DATALINK REPORTS 2011 FOURTH QUARTER AND YEAR-END OPERATING RESULTS

Record Fourth Quarter and Annual Revenue Up 26% and 29% Year-Over-Year, Respectively

CHANHASSEN, Minn., February 16, 2012 — Datalink (Nasdaq: DTLK), a leading provider of data center infrastructure and services, today reported results for its fourth quarter and year that ended December 31, 2011.  Revenues for the quarter ended December 31, 2011, increased 26% to $114.7 million compared to $91.0 million for the prior-year period.  Revenues for year ended December 31, 2011, increased 29% to $380.0 million compared to $293.7 million for the year ended December 31, 2010.

GAAP Results

On a GAAP basis, the company reported net earnings of $2.6 million or $0.15 per diluted share for the fourth quarter ended December 31, 2011.  This compares to net earnings of $2.4 million or $0.19 per diluted share in the fourth quarter of 2010. For the year ended December 31, 2011, the company reported net earnings of $9.8 million or $0.61 per diluted share, compared to net earnings of $2.3 million, or $0.18 per basic and diluted share, for the year ended December 31, 2010.

Non-GAAP Results

Non-GAAP net earnings for the fourth quarter of 2011 were $4.1 million, or $0.24 per diluted share, compared to non-GAAP net earnings of $3.1 million, or $0.24 per diluted share, in the fourth quarter of 2010.  For the year ended December 31, 2011, the company reported non-GAAP net earnings of $13.0 million, or $0.80 per diluted share, compared to net earnings of $5.4 million, or $0.41 per diluted share, for the year ended December 31, 2010.  A detailed

reconciliation between GAAP and non-GAAP information is contained in the tables included herein.

The company’s results for the quarter and year ended December 31, 2011 include:

·                  The additional 3.3 million common shares issued in connection with the follow-on stock offering in March 2011.  The dilution on GAAP and non-GAAP earnings from the additional shares outstanding on the 2011 fourth quarter and full year’s earnings was approximately $0.05 per share and $0.16 per share, respectively.

·                  The results of operations from the acquisition of Midwave Corporation, which was completed on October 3, 2011. Excluding Midwave, revenues for the fourth quarter and year ended December 31, 2011, would have increased approximately 12% and 25%, respectively compared to the prior year periods.  The acquisition had no impact on GAAP or non-GAAP earnings in the fourth quarter of 2011.

·                  For the fourth quarter GAAP results, the benefit of the receipt of a $553,000, or approximately $0.02 per share early termination payment relating to the earn-out under the October 2009 purchase agreement with Cross Telecom.  Under the terms of the purchase agreement, Cross was required to expend $600,000 with Datalink for goods and services for the period October 2011 through September 2012.  Cross elected to terminate the commitment with a lump sum buy-out payment in October 2011. The benefit from this payment is not included in Non-GAAP earnings for the fourth quarter of 2011.

Paul Lidsky, Datalink’s president and CEO, commented, “2011 was a record year for Datalink.  We reported revenues of $380 million and our highest earnings ever.  In addition, the $114.7 million of revenues in the fourth quarter of 2011 is a quarterly record for Datalink.  We also reported our eleventh consecutive quarter of non-GAAP net earnings.”

Other significant accomplishments for 2011 and the fourth quarter include:

·                  A record $77.9 million in product revenues for the quarter, which represents a 40% increase over third quarter and a 32% increase over the same period in 2010.  In addition, service revenues were a record $36.8 million in the fourth quarter. These increases reflect both the acquisition of Midwave Corporation and Datalink’s ability to continue to close multi-million dollar accounts during the fourth quarter.

·                  Continued growth in multi-million dollar accounts among Global 1000 companies. In 2011, the company saw 77 customers purchase over $1 million of product and services from Datalink as compared to 55 customers in 2010.  In addition, the company acquired 290 new customers in 2011 as compared to 272 in 2010.

·                  A follow on offering 3.3 million shares that closed in March 2011, generating approximately $17 million of cash to be primarily used for acquisitions.  On October 3, 2011, the company used these funds to acquire the assets of Midwave Corporation, doubling its footprint in the Twin Cities and making Datalink the dominant data center services and infrastructure provider in the region.  The acquisition also doubled the company’s Cisco technology and services revenues, expanded its managed services portfolio with the addition of a data center infrastructure monitoring service, added an established security practice including product, services and consulting, and doubled the size of Datalink’s consulting services team.  While the acquisition was only slightly accretive in its first quarter of operations and as expected did not generate enough earnings to offset the dilution from the follow-on offering, the company expects the acquisition to have a positive earnings impact once all of the synergies are recognized by the second half of 2012.

·                  Achievement of the industry’s first NetApp Specialization in “Data Center - FlexPod” Unified Architectures certification.  The new specialization recognizes Datalink as having fulfilled one of the most rigorous levels of solution competency recognized by NetApp and includes NetApp, Cisco and VMware top certification requirements.

·                  Significant momentum for the company’s virtualized data center (VDC) solutions, with 22 solution projects sold in Q4 compared to 6 in the comparable period in 2010, and 89 deals for the whole year compared to 33 in 2010.

·                  Exiting the quarter with a healthy and strong balance sheet with working capital of $37.9 million, cash and investments of $22.4 million, and continued debt-free status.

“Datalink’s collective accomplishments during 2011 reaffirm our successful execution on our acquisition and data center strategies.  These strategies, coupled with improving economic conditions, resulted in increased revenue and gross margin dollars throughout the year,” Lidsky said.  “This allowed us to leverage our fixed expenses culminating in a 2011 non-GAAP operating profit margin of 5.8% and 2011 non-GAAP operating earnings of $21.9 million as compared to a 2010 non-GAAP operating profit margin of 3.3% and 2010 non-GAAP operating income of $9.6 million.

“In addition, our strong 2011 performance left us with a record backlog going into the first quarter and accelerated activity that has carried over with strong sales in the first months of Q1,” Lidsky added. “As we exit the year, we continue to see increasing demand for unified data center solutions with flexible architectures. Our investments in our expanded data center portfolio support these market conditions, and our ability to deliver unified platforms to our customers should fuel growth in 2012.”

Outlook

With the strong start to the new year, Datalink’s first quarter guidance suggests a 17% to 24% year-over-year revenue increase in fiscal 2012.  Based on the company’s current backlog and sales pipeline, the company projects revenues of $108 million to $116 million for Q1 2012 compared to $85.7 million for Q1 2011. In addition, Datalink’s first quarter operating expenses are typically higher than other quarters. Therefore the company expects first quarter 2012 net earnings to be between $0.07 and $0.12 per diluted share on a GAAP basis, and net earnings of between $0.13 and $0.18 per diluted share on a non-GAAP basis.  This compares to net earnings of $0.12 per diluted share and $0.16 per diluted share on a GAAP and non-GAAP basis, respectively, for the same period in 2011.

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 $0.06 per diluted share for the first quarter of 2012.

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 fourth quarter and twelve months of 2011 results reflects this new revenue recognition policy.  The company’s revenue for 2011 includes $8.6 million of revenues that would have been recognized in the fourth quarter of 2010 if the company had been recognizing revenue upon shipment in 2010.   These revenues were recognized in the first and second quarters of 2011.

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, early termination payments related to the Cross acquisition 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.
