About American Stock Transfer & Trust Company

American Stock Transfer & Trust Company, LLC, commonly known as AST, was a major U.S. transfer agent and shareholder-services company that handled stock ownership records, dividend payments, corporate actions, proxy services, stock transfers, lost certificates, direct-registration accounts, tax reporting, and other services for public companies and their registered shareholders. The company built a major presence in Brooklyn, New York, and became one of the better-known names in U.S. transfer-agency administration.

An important current update is that American Stock Transfer & Trust Company, LLC is no longer the current operating name. The company was renamed Equiniti Trust Company, LLC, usually marketed simply as EQ. Current shareholder materials specifically describe EQ as the former American Stock Transfer & Trust Company, while companies that previously identified AST as their transfer agent now direct shareholders to Equiniti’s current AST Access platform.

EQ continues to provide transfer-agent, share-registration, corporate-action, dividend, tax-reporting, employee-equity, proxy, and shareholder-support services. The historic 6201 15th Avenue, Brooklyn, NY 11219 location remains associated with legacy AST transfer operations in many issuer records, but current EQ materials and issuer disclosures also use newer correspondence and operations addresses in New Jersey and Minnesota.

The primary current shareholder-services number associated with Equiniti, formerly AST, is 800-937-5449 for callers in the United States and Canada.

The former AST brand is now part of EQ, so new content should identify Equiniti Trust Company, LLC as the current legal and operating name rather than presenting American Stock Transfer & Trust Company as a separate current company.

The AST name continues to appear in older securities filings, issuer websites, transfer forms, and shareholder correspondence, which is why many investors still search for it.

Investor Relations

Not applicable in the same way as a standalone public issuer. EQ provides financial administration services to public companies and shareholders rather than maintaining a shareholder-relations function for AST customers.

American Stock Transfer & Trust Company Products & Services

Transfer Agent Services

EQ acts as the official transfer agent for numerous public companies, maintaining records of registered shareholders and processing changes in stock ownership. This work is central to the former AST business and includes updating ownership records, registrations, addresses, account status, and other official shareholder information.

Stock Ownership Transfers

Shareholders can use EQ to transfer registered shares between owners, trusts, estates, beneficiaries, or other account registrations. Transfers may require a completed ownership-transfer form, tax certification, supporting legal documents, and, in some cases, a Medallion Signature Guarantee.

Shareholder Recordkeeping

EQ maintains official registered-holder records on behalf of client companies. These records can include the shareholder’s name, address, taxpayer information, share balance, dividend instructions, registration type, and historical transaction information.

Direct Registration System

Shareholders may hold eligible shares electronically through the Direct Registration System instead of maintaining physical stock certificates. DRS allows registered investors to hold shares on an issuer’s books through the transfer agent while retaining the ability to move eligible shares to or from a brokerage account.

Shareholder Central

The EQ Shareholder Central platform provides online access to registered-shareholder accounts. Users can review eligible holdings, download certain tax documents, manage account information, and access transfer-agent forms through the AST Access system.

Lost Stock Certificate Assistance

EQ helps registered shareholders report lost, stolen, or destroyed certificates and complete the replacement process. Replacement can require an affidavit, surety bond, processing fees, identity verification, and company-specific documentation.

Address Changes

Registered shareholders can contact EQ to update the mailing address associated with a directly registered account. Investors whose shares are held through a broker generally need to update their information with that brokerage instead, because the broker rather than the individual investor is listed as the registered owner.

Dividend Payments

EQ can administer dividend payments on behalf of corporate clients, including checks and direct deposits for registered shareholders. Shareholders may also contact EQ about missing dividend payments, banking changes, or dividend-related account questions when EQ acts as the issuer’s paying agent.

Dividend Reinvestment Plans

For issuers that offer dividend reinvestment programs through EQ, shareholders may be able to reinvest eligible cash dividends into additional shares. Specific fees, minimum holdings, purchase schedules, and enrollment rules are determined by each company’s plan documents.

Direct Stock Purchase Plans

Some companies use EQ to administer direct stock purchase plans that allow eligible investors to purchase shares directly through a company-sponsored plan instead of making every purchase through a traditional brokerage account.

