Proposal 1 – Election of Directors

Proposal 1 – Election of Directors

Our bylaws currently fix the number of directors at ten. Our board is currently composed of ten directors. All ten of our directors are standing for election to serve until the 2019 annual meeting or until a successor has been duly elected and qualified. You may not vote for more than ten nominees, either in person or by proxy.

Unless you direct otherwise, the persons named in the accompanying proxy will vote your shares for the election of the nominees named below. Each nominee has consented to be named and to continue to serve if elected. If any of the nominees becomes unavailable for election for any reason, the proxies will be voted for the other nominees and for any substitutes.

All of our directors bring to our board significant executive leadership experience derived from their service as executives and—in some cases—chief executive officers of large corporations. They also bring extensive board experience and a diversity of views and perspectives derived from their individual experiences working globally in a broad range of industries and occupations. For example, many of our directors have held senior management roles on notable merger and acquisition transactions and have demonstrated the ability to lead an organization through the execution and completion of complex commercial transactions. Certain individual experiences, qualifications, and skills of our directors that contribute to our board’s effectiveness as a whole are described under “—Nominees for Director.” No family relationships exist among any of our directors or executive officers.

Director Nomination Process

We are a “controlled company” within the meaning of the New York Stock Exchange (NYSE) listing standards, as described below, because SoftBank Group Corp. (f/k/a Softbank Corp.) and certain of its wholly-owned subsidiaries (together, “SoftBank”) hold more than 50% of the voting power for the election of our directors. SoftBank owned nearly 85% of Sprint Corporation (“Sprint” or the “Company” or “we,” “our,” or “us”) as of June 8, 2018.

For so long as SoftBank remains our controlling stockholder, our governing documents confer upon SoftBank certain rights. For example, SoftBank is able to elect all of the directors on our board. However, until SoftBank owns less than 50% of our outstanding voting power, the board will be required to include at least three independent directors or such greater number as may be required by applicable law or applicable rules of the stock exchange on which our stock is traded.

We consider all directors nominated by SoftBank, except our President and Chief Executive Officer (CEO), to be “SoftBank Designees.” SoftBank Designees who are not independent are known as “SoftBank Affiliate Directors.” In accordance with our bylaws, our board currently consists of our President and CEO (Michel Combes), five independent SoftBank Designees (Patrick Doyle, Gordon Bethune, Julius Genachowski, Stephen Kappes, and Sara Martinez Tucker), and four SoftBank Affiliate Directors (Masayoshi Son, Ronald Fisher, Marcelo Claure and Adm. Michael Mullen). If at any time SoftBank owns less than 50% of our outstanding voting power for ninety consecutive days, the board shall include a number of “SoftBank Designees” that is proportional to SoftBank’s voting interest, rounded up to the nearest whole number.

The Nominating and Corporate Governance Committee, or Nominating Committee takes an active role in evaluating prospective candidates or current board members for nomination, including those candidates nominated by SoftBank. In assessing the needs of our board at any given time, the

  Notice of Annual Meeting and Proxy Statement  |  3

Proposal 1 – Election of Directors

Nominating Committee considers all factors it deems relevant, including, but not limited to, the candidate’s:

_• character, including reputation for personal integrity and adherence to high ethical standards;

_• judgment;

_• knowledge and experience in leading a successful company, business unit, or other institution;

_• independence from our Company;

_• ability to contribute diverse views and perspectives;

_• business acumen; and

_• ability and willingness to devote the time and attention necessary to be an effective director.

Consistent with its charter and our Corporate Governance Guidelines, our Nominating Committee places a great deal of importance on identifying candidates who have a variety of views and perspectives arising out of their individual experiences, professional expertise, educational background, and skills. While we do not have a formal diversity policy, our board and our Nominating Committee believe that considerations of diversity are, and will continue to be, an important component relating to our board’s composition, as multiple and varied points of view contribute to a more effective decision-making process. In this regard, our board understands the importance of diversity to many of our stockholders, and has noted the empirical evidence published highlighting the correlation between enhanced board diversity and improved performance. Accordingly, our Nominating Committee also considers diversity of race, ethnicity, gender, age, and cultural background in evaluating director candidates for board membership. In considering candidates for our board, the Nominating Committee considers the totality of each candidate’s credentials in the context of the standards discussed above.

The Nominating Committee considers candidates recommended by our stockholders, using the same key factors described above for purposes of its evaluation. A stockholder who wishes to recommend a prospective nominee for our board should notify the Corporate Secretary in writing with supporting material that the stockholder considers appropriate. The Nominating Committee considers whether to nominate any person nominated by a stockholder pursuant to the provisions of our bylaws relating to stockholder nominations for election at an annual stockholder meeting. To nominate a director, the stockholder must deliver the information as required by our bylaws.

Board Operations

Board Operations

Because we are a controlled company, SoftBank has certain governance rights, which are detailed in our Certificate of Incorporation, bylaws, and other corporate governance documents available atwww.sprint.com/governance.

Corporate Governance Matters

We have elected to be treated as a “controlled company” under NYSE listing standards because SoftBank holds more than 50% of our voting power. Accordingly, we are exempt from certain requirements of the NYSE corporate governance rules, including the requirement that we have a majority of independent directors on our board and the requirement that the compensation and nominating and corporate governance committees of the board have written charters addressing certain specified matters. In addition, NYSE rules allow for a controlled company to havenon-independent directors on the compensation committee and nominating and corporate governance committee.

Governance Highlights

In keeping with good corporate governance practices, we maintain a comprehensive set of corporate governance initiatives that include the following:

✓ an Audit Committee comprised solely of independent directors;

✓ a Nominating Committee chaired by an independent director and comprised of a majority of independent directors;

✓ a Compensation Committee chaired by an independent director and comprised of a majority of independent directors;

✓ bylaws that provide, for so long as we are a controlled company, at least one member of our Compensation Committee and Nominating Committee will be independent;

✓ maintaining written charters for each of our standing committees;

✓ giving independent directors the ability to propose agenda items, including for executive sessions;

✓ refining our policies and goals with respect to the determination of executive compensation programs, including increasing emphasis on performance-based equity compensation, as further described under “Executive Compensation—Compensation Discussion and Analysis”;

✓ permitting our stockholders to take certain actions by written consent;

✓ adopting stock ownership guidelines for every officer at the level of senior vice president or above and fornon-employee directors;

✓ maintaining a declassified board;

✓ requiringnon-employee directors to hold executive sessions without management present no less than twice per year, which may be at or in conjunction with regularly-scheduled board meetings;

✓ publishing ourCorporate Governance Guidelines and charters for all standing committees of our board, which describe important aspects of our governance policies and practices, on our website;

✓ maintaining limits on the number of other public company boards and audit committees on which our directors may serve;

✓ adopting a policy that prohibits our independent registered public accounting firm from providing professional services, including tax services, to any employee or board member or any of their immediate family members that would impair the independence of our independent registered public accounting firm; and

✓ conducting annual board and committee evaluations for Audit, Compensation, and Nominating Committees.

12  |  Notice of Annual Meeting and Proxy Statement  

Board Operations

In the event we cease to be a controlled company within the meaning of NYSE’s rules, we would be required to comply with certain governance requirements after the transition periods specified by the NYSE.

Contacting our Board

We value the views of our stakeholders. Consistent with this approach, our board has established a system to receive, track, and respond to communications from stakeholders addressed to our board or to ournon-employee directors. A statement regarding our board communications policy is available atwww.sprint.com/governance.

Any stakeholder who wishes to communicate with our board or any director may write to our Chief Legal Officer or our Corporate Secretary, who are our Board Communications Designees, at the following address:

Sprint Corporation

6200 Sprint Parkway

Overland Park, KS 66251

KSOPHF0302-3B679

or email:boardinquiries@sprint.com.

Our board has instructed the Board Communications Designees to examine incoming communications and forward to our board, or individual directors as appropriate, communications deemed relevant to our board’s roles and responsibilities. Our board has requested that certain types of inappropriate communications not be forwarded, and be redirected if appropriate, such as: spam, business solicitations or advertisements, resumes or employment inquiries, service complaints or inquiries, surveys, or any threatening or hostile materials. At least one of the Board Communications Designees will review all appropriate communications and report on the communications to the chair of the Nominating Committee or the full Nominating Committee, the full board, or thenon-employee directors, as appropriate. The Board Communications Designees will take additional action or respond to letters in accordance with instructions from the relevant board source. Communications relating to accounting, internal accounting controls, or auditing matters will be referred promptly to members of the Audit Committee in accordance with our policy on communications with our board.

Board Leadership Structure

On May 31, 2018, Mr. Claure was appointed to the newly-created role of Executive Chairman, after serving almost four years as Chief Executive Officer, and Mr. Combes, our President, was appointed Chief Executive Officer. In light of our previously announced agreement to merge withT-Mobile, these changes were designed to allow Mr. Claure to focus his attention on securing regulatory approval of the contemplated transaction while allowing Mr. Combes to focus his attention on ourday-to-day operations and on executing our standalone plan.

Accordingly, our board has determined that it is in the best interest of the Company to designate Mr. Claure as Executive Chairman and for Mr. Fisher to continue to serve as thenon-executive Vice Chairman. Mr. Son, who previously served asnon-executive Chairman, will no longer serve in that capacity but will continue to serve as a director. Further, in addition to serving in his new role as Chief Executive Officer, Mr. Combes will continue to serve as President and as a director.

We believe our board leadership structure provides the appropriate balance of directors affiliated with SoftBank, independent directors, and Chief Executive Officer—all working together to represent the interests of our entire stockholder base.

  Notice of Annual Meeting and Proxy Statement  |  13

Board Operations

In part because of the unique qualifications and skills of our Executive Chairman and Vice Chairman, our board believes that this structure enhances its oversight of management. Further, it fosters the ability of our board to carry out its roles and responsibilities on behalf of the stockholders and benefits the Company’s overall corporate governance. Finally, our board believes that Mr. Claure’s service as Executive Chairman enhances management continuity and provides a valuable resource for Mr. Combes as he transitions to Chief Executive Officer.

Independence of Directors

Our board is currently comprised of ten members, five of whom are independent under NYSE rules (Messrs. Bethune, Doyle, Genachowski and Kappes and Ms. Tucker). Admiral Mullen was independent under NYSE rules throughout fiscal year 2017 but ceased to be independent effective as of June 1, 2018, the date he was appointed as Chairman of the SoftBank Advisory Board. As a matter of practice, our board undertakes an annual review of director independence. During this review, our board considers all transactions and relationships between each director or any member of his or her immediate family and the companies by which they are employed as an executive officer (if applicable) to determine whether they have any relationships with our Company and its affiliates. The purpose of this review is to determine whether any such relationships or transactions are considered “material relationships” that would be inconsistent with a determination that a director is independent. Our board has not adopted any “categorical standards” for assessing independence, preferring instead to consider and disclose existing relationships withnon-management directors and the Company. Our board observes all criteria for independence established by NYSE.

Executive Sessions

Sprint’snon-management directors regularly meet in executive sessions without any management participation by officers or employee directors. These executive sessions are held before, after or otherwise in conjunction with our board’s regularly scheduled meetings each year. Additional executive sessions are scheduled at the request ofnon-management directors.

Mr. Son presides over the executive sessions of our board. The committee chairperson chairs the executive sessions of his or her committee. If Mr. Son or the committee chairperson is not present, our Vice Chairman or another director is chosen to preside. Our board does not have a lead independent director. Our board may select a presiding director for any independent director executive sessions, as needed.

Risk Management

Our board takes an active role in overseeing management of the Company’s risks, both through its own consideration of risks associated with our operations and strategic initiatives and through its committees’ consideration of various risks applicable to that committee’s areas of focus.

