Acquisitive internet service provider Verio Inc has filed with the Securities and Exchange Commission for an initial public offering of common shares. The Englewood, Colorado company did not specify in the filing how many shares it would be offering or a target price for the shares, but did say the IPO could be worth up to $100m. Underwriters for the offering will be Salomon Smith Barney Inc, Credit Suisse First Boston and Donaldson, Lufkin & Jenrette Securities Corp. The stock would trade on the Nasdaq National market under the symbol VRIO. Verio, which has acquired more than 30 smaller ISPs since 1996, says it will use the proceeds from the IPO to further its goal of being the dominant national provider of enhanced internet services to small and medium-sized businesses. The company indicates in the SEC filing that it will continue to consolidate its market by acquiring more local and regional ISPs. The company also says it is considering a private placement of $100m in senior notes. For 1997, Verio recorded a net loss of $46.3m on revenue of $35.7m