Stock Sale Services

Certain issuer-sponsored plans allow registered shareholders to instruct EQ to sell shares held in their plan account. Sales can be aggregated and executed through a broker according to plan terms, with applicable service and processing fees deducted from the proceeds.

Cost Basis Reporting

EQ maintains and reports cost-basis information for covered securities under applicable IRS rules. Current EQ materials explain that its covered-security cost-basis reporting generally applies to stock acquired on or after January 1, 2011, with later effective dates for certain other securities and investment plans.

Tax Forms

Shareholders may receive forms such as Form 1099-DIV and Form 1099-B when applicable. EQ’s Shareholder Central can provide access to certain recent tax documents, while shareholders can contact support if a form requires correction or replacement.

Form W-9 and W-8 Processing

EQ processes tax-certification forms for registered shareholders. U.S. holders may need a Form W-9, while eligible non-U.S. investors generally use the appropriate Form W-8 to document tax status and applicable withholding treatment.

Corporate Actions

EQ supports companies during mergers, acquisitions, tender offers, reorganizations, stock splits, exchanges, rights offerings, distributions, and other corporate actions. These transactions can require extensive shareholder communications, payment processing, recordkeeping, and reconciliation.

Proxy Services

EQ provides services connected with annual meetings, proxy distribution, voting, and shareholder communications. These services help issuers manage the logistical and administrative requirements surrounding corporate governance and shareholder participation.

Employee Equity Plans

Equiniti’s wider U.S. and global operations provide administration support for employee share plans, executive equity arrangements, and other employee-ownership programs. These services can include recordkeeping, transactions, reporting, vesting support, and participant communications.

Shareholder Correspondence

EQ receives and processes shareholder correspondence involving account consolidation, registration changes, ownership transfers, dividend questions, tax documentation, and certificate issues. Because different issuers may use different account-specific phone numbers, shareholders should check their statement or issuer Investor Relations page when possible.

American Stock Transfer & Trust Company Corporate Phone Numbers

Main Shareholder Services Number

800-937-5449 is the most broadly published current EQ Shareholder Services number. Registered shareholders can use it for general assistance with accounts, stock transfers, lost certificates, registration changes, tax forms, dividend questions, and similar transfer-agent matters.

International Shareholder Number

718-921-8124 is widely published for callers outside the United States and Canada. It can also be used when a shareholder cannot access a toll-free U.S. number from an international location.

Hearing-Impaired TDD Number

866-703-9077 is published as a TDD line for hearing-impaired shareholders. An international TDD contact, 718-921-8386, is also listed in current issuer shareholder-service information.

Shareholder Portal Support

For access to Shareholder Central, use the issuer-specific support number shown on your statement when available, or begin with 800-937-5449. EQ’s support representatives can help determine whether an account is eligible for online access and what identifying information is needed.

Stock Transfer Support

800-937-5449 can be used for ownership-transfer questions. Before sending certificates or original legal documents, shareholders should confirm the current required mailing address and documentation because EQ has updated several processing addresses since the older AST era.

Lost Certificate Support

Registered shareholders who have lost a paper certificate can call 800-937-5449 for instructions. The replacement process can differ depending on the issuer, value of the shares, account registration, and whether a surety bond is required.

Tax Form Support

800-937-5449 can be used for questions involving shareholder tax documents. EQ also publishes HelpAST@equiniti.com for certain tax-document and shareholder-account requests.

General Shareholder Email

HelpAST@equiniti.com remains widely used for EQ’s legacy AST shareholder-service operation. Include the company name associated with your shares and enough account-identifying information for the representative to locate the correct relationship, but do not email passwords or full sensitive credentials.

Client-Specific Phone Numbers

EQ frequently assigns separate toll-free numbers to individual corporate issuers. For example, some companies publish specialized EQ numbers rather than the general 800-937-5449 line, so shareholders should prioritize the contact shown on their statement or the issuer’s official Investor Relations page.

Corporate Sales Number

EQ does not use the shareholder call center as its corporate-sales department. Companies interested in transfer-agent, corporate-action, proxy, or employee-plan services should use the commercial contact forms available through the EQ website.

Investor Relations Number

Not applicable for AST shareholder customers. If your question concerns a company whose shares EQ administers, contact that company’s Investor Relations department for business, earnings, governance, or investment questions and use EQ only for registered-shareholder account administration.

