Notes to the Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Nature of Business and Operations

Tactile Systems Technology, Inc. (“we,” “us,” and “our”) is the sole manufacturer and distributor of the Flexitouch® and Entre™ systems, medical devices that help control symptoms of lymphedema, a chronic and progressive medical condition, the Actitouch® system, a medical device used to treat venous leg ulcers and chronic venous insufficiency, and the Airwear wrap, a medical device used for the management of venous insufficiency, venous hypertension, venous ulcerations and lymphedema. Our products are purchased or rented for home use and are recommended by vascular, wound and lymphedema clinics throughout the United States.

We were originally incorporated in Minnesota under the name Tactile Systems Technology, Inc. on January 30, 1995. During 2006, we established a merger corporation and subsequently, on July 21, 2006, merged with and into this merger corporation, resulting in our reincorporation as a Delaware corporation. The resulting corporation assumed the name Tactile Systems Technology, Inc. In September 2013, we began doing business as “Tactile Medical.”

On August 2, 2016, we closed the initial public offering of our common stock, which resulted in the sale of 4,120,000 shares of our common stock at a public offering price of $10.00 per share. We received net proceeds from the initial public offering of approximately $35.4 million, after deducting underwriting discounts and approximately $2.9 million of transaction expenses. In connection with the closing of the initial public offering, all of our outstanding redeemable convertible preferred stock automatically converted to common stock on August 2, 2016. As a result, at August 2, 2016, we did not have any redeemable convertible preferred stock issued or outstanding.

Our business is affected by seasonality. In the first quarter of each year, when most patients have started a new insurance year and have not yet met their annual out-of-pocket payment obligations, we experience substantially reduced demand for our products. We typically experience higher revenue in the third and fourth quarters when patients have met their annual insurance deductibles, thereby reducing their out-of-pocket costs for our products, and because patients desire to exhaust their flexible spending accounts at year end. This seasonality applies only to purchases and rentals of our products by patients covered by commercial insurance and is not relevant to Medicare or the Veterans Administration, as those payers either do not have plans that have declining deductibles over the course of the plan year and/or do not have plans that include patient deductibles for purchases or rentals of our products.

Note 2. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. We have reclassified certain prior year amounts to conform to the current year’s presentation.

The results for the nine months ended September 30, 2019, are not necessarily indicative of results to be expected for the year ending December 31, 2019, or for any other interim period or for any future year. The condensed consolidated interim financial statements should be read in conjunction with the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018.

9

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of Tactile Systems Technology, Inc. and its wholly owned subsidiary, Swelling Solutions, Inc. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and to disclose contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Comprehensive Income

Comprehensive income reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Our comprehensive income represents net income adjusted for unrealized gains and losses on available-for-sale marketable securities and the related taxes.

JOBS Act Accounting Election

Prior to December 31, 2018, we were an “emerging growth company” as defined by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As a result, we were eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. We elected to take advantage of the extended transition period for adopting new or revised accounting standards that have different effective dates for public and private companies until such time as those standards would otherwise apply to private companies. However, as of the last business day of our second fiscal quarter of 2018, the market value of our common stock that was held by non-affiliates exceeded $700.0 million, and as a result, we no longer qualified as an emerging growth company as of December 31, 2018, and are no longer able to take advantage of certain exemptions, including, the extended transition period for adopting new or revised accounting standards and our exemption from providing our auditor’s attestation on our system of internal control over financial reporting, which was included for the first time in our Annual Report on Form 10-K for the year ended December 31, 2018.

