Thorough 11-month process, led by independent directors optimized the outcome for stockholders Board was highly engaged throughout the process and held 13 Board meetings to guide the Thoma Bravo negotiations and assess all potential alternatives At all times, the process focused on maximizing value for all stockholders and ensured that all stockholders were treated equally Fully evaluated the transaction against the Company's standalone plan, carefully considering the risks to that plan Evaluated the transaction against all other potential alternatives, none of which proved superior Limited number of potential strategic and financial suitors with interest and ability to consummate transaction One financial sponsor signed an NDA and indicated $61-$63/share for a consortium transaction following preliminary diligence, which did not proceed after the Board rejected this valuation Preliminary contact with two other parties (one strategic and one financial) did not result in further interest from those parties Negotiated the highest possible price from Thoma Bravo and resisted their late-stage attempt to lower the price Negotiated an 8% increase in offer price despite a 12% stock decline Rebuffed Thoma Bravo's last-minute price cut to $67.50/share over its concerns about execution risk on future revenue, margin expansion, and exit multiple following our 2Q 2025 earnings release Negotiated both a fiduciary out and a low termination fee of ~$2/share (~3%), minimizing the hurdle for other potential bidders to emerge post-announcement No topping bids have emerged 4 Executive Summary (continued) 3

Analysts Agree: The Price Delivers a Good Outcome for Stockholders… Source: Analyst Research, permission to use quotes neither sought nor obtained Analysts noted that a sale is in the best interest of Dayforce stockholders given challenges as a standalone company… …and $70/share exceeds analysts' expectations 8 1 "Dayforce currently trades at 4.2x CY26E revenue vs peers Paycom at 5.4x and Paylocity at 5.3x and compares with Paycor (acquired by Paychex) takeout multiple of 5.2x out year revenue. Assuming a takeout of 5.0x CY26E revenue, it would imply ~20% upside to Dayforce's current share price or ~$63" "If Thoma were to acquire DAY for a similar valuation to PYCR (~5x NTM EV/Rev), this would imply a price of ~$60 per share" "We believe the timing of a potential take-private makes sense as Dayforce was not necessarily getting much credit from investors for its stronger recurring revenue growth relative to HCM peers. We also believe that a take-private would allow Dayforce to clean up various investor questions around the story…" "We would see a potential private takeout as a good outcome for DAY…the company's cash flow generation, while improving, still lags peers significantly, which we believe has been a limiting factor for share performance in recent years" "We believe an acquisition was likely an ideal outcome for shareholders especially as competitors move down market driving increased risk of share erosion." 8/18/25 8/21/25 8/21/25 8/17/25 8/17/25 "We see ~5x CY26E revenue or low-30s FCF multiple as a reasonable outcome and would indicate roughly 20% upside from today's levels." 8/17/25

…and De-risks Stockholders From Continued Pressure on HCM Sector 9 "Investors we spoke with were wary of how weakening employment data and the likelihood for conservative outlooks around demand and interest rate cuts could impact guidance for these companies. We believe these questions are what led to the weak intra quarter stock performance for the HCM group (ADP, Dayforce, Paychex, Paycom, Paylocity, and Workday) with the average HCM company down 6.2% in June and July, compared to the S&P 500 and Russell 2000's performance of up 7.2% and 7.0%, respectively." 9/5/25 "Overall HCM Sector Backdrop: Investors have relayed some lack of willingness to have exposure within the HCM group due to the overall HCM sector backdrop. This includes moderating labor growth, lower near-term FF rate expectations (and thus larger resulting float revenue headwinds), decelerating growth by comps (suggesting slowing industry growth and or increasing competition), and an aversion to seat based revenue models amid fears of AI driven reductions to employment levels." 9/29/25 Source: Analyst Research, permission to use quotes neither sought nor obtained 1 "Multiples have de-rated over the past quarter as macro-related uncertainties appears to be manifesting in tempering buy-side expectations regarding the outlook for CY26. While our updated multiples are low relative to recent trend, they do not contemplate a recession, a scenario which would likely drive further downside" 10/14/25

Negative economic growth could also reduce HCM demand as client budgets are reduced DAY's seat-based revenue model is more sensitive to reductions in employee count and DAY's strong verticals are more recession vulnerable (e.g. hospitality, retail, etc.) The Bureau of Labor Statistics expects total employment to grow 3.1% from 2024-2034, nearly 10ppts slower than the 13% growth recorded over the 2014-24 decade1 Lower Interest Rates Low interest rates adversely affect high-margin float income DAY's float income makes up a greater percentage of Adj.
