Arlington Capital Partners closed its $460.6M acquisition of British photonics company Gooch & Housego, securing a supplier of infrared imaging, laser weapon systems, inertial guidance, and targeting components. Arlington plans major US capacity investments to expand production as defense demand accelerates.
What's happening
- Arlington Capital Partners acquired G&H for £345.6M ($460.6M), taking the London-based photonics manufacturer private.
- In the first half of 2026, G&H's defense revenue grew 51.7 percent year-over-year and represented 43 percent of the company's £81.9M ($109M) total revenue.
- G&H's defense order book reached a record £167.3M ($223M) in the first half of 2026, with products spanning infrared imaging, laser components, gyroscopes, and targeting systems.
- Arlington plans major capacity expansion in the US, where G&H already operates in Ohio, California, Florida, New Hampshire, and New York.
Why it matters
- G&H supplies critical photonics and optical components for major weapon systems, laser weapons, inertial guidance, and counter-drone targeting across US and allied defense programs.
- Private equity backing removes quarterly earnings pressure, enabling long-term capital investments in US manufacturing capacity to meet customer demand that currently exceeds production ability.
- G&H expects aerospace and defense revenue to double within years, but cited production capacity as a limiting factor; Arlington funding addresses this supply constraint for the industrial base.
- North America represents 40 percent of current sales but the largest growth opportunity; customers explicitly demand US-manufactured photonics, making domestic capacity expansion strategically important.
Going deeper
- G&H was founded in 1948 and historically served medical, semiconductor, and telecommunications sectors, but defense has become its dominant and fastest-growing segment.
- CEO Charlie Peppiatt stated the company's rapid growth and product demand had become a limiting factor in meeting warfighter requirements, creating the opening for private capital.
- Arlington raised $6B for Fund VII in October 2025 and has deployed $14B+ across 27 years, with a recent exit in BlueHalo's $4.1B sale to AeroVironment in May 2026.
Financial impact
- Arlington funded the $460.6M acquisition from Fund VII, which closed in October 2025 with $6B in committed capital.
- As a private company, G&H will recognize revenue from defense contracts over future periods of performance as production capacity expands; current backlog of £167.3M ($223M) provides forward visibility.
- Arlington's capital injection will flow to balance sheet capex for US manufacturing facilities and equipment; timing and magnitude of these expenditures are not disclosed.
The intrigue
- G&H cited the need for products to be made in North America to serve US customers, yet Arlington's plan to expand US capacity requires significant capital investment over time, raising questions about the pace of manufacturing transfer from the UK.
The fine print
- Arlington plans capacity expansion in the US, UK, and Europe, but the company has not disclosed the specific capex budget, timeline, or which production lines will be relocated or built anew.
- G&H's customer base spans aerospace, defense, medical, and industrial; the 43 percent defense revenue share in H1 2026 may shift as capacity investments prioritize warfighter demand.
