Executive Summary 5

Executive Summary • Adeptus Health Inc. (NYSE: ADPT) provides emergency medical care through the largest network of independent freestanding emergency rooms (“FSERs”) in the United States and has joint ventures and partner services agreements with leading healthcare systems • As of November 1, 2016, Adeptus had 105 facilities in 4 states, including 101 FSERs and 4 hospitals • Although the Company has shown impressive growth since IPO in 2014, Adeptus has recently faced pressure on its liquidity, which has led to a net cash usage of ~$99mm over the last four quarters(1). The liquidity challenges have been driven by several factors: • • • Revenue Cycle Management Working Capital Support for JV Entities Q3 Utilization and Patient Volumes • Although the overlay of these issues has resulted in weak free cash flow generation in the Company’s most recent quarter, Adeptus is well-positioned for future growth and a return to operating normalcy over the next year • The Company has engaged Goldman Sachs to explore various financing alternatives to assist in the effort to achieve, subject to market conditions, a comprehensive refinancing that provides Adeptus with additional financial flexibility • Pro Forma for the recently announced preferred equity issuance and credit facility upsize, the Company’s Total Leverage will be 2.4x and its Rent Adjusted Leverage will be 3.2x, with $64 million of available liquidity(2) Please see page 30 for additional detail. Please see page 41 for additional detail. (1) (2) 6

Operational Challenges and Adeptus’ Response 1 ~$103mm Use of Cash in LTM 9/30/2016 2 3 7 Q3 Underperformance • Softer Q3 performance was not unique to Adeptus • Non-HOPD markets drove most of the Q3 year-over-year declines, but by year end more than 80% of Adeptus’ facilities are expected to be HOPD • Positive October volume data, particularly in newly HOPD markets JV Working Capital ~$54mm Use of Cash in LTM 9/30/2016 • Adeptus is working with JV partners to share the burden of increased working capital • Q3 represented a peak for pre-opening expenses • The new partner services model going forward is less capital-intensive Revenue Cycle Management • Combination of growth in the business as well as receivables management has caused systemwide DSOs to increase from 54 days in Q3 2015 to 102 days in Q3 2016 • Third-party specialists engaged to address underpayment • Adeptus has a history of collecting nearly all of its net revenue

Common Questions Question Response What is the cost of a FSER compared to an acute care hospital ER? Are you treating patients who should instead be seen at an urgent care facility? Are you in-network or out-of-network? 17 • In JVs and the partner services model, FSERs that have HOPD status operate under the same in-network agreements as their hub hospital • In non-partnered facilities, FSER billing is processed directly or through a secondary network relationship (e.g. MultiPlan) • The American College of Emergency Physicians establishes a scale of acuity, where cases rated 3-5 should be seen in an emergency setting — ~93% of our patients have an acuity level of 3 or greater • The cost of a FSER is generally equivalent to an acute care hospital ER given the level of care is comparable • In a joint venture, the FSERs bill under the parent hospital’s provider number

Revenue Cycle Management 1 Revenue Cycle Issues In October 2015, McKesson took over the Company’s billing and collections processes — Pre-McKesson, the Company had an internal billing and collections team that actively followed up with payors to ensure appropriate and timely reimbursement — The decision to outsource was driven by the need to ensure compliance with regulatory ICD-10 medical coding requirements Since McKesson assumed billing and collections roles, systemwide DSOs have spiked from 54 days in Q3 2015 to 102 days in Q3 2016(1) Peer DSO Comparables Solutions Adeptus has engaged third-party specialists to actively review claims data and resolve claims on a micro level • • — Billing and collections process for FSERs is high-touch, but McKesson’s methods are automated and low-touch One of these specialists has worked with the Company in the past on the manual process of collecting bad debt expense from individual patients and is familiar with Adeptus and its business model — • • The third-party specialists improve Adeptus’ ability to receive the appropriate level of reimbursement from commercial payors — Third-party specialists are compensated based on amount of receivables recovered in commercial claim appeals Specialists are already working with payors and initial feedback is positive 110 102 100 90 — 80 70 • The growth of Adeptus’ joint venture and partner services models should reduce billing disputes 60 52 49 43 50 — In the JV and partner services models, Adeptus’ FSERs bill under the parent hospital’s provider number 40 30 Mar-14 Sep-14 Adeptus (1) Mar-15 Sep-15 Mar-16 Sep-16 Ambulatory Surgery Center A Hospital A Ambulatory Surgery Center B (1) Calculated based off of systemwide revenues and systemwide receivables. 31 DSO (days) 65

