Recovery Analysis

The U.K.’s Competition and Markets Authority has cast doubt on the proposed acquisition of Netomnia’s parent Substantial Group by Nexfibre, putting at risk a key pillar of U.K. telecom operator Virgin Media O2’s deleveraging plan. If the deal is blocked outright by the antitrust regulator, VMED O2 would lose out on roughly £950 million of upfront cash payable by Nexfibre, a fiber venture backed by VMED O2’s parents Liberty Global and Telefonica, reducing its immediate capacity to deleverage.

Nevertheless, the loss of that upfront cash would not necessarily leave VMED O2 worse off. Over the medium term, we believe VMED O2 would retain the economics of serving customers over its own network, preserving infrastructure earnings and asset value alongside the retail customer relationship.

This reflects the trade-off at the heart of the proposed tie-up. In exchange for upfront cash and a lower investment burden for upgrading its network, VMED O2 would shift part of those economics to Nexfibre, paying it recurring wholesale access fees for each customer. Our modeling shows that avoiding those wholesale access fees offsets much of the cost of funding the affected fiber upgrade itself. As such, abandoning that investment could leave cash generation stronger through 2029, the period we’ve investigated, although the resulting underinvestment could weaken the network’s competitiveness and longer-term value.

We think it unlikely the transaction will be approved under its original terms given the CMA’s Oct. 2 provisional findings. As previously reported, CMA’s findings identify U.K. fiber network operator CityFibre as a viable bidder for Substantial Group, if the Nexfibre deal is not pursued. Separately, CityFibre said in its Oct. 6. trading update that it was in discussions with lenders to strengthen its capital structure, alongside a proposed £900 million equity commitment from shareholders to support potential acquisitions.

CityFibre’s network has little overlap with Netomnia’s, whereas VMED O2 and Nexfibre have significant geographic overlap with Netomnia. The regulator’s concern is that a Nexfibre acquisition of Netomnia would leave certain affected areas with only two independent wholesale network competitors, rather than the three under a CityFibre ownership of Netomnia, lessening competition on broadband access prices. We note that to date, the findings remain provisional and possible remedies could allow the transaction to proceed. We discuss the competitive dynamics of the U.K. broadband sector and the CMA’s findings HERE.

About 2.5 million of the 3.4 million premises within Netomnia’s expected footprint at completion of the transaction already fall within VMED O2’s network area. While the transaction would spare VMED O2 part of the cost of upgrading its network to fiber, it would commit it to paying Nexfibre for access in areas where it already serves customers. Those customers would remain VMED O2 retail customers, while the wholesale fees to be paid to Nexfibre would transfer, on a recurring basis, a portion of the cash they generate outside VMED O2’s restricted group.

To assess the potential financial implications for VMED O2, we model three scenarios: (1) the proposed transaction is rejected and VMED O2 funds the affected fiber upgrade itself; (2) the deal is rejected and the operator abandons the upgrade program; or (3) the transaction proceeds with regulatory remedies.

In our illustrative operating base case where the proposed deal is rejected but VMED O2 funds the affected upgrade itself, we estimate that the annual levered free cash flow will be about £35 million below our previous expectations, which included an approved-deal, by 2029. By that point, avoided wholesale charges largely offset the additional network spending. However, net debt would nevertheless be about £1.3 billion higher at that time than in our previous forecasts, reflecting the impact on leverage of the missing upfront cash payment and weaker cumulative cash generation throughout the upgrade. The recurring cash-flow gap narrows, but the lost opportunity for upfront deleveraging persists.

In an alternative scenario where the proposed deal is rejected and VMED O2 also abandons the affected upgrade program, our model shows annual levered free cash flow of about £200 million above our previous expectations for 2029. In this scenario VMED O2 avoids both the network investment and the associated wholesale fees, while continuing to serve customers over its existing network. However, we would note the cash-flow benefit is dependent on customer losses and pricing pressure building gradually enough for the savings to outweigh the damage to earnings. VMED O2 keeping its older network in service for a longer period of time would likely improve cash generation through 2029 but leave a larger competitive challenge in the medium term as the company will not benefit from the associated fiber upgrade.

A third scenario could see the transaction proceed with regulatory remedies designed to address the CMA’s competition concerns, potentially preserving some of the deal’s benefits. Our illustrative remedy scenario assumes the overlapping portions of Netomnia’s network are sold to an independent buyer, leaving VMED O2 in receipt of a smaller upfront cash payment, fewer acquired retail customers and a narrower wholesale commitment. Annual cash flow remains close to the original proposal in that scenario. However, removing the overlap also removes much of the existing VMED O2 customer traffic supporting the transaction’s economics, potentially making the remaining package harder to justify and finance.
 

