Interactive Strength Inc. (NASDAQ: TRNR) is expanding its fitness-equipment business through another acquisition. On July 7, 2026, the company signed a definitive agreement to acquire STEPR, Inc., a connected stair-climbing fitness equipment company.
The transaction is expected to make STEPR the fifth major fitness brand in Interactive Strength’s portfolio, alongside Wattbike, Ergatta, CLMBR and FORME. The deal is expected to close in Q4 2026, subject to customary closing conditions, including completion of STEPR’s financial audit.
The acquisition is particularly important because STEPR is already a profitable business. Interactive Strength expects STEPR to generate more than $15 million in revenue during 2026. Following the planned acquisition, TRNR has raised its 2026 pro forma revenue outlook to more than $50 million and expects the combined company to reach Adjusted EBITDA profitability in Q4 2026, assuming the transaction closes as planned.

Who Is Interactive Strength?
Interactive Strength Inc. is a U.S.-based fitness equipment and technology company listed on Nasdaq under the ticker TRNR.
The company is building a multi-brand fitness platform by acquiring premium fitness businesses and operating them together. Its strategy is different from simply developing one fitness product. Instead, Interactive Strength wants to own several specialized brands covering different areas of exercise and training.
Its portfolio includes:
- Wattbike – performance-focused indoor cycling equipment
- Ergatta – connected rowing and game-based fitness
- CLMBR – vertical climbing fitness equipment
- FORME – smart strength, mobility and digital training
- STEPR – connected stair-climbing equipment, pending acquisition
Interactive Strength says its goal is to build a global, multi-brand fitness equipment platform through disciplined acquisitions of profitable and premium fitness businesses.
What Is STEPR?
STEPR is a fitness equipment company focused primarily on stair climbing.
The company was founded in 2021 with the goal of making stair climbing more accessible for homes and commercial gyms. Its machines combine traditional stair-climbing exercise with connected technology and digital content.
STEPR offers products ranging from home-focused machines to commercial equipment. Its connected STEPR+ model includes a 27-inch HD touchscreen, Bluetooth and Wi-Fi connectivity, on-demand workout content and entertainment features.
The company also emphasizes a compact design that can fit into many home environments. Its machines are designed around an approximately eight-foot ceiling requirement and can fit through standard doorways.
Why Is Interactive Strength Buying STEPR?
The acquisition fits directly into Interactive Strength’s existing strategy.
Instead of building a stair-climbing business from scratch, TRNR can acquire an existing brand that already has products, customers, distribution relationships and market recognition.
STEPR also adds a fitness category that is different from TRNR’s existing brands.
For example:
- Wattbike focuses on cycling.
- Ergatta focuses on rowing.
- CLMBR focuses on climbing.
- FORME focuses on strength and digital training.
- STEPR adds stair climbing.
This gives Interactive Strength a broader range of fitness products without relying on a single category.
STEPR Has Already Built a Retail Network
One of the interesting parts of the deal is STEPR’s existing distribution.
The company sells directly to consumers and has relationships with major fitness and retail channels, including Dick’s Sporting Goods, Rogue Fitness, Johnson Fitness and Scheels, according to transaction materials and company disclosures.
This is important because Interactive Strength can potentially use STEPR’s existing sales channels while also introducing the brand to its broader commercial and international network.
Acquisition Deal Structure
The headline number can be slightly confusing.
Interactive Strength has described the transaction as having a $6.7 million base transaction value, but the full consideration can become substantially larger if STEPR meets future performance targets.
The base structure includes:
- $2.2 million of cash and debt refinancing at closing
- $1.5 million of debt for working capital
- $3 million in TRNR equity
The equity component is designed to remain locked up for a period, helping reduce immediate selling pressure and aligning the sellers with the future performance of the combined company.
The SEC filing provides the more detailed legal structure. At closing, Interactive Strength plans to issue approximately $6 million of Series F-1 preferred stock, $10.5 million of Series F-2 preferred stock and $2.5 million of Series F-3 preferred stock, with the final value subject to performance-based scaling factors.
This is why the transaction should not simply be described as a straightforward $6.7 million acquisition.
Additional Payments Depend on STEPR’s Performance
A major feature of the transaction is that a significant portion of the potential consideration depends on STEPR’s future performance.
The first performance period runs from July 1, 2026, to June 30, 2027.
The second runs from July 1, 2027, to June 30, 2028.
The value of certain preferred-stock consideration will be adjusted according to STEPR’s EBITDA performance during these periods. The first target is based on EBITDA up to $4 million, while the second is based on EBITDA up to $7 million. Another portion is linked to specific synergy targets.
In simple terms, Interactive Strength is saying:
If STEPR performs well, the sellers can receive more value. If performance is weaker, the additional consideration can be reduced.
That structure can help protect TRNR shareholders from paying a large amount upfront for growth that may not materialize.
Potential Total Consideration Could Be Much Higher
The acquisition’s potential value is therefore significantly higher than the $6.7 million base transaction.
According to the transaction structure, STEPR could receive:
- Up to $3 million of additional TRNR equity based on the first EBITDA target.
- Up to $10.5 million of additional TRNR equity based on the second EBITDA target.
- Up to another $2.5 million based on specified synergies.
That means the additional performance-linked consideration could reach $16 million, although these amounts are not guaranteed and depend on STEPR achieving the required targets.
This performance-based structure is one of the most important aspects of the acquisition.
Why the Deal Could Be Attractive for TRNR
There are several potential advantages.