Adeptus’ Current JV Model 2 • Adeptus earns both a management fee and physician staffing fee, as well as a share of the profitability of the JV — In the Dallas and Colorado JVs, Adeptus receives all of the initial JV profitability (the “Preferential Earnings”), until a threshold is reached and any excess earnings or losses are shared with the JV partner based on the ownership stake To date, Adeptus has funded the historical working capital needs of the JV, which has impacted near-term liquidity as those JVs have ramped — Adeptus is positioned first in the waterfall of payments until it is reimbursed for the working capital it has funded • Adeptus Health LLC. Adeptus Legacy Non-JV Operations (100%) Adeptus Health Management Entity (100%) Adeptus JV Participant (~50%) JV Partner (~50%) Earnings JV Entity (1) NMP revenues and / or staffing management fees are National Medical Professionals management and staffing fees, which are payable to Adeptus. NMP Arrangements are in accordance with applicable state corporate practice of medicine guidelines.

Addressing the JV Working Capital Need 2 JV Benefits Increased traffic, from both commercial and government pay patients (which can be profitable given low marginal cost) —The branding and network associated with partnered health systems enhances Adeptus’ visibility to commercial patients, while the hospital affiliation also enables the Company to accept government reimbursement Expansion of addressable markets, allowing Adeptus to pursue growth in new states (e.g. Ochsner Health System in Louisiana, Mount Carmel Health System in Ohio) Receipt of a management and physician staffing fee and a preferred distribution on the JV stake (in DFW and Colorado), in addition to JV profitability Ability to operate under the JV partners’ managed care contracts and bill at the already contracted rate JV Challenges Adeptus to date has funded 100% of net working capital needs at the JV level, though the Company has limited contractual obligations to do so Working capital usage at the JV entities has been compounded by revenue cycle management issues Solutions Adeptus is exploring a comprehensive refinancing plan that would provide the Company with additional financial flexibility • • • The Company expects to work with JV partners to share the upfront working capital burden — Adeptus has limited contractual obligations to fund JV working capital needs • • The Company’s JV model continues to evolve toward a new, capital-light partner services model • — With the Ochsner Health System (Louisiana) model, through the partner services agreement, Adeptus does not need to incur the capital outlay of building and supporting a new hospital and does not fund the JV’s working capital ramp for new HOPDs • • Adeptus’ engaged third-party specialists are already working with payors, and initial feedback is positive • • 34

JV Partnerships’ Impact on Other Receivables 2 • To date, Adeptus has funded 100% of net working capital needs at the JV level, although with limited contractual obligations to do so —An Adeptus-funded cash deficit at the JV entity increases Adeptus’ “Other Receivables” balance Significant growth in Adeptus’ JVs, including growth in facilities, has caused the balance of Other Receivables to increase (notably, the opening of the Denver and Colorado Springs hospitals associated with the existing UC Health JV in 2H 2016) —Additionally, entrance into the Texas Health Resources JV (Q2 2016) has resulted in higher Other Receivables due to the requirement to rebuild working capital at the contributed facilities • Historical Balance of Other Receivables $120 10 8 6 $57.4 $38.6 $48.8 $31.5 4 2 0 Note: Count of number of JV Hospitals in Q3 2016 includes Colorado Springs hospital to open in Q4 2016.

