Infoblox Reports Second Quarter of Fiscal 2015 Results

Company Reports Record Revenue

SANTA CLARA, Calif., February 26, 2015 — Infoblox (NYSE:BLOX), the network control company, today reported its financial results for its second fiscal quarter ended January 31, 2015. Total net revenue for the second quarter of fiscal 2015 was a record $74.3 million, an increase of 22.0% on a year-over-year basis.

On a GAAP basis, the Company reported a net loss of $7.0 million, or $0.13 net loss per fully diluted share, for the second quarter of fiscal 2015, compared with a net loss of $4.4 million, or $0.08 net loss per fully diluted share, for the second quarter of fiscal 2014.

The Company reported non-GAAP net income of $5.3 million, or $0.09 diluted net income per share on a non-GAAP weighted-average share basis, for the second quarter of fiscal 2015, compared with non-GAAP net income of $6.6 million, or $0.11 diluted net income per share on a non-GAAP weighted-average share basis, for the second quarter of fiscal 2014. The GAAP to non-GAAP reconciling items for the second quarters of fiscal years 2015 and 2014 can be found in the "Reconciliation of GAAP to Non-GAAP Financial Measures" attached to this press release.

“We are very pleased with our second quarter financial results and our ability to deliver strong product revenue growth,” said Jesper Andersen, president and chief executive officer of Infoblox. “In the quarter, strengthening demand for our DDI, security and cloud solutions drove both year-over-year and sequential revenue growth in all three geographic regions. We also experienced a strong quarter from a new customer acquisition standpoint and added approximately 250 customers. As we look forward, we believe the company is well positioned to build on the momentum that was generated in the first two quarters of the fiscal year.”

Financial Outlook

Infoblox announced its outlook of anticipated results for the third quarter ending April 30, 2015. This outlook is based on a number of assumptions that it believes are reasonable at the time of this earnings release. Information regarding potential risks that could cause the actual results to differ from these forward-looking statements is set forth below and in Infoblox’s filings with the Securities and Exchange Commission.

For the third fiscal quarter ending April 30, 2015, the Company currently expects:

•Total net revenue in the range of $74 million to $76 million;

•Non-GAAP gross margin to be in the range of 78% to 79%;

•Non-GAAP operating margin in the range of 5.5% to 6.5%; and

•Non-GAAP diluted net income per share ("non-GAAP EPS") to be in the range of $0.06 to $0.08, assuming approximately 60 million shares on a non-GAAP diluted weighted-average share basis.

About Non-GAAP Financial Measures

To supplement our financial results presented in accordance with Generally Accepted Accounting Principles (GAAP), this press release and the accompanying tables and the related earnings conference call contain certain non-GAAP financial measures, including non-GAAP gross profit and gross margin, non-GAAP operating income and operating margin, non-GAAP net income, non-GAAP EPS and non-GAAP diluted weighted-average shares outstanding. We also provide third fiscal quarter 2015 estimates for non-GAAP gross margin, non-GAAP operating margin, non-GAAP EPS and non-GAAP diluted weighted-average shares outstanding. We believe these non-GAAP financial measures are helpful in understanding our past financial performance and future results. Our non-GAAP financial measures should not be considered in isolation or as a substitute for comparable GAAP measures and should be read in conjunction with our consolidated financial statements prepared in accordance with GAAP. Our management regularly uses our supplemental non-GAAP financial measures internally to understand and manage our business and forecast future periods. These non-GAAP financial measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similar measures presented by other companies. Our non-GAAP financial measures include adjustments based on the following items:

Stock-based compensation expenses: We have excluded the effect of stock-based compensation from our non-GAAP operating results. Although stock-based compensation is a key incentive offered to our employees, we continue to evaluate our business performance excluding stock-based compensation expenses. Stock-based compensation expenses will recur in future periods.

Amortization of intangible assets: We have excluded the effect of amortization of intangible assets from our non-GAAP operating results. Amortization of intangible assets is a non-cash expense, and it is not part of our core operations. Investors should note that the use of intangible assets contributed to revenues earned during the periods presented and will contribute to future period revenues as well.

Income tax adjustment: For purposes of calculating non-GAAP net income and non-GAAP EPS, our interim U.S. income tax provision is recognized based on the percentage of year-to-date non-GAAP pre-tax income (loss) over projected fiscal 2015 non-GAAP pre-tax income (loss).

Acquisition related expenses: Acquisition related expenses may include transaction costs, costs for transitional employees, other acquired employee related retention costs, integration related professional services, adjustments to the fair value of the acquisition related contingent consideration, and the write-down of certain acquired in-progress research and development intangibles. We believe that to the extent we incur significant expenses in connection with our acquisitions, it is useful for investors to understand the effects of these items on our total operating expenses.

Our non-GAAP Financial Measures are described as follows:

Non-GAAP gross profit and gross margin. Non-GAAP gross profit is gross profit as reported on our consolidated statements of operations, excluding the impact of stock-based compensation and intangible asset amortization expense. Non-GAAP gross margin is non-GAAP gross profit divided by net revenue.

Non-GAAP operating income and operating margin. Non-GAAP operating income is income (loss) from operations as reported on our consolidated statements of operations, excluding the impact of stock-based compensation, intangible asset amortization expense and acquisition related expenses. Non-GAAP operating margin is non-GAAP operating income divided by net revenue.

Non-GAAP net income and non-GAAP EPS. Non-GAAP net income is net income (loss) as reported on our consolidated statements of operations, excluding the impact of stock-based compensation, intangible asset amortization expense and acquisition related expenses with income taxes adjusted to reflect our estimated effective tax rate on a non-GAAP basis. Non-GAAP EPS is non-GAAP net income divided by non-GAAP diluted weighted-average shares outstanding.

For reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures, please see the section of the accompanying tables titled, “Reconciliation of GAAP to Non-GAAP Financial Measures.”
