(2)

Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).

Yes ☒ No ☐

(3)

Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

Yes ☒ No ☐

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

The Registrant's results of operations for the three months ended March 31, 2026 are expected to reflect a significant change from the three months ended March 31, 2025. The change is attributable primarily to the Registrant's acquisitions, completed during the 2025 fiscal year, of Carolina Stone Holdings, LLC, on August 22, 2025, and of Fraser Canyon Holdings Inc. and substantially all of the assets of Continental Stone Industries, Inc., on December 1, 2025. Because neither acquisition was reflected in the Registrant's results of operations for the three months ended March 31, 2025, the inclusion of a full quarter of operations of the acquired businesses in the current period is expected to result in materially higher net sales, cost of goods sold, gross profit and operating expenses relative to the corresponding period of the prior fiscal year. The current period will also reflect amortization of intangible assets recognized in the related purchase price allocations and increased interest expense associated with acquisition-related and other financing. The Registrant's complete results of operations, together with management's discussion and analysis, will be set forth in the Quarterly Report, which the Registrant expects to file within the extension period permitted under Rule 12b-25.
