How do you read a merger proxy?
A merger proxy is what a listed target sends shareholders before they vote on a sale, filed as a DEFM14A or inside a stock buyer's S-4. The preliminary version must reach the SEC at least 10 calendar days before the definitive one goes out (17 CFR 240.14a-6). Read the background, the fairness opinion and the projections first.
What is the difference between a DEFM14A and an S-4?
A DEFM14A is the definitive proxy statement for a merger; a PREM14A is the earlier preliminary draft, and PRER14A marks a revised preliminary (SEC EDGAR Filer Manual update, 2008). In an all-cash deal the target files a DEFM14A.
When the buyer pays with its own shares, it must register those shares, and it does so on Form S-4. The S-4 is the registration statement for securities issued in a business combination, and its Part I is a combined prospectus and proxy statement (Cornell LII, Form S-4). For research, both carry the same core sections. An S-4 adds the buyer's business, its risk factors and pro forma financials for the combined company.
Step 1. Find the right version on EDGAR
Search the target's name in SEC EDGAR and filter for PREM14A, DEFM14A, S-4 and S-4/A. Read the definitive version, because SEC comments often add detail to the preliminary one. Then open any later DEFA14A filings: supplements filed after a shareholder lawsuit often add projections or banker fees that the first version left out. Our guide to free SEC filing search tools shows faster ways to search.
Step 2. Read the background of the merger
The "Background of the Merger" section is a dated narrative of how the deal came together: who approached whom, how many parties signed confidentiality agreements, how many bid, how the price moved between rounds and when the board formed a special committee. It is the closest thing to a deal diary that a public company publishes.
Read it with 4 questions in mind. How many bidders were contacted and how many made offers? Did the price rise after a competing bid? Did management discuss its own roles or equity with the buyer before the price was agreed? Was a go-shop or market check run after signing? Parties are often named as "Party A" or "Party B"; cross-check them against later deal news.
Step 3. Read the fairness opinion summary
The fairness opinion is the financial adviser's letter saying the price is fair, from a financial point of view, to the shareholders. The proxy summarises the analyses behind it, and Item 1015 of Regulation M-A governs how reports, opinions and appraisals are described. SEC staff have said that requirement covers preliminary analyses shown to the board, not only the final one (SEC staff comment letter to Mediacom).
Look at 4 things. The valuation ranges from comparable companies, precedent transactions and a discounted cash flow, and where the offer price sits in each. The discount rate and terminal multiple used. The adviser's fee and how much of it depends on the deal closing. Any recent work the adviser did for the buyer, which the proxy discloses as a possible conflict. The full opinion letter is usually an annex at the back.
Step 4. Read the projections
Most merger proxies include the management projections given to the board and the bankers, typically revenue, EBITDA and free cash flow for several future years. These are often the only forward figures a private buyer ever saw from the company, and they rarely appear anywhere else.
Read the caveats around them. Filings commonly state that the projections were prepared for internal use and are subjective, as a 2017 DEFM14A from MVP REIT did (SEC EDGAR). Compare them with the guidance the company gave the market before the deal. If the board case is lower than public guidance, the banker's valuation will be lower too.
Step 5. Read interests of directors and officers
The section on interests of directors and executive officers shows what insiders receive: accelerated equity, change of control payments and any agreed roles with the buyer. Set this beside the background narrative. Large payouts are common. The question is whether insiders negotiated their own terms before the price was settled.

Frequently asked questions
What does DEFM14A stand for?
It is the EDGAR form type for a definitive proxy statement relating to a merger or acquisition. The preliminary version is filed as PREM14A, and the information statement versions, used when no vote is solicited, are PREM14C and DEFM14C (SEC EDGAR Filer Manual update).
Where are the projections in a merger proxy?
They usually sit in a section titled "Certain Unaudited Prospective Financial Information" or "Management Projections", close to the fairness opinion summary. In an S-4 they appear in the same place inside the proxy statement and prospectus.
How long after the preliminary proxy is the definitive proxy filed?
At least 10 calendar days, under Rule 14a-6(a), unless the SEC agrees to a shorter period for good cause (17 CFR 240.14a-6). If the SEC staff review the filing and comment, the gap is often several weeks.
