[SCHEDULE 13D/A] PC CONNECTION INC SEC Filing

Rhea-AI Filing Summary

Patricia Gallup and the David Hall Trust 2003 report combined beneficial ownership of 13,779,533 shares of PC Connection, Inc. (CNXN), representing 54.4% of the 25,337,145 shares outstanding as of September 15, 2025. The filing amends prior Schedule 13D disclosures and details holdings held directly by Ms. Gallup and across several trusts and an estate: 4,540,508 shares directly by Ms. Gallup, 6,879,962 shares by the David Hall Trust 2003, 162,093 shares by the Estate, plus additional holdings in the North Branch Trust, Abbott Brook Trust, Comack Trust-B, and shares held by Ms. Gallup's spouse.

The document explains historical transfers, estate-planning transfers and annuity distributions made for no consideration, including a September 15, 2025 annuity distribution of 1,093,163 shares from the Abbott Brook Trust to Ms. Gallup, and a September 15, 2025 contribution of 1,000,000 shares to Comack Trust-B. Aggregate cost bases for major blocks are disclosed. The filing states Ms. Gallup is the issuer's Chief Administrative Officer and Chairman and that no other plans or proposals are disclosed.

Positive

• Majority control continuity: Reporting Persons collectively maintain a >50% stake (54.4%), providing ownership stability and continuity of board influence.
• Transparent estate-planning disclosures: The filing details trust transfers, annuity distributions and cost basis step-ups, improving clarity on ownership provenance.
• No new takeover or disruptive proposals disclosed: The amendment states no current plans or proposals relating to change-in-control or other matters requiring disclosure.

Negative

• Concentrated ownership: Over 54% beneficial ownership by a single reporting person may limit minority shareholder influence.
• Potential future transfer risk: Multiple interrelated trusts and scheduled expirations (Abbott Brook Trust 2026, Comack Trust-B 2027) imply future ownership shifts that could change voting dynamics.

Insights

Corporate Governance Expert

TL;DR: The filing documents entrenched insider control—over 54% beneficial ownership—structured through trusts and estate transfers for governance and estate-planning purposes.

The amendment clarifies that Patricia Gallup, through direct ownership, trustee roles and beneficiary positions, effectively controls a majority stake (54.4%) of PC Connection, Inc.'s common stock. The filing details historical voting-trust arrangements, post-mortem transfers following Mr. Hall's death, and multiple inter-trust transfers and annuity distributions executed for no consideration. For governance, this concentration signals continued decisive influence by Ms. Gallup over director elections, corporate strategy and vote-sensitive corporate actions. The filing does not disclose any new takeover proposals, change-in-control transactions, or specific governance changes beyond estate planning. Material facts such as exact voting arrangements and timing of future transfers are stated without speculative intent.

Estate & Tax Planning Specialist

TL;DR: The disclosure reflects tax- and estate-driven reallocation of shares into trusts and annuity structures, with step-up-in-basis reported for certain blocks.

The Schedule 13D/A provides detailed descriptions of estate-planning transfers: a 2023 transfer of 6,879,962 shares to the David Hall Trust 2003, a 2024 contribution of 2,000,000 shares to the Abbott Brook Trust, and a 2025 distribution of 1,093,163 shares as an annuity. The filing reports step-ups in cost basis following Mr. Hall's passing for certain holdings, and reports nominal aggregate cost bases for other trust-held blocks. These entries are consistent with intergenerational wealth transfer and annuitization strategies; they explain changes in reported beneficial ownership percentages (including passive increases due to issuer share repurchases). The filing contains no tax advice or projections—only factual basis amounts and trust terms described at a high level.

In connection with the Issuer's initial public offering in March 1998, Ms. Gallup and Mr. Hall placed substantially all of the shares of Common Stock that they beneficially owned immediately prior to the public offering into the Voting Trust in exchange for voting trust receipts representing each share of Common Stock contributed to the Voting Trust. Mr. Hall passed away on November 14, 2020. Upon Mr. Hall's passing the shares of Common Stock directly and beneficially owned by him were transferred to the Estate and Ms. Gallup became the sole remaining trustee of the Voting Trust. As sole remaining trustee, Ms. Gallup had the authority to administer the Voting Trust and vote all of the shares held of record by the Voting Trust. On September 10, 2021, Ms. Gallup, as the sole remaining trustee of the Voting Trust, directed the Voting Trust be liquidated and the shares held of record by the Voting Trust be transferred to Ms. Gallup and the Estate as the holders of all of the outstanding Voting Trust Receipts, which was completed on September 21, 2021.

