TACTILE SYSTEMS TECHNOLOGY, INC.

Insider Trading Policy

Amended: February 13, 2025

Federal and state securities laws prohibit individuals from trading in the securities of a company while they are aware of material information about that company that is not generally known or available to the public. Such trading is often referred to as “insider trading.” The purpose of this Insider Trading Policy is to prevent insider trading or allegations of insider trading, and to protect the reputation for integrity and ethical conduct of Tactile Systems Technology, Inc. (the “Company”).

Applicability of Policy

A.Material Nonpublic Information means material information (described below) that has either not been disclosed to the public generally, or has been disclosed so recently that sufficient time has not yet passed to allow the information to become widely available among investors and the financial community.

B.Material Information means information about a company that would be expected to affect the investment or voting decision of a reasonable investor, or information that could reasonably be expected to have an effect on the price of that company’s securities. Examples of what might be considered material information are listed later in this Policy.

C.Covered Individuals. This Policy applies to:

1. Company Personnel. All directors, officers and employees of the Company and any subsidiary (“Company Personnel”), as well as members of their immediate families and others living in the same household.

2. Consultants and Advisors. All consultants and advisors to the Company and any subsidiaries whose work for the Company brings them into contact with material nonpublic information.

3. Related Parties. Any other person or entity, including a trust, corporation, partnership or other association, whose transactions in Company securities are directed by any person covered by paragraph C(1) or C(2) or are subject to that person’s influence or control.

The individuals and entities described in paragraphs C(1), C(2) and C(3) are referred to as “Covered Persons.”

D.Covered Companies. This Policy applies to trading in the securities of:

E.Covered Transactions. The securities trading that this Policy covers includes purchases and sales of common stock, options to acquire common stock and any other securities the Company may issue from time to time, such as preferred stock, warrants and convertible debentures, and purchases and sales of derivative securities relating to the Company’s stock, whether or not issued by the Company, such as exchange-traded options. Trading covered by this Policy may or may not include transactions under Company-sponsored plans as follows:

1. Stock Option Exercises. The Policy’s trading restrictions do not apply to the purchase of Company stock through the exercise of stock options granted by the Company. The trading restrictions do apply to any contemporaneous (such as a sale through a broker as part of a cashless exercise of the option) or subsequent sale of Company stock acquired through an option exercise.

2. Employee Stock Purchase Plan Purchases. The Policy’s trading restrictions do not apply to the purchase of Company stock through any Employee Stock Purchase Plan that the Company may maintain from time to time (but the Policy’s trading restrictions do apply to any election to participate in such plan, any election to change the level of participation in such plan or the sale of any shares acquired under such plan).

3. Restricted Stock/Unit and Performance Stock/Unit Awards. The Policy’s trading restrictions do not apply to the vesting of restricted stock/units or performance stock/units, or to the exercise of a tax withholding right pursuant to which the person elects to have the Company withhold shares of stock to satisfy tax withholding requirements upon vesting. The trading restrictions do apply to any market sales of shares, such as a sale-to-cover.

4. Certain Gifts. The Policy’s trading restrictions do not apply to a bona fide gift of Company stock so long as either (i) the recipient of the gift is subject to the same trading restrictions under this Policy as are applicable to you, or (ii) you otherwise have no reason to believe that the recipient intends to sell the securities immediately or during a period when you would not be permitted to trade pursuant to the terms of this Policy.

F.Transactions by the Company. From time to time, the Company may engage in transactions in its own securities, including repurchasing its shares in the open market. It is the Company’s policy that any transactions by the Company will comply with applicable laws with respect to insider trading and not be subject to the express provisions of this Policy.

Statement of Policy

Insider trading involves trading at any time when the person making the purchase or sale is aware of material nonpublic information regarding the company whose securities are being traded. If you have a doubt or question about whether you are aware of or in possession of material nonpublic information concerning the Company or another company, you should contact the Company’s Chief Financial Officer.

A.No Trading on Material Nonpublic Information

1. Company Securities. If you are a Covered Person, you must not purchase or sell any Company securities, or otherwise advise or assist any third party trading Company securities, while you are aware of material nonpublic information regarding the Company.

