This presentation contains forward-looking statements that involve substantial risks and
uncertainties. “Forward-looking statements,” as that term is defined in the Private Securities Litigation Reform Act of 1995, are statements that are not historical facts and involve a number of risks and uncertainties. Words herein such as
“may,” “will,” “should,” “could,” “would,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “projects,” “predicts,” “intends,” “potential,” “continues,” and similar expressions (as well as other words or expressions referencing
future events, conditions or circumstances) may identify forward-looking statements.The forward-looking statements in this presentation are based upon the Company’s current expectations and beliefs, and involve known and unknown risks,
uncertainties and other factors, which may cause the Company’s actual results, performance and achievements and the timing of certain events to differ materially from the results, performance, achievements or timing discussed, projected,
anticipated or indicated in any forward-looking statements. Such risks, uncertainties and other factors include, among others, the following: failure to obtain, or delays in obtaining, regulatory approvals for ARIKAYCE outside the U.S.,
Europe or Japan, or for the Company’s product candidates in the U.S., Europe, Japan or other markets, including regulatory approval for the Lamira® Nebulizer System and the drug delivery device for TPIP in each market and for each usage;
failure to successfully commercialize ARIKAYCE, the Company's only approved product, in the U.S., Europe or Japan (amikacin liposome inhalation suspension, Liposomal 590 mg Nebuliser Dispersion, and amikacin sulfate inhalation drug product,
respectively), or to maintain U.S., European or Japanese approval for ARIKAYCE; business or economic disruptions due to catastrophes or other events, including natural disasters or public health crises; impact of the COVID-19 pandemic and
efforts to reduce its spread on the Company’s business, employees, including key personnel, patients, partners and suppliers; risk that brensocatib does not prove effective or safe for patients in ongoing and future clinical studies,
including the ASPEN study; risk that TPIP does not prove to be effective or safe for patients in ongoing and future clinical studies; uncertainties in the degree of market acceptance of ARIKAYCE by physicians, patients, third-party payors and
others in the healthcare community; the Company’s inability to obtain full approval of ARIKAYCE from the U.S. Food and Drug Administration, including the risk that the Company will not successfully or in a timely manner complete the study to
validate a PRO tool and the confirmatory post-marketing clinical trial required for full approval of ARIKAYCE; inability of the Company, PARI or the Company’s other third-party manufacturers to comply with regulatory requirements related to
ARIKAYCE or the Lamira® Nebulizer System; the Company’s inability to obtain adequate reimbursement from government or third-party payors for ARIKAYCE or acceptable prices for ARIKAYCE; development of unexpected safety or efficacy concerns
related to ARIKAYCE or the Company’s product candidates; inaccuracies in the Company’s estimates of the size of the potential markets for ARIKAYCE, brensocatib, TPIP or the Company’s other product candidates or in data the Company has used to
identify physicians, expected rates of patient uptake, duration of expected treatment, or expected patient adherence or discontinuation rates; the Company’s inability to create an effective direct sales and marketing infrastructure or to
partner with third parties that offer such an infrastructure for distribution of ARIKAYCE or any of the Company’s product candidates that are approved in the future; failure to obtain regulatory approval to expand ARIKAYCE’s indication to a
broader patient population; risk that the Company’s competitors may obtain orphan drug exclusivity for a product that is essentially the same as a product the Company is developing for a particular indication; failure to successfully predict
the time and cost of development, regulatory approval and commercialization for novel gene therapy products; failure to successfully conduct future clinical trials for ARIKAYCE, brensocatib, TPIP and the Company’s other product candidates due
to the Company’s limited experience in conducting preclinical development activities and clinical trials necessary for regulatory approval and its potential inability to enroll or retain sufficient patients to conduct and complete the trials
or generate data necessary for regulatory approval, among other things; risks that the Company’s clinical studies will be delayed or that serious side effects will be identified during drug development; failure of third parties on which the
Company is dependent to manufacture sufficient quantities of ARIKAYCE or the Company’s product candidates for commercial or clinical needs, to conduct the Company’s clinical trials, or to comply with the Company’s agreements or laws and
regulations that impact the Company’s business or agreements with the Company; failure to comply with the Company’s obligations in the Company’s third party agreements; the Company’s inability to attract and retain key personnel or to
effectively manage the Company’s growth; the Company’s inability to successfully integrate its recent acquisitions and appropriately manage the amount of management’s time and attention devoted to integration activities; risks that the
Company’s acquired technologies, products and product candidates are not commercially successful; the Company’s inability to adapt to its highly competitive and changing environment; risk that the Company is unable to maintain its significant
customers; risk that government healthcare reform materially increases the Company’s costs and damages its financial condition; the Company’s inability to adequately protect its intellectual property rights or prevent disclosure of its trade
secrets and other proprietary information and costs associated with litigation or other proceedings related to such matters; restrictions or other obligations imposed on the Company by agreements related to ARIKAYCE or the Company’s product
candidates, including its license agreements with PARI and AstraZeneca AB, and failure of the Company to comply with its obligations under such agreements; the cost and potential reputational damage resulting from litigation to which the
Company is or may become a party, including product liability claims; risk that the Company’s operations are subject to a material disruption in the event of a cybersecurity attack or issue; business disruptions or expenses related to the
upgrade to the Company’s enterprise resource planning (ERP) system; the Company’s limited experience operating internationally; changes in laws and regulations applicable to the Company’s business, including any pricing reform, and failure to
comply with such laws and regulations; the Company’s history of operating losses, and the possibility that the Company may never achieve or maintain profitability; goodwill impairment charges affecting the Company’s results of operations and
financial condition; inability to repay the Company’s existing indebtedness and uncertainties with respect to the Company’s ability to access future capital; and delays in the execution of plans to build out an additional third-party
manufacturing facility approved by the appropriate regulatory authorities and unexpected expenses associated with those plans.The Company may not actually achieve the results, plans, intentions or expectations indicated by the Company’s

obligation, except as specifically required by law and the rules of the SEC, to publicly update or revise any such statements to reflect any change in expectations or in events, conditions or circumstances on which any such statements may be