Should the deal proceed on its original terms, which seems very unlikely at this time, VMED O2’s net debt at the end of 2029 would be the lowest across our scenarios. The roughly £950 million of net cash expected at completion under the current deal’s terms provides an immediate reduction in net debt. None of the alternatives fully recover that benefit over the forecast period, even where annual cash generation improves from lower wholesale fees or upgrade expenses.

If the deal falls apart and VMED O2 chooses to fund the affected upgrades itself, the missing upfront proceeds accounts for most of the £1.3 billion in additional net debt we see for year-end 2029. The remainder reflects roughly £360 million of lower cumulative levered free cash flow between 2027 and 2029 as VMED O2 pays for the upgrade program, which is partially offset by avoided wholesale charges, bringing annual cash generation close to our current estimates incorporating the original proposal by 2029. However, even as the gap narrows in later years, the earlier funding shortfall remains outstanding.

Alternatively, VMED O2 could decide that, absent the combination, the affected fiber upgrades are uneconomic and therefore abandon its upgrade program. Avoiding the upgrade costs and the associated wholesale fees no longer due to Nexfibre under a rejected Netomnia deal leaves VMED’s cumulative levered free cash flow about £420 million higher over 2027–2029 than under the original transaction terms. That figure already allows for the additional customer losses and pricing pressure assumed in the model. This recovers less than half the missing upfront proceeds, leaving net debt roughly £530 million higher at the end of the period. The stronger cash generation we see in such a scenario is also dependent on the amount of earnings that would be lost through greater competition being less severe than the avoided investment and wholesale fees. This also elides the long-term damage to the competitiveness of VMED’s network resulting from the abandonment of the upgrade cycle.

It is possible that VMED may be able to salvage a part of the deal by remediating some of the regulator’s largest concerns. Such a remedy could retain part of the upfront payment and Nexfibre’s investment commitment. However, under our illustrative terms, VMED O2 would receive less cash and need to fund more of the upgrade program itself. The resulting annual cash flows would remain close to the original proposal, while the smaller initial payment under such a scenario would leave a higher net debt balance at the end of the forecast period.

Avoiding the wholesale fees paid to Nexfibre under the transaction as currently proposed would also allow VMED O2 to retain more of the EBITDA generated from its own network, keeping the company’s net leverage relatively close across our scenarios, despite the differences in net debt. The ratio would be about 5.1x in 2029 under both the original proposal and the self-funded upgrade scenario, falling to 4.9x in the no-upgrade case, reflecting the higher retained EBITDA and the cash saved by canceling the affected investment.
 

Under the original terms of the transaction, Nexfibre would pay VMED O2 £1.1 billion in exchange for a wholesale commitment on the Netomnia network. VMED O2 would separately pay £150 million for YouFibre and Brsk – the retail broadband brands also owned by Substantial Group – which are expected to have about 500,000 retail customers at completion. This would leave approximately £950 million of cash to the benefit of VMED before accounting for transaction costs.

VMED’s wholesale commitment under the transaction covers two distinct areas. Of Netomnia’s expected 3.4 million-premise footprint at completion, 2.5 million premises overlap VMED O2’s existing network while approximately 900,000 sit outside it. Nexfibre is also obligated to fund fiber upgrades across another 2.1 million existing VMED O2 premises. Together, the overlapping and additional upgrade areas account for the 4.6 million-premise footprint covered by VMED O2’s upgrade commitment under the transaction. These customers would be serviced by VMED O2’s own network should the deal not go through, and under the transaction as currently situated represent some leakage of value to the Nexfibre silo. If the deal does go through, VMED will be paying Nexfibre for wholesale access across this entire 5.5 million premise footprint, even those premises it brought to the table.

Wholesale access charges covering VMED O2’s overlapping customers would begin at completion of the transaction. The wholesale charges in the additional upgrade areas are slated to begin as fiber becomes available, but even includes fees for customers continuing to use the existing hybrid fiber-coaxial, or HFC, network. VMED O2 would retain the retail relationships, while Nexfibre would own the acquired fiber network and the additional fiber infrastructure it funds. The availability-based charging structure under the transaction means VMED O2 could begin paying wholesale access charges before customers migrate to fibre.

