Mentor Graphics Reports Fiscal Fourth Quarter Results

WILSONVILLE, Ore.--(BUSINESS WIRE)--March 3, 2016--Mentor Graphics Corporation (NASDAQ: MENT) today announced financial results for the company’s fiscal fourth quarter ended January 31, 2016. The company reported revenues of $337.3 million, non-GAAP earnings per share of $0.63, and GAAP earnings per share of $0.51. For the full fiscal year, revenues were $1.181 billion, non-GAAP earnings per share were $1.55 and GAAP earnings per share were $0.81.

“Mentor achieved revised fourth quarter and full year revenue guidance and exceeded earnings per share guidance,” said Walden C. Rhines, chairman and CEO of Mentor Graphics. “Fiscal 2016 was our most challenging year since the financial crisis of 2009. Although the semiconductor industry is going through a period of weakness that impacts the EDA industry, Mentor is benefiting from its leading position in design of electronics for the automotive and aerospace industries. Bookings in the automotive part of Mentor’s business grew 20% in the fourth quarter, continuing the 20% compound growth rate of the past five years.”

During the quarter the company announced the embedded industry’s first end-to-end internet of things (IoT) solution that includes customizable gateway hardware and software, cloud services, and edge devices. Mentor’s Veloce® Power application, introduced earlier in the year, was named by EDN Magazine one of the year’s “100 Hot Products”. The company also introduced new versions of three products: the market-leading FloTHERM® and general-purpose FloEFD™ software for computational fluid dynamics, and the Valor® Process Preparation software for electronics manufacturing.

The company made several announcements in the transportation space. A trio of new Capital Systems™ tools enable cost and weight optimization in the automotive and aerospace markets. The Mentor Automotive A²B Analyzer™ is the industry’s first third-party development platform supporting the Analog Devices, Inc. Automotive Audio Bus A²B technology. The combination reduces development time, cost and complexity of in-vehicle audio networks. In other automotive news, electrical systems for all new General Motors vehicle platforms are now being designed using Capital® tools, with design data for existing vehicle platforms also being converted to Capital software.

“Through rigorous attention to expenses we reduced fourth quarter operating costs by $20 million and exceeded non-GAAP earnings per share by $0.16 compared to guidance,” said Gregory K. Hinckley, president of Mentor Graphics. “Full-year non-GAAP operating margins exceeded 20% and cash flow from operations increased 65% to a record of nearly $230 million. Since reporting third quarter results Mentor has repurchased over 12 million shares and reduced our shares outstanding by approximately 10%.”

Outlook

For the first quarter of fiscal 2017, the company expects revenues of about $220 million, a non-GAAP earnings per share of break-even and a GAAP loss per share of approximately $0.12. For the full year fiscal 2017, the company expects revenues of about $1.215 billion, non-GAAP earnings per share of about $1.68, and GAAP earnings per share of approximately $1.22. Cash flow from operations in fiscal 2017 is expected to be approximately $200 million.

Dividend

The company announced a quarterly dividend of $0.055 per share. The dividend is payable on March 31, 2016 to shareholders of record at the close of business on March 10, 2016.

Fiscal Year Definition

Mentor Graphics Corporation’s fiscal year runs from February 1 to January 31. The fiscal year is dated by the calendar year in which the fiscal year ends. As a result, the first three fiscal quarters of any fiscal year will be dated with the next calendar year, rather than the current calendar year.

