Hogan Lovells is advising tech giant Dell's cybersecurity company SecureWorks as it moves to float with an estimated value of $1.4bn (£1bn).

Atlanta-based SecureWorks filed what is thought to be the first US tech IPO of the year yesterday (11 April) and is looking to raise $149m (£104m) from its flotation.

Washington-based corporate partner Richard Parrino and North Virginia-based corporate partner Kevin Greenslade are leading the Hogan Lovells team advising SecureWorks.

The partner duo advised Dell in February 2013 on its $24.4bn (£15.5bn) buyout.

Hogan Lovells was among a line-up of top firms that advised the computer manufacturer when founder Michael Dell bought back the PC group, together with private equity group Silver Lake.

On that deal, Parrino and Greenslade were supported by corporate partners Joseph Connelly, Bruce Gilchrist and Eve Howard, finance partner Peter Humphreys and M&A partners Carine Stoick and Brent Singley.

Partner Margaret de Lisser advised on employee benefits, while partner Todd Overman provided advice on government contracts. Paris-based partner Dominique Mendy acted on European labour law aspects.

Davis Polk & Wardwell is advising the underwriters on the SecureWorks flotation.

In October last year, Simpson Thacher & Bartlett, Skadden Arps Slate Meagher & Flom and Wachtell Lipton Rosen & Katz won lead advisory roles as Dell acquired data storage company EMC for $67bn (£44bn).

Dell and EMC have signed an agreement for Dell and its owners, founder Michael Dell and private equity companies MSD Partners and Silver Lake, to acquire EMC.

That transaction is thought to be the largest technology deal ever.