We assume a wholesale charge of £17.17 per customer per month, using BT Openreach’s pricing as a proxy, with 2% annual increases, although the specific economics could differ materially. Total access payments made by VMED O2 would also rise as fiber becomes available across the additional 2.1 million-premise upgrade area, bringing more VMED O2 customers into the wholesale arrangement. Our forecast assumes this happens gradually over the 2027–2029 period.
 

The three alternative scenarios described above all start with the same base operating forecast, with adjustments then made for the retail customer base, upgrade spending, wholesale charges and competitive pressure in the overlapping areas. We also adjust the construction and managed-service earnings attributed to the transaction.

Remedies

Our illustrative remedy scenario assumes the entire 2.5 million-premise overlapping Netomnia footprint is sold to an independent buyer such as CityFibre. In this scenario, Nexfibre retains the approximately 900,000 Netomnia premises outside VMED O2’s network and commits to fund the additional 2.1 million-premise upgrade area. VMED O2 would fund the remaining work in the overlap itself, comprising 1.7 million network upgrades and connections for its customers within that area.

We scale the upfront cash payment to the smaller network package and the retail acquisition to the retained Netomnia footprint, although obviously, this is a simplifying assumption and the actual transaction terms may not match. This leaves approximately £560 million of upfront cash after the retail purchase and before transaction costs, alongside about 130,000 acquired customers.

VMED O2 Funds the Upgrade

The self-funded upgrade case follows the CMA’s provisional expectation that, if the transaction fails, CityFibre would most likely acquire Substantial Group, while VMED O2 would continue upgrading its network.

We distinguish the cost of installing fiber across the network from the subsequent cost of connecting customers. Liberty, VMED O2’s corporate parent, identified in their fourth quarter 2025 presentation avoided network upgrade spending across 3.8 million premises and avoided customer connection spending across a 4.6 million-premise footprint as a driver for pursuing this transaction. Our model uses those separate populations as well and we assume £100 per premise for the network upgrades and £300 for each customer connection, applying the same 29.5% penetration assumption as the company to estimate the number of connections required. Spending is spread across 2027 through 2029.

VMED O2 would retain ownership of the upgraded infrastructure and avoid the transaction-related wholesale commitment. Both failed-deal cases also exclude the impact of the retail acquisition and the construction and managed-service earnings attributed to the proposed transaction. They retain the group’s existing nexfiber arrangements.

VMED O2 Abandons the Upgrade

In this scenario we assume VMED O2 concludes that stronger competition from the CityFibre-Netomnia combination makes the expected return insufficient to justify the investment in its upgrade program. In this scenario, it cancels the incremental program while continuing ordinary network spending and serving customers over its existing infrastructure.

Our model removes spending on the full program of 3.8 million network upgrades and customer connections across the 4.6 million-premise footprint as a reflection of this. The additional customer losses and pricing pressure assumed in this scenario apply only to the 2.5 million premises in the overlapping areas.

We assume those competitive pressures build gradually. By 2029, additional annual customer losses reach the equivalent of 5% of the estimated overlap customer base, compared with 2.5% in the self-funded upgrade case. Monthly revenue per customer in the overlapping areas is assumed to be £2.25 below our common operating forecast, compared with only £1.50 below it if VMED O2 upgrades the network.

These assumptions allow VMED O2 to keep serving most of its customers through the forecast period while accepting greater losses and weaker pricing. We would note, however, that prolonged reliance on the existing network is likely to intensify consumer pressures beyond 2029 and require investment in later years.
 

Netomnia’s original valuation implied a value of approximately £544 per premise for the network based on the £2 billion headline enterprise value, less the £150 million retail purchase price, spread across the expected closing footprint of 3.4 million premises. This appeared demanding against the disclosed construction costs of £250 per home, and the £307 to £466 per premise in Ofcom’s modelled construction-cost range. A substantial remedy to the CMA’s deal concerns could remove some of the benefits that helped justify the initial premium.

There are some reasonable justifications for such a premium. Buying Netomnia avoids the time and execution risk of building a comparable footprint while providing infrastructure already carrying customer traffic, which, in our view, warrants an increment to construction costs.

The wider transaction gives Nexfibre access to VMED O2’s existing customers through the wholesale commitment, providing revenue without first having to win those customers from another operator. VMED O2 would in turn reduce its investment burden and receive construction and managed-service income.

