Talen’s Q4 saw revenue growth accelerate to more than 60% YoY as it is now recognizing the impacts of the 2025/26 capacity auction price increase, though margins and EPS were both impacted by a rather large, one-time $501 million charge related to stock awards.
On the broader view of the grid and power ecosystem, Talen noted that PJM’s grid is seeing strong peak load growth forecasts, such as 15GW of forecasted incremental load additions by 2030 in Ohio and Indiana, and 10GW of load under agreement in Pennsylvania by Q1 with half under construction. However, Talen revealed that regardless of if/when they sign another data center deal – whether it is tomorrow or later in 2026 – they would not be delivering or ramping until 2028.
Strong Peak Load Growth Forecasts
Talen provided some statistics on peak load growth forecasts within PJM’s footprint, noting that AEP (Ohio and Indiana) is forecasting 15GW of incremental load by 2030 with 90% under energy/electric service agreements (ESA), while PPL (Pennsylvania) is expecting to have 10GW load under ESA by the end of Q1 with 5GW under construction. Over the long-term, PPL has signed agreements with data centers to bring 25GW online through 2034.
Management says that these strong load growth signals mean “higher runtimes for our existing generation fleet, especially our intermediate dispatch and peaking units,” as well as more attractive economics for offtake agreements, both beneficial for revenue growth over the next few years.
More specifically, analysts questioned about the 10GW load PPL is expecting to have under ESA, with Talen saying the ESAs are a strong leading indicator for PPAs/ data center demand following through:
“I’m just trying to link the comments that we’re hearing from PPL and AEP to your generation contracting. For example, the comment that you quoted yourself, right? In the slides, that PPL expects 10 gigs of load under ESAs by the end of the first quarter, which sounds like one more month. How does that relate to, you know, you being the largest generation company in the PPL zone and signing, you know, generation contracts to back this 10 gigs of load?”
CFO Cole Muller:
“Without an ESA, data centers aren’t going to contract under a PPA, right? I think that’s just a good kind of leading indicator of PPAs coming. Just to be really clear, we obviously have announced 2 gigawatts, roughly, of tangible PPA in that zone. I mean, again, leave it to PPL to break down their count, but, you know, that’s 2 of the 10 right there.”
Montour Data Center Pushback, 2028 Data Center Delivery Timeline
Talen and Amazon recently faced substantial pushback from local regulators to the proposed rezoning of agricultural land to data center use, with the rezoning request denied on concerns over higher local utility prices. Talen hinted in the opening remarks that it will remain flexible and can pivot to a different solution as needed, seeing it as being similar to the initial regulatory decisions regarding AWS and Susquehanna’s behind-the-meter pact.
While the regulatory process is still ongoing, Talen revealed in the Q&A related to its long-term FCF projection that any data center PPAs — regardless of it being at Montour or at other sites (what they dub a ‘virtual’ PPA where power is delivered to a data center not co-located nearby) — will not see megawatts being delivered until 2028:
“I said we won’t discuss Montour, but maybe we’ll unpack it a little bit for you. But the 1 gigawatt data center PPA is really more than likely a post 2028. Because when you think about when you’ve got to build data centers like’s going on at Susquehanna, there’d be a ramp rate. That’s why we show that out there on 2028.
That [FCF upside lever is] probably the least likely to be pulled forward early, because even if there was a signed contract today on the so-called Montour deal or some other virtual PPA, across our pipelines of opportunity, the delivery of those megawatts is not gonna be 2028. This is something that I find very interesting going back to the Montour. Whether Montour happens today or happens 6 months from now, it really is irrelevant to when the megawatts would flow under that type of arrangement, because they’re not going to be delivered until 2028, and they’re gonna ramp up from there more than likely.”
The biggest takeaway here is that the emphasis may remain on time-to-power and providers such as Bloom Energy, for data centers able and wanting to come online within the next 12 to 24 months, as Talen is saying it will not be able to ramp to GW-scale PPAs until 2028 at the earliest.
Cornerstone Acquisition Boosts Fleet to 15.6GW
Talen is continuing to increase its fleet, now entering into a definitive agreement with ECP to purchase three assets – the the 875 MW Waterford and 456 MW Darby assets in Ohio, and the 1.12 GW Lawrenceburg asset in Indiana. Talen believes these high-capacity factor assets will have high free cash flow conversion rates and enhance its large-load contracting opportunities. In total, once closed, the three assets will boost Talen’s fleet to nearly 15.6GW, up from its current 13.1GW.
The Cornerstone acquisition is priced at $3.45 billion, including $2.55 billion in cash, which will be funded by debt, and 2.4 million shares of stock valued at $900 million at the time of signing. The transaction is expected to close early in 2H 2026. For some of the financial impacts, Talen expects the Cornerstone fleet to generate more than $4 in incremental annual FCF upon closing, with this broadly expected by 2027 in full, with potential for upside in 2026 should the transaction close in the summer. For adjusted EBITDA, Cornerstone was implied to have a ~$500 million annual impact post-close.
