Vocera Reports Second Quarter 2013 Results

SAN JOSE, Calif., August 5, 2013 -Vocera Communications, Inc. (NYSE: VCRA), the leading provider of solutions that address critical communication and productivity challenges facing healthcare, hospitality, retail and other mobile work environments, today announced unaudited results for its second quarter ended June 30, 2013.

Revenue for the second quarter of 2013 was $25.3 million, an increase of 12.9% sequentially and 1.7% compared to $24.9 million in the second quarter of 2012. For the second quarter of 2013, GAAP net loss was $2.0 million, or $0.08 per diluted share, compared to a net income of $1.2 million in the second quarter of 2012. Non-GAAP net income was $175,000 for the second quarter of 2013, or $0.01 per diluted share, compared to non-GAAP net income of $2.3 million or $0.09 per diluted share, for the second quarter of 2012. A reconciliation of GAAP to non-GAAP financial measures is provided in the schedules included below.

“We had a solid second quarter, including strong bookings growth in our core U.S. healthcare market, the signing of a large new Veterans hospital contract, as well as the shipment of a record number of Vocera badges. These accomplishments are encouraging, and yet we still believe the hospital spending environment remains tight. In spite of these challenges, over the last two quarters we have experienced strong bookings in new facilities and subscription based solutions. While these bookings have strengthened our backlog, they are taking longer to convert to revenue.” commented Brent Lang, Vocera President and Chief Executive Officer.

Second Quarter 2013 Results

2013 Guidance

For the full year 2013, we are narrowing our revenue guidance to a range of $102 million to $105 million. We expect GAAP earnings per share to be between a loss of $0.44 and $0.34, non-GAAP earnings per share to be between a loss of $0.04 and a profit of $0.03, and non-GAAP Adjusted EBITDA to be between $900,000 and $2.8 million. Our full year 2013 non-GAAP guidance excludes estimated stock-based compensation expense of $9.0 million to $9.5 million and estimated amortization of intangibles of approximately $0.7 million. Non-GAAP earnings per share guidance is based on a fully diluted share count for the full year 2013 of 24.8 million shares in the event of a loss and 27.2 million shares in the event of a profit, and expected income tax of $0.2 million to $0.4 million.

For the third quarter of 2013, we expect revenues to be between $25.5 million and $26.5 million, GAAP loss per share between $0.16 and $0.10, non-GAAP earnings between a loss of $700,000 and breakeven, non-GAAP earnings per share between a loss of $0.03 and $0.00, and non-GAAP Adjusted EBITDA between a loss of $200,000 and a gain of $500,000. Our third quarter 2013 non-GAAP guidance excludes stock-based compensation expense of approximately $2.6 million and amortization of intangibles of $0.2 million. Non-GAAP earnings per share guidance is based on a fully diluted share count of 24.9 million shares in the case of a loss and 27.5 million shares in the case of a gain, for the third quarter 2013. Income tax for the third quarter of 2013 is expected to be approximately $100,000.

Forward Looking Statements

Statements in this press release that are not strictly historical in nature are forward-looking statements within the meaning of the U.S. federal securities laws, including statements regarding future events, such as our expected operating results for the full year and third quarter of 2013, the future financial performance of our company and the effect macro economic conditions affecting the health care industry will have on our business and results of operations. These forward-looking statements are based on limited information currently available to us and our management’s expectations, which are inherently subject to change and involve a number of risks and uncertainties. Actual events or results may differ materially from those in any forward-looking statement due to various factors, including but not limited to the effects of recently enacted U.S. healthcare reform, the effects on government hospital customers of the sequester and budgetary uncertainty, our ability to maintain profitability; the demand for our Voice Communication solution in the healthcare market; our lengthy and unpredictable sales cycle; our ability to offer high-quality services and support for our solutions, to acquire the sole and limited source hardware and software components of our solutions, to obtain the required capacity and product quality from our contract manufacturer, to develop and introduce new solutions and features to existing solutions and to manage our growth; and the other factors described in our Annual Report on Form 10-K for 2012, Quarterly Report on Form 10-Q for the first quarter of 2013 and our other filings

with the SEC. Our filings with the Securities and Exchange Commission (“SEC”) are available on the Investors section of our company’s web site at www.vocera.com. The financial and other information contained in this press release should be read in conjunction with the financial statements and notes thereto included in our filings with the SEC. Our operating results for the second quarter of 2013 are not necessarily indicative of our operating results for any future periods. This press release speaks only as of its date. We assumes no obligation to update the information in this press release, to revise any forward-looking statements or to update the reasons actual events or results could differ materially from those anticipated in forward-looking statements.

