For new construction requested by Antero Resources, Antero Midstream can elect either minimum volume commitments or a cost-of-service fee structure3738 - The growth incentive fee program, which provided fee rebates for achieving volume targets, expired on December 31, 2023. Antero Resources earned $52 million in rebates in 202339 - The water services agreement runs through 2035 and includes a fixed fee for fresh water delivery and a cost-of-service or cost-plus-3% fee for other fluid handling services40 Regulation of Operations The company's operations are subject to extensive regulation at federal, state, and local levels, including pipeline safety regulations from PHMSA mandating integrity management programs with increased penalties, and environmental regulations under the Clean Air Act, Clean Water Act, and RCRA governing air emissions, water discharges, and waste management, with significant regulatory focus on hydraulic fracturing, methane emissions, and climate change, imposing more stringent requirements and potential costs through new EPA rules and the Inflation Reduction Act of 2022, which the company actively manages through compliance programs and ESG initiatives - Natural gas gathering facilities are generally exempt from FERC jurisdiction under the Natural Gas Act, but this classification is determined on a case-by-case basis and could change48 - Gas pipelines are subject to safety regulations by PHMSA, which require integrity management programs. Maximum civil penalties for violations were increased in January 2024 to $266,015 per violation per day5456 - In December 2023, the EPA finalized stringent new rules (Subparts OOOOb and OOOOc) to reduce methane emissions from new, modified, and existing oil and gas facilities, which will increase compliance costs77 - The Inflation Reduction Act of 2022 imposes a federal fee on excess methane emissions from certain oil and gas facilities, starting in 2024 at $900 per ton and rising to $1,500 by 202679180 - The company is pursuing ESG goals, including a 2022 methane leak loss rate of 0.031%, well below the OneFuture industry target of 1%. It has implemented various projects to reduce emissions, such as blowdown capture systems and continuous monitoring technology8081 - The SEC and the state of California are advancing rules that will require extensive climate-related disclosures, including Scope 1, 2, and 3 GHG emissions, which could increase compliance costs and litigation risks86187 Human Capital Antero Midstream's workforce consists of 604 personnel concurrently employed by both the company and Antero Resources under secondment and services agreements, with a focus on attracting and retaining talent through competitive compensation, comprehensive benefits including health insurance, 401(k), and paid parental leave, professional development support, and a strong emphasis on workforce health and safety, while fostering a diverse and inclusive workplace culture - As of December 31, 2023, 604 people were concurrently employed by Antero Midstream and Antero Resources under services and secondment agreements91 - The company offers a comprehensive benefits package, including health insurance with no employee premium increases in over 16 years, a 401(k) plan, paid parental leave, and student loan repayment matching92 - A core value is safety, with a goal of zero incidents. The company promotes a strong safety culture through training, risk assessments, and empowering employees to stop unsafe work9596 Risk Factors The company faces significant risks, primarily stemming from its heavy reliance on Antero Resources, its sole major customer, where any adverse developments affecting Antero Resources' operations, financial health, or development plans directly impact Antero Midstream's revenue and growth, alongside operational risks including potential production shut-ins, construction delays, and cost overruns, exposure to capital structure risks such as debt service obligations and access to capital, substantial regulatory risks with increasing scrutiny on environmental compliance, pipeline safety, and climate change potentially leading to higher costs and operational constraints, and other notable risks including geographic concentration in the Appalachian Basin, potential conflicts of interest with related parties, and tax-related uncertainties Customer Concentration Risks The company's financial performance is overwhelmingly dependent on Antero Resources, which accounts for substantially all of its revenue, exposing Antero Midstream to Antero Resources' business risks including commodity price volatility, changes in drilling plans, and financial distress, where a decline in Antero's production or well completion activity, or a disposition of dedicated acreage, would directly and adversely affect Antero Midstream's business and operating results - Substantially all revenue is derived from Antero Resources, making the company highly vulnerable to any adverse events affecting Antero's production, financial condition, or market reputation101 - The company's success depends on Antero Resources' ability to replace naturally declining production from existing wells. A reduction in Antero's development activity