[[Image Removed: dxcm-20211231_g7.jpg]] Future Developments
Product Development: We plan to develop future generations of technologies that are focused on improved performance and convenience and that will enable intelligent insulin administration. Over the longer term, we plan to continue to develop and improve networked platforms with open architecture, connectivity and transmitters capable of communicating with other devices. We also intend to expand our efforts to accumulate CGM patient data and metrics and apply predictive modeling and machine learning to generate interactive CGM insights that can inform patient behavior. Partnerships: We also continue to pursue and support development partnerships with insulin pump companies and companies or institutions developing insulin delivery systems, including automated insulin delivery systems. New Opportunities: We are also exploring how to extend our offerings to other opportunities, including for people with Type 2 diabetes that are non-insulin using, people with pre-diabetes, people who are obese, people who are pregnant, and people in the hospital setting. Eventually, we may apply our technological expertise to products beyond glucose monitoring. 70

These conditions continue to create various financial impacts to our operations by necessitating precautions for our personnel to operate safely both in person as well as remotely. Costs incurred include items like incremental payroll costs, consulting support, IT infrastructure and facilities-related costs. As the result of the COVID-19 pandemic, we made Dexcom CGM systems available for use in hospital settings and other healthcare facilities to assist frontline workers. The extent of the impact of the COVID-19 pandemic on our operational and financial performance will depend on certain developments, including the duration and spread of the outbreak, impact on our customers and our sales cycles, employee or industry events, and effect on our vendors, all of which are uncertain and cannot be predicted. The COVID-19 pandemic and its adverse effects have become more prevalent in the locations where we, our customers, suppliers or third-party business partners conduct business and as a result, we have experienced moderate disruptions in our global operations. We have experienced and may experience constrained supply or curtailed customer demand, including due to customer loss of private health insurance coverage for our products, that could materially adversely impact our business, results of operations and overall financial performance in future periods. We currently utilize third parties to, among other things, manufacture components and materials for our devices, and to provide services such as sterilization services and we purchase these materials and services from numerous suppliers worldwide. The COVID-19 pandemic has and may continue to have an adverse impact on our manufacturing and distribution capabilities. Disruptions relating to the COVID-19 pandemic, including shelter-in-place orders in theU.S. and other countries, could prevent employees, suppliers, distributors, and others from accessing manufacturing facilities and from transporting our products or the components required to manufacture our products. For example, we have experienced some supply chain disruption due to the global restrictions resulting from the COVID-19 pandemic in the manufacturing of our next-generation CGM product. Further, worldwide supply chain disruption relating to the COVID-19 pandemic has resulted in product shortages that has and may continue to impact our ability to manufacture our devices. As of the filing date of this Annual Report, the extent to which COVID-19 may impact our financial condition or results of operations or guidance is uncertain. The effect of the COVID-19 pandemic will not be fully reflected in our results of operations and overall financial performance until future periods. See "Risk Factors" in Part I, Item 1A of this Annual Report for further discussion of the possible impact of the COVID-19 pandemic on our business. 71
-------------------------------------------------------------------------------- Critical Accounting Estimates The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which we have prepared in accordance withU.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements as well as the reported revenue and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Variability reflected in the sensitivity analysis presented below is based on our recent historical experience. Actual results may differ from these estimates under different assumptions or conditions. While our significant accounting policies are described in Note 1 to the consolidated financial statements in Part II, Item 8 of this Annual Report, we believe that the following accounting estimates are most critical to a full understanding and evaluation of our reported financial results. Members of our senior management have discussed the development and selection of these critical accounting estimates and their disclosure in this Annual Report with the Audit Committee of our Board of Directors. Pharmacy Rebates We estimate provisions for pharmacy rebates based on contractual arrangements, estimates of products sold subject to rebate, known events or trends and channel inventory data. Estimates associated with rebates on products sold through our distributors under pharmacy benefits are the most significant component of our variable consideration estimates and most at risk for material adjustment because of the time delay between the recording of the accrual estimate and its ultimate settlement, an interval that generally ranges from 30 to 90 days, but can last up to one year. Due to this time lag, in any given period, our adjustments to reflect actual amounts can incorporate changes of estimates related to prior periods. Historically, adjustments to these estimates to reflect actual results or updated expectations, have not been material to our