Forward Looking Statements

This Current Report on Form 8-K contains certain forward-looking statements with respect to the financial condition, results of operations and business of Centene, Health Net and the combined businesses of Centene and Health Net and certain plans and objectives of Centene and Health Net with respect thereto, including the expected benefits of the proposed merger. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often use words such as “anticipate”, “target”, “expect”, “estimate”, “intend”, “plan”, “goal”, “believe”, “hope”, “aim”, “continue”, “will”, “may”, “would”, “could” or “should” or other words of similar meaning or the negative thereof. There are several factors which could cause actual plans and results to differ materially from those expressed or implied in forward-looking statements. Such factors include, but are not limited to, the expected closing date of the transaction; the possibility that the expected synergies and value creation from the proposed merger will not be realized, or will not be realized within the expected time period; the risk that the businesses will not be integrated successfully; disruption from the merger making it more difficult to maintain business and operational relationships; the risk that unexpected costs will be incurred; changes in economic conditions, political conditions, changes in federal or state laws or regulations, including the Patient Protection and Affordable Care Act and the Health Care Education Affordability Reconciliation Act and any regulations enacted thereunder, provider and state contract changes, the outcome of pending legal or regulatory proceedings, reduction in provider payments by governmental payors, the expiration of Centene’s or Health Net’s Medicare or Medicaid managed care contracts by federal or state governments and tax matters; the possibility that the merger does not close, including, but not limited to, due to the failure to satisfy the closing conditions, including the receipt of approval of both Centene’s stockholders and Health Net’s stockholders; the risk that financing for the transaction may not be available on favorable terms; and risks and uncertainties discussed in the reports that Centene and Health Net have filed with the Securities and Exchange Commission (the “SEC”). These forward-looking statements reflect Centene’s and Health Net’s current views with respect to future events and are based on numerous assumptions and assessments made by Centene and Health Net in light of their experience and perception of historical trends, current conditions, business strategies, operating environments, future developments and other factors they believe appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. The factors described in the context of such forward-looking statements in this announcement could cause Centene’s and Health Net’s plans with respect to the proposed merger, actual results, performance or achievements, industry results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and persons reading this announcement are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as of the date of this announcement. Neither Centene nor Health Net assumes any obligation to update the information contained in this announcement (whether as a result of new information, future events or otherwise), except as required by applicable law. A further list and description of risks and uncertainties

FOR IMMEDIATE RELEASE

CENTENE TO COMBINE WITH HEALTH NET IN TRANSACTION VALUED AT APPROXIMATELY $6.8 BILLION

Creates Leading Platform for Government-Sponsored Programs and One of the Largest Medicaid Managed Care Organizations in the Country

Broadens Presence to Build Scale and Drive Diversification

Transaction Expected to be Significantly Accretive to Centene’s EPS in the First Year Following Close

Estimated to Achieve up to Approximately $150 Million in Annual Synergies by the Second Year Following Close

Companies to Host Conference Call at 8:30 AM ET

St. Louis, MO and Los Angeles, CA – July 2, 2015 – Centene Corporation (NYSE: CNC) and Health Net, Inc. (NYSE: HNT) announced that the Boards of Directors of both companies have unanimously approved a definitive agreement under which Centene will acquire all of the shares of Health Net in a cash and stock transaction valued at approximately $6.8 billion, including the assumption of approximately $500 million of debt.

The combination of Centene and Health Net would create a leading diversified multi-national healthcare enterprise with more than ten million members across the country and estimated 2015 pro forma premium and service revenues of approximately $37 billion. Centene is expected to continue to deliver attractive growth by offering a more comprehensive and scalable portfolio of innovative solutions focusing on uninsured and under-insured individuals, including participation in Medicare Advantage, TRICARE, and Veterans Affairs programs. The companies believe that the addition of Health Net’s high-quality Medicare platform to Centene’s Medicaid programs provides an opportunity for additional growth across the combined company’s markets. Health Net’s demonstrated commitment to risk-based provider arrangements is reflective of the market shift from volume to value and is anticipated to enhance Centene’s leading position in high quality, low cost access to government-sponsored programs. With increased scale and diversification, Centene expects to deploy its full portfolio of specialty services and provide an integrated offering that benefits its members, providers and other stakeholders.

