DATALINK REPORTS 2011 THIRD QUARTER AND NINE MONTH OPERATING RESULTS

Record Third Quarter and Nine Month Revenues Up 30% and 31% Year-Over-Year, Respectively

CHANHASSEN, Minn., October 19, 2011 — Datalink (Nasdaq: DTLK), a leading provider of data center infrastructure and services, today reported results for its third quarter and nine month period that ended September 30, 2011.  Revenues for the quarter ended September 30, 2011, increased 30% to $90.1 million compared to $69.2 million for the prior-year period.  Revenues for nine months ended September 30, 2011, increased 31% to $265.3 million compared to $202.6 million for the nine months ended September 30, 2010.

GAAP Results

On a GAAP basis, the company reported net earnings of $2.8 million or $0.16 per diluted share for the third quarter ended September 30, 2011.  This compares to net earnings of $771,000 or $0.06 per diluted share in the third quarter of 2010.  For the nine months ended September 30, 2011, the company reported net earnings of $7.2 million, or $0.45 per diluted share, compared to a net loss of $115,000, or $0.01 per diluted share, for the nine months ended September 30, 2010.

Non-GAAP Results

Non-GAAP net earnings for the third quarter of 2011 were $3.5 million, or $0.21 per diluted share, compared to non-GAAP net earnings of $1.4 million or $0.11 per diluted share, in the third quarter of 2010.  For the nine months ended September 30, 2011, the company reported non-GAAP net earnings of $8.9 million, or $0.56 per diluted share, compared to net earnings of $2.2 million, or $0.17 per diluted share, for the nine months ended September 30, 2010.  A detailed reconciliation between GAAP and non-GAAP information is contained in the tables included herein.

Paul Lidsky, Datalink President and CEO, commented, “Both revenue and earnings for the third quarter and first nine months of 2011 were records for Datalink.  In addition, this represents our tenth consecutive quarter of non-GAAP net earnings.  Our momentum from a record first half of 2011 has continued and our pipeline, and order flow in the first few weeks of the quarter indicate that this momentum should continue through the fourth quarter.”

Significant accomplishments for the third quarter of 2011 include:

·      Continued growth in multi-million dollar accounts among Global 1000 companies. In the first nine months of 2011, we had 52 customers purchase over $1 million of product and services from Datalink as compared to 37 customers in the first nine months of 2010.  In addition, the company acquired 69 new customers in the third quarter of 2011.

·      Validating Datalink’s commitment to customer intimacy as a cornerstone of its go-to-market strategy to deliver premier services to our customers, the company experienced a 14% increase in services to a record $34.5 million in the third quarter.

·      On October 3, 2011 Datalink acquired the assets of Midwave Corporation, doubling the company’s footprint in the Twin Cities and making it the dominant data center services and infrastructure provider in the region.  The acquisition also doubles Datalink’s Cisco technology and services revenues, expands its managed services portfolio with the addition of a data center infrastructure monitoring service, adds an established security practice including product, services and consulting, and doubles the size of its consulting services team.

·      Datalink exited the quarter with a strong balance sheet.  The company’s working capital increased $5.5 million to $51.6 million, with no debt outstanding.  After the Midwave acquisition the company will still have working capital in excess of $35 million, cash and investments of approximately $20 million and no debt.

Outlook

Based on the company’s backlog, sales pipeline, and the results from the acquisition of Midwave, we expect revenues to be between $110 million and $115 million for the fourth quarter of 2011.  This compares to revenues of $91.1 million in the fourth quarter of 2010.  Fourth quarter 2011 net earnings are anticipated to be between $0.17 and $0.22 per diluted share on a GAAP basis, and net earnings to be between $0.22 and $0.27 per diluted share on a non-GAAP basis.  This guidance includes an expected $15 million of revenues from the Midwave acquisition in the fourth quarter.

Non-GAAP earnings per share exclude the effect of acquisition accounting adjustments from the Incentra acquisition to deferred revenue and costs, integration and transaction costs related to acquisitions, stock-based compensation expense, amortization of intangible assets, and the related effects on income taxes. The company estimates this total effect will be approximately $0.05 per diluted share for the fourth quarter of 2011.

Effect of Accounting Change

Effective January 1, 2011, the company was required to adopt a new revenue recognition accounting standard.  This new standard, which applies to all resellers of computer hardware, requires that the company now recognize product revenues upon shipment versus upon installation under its old revenue recognition method.  Accordingly the company’s third quarter and nine months of 2011 results reflects this new revenue recognition policy.  The company’s revenue for the first nine months of 2011 includes $8.6 million of revenues that were recognized in the first nine months of 2011 that would have been recognized in the fourth quarter of 2010 if the company had been recognizing revenue upon shipment in 2010.

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for certain forward-looking statements.  This press release contains forward-looking statements, including our internal projections of anticipated 2011 results, which reflect our views regarding future events and financial performance.  These forward-looking statements are subject to certain risks and uncertainties, including those identified below, which could cause actual results to differ materially from historical results or those anticipated.  The words “aim, “believe,” “expect,” “anticipate,” “intend,” “estimate”, “should” and other expressions which indicate future events and trends identify forward-looking statements.  Actual future results and trends may differ materially from historical results or those anticipated depending upon a variety of factors, including, but not limited to:  the level of continuing demand for storage, including the effects of current economic and credit conditions; 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; revenue recognition policies that may unpredictably defer reporting of our revenues; our ability to hire and retain key technical and sales personnel; our dependence on key suppliers; our ability to adapt to rapid technological change; risks associated with integrating our acquisition of Midwave Corporation or any possible future acquisitions; fluctuations in our quarterly operating results; future changes in applicable accounting rules; and volatility in our stock price. Further, our revenues for any particular quarter are not necessarily reflected by our backlog of contracted orders, which also may fluctuate unpredictably.  We cannot assure that we can grow or maintain our revenue and backlog from current levels.

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 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.