Use of Non-GAAP Financial Information

This press release contains financial measures that are not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). Our management evaluates our company’s results and makes operating decisions using various GAAP and non-GAAP measures. In addition to our GAAP results, we also consider non-GAAP gross margin for products and for services, non-GAAP net income/(loss), and non-GAAP earnings per diluted share. We also present Adjusted EBITDA, a non-GAAP measure that we reconcile to net income. These non-GAAP measures should not be considered as a substitute for the corresponding financial measure derived in accordance with GAAP. We present the non-GAAP measures because we consider them to be important supplemental information for our investors for analyzing our performance, core operating results and trends. Investors are encouraged to review the reconciliation of non-GAAP financial measures to their most directly comparable GAAP measures included with this press release.

Our non-GAAP gross margin, non-GAAP net income/(loss), and non-GAAP earnings per diluted share as well as Adjusted EBITDA are exclusive of certain items to facilitate management’s review of the comparability of our core operating results on a period to period basis because such items are not related to our ongoing core operating results as viewed by management. We define our “core operating results” as those revenues recorded in a particular period and the expenses incurred within that period that directly drive operating income in that period. Management uses these non-GAAP financial measures in making operating decisions because, in addition to meaningful supplemental information regarding operating performance, the measures give us a better understanding of how we should invest in research and development, fund infrastructure growth and evaluate the effectiveness of marketing strategies. In calculating the above non-GAAP results, management specifically adjusted for the following excluded items:

a) Stock-based compensation expense impact. We recognize equity plan-related compensation expenses, which represent the fair value of all share-based payments to employees, including grants of employee stock options as non-GAAP adjustments in each period.

b) Amortization of acquired intangibles. We acquired certain companies in 2010 and booked intangible assets related to these acquisitions. The amortization of these acquisition related costs is excluded from non-GAAP net income because it is not related to ongoing controllable management decisions and because it is non-cash in nature.

c) Stock warrant revaluation expenses. This is a non-cash expense as a result of preferred warrants outstanding that were revalued each quarter prior to our initial public offering. We believe the comparisons of ongoing operations should exclude effects of such revaluations.

Management adjusts for the above items because management believes that, in general, these items possess one or more of the following characteristics: their magnitude and timing is largely outside of Vocera’s control; they are unrelated to the ongoing operation of the business in the ordinary course; they are unusual and we do not expect them to occur in the ordinary course of business; or they are non-operational, or non-cash expenses involving stock option grants.

We believe that the presentation of these non-GAAP financial measures is warranted for several reasons:

1) Such non-GAAP financial measures provide an additional analytical tool for understanding our financial performance by excluding the impact of items which may obscure trends in the core operating results of the business;

2) These non-GAAP financial measures facilitate comparisons to the operating results of other companies commonly compared to us, which use similar financial measures to supplement their GAAP results, thus enhancing the perspective of investors who wish to utilize such comparisons in their analysis of our performance; and

3) These non-GAAP financial measures are employed by our management in their own evaluation of performance and are utilized in financial and operational decision making processes, such as budget planning and forecasting.

Set forth below are additional reasons why share-based compensation expense is excluded from our non-GAAP financial measures:

i) While share-based compensation constitutes one of our ongoing and recurring expenses, it is not an expense that requires cash settlement by us. We therefore exclude these charges for purposes of evaluating core operating results. Thus, our non-GAAP measurements are presented exclusive of stock-based compensation expense to assist management and investors in evaluating our core operating results.

ii) We present share-based payment compensation expense in our reconciliation of non-GAAP financial measures on a pre-tax basis because the exact tax differences related to the timing and deductibility of share-based compensation are dependent upon the trading price of our common stock and the timing and exercise by employees of their stock options. As a result of these timing and market uncertainties the tax effect related to share-based compensation expense would be inconsistent in amount and frequency and is therefore excluded from our non-GAAP results.

As stated above, we present non-GAAP financial measures because we consider them to be important supplemental measures of performance. However, non-GAAP financial measures have limitations as an analytical tool and should not be considered in isolation or as a substitute for our GAAP results. In the future, we expect to incur expenses similar to certain of the non-GAAP adjustments described above and expect to continue reporting non-GAAP financial measures excluding such items. Some of the limitations in relying on non-GAAP financial measures are:

Pursuant to the requirements of SEC Regulation G, a detailed reconciliation between our non-GAAP and GAAP financial results is set forth in the financial tables at the end of this press release. Investors are advised to carefully review and consider this information strictly as a supplement to the GAAP results that are contained in this press release and in our SEC filings.