overall business and generally have been less than 1% of revenue. An increase or decrease of 1% in our estimate of products sold subject to rebate during 2021, holding all other assumptions constant, would increase or decrease revenue by approximately$11.5 million . For more information, see Revenue Recognition in Note 1 to the consolidated financial statements in Part II, Item 8 of this Annual Report. Excess and Obsolete Inventory We assess the value of our inventory on a quarterly basis and write down those inventories based on quality control testing data, obsolescence, or in excess of our forecasted demand to the lower of their cost or net realizable value. Our estimates of forecasted demand are based upon our analysis and assumptions including, but not limited to, expected product lifecycles, product development plans and historical usage by product. If actual market conditions are less favorable than our forecasts, or actual demand from our customers is lower than our estimates, we may be required to record additional inventory write-downs. If actual market conditions are more favorable than anticipated, inventory previously written down may be sold, resulting in lower cost of sales and higher income from operations than expected in that period. Income Taxes We estimate our income taxes based on the various jurisdictions where we conduct business. Significant judgment is required in determining our worldwide income tax provision. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations and the potential for future adjustment of our uncertain tax positions by the Internal Revenue Service or other taxing jurisdictions. While we believe we have appropriate support for the positions taken on our tax returns, we regularly assess the potential outcomes of examinations by tax authorities in determining the adequacy of our provision for income taxes. We continually assess the likelihood and amount of potential adjustments and adjust the income tax provision, income taxes payable, and deferred taxes in the period in which the facts that give rise to a revision become known. We use the asset and liability approach to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities as described in Note 1 to the consolidated financial statements in Part II, Item 8 of this Annual Report. Significant judgment is required to evaluate the need for a valuation allowance against deferred tax assets. A valuation allowance is established when it is more likely than not that some or all of the deferred tax assets will not be realized. Realization of deferred tax assets is dependent upon future earnings in applicable tax jurisdictions. We maintain a valuation allowance on ourCalifornia research and 72 -------------------------------------------------------------------------------- development tax credits, foreign tax credits, and certain foreign intangible assets, as it is more likely than not that those deferred tax assets will not be realized. We recognize and measure benefits for uncertain tax positions using a two-step approach as described in Note 1 to the consolidated financial statements in Part II, Item 8 of this Annual Report. Significant judgment is required to evaluate uncertain tax positions and is based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in material increases or decreases in our income tax expense in the period in which we make the change, which could have a material impact on our effective tax rate and operating results. Loss Contingencies We are subject to certain legal proceedings, as well as demands, claims and threatened litigation that arise in the normal course of our business. We review the status of each significant matter quarterly and assess our potential financial exposure. Significant judgment is required in the determination of whether a potential loss is probable, reasonably possible, or remote as well as in the determination of whether a potential exposure is reasonably estimable. We base our judgments on the best information available at the time. As additional information becomes available, we reassess the potential liability related to our pending claims and litigation and may revise our estimates. Any revision of our estimates of potential liability could have a material impact on our financial position and operating results. 73 --------------------------------------------------------------------------------

Revenue
We expect that revenue we generate from the sales of our products will fluctuate from quarter to quarter. We typically experience seasonality, with lower sales in the first quarter of each year compared to the immediately preceding fourth quarter. This seasonal sales pattern relates toU.S. annual insurance deductible resets and unfunded flexible spending accounts. Cost of Sales Cost of sales includes direct labor and materials costs related to each product sold or produced, including assembly, test labor and scrap, as well as factory overhead supporting our manufacturing operations. Factory overhead includes facilities, material procurement and control, manufacturing engineering, quality assurance, supervision and management. These costs are primarily salary, fringe benefits, share-based compensation, facility expense, supplies and purchased services. All of our manufacturing costs are included in cost of sales. Research and Development Our research and development expenses primarily consist of engineering and research expenses related to our continuous glucose monitoring technology, clinical trials, regulatory expenses, quality assurance programs, materials and products for clinical trials. Research and development expenses are primarily related to employee compensation, including salary, fringe benefits, share-based compensation, and temporary employee expenses. We also incur significant expenses to operate our clinical trials including clinical site reimbursement, clinical trial product and associated travel expenses. Our research and development expenses also include fees for