[S-8] Tivic Health Systems, Inc. Employee Benefit Plan Registration

Rhea-AI Filing Summary

Tivic Health Systems, Inc. (TIVC) has filed a Form S-8 to register 511,117 additional shares of common stock for issuance under its 2021 Equity Incentive Plan. The new shares arise from three sources: (i) 53,389 shares added when the plan was amended and restated on Aug 9 2024; (ii) 32,728 shares added via the plan’s annual “evergreen” increases on Jan 1 of 2022-2025; and (iii) 425,000 shares added through a further amendment on Jun 30 2025.

The evergreen feature allows an automatic yearly increase through Jan 1 2031 equal to the lesser of 5 % of outstanding common stock or a board-determined amount. The company previously registered 774 shares (post-split basis) for its 2021 and 2017 plans on Nov 12 2021.

Two reverse stock splits have been effected and retroactively reflected: a 1-for-100 split on Aug 23 2023 and a 1-for-17 split on Mar 7 2025. Tivic is classified as a non-accelerated filer, smaller reporting company, and emerging growth company. No financial performance data or new fundraising transactions are included; the filing strictly covers share registration for employee compensation purposes.

Positive

• Enhanced talent retention: Additional shares expand the pool for stock-based awards, helping recruit and retain employees in a competitive market.
• Clear disclosure: Company provides detailed share breakdown and incorporates prior filings, improving transparency for investors.

Negative

• Potential shareholder dilution: 511,117 new shares will increase the fully diluted share count once issued.
• Frequent share consolidations: Two reverse stock splits since 2023 highlight ongoing share-structure adjustments.

Insights

Securities Analyst

TL;DR – Registers 0.51 M new incentive shares; supportive for talent, mildly dilutive for holders.

The S-8 enlarges the 2021 Equity Incentive Plan to roughly 511 k shares—material for a micro-cap issuer yet routine in structure. The breakdown shows most shares (425 k) stem from the June 2025 amendment, signalling the board’s commitment to equity-based compensation. While incentive capacity can aid retention and growth, it also expands the fully diluted share count and may weigh on per-share metrics once options/RSUs vest. Prior reverse splits underscore an already low share base; thus, incremental dilution could be proportionally meaningful. No capital is raised via this filing, so cash runway is unaffected.

Corporate Governance Expert

TL;DR – Filing is procedurally standard; evergreen feature remains intact through 2031.

Governance-wise, the company adheres to SEC rules by incorporating prior filings and detailing amendments. The evergreen cap of 5 % per year is typical for small-cap tech issuers, but investors should monitor future automatic increases. Two substantial reverse splits within 19 months illustrate sensitivity to listing or price thresholds; continued issuance under the plan could necessitate further authorization down the line. Overall impact is neutral absent other strategic moves.

The Company initially registered 552 shares and 222 shares of Common Stock reserved for issuance under the 2021 Plan and the Company’s 2017 Equity Incentive Plan (the “2017 Plan”), respectively, on Form S-8 filed with the Securities and Exchange Commission (the “Commission”) on November 12, 2021 (Commission File No. 333-261044), the contents of which are hereby incorporated by reference into this Registration Statement, except to the extent supplemented, amended or superseded by the information set forth in this Registration Statement or by any subsequently filed document.

Item 9. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

	(i)	to include any prospectus required by Section 10(a)(3) of the Securities Act;
	(ii)	to reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement;
	(iii)	to include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this registration statement;

	provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.
	(2)	that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and
	(3)	to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

	(b)	The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