How to Reach a Real Person at American Stock Transfer & Trust Company

The best current route is to contact Equiniti Trust Company, LLC, because AST has been renamed EQ. Call 800-937-5449 from the United States or Canada, or 718-921-8124 from outside the country. Current shareholder materials commonly list call-center service from 8:00 AM to 8:00 PM Eastern Time on business days. Have the company name, shareholder registration, account number if available, mailing address, and a clear description of the request ready.

If your shares are held in a brokerage account rather than directly registered in your own name, EQ may not be able to change your personal brokerage records. In that situation, contact the broker first. For registered shares, ask EQ for a case or reference number when the issue requires follow-up, especially for lost certificates, estate transfers, ownership changes, tax corrections, or missing payments.

How to File a Complaint Against American Stock Transfer & Trust Company

Shareholders may need to complain about a delayed stock transfer, missing dividend, lost certificate process, incorrect registration, tax form, cost basis, estate transfer, account access, or another transfer-agent issue. Before escalating, collect your shareholder statement, company name, account number, correspondence, transfer documents, tracking numbers, tax forms, and dates of previous calls.

Step 1: Contact EQ Shareholder Services

Call 800-937-5449 and explain the issue to a shareholder-service representative. Identify the company whose securities are involved, the registered account name, and the type of request. Ask the representative to check the current account record and explain what documentation is missing or what processing stage the request has reached. Record the representative’s name, date, and any case number provided.

Step 2: Use the Shareholder Support Email

If documents or written detail are needed, email HelpAST@equiniti.com. Keep the subject specific and mention the issuer name and general account issue. Do not email passwords, online authentication codes, or full sensitive identity information unless EQ has provided a secure method for submitting it. Retain a copy of the email and any automated acknowledgment.

Step 3: Confirm That You Are a Registered Shareholder

Before escalating further, determine whether your shares are registered directly with EQ or held in street name through a broker. Transfer agents generally maintain records only for registered shareholders, while brokerage firms control the records of beneficial owners. If the broker is the registered holder, the broker may need to initiate the correction or transfer on your behalf.

Step 4: Resubmit Missing Transfer Documentation

For ownership transfers, estate transfers, trust registrations, or certificate transactions, ask EQ to identify every missing item before resubmitting the package. Depending on the transaction, required items can include a transfer form, stock certificate, tax certification, court documentation, trust papers, death certificate, signature guarantee, or other evidence. Send originals only when specifically required and use trackable delivery.

Step 5: Request Supervisor Review

If the problem remains unresolved after the normal processing period, call Shareholder Services again and request additional review or escalation. Provide the earlier case number, delivery tracking, date the documents were received, and copies of prior correspondence. Explain the specific outcome you are requesting, such as account correction, reissuance, replacement payment, transfer completion, or tax-form amendment.

Step 6: Send Formal Written Correspondence

For a serious unresolved complaint, send written correspondence to the current EQ Shareowner Services address shown for your account or issuer. General current correspondence commonly uses P.O. Box 500, Newark, NJ 07101. Include your contact information, issuer, account registration, complaint history, copies of supporting documents, and the resolution requested.

Step 7: Contact the Issuing Company

If EQ is administering shares for a public company and the issue remains unresolved, contact that company’s Investor Relations or Corporate Secretary office. The issuer can sometimes help determine whether a request requires company authorization, whether a corporate action has affected the account, or whether the matter is actually controlled by the transfer agent.

Step 8: Escalate Regulatory Issues Appropriately

Transfer agents operate in a regulated securities environment. Serious unresolved issues involving securities records, transfer processing, or shareholder rights may be raised with the appropriate securities regulator, depending on the nature of the account and transaction. Keep all EQ correspondence, tracking records, statements, and issuer responses before submitting an external complaint.

Step 9: Preserve a Complete Written Record

Maintain copies of every form, statement, certificate record, mailing receipt, email, call note, and case number until the matter is fully resolved. Transfer-agent complaints often involve detailed ownership histories or tax records, so a complete timeline can materially improve the chances of an efficient resolution if a supervisor, issuer, regulator, attorney, or estate representative later needs to review the case.