design services, contractors and development materials. Selling, General and Administrative Our selling, general and administrative expenses primarily consist of salary, fringe benefits and share-based compensation for our executive, financial, sales, marketing, information technology and administrative functions. Other significant expenses include commissions, marketing and advertising, IT software license costs, insurance, professional fees for our outside legal counsel and independent auditors, litigation expenses, patent application expenses and consulting expenses. Twelve Months EndedDecember 31, 2021 Compared to Twelve Months EndedDecember 31, 2020 The revenue increase was primarily driven by increased sales volume of our disposable sensors due to the continued growth of our worldwide customer base, partially offset by mix shift and price associated with the evolution of our channel strategy. Revenue Disposable sensor and other revenue comprised approximately 84% of total revenue and Reusable Hardware revenue comprised approximately 16% of total revenue for the twelve months endedDecember 31, 2021 . Disposable sensor and other revenue comprised approximately 81% of total revenue and Reusable Hardware revenue comprised approximately 19% of total revenue for the twelve months endedDecember 31, 2020 . Cost of sales increased primarily due to an increase in sales volume. Cost of Sales & Gross The increase in gross profit and gross profit margin in 2021 compared Profit to 2020 were primarily driven by increased revenue and cost savings associated with incremental improvements to product design, manufacturing efficiencies and economies of scale. Research and development expense increased primarily due to$62.7 million in additional third party and
consulting fees primarily related
to software development for new products and significant enhancements,$49.1 million in additional salaries, bonuses, and payroll-related Research and costs primarily due to higher headcount, and$13.2 million in Development Expense additional clinical trials costs related to pivotal trials. We continue to believe that focused investments in research and development are critical to our future growth and competitive position in the marketplace, and to the development of new and updated products and services that are central to our core business strategy. 76

Development Fee the 2018 collaboration and license
agreement with Verily. See Note 2
"Development and Other Agreements" to the consolidated financial statements in Part II, Item 8 of this Annual Report for more information. Selling, general and administrative
expense increased primarily due to
$84.0 million in additional advertising and marketing costs due to an increase in worldwide marketing campaigns,$60.5 million in additional Selling, General and salaries, bonuses, and payroll-related costs primarily due to higher Administrative Expense headcount primarily related to an expansion in our sales force,$16.3 million in additional legal expense related to litigation,$7.4 million of investments in customer
experience, partially offset by
$12.9 million in lower third party service provider fees due to a change in our channel strategy. The loss on extinguishment of debt of$1.5 million and$5.9 million is primarily related to the conversions
and/or repurchases of our senior

financial statements in Part II, Item 8 of
this Annual Report for more
information about these transactions. Income from Equity Income from equity investments of$11.6
million for the twelve months
Investments endedDecember 31, 2021 consisted solely of realized gains from the sale of an equity investment. Interest expense is comprised primarily of costs related to our senior Interest Expense convertible notes. Interest expense
increased primarily due to the May
2020 issuance of our 2025 Notes. Interest and other income (expense), net,
consists primarily of Interest and Other Income interest income on our short-term marketable securities portfolio and
(Expense), Net foreign currency transaction gains and
losses due to the effects of
foreign currency fluctuations. The
decrease in interest income was
primarily related to a decline in market interest rates. We recorded pre-tax income for the twelve months endedDecember 31, 2021 andDecember 31, 2020 . The income tax expense we recorded for 2021 is primarily attributable to income tax
expense from normal, recurring
Income Tax Expense operations offset by excess tax benefits recognized for employee (Benefit) share-based compensation, generation of research and development tax credits, and a one-time tax benefit
related to tax law changes. The
income tax benefit we recorded for 2020 is primarily attributable to the release of our valuation allowance on specificU.S. and foreign deferred tax assets. 77
--------------------------------------------------------------------------------
Liquidity and Capital Resources Overview, Capital Resources, and Capital Requirements Our principal sources of liquidity are our existing cash, cash equivalents and marketable securities, cash generated from operations, proceeds from our senior convertible notes issuances, and access to our Credit Facility. Our primary uses of cash have been for research and development programs, selling and marketing activities, capital expenditures, acquisitions of businesses, and debt service costs. We expect that cash provided by our operations may fluctuate in future periods as a result of a number of factors, including fluctuations in our operating results, working capital requirements, and capital deployment decisions. We have historically invested our cash primarily inU.S. dollar-denominated, investment grade, highly liquid obligations ofU.S. government agencies, commercial paper, corporate debt, and money market funds. Certain of these investments are subject to general credit, liquidity, and other market risks. The general condition of the financial markets and the economy may increase those risks and may affect the value and liquidity of investments and restrict our ability to access the capital markets. Our future capital requirements will depend on many factors, including but not limited to: The evolution of the Our ability to efficiently The success of our research international expansion of our scale our operations to meet and development efforts; business and the revenue demand for our current