Discussion of Non-GAAP Financial Measures

Mentor Graphics’ management evaluates and makes operating decisions using various performance measures. In addition to our GAAP results, we also consider adjusted gross profit, operating income, operating margin, net income, and earnings per share which we refer to as non-GAAP gross profit, operating income, operating margin, net income, and earnings per share, respectively. These non-GAAP measures are derived from the revenues of our product, maintenance, and services business operations and the costs directly related to the generation of those revenues, such as cost of revenue, research and development, marketing and sales, and general and administrative expenses, that management considers in evaluating our ongoing core operating performance. These non-GAAP measures exclude amortization of intangible assets, special charges, equity plan-related compensation expenses, interest expense associated with the amortization of original issuance debt discount on convertible debt, the equity in earnings or losses of unconsolidated entities (except Frontline PCB Solutions Limited Partnership (Frontline)), and the impact on basic and diluted earnings per share of changes in the calculated redemption value of noncontrolling interests, which management does not consider reflective of our core operating business.

Management excludes from our non-GAAP measures certain recurring items to facilitate its review of the comparability of our core operating performance on a period-to-period basis because such items are not related to our ongoing core operating performance as viewed by management. Management considers our core operating performance to be that which can be affected by our managers in any particular period through their management of the resources that affect our underlying revenue and profit generating operations during that period. Management uses this view of our operating performance for purposes of comparison with our business plan and individual operating budgets and allocation of resources. Additionally, when evaluating potential acquisitions, management excludes the items described above from its consideration of target performance and valuation. More specifically, management adjusts for the excluded items for the following reasons:

• Identified intangible assets consist primarily of purchased technology, backlog, trade names, and customer relationships. Amortization charges for our intangible assets can vary in frequency and amount due to the timing and magnitude of acquisition transactions. We consider our operating results without these charges when evaluating our core performance due to the variability. Generally, the most significant impact to inter-period comparability of our net income is in the first twelve months following an acquisition.
• Special charges may include expenses related to employee severance, certain litigation costs, acquisitions, excess facility costs, and other asset related charges. Special charges are incurred based on particular facts and circumstances and can vary in size and frequency. Restructuring costs included in special charges include costs incurred for employee terminations, including severance and benefits, driven by modification of business strategy or business emphasis. Litigation costs classified as special charges consist of professional service fees related to patent litigation involving us, EVE S.A., and Synopsys, Inc. These costs are included in special charges because of their unusual nature due to the significance in variability of timing and amount. Special charges are not ordinarily included in our annual operating plan and related budget due to unpredictability, driven in part by rapidly changing technology and the competitive environment in our industry. We therefore exclude them when evaluating our managers’ performance internally.
• Equity plan-related compensation expenses represent the fair value of all share-based payments to employees, including grants of employee stock options and restricted stock units, and purchases made as a result of our employee stock purchase plans. We do not consider equity plan-related compensation expense in evaluating our managers’ performance internally or our core operations in any given period.
• Interest expense attributable to amortization of the original issuance debt discount on convertible debt is excluded. Management does not consider this charge as a part of our core operating performance. We do not consider the amortization of the original issuance debt discount on convertible debt to be a direct cost of operations.
• Equity in earnings or losses of unconsolidated entities represents our equity in the net income (loss) of common stock investments accounted for under the equity method. The carrying amounts of our investments are adjusted for our share of earnings or losses of the investee. We report our equity in the earnings or losses of investments in other income (expense), net (with the exception of our investment in Frontline as discussed below). The amounts are excluded from our non-GAAP results as we do not control the results of operations for the investments and we do not participate in regular and periodic operating activities; therefore, management does not consider these investments as a part of our core operating performance.
• The Company maintains a 50% interest in Frontline, a joint venture. We report our equity in the earnings or losses of Frontline within operating income. Although we do not exert control, we actively participate in regular and periodic activities such as budgeting, business planning, marketing and direction of research and development projects. Accordingly, we do not exclude our share of Frontline’s earnings or losses from our non-GAAP results as management considers the joint venture to be core to our operating performance.
• Income tax expense is adjusted by the amount of additional tax expense or benefit that we would accrue if we used non-GAAP results instead of GAAP results in the calculation of our tax liability, utilizing a normalized effective tax rate. Our GAAP tax rate for the year ended January 31, 2016 is 20.8%. Our normalized non-GAAP effective tax rate for the year ended January 31, 2016 is 19%. The normalized non-GAAP effective tax rate considers our global tax posture, including the weighted average tax rates applicable in the various jurisdictions in which we operate; eliminates the effects of non-recurring and period specific items which are often attributable to acquisition decisions and can vary in size and frequency; and considers our U.S. tax loss carryforwards and tax credits that were not previously recorded as a benefit in our financial statements. Our non-GAAP effective tax rate is subject to change over time for various reasons, including changes in geographic business mix, statutory tax rates, foreign re-investment expectations, and availability of U.S. tax loss carryforwards and tax credits that were not previously recorded as a benefit. Our normalized effective non-GAAP tax rate for the year ended January 31, 2017 is expected to be 19% which is consistent with the year ended January 31, 2016.
• Our agreement with the former owners of noncontrolling interests in one of our subsidiaries gave them a right to require us to purchase their interests for a price based on a formula defined in the agreement. Under GAAP, increases (or decreases to the extent they offset previous increases) in the calculated redemption value of the noncontrolling interests are recorded directly to retained earnings and therefore do not affect net income. However, as required by GAAP, these amounts are applied to increase or decrease the numerator in the calculation of basic and diluted earnings per share. In September 2015 we acquired the remaining noncontrolling interest in the subsidiary. The amount for the twelve months ended January 31, 2016 reflects the final adjustment of redemption value to the actual price we paid. Management does not consider fluctuations in the calculated redemption value of noncontrolling interests to be relevant to our core operating performance.