2. Other Companies’ Securities. If you are a Covered Person and you obtain material nonpublic information about any other publicly-held company as a result of your work on behalf of the Company or any subsidiaries, you must not trade in that company’s securities.

B.No Disclosure to Others Who Might Trade. If you are a Covered Person, you must not communicate material nonpublic information to any person who does not need that information for a legitimate business purpose, or recommend to anyone the purchase or sale of securities when you are aware of material nonpublic information about the company involved. This practice, known as “tipping,” also violates the securities laws and can result in the same civil and criminal penalties that apply to insider trading, even though you did not actually trade and did not benefit from another’s trading.

C.Protect Material Nonpublic Information. In order to reduce the possibility that material nonpublic information will be inadvertently disclosed:

You must treat material nonpublic information as confidential, exercise the utmost caution in preserving the confidentiality of that information, and should not discuss it with any other person who does not need to know it for a legitimate business purpose.

You should refrain from discussing material nonpublic information relating to the Company or any public company in public places where such discussions can be overheard.

If you become aware of any leak of material nonpublic information, whether inadvertent or otherwise, you should report the leak immediately to the Company’s Chief Financial Officer.

D.Specific Material Developments. From time to time, material developments known only to a limited number of Company personnel may occur to cause the Company to impose on an appropriate group of Company personnel additional restrictions on trading. You will be notified if you become part of such a group, and you should not disclose to others the fact that you have been so notified and that restrictions on trading have been imposed.

Exceptions for Approved 10b5-1 Plans

Transactions in Company securities that are executed pursuant to a 10b5-1 plan (or modifications thereto) approved in writing in advance by the Chief Financial Officer are not subject to prohibition on trading on the basis of material nonpublic information or the restrictions in the attached Addendum relating to the pre-clearance approval process or window periods.

Rule 10b5-1 provides an affirmative defense from insider trading liability under the federal securities laws for trading plans that meet certain requirements. In general, a 10b5-1 plan must be entered into (or modified) in good faith, not as part of a plan or scheme to evade the prohibitions of the insider trading rules and during a time when you are not aware of material nonpublic information. The plan must also provide for a cooling-off period for at least the minimum period required under, and must comply with all other applicable provisions of, Rule 10b5-1(c) of the Securities Exchange Act of 1934, as amended.

Once the plan is adopted, you must not exercise any influence over the securities subject to the plan, including the amount of securities to be traded, the price at which they are traded or the date of the trade. The plan must either specify (including by formula) the amount, pricing and timing of the transactions in advance or delegate discretion on those matters to an independent party.

Additional Restrictions on Corporate Insiders

If you are a Corporate Insider (directors and Section 16 officers of the Company and other officers and key employees of the Company and any subsidiaries who have been designated as Corporate Insiders by the Chief Financial Officer), you are subject to additional restrictions on trading Company securities as set out in the attached Addendum. The Company may also, from time to time, impose on all or an appropriate group of Covered Persons additional restrictions on trading Company securities when circumstances warrant. These additional restrictions will be communicated by the Chief Executive Officer or Chief Financial Officer.

Disciplinary Action and Potential Civil and Criminal Penalties

A.Disciplinary Action. Company personnel who fail to comply with this Policy will be subject to appropriate disciplinary action, which may include ineligibility to participate in the Company’s equity incentive plans or termination of employment.

B.Civil and Criminal Penalties. The penalties for violating insider trading laws are severe. If you trade on (or tip) material nonpublic information, you are subject to civil penalties of up to three times the profit gained or loss avoided, criminal fines of up to $5,000,000 and up to 20 years imprisonment. If the Company fails to take appropriate steps to prevent insider trading, the Company and its directors, officers and other supervisory personnel may be subject to “controlling person” liability and potential civil and criminal penalties.

Material Information

There are various categories of information that are particularly sensitive and, as a general rule, will presumptively be considered material. Examples of such information include:

Inquiries

Inquiries regarding any of the provisions or procedures of this Insider Trading Policy should be directed to the Chief Financial Officer.

