The National Telecommunications and Information Administration's supplemental funding round for the $42 billion Broadband Equity, Access, and Deployment (BEAD) program — roughly $21 billion of which remains unallocated — will likely run nine months and may direct more dollars to satellite providers through its averaging-based cost model, former FCC official Carol Mattey said this week.

Mattey, founder of Mattey Consulting, made the remarks on the Fiber Broadband Association's "Fiber for Breakfast" episode aired September 30, in conversation with FBA CEO Gary Bolton.

What does the timeline look like?

NTIA's framework sets a defined state-level sequence:

• 30 days to validate the unserved locations list that NTIA supplies
• 1 week to publish the revised list for a challenge process
• 30-day challenge window for providers
• 30-day window for states to adjudicate challenges
• 90-day supplemental bidding round

The state steps are fixed on paper. NTIA's own review windows are not.

"Realistically, this process could take nine months," Mattey said. "What remains unclear is how long in between each step will NTIA take when the ball's back in their court, whether it's to approve the final list, make a decision as to how much money to allocate, or act on the final supplemental proposals."

She cited NTIA's history of slipping self-imposed dates, including non-deployment guidance originally due in March and then deferred to "this summer."

Where is the non-deployment guidance?

The only BEAD-related NTIA notice released over the just-concluded summer directed remaining funds toward deployment. Mattey believes that document satisfied NTIA's summer pledge and that broader non-deployment guidance — covering adoption, equity, and middle-mile programs — may not arrive until after the supplemental round closes. That sequence would push any non-deployment spending well into 2027.

Mattey has publicly backed using leftover non-deployment dollars for broadband-adoption initiatives rather than additional build-outs.

How does the cost model work, and who benefits?

NTIA calculates each state's supplemental allocation by multiplying the average cost per broadband-serviceable location (BSL) — drawn from that state's fiber, fixed wireless, and satellite winners — by the count of remaining unserved BSLs in that state.

Because satellite bids came in well below terrestrial prices, averaging the three drags state averages downward. That matters because the leftover footprint skews toward the most expensive to serve: remote homes, tribal lands, and rugged terrain where fiber trenching costs climb fast.

"So by averaging all those together, it will bring down the state average for this supplemental round of funding," Mattey said. "Whether that cap will operate as a constraint is one of the things we're going to have to work through."

Does the structure favor satellite?

Mattey expects the round — limited to unserved, not underserved, locations — to produce scattered, non-contiguous service areas that terrestrial builders find uneconomic to bid on. She described the likely footprint bluntly: random locations sprinkled few and far apart, with no logical project areas.

Asked whether the cost cap and narrow scope could steer dollars toward low-Earth-orbit operators, she offered a pointed conclusion: "The cynic in me wonders whether this supplemental round of funding is just really going to end up driving more funding to satellite. ... But we shall see. We shall see."

NTIA's choice to exclude underserved locations further shrinks the addressable pool for fiber and fixed-wireless bidders, who traditionally target those slightly better-served census blocks.

What's next?

If Mattey's nine-month estimate holds, state validation could close by early summer 2026, with the 90-day supplemental bidding window potentially wrapping by late 2026 or early 2027 — though every step that returns the ball to NTIA remains an open variable on the timeline, and a separate challenge process could force additional revisions to each state's final locations list.