Note 3. Summary of Significant Accounting Policies

Significant Accounting Policies

Excluding the adoption of Accounting Standards Codification (“ASC”) 842 – Leases, as described below, there were no material changes in our significant accounting policies during the nine months ended September 30, 2019. See Note 3 – “Summary of Significant Accounting Policies” to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018, for information regarding our significant accounting policies.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, “Leases” (Topic 842) (“ASC 842”), which supersedes the then-existing guidance for lease accounting, “Leases” (Topic 840) (“ASC 840”). ASC 842 requires lessees to recognize a lease liability and a right of use asset for all leases that extend beyond one year. As a result of our change in filing status, we adopted this standard using the modified retrospective transition approach at the adoption date of January 1, 2019. This approach did not require restatement of previous periods. We completed a qualitative and quantitative assessment of our leases from both a lessee and lessor perspective. As part of our process, we elected to utilize certain practical expedients that were provided for transition relief. Accordingly, we did not reassess expired or existing contracts, lease classifications or related initial direct costs as part of our

10

assessment process for either lessee or lessor leases. Additionally, we elected the practical expedient to treat lease and nonlease components of fixed payments due to the lessor as one, and therefore no separate allocation was required on the initial implementation date of January 1, 2019, and thereafter. The adoption of this standard, from a lessee perspective, resulted in us recording right of use (“ROU”) operating lease assets and operating lease liabilities of approximately $3.1 million on the Condensed Consolidated Balance Sheet as of January 1, 2019, with no impact to retained earnings. In addition, we elected as an accounting policy, not to record leases with an initial term of less than 12 months. From a lessor perspective, the application of ASC 842 to our rental revenue, which was recognized as month-to-month, cancelable leases in accordance with ASC 840 through December 31, 2018, resulted in recognizing rental revenue as a sales-type lease under ASC 842 thereafter. Rental sales agreements that commenced prior to December 31, 2018, continue to be recognized as month-to-month, cancelable leases until they are completed, as we elected the practical expedient to not reassess the lease classification for leases in existence upon adoption. As such, rental agreements commencing after January 1, 2019, were recorded as sales-type leases with the associated revenue and cost of revenue recognized on the lease commencement date and a corresponding net investment in leases on the Condensed Consolidated Balance Sheet. (See Note 10 – “Commitments and Contingencies” and Note 12 – “Revenue” for additional information and required disclosures.)

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments — Credit Losses, to require the measurement of expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable forecasts. The ASU will be effective for us for interim and annual periods beginning January 1, 2020. Therefore, we plan to further evaluate the anticipated impact of the adoption of this ASU on the condensed consolidated financial statements in future periods.

In July 2018, the FASB issued ASU No. 2018-07, Improvements to Non-employee Share-Based Payment Accounting (“ASU 2018-07”), which expands the scope of ASC 718 – Stock Based Compensation to include share-based payment transactions for acquiring goods and services from non-employees. The ASU was effective for us beginning January 1, 2019, including interim periods within the fiscal year. We adopted ASU 2018-07 for the quarter ended March 31, 2019, and it did not have a material impact on the condensed consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (“ASU 2018-15”), which aligns the accounting for implementation costs incurred in a cloud computing arrangement that is a service contract with the guidance on capitalizing costs associated with developing or obtaining internal-use software. We early adopted this ASU effective January 1, 2019, and it did not have a material impact on the condensed consolidated financial statements.

Note 9. Credit Agreement

On August 3, 2018, we entered into a credit agreement with Wells Fargo Bank, National Association, which was amended by a First Amendment dated February 12, 2019, a Waiver and Second Amendment dated March 25, 2019, and a Third Amendment dated August 2, 2019 (collectively, the “Credit Agreement”), which expires on August 3, 2021.

The Credit Agreement provides for a $10.0 million revolving credit facility. Subject to satisfaction of certain conditions, we may increase the amount of the revolving loans available under the Credit Agreement and/or add one or more term loan facilities in an amount not to exceed an incremental $25.0 million in the aggregate, such that the total aggregate principal amount of loans available under the Credit Agreement (including under the revolving credit facility) does not exceed $35.0 million. As of September 30, 2019, and the date on which we filed this report, we did not have any outstanding borrowings under the Credit Agreement.