Under the terms of the agreement, Health Net shareholders would receive 0.622 shares of Centene common stock and $28.25 in cash for each share of Health Net common stock. Based on Centene’s closing stock price on July 1, 2015, the implied consideration of $78.57 per share represents a premium of approximately 21% over Health Net’s closing stock price on July 1, 2015, and of approximately 26% on June 1, 2015. Upon completion of the transaction, Centene shareholders would own approximately 71% of the combined entity, with Health Net shareholders owning approximately 29%. The transaction is expected to be significantly accretive to Centene’s diluted earnings per share in the first year following closing.

“We are pleased to have reached this agreement with Health Net, which we believe will create value for both Centene and Health Net shareholders and will enhance our ability to serve our members and work with our providers and government partners,” said Michael F. Neidorff, Centene’s Chairman, President

and Chief Executive Officer. “Over the past five years, Centene has achieved record performance and today’s announcement is a significant next step in our strategy to increase scale and drive geographic and product diversification. This transaction ensures that we extend our competitive position as one of the largest plans covering government-sponsored programs in the country. Health Net’s presence in California and other key western states is complementary to our offerings, allowing us to bring additional innovative solutions to the healthcare market. With Health Net, we see opportunities to leverage our local approach more broadly to enhance our members’ access to higher quality healthcare services on a cost-effective basis and ensure measurable quality outcomes.”

Mr. Neidorff continued, “We have tremendous respect for Health Net’s management team and employees, and for all that they have accomplished. Given our scalable model and record of successfully integrating acquisitions, we expect to achieve a smooth transition. Together, we will build on both companies’ shared commitment to working with providers and key community stakeholders to achieve better results for members and drive shareholder value.”

Jay Gellert, Health Net’s President and Chief Executive Officer, said, “Centene has an impressive record of serving populations that have been traditionally underserved in a high-quality and consumer-centered manner. Our successes complement Centene very well and will lead to better offerings in line with new consumer and payer demands. After closing, we will be a leading provider of managed health care services very much aligned with the future. We expect that Health Net associates will play a critical role in the future of the combined company.”

Strategic and Financial Benefits of the Transaction

• Addition of Incremental Scale: The addition of Health Net’s complementary network is expected to strengthen Centene’s presence in the California Medicaid program, which is the country’s largest with more than 12 million individuals. The transaction will provide Centene with access to California’s dual demonstration program and expansion in other Medicaid and Medicare programs in the Western United States, including Arizona, Oregon and Washington. The combined company expects to have approximately six million Medicaid members, making it one of the largest Medicaid managed care organizations in the country. The combined company anticipates driving profitable growth by leveraging Centene’s local approach that provides members access to high quality and culturally sensitive health care services.

• Increased Product Diversity Provides Ability to Create a More Comprehensive Portfolio: This transaction would extend Centene’s offerings in government programs including Medicare, TRICARE, and U.S. Department of Veterans Affairs. The combined company would be positioned to provide its members access to more solutions, with opportunities for integrated specialty services across the entire enterprise. In particular, the combined company believes that Health Net’s high quality Medicare platform, including its presence in Medicare Advantage, has the potential to be applied across the combined business thereby enhancing the growth strategy. Centene also believes there are opportunities to scale Health Net’s programs that reach underserved communities and extend its business lines for this constituency. Both companies have demonstrated success focusing on the subsidized portion of the Health Insurance Marketplace. The companies believe that by focusing on these government programs, the combined company will enhance its innovative provider relationships that enable it to deliver affordable, accessible healthcare.

