Year-to-Date Adjusted Net Sales Increase of 16% in Core Portfolio Sales Versus Prior Year Period Reflects Expansion in Surgical Applications

Company to Host Conference Call on November 3, 2021, at 8:30 AM ET

MARIETTA, Ga., November 2, 2021 -- MiMedx Group, Inc. (Nasdaq: MDXG) ("MIMEDX" or the "Company"), an industry leader in utilizing amniotic tissue as a platform for regenerative medicine, today announced the filing of its third quarter 2021 Form 10-Q for the period ended September 30, 2021.

Timothy R. Wright, MIMEDX Chief Executive Officer, commented, "The growth in our core portfolio of tissue and cord products this quarter demonstrates consistent execution on multiple initiatives designed to reinforce and convey the differentiation, clinical evidence and economic value of our brands. We are expanding our presence in surgical applications with our AMNIOFIX® brand and continuing to gain traction with our EPICORD® Expandable product line, which enables customers to address a broader range of lower extremity wounds in a cost-effective way. The success in our base business fuels our investments in clinical operations, medical education, and product development initiatives including portfolio innovation and expansion, ultimately driving better outcomes for patients in need of advanced, evidence-based treatment options."

Mr. Wright continued, "Since announcing the top-line data from our late-stage musculoskeletal clinical trials in mid-September, we have been extensively reviewing the study results to determine the reasons behind the observed differences between patient cohorts in the Knee Osteoarthritis (KOA) trial. As part of our statistical analysis plan, third-party biostatisticians have validated the probability values (p-values) from the Phase 2B KOA study and substantiated both a statistically significant and clinically meaningful outcome in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Total, WOMAC Pain, and WOMAC Function scores for the Pre-Interim Analysis Cohort of 190 patients, with p-values less than 0.05 at three months and less than 0.01 at six months. These positive efficacy signals, while limited to the Pre-Interim Analysis Cohort of 190 patients, provide us with important insights into our approach for our future Phase 3 studies, and we are confident in the therapeutic potential of micronized

dehydrated Human Amnion Chorion Membrane (mdHACM). Our recent scientific publications continue to broaden our understanding of the product's mechanism of action, disease modification potential, and long-term utility as a platform for regenerative medicine. We look forward to reviewing these data and reasons for our continued optimism at our upcoming Investor Day on December 7, 2021, when we also plan to highlight our strategy for achieving sustainable growth across our immediate focus areas of acute and chronic wound care, surgical recovery, and international expansion."

Third Quarter 2021 and Recent Operating Highlights:

•Announced the publication of a peer-reviewed study in the Journal of Wound Care that described the observed impact of advanced treatment using skin substitute products for lower extremity diabetic foot ulcers, including significant reductions in amputations, emergency visits, and hospital readmissions.

•Filed a shelf registration statement with the Securities and Exchange Commission (SEC) that allows the Company to sell up to $350 million of various types of securities for a period of three years; the registration statement was subsequently declared effective by the SEC.

•Reported top-line data from two late-stage musculoskeletal trials in KOA and Plantar Fasciitis.

•Announced plans to host a virtual Investor Day on December 7, 2021.

•Announced the publication of two additional peer-reviewed studies in Osteoarthritis and Cartilage Open and Biomedical Materials Research, Part B. Both studies demonstrate in vitro bioactivity potential of mdHACM in preventing pathological processes underlying Osteoarthritis (OA) and Tendinopathy.

MIMEDX reported net sales for the three months ended September 30, 2021, of $63.1 million, compared to $64.3 million for the three months ended September 30, 2020. Net sales for the three months ended September 30, 2021, includes revenue recognized on the Remaining Contracts (as defined below) of $0.3 million, compared to $1.0 million for the three months ended September 30, 2020.

Adjusted net sales for the three months ended September 30, 2021, which excludes cash collected on the remaining contracts outstanding at the time of the change in the Company's revenue recognition methodology, were $62.8 million compared to $63.3 million for the three months ended September 30, 2020, which included $8.2 million of revenue related to Section 351 products. Excluding sales of Section 351 products, adjusted net sales increased $7.2 million, or 13.1% over the prior year, reflecting growth in surgical applications with the Company's AMNIOFIX sheet portfolio, and in the EPICORD Expandable product line.

MIMEDX has two primary classes of products: (1) Advanced Wound Care, or Section 361, products, consisting of its tissue and cord sheet allograft products, and (2) Section 351 products, consisting of the Company's micronized and particulate products, which prior to the end of the Food and Drug Administration's (FDA) period of Enforcement Discretion (as defined below) were used to treat a variety of patient needs, including both advanced wound care and musculoskeletal applications. Advanced Wound Care is further disaggregated between the Company's Tissue/Other and Cord products. A summary of the Company's revenue, including revenue derived from its Section 351 products, is included in the table below (amounts in thousands):

1.In connection with new guidance provided by the FDA in November 2017, the FDA chose to exercise enforcement discretion with respect to investigational new drug applications and pre-market approval requirements for certain products regulated as Human Cells, Tissues and Cellular and Tissue-Based Products (HCT/Ps) through May 31, 2021 (referred to as the period of Enforcement Discretion).