The Audit Committee reviews enterprise risks as part of its purpose to assist our board in fulfilling the board’s oversight responsibilities with respect to the Company’s enterprise risk management program. The Audit Committee receives regular reports regarding enterprise risk management matters from members of management who oversee the Company’s Corporate Audit Services, or internal audit, and Legal Department and informs our board of such matters through regular committee reports. In addition to receiving regular reports from the Audit Committee concerning our enterprise risk management program, our board also reviews information concerning other risks through regular reports of its other committees, including information regarding financial risk management from the Finance Committee, compensation-related risk from the Compensation Committee, and governance-related risk from the Nominating Committee.

14  |  Notice of Annual Meeting and Proxy Statement  

Board Operations

Our management is responsible for ourday-to-day risk management. Our management, internal audit, and internal control areas serve as the primary monitoring and testing functions for company-wide policies and procedures, and manage theday-to-day oversight of the risk management strategy for our ongoing business. This oversight includes identifying and evaluating potential risks that may exist at the enterprise, strategic, financial, operational, IT and cybersecurity, compliance, and reporting levels.

We believe the division of risk management responsibilities described above is an effective approach for addressing the risks facing the Company and that our board leadership structure supports this approach.

Code of Ethics

Our code of ethics, the Sprint Code of Conduct, is available atwww.sprint.com/governance or by email atshareholder.relations@sprint.com. It describes the ethical and legal responsibilities of directors and employees of our Company and our subsidiaries, including senior financial officers and executive officers.

All of our directors and employees (including all senior financial officers and executive officers) are required to comply with the Sprint Code of Conduct. In support of the Code of Conduct, we provide employees with a number of avenues for reporting potential ethics violations or similar concerns or to seek guidance on ethics matters, including a 24/7 telephone helpline. The Audit Committee has established procedures for the receipt, retention, and treatment of complaints received by us regarding accounting, internal accounting controls, or auditing matters, including the confidential, anonymous submission by our employees of any concerns regarding questionable financial andnon-financial matters to the Ethics Helpline at1-800-788-7844, by mail to the Nominating and Corporate Governance Committee, c/o Sprint Corporation, 6200 Sprint Parkway, Overland Park, KS 66251, KSOPHF0302-3B679, or by email toethicshelpline@sprint.com. Our Chief Ethics Officer reports regularly on our ethics and compliance program to the Audit Committee and the Nominating Committee, as well as annually to the entire board.

Compensation Committee Interlocks and Insider Participation

During fiscal year 2017, our Compensation Committee consisted of Mr. Bethune and Adm. Mullen. Our Compensation Committee currently consists of Messrs. Bethune and Kappes and Adm. Mullen. None of the members of our Compensation Committee is or has been one of our employees or officers. None of our executive officers currently serves, or during the past fiscal year has served, as a member of the board of directors or compensation committee of another entity that has one or more executive officers serving on our Compensation Committee.

Board and Committee Meetings; Attendance

The Company does not have a policy requiring director attendance at its annual meeting. All of our directors who were serving at the time of last year’s annual meeting attended in person, except Mr. Son. Directors are expected to devote sufficient time to prepare properly for and attend meetings of our board, its committees, and executive sessions and to attend our annual meeting of stockholders. During fiscal year 2017, all directors attended at least 75% of the aggregate of the meetings of the board and of each of the board committees on which he or she served at the time, except Mr. Son, who attended 50% of such meetings. Mr. Son attended all of the meetings of the board, but was unable to attend several meetings of the Finance Committee due in part to scheduling issues complicated by time zone differences. When Mr. Son was unable to participate in these meetings, he provided our Vice Chairman, Mr. Fisher, with his thoughts in advance of the meetings, and was fully briefed by Mr. Fisher on discussions and decisions that were made during the meetings. Furthermore, Mr. Son has been a very actively engaged board and committee member, having frequent and regular discussions with our Executive Chairman, Vice Chairman, and CEO.

Components of Compensation

The following table summarizes director compensation for thenon-employee members of Sprint Corporation’s board, with the exception of Messrs. Fisher and Son, who are discussed further below.Ournon-employee directors are also reimbursed for direct expenses relating to their activities as members of our board.

(2) In addition to the compensation that directors receive for serving on our standing committees, our board retains the discretion to establish special committees from time to time and to pay a special retainer to the Chair and the members of any special committee, but excludes the Vacancy Resolution Committee.

(3) Generally, restricted stock units (RSUs) representing the right to receive shares of our common stock are granted each year on the date of the annual meeting of stockholders. Each grant generally vests in full on the earlier of the date of the subsequent annual stockholders’ meeting or the first anniversary of the date of the grant.

  Notice of Annual Meeting and Proxy Statement  |  21

Director Compensation

Mr. Son does not receive any fees for his service on our board. In recognition of his Vice Chairman activities and in lieu of the amounts described in the table above, including the annual board retainer, RSUs, and meeting fees, Mr. Fisher receives the following:

_• annual cash retainer of $500,000;

_• annual grant of $500,000 in RSUs at the annual stockholders’ meeting, which RSUs generally vest in full on the earlier of the date of the subsequent annual stockholders’ meeting or the first anniversary of the date of the grant; and

_• other benefits as described below.

Other Benefits

We believe that it serves the interests of our Company and our stockholders to provide our directors with communications services. Accordingly, eachnon-employee director is entitled to receive a reasonable amount of communication services and devices.Non-employee directors may also receive specialized equipment, on anas-needed basis, with equipment valued at greater than $1,000 requiring Compensation Committee approval. In addition to the value of the communications service, the value of any additional services and features and the value of the wireless devices, replacements and associated accessories are included in the value of the communications benefit. There may be other circumstances in which devices are provided to board members (such as demonstration, field testing and training units, or devices for use while traveling internationally); these devices must be returned or they will be converted to a consumer account and applied toward the wireless devices under this communications benefit.

We do not offer retirement benefits tonon-employee directors, except that our communications benefit as described above continues after retirement from board service for suchnon-employee directors for the period of time ournon-employee director served on our board (including service on our predecessor Sprint Nextel Corporation (Sprint Nextel) board).

Ournon-employee directors are provided the opportunity to elect before the end of each calendar year to defer the receipt of shares underlying any portion of any RSUs awarded in the following calendar year. Six of ournon-employee directors elected to defer the receipt of shares underlying their 2018 RSU awards vesting in 2019.

Stock Ownership Guidelines

Our board believesnon-employee directors should have a meaningful financial stake in the Company, and therefore has established a desired ownership level fornon-employee directors of equity or equity interests. Our director stock ownership guidelines currently requirenon-employee directors, other than SoftBank Affiliate Directors, to hold equity or equity interests equal to at least five times the annual board retainer amount (in other words, $537,500 while the current $107,500 retainer is in place). To the extent anynon-employee director has not met this minimum ownership level, each suchnon-employee director is expected to retain at least half of his or her shares or share equivalents awarded by us. Our board retains flexibility to grant exceptions to the guidelines based on its consideration of individual circumstances. As of March 31, 2018, each of ournon-employee directors met the stock ownership requirements, except for Mr. Doyle who joined our Board in December 2016 and is making progress towards achieving the stock ownership requirements.

Compensation Overview

Philosophy and Objectives of Our Executive Compensation Program

✓ Attract and retain qualified and experienced executives by providing base salaries, target incentives, and benefits that are market competitive;

✓ Hold executives accountable for their performance by requiring that a substantial portion of total compensation is earned over a multi-year period and subject to forfeiture to the extent that vesting requirements and performance objectives are not met;

✓ Pay for performance by tying a substantial portion of our executives’ compensation opportunities directly to, and rewarding them for, our performance through short- and long-term incentive compensation plans that include performance objectives most critical to driving our continued financial and operational improvement and long-term stockholder value; and

✓ Structure our compensation programs to align executive interests with those of our stockholders, mitigate the possibility that our executives undertake excessively risky business strategies, and adhere to corporate governance best practices.

Components of Our Executive Compensation Program

The major components of our executive compensation program for fiscal year 2017 were:

_• Base salary;

_• Short-term incentives under our short-term incentive compensation plan (STIC plan); and

_• Long-term incentives under our long-term incentive compensation plan (LTIC plan), as well as special performance-based equity awards that can be earned only based on performance of the price of Sprint stock (referred to as the “Turnaround Incentive Award” or “TIA award”).

Other components of our executive compensation program for fiscal year 2017 include the following benefits:

_• Change in control and severance benefits under employment agreements with our named executive officers and our Change in Control Severance Plan;

Executive Compensation

_• Retirement benefits under our 401(k) plan;

_• Perquisites and other benefits; and

_• Employee health and welfare benefits and programs.

Fiscal Year 2017 Performance

Fiscal year 2017 saw continued progress towards our transformation goals: we generated net income and returned to profitability for the first time in 11 years; our postpaid phone gross additions were the highest in six years; we achieved prepaid net additions for the first time in three years; and we enhanced our network performance to best-ever levels. Throughout the year, Mr. Claure and senior management continued to challenge each member of the Sprint team to work towards implementing and achieving the following transformation pillars:

Pillar	Strategy
Build Superior Network	Unlock the value of our substantial spectrum holdings by densifying and optimizing our network to provide customers with the best experience
Achieve Lowest Cost Structure	Achieve our cost reduction goals by significantly transforming our business
Lead in Customer Growth	Deliver an attractive value proposition and substantially enhance our distribution through use of innovative models
Achieve Sustained Profitability and Cash Generation	Create an alternative financial structure that leverages our assets to fuel our growth and maximize stockholder value
Create a High-Performance Work Environment that Employees Recommend	Attract and retain world-class talent and establish strategic partnerships to create the optimal, engaged, and winning team
Create Amazing Customer Experience that Customers Recommend	Deliver an exceptional wireless experience so customers stay longer, buy more, and tell their friends

We continued to demonstrate our commitment to repositioning Sprint in the wireless industry by executing on these imperatives in fiscal year 2017, including:

✓ Improving our network quality by completing thousands oftri-band upgrades on macro sites, adding thousands of outdoor small cells, and deploying more than 200,000 Sprint Magic Boxes, while also continuing to progress towards building the first mobile 5G network;

✓ Continuing to progress on our multi-year plan to improve our cost structure, as we delivered approximately $1.1 billion (excluding certainnon-recurring charges in fiscal year 2017) of combined year-over-year net reductions in cost of services and selling, general and administrative expenses, bringing the four-year total reduction to approximately $6 billion;

✓ Returning to profitability in fiscal year 2017, as we generated net income and delivered operating income of $2.7 billion, the highest operating income in company history;

✓ Improving our customer experience and offering an exceptional value proposition, which resulted in the third consecutive year of postpaid phone net additions and the highest postpaid phone gross additions in six years;

✓ Improving our financial flexibility by diversifying our funding sources that provide a lower cost of capital and retiring a portion of our debt maturities; and

✓ Recruiting leaders in our industry from around the globe and employing an organizational focus to ensure Sprint is a work environment employees recommend.

Executive Compensation

The compensation decisions in the last fiscal year were made to continue to help achieve these transformation pillars, as discussed below, and fiscal year 2017 was a year marked by significant progress towards our goals.

Key Fiscal Year 2017 Compensation Decisions

Base Salary

Base salary is designed primarily to attract and retain employees. Our named executive officers’ salaries are based on a number of factors, including the nature, responsibilities and reporting relationships of the positions that they hold, individual performance of the executive, salary levels for incumbents in comparable positions at peer companies as well as other executives within our organization, and experience and tenure of the executive. In fiscal year 2017, the Compensation Committee approved an increase to Mr. Gracia’s annual base salary from $625,000 to $725,000, effective November 11, 2017, based on market data. None of our other named executive officers received a salary increase in fiscal year 2017.

2017 STIC Plan

Our STIC plan is our annual cash incentive plan, which is intended to help ensure that annual incentives are tied to the successful achievement of critical operating and financial objectives that are the leading drivers of sustainable increases in stockholder value. Participants generally had to be employed on March 31, 2018 in order to earn STIC plan awards for the fiscal year 2017 performance period. A prorated payout was available for employees who were terminated during the year as the result of death, disability, retirement, or involuntary termination without cause. Under the STIC plan, our named executive officers are eligible to receive a target incentive opportunity, expressed as a percentage of base salary. Mr. Combes’s fiscal year 2017 target incentive opportunity was determined using market analytics, and the target opportunities (expressed as a percentage of base salary) for our other named executive officers did not change year-over-year. The target opportunities for the named executive officers for fiscal year 2017 are set forth in the table below.