Item 4.	Purpose of Transaction
	Item 4 is amended and restated in its entirety as follows: The Reporting Persons hold a substantial position in the Issuer, which was primarily acquired by Patricia Gallup and David Hall at the founding of the Issuer. In connection with the Issuer's initial public offering in March 1998, Ms. Gallup and Mr. Hall placed substantially all of the shares of Common Stock that they beneficially owned immediately prior to the public offering into the Voting Trust in exchange for voting trust receipts representing each share of Common Stock contributed to the Voting Trust. Mr. Hall passed away on November 14, 2020. Upon Mr. Hall's passing the shares of Common Stock directly and beneficially owned by him were transferred to the Estate and Ms. Gallup became the sole remaining trustee of the Voting Trust. As sole remaining trustee, Ms. Gallup had the authority to administer the Voting Trust and vote all of the shares held of record by the Voting Trust. On September 10, 2021, Ms. Gallup, as the sole remaining trustee of the Voting Trust, directed the Voting Trust be liquidated and the shares held of record by the Voting Trust be transferred to Ms. Gallup and the Estate as the holders of all of the outstanding Voting Trust Receipts, which was completed on September 21, 2021. On February 13, 2023, Ms. Gallup's spouse gifted 275,000 shares of Common Stock to the North Branch Trust for no consideration. Under the trust agreement establishing the North Branch Trust, Ms. Gallup serves as sole trustee. The trust agreement establishing the North Branch Trust also provides that upon the passing of Ms. Gallup, voting and investment control over the shares of Common Stock held by the North Branch Trust would pass to the successor trustee as set forth in the trust agreement. The Estate, on March 13, 2023, transferred 6,879,962 shares of Common Stock to the David Hall Trust 2003 at the direction of Ms. Gallup, in her capacity as executor, for no consideration. Under the trust agreement establishing the David Hall Trust 2003, Ms. Gallup serves as sole trustee and is the sole lifetime beneficiary of the shares held by the David Hall Trust 2003 and holds voting and dispositive power over the 6,879,962 shares of Common Stock held directly by the David Hall Trust 2003. Following the completion of the administration of the Estate, the assets held by the David Hall Trust 2003 will be distributed to one or more trusts of which Ms. Gallup will be the sole lifetime beneficiary and a co-trustee with an additional co-trustee to be identified. On September 16, 2024, for estate planning purposes, Ms. Gallup contributed 2,000,000 shares of Common Stock to the Abbott Brook Trust for no consideration. Under the trust agreement establishing the Abbott Brook Trust, Ms. Gallup serves as sole trustee and sole annuitant of the Abbott Brook Trust and holds shared voting and dispositive power over the shares of Common Stock held directly by the Abbott Brook Trust. Ms. Gallup or, if she passes, her estate, receives an annual annuity amount from the Abbott Brook Trust. On September 15, 2025, the Abbott Brook Trust distributed 1,093,163 shares of Common Stock to Ms. Gallup as an annual annuity in accordance with the terms of the trust agreement for no consideration. As a result of this distribution, the Abbott Brook Trust holds less than 5% of the outstanding shares of Common Stock of the Issuer as of September 15, 2025. The Abbott Brook Trust is scheduled to expire on September 15, 2026 at which time the assets remaining in the Abbott Brook Trust will be distributed to a spillover trust. On September 15, 2025, under the trust agreement establishing the Comack Trust-B, Ms. Gallup serves as sole trustee and sole annuitant of the Comack Trust-B and holds shared voting and dispositive power over the shares of Common Stock held directly by the Comack Trust-B. Ms. Gallup or, if she passes, her estate, will receive an annual annuity amount from the Comack Trust-B. The Comack Trust-B is scheduled to expire on September 14, 2027 at which time the assets remaining in the Comack Trust-B will be distributed to a spillover trust. On September 15, 2025, Ms. Gallup gifted 3,500 shares of Common Stock to a charity for no consideration. The Issuer has historically maintained a share repurchase program for the purchase of shares of Common Stock from time to time. As a result of repurchases under this program from March 2025 through September 2025, the number of shares of outstanding Common Stock decreased, and consequently, the percentage of shares of Common Stock beneficially owned by the Reporting Persons as of September 15, 2025, passively increased. Ms. Gallup is the Chief Administrative Officer and Chairman of the Board of Directors of the Issuer. Except as disclosed in this Schedule 13D, none of the Reporting Persons currently has any other plans or proposals which relate to, or would result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto.
