“GMS achieved outstanding results for the fourth quarter and full year fiscal 2022,” said John C. Turner, Jr., President and Chief Executive Officer of GMS. “Our scale, balanced mix of products and customers, commitment to delivering best-in-class service and continued execution of our growth strategy, coupled with strong residential demand and an inflationary pricing environment, enabled us to deliver record levels of net sales, net income and Adjusted EBITDA. We remain optimistic about the year ahead, which, despite rising rates, is supported by a continuing fundamental underbuild of residential housing stock as well as signs of an improving commercial market.”

Turner continued, “We are also very pleased to announce that our Board of Directors has approved the repurchase of up to $200 million of the Company’s common stock. This expanded authorization demonstrates our Board’s continued confidence in the strength and future prospects of our business. We remain focused on the execution of our strategic priorities, including expanding our platform through both acquisitions and greenfield opportunities, as well as enhancing our product and service offerings and delivering improved profitability as we leverage technology and best practices to achieve advancements in productivity. Looking ahead, we are committed to driving long-term shareholder value with a disciplined capital allocation strategy that balances investing in our organic growth initiatives, pursuing accretive M&A transactions and opportunistically leveraging favorable market conditions for share repurchases as they arise.

Fourth Quarter Fiscal 2022 Results

Net sales for the fourth quarter of fiscal 2022 of $1.29 billion increased 38.2% as compared with the prior year quarter, primarily due to inflationary pricing, healthy residential end market demand, strong performance from our complementary products and the acquisitions of Westside Building Material and AMES Taping Tools. Organic net sales increased 28.9%.

Excluding the impact from one less selling day in the fourth quarter of fiscal 2022 compared to the same period a year ago, net sales and organic net sales were up 40.4% and 30.9%, respectively.

Fourth quarter year-over-year sales increases by product category were as follows:

· Wallboard sales of $491.1 million increased 30.3% (up 26.5% on an organic basis).

· Ceilings sales of $148.9 million increased 22.7% (up 17.0% on an organic basis).

· Steel framing sales of $276.9 million increased 93.3% (up 81.6% on an organic basis).

· Complementary product sales of $371.8 million increased 27.9% (up 11.1% on an organic basis).

Gross profit of $412.8 million increased 40.5% compared to the fourth quarter of fiscal 2021, and gross margin improved 50 basis points to 32.0%, both primarily due to the successful pass through of product price inflation, continued strength in residential market demand and incremental gross profit dollars along with accretive gross margins from acquisitions.

Selling, general and administrative (“SG&A”) expense as a percentage of net sales improved 170 basis points to 20.5% for the quarter compared to 22.2% in the fourth quarter of fiscal 2021. Adjusted SG&A expense as a percentage of net sales of 20.2% improved 170 basis points from 21.9% in the prior year quarter as product price inflation outpaced increases in operating costs.

Net income increased 126.7% to $76.5 million, or $1.75 per diluted share, compared to net income of $33.7 million, or $0.77 per diluted share, in the fourth quarter of fiscal 2021. Adjusted net income was $91.3 million, or $2.09 per diluted share, compared to $46.9 million, or $1.07 per diluted share, in the fourth quarter of the prior fiscal year.

Adjusted EBITDA increased $63.0 million, or 69.1%, to $154.2 million compared to the prior year quarter. Adjusted EBITDA margin of 12.0% improved 220 basis points from 9.8% for the fourth quarter of fiscal 2021.

Balance Sheet, Liquidity and Cash Flow

As of April 30, 2022, the Company had cash on hand of $101.9 million, total debt of $1.2 billion and $330.7 million of available liquidity under its revolving credit facilities. Net debt leverage was 1.8 times as of the end of the quarter, down from 2.5 times at the end of the fourth quarter of fiscal 2021.

The Company generated cash from operating activities and free cash flow of $199.5 million and $191.6 million, respectively, for the quarter ended April 30, 2022. For the quarter ended April 30, 2021, the Company generated cash from operating activities and free cash flow of $84.8 million and $72.8 million, respectively.

Expanded Share Repurchase Authorization

Use of Non-GAAP Financial Measures

GMS reports its financial results in accordance with GAAP. However, it presents Adjusted net income, free cash flow, Adjusted SG&A, Adjusted EBITDA, and Adjusted EBITDA margin, which are not recognized financial measures under GAAP. GMS believes that Adjusted net income, free cash flow, Adjusted SG&A, Adjusted EBITDA, and Adjusted EBITDA margin assist investors and analysts in comparing its operating performance across reporting periods on a consistent basis by excluding items that the Company does not believe are indicative of its core operating performance. The Company’s management believes Adjusted net income, Adjusted SG&A, free cash flow, Adjusted EBITDA and Adjusted EBITDA margin are helpful in highlighting trends in its operating results, while other measures can differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which the Company operates and capital investments. In addition, the Company utilizes Adjusted EBITDA in certain calculations in its debt agreements.

You are encouraged to evaluate each adjustment and the reasons GMS considers it appropriate for supplemental analysis. In addition, in evaluating Adjusted net income, Adjusted SG&A and Adjusted EBITDA, you should be aware that in the future, the Company may incur expenses similar to the adjustments in the presentation of Adjusted net income, Adjusted SG&A and Adjusted EBITDA. The Company’s presentation of Adjusted net income, Adjusted SG&A, Adjusted SG&A margin, Adjusted EBITDA, and Adjusted EBITDA margin should not be construed as an inference that its future results will be unaffected by unusual or non-recurring items. In addition, Adjusted net income, free cash flow, Adjusted SG&A and Adjusted EBITDA may not be comparable to similarly titled measures used by other companies in GMS’s industry or across different industries. Please see the tables at the end of this release for a reconciliation of Adjusted EBITDA, free cash flow, Adjusted SG&A and Adjusted net income to the most directly comparable GAAP financial measures.

When calculating organic net sales growth, the Company excludes from the calculation (i) net sales of acquired businesses until the first anniversary of the acquisition date, and (ii) the impact of foreign currency translation.
