Great-West Lifeco Inc. (Great West or the Company) subsidiary Empower today announced that it has entered into a definitive agreement with Milliman, Inc. (Milliman) to acquire Milliman's retirement plan and benefits administration business. Subject to regulatory approvals and other customary closing conditions, Empower will acquire the business for total consideration of US$340 million.

Supported by a strong technology platform and deep domain expertise, the acquired business provides defined contribution (DC), defined benefit (DB), and health & welfare (H&W) administration services to corporate, public sector, trade labor union, multi-employer, and non-profit clients, with approximately US$130 billion in client assets across 1.5 million participants. The transaction represents a significant step forward in Empower's strategy to deliver an integrated workplace ecosystem, enhancing its ability to serve clients with broader and more comprehensive retirement and benefits solutions.

"The acquisition reflects our disciplined approach to capital deployment and our focus on strengthening high-quality, capital-efficient growth platforms," said David Harney, President and CEO, Great West. "It also aligns with our strategy of pursuing opportunities that add scale, expand and deepen capabilities, and generate attractive long-term returns, while leveraging the strong execution discipline and financial flexibility we have built across the organization."

Edmund F. Murphy III, CEO, Empower added, "This transaction significantly strengthens our ability to compete and win across the full spectrum of retirement solutions by bringing a leading defined benefit platform in-house. The business' strong reputation, high-quality client base, and scalable platform align closely with our long-term strategy. Together, we will unlock meaningful value through innovation, improved client outcomes, and expanded growth opportunities across defined contribution, defined benefits, and benefits administration."

Strategic Rationale

The transaction advances Empower's strategy by expanding its workplace solutions platform and enhancing its competitive positioning.

Cautionary note regarding Forward-Looking Information

From time to time, Great West makes written and/or oral forward-looking statements within the meaning of applicable securities laws, including in this release. Forward-looking information includes statements that are predictive in nature, depend upon or refer to future events or conditions, or include words such as "achieve", "ambition", "anticipate", "believe", "could", "estimate", "expect", "initiatives", "intend", "may", "objective", "opportunity", "plan", "potential", "project", "target", "will" and other similar expressions or negative versions of those words. These include, without limitation, statements about:  (a) the timing and completion of the proposed acquisition of Milliman's retirement plan and benefits administration business; (b) the expected costs and benefits of the proposed acquisition, including statements about the timing and cost of integration activities, the timing and extent of expected cost efficiencies and synergies, increased scale, capabilities and marketing of Empower, revenue diversification, value creation/realization and growth opportunities, product and service innovation, and improved client outcomes; (c) the impacts of the proposed acquisition on Great West's and Empower's financial condition and flexibility, including statements about the expected internal rate of return of the proposed acquisition and expected base earnings accretion resulting from the proposed acquisition; and (d) other statements about the businesses and financial condition of Great West (including expected share repurchases), Empower and the acquired business and the U.S. retirement and benefits industry generally.

Forward-looking statements are based on expectations, forecasts, estimates, predictions, projections and conclusions about future events that were current at the time of the statements and are inherently subject to, among other things, risks, uncertainties and assumptions about the Company, economic factors and the financial services industry generally, including the U.S. retirement and benefits industry. This information has been provided to the reader to give an indication of Great West's current expectations concerning the impact of the proposed acquisition and these statements may not be suitable for other purposes. They are not guarantees of future performance, and actual events and results could differ materially from those expressed or implied by forward-looking statements.

In particular, in calculating the expected IRR and accretive nature of the proposed acquisition, management has estimated retention of client assets, expense synergies, foregone earnings on surplus used to finance the acquisition and integration expenses. With respect to Great West's expected level of share repurchases, the amount and timing of actual repurchases will depend on the earnings, cash requirements and financial condition of Great West, market conditions, our ability to effect the repurchases on a prudent basis, capital requirements, applicable law and regulations (including applicable securities laws), and other factors deemed relevant by Great West, and may be subject to regulatory approval or conditions. Many of these assumptions are based on factors and events that are not within the control of the Company and there is no assurance that they will prove to be correct.

In all cases, whether or not actual results differ from forward-looking information may depend on numerous factors, developments and assumptions, including, without limitation, the achievement of waiver of closing conditions to the proposed acquisition, the ability to integrate and leverage the proposed acquisition and achieve anticipated benefits and synergies, the achievement of expense synergies and client retention targets from the proposed acquisition assumptions around sales, pricing, fee rates, customer behaviour (including contributions, redemptions, withdrawals and lapse rates), global equity and capital markets (including continued access to equity and debt markets and credit instruments on economically feasible terms), geopolitical tensions and related economic impacts, interest and foreign exchange rates, inflation levels, liquidity requirements, investment values and asset breakdowns, hedging activities, financial condition of industry sectors and individual issuers that comprise part of the Company's investment portfolio, credit ratings, taxes, impairments of goodwill and other intangible assets, technological changes, including use of emerging technologies, such as artificial intelligence (AI), in our business, breaches or failure of information systems and security (including cyber attacks), assumptions around third-party suppliers, changes in local and international laws and regulations, changes in accounting policies and the effect of applying future accounting policy changes, changes in actuarial standards, unexpected judicial or regulatory proceedings, catastrophic events, continuity and availability of personnel and third-party service providers, unplanned changes to the Company's facilities, customer and employee relations, levels of administrative and operational efficiencies, and other general economic, political and market factors in North America and internationally.

The above list is not exhaustive, and there may be other factors listed in the Company's filings with securities regulators, including those set out in the "Risk Management" and "Summary of Critical Accounting Estimates" sections of the Company's 2025 Annual MD&A and in the Company's annual information form dated February 11, 2026 under "Risk Factors". These, along with other filings, are available for review at www.sedarplus.ca. The reader is cautioned to consider these and other factors, uncertainties and potential events carefully and not to place undue reliance on forward-looking information.

Other than as specifically required by applicable law, the Company does not intend to update any forward-looking information whether as a result of new information, future events or otherwise.
