London, UK – In a high-stakes, uncompromising intervention that has sent shockwaves through the UK telecommunications sector, nexfibre Chief Executive Rajiv Datta has launched a fierce critique of the Competition and Markets Authority (CMA). Speaking from the Fibre Investment Stage at Capacity Europe in London on October 13, 2026, Datta didn’t pull punches, accusing the competition watchdog of building its provisional case against nexfibre’s proposed £2 billion acquisition of Netomnia on assumptions entirely "divorced from financial reality."
The fiery address brings the brewing tensions between the UK’s alternative network ("altnet") builders and its chief economic regulator to a boiling point. Coming a mere 11 days after the CMA provisionally blocked or flagged the blockbuster transaction for undermining wholesale competition, and just ahead of critical regulatory deadlines, Datta’s remarks highlight a fundamental ideological chasm over the future shape, sustainability, and competitive landscape of Britain’s digital infrastructure.
Executive Overview
At the heart of the controversy is nexfibre’s strategic intent to acquire Netomnia in a multi-billion-pound deal designed to create a heavyweight national challenger to BT’s Openreach. However, the CMA’s interim findings suggest the merger would dangerously compress the emerging altnet landscape, shrinking regions with three competing wholesale infrastructure networks from roughly 32% of the combined Virgin Media O2 (VMO2)/nexfibre footprint down to just 18%.
Datta used his keynote platform to dismantle the regulator’s foundational assumptions. He argued that the CMA has relied on a deeply flawed "counterfactual"—the hypothetical scenario in which rival altnet CityFibre would have successfully acquired Netomnia’s parent company, Substantial Group. Labeling the CMA’s financial math as the "money grows on trees" theorem, Datta turned the tables on CityFibre, accusing the rival firm of severe financial stress, while simultaneously warning that a market predicated on sustaining three nationwide physical fiber infrastructures is nothing short of a "pipe dream."
As the clock ticks toward the CMA’s December 15 final decision deadline, the debate over nexfibre and Netomnia has transcended a simple corporate buyout. It has become a referendum on whether market consolidation is an urgent necessity to save the UK’s altnet sector, or a slippery slope toward reduced consumer choice and oligopolistic dominance.
Detailed Chronology of the Regulatory Clash
To fully understand the gravity of Rajiv Datta’s Capacity Europe address, one must trace the rapid-fire sequence of regulatory and corporate milestones that have defined the autumn of 2026 in the UK telecoms landscape:
- February 2026: Early rumblings of consolidation surface as market pressures mount on smaller altnets. CityFibre CEO Simon Holden publicly raises alarms over prospective market overlap, setting the stage for bitter turf wars.
- Throughout 2025–2026: A competitive sale process for Netomnia’s parent, Substantial Group, takes place. CityFibre bids for the company but fails to secure a deal, paving the way for nexfibre’s subsequent £2 billion acquisition proposal.
- October 2, 2026: The CMA drops its provisional findings on the nexfibre-Netomnia merger. The regulator concludes that the transaction may significantly harm UK wholesale broadband competition, primarily by eliminating the head-to-head pressure that a CityFibre-Netomnia combination would have allegedly introduced.
- Early October 2026: In a parallel move that draws accusations of regulatory whiplash, BT announces its acquisition of TalkTalk out of administration for approximately £400 million. The UK government swiftly issues a Public Interest Intervention Notice (PIIN), mandating a separate CMA probe.
- October 13, 2026: Rajiv Datta takes to the stage at Capacity Europe 2026, launching a broadside attack against the CMA’s interim report, questioning CityFibre’s solvency, and challenging the baseline economic models used by the regulator.
- October 16, 2026: The strict deadline for merging parties to submit formal responses and propose initial remedies to the CMA’s provisional findings.
- October 23, 2026: The final deadline for broader industry stakeholders and interested third parties to submit commentary on the CMA’s interim report.
- December 15, 2026: The statutory deadline for the CMA to issue its final, binding decision on whether to clear, modify, or block the nexfibre-Netomnia transaction.
Dissecting the Counterfactual and the "Pipe Dream" of Three Networks
The core of the CMA’s provisional case rests on a delicate economic counterfactual. The regulator assumes that if nexfibre had not stepped in with its bid, CityFibre would have successfully acquired Substantial Group (Netomnia’s parent company). Under this theoretical roadmap, the UK would enjoy three independent wholesale infrastructure providers—Openreach, VMO2/nexfibre, and CityFibre—competing fiercely across roughly 32% of the VMO2/nexfibre footprint.
Datta categorically rejected this premise during his keynote. "This counterfactual has already occurred," he stated bluntly, reminding the audience that CityFibre had already attempted and failed to acquire Substantial during the 2025 sale process.
Furthermore, Datta criticized the CMA for making sweeping assumptions regarding capital availability. He lambasted the regulator’s view that CityFibre could easily fund such a high-stakes acquisition, and that Virgin Media O2 would perpetually fund endless cable network upgrades regardless of ballooning costs. He dubbed these assumptions the "money grows on trees" theorem, arguing they ignore the harsh realities of debt markets, capital expenditures, and interest rate environments.
The Myth of Openreach’s Contained Footprint
Beyond the counterfactual, Datta took aim at how the CMA characterizes BT Openreach. While the interim report reportedly frames Openreach as a substantial yet contained competitor, Datta asserted that such a description grossly understates reality.
