Dear Dyal Capital Partners Investor:

I am writing to update you with more information regarding the merger of Owl Rock Capital Group (“Owl Rock”) and Dyal Capital Partners (“Dyal”). This letter is an update to the notice we sent you on December 2, 2020.

Owl Rock and Dyal are combining to form Blue Owl Capital (“Blue Owl”), a publicly-traded alternative asset management firm. This combination brings together two industry leaders and integrates Owl Rock’s direct lending platform for middle-market companies with Dyal’s capital solutions and strategic support for alternative asset managers. Blue Owl is expected to be listed on the NYSE through a combination with Altimar Acquisition Corporation, a special purpose acquisition company (“SPAC”).

We believe that the combination of Dyal and Owl Rock, two leading businesses in their respective fields, will create the preeminent provider of holistic solutions to the alternative asset management community. Both Dyal and Owl Rock will continue to be led by their current long-tenured management and investment teams, and they will continue to employ the disciplined investment philosophies they have pursued since inception. Upon close, Blue Owl is expected to be listed on the NYSE under the new ticker “OWL.”

Blue Owl will have over $45 billion in assets under management and a global footprint. Through the Dyal business, Blue Owl will be one of the leading providers of GP capital solutions to private market managers, with 100% permanent capital that enables the formation of long-term, stable partnerships with leading alternative asset managers.

We believe that you, as a Dyal investor, will benefit from the expanded platform and a strategic combination that has been structured to avoid any disruption to the service you receive, our investment program or our strong alignment with our stakeholders.



Dyal’s advantage in the GP stake sales and financing strategies will be further solidified by the creation of a platform that can help the broadest possible array of alternative asset managers address needs throughout their capital structures



The combined organization will have hundreds of distinct relationships across the alternative asset management universe, giving it vital access to investment opportunities



At Blue Owl, Dyal will have access to a broad array of lending solutions that can support the needs of Dyal partner managers; Owl Rock will have access to equity solutions for the sponsors to whom they lend. This complementary approach should deliver value for present and future Dyal partner managers and investors.





We also believe that the broader alternative asset management community, and the firms with whom Dyal and Owl Rock partner, will also benefit from this combination. Managers will now have access to a broader platform of services from a long-term partner who can better support their growth with a full suite of capital and strategic resources.

Blue Owl will prioritize the continuity of Owl Rock’s and Dyal’s respective investment and leadership teams. Owl Rock and Dyal have similar entrepreneurial and team-oriented cultures that will support one another as the two firms become one. Blue Owl will combine the two organizations’ industry-leading, aligned management teams with proven track records and long-term orientations.

I will continue to lead the Dyal business, which will operate autonomously within Blue Owl, and our investment team and processes will remain consistent. Doug Ostrover, co-founder and CEO of Owl Rock will serve as the CEO of Blue Owl, while Owl Rock President Marc Lipschultz and I will be Co-Presidents of the combined entity. Owl Rock CFO Alan Kirshenbaum will serve as CFO of the combined entity. Owl Rock’s founders and Dyal’s senior management will own meaningful positions in the combined business alongside Neuberger Berman.

We will be following up in the coming weeks with additional information about the strategic combination as well as an investor consent for the associated change of control. Please remember that the information in this letter is confidential in nature, and, as always, do not hesitate to reach out with questions.



Michael Rees

Head of Dyal Capital Partners
