Arcosa Files Form 15 to End SEC Registration After CRH Merger

What happened

Arcosa, Inc., a Dallas-based manufacturer of engineered construction and industrial products, filed a Form 15-12G with the SEC on November 2, 2026, to terminate registration of its common stock and suspend its duty to file periodic reports.

The filing states that the trigger was a merger that closed on October 23, 2026. Under an Agreement and Plan of Merger dated June 21, 2026, a wholly owned subsidiary of CRH Americas, Inc. called Neon Merger Sub, Inc. merged into Arcosa, with Arcosa surviving as a wholly owned subsidiary of CRH Americas.

The filing lists one holder of record of Arcosa common stock as of the certification date — a figure consistent with the company now being privately held by a single parent.

Arcosa shares last closed at $149.15, up 0.08% from the prior close of $149.03, according to the price data.

The background

Arcosa describes itself in the filing only by its commission file number and Dallas address; the filing does not restate its business. The company is listed in the data provided as a maker of fabricated structural metal products.

The merger agreement was signed on June 21, 2026, and the transaction closed about four months later on October 23, 2026. The Form 15 does not state the merger consideration paid to Arcosa shareholders, the reasons for the deal, or any other terms beyond the corporate structure that resulted.

What this means

A Form 15 is the document a company files with the SEC to switch off its public-company reporting obligations. Once it takes effect, the company no longer has to file annual reports (10-K), quarterly reports (10-Q) or current reports (8-K).

The form has several checkboxes for different legal routes. Arcosa checked Rule 12g-4(a)(1), which applies when a class of securities has fewer than 300 holders of record, and Rule 12h-3(b)(1)(i), which suspends the separate duty to file reports under Section 15(d) of the Securities Exchange Act. Both routes are available because a company with a single shareholder no longer meets the thresholds that require public reporting.

This is different from a Form 25, which is the filing that removes a security from a stock exchange listing. Arcosa's Form 15 concerns its SEC registration and reporting duties, not a delisting. The filing does not address whether or when the stock will stop trading.

The one-holder figure is the mechanical heart of the filing: registration under Section 12(g) is designed for companies whose stock is widely held, and a wholly owned subsidiary of CRH Americas no longer is. The Form 15 is the formal step that makes the SEC's records match that reality.

What happens next

Under the rules cited in the filing, the termination of registration and suspension of reporting generally become effective 90 days after the filing, or sooner in some circumstances, unless the SEC objects. The filing itself does not state an effective date.

The filing is signed by David Toolan, Arcosa's Treasurer. The company's public disclosures going forward, if any, would come from its parent, CRH Americas, rather than from Arcosa as a standalone registrant — though the filing does not describe CRH's reporting arrangements.
