LONDON, Feb 26 (Reuters Breakingviews) - London Stock Exchange Group (LSEG.L), opens new tab is borrowing from the activist investor playbook, but only to a limited extent. The $57 billion data-to-exchange group on Thursday announced, opens new tab a share buyback alongside new revenue growth and EBITDA margin targets. The moves reinforce the case that artificial intelligence won’t kill the group, and should also go some way to pleasing pushy investor Elliott Management. But LSEG boss David Schwimmer will need to show he can keep reviving the depressed stock.

Schwimmer is doubly under pressure. Before Thursday, LSEG’s shares had fallen nearly 30% in a year, amid fears that AI groups like Anthropic could replace or undercut financial data companies. And Elliott, known for sometimes hostile activist campaigns, popped up with a shareholding, raising expectations of a large share buyback, opens new tab, cost cuts and asset sales. LSEG is the largest customer of Breakingviews’ owner Reuters, which provides news for the Workspace terminal and other products.

While Elliott has not publicly articulated its demands, Schwimmer’s moves only go some way to meeting those that have been reported. LSEG’s new 3-billion-pound share buyback is twice analysts’ expectations, but trails the 5 billion pounds possible target that Elliott might have wanted, as suggested by a Reuters report. And Schwimmer seems opposed to radically changing the LSEG structure, which includes business from clearing, indexes, post-trade services as well as bourses.

The case for such radical change, so far, is unclear. Selling down stable and richly valued assets like Tradeweb Markets (TW.O), opens new tab, or taking on more debt to turbocharge buybacks, would leave LSEG with less flexibility. Shareholders may also end up more exposed to the businesses that may be vulnerable to AI disruption.

Schwimmer’s best defence, both to market panic and Elliott, is to show that his plan is working. Hence Thursday’s stated ambition to grow revenue at a “mid to high single digit” rate between 2027 and 2029, and to boost the EBITDA margin by 1.5 percentage points. While those targets are broadly consistent with analysts’ expectations, per Visible Alpha data, they should reassure that AI destruction is not on the horizon. LSEG is also providing more data on how AI is boosting its business. That includes giving the number of new customers plugging its data into AI models, or the fact that LSEG has achieved a 51% reduction in data quality issues over four years. Additional disclosure on customer retention rates and new product use may also help.

A 6% share price bump on Thursday should buy Schwimmer time from Elliott and other shareholders. LSEG is now worth around 18 times forward earnings, in line with typically more lowly-rated European exchanges Euronext (ENX.PA), opens new tab and Deutsche Boerse (DB1Gn.DE), opens new tab. Yet it’s still at a 28% valuation discount to U.S. peers MSCI (MSCI.N), opens new tab, S&P Global (SPGI.N), opens new tab and CME (CME.O), opens new tab, which on average trade at 25 times forward earnings. The case for sticking with Schwimmer’s activist-lite plan rests on closing that gap.
