- • Gooch & Housego, a Somerset-based specialist in photonics and optical engineering, becomes a privately held entity following Arlington Capital's initial unsolicited proposals that were subsequently rejected before a board-recommended offer materialized in July 2026.
- • The deal values the historic engineering company at approximately £400 million on an enterprise value basis, reflecting significant strategic interest in the photonics sector from US private equity.
Summary
Arlington Capital Partners has successfully navigated US antitrust scrutiny in its pursuit of Gooch & Housego, with clearance under the Hart-Scott-Rodino Act allowing the £346 million acquisition to advance toward completion. The transaction, initially announced in July 2026, represents Arlington Capital's entry into the UK photonics and specialist engineering market through the acquisition of the Ilminster, Somerset-based firm.
The path to this regulatory approval included multiple unsolicited proposals from Arlington Capital that G&H's board initially rejected before eventually recommending the final offer to shareholders. At shareholder meetings, the transaction received substantial backing, with 92.5% of shareholders voting in favor at the court meeting and approximately 79% of voting shares supporting the deal. The agreed price of 1,234.9 pence per share values the company at £345.6 million, with enterprise value assessments placing the broader deal valuation at approximately £400 million.
While the HSR clearance represents a significant regulatory milestone, the acquisition remains subject to additional approvals. Most notably, the transaction must still satisfy requirements under the UK National Security and Investment Act 2021, a screening mechanism for foreign acquisitions of sensitive UK assets. Subject to these remaining conditions being satisfied or waived, G&H's board expects the scheme to become effective during Q4 2026, positioning the deal for completion by year-end.
The acquisition underscores continued private equity appetite for specialized engineering and photonics capabilities within the UK industrial base, with Arlington Capital's successful navigation of cross-border regulatory requirements demonstrating the increasing complexity of transatlantic M&A in strategically sensitive sectors.
