CAUTIONARY STATEMENT

This Annual Report on Form 10-K (“Annual Report”) contains forward-looking statements, including statements regarding our business outlook, strategic plans and priorities, expectations, anticipated drivers of future revenue growth, industry trends, our plans for use of our cash and cash equivalents and short-term investments, our ability to meet working capital requirements, estimates and objectives for future operations, our future results of operations and our financial position. Forward-looking statements generally may be identified by terms such as “anticipates,” “believes,” “could,” “continue,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “projects,” “seeks,” “should,” “targets,” “will,” “would” or similar expressions or variations or the negatives of those terms.

Forward-looking statements are neither historical facts nor assurances about future performance. Instead, they are based only on our current beliefs, expectations and assumptions. Because forward-looking statements relate to the future, such statements involve inherent risks, changes and uncertainties that are difficult to predict and many of which are outside of our control. A number of important factors could cause actual results and outcomes to differ materially and adversely from those expressed or implied by our forward-looking statements. We urge you to consider the risks and uncertainties in “Item 1A - Risk Factors” and elsewhere in this Annual Report and the other documents filed by us with the Securities and Exchange Commission (the “SEC”). Except as required by law, we undertake no obligation to revise or update our forward-looking statements to reflect any event or circumstance that may arise after the date of this Annual Report.

In this document, the words “MACOM,” “Company,” “we,” “our,” “us,” and similar terms refer only to MACOM Technology Solutions Holdings, Inc. and its consolidated subsidiaries, and not any other person or entity.
