Adjusted earnings before interest, taxes, depreciation, and amortization increased 18.7% to $11.1 million, from $9.3 million a year earlier.
The company said first-quarter operating results were helped by the Natural Products Expo West show. Penton said that quarterly results also were affected by a $2.4 million charge for executive separation costs and a restructuring charge of $900,000 primarily related to staff reductions.
Pentonâs reporting of its first-quarter results was delayed as negotiations were under way over the terms of Penton Chairman-CEO Thomas L. Kempâs departure. Kemp has agreed to stay on until a replacement is named.