On why they continue to acquire assets in the western PJM area, management explained that the region has “significant data center tailwinds and accessibility to reliable, low-cost natural gas from the Marcellus and Utica shales,” providing Talen with access to a larger, faster growing pipeline of potential data center offtakers with lower-cost fuel possibly aiding better margins in future deals.
Related to expanding its fleet and footprint, management did state that they have “numerous other organic and inorganic sites we are developing across the PJM footprint,” but emphasized that they will “not discuss them at any level of detail, and we no longer plan to discuss development in the public forum” to avoid pushback such as what is currently occurring with Montour.
New Build vs Existing Builds
On this point of acquiring existing , Talen made an interesting case that it will be existing generation capacity, not new generation capacity, that will be the first to serve new data center loads:
“Over time, we’ll start to shift to kind of hybrid models where there’s existing gen powering the first three to five-year build-out of these data centers across Pennsylvania, Ohio, Indiana and so forth. Eventually, backed by a second either upscaling of a PPA or a second PPA that, you know, enables new generation to kind of fill the gap from there.” Management also emphasized that they believe that there is not much new generation that will be able to meet data center demands in 2027 through 2029.
CEO Mac McFarland provided more clarity on the new vs existing generation debate in a later question about peers turning to new-build gas or turbines, and if Talen would follow and secure the supply chain to do something similar (as turbines are sold out for 24+ months):
“With respect to turbines and EPC relationships and the rest of it, our view and the reason why we’ve built up and invested in these existing assets is very much to the point which we think that there’s still the capability to use existing assets to contract. There’s a lot of data centers that are out there right now that are looking at whether they contract for a longer period of time. Existing ones, right? You saw that in a recent PPA announcement with existing data center load.
I think that when it comes to new build, and there’s a fair amount of discussion around new build, we view new build very simply. New build is going to require either winning in the RBP and having a 15-year contract that allows for a taking the merchant risk of the capacity off, thereby allowing financing, or new build is going to require a contract.”
This piece highlights the two main reasons why Talen is quick to take on debt and quick to acquire these existing generation assets – in the case of Guernsey and Freedom, management believed it was cheaper to acquire than to build new CCGT plants, and secondly, management expects existing gen to serve data center loads first, making their fleet potentially more attractive for possible data center offtakers.
There are other hurdles to new builds related to the RBP (discussed below) that would likely put new build capacity towards meeting shortfalls rather than having optionality to serve data center loads. However, Talen did not write off new builds completely, saying that they would be open to new gen with the right certainty and the right deal (such as that 15-year deal that would effectively finance the build).
Quick Note on PJM’s Reliability Backstop Procurement
PJM is currently proposing the Reliability Backstop Procurement (RBP) as a one-time procurement of capacity to address the ‘unprecedented’ load growth the grid is seeing. PJM said last week that its “current projections show a potential capacity shortfall of 50-60GW in the next decade primarily driven by large load growth but also forecasted conventional load growth,” and as such, it needs to add net-new supply to have enough capacity in the region to meet peak demand. The RBP aims to ‘markedly improve’ capacity and minimize future shortfalls.
On the topic of the RBP, policy uncertainty within PJM and contracting abilities, management explained that contract details, who pays for energy and how capacity is allocated will work out in due course, and that ultimately, data centers are coming and are not slowing down. CEO Mac McFarland explained that hyperscalers and chip manufacturers “continue to talk about the race for creating data centers on the ground, powering them today, powering them in 2028, and then soon 2029 will become the new 2028. I think that as we progress through that, it just further aids in the ability to continue those discussions. We don’t see any slowdown to it, and we think that the RBP will ultimately increase the level of those discussions.”
Financials
Revenue up 60% YoY in Q4, to Accelerate into Q1
Talen reported Q4 revenue of $749 million, up 60.4% YoY but down (7.8%) QoQ. This was driven by nearly 257% YoY and 9.6% QoQ growth in Capacity revenue to $182 million as the 2025-26 PJM capacity pricing of $270/MW-day kicks in. Energy and other revenue was $589 million, up 34.8% YoY but down (2.5%) QoQ. Talen also recorded a ($22 million) loss on hedging derivates this quarter.
Talen did not provide guidance for Q1, though revenue is currently projected to be $1.12 billion, up 187.2% YoY and 49.5% QoQ. This would mark a sharp acceleration on both a YoY and QoQ basis, of 127 points and ~40 points respectively.
For 2025, operating revenue was $2.58 billion, up 22% YoY, driven by a 13.8% increase in Energy and other revenue to $2.14 billion and a 152.6% increase in Capacity revenue to $485 million.
Talen did not provide formal guidance for FY26 this quarter, though it has previously provided estimates for 2026 revenue at its Investor Day in September. Talen had forecast Energy revenue to be $2.885 billion, up 34.8% YoY, and Capacity revenue to be $953 million, up 96.5% YoY; this would give visibility to roughly $3.84 billion in revenue excluding hedging impacts. However, current consensus estimates for FY26 are much higher at $4.21 billion, for growth of 63.1% YoY.
