"I am pleased with the solid execution by our team in an uncertain environment, delivering a strong quarter of profit and positive cash flow. We have seen accelerating interest in our industry leading Genesis Network mesh control and monitoring technology since its launch last quarter, and we continue to invest in other exciting new technologies through our R&D program. Our teams have executed the previously announced continuous improvement and restructuring programs, resulting in gross profit margin expansion of 310 basis points to 46.4% and Adjusted EBITDA margins of 23.3%--the highest in any quarter since December 2017. We expect our customer's capital spending levels to remain depressed in the near term, but have observed positive trends in maintenance spending in recent months. In the long-term, we will drive value creation for our shareholders by delivering industry leading technology and safety while continuing to manage our overall cost structure for the level of incoming business," said Bruce Thames, Thermon's President and Chief Executive Officer.

During Q3 2021, the Company generated revenue of $79.6 million versus $100.5 million in Q3 2020, a decrease of $20.9 million, or 21%. During Q3 2021, new facility construction (or "Greenfield") and facility maintenance, repair and operations and upgrade or expansion (or "MRO/UE") activity from our legacy heat tracing business accounted for 38% and 62% of revenue, respectively, which compares to 38% and 62%, respectively, in Q3 2020. Gross margin during Q3 2021 was 46.4%, as compared to 43.3% in Q3 2020.

Q3 2021 total orders were $71.0 million versus $99.0 million in Q3 2020, a decrease of $28.0 million, or 28%. Q3 2021 backlog of $110.1 million represents a $7.6 million increase, or 7%, as compared to Q3 2020 backlog of $102.5 million.

Q3 2021 net income attributable to Thermon and EPS were $6.2 million and $0.18, respectively, compared to net income and EPS of $6.5 million and $0.20, respectively, in Q3 2020. After taking into account the impact of restructuring, the benefit from the Canadian Emergency Wage Subsidy (the "CEWS") and intangible amortization related to prior acquisition activities (see table, Reconciliation of Net Income (Loss) Attributable to Thermon to Adjusted Net Income (Loss) and Adjusted EPS), the Company generated an Adjusted Net Income in Q3 2021 of $10.0 million and Adjusted EPS of $0.30 compared to $9.5 million and $0.28, respectively, in Q3 2020.

Adjusted EBITDA was $18.5 million in Q3 2021 as compared to $20.9 million in Q3 2020, a decrease of $2.4 million, or 11% (see table, Reconciliation of Net Income (Loss) Attributable to Thermon to Adjusted EBITDA).

During the first nine months of the fiscal year ending March 31, 2021 ("YTD 2021"), the Company generated revenue of $202.9 million compared to $295.1 million in the first nine months of the fiscal year ended March 31, 2020 ("YTD 2020"), a decrease of $92.2 million, or 31%.

YTD 2021 orders were $207.4 million compared to $274.9 million in YTD 2020, a decrease of $67.5 million, or 25%.

YTD 2021 Net Income (Loss) attributable to Thermon and EPS were $1.9 million and $0.06, respectively, compared to $14.9 million and $0.45 in YTD 2020. After taking into account the impact of restructuring, the benefit from the CEWS and intangible amortization (see table, Reconciliation of Net Income (Loss) Attributable to Thermon to Adjusted Net Income (Loss) and Adjusted EPS), the Company generated Adjusted Net Income in YTD 2021 of $10.3 million and Adjusted EPS of $0.31 compared to $23.8 million and $0.72, respectively, during YTD 2020. Adjusted EBITDA was $30.4 million in YTD 2021 as compared to $55.0 million in YTD 2020, a decrease of $24.6 million, or 45%.

As of December 31, 2020, the Company had $169.1 million of gross outstanding debt and $49.6 million of cash and cash equivalents, representing net debt of $119.5 million. Based on the trailing twelve month Adjusted EBITDA of the Company, our net debt to trailing twelve month Adjusted EBITDA ratio was 3.0x as of December 31, 2020.

Outlook

Despite the uncertain global economic conditions, we are re-instituting revenue guidance and estimate our revenue for the quarter ending March 31, 2021 will be approximately $69-76 million. We will prioritize our capital allocation towards additional debt reduction in the near term, and target a Net Debt to Adjusted EBITDA leverage ratio of 1.5x - 2.0x under normal conditions.

Non-GAAP Financial Measures

Disclosure in this release of "Adjusted EPS," "Adjusted EBITDA,", "Adjusted EBITDA margin" and "Adjusted Net Income (Loss)" which are "non-GAAP financial measures" as defined under the rules of the Securities and Exchange Commission (the "SEC"), are intended as supplemental measures of our financial performance that are not required by, or presented in accordance with, U.S. generally accepted accounting principles ("GAAP"). "Adjusted Net Income" and "Adjusted EPS" (or "Adjusted fully diluted EPS") represent net income attributable to Thermon before costs related to restructuring, the benefit from the CEWS, costs related to the consolidation of our operating footprint in Canada, amortization of intangible assets, and the income tax effect on any non-tax adjustments, per fully-diluted common share in the case of Adjusted EPS. "Adjusted EBITDA" represents net income attributable to Thermon before interest expense (net of interest income), income tax expense, depreciation and amortization expense, stock-based compensation expense, income attributable to non-controlling interests, costs related to restructuring, the benefit from the CEWS and costs related to the consolidation of our operating footprint in Canada. "Free Cash Flow" represents cash provided by operating activities less cash used for the purchase of property, plant and equipment, net of sales of rental equipment and proceeds from sales of land and buildings.

We believe these non-GAAP financial measures are meaningful to our investors to enhance their understanding of our financial performance and are frequently used by securities analysts, investors and other interested parties to compare our performance with the performance of other companies that report Adjusted EPS, Adjusted EBITDA, or Adjusted Net Income (Loss). Adjusted EPS, Adjusted EBITDA and Adjusted Net Income (Loss) should be considered in addition to, not as substitutes for, income from operations, net income, net income per share and other measures of financial performance reported in accordance with GAAP. We provide Free Cash Flow as a measure of our liquidity. Our calculation of Adjusted EPS, Adjusted EBITDA, Adjusted Net Income and Free Cash Flow may not be comparable to similarly titled measures reported by other companies. For a description of how Adjusted EPS, Adjusted EBITDA, Adjusted Net Income, and Free Cash Flow are calculated and reconciliations to the corresponding GAAP measures, see the sections of this release titled "Reconciliation of Net Income (Loss) attributable to Thermon to Adjusted EBITDA," "Reconciliation of Net Income (Loss) attributable to Thermon to

Our forward-looking statements are not guarantees of future performance, and actual results and future performance may differ materially from those suggested in any forward-looking statements. We do not intend to update these statements unless we are required to do so under applicable securities laws.