A divestment of Netomnia’s network covering the overlapping areas would weaken the investment rationale. Under our illustrative remedy, Nexfibre would give up almost three-quarters of Netomnia’s expected footprint and much of the existing VMED O2 customer traffic supporting the wholesale business plan. VMED O2 would also retain more of the investment burden in those areas.

Divestment proceeds could reduce Nexfibre’s funding requirement, and a lower purchase price could help restore the economics. The difficulty would be agreeing terms that compensate for the lost revenues and strategic benefits. We therefore see a substantial structural remedy as requiring a fundamental renegotiation of the transaction. Its acceptability would depend on the returns available to Nexfibre’s investors and lenders, and we are not particularly optimistic that a viable alternative is achievable.
 

We believe that BT’s acquisition of TalkTalk strengthens the commercial argument for building a larger challenger to the incumbent. On Oct. 5, U.K. telco BT acquired TalkTalk’s consumer business and its wholesale operation, PXC, out of administration on a debt-free basis. The acquisition brings approximately 1.5 million retail customers into the BT group, alongside a wholesale business serving another million customers.

The purchase consideration illustrates the opportunity created by TalkTalk’s distress. The upfront consideration was just £3 million, alongside additional funding commitments and the assumption of certain trade liabilities. BT nevertheless expects an approximately £400 million cash impact in its current financial year, including transaction costs, working capital, trading losses and amounts otherwise due to Openreach.

In our view, BT gaining TalkTalk’s customer base gives VMED O2 and Nexfibre a stronger argument that competing effectively requires greater scale. It may be difficult for the CMA to justify handing 1.5 million additional customers to BT, the largest network provider, while blocking its closest challenger from consolidating networks to operate competitively.

BT ownership could also influence TalkTalk’s and PXC’s future network purchasing decisions, subject to existing contracts and the regulatory outcome. That could reduce the customer traffic available to independent networks over time, affecting both Nexfibre and CityFibre.

The regulatory cases nevertheless have different starting points. BT’s acquisition remains under review, with the government considering continuity of essential services and the protection of vulnerable customers alongside competition. Completion of the deal has not settled its regulatory treatment.

In the Netomnia case, the CMA identifies CityFibre as a viable alternative buyer, which would preserve an additional independent access network. TalkTalk’s PXC unit, by contrast, purchases access from network operators and aggregates it for other providers. Its acquisition presents a different competition question from combining overlapping access networks.

TalkTalk’s collapse adds weight to the argument that the sector needs financially sustainable operators. However, clearing the Netomnia transaction would still require the CMA to reconsider, or the parties to address, its specific concern about the competition lost under Nexfibre ownership.
 

Keeping Netomnia outside VMED O2 and Nexfibre could preserve some indirect protection against more aggressive Openreach pricing. Ofcom restricts discounts that could prevent developing altnets from building sustainable customer bases. It treats VMED O2’s established network and existing customers differently, including when considering its prospects as a wholesale provider. VMED O2 can therefore benefit from restrictions intended to protect independent networks operating in the same areas.

If Netomnia joined VMED O2 and Nexfibre, Openreach could have a stronger case for deeper local discounts where no independent challenger remained. Lower wholesale charges could support cheaper offers from retail providers using Openreach, increasing pressure on VMED O2’s pricing and customer retention. In our view, retaining an independent altnet could help constrain that response, partly offsetting the competitive pressure the altnet itself creates.

This protection is conditional. Ofcom assesses offers individually and has already allowed a targeted connection rebate in VMED O2 areas, including areas where altnets also operate. The size and terms of the discount, and its effect on developing competition, influence the decision as we discussed HERE.
 

The provisional findings from the CMA weaken the case for treating Netomnia’s price as a benchmark for other altnets. Where an acquisition target substantially overlaps VMED O2, the risk of regulatory intervention likely makes Nexfibre a less credible bidder or reduces the price it is prepared to offer. Sellers would have less negotiating power if they can no longer rely on competing bids from buyers with different strategic reasons to pay a premium.

Substantial Group’s final sale process had two bidders, Nexfibre and CityFibre. Removing or weakening one potential buyer from future sales processes could materially change the balance of power in comparable auctions. This could strengthen CityFibre’s position as an altnet consolidator, increasing the pressure on retail altnets to secure transactions sooner.

For networks still consuming cash, holding out for a higher price requires investors to fund the intervening losses. As liquidity is used up, the ability to reject an offer can weaken even if the physical network continues to expand. A buyer able to bring customer traffic and operating scale may become more valuable to the business while having less reason to pay a generous price to its existing owners.