• Strong Financial Profile and Significant Earnings Accretion: Combined, Centene and Health Net are estimated to have 2015 pro forma annual premium and service revenues of approximately

$37 billion. The transaction is expected to generate diluted earnings per share accretion of 10% and adjusted diluted earnings per share accretion of 20% in the first year following closing.

• Significant Synergy Opportunities: The combined company is estimated to achieve approximately $150 million of annual cost synergies by the second year following close with 50% achieved after year one following close. Synergies will come from areas including efficiencies in core G&A, integration of a range of specialty services and leveraging capabilities in IT systems and process management.

Organization and Management

Upon closing of the transaction, Mr. Neidorff will lead the combined company as Chairman, President and Chief Executive Officer. Mr. Gellert will assist to achieve a smooth transition. The combined company will be headquartered in St. Louis, Mo, the location of Centene’s current headquarters, with operations throughout the country.

Financing and Approvals

Centene intends to fund the cash portion of the acquisition through a combination of existing cash on hand and debt financing. The transaction is not contingent upon financing, with Wells Fargo, N.A. providing $2.7 billion of financing commitment.

The transaction is expected to close by early 2016. It is subject to approval by Centene and Health Net shareholders, the expiration or termination of the applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, approvals by relevant state insurance and healthcare regulators and other customary closing conditions.

Associate Message and Key Talking Points

Subject/Headline: Health Net and Centene to Combine

A message from Jay Gellert, President and CEO, Health Net

This morning, Health Net and Centene jointly announced a definitive agreement under which Centene and Health Net will combine in a cash and stock transaction valued at approximately $6.8 billion, including the assumption of approximately $500 million in debt. The transaction is subject to regulatory review, our stockholders’ approval and other customary closing conditions. You can read the press release by clicking here.

Speaking for management and the board, I want all of you to know that Centene shares our deep appreciation for your skill, dedication and hard work and achievements. We have a compelling plan for the future that will be made even stronger through this transaction. At this time, we are limited in what we can communicate because our planning is still in progress. Additionally, we have yet to file our definitive proxy statement with the Securities and Exchange Commission and, due to the amount of regulatory approval typically required for a transaction of this type, do not expect to close for several months.

In our discussions, Centene has been impressed with our approaches to and success with the individual exchanges, Medicaid expansion and the duals demonstrations, among others. As we move forward with Centene, our capacity for further investment in these opportunities – and others sure to come – is markedly enhanced. Add to that our strong positions in California and in serving military personnel and their families, which will augment Centene’s leading positions in Medicaid across the country and we see that our future can be even stronger by our combination.

We have noted for some time that Health Net needed to address scale issues. It’s why we have pursued the BPaaS transaction with Cognizant. As a result of today’s announcement, we are placing the BPaaS-related work on pause.

The Board believes that our combination with Centene is the right step to take at this time, providing broader scope, scale and resources as we address the challenges of the rapidly changing health care landscape.

Between now and the closing of the transaction, we expect that there will be no material changes in how we operate day-to-day. We’ll remain focused on our new initiatives and continue to meet our commitments to our members, providers and other key stakeholders. They are all counting on us and I know you’ll continue to do the great work they’ve come to expect.

In the coming weeks and months, Centene and Health Net will create a comprehensive integration plan. Along the way, I’m certain you’ll also be hearing directly from Centene management as plans for the combined company crystalize.

In closing, let me again thank all of you for your steadfast dedication and hard work. Your efforts have brought us to this point – a point at which one of the leaders in our industry recognized the value in what we all accomplished together. We are very proud and you should be too.

Key Talking Points

• Today, Centene and Health Net jointly announced a definitive agreement under which Centene and Health Net will combine in a cash and stock transaction valued at approximately $6.8 billion, including the assumption of approximately $500 million in debt and valuing Health Net at approximately $78.57 per diluted share.

• The combination of Centene and Health Net would create a leading diversified health care services enterprise with more than 10 million members across the country and estimated 2015 pro forma premium and service revenues of approximately $37 billion.

