Citi has initiated coverage of Bel Fuse Inc., the US-based manufacturer of electronic components, with a 'buy' rating, highlighting the company's growing exposure to the artificial intelligence sector. The move comes as investors increasingly seek out firms supplying the hardware backbone for AI data centres, from power management systems to connectivity solutions.
Bel Fuse, which designs and makes products including circuit protection devices and power supplies, has seen its stock gain traction on the back of rising demand from cloud computing and AI infrastructure projects. Citi's analysts noted that the company's niche position in high-reliability components makes it a potential beneficiary of the ongoing AI build-out, particularly as hyperscalers ramp up capital expenditure.
While Bel Fuse is listed in the US, the rating has implications for UK investors and pension funds with exposure to global technology equities. The FTSE 100 edged up 0.3% to 8,212.45 in early trading on Friday, while the technology-heavy Nasdaq Composite saw futures rise, reflecting a broader appetite for AI-related names. Shares in UK-listed tech suppliers such as XP Power and Renishaw also traded higher, suggesting a spillover effect across the sector.
Analysts at Citi said in a note that Bel Fuse's revenue mix is shifting toward higher-growth segments, with AI data centre applications now accounting for a growing share of sales. 'The company is well positioned to capitalise on the secular trend of electrification and AI-driven data demand,' they wrote, though they cautioned that supply chain constraints and competition remain risks.
For UK investors, the rating serves as a reminder of the widening AI investment opportunity beyond the usual suspects like Nvidia. Smaller component makers, often overlooked, are increasingly seen as critical links in the AI value chain. However, with valuations stretched in some areas, analysts advise focusing on companies with tangible revenue exposure rather than speculative plays.
