GMS REPORTS FIRST QUARTER FISCAL 2024 RESULTS

Strong Multi-Family, Growth in Commercial Activity, and Resilient Pricing Drive Solid Results

Tucker, Georgia, August 31, 2023. GMS Inc. (NYSE: GMS), a leading North American specialty building products distributor, today reported financial results for the fiscal first quarter ended July 31, 2023.

First Quarter Fiscal 2024 Highlights

(Comparisons are to the first quarter of fiscal 2023)

“We were pleased to deliver a solid start to fiscal 2024 with first quarter results that were in line with our expectations, continuing to demonstrate the resilience of pricing in Wallboard, Ceilings and Complementary Products, as well as the strength and stability that our balanced end markets provide,” said John C. Turner, Jr., President and Chief Executive Officer of GMS. “Multi-family and commercial construction demand remained solid during the quarter, which helped to offset declines in steel pricing and tempered single-family demand as we felt the impacts of the lower level of housing starts recorded earlier this year and in the latter half of calendar 2022.”

“Despite our realizing the expected near-term year-over-year declines for single-family construction activity amid 20-year highs in interest rates, we are seeing favorable demand conditions develop as we look forward. While Steel Framing pricing and soft office demand remain headwinds, we are seeing sequentially improving US single-family permits and starts, still solid multi-family activity, and put-in-place construction spending growth in most commercial applications. Given our scale, wide range of product offerings and expertise in providing outstanding service to each of our end markets, we believe we are well positioned for future growth and to deliver value to our shareholders.”

First Quarter Fiscal 2024 Results

Net sales for the first quarter of fiscal 2024 of $1.4 billion increased 3.7% as compared with the prior year quarter, or 2.1% on a same day basis. This increase in net sales was primarily due to contributions from recent acquisitions, resilient pricing in Wallboard, Ceiling tiles and Complementary Products along with strong levels of multi-family construction activity and continuing commercial construction demand. These factors helped to offset declines in single-family construction and a challenging pricing environment in Steel Framing. Organic net sales, which exclude the first year of acquired business net sales as well as the impact of foreign currency translation, grew 1.0% in total but declined 0.6% on a per day basis.

Year-over-year quarterly sales changes by product category were as follows:

● Wallboard sales of $571.4 million increased 9.6% (up 9.3% on an organic basis).

● Ceilings sales of $175.2 million increased 4.7% (up 2.0% on an organic basis).

● Steel Framing sales of $236.8 million decreased 13.9% (down 15.0% on an organic basis).

● Complementary Product sales of $426.2 million increased 7.7% (up 0.7% on an organic basis).

Gross profit of $450.6 million increased 3.6% compared to the first quarter of fiscal 2023 primarily due to incremental gross profit from acquisitions, the continued pass through of product inflation in Wallboard, Ceilings and Complementary Products and growth in commercial and multi-family sales volumes. Gross margin of 32.0% was unchanged from a year ago.

Selling, general and administrative (“SG&A”) expenses of $286.8 million during the quarter, up from $267.7 million, were negatively impacted by acquired businesses, inflationary wages, higher maintenance costs and demand pullbacks in single-family construction, which resulted in a relative mix shift into multi-family and commercial end market volumes. This shift, while favorable to gross margin, also required a higher operational cost to serve. As a result, SG&A expense as a percentage of net sales, which was also significantly impacted by deflationary dynamics in steel pricing, increased 60 basis points to 20.3% for the quarter compared to 19.7% in the first quarter of fiscal 2023. Adjusted SG&A expense as a percentage of net sales of 19.8% increased 60 basis points from 19.2% in the prior year quarter.

All in, inclusive of a $4.3 million, or 29.0%, increase in interest expense and a $1.4 million one-time expense related to the Company’s May 2023 term loan refinancing, which were partially offset by a one-time tax planning rate benefit, net income decreased 3.0% to $86.8 million, or $2.09 per diluted share, compared to net income of $89.5 million, or $2.07 per diluted share, in the first quarter of fiscal 2023. Net income margin declined 40 basis points from 6.6% to 6.2%. Earnings per share outpaced net income as a result of the $117.4 million in share repurchases completed since the end of July 2022. Adjusted net income was $99.6 million, or $2.40 per diluted share, compared to $105.2 million, or $2.43 per diluted share, in the first quarter of the prior fiscal year.

Adjusted EBITDA decreased $1.7 million, or 1.0%, to $173.3 million compared to the prior year quarter. Adjusted EBITDA margin was 12.3%, compared with 12.9% for the first quarter of fiscal 2023.

Balance Sheet, Liquidity and Cash Flow

As of July 31, 2023, the Company had cash on hand of $81.4 million, total debt of $1.1 billion and $816.2 million of available liquidity under its revolving credit facilities. Net debt leverage was 1.5 times as of the end of the quarter, down from 1.8 times at the end of the first quarter of fiscal 2023.

For the first quarter of fiscal 2024, which seasonally represents the highest use of cash for the Company, cash provided by operating activities improved to $6.6 million, compared to cash used by operating activities of $4.4 million in the prior year period. Free cash flow use improved to $6.9 million for the quarter ended July 31, 2023, compared to a use of $15.3 million for the quarter ended July 31, 2022.

During the quarter, the Company repurchased 468,949 shares of common stock for $30.5 million. As of July 31, 2023, the Company had $69.6 million of share repurchase authorization remaining.

Platform Expansion Activities

Home Lumber is a leading supplier of lumber, engineered wood, doors, framing packages and siding as well as other key Complementary products offered by GMS Canada.

In addition during the quarter, the Company added a new AMES store location in San Antonio, TX.

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.