Named Executive Officer	FY 2017 STIC Plan Target Opportunity (% of Base Salary)	FY 2017 STIC Plan Target Opportunity ($)
Claure	200	3,000,000
Combes	200	3,000,000(1)
Cano	100	1,300,000
Crull	100	800,000
Gracia	100	663,630(2)
Former Executive Officer
Robbiati	125	1,000,000(3)

(1) Mr. Combes’s actual fiscal year 2017 STIC plan target opportunity was $698,630, reflecting a proration of his target opportunity in light of his start date of January 6, 2018. Pursuant to the terms of his employment agreement, for fiscal year 2017, Mr. Combes was entitled to receive a payout equal to the greater of prorated target or actual performance.

Executive Compensation

(3) Mr. Robbiati’s actual fiscal year 2017 STIC plan target opportunity was $838,356, reflecting a proration of his target opportunity for the number of days he was employed during fiscal year 2017.

To further our goal of tying a significant portion of each named executive officer’s total annual compensation to our business performance, the STIC plan provided on anobjective-by-objective basis for a payment equal to the named executive officer’s targeted opportunity (set at a percentage of his base salary) only if our actual results met targeted performance levels. If our actual performance exceeded the targeted objectives, named executive officers were eligible for a payout in excess of their respective targeted opportunities (but capped at 200% of the target). Similarly, if our actual performance was below the target objectives, but exceeded the minimum threshold levels, named executive officers were eligible for a payout below their respective targeted opportunities. If the minimum aggregate threshold level of performance was not attained, no payments would be earned under the STIC plan. To ensure that the results under the formulaic STIC plan metrics fully reflected the Company’s overall performance for the year, the Compensation Committee retained discretion to adjust payouts atyear-end. As described in more detail in our discussion below under “Tax Deductibility of Compensation,” changes made by the 2017 Tax Cuts and Jobs Act generally eliminated the tax deduction exception for performance-based compensation under Section 162(m) of the Internal Revenue Code (IRC). We, however, intend to continue to grant performance awards.

The chart below summarizes the metrics and weightings set for theCorporate 2017 STIC plan in support of the transformational pillars previously discussed.

In determining the amount earned under the STIC plan, each named executive officer’s achievement was measured againstCorporate objectives. The Compensation Committee reviewed with management the degree to which each senior officer met certain specific individual performance objectives as well as qualitative assessments of each officer’s performance. The Compensation Committee elected not to make individual performance adjustments with respect to our named executive officers’ 2017 incentive awards, except that (1) the individual performance factor for each of Messrs. Claure and Gracia was increased to 125% in recognition of their substantial contributions to the Company in fiscal year 2017, including their leadership roles in overseeing the negotiation and execution of the Company’s definitive agreement to merge withT-Mobile and, in the case of Mr. Claure, his performance in leading the Company’s continued progress in implementing and achieving the transformation pillars discussed above, and (2) Mr. Robbiati’s individual performance factor defaulted to 75% as a result of his termination pursuant to the design of the 2017 STIC plan.

Executive Compensation

Actual results based on the objectives and targets set for theCorporate 2017 STIC plan are outlined in the table below and resulted in an initial payout level of 96.1% of target opportunity:

Objective	Fiscal Year 2017 Minimum Threshold		Fiscal Year 2017 Target		Fiscal Year 2017 Maximum		Actual Results		Earn-out Percentage
Service Revenue Less Operating Expense Less Handset Depreciation		$6,900,000,000		$7,047,000,000		$7,547,000,000		$7,277,000,000	146.09%

Improvement in Sprint Promoter Score(2)		1		7		11		(2)	0%
Corporate Payout Percentage									96.1%

(1) After the Compensation Committee established the original 2017 STIC plan award objectives and targets, a change was made to the Company’s budget—no longer were new subscribers that never made a payment under their contract counted as both gross additions and deactivations, but were simply not counted as gross additions. As a result, in October 2017, the Compensation Committee modified the original performance targets for the Postpaid Handset Gross Additions and Postpaid Handset Deactivations metrics, the only metrics affected by this change, to account for this change in approach.

(2) Based on customer surveys in which customers are asked how likely they are to recommend Sprint.

Accordingly, the named executive officers received STIC plan payments as follows:

Named Executive Officer	FY 2017 STIC Plan Target Opportunity ($)		Aggregate Payout Percentage (%)		FY 2017 STIC Plan Payout ($)
Claure(1)		3,000,000		96.1		3,603,750
Combes(2)		3,000,000		100.0		698,630

Robbiati(4)		1,000,000		96.1		604,245

(1) As previously discussed, Mr. Claure’s individual performance factor was increased to 125% in recognition of his substantial contributions to the Company in fiscal year 2017.

Executive Compensation

(2) Mr. Combes’s actual fiscal year 2017 STIC plan target opportunity was $698,630, reflecting a proration of his target opportunity in light of his start date of January 6, 2018. Pursuant to the terms of his employment agreement, Mr. Combes’s payout was equal to the greater of prorated target or actual performance.

(3) Mr. Gracia’s fiscal year 2017 STIC plan target opportunity reflects the increase in his base salary effective November 11, 2017. As previously discussed, Mr. Gracia’s individual performance factor was increased to 125% in recognition of his substantial contributions to the Company in fiscal year 2017.

(4) Mr. Robbiati’s actual fiscal year 2017 STIC plan target opportunity was $838,356, reflecting a proration of his target opportunity for the number of days he was employed during fiscal year 2017. Pursuant to the 2017 STIC plan design, Mr. Robbiati’s individual performance factor defaulted to 75%.

LTIC Plan

Our LTIC plan is designed to encourage retention, link payment of performance-based awards to achievement of financial and operational objectives critical to our long-term success, and create a commonality of interests between our executives and our stockholders. By dovetailing with the STIC plan, our LTIC plan is also intended to create balance between short-term, or annual, performance goals and longer-term objectives that are critical to growing and sustaining stockholder value. Under the 2017 LTIC plan, each of our named executive officers (other than Mr. Claure) is eligible to earn equity-based awards subject to performance-based and/or service-based vesting conditions. In addition, as described in our 2016 proxy statement, the special TIA award granted to Mr. Claure in the fiscal year ended March 31, 2016 served as a three-year award. Accordingly, Mr. Claure did not receive an equity award in fiscal years 2016 and 2017, and Mr. Claure is not entitled to LTIC awards for 2018 based on the terms of this 2015 TIA award.

2017 LTIC Plan.The participating named executive officers’ fiscal year 2017 LTIC plan awards were granted under our Amended and Restated 2015 Omnibus Incentive Plan in the form of time-based restricted stock units (RSUs), performance-based RSUs (pRSUs), and stock options to emphasize the imperative of achieving long-term growth and alignment with stockholder interests. Stock options have value only if Sprint’s stock price increases after the grant date. Allocations of the three types of awards granted under our 2017 LTIC plan are as follows:

Type of Award	Percent of 2017 LTIC Plan Opportunity	Vesting
Time-based RSUs	30%	Generally vest ratably on each of May 24, 2018, 2019 and 2020
Performance-based RSUs	50%	Generally vest on May 24, 2020, withearn-out allocated to a single three-year performance period (April 1, 2017 through March 31, 2020) subject to achievement of certain performance-based vesting conditions
Time-based stock options	20%	Generally vest ratably on each of May 24, 2018, 2019 and 2020 Have value only if the Company’s stock price increases from the date of grant

Executive Compensation

For fiscal year 2017, each of our named executive officers (except for Mr. Claure, who was not eligible to receive an LTIC plan award for fiscal year 2017 as described above) was granted a target opportunity under the 2017 LTIC plan, as follows:

Named Executive Officer	2017 LTIC Plan Target Opportunity ($)
Claure	—
Combes	2,500,000(1)
Cano	1,625,000
Crull	2,000,000
Gracia	1,200,000
Former Executive Officer
Robbiati	1,500,000

(1) Pursuant to his employment agreement, Mr. Combes’s fiscal year 2017 LTIC plan target opportunity was set at $2,500,000 for fiscal year 2017.

The Compensation Committee typically grants equity awards under the LTIC plan in May, following a review of the fiscal year budget and an assessment of the factors critical to driving long-term stockholder value. Grants of awards under the 2017 LTIC plan were made in May 2017 (January 2018 for Mr. Combes), with earn-outs of pRSUs granted under the 2017 LTIC plan for the three-year performance period from April 1, 2017 through March 31, 2020 noted below.

Performance-Based RSUs. Similar to our STIC plan, the pRSUs granted under our LTIC plan provided for a payment equal to the named executive officer’s targeted opportunity for such awards (set at a percentage of his total LTIC plan opportunity) only if our actual results meet the targets for each completed performance period. Anearn-out of pRSUs in excess of a named executive officer’s targeted opportunity may be made if our actual performance exceeds the targeted objectives (but capped at 200% of the target), anearn-out below targeted opportunity may be made if our actual performance is below the target objectives but exceeds the minimum threshold level, and noearn-out would be made if our actual performance does not exceed the minimum threshold level. Earn-outs achieved under the LTIC plan are subject to the Compensation Committee’s negative discretion. As described in more detail in our discussion below under “Tax Deductibility of Compensation,” changes made by the 2017 Tax Cuts and Jobs Act generally eliminated the tax deduction exception for performance-based compensation under Section 162(m) of the IRC. We, however, intend to continue to grant performance awards.

Based on feedback we received in early 2017 from certain of our largest stockholders (other than SoftBank, which already has representation on our board), our Compensation Committee made changes in the design of our 2017 LTIC plan to establish pRSU objectives covering a single three-year performance period rather than our past practice of setting three individualone-year performance periods. This change was designed to further focus our executives on achieving longer-term objectives to drive long-term stockholder returns. Accordingly, grants of pRSUs under our 2017 LTIC plan were allocated to one single three-year performance period (April 1, 2017 through March 31, 2020) and in general will vest, if at all, on May 24, 2020 based on the achievement of the performance-based vesting conditions described below. Accordingly, given the focus on profitability

  Notice of Annual Meeting and Proxy Statement  |  31

Executive Compensation

growth, cash flow and subscriber growth for the three-year performance period, the Compensation Committee adopted objectives for the pRSUs for the three-year performance period that were weighted among EBIT Compound Annual Growth, Adjusted Free Cash Flow and End of Period (EOP) Market Share:

With respect to the EBIT Compound Annual Growth Rate metric, the threshold, target and maximum EBIT growth percentage goals for each year of the three-year performance period were established at the beginning of the three-year performance period. For each year of the three-year performance period, the base-year number over which the annual EBIT growth rate performance is measured is the final actual EBIT of the preceding fiscal year. At the end of the three-year performance period ending March 31, 2020, the calculated payout percentages from each of the three years’ performance results are averaged to determine the actual share delivery.

2016 and 2015 LTIC Plans.Prior to implementing the 2017 LTIC plan in fiscal year 2017, our recent practice was to establishpRSU objectives covering three individualone-year performance periods. Accordingly, grants of pRSUs under our 2016 and 2015 LTIC plans were allocated to each of three separate fiscal year performance periods. The objectives established for the second and third annual performance periods of the 2016 and 2015 LTIC plans, respectively, covering our 2017 fiscal year, were generally consistent with the objectives established for the 2017 LTIC plan as discussed above, albeit modified to account for the differing performance periods of the 2016 and 2015 LTIC plans as noted above:

Objective	Fiscal 2017 Minimum Threshold		Fiscal 2017 Target Goal		Fiscal 2017 Maximum Goal		Actual Results		Earn-Out Percentage
FY 2017 EBIT		$2,200,000,000		$2,347,000,000		$2,847,000,000		$2,727,000,000	176.0%
FY 2017 Adjusted Free Cash Flow		$4,405,000,000		$4,551,000,000		$5,051,000,000		$5,269,000,000	200.0%
EOP Market Share (as of   March 31, 2018)		12.47%		12.81%		13.07%		12.39%	0%
Achievement									125.84%

Accordingly, for the fiscal year 2017 performance period under the 2016 and 2015 LTIC plans, cumulative results for the 2016 and 2015 LTIC plan for fiscal year 2017 were as follows, with the earned pRSUs generally scheduled to vest three years from grant date: 8,685; 160,713; 70,952; and 93,718 for Messrs. Cano, Crull, Gracia and Robbiati, respectively. Mr. Claure did not participate in the 2016 and 2015 LITC plans for the reasons discussed above, Mr. Combes did not participate in the 2016 and 2015 LTIC plans because he was hired in January 2018, and Mr. Cano did not participate in the 2015 LTIC plan because he was hired in February 2017.

