FOURTH QUARTER AND FULL FISCAL 2016 RESULTS

Company Guides for Growth and Profitability for Full Fiscal Year 2017

ACTON, Mass. (April 7, 2016) – SeaChange International, Inc. (NASDAQ: SEAC) today announced results of its operations for the fourth quarter of fiscal 2016 ended January 31, 2016. In a simultaneous announcement made today, Ed Terino has been appointed Chief Executive Officer, effective April 6, 2016.

SeaChange reported fourth quarter fiscal 2016 revenue of $27.2 million and U.S. GAAP loss from operations of $22.1 million, or $0.66 per basic share for the fourth quarter of fiscal 2016, compared to fourth quarter fiscal 2015 revenue of $31.3 million and U.S. GAAP operating loss of $5.3 million, or $0.16 per basic share. The Company’s U.S. GAAP fourth quarter fiscal 2016 results included non-GAAP charges of $22.3 million, which consisted primarily from the loss from impairment of Timeline Labs net assets, severance and other restructuring costs, stock-based compensation, amortization of intangible assets from prior acquisitions, and other non-operating expense professional fees, while the fourth quarter fiscal 2015 results included non-GAAP charges of $3.6 million of similar non-GAAP charges. Non-GAAP income from operations for the fourth quarter of fiscal 2016 was $0.1 million, or break-even per share, compared to non-GAAP loss from operations of $1.7 million, or $0.05 per basic share, in the fourth quarter of fiscal 2015.

For the full fiscal year ended January 31, 2016, the Company posted revenues of $107.0 million and U.S. GAAP operating loss of $48.2 million, or $1.44 per basic share, compared to revenues of $115.4 million and U.S. GAAP operating loss of $26.5 million, or $0.81 per basic share, from operations in the same prior period. The Company posted a non-GAAP loss from operations for fiscal 2016 of $7.5 million, or $0.23 per basic share, compared to a $13.8 million operating loss, or $0.42 per basic share, from continuing operations for the same prior period. Included in the full fiscal 2016 U.S. GAAP results are $40.7 million in non-GAAP charges, which consisted primarily from the loss from impairment of Timeline Labs net assets, severance and other restructuring costs, stock-based compensation, amortization of intangible assets from prior acquisitions, and other non-operating expense professional fees, while the full fiscal 2015 results included $12.7 million of similar non-GAAP charges.

“While we are disappointed in our fiscal 2016 financial performance, we did make significant operational improvements during the year. As we enter fiscal 2017, we intend to further increase operational efficiencies and deliver new software product innovations that capitalize on our core competencies in video delivery, content management and monetization,” said Ed Terino, Chief Executive Officer, SeaChange. “Specifically we will be focused on leveraging our R&D investments and becoming more efficient with our spending as we roll out our platforms for current customer commitments and introduce new cloud-based software products that provide opportunities in our core TV service provider segment, as well as adjacent markets. In addition, we are investing in our sales and marketing capabilities in response to these market opportunities. We believe that these actions will enable SeaChange to return to revenue growth and profitability on a full year basis in fiscal 2017.”

Anthony Dias, Chief Financial Officer, SeaChange, said, “As previously disclosed, we have implemented cost-saving actions with respect to restructuring our Timeline operations and the termination of our prior CEO, Jay Samit, which will enable us to achieve annualized cost savings of approximately $7 million.”

Commenting on the Company’s outlook, Dias concluded, “Generally our first quarter tends to be down cyclically, therefore we anticipate our first quarter fiscal 2017 revenue to be in the range of $20 million to $22 million, and non-GAAP operating loss to be in the range of $0.18 to $0.24 per basic share. For full fiscal 2017, we anticipate revenues to be in the range of $110 million to $120 million and non-GAAP operating income to be in the range of $0.05 to $0.15 per fully diluted share.”

SeaChange continues to have a strong balance sheet and ended the fourth quarter of fiscal 2016 with cash, cash equivalents, restricted cash and marketable securities of $71.1 million and no debt outstanding.

The Company will host a conference call to discuss its fourth quarter and full fiscal 2016 results at 5:00 p.m. ET today, Thursday, April 7, 2016.

