Business operations and products

Petros Pharmaceuticals positions its operations across several areas:

• Prescription therapeutics focused on men’s health, particularly treatments for erectile dysfunction and other related indications.
• Rx-to-OTC transition platforms designed to allow consumers to self-select products appropriately and safely under regulatory frameworks.
• Software-as-a-Service (SaaS) and related digital platforms — including self-selection questionnaires, telemedicine integrations, and, in some announcements, AI-enabled decision-support tools intended to support regulatory-compliant OTC switches.
• Licensing and distribution arrangements with partners for specific product candidates or branded offerings.

The firm has discussed activities related to branded erectile dysfunction products such as programs associated with Stendra-related approaches, plus development of self-selection methodologies aligned with FDA guidance for Rx-to-OTC switches.

Research and development / Clinical studies

Petros has reported clinical or real-world studies and self-selection study initiatives aimed at demonstrating the safety and effectiveness of self-selection platforms and consumer-directed access mechanisms. These programs are intended to inform regulatory conversations and support applications for Rx-to-OTC transitions when appropriate.

• Study outcomes and status: The company has disclosed design details and interim observations for self-selection and safety studies in press summaries and filings. Exact study endpoints, sample sizes, and final statistical results are normally published in regulatory submissions or detailed press releases.
• Regulatory pathway: Rx-to-OTC switches in the U.S. principally follow FDA guidance and may require data showing consumers can self-diagnose and self-select without a clinician’s intervention. Petros’ programs are framed to generate such evidence.

As of 2026-01-26, according to company press summaries and financial-data hubs, Petros continued to emphasize R&D focused on regulatory-compliant self-selection and product development; however, readers should consult up-to-date filings for final trial results and regulatory filings.

Stock and market information

The equity of Petros Pharmaceuticals trades under the ticker PTPI and is commonly referenced as ptpi stock by investors and market-data services. Due to the company’s microcap size, the stock typically exhibits characteristics associated with penny stocks: low share price, relatively small market capitalization, limited float, and higher volatility and illiquidity relative to larger, exchange-listed companies.

Trading status and exchange history

• Nasdaq listing history: Petros was previously listed on Nasdaq. In 2025, Nasdaq issued a determination related to the company’s continued listing, and the company subsequently engaged in appeals or remediation steps. Those developments ultimately led to the company no longer trading on Nasdaq.
• OTC Markets trading: Following the Nasdaq sequence, ptpi stock transitioned to quotation and trading on OTC Markets. OTC trading is characteristic for many microcap equities after delisting events.

As of 2026-01-26, according to Nasdaq and OTC market profiles in public reporting, PTPI’s public trading venue is OTC Markets; investors should review official OTC quotes and market-data feeds for up-to-date trade information.

Price performance and historical data

Historical pricing for ptpi stock shows periods of pronounced volatility commonly associated with speculative small-cap equities. Data aggregators list wide 52-week ranges and prior spikes or drawdowns tied to specific announcements, financings, or low-volume trading dynamics.

• Historical extremes: Historical pricing data platforms report prior intraday spikes and steep corrections over multiyear periods, consistent with the microcap/penny-stock profile.
• Typical volatility: Low float and limited liquidity can produce outsized percentage moves on news, thin-volume trading sessions, or promotional cycles.

For point-in-time price history and charts, consult market-data providers such as MacroTrends or Yahoo Finance for verified historical time series and adjusted price points.

Market metrics

Common data points investors monitor for ptpi stock include market capitalization, average daily volume, 52-week high/low, and basic per-share metrics. Microcaps often have:

• Market capitalization: typically in the low millions to tens of millions range for penny-stock classifications; exact figures vary by date and data provider.
• Average daily volume: frequently low, with spikes on specific news events.
• 52-week high / low: wide ranges are typical; check current market-data pages for verified figures.
• P/E and EPS: many microcaps report negative earnings, making P/E not meaningful; earnings-per-share can be negative in recent periods.
• Short interest and liquidity: short-interest data may be limited or sparse; low liquidity increases bid-ask spreads and execution risk.

As of 2026-01-26, according to Yahoo Finance and Finviz profiles, ptpi stock metrics reflect microcap characteristics—investors should view published metrics on the date of their inquiry because figures can change rapidly.

