Material Definitive Agreement regulatory

"Item 1.01. Entry into a Material Definitive Agreement."

A material definitive agreement is a legally binding contract that creates major, long‑term obligations or rights for a company, such as loans, asset sales, mergers, or supplier deals. Think of it like a mortgage or lease for a business: it can change future cash flow, risk and control, so investors watch these agreements closely because they can materially affect a company’s value, financial health and stock price.

Second Amended and Restated Credit Agreement financial

"seventeenth amendment (the “Amendment”) to the Second Amended and Restated Credit Agreement, dated as of November 1, 2013"

A second amended and restated credit agreement is a company’s loan contract that has been changed twice and rewritten into a single, updated document so all the terms are clear in one place. Investors care because it alters the company’s debt rules — such as interest rates, repayment schedule, and covenants — which affects cash flow, default risk, and the ability to invest or pay dividends; think of it like refinancing and reorganizing a mortgage that changes monthly payments and rules.

Administrative Agent financial

"Wells Fargo Bank, National Association, as administrative agent (the “Administrative Agent”)"

An administrative agent is a bank or financial firm appointed to handle the day-to-day paperwork and communication for a group of lenders on a loan or credit agreement, acting as the central point for collecting payments, distributing funds, monitoring covenants, and sharing information. For investors, the administrative agent matters because it influences how quickly lenders receive updates, how smoothly repayments and waivers are handled, and how effectively the lending group enforces terms — think of it as a property manager coordinating tasks for multiple owners.

total commitments financial

"increased the total commitments under the Credit Agreement from $2.5 billion to $3.0 billion"

Emerging growth company regulatory

"Emerging growth company o"

An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.
