New acquisition strengthens LANDesk’s market leadership and signals accelerated growth

SALT LAKE CITY – April 24, 2012 – LANDesk Software, a global leader in systems lifecycle management, endpoint security and IT service management, today announced the acquisition of Managed Planet. The company has unique technologies in the areas of IT asset management, business to business connectors, hardware discovery, reporting and asset analytics. LANDesk previously licensed this technology as part of its LANDesk® Data Analytics product. Managed Planet is located in Dallas, Texas and financial terms of the transaction were not disclosed.

This acquisition is the fifth since LANDesk spun-out of Intel in 2002 and the first for LANDesk since becoming a stand-alone business again in September of 2010. As a stand-alone company, LANDesk has achieved significant growth and expanded its product portfolio while achieving record levels of profitability. This acquisition represents a first step in the next phase of LANDesk’s growth strategy and further strengthens LANDesk’s position as a market leader in IT end-user management.

“Acquisitions represent an important component of our growth strategy and this announcement marks a shift to accelerated growth for LANDesk,” said Bob Macfarlane, LANDesk’s Vice President of Corporate Development. “LANDesk has achieved its core goals since becoming an independent company and our strong financial performance fuels plans for future acquisitions.”

LANDesk will continue to sell its version of LANDesk Data Analytics as add-on options to its systems and security management products. This technology allows organizations to achieve additional benefits by expanding the management of hardware devices, including printers, with in-depth reporting and analytic capabilities. This acquisition will enable LANDesk to more quickly localize all Managed Planet offerings while expanding availability through LANDesk global channels.

LANDesk asset management solutions help IT organizations reduce hardware and software asset management cost. LANDesk Data Analytics along with LANDesk Software License Monitoring and Asset Lifecycle Manager combine to provide a comprehensive picture of the asset status, while offering easy integration into procurement systems.

One of the things that contributed to our success is that we try to work closely with our advisory committee, which is made up of our larger limited partners. Before we start fundraising, we make sure these investors know what we’re doing. We share any management changes that might take place, we reassure them that there isn’t any strategy drift. We’re really making sure that this group of investors is really up to speed, so that even before we go to market, we’ve got 60 to 70 percent of the money raised. If those nine people are not going to sign up for our fund, we better not go to market. You have to take your core investors and be partners with them because it’s sufficiently hard to raise money right now. If they don’t support you, you just can’t raise money.

Since Thoma Bravo has so many longstanding investors, do you feel the need to get new blood into your funds?

Yes, for several reasons. First of all, it’s sometimes harder for existing investors to give you more money than they did last time. And if you want the fund to be a bit bigger, you need new investors. Also, you occasionally run into situations where certain investors are over-allocated to private equity and they can’t make any new commitments when you are raising your fund. So you’ve always got to be adding new people for occasions like that. And you want to keep growing and building new relationships and getting new perspectives. You just don’t want to be thinking of yourself as a closed group.

You don’t use placement agents. Why not?

I think the days of using placement agents are, well, I guess, no comment. I suppose they might be useful if you’re trying to raise a lot of money and you don’t have enough hours in the day and you need someone to help facilitate relationships. But I think LPs would just assume not have placement agents because it just adds another layer of worry after the various problems that have happened in the past.

When you raise a new fund, how probing are investors as far as their due diligence?

The level of due diligence certainly hasn’t gone down. But GPs have gotten a lot better at it. GPs have to be prepared. Years ago, when we were raising our second or third fund, we almost waited until our LPs asked us for information, and then we would prepare it. Nowadays, before we mail out our first memorandum, our data room is populated with every conceivable question somebody could ask. If you do these things in advance, it can literally save you months of time. You have no idea the amount of information we have to provide people. Part of what LPs are doing is checking on the integrity of the GPs. There is also quite a bit of studying portfolio companies to see how we made our money.

Besides returns, what do your investors want most?

LPs really don’t like surprises. When you present a new fund, you would like to say that nothing has changed: same partners, same strategy, same solid performance. They would rather have you make your money from 10 good investments rather than one great investment. What they want is as much predictability, stability and certainty as possible. They’ve got a lot of money to look over, and what they don’t like is problems. They’re not in the work-out business.

“Thoma Bravo is eager to work with existing management of InfoVista to position the company for further growth and strengthened global leadership in the service performance assurance industry,” said Thoma Bravo principal Robert Sayle. “As a strategic partner, we are confident our approach and experience in identifying strategic and organic opportunities will establish a platform for the company’s continued success.”

“We are exited to partner with Thoma Bravo to propel the company forward as a leader in the service performance assurance industry,” said Philippe Ozanian, chief executive officer of InfoVista. “Our customers will continue to receive the same experience they’ve grown accustomed to and can expect a renewed focus to enhance our suite of solutions now as a private company.”