Executive Compensation

Turnaround Incentive Awards

In fiscal year 2015, Sprint granted TIA awards to Messrs. Claure, Crull, Gracia and Robbiati. In fiscal years 2016 and 2017, Sprint granted TIA awards to Messrs. Cano and Combes, respectively, in connection with their arrivals at Sprint.

The TIA awards, granted in the form of performance-based RSUs, can be earned based on the achievement of specified volume-weighted average prices of our common stock during regular trading on the NYSE over any150-calendar day period (VWAP Prices) during the performance periods specified in the tables below. The Compensation Committee determined to grant the TIA awards in order to recruit and retain executive officers and focus the leadership team on a common set of objectives driven by the six pillars described above. In addition, all of Sprint’snon-executive employees received TIA awards in fiscal year 2016 or, in the case ofnon-executive employees hired after September 21, 2016 and employed as of March 31, 2017, a TIA award was granted in fiscal year 2017, to create a cohesive performance incentive among our employees and our executives.

Payouts for the TIA awards granted to the following named executive officers in fiscal years 2015 and 2016 are determined as follows:

Named Executive Officer	Performance Period	Target Number   of Shares Under TIA Awards	Highest 150-Day VWAP Price During  Performance Period	Percentage of Earned TIA Awards
Claure	6/1/2015 – 5/31/2019	10,000,000	Less than $7.00	0%
Cano	2/2/2017 – 5/31/2019	1,750,000	$7.00	25%
Crull	6/1/2015 – 5/31/2019	2,500,000	$7.50	50%
Gracia	1/2/2016 – 5/31/2019	312,500	$8.00	100%
Former Executive Officer			Greater than or equal to $10.00	120%
Robbiati	6/1/2015 – 5/31/2019	1,250,000

Payouts for the TIA award granted to Mr. Combes in fiscal year 2017 are determined as follows:

Named Executive Officer	Performance Period	Target Number   of Shares Under TIA Award	Highest 150-Day VWAP Price During  Performance Period	Percentage of Earned TIA Awards
Combes	1/30/2018 – 5/31/2021	3,000,000	Less than $8.00	0%
			$8.00	100%
			Greater than or equal to $10.00	120%

Executive Compensation

The TIA awards granted to our named executive officers, except for those granted to Mr. Combes, have been earned at a 100% level because we achieved the applicable VWAP Price target, but remain subject to certain vesting requirements based on the schedule set forth below. Although 100% of the target number of shares under the TIA awards have already been earned, 120% of such TIA awards can still be earned if the Company’s stock price equals or surpasses the maximum VWAP Price target of $10.00 during the remainder of the applicable performance period.

Named Executive Officer	Vesting Schedule
Claure	50% on August 7, 2019 and 50% on August 7, 2020
Combes	100% on May 31, 2022
Cano	50% on February 1, 2020 and 50% on February 1, 2021
Crull	50% on May 31, 2019 and 50% on May 31, 2020
Gracia	50% on February 3, 2020 and 50% on February 3, 2021
Former Executive Officer
Robbiati	50% on August 31, 2019 and 50% on August 31, 2020(1)

(1) In connection with his termination of employment, Mr. Robbiati is eligible to receive apro-rata number, based on his termination date of January 31, 2018, of earned shares on his regularly scheduled vesting dates.

Other Components of Executive Compensation

Our named executive officers’ total rewards opportunities consisted of a number of other elements important to our compensation philosophy for fiscal year 2017 of attracting, retaining, and motivating our named executive officers.

Employee Benefit Plans and Programs. Our compensation program includes a comprehensive array of health and welfare benefits in which our eligible employees, including our named executive officers, are eligible to participate on terms and conditions substantially similar to those that apply for our other employees. We pay all of the costs for some of these benefit plans, and participants contribute a portion of the cost for other benefit plans. We also maintain an employee stock purchase plan, in which our eligible employees, including our named executive officers, are eligible to participate.

Retirement Program. Our retirement program consists of the Sprint Corporation 401(k) Plan, which provided participants with a fixed matching contribution on up to 50% on the first 4% of eligible compensation through December 31, 2017, and effective January 1, 2018, the match was increased to provide a fixed matching contribution on up to 100% of the first 3% of eligible compensation, to help build financial security for their future. The Compensation Committee also has authority to approve an additional discretionary match based on a formula determined by it. For fiscal year 2017, the Compensation Committee set a formula so that if the Company exceeded the fiscal year 2017 EBIT target for theone-year performance period pRSUs, then ten percent of the excess earnings could be utilized to fund a discretionary matching contribution with a maximum contribution equal to four percent of a participant’s eligible compensation. The Company achieved earnings in excess of the fiscal year 2017 EBIT target, which provided for a potential discretionary match of $42.6 million. The Compensation Committee utilized negative discretion to approve a discretionary

Executive Compensation

match in the amount of approximately $13.8 million, equal to 100 percent of participant contributions up to four percent of a participant’s eligible compensation not to exceed $500 per participant. The amount of any matching contributions made to participating named executive officers is included in the “All Other Compensation” column of the Fiscal Year 2017 Summary Compensation Table below.

Deferred Compensation.Certain employees, including our named executive officers, are offered the opportunity to participate in the Sprint Corporation Deferred Compensation Plan, a nonqualified and unfunded plan, under which employees may defer to future years the receipt of certain compensation in addition to that eligible under the 401(k) plan. Participants may elect to defer up to 50% of base salary and up to 75% of STIC plan payments. We believe this plan helps attract and retain executives by providing them with another tax efficient method to plan for retirement. In addition, executive officer participation in this plan might be able to enable a tax deduction by us for post-termination compensation. None of our named executive officers except Mr. Cano participated in the plan during fiscal year 2017.

Personal Benefits and Perquisites. The personal benefits and perquisites that we provide to our named executive officers are intended to promote executive retention and to allow our executives to maximize their focus on Sprint. In accordance with the Company’s relocation policy applicable to senior executives, the Company provided relocation benefits to executives in connection with the hiring of such executives from various locations. These benefits are summarized in footnote five to the Fiscal Year 2017 Summary Compensation Table below. Pursuant to his employment agreement, Mr. Claure is permitted to use up to six hours of flight time per month for personal travel on our corporate aircraft for security and efficiency purposes. Any unused hours are carried over to the next month, and Mr. Claure is required to pay the full incremental cost (but not the fixed cost) calculated pursuant to federal aviation regulations associated with personal use of the aircraft to the extent he exceeds his monthly allotted flight time (plus carryover hours). Mr. Claure is also permitted to have his family or guests accompany him on the corporate aircraft for business and personal travel.

Security Program.To promote the safety of certain of our executive officers while not at our offices, we commissioned a security study in 2017. As a result of this study, and because of the high visibility of the Company, the Compensation Committee has authorized a security program for Mr. Claure to address safety concerns due to specific threats to his safety arising directly as a result of his position with the Company. We require that the executive accept such personal security protection because we believe it is in the best interests of the Company and its stockholders that the executive not be vulnerable to security threats to the executive or members of his family. We also believe that the costs of this overall security program are appropriate and necessary. Although we do not consider Mr. Claure’s overall security program to be a perquisite for his benefit for the reasons described above, the costs related to personal security for Mr. Claure at his residence and during personal travel are reported in the “All Other Compensation” column of the Fiscal Year 2017 Summary Compensation Table. The Compensation Committee periodically reviews the amount and nature of executive officers’ security expenses.

Severance Benefits. Pursuant to their employment agreements, our named executive officers are entitled to certain severance benefits upon a qualifying termination of employment that is not in connection with a change in control. We provide these benefits because they are market competitive and assist us in attracting key executives. For more information, please see “Fiscal Year 2017 Potential Payments upon Termination of Employment or Change in Control.”

  Notice of Annual Meeting and Proxy Statement  |  35

Executive Compensation

Change in Control. If a transaction that could result in a change in control were under consideration, such as the contemplated merger withT-Mobile, we expect that our named executive officers would face uncertainties about how the transaction may affect their continued employment with us. We believe it is in our stockholders’ best interest if our named executive officers remain employed and focused on our business through any transition period following a change in control and remain independent and objective when considering possible transactions that may be in stockholders’ best interests but possibly result in the termination of their employment. Our change in control benefits accomplish this goal by providing each eligible named executive officer with a meaningful severance benefit in the event that a change in control occurs and, within a specified time period of the change in control, his employment is involuntarily terminated without “cause” or voluntarily terminated for “good reason.”

The Sprint Corporation Change in Control Severance Plan, which we refer to as the CIC Plan, provides severance benefits to a select group of senior executives, including our named executive officers, in the event of a qualified termination of employment in connection with a transaction that results in a change in control. Any of these benefits payable would be reduced to the extent of any severance benefit otherwise available under any other applicable policy, program, agreement, or plan so that there would be no duplication of benefits. We believe that the benefits upon termination in connection with a change in control to which our named executive officers are entitled, as described in “Fiscal Year 2017 Potential Payments upon Termination of Employment or Change in Control,” are likewise competitive within our peer group.

Employment Agreements and Other Decisions

We have employment agreements with each of our named executive officers. Discussion of the material terms of our employment agreements with our named executive officers can be found in the tabular and narrative discussion under “Fiscal Year 2017 Potential Payments upon Termination of Employment or Change in Control.”

Sign-on and Relocation Bonuses.In connection with his appointment as our President and CFO, Mr. Combes received a $600,000 relocation bonus for establishing a new residence in the Overland Park, Kansas area in accordance with the terms of his employment agreement, which is subject to repayment if his employment with us terminates under certain circumstances prior to January 6, 2020.

Departure of Mr. Robbiati. Mr. Robbiati’s employment with us terminated on January 31, 2018. Pursuant to the terms of his employment agreement, he was entitled to certain severance payments and benefits, as further described in the narrative discussion under “Fiscal Year 2017 Potential Payments upon Termination of Employment or Change in Control.”

Setting Executive Compensation

Role of Compensation Consultant and Executive Officers

The Compensation Committee has retained Frederic W. Cook & Co., Inc. (FW Cook) as its independent compensation consultant. FW Cook provides no services to us other than advisory services for executive and director compensation and has no other relationships with Sprint. FW Cook works with management only at the request and under the direction of the Compensation Committee and only on matters for which the Compensation Committee has oversight responsibility.

36  |  Notice of Annual Meeting and Proxy Statement  

Executive Compensation

The Compensation Committee has assessed the independence of FW Cook, as required under NYSE listing rules. The Compensation Committee has also considered and assessed all relevant factors, including those required by the SEC that could give rise to a potential conflict of interest with respect to FW Cook during fiscal year 2017. Based on this review, the Compensation Committee did not identify any conflict of interest raised by the work performed by any advisors to the Compensation Committee.

Representatives of FW Cook attend Compensation Committee meetings at the Compensation Committee’s request and provide guidance to the Compensation Committee on a variety of compensation issues. The primary point of contact at FW Cook frequently communicates with the chair of the Compensation Committee and interacts with all Compensation Committee members without management present.

