Crescent Energy Co

On October 8, 2026, the Company provided certain updates to potential investors, the relevant excerpts of which are set forth below.

Based on forecasts used in our reserve report and the Devon EF Assets reserve report, our proved developed producing (“PDP”) reserves as of December 31, 2025 have estimated average five-year and ten-year annual decline rates of approximately 12% and approximately 9%, respectively, and an estimated 2026 PDP decline rate of approximately 32%.

Our portfolio of assets:

•at December 31, 2025, consisted of 975.5 net MMBoe (or 1,127.3 net MMBoe after giving effect to the Devon EF Assets Acquisition) of proved reserves, of which approximately 61% were liquids (or 63% after giving effect to the Devon EF Assets Acquisition), reflecting $7.8 billion in standardized measure and $8.6 billion and $7.5 billion, respectively (or $11.0 billion and $8.9 billion,, respectively, after giving effect to the Devon EF Assets Acquisition), in net proved and net proved developed (“PD”) present value discounted at a 10% discount rate;

•during the year ended December 31, 2025, produced 260 net MBoe/d (or 316 MBoe/d after giving effect to the Devon EF Assets Acquisition) and during the six months ended June 30, 2026 produced 338 net MBoe/d (with the Devon EF Assets Acquisition to add production of approximately 71 net MBoe/d); and

•during the year ended December 31, 2025, generated $167.2 million of net income, $1.7 billion of net cash provided by operating activities, $2.1 billion of Adjusted EBITDAX and $856.1 million of Levered Free Cash Flow (or $373.6 million of net loss, $4.1 billion of Adjusted EBITDAX and $0.8 billion of Levered Free Cash Flow after giving effect to the Transactions and the related financing transactions), and during the six months ended June 30, 2026, generated $74.5 million of net income, $1.5 billion of Adjusted EBITDAX and $609.5 million of Levered Free Cash Flow (or $251.8 million of net income, $2.1 billion of Adjusted EBITDAX and $0.8 billion of Levered Free Cash Flow after giving effect to the Devon EF Assets Acquisition and the related financing transactions).

While many of our peers have historically outspent their cash flows, we have averaged a reinvestment rate, which we define as our historical capital expenditures (excluding acquisitions) over a specified period as a percentage of our historical Adjusted EBITDAX for such period, of approximately 45% of Adjusted EBITDAX since 2021.

The table below illustrates the aggregate reserve volumes associated with our proved assets as of December 31, 2025.

(1)Our reserves and present value (discounted at ten percent, or PV-10) were determined using average first-day-of-the-month prices for the prior 12 months in accordance with SEC guidance. For oil and NGL volumes, the average WTI posted price of $65.34 per barrel as of December 31, 2025, was adjusted for items such as gravity, quality, local conditions, gathering, transportation fees and distance from market. For natural gas volumes, the average Henry Hub Index spot price of $3.39 per MMBtu as of December 31, 2025, was similarly adjusted for items such as quality, local conditions, gathering, transportation fees and distance from market. All prices are held constant throughout the lives of the properties. The average adjusted realized product prices over the remaining lives of the properties are $64.42 per barrel of oil, $2.24 per Mcf of natural gas and $19.36 per barrel of NGLs.

(2)Reflects the net PD present values reflected in our and the Devon EF Assets’ respective proved reserve estimates as of December 31, 2025. PV-10 is not a financial measure prepared in accordance with GAAP because it does not include the effects of income taxes on future revenues. Our standardized measure totaled $7.8 billion as of December 31, 2025.

(3)Includes working interests in other basins not listed above; totals may not sum.

(4)The Devon EF Assets’ reserves and PV-10 were determined using SEC pricing. The 12-month 2025 average adjusted prices after differentials were $2.73 per Mcf of natural gas, $63.82 per barrel of oil, and $22.96 per barrel of NGL.