Margins Impacted by Stock Award Related Charge
Talen’s operating and net margins were deep in the red in Q4 as the company recognized a $501 million charge related to accounting changes for certain stock awards granted in 2023; however, excluding this impact, margins were solid and down roughly 7 points QoQ.
GAAP gross margin was 61.7%, down 3.2 points YoY and 2.3 points QoQ.
GAAP operating margin was (41.8%), and when excluding the one-time stock award charge, operating margin would be 25.1%. This compares to 32.5% in Q3 and 3.4% in the year ago quarter.
GAAP net margin was (48.5%), and when excluding the stock award charge, net margin would be 18.4%. This compares to a 25.5% margin in Q3 and a 17.6% margin in the year ago quarter.
For FY25, GAAP gross margin was $1.52 billion for a 58.7% margin, down 3.6 points YoY.
GAAP operating margin was (3.5%), and excluding the stock award charge, operating margin would be 15.9%; this compares to a 10.7% margin in 2024.
GAAP net margin was (8.5%), and excluding the stock award charge, net margin would be 10.9%, compared to a 47.2% margin in 2024 as Talen benefited from gains on the sale of its Cumulus data center assets to Amazon in March 2024.
Looking ahead to 2026 (and 2027), Talen provided a quick snapshot of margin impacts from its hedging program, which uses derivates to hedge against rising gas prices. For a +/- $10 MWh increase from the end of 2025, Talen is guiding for a +/-$105 million impact to margins, or around 2.5 points at the current revenue estimate. Management added that hedging will be less of a necessity as the AWS deal ramps and as cash flows increase.
EPS and Adjusted EBITDA
Due to the stock award charge, Talen reported a large loss in Q4 at ($7.75) per share. This also drove FY25 GAAP EPS to a loss of ($4.79); excluding the impact of the charge, Q4 EPS would be ~$3.21, and FY25 EPS would be ~$6.17.
Looking ahead to FY26, GAAP EPS is projected to be $20.98, nearly tripling the stock-award adjusted figure implied from above.
Turning to adjusted EBITDA, Talen reported a strong 51% margin in Q4 with adjusted EBITDA of $382 million. This marked a 15.9 point YoY and 6.3 point QoQ expansion, with Talen noting the strong YoY growth was due to higher capacity prices and the AWS ramp, among other factors. For FY25, adjusted EBITDA was $1.04 billion for a 40.1% margin, up 3.7 points YoY.
Talen maintained its FY26 adjusted EBITDA guidance of $1.75 to $2.05 billion, noting that this excludes its pending acquisition of the Cornerstone assets, expected to close in 2H. This would represent growth of 83.6% YoY, and represent a ~45.1% margin at the midpoint of guidance and at the current $4.21 billion consensus estimate.
Cash Flows and Balance Sheet
Talen’s debt load is quickly increasing as the company continues to take on debt for its acquisitions, though it expects to quickly deleverage through 2026.
Operating cash flow was $280 million for a 37.4% margin, up 35.3 points YoY but down 6.8 points QoQ. For FY25, operating cash flow was $704 million for a 27.3% margin, up 15.2 points YoY.
Adjusted free cash flow was $292 million in Q4 for a 39% margin, up 34.5 points YoY and 11.5 points QoQ. For FY25, adjusted FCF was $524 million, at the upper end of guidance for $450-540 million and representing a 20.3% margin, up 6.9 points YoY. Talen also maintained its FY26 adjusted FCF guidance of $980 million to $1.18 billion, more than doubling YoY at the midpoint of $1.08 billion.
Cash, equivalents and restricted cash totaled $752 million in Q4, with total liquidity of more than $2 billion. Debt rose sharply to $6.81 billion, up from $3.03 billion in Q3 as Talen took on ~$3.89 billion in debt to fund its Freedom and Guernsey acquisitions. Talen is expected to take on another $2.55 billion in debt to fund the Cornerstone acquisition.
Management stated that net leverage ratio for 2025 would be an ‘apples-to-oranges’ comparison as it would include the debt related to the Freedom and Guernsey acquisitions but not the EBITDA, and instead projected 2026 net leverage to be <3X, based on current net debt of $5.75 billion and adjusted EBITDA guidance for $1.9 billion. Management added that they still expect to have net leverage of <3.5X by year-end even when incorporating the debt added by Cornerstone.
Conclusion
Talen reported strong revenue growth in Q4 at 60.4% YoY with Q1 expected to accelerate to 187.2% as the new capacity pricing kicks in. Adjusted EBITDA and adjusted FCF are both projected to increase sharply in 2026, with EBITDA guided to be up 83.6% YoY and adjusted FCF to more than double at midpoint.
Notably, on the tune of data center load requests and serving this demand from the grid, Talen revealed in a blanket 1GW scenario that it would not be delivering or ramping those megawatts until 2028, putting the near-term emphasis again on time-to-power solutions such as Bloom Energy’s fuel cells.