FW Cook has reviewed the compensation components and levels for our named executive officers and advised the Compensation Committee on the appropriateness of our compensation programs, including our incentive and equity-based compensation plans, retention incentives, and proposed employment agreements, as these matters arose during fiscal year 2017. The Compensation Committee has directed that FW Cook provide this advice taking into account our overall executive compensation philosophy as described above. FW Cook prepares the market comparison data discussed below, reviews the results with the Compensation Committee, and provides recommendations and guidance on the reasonableness of new compensation plans, programs, and arrangements.

In addition to its ongoing support of the Compensation Committee and continuous advice on compensation design, levels, and emerging market practices, FW Cook annually conducts a comprehensive review of our overall executive compensation program, including direct and indirect elements of compensation, to ensure that the program operates in support of our short- and long-term financial and strategic objectives and that it aligns with evolving corporate governance “best practices.”

Our CEO periodically discusses the design of, and makes recommendations with respect to, our compensation programs and the compensation levels of our other named executive officers and certain key personnel with the Compensation Committee. Our CEO does not make recommendations to the Compensation Committee with regard to his own compensation; rather, FW Cook provides the Compensation Committee with an annual report on CEO compensation and a range of alternatives with regard to potential changes.

Process for Setting Executive Compensation

The Compensation Committee annually reviews the compensation packages of our named executive officers in the form of “tally sheets.” These tally sheets value each component of compensation and benefits, including a summary of the outstanding equity holdings of each named executive officer as of fiscalyear-end and the value of such holdings at various assumed stock prices. The tally sheets also set forth the estimated value that each of our named executive officers would realize upon termination under various scenarios.

The Compensation Committee uses these tally sheets when considering adjustments to base salaries and awards of equity-based or other remuneration and in establishing incentive plan target opportunity levels as follows:

✓ Comparing each named executive officer’s total compensation against a similar position in our peer group as a market check;

  Notice of Annual Meeting and Proxy Statement  |  37

Executive Compensation

✓ Understanding the impact of decisions on each individual element of compensation on total compensation for each named executive officer; and

✓ Ensuring that equity compensation represents a portion of each named executive officer’s total compensation that is in line with our philosophy of motivating the executives and aligning their interests with those of our stockholders.

Although the Compensation Committee reviews and considers the amounts realizable by our named executive officers under different termination scenarios, including those in connection with a change in control, as well as the current equity-based award holdings, these are not the primary considerations in the assessment and determination of annual compensation for our named executive officers.

Use of Market Comparison Data

To assist in setting total compensation levels that are reasonably competitive, the Compensation Committee annually reviews market trends in executive compensation and a competitive analysis prepared by FW Cook. This information is derived from the most recent proxy statement data of companies in a peer group of telecommunications and high-technology companies and, where limited in its functional position match to our executives, is supplemented with data on our peer group from a published compensation survey prepared by Willis Towers Watson, as tailored for Sprint, of approximately 47 participating industry companies all with revenues exceeding $25 billion. The compensation data, and not the identity of the individual companies participating in the surveys for this database, was generally the most significant factor considered by the Compensation Committee with respect to its fiscal year 2017 executive compensation decisions.

Taking into consideration the recommendations of FW Cook, the Compensation Committee determines companies for our peer group based on similarity of their business model and product offerings as well as comparability from a size perspective, including annual revenue, market capitalization, net income, enterprise value and number of employees. Accordingly, the Compensation Committee approved the use of the following 13 companies for its fiscal year 2017 executive compensation market comparison analysis:

AT&T, Inc.; CenturyLink, Inc.; Cisco Systems, Inc.; Comcast Corporation; DXC Technology Company; Intel Corporation; Motorola Solutions, Inc.; Qualcomm Incorporated; Texas Instruments Incorporated;T-Mobile US, Inc.; Charter Communications, Inc.; Verizon Communications Inc.; and Xerox Corporation.

This peer group did not change from fiscal year 2016, except that (1) EMC Corporation was removed from the group as a result of its acquisition by Dell Technologies, (2) Charter Communications, Inc. replaced Time Warner Cable, Inc. as a result of its acquisition of Time Warner Cable, Inc., and (3) DXC Technology Company, which was created by the merger of Computer Sciences Corporation and the Enterprise Services business of Hewlett Packard Enterprise, was added to the group. Sprint’s size positioning remains reasonable in relation to this group because Sprint’s revenue is between the median and 75^th percentile, which is balanced by Sprint’s market capitalization that is near the 25^th percentile. In addition, the group, as a whole, continues to represent a reasonable match to Sprint in business content. The Compensation Committee does not follow a specific formula in making its pay decisions but rather uses market comparison data as a frame of reference. The Compensation Committee does not target a specific percentile in the range of compensation data for each individual or for each component of compensation. The Compensation Committee exercises its judgment by taking into consideration a multitude of other important factors such as experience, individual performance, and internal pay equity in setting target compensation

levels, but actual payouts under our variable incentive plans are primarily determined based on formulaic outcomes. The Compensation Committee, however, considers unrealized appreciation in outstanding equity awards when reviewing each executive’s compensation.

Corporate Governance Highlights

We endeavor to maintain stockholder-friendly compensation practices, including with respect to our executive compensation program, which practices include the following:

Stockholder-Friendly Compensation Practices We   Embrace

Unfavorable Compensation Practices We Avoid

•     The majority of the compensation program provided to our senior executives is performance-based compensation •     70% of our long-term incentive value is delivered in performance-oriented awards (in other words, stock options and performance RSUs); 50% is delivered in performance-vesting awards; and only 30% of our long-term incentive program is delivered in time-based RSUs •     The peer group we use for market comparisons of compensation levels and practices appropriately reflects our size and industry of operations •     We provide few entitlements or elements ofnon-performance-based compensation •     We maintain a clawback provision in our incentive compensation programs under which we may recover cash and equity payouts •     We expect our senior executives to hold significant ownership in Sprint through meaningful stock ownership guidelines

•     Our severance benefits are positioned conservatively relative to market practices, with no benefit in excess of two times base salary plus annual incentive •     We do not provide excise taxgross-ups •     We do not employ single-trigger cash severance or equity acceleration •     We do not reprice underwater stock options without stockholder approval

Stock Ownership Guidelines

We have stock ownership guidelines for our named executive officers and other members of our senior management team. The board believes ownership by executives of a meaningful financial stake in Sprint serves to align executives’ interests with those of our stockholders. Our guidelines encourage our CEO to hold shares of our common stock with a value equal to five times his base salary and encourage the other continuing named executive officers to hold shares of our common stock with a value equal to three times or, in the case of Mr. Crull, one times, their respective base salaries. Eligible shares and share equivalents counted toward ownership consist of:

_• RSUs, including TIAs;

_• common stock, including shares purchased through our Employee Stock Purchase Plan;

_• intrinsic value (the excess of the current stock price over a stock option’s exercise price) of vested,in-the-money stock options; and

_• share units held in our 401(k) plan and various deferred compensation plans.

  Notice of Annual Meeting and Proxy Statement  |  39

Executive Compensation

Individuals subject to the stock ownership guidelines have five years beginning on the date on which the person becomes subject to the ownership guidelines to achieve the ownership requirement. None of our named executive officers has been with the Company for more than five years, and therefore is not yet subject to the ownership requirement. However, despite not yet being subject to the ownership requirement, all of our continuing named executive officers met the stock ownership guidelines as of March 31, 2018.

2017 StockholderSay-on-Pay Vote

We provide our stockholders with the opportunity to cast an annual advisory vote on named executive officer compensation (asay-on-pay proposal). At our 2017 annual meeting of stockholders, in anon-binding, advisory vote on the frequency of votes on named executive officer compensation, our stockholders voted in favor of an annual vote. Our board considered the outcome of this advisory vote and determined that we will hold futuresay-on-pay votes on an annual basis. Our board willre-evaluate this determination no later than after the next advisory vote regarding the frequency of futuresay-on-pay votes, which is required to occur no later than our 2023 annual meeting of stockholders.

At our 2017 annual meeting of stockholders, 99.3% of the votes cast on thesay-on-pay proposal were voted in favor of the proposal. The Compensation Committee considered the voting results at discussions among its members during the remainder of its fiscal year 2017 meetings, and the Compensation Committee believes this vote affirms stockholders’ support of Sprint’s approach to executive compensation. As a result of this consideration, we did not change our approach to named executive officer compensation in fiscal year 2017 solely in response to thesay-on-pay proposal results. The Compensation Committee expects to continue to consider the outcome of oursay-on-pay votes when making future compensation decisions for the named executive officers.

Tax Deductibility of Compensation

Section 162(m) of the IRC, as amended (Section 162(m)), limits to $1 million the amount of remuneration that we may deduct from our taxable income in any tax year with respect to certain executive officers (and, beginning in 2018, certain former executive officers). Section 162(m) was amended by the 2017 Tax Cuts and Jobs Act (TCJA) to generally repeal the rule that had allowed us to deduct from our taxable income without regard to the $1 million limit the full value of all “qualified performance-based compensation.” The new tax law, however, provides a transition rule for qualified performance-based compensation and any other compensation paid under written binding contracts in place on November 2, 2017 and not materially modified after that time (grandfathered awards). Our STIC plan, certain of our LTIC plan awards, and certain TIA awards were designed to potentially qualify as “qualified performance-based compensation” if certain requirements are met, including among other things if the maximum number of stock options or full value share awards and the maximum amount of cash performance-based remuneration that may be payable to any one executive officer has been disclosed to and approved by stockholders prior to the award or payment.

The Compensation Committee has generally considered Section 162(m) deductibility in designing our compensation program and incentive-based compensation plans. Executive compensation tax deductions unquestionably have, however, been limited under the TCJA, and the Compensation Committee makes no assurance that any performance-based compensation, or compensation paid after termination of service, will be fully deductible for federal income tax purposes. Moreover, even if the Compensation Committee intended to grant compensation that qualifies as “qualified performance-based compensation” under the transition rule of Section 162(m) as amended, Sprint cannot guarantee that such compensation will so qualify or ultimately will be deductible.

40  |  Notice of Annual Meeting and Proxy Statement  

Executive Compensation

The awards under our 2017 STIC plan, pRSUs under the LTIC plan, and TIAs were designed so that they may be able to qualify as “qualified performance-based compensation” under Section 162(m). The pRSUs for the first annual performance period of the 2015 LTIC granted to Mr. Gracia on February 3, 2016 were not intended to be qualified performance-based compensation under Section 162(m). The pRSUs for the first annual performance period of the 2016 LTIC plan and a portion of the TIA awards granted to Mr. Cano on February 2, 2017 were not intended to be qualified performance-based compensation under Section 162(m). In addition, all awards made to Mr. Combes were not intended to be qualified performance-based compensation because he was hired after November 2, 2017.

For the 2017 STIC plan, the Compensation Committee comprised of Mr. Bethune and Adm. Mullen established Section 162(m) objectives for the named executive officers potentially subject to Section 162(m) at a small fraction of a percentage of our adjusted operating income (approximately 1% or less) for the performance cycle. Under the tax laws applicable before 2018 (which still generally apply to any grandfathered awards), the Compensation Committee is precluded from exercising upward discretion to the payout achieved under the Section 162(m) objectives. The Compensation Committee then exercised its negative discretion to make payments under the 2017 STIC plan at levels below the payout achieved under the Section 162(m) objectives for the fiscal year 2017 performance period, as guided by the performance metrics discussed under “Key Fiscal Year 2017 Compensation Decisions—2017 STIC Plan.”

For the three-year performance period under the 2017 LTIC plan, the second annual performance period under the 2016 LTIC plan, and the third annual performance period under the 2015 LTIC plan, the Compensation Committee established a Section 162(m) objective for the pRSUs for the named executive officers potentially subject to Section 162(m) based on cumulative adjusted operating income during the performance cycle.Under the tax laws applicable to any grandfathered awards, the Compensation Committee is precluded from exercising upward discretion to the payout achieved under the Section 162(m) objective. The Compensation Committee then exercised its negative discretion to set the performance adjustment for the second annual performance period of the 2016 LTIC plan and the third annual performance period under the 2015 LTIC plan at levels below theearn-out achieved under the Section 162(m) objective for the performance period, as guided by the performance metrics discussed under “Key Fiscal Year 2017 Compensation Decisions—LTIC Plan.”

