Why is Bytes Technology stock sliding today?

Bytes Technology's stock plummeted nearly 3.8% to £444.5 today following the release of first-half results and the acquisition of CyberOne. The company reported a 18.7% revenue increase to £128.3 million and a 17.8% rise in gross profit to £97.1 million for the six months ended August 31, 2026. However, operating profit only grew 6.6% to £35.3 million, and the operating profit margin narrowed from 40.2% to 36.4% of gross profit.

Investors appeared unsettled by this disparity, despite the stock previously reaching a fresh 52-week high of £489.2. Bytes announced the acquisition of CyberOne for an initial £19.4 million, funded by existing cash with additional payments over 16 months. The company expects CyberOne's post-acquisition operating profit to be offset by intangible asset amortisation, with earnings enhancement only forecast from FY28 onwards.

The combination of cost normalisation charges and the £41.3 million shareholder payout reduced the closing cash balance to £68.4 million, despite the £25 million share buyback. The broader UK market showed no support, as the FTSE 100 and FTSE 250 both edged higher, making Bytes' decline a company-specific event. The board maintained a low to mid-single-digit operating profit growth outlook for the full year, but the market treated the results as a sell-the-news moment following a significant share price rally triggered by a September guidance upgrade.
