IMPORTANT CAUTIONARY STATEMENT This

presentation contains forward-looking statements. Actual results may differ materially. Investors are cautioned against placing undue reliance on these statements. All statements relating to events or results that may occur in the future are

forward-looking statements, including, without limitation, statements regarding the following: Our expectations regarding market size and opportunities, expected growth in certain markets, and demographic and market trends; there can be no assurance

that the demand for our products will grow. The regulatory pathway for our products, including our existing and planned investigative new drug and investigative device exemption applications and pre-market approval requirements, the timing, design

and success of our clinical trials and pursuit of biologic license applications ("BLAs") and other regulatory approvals for certain products; the process of obtaining regulatory clearances or approvals to market a biological product or

medical device from the FDA or similar regulatory authorities outside of the U.S. is costly and time consuming, and such clearances or approvals may not be granted on a timely basis, or at all. Our expectations regarding our ability to

continue marketing our micronized products and certain other products during and following the end of the period of enforcement discretion announced by the United States Food and Drug Administration ("FDA"); to the extent our products do

not qualify for regulation as human cells, tissues and cellular and tissue-based products solely under Section 361 of the Public Health Service Act ("Section 361"), this could result in removal of the applicable products from the market,

would make the introduction of new tissue products more expensive and would significantly delay the expansion of our tissue product offerings and subject us to additional post-market regulatory requirements. Our expectations regarding future revenue

growth, including product innovations, expansion into additional domestic and international markets, our product pipeline and the potential to increase our product offerings, and future research and development expenses; future revenue growth will

require continued or additional market, regulatory, and payor acceptance of our products, and such acceptance or approvals may not be obtained on a timely basis, or at all. Our expectations regarding growth and investments in our business,

including planned increases in the number of sales representatives and levels of R&D spending; such statements reflect current plans based on current conditions and actual results may vary. Our expectations regarding future CGMP compliance; the

application of CGMP regulations to the manufacture of biologics is complicated and there can be no assurance that we will achieve CGMP compliance on a timely basis, or at all. Our expectations regarding future third party publication of data

regarding our products; the publication of clinical research is time consuming and involves parties not under our control, so there can be no assurance that additional publications will be published on a timely basis, or at all. ongoing and future

effects arising from the COVID-19 pandemic and the Company's plans to adhere to governmental recommendations with respect thereto; the COVID-19 pandemic and governmental and societal responses thereto have adversely affected our business,

results of operations and financial condition, and the continuation of the pandemic or the outbreak of other health epidemics could harm our business, results of operations, and financial condition.

$269.6M Adjusted Net Sales Target Growth 10%+ Tissue and Other Micronized and Particulate Cord The Company expects adjusted net sales will increase 10% or more in 2021 over the prior year, assuming MiMedx is able to sell its micronized, particulate,

and umbilical cord products for the full year. Further, because MiMedx cannot predict the impact of COVID-19 in 2021, the Company's estimate for 2021 adjusted net sales assumes no restrictions on its ability to access hospitals, healthcare provider

facilities and other places where products are sold. Nine months of 2019 Adjusted Net Sales are recognized on a "cash receipts" basis. For a discussion of the revenue transition and the defined terms, refer to Item 8, Notes to the

Consolidated Financial Statements in the MiMedx Group, Inc. Form 10-K for the years ended December 31, 2019 and 2020, and the respective Form 10-Qs for the noted quarterly periods.
