DATALINK REPORTS 2014 FIRST QUARTER OPERATING RESULTS

First-Quarter Revenues Up 5% Year-Over-Year, Including 15% Increase in Services

EDEN PRAIRIE, Minn., May 6, 2014 — Datalink (Nasdaq: DTLK), a leading provider of data center infrastructure and services, today reported results for its first quarter ended March 31, 2014.  Revenues for the quarter ended March 31, 2014, increased 5% to $139.5 million compared to $133.5 million for the quarter ended March 31, 2013.   Product revenues decreased 1% to $83.2 million and services revenues increased 15% to $56.3 million year over year.

The company’s results for the quarter ended March 31, 2014, reflect the full impact of the additional 3.8 million common shares issued in connection with the follow-on stock offering which closed on August 14, 2013.  The dilution on GAAP and non-GAAP earnings from the additional shares outstanding on the 2014 first quarter was approximately $0.01 per share.

The first quarter of 2014 GAAP results also includes an $876,000 or $0.02 per share gain relating to the escrow settlement agreement reached with StraTech in January 2014.  Under the terms of the agreement, related to Datalink’s acquisition of StraTech in October 2012, the former owners of StraTech agreed to release the entire 242,805 shares of Datalink common stock that were being held in escrow in exchange for a payment of $100,000 and the release of certain other claims.  The gain is based on the value of Datalink common stock on the date of the agreement. In the fourth quarter of 2013 we recorded a write-down of $611,000 of the account receivable from StraTech to its estimated realizable value.  The net impact on our financial statements between the fourth quarter of 2013 and the first quarter of 2014 is a net gain of $265,000.

GAAP Results

On a GAAP basis, the company reported net earnings of $301,000 or $0.01 per diluted share for the first quarter ended March 31, 2014.  This compares to net earnings of $1.1 million or $0.06 per diluted share in the first quarter of 2013.

Non-GAAP Results

Non-GAAP net earnings for the first quarter of 2014 were $1.2 million, or $0.06 per diluted share, compared to $3.1 million, or $0.18 per diluted share, in the first quarter of 2013. A detailed reconciliation between GAAP and non-GAAP information is contained in the tables included herein.

“These first quarter results produced top line growth greater than most of our OEM partners are experiencing but were less than the revenue and earnings guidance we gave in February and reflect a greater decline in our overall gross margin than we expected. This decline in gross margin was caused by storage orders forecasted to close during Q1 that were delayed because customers were still evaluating their hybrid cloud and solid state storage strategies,” said Paul Lidsky, president and CEO of Datalink.  “Since these delays primarily affected storage decisions, a higher percentage of our revenues came from lower-margin server and networking purchases, which in turn produced lower overall gross margins.  While we believe that we will see these orders materialize later in the year and our storage/server and networking mix will return to expected levels, we have taken multiple cost reduction and organizational actions to protect our earnings and help the company increase its top line growth.”

These actions - effective immediately- will reduce operating expenses by approximately $3.6 million for the remainder of the year or $0.10 per fully diluted share.  They include a restructuring of the sales operations and services delivery organizations which will provide greater efficiency while driving increased growth. In the second quarter, the company will take a one-time charge of approximately $350,000 relating to severance payments from these actions.

The company is also continuing to focus on driving higher-margin services revenues.  That focus yielded a strong Q1 services performance, including:

·                  A 15% year-over-year increase in total services revenues, including a 28% increase in professional services revenues.

·                  An increase in professional services to 8.1% of total revenues compared to 6.6% in the first quarter of 2013.

·                  Major new engagements in the company’s recently expanded Advanced Services practice, ranging from data center relocations, infrastructure migrations and hybrid cloud orchestration and management to a $1.9 million data migration contract with a large banking institution.

“In the past few years we have steadily broadened our services portfolio to provide a higher-margin revenue stream as well as to help our customers address the growing complexity of the data center infrastructure in the face of new developments like converged architectures, cloud computing and the transition of IT teams to become service organizations. These numbers show that the strategy is succeeding even in a down quarter,” Lidsky said. “Services will play an increasingly important role in our growth moving forward, continue to increase our wallet share with customers, and provide a strong competitive advantage over providers that lack our full-service capabilities.”

During the first quarter, Datalink continued to maintain a strong balance sheet with cash and investments of over $71 million, no debt and working capital of $93 million.

Outlook

Datalink projects revenues of $145 million to $155 million for the second quarter of 2014 compared to $148.2 million for the second quarter of 2013.  The company expects second quarter 2014 net earnings to be between $0.04 and $0.09 per diluted share on a GAAP basis, and net earnings of between $0.11 and $0.16 per diluted share on a non-GAAP basis.  This compares

to net earnings of $0.16 per diluted share and $0.26 per diluted share on a GAAP and non-GAAP basis, respectively, for the same period in 2013.

Non-GAAP earnings per share exclude the effect of acquisition accounting adjustments from the StraTech asset acquisition to deferred revenue and costs, integration and transaction costs related to acquisitions, stock-based compensation expense, amortization of intangible assets, severance costs, and the related effects on income taxes. The company estimates this total effect will be approximately $0.07 per diluted share for the second quarter of 2014.

The words “aim,” “believe,” “expect,” “anticipate,” “intend,” “estimate,” “should” and other expressions which indicate future

Actual future results and trends may differ materially from historical results or those anticipated depending upon a variety of factors, many of which are included under “Risk Factors” in our annual report on Form 10-K for our year ended December 31, 2013, including, but not limited to: the level of continuing demand for data center solutions and services including the effects of current economic and credit conditions and the ability of organizations to outsource data center infrastructure-related services to service providers such as us; the migration of organizations to virtualized server environments, including using a private cloud computing infrastructure; the extent to which customers deploy disk-based backup recovery solutions; the realization of the expected trends identified for advanced network infrastructures; reliance by manufacturers on their data service partners to integrate their specialized products; continued preferred status with certain principal suppliers; competition and pricing pressures and timing of our installations that may adversely affect our revenues and profits; fixed employment costs that may impact profitability if we suffer revenue shortfalls; our ability to hire and retain key technical and sales personnel; continued productivity of our sales personnel; our dependence on key suppliers; our ability to adapt to rapid technological change; success of the implementation of our enterprise resource planning system; risks associated with integrating completed and future acquisitions; the ability to execute our acquisition strategy; fluctuations in our quarterly operating results; future changes in applicable accounting rules; and volatility in our stock price.

Non-GAAP Details

Non-GAAP financial measures exclude the impact from acquisition accounting adjustments to deferred revenue and costs, stock-based compensation expense, amortization of acquisition intangible assets, integration and transaction costs related to acquisitions, severance costs and the related effects on income taxes.  These non-GAAP measures are not in accordance with, or an alternative for measures prepared in accordance with, GAAP and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. We believe that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with our results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures.

These non-GAAP financial measures facilitate management’s internal comparisons to our historical operating results and comparisons to competitors’ operating results. We include these

non-GAAP financial measures in our earnings announcement because we believe they are useful to investors in allowing for greater transparency with respect to supplemental information used by management in its financial and operational decision making, such as employee compensation planning. We believe that the presentation of these non-GAAP measures when shown in conjunction with the corresponding GAAP measures provides useful information to investors and management regarding financial and business trends relating to our financial condition and results of operations.
