Rallybio Corporation Reports Second Quarter 2021 Financial Results and Recent Business Highlights

Rallybio Corporation (Nasdaq: RLYB), a clinical-stage biotechnology company committed to identifying and accelerating the development of life-transforming therapies for patients with severe and rare diseases, today reported its financial results for the second quarter ended June 30, 2021 and provided an update on recent corporate developments.

“Since our founding in 2018, Rallybio has made consistent progress towards achieving our mission to truly transform the lives of patients with severe and rare diseases. With a tremendous team, we have now built a diversified portfolio of five programs, and we continue to work expeditiously to advance our pipeline,” said Martin Mackay, Ph.D., Chief Executive Officer of Rallybio. “Following the closing of our initial public offering in early August, we are operating from a position of financial strength, and we are poised to build on this momentum in the months ahead, with additional Phase 1/2 data for RLYB211 expected before year end, and the initiation of Phase 1 studies of RLYB212 and RLYB116 both planned for the first quarter of 2022.”

Rallybio’s current pipeline is focused on addressing diseases in the areas of hematology, immuno-inflammation, maternal fetal health, and metabolic disorders.

Recent 2021 Business Highlights:

• In July 2021, Phase 1/2 clinical proof-of-concept data for RLYB211 was presented at the International Society on Thrombosis and Haemostasis (ISTH) 2021 Virtual Congress. RLYB211 is a polyclonal anti-HPA-1a antibody in development for the prevention of fetal and neonatal alloimmune thrombocytopenia (FNAIT). The data presented at ISTH demonstrated the ability of an anti-HPA-1a antibody to rapidly and completely clear HPA-1a positive platelets from the circulation of HPA-1a negative participants. Based on these results, Rallybio believes that administration of an anti-HPA-1a antibody could be a viable approach for the prevention of FNAIT. In addition, treatment with RLYB211 was safe and well tolerated, and no serious adverse events were observed. The poster presentation can be accessed on Rallybio’s website here.
• In August 2021, Rallybio closed its initial public offering (IPO) of 7,130,000 shares of common stock at a public offering price of $13.00 per share. The aggregate gross proceeds to Rallybio from the offering were approximately $92.7 million, before deducting underwriting discounts, commissions and other offering expenses.

Upcoming Milestones:

• Rallybio is on-track to initiate a natural history study of FNAIT in the third quarter of 2021.
• Rallybio plans to announce additional clinical data from the ongoing Phase 1/2 clinical trial of RLYB211 in the fourth quarter of 2021.
• Rallybio remains on-track to initiate a Phase 1 study of RLYB212 in the first quarter of 2022. RLYB212 is a monoclonal anti-HPA-1a antibody in development for the prevention of FNAIT.
• Rallybio remains on-track to initiate a Phase 1 study of RLYB116 in the first quarter of 2022. RLYB116 is a novel, potentially long-acting, subcutaneously administered inhibitor of complement factor 5, or C5, in development for the treatment of patients with paroxysmal nocturnal hemoglobinuria (PNH) and generalized Myasthenia Gravis (gMG).

Second Quarter and First Half 2021 Financial Results:

• Research & Development (R&D) Expenses: R&D expenses were $6.8 million for the second quarter of 2021, compared to $3.1 million for the same period in 2020. For the six months ending June 30, 2021, R&D expenses were $15.9 million, compared to $5.0 million for the same period in 2020. This increase in R&D expenses for both the three and six months ended June 30, 2021 as compared to the same periods ended June 30, 2020 was primarily due to an increase in development costs associated with RLYB212 and RLYB116. In addition, for both the three and six months ended June 30, 2021 as compared to the same periods ended June 30, 2020, there was an increase in personnel-related costs, including equity-based compensation.
• General & Administrative (G&A) Expenses: G&A expenses were $3.7 million for the second quarter of 2021, compared to $1.6 million for the same period in 2020. For the six months ending June 30, 2021, G&A expenses were $7.5 million, compared to $3.5 million for the same period in 2020. The increase in G&A expenses for both the three and six months ended June 30, 2021 as compared to the same periods ended June 30, 2020 was primarily due to an increase in payroll and personnel-related costs, including equity-based compensation, primarily due to an increase in G&A related headcount and other professional fees associated with operating activities and preparations for becoming a public company.
• Net Loss Attributable to Common Units: Net loss was $11.1 million for the second quarter of 2021, or a net loss per common unit of $2.80, as compared to a net loss of $4.9 million for the second quarter of 2020, or a net loss per common unit of $1.85. Net loss was $24.4 million for six months ended June 30 2021, or a net loss per common unit of $6.77, as compared to a net loss of $8.8 million for the six months ended June 30 2020, or a net loss per common unit of $3.81. The net loss per common unit for all periods disclosed does not give effect to the completion of the Reorganization or the Company’s IPO that was closed in August 2021. See Financial tables for additional information on the Reorganization.
• Cash Position: As of June 30, 2021, cash, cash equivalents and short-term investments were $112.7 million. This amount does not include total net proceeds from the IPO of approximately $83.2 million, after deducting underwriting discounts, commissions and other offering expenses, which closed in August 2021.

Financial Tables

(1) Prior to our IPO, we operated as Rallybio Holdings, LLC, a Delaware limited liability company (Rallybio Holdings). On June 30, 2021, we completed a series of transactions pursuant to which (i) Rallybio IPD, LLC, a direct subsidiary of Rallybio Holdings, was converted from a Delaware limited liability company to a Delaware corporation and changed its name to Rallybio Corporation (the Corporation) and (ii) four direct subsidiaries of the Corporation, each a Delaware limited liability company ( collectively, the Merger Subs), each consummated a separate merger with one of Rallybio Holdings’ direct subsidiaries, other than Rallybio IPD, LLC (collectively, the Asset Subsidiaries), with the Asset Subsidiaries surviving the mergers and Rallybio Holdings receiving common stock of the Corporation in exchange for its interest in each Asset Subsidiary, which resulted in the Asset Subsidiaries becoming subsidiaries of the Corporation and the Corporation becoming the only direct subsidiary of Rallybio Holdings. On July 28, 2021, immediately prior to the completion of the IPO, Rallybio Holdings liquidated and distributed 100% of the capital stock of the Corporation, consisting solely of common stock, to the unitholders of Rallybio Holdings. The liquidation of Rallybio Holdings and distribution of the capital stock of the Corporation to the unitholders of Rallybio Holdings is referred to as the “Liquidation” and the Liquidation and these other transactions are collectively referred to as the “Reorganization.” As a result of the Reorganization, the unitholders of Rallybio Holdings became the holders of common stock of the Corporation, and our consolidated financial statements are subsequently reported from the Corporation. The unaudited condensed consolidated financial statements for the three and six months ended June 30, 2021 and 2020 are those of the Rallybio Holdings and do not give effect to the Reorganization.

(2) The net loss per common unit for all periods disclosed does not give effect to the completion of the Reorganization or the company’s IPO that was closed in August 2021.
