Third Quarter 2022 Summary:

Third Quarter 2022 Highlights:

"We are excited to deliver total revenue performance that exceeded our expectations for the third quarter," said Dan Reuvers, President and Chief Executive Officer of Tactile Medical. "Sales of our airway clearance products benefited from strong demand by our DME channel partners, as their sales reps continued to adopt our technology and identify patients in need of treatment among their existing customers. In our lymphedema business, we were pleased to see improvement in patient volumes at the clinics we serve, along with a positive initial response following the full market release of our ComfortEase garments. Importantly, in addition to our strong sales performance, we also delivered significant improvements in our profitability, increasing our gross, operating and adjusted EBITDA margins compared to the prior year quarter."

Mr. Reuvers continued, "We are raising our guidance today to reflect our stronger-than-anticipated third quarter results. We remain focused on continued execution with respect to our four objectives for the second half of 2022: improving the productivity of our recently expanded salesforce, facilitating the introduction of our new products, supporting our DME channel partners and improving profitability. By continuing to execute on these objectives, we aim to position Tactile Medical for sustainable growth and improving profitability."

Total revenue in the third quarter of 2022 increased $12.8 million, or 24%, to $65.3 million, compared to $52.5 million in the third quarter of 2021. The increase in total revenue was attributable to an increase of $10.2 million in sales of the airway clearance product line, which includes the AffloVest product acquired on September 8, 2021, and an increase of $2.6 million, or 5%, in sales and rentals of the lymphedema product line compared to the third quarter of 2021.

Gross profit in the third quarter of 2022 increased $9.8 million, or 27%, to $46.8 million, compared to $37.0 million in the third quarter of 2021. Gross margin was 71.7% of revenue, compared to 70.4% of revenue in the third quarter of 2021. Non-GAAP gross margin was 72.2% of revenue, compared to 71.8% of revenue in the third quarter of 2021.

Other expense was $0.7 million in the third quarter of 2022, compared to $0.1 million in the third quarter of 2021. The change in other expense was primarily due to an increase in interest expense.

Income tax benefit was $77,000 in the third quarter of 2022, compared to an expense of $1.9 million in the third quarter of 2021.

Use of Non-GAAP Financial Measures

This press release includes the non-GAAP financial measures of Adjusted EBITDA, non-GAAP gross margin, non-GAAP operating income (loss), and non-GAAP net income (loss), which differ from financial measures calculated in accordance with U.S. generally accepted accounting principles ("GAAP").

Adjusted EBITDA in this release represents net income or loss, plus interest expense, net, or less interest income, net, less income tax benefit or plus income tax expense, plus depreciation and amortization, plus stock-based compensation expense, plus impairment charges and inventory write-offs, plus acquisition costs, plus litigation defense costs, plus or minus the change in fair value of earn-out, and plus executive transition costs. Non-GAAP gross margin in this release represents gross margin plus non-cash intangible amortization expense, inventory write-offs, and inventory purchase price adjustments. Non-GAAP operating income (loss) in this release represents operating income (loss) adjusted for non-cash intangible amortization expense, inventory write-offs, inventory purchase price adjustments, acquisition costs and expenses, change in fair value of earn-out, litigation defense costs and executive transition expenses. Non-GAAP net income (loss) represents net income (loss) adjusted for non-cash intangible amortization expense, inventory write-offs, inventory purchase price adjustments, acquisition costs and expenses, change in fair value of earn-out, litigation defense costs and executive transition expenses and adjusted for the income tax effect on reconciling items. Reconciliations of these non-GAAP financial measures to their most directly comparable GAAP measures are included in this press release.

These non-GAAP financial measures are presented because the Company believes they are useful indicators of its operating performance. Management uses these measures principally as measures

of the Company's operating performance and for planning purposes, including the preparation of the Company's annual operating plan and financial projections. The Company believes these measures are useful to investors as supplemental information and because they are frequently used by analysts, investors and other interested parties to evaluate companies in its industry. The Company also believes these non-GAAP financial measures are useful to its management and investors as a measure of comparative operating performance from period to period. In addition, Adjusted EBITDA is used as a performance metric in the Company's compensation program.

The non-GAAP financial measures presented in this release should not be considered as an alternative to, or superior to, their respective GAAP financial measures, as measures of financial performance or cash flows from operations as a measure of liquidity, or any other performance measure derived in accordance with GAAP, and they should not be construed to imply that the Company's future results will be unaffected by unusual or non-recurring items. In addition, Adjusted EBITDA is not intended to be a measure of free cash flow for management's discretionary use, as it does not reflect certain cash requirements such as tax payments, debt service requirements, capital expenditures and certain other cash costs that may recur in the future. Adjusted EBITDA contains certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital needs and cash costs to replace assets being depreciated and amortized. In evaluating non-GAAP financial measures, you should be aware that in the future the Company may incur expenses that are the same as or similar to some of the adjustments in this presentation. The Company's presentation of non-GAAP financial measures should not be construed to imply that its future results will be unaffected by any such adjustments. Management compensates for these limitations by primarily relying on the Company's GAAP results in addition to using non-GAAP financial measures on a supplemental basis. The Company's definition of these non-GAAP financial measures is not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation.
