Summary

  • AT&T has agreed to put its acquired Forged Fiber 37 platform and existing Gigapower wholesale venture into a new vehicle with GIP and CPP Investments; closing is expected in the first half of 2027, not completed.
  • AT&T would retain 50% and GIP plus CPP collectively hold 50%. AT&T expects not to consolidate the venture after closing, but the public announcement gives no valuation, cash proceeds, investor-by-investor split, governance detail or future capital-call formula.

AT&T’s fiber announcement is easy to misread as a simple expansion deal. It is also a proposed change in the boundary between owned infrastructure, outside capital and reported earnings. The company says it will combine Forged Fiber 37—the subsidiary holding the mass-market fiber assets and operations acquired from Lumen—with Gigapower, its existing wholesale-fiber joint venture with Global Infrastructure Partners (GIP). Canada Pension Plan Investment Board (CPP Investments) would join GIP as an investor in the new U.S. venture.

The ownership headline is precise only at one level: AT&T would own 50%, while GIP and CPP Investments together would own the other 50%. Their individual shares are not disclosed. Nor does the announcement state an enterprise value, cash consideration, proceeds amount, debt contribution, board rights or how future construction capital would be divided. This matters because Forged Fiber 37 began as a wholly owned platform, whereas Gigapower already had an outside partner. Combining the two is not the same as selling a stated percentage of one clean, newly built asset pool.

The reporting boundary changes after closing

The timing separates two accounting states. Until close, expected in the first half of 2027 and subject to customary conditions and regulatory approvals, AT&T expects Forged Fiber 37 to remain classified as held for sale and discontinued operations. It says the unit’s results and direct cash flows will stay outside continuing operations. After close, AT&T does not expect to consolidate the new venture’s financial results; it plans to record its share of equity income or loss in earnings, including adjusted EPS from continuing operations.

That is consequential without being a verdict on the economics. A line-by-line subsidiary can reveal revenue, operating cost and capital spending in a way that an equity-method investment does not. The new presentation may make AT&T’s continuing business look less capital-intensive, but it will also make the venture’s standalone operating performance less visible in AT&T’s consolidated statements. Investors will need separate JV disclosures to assess returns and build productivity.

AT&T says it expects proceeds at closing and may use them for several priorities: moving toward a net-debt-to-adjusted-EBITDA ratio around 2.5x within about three years, continued investment and shareholder returns. It supplies neither the amount nor a fixed allocation among them. A debt target is therefore an intended use, not evidence of the proceeds’ size or the venture’s valuation.

Reach is not the same as choice

At closing, the JV is expected to have nearly 5 million fiber locations and serve more than 1 million AT&T fiber subscribers across 16 states. These are forecasts for a future closing date. A location passed is not a subscriber, a retail-ready address or proof that multiple internet providers can buy wholesale access there. “Commercial open access” describes the intended platform, not the terms or availability at each address.

AT&T’s end-2030 goal is to reach more than 60 million consumer and business locations with fiber. The company expects about 50 million through its owned-and-operated network; the broader target also includes Forged Fiber 37, Gigapower and other commercial open-access providers. The difference cannot be assigned to this JV alone. Its contribution depends on closing, construction, address qualification, wholesale arrangements and take-up—none quantified in the announcement.

The deal’s test is consequently not the announced footprint by itself. It is whether a shared vehicle can finance incremental builds, secure customers beyond AT&T’s retail base and provide returns that compensate outside capital—while preserving useful operational and service accountability. Those outcomes remain prospective.