In certain instances our GAAP results of operations may not be profitable when our corresponding non-GAAP results are profitable or vice versa. The number of shares on which our non-GAAP earnings per share is calculated may therefore differ from the GAAP presentation due to the anti-dilutive effect of stock options, restricted stock units, employee stock purchase plan shares, and convertible debt in a loss situation.

Non-GAAP gross profit, operating income, operating margin, net income, and earnings per share are supplemental measures of our performance that are not presented in accordance with GAAP. Moreover, they should not be considered as an alternative to any performance measure derived in accordance with GAAP, or as an alternative to cash flow from operating activities as a measure of our liquidity. We present non-GAAP gross profit, operating income, operating margin, net income, and earnings per share because we consider them to be important supplemental measures of our operating performance and profitability trends, and because we believe they give investors useful information on period-to-period performance as evaluated by management. Non-GAAP net income also facilitates comparison with other companies in our industry, which use similar financial measures to supplement their GAAP results. Non-GAAP net income has limitations as an analytical tool, and therefore should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. In the future, we expect to continue to incur expenses similar to the non-GAAP adjustments described above and exclusion of these items in our non-GAAP presentation should not be construed as an inference that these costs are unusual, infrequent or non-recurring. Some of the limitations in relying on non-GAAP net income are:

• Amortization of intangible assets represents the loss in value as the technology in our industry evolves, is advanced, or is replaced over time. The expense associated with this loss in value is not included in the non-GAAP net income presentation and therefore does not reflect the full economic effect of the ongoing cost of maintaining our current technological position in our competitive industry, which is addressed through our research and development program.
• We regularly evaluate our business to determine whether any operations should be eliminated or curtailed. Additionally, as part of our ongoing business, we engage in acquisition and assimilation activities and patent litigation. We therefore will continue to experience special charges on a regular basis. These costs also directly impact our available funds.
• Our stock incentive and stock purchase plans are important components of our incentive compensation arrangements and will be reflected as expenses in our GAAP results.
• Our income tax expense will be ultimately based on our GAAP taxable income and actual tax rates in effect, which often differ significantly from the rate assumed in our non-GAAP presentation. In addition, if we have a GAAP loss and non-GAAP net income, our non-GAAP results will not reflect any projected GAAP tax benefits.
• Other companies, including other companies in our industry, calculate non-GAAP net income differently than we do, limiting its usefulness as a comparative measure.
