Purchase Agreement regulatory

"entered into a Purchase Agreement"

A purchase agreement is a legally binding contract that spells out exactly what is being bought, for how much, and under what conditions, including timelines, seller and buyer promises, and protections if things go wrong. For investors it matters because the agreement fixes the deal’s price, risks and closing conditions—like a detailed receipt and return policy for a large transaction—so it helps determine whether the deal will complete and how it will affect the company’s value and cash flow.

equityholders’ representative regulatory

"solely in its capacity as equityholders’ representative"

Put Option financial

"the Put Option, which was exercised on January 2, 2026"

A put option is a financial contract that gives its holder the right, but not the obligation, to sell a specified quantity of a stock or other asset at a set price within a defined time. Think of it like insurance on an investment—if the asset’s market price falls, the put lets an investor lock in a higher sale price or profit from the decline, helping limit losses or speculate on downward moves.

Cautionary Statement Regarding Forward-Looking Statements

This current report may contain “forward-looking statements” that involve risks and uncertainties. These statements can be identified by the fact that they do not relate strictly to historical or current facts, but rather are based on current expectations, estimates, assumptions and projections about the Company’s industry, business, strategy, technologies, acquisitions and strategic investments, market expansion plans, dividend policy, capital allocation, financing strategy, the put option associated with the remaining equity interests in MBI, which was exercised on January 2, 2026 (the “Put Option”), the purchase price payable pursuant to the Put Option (such purchase price, the “Put Price”), the anticipated timeline to consummate such transaction, the Company’s ability and sources of capital to fund the Put Price, MBI’s future indebtedness and the Company’s financial results and financial condition. Forward-looking statements often include words such as “will,” “should,” “anticipates,” “estimates,” “expects,” “projects,” “intends,” “plans,” “believes” and words and terms of similar substance in connection with discussions of future operating or financial performance. As with any projection or forecast, forward-looking statements are inherently susceptible to uncertainty and changes in circumstances. The Company’s actual results may vary materially from those expressed or implied in its forward-looking statements. Accordingly, undue reliance should not be placed on any forward-looking statement made by the Company or on its behalf. Important factors that could cause the Company’s actual results to differ materially from those in its forward-looking statements include government regulation, economic, strategic, political and social conditions and the following factors, which are discussed in the Company’s latest Annual Report on Form 10-K and in its subsequent filings with the Securities and Exchange Commission (the “SEC”), including its latest Quarterly Report on Form 10-Q:

	●	the integrity and security of the Company’s network and information systems;
	●	the impact of possible security breaches and other disruptions, including cyber-attacks;

	●	the possibility that interest rates will rise, causing the Company’s obligations to service its variable rate indebtedness to increase significantly;
	●	risks associated with the Company’s indebtedness, including the Company’s ability to pay dividends on, make distributions in respect of, repurchase or redeem, capital stock;
	●	provisions in the Company’s charter, by-laws and Delaware law that could discourage takeovers and limit the judicial forum for certain disputes;
	●	adverse economic conditions, labor shortages, supply chain disruptions, changes in rates of inflation and the level of move activity in the housing sector;
	●	pandemics, epidemics or disease outbreaks, such as the COVID-19 pandemic, have, and may in the future, disrupt the Company’s business and operations, which could materially affect the Company’s business, financial condition, results of operations and cash flows;
