ANDOVER, Mass., Jan. 29, 2019 (GLOBE NEWSWIRE) — Mercury Systems, Inc. (NASDAQ: MRCY, www.mrcy.com), reported operating results for the second quarter of fiscal 2019, ended December 31, 2018.

Management Comments
“The business performed extremely well in the second quarter of fiscal year 2019,” said Mark Aslett, Mercury’s President and Chief Executive Officer. “We delivered record revenue and continued strong bookings growth which led to a record ending total backlog. We exceeded our guidance for revenue and profitability in addition to delivering strong cash flow. We continued to execute well on our strategy growing organic revenues by 11% year over year as well as completing our fifth strategic acquisition in the C4I market over the past two fiscal years. Given our very strong performance in the first half of fiscal 2019, our record backlog and current business outlook we are raising our full year guidance,” concluded Aslett.

Second Quarter Fiscal 2019 Results
Total Company second quarter fiscal 2019 revenues were $159.1 million, compared to $117.9 million in the second quarter of fiscal 2018.

Acquisition of GECO Avionics, LLC
On January 29th, 2019, the Company also announced the acquisition of GECO Avionics, LLC (“GECO”). Based in Mesa, AZ, GECO has over twenty years of experience designing and manufacturing affordable safety-critical avionics and mission computing solutions. GECO’s DO-254 certified hardware solutions include mission processors, airborne displays, video processing and aviation networking. GECO also specializes in DO-178 avionics software design up to DAL-A, the highest level of design assurance for flight management, aircraft condition monitoring, display and electronic flight instrumentation applications. GECO’s technologies are deployed on numerous military platforms such as the AH-64 Apache attack helicopter and the KC-46A Pegasus widebody multirole tanker, among others.

Mercury acquired GECO for an all cash purchase price of $36.5 million, subject to net working capital and net debt adjustments. The acquisition and associated transaction expenses were funded through Mercury’s existing revolving credit facility.

“The acquisition of GECO complements our acquisitions of Creative Electronic Systems (“CES”), based in Geneva, Switzerland, and Richland Technologies (“RTL”), based in Duluth, GA,” said Mark Aslett, Mercury’s President and Chief Executive Officer. “Combined, these three acquisitions significantly expand our footprint in mission computing and platform management. The safety-critical capabilities these companies provide, along with our high-performance sensor processing solutions and embedded security features will enable us to deliver a compelling combination of electronics offerings that are in high demand from our customers. These new capabilities continue to expand Mercury’s addressable market in the C4I market segment. We are the only high tech commercial company we know of that has brought all of these capabilities together,” Aslett concluded.

Business Outlook
This section presents our current expectations and estimates, given current visibility, on our business outlook for the current fiscal quarter and fiscal year 2019. It is possible that actual performance will differ materially from the estimates given, either on the upside or on the downside. Investors should consider all of the risks with respect to these estimates, including those listed in the Safe Harbor Statement below and in the Second Quarter Fiscal 2019 Earnings Presentation and in our periodic filings with the U.S. Securities and Exchange Commission, and make themselves aware of how these risks may impact our actual performance.

For the third quarter of fiscal 2019, inclusive of the acquisition of GECO, revenues are forecasted to be in the range of $162.7 million to $167.7 million. GAAP net income for the third quarter is expected to be approximately $10.8 million to $12.3 million, or $0.23 to $0.26 per share, assuming no incremental restructuring, acquisition, other non-operating adjustments or non-recurring financing related expenses in the period, an effective tax rate of approximately 27%, excluding discrete items, and approximately 47.9 million weighted average diluted shares outstanding. Adjusted EBITDA for the third quarter of fiscal 2019 is expected to be in the range of $34.8 million to $36.8 million. Adjusted EPS is expected to be in the range of $0.43 to $0.46 per share.

For the full fiscal year 2019, we currently expect revenue of $631.0 million to $646.0 million, and GAAP net income of $42.6 million to $46.1 million, or $0.89 to $0.96 per share, assuming no incremental restructuring, acquisition, other non-operating adjustments or non-recurring financing related expenses in the period, an effective tax rate of approximately 27%, excluding discrete items, and approximately 47.8 million weighted average diluted shares outstanding. Adjusted EBITDA for the full fiscal year is expected to be approximately $138.6 million to $143.5 million, and adjusted EPS for the full fiscal year is expected to be approximately $1.72 to $1.80 per share.