• Health Net’s board of directors believes that the decision to combine with Centene is in the best interests of Health Net’s customers and its stockholders.

• For stockholders, it realizes substantial financial value that recognizes the potential contributions of Health Net’s new business opportunities. The consideration values Health Net at a substantial premium.

• For our commercial customers, it combines our expertise in tailored network products with Centene’s Medicaid presence across the country. We believe we can export our tailored network products to the exchanges in these states.

• In Medicare and Medicaid, it creates an organization that can build on our strengths in California, Medicare and the dual eligible beneficiaries and with Centene’s broad platform of diversified health solutions.

• There is very little overlap between the operations of the two companies.

• For our health care regulators, the combined organization will – with a strong commitment to regulatory compliance – be better equipped to address new health care laws while bringing greater scale and operational resources to the ACA Exchange membership, dual eligible beneficiaries, Medicaid expansion and other programs vital to health care’s future.

• For our provider partners, it brings the opportunity to partner with a strong and energized organization as we strive to meet the challenges of health care reform and other changes impacting the industry.

• For our associates, there could be many new opportunities as the combined organization will have the potential to take our success in many areas to a new level.

• Between now and the closing of the transaction, it’s business as usual – the vital work of serving our customers. All current terms and conditions of employment remain the same.

• The transaction is subject to the approval of our stockholders.

• The transaction is subject to regulatory approval and other customary closing conditions.

• More information about integration plans will be available in the weeks and months ahead.

Forward Looking Statements

This document contains certain forward-looking statements with respect to the financial condition, results of operations and business of Centene, Health Net and the combined businesses of Centene and Health Net and certain plans and objectives of Centene and Health Net with respect thereto, including the expected benefits of the proposed merger. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often use words such as “anticipate”, “target”, “expect”, “estimate”, “intend”, “plan”, “goal”, “believe”, “hope”, “aim”, “continue”, “will”, “may”, “would”, “could” or “should” or other words of similar meaning or the negative thereof. There are several factors which could cause actual plans and results to differ materially from those expressed or implied in forward-looking statements. Such factors include, but are not limited to, the expected closing date of the transaction; the possibility that the expected synergies and value creation from the proposed merger will not be realized, or will not be realized within the expected time period; the risk that the businesses will not be integrated successfully; disruption from the merger making it more difficult to maintain business and operational relationships; the risk that unexpected costs will be incurred; changes in economic conditions, political conditions, changes in federal or state laws or regulations, including the Patient Protection and Affordable Care Act and the Health Care Education Affordability Reconciliation Act and any regulations enacted thereunder, provider and state contract changes, the outcome of pending legal or regulatory proceedings, reduction in provider payments by governmental payors, the expiration of Centene’s or Health Net’s Medicare or Medicaid managed care contracts by federal or state governments and tax matters; the possibility that the merger does not close, including, but not limited to, due to the failure to satisfy the closing conditions, including the receipt of approval of both Centene’s stockholders and Health Net’s stockholders; the risk that financing for the transaction may not be available on favorable terms; and risks and uncertainties discussed in the reports that Centene and Health Net have filed with the Securities and Exchange Commission (the “SEC”). These forward-looking statements reflect Centene’s and Health Net’s current views with respect to future events and are based on numerous assumptions and assessments made by Centene and Health Net in light of their experience and perception of historical trends, current conditions, business strategies, operating environments, future developments and other factors they believe appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. The factors described in the context of such forward-looking statements in this announcement could cause Centene’s and Health Net’s plans with respect to the proposed merger, actual results, performance or achievements, industry results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and persons reading this announcement are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as of the date of this announcement. Neither Centene nor Health Net assumes any obligation to update the information contained in this announcement (whether as a result of new information, future events or otherwise), except as required by applicable law. A further list and description of risks and uncertainties can be found in Centene’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 and in its reports on Form 10-Q and Form 8-K as well as in Health Net’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 and in its reports on Form 10-Q and Form 8-K.