would directly harm gathering, compression, and water handling revenues105106 - Under certain conditions, Antero Resources can dispose of dedicated acreage free from dedication without Antero Midstream's consent, which could reduce future volumes and revenue111 Business Operations Risks Operational risks include the potential for material production shut-ins by customers due to market imbalances or storage constraints, which would reduce throughput, with the company's gathering and compression agreements containing minimum volume commitments only under specific circumstances for new assets, and construction of new assets being subject to risks of delays and cost overruns, while the business is also exposed to rising costs for materials like steel due to trade tariffs, potential disruptions from third-party pipeline unavailability, and increasing attention to ESG matters which could raise costs and reduce demand - A material shut-in of production by customers like Antero Resources, potentially due to storage capacity constraints or low demand, would reduce volumes and adversely affect business112113 - Minimum volume commitments are limited to new high-pressure pipelines and compressor stations built at Antero's request; there are no such commitments on low-pressure or fresh water pipelines114 - Increasing attention to ESG matters may result in increased costs, reduced demand for oil and gas products, and negative impacts on stock price and access to capital. The company faces risks related to meeting its own aspirational ESG targets, such as its net-zero goal by 2050126128 - The business involves significant operational hazards (fires, ruptures, spills) that may not be fully covered by insurance, potentially leading to substantial uninsured losses130131 Capital Structure and Financial Risks The company faces risks related to its ability to generate sufficient cash to service its debt, including a revolving credit facility and senior notes, where failure to do so could force asset sales or refinancing on unfavorable terms, and future growth requires significant capital expenditures, with the ability to obtain financing depending on market conditions and the company's financial health, while existing debt agreements contain restrictive covenants that could limit operational flexibility, and rising interest rates could adversely affect business results - The ability to service debt obligations depends on operating performance and financial conditions that are subject to factors beyond the company's control. Insufficient cash flow could force asset sales or unfavorable refinancing136137 - Expansion requires capital expenditures, and the ability to obtain financing on satisfactory terms is not guaranteed. Incurring more debt would increase leverage, while issuing equity could dilute existing stockholders138139 - The revolving credit facility and senior note indentures contain restrictive covenants that limit the ability to incur more debt, make certain investments, merge, or dispose of assets141142 - A 1.0% increase in interest rates would have increased 2023 interest expense by an estimated $8 million, based on average outstanding borrowings under the revolving credit facility146 Regulatory and Compliance Risks The company operates under complex and stringent federal, state, and local regulations that could increase costs or cause delays, with key risks including the potential for gathering assets to become subject to FERC regulation, increased regulation of hydraulic fracturing, and significant costs to comply with environmental laws like the Clean Air and Clean Water Acts, while climate change presents a major risk, with new regulations like the IRA's methane fee and more stringent EPA rules potentially increasing operating costs, and pressure from investors and financial institutions potentially restricting access to capital - Operations are subject to complex laws requiring numerous permits. Failure to comply or changes in regulations could lead to substantial costs, operational delays, and penalties163164 - There is a risk that gathering facilities could be reclassified as transmission, subjecting them to FERC regulation, which could decrease revenue and increase operating costs168169 - Increased regulation of hydraulic fracturing could lead to delays and higher costs for customers, reducing throughput on Antero Midstream's systems172175 - The Inflation Reduction Act of 2022 imposes a new methane emissions fee and provides incentives for renewable energy, which could increase operating costs and accelerate the transition away from natural gas179180 - Climate change risks include increased operating costs from new GHG regulations, litigation risk, and reduced access to capital as financial institutions shift away from fossil fuels181186 Cybersecurity Antero Midstream has established a comprehensive cybersecurity risk management program integrated into its overall enterprise risk management, which includes continuous risk assessments, monitoring by an internal security team and third-party consultants, an incident response plan, and regular employee training, with the Audit Committee of the Board of Directors providing oversight and receiving