"With our family of insulin pumps, we are well-positioned to meet our goals in 2016 and further our mission to improve the lives of people with diabetes."

Forward-Looking Statement

This press release contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that concern matters that involve risks and uncertainties that could cause actual results to differ materially from those anticipated or projected in the forward-looking statements. These forward-looking statements relate to the Company's ability to meet its financial goals and further its mission, the Company's projected financial results, including its ability to achieve additional operating margin improvement and sustain sales momentum for 2016, and the Company's ability to manage its business toward profitability. The Company's actual results may differ materially from those indicated in these forward-looking statements due to numerous risks and uncertainties. For instance, successful commercialization of the Company's products may be negatively impacted by lack of market acceptance by physicians and people with diabetes; the potential that newer products that compete with the Company's products, or other technological breakthroughs for the monitoring, treatment or prevention of diabetes (including new products offered by Dexcom), may render the Company's products obsolete or less desirable; and the potential that the pump purchasing process, including insurance verification approval for individual customers, may be more difficult or time-consuming than it has historically, thereby increasing the risk that sales of the pumps will be delayed or prevented. Other risks and uncertainties include the Company's inability to manufacture products in commercial quantities at an acceptable cost and in accordance with quality requirements; the Company's inability to contract with additional third-party payors for reimbursement of the Company's products; possible future actions of the U.S. Food and Drug Administration or any other regulatory body or governmental authority; and other risks identified in the Company's most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q, as well as other documents that the Company files with the Securities and Exchange Commission. Investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this release. Tandem undertakes no obligation to update or review any forward-looking statement in this press release because of new information, future events or other factors.