Message to BPaaS directly impacted associates

To:	BPaaS Tower Leads
Date:	July 2, 2015
Subject:	In Advance: Today’s Health Net/Centene Announcement – What It Means to You

The message below will be sent shortly to associates directly involved in the pending BPaaS agreement. We ask that you share with others who need this information.

To:	BPaaS impacted associates
From:	Juanell Hefner, BPaaS Transformation Officer
Date:	July 2, 2015
Subject:	Today’s Health Net/Centene Announcement – What It Means to You

As you’ve likely seen, this morning Health Net and Centene jointly announced a definitive agreement under which Centene and Health Net will combine. The transaction is subject to regulatory review, stockholders’ approval and other customary closing conditions. I encourage you to read the press release and other details on HN Connect.

This announcement has special implication for associates who’ve been preparing for Health Net’s pending expanded services agreement with Cognizant. With today’s announcement, the BPaaS agreement with Cognizant has been put on pause. Associates who accepted offer letters to rebadge to Cognizant or Teleperformance or have otherwise been involved with or affected by the BPaaS effort, will remain Health Net associates until such time as plans concerning today’s announcement crystalize. I therefore ask that you and your fellow teammates pause your BPaaS-related work until we have fuller details to share with you.

I know this is an abrupt change as we have been preparing intensely to implement the anticipated BPaaS arrangement. As Jay Gellert noted this morning, addressing scale issues is one of the reasons we have been pursuing the Cognizant transaction – and now our Board believes that our combination with Centene is the right step to take at this time. The combined organization will have the potential to take our success in many areas to a new level.

There will be a general all-associate call this afternoon to discuss highlights of today’s announcement; an invitation will be sent this morning. In the coming weeks, Centene and Health Net will create a comprehensive integration plan – and we will be providing specific information, as needed, to those who have been staging for the BPaaS transition.

Let me again thank you for your steadfast dedication and hard work. As we embrace this new challenge and opportunity, let’s remain focused on and continue to meet our commitments to our members, providers and other key stakeholders. They are all counting on us – and I know you’ll continue to do the great work they’ve come to expect.

Forward Looking Statements

This document contains certain forward-looking statements with respect to the financial condition, results of operations and business of Centene, Health Net and the combined businesses of Centene and Health Net and certain plans and objectives of Centene and Health Net with respect thereto, including the expected benefits of the proposed merger. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often use words such as “anticipate”, “target”, “expect”, “estimate”, “intend”, “plan”, “goal”, “believe”, “hope”, “aim”, “continue”, “will”, “may”, “would”, “could” or “should” or other words of similar meaning or the negative thereof. There are several factors which could cause actual plans and results to differ materially from those expressed or implied in forward-looking statements. Such factors include, but are not limited to, the expected closing date of the transaction; the possibility that the expected synergies and value creation from the proposed merger will not be realized, or will not be realized within the expected time period; the risk that the businesses will not be integrated successfully; disruption from the merger making it more difficult to maintain business and operational relationships; the risk that unexpected costs will be incurred; changes in economic conditions, political conditions, changes in federal or state laws or regulations, including the Patient Protection and Affordable Care Act and the Health Care Education Affordability Reconciliation Act and any regulations enacted thereunder, provider and state contract changes, the outcome of pending legal or regulatory proceedings, reduction in provider payments by governmental payors, the expiration of Centene’s or Health Net’s Medicare or Medicaid managed care contracts by federal or state governments and tax matters; the possibility that the merger does not close, including, but not limited to, due to the failure to satisfy the closing conditions, including the receipt of approval of both Centene’s stockholders and Health Net’s stockholders; the risk that financing for the transaction may not be available on favorable terms; and risks and uncertainties discussed in the reports that Centene and Health Net have filed with the Securities and Exchange Commission (the “SEC”). These forward-looking statements reflect Centene’s and Health Net’s current views with respect to future events and are based on numerous assumptions and assessments made by Centene and Health Net in light of their experience and perception of historical trends, current conditions, business strategies, operating environments, future developments and other factors they believe appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. The factors described in the context of such forward-looking statements in this announcement could cause Centene’s and Health Net’s plans with respect to the proposed merger, actual results, performance or achievements, industry results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and persons reading this announcement are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as of the date of this announcement. Neither Centene nor Health Net assumes any obligation to update the information contained in this announcement (whether as a result of new information, future events or otherwise), except as required by applicable law.

