This is a blog about uncertainty because it’s hard to know what else to say about the impact of tariffs on the broadband industry – other than we know there will be an impact. Right now, the tariff situation is in utter turmoil. Every ISP I talked to about the issue had the same concerns. They are all hoping for certainty. They can deal with price increases, but they can’t deal with not knowing the situation for building a year from now.
ISPs generally plan a year ahead. The networks they are building now were planned in 2024, and many ISPs are paralyzed about what to plan for 2025. I’ve been through other periods of economic uncertainty during my career, and every time, the most common reaction to uncertainty from ISPs has been to take a pause until the uncertainty ended. If the tariff situation doesn’t soon become predictable, I would expect 2025 construction to slow significantly, particularly for smaller ISPs.
The first place I would normally go to get a feel about the impact of any big changes for the whole industry is to see what big ISPs have to say about it. The big ISPs have quarterly earnings calls, and Wall Street expects them to talk about expected changes in their company in the next quarter and next year. I listened to the recent earnings calls for Comcast, Charter, and T-Mobile, and the companies were all coy and noncommittal on the tariff topic.
Perhaps the easiest way to think about tariffs is by industry segment. I’ve been thinking about what will happen if tariffs settle in at something like the original announcement of 10% tariffs across the board.
Fiber ISPs would probably have the smallest impact of tariffs – but it’s not zero. Fiber is made domestically. Fiber electronics will be shielded from tariffs to some extent since the major electronics vendors established US manufacturing to prepare for BEAD grants. But those factories still rely on some imported components. Perhaps the biggest impact will come for non-grant construction since those ISPs have continued to buy cheaper imported electronics. It will be interesting to see if the new U.S. factories can supply everybody. I suspect they can’t. But even if they can, U.S. electronics are more expensive than the imported electronics before tariffs.
Cable companies are not going to be so lucky. Companies like CommScope and Vecima Networks that make cable electronics have already said they will have big hits from tariffs. We’ll have to see if this results in a slowdown of upgrades of cable networks to DOCSIS 4.0 or mid-splits. Day-to-day components like settop boxes are mostly manufactured overseas.
WISPs and cellular carriers are likely to see a hit from tariffs since most of their electronics are imported. There are American makers of towers and related equipment. Cellphone prices would increase from tariffs, but for now those tariffs have been reversed.
All ISPs are going to see a hit on WiFi gear, which is almost all imported.
ISPs and carriers buy a lot of vehicles, and it looks like the cost of new vehicles will be climbing.
The surprising increases are going to come on the little stuff like the small hardware needed for all kinds of network construction. The worry is not just that those prices might climb, but that there will be supply chain interruptions.
Any ISP that is building a network funded by grant dollars has to be worried since grants awarded in past years will not be increased, and the ISP will have to absorb the full impact of tariff increases. I have to wonder if this will put more pressure on defaults for RDOF and other previous grants if ISPs see grant projects becoming unviable. I won’t be shocked if some of the companies winning BEAD grants change their mind by the time they are asked to sign a grant contract later this year.
The bottom line is that uncertainty is not good for the industry, and I think the reactions we’ll be seeing from ISPs will be more a reaction to uncertainty than to cost increases.
