SEACHANGE INTERNATIONAL REPORTS

FIRST QUARTER FISCAL 2015 RESULTS

ACTON, Mass. (June 5, 2014) – SeaChange International, Inc. (NASDAQ: SEAC), a leading global multi-screen video software innovator, today reported first quarter fiscal 2015 revenue of $24.3 million and a non-GAAP operating loss of $7.2 million, or $0.22 per basic share, from continuing operations. In comparison, first quarter fiscal 2014 revenue was $35.6 million and non-GAAP operating income was $1.2 million, or $0.04 per fully diluted share, from continuing operations. The Company posted U.S. GAAP operating loss of $10.1 million, or $0.31 per basic share, for the first quarter of fiscal 2015, compared to a U.S. GAAP operating loss for the first quarter of fiscal 2014 of $1.8 million, or $0.05 per basic share. The Company’s U.S. GAAP first quarter fiscal 2015 results include charges of $3.0 million that are excluded from its non-GAAP results, which consisted primarily of stock-based compensation and amortization of intangible assets from prior acquisitions.

“In spite of the anticipated short-term challenges, which include significant declines in legacy product revenues and continuing delays in receiving customer acceptances for new products, as well as push outs of expected orders, SeaChange is continuing to invest in R&D to further enhance our next generation software products to support new and existing customer requirements,” said Raghu Rau, CEO, SeaChange. “While these investments impact short-term profitability, we believe they will create long-term value based on continuing customer traction of our next generation products. During the first quarter, we received acceptance of our Adrenalin multi-screen television platform from two service providers that was previously delayed. Since the end of the first quarter, we have also begun to receive orders from three large U.S. service providers that were expected earlier. We also have achieved a new design win with an existing customer for Adrenalin and our Nucleus video gateway software in an additional European country. Based on expected rollouts of our next generation products and customer upgrades, we remain confident that our revenue and profitability will improve sequentially in each of the next three quarters. We also expect to grow second half fiscal 2015 revenues and profitability year over year.”

Anthony Dias, CFO, SeaChange, said, “As we’ve stated previously, our first quarter is typically our lowest period seasonally and this quarter’s results were compounded by significant legacy declines and delays in customer acceptances of new products. We expect our second quarter fiscal 2015 revenues to be in the range of $26 million to $30 million and non-GAAP operating loss between $0.10 and $0.20 per basic share. Driven by orders for our new products and lowered legacy revenue declines in the second half of this year, we expect revenues for full fiscal 2015 to be in the range of $125 million to $135 million and non-GAAP operating results to be in the range of a loss of $0.12 per share to an operating income of $0.10 per share.”

SeaChange ended the first quarter of fiscal 2015 with cash, cash equivalents and marketable securities of $116.6 million and no debt outstanding, compared to $128.1 million at the close of the fourth quarter of fiscal 2014. The Company repurchased $3.5 million of its outstanding shares under its $25 million stock buyback authorization during the first quarter. On May 31, 2014, SeaChange’s Board of Directors amended the plan, increasing the buyback authorization from $25 million to $40 million and extending the termination date of the plan from January 31, 2015 to April 30, 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 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 expense due to changes in fair value related to contingent consideration that we believe would otherwise impair comparability among periods.

Professional Fees: Acquisitions, Divestitures, Litigation and Strategic Alternatives. 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.
