forward-looking statements regulatory

"Certain statements included in this communication are forward-looking statements within the meaning of Section 27A"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

definitive merger agreement regulatory

"the parties’ ability to consummate the proposed merger pursuant to the terms of the definitive merger agreement"

A definitive merger agreement is the final, signed contract that sets the exact terms for two companies to combine, including the price, payment method, conditions to closing, and what happens if the deal falls apart. For investors it matters because it turns a tentative plan into a legally binding arrangement—like signing a mortgage rather than agreeing to look at a house—so it often has an immediate effect on share prices and clarifies the risks from regulatory approval, financing or breakup fees.

registration statement on Form S-4 regulatory

"please see American Water’s registration statement on Form S-4 (Registration No. 333-292182)"

A registration statement on Form S-4 is a formal filing with the U.S. Securities and Exchange Commission used when a company issues shares or other securities as part of a merger, acquisition, exchange offer or similar corporate deal. It bundles the transaction terms, financial statements, risk factors and shareholder vote materials so investors can assess the deal; think of it as a detailed prospectus or buyer’s packet that explains what you would own and how the deal could change your stake.

joint proxy statement/prospectus regulatory

"included in American Water’s and Essential Utilities’ respective annual and quarterly reports and in the definitive joint proxy statement/prospectus"

A joint proxy statement/prospectus is a single, combined document that both asks shareholders to vote on a proposed transaction and provides the detailed information required when new securities are being offered. Think of it as a combined ballot and product brochure that explains the deal, the companies’ finances, key risks and how ownership will change. Investors rely on it to understand the terms, evaluate risks and make informed voting and investment decisions.

regulatory lag financial

"filings to address regulatory lag; the combined company’s ability to execute its current and long-term business"

Regulatory lag is the delay between when government or oversight bodies create, change, or enforce rules and when those rules actually take effect or when firms receive required approvals. For investors it matters because those delays can postpone revenue, increase costs, or extend uncertainty around a project or business plan — like sitting at a traffic light that won’t change, you can’t move forward or adjust your timing until the signal does.
