November 7, 2018

-- Revenue of $71.5 million increased 4.1% from Q2:18 -- Gross margin of 79.6% increased 7.7 percentage points from Q2:18 -- Added seven new cable and fixed telco customers during Q3:18 -- $94.1 million of net cash provided by operating activities and $87.9 million in free cash flow for the nine months ending September 30, 2018 -- Reaffirmed Fiscal 2018 guidance of revenue in the range of $330 million to $350 million and non-GAAP diluted EPS of $0.80 to $0.88

ANDOVER, Mass., Nov. 07, 2018 (GLOBE NEWSWIRE) -- Casa Systems, Inc. (NASDAQ:CASA), a leading provider of converged broadband infrastructure technology solutions for mobile, cable and fixed networks, today announced its financial results for its third quarter ended September 30,2018.

Third Quarter 2018 Financial Highlights

-- Revenue of $71.5 million -- Gross margin of 79.6% -- GAAP net income of $18.9 million -- Non-GAAP net income of $20.6 million -- Adjusted EBITDA of $27.2 million -- GAAP net income per fully diluted share of $0.21 -- Non-GAAP net income per fully diluted share of $0.22

“Our third quarter results were directly in-line with our revised expectations as customers finalized decisions on DAA deployment and digested the hardware capacity they had purchased earlier in the year. In line with this, during the quarter we continued to see a shift in our revenue mix to software capacity expansions across the globe in support of customer demand for gigabit services with DOCSIS 3.0 and 3.1,” said Jerry Guo, Casa’s President and CEO. “Business traction remains strong as we converted two trials into orders, including one for DAA and one for fixed telco, and expanded our overall trials from 49 to 56 across all products. Given the number of trials we are in and the deployment of new products we are starting to see, I remain as optimistic as I have ever been about the outlook for the company.” said Guo.

Commenting on the Company’s financial results, Shaun McCarthy, Casa’s Interim CFO, added, “During the third quarter, we saw continued momentum in software-based capacity expansions, which accounted for 60.4% of product revenue compared to 42.0% in the second quarter of 2018. This led to a substantial increase in our GAAP gross margin to 79.6%, an increase of 7.7 percentage points over the second quarter of 2018. In addition, we continued to diversify our revenue base with the addition of seven new cable and fixed telco customers in the quarter.”

To supplement our financial results presented in accordance with Generally Accepted Accounting Principles (GAAP), we are presenting non-GAAP financial measures in this press release. A reconciliation of GAAP to non-GAAP measures has been provided in the financial statement tables included in this press release. An explanation of these measures is also included below under the heading “Non-GAAP Financial Measures”.

Financial Outlook

For the fiscal year 2018, we expect:

-- Revenue between $330.0 million and $350.0 million -- Gross Margin in a range of high 60s % to low 70s % -- Non-GAAP net income between $76.0 million and $83.0 million -- Non-GAAP diluted net income per share between $0.80 and $0.88

Guidance for non-GAAP financial measures excludes the follow-on public offering expenses, which are a one-time non-recurring charge, stock-based compensation, which is a non-cash charge, and the resulting tax effect of these excluded items. We have not reconciled the non-GAAP metrics as to which we provide guidance to their most directly comparable GAAP metrics because certain items that impact these excluded measures are uncertain, out of our control and/or cannot be reasonably calculated or predicted at this time. Accordingly, a reconciliation of the non-GAAP financial metrics included in our guidance to the corresponding GAAP measures is not available without unreasonable effort.

The words “anticipate”, “believe”, “continue”, “could”, “estimate”, “expect”, “intend”, “may”, “plan”, “potential”, “predict”, “project”, “target”, “should”, “would”, and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. We have based these forward-looking statements on our estimates and assumptions of our financial results and our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs as of the date of this press release. A number of important risk factors could cause actual results to differ materially from the results described, implied or projected in these forward-looking statements. These factors include, without limitation: (1) any failure by us to successfully anticipate technological shifts, market needs and opportunities, and develop new products and product enhancements that meet those technological shifts, needs and opportunities; (2) the concentration of a substantial portion of our revenue in our CCAP solutions and in certain customers; (3) fluctuations in our revenue due to timing of large orders and seasonality; (4) the length and lack of predictability of our sales cycle; (5) any difficulties we may face in expanding our platform into the wireless market; and (6) other factors discussed in the “Risk Factors” section of our public reports filed with the SEC, including our most recent Quarterly Report on Form 10-Q, which is on file with the SEC and available in the investor relations section of our website at http://investors.casa-systems.com and on the SEC’s website at www.sec.gov. In addition, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements that we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this press release are inherently uncertain and may not occur, and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

Non-GAAP Financial Measures

To supplement our financial results presented in accordance with Generally Accepted Accounting Principles (GAAP), we are presenting the following non-GAAP financial measures in this press release and the related earnings conference call: non-GAAP net income, non-GAAP diluted net income per share, adjusted EBITDA and free cash flow. These non-GAAP financial measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similarly titled measures presented by other companies.