Use of Non-GAAP Financial Measures
In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, the Company provides adjusted EBITDA, adjusted income, adjusted earnings per share (“adjusted EPS”), free cash flow, organic revenue and acquired revenue, which are non-GAAP financial measures. Adjusted EBITDA, adjusted income, and adjusted EPS exclude certain non-cash and other specified charges.

However, these non-GAAP measures should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. Management believes these non-GAAP measures assist in providing a more complete understanding of the Company’s underlying operational results and trends, and management uses these measures along with the corresponding GAAP financial measures to manage the Company’s business, to evaluate its performance compared to prior periods and the marketplace, and to establish operational goals. A reconciliation of GAAP to non-GAAP financial results discussed in this press release is contained in the attached exhibits.

UNAUDITED SUPPLEMENTAL INFORMATION RECONCILIATION OF GAAP TO NON-GAAP MEASURES
(In thousands)

Adjusted EBITDA, a non-GAAP measure for reporting financial performance, excludes the impact of certain items and, therefore, has not been calculated in accordance with GAAP. Management believes that exclusion of these items assists in providing a more complete understanding of the Company’s underlying results and trends, and management uses these measures along with the corresponding GAAP financial measures to manage the Company’s business, to evaluate its performance compared to prior periods and the marketplace, and to establish operational goals. The adjustments to calculate this non-GAAP financial measure, and the basis for such adjustments, are outlined below:

Other non-operating adjustments.  The Company records other non-operating adjustments such as gains or losses on foreign currency remeasurement and fixed asset sales or disposals among other adjustments. These adjustments may vary from period to period without any direct correlation to underlying operating performance.

Interest income and expense.  The Company receives interest income on investments and incurs interest expense on loans, capital leases and other financing arrangements. These amounts may vary from period to period due to changes in cash and debt balances and interest rates driven by general market conditions or other circumstances outside of the normal course of Mercury’s operations.

Income taxes.  The Company’s GAAP tax expense can fluctuate materially from period to period due to tax adjustments that are not directly related to underlying operating performance or to the current period of operations.

Depreciation.  The Company incurs depreciation expense related to capital assets purchased to support the ongoing operations of the business.  These assets are recorded at cost or fair value 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 direct correlation to underlying operating performance.

Amortization of intangible assets.  The Company incurs amortization of intangibles related to various acquisitions it has made and license agreements. These intangible assets are valued at the time of acquisition, are amortized over a period of several years after acquisition and generally cannot be changed or influenced by management after acquisition.

Restructuring and other charges.  The Company incurs restructuring and other charges in connection with management’s decisions to undertake certain actions to realign operating expenses through workforce reductions and the closure of certain Company facilities, businesses and product lines. The Company’s adjustments reflected in restructuring and other charges are typically related to acquisitions and organizational redesign programs initiated as part of discrete post-acquisition integration activities. Management believes these items are non-routine and may not be indicative of ongoing operating results.

Impairment of long-lived assets.  The Company incurs impairment charges of long-lived assets based on events that may or may not be within the control of management. Management believes these items are outside the normal operations of the Company’s business and are not indicative of ongoing operating results.

Acquisition and financing costs.  The Company incurs transaction costs related to acquisition and potential acquisition opportunities, such as legal, accounting, and other third party advisory fees.  Although we may incur such third-party costs and other related charges and adjustments, it is not indicative that any transaction will be consummated. Additionally, the Company incurs unused revolver and bank fees associated with maintaining its credit facility. The Company also incurs non-cash financing expenses associated with obtaining its credit facility. Management believes these items are outside the normal operations of the Company’s business and are not indicative of ongoing operating results.

Fair value adjustments from purchase accounting.  As a result of applying purchase accounting rules to acquired assets and liabilities, certain fair value adjustments are recorded in the opening balance sheet of acquired companies. These adjustments are then reflected in the Company’s income statements in periods subsequent to the acquisition. In addition, the impact of any changes to originally recorded contingent consideration amounts are reflected in the income statements in the period of the change. Management believes these items are outside the normal operations of the Company and are not indicative of ongoing operating results.

Litigation and settlement income and expense. The Company periodically receives income and incurs expenses related to pending claims and litigation and associated legal fees and potential case settlements and/or judgments.  Although we may incur such costs and other related charges and adjustments, it is not indicative of any particular outcome until the matter is fully resolved. Management believes these items are outside the normal operations of the Company’s business and are not indicative of ongoing operating results. The Company periodically receives warranty claims from customers and makes warranty claims towards its vendors and supply chain. Management believes the expenses and gains associated with these recurring warranty items are within the normal operations and operating cycle of the Company’s business. Therefore, management deems no adjustments are necessary unless under extraordinary circumstances.

