1. Like **Merck or Bristol Myers Squibb, but focused on developing drugs that block the CD47 'don't eat me' signal to fight cancer.**

2. Think of it as an **early Genentech, but specifically pioneering therapies that block the CD47 'don't eat me' pathway to treat cancer.**

• Evorpacept (ALX148): An investigational CD47 blocking therapeutic designed to enhance anti-tumor responses by preventing cancer cells from evading destruction by the immune system.

ALX Oncology (ALXO) is a clinical-stage biotechnology company focused on developing therapies for cancer. As such, the company does not currently have any commercial products approved for sale on the market.

Consequently, ALX Oncology does not have "major customers" in the traditional sense, as it does not generate revenue from the sale of products to other companies or to individuals. The company's operations are primarily funded through equity financing (investments from shareholders) and, to a much lesser extent, interest income and minor collaboration revenue related to its research and development activities.

While ALX Oncology engages in clinical trial collaborations with other pharmaceutical companies to advance its product candidates, these are partnerships for drug development rather than customer relationships involving the purchase of ALX Oncology's products. For example, ALX Oncology has collaborated with:

• Merck & Co., Inc. (NYSE: MRK) for clinical trials combining ALXO's investigational drug with Keytruda.
• Bristol-Myers Squibb (NYSE: BMY) for clinical trials combining ALXO's investigational drug with Opdivo and Yervoy.

However, these entities are collaborators providing study drugs or support, not customers purchasing ALX Oncology's commercial products. Therefore, ALX Oncology does not currently have major customers that purchase its products.

The ongoing clinical development by Pfizer of its CD47/SIRPα inhibitor, SI-6622 (formerly TTI-622), which is being investigated in overlapping oncology indications with ALX Oncology's lead product candidate, evorpacept. Pfizer's substantial resources and development capabilities represent a clear competitive threat in the emerging CD47 inhibition market.

Here are 3-5 expected drivers of future revenue growth for ALX Oncology (ALXO) over the next 2-3 years:

1. Advancement and Potential Commercialization of Evorpacept in HER2-Positive Breast Cancer: ALX Oncology is strategically focusing on the development of evorpacept, its lead CD47-targeting immunotherapy, particularly in HER2-positive breast cancer patients with high CD47 expression. The company has updated the Phase 2 ASPEN-Breast study to a CD47/HER2 biomarker-driven, single-arm design, aiming to accelerate enrollment and achieve an interim data readout in Q3 2026. This patient population represents a significant market opportunity, estimated at approximately 20,000 addressable patients and a $2-4 billion market. Successful clinical development and subsequent market approval would be a primary driver of revenue.
2. Launch and Growth of ALX2004: ALX2004, a novel EGFR-targeted antibody-drug conjugate (ADC), is a key pipeline candidate. The company initiated Phase 1 clinical trials for ALX2004 in mid-2025, with initial safety data anticipated in the first half of 2026. ALX Oncology considers ALX2004 a potentially best-in-class ADC for treating EGFR-expressing solid tumors, including non-small cell lung cancer, colorectal cancer, head and neck squamous cell carcinoma, and esophageal squamous cell carcinoma. The successful progression and eventual commercialization of ALX2004 would introduce a new product to the market and generate future revenue.
3. Expansion of Evorpacept into Additional Cancer Indications Driven by Biomarkers: ALX Oncology's strategy emphasizes biomarker-driven patient selection to improve clinical outcomes and development efficiency. Data from the ASPEN-06 trial in gastric cancer highlighted CD47 expression as a key predictive biomarker for a greater response to evorpacept. This insight is guiding their targeted clinical development strategy and supports the potential to pursue evorpacept in other solid tumor and hematologic malignancies where CD47 is broadly overexpressed. Expanding evorpacept's approved indications based on strong biomarker data would broaden its market reach and contribute to revenue growth.
4. Strategic Collaborations and Milestone Achievements: ALX Oncology engages in strategic collaborations, such as the UMBRELLA study with Sanofi evaluating evorpacept in combination with SARCLISA and dexamethasone for multiple myeloma, which has completed its randomized phase and is moving to dose optimization. Such partnerships can provide revenue through upfront payments, milestone achievements upon successful development stages, and potential future royalties or shared profits from commercialization.