These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often use words such as “anticipate”, “target”, “expect”, “estimate”, “intend”, “plan”, “goal”, “believe”, “hope”, “aim”, “continue”, “will”, “may”, “would”, “could” or “should” or other words of similar meaning or the negative thereof. There are several factors which could cause actual plans and results to differ materially from those expressed or implied in forward-looking statements. Such factors include, but are not limited to, the expected closing date of the transaction; the possibility that the expected synergies and value creation from the proposed merger will not be realized, or will not be realized within the expected time period; the risk that the businesses will not be integrated successfully; disruption from the merger making it more difficult to maintain business and operational relationships; the risk that unexpected costs will be incurred; changes in economic conditions, political conditions, changes in federal or state laws or regulations, including the Patient Protection and Affordable Care Act and the Health Care Education Affordability Reconciliation Act and any regulations enacted thereunder, provider and state contract changes, the outcome of pending legal or regulatory proceedings, reduction in provider payments by governmental payors, the expiration of Centene’s or Health Net’s Medicare or Medicaid managed care contracts by federal or state governments and tax matters; the possibility that the merger does not close, including, but not limited to, due to the failure to satisfy the closing conditions, including the receipt of approval of both Centene’s stockholders and Health Net’s stockholders; the risk that financing for the transaction may not be available on favorable terms; and risks and uncertainties discussed in the reports that Centene and Health Net have filed with the Securities and Exchange Commission (the “SEC”). These forward-looking statements reflect Centene’s and Health Net’s current views with respect to future events and are based on numerous assumptions and assessments made by Centene and Health Net in light of their experience and perception of historical trends, current conditions, business strategies, operating environments, future developments and other factors they believe appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. The factors described in the context of such forward-looking statements in this announcement could cause Centene’s and Health Net’s plans with respect to the proposed merger, actual results, performance or achievements, industry results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and persons reading this announcement are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as of the date of this announcement. Neither Centene nor Health Net assumes any obligation to update the information contained in this announcement (whether as a result of new information, future events or otherwise), except as required by applicable law. A further list and description of risks and uncertainties can be found in Centene’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 and in its reports on Form 10-Q and Form 8-K as well as in Health Net’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 and in its reports on Form 10-Q and Form 8-K.

Exhibit 99.11

Patient-Centered Community Care Provider Communication

Health Net and Centene today announced that the two companies will combine to create a leading diversified health care services enterprise with more than ten million members across the country. The transaction is subject to regulatory review, stockholder approval and other customary closing conditions. Details are in our press release.

Our two organizations will immediately begin seeking all necessary regulatory approvals, and we expect it to close in early 2016.

Through all the upcoming activities, Health Net will continue being laser-focused on the needs of our customers and providers, who both have come to depend on us for quality, affordable health insurance coverage and service.

We are working hard to ensure that our customers and business partners experience a seamless transition of services, and Centene shares this commitment.

Our combined organization will be better equipped to address new business opportunities from the Affordable Care Act, bringing greater scale and operational resources to the commercial, Medicare, Cal MediConnect, and Medicaid expansion programs so vital to the success of our country’s health care future. And Health Net’s historical success with TRICARE and the U.S. Department of Veterans Affairs’ Patient-Centered Community Care and Veterans Choice programs provide incremental opportunities for Centene growth across the combined company’s markets.
