eOn Communications Reports Third Quarter and Year-To-Date Results

CORINTH, MS (June 13, 2011) – eOn Communications Corporation™ (NASDAQ: EONC) (the “Company”), a leading provider of telecommunications solutions, today reported third fiscal quarter and year-to-date results for the period ended April 30, 2011.

Third quarter revenue increased 57% to $5,561,000 from $3,535,000 in the third quarter of last year, primarily due to the inclusion of Cortelco Systems Puerto Rico revenue in which majority ownership was acquired on June 9, 2010. Net income for the quarter was $131,000 or $0.05 per common share compared to net loss of $47,000 or $0.02 per common share in the quarter ended April 30, 2010. Operating results were favorably impacted by $59,000 of imputed interest income due to the amortization of the difference between the face value of the contingent obligation to the former Cortelco shareholders and the discounted present value of the note payable recorded on the balance sheet. Interest expense of $127,000 was offset by $186,000 of interest income resulting from changes in the estimated timing of future interest payments. Net income from continuing operations for the quarter excluding the impact of the imputed interest income was $72,000 or $0.03 per common share.

Revenue for the nine months was $17,111,000, an increase of 49% compared to $11,455,000 for the nine months ended April 30, 2010. Net loss for the nine months was $321,000 or $0.11 per common share, compared to a net income of $84,000 or $0.03 per common share for the nine months ended April 30, 2010. The net loss for the nine months ended April 30, 2011 included a loss from discontinued operations of $232,000 or $0.08 per common share. For the nine months ended April 30, 2011 excluding the impact of $229,000 in imputed interest expense, net income from continuing operations was $140,000 or $0.05 per common share.

Net loss for the nine months in the Company’s Communications and Services segment was partially offset by net income of $885,000 by the Company’s 100% owed subsidiary, Cortelco Systems Holding Company, and net income of $88,000 by the Company’s majority owned subsidiary, Cortelco Systems Puerto Rico.

Mr. David Lee, chairman of eOn’s Board of Directors noted, “Our favorable results for the quarter reflect the impact of our continuing cost reduction initiatives and we are striving to optimize revenue during these slow economic times.”
