Karen Egan, head of telecoms at Enders Analysis, also said the CMA appears to have all but approved the proposed Vodafone-Three merger.

Writing on LinkedIn, Egan said the CMA believes that the merger could be pro-competition “so long as it can be assured that the network promises of the merging parties will be fulfilled, and that the short-term customer protections that it talked about in its provisional findings (social tariffs, contract terms rolling over, wholesale reference offer) can be put in place.”

Egan pointed out that this is a step forward from the CMA’s provisional findings, “where it put forward such remedies, but also discussed structural remedies (although largely discounted them), and listed blocking the merger altogether as a remedy (which it did not discount).”

Three, which tends to have a younger customer base, generally has some of the cheapest monthly contracts among the four biggest mobile network operators, according to figures from Enders Analysis.

However, telecoms analysts are not convinced that the tie-up will necessarily lead to higher prices. “There doesn’t seem to be a correlation between fewer mobile players and consumer pricing,” said Karen Egan, head of telecoms at Enders Analysis.

James Barford, director of telecoms at Enders Analysis, says convincing investors of the company’s fibre broadband strategy is Kirkby’s greatest success. “Rolling out full fibre into 30 million homes is a huge undertaking.

“Under previous management they suspended the dividend [in 2020], the first time since privatisation in 1984, in order to pay for it, saying that when they finished the rollout it would increase free cashflow to £3 billion a year by the end of the decade.”

Barford says that Kirkby, BT’s first female chief executive, has convinced investors that the fibre rollout (which has been much slower than in other European countries) will happen and will make money in the long run.

“The reason the share price is up is because she is getting everything right, giving clear forward guidance and, importantly, sticking to BT’s core purpose. There is still a long way to go but it appears the full success is not priced in.”

A report from Enders Analysis has argued that generative artificial intelligence “will not alter the fundamental commercial reality for the news” as the shift online did previously.

The research firm cautioned publishers to be “realistic” about the productivity and revenue gains possible from AI, but added that ignoring AI would be “a mistake”.

The report found there have been some valuable uses for AI in the newsroom — but argued that there may not be an “immediate, killer news use case to raise revenues”.

AI can also help to create “more sophisticated metadata for archival material”, they wrote, in turn making it easier for journalists and readers to access a publisher’s back catalogue. This could have revenue implications for local publishers in particular, they said, “where some historical material has barely been digitised”.

“Increased regulatory pressure could be behind this new publisher push,” said Niamh Burns, senior research analyst in tech and media at Enders Analysis. “From TikTok’s perspective, it helps to have fact-checked, informative news publisher content on TikTok to counter any narrative around disinformation or platform bias.”

But as she pointed out, publishers don’t make money on TikTok, at least not yet. “Until this improves it’ll remain an arms-length relationship for a lot of publishers,” Burns added. “TikTok isn’t a referral channel, and publishers need to balance getting their brand in front of young people with the risk of getting lost in the content mix.”

This was mainly driven by rising interest costs, which account for more than 100pc of alt-nets’ turnover on average, according to figures from Enders Analysis.

Enders said the tie-up could help CityFibre win market share from BT and Virgin Media O2 but warned there were limited wholesale prospects for smaller alt-nets.

The amount of money raised so far this year is barely enough to cover losses and interest charges – let alone to fund continued network expansion, Enders said.
