Welcome, everyone, and thank you for joining us today. I'm joined this afternoon -- this morning by our President and COO, Adam Kleinman; and our CFO, Brent Pearson. As you may have seen, we announced an important transaction in conjunction with earnings. Yesterday, we entered the private REIT business through our acquisition of the Investment Management agreement for Monomoy Properties REIT, a private real estate investment trust with a 108-property portfolio of diversified net leased industrial assets representing $348 million of real estate.
This transaction is exactly what we should be doing to further our strategic objectives and is supported by every Board member. For reference, we added a number of slides to our earnings presentation that are dedicated to the transaction. At a high level, we believe this acquisition represents a transformative transaction for our investment management business and demonstrates significant progress towards our strategy of managing a diversified set of recurring fee generating long-duration capital vehicles. Our AUM more than doubled from $224 million to approximately $572 million.
From a financial perspective, GECM will earn an asset management fee equal to 1% of the REIT's NAV in addition to property management fees equal to 4% of gross rents. In the first quarter 2022, asset management fees for the Monomoy REIT were $0.4 million and pro forma for the transaction, property management fees would have been $0.3 million in the quarter.
Annualizing this quarterly result, this represents approximately $2.8 million in fees on an annualized basis. We believe the $10 million upfront purchase price is an attractive entry point at approximately 3.6x pro forma first quarter '22 annualized revenues on a growing durable capital vehicle.
Taking a step back, I'd like to outline our thesis by speaking to the transaction's 2 key pieces: acquiring the manager and investing into the REIT. Firstly, the manager acquisition adds another leg to our investment management stool and furthers our strategy of acquiring management rights to long-duration capital vehicles that utilize the expertise of our Board, management and GEG's financial resources, including its NOLs. Specifically, the acquisition is compelling, given the platform is backed by a skilled and seasoned management team. The underlying capital is sticky, and therefore, the management fees are durable. We believe there is a path to converting the REIT into a permanent capital vehicle and that GEG's unique tax structure provides it with a competitive advantage in raising additional capital for the Monomoy REIT. Moreover, the growth in fee revenue will allow GEG to leverage fixed overhead. And as outlined earlier, we believe at 3.6x pro forma annualized revenue, this is an attractive purchase price.
Secondly, we are making a strategic growth investment into the Monomoy REIT, which provides the GEG access to a diversified portfolio of industrial properties poised for sustainable growth. This investment follows our June 2021 investment of $4.6 million into the REIT, which has grown to $5.6 million as of March 31, 2022. The additional investment into the Monomoy REIT as part of this transaction is based on the strong track record of the management team, a large build-to-suit pipeline and GEG's tax attributes, which offer an advantage to shield both current income and long-term gains. Monomoy Properties is a private real estate investment trust with a 108-property portfolio across 27 states and 41 unique tenants.
The REIT holds a diversified portfolio of net leased industrial assets, representing $348 million of gross real estate at fair value as of March 31, 2022 and focuses on single tenant, light industrial properties with small building footprints on significant acreage. The trust targets investments in critical markets with favorable underlying economic trends and demographics, while building mutually beneficial relationships and streamlining the management of tenant's real estate.
The terms of the acquisition include multiple components. GEG has agreed to an upfront purchase price of $10 million at closing, financed with a combination of $2.5 million in newly issued shares of GEG stock, $1.25 million in shares of common stock of Great Elm Capital Corp., or GECC, that are owned by GEG; and three, a promissory note issued by GECM in an aggregate principal amount of approximately $6.3 million. In addition, there are 2 earn-out payments subject to meeting revenue growth targets of up to $1 million each following the fiscal years ending June 30, 2023, and June 30, 2024. Also, the transaction includes a targeted equity investment into the Monomoy REIT of up to $30 million to fund growth. GEG has committed to investing $15 million and intends to invest an additional $15 million over the next 12 months, although it is not contractually obligated to do so.
In summary, the Monomoy REIT's growth potential represents a substantial value creation opportunity for GEG. We are excited to partner with Chris Macri and his team to accelerate our investment management segment's growth.
From a capital perspective, yesterday, we filed a registration statement for a $30 million offering of senior unsecured notes. We expect to use the net proceeds of this offering to make investments in the Monomoy REIT and/or for general corporate purposes, including making opportunistic investments or refinancing subsidiary preferred stock or other indebtedness. Looking ahead, the offering likely serves as a template for future capital raises.
Turning to our results for the quarter ended March 31, 2022, we delivered another quarter of solid performance, highlighted by 20% growth in consolidated revenue on a year-over-year basis. Top line growth was broad-based across our DME and Investment Management segments with both businesses poised for growth, reflecting durable demand trends, sustainable competitive advantages and a transformational transaction.
Focusing on our Investment Management segment. Revenue for the quarter grew by 36% versus the prior year quarter, driven by rising AUM for GECC and our other investment vehicles. We remain focused on expanding and diversifying the platform by growing GECC through additional equity raises, debt issuances and opportunistic M&A as well as by adding additional clients and relationships through new fund launches and co-investment opportunities.
On the Durable Medical Equipment side, we again reported strong revenue growth despite ongoing macro headwinds, including persistent supply chain issues and limited medical device inventories.
Looking ahead, demand trends remain strong as evidenced by current backlog, which bodes well for the pace and sustainability of our growth. As is our standard practice, I wanted to reiterate the strong alignment between the Great Elm team and GEG shareholders. Employees and directors, including funds under their management, collectively own or manage approximately 30% of Great Elm's outstanding shares, and we continue to believe a meaningful disconnect exists between the underlying value of the Great Elm platform, particularly following the powerful acquisition of Monomoy properties and the current price of the stock.
With that, I'll turn it over to Brent to discuss our financial results for the quarter in more detail. Brent?