and any
generated by sales of our future products; approved products and other future products; The expenses we incur in The costs, timing and risks of The costs of filing, manufacturing, developing, delays of additional regulatory prosecuting, defending and selling and marketing our approvals; enforcing any patent claims products; and other intellectual property rights; The quality levels of our The emergence of competing or The terms and timing of any products and services; complementary technological collaborative, licensing and developments; other arrangements that we may establish; The third-party reimbursement of The rate of progress and cost The acquisition of our products for our customers; of our clinical trials and businesses, products and other development activities; technologies and our ability to integrate and manage any acquired businesses, products and technologies. We expect that existing cash and short-term investments and cash flows from our future operations will generally be sufficient to fund our ongoing core business. As current borrowing sources become due, we may be required to access the capital markets for additional funding. As we assess inorganic growth strategies, we may need to supplement our internally generated cash flow with outside sources. In the event that we are required to access the debt market, we believe that we will be able to secure reasonable borrowing rates. As part of our liquidity strategy, we will continue to monitor our current level of earnings and cash flow generation as well as our ability to access the market in light of those earning levels. A substantial portion of our operations are located inthe United States , and the majority of our sales since inception have been made inU.S. dollars. Accordingly, our assessment is that we have no material net exposure to foreign currency exchange rate fluctuations at this time. However, as our business in markets outside ofthe United States continues to increase, we will be exposed to foreign currency exchange risk related to our foreign operations. Fluctuations in the rate of exchange between theU.S. dollar and foreign currencies, primarily the Australian Dollar, the British Pound, the Canadian Dollar, the Euro and the Malaysian Ringgit, could adversely affect our financial results, including our revenues, revenue growth rates, gross margins, income and losses as well as assets and liabilities. We currently engage in hedging transactions to reduce foreign currency risks. We will continue to monitor and manage our financial exposures due to exchange rate fluctuations as an integral part of our overall risk management program. 78 -------------------------------------------------------------------------------- Main Sources of Liquidity Cash, cash equivalents and short-term marketable securities Our cash, cash equivalents and short-term marketable securities totaled$2.73 billion as ofDecember 31, 2021 . None of those funds were restricted and approximately 95% of those funds were located inthe United States . Cash flow from Operations For the twelve months endedDecember 31, 2021 , we had positive cash inflows of$442.5 million from operating activities. We anticipate that we will continue to generate positive cash inflows for the foreseeable future. Senior Convertible Notes We received net proceeds of$836.6 million inNovember 2018 from the 2023 Notes offering and net proceeds of$1.19 billion inMay 2020 from the 2025 Notes offering. We used$100.0 million of the net proceeds from the offering of the 2023 Notes to repurchase a portion of our common stock in 2018. We used$282.6 million of the net proceeds from the offering of the 2025 Notes to repurchase a portion of our senior convertible notes due 2022, or 2022 Notes. We intend to use the remainder of the net proceeds from the 2023 Notes and 2025 Notes offerings for general corporate purposes and capital expenditures, including working capital needs. We may also use the net proceeds to expand our current business through in-licensing or acquisitions of, or investments in, other businesses, products or technologies; however, we do not have any significant commitments with respect to any such acquisitions or investments at this time. The 2023 Note Hedge is expected to reduce the potential equity dilution upon any conversion of the 2023 Notes and/or offset any cash payments we are required to make in excess of the principal amount of converted 2023 Notes. See Note 5 "Debt" to the consolidated financial statements in Part II, Item 8 of this Annual Report for conversion activity related to the 2023 Notes and shares received as the result of exercising a portion of the 2023 Note Hedge as well as for more information about the 2023 Notes and the 2025 Notes, the 2023 Note Hedge, and the 2023 Warrants. Revolving Credit Agreement As ofDecember 31, 2021 , we had no outstanding borrowings,$7.3 million in outstanding letters of credit, and a total available balance of$192.7 million under the Amended Credit Agreement. We monitor counterparty risk associated with the institutional lenders that are providing the Credit Facility. We currently believe that the Credit Facility will be available to us should we choose to borrow under it. Revolving loans will be available for general corporate purposes, including working capital and capital expenditures. See Note 5 "Debt" to the consolidated financial statements in Part II, Item 8 of this Annual Report for more details on the Revolving Credit Agreement. Short-term Liquidity Requirements Our short-term liquidity requirements primarily consist of regular operating costs, interest