"BT Openreach is the dominant force in FTTH [Fibre to the Home]," Datta emphasized, pointing to Openreach’s massive national footprint of roughly 25 million premises—a number rapidly hurtling toward 30 million. By comparison, nexfibre’s post-acquisition roadmap aims for roughly 8 million premises by the end of 2027, backed by a planned £3.5 billion capital injection.
Datta reiterated his long-held thesis: the UK cannot economically support three independent physical fiber networks running down every single suburban street and rural lane. "There is no economics that works to have three physical networks across every postcode in the UK," he stated. Instead, he painted a realistic picture of a two-network national baseline, with pockets of localized overbuild, arguing that consolidation is not just a commercial preference, but an inescapable economic law of gravity for the altnet industry.
CityFibre in the Crosshairs: Solvency and Capital Structure
Datta’s criticisms did not stop at the regulator’s office; he squarely targeted his primary commercial rival, CityFibre. Painting a grim picture of his competitor’s balance sheet, Datta described CityFibre as "a company that’s in real financial stress."
To back up his claims, Datta pointed to CityFibre’s recent financial reporting, highlighting recurring operational losses, critical material uncertainties flagged by external auditors, and widespread industry reports that the company has been actively seeking a staggering £2 billion debt reduction or restructuring from its lenders.
Unsurprisingly, CityFibre hit back fiercely against Datta’s characterization. In an official statement, a CityFibre spokesperson defended the company’s underlying business health:
"Our performance demonstrates the ongoing, fundamental strength of CityFibre’s business and we are well-positioned to meet any challenges ahead, with substantial funding available and customer numbers continuing to grow across our network."
The spokesperson acknowledged that the company’s capital structure "needs to evolve," but pointed to a massive £900 million equity commitment from its shareholders as proof of robust institutional backing. CityFibre maintained that it is actively engaged with lenders to establish a sustainable long-term financial foundation while preparing for its own strategic M&A drives. Recent corporate updates from CityFibre have indeed shown continued underlying customer, revenue, and EBITDA growth, complicating the narrative around its immediate financial stability.
However, CityFibre’s executive leadership, spearheaded by CEO Simon Holden, has been a vocal opponent of the nexfibre-Netomnia deal since early 2026, warning that the merger would create an excessive 80% network overlap between the participating businesses, thereby crushing localized competition.
When pressed on whether nexfibre would be willing to offer structural or behavioral remedies to appease the CMA, Datta remained measured. While refusing to be definitive on specific concessions, he noted that standard regulatory procedures naturally accommodate remedies and undertakings, provided they do not compromise the viability of the resulting corporate platform. "Anything we consider has to be in the context of a sustainable platform," he stressed.
Regulatory Whiplash: The BT-TalkTalk Contrast
Adding fuel to the fire, Datta highlighted a glaring double standard in how the UK’s regulatory bodies are handling major telecom consolidation events. He drew a sharp contrast between the CMA’s aggressive skepticism toward the nexfibre-Netomnia deal and the regulatory treatment of BT’s acquisition of TalkTalk out of administration for roughly £400 million earlier in October 2026.
While the government felt compelled to issue a Public Interest Intervention Notice (PIIN) regarding the BT-TalkTalk tie-up—given that TalkTalk historically operated as the third-largest buyer of wholesale access—altnet players feel the overarching regulatory posture remains heavily skewed in favor of the incumbent giant. Datta noted that these divergent approaches have left "a lot of people with whiplash" regarding which direction the nation’s regulators are truly steering the digital economy.
The Broader Altnet Crisis: "Lights Have Been Flashing Red"
Datta’s broader warning at Capacity Europe touched upon a malaise affecting the entire UK alternative network ecosystem. For years, private equity and institutional investors poured billions into the "altnet rush," funding dozens of overlapping overbuild operations. However, rising interest rates, inflationary construction pressures, and slower-than-expected retail conversion rates have turned the tide.
"The lights have been flashing red for a year," Datta warned, pointing to a wave of quiet corporate restructurings, covenant waivers, and lender haircuts across the altnet market. He warned that investor confidence is eroding, with many backers openly questioning whether the UK fiber market can deliver a sustainable return on capital under its current hyper-fragmented state.
According to nexfibre, the proposed Netomnia acquisition is not a contraction of healthy competition from three players down to two, but rather a vital evolution that transitions the market from a fragmented collection of fragile balance sheets to two scaled, resilient wholesale platforms capable of going toe-to-toe with Openreach.
Furthermore, Datta urged industry stakeholders to look beyond the immediate build cycle. As fiber architectures evolve past XGS-PON toward next-generation technologies, only a well-capitalized, scaled challenger will possess the financial muscle to fund future infrastructure upgrades independently of BT.
Future Outlook: What Lies Ahead
As the UK telecommunications sector awaits the CMA’s ultimate verdict, the stakes could not be higher.
With the industry feedback window closing on October 23, 2026, and the definitive CMA ruling scheduled for December 15, 2026, all eyes are locked on the regulator. Will the CMA double down on its provisional findings, forcing nexfibre and Netomnia to walk away or offer heavy structural remedies? Or will the compelling arguments regarding altnet sustainability, mounting financial pressures, and the unyielding dominance of BT Openreach sway the panel?
One reality is clear: the era of unchecked, high-risk overbuild in the UK fiber market is drawing to a close. Whether led by a combined nexfibre-Netomnia entity or through CityFibre’s newly funded consolidation push, the British digital infrastructure landscape is bracing for a profound structural realignment. Rajiv Datta has cast down the gauntlet; now, it is up to the regulators to decide whether their vision aligns with economic reality or remains, in his words, a pipe dream.