* Dell not to take additional debt for buyout

* Says deal to close by July 2012

March 13 (Reuters) – Dell Inc said it would buy network security products maker SonicWall from an investor group as the world’s No. 3 personal computer maker tries to tap growing demand to protect corporate networks.

Dell is trying to boost profit margins by focusing on being a one-stop shop for business customers by adding products in areas including security, storage and cloud computing so it can rely less on the PC business for which it is best known.

“There’s an opportunity to have higher growth margins and higher operating margins,” FBN Securities analyst Shebly Seyrafi said.

This is the first deal for Dell after John Swainson took over as its software chief last week with a mandate to expand its software capabilities. Swainson said it had been in the works long before he had been hired.

Though financial terms were not disclosed, investors and analysts are estimating the purchase price to be between $1 billion and $1.5 billion.

On a conference call with analysts, Dell said it will fund the deal with cash but declined to divulge the purchase price.

SonicWall was a public company until 2010, when it was acquired by an investor group led by Thoma Bravo for $717 million.

The firm is best known for selling Unified Threat Management technologies that small and mid-sized businesses use to protect their networks from computer viruses, spam and other cyber threats.

It has recently expanded into selling more robust corporate security products known as next-generation firewalls with lots of bells and whistles that big corporations can use to monitor their workers and protect them from attack when they are using specific online applications like Facebook.

“It’s a big market opportunity for anybody to get into. When you have the clout of Dell, it does make sense,” said Andrew Hay, an analyst with The 451 Group.

Analysts said they expect Dell to build out SonicWall’s line of products, then market them to bigger corporations and sell its alongside other products to data centers and large enterprises.

“This basically is part of the whole game plan that they have put in place, that is to acquire a key technology. They’ve been doing this in enterprise storage, in networking, and now they’re doing this in security as well,” said analyst Brian Marshall of ISI Group.

Round Rock, Texas-based Dell has been waging an uphill battle to diversify its revenue base from PCs to become a larger player in the data center equipment market and IT services. It faces stiff competition in those markets from the likes of IBM and HP.

To help that effort, it has been acquiring companies, including Force 10 Networks and Compellent Technologies, to boost its enterprise-related products and services.

Last year, Dell made a splash in the security industry by purchasing SecureWorks, which remotely monitors corporate networks to help companies identify when they have been attacked. The price was not disclosed.

Swainson said in a press call that the company would look at other acquisitions to help it expand further in security, where rivals like IBM and HP have also used deals to boost their market position.

“Our customers have consistently presented us with concerns about their security,” Swainson said.

Founded in 1991, San Jose, California-based SonicWall had revenue of $260 million last year and boasts of 300,000 customers.

“SonicWall is going to contribute less than 1 percent to Dell’s revenue, but they’re moving in the right direction,” analyst Marshall said.

The deal is expected to close within 45 days.

Centerview Partners LLC served as an adviser to SonicWall. Dewey & LeBoeuf advised Dell.

Dell shares rose 15 cents to $17.11 in afternoon trade on Tuesday on the Nasdaq.

“We are proud of our strong partnership with the SonicWALL management team,” said Thoma Bravo managing partner Orlando Bravo. “During our ownership of the company, their implementation of our operational strategies resulted in a significant increase in SonicWALL’s value.”

“We are pleased to have worked with SonicWALL during this period of increased growth and investment.  The company’s ability to achieve and sustain leadership and innovation in advanced IT security for customers of all sizes helped attract this acquisition by Dell, a leading global innovator in technology,” added Seth Boro, partner at Thoma Bravo.

Thoma Bravo led an investor group that includes Ontario Teachers’ Pension Plan (through its private equity group, Teachers’ Private Capital) in the acquisition of SonicWALL, formerly a public company, in a take-private transaction in 2010.

“We appreciate the expertise Thoma Bravo brought to SonicWALL and attribute our recent growth and strengthened position in the network security industry to the leadership and operational best practices that Thoma Bravo brought to our partnership,” said SonicWALL President and CEO Matt Medeiros. “We remain committed to providing dynamic solutions and exceptional customer support to enterprise organizations worldwide and look forward to this next phase of growth with Dell.”

Established in 1991 and headquartered in San Jose, CA, SonicWALL provides dynamic network security and data protection solutions for small, mid-sized and large enterprise organizations worldwide. With offices in 23 countries and more than 950 employees serving customers in 50 countries, SonicWALL delivers award-winning solutions that include network security, secure remote access, email security, backup and recovery, and policy and management.

Centerview Partners LLC served as an advisor to SonicWALL.

The transaction is expected to close within 45 days.