payments related to our senior convertible notes, capital expenditures for the development of our manufacturing facilities and office spaces, and short-term material cash requirements as described below. As ofDecember 31, 2021 , we had a working capital ratio of 5.11 and a quick ratio of 4.50, which indicates that our current assets are more than enough to cover our short-term liabilities. We expect to have significant capital expenditures for the next year to drive our strategic initiative of building out our manufacturing facility and equipment inMalaysia and the capacity scale-up inMesa, Arizona . We believe that our cash, cash equivalents, and marketable securities balances, projected cash contributions from our commercial operations, and borrowings under our Credit Facility will be sufficient to meet our anticipated seasonal working capital needs, all capital expenditure requirements, material cash requirements as described below, and other liquidity requirements associated with our operations for at least the next 12 months. Long-term Liquidity Requirements Our long-term liquidity requirements primarily consist of interest and principal payments related to our senior convertible notes, capital expenditures for the development of our manufacturing facilities and office spaces, and long-term material cash requirements as described below. As ofDecember 31, 2021 , we had a debt-to-assets ratio of 0.35, which indicates that our total assets are more than enough to cover our short-term and long-term debts. As demand grows for our products, we will continue to expand global operations to meet demand through investments in manufacturing and operations. We expect to meet our long-term liquidity requirements from our main sources of liquidity as described above to support our future operations, capital expenditures, acquisitions, and other liquidity requirements associated with our operations beyond the next 12 months. As ofDecember 31, 2021 , we have outstanding senior convertible notes that will mature inDecember 2023 for the 2023 Notes andNovember 2025 for the 2025 Notes. However, the outstanding principal of our senior convertible notes could be converted into cash and/or shares of our common stock prior to maturity once certain conditions are met. See Note 5 "Debt" to 79 -------------------------------------------------------------------------------- the consolidated financial statements in Part II, Item 8 of this Annual Report for information on conversion rights prior to maturity. Material Cash Requirements From time to time in the ordinary course of business, we enter into a variety of purchase arrangements including but not limited to, purchase arrangements related to capital expenditures, components used in manufacturing forthe United States andMalaysia , and research and development activities. See Purchase Commitments in Note 6 to the consolidated financial statements in Part II, Item 8 of this Annual Report for more information. We issued senior convertible notes inNovember 2018 andMay 2020 . The obligations presented above include both principal and interest for these notes. Although these notes mature in 2023 and 2025, they may be converted into cash and shares of our common stock prior to maturity if certain conditions are met. Any conversion prior to maturity can result in repayment of the principal amounts sooner than the scheduled repayment as indicated in the table. As ofDecember 31, 2021 , we had outstanding letters of credit of$7.3 million for which we cannot forecast with certainty the amount and timing of repayments. See Note 5 "Debt" to the consolidated financial statements in Part II, Item 8 of this Annual Report for further discussion of the terms of our senior convertible notes. We are party to various leasing arrangements, primarily for office, manufacturing and warehouse space that expire at various times throughDecember 2030 , excluding any renewal options. We also have a land lease inPenang, Malaysia for the build-out of our international manufacturing facility lease that expires in 2080. We anticipate incurring significant expenditures related to the build-out of theMalaysia manufacturing facility and equipment in the next 24 months. See Leases in Note 6 to the consolidated financial statements in Part II, Item 8 of this Annual Report for more information. Under our Restated Collaboration Agreement with Verily, upon the first regulatory approval of our next generation G7 CGM system, a regulatory approval milestone payment equivalent to 736,377 shares of our common stock, calculated based on the$100.0 million initial milestone amount divided by the volume-weighted average trading price during the 15 consecutive days ending on the date of the Restated Collaboration Agreement, will become payable. Additional sales-based milestone payments equivalent to 1,288,660 shares of our common stock, calculated based on the$175.0 million initial milestone amount divided by the volume-weighted average trading price during the 15 consecutive days ending on the date of the Restated Collaboration Agreement, may become due and payable by us upon achievement of certain sales-based milestones. All milestones may be paid in cash or shares of our common stock, at our election. If we elect to make these milestone payments in cash, any such cash payment would be equal to the number of shares that would otherwise be issued for the given milestone payment multiplied by the value of our stock on the date the relevant milestone is achieved, adjusted for stock splits, dividends, and the like. We intend to pay these milestones in shares of our common stock and as such we do not expect to have a material cash requirement for this agreement. See Note 2 "Development and Other Agreements" to the consolidated financial statements in Part II, Item 8 of this Annual Report for further discussion of the Collaboration Agreement with Verily. 80 -------------------------------------------------------------------------------- Cash Flows