regular updates from the Chief Administrative Officer, who leads the cybersecurity strategy, and while the company has not experienced any material incidents to date, it acknowledges the evolving nature of cyber threats - The company employs a cybersecurity risk management process that includes continuous automated and manual risk assessments, monitoring of threat intelligence, and annual penetration testing by a third-party consultant224 - The Board of Directors' Audit Committee oversees cybersecurity risks, receiving quarterly updates from the Chief Administrative Officer (CAO) who is responsible for managing the company's cybersecurity strategy and response231 - As of the report date, the company is not aware of any cybersecurity threats or incidents that have materially affected or are reasonably likely to materially affect its business233 Legal Proceedings The company is involved in various legal proceedings arising in the ordinary course of business, maintaining insurance policies it believes are reasonable and prudent but cannot guarantee they will be adequate for all potential claims, with detailed information on contingencies referred to Note 15 of the consolidated financial statements - The company is subject to various legal proceedings in the ordinary course of business and maintains insurance coverage it deems reasonable234 Part II Market for Common Equity, Stockholder Matters, and Issuer Purchases Antero Midstream's common stock trades on the NYSE under the symbol "AM", with Antero Resources holding a 29.0% interest as of February 9, 2024, and the company declared a quarterly dividend of $0.2250 per share in January 2024, while in February 2024, the Board authorized a new share repurchase program for up to $500 million of its common stock, and during the fourth quarter of 2023, share purchases were limited to shares withheld to satisfy tax obligations on employee equity awards - The company's common stock is listed on the NYSE under the symbol "AM".

As of December 31, 2023, the company had $630 million of borrowings outstanding under its $1.25 billion Credit Facility, leaving $620 million of available capacity287419 Critical Accounting Estimates The company's critical accounting estimates involve significant judgment and assumptions, with key areas including Property and Equipment, where estimates of useful lives, salvage values, and impairment assessments based on future cash flow projections are crucial, and Income Taxes, which requires assessing the realizability of deferred tax assets, particularly net operating loss carryforwards, and determining the need for a valuation allowance based on projections of future taxable income - Estimating depreciation for Property and Equipment requires judgment on useful lives and salvage values. Impairment is assessed using undiscounted future cash flow projections when triggering events occur294295 - Accounting for income taxes is critical, involving the assessment of deferred tax assets and liabilities. A valuation allowance is recorded if it is more-likely-than-not that some portion of deferred tax assets will not be realized, which depends on generating future taxable income296297 Quantitative and Qualitative Disclosures About Market Risk The company's primary market risks are interest rate risk, credit risk, and indirect commodity price risk, with direct commodity price exposure being minimal due to fixed-fee contracts, but it is indirectly exposed through the impact of commodity prices on its main customer, Antero Resources, and interest rate risk stemming from floating-rate borrowings under its Credit Facility, while credit risk is highly concentrated with Antero Resources, making the company vulnerable to any non-payment or adverse financial developments affecting them - Direct commodity price risk is limited due to fixed-fee and cost-of-service contracts, but the company is indirectly exposed to commodity price volatility through its impact on Antero Resources' development plans300 - The company is exposed to interest rate risk from its floating-rate Credit Facility. A 1.0% increase in the interest rate would have resulted in an estimated $8 million increase in interest expense for 2023301 - Significant credit risk exists due to the dependency on Antero Resources as the primary customer. Any non-payment or non-performance by Antero could adversely affect revenues and operating results302303 Controls and Procedures Based on an evaluation conducted by management, including the principal executive and financial officers, the company concluded that its disclosure controls and procedures were effective at a reasonable assurance level as of December 31, 2023, with no material changes to the internal control over financial reporting during the fourth quarter of 2023, and management's report also affirmed the effectiveness of the company's internal control over financial reporting, which was audited by KPMG LLP - Management, including the CEO and CFO, concluded that disclosure controls and procedures were effective as of December 31, 2023305 - Management concluded that the company's internal control over financial reporting was effective as of December 31, 2023, based on the COSO 2013 framework.
