Market Insights Snapshot
Simply Herb concentrated 68.68% of May 2026 sales in Flower, 24.67% in Vapor Pens, and 6.65% in Pre-Roll, while total brand sales were down 8.62% year over year and average price slipped 0.09%. Within the mix, Flower declined 11.95% YoY but rose 2.20% month over month, Vapor Pens were essentially flat year over year at -0.09% yet climbed 16.45% MoM, and Pre-Roll dipped 1.26% YoY with a 1.59% MoM contraction. The pattern implies a gradual pivot from a Flower-heavy base toward faster-recovering inhalables, as MoM momentum in Vapor Pens offsets YoY pressure in Flower and stabilizes overall share at 24.67% despite a 68.68% anchor in Flower.
Positionally, Simply Herb’s category tilt sets it up to defend high-volume Flower while leaning into Vapor Pens for near-term velocity, supported by a 2.20% MoM gain in Flower alongside a 16.45% MoM surge in Vapor Pens. With Pre-Roll share at 6.65% and a 1.59% MoM decline, the brand’s growth option sits in recapturing frequency within Vapor Pens and selective Flower SKU optimization, aiming to counter the 11.95% Flower YoY drop and the brand’s 8.62% YoY contraction. This mix suggests the brand can trade some Flower reliance for incremental pen penetration without materially eroding basket price, given average price erosion of only 0.09% YoY.
Competitive Landscape
Simply Herb sits at rank #5 in IL Flower in May 2026, down 1 position from #4 year over year and 2 positions from its March 2026 peak at #3, while also slipping 2 spots from #3 in February 2026 to #5 by May 2026. In contrast, High Supply / Supply held #1 year over year and remains #1 with a 29.8% YoY sales increase, and Good Green climbed from #6 to #3 alongside a 17.0% YoY sales rise, whereas RYTHM stayed at #2 despite a 12.2% YoY sales decline. This mix—competitors gaining share despite declines at #2 and growth powering advances at #3 and #4—implies Simply Herb’s downward rank drift from #3 to #5 is more about losing pace against faster risers than a broad market contraction.

Notable Products
Gorilla Chem (3.5g) led the downside in May 2026 with a -23.9% month-over-month drop and a rank of 2, signaling a pullback in Flower even as Vapor Pens held ranks 1, 3, and 4. Dungeons & Dragonfruit Distillate Cartridge (1g) rose 7.4% MoM at rank 1 while Fruity Loops Distillate Cartridge (1g) slipped -4.6% at rank 3, and four of the top ten are Vapor Pen SKUs, concentrating share at the top despite mixed single-digit moves. Watermelon Sugar Distillate Cartridge (1g) gained 13.5% MoM at rank 4 as Cherry Limeade Distillate Cartridge (1g) advanced 15.6% at rank 5, and LKY Charmz Oil Distillate Cartridge (1g) held rank 9 with $187,071, indicating that incremental cartridge gains are offsetting Flower volatility. The pattern implies Simply Herb is pivoting toward Vapor Pens as the volume anchor while Flower becomes a tactical, lower-consistency contributor.