Financial performance

Petros Pharmaceuticals’ financial statements, as published in periodic filings, typically show modest revenue relative to operating expenses and net losses consistent with a company investing in product development and platform buildout.

• Revenue and profitability: recent reported periods have included limited or early-stage revenues and ongoing operating losses. TTM revenue figures, net losses, and cash-burn trends are reported in quarterly and annual statements.
• Cash and liquidity: cash position and working capital levels are material to a small company’s ability to continue operations; Petros has used equity financings and capital-raising activities to support operations.
• Financing and dilution: small public companies commonly issue new shares or convertible instruments to raise capital, which can dilute existing shareholders; Petros has engaged in equity transactions reported in filings.

Recent results and guidance

As of 2026-01-26, according to company filings and financial-data summaries reported by CNBC and Reuters, the company’s most recent quarterly reports indicated continued investment in R&D and platform development, with management commentary focusing on regulatory workstreams and partnership development rather than near-term profitability guidance. Readers should consult the company’s most recent quarterly (Form 10-Q) or annual (Form 10-K) filings for exact figures and management remarks.

Corporate governance and management

The company’s corporate governance disclosures identify the board of directors, executive officers (including CEO and CFO roles), and material insider-ownership levels. Small public companies often have higher insider ownership percentages than large-cap companies, which can influence corporate decision-making and capital decisions.

• Board and executives: names and biographies are available in annual proxy statements and SEC filings.
• Insider transactions: filings report insider purchases, sales, and option grants; these should be verified on EDGAR or the company’s investor relations materials.
• Governance matters: exchange delisting proceedings, appeals, or material related-party transactions are typically disclosed in periodic filings and can be governance focal points.

As of 2026-01-26, company profiles on Reuters and Nasdaq summarise board composition and executive leadership; consult the latest proxy or Form 10-Q for detailed governance disclosures.

Subsidiaries and corporate structure

Petros has disclosed subsidiaries and related entities that were part of its historical operating structure. One example referenced in public summaries is Metuchen Pharmaceuticals (and affiliated entities), which was cited in corporate reorganization statements and, in some periods, deconsolidation announcements.

Investors should review recent Form 10-K/10-Q filings for up-to-date information on subsidiary relationships and accounting treatment.

Partnerships, collaborations and technology platforms

Petros has announced strategic collaborations to advance its self-selection and Rx-to-OTC objectives. Reported partners include clinical research organizations, technology vendors and data providers. Public summaries mention collaborations focused on:

• Self-selection and telemedicine integration.
• Data and analytics providers to support consumer screening algorithms.
• SaaS delivery and potential Software-as-a-Medical-Device (SaMD) pathways for regulatory compliance.

As of 2026-01-26, StockTitan and company press materials summarized that Petros had engaged third-party technology and analytics partners to operationalize its self-selection platform and to prepare evidence packages aligned with FDA guidance.

Regulatory and legal matters

Regulatory context is central to Petros’ business model: transitioning prescription medicines to OTC availability requires alignment with regulatory standards and a robust evidence base.

• FDA Rx-to-OTC guidance: regulatory pathways generally require demonstration that consumers can self-diagnose and self-select a product with adequate safety margins and appropriate labeling. Petros has positioned its self-selection studies to support such pathways.
• Exchange and listing actions: Nasdaq’s delisting determination and subsequent transition to OTC were material regulatory/market events for the company. These events and any appeals are recounted in public filings.
• Litigation and compliance: any material legal proceedings or regulatory enforcement actions are required to be disclosed in SEC filings; reviewers should consult the company’s most recent reports for standing matters.

As of 2026-01-26, reporting in Nasdaq company pages and Reuters detailed the delisting and related procedural steps; investors should check the company’s SEC filings for disclosure of any active litigation or regulatory inquiries.

• High volatility: share price can move substantially on limited news or thin trading volume.
• Low liquidity: limited float and small average daily volume increase execution risk and widen bid-ask spreads.

• Dilution risk: capital-raising through equity issuance or convertible securities is common among microcaps and can materially dilute current shareholders.
• Information asymmetry and retail speculation: heightened retail discussion and promotional activity can amplify price moves that are not tied to fundamentals.
