Inside Carlsmed's IPO: Personalized Spine Tech Company Eyes $100M+ Raise

Carlsmed, Inc., a next-generation medical device company, has filed for its initial public offering (IPO) with the SEC. This Southern California-based firm is seeking to raise capital to propel its personalized spine treatment platform into more hospitals and surgical centers across the United States and beyond.

The offering involves 6.7 million shares of common stock, priced between $14.00 and $16.00 per share, and will trade under the ticker symbol CARL on the Nasdaq Global Select Market. The company also granted underwriters a 30-day option to purchase an additional 1,005,000 shares, which could push proceeds even higher.

What Does Carlsmed Do?

Carlsmed is on a mission to revolutionize spinal surgery through precision healthcare. Specifically, the company has developed a proprietary platform that leverages artificial intelligence and advanced imaging to create personalized surgical plans and 3D-printed implants for patients suffering from adult spinal deformity (ASD) and degenerative spine disorders.

Its flagship product, Aprevo, allows for a tailored approach to spinal alignment by generating patient-specific interbody fusion devices. Instead of using off-the-shelf implants, which may not match every patient’s unique spinal curvature, Aprevo aims to improve outcomes by fitting the implant to the patient, not the other way around.

Here’s what makes Carlsmed’s approach compelling:

• AI-Powered Planning: Machine learning analyzes individual imaging data to develop the optimal surgical plan.

• 3D Printing: Every implant is custom-fabricated to match a patient’s spine, reducing misalignment and enhancing post-surgical recovery.

• Regulatory Support: Aprevo is FDA-cleared, with growing traction in both clinical and commercial use.

The company believes this precision approach reduces complications, speeds up recovery, and significantly cuts down on revision surgeries, a common and costly outcome in traditional spinal fusion.

Inside the IPO: Numbers That Matter

Let’s break down the offering’s structure:

• Offering Size: 6,700,000 shares

• Expected Price Range: $14.00 to $16.00

• Maximum Gross Proceeds (excluding overallotment): Approximately $107.2 million

• Ticker Symbol: CARL

• Stock Exchange: Nasdaq Global Select

• Underwriters: BofA Securities, Goldman Sachs & Co. LLC, Piper Sandler, Truist Securities, BTIG

• 30-Day Underwriters’ Option: 1,005,000 additional shares

Assuming the midpoint pricing of $15 per share and full subscription, this IPO could bring in over $115 million before underwriting fees and expenses, a crucial funding round for Carlsmed’s next growth phase.

Strategic Use of IPO Proceeds

Carlsmed plans to allocate the funds from the IPO in the following areas:

1. Expand Commercialization: Hiring and training more sales reps to grow surgeon adoption and hospital contracts.

2. Manufacturing Infrastructure: Scaling up the production of custom implants using advanced 3D printing.

3. Product Development: Continued R&D, including enhancements to the Aprevo platform and expansion into adjacent spinal procedures.

4. Regulatory Expansion: Gaining additional clearances to treat more spinal conditions and enter international markets.

5. Working Capital & General Purposes: Supporting the company’s operations, including IT systems and customer support infrastructure.

Who’s Investing in Carlsmed?

What really adds weight to this IPO is the high-profile investor interest. According to the S-1 filing:

• B Capital Group, a global investment firm co-founded by Facebook co-founder Eduardo Saverin, has indicated interest in purchasing up to $20 million worth of shares.

• U.S. Venture Partners (USVP), a leading early-stage VC firm known for backing health and enterprise tech startups, has shown intent to buy approximately $11 million in shares.

These indications are non-binding, but they reflect confidence from experienced institutional investors. In fact, both firms have historically supported Carlsmed in earlier private rounds and are signaling their long-term belief in the company’s future.

Adding to that, Carlsmed’s board includes individuals connected to these firms, showing tight alignment between management and investors. Their continued participation reduces uncertainty and adds a layer of credibility for retail and institutional buyers alike.

Key Partnerships and Industry Collaborations

While Carlsmed is not yet a household name, it has steadily built a presence through strategic clinical and distribution relationships.

• Clinical Trials and Collaborations: The company has worked with major academic medical centers to conduct studies validating the efficacy of Aprevo. These collaborations help improve outcomes and generate essential clinical data for broader adoption.

• Hospital Integration: Carlsmed integrates its AI-driven surgical planning system with existing imaging and EHR infrastructure at hospitals, making adoption smoother for clinical teams.

• Technology Partnerships: Carlsmed’s planning software is designed to be compatible with imaging systems used by top hospitals, setting the stage for potential integrations with larger surgical robotics or navigation systems.

These partnerships are vital not just for sales, but also for Carlsmed’s long-term vision of becoming a full-stack surgical planning and execution platform.

How is Carlsmed Performing Financially?

As with most medical device startups, Carlsmed is not yet profitable. The company’s financial statements reveal:

• Revenue: Limited, reflecting the early commercialization stage

• Operating Losses: Substantial, as Carlsmed continues to invest in R&D, product iteration, regulatory compliance, and sales infrastructure

• Cash Flow: The IPO is crucial to extend Carlsmed’s runway and accelerate commercialization

What’s worth noting is that Carlsmed isn’t in financial trouble, rather, it is strategically burning capital to capture market share and build out its offering. Its existing venture funding has kept the company afloat until now, and the IPO aims to turbocharge that trajectory. Investors should approach Carlsmed as a high-growth, high-upside med-tech play, not a revenue-generating cash cow, at least not yet.

Ownership, Voting Power, and Control

After the IPO, insiders, including Carlsmed’s executive team, directors, and early investors, will still own about 57.1% of the company. This level of control means they can influence key corporate decisions, such as mergers, board appointments, and amendments to governing documents.

While some may see this as a governance red flag, it also suggests that the founders and early backers are deeply invested in the company’s success and long-term vision. Investors should weigh this carefully, especially if they prefer decentralized or more shareholder-friendly structures.

Risks Worth Reviewing

No IPO is risk-free, and Carlsmed's filing outlines a few critical ones:

• Regulatory Delays or Failures: Future products must pass through FDA or international health agency approval, which can be lengthy and costly.

• Market Adoption: Convincing surgeons to switch to personalized implants is not a given, and uptake depends on evidence, training, and workflow alignment.

• Competitive Pressure: Larger, well-funded med-tech giants like Medtronic or Stryker could either outpace or attempt to acquire firms like Carlsmed.

• IP and Legal Risks: As a technology-driven company, Carlsmed must continuously protect its intellectual property and navigate potential litigation.

In Summary

Carlsmed’s IPO is a significant moment for a company betting big on the future of personalized spine care. With next-gen tech, FDA clearance, investor interest, and early commercial traction, the fundamentals are strong. However, this is still a growth-stage med-tech play, meaning it comes with substantial risk alongside the upside.

For investors seeking early exposure to innovation in digital surgery and medical AI, Carlsmed is one to watch closely. For those more risk-averse or seeking established profitability, a wait-and-see approach may be more prudent.