(5)Our NYMEX reserves and PV-10 were determined using index prices for oil and natural gas, respectively, without giving effect to derivative transactions and were calculated based on settlement prices to better reflect the market expectations as of that date, as adjusted for our estimates of quality, transportation fees, and market differentials. The NYMEX reserves calculations are based on NYMEX futures pricing at closing on September 30, 2026 for oil and natural gas. The average adjusted product prices over the remaining lives of the properties are $69.05 per barrel of oil, $2.37 per Mcf of natural gas and $20.42 per barrel of NGLs as of September 30, 2026 for Crescent Energy Company. We believe that the use of forward prices provides investors with additional useful information about our reserves, as the forward prices are based on the market’s forward-looking expectations of oil and natural gas prices as of a certain date, although we caution investors that this information should be viewed as a helpful alternative, not a substitute, for the data presented based on SEC pricing.

(6)The reserves, PV-0 and PV-10 associated with the Devon EF Assets were determined using NYMEX pricing, without giving effect to derivatives transactions and were calculated based on settlement prices to better reflect the market expectations as of that date, as adjusted for estimates of quality, transportation fees and market differentials. The NYMEX reserves calculations are based on NYMEX futures pricing at closing on September 30, 2026 for oil and natural gas. The average adjusted product prices over the remaining lives of the properties are $70.60 per barrel of oil, $3.30 per Mcf of natural gas and $25.88 per barrel of NGLs as of September 30, 2026 for the Devon EF Assets. We believe that the use of forward prices provides investors with additional useful information about reserves estimates, as the forward prices are based on the market’s forward-looking expectations of oil and natural gas prices as of a certain date, although we caution investors that this information should be viewed as a helpful alternative, not as a substitute, for the data presented based on SEC pricing.

As of December 31, 2025 and including the net drilling locations gained through the Devon EF Assets Acquisition, we have identified 358.5 net locations as PUD drilling locations.

The Devon EF Assets consist of an aggregate of approximately 89 thousand net acres (97% operated), with average net production for the year ended December 31, 2025 and for the six months ended June 30, 2026 of approximately 56 MBoe/d (65% oil-weighted) and 71 MBoe/d (63% oil-weighted). As of December 31, 2025, the proved developed reserves associated with the Devon EF Assets reflect $1.4 billion and $1.7 billion in net present value (discounted at ten percent, or PD PV-10) at SEC pricing as of December 31, 2025 and NYMEX pricing as of September 30, 2026, respectively.

We estimate the current run-rate production associated with the Devon EF Assets, as measured for the month of July 2026, to be 68 MBoe/d. Additionally, we now expect that, giving effect to the Devon EF Assets Acquisition, our capital expenditures (excluding acquisitions) for the year ending December 31, 2026 will be approximately $1.75 billion (assuming that the Devon EF Assets Acquisition had closed on January 1, 2026 and using the midpoint of our 2026 capital expenditures estimate). We determine our capital expenditures depending on a variety of factors, including, but not limited to, the success of our drilling activities, prevailing and anticipated prices for oil and natural gas, the availability of necessary equipment, infrastructure and capital, the receipt and timing of required regulatory permits and approvals, seasonal conditions, drilling and acquisition costs and the level of participation by other working interest owners.

As of September 30, 2026, our derivative portfolio had an aggregate notional value of approximately $2.1 billion. We determine the fair value of our oil and natural gas commodity derivatives using valuation techniques that utilize market quotes and pricing analysis. Inputs include publicly available prices and forward price curves generated from a compilation of data gathered from third parties.

The following table details our net volume positions by commodity as of September 30, 2026.

(1)Represents outstanding crude oil swap options exercisable by the counterparty until December 2026 and June 2027.

(2)Represents outstanding crude oil three-way collar options exercisable by the counterparty until June 2027.

(3)Represents outstanding natural gas swap options exercisable by the counterparty until December 2026.

Summary reserve data based on NYMEX pricing

The following table provides our and the Devon EF Assets’ historical reserves, PV-0 and PV-10 as of December 31, 2025 using NYMEX pricing, individually and on a combined basis. We have included this reserve sensitivity in order to provide an additional method of presentation of the fair value of the assets and the cash flows that are expected to be generated from those assets based on the market’s forward-looking pricing expectations as of September 30, 2026. The historical 12-month average prices in our 2025 disclosures under the heading “—Summary reserve data based on SEC pricing” do not reflect the oil and natural gas futures. We believe that the use of forward prices provides investors with additional useful information about our reserves, as the forward prices are based on the market’s forward-looking expectations of oil and natural gas prices as of a certain date, although we caution investors that this information should be viewed as a helpful alternative, not a substitute, for the data presented based on SEC pricing. In addition, we believe strip pricing provides relevant and useful information because it is widely used by investors in our industry as a basis for comparing the relative size and value of proved reserves to our peers and in particular addresses the impact of differentials compared with our peers. Our and the

Devon EF Assets’ estimated historical reserves, PV-0 and PV-10 based on NYMEX pricing, were otherwise prepared on the same basis as our and the Devon EF Assets’ respective estimations based on SEC pricing reserves for the comparable period. Reserve estimates using NYMEX pricing are calculated using the internal systems of our management and have not been prepared or audited by an independent, third-party reserve engineer, but otherwise contain the same parameters, except for price and minor system differences.

(1)Our NYMEX reserves, PV-0 and PV-10 were determined using NYMEX pricing, without giving effect to derivative transactions and were calculated based on settlement prices to better reflect the market expectations as of that date, as adjusted for our estimates of quality, transportation fees, and market differentials. The NYMEX reserves calculations are based on NYMEX pricing at closing on September 30, 2026 for oil and natural gas. The average adjusted product prices over the remaining lives of the properties are $69.05 per barrel of oil, $2.37 per Mcf of natural gas and $20.42 per barrel of NGLs as of September 30, 2026 for Crescent Energy Company. We believe that the use of forward prices provides investors with additional useful information about our reserves, as the forward prices are based on the market’s forward-looking expectations of oil and natural gas prices as of a certain date, although we caution investors that this information should be viewed as a helpful alternative, not as a substitute, for the data presented based on SEC pricing.

(2)Present value (discounted at PV-0 and PV-10) is not a financial measure calculated in accordance with GAAP because it does not include the effects of income taxes on future net revenues. Neither PV-0 nor PV-10 represent an estimate of the fair market value of our oil and natural gas properties. Our PV-0 measurement does not provide a discount rate to estimated future cash flows. PV-0 therefore does not reflect the risk associated with future cash flow projections like PV-10 does. PV-0 should therefore only be evaluated in connection with an evaluation of our PV-10 of discounted future net cash flows. We believe that the presentation of PV-0 and PV-10 is relevant and useful to our investors about the future net cash flows of our reserves in the absence of a comparable measure such as standardized measure. We and others in our industry use PV-0 and PV-10 as a measure to compare the relative size and value of proved reserves held by companies without regard to the specific tax characteristics of such entities. Investors should be cautioned that neither of PV-0 and PV-10 represent an estimate of the fair market value of our proved reserves. GAAP does not prescribe any corresponding measure for PV-10 of reserves based on pricing other than SEC pricing. As a result, it is not practicable for us to reconcile our PV-10 using NYMEX pricing to standardized measure as determined in accordance with GAAP.

(3)The reserves, PV-0 and PV-10 associated with the Devon EF Assets were determined using NYMEX pricing, without giving effect to derivative transactions and were calculated based on settlement prices to better reflect the market expectations as of that date. The NYMEX reserves calculations are based on NYMEX pricing at closing on September 30, 2026 for oil and natural gas. The average adjusted product prices over the remaining lives of the properties are $70.60 per barrel of oil, $3.30 per Mcf of natural gas and $25.88 per barrel of NGLs as of September 30, 2026 for the Devon EF Assets. We believe that the use of forward prices provides investors with additional useful information about reserves estimates, as the forward prices are based on the market’s forward-looking expectations of oil and natural gas prices as of a certain date, although we caution investors that this information should be viewed as a helpful alternative, not as a substitute, for the data presented based on SEC pricing.

(4)Pro forma reserve data generally represents the arithmetic sum of the proved reserves, the standardized measure, PV-0 and PV-10 attributable to Crescent Energy Company and the Devon EF Assets. The proved reserves of the Devon EF Assets are based on its development plan and its reserve engineer’s reserve estimation methodologies. Because we will develop such proved reserves in accordance with our own development plan and, in the future, will estimate proved reserves in accordance with our own methodologies, the estimates presented herein for the Devon EF Assets may not be representative of our future reserve estimates with respect to these properties or the reserve estimates we would have reported if we had owned such properties as of December 31, 2025.