Elevated Pre-Opening Expenses Associated with JV Growth Should Subside 2 Elevated Pre-Opening Expenses Adeptus opened three hospitals in 2H 2016, two of which are contributed to JVs One additional JV hospital is anticipated to come online in Q2 2017 Adeptus is responsible for the labor, marketing and occupancy costs ahead of opening new facilities Solutions Adeptus opened three hospitals in Q3 2016 to move toward a hospital-affiliated HOPD model in more of its markets — ~79% of FSERs are HOPD as of November 1, compared to ~40% at the beginning of Q3 — ~83% of all facilities are expected to be HOPD by year end Going forward, pre-opening expenses will decline, with only one additional hospital opening (Mesa, AZ) in 2017 New FSER facilities tend to have minimal preopening expenses (average of ~$250,000 per new build) and favorable economics, with a rapid ramp to profitability Adeptus is also actively evaluating cost-cutting opportunities and analyzing planned FSER openings • • • • — New hospitals are associated with significantly higher pre-opening expenses compared to new FSER facilities • • • 36 (in thousands) Q1 2016 Q2 2016 Q3 2016 Total Hospital Preopening Expenses ~$200 ~$1,300 ~$12,000 FSERs (21 opened in YTD 2016) ~1,700 ~2,000 ~2,000 Total Preopening Expenses $1,941 $3,294 $14,056

Q3 Financial Performance 3 Performance Q3 is generally the weakest quarter for providers Solutions The healthcare services industry is seeing a continuing shift of volumes from inpatient to outpatient settings • • — Patient volumes are sensitive to seasonal fluctuations in emergency activity — Adeptus is well-positioned to take advantage of this industry shift Adeptus improves access to care by efficiently bringing high-quality care to local communities — — Across the industry, hospitals and healthcare services providers have faced softer volumes and a number of tailwinds to Q3 performance • Since quarter end, Houston and Denver hospital openings have become HOPD markets. The Colorado Springs sites are expected to be converted to HOPDs by the end of the year Same-Store HOPD Patient Volume • Non-HOPD markets, which cannot accept government reimbursement, represented most of the Q3 decline Same-Store Non-HOPD Patient Volume San Antonio Austin Colorado Springs Denver Houston 2,191 3,124 3,175 5,331 16,142 1,358 2,201 4,259 4,641 11,784 -38.0% -29.5% 34.1% -12.9% -27.0% DFW Arizona Colorado Springs Denver Houston 16,085 6,953 25,052 7,034 55.7% 1.2% Expected to become HOPD in Q4 2016 Converted to HOPD Sept. 20, 2016 Converted to HOPD Oct. 11, 2016 Non-HOPD Total 29,963 24,243 -19.1% HOPD Total 23,038 32,086 39.3% Note: Same –Store Patient Volume analysis only includes facilities at least 16 months into opening.

October 2016 Performance Update 3 • • Preliminary October 2016 results already reflect volume uplift relative to Q3 2016 financial results Conversion to HOPD represents a key top-line growth driver, as demonstrated by October volumes, even in markets that only transitioned to HOPD in the past two months —Denver only became a HOPD market on September 20, while Houston converted to HOPD on October 11 With the anticipated conversion of the Colorado Springs market to HOPD by year-end (upon the receipt of certification), ~83% of Adeptus’ facilities are expected to be HOPD • FSER Patient Volumes 38 MarketOct. 2016Q3 2016 Oct. 2016 as a % of Q3 2016 HOPD Conversion Date DFW14,41537,008 39.0% Oct. 2015 Arizona9,22025,333 36.4% Oct. 2014 Houston7,35415,222 48.3% Oct. 2016 Denver4,63210,182 45.5% Sep. 2016 New Orleans793-NA Oct. 2016 Total – HOPD Markets36,41487,745 41.5% Colorado Springs1,4184,230 33.5% Q4 2016 Anticipated Austin9052,644 34.2% NA San Antonio8982,578 34.8% NA Total – Non HOPD Markets3,2219,452 34.1%

Operational Challenges and Adeptus’ Response 1 ~$103mm Use of Cash in LTM 9/30/2016 2 3 39 Q3 Underperformance • Softer Q3 performance was not unique to Adeptus • Non-HOPD markets drove most of the Q3 year-over-year declines, but by year end more than 80% of Adeptus’ facilities are expected to be HOPD • Positive October volume data, particularly in newly HOPD markets JV Working Capital ~$54mm Use of Cash in LTM 9/30/2016 • Adeptus is working with JV partners to share the burden of increased working capital • Q3 represented a peak for pre-opening expenses • The new partner services model going forward is less capital-intensive Revenue Cycle Management • Combination of growth in the business as well as receivables management has caused systemwide DSOs to increase from 54 days in Q3 2015 to 102 days in Q3 2016 • Third-party specialists engaged to address underpayment • Adeptus has a history of collecting nearly all of its net revenue