Stock-based and other non-cash compensation expense.  The Company incurs expense related to stock-based compensation included in its GAAP presentation of cost of revenues, selling, general and administrative expense and research and development expense. The Company also incurs non-cash based compensation in the form of pension related expenses. Although stock-based and other non-cash compensation is an expense of the Company and viewed as a form of compensation, these expenses vary in amount from period to period, and are 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 the Company’s shares, risk-free interest rates and the expected term and forfeiture rates of the awards, as well as pension actuarial assumptions. Management believes that exclusion of these expenses allows comparisons of operating results to those of other companies, both public, private or foreign, that disclose non-GAAP financial measures that exclude stock-based compensation and other non-cash compensation.

Mercury uses adjusted EBITDA as an important indicator of the operating performance of its business.  Management excludes the above-described items from its internal forecasts and models when establishing internal operating budgets, supplementing the financial results and forecasts reported to the Company’s board of directors, determining the portion of bonus compensation for executive officers and other key employees based on operating performance, evaluating short-term and long-term operating trends in the Company’s operations, and allocating resources to various initiatives and operational requirements. The Company believes that adjusted EBITDA permits a comparative assessment of its operating performance, relative to its performance based on its GAAP results, while isolating the effects of charges that may vary from period to period without any correlation to underlying operating performance. The Company believes 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 its financial and operational decision-making. The Company believes that trends in its adjusted EBITDA are valuable indicators of its operating performance.

Adjusted EBITDA is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies. The Company expects to continue to incur expenses similar to the adjusted EBITDA financial adjustments described above, and investors should not infer from the Company’s presentation of this non-GAAP financial measure that these costs are unusual, infrequent or non-recurring.

The following table reconciles the most directly comparable GAAP financial measure to the non-GAAP financial measure.

(1) As of July 1, 2018, the Company has revised its definition of adjusted EBITDA to incorporate other non-operating adjustments, net, which includes gains or losses on foreign currency remeasurement and fixed assets sales and disposals among other adjustments. Adjusted EBITDA for prior periods has been recast for comparative purposes.

Free cash flow, a non-GAAP measure for reporting cash flow, is defined as cash provided by operating activities less capital expenditures and, therefore, has not been calculated in accordance with GAAP. Management believes free cash flow provides investors with an important perspective on cash available for investment and acquisitions after making capital investments required to support ongoing business operations and long-term value creation. The Company believes that trends in its free cash flow are valuable indicators of its operating performance and liquidity.

Free cash flow is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies. The Company expects to continue to incur expenditures similar to the free cash flow financial adjustment described above, and investors should not infer from the Company’s presentation of this non-GAAP financial measure that these expenditures reflect all of the Company’s obligations which require cash.

The following table reconciles the most directly comparable GAAP financial measure to the non-GAAP financial measure.

Adjusted income and adjusted earnings per share (“adjusted EPS”) are non-GAAP measures for reporting financial performance, exclude the impact of certain items and, therefore, have not been calculated in accordance with GAAP. Management believes that exclusion of these items assists in providing a more complete understanding of the Company’s underlying results and trends and allows for comparability with our peer company index and industry. These non-GAAP financial measures may not be computed in the same manner as similarly titled measures used by other companies. The Company uses these measures along with the corresponding GAAP financial measures to manage the Company’s business and to evaluate its performance compared to prior periods and the marketplace. The Company defines adjusted income as income before amortization of intangible assets, restructuring and other charges, impairment of long-lived assets, acquisition and financing costs, fair value adjustments from purchase accounting, litigation and settlement income and expense, and stock-based and other non-cash compensation expense. The impact to income taxes includes the impact to the effective tax rate, current tax provision and deferred tax provision (1). Adjusted EPS expresses adjusted income on a per share basis using weighted average diluted shares outstanding.

Organic revenue and acquired revenue are non-GAAP measures for reporting financial performance of its business. Management believes this information provides investors with insight as to the Company’s ongoing business performance. Organic revenue represents total company revenue excluding net revenue from acquired companies for the first four full quarters since the entities’ acquisition date (which excludes intercompany transactions). Acquired revenue represents revenue from acquired companies for the first four full quarters since the entities’ acquisition date (which excludes intercompany transactions). After the completion of four full fiscal quarters, acquired revenue is treated as organic for current and comparable historical periods.