2."Other" represents cash collections on the Remaining Contracts. Remaining Contracts are those contracts for which performance obligations have been satisfied as of September 30, 2019, but for which the criteria required for revenue recognition had not been met and would not be met until the ultimate collection of cash. For all practicable purposes, the Company is not able to allocate these revenues to different product groups.

Gross profit margin for the three months ended September 30, 2021, was 83.9% compared to 84.0% for the three months ended September 30, 2020.

Selling, general and administrative expenses for the three months ended September 30, 2021, were $46.3 million, compared to $48.0 million for the three months ended September 30, 2020. The decrease in selling, general and administrative expenses during the period was driven by lower professional fees on legal and other matters. These lower fees were partially offset by increases in travel expenses over the prior year period, when the Company implemented travel restrictions in the midst of the COVID-19 pandemic.

Research and development expenses were $4.4 million for the three months ended September 30, 2021, compared to $3.4 million for the three months ended September 30, 2020. The increase reflects higher personnel costs, driven by increases in headcount to support clinical research efforts. While the Company has increased its investments in clinical studies, it did not incur as much research and development expenses as anticipated, due to the delayed timing of clinical trials. Such costs are expected to increase as the Company plans and executes new trials, however the amount and timing of these expenses are partially dependent on whether the clinical trials merit further investment and other factors.

Investigation, restatement and related expenses for the three months ended September 30, 2021, were $3.2 million compared to $12.0 million for the three months ended September 30, 2020. During the three months ended September 30, 2020, MIMEDX incurred expenses toward the advancement of legal fees of certain former officers and directors of the Company. These expenses were not as significant during the same period in 2021. While the Company expects to continue to incur some litigation costs

moving forward, a continued reduction in investigation, restatement and related expenses is anticipated, other than costs related to resolution of the securities class action matter, the amount and timing of which are highly uncertain.

Net loss for the three months ended September 30, 2021, was $2.3 million compared to a net loss of $19.4 million for the three months ended September 30, 2020.

Adjusted EBITDA for the three months ended September 30, 2021, was $6.8 million, or 10.8% of adjusted net sales, compared to $6.9 million, or 11.0% of adjusted net sales, for the three months ended September 30, 2020.

As of September 30, 2021, the Company had $90.6 million of cash and cash equivalents, compared to $95.8 million as of December 31, 2020.

Outlook for 2021

The Company expects that adjusted net sales for fiscal year 2021 will be between $245 million to $255 million, including $16.7 million of Section 351 products sold in the United States for the six months ended June 30, 2021, prior to the end of the period of Enforcement Discretion. Adjusted net sales for fiscal year 2020 were $240.5 million, including $31.8 million of Section 351 products.

Reconciliation of GAAP Net Sales to Adjusted Net Sales and Reconciliation of GAAP Net Income to EBITDA and Adjusted EBITDA

In addition to our GAAP results, we provide certain non-GAAP metrics including Adjusted Net Sales, Earnings Before Interest, Taxes, Depreciation and Amortization ("EBITDA") and Adjusted EBITDA. We believe that the presentation of these measures provides important supplemental information to management and investors regarding our performance. These measurements are not a substitute for GAAP measurements. Company management uses these Non-GAAP measurements as aids in monitoring our ongoing financial performance from quarter-to-quarter and year-to-year on a regular basis and for benchmarking against comparable companies. Adjusted Net Sales is intended to allow one to understand the trend, if any, in sales and to facilitate comparison of sales amounts in periods that used different revenue recognition methods. EBITDA is intended to provide a measure of the Company's operating performance as it eliminates the effects of financing and capital expenditures. EBITDA consists of GAAP net loss excluding: (i) depreciation, (ii) amortization of intangibles, (iii) interest expense, net, (iv) loss on extinguishment of debt, and (v) income tax provision. Adjusted EBITDA is intended to provide a normalized view of EBITDA and our broader business operations that we expect to experience on an ongoing basis by removing certain non-cash items and items that may be irregular, one-time, or non-recurring from EBITDA; most significantly those expenses related to the investigation conducted by the Audit Committee (the "Audit Committee") of the Company's Board of Directors (the "Board") into prior-period matters relating to allegations regarding certain sales and distribution practices at the Company and certain other matters (the "Investigation" or the "Audit Committee Investigation"), the restatement of our consolidated financial statements previously filed in our Annual Report on Form 10-K for the year ended December 31, 2016, as well as selected unaudited condensed consolidated financial data as of and for the years ended December 31, 2015 (Restated) and 2014 (Restated), which reflected adjustments to our previously filed consolidated financial statements as of and for the years ended December 31, 2015 and 2014 (collectively, the "Restatement"), and related litigation. This also includes share-based compensation, which is predominantly settled in shares. This enables us to identify underlying trends in our business that could otherwise be masked by such items. Adjusted EBITDA consists of GAAP net loss excluding: (i) depreciation, (ii) amortization of intangibles, (iii) interest expense, (iv) loss on extinguishment of debt, (v) income tax provision, (vi) costs incurred in connection with Audit Committee Investigation and Restatement, (vii) the effect of the change in revenue recognition on net loss, and (viii) share-based compensation.
