SEACHANGE INTERNATIONAL REPORTS

FIRST QUARTER FISCAL 2016 RESULTS

ACTON, Mass. (June 4, 2015) – SeaChange International, Inc. (NASDAQ: SEAC) today reported first quarter fiscal 2016 revenue of $23.2 million and U.S. GAAP loss from operations of $9.5 million, or $0.28 per basic share, compared to first quarter fiscal 2015 revenue of $24.3 million and U.S. GAAP operating loss of $10.1 million, or $0.31 per basic share. Excluding stock-based compensation, amortization of acquisition-related intangible assets and earn-outs and change in fair value of earn-outs, all of which are non-cash expenses, on a non-GAAP basis adjusted net loss for the first quarter of 2016 was $6.8 million, or $0.20 per basic share, compared to an adjusted net loss of $7.2 million, or $0.22 per basic share, in the first quarter of 2015.

“SeaChange continues to outperform its multiscreen competitors to win the vast majority of opportunities we’ve pursued for our multiscreen television platform and video gateway,” said Jay Samit, Chief Executive Officer, SeaChange. “During the first quarter, a new Canadian service provider customer for SeaChange purchased Adrenalin, replacing the incumbent VOD platform provider. Further, one of our largest U.S. customers, which has over four million subscribers, completed its upgrade from Axiom to Adrenalin to offer multiscreen commercially in 20 markets. Our Nucleus video gateway software was commercially launched for a second Eastern European customer and advanced into field trials for a South American customer. I’m also pleased to announce that one of our largest customers awarded SeaChange with additional multi-million dollar contracts that will expand our set-top footprint across new markets with this customer. We were able to begin work immediately and take partial revenue on one of these contracts during our first quarter.”

Samit continued, “As our core products continue to take hold in markets globally, we’re working aggressively to secure opportunities for a new set of customers with our premium-OTT platform Rave. The message about our OTT differentiation is penetrating globally and we’re engaging with TV networks, broadcasters and niche content owners. In the first quarter of fiscal 2016 alone we responded to more requests for OTT proposals than we had identified for our multiscreen offering throughout all of fiscal 2015. Since we can rapidly establish cloud-based Rave market trials for extensive customer evaluation, we continue to anticipate that the OTT sales cycle will be shorter than it is typically for our on-premise products.”

“As announced this afternoon, I’m very pleased that our effort to reinstitute the COO role within our organization has concluded with the appointment of software industry veteran and SeaChange board member Ed Terino,” said Samit. “Ed is responsible for SeaChange’s software development, sales and service globally. With his extensive insight into our operations and markets, Ed will ensure our ability to further improve operations, augment customer satisfaction, and establish our software products in new markets.”

Anthony Dias, Chief Financial Officer, SeaChange, stated, “In addition to securing new contracts for our core products, we have made substantial progress on controlling our operating costs while delivering on our Adrenalin and Nucleus customer commitments, successfully introducing Rave to the marketplace, and integrating Timeline Labs throughout our organization. Our planned expense reductions remain on track and we anticipate realizing the full benefit of our streamlining efforts during the second half of fiscal 2016.”

Commenting on the Company’s outlook, Dias concluded, “We anticipate second quarter fiscal 2016 revenue to be in the range of $26 million to $28 million, and non-GAAP operating loss to be in the range of $0.15 to $0.09 per basic share. For full fiscal 2016, we continue to anticipate revenues to be in the range of $105 million to $115 million and non-GAAP operating loss to be in the range of $0.38 to $0.16 per basic share. As previously stated, our full year guidance reflects a moderate decrease in product revenue related to our transition to a SaaS model and legacy product revenue declines in the range of $7 million to $10 million. Legacy product revenue is on track to be less than $5 million starting in fiscal 2017. In line with this forecast, SeaChange has begun communicating with its Axiom VOD customers about the end of Axiom support and development by December 31, 2016 and the options for transitioning to the Adrenalin platform.”

During the quarter, the Company utilized $11.7 million in cash for its acquisition of Timeline Labs, which closed on February 2, 2015.

Use of Non-GAAP Financial Information

We define non-GAAP (loss) income from operations as U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) operating (loss) income 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 and severance and other restructuring costs. We discuss non-GAAP (loss) income from operations in our quarterly earnings releases and certain other communications as we believe non-GAAP (loss) income from operations is an important measure that is not calculated according to U.S. GAAP. We use non-GAAP (loss) income 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 (loss) income 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 (loss) income 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 (loss) income 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:

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, selling, general and administrative expense and research and development expense. 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 the 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.

The following table reconciles the Company’s U.S. GAAP (loss) income from operations to the Company’s non-GAAP (loss) income from operations:
