Promotora y Operadora de Infraestructura, S.A.B. de C.V. announces Unaudited Results for the Close of the Third Quarter of 2026 Mexico City, October 22, 2026. Promotora y Operadora de Infraestructura, S.A.B. de C.V. (BMV: PINFRA), a company engaged in the promotion, development, construction, financing and operation of infrastructure projects in Mexico, announces today its unaudited results for the third quarter ended September 30, 2026. For the purposes of this document, and unless otherwise indicated, the variation in figures refers to changes in the third quarter of 2026 compared with the same period of 2025. PINFRA is one of the leading companies in Mexico engaged in the promotion, development, construction, financing and operation of infrastructure projects. As of the date of this report, the Company holds 23 concession titles (as the sale of the Altamira Port Terminal was completed on July 9, 2025) comprising 30 toll roads (26 of which are in full operation, 2 in partial construction stage, one in construction stage and one with a pending procedure), one bridge operation contract and one electronic toll collection operation contract for the FONADIN toll road network. In addition to its core business, the company has 6 plants that produce asphalt mixes, as well as a construction segment focused primarily on the management and supervision of the construction and maintenance projects of the toll roads under the company's concession titles. Comments from the Chief Executive Officer “In 3Q26, PINFRA continued advancing in the execution of its projects and maintained a solid financial position to sustain its investment plan. We continue executing with financial discipline and a long-term vision for Mexico.” - David Peñaloza Alanís, Chief Executive Officer of PINFRA. 1

Relevant Events  Beginning this quarter, the comparison of revenues against the same period of the prior year is no longer materially affected by the deconsolidation of IPM. The sale of IPM (Altamira Port Terminal) was completed on July 9, 2025, so 3Q25 includes only a few days of its results and the effect on comparability is minimal. However, the items that reflect the gain on the sale of IPM in 3Q25 (EBITDA, operating income, net income and cash flow generated from operations) are not comparable with those of this quarter.  Mexico's Ministry of Infrastructure, Communications and Transportation (SICT) formalized, effective June 5, 2026, the amendment to the concession title of Concesionaria de Autopistas de Michoacán (Nueva Italia–Lázaro Cárdenas section). This amendment consists of widening the road from 2 to 4 lanes over approximately 80 kilometers, for which an investment of Ps. 6,375 million is estimated. The funding of this investment is being carried out through a combined scheme that includes: (i) a toll rate increase for freight vehicles on the Uruapan–Nueva Italia–Lázaro Cárdenas section; (ii) an agreement with the SICT under which, while the investment and its corresponding return are being recovered, the concessionaire may allocate to this purpose the proceeds from the revenue-sharing arrangement established in the concession title, with the original scheme resuming once the investment and its return have been recovered; and (iii) the subscription of rights to FVIA's CBFEs, in which PINFRA participated mainly with capital.  We continue with the widening works on the Armería-Manzanillo toll road, which began on November 16, 2022. These works consist of widening the toll road from 4 to 6 lanes over 46 km, as well as building improvements on sections of the so-called Libramiento Manzanillo. The investment for all works to be carried out in this project will be approximately Ps. 4,000 million. The main works are expected to be completed in October 2026, with the construction of complementary works continuing.  Regarding the works on the Paquete Michoacán: o On June 22, 2023, the works on the Paquete Michoacán project began in the presence of the Secretary of Communications and Transportation of the SICT. The work consisted of widening from 2 to 4 lanes over 22 km of the Pátzcuaro – Uruapan section, in the Zirahuén - Zirimícuaro stretch. The investment in this section of the project represented Ps. 1,683 million. To date, the 22 km of the section have been completed and are in operation. o On November 17, 2023, the official start of construction was given on the Uruapan – Nueva Italia section. The works on this section represent an investment of Ps. 6,500 million. Completion of this work is expected for August 2027. 2

 PINFRA won the tender for the Macrolibramiento Sur Colima project, which will be carried out with an estimated investment of Ps. 5,298 million. The project spans 28.8 km in total, construction began in June 2025, and completion is estimated for March 2027.  In 4Q23, the second amendment to the Concession Title of the Viaducto Elevado de Puebla was signed, which consists of a lane expansion and the construction of complementary works. The total investment is Ps. 530 million for the expansion works and Ps. 45 million for the works under the overpass. The consortium is split 49% for PINFRA and 51% for Aleatica. Works on this project will begin in November of the current year, with an approximate duration of 1 year.  During 2Q24, PINFRA won the tender for the construction project to widen from two to three lanes per direction over 43.1 kilometers of the Colima-Armería toll road. The toll road is adjacent to the road known as “Armería – Manzanillo”. PINFRA will invest Ps. 5,700 million, with operations tentatively starting in December 2026. Construction progress is approximately 76%. ESG Progress  The Board of Directors held its quarterly meeting in 3Q26 and approved the company's Quarterly Financial Statements.  The Audit and Corporate Practices Committees met prior to the Board of Directors meeting and submitted their reports to it.  As part of the convictions and the commitment of PINFRA to Sustainability, we continue our efforts and clear progress in our ESG strategy, with the goal of meeting the constantly increasing requirements and best practices in the industry, all in view of the upcoming implementation of the ISSB (IFRS) framework for BMV issuers after the close of fiscal year 2026. The following is a summary of the consolidated results for the quarter: Summary (Millions of Pesos) 3Q26 3Q25 3Q26 VS 3Q25 Net Revenues 6,639.7 4,993.2 33% EBITDA 3,304.2 14,492.4 -77% EBITDA Margin 50% 290% Operating Income (Loss) 3,053.5 14,194.7 -78% Operating Margin 46% 284% Net Income (Loss) 3,001.3 9,606.2 -69% Net Margin 45% 192% Earnings (Loss) per Share 7.0 22.4 -69% Cash Flow Generated from Operations 2,476.5 17,046.0 -85% 3

The consolidated revenues of the company reached Ps. 6,639.7 million, representing a 33% increase compared with the same period of the prior year. This is attributed to the positive performance of our toll road assets and their toll rate increases, which are the core of our business, as well as a high volume of work in the construction sector and higher asphalt mix sales compared with the same quarter of 2025. The EBITDA for the quarter was Ps. 3,304.2 million. Compared with the same period of the prior year, it is lower by Ps. 11,188.2 million, or 77%, since in the prior year this item reflected the gain from the sale of IPM. Excluding the gain from the sale of IPM in 3Q25, consolidated EBITDA for that quarter would have been Ps. 2,212.3 million, so this quarter would be 49% higher. The operating income was Ps. 3,053.5 million, 78% lower than in 3Q25, which stems from the aforementioned gain on the sale of the port. Excluding the gain from the sale of IPM in 3Q25, operating income would have been Ps. 1,914.6 million, so 3Q26 would be higher by Ps. 1,138.9 million, or 59%. The net income was Ps. 3,001.3 million, lower than in 3Q25 by Ps. 6,604.9 million, or 69% lower, also due to the effect of the sale of the port. Excluding the gain from the sale of IPM in 3Q25, net income for that quarter would have been Ps. 1,070.6 million, so 3Q26 would be higher by Ps. 1,930.7 million, or 180%. This improvement is explained, among other things, by the favorable comprehensive financing result, as well as by the operating performance of the 3 business lines. The cash flow generated from operations for 3Q26 was Ps. 2,476.5 million versus Ps. 17,046.0 million in the same period of 2025. This also reflects the cash inflow from the sale of IPM to TIL. Revenue Summary by Segment 3Q26 3Q26 3Q25 3Q25 Segment Amount (millions) % of total revenues Amount (millions) % of total revenues 3Q26 VS 3Q25 Concessions 4,158.6 63% 3,690.0 74% 13% Concession Toll Roads: 4,158.6 63% 3,653.6 73% 14% Securitized Toll Roads 89.9 1% 84.6 2% 6% Fibra E Toll Roads 1,488.3 22% 1,372.1 27% 8% Securitized Toll Roads in Fibra E 1,442.3 22% 1,207.7 24% 19% Non-Securitized Toll Roads 1,138.1 17% 989.3 20% 15% Altamira Port Terminal 0.0 0% 36.3 1% -100% Construction 2,384.0 36% 1,263.0 25% 89% Plants 97.1 1% 40.3 1% 141% 4

Total 6,639.7 100% 4,993.2 100% 33% Note: PINFRA holds a (direct and indirect) interest of approximately 82% of the taxable result in the Fibra-structured toll roads. Note 2: This table includes the revenues of the operating companies within the Non-Securitized Toll Roads. Note 3: Armería Manzanillo was reclassified as a non-securitized toll road beginning in 2Q25, and Tenango - Ixtapan de la Sal beginning in 3Q25. Note 4: Rumbo Nuevo began operating on February 14, 2026. The concession toll roads, which represented 63% of the company's revenues during 3Q26, recorded 14% revenue growth, driven by organic and sustained traffic growth, the growth of the toll road asset portfolio, as well as the toll rate increase on our assets. In the construction sector, which represented 36% of the company's revenues during 3Q26, revenues amounted to Ps. 2,384.0 million. This represents an increase of Ps. 1,121.0 million, or 89%, compared with the same period of the prior year, driven by a higher volume of work executed; the increases in construction reflect future growth in concessions-sector revenues, due to PINFRA's business model, in which all the resources invested in construction go toward generating new concessions. IFRIC in 3Q26 recorded Ps. 125.8 million compared with Ps. 290.9 million in 3Q25, a decrease of Ps. 165.0 million. As for the plants, they recorded revenues of Ps. 97.1 million, a significant increase compared with Ps. 40.3 million in 3Q25, driven by higher production and sales of asphalt mix. As a result of the above, the company's consolidated revenues grew 33%, driven by the performance of the toll road segment, growth in construction and higher asphalt mix sales. EBITDA by Segment 3Q26 3Q26 3Q25 3Q25 Segment Amount (millions) % of total EBITDA Amount (millions) % of total EBITDA 3Q26 VS 3Q25 Concessions 3,108.5 94% 14,571.0 101% -79% Construction 163.1 5% -82.6 -1% N.M.

We note, as in every quarter, that the results of the construction segment are non-recurring and do not represent a significant contribution to the company's consolidated EBITDA, given the inherent nature of the business. Important progress on the works:  The widening works continue on the Armería–Manzanillo toll road, which contemplate expanding from 4 to 6 lanes over 46 km, as well as improvements to the Libramiento Manzanillo. The estimated investment is Ps. 4,000 million and completion of the main works is expected in October 2026.  In the Paquete Michoacán: o The Pátzcuaro–Uruapan section (Zirahuén–Zirimícuaro), 22 km, with an investment of Ps. 1,683 million, has been completed and is in operation. o The Uruapan–Nueva Italia section, with an investment of Ps. 6,500 million, is under construction, with estimated completion in August 2027.  The Macrolibramiento Sur Colima, 28.8 km, is under construction, with an estimated investment of Ps. 5,298 million and expected completion in March 2027.  The widening project of the Colima–Armería toll road, which contemplates expanding from two to three lanes per direction over 43.1 km, has an investment of Ps. 5,700 million, shows approximate progress of 76% and is expected to be completed in December 2026.

Explanatory Notes Information to be disclosed on management's objectives and its strategies for achieving those objectives PINFRA believes that its main advantage as an administrator and operator of concessions is its focused and effective business model, which is based on identifying infrastructure projects, investing strategically in them, and subsequently managing them efficiently, in order to generate consistent and predictable cash flows. We develop self-sufficient concessions that generate rates of return with cash flows that the company considers attractive. To achieve the above, the company considers it essential to have cash resources that allow it to take advantage of opportunities that, due to their time-sensitive nature, would not otherwise be feasible. Company Policies: Management's vision is to sustain this low-cost strategy and remain attentive to developments in the economic environment, which will allow it to take the necessary measures in response to future events. It is worth mentioning that the company's value creation policy, as has been mentioned in the past, seeks a clear return through the following strategies:  The debt issued by the company is project debt obtained through securitizations whose only source of payment is the future flows from toll collections.  The company has no corporate debt or cross-guarantees among the group's various subsidiaries.  All securitizations are reflected in the accounting records and there are no off-balance-sheet transactions.  The construction segment is basically internal or, for the most part, for concessions, and entails revenue, cost and profit. Changes in the exchange rate do not affect the company's cash flows because toll road revenues, as well as their debt, are denominated in UDIs. The foreign exchange effects reflected in the comprehensive financing result are accounting (virtual) effects and do not represent cash flow. Tax Consolidation: The company has not consolidated for tax purposes since fiscal year 1999; therefore, the figures presented in this report will not be affected in this regard by the tax reform. 13

Risks related to the Company's activities The returns generated by some of the Company's concessions could be lower than forecast at the time the respective investment was made. The concessions are subject to rescue or revocation by the authorities under certain circumstances. The traffic volume on the Company's concessions could be lower than projected. Approximately 13% of the Company's 2025 annual revenues come from the operation of a single concession title. The provisions applicable to the establishment and adjustment of maximum toll rates do not guarantee that the concessions will be profitable or generate the expected levels of return. The Company is exposed to risks related to the construction, operation and maintenance of its projects. The Company could be unable to obtain new concessions. The Company's performance could be adversely affected by decisions of governmental authorities regarding the granting of new concessions for infrastructure works The Company is subject to regulation by the government at the federal, state and municipal levels, and current laws and regulations and their amendments could significantly affect the Company's activities, financial condition and results of operations. The Company is subject to a large number of environmental and safety legal provisions that could become stricter in the future and, therefore, impose greater liabilities and give rise to the need to make additional investments in assets. The Company's participation in Brownfield Projects entails certain risks. The Federal Government and state and municipal governments could expand third-party concessions or grant new concessions that compete with those of the Company, or build free (non- toll) roads or alternative ports, which could have an adverse effect on the Company's activities, financial condition and results of operations. Increases in construction costs and delays in the construction process, including delays in obtaining the Release of Right of Way and environmental permits, could adversely affect the Company's ability to comply with the construction requirements and schedules provided for in some of its concessions and adversely affect the Company's activities, financial condition and results of operations. Default by any of the Company's subsidiaries on its payment obligations under securities instruments may affect the Company's condition. The Company could experience difficulties in raising additional capital, which could affect its ability to carry out its activities or achieve its growth objectives. 16