Our obligations under the Credit Agreement are secured by a security interest in substantially all of our and our subsidiaries’ assets and are also guaranteed by our subsidiaries. The Credit Agreement contains a number of restrictions and covenants, including that we maintain compliance with a maximum leverage ratio and a minimum liquidity covenant. As of September 30, 2019, we were in compliance with all financial covenants under the Credit Agreement.

Note 10. Commitments and Contingencies

Lease Obligations

We lease property and equipment under operating leases, typically with terms greater than 12 months, and determine if an arrangement contains a lease at inception. In general, an arrangement contains a lease if there is an identified asset and we have the right to direct the use of and obtain substantially all of the economic benefit from the use of the identified asset. We record an operating lease liability at the present value of lease payments over the lease term on the commencement date. The related ROU operating lease asset reflects rental escalation clauses, as well as renewal options and/or termination options. The exercise of lease renewal and/or termination options are at our discretion and are included in the determination of the lease term and lease payment obligations when it is deemed reasonably certain that the option will be exercised. When available, we use the rate implicit in the lease to discount lease payments to present value; however, certain leases do not provide a readily determinable implicit rate. Therefore, we must estimate our incremental borrowing rate to discount the lease payments based on information available at lease commencement.

We classify our leases as buildings, vehicles or computer and office equipment and do not separate lease and nonlease components of contracts for any of the aforementioned classifications. In accordance with

14

applicable guidance, we do not record leases with terms that are less than one year on the Condensed Consolidated Balance Sheet.

None of our lease agreements contain material restrictive covenants or residual value guarantees.

Buildings

We lease certain office and warehouse space at various locations in the United States where we provide services. These leases are typically greater than one year with fixed, escalating rents over the noncancelable terms and, therefore, ROU operating lease assets and operating lease liabilities are recorded on the Condensed Consolidated Balance Sheet, with rent expense to be recognized on a straight-line basis over the term of the lease. The remaining lease terms vary from approximately one to ten years as of September 30, 2019.

In March 2008, we entered into a noncancelable operating lease agreement for building space for our previous corporate headquarters that provides for monthly rent, real estate taxes and operating expenses that was subsequently extended to July 31, 2021. This space is included in our ROU operating lease assets and operating lease liabilities. We are in the process of negotiating a buy-out of the lease for these premises due to our move in September to our new headquarters.

We entered into a lease (“initial lease”) in October 2018 for approximately 80,000 square feet of office space for our new corporate headquarters in Minneapolis, Minnesota. In December 2018, we amended the initial lease to add 29,000 square feet of additional office space, which is accounted for as a separate lease (“second lease”) in accordance with ASC 842. The initial and second leases expire in February 2030. The portion of the space under the initial lease was placed in service in September 2019. This portion was recognized as an operating lease and included in the ROU operating lease assets and operating lease liabilities on the Condensed Consolidated Balance Sheet.  The portion of the space covered under the second lease is expected to be occupied and commence in the second half of 2020.

Vehicles

We lease vehicles for certain members of our field sales organization under a vehicle fleet program whereby the initial, noncancelable lease is for a term of 367 days, thus more than one year. Subsequent to the initial term, the lease becomes a month-to-month, cancelable lease. As of September 30, 2019, we had approximately 75 vehicles with agreements within the initial, noncancelable lease term that are recorded as ROU operating lease assets and operating lease liabilities. In addition to monthly rental fees specific to the vehicle, there are fixed monthly nonlease components that have been included in the ROU operating lease assets and operating lease liabilities. The nonlease components are not significant.

Computer and Office Equipment

We also have operating lease agreements for certain computer and office equipment. The remaining lease terms at the ASC 842 adoption date of January 1, 2019, ranged from less than one year to approximately five years with fixed monthly payments that are included in the ROU operating lease assets and operating lease liabilities. The leases provide an option to purchase the related equipment at fair market value at the end of the lease. The lease will automatically renew as a month-to-month rental at the end of the lease if the equipment is not purchased or returned.