Use of Non-GAAP Financial Information

We define non-GAAP income (loss) from operations as U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) operating loss plus stock-based compensation expenses, amortization of intangible assets, earn-outs and change in fair value of earn-outs, professional fees associated with acquisitions, divestitures, litigation and strategic alternatives, severance and other restructuring costs and provision for loss contracts. We discuss non-GAAP income (loss) from operations in our quarterly earnings releases and certain other communications as we believe non-GAAP income (loss) from operations is an important measure that is not calculated according to U.S. GAAP. We use non-GAAP income (loss) from operations in internal forecasts and models when establishing internal operating budgets, supplementing the financial results and forecasts reported to our Board of Directors, determining a component of bonus compensation for executive officers and other key employees based on operating performance and evaluating short-term and long-term operating trends in our operations. We believe that non-GAAP income (loss) from operations assists in providing an enhanced understanding of our underlying operational measures to manage the business, to evaluate performance compared to prior periods and the marketplace, and to establish operational goals. We believe that these non-GAAP financial adjustments are useful to investors because they allow investors to evaluate the effectiveness of the methodology and information used by management in our financial and operational decision-making.

Non-GAAP income (loss) from operations is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with U.S. GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies. We expect to continue to incur expenses similar to the non-GAAP income (loss) from operations financial adjustments described above, and investors should not infer from our presentation of this non-GAAP financial measure that these costs are unusual, infrequent or non-recurring.

In managing and reviewing our business performance, we exclude a number of items required by U.S. GAAP. Management believes that excluding these items is useful in understanding the trends and managing our operations. We provide these supplemental non-GAAP measures in order to assist the investment community to see SeaChange through the “eyes of management,” and therefore enhance the understanding of SeaChange’s operating performance. Non-GAAP financial measures should be viewed in addition to, and not as an alternative to, our reported results prepared in accordance with U.S. GAAP. Our non-GAAP financial measures reflect adjustments based on the following items:

Provision for Loss Contract. We entered into a fixed priced customer contract on a multi-year arrangement, which included multiple vendors. As the system integrator on the project, we are subject to any cost overruns or increases with these vendors resulting in delays or acceptance by our customer. Delays of customer acceptance on this project require us to recognize a loss on this project in the period the determination is made. As a result, we have recorded an estimated charge of $9.2 million during the third quarter of fiscal 2016. We believe that the exclusion of these expenses allows a comparison of operating results that would otherwise impair comparability between periods. As noted previously, the Company is finalizing the amount of the charge. Variation in this amount is not anticipated to impact the Company’s non-GAAP results in the period ending October 31, 2015. The Company will include the final amount of this estimated loss in its Quarterly Report on Form 10-Q for the period ended October 31, 2015.

Amortization of Intangible Assets. We incur amortization expense of intangible assets related to various acquisitions that have been made in recent years. These intangible assets are valued at the time of acquisition, are then amortized over a period of several years after the acquisition and generally cannot be changed or influenced by management after the acquisition. We believe that exclusion of these expenses allows comparisons of operating results that are consistent over time for both the Company’s newly-acquired and long-held businesses.

Stock-based Compensation Expense. We incur expenses related to stock-based compensation included in our U.S. GAAP presentation of cost of revenues and stock-based expenses. Although stock-based compensation is an expense we incur and is viewed as a form of compensation, the expense varies in amount from period to period, and is affected by market forces that are difficult to predict and are not within the control of management, such as the market price and volatility of our shares, risk-free interest rates and the expected term and forfeiture rates of the awards.

Earn-outs and Change in Fair Value of Earn-outs. Earn-outs and the change in the fair value of earn-outs are considered by management to be non-recurring expenses to the former shareholders of the businesses we acquire. We also incur expenses due to changes in fair value related to contingent consideration that we believe would otherwise impair comparability among periods.

Professional Fees - Other. We have excluded the effect of legal and other professional fees associated with our acquisitions, divestitures, litigation and strategic alternatives because the amounts are largely considered to be significant non-operating expenses.

Severance and Other Restructuring. We incur charges due to the restructuring of our business, including severance charges and facility reductions resulting from our restructuring and streamlining efforts and any changes due to revised estimates, which we generally would not have otherwise incurred in the periods presented as part of our continuing operations.

Loss on Impairment of TLL, LLC Net Assets. We incurred an impairment charge relating to our February 2015 acquisition of Timeline Labs, based on our decision to undertake a restructuring which may include a winding down of the operations. These charges are considered non-recurring.

Depreciation Expense. We incur depreciation expense related to capital assets purchased to support the ongoing operations of the business. These assets are recorded at cost and are depreciated using the straight-line method over the useful life of the asset. Purchases of such assets may vary significantly from period to period and without any correlation to underlying operating performance. Management believes that exclusion of depreciation expense allows comparisons of operating results that are consistent across past, present and future periods.
