Toronto, December 10, 2018 – Onex Corporation (“Onex”) (TSX: ONEX) and its affiliates
(the “Onex Group”) today announced they have agreed to sell BrightSpring Health Services
(“BrightSpring”), the leading provider of comprehensive home and community-based health
services to complex populations in need of specialized care. The transaction is expected to close
in the first quarter of 2019 subject to customary closing conditions, including regulatory approval.
The terms of the transaction are not being disclosed.

“Over the course of our ownership, BrightSpring has significantly increased the breadth and depth
of its services through a combination of organic growth, add-on acquisitions and improvements in
its service-delivery model – striving to be a leading partner to states and payors in its markets. In
the process, the company has built a full suite of clinical and non-clinical services, the delivery of
which make a difference in people’s lives and in the communities BrightSpring serves,” said Josh
Hausman, a Managing Director of Onex. “We’d like to thank Jon Rousseau, BrightSpring
management and all of the company’s service professionals for being great partners to Onex and
its investors. We’re extremely proud of the company’s mission to help people live their best life,
and we wish the team continued success in the future.”

“Onex has been a terrific partner. We’re grateful for its commitment and support, which has
allowed us to expand our reach and impact more lives, invest in technology and standards, and
provide quality and compassionate care where and when our clients and patients need it most,”
said Jon Rousseau, President and Chief Executive Officer of BrightSpring. “Onex’ commitment
to our employees, the people we serve, and quality and service has been unwavering, and it has set
the tone throughout our organization.”

In June 2004, Onex made an initial minority investment in BrightSpring (formerly ResCare)
through Onex Partners I and, in November 2010, invested additional capital through Onex
Partners III to acquire a majority stake in a take-private transaction. Onex’ portion of the sale
proceeds as a Limited Partner in the Funds is expected to be approximately $190 million, including
carried interest of $39 million. This results in a blended gross multiple of invested capital of
5.7 times. BrightSpring is the last investment in Onex Partners I. In total, this fund made ten
platform investments and generated a gross multiple of invested capital of 4.0 times (net multiple
of invested capital of 3.1 times) and an approximate 55% gross rate of return (net rate of return
of 38%).

Munich/London, December 3, 2018 – Nestor Primecare Services Limited, which is owned by the AURELIUS Group (ISIN DE000A0JK2A8), sold part of its homecare services business in England, Scotland and Wales to the Health Care Resourcing Group (CRG), Prescot, UK.

CRG is one of the biggest British staffing services providers in the healthcare and nursing sector in Great Britain. It will combine the acquired business with its own activities, creating one of the biggest British providers of homecare services. The homecare services business in Northern Ireland and Ireland is not affected by this sale and will remain with AURELIUS. The parties agreed to keep the purchase price secret.

AURELIUS acquired the business operated under the brand names “Allied Primecare” and “Allied Healthcare” from Saga plc. in late 2015 and has restructured it extensively since that time.

Ingerø Reiten Investment Company AS (“IRIC”) has today acquired 2.916.667 shares in Navamedic ASA, representing an ownership of 26.84% in the company. IRIC and related parties did not own any shares in Navamedic ASA prior to this transaction, and following the transaction holds 2.916.667 shares in total.

Nordstjernan’s subsidiary Lideta, which also includes the Mama Mia health care group, has signed an agreement to acquire the Primary Health Care business area from Aleris. The acquisition covers a total of eleven health care centers in the Stockholm region and Uppsala, with 107,000 listed patients. The company has 275 full-time employees, and sales for 2018 were estimated at SEK 325 million. The acquisition is conditional upon approval from the relevant competition authorities. After the acquisition, Lideta will have 247,000 listed patients and approximately 775 employees, and it is estimated that sales will increase around 40 percent to just over SEK 1 billion. Lideta will thus become Sweden’s third largest private operator in primary health care.

In 2017, Nordstjernan acquired the health care companies Lideta and Mama Mia with the intent of developing a high-quality operator in Swedish health and medical care, with a focus on primary health care. The acquisition of Aleris’s Primary Health Care business area is part of its focus on primary health care.

“Nordstjernan believes that private health and medical care will play a central role in meeting patients’ growing needs for accessibility and quality. We believe that much of this future expansion will take place in the important field of primary health care. With Lideta’s acquisition of health care centers from Aleris, we will continue to expand in the welfare sector as a long-term owner,” said Nordstjernan’s President and CEO Tomas Billing.
