ExxonMobil Corporate Plan Update Q&A


This abridged transcript presents questions related to ExxonMobil’s announced Pioneer acquisition
during ExxonMobil’s Corporate Plan Update call held on December 6, 2023.





Sam Margolin: Hi. Good morning. Thanks for taking the question. I appreciate the fact that the numbers today are all pre-Pioneer. But Pioneer does have an impact which materially changes the mix of your capital towards Permian and short cycle. And you mentioned that you already have sort of a higher than normal amount of flex in capex built in from low carbon. Theoretically, more mix towards Permian will also increase the flex. So how do you think about a post Pioneer capex range in terms of widths out to 2027 after the close and then, I mean, how do you think about decision making with flex in the Permian, because, when you flex long-cycle projects, you push out schedule when you flex long cycle projects, you push out schedule, but you might not have an impact on near-term declines. But in lower 48, if you look at activity, you know, you have to deal with declines. So how do you handle all those variables, you know, in a post Pioneer world? Thank you.


Darren Woods: Yeah, sure. I'll take a crack at that and then see if Kathy wants to add anything to it. I think at this stage, we've given what I would say is a very high-level perspective of how to think about capital going forward, with the understanding that Pioneer has got a very capable organization, I think looks at the development of its production profile in a very consistent manner that Exxon Mobil does, which is a focus first on value.


And so, our going in assumption was given their focus on capturing value versus growing volumes, that their plan would be consistent with the plan that we would develop. And that's absent of the work that we plan to do as we bring the two organizations together and figure out what the best of both looks like.

And I would say that is truly our objective set, to bring the best thinking of the Pioneer folks and the techniques and abilities that they have with the best thinking of our folks. Get together and figure out what is the optimum development program, and we just haven't done that yet, Sam, and won't do that until we get together.


And so it's really hard for me to tell you what we think about going forward. What I would say is that the decision variables are not going to change, which is, it comes back to making sure that we're doing it very efficiently, that we're maintaining our advantage versus the rest of industry and in fact growing that advantage and, in that, what we're doing is creating value and there's no -- we're not destroying value or mitigating value.


And so that's going to be the primary focus is what we're doing, the value proposition and that’ll all get thrown into the mix and then we'll come out with a discussion around how we see that playing out. My view is that we do have a lot more flexibility, but we're going to use the flexibility to maximize the value of the combined entity.


Our intent is once we get through the close and we know there's a lot of interest in this space, understandably, that we would come out with a spotlight and update this plan with the thinking that we've done collectively with the Pioneer folks and help the investment community understand exactly how we plan to go forward there. Anything to add to that, Kathy?


Kathy Mikells: The only thing I'd add is when you think about flexibility, this is pretty low-cost supply. And so this is cost of supply, kind of $35 or lower per barrel. And so, yes, it's there to be flex, but you have to get to a pretty soft environment before it necessarily makes a lot of sense to flex down much. So, it does provide us with more flexibility. We've said short cycle as part of the upstream portfolio will go up to about 40% once we close the Pioneer transaction but that flexibility will be there, but we won't necessarily be planning in the base case for that flexibility.

Darren Woods: I think the only thing to add on that, Sam, is, you know, Pioneer pays for itself. So, it doesn't force us to make decisions that we don't feel are the optimum. We've got, in my mind, given the cash and cash flow that comes with Pioneer, we've got the optionality to figure out what is truly optimum and then build a plan based on that optimum and not have it constrained by some factor that dis-optimizes what we ultimately want to do there. So, we feel really good about the platform that we have there. And the question is, what is that? How does that translate into operating plans? Like I say, we'll share that with you once we've got it.


Darren Woods: And then maybe I would add, just because nobody has brought this up so far today, we obviously announced as part of the corporate plan that we intend to increase the pace of our share repurchase program once we close Pioneer.


So, as everybody knows, we've been on a pace of $17.5 billion in share repurchases annually. We will get that done this year. But post-closing Pioneer, we would expect that go forward pace to increase to $20 billion annually.

Actions needed to advance the Company’s 2030 and 2035 greenhouse gas emission-reductions plans are incorporated into its medium-term business plans, which are updated annually. The reference case for planning beyond 2030 is based on the Company’s Energy Outlook research and publication (the “Outlook”). The Outlook is reflective of the existing global policy environment, the Outlook does not attempt to project the degree of required future policy and technology advancement and deployment for the world, or the Company, to meet net zero by 2050. As future policies and technology advancements emerge, they will be incorporated into the Outlook, and the Company’s business plans will be updated accordingly. Actual future results, including the achievement of net zero in Upstream Permian Basin unconventional operated assets by 2030/2035 and plans to lower methane emissions from operated assets, to increase water recycling in our combined Permian operations, and to feed hydrogen, ammonia, and carbon capture projects could vary depending on the ability to execute operational objectives on a timely and successful basis; policy support for emission-reduction products and technologies; changes in laws, regulations and international treaties regarding lower emission technologies and projects; government incentives; unforeseen technical or operational difficulties; the outcome of research efforts and future technology developments, including the ability to scale projects, technologies, and markets on a commercially competitive basis; changes in supply and demand and other market factors affecting future prices of oil, gas, and petrochemical products; the actions of competitors; and other factors discussed in this communication and in the additional forward looking statement disclaimer included above.
