Upturn Scorecard

Upturn Star Rating

RLYB receives a 3-star rating, supported by solid company fundamentals. The rating is constrained by soft unit economics, soft analyst coverage, and limited analyst upside.

Company Fundamentals

RLYB has solid overall fundamentals (4 stars), with soft financial health, solid growth momentum, and solid ownership. In FY2025 versus FY2024, strong earnings growth (+84.5%) and solid revenue growth (+34.9%) are partially offset by soft cash generation (FCF margin -3474.7%), soft profitability (net margin -1046.4%).

Financial Health Rating

RLYB's financial health is supported by moderate liquidity, including working-capital and asset support (WC/assets 91.6%). Cash strength is soft (2 stars), which helps explain the 2-star overall score.

Growth Momentum Score

Earnings growth is RLYB's strongest growth driver at +84.5% FY2025 versus FY2024 (strong, 5 stars). Revenue growth (+34.9%, solid) and free-cash-flow growth (+39.5%, strong) are also constructive, though not equally high across every growth measure.

Ownership

Institutional ownership is 86.1% and approximately 33.1% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 24.20% supports management-shareholder alignment.

Unit Economics (Per $1K Revenue)

RLYB generates approximately $893 of gross profit, $-32,709 of operating income, and $-34,747 of free cash flow for every $1,000 of revenue. Based on FY2025 results. Strong cash conversion and healthy margins support the rating, although capital efficiency remains below the highest tier.

Economic Dimensions

Effective Tax Rate: 0.00%

Quantitative Style Profile

RLYB has a relatively low-volatility profile. Valuation that is moderately attractive rather than deeply discounted is the primary drawback.