ADDENDUM

Additional Requirements and Responsibilities for Corporate Insiders

B.Persons Covered.

1. Directors and Section 16 Officers. All provisions of this Addendum apply to the directors and officers of the Company subject to Section 16 of the Securities Exchange Act of 1934 (referred to herein as “Section 16 Officers”).

2. Other Officers and Key Employees. Designated provisions of this Addendum apply to the other officers of the Company and to designated key employees. These other officers and key employees, whose duties cause them to regularly have access to material nonpublic information about the Company, will be notified by the Chief Financial Officer that they are subject to this Addendum.

3. Related Parties. If you are covered by paragraph B.1 or B.2, then this Addendum also applies to the same extent to your immediate family members and other individuals living in your household, and to any other person or entity, including a trust, corporation, partnership or other association, whose transactions in Company securities are directed by you or are subject to your influence or control.

The individuals and entities described in paragraphs B(1), B(2) and B(3) above are collectively referred to as “Corporate Insiders.”

C.Blackout Periods for all Corporate Insiders

1. Trading Not Permitted During Blackout Periods. If you are a Corporate Insider, you may not purchase, sell or otherwise trade Company securities during the period beginning on the 15th day of the last calendar month of each fiscal quarter and continuing through the second trading day following the public release of the Company’s financial results for that fiscal quarter. If a Corporate Insider wishes to trade outside of a blackout period, the person may do so only if he or she is not then aware of any material nonpublic information. In addition, before Corporate Insiders may trade outside of any blackout period, they must comply with the notification and pre-clearance procedures described below.

2. Illustration – Blackout Period: If financial results for the quarter ended March 31 are released after the stock market closes on April 26, then Corporate Insiders are prohibited from trading from March 15 through April 28, but could trade from April 29 through June 14, assuming that April 27 and 28 are trading days on the Nasdaq Stock Market and assuming that they are not aware of material nonpublic information.

D.Required Preclearance of Trades

1. Notices of Intended Transaction and Requests for Approval. If you are a Corporate Insider, you may not engage in any transaction involving Company securities without first obtaining pre-clearance of that transaction from the Company’s Chief Executive Officer, Chief Financial Officer or other individual designated by the Company’s Chief Financial Officer or board of directors (collectively, the “Plan Administrators”). Prior to initiating any transaction in Company securities, you must deliver to the Chief Financial Officer a written notice in the form prescribed by the Chief Financial Officer describing

any intended transaction in Company securities by you during a permitted trading period. Notices of intended transactions and requests for approval may be delivered by e-mail.

2. Clearance to Proceed with a Transaction. Prior to completing a transaction, a Corporate Insider must receive clearance of one of the Plan Administrators. Clearance in response to a written request for approval will generally be valid until the end of the current permitted trading period, unless an earlier deadline is imposed by one of the Plan Administrators, but a clearance may be revoked at any time without notice.

E.Additional Restrictions on Trading by Directors and Section 16 Officers

1. Restricted Transactions. Directors and Section 16 officers, or their designees, are also prohibited from engaging in the following transactions with respect to Company securities:

purchasing Company securities on margin, holding any Company securities in a margin account or otherwise pledging Company securities;

short sales of Company securities (selling securities not owned at the time of sale);

buying or selling put or call options or other derivative securities based on Company securities;

purchasing any financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) or otherwise engaging in transactions that are designed to or have the effect of hedging or offsetting any decrease in the market value of Company securities, except that these restrictions do not prevent general portfolio diversification or investing in broad-based index funds; and

engaging in limit orders or other pre-arranged transactions that execute automatically, except for “same-day” limit orders and approved 10b5-1 plans.

2. Short-swing Trading Restrictions. Directors and Section 16 officers of the Company must also comply with the reporting obligations and limitations on short-swing trading transactions imposed by Section 16 of the Securities Exchange Act of 1934. Among other things, Section 16 requires directors and Section 16 officers to pay over to the Company any profit realized from any purchase and sale (in either order) of Company securities that occur within six months of each other. Section 16 and its related rules are very complex, and the Company will provide to each director and Section 16 officer a separate memorandum discussing compliance with Section 16 and its related rules.