Non-GAAP net income and non-GAAP diluted net income per share. We define non-GAAP net income as net income as reported in our condensed consolidated statements of operations, excluding the impact of stock-based compensation expense, which is a non-cash charge, the follow-on public offering expenses, which is a one-time non-recurring charge, and the tax effect on these excluded items. The tax effect of the excluded items is calculated using our effective income tax rate for the period, excluding the discrete tax benefits generated from the exercise of non-qualified stock options and the disqualifying disposition of incentive stock options. We believe that excluding these discrete tax benefits from our effective income tax rate results in more useful disclosure to investors and others regarding income tax effects of the excluded items as these amounts may vary from period to period independent of the operating performance of our business. We define non-GAAP diluted net income per share as diluted net income per share attributable to common stockholders reported in our condensed consolidated statements of operations, excluding the impact of cumulative dividends on convertible preferred stock, which are no longer applicable following the conversion to common stock of all of our outstanding preferred stock in December 2017 in connection with our initial public offering, excluding the impact of dividends declared on convertible preferred stock, as we do not intend to declare any dividends for the foreseeable future, and excluding the impact of items that we exclude in calculating non-GAAP net income. For periods in which convertible preferred stock was excluded from GAAP diluted net income per share attributable to common stockholders, we calculate non-GAAP diluted net income per share using a non-GAAP weighted-average share count in which the impact of dilutive convertible preferred stock are added to the GAAP weighted-average share count. We have presented non-GAAP net income and non-GAAP diluted net income per share because they are key measures used by our management and board of directors to understand and evaluate our operating performance, to establish budgets and to develop operational goals for managing our business. The presentation of non-GAAP net income and non-GAAP diluted net income per share also allows our management and board of directors to make additional comparisons of our results of operations to other companies in our industry.

Adjusted EBITDA. We define adjusted EBITDA as our net income, excluding the impact of stock-based compensation expense; the follow-on public offering expenses; other income (expense), net; depreciation and amortization expense; and our provision for (benefit from) income taxes. We have presented adjusted EBITDA because it is a key measure used by our management and board of directors to understand and evaluate our operating performance, to establish budgets and to develop operational goals for managing our business. In particular, we believe that excluding the impact of these expenses in calculating adjusted EBITDA can provide a useful measure for period-to-period comparisons of our core operating performance.

Free cash flow. We define free cash flow as net cash provided by operating activities minus capital expenditures. We believe free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by our business that, after purchases of property and equipment, can be used for strategic opportunities, including investing in our business, making strategic acquisitions and strengthening our balance sheet.

We use these non-GAAP financial measures to evaluate our operating performance and trends and make planning decisions. We believe that each of these non-GAAP financial measures helps identify underlying trends in our business that could otherwise be masked by the effect of the expenses that we exclude in the calculations of each non-GAAP financial measure. Accordingly, we believe that these financial measures provide useful information to investors and others in understanding and evaluating our operating results, enhancing the overall understanding of our past performance and future prospects.

Our non-GAAP financial measures are not prepared in accordance with GAAP, and should not be considered in isolation of, or as an alternative to, measures prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP financial measures rather than the most directly comparable financial measures calculated and presented in accordance with GAAP. Some of these limitations are:

-- we exclude stock-based compensation expense from each of non-GAAP net income, non-GAAP diluted net income per share and adjusted EBITDA as it has recently been, and will continue to be for the foreseeable future, a significant recurring non-cash expense for our business and an important part of our compensation strategy; -- we exclude the discrete tax benefits generated from the exercise of non-qualified stock options and the disqualifying disposition of incentive stock options, which are not related to the operating performance of our business, in calculating the effective tax rate used to determine the tax effect of the items excluded from our non-GAAP net income and non-GAAP diluted net income per share; these discrete tax benefits will result in a reduction in our income taxes and cash paid for income taxes; -- we exclude the follow-on public offering expenses from non-GAAP net income, non-GAAP diluted net income per share and adjusted EBITDA because it is a one-time non-recurring charge, although this is a use of our cash and included in our operating expenses; -- adjusted EBITDA excludes depreciation and amortization expense and, although this is a non-cash expense, the assets being depreciated and amortized may have to be replaced in the future; -- adjusted EBITDA does not reflect the cash requirements necessary to service interest on our debt or the cash received from our interest-bearing financial assets, both of which impact the cash available to us, and does not reflect foreign currency transaction gains and losses, all of which are reflected in other income (expense), net; -- adjusted EBITDA does not reflect income tax payments that reduce cash available to us; -- free cash flow may not represent our residual cash flow available for discretionary expenditures, since we may have other non-discretionary expenditures that are not deducted from this measure; -- free cash flow may not represent the total increase or decrease in the cash and cash equivalents for any given period because it excludes cash provided by or used for other investing and financing activities; and -- other companies, including companies in our industry, may not use non-GAAP net income, non-GAAP diluted net income per share, adjusted EBITDA or free cash flow, or may calculate such non-GAAP financial measures in a different manner than we do, or may use other non-GAAP financial measures to evaluate their performance, all of which could reduce the usefulness of these non-GAAP financial measures as comparative measures.

For the 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 Selected GAAP and Non-GAAP Financial Measures”.
