CDW Provides Business Updates on Impact ofCOVID-19

LINCOLNSHIRE, Ill., April 16, 2020 (GLOBE NEWSWIRE) — CDW Corporation (Nasdaq:CDW) today announced updates related to the novel coronavirus,COVID-19.    

“Our mission at CDW is to help our customers navigate change and be successful in an ever-evolving world. This mission is even more relevant during the currentCOVID-19 crisis,” said Christine A. Leahy, chief executive officer, CDW. “First quarter demand was strong as customers looked to CDW to meet urgent needs for greater technology capabilities. CDW teams have worked tirelessly to safeguard the health and well-being of each other and to continue delivering for our customers at this time of great need.”

“Given the depth and duration of the pandemic is unknown, it is too early to predict the full impact ofCOVID-19 on our business. We are committed to deliver on our mission by providing the essential technology required across all sectors of the economy – from vital healthcare, education and government entities to businesses of all sizes – as organizations strive to achieve their goals during this pandemic,” concluded Leahy.

Business Update

For the first quarter, preliminary Net sales are expected to be $4.39 billion, Operating income is expected to be $246 million andNon-GAAP operating income is expected to be $304 million. Net income per diluted share is expected to be $1.16 andNon-GAAP net income per diluted share is expected to be $1.38.Non-GAAP operating income andNon-GAAP net income per diluted share are measures that are not based on accounting principles generally accepted in the United States (“GAAP”). Reconciliations to the most directly comparable GAAP measures are included in the attached schedules. These preliminary results have not been reviewed, audited or subjected to any agreed-upon procedures by our independent registered public accounting firm. Final results for the first quarter may ultimately differ from these preliminary results.

CDW is focused on the well-being and safety of its coworkers, leveraging standing crisis management protocols and following guidelines from public health authorities. CDW implemented precautions to help keep its coworkers healthy and safe, including activating a cross-functional response team led by Executive Committee members, moving to remote working for its office coworkers, and implementing safety protocols at its distribution centers, including social distancing measures, segmented shifts, additional personal protective equipment, enhanced facility cleanings, and temperature screening for anyone entering the facilities. In recent weeks, to limit the virus spread after a few coworkers tested positive forCOVID-19, CDW decided to close its Vernon Hills, Illinois distribution center for several days and to require a shift of configuration center coworkers to self-isolate. CDW has continued to pay its affected coworkers their wages. These actions have not had a material impact to date as the company leveraged flexibility in its distribution and configuration capabilities where possible, and where not, shipping times modestly increased.

2020 Targets and Related 2020 Financial Information

As a result ofCOVID-19 and the adoption of current and potential future measures to prevent its spread, CDW is withdrawing its 2020 targets and related 2020 financial information that were previously issued on February 6, 2020. While CDW has a balanced portfolio of customerend-markets and a full suite of solutions and services that address customer priorities across the IT landscape, the impact ofCOVID-19 on CDW’s businesses could be material with some customerend-markets impacted more significantly than others or due to operational measures taken to safeguard its coworkers or issues with its supply chain. CDW is unable at this time to predict the impact ofCOVID-19 on its operations, liquidity, and financial results, and, depending on the magnitude and duration of theCOVID-19 pandemic, such impact may be material.

Liquidity

The company remains confident in its liquidity position. CDW’s primary liquidity sources are operating cash flow, cash and cash equivalents, and borrowings under its revolving credit facilities. As of March 31, 2020, CDW had cash and cash equivalents of $214 million and $3.47 billion of total debt outstanding, plus the capacity to borrow an additional $1.0 billion under its revolving credit facilities. The company has no debt maturities due in 2020 and $57 million (£46 million) of debt maturing in August 2021. The company has taken measures to enhance liquidity, including implementing cost savings initiatives and suspending share repurchases.

The company will provide an update in its first quarter earnings release and on its first quarter earnings call.