Compensation Committee Report

The Compensation Committee has reviewed and discussed Sprint’s Compensation Discussion and Analysis with management. Based on these reviews and discussions, the Compensation Committee recommended to the board that Sprint’s Compensation Discussion and Analysis be included in this proxy statement and Annual Report on Form10-K for the fiscal year ended March 31, 2018.

Relationship of Compensation Practices to Risk Management

We annually assess whether there are any risks arising from our compensation policies and practices for our employees and factors that may affect the likelihood of excessive risk taking. Based on our annual review, we have concluded that our compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on the Company. In addition, the Compensation Committee’s independent consultant, FW Cook, annually considers risk in all aspects of the plans in which our executives participate and advises the Compensation Committee accordingly. For fiscal year 2017, FW Cook confirmed its view that there are no aspects of the programs described in the preceding Compensation Discussion and Analysis that create an incentive to take risks that are reasonably likely to have a material adverse effect on the Company.

For the 2017 time-based RSU awards, the value represents the aggregate grant date fair value computed in accordance with FASB ASC Topic 718. The time-based RSUs generally vest ratably on each of May 24, 2018, 2019 and 2020.

Amounts for the fiscal year 2017 portion of the pRSUs granted represent the aggregate grant date fair value computed in accordance with FASB ASC Topic 718. The pRSUs granted under the 2015 LTIC plan are reported based on target opportunity (in other words, probable outcome of the performance conditions) and generally vested on May 20, 2018, subject to achievement of the applicable performance conditions. Assuming maximum levels of performance are achieved, the aggregate grant date fair value would be $867,075; $187,812; and $791,329 for Messrs. Crull, Gracia and Robbiati, respectively, for the 2015 LTIC plan pRSUs. The pRSUs granted under the 2016 LTIC plan are reported based on target opportunity (in other words, probable outcome of the performance conditions) and vest generally on May 13, 2019, subject to achievement of the applicable performance conditions. Assuming maximum levels of performance are achieved, the aggregate grant date fair value would be $113,331; $1,229,957; $737,980; and $922,476 for Messrs. Cano, Crull, Gracia and Robbiati, respectively, for the 2016 LTIC plan pRSUs. The pRSUs granted under the 2017 LTIC plan are reported based on target opportunity (in other words, probable outcome of the performance conditions) and vest generally on May 24, 2020, subject to achievement of the applicable performance conditions. Assuming maximum levels of performance are achieved, the aggregate grant date fair value would be $2,324,257; $1,576,977; $1,940,893; $1,164,539; and $1,455,666 for Messrs. Combes, Cano, Crull, Gracia, and Robbiati, respectively, for the 2017 LTIC plan pRSUs. For more information regarding the 2017 LTIC plan, see “Executive Compensation—Key Fiscal Year 2017 Compensation Decisions—LTIC Plan.”

For Mr. Combes’s 2017 TIA award, the value represents the aggregate grant date fair value computed in accordance with FASB ASC Topic 718. The 2017 TIA RSUs are reported based on the probable outcome of achieving the volume-weighted average price target over any consecutive150-calendar days during the applicable performance period as noted above. If we were to achieve or exceed a $10.00 VWAP during the performance period, the maximum number of RSUs that could be earned pursuant to the 2017 TIA awards would be 3,600,000 and the aggregate grant date fair value would be $12,924,000.

See “—Note 2—Summary of Significant Accounting Policies” in Sprint’s Annual Report onForm 10-K for the fiscal year ended March 31, 2018, for more information regarding the assumptions upon which the above amounts are based.

(2) None of the amount reported in this column has been reported in Summary Compensation Tables for prior fiscal years.

(3) The original grant date fair value of the 2017 portion of the pRSUs granted under the 2015 and 2016 LTIC plans are included in the “Stock Awards” column of the Fiscal Year 2017 Summary Compensation Table and summarized in footnote 2 thereto. The original grant date fair value of the time-based RSUs and the 2015 and 2016 portions of the pRSUs granted under the 2015 and 2016 LTIC plans were previously reported in Summary Compensation Tables for prior fiscal years. For more information regarding these awards, see “—RSU and pRSU Awards” below.

Deferred Compensation Plan

Certain employees, including our named executive officers, are offered the opportunity to participate in the Sprint Corporation Deferred Compensation Plan, a nonqualified and unfunded plan, under which employees may defer to future years the receipt of certain compensation in addition to that eligible under the 401(k) plan. For fiscal year 2017, the plan permitted participants to defer up to 50% of base salary and up to 75% of STIC plan payments.

Compensation deferred by participants is credited to a bookkeeping account that represents our unsecured obligation to repay the participant in the future. Participants elect to allocate deferred contributions among one or more hypothetical investment options, which include one option that tracks our common stock and other options that track broad-based bond and equity indices. Participants may change hypothetical investment elections only four times a year and at least three months must elapse between each change. Under the plan, the amount of our unfunded obligation is determined by tracking the value in the bookkeeping account according to the performance of the hypothetical investments.

On January 31, 2018, Mr. Robbiati vested in 65,106 time-based RSUs, 48,192 pRSUs under the 2015 portion of the 2015 LTIC plan, 48,363 time-based RSUs, 66,873 pRSUs under the 2016 portion of the 2015 LTIC plan, 42,584 pRSUs under the 2017 portion of the 2015 LTIC plan, 77,954 pRSUs under the 2016 portion of the 2016 LTIC plan and 51,134 pRSUs under the 2017 portion of the 2016 LTIC plan.

Fiscal Year 2017 Potential Payments upon Termination of Employment or Change in Control

Upon a termination of employment at the end of the fiscal year ended March 31, 2018, due to a resignation without good reason or termination by us with cause, our named executive officers would be entitled to only those payments and benefits provided to all of our salaried employees on anon-discriminatory basis (accrued benefits), including:

_• accrued salary and vacation pay; and

_• payment of any vested balances or accrued benefits under our 401(k) Plan, Sprint Corporation Deferred Compensation Plan, Qualified Plan, and SERP.

In addition, although none of our named executive officers satisfied the age and service requirements as of the end of the fiscal year ended March 31, 2018, if they had been terminated and their termination had been at their normal retirement, they would be entitled to receive (consistent with benefits provided to all our salaried employees) accelerated vesting on options outstanding for at least one year andpro-rata vesting on RSUs outstanding for at least two years. Unvested RSUs will be forfeited as of the separation from service date. For more information on the retirement and deferred compensation benefits available to our named executive officers, see “Other Components of Executive Compensation” above.

Pursuant to the terms of our named executive officers’ respective employment agreements, equity award agreements and/or our Change in Control Severance Plan (again, the CIC Plan), upon an involuntary termination without cause or resignation for good reason (whether in connection with a change in control or not) or a termination in connection with their disability or death, our named executive officers would be entitled to not only their accrued benefits noted above, but other payments and benefits as set forth in more detail below.

While each of the applicable employment agreements and the CIC Plan set forth relevant definitions in full, generally:

“Change in control” generally means: (1) the acquisition by a person or group, excluding SoftBank or its controlled affiliates, of 30% or more of Sprint’s voting stock; (2) a change in the composition of a majority of our directors; (3) the close of a merger, reorganization, business combination or similar transaction after which: (a) Sprint’s stockholders do not hold more than 50% of the combined entity, (b) the members of Sprint’s board do not constitute a majority of the directors of the combined entity, or (c) a person or group holds 30% or more of the voting securities of the combined entity; (4) Sprint ceasing to have equity securities trading on a national securities exchange; or (5) the liquidation or dissolution of Sprint.

  Notice of Annual Meeting and Proxy Statement  |  53

Executive Compensation

We generally have “cause” to terminate the employment of a named executive officer involuntarily if that officer (1) materially breaches his employment agreement, (2) fails to perform his duties, (3) intentionally acts in a manner that is injurious to us, (4) is convicted of (or pleads no contest to) any felony, (4) commits any intentional or knowing violation of any material antifraud provision of federal or state securities laws, (5) committed any willful misconduct or criminal activity, (6) is abusing alcohol or prescription drugs in a manner that affects work performance, (7) uses illegal drugs, or (8) violates our code of conduct.

“Good reason” generally means the occurrence of any of the following without the named executive officer’s consent:

_• our material breach of the employment agreement; a reduction in salary or short-term incentive compensation target opportunity, except foracross-the-board reductions; certain relocations; or, for Mr. Claure and Mr. Combes, a material diminution in responsibilities or authorities or a material adverse change in his position or title (except as specifically noted in Mr. Claure’s employment agreement); or

_• in connection with a change in control:

^¡  a significant and adverse reduction of a named executive officer’s duties or responsibilities or organizational status;

^¡  the failure to provide a long-term incentive compensation opportunity comparable to other senior executives or a greater than 10%across-the-board reduction to any of base salary or short- or long-term incentive compensation opportunities;

^¡  reduction in the aggregate employee benefits, except foracross-the-board reductions; or

^¡  our failure to obtain an agreement from a successor to assume the employment agreement or the CIC Plan.

As a condition to a named executive officer’s entitlement to receive the amounts below, except for vested retirement or death benefits, such officer would have been:

_• required to execute a release in favor of us;

_• subject to confidentiality andnon-disparagement provisions on a permanent basis following the termination of their employment; and

_• for the duration of their respective payment periods, prohibited from:

^¡  engaging in certain employment activities with a competitor of ours;

^¡  soliciting our employees and certain other parties doing business with us to terminate their relationship with us; and

^¡  soliciting or assisting any party to undertake any action that would be reasonably likely to, or is intended to, result in a change in control or seek to control our board.

If the named executive officer breached any of these obligations, he would have no rights in, and we would have no obligation to provide, any severance benefits yet to be paid or provided under his employment agreement and any outstanding equity-based award granted under his employment agreement would have terminated immediately.

Executive Compensation

The following table and footnotes, along with the narrative below, describe the potential payments and benefits that would be provided to our named executive officers other than Mr. Robbiati (whose employment terminated on January 31, 2018) upon each respective hypothetical March 31, 2018 termination of employment scenario, based on the closing price of a share of our common stock of $4.88 on March 29, 2018. TheNon-CIC column shows the amounts due to each named executive officer (other than Mr. Robbiati) in the event of his involuntary termination without cause or resignation with good reason on March 31, 2018. Amounts in the CIC column assume a qualifying termination in connection with a change in control occurring on March 31, 2018.

Executive Compensation

(1) The CIC Plan provides that if the payments and benefits provided to an executive under the CIC Severance Plan or any other plan or agreement would constitute an “excess parachute payment” for purposes of Section 280G of the IRC, the executive would either have his or her payments and benefits reduced to the highest amount that could be paid without triggering excise taxes under Section 4999 of the IRC; or, if greater, receive theafter-tax amount of his or her payments and benefits taking into account the excise taxes and any other applicable federal, state and local taxes. Amounts do not take into account any possible reduction due to the effects of Section 280G of the IRC.

(2) Includes stock options, RSUs, and pRSUs (including TIA awards). The value of options is based on the intrinsic value of the options, which is the difference between the exercise price of the option and the market price of our shares on March 31, 2018, multiplied by the number of options, and the value of RSUs and pRSUs is based on the market value of our stock on March 31, 2018, multiplied by the target number of RSUs or pRSUs, as applicable.

Generally, if an involuntary not for cause termination occurs during the CIC protection period (which generally covers the6-month period before a change in control through the18-month period ending following a change in control), then RSUs and pRSUs become 100% vested as of termination date, with application of any performance adjustment applied to pRSUs allocated to performance periods ending on or before the termination date; and paid at target performance for pRSUs allocated to periods thereafter. Stock options vest in full on termination date and vested stock options remain exercisable for 90 days. If an involuntary not for cause termination occurs outside of the CIC protection period, then RSUs or pRSUs are prorated as of termination date, with application of any performance adjustment applied to pRSUs allocated to performance periods ending on or before the termination date. Unvested stock options are forfeited on termination date. Vested stock options remain exercisable for 90 days. Vested stock options remain exercisable for 90 days after severance ends.