1. STEPR Is Already a Revenue-Generating Business
Interactive Strength is not acquiring only an idea or early-stage product.
STEPR already sells fitness equipment and has established retail relationships. The company expects STEPR to generate more than $15 million of revenue in 2026.
2. STEPR Is Profitable
The company has described STEPR as a profitable, fast-growing connected stair-climbing business.
That matters because Interactive Strength has been trying to build a portfolio of businesses that can eventually generate cash flow rather than continually requiring large amounts of capital.
3. New Fitness Category
STEPR gives TRNR exposure to stair climbing, a category that is different from cycling, rowing, climbing and digital strength training.
This makes the overall portfolio more diversified.
4. Performance-Linked Acquisition
A large part of the potential acquisition consideration depends on future results.
This means Interactive Strength does not have to pay the maximum potential value immediately.
5. Potential Cross-Selling Opportunities
Interactive Strength already owns multiple fitness brands.
There could be opportunities to combine technology, content, distribution, customer relationships and commercial sales across the portfolio.
However, these are potential benefits rather than guaranteed results.
Interactive Strength’s Acquisition Strategy
STEPR is not the company’s first major acquisition.
In 2025, Interactive Strength completed its acquisition of Wattbike, expanding into performance cycling.
In March 2026, it completed the acquisition of Ergatta for approximately $13.3 million. The Ergatta transaction also used a combination of cash, deferred consideration and preferred stock, showing that performance-linked acquisition structures are already part of TRNR’s strategy.
The STEPR deal therefore appears to be part of a broader plan rather than a standalone transaction.
The company has described itself as an operating company that acquires and runs premium fitness brands, with the intention of using the combined platform to support additional acquisitions.
Revenue Outlook After the STEPR Deal
The STEPR acquisition significantly changes Interactive Strength’s revenue outlook.
Before the deal, the company had expected 2026 pro forma revenue of more than $30 million.
After announcing STEPR, Interactive Strength increased its 2026 pro forma revenue guidance to more than $50 million, representing a major increase in its outlook.
STEPR alone is expected to contribute more than $15 million of revenue in 2026.
The company also expects to reach Adjusted EBITDA profitability in Q4 2026, assuming the acquisition closes as planned.
What Does This Mean for Interactive Strength?
The deal could transform Interactive Strength from a relatively small fitness equipment company into a broader multi-brand platform.
The potential portfolio would cover several major fitness categories:
Cycling → Wattbike
Rowing → Ergatta
Climbing → CLMBR
Strength & Digital Training → FORME
Stair Climbing → STEPR
This gives the company a much wider product ecosystem.
The bigger strategy is not simply to sell more stair climbers. It is to build a group of specialized fitness brands that can share technology, distribution, content, customers and operational resources.
What Does This Mean for STEPR?
For STEPR, joining Interactive Strength could provide access to more resources and a larger corporate platform.
STEPR can potentially benefit from:
- Greater distribution
- Additional retail expansion
- Access to new commercial customers
- More technology resources
- Cross-selling opportunities
- International expansion
- Additional capital for working capital and growth
At the same time, Interactive Strength has indicated that STEPR’s founders are expected to continue leading the business after the acquisition.
That could help preserve the operational knowledge and entrepreneurial approach that helped STEPR grow.
The Biggest Risks
The acquisition also carries risks.
Integration Risk
Managing five different brands is more complicated than managing one or two businesses.
Interactive Strength will need to integrate operations without damaging the individual brands.
Profitability Risk
The higher potential acquisition value depends heavily on future EBITDA performance.
If STEPR fails to achieve its targets, the additional consideration may be reduced, but weaker performance would still affect the overall growth strategy.
Financing and Dilution
Some consideration is being paid through TRNR preferred stock that can convert into common shares.
That creates potential dilution for existing shareholders if the preferred securities ultimately convert.
Acquisition Execution
The transaction has not yet closed.
The current agreement expects closing in Q4 2026 and includes customary closing conditions. Until completion, STEPR remains a pending acquisition rather than a fully integrated TRNR business.
What Investors Should Watch Next
The most important developments will be:
- Completion of the STEPR acquisition
- STEPR’s actual 2026 revenue
- STEPR’s EBITDA performance
- Progress toward the $4 million and $7 million EBITDA targets
- Interactive Strength’s consolidated profitability
- Revenue growth after the acquisition
- Potential additional acquisitions
- Share dilution from preferred-stock consideration
- Expansion of STEPR into commercial and retail channels
These factors will help determine whether the acquisition creates long-term value for Interactive Strength shareholders.
Final Analysis
Interactive Strength’s planned acquisition of STEPR is more than a simple purchase of a stair-climbing equipment company.
It is another step in TRNR’s strategy of building a multi-brand fitness equipment platform.
The deal is attractive on paper because STEPR is already generating revenue, is described as profitable, has established retail distribution and operates in a category that complements TRNR’s existing portfolio.
The most interesting part of the transaction is its performance-based structure. Interactive Strength is limiting the amount of value paid upfront while linking a large portion of potential consideration to STEPR’s future EBITDA and synergy performance.
If STEPR continues to grow and reaches its performance targets, the acquisition could help Interactive Strength move toward its goal of becoming a larger and more diversified fitness company.
However, investors should remember that the acquisition is still pending as of August 19, 2026. The real test will begin after closing, when Interactive Strength has to demonstrate that five different fitness brands can generate sustainable revenue growth, cash flow and profitability under one platform.
