL) announced today, subject to court approvals, that Peter H. Forster, its former chairman; Caroline E. Muhlenkamp, its former group vice president and interim chief financial officer; and Stephen F. Koziar Jr., its former president and chief executive officer have agreed to resolve litigation brought by DPL in the Court of Common Pleas, Montgomery County Ohio.  Commenting on the settlement, Glenn Harder, Chairman of the Board of Directors of DPL, said:  “It is appropriate to have this litigation resolved in a manner that provides positive economic value for our shareholders and resolves the litigation with the former executives.  I believe this is clearly a good outcome for DPL.”

As previously reported in DPL’s public filings with the Securities and Exchange Commission, in August 2004 DPL brought a lawsuit against the three former executives asserting, among other claims, that the former executives had breached their fiduciary duties and therefore should forfeit their deferred compensation as well as vested stock based compensation.  The former executives filed counterclaims against DPL and related parties asserting claims based on the former executives’ employment and consulting contracts and various compensation plans.

Under the settlement agreement, the three former executives relinquished all of their claims in this litigation of approximately $134 million, including amounts held in various deferred compensation trusts.  The amounts to be relinquished by the former executives include deferred compensation worth approximately $43 million, a purported 4.8 million stock options with an estimated value of $52 million, claimed bonuses and compensation of $21 million and a claim for attorneys’ fees of approximately $18 million.  The foregoing dollar amounts relating to equity compensation are estimated based upon the May 18, 2007 closing price for DPL common stock.  The former executives will receive $25 million, less all applicable withholding taxes, from existing master trusts. The former executives also will be responsible for paying all of their attorneys’ fees.  In addition, Forster and Muhlenkamp agreed to dismiss their lawsuit against the purchasers of DPL’s financial asset portfolio.

In exchange for the above amounts, the Company will drop all of its claims and expects to report a gain in the second quarter.  A complete accounting analysis of the settlement is underway.  The effect of the settlement at this date is estimated as follows:

·Increase net income by approximately $23 million as a result of reversing previously taken accruals

·Increase total basic earnings per share by approximately $0.22

·Reduce the number of fully diluted shares outstanding by approximately 2.6 million

These estimates exclude the recovery by the Company of legal fees of $14.5 million under a fiduciary insurance policy during the second quarter as well as the ongoing legal fees incurred by the Company since March 31, 2007.

More detailed financial results of the litigation settlement will be provided in the Company’s next public filing with the Securities and Exchange Commission on Form 10-Q for the quarter ending June 30, 2007.