For a termination due to disability, generally, outstanding stock options vest immediately and remain exercisable until the earlier of five years or the expiration date of the options, and RSUs and pRSUs vest immediately, with pRSUs deemed vested at target levels, subject to performance adjustment for pRSUs allocated to a performance period ending on or before the separation date.

For a termination due to death, generally, outstanding stock options vest immediately and remain exercisable until the earlier of 12 months or the expiration of the term of the option, and outstanding RSUs and pRSUs vest in full, with pRSUs deemed vested at target levels, subject to performance adjustment for pRSUs allocated to a performance period ending on or before the separation date.

Mr. Robbiati

Mr. Robbiati’s employment with us ended on January 31, 2018. He accrued, as a result of his involuntary termination without cause, payments and benefits of $1,600,000 in salary-based compensation, $2,604,245 inSTI-based compensation, $6,611,337 in equity-based (as described in footnote 2 above) compensation, $13,781 in benefits, and $35,000 in outplacement services, for a total of $10,864,363 to be paid over the course of his24-month payment period.

CEO Pay Ratio

Pursuant to SEC rules, we are required to disclose in this proxy statement the ratio of the annual total compensation of Mr. Claure (“CEO Compensation”), who served as our CEO for fiscal year 2017, to the median of the annual total compensation of all of our employees (excluding Mr. Claure) and those of our consolidated subsidiaries (“Median Annual Compensation”). We note that, due to our permitted use of reasonable estimates and assumptions in preparing this pay ratio disclosure, the disclosure may involve a degree of imprecision, and thus this pay ratio disclosure is a reasonable estimate calculated in a manner consistent with Item 402(u) of RegulationS-K using the data and assumptions described below. In this summary, we refer to the employee who received the Median Annual Compensation as the “Median Employee.” For purposes of this disclosure, the date used to identify the Median Employee was January 1, 2018 (the “Determination Date”).

We began by determining that we had 29,523 employees as of the Determination Date. As is permitted under the SEC rules, we eliminated 168 global employees (approximately 0.57% of our total population), which represented all of ournon-U.S. employees, from the data set. A list of the excluded employees and their respective countries is provided in the following table:

Country	No. of Employees	Country	No. of Employees	Country	No. of Employees	Country	No. of Employees	Country		No. of Employees
Argentina	2	China	4	India	16	Netherlands	6		Switzerland		1
Australia	7	Colombia	2	Italy	4	New Zealand	1		Taiwan		1
Austria	4	Denmark	2	Japan	10	Philippines	2		Thailand		1
Belgium	1	France	8	Korea	4	Russia	1		United Kingdom		25
Brazil	5	Germany	14	Malaysia	1	Singapore	12
Canada	11	Hong Kong	13	Mexico	7	Sweden	3

As permitted under SEC rules, to determine our Median Employee, we used a consistently applied compensation measure based on “taxable wages,” which consists of compensation as reported in Box 1 on FormW-2, for 2017. We annualized pay for permanent employees who commenced work during 2017, but avoided creating full-time equivalencies, based on reasonable assumptions and estimates relating to our employee compensation program. Next, we used a valid statistical sampling approach to identify employees who we expected were paid within a +/- 5% range of the estimated median taxable wage value. From this group we selected an employee who we felt was reasonably representative of our median employee, and determined that employee to be our Median Employee. We then determined the Median Employee’s Summary Compensation Table total compensation was $70,941. This includes $6,446 in employer-provided health and welfare benefits for the Median Employee. We determined the CEO’s compensation to be $6,395,042 (which includes $11,124 in employer-provided health and welfare benefits for the CEO not included in the Summary Compensation Table). Based upon this methodology, we estimate that the ratio of CEO Compensation to the Median Annual Compensation is 90:1.

Mr. Fisher is a member of the board of directors of SoftBank and Brightstar, which is a controlled affiliate of SoftBank. Mr. Claure is a member of the board of directors of SoftBank and an officer of certain of its affiliates. In this section, we refer to SoftBank, its controlled affiliates (other than Sprint), and Messrs. Son and Fisher as SoftBank Parties, or each a SoftBank Party.

Policy on Oversight of Related Party Transactions

Our board adopted, and the Audit Committee maintains, a written policy on the review and approval of transactions with related parties. The policy generally groups these transactions into two categories: (1) transactions requiring Audit Committee approval; and (2) certain ordinary course transactions that are deemedpre-approved by the Audit Committee after being reviewed and approved as appropriate by our related party transaction committee, which is comprised of members of management. This related party transaction committee also acts as a gatekeeper by reviewing and analyzing related party transactions prior to submission to the Audit Committee for review.

Generally, the Audit Committee deemspre-approved any transaction or series of transactions with a SoftBank Party that is entered into in the ordinary course of business and has substantially the same terms and conditions offered to or by third parties, or where the rates or charges involved are determined by competitive bid, as well as certaintri-party agreements.

During fiscal year 2017, Sprint incurred approximately $92.5 million in fees payable to Brightstar and Brightstar reimbursed Sprint for approximately $23 million in pass through costs. To facilitate this arrangement with Brightstar, Sprint extended a $1 billion credit line to Brightstar to assist with the purchasing and distribution by Brightstar of devices and under the credit line. Sprint and Brightstar, however, amended the credit line in July 2016, whereby (1) Brightstar sources devices through Sprint, and (2) the credit line described above was reduced from $1 billion to $700 million. No interest is payable under the credit line and no interest was paid during fiscal year 2017. The maximum amount that has been outstanding on the credit line was $890 million on December 15, 2014, the maximum amount that was outstanding on the credit line during fiscal year 2017 was $357 million on November 16, 2017, and the amount outstanding as of March 31, 2018 was approximately $161 million. During fiscal year 2017, the Audit Committee approved various amendments and modifications to the fourth-party logistics services arrangement, including: (1) in May 2017, approval of annual baseline revisions to cost to serve rates, performance baselines and device payment terms; (2) in August 2017, approval of a trial agreement pursuant to which Brightstar will provide dealer inventory/stock balancing services; and (3) in each of November 2017 and January 2018, approval of short-term extensions of the arrangement. Further, in January 2018, the Audit Committee approved the award of a revised Statement of Work to be entered into by and between Sprint and Brightstar regarding Brightstar’s provision of fourth-party logistics services.

On January 20, 2015, we entered into a series of ordinary course transactions between Sprint and Brightstar whereby Sprint would purchase handsets from Brightstar pursuant to the fourth-party logistics services arrangement described above. These purchases resulted from repurchasing product previously sold to Brightstar in order to fulfill Sprint’s inventory needs and third-party channel returns pursuant to the agreement. We incurred expenses payable to Brightstar of approximately $71 million pursuant to this arrangement during fiscal year 2017.

Effective August 1, 2015, Sprint and Brightstar entered into Statements of Work (Postpaid Buyback SOW and Postpaid Reverse SOW) pursuant to which Brightstar provides device buyback,trade-in technology, and related services. In February 2017, the Audit Committee approved a three year extension of these programs and, effective August 1, 2017, the Postpaid Buyback SOW and Postpaid Reverse SOW were amended to extend the terms until July 2020. For fiscal year 2017, Sprint incurred expenses payable to Brightstar of approximately $26.4 million and Brightstar incurred expenses payable to Sprint of approximately $38.2 million pursuant to the Postpaid Buyback SOW and Postpaid Reverse SOW.

Certain Relationships and Related Party Transactions

Effective August 14, 2017, Sprint and Brightstar entered into a Statement of Work (COS Accessories SOW) whereby Brightstar provides turnkey outsourcing of accessory sales in all company owned (COR) stores, business direct, telesales, and web sales. Under the COS Accessories SOW, Sprint transfers to Brightstar all collected accessory sale proceeds and, in return, Sprint generally receives from Brightstar a guaranteed amount of accessory product revenue for each device activation. The arrangement was approved by the Audit Committee on May 24, 2017. For fiscal year 2017, Sprint recognized approximately $154 million in revenues under this arrangement, and transferred to Brightstar approximately $142 million in collected accessory sale proceeds.

We have entered into ordinary course transactions between Sprint and Brightstar whereby Sprint agreed to (1) sell certain speaker accessories, and (2) purchase a retail content transfer software solution from Brightstar. Sprint incurred expenses of approximately $0.37 million and received payments of approximately $2.1 million pursuant to these arrangements during fiscal year 2017. The $2.1 million in payments were received as a result of Brightstar purchases as part of auctions which included a number of unrelated bidders. We have determined that our procedures were not followed in connection with these auction purchases because the purchases were not properly submitted in advance to the related party transaction committee or the Audit Committee for examination and approval. When the purchases were identified by management to be related party transactions, the purchases were promptly reported to the Audit Committee.

Effective November 21, 2014, Sprint and Brightstar entered into a Sublease Agreement whereby Brightstar leases approximately 7,500 square feet at Sprint’s campus in Overland Park, Kansas. Sprint is expected to receive approximately $332,550 in base rent during the remaining term ending March 31, 2020. Brightstar will also pay for certain operating costs and property taxes. In fiscal year 2017, Sprint received approximately $204,000 under the Sublease Agreement.

In fiscal year 2015, Sprint hired a former Brightstar employee who agreed to forgo his Brightstar severance package if Sprint paid him a signing bonus of $450,000. Brightstar agreed to reimburse Sprint for its $450,000 bonus cost. Accordingly, Sprint previously incurred expenses payable to such officer of approximately $450,000 pursuant to the transaction. In fiscal year 2017, we received the $450,000 reimbursement from Brightstar.

Proposal 2—Ratification of the Selection of the Independent Registered Public Accounting Firm

Proposal 2. Ratification of the Selection of the Independent Registered Public Accounting Firm

(Item 2 on Proxy Card)

Our Audit Committee has voted to appoint Deloitte & Touche LLP (Deloitte) as our independent registered public accounting firm to audit the consolidated financial statements and the effectiveness of internal control over financial reporting for our Company and our subsidiaries for the fiscal year ending March 31, 2019. Our stockholders are asked to ratify that appointment at the annual meeting. In keeping with good corporate governance, the Audit Committee will periodically assess the suitability of our incumbent independent registered public accounting firm taking into account all relevant facts and circumstances, including the possible consideration of the qualifications of other accounting firms.

Deloitte has served as the independent registered accounting firm of Sprint Corporation (formerly known as Starburst II, Inc.) since its formation in 2012.

Representatives of Deloitte are expected to be present at the annual meeting and will have the opportunity to make a statement and to respond to appropriate questions. If the appointment of Deloitte is not ratified at the meeting, the Audit Committee will consider the selection of another accounting firm.

The Audit Committee has adopted policies and procedures concerning our independent registered public accounting firm, including thepre-approval of services to be provided. Our Audit Committeepre-approved all of the services described above. The Audit Committee is responsible for thepre-approval of all audit, audit-related, tax andnon-audit services; however,pre-approval authority may be delegated to one or more members of the Audit Committee. The details of any services approved under this delegation must be reported to the full Audit Committee at its next regular meeting. Our independent registered public accounting firm is generally prohibited from providing certainnon-audit services under our policy, which is more restrictive than the SEC rules related tonon-audit services. Any permissiblenon-audit service engagement must be specifically approved in advance by the Audit Committee. We provide quarterly reporting to the Audit Committee regarding all audit, audit-related, tax andnon-audit services provided by our independent registered public accounting firm.

Our Board of Directors recommends that you vote “FOR” Proposal 2.

Principal Accounting Fees and Services

The Audit Committee has appointed Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending March 31, 2019. As described above, stockholders are being asked to ratify the appointment of Deloitte at the annual meeting pursuant to Proposal No. 2. Representatives of Deloitte are expected to be present at the annual meeting, will have the opportunity to make a statement if they desire to do so, and are expected to be available to respond to appropriate questions.

