Item 8.01 Other Events.

On January 18, 2006, Mpower Holding Corporation issued the following press release:

Mpower Holding Corporation (AMEX:MPE), the parent company of Mpower Communications Corp., a leading provider of data and voice services to retail and wholesale business customers, today announced that its Board of Directors has approved a stock repurchase program under which Mpower is authorized to acquire up to $10 million of its outstanding common stock in the open market over the next 12 months. The company also announced it intends to adopt a prearranged 10b5-1 stock trading plan and use a portion of the $10 million to repurchase the company’s stock pursuant to that plan. That 10b5-1 plan will be implemented when permitted under company-imposed blackout periods and insider trading law restrictions.

Mpower’s stock repurchase program adopted today allows the company to make share purchases from time to time during its normal trading windows, depending on market conditions, share price and other factors. The 10b5-1 trading plan, when adopted, will allow Mpower to also repurchase shares at times when it otherwise might be prevented from doing so under the insider trading laws or because of self-imposed trading blackout periods.

“The Board’s approval of this program reflects a strong belief in Mpower’s future and is consistent with our belief that our current valuation does not reflect the underlying long-term value of the company,” explained Mpower Chairman and Chief Executive Officer Rolla P. Huff. “We are going to be opportunistic about making share repurchases in the open market from time to time during our normal trading windows. The 10b5-1 program, when adopted, will allow us to consistently purchase shares through prearranged trades without interruption, whether or not we are in a blackout period for any reason.”

The repurchased shares will be held in treasury. As of January 18, 2006, Mpower had 91,546,765 shares of common stock outstanding.
