Investor Presentation

2. Safe Harbor
This presentation may contain forward-looking statements and management may make additional forward-looking statements in response to your
questions. These statements are made under the ''safe harbor'' provisions of the U.S. Private Securities Litigation Reform Act of 1995. These forward-
looking statements can be identified by terminology such as “will,” “expects,” “anticipates,” “future,” “intends,” “plans,” “believes,” “estimates” and
similar statements. Statements that are not historical facts, including statements concerning our beliefs, forecasts, estimates and expectations, are
forward-looking statements. Forward-looking statements involve inherent risks and uncertainties that could cause actual results to differ materially
from those projected or anticipated, including risks related to: the risk that our results of operations are cyclical and may fluctuate from period to
period; the risk that we rely on a small number of customers for a significant portion of our revenue; the risk that the industries in which we
participate are highly competitive and other risks outlined in our public filings with the Securities and Exchange Commission, including as set forth
under “Risk Factors”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in our most recent
Quarterly Report on Form 10-Q and Annual Report on Form 10-K filed with the Securities and Exchange Commission. The forward-looking statements
made in this presentation relate only to events or information as of the date on which the statements are made in this presentation. Except as
required by law, we undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information,
future events or otherwise, after the date on which the statements are made or to reflect the occurrence of unanticipated events.
Management uses non-GAAP net income and non-GAAP net income per diluted share to evaluate the Company's operating and financial results. The
Company believes the presentation of non-GAAP results is useful to investors for analyzing our core business and business trends and comparing
performance to prior periods, along with enhancing investors' ability to view the Company's results from management's perspective. The
presentation of this additional information should not be considered a substitute for results prepared in accordance with GAAP. Tables presenting
reconciliations of non-GAAP results to U.S. GAAP results are included in the Appendix.

3. Q4’16 Revenue Guidance Update: approximately $173M vs. $146M - $151M
3 Main Drivers for 2017
– 2017 WFE spending to increase 6% by 3D NAND & node transitions in 10nm Logic & 1x DRAM
– Our primary customers are concentrated in Deposition & Etch; fastest growing areas of WFE
– High OEM factory capacity utilization is driving a strong push for expanded outsourcing
• Share gain opportunities for the strongest suppliers with the broadest capabilities
• Ability to manufacture major modules across the customer’s entire tool is fueling strong growth

Reconciliation: GAAP Net Income to Non-GAAP Net Income
(1) Amortization of intangible assets related to the Company's acquisitions of AIT, Marchi and Miconex
(2) Represents expense for termination benefits paid to former executives of the Company
(3) Adjustment to previous restructuring reserve related to the abandonment of one of the Company's facilities
(4) Costs incurred related to the acquisition of Marchi and Miconex
(5) Tax effect on amortization of intangible assets, executive transition costs, restructuring charges, and acquisition costs based on the non-GAAP tax rate
(6) The Company's GAAP tax expense is substantially higher than the Company's non-GAAP tax expense, primarily due to losses in the U.S. with full federal and state valuation allowances. The Company's non-GAAP tax
rate and resulting non-GAAP tax expense considers the tax implications as if there was no federal or state valuation allowance position in effect
