#### PRF Technologies Announces PRF-110 Demonstrated Sustained 72-Hour

#### Analgesic Activity Comparable to Approved, Commercially Available

#### Benchmark in Head-to-Head Preclinical Study
*Ropivacaine-only, NSAID-free formulation leverages a long-acting local anesthetic with a* 

*favorable safety profile*

**Tel Aviv – May 26, 2026 — PRF Technologies Ltd. (Nasdaq: PRFX) ("PRF" or the "Company")**, a clinical-stage specialty pharmaceutical company focused on reformulating established therapeutics for post-operative pain management, today announced positive results from a preclinical study in domestic pigs directly comparing its lead product candidate, PRF-110, to ZYNRELEF® (bupivacaine and meloxicam extended-release solution), an approved extended-release product used as a benchmark in the study.

PRF-110 is a proprietary, oil-based, viscous, clear extended-release formulation of ropivacaine designed to be deposited directly into the surgical wound bed prior to closure. The product candidate is being developed to provide prolonged local analgesia following surgery through a single administration at the surgical site. Such product is designed to reduce the use of opiates for post-surgical pain.

In the head-to-head preclinical study, PRF-110 demonstrated sustained analgesic activity comparable to ZYNRELEF across the 72-hour post-surgical evaluation period. Importantly, PRF-110 achieved this activity with a ropivacaine-only, NSAID-free formulation. Ropivacaine is a well-characterized long-acting local anesthetic that has demonstrated lower cardiac toxicity than bupivacaine in non-clinical pharmacology studies.

"For physicians, the key question is whether a new non-opioid therapy can provide sustained pain relief while offering a differentiated clinical profile," said Dr. Ehud Geller, Executive Chairman of PRF Technologies. "PRF-110 demonstrated sustained analgesic activity comparable to an approved benchmark over 72 hours in this head-to-head preclinical study. Importantly, PRF-110 achieved this activity with a ropivacaine-only, NSAID-free formulation. Given ropivacaine's demonstrated lower cardiac toxicity than bupivacaine in non-clinical pharmacology studies, we believe PRF-110's formulation profile may represent an important potential advantage as we evaluate the next steps in development."

Dr. Geller continued, "Post-operative pain remains a significant clinical and public health challenge, particularly as physicians and healthcare systems continue to seek effective ways to reduce reliance on opioids. Once successfully developed and approved, PRF-110 could provide physicians with an additional non-opioid option that combines sustained local analgesia, direct wound-bed administration and a differentiated formulation profile."

#### Study Design
The preclinical study was conducted in a validated pig incisional pain model, with von Frey methodology, used extensively to evaluate post-operative analgesic therapies. Animals were randomized to receive a single administration of either PRF-110 or ZYNRELEF into the surgical wound bed prior to closure. Pain-related endpoints were assessed at multiple timepoints over a 72-hour post-operative period.

Analgesic activity was evaluated using standard measures of incisional pain in pigs, including behavioral and functional parameters, as well as stimulus-evoked responses. The active treatment arms were assessed for magnitude and duration of analgesic effect across early and late post-operative time windows.

------

#### Key Results
• **PRF**-110 and ZYNRELEF each produced clear reductions in pain-related measures, confirming post-operative analgesic activity for both extended-release local analgesic formulations.

<br> • Across the overall 72-hour assessment period, PRF-110's analgesic effect was comparable to ZYNRELEF on the primary efficacy endpoints evaluated in this head-to-head preclinical setting.

<br> • At later post-operative timepoints, PRF-110 maintained analgesic efficacy comparable to ZYNRELEF, supporting the sustained-release characteristics of PRF-110 following a single administration.

<br> • PRF-110's safety and local tolerability profile in pigs was consistent with prior preclinical experience, with no unexpected findings observed at the doses tested.

PRF believes the findings provide useful supportive data as the Company evaluates the next steps for PRF-110's development and regulatory strategy. The Company believes the head-to-head comparison with an approved benchmark may help inform future development planning for PRF-110, including study design, formulation positioning and potential regulatory engagement.

#### About PRF-110
PRF-110 is a proprietary, oil-based, viscous, clear extended-release solution based on the local anesthetic ropivacaine and is being developed for the post-operative pain relief market. PRF-110 is designed to be deposited directly into the surgical wound bed prior to closure to provide localized and extended post-operative analgesia. The formulation is designed to remain in place at the surgical site, spread over and adhere to the wound surface, resist rapid clearance, and provide sustained local release of ropivacaine. PRF-110 is being developed to provide prolonged post-operative pain relief following a single administration, with the goal of reducing the need for repeated dosing and potentially reducing reliance on opioids after surgery.
