Optimum’s CEO says broadband and mobile convergence momentum continues to build

The cable MSO is finding that competitive pricing and the ability to purchase service bundles are becoming key to customer retention.  

One of the key promotions it launched during the quarter was its UnBig Your Bill campaign, a retail promotion that enables AT&T and Verizon customers to lower their monthly mobile costs. Customers who bring their current phone bill to an Optimum store will have their team complete a price comparison; if they can't save the customer money, Optimum Mobile will provide a $150 gift card.

Mathew said its mobile growth is supported by continued improvement in its go-to-market execution, “including stronger sales quality, better experience, more competitive offers with everyday low pricing and discounts on broadband and a focus on multiline adoption, all of which are driving higher value customer additions.”

He added that “this is reinforced by our recently launched UnBIG Your Bill campaign, which highlights meaningful annual savings compared to the major carriers.”

Convergence base deepens

Optimum’s strategy to target its broadband customers with mobile services continues to bear fruit, with penetration rising nearly 9% in the first quarter.

This comes as Optimum continued to enhance its base of mobile subscribers.

During the quarter, Optimum added 52,000 net mobile lines, which the company said was its strongest quarterly performance in six years, bringing the total to 674,000.

Likewise, residential mobile service revenue grew 35% year over year to $50 million in Q1 2026, compared to $37 million in the first quarter of 2026.

Mathew said the service provider sees a significant opportunity to deepen its mobile bond with existing broadband customers.

“While we have steadily grown convergence in our base, we still see significant runway to continue to drive mobile attachment and deepen penetration among existing customers,” he said. “More broadly, our entry offer plus attach model is central to our strategy and how we go to market. Every new broadband customer is an opportunity to deepen the relationship and attach mobile, video, Whole Home WiFi, Total Care, or other value-added services. This approach allows us to balance more competitive entry pricing with stronger lifetime value.”

Convergence ARPU grew 1.2% year-over-year to $79.32.

The service provider’s convergence ARPU is calculated by dividing the average monthly revenue from broadband and mobile services by the average number of residential broadband relationships, excluding mobile-only customers.

Marc Sirota, CFO of Optimum, said the company expects convergence ARPU to become a key metric for evaluating the business.

“We will continue to balance rate and volume throughout the course of the year as we push to improve the underlying trends on broadband customer results. We do anticipate pressure on ARPU in the full year, particularly from broadband growth additions as we focus on prioritizing volume stabilization and multiproduct penetration,” he said. “We believe this shift will ultimately drive stronger attach and improve the overall value of the customer relationship, supporting more durable revenue and ARPU growth over time.”

Fiber migration continues

In addition to scaling mobile, Optimum continues to expand its fiber-to-the-home (FTTH) network reach. Over the past three years, it has expanded its network by over 500,000 homes passed.

We remain focused on building fiber, selling fiber and continuing to migrate customers organically within our base, having expanded our network by over 500,000 homes over the past three years.

Optimum added 38,000 total new passings in the first quarter and +190k total new passings in the last twelve months. On these fiber networks, about 96% of the total footprint has 1 Gbps or higher speeds available

It also continues to ramp up its fiber customer base, adding 13,000 fiber customers in the quarter, bringing its total to 729,000, up over 20% year-over-year.

A key focus for Optimum is bringing on customers in new communities where it is building fiber, rather than migrating existing HFC customers to fiber.  

“While fiber migration remains an important part of our long-term road map, we are currently prioritizing new builds and new broadband customer trends over migrations of existing customers to fiber,” Mathew said. “Over time, we expect to re-engage more proactively to transition customers to fiber. But in the current environment, we are focused on investing where we see the highest near-term returns and greatest impact on long-term value creation.”

Broadband struggles, opportunities

During the first quarter, Optimum struggled with broadband, losing 64,000 customers, or 56,000 excluding a subscriber adjustment related to prior periods.

The service provider ended the quarter with 4.1 million broadband subscribers.

Despite the losses, Optimum is seeing more of its broadband customer base migrate to higher-speed tiers, with 47% of the base taking 1 Gbps or higher speeds at the end of the first quarter of 2026, up from 21% in the first quarter of 2023.

A big contributor to its broadband troubles in the first quarter was a rise in fixed wireless access (FWA) and fiber overbuilders offering a host of new pricing and subscriber perks, such as fixed pricing.  

“Across our footprint, ILECs, fixed wireless providers, and fiber overbuilders all continue to lean aggressively into lower entry pricing, extended price locks, and promotional incentives,” Mathew said. “In the West, in particular, the competitive profile has shifted considerably with the expansion of fixed wireless availability as well as fiber overbuilders further intensifying market dynamics in an already challenging landscape. This is the backdrop against which we are executing.”

He added that “Our response has been to simplify and establish a more consistent and competitive product and pricing structure across our footprint.”

Optimum reported that total first-quarter revenue was $2.07 billion, down 4% year over year, with residential revenue down 6.5% year over year to $1.56 billion.