The following table provides the fees billed for professional services rendered by Deloitte for fiscal years 2016 and 2017. The Audit Committee determined that thenon-audit services rendered by Deloitte were compatible with maintaining its independence as our auditors.

The most significant engagement giving rise to thenon-audit related services is in connection with an FCC order (the FCC Order) for which a Deloitte affiliate serves as a subcontractor of the FCC. This FCC Order provides for an independent Transition Administrator (TA) to oversee the band reconfiguration process on behalf of the FCC. In 2009, Deloitte Consulting LLP, one of Deloitte’s affiliates (Deloitte Consulting), entered into a subcontractor agreement with the TA to provide certain services to the TA on behalf of the FCC and not Sprint. Sprint is obligated to fund implementation of the FCC Order and, therefore, pays the fees of the TA and Deloitte Consulting. Accordingly, the Audit Committee did not engage the Deloitte affiliate or otherwise approve those services. The interaction between Deloitte Consulting and Sprint under the subcontractor agreement is limited to routine interactions of exchanging factual information relevant to Deloitte Consulting’s or Sprint’s obligations under the FCC Order. Deloitte Consulting has no obligation to provide services to or for Sprint. In addition, the FCC is the only entity that can compel any obligation. Sprint does not supervise, direct, manage, or otherwise have any responsibility or accountability for Deloitte Consulting’s products or services under the subcontractor agreement with the TA, other than to pay the costs associated with the FCC Order. Given the nature of this relationship with Deloitte and Deloitte Consulting, the Audit Committee concluded that payments made pursuant to the FCC Order do not affect the independence of Deloitte with respect to its audits.

	Fiscal Year ended March 31, 2018	Fiscal Year  ended March 31, 2017
Audit Fees(1)	$11.5 million	$12.3 million
Audit-Related Fees(2)	$0.6 million	$0.4 million
Tax Fees	$0.2 million	$0.1 million
All Other Fees(3)	$6.2 million	$10.5 million

(1) For professional services rendered for the audit of our consolidated financial statements, the audit of the effectiveness of internal control over financial reporting, the review of the consolidated financial statements, and the audits of certain subsidiaries for statutory reporting purposes.

(2) For professional audit-related services rendered to us, generally related to other attestation services.

(3) Represents amounts paid by Sprint directly to Deloitte Consulting for work performed on behalf of the FCC pursuant to the FCC Order during fiscal years 2016 and 2017. No othernon-audit fees were paid to Deloitte.

Proposal 3 – Advisory Approval of the Company’s Named Executive Officer Compensation

Proposal 3. Advisory Approval of the Company’s Named Executive Officer Compensation

(Item 3 on Proxy Card)

The Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Exchange Act require that we permit our stockholders to vote to approve, on an advisory(non-binding) basis, the compensation of our named executive officers as disclosed in “Executive Compensation—Compensation Discussion and Analysis” and the accompanying executive compensation tables and related narrative and footnote disclosures. At our 2017 annual meeting of stockholders, our stockholders approved, on an advisory basis, that an advisory vote to approve named executive officer compensation should be held annually. Based on such result, our board determined that the advisory vote to approve named executive officer compensation would be held every year until the next advisory vote on the frequency of future advisory votes to approve named executive officer compensation, which will take place no later than our 2023 annual meeting of stockholders. Our board has recommended that the advisory votes to approve named executive officer compensation occur every year. Thus, it is anticipated that the next such advisory vote will occur at our 2019 annual meeting of stockholders.

Our executive compensation programs are designed to attract, motivate, and retain our named executive officers, who can contribute to our success. We believe our incentive compensation must strike a balance between rewarding achievement of our short-term objectives and rewarding long-term stockholder return and must be highly sensitive to the degree to which those results are realized. Please read “Executive Compensation—Compensation Discussion and Analysis” for additional details about our executive compensation programs.

We are asking our stockholders to indicate their support for our named executive officer compensation as described in this proxy statement. This proposal, commonly known as a“say-on-pay” proposal, gives our stockholders the opportunity to express their views on our named executive officers’ compensation. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement.

Our board recommends a voteFOR the approval of the compensation of our named executive officers, including as described in the Compensation Discussion and Analysis, the compensation tables and narrative discussion following such compensation tables, and the other related disclosures in this proxy statement.

Accordingly, we ask our stockholders to voteFOR the following resolution:

“RESOLVED, that the compensation paid to Sprint Corporation’s named executive officers, as disclosed pursuant to Item 402 of RegulationS-K, including the Compensation Discussion and Analysis, compensation tables and related narrative discussion, is hereby APPROVED.”

Thesay-on-pay vote is advisory, and therefore not binding on Sprint, the Compensation Committee, or our board of directors. Our board of directors and our Compensation Committee value the opinions of our stockholders and expect to take into account the outcome of the vote when considering future named executive officer compensation decisions to the extent they can determine the cause or causes of any significant negative voting results.

Our Board of Directors recommends that you vote “FOR” Proposal 3.

Address of Principal Executive Offices: 6200 Sprint Parkway, Overland Park, Kansas 66251.

Solicitation: These proxy materials are delivered in connection with the solicitation by our board of directors of proxies to be voted at our annual meeting of stockholders.

Purpose of the Annual Meeting

At the virtual annual meeting, you will be asked to:

_• elect each of the ten directors named herein (Item 1 on the proxy card);

_• ratify the selection of the independent registered public accounting firm (Item 2 on the proxy card);

_• approve, on an advisory basis, our named executive officer compensation (Item 3 on the proxy card); and

_• take action on any other business that properly comes before the meeting as well as adjournment or postponement of the meeting.

Record Date; Stockholders Entitled to Vote

The close of business on June 8, 2018 has been fixed as the record date for the determination of stockholders entitled to notice of, and to vote at, the 2018 annual meeting or any adjournments or postponements of the 2018 annual meeting.

As of the record date, we had 4,012,307,479 shares of our common stock outstanding of which 82,807 are not entitled to vote. These shares represent shares originally issued by Sprint Nextel that have not been exchanged for Sprint Corporation shares. Each share of our common stock entitles the record holder to one vote on each matter presented at the 2018 annual meeting.

A complete list of stockholders entitled to vote at the 2018 annual meeting will be available for examination by any stockholder at our Principal Executive Offices for purposes pertaining to the 2018 annual meeting during normal business hours for a period of ten days before the annual meeting and atwww.virtualshareholdermeeting.com/SprintCorp18 during the annual meeting.

“Street Name” and BrokerNon-Votes

You are a “record holder” if you hold our shares directly in your name through our transfer agent, Computershare Trust Company, N.A., as a stockholder of record. If you hold our shares through a broker, bank, financial institution, trust, or other nominee, then you are a holder of our shares in “street name.” If you hold your shares in “street name,” you must instruct the broker or other nominee about how to vote your shares.

A broker“non-vote” occurs when a stockholder holding in “street name” fails to provide voting instructions to his or her broker or other nominee. Under NYSE rules, if you do not provide such instructions, the firm that holds your shares will have discretionary authority to vote your shares with respect to “routine” matters. Of the three items to be considered at our annual meeting, only the appointment of Deloitte (Item 2) is considered “routine.” Thosenon-routine items for which a stockholder’s broker or other nominee does not have discretion to vote are treated as broker“non-votes.”

General Information

We request that you vote as soon as possible. When the proxy is properly submitted, the shares of stock represented by the proxy will be voted at the 2018 annual meeting in accordance with the instructions contained in the proxy.

If your shares are held in “street name” by a broker or other nominee, you should review the voting form used by that firm to determine whether you may provide voting instructions to the broker or other nominee by telephone or the Internet.

The deadline for voting by phone or via the Internet, except with respect to shares acquired through participation in our 401(k) plan, is 11:59 p.m. Eastern on August 6, 2018.

Revocability of Proxies and Changes to a Stockholder’s Vote

You have the power to revoke your proxy or change your vote at any time before the proxy is voted at the annual meeting. You can revoke your proxy or change your vote in one of four ways:

_• by sending a signed notice of revocation to our corporate secretary to revoke your proxy;

_• by sending to our corporate secretary a completed proxy card bearing a later date than your original proxy indicating the change in your vote;

_• by logging on towww.proxyvote.com in the same manner you would to submit your proxy electronically or calling1-800-690-6903, and, in each case, following the instructions to revoke or change your vote; or

_• by attending the annual meeting online and voting, which will automatically cancel any proxy previously given. Attendance alone will not revoke any proxy that you have given previously.

If you choose any of the first three methods, you must take the described action no later than the beginning of the 2018 annual meeting. Once voting on a particular matter is completed at the annual meeting, you will not be able to revoke your proxy or change your vote.

Solicitation of Proxies

This solicitation is made on behalf of our board, and we will pay the cost and expenses of printing and mailing this proxy statement and soliciting and obtaining the proxies, including the cost of reimbursing brokers, banks, and other financial institutions for forwarding proxy materials to their customers.

74  |  Notice of Annual Meeting and Proxy Statement  

General Information

If you do not instruct the trustee how to vote your shares, the 401(k) plan provides for the trustee to vote those shares in the same proportion as the shares for which it receives instructions from all other participants. To allow sufficient time for the trustee to vote, your voting instructions must be received by the trustee by 11:59 p.m. Eastern on August 2, 2018.

Delivery of Proxy Materials to Households Where Two or More Stockholders Reside

SEC rules allow us to deliver multiple Notices in a single envelope or a single copy of an annual report and proxy statement to any household where two or more stockholders reside if we believe the stockholders are members of the same family. This rule benefits stockholders by reducing the volume of duplicate information they receive at their households. It also benefits us by reducing our printing and mailing costs and reducing the environmental impact associated with our annual meeting.

We mailed Notices in a single envelope, or a single set of proxy materials, as applicable, to each household this year unless the stockholders in these households provided instructions to the contrary in response to a notice previously mailed to them. However, for stockholders who previously requested a printed set of the proxy materials, we mailed each stockholder in a single household a separate proxy card or voting instruction form. If you prefer to receive your own copy of the proxy materials for this or future annual meetings and you are a record holder, you may request a duplicate set by writing to shareholder relations, 6200 Sprint Parkway, Mailstop KSOPHF0302-3B679, Overland Park, Kansas 66251, by email atshareholder.relations@sprint.com, or by calling913-794-1091, and we will promptly furnish such materials. If a broker or other nominee holds your shares, you may instruct your broker to send duplicate mailings by following the instructions on your voting instruction form or by contacting your broker.

If you share a household address with another stockholder, and you receive duplicate mailings of the proxy materials this year, you may request that your household receive a single set of proxy materials in the future. If you are a record holder, please contact Sprint shareholder relations using one of the contact methods described above. If a broker or other nominee holds your shares, you should follow the instructions on your voting instruction form or contact your broker.

If you hold some shares as a record holder or through our 401(k) plan, and other shares in the name of a broker or other nominee, we must send you proxy materials for each account. To avoid receiving duplicate sets of proxy materials, you may consolidate accounts or consent to electronic delivery as described in the following section.

Internet Availability of the Proxy Materials

We are able to distribute the annual report and proxy statement to stockholders in a fast and efficient manner via the Internet. This reduces the amount of paper delivered to a stockholder’s address, eliminates the cost of sending these documents by mail and reduces the environmental impact associated with our annual meeting. You may elect to view all future annual reports and proxy statements on the Internet instead of receiving them by mail. Alternatively, you may elect to receive all future annual reports and proxy statements by mail instead of viewing them via the Internet. To make an election, please log on towww.proxyvote.com and enter your control number.

If you have enrolled for electronic delivery, you will receive an email notice of stockholder meetings. The email will provide links to our annual report and our proxy statement. These documents are in PDF format so you will need Adobe Acrobat^® Reader to view these documents online, which you can download for free by visitingwww.adobe.com. The email will also provide a link to a voting web site and a control number to use to vote via the Internet.